Abstract
Objectives Chronic constipation is a common gastrointestinal disorder, and management is crucial. Computed tomography (CT) is useful for evaluating rectal fecal mass but limited owing to radiation exposure, cost, and inaccessibility at certain facilities. Ultrasonography (US) avoids these pitfalls, but it is unknown whether it accurately assesses rectal feces. In this study, we evaluated the diagnostic performance of US compared with CT as the gold standard for assessing rectal feces. Methods We prospectively evaluated rectal fecal mass retention using US performed within 1 h of CT to assess the degree of agreement between methodologies. Rectal stool findings were evaluated on three levels: no stool (R1), presence of stool (R2), and hard stool filling (R3). Results The sample included 100 patients (55 men, 45 women), of whom 47 were constipated. The kappa coefficients for rectal content detection were excellent between US and CT (p <0.001). Eighty-two cases (R1: 46 cases; R2: 28 cases; R3: 8 cases) were matched with CT and US findings, and 18 were not. Cases that did not match had low urine or high gas volumes. CT and US findings showed high agreement in constipation (kappa coefficient 0.674, p <0.001) and non-constipation groups (kappa coefficient 0.677, p <0.001). All cases with R3 on CT were found in the constipation group, while more than half of the cases with R1 on CT were in the non-constipation group. Conclusions CT and US showed high agreement in evaluating rectal fecal mass retention, indicating that US can substitute CT.

Abstract
BACKGROUND Comprehensive genome profiling (CGP) serves as a guide for suitable genomically matched therapies for patients with cancer. However, little is known about the impact of the timing and types of cancer on the therapeutic benefit of CGP. MATERIALS AND METHODS A single hospital-based pan-cancer prospective study (TOP-GEAR; UMIN000011141) was conducted to examine the benefit of CGP with respect to the timing and types of cancer. Patients with advanced solid tumors (>30 types) who either progressed with or without standard treatments were genotyped using a single CGP test. The subjects were followed up for a median duration of 590 days to examine therapeutic response, using progression-free survival (PFS), PFS ratio, and factors associated with therapeutic response. RESULTS Among the 507 patients, 62 (12.2%) received matched therapies with an overall response rate (ORR) of 32.3%. The PFS ratios (≥1.3) were observed in 46.3% (19/41) of the evaluated patients. The proportion of subjects receiving such therapies in the rare cancer cohort was lower than that in the non-rare cancer cohort (9.6% and 17.4%, respectively; P = 0.010). However, ORR of the rare cancer patients was higher than that in the non-rare cancer cohort (43.8% and 20.0%, respectively; P = 0.046). Moreover, ORR of matched therapies in the first or second line after receiving the CGP test was higher than that in the third or later lines (62.5% and 21.7%, respectively; P = 0.003). Rare cancer and early-line treatment were significantly and independently associated with ORR of matched therapies in multivariable analysis (P = 0.017 and 0.004, respectively). CONCLUSION Patients with rare cancer preferentially benefited from tumor mutation profiling by increasing the chances of therapeutic response to matched therapies. Early-line treatments after profiling increase the therapeutic benefit, irrespective of tumor types.

Abstract
Objectives Gastric cancer can be diagnosed even in patients long after Helicobacter pylori eradication. Most cases involve intramucosal lesions; however, some are invasive and require surgery. To clarify appropriate long-term surveillance methods, this study compared invasive gastric cancer diagnosed ≥10 and <10 years after eradication. Methods This retrospective multicenter study included 14 institutions. We included 377 patients with gastric cancer with submucosal or deep invasion after surgical or endoscopic resection. Ordered logistic regression analysis was used to explore the factors contributing to the pathological stage and histological type. Results Invasive gastric cancer was detected in 84 patients (Group L) and 293 patients (Group S) ≥10 and <10 years after H. pylori eradication, respectively. Endoscopic mucosal atrophy at the time of cancer detection was similar in both groups; 50% of the patients had severe atrophy. Annual endoscopy correlated with early pathological stage (odds ratio [OR] 0.28, 95% confidence interval [CI] 0.14-0.54, p < 0.001). Group L exhibited an independent correlation with the advanced pathological stage (OR 2.27, 95% CI 1.06-4.88, p = 0.035) and the undifferentiated type (OR 2.12, 95% CI 1.16-3.90, p = 0.015). The pure differentiated type and early pathological stage significantly (p = 0.001) correlated with severe mucosal atrophy in Group S but not in Group L. Conclusions Invasive cancers diagnosed ≥10 years after H. pylori eradication were likely to be more malignant in histological type and pathological stage. Gastric cancer surveillance should continue regardless of endoscopic atrophy, particularly ≥10 years after eradication.

Abstract
BACKGROUND Linked color imaging (LCI) is a new image enhancement technology that facilitates the recognition of subtle differences in mucosal color. In the large-scale, multicenter randomized controlled trial LCI-FIND, LCI demonstrated good diagnostic performance for the detection of tumor lesions in the upper gastrointestinal tract. The aim of the present study was to exploratively evaluate the diagnostic performance of LCI according to H. pylori infection status as a subanalysis of LCI-FIND trial. METHODS The patients were randomly allocated to receive white light imaging (WLI) first, followed by LCI (WLI group), or vice versa (LCI group), and the two groups were compared for the detection of tumors. Data from this trial were analyzed by the presence/absence of H. pylori infection and further analyzed by successful or unsuccessful eradication in the H. pylori infection group. RESULTS The 752 patients in the WLI group and 750 patients in the LCI group who had participated in the LCI-FIND trial were included. In the successful eradication group, more gastric lesions were detected by primary mode in the LCI group than in the WLI group, indicating that more lesions were missed by WLI. Fisher's exact probability test for the comparison of the WLI and LCI groups yielded a p-value of 0.0068, with missed gastric lesions being detected 0.136 times (95% confidence interval: 0.020-0.923), significantly less with LCI than with WLI. CONCLUSION The current study suggests that LCI should be used for gastric cancer screening, particularly in patients with successful H. pylori eradication.

Abstract
BACKGROUND Clarithromycin (CAM) resistance is a major contributor to the failure to eradicate Helicobacter pylori (H. pylori). The mixed-infection ratio of CAM-susceptible and CAM-resistant H. pylori strains differs among individuals. Pyrosequencing analysis can be used to quantify gene mutations at position each 2142 and 2143 of the H. pylori 23S rRNA gene in intragastric fluid samples. Herein, we aimed to clarify the impact of the rate of mixed infection with CAM-susceptible and CAM-resistant H. pylori strains on the success rate of CAM-containing eradication therapy. MATERIALS AND METHODS Sixty-four H. pylori-positive participants who received CAM-based eradication therapy, also comprising vonoprazan and amoxicillin, were enrolled in this prospective cohort study. Biopsy and intragastric fluid samples were collected during esophagogastroduodenoscopy. H. pylori culture and CAM-susceptibility tests were performed on the biopsy samples, and real-time PCR and pyrosequencing analyses were performed on the intragastric fluid samples. The mutation rates and eradication success rates were compared. RESULTS The overall CAM-based eradication success rate was 84% (54/64): 62% (13/21) for CAM-resistant strains, and 95% (39/41) for CAM-sensitive strains. When the mutation rate of the 23S rRNA gene was 20% or lower for both positions (2142 and 2143), the eradication success rate was 90% or more. However, when the mutation rate was 20% or higher, the eradication success rate was lower (60%). CONCLUSIONS The mutation rate of the CAM-resistance gene was related to the success of eradication therapy, as determined via pyrosequencing analysis.

Abstract
Since the introduction of vonoprazan, a potassium-competitive acid blocker (P-CAB), it has been demonstrated to reversibly inhibit gastric acid secretion by engaging in potassium-competitive ionic binding to H+/K+-ATPase. In contrast, proton pump inhibitors (PPIs) achieve H+/K+-ATPase inhibition through covalent binding to cysteine residues of the proton pump. Reported cases have indicated an emerging trend of P-CAB-related gastropathies, similar to those associated with PPIs, as well as unique gastropathies specific to P-CAB use, such as the identification of web-like mucus. Pathologically, parietal cell profusions, which show a positively correlated with hypergastrinemia, have a higher incidence in P-CAB users compared to PPI users. Thus, this review aims to summarize the endoscopic and pathological findings reported to date concerning P-CAB-related gastric mucosal lesions. Additionally, it seeks to discuss the differences between the PPIs and P-CABs in terms of the formation and frequency of associated gastropathies. This review highlights the evident differences in the mechanism of action and potency of acid inhibition between P-CABs and PPIs, notably contributing to differences in the formation and frequency of associated gastropathies. It emphasizes the necessity to distinguish between P-CAB-related and PPI-related gastropathies in the clinical setting.

Abstract
BACKGROUND AND AIM There has been no report on a direct comparison between linked color imaging (LCI) and second-generation narrow-band imaging (2G-NBI) for surveillance of epithelial neoplasms in the upper gastrointestinal tract (UGIT). The aim of this study was to verify the superiority of LCI to 2G-NBI for surveillance esophagogastroduodenoscopy and to clarify how each endoscopic system should be used. METHODS This study was conducted as an open-label, two-arm-parallel (1:1), multicenter, randomized controlled trial at six institutions. Patients aged 20-85 years with a treatment history of epithelial neoplasms in the UGIT were recruited. Patients were assigned to a 2G-NBI group and an LCI group, and esophagogastroduodenoscopy was performed with primary image-enhanced endoscopy followed by white light imaging (WLI). The primary endpoint was the detection rate of one or more epithelial neoplasms in the primary image-enhanced endoscopy. A WLI-detected epithelial neoplasm was defined as a lesion that was detected in only WLI. RESULTS A total of 372 patients in the 2G-NBI group and 378 patients in the LCI group were analyzed. Epithelial neoplasms in the UGIT were detected by 2G-NBI in 18 patients (4.6%) and were detected by LCI in 20 patients (5.3%) (P = 0.87). WLI-detected epithelial neoplasms were in 11 patients in the 2G-NBI group (3.0%) and in 1 patient in the LCI group (0.27%) (P = 0.003). CONCLUSIONS Linked color imaging did not show superiority to 2G-NBI for the detection of epithelial neoplasms. Also, the percentage of WLI-detected epithelial neoplasms in primary NBI was significantly higher than that in primary LCI.

