Abstract
BackgroundRheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that causes not only joint pain but also bone destruction resulting in impairment of quality of life. Tumor necrosis factor inhibitors have improved prognosis of patients with rheumatoid arthritis dramatically, especially in combination with methotrexate, however, the optimal dose of the concomitant methotrexate is unclear.ObjectivesTo evaluate the efficacy and safety of adalimumab in combination with reduced dose of methotrexate in patients with early RA with inadequate response to methotrexate.MethodsThe MIRACLE study was a multinational, randomized, open-label study in patients with RA with inadequate response to methotrexate conducted in Asia. It compared low dose and high dose methotrexate upon starting adalimumab. Methotrexate-naive patients with RA with a disease duration of less than two years started methotrexate at 6 to 8 mg/week and increased it to the maximum tolerable dose by week 12. Patients who have not achieved remission according to simplified disease activity index (SDAI) despite methotrexate ≥ 10 mg/week at week 24 were randomised to the maximum tolerable dose of methotrexate group (10 to 25 mg/week) or the reduced dose group (6 to 8 mg/week) and started to receive subcutaneous adalimumab 40 mg every other week. The primary endpoint was non-inferiority in the achievement of SDAI remission at week 48 in the reduced dose group compared with the maximum tolerable dose group with a non-inferiority margin of -15% based on two-sided 90% confidence interval. (NCT03505008)ResultsA total of 300 patients were enrolled in the study. Among them, 291 started methotrexate and were included in the analysis. The mean age was 57.7±15.2 years, female was 74.6%, and the mean disease duration from the diagnosis of RA was 21.1±56.2 days. Anti-CCP antibody was positive in 211 (73.0%) and the mean SDAI at study enrollment was 26.5±12.4. At week 24, with the mean dose of methotrexate of 12.6±2.9 mg/week, 108 patients (37.1%) achieved remission according to SDAI and continued MTX monotherapy. 134 patients (46.0%) were randomised and started adalimumab with 68 patients in the maximum tolerable dose group and 66 patients in the reduced dose group. At week 48, the remission achievement rates were 38.4 % and 44.8 %, respectively, with the adjusted risk difference of the reduced dose group to the maximum tolerable dose group of 6.4% (-7.0% to 19.8%, 90% CI), which met the criterion for noninferiority. No significant difference was found in health assessment questionnaire disability index ≤0.5 (59.1% vs 62.0%, respectively, p=0.72) and in radiological remission rates (Δmodified total Sharp score ≤0.5, 66.3% vs 62.0 %, respectively, p=0.59). Adverse drug reactions tended to be more frequent in the maximum tolerable dose group than in the reduced dose group (22.1% vs 9.1%, respectively, p=0.06).ConclusionThe MIRACLE randomised study demonstrated that, in patients with inadequate response to methotrexate, the efficacy of adalimumab with reduced dose of concomitant methotrexate was not inferior to that with maximum tolerable dose of methotrexate with better safety profile.Disclosure of InterestsHiroya Tamai Speakers bureau: Eisai, Grant/research support from: Eisai, Kei Ikeda Speakers bureau: AbbVie, Eisai, Eli Lilly, Novartis, Gilead, Asahi-Kasei, Grant/research support from: Mitsubishi-Tanabe, Toshiaki Miyamoto: None declared, Hiroaki Taguchi: None declared, Chang-Fu Kuo: None declared, Kichul Shin: None declared, Shintaro Hirata Speakers bureau: AbbVie, Asahi-Kasei, Astellas, Ayumi, Bristol Myers Squibb, Celgene, Chugai, Eisai, Eli Lilly, Gilead, Glaxo SmithKline, Janssen, Kyorin, Novartis, Pfizer, Sanofi, Tanabe-Mitsubishi, UCB, Paid instructor for: AbbVie, Mitsubishi-Tanabe, Consultant of: AbbVie, Astellas, Bristol Myers