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND Antimicrobial therapy is necessary to eradicate Helicobacter pylori infection. The emergence of antimicrobial-resistant bacteria poses a threat to continued treatment with antimicrobial agents. For those who prescribe antimicrobial therapy, it is necessary to constantly monitor the emergence of antimicrobial-resistant bacteria. METHOD H. pylori clinical isolates were collected in Japan from August 2018 to December 2020 for antimicrobial susceptibility testing. The agar dilution method was used for the determination of the minimum inhibitory concentration (MIC) of clarithromycin (CLR), amoxicillin (AMX), metronidazole (MNZ), and sitafloxacin (STX). RESULTS MICs for 938 H. pylori isolates were examined. The primary resistance rates of H. pylori clinical isolates for CLR, AMX, MNZ, and STX in Japan were 35.5%, 2.7%, 4.2%, and 27.6%, respectively. The primary resistance rates for CLR, AMX, and MNZ were significantly higher than those of the 2002-2005 isolates. The resistance rate for CLR was significantly higher in females (males: 30.7%, females: 41.5%, p < 0.001) and higher in the ≤29 years age group (54.8%) than in the other age groups, although there were no significant differences (p = 0.104). The MNZ resistance rate was significantly higher in the ≤29 years age group than in the other age groups (p = 0.004). The resistance rate for STX increased with age, but a significant difference was only seen between the 30-49 years age group and the ≥70 years age group (p < 0.001), and the resistance rate was significantly higher in strains isolated in the Kyushu region than in the other regions (p < 0.001). CONCLUSIONS The primary resistance rates for CLR, AMX, and MNZ of H. pylori clinical isolates in Japan were higher than those of the 2002-2005 isolates. Continuous surveillance is needed to monitor the trends in antimicrobial-resistant H. pylori.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
Objective Of the highly accurate tests for current Helicobacter pylori infection, the urea breath test (UBT) and stool antigen test (SAT) are noninvasive and do not require endoscopy. We conducted a prospective study to evaluate the accuracy of the newly developed SAT in a medical checkup setting. Methods The accuracy of the proposed SAT was examined by determining H. pylori infection status based on a history of eradication therapy, endoscopic H. pylori infection diagnosis, and blood tests (serum H. pylori antibody, serum PG II) in individuals undergoing esophagogastroduodenoscopy (EGD) during a health checkup. Results The new SAT showed 97.3% (108/111) sensitivity for those "currently infected," as well as 99.3% (530/534), 98.0% (402/410), and 98.7% (932/944) specificity for those "never infected," those "previously infected," and those "never/previously infected", respectively. Conclusion The newly developed H. pylori SAT may be useful for diagnosing H. pylori infection. Patients should be suspected of being infected even after H. pylori eradication if they have a high cutoff index in this test.

Abstract
We held four upper gastrointestinal tract advanced diagnostic endoscopy sessions from the 89th to the 92nd Congress of the Japan Gastroenterological Endoscopy Society. The most common region addressed was the stomach in 25 presentations, followed by the esophagus in 23, duodenum in five, and other in one. Looking at techniques discussed, the most common image enhancement method discussed was narrowband imaging in 29 presentations, blue laser imaging, and linked color imaging (LCI) in 10 each, dual red imaging in three, and autofluorescence imaging in one. Furthermore, there were presentations of new techniques such as M-Chromo-LCI and acetic acid-indigo carmine mixture LCI. There were also six presentations regarding probe-based confocal laser endomicroscopy, and one of endocytoscopy techniques. We also saw presentations of images of gastric subepithelial tumors within the submucosa, 3D endoscopy, the development of computer-aided detection systems for early cancers, and fluorescent imaging.

Abstract
Objective To evaluate the efficacy and safety of rabeprazole coadministration with low-dose aspirin (LDA). Methods From 2015 to 2018, we conducted a large-scale, multicenter, prospective observational study to assess the safety and efficacy of treatment with rabeprazole (5 or 10 mg/day) in combination with LDA. Results The incidence of adverse reactions was 0.73% (11/1,513 patients), with no serious adverse reactions. We found no trend toward increases in the incidence of adverse reactions with increases in treatment duration. The cumulative recurrence rate of ulcers by Week 52 (Kaplan-Meier estimates) was 3.50% (range, 1.56-7.75%). No gastrointestinal bleeding was reported. Conclusion Rabeprazole in combination with LDA appears as safe and effective in real-world situations as in clinical trials.

Abstract
BACKGROUND AND AIM The aim of this post-hoc analysis in a randomized, controlled, multicenter trial was to evaluate the visibility of upper gastrointestinal (UGI) neoplasms detected using linked color imaging (LCI) compared with those detected using white light imaging (WLI). METHODS The visibility of the detected UGI neoplasm images obtained using both WLI and LCI was subjectively reviewed, and the median color difference (ΔE) between each lesion and the surrounding mucosa according to the CIE L*a*b* color space was evaluated objectively. Multivariate logistic regression analysis was performed to identify factors associated with neoplasms that were missed under WLI and detected under LCI. RESULTS A total of 120 neoplasms, including 10, 32, and 78 neoplasms in the pharynx, esophagus, and stomach, respectively, were analyzed in this study. LCI enhanced the visibility 80.9% and 93.6% of neoplasms in pharynx/esophagus and stomach compared with WLI, respectively. LCI also achieved a higher ΔE of enhanced neoplasms compared with WLI in the pharynx/esophagus and stomach. The median WLI ΔE values for gastric neoplasms missed under WLI and later detected under LCI were significantly lower than those for gastric neoplasms detected under WLI (8.2 vs 9.6, respectively). Furthermore, low levels of WLI ΔE (odds ratio [OR], 7.215) and high levels of LCI ΔE (OR, 22.202) were significantly associated with gastric neoplasms missed under WLI and later detected under LCI. CONCLUSION Color differences were independently associated with missing gastric neoplasms under WLI, suggesting that LCI has an obvious advantage over WLI in enhancing neoplastic visibility.

Abstract
BACKGROUND Although there are many Helicobacter pylori (H. pylori) diagnostic methods, the culture and antibiotic susceptibility test is an important method for selecting the most effective H. pylori eradication regimen. However, this diagnostic method is complicated and takes several days; therefore, the development of a rapid and simple diagnostic method is required. Eradication failure due to clarithromycin (CAM) resistance should also be considered. In this study, we report the clinical evaluation of point-of-care testing (POCT) kit using intragastric fluid, a novel kit for detecting H. pylori and CAM resistance. MATERIALS AND METHODS The study participants were 143 patients suspected of H. pylori infection and had an endoscopic examination. The novel diagnostic kit diagnosed H. pylori infection and CAM resistance-associated mutation using intragastric fluid. To diagnose H. pylori infection, the relationship between the diagnostic kit and conventional diagnostic methods (urea breath test, stool antigen test, culture test, and real-time polymerase chain reaction [PCR]) was evaluated. For CAM resistance-associated mutation detection, the concordance between the diagnostic kit and antibiotic susceptibility test was evaluated. RESULTS The diagnosis of H. pylori infection with the novel molecular diagnostic kit using intragastric fluid showed significant relationship with conventional diagnostic methods. Especially when the culture was control, the sensitivity was 100% (67/67), the specificity was 95.9% (71/74), and the overall concordance was 97.9% (138/141). The detection of CAM resistance-associated mutations had a concordance rate of 97.0% (65/67) when compared with the antibiotic susceptibility test. CONCLUSIONS The H. pylori molecular POCT kit uses intragastric fluid as a sample and can diagnose H. pylori infection and detect CAM resistance-associated mutations within an hour. This novel kit is expected to prove useful in selecting the most effective eradication regimen for H. pylori.

Abstract
A virulence bacterium, Helicobacter pylori, evolved parallel to its host human, therefore, can work as a marker for tracing the human migration. We found H. pylori strains indigenous in the southernmost islands of Japanese Archipelago, Okinawa, and defined them as hspOkinawa and hpRyukyu. Genome data of the strains revealed that hspOkinawa diverged from other East Asian strains about 20,000 years ago, and that hpRyukyu diverged about 45,000 years ago. The closest strains of hpRyukyu were found from Afghanistan, Punjab, and Nepal, which suggest this strain originated in the central Asia and traveled across the Eurasian continent during Paleolithic era. The divergence date of hpRyukyu corresponds with human fossil records in Okinawa. Although it is controversial from human DNA analyses whether descendants of the Paleolithic migrants remain in the modern Japanese population, this study reveals that the bacterium of Paleolithic origin remains in the stomachs of current Japanese.

Abstract
Abstract
Study question
In the management of male infertility, we investigated whether urological consultation could improve the live birth rate, and who should visit urologists in the setting of IVF clinic.
Summary answer
Urologic consultation resulted in improvement of semen quality and live birth rate with more IVF use in those with adverse semen parameters.
What is known already
Male factor infertility exists in about a half of infertility couples. This accounts for about 8% in male reproductive age. Therefore, ideally every male partner of infertility couples attempting conception should have a urological evaluation. However, it is not very easy to access urologists who specialized in reproductive medicine in Japan because we have very few of such urologists. One the other hand, a certain number of couples are wasting their time during IVF failure without urological evaluation.
Study design, size, duration
This is a single-institution retrospective study. We enrolled male partners of infertility couples who visited Kameda IVF clinic Makuhari, Chiba, Japan, between May 2016 and December 2020 and followed at least one year. Live birth rate and the frequency of IVF use were investigated according to semen quality and urological consultation status. Chi-square tests and T tests were used to compare the results between groups.
Participants/materials, setting, methods
Among 2225 couples who visited Kameda IVF clinic Makuhari, 803 male partners (Group A, 36.0%) were evaluated by urologists who were specialized in male reproductive medicine. Remaining 1422 patients did not (Group B, 64.0%). Lifestyle evaluation, physical examination, semen analyses, scrotal ultrasonography, blood test including sexual hormones and zinc concentration were performed in Group A. Semen analyses and lifestyle evaluation were performed in Group B. Urological treatments were done according to factors of male infertility.
Main results and the role of chance
Semen quality was worse in Group A as compared to Group B (sperm motility, 28.5±16.9% vs. 46.0±17.0%; total sperm count, 105±108 million/mL vs. 176±155; total motile sperm count, 34±49 vs.87±98; mean±S.D.; p = 0.0001, 0.0001, 0.0001, A vs. B, respectively). After urologic consultation and managements, sperm motility was improved to 34±18% (p = 0.001). Live birth rate in groups A and B were similar (56.0% vs. 57.2%), however couples who obtained a child in Group A used IVF more often than those in Group B (70% vs. 49.9%, p < 0.001). Among those with adverse semen quality (total motile sperm count less than 15.6 million/mL, n = 472), 350 visited urologists (Group 1, 74.2%) and remaining 122 did not (Group 2, 25.8%). Live birth rate in Group 1 was significantly better than in Group 2 (65.3% vs. 54.1%, p = 0.0359). Use of IVF was significantly more frequent in Group 1 than Group 2 (79.3% vs. 63.6%, p = 0.0359) among who obtained a child. In those with better semen quality (motile sperm count >50 million, n = 900), 119 visited urologist (31.1%, Group 3) and 781 did not (Group 4). Live birth rate and the use of IVF were not different between Groups 3 and 4 (51.1% vs.60.9%; 50.4% vs. 62.9%).
Limitations, reasons for caution
This study is a single-institution, retrospective study in the setting of IVF clinic. There may be a selection bias since men first visit gynecologists. These could affect the study results.
Wider implications of the findings
In the setting of IVF clinic, urologic consultation resulted in improved semen quality and better live birth rate with the use of IVF, especially in those who have adverse semen parameters. The results of this study encourage patients to see urologists and physicians to introduce urologist to patients.

Abstract
Abstract
Study question
What are the similarities and differences between the morphokinetics of abnormal, one- (1PN) and three-pronuclear (3PN) and normal bi-pronuclear (2PN) fertilisation?
Summary answer
The morphokinetic analysis of 1PN/3PN fertilisation reveals novel aspects of abnormal early development.
What is known already
Assisted reproduction technology has allowed the observation of early human development. Initially assessed statically at a single time point, fertilization has revealed its complexity once observed by Time-Lapse Microscopy (TLM). Detailed morphokinetic analysis of fertilisation has been reported in the last few years, unveiling previously unknown cytoplasmic phenomena (e.g. the cytoplasmic wave and halo) and the importance of cell symmetry for embryo development. At present, abnormal fertilization remains neglected, despite potential for understanding the physiology and pathology of early human development.
Study design, size, duration
This retrospective study involved TLM observation of normally (2PN, n = 2,685) and abnormally (1PN, n = 41; 3PN, n = 127) fertilised oocytes generated in ICSI cycles. Oocyte retrievals were carried out after the clomiphene citrate-based minimal ovarian stimulation, between October 2019 and December 2020. Oocytes of patients with different diagnoses of infertility were included in the analysis, while cases involving cryopreserved gametes or surgically retrieved sperm were excluded.
Participants/materials, setting, methods
Microinjected oocytes were assessed by a combined TLM-culture system (Embryoscope). Oocytes not suitable for TLM assessment, due to excess of residual corona cells or inadequate orientation for correct observation, were not analysed. Phenomena, relevant to meiotic resumption, pronuclear dynamics, cytoplasmic/cortical modifications, cleavage pattern, and embryo quality, were annotated and compared between groups.
Main results and the role of chance
Second polar body (PBII) extrusion was observed in all 1PN- and in a majority of 3PN-zygotes (92.1%). A 0.3-hour delay in PBII extrusion was confirmed in 3PN-zygotes (P = 0.0439). In a significant proportion of 3PN-zygotes, a third (female) PN formed from reabsorption of the PBII. The cytoplasmic wave was observed not only in 2PN- and 3PN-, but also in 1PN-zygotes. The presence and position of cytoplasmic halo were comparable among the three classes of zygotes. However, the duration of the cytoplasmic halo was prolonged in 1PN-zygotes (P < 0.0001). PN juxtaposition immediately before PN breakdown was less frequent in 3PN- compared with 2PN-zygotes (P = 0.0159). Furthermore, asynchronous PN breakdown was increased in 3PN- compared with 2PN-zygotes (P = 0.0026). The PN area of 1PN- was larger than that of 2PN-zygotes; however, the PN area of 3PN-zygotes was smaller than that of 2PN-zygotes. In 1PN-zygotes, a developmental delay was observed starting from the disappearance of the cytoplasmic halo, reaching 9 hours at the time of cleavage (P < 0.0001). A higher incidence of abnormal cleavage (P = 0.0019) and blastomere fragmentation (P < 0.0001) was observed in 1PN-zygotes. Cleavage progression was increasingly affected especially in 1PN-zygotes, resulting in blastocyst formation rates of 70.2%, 12.2% and 53.5% in 2PN-, 1PN- and 3PN-zygotes, respectively (P < 0.0001).
Limitations, reasons for caution
The study data derive from treatments carried out in a single centre. The study findings therefore require independent verification from other research groups.
Wider implications of the findings
These observations suggest that 1PN and 3PN fertilisation follow the general pattern of normal fertilization. Crucially, they also shed light on diverse and previously undescribed phenomena - e.g. reabsorption of the PBII in 3PN zygotes - underpinning the origins of abnormal fertilization and potentially clinically relevant.

Abstract
BackgroundLymphoproliferative disorders (LPDs), including malignant lymphoma, are known to occur in RA patients treated with disease modified antirheumatic drugs (DMARDs). In particular, LPD associated with methotrexate (MTX)-treated RA is often referred to as MTX-associated LPD (MTX-LPD). MTX-LPD have various clinical feature and histological findings1). We have accumulated MTX-LPD cases in patients with rheumatoid arthritis (MTX-RA-LPD).ObjectivesWe clarified the clinical characteristics of MTX-RA-LPD. In addition, we examine the prognosis of MTX-LPD in RA patients.MethodsWe enrolled 100 RA patients who diagnosed MTX-LPD from 2005 to 2021. We collected as follow data based on clinical reports retrospectively; 1) age, 2) gender, 3) duration from RA onset to LPD onset, 4) total dose of MTX, 5) duration of MTX administration, 6) presence of extranodal lesion 7) histological findings, 8) treatment for LPD, 9) 5-year survival rate.ResultsThe mean age of 100 MTX-RA-LPD patients (M:F=30:70) were 66.7 ± 10.7 years old, and the duration from RA onset to LPD onset were 25.2 ± 11.0 years. The total dose of MTX and duration of MTX administration were over 2,600mg and over 5 years, respectively. The extranodal lesions were found in 51%, and diffuse large B cell lymphoma was the most common histological findings. Spontaneous regression was observed in 68%. The 5-year survival rate of MTX-RA-LPD was as high as over 85%.ConclusionThe clinical features of MTX-RA-LPD were similar to those previous reports. Furthermore, we suggested a good prognosis for MTX-RA-LPD.References[1]Harigai M.

Abstract
BackgroundPatients with immune-mediated inflammatory diseases are inherently susceptible to infections and are at high risk of developing COVID-19. COVID-19 vaccination in patients with rheumatoid and musculoskeletal disease (RMD) is strongly recommended [1]. BNT162b2 is the most used COVID-19 vaccine in Japan. The safety and efficacy of this vaccine has been demonstrated in the general population [2], but patients receiving immunosuppressive therapy were excluded from the study. Although data on the immunogenicity of COVID-19 vaccine in the immunocompromised adult population is rapidly increasing, the immunogenicity of mRNA COVID-19 vaccine in RMD patients receiving medication has been reported in various and still inadequate ways. Furthermore, the immunogenicity of mRNA COVID-19 vaccine may vary depending on the medication. In addition, most of these data were reported from Western countries, and data on Japanese patients with RMD are limited.ObjectivesTo investigate serum antibody titre against SARS-CoV-2 spike protein following BNT162b2 vaccination in Japanese RMD patients on various immunomodulatory treatment.MethodsTwo hundred and twelve RMD outpatients undergoing treatment at Kagawa University Hospital and 43 healthy volunteers, who had received two doses of BNT162b2, were included in the study. Serum sample was collected at least 14 days after the second dose. Antibody titer against SARS-CoV-2 spike protein in serum was measured by ELISA (Elecsys Anti-SARS-CoV-2 S RUO). We analyzed the relationship between clinical characteristics, including the type of disease and treatment of RMD, and antibody titer against SARS-CoV-2 spike protein.ResultsThe antibody titer against SARS-CoV-2 spike protein in RMD patients was significantly lower than that in healthy subjects. In the analysis with therapeutic agents, the mean antibody titer in RMD patients treated with rituximab (RTX) was much lower than that in healthy controls. Patients treated with baricitinib, azathioprine, mycophenolate mofetil, abatacept, TNF inhibitors, cyclosporine, IL-6 inhibitors, methotrexate (MTX), or glucocorticoids (GC) had only moderately lower antibody titers. Patients treated with tacrolimus, an immunosuppressive drug commonly used for treatment in Japan, showed a slight decrease in antibody titer, but the difference was not significant compared with healthy subjects. IL-17 and IL-23 inhibitors did not impair the humoral response. In addition, the combination of MTX with various immunosuppressive agents reduced titers, although this was not statistically significant.ConclusionMany of the immunosuppressants impaired the immunogenicity to BNT162b2 in Japanese RMD patients. The degree of decline of antibody titers differed according to immunosuppressant. MTX potentially impairs the immunogenicity of BNT162b2 also in the case of concomitant use with other immunosuppressant.References[1]Curtis JR, et al.

Abstract
BackgroundThe conventional scoring methods of radiographic joint space narrowing (JSN) in rheumatoid arthritis (RA) such as the Genant-modified Sharp score (GSS) are widely accepted but include subjective and time-consuming nature1. Therefore, we have developed an in-house software equipped with partial image phase-only correlation (PIPOC)2 which can automatically quantify joint space width (JSW) change.ObjectivesThe purpose of this study was to investigate whether the in-house software can predict the inhibitory effect of tocilizumab on joint destruction in a short period of time.MethodsThe study included 39 RA patients (35 female) who were treated with tocilizumab (Table 1). Radiological progression of the metacarpophalangeal and the proximal interphalangeal joints was evaluated according to the GSS at 0, 6, and 12 months. Automatic measurement was performed by the in-house software (Figure 1). We then validated in-house software in terms of accuracy in detecting the JSN.Figure 1.The algorithm flow of in-house software equipped with PIPOCTable 1.Clinical characteristics of RA patientsvariablebaseline6 months12 monthsTotal number of patients39Sex, female/male35/4Rheumatoid factor status, positive/negative29/10Age, mean (SD) years61.5 (14.6)Duration of disease, mean (SD) months111.4 (85.0)Swollen joint count, mean (SD)6.0 (4.7)3.5 (3.5)2.9 (4.0)Tender joint count, mean (SD)6.4 (3.5)2.9 (2.2)1.9 (2.0)DAS28-ESR, mean (SD)4.9 (1.2)3.0 (1.1)2.6 (1.0)DAS28-CRP, mean (SD)4.4 (1.1)3.0 (0.9)2.6 (0.8)RA, rheumatoid arthritis; SD, standard deviation; DAS28, disease activity score with 28 joints; ESR, erythrocyte sedimentation rate; CRP, C-reactive proteinResultsTo ensure homogeneity of the subjects, we targeted the joints with GSS = 0 at baseline in the software analysis. The success rate of the in-house software for JSW measurement was 96.8% (449/464). Here, the GSS (+)/PIPOC (+) were defined as joints with JSN progression according to the GSS and the software analysis, respectively. Otherwise, joints were defined as the GSS (-)/PIPOC (-) namely non-progressive JSN. The 0–12-month GSS with the 0–6-month GSS (+) group was significantly more JSN progression than the 0–6-month GSS (-) group (Mann-Whitney U test, p < 0.001). Similarly, the 0–12-month PIPOC with the 0–6-month PIPOC (+) group was significantly more JSN progression than the 0–6-month PIPOC (-) group (p < 0.001). The 0–12-month JSW change of finger joints with the 0–12-month GSS (+) detected by the in-house software was significantly greater than the 0–12-month GSS (-) (p = 0.02).ConclusionOur in-house software equipped with PIPOC might be able to predict the subsequent joint destruction with 6 months observations.References[1]Genant HK, et al: Assessment of rheumatoid arthritis using a modified scoring method on digitized and original radiographs.

Abstract
BackgroundApremilast has been shown to be effective in patients with Behçet’s disease (BD) in domains other than oral ulcers; however, its long-term efficacy is yet to be determined. Although serum cytokine modulation by increasing intracellular cAMP levels has been suggested as a mechanism for the efficacy of apremilast on skin areas of psoriasis [1], the relationship between efficacy and cytokine on various domains in BD has not been fully investigated.ObjectivesThis study aims to evaluate the long-term clinical efficacy of apremilast in BD and its effect on serum cytokines.MethodsIn this study, patients with BD who received apremilast for active oral ulcers were included. For 12 months, the improvement rates of oral and genital ulcers, skin lesions, and arthritis were assessed every three months. Serum levels of cytokines, including interferon-gamma (IFN-γ), interleukin 10 (IL-10), and IL-17A were determined using Simple Plex (Protein Simple, CA, USA) at baseline and three months after apremilast treatment. Other cytokines, including tumor necrosis factor-alpha (TNF-a), IL-6, IL-8, and IL-23, were also measured in serum using a multiplex immunoassay (Luminex Assay, R&D Systems).ResultsFifteen patients were included in this study. Table 1 shows the characteristics of the patients who participated in this study. Oral ulcers disappeared in 66.7% and 92.3% of the patients after 3 and 6 months of apremilast treatment, respectively. Genital ulcers disappeared in all patients after 6 months of apremilast treatment and were maintained for 12 months. The efficacy of apremilast in oral ulcers could be divided between two groups: 8 patients in the oral ulcer remission group (OU-R group) whose oral ulcers completely disappeared after 3 months of apremilast administration and persisted for 1 year, and 7 patients in the oral ulcer non-remission group (OU-NR group) whose oral ulcers persisted after 3 months of apremilast treatment. Genital ulcers improved more rapidly in the OU-R group than in the OU-NR group, and completely disappeared within 3 months. Skin and joint lesions generally improved after 6 months, but recurred after 9 months.Table 1.Baseline characteristics of the studied patients with Behçet’s diseaseCharacteristicsN = 15Age (years), mean ± SD46.7 ± 13.0Sex (female), n (%)11 (73.3)Disease duration (years), mean ± SD10.4 ± 8.8Active Behçet’s disease manifestation at the time of enrollment, n (%) Oral ulcer15 (100) Genital ulcer5 (33.3) Skin lesion (erythema nodosum or pustules)10 (66.7) Arthralgia9 (60.0) Arthritis5 (33.3) Ocular involvement0 (0) Gastrointestinal involvement1 (6.7) Neurological involvement0 (0) Vascular involvement0 (0)SD, standard deviation; n, number.Serum cytokines could be analyzed in seven of the 15 cases. There was no significant association between serum baseline cytokine levels and the presence of lesions or severity of disease. Compared to baseline, TNF-α and IL-23 levels were significantly lower after apremilast treatment and IFN-γ levels were trending upwards; however, IL-6, IL-8, and IL-10 levels showed no constant trend (TNF-α and IL-23: p <0.05, IFN-γ: p = 0.078). In addition, the rate of decrease in serum IL-6, IL-10, and IL-23 levels was significantly greater in the OU-R group than in the OU-NR group (Figure 1). However, the rate of change in serum cytokines was not associated with efficacy of apremilast for skin lesions, arthralgia, or arthritis.Figure 1.The rate of change in serum interleukin (IL)-6, IL-10, and IL-23 levels up to 3 months after apremilast treatment in the oral ulcer remission group and the oral ulcer non-remission group.ConclusionApremilast has shown long-term efficacy in the treatment of oral and genital ulcers in patients with BD. The efficacy of apremilast against oral ulcers in BD may be attributed to its modulatory effect on serum cytokines as previously reported. Future exploratory studies for biomarkers associated with the presence of efficacy against genital ulcer and arthritis are needed.References[1]Gottlieb AB, Matheson RT, Menter AM, et al.

Abstract
BackgroundTakayasu arteritis (TAK), a granulomatous large vessel vasculitis, mainly involves the aorta and its proximal branches and commonly occurs in young females. However, studies of pregnancy in women with TAK are sparse and limited, probably due to the rarity of the disease.ObjectivesThe purpose of this study was to understand the status quo of medical treatments of the primary disease and outcomes of pregnancy in patients with TAK, and birth outcomes of the children in Japan.MethodsPatients with TAK who conceived after the onset of the disease and were managed at medical facilities participating in the Japan Research Committee of the Ministry of Health, Labour, and Welfare for Intractable Vasculitis (JPVAS) were retrospectively enrolled in this study. The following information was collected from patients who had a live-born baby: age at diagnosis of TAK, disease classification, age at delivery, treatments before and during pregnancy, complications during pregnancy, birth outcomes of the children, and changes in disease activity during pregnancy and after delivery.ResultsFifty-one cases and 69 pregnancies from 19 ethics committee-approved centers were enrolled during the study period 2019–2021. Of these, 49 cases and 66 pregnancies (95.7%) resulted in delivery and live-born babies. The Numano classification of the 49 cases was as follows: type I, 11; type IIa, 15; type IIb,12; type III, 1; type IV, 1; type V, 9; with type IIa being the most common. The age of diagnosis was 22 years (13–37 years, year of diagnosis 1965–2017), the median age of the delivery of 66 pregnancies was 31 years (year of delivery 1969-2021), and the median duration of illness at delivery was nine years. There were 34 planned pregnancies (51.5%, including four pregnancies by artificial insemination/ovulation induction). Preconception therapy included prednisolone (PSL) in 51 pregnancies (77.3%, median dose 7.5 mg (range 4–30 mg)/day), immunosuppressive drugs in 18 pregnancies (27.3%, azathioprine 8, tacrolimus 7, methotrexate 4, cyclosporin A 1, and colchicine 1), biologics in 12 pregnancies (18.1%, infliximab 6, tocilizumab 5, and adalimumab 1), antihypertensive drugs in 5 pregnancies (7.6%). Surgical treatment had been performed before pregnancy in 6 cases (aortic root replacement 2, subclavian artery dilatation 1, subclavian artery bypass 1, subclavian artery stenting 1, and ascending aorta semicircular artery replacement 1). Medications used during the course of pregnancy included PSL in 48 pregnancies (72.7%, median dose 8 mg (range 4–30 mg)/day, increased in 13 pregnancies, decreased in 1 pregnancy), immunosuppressants in 13 pregnancies (19.7%, azathioprine 6, tacrolimus 6, and cyclosporin A 1), biologics 9 pregnancies (13.6%, infliximab 4, tocilizumab 4, and adalimumab 1). Immunosuppressants and biologics were discontinued in five and four pregnancies after conception. Complications during pregnancy were observed in 20 pregnancies (30.3%), with hypertension being the most common. Complications related to TAK or its treatment were severe infections in two pregnancies and aneurysm enlargement due to increased circulating plasma volume in one pregnancy. Aortic arch replacement was performed after delivery for the latter case. Relapse of TAK was observed in 4 pregnancies (6.1%) during pregnancy and in 8 pregnancies (12.1%) after delivery. One pregnancy resulted in restenosis of subclavian artery for which dilatation procedure was performed prior to the pregnancy. There were 13/66 (19.7%) preterm infants and 17/59 (28.8%) low birth weight infants; all but one had a birth weight of more than 2,000 g and no had serious postnatal abnormalities. Forty-three (82.7%) of the 52 confirmed infants were breastfeed fully or mixed.ConclusionMost of the pregnancies in patients with TAK were successfully delivered while they had low disease activity at a dose of less than 10 mg/day of PSL. Relapse occurred during pregnancy and after delivery in some cases. The babies tended to have low birth weight, but 82.7% of them were breastfed without serious complications.Disclosure of InterestsTakako Miyamae: None declared, Yusuke Manabe: None declared, takahiko sugihara Speakers bureau: TS has received honoraria from Abbvie Japan Co., Ltd., AsahiKASEI Co., Ltd., Astellas Pharma Inc., Ayumi Pharmaceutical, Bristol Myers Squibb K.K., Chugai Pharmaceutical Co., Ltd., Eli Lilly Japan K.K., Mitsubishi-Tanabe Pharma Co., Ono Pharmaceutical, Pfizer Japan Inc., Takeda Pharmaceutical Co.

Abstract
BackgroundHydroxychloroquine (HCQ) therapy is recommended as a baseline treatment for all patients with systemic lupus erythematosus (SLE) due to its various benefits (1). However, it is not clear to what extent HCQ contributes to improvement in SLE patients with stable disease activity. It has also been reported that HCQ is effective in improving the prognosis of life caused by atherosclerotic lesions in SLE, but the mechanism of this effect has not been fully elucidated.ObjectivesThe purpose of this study was to determine the benefit of additional HCQ administration in SLE with controlled disease activity, who achieved the sustained LLDAS.MethodsThe study included patients with SLE who started additional HCQ treatment between January 2016 and December 2019 at our institution, those who sustained LLDAS achievement for at least 3 months prior to starting HCQ treatment. These patients did not change their immunosuppressant and glucocorticoid regimens for more than three months after starting HCQ. The effect of HCQ was assessed at the beginning and 3 months after administration. The disease activity was measured by SELENA-SLEDAI, SLE-DAS, and immunoserological parameters including serum complement levels and anti-DNA antibodies. The factors that are known to associated with pathogenesis of atherosclerosis, such as serum TNF-α, IL-6, IL-8, MCP-1, adiponectin, leptin, resistin, S100A8, and S100A9, were measured by ELISA.ResultsOf the 110 SLE patients who received additional HCQ at our institution, 27 patients who had achieved LLDAS from at least 3 months prior to HCQ administration were included in this study. Patient characteristics are represented in Table 1. SLEDAI scores, SLE-DAS scores and serum anti-dsDNA antibodies were observed to be significantly reduced after HCQ treatment compared to baseline. After 3 months of HCQ treatment, serum lipid markers such as triglyceride (TG), low-density lipoprotein (LDL) cholesterol and atherosclerotic index, which are associated with the development of atherosclerosis, were significantly reduced compared to baseline (TG, LDL and atherosclerotic index: p<0.05). Cytokines such as TNF-α, IL-6, MCP-1, S100A8, S100A9, leptin, and resistin were found to be significantly decreased, and serum adiponectin was significantly increased. (TNF-α, IL-6, MCP-1, leptin: p < 0.05. S100A8, S100A9, adiponectin, resistin: p < 0.0001, Figure 1).Table 1.Characteristics of patients with SLE enrolled in this study.CharacteristicsN = 27Female, no.

The gray lines show the values for individual patients, and the thick red line shows the average value. P-values were determined using the Wilcoxon signed-rank test. A p-value of less than 0.05 was considered statistically significant.ConclusionThe addition of HCQ medication to SLE patients who achieve the clinical therapeutic goal of LLDAS without HCQ may prevent progression of atherosclerosis in addition to further reducing disease activity.References[1]Fanouriakis A, Kostopoulou M, Alunno A, et al.

Abstract
BackgroundThe management of rheumatoid arthritis (RA) has been transformed by the use of molecular targeted therapies. Early treatment and treat-to-target approach leads to good clinical response and remission (responders), but not in all patients.Environmental factors including diet contribute to the development, activity and severity of RA. Evidence from clinical trials suggested that dietary interventions, such as Mediterranean diet or supplementation with fish oil rich in n-3 polyunsaturated fatty acids (n-3 PUFA), have positive effects on RA. Japanese and Mediterranean diets are associated with longevity and characterized by high fish intake. Clinical studies have identified predictors of treatment response in individual RA patients, however, the influence of fish consumption on treatment response in RA patients treated with targeted therapies has not been elucidated.ObjectivesTo assess whether fish consumption is associated with a good response to targeted therapies in RA patients with Japanese and Mediterranean dietary patterns.MethodsThe study is a collaborative international cross-sectional retrospective study enrolling patients with RA on treatment with biologics or JAK inhibitors attending to Hokkaido University Hospital, Japan or Hospital Virgen de las Nieves, Spain.Enrolled patients were asked to complete a brief-type self-administered diet history questionnaire (BDHQ) and a detailed fish frequency questionnaire (DFFQ) referring to consumption frequency in the previous month. At study entry, alcohol consumption, tobacco habits, educational level and employment status were recorded and RA disease activity evaluated by qualified rheumatologists. Demographic, clinical/laboratory data were retrospectively extracted from the medical records.By December 2021, 279 patients (Japan 217, Spain 62) returned the questionnaires. A preliminary analysis was carried out with the first 58 Japanese patients in which all clinical and laboratory data could be collected. A descriptive analysis was performed and the relative risks approximated by odds ratios.ResultsFifty-eight Japanese RA patients, 45 females, median age at entry 66 yrs [IQR 54-73], median disease duration 11yrs [IQR 7-20] were included in this analysis. Fifty-three (93%) of patients were on biologic therapies and four (7%) on JAK inhibitors with a median treatment duration of 4.5 yrs [IQR 1-7]. Concomitant treatment with conventional DMARDS and glucocorticoids were reported in 69% and 48% of patients, respectively. Forty-two (72%) patients were responders to treatment defined as DASESR ≦3.2. Another systemic autoimmune disease, hypertension, diabetes mellitus, dyslipidemia or gout history were present in 29%, 29%, 9%, 33% and 10% of patients, respectively.All patients had consumption of fish in the last month and an intake of n3-PUFA rich fish (fatty fish) was indicated by 82% (<1 time/week 34%, ≧ 1 time/week 48%).The patients’ fatty and non-fatty fish intake scores were calculated with a mathematical formula based on the intake of each of the fish included in the DFFQ and number of responses. In the group of high fatty fish score patients (≧ 1 time/week) 94% were responders to treatment vs. 6% non-responders, [OR 8.75, CI [1.0-73.54, p= 0.022] while only 63% of patients in the high non-fatty fish score group respond to the treatment.ConclusionFatty fish intake associated with a good response to treatment in patients receiving targeted therapies, suggesting that fish consumption may have some beneficial effects on RA treatment.ReferencesThere is no reference.AcknowledgementsAcknowledgements to Ms. Y.

Abstract
BackgroundHypertrophic pachymeningitis (HP), characterized by an inflammatory disorder indicating intracranial or spinal thickening of dura mater, is found to develop as a neurological involvement in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Meanwhile, the previous studies focusing on HP in AAV have been reported as a single-institution study, and the analyses were performed in a small number of patients because HP is a rare neurological disorder. Therefore, neither etiological nor clinical characteristics of HP in AAV have been adequately elucidated.ObjectivesThis study clarified the characteristics of HP in AAV by analyzing the information of multicenter study in Japan (Japan collaborative registry of ANCA-associated vasculitis: J-CANVAS).MethodsWe analyzed the clinical information from 541 Asian patients with AAV enrolled in J-CANVAS. Of them, newly diagnosed and relapsed AAV were included in 448 and 93, respectively. The epidemiological and clinical findings were compared between patients with and without HP. Clinical manifestations related to AAV were evaluated based on the Birmingham Vasculitis Activity Score version 3. To elucidate independent factors in HP development, logistic regression analyses were additionally performed.ResultsOf the total 541 patients (mean age: 71±14 years, M:F = 1:1.2), HP was demonstrated in 28 (5.17%), including 17 (3.79%) in newly diagnosed AAV and 11 (11.8%) in relapsed AAV. The classification of granulomatosis with polyangiitis (GPA) was significantly higher in patients with HP than those without HP (50% vs. 21%, p = 0.0007). In newly diagnosed AAV, patients with HP significantly had higher GPA classification and higher positivity for PR3-ANCA than those without HP (53% vs. 17%, p = 0.001; 29% vs. 9%, p = 0.015, respectively). Conversely, positivity for MPO-ANCA was significantly higher in patients with HP than those without HP in relapsed AAV (91% vs. 55%, p = 0.025), despite not significantly different in the classification of AAV. Headache and cranial neuropathies were significant neurological symptoms in patients with HP compared to those without HP (82% vs. 6.6%, p < 0.0001; 32% vs. 2.9%, p < 0.0001, respectively). Besides, ear, nose and throat (ENT) and mucous membranes/eyes were significantly higher involvements in patients with HP than in those without HP (54% vs. 26%, p = 0.003; 29% vs. 9%, p = 0.003, respectively). Moreover, higher complications of “conjunctive hearing loss” and “sudden visual loss”, which are included in the categories of ENT and mucous membranes/eyes involvement, respectively, were significantly indicated in patients with HP than those without HP (39% vs. 7.2%, p < 0.0001; 21% vs. 1.2%, p < 0.0001, respectively). Multivariable logistic regression analysis identified that ENT (odds ratio [OR] 1.28, 95% confident interval [CI] 1.09 to 1.49, p = 0.002) and mucous membranes/eyes involvement (OR 1.37, CI 1.14 to 1.65, p = 0.0006), as well as conjunctive hearing loss (OR 4.52, CI 1.56 to 13.05, p = 0.005) and sudden visual loss (OR 1.84, CI 1.12 to 3.00, p = 0.015), were independent related factors in patients with HP.ConclusionGPA could be significantly classified in patients with HP. Notably, patients with HP significantly showed higher positivity for PR3-ANCA than those without HP in newly diagnosed AAV. Furthermore, sudden visual loss and conjunctive hearing loss might be implicated in HP development.Disclosure of InterestsNone declared

Abstract
BackgroundMyositis-associated antibodies (MAA) and myositis-specific antibodies (MSA) have been associated with clinical manifestations of dermatomyositis and polyneuropathy, including interstitial lung disease (ILD), myopathy, malignancy, arthritis, and skin rashes. Among them, anti-ARS and anti-MDA5 antibodies are strongly associated with complications of ILD that are associated with life expectancy. It has been reported that anti-Ro52 antibody affects severity of myositis and ILD. (1) Based on these findings, it is possible that autoantibodies possessing features of ILD associated with dermatomyositis and polymyositis may be predictive.ObjectivesThe purpose of this study is to clarify the relationship between MSA/MAA and clinical features of ILD complicated by dermatomyositis and polymyositis.MethodsWe retrospectively analyzed IIMs patients diagnosed according to Peter & Bohan’s diagnostic criteria in our hospital from 2011 to 2018. The presence of 14 MSA / MAA (Jo1, PL12, PL7, EJ, OJ, KS, Mi2, MDA5, TIF1γ, SRP, PM-Scl70, 100, Ku, Ro52) was measured using ELISA (MESACUP, MBL, Japan) and line blot (EUROLINE myositis profile3, EUROimmun, Germany). Clinical characteristics, including HRCT imaging findings, were extracted from medical records. HRCT imaging findings were analyzed by multiple radiologists. The association between the extracted clinical features and the MSA / MAA held was analyzed.ResultsSeventy-eight cases of IIM were included in the analysis. The frequency of ILD complications was 53/78 (68%), and 60% of ILD complications were ARS antibody positive. The complication rate of ILD in MDA5- and ARS-positive cases was 100% (3/3 cases) and 94% (32/34 cases), respectively. These MDA5- and ARS-positive patients with ILD had rapidly progressive ILD. One of the three MDA5 antibody-positive RPILD cases died, but none of the four ARS antibody-positive RPILD cases died. However, in patients with multiple MSA or MAA including ARS, three case had rapidly progressive ILD, and none died. n the analysis of the presence of Ro52 antibody, it was detected in 46% (36 cases) of all cases, but in 74% of anti-ARS antibody positive cases.In the analysis of ILD patterns by radiologists using HRCT, fibrosing NSIP (fNSIP), fibrosing OP (fOP), and UIP were the most frequent in that order. analysis of the association between ILD patterns and MSA / MAA showed that there was no MSA / MAA associated with each ILD pattern. No MSA/MAA was found to be associated with each ILD pattern. ARS antibody-associated ILD, the most common type of ILD, had a worse prognosis than other MSA / MAA positive ILD. Death due to ILD was observed in 5 patients (PL7: 3cases, PL12: 1case, PM-Scl75: 1case). Oxygen was required for ILD progression in 3 Jo1-positive patients, 1 PL7-positive patients, and 1 PL12-positive patient, respectively. The frequency of UIP, which is considered to have a poor prognosis in other rheumatic diseases, was higher in patients with anti-ARS and anti-Ro52 antibodies.ConclusionThe prognosis of anti-ARS antibody-positive lLD associated with dermatomyositis and polymyositis was associated with fibrosis by analysis of HRCT patterns, and the prognosis was confirmed to be poor.In addition, the UIP pattern, which is strongly associated with fibrosis, was found to be associated with anti-Ro52 antibody. In the treatment of ILD, which is strongly associated with the prognosis of dermatomyositis and polymyositis, it may be necessary to consider antifibrotic treatment for patients with anti-ARS antibody and anti-Ro52 antibody positivity.References[1]Tamara Vojinovic et al.

Abstract
BACKGROUND Eradication treatment for Helicobacter pylori gastritis is covered by national health insurance since 2013 in Japan. However, eradication failure due to the increase of antimicrobial resistance has become a serious problem. The present study aims to establish a reference panel of Japanese H. pylori strains for antimicrobial susceptibility testing. METHOD A total of 28 strains were collected from 4 medical facilities in Japan. Antimicrobial susceptibility tests (ASTs) to clarithromycin (CLR), amoxicillin (AMX), and metronidazole (MNZ), were used to select standard reference strains. Complete genome sequences were also determined. RESULTS Three H. pylori strains (JSHR3, JSHR6 and JSHR31) were selected as standard reference strains by the Japanese Society for Helicobacter Research (JSHR). The minimum inhibitory concentrations (MICs) of the antibiotics against these 3 strains by agar dilution method with Brucella-based horse-serum-containing agar medium were as follows: JSHR3 (CLR 16 μg/ml, AMX 0.032 μg/ml and MNZ 4 μg/ml), JSHR6 (CLR 0.016 μg/ml, AMX 0.032 μg/ml and MNZ 4 μg/ml), and JSHR31 (CLR 16 μg/ml, AMX 1 μg/ml and MNZ 64 μg/ml). CONCLUSIONS A reference panel of H. pylori JSHR strains was established. The panel consisted of JSHR6, which was antibiotic-susceptible, JSHR3, which was CLR-resistant, and JSHR31, which was multi-resistant. This reference panel will be essential for standardized ASTs before the optimal drugs are selected for eradication treatment.

Abstract
BackgroundCytomegalovirus (CMV) has been associated with atherosclerosis in patients with chronic renal failure, and may cause secondary nephrotic syndrome. Therefore, we hypothesized that the reactivation of CMV by immunosuppressive therapy in patients with vasculitis may affect renal function.ObjectivesThe purpose of this study was to investigate relationships between CMV infection and renal function during ANCA-associated vasculitis remission induction therapy.MethodsThis retrospective cohort study enrolled microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA), and eosinophilic granulomatosis with polyangiitis patients at 25 sites in Japan who had a first or severe relapse between January 2017 and June 2020. Of these, patients with MPA or GPA who had a positive renal lesion score on BVAS (version 3) at baseline, or vasculitis findings on renal biopsy, CMV assayed by 48 weeks of treatment, were included. Patients were divided into two groups based on the presence or absence of a positive CMV antigen test during the remission induction phase (0–48 weeks of treatment). Outcomes were the rate of change in estimated glomerular filtration rate (eGFR) at 48 weeks after initiation of treatment in both groups, as determined by (eGFR at 48 weeks - eGFR at the initiation of treatment)/eGFR at the initiation of treatment; where lower values were associated with worse renal function. General linear models adjusted for age, gender, presence of diabetes or chronic kidney disease, and the use of rituximab or cyclophosphamide were generated.ResultsA total of 387 patients had CMV antigen measured during ANCA-associated vasculitis treatment, of which 164 had renal involvement and eGFR measured at 48 weeks. Seventy-seven (47.0%) were male and the median age was 75 years (range 69–80 years). CMV reactivation was observed in 44 patients (26.8%). The beta coefficient of multiple regression analysis with CMV positive as 1 and negative as 0 was 0.08 (95% confidence interval -0.13 to 0.29) (p = 0.47). The rate of change in eGFR was higher in the CMV positive group, but not statistically significantly.ConclusionContrary to our hypothesis, renal prognoses tended to be better when CMV reactivation was observed. The patients in the CMV reactivation group may have been treated more aggressively, and some patients with a poor prognosis who were not followed up for 48 weeks dropped out. Further research investigating the adjustment of treatment methods is required.Disclosure of InterestsNone declared

Abstract
BackgroundAntineutrophil cytoplasmic antibody -associated vasculitis (AAV) is usually treated with combination of high-dose glucocorticoid (GC) and immunosuppressive agents, followed by tapering GC dose. Although the European League Against Rheumatism (EULAR) has specific recommendations for tapering the GC dose, clinicians often taper it slower than recommended due to concerns of potential disease relapse. However, such slower taper may prolong GC exposure for the patients, increasing the risk of adverse events, particularly infection.ObjectivesThe aims of our study were (1) to clarify GC dose tapering in the treatment of AAV in a real-world setting, in contrast to the EULAR recommendation of 2015 and (2) to compare the incidence of AAV relapse and severe infection between patients underdoing EULAR-recommended tapering and those undergoing slower tapering than the recommendation.MethodsIn this multicenter (25 sites in Japan), observational, retrospective study of AAV, 541 patients who had initial or severe relapse were enrolled between January 2017 and June 2020. Of these, 349 patients with microscopic polyangiitis (MPA) or granulomatosis with polyangiitis (GPA) who entered in GC tapering phase after successful induction treatment were included. These patients were then grouped on the pace of GC tapering, defined as the GC dose at 12 weeks after treatment initiation: (1) EULAR group: 7.5-10 mg/day of GC, according to the EULAR recommendation of 2015, and (2) SLOWER group: >10 mg/day of GC. Their baseline characteristics and clinical outcomes were compared. Primary outcome was defined as relapse-free days from treatment initiation, whereas secondary outcome included the incidence of infectious events requiring hospitalization within 48 weeks from treatment initiation. Multivariable analysis was performed to assess the relationship between tapering pace and clinical outcomes.ResultsThere were 44 patients (12.6%) in the EULAR group and 290 (83.2%) in the SLOWER group. Regarding baseline characteristics, compared with the EULAR group, the SLOWER group had significantly higher serum C-reactive protein level (EULAR, 5.89 ± 6.89 mg/dL vs SLOWER, 7.56 ± 6.01 mg/dL; p = 0.03), as well as a trend toward higher Birmingham Vasculitis Activity Score (version 3) (EULAR, 11.80 ± 7.01 SLOWER, 13.93 ± 7.06; p = 0.08) We did not observe any significant differences in the frequency of relapses between the two groups (EULAR, 8/44, 18.2% vs SLOWER, 55/290, 19.0%; p = 0.63). Multivariable Cox proportional hazard analysis revealed no relationship GC dose at 12 weeks from treatment initiation and incidence of relapse. However, upon logistic regression analysis, the SLOWER group was found to have significant higher risk of a severe infectious event within 48 weeks from treatment initiation (p = 0.046; hazard ratio, 1.27; 95% confidence interval, 1.004 – 1.601).ConclusionOur finding indicates that clinicians tended to taper GC slower for patients with higher disease activity. However, slower GC taper was not found to reduce the frequency of relapse. In addition, slower GC taper was found to increase the risk of a severe infection. Hence, clinicians should pay attention not only relapsing but also late GC taper resulting in the risk of serious infection, especially in patients with higher disease activity of AAV.References[1]Eur J Clin Invest 2015;45 (3): 346–368.[2]Rheumatology (Oxford). 2021 Dec 24;61(1):205-212.[3]Arthritis Res Ther. 2021 Mar 20;23(1):90.[4]Scand J Rheumatol. 2022 Jan 20;1-13.[5]J Rheumatol. 2018 Apr;45(4):521-528.[6]Rheumatol Adv Pract. 2021 Mar 9;5(3):rkab018.[7]Ann Rheum Dis. 2016 Sep;75(9):1583-94.Figure 1.AcknowledgementsWe would like to thank Editage (www.editage.com) for English language editing.Disclosure of InterestsNone declared

Abstract
BackgroundBelimumab (BEL), a monoclonal antibody against the soluble counterpart of B-cell activating factor (BAFF) has been recommended to be added in patients with SLE who do not respond adequately to standard therapy [1]. In addition to antibody production, belimumab may also affect other functions of B cells, such as antigen presentation and excretion of inflammatory cytokines. Belimumab may also have an effect on immune cells other than B cells, as they express BAFF receptors. These facts suggest that BEL administration in SLE may have an effect on various pathological conditions including cytokine production, not just antibody production. However, there are few reports on whether cytokine production is actually related to the efficacy of BEL administration in SLE.ObjectivesThe purpose of this study was to determine the efficacy of BEL administration in patients with SLE and its effect on cytokines.MethodsPatients with SLE who were started on BEL between December 2018 and December 2021 at our institution were included in this study. We retrospectively analyzed the reasons for additional BEL administration, adverse events, disease activity indicators (SLE Disease Activity Index (SLEDAI)-2K, lupus low disease activity state (LLDAS) achievement rate, anti-dsDNA antibody titer, serum complement titer, and treatment agents including glucocorticoid dose. Serum cytokine (interferon-alpha, interleukin (IL)-6, IL-10, and IL-17A) levels were measured using ELISA at the start of BEL administration, 3 months, and 6 months later.ResultsFive cases of SLE were included in the study. Four of the five patients were female, with a mean age of 51.4±9.6 years and a mean duration of disease of 17.4±10.0 years.The reasons for additional BEL administration were glucocorticoid reduction in five patients, refractory pericarditis in one patient, skin rash and arthritis in two patients, and immunological activity in two patients. Four of the five patients had decreased renal function below eGFR50 at the baseline. Concomitant medications at the time of BEL induction included steroids in five patients (mean prednisolone dose 12.2±12.2 mg/day), hydroxychloroquine in three patients, mycophenolate mofetil in three patients, tacrolimus in one patient, and methotrexate in one patient. The mean disease activity before the introduction of BEL was SLEDAI 4±4, and LLDAS was achieved in three patients.Twelve weeks after the start of BEL treatment, two patients had improved SLEDAI, including one patient who achieved LLDAS.Immunological activity parameters improved in one of the two patients.However, two patients flared after BEL administration and were treated with increased glucocorticoid doses.One patient with SLE on hemodialysis had thrombocytopenia, an adverse event that may have been related to belimumab treatment.ConclusionAt our institution, BEL was additionally administered to SLE patients with refractory disease and was effective; with the exception of one case. Serum cytokine analysis before and after BEL treatment will be included in the discussion.References[1]Fanouriakis A, Kostopoulou M, Alunno A, et al. 2019 update of the EULAR recommendations for the management of systemic lupus erythematosus.

Abstract
BackgroundWith the availability of multiple Jak inhibitors (JAKi) for treatment, patients with RA who have had inadequate response to conventional therapies, including biologics, can now achieve favorable outcomes such as remission and low disease activity.However, it is also true that no single JAKi therapy is effective for all RA.Some RA treatment guidelines recommend a switch strategy from current JAKi to other JAKi or biologics in patients with inadequate response to JAKi therapy [1].There is insufficient evidence to support the efficacy of switching to another JAKi in patients with inadequate JAKi response (JAKi-IR).ObjectivesThe aim of this study is to clarify the effectiveness of the strategy of controlling disease activity by switching to other JAKi in RA cases with JAKi-IR and to analyze the effect on serum cytokines related to the pathogenesis of RA.MethodsRA patients who switched to other JAKi during treatment with JAKi between September 2017 and January 2022 were included in this retrospective study.The clinical characteristics of the included RA patients were collected from their medical records.The efficacy of the JAKi switch strategy was assessed by changes in composite measure scores of disease activity, including DAS28-CRP, SDAI, and CDAI, at 4 and 12 weeks after the switch.In addition, changes of serum cytokines associated with RA pathogenesis (IL-6, TNF-α) were measured and analyzed by ELISA (Simple Plex, Protein Simple).ResultsTwenty-nine RA patients who received the JAKi switch treatment strategy were included in the analysis. The clinical characteristics of the included patients are shown in Table 1. All patients were receiving JAKi due to inadequate response to biologics. JAKi were switched to control disease activity including 3 cases (10%) who achieved temporary remission.Table 1.Baseline characteristics of the 29 patients enrolled this studyClinical characteristicsn=29Age57 [48.0-66.0]Sex (F/M)22/7 (75.9)Disease duration, years13 [8.6-18.8]RF positive26 (89.7)ACPA positive, (n=22)20(90.0)Concomitant medicationsMethotrexate, dose(mg/week)10 (34.5), 8.0 [6.0-10.5]Corticosteroid, dose(mg/day)17 (59.0), 4.0 [2.0-5.0]Disease activity DAS28-CRP3.77 [3.2-4.6] SDAI15.5 [9.8-21.1] CDAI14.5 [9.5-20.0]Patient global assessment of disease activity (mm)40 [25-58]Provider global assessment of disease activity (mm)32 [15-40]CRP (mg/dl)0.9 [0.1-1.7]TJC/SJC4 [2-5], 2[2-5]Date are n (%) or median [IQR].Figure 1 shows the effect of the JAKi switch strategy on the disease activity category.Evaluation using SDAI showed that 65% of patients achieved the immediate treatment goal of low disease activity at 4 weeks after switch, and 69% of patients maintained this goal at 12 weeks. SDAI remission was also observed in 17% of patients at 4 weeks and 31% at 12 weeks, demonstrating the efficacy of the JAKi switch strategy. The efficacy of the JAKi switch strategy was also observed in other measures of disease activity.Changes in serum cytokines (IL-6, TNF-α) associated with disease activity in RA before and after JAKi switch were analyzed in 10 patients. Regardless of the type of JAKi, serum IL-6 was decreased by JAKi switch in most cases at 12weeks (average change of serum IL-6: -27.25pg/ml).However, no trend was observed for changes in serum TNF- disease acti(average change of serum TNF-ed for change).There was no clear association between changes in these two cytokines and the efficacy of the JAKi switch strategy.ConclusionThe composite disease activity index showed that about 60% of JAKi-IR patients achieved low disease activity, one of the treatment goals, at 4 weeks after switching to JAKi, and the effect was maintained up to 12 weeks. This effect did not appear to be related to the type of JAKi.The effects of biologic therapy on serum cytokines associated with RA activity differed from the effects of the JAKi switch strategy.References[1]György Nagy, et al.

Abstract
BackgroundPregnancies complicated by a number of rheumatic diseases are known to be at high risk for the occurrence of adverse pregnancy outcomes (APOs). There have been several reports on the risk of APOs in systemic lupus erythematosus and rheumatoid arthritis, but few reports on polymyositis (PM)/dermatomyositis (DM) pregnancies. There are also insufficient reports on changes in the activity of PM/DM during pregnancy. Based on the findings reported in other rheumatic diseases, it is suggested that increased activity during pregnancy is associated with APOs in PM/DM (1-3).However, the risk factors for pregnancy outcome in pregnancies complicated by PM/DM, including the presence or absence of worsening of disease activity, have not been clarified.ObjectivesThe purpose of this study was to analyze a case series of PM/DM complicated pregnancies in a single center to determine the changes in disease activity during pregnancy and pregnancy outcomes.MethodsPM/DM patients who were managed from pregnancy to delivery at Kagawa University Hospital from March 2006 to May 2021 were included in this study. Clinical indices including duration of illness, disease activity, and treatment were extracted from medical records and retrospectively analyzed for association with pregnancy outcome.ResultsEight PM/DM pregnancies were included in the analysis. The mean age at delivery was 28.3±3.8 years and the mean duration of disease was 6.3±3.2 years.Treatment at the time of pregnancy included glucocorticoids (GC) in 7 cases and immunosuppressive drugs in 5 cases.Creatinine phosphokinase (CK) levels were normal in all patients at the time of pregnancy, but increased during pregnancy in 4 (50%) patients. These 4 patients with elevated CK required treatment with increasing doses of GC, and the mean GC dose during pregnancy was 10.9 ± 6.0 mg/day.Table 1 shows the pregnancy outcomes of the 8 patients. There was one spontaneous abortion and seven live births. Among the live births, 2 were preterm and 4 were low birth weight. The mean gestational age at delivery was 35.3±5.2 weeks and the mean birth weight was 2297.7±1041.4g.Table 1.Pregnancy outcomes of eight casesCase no.OutcomeMode of deliveryGestational age at delivery (weeks)Birth weight of the newborn (grams)Adverse pregnancy outcomes1Live birthCesarean section26590Preterm birth, LFD, HELLP syndrome2Spontaneous abortion3Live birthTransvaginal delivery301,299Preterm birth, LBW4Live birthCesarean section382,765Hypertensive disorder5Live birthTransvaginal delivery373,290−6Live birthTransvaginal delivery372,492LBW7Live birthTransvaginal delivery393,456−8Live birthTransvaginal delivery402,192LBW7 live births 1 abortion35.3±5.22,297.7±1,041.4The birth outcomes of the 2 patients who received continuous immunosuppressive therapy were full-term and normal weight infants. APOs, such as preterm delivery and low birth weight, occurred in cases with increased CK levels and increased GC doses.ConclusionIn pregnancies of PM/DM patients, pregnancy outcome was less than favorable.An association between disease activity and the development of APOs during pregnancy in PM/DM was suggested. An association was also suggested between GC dose and the risk of developing APOs.As in other rheumatic disease pregnancies, continued use of pregnancy-appropriate immunosuppressive drugs and control of disease activity with lower glucocorticoid doses in PM/DM pregnancies may be important to achieve good pregnancy outcomes.References[1]Nagy-Vincze M, Vencovsky J, Lundberg IE, Danko K (2014) Pregnancy outcome in idiopathic inflammatory myopathy patients in a multicenter study.

Abstract
BackgroundWomen with systemic lupus erythematosus (SLE) are known to have more difficulty in achieving a successful pregnancy than healthy women. They have a higher risk for adverse pregnancy outcomes (APOs) including preterm birth (PB), low birth weight (LBW). (1,2). Many reports revealed that these APOs are related to uncontrolled high disease activity (3,4). Therefore, it is important for SLE women who hope to conceive to control disease activity strictly. However, it is not clear to what extent disease activity should be strictly controlled, including serum parameters such as complement levels and anti-dsDNA antibodies.ObjectivesThe purpose of this study was to determine whether disease activity parameters at conception could be a risk factor for PB or LBW among APOs in patients with SLE.MethodsDisease activity parameters including SLEDAI score, LLDAS achievement rate, serum complement levels (C3, C4, CH50), and anti-dsDNA antibody titer were retrospectively collected from medical records. We then collected information related to each APOs (PB and LBW), and analyzed the association with disease activity parameters.ResultsThe subjects were 60 pregnancies of 45 patients. As for a comprehensive disease activity index at conception, SLEDAI score or the rate of LLDAS achievement became risk factors for PB (both of p<0.01, Table 1), and SLEDAI score was also a risk factor for LBW (P=0.04, Table 1). Analysis of immunological disease activity parameters showed that low C3 or high titer of anti-dsDNA antibody were risk factors for PB (P=0.03 and 0.01, respectively, Table 1). In the logistic regression analysis of PB, the cut-off levels of C3 and anti-dsDNA antibody were 62 mg/dl and 5.4 IU/ml, respectively (Figure 1 [1]-A, [1]-D). The risk of PB was significantly higher in the cases with low serum C3 and high anti-dsDNA antibody titer at conception (P=0.02).Similarly, low C3 or CH50 were risk factors for LBW (P=0.02 and 0.03, respectively, Table 1). Logistic regression analysis for LBW showed the cut-off level of C3 as 87 mg/dl, and CH50 as 41.8 IU/ml (Figure 1 [2]-A, [2]-C). Cases with low C3 and low CH50 were at higher risk for LBW (P=0.03).Table 1.Association between disease activity parameters and PB or LBWPreterm birth (PB)Low birth weight (LBW)PB (+)(n = 14)PB (-)(n = 46)P valueLBW (+)(n = 23)LBW (-)(n = 37)P value Achievement of LLDAS, n (%)##5 (41.7)30 (71.4)0.0912 (63.2)23 (65.7)1.00 Achievement of LLDAS without a glucocorticoid dose, n (%)##5 (41.7)37 (88.1)< 0.01*13 (68.4)29 (82.9)0.31 SLEDAI score#3.5±2.91.1±1.3<0.01*2.3±2.11.3±2.00.04* C3, mg/dl#77.3±19.094.7±21.20.03*80.5±16.396.7±22.70.02* C4, mg/dl#16.1±9.019.2±6.30.1617.6±6.319.1±7.40.56 CH50, IU/ml#37.3±10.641.1±8.50.1736.5±6.642.2±9.70.03* Anti-dsDNA antibody, IU/ml#32.5±68.55.5±11.10.01*20.7±55.87.0±12.20.34(Values are presented as mean ± standard deviation or number (%). #Wilcoxon rank sum test; ##Fisher’s exact test; *P < 0.05.)Figure 1.Logistic regression analysis of cut-off value of PB and LBW for C3, C4, CH50 and anti-dsDNA antibody.(ROC curves based on logistic regression analysis of cut-off levels for disease activity parameters, including C3, C4, CH50, and anti-dsDNA antibody titer.

Abstract
Primary duodenal adenocarcinoma is a rare malignancy whose carbonic anhydrase IX (CA9) expression remains poorly understood. A 73-year-old man visited our hospital for a medical checkup. Transnasal endoscopy revealed a submucosal, tumor-like lesion with a central depression located in the descending part of the duodenum on white light imaging. On texture and color enhancement imaging mode 1, the lesion was highlighted as a reddish, elevated lesion with an irregular mucosa in its central depressed area. Pancreaticoduodenectomy was performed on the suspicion of duodenal adenocarcinoma for biopsy and endoscopic diagnosis, which led to the lesion being diagnosed as tubular adenocarcinoma, pT1b (SM). Immunohistological staining revealed an adenocarcinomatous component positive for CA9, as well as a normal duodenal mucosa. To our knowledge, this report is among the first to describe CA9-expressing primary duodenal adenocarcinoma.

Abstract
Fitz-Hugh-Curtis syndrome (FHCS) is a rare complication of pelvic inflammatory disease and its MRI findings remain poorly described. A 34-year-old woman was raced to our hospital with slight fever and severe right upper quadrant pain. Gadoxetic acid-enhanced magnetic resonance imaging revealed high-intensity regions in the surface and subcapsule of the right liver on T2-weighted imaging and on diffusion-weighted imaging. A definitive diagnosis of FHCS was confirmed based on high titers of serum IgA and IgG antibodies to Chlamydia trachomatis. She was treated with oral azithromycin and discharged 6 days after admission with improvement of her symptoms. To our knowledge, this report represents a valuable addition to the FHCS literature describing MRI findings in the early stage of FHCS onset.

Abstract
The revised 2014 Japanese Guidelines for Gastric Cancer Screening approved gastric endoscopy for use in population-based screening. Thus, it is expected that gastric cancer will be detected earlier, and gastric cancer mortality further decreased, with the widespread use of endoscopy and Helicobacter pylori eradication therapy. However, due to an increasingly aging population and relatively low gastric cancer screening rates, gastric cancer remains the leading cause of cancer death in Japan. While the era of endoscopic gastric cancer screening has begun, it does present challenges, such as limited/varying regional availability of endoscopists. This review describes the history of gastric cancer screening in Japan, achievements in endoscopic gastric cancer screening in Japan and Korea, efforts underway to improve screening by stratifying individuals according to gastric cancer risk, and initiatives by the Japan Gastroenterological Endoscopy Society aimed at improving screening, including the implementation of a board certification program for screening endoscopists.

Abstract
BACKGROUND Vonoprazan is a potassium competitive acid blocker used to treat erosive gastroesophageal reflux disease (GERD) with stronger, more stable acid-suppressing effects than proton pump inhibitors (PPIs). This study clarified the usefulness and superiority of vonoprazan administered every second day over PPIs in the maintenance therapy of erosive GERD. METHODS This is a prospective, multicenter, open-label, two-period randomized cross-over study. Patients were randomized to either the vonoprazan-lansoprazole (VP-LZ) group, who were given vonoprazan 10 mg for the first 4 weeks and then lansoprazole 15 mg for the next 4 weeks both administered once every second day, or the lansoprazole-vonoprazan (LZ-VP) group, who were treated in reverse. GERD symptoms were compared using symptom diaries, the frequency scale for symptoms of GERD (FSSG), and the gastrointestinal symptom rating scale (GSRS). RESULTS We enrolled 122 patients between December 2017 and May 2019. Symptoms were well controlled in vonoprazan administration and lansoprazole administration were 93.6% and 82.1%, respectively, with a significant difference on McNemar's test (P = 0.003). During the second 4 weeks, 94.4% and 76.7% of patients in the VP-LZ and LZ-VP groups, respectively, were well controlled following for ≥ 6 consecutive days a week (P = 0.009). During the first 4 weeks, 96.7% and 80.0% of patients were well controlled with < 1 weekly in the VP-LZ and LZ-VP groups, respectively, during the first 4 weeks (P = 0.007). GERD symptoms, assessed via FSSG and GSRS, significantly decreased with vonoprazan administration once every second day. CONCLUSIONS Vonoprazan administered once every second day could be an effective alternative to PPIs in the maintenance treatment of erosive GERD (UMIN000030393).

Abstract
Chronic constipation is a common gastrointestinal disorder in older adults, and it is very important to manage chronic constipation. However, evaluating these subjective symptoms is extremely difficult in cases where patients are unable to express their symptoms because of a cognitive or physical impairment. Hence, it is necessary to observe the patient’s colonic faecal retention using objective methods. Ultrasonography observation for colonic faecal retention is useful for diagnosing constipation and evaluating the effectiveness of treatment. Since there was no standard protocol for interpreting rectal ultrasonography findings, we developed an observation protocol through an expert consensus. We convened a group of experts in the diagnosis and evaluation of chronic constipation and ultrasonography to discuss and review the current literature on this matter. Together, they composed a succinct, evidence-based observation protocol for rectal faecal retention using ultrasonography. We created an observation protocol to enhance the quality and accuracy of diagnosis of chronic constipation, especially rectal constipation. This consensus statement is intended to serve as a guide for physicians, laboratory technicians and nurses who do not specialise in ultrasound or the diagnosis of chronic constipation.

Abstract
Background and study aims Linked color imaging (LCI) is a new image-enhancing technique that facilitates the differentiation of slight differences in mucosal color tone. We performed an exploratory analysis to evaluate the diagnostic capability of LCI in ultraslim endoscopy, using data from patients examined in the LCI-Further Improving Neoplasm Detection in upper gastrointestinal (LCI-FIND) trial, a large-scale, multicenter, randomized controlled trial that demonstrated the capability of LCI for detecting neoplastic lesions in the upper gastrointestinal tract. Patients and methods Data from the LCI-FIND prospective trial were used. In the LCI-FIND trial, 1502 patients with a history of gastrointestinal cancer were randomly assigned to two groups based on examination methods: white light imaging (WLI) followed by LCI (WLI group) and LCI followed by WLI (LCI group). The present exploratory analysis investigated the outcomes of patients who underwent ultraslim and standard endoscopies. Results Ultraslim endoscopes were used in 223 patients and standard endoscopes in 1279 patients. The primary endpoint of the LCI-FIND trial was the percentage of patients diagnosed with a neoplastic lesion using WLI or LCI. The corresponding percentage tended to be higher with LCI than with WLI among patients who underwent ultraslim endoscopy and among those who underwent standard endoscopy; the crude risk ratio was 2.21 [95 % confidence interval (CI): 1.06-4.67], and the adjusted odds ratio was 2.46 (95 % CI: 1.07-5.63). Conclusions Our exploratory analysis of data from the LCI-FIND trial showed that LCI is useful in identifying neoplastic lesions, when used in ultraslim endoscopy.

Abstract
The Japan Gastroenterological Endoscopy Society held four serial symposia between 2019 and 2020 on the state-of-the-art of issues related to upper GI inflammatory diseases. This review discusses some of the topics addressed in these symposia. The papers regarding nonerosive reflux disease, recent improvements in intraesophageal pH-impedance monitoring and endoscopic diagnosis using image-enhanced endoscopy have been published. Many publications have addressed its usefulness in endoscopic treatment of gastroesophageal reflux disease such as anti-reflux mucosectomy. In the management of eosinophilic esophagitis, since the symptoms are subjective, objective indicators have been sought, and ultrasonography and high-resolution manometry may be useful tools for evaluation. The natural course of this condition, especially of asymptomatic cases, is not well clarified. Some newly developed anti-acid or anti-inflammatory medicines are now under investigation. With regard to autoimmune gastritis, because of widespread medical examinations, diagnosis of asymptomatic cases has been increasing. Recently, its endoscopic characteristics have become clear and the natural history of these conditions is being elucidated. The Kyoto Classification of Gastritis has been reported to be useful not only for Helicobacter pylori diagnosis but also for identification of risks of gastric cancer. Its usefulness is now recognized in Asia and Europe.

Abstract
OBJECTIVES The Japan Endoscopy Database Project was initiated to develop the world's largest endoscopy data repository. This study describes the first phase of the colonoscopy project in Japan. METHODS Data were aggregated offline by integrating information from the endoscopy database software from January 2015 through March 2017. The study population included all patients who underwent colonoscopy at eight centers. RESULTS A total of 31,395 patients who underwent 38,497 colonoscopy procedures were registered. The majority of procedures were performed for screening (n = 14,156), followed by fecal immunochemical test positivity (n = 3960), abdominal symptoms (n = 3864), post-colorectal surgery surveillance (n = 3431), post-endoscopic treatment surveillance (n = 3757), thorough pre-treatment examination (n = 2822), and therapeutic purposes (n = 6507). In the screening group, advanced cancers, early cancers, and adenomas were diagnosed endoscopically in 2.1%, 1.3%, and 28.7% of cases, respectively, while in the fecal immunochemical test-positive group, they were diagnosed in 2.5%, 1.9%, and 41.6% of cases, respectively. The incidence of complications was 0.177% and 0.152% in the screening and fecal immunochemical test-positive groups, respectively. The therapeutic procedures included 1446 cold forceps polypectomy procedures, 4770 cold snare polypectomy procedures, 368 hot biopsies, 2998 hot snare polypectomy procedures, 9775 endoscopic or piecemeal endoscopic mucosal resections, and 1660 endoscopic submucosal dissections. A total of 173 procedure-related complications (0.82%) occurred in 21,017 therapeutic procedures performed in 15,744 patients. CONCLUSIONS The first phase of the Japan Endoscopy Database Project established the proportions of the diagnostic and therapeutic colonoscopy procedures, and complication rates in real-world settings.

Abstract
BACKGROUND Functional dyspepsia (FD) is a disorder that presents with chronic dyspepsia, which is not only very common but also highly affects quality of life of the patients. In Japan, FD became a disease name for national insurance in 2013, and has been gradually recognized, though still not satisfactory. Following the revision policy of Japanese Society of Gastroenterology (JSGE), the first version of FD guideline was revised this time. METHOD Like previously, the guideline was created by the GRADE (grading of recommendations assessment, development and evaluation) system, but this time, the questions were classified to background questions (BQs, 24 already clarified issues), future research questions (FRQs, 9 issues cannot be addressed with insufficient evidence), and 7 clinical questions that are mainly associated with treatment. RESULTS AND CONCLUSION These revised guidelines have two major features. The first is the new position of endoscopy in the flow of FD diagnosis. While endoscopy was required to all cases for diagnosis of FD, the revised guidelines specify the necessity of endoscopy only in cases where organic disease is suspected. The second feature is that the drug treatment options have been changed to reflect the latest evidence. The first-line treatment includes gastric acid-secretion inhibitors, acetylcholinesterase (AChE) inhibitors (acotiamide, a prokinetic agent), and Japanese herbal medicine (rikkunshito). The second-line treatment includes anxiolytics /antidepressant, prokinetics other than acotiamide (dopamine receptor antagonists, 5-HT4 receptor agonists), and Japanese herbal medicines other than rikkunshito. The patients not responding to these treatment regimens are regarded as refractory FD.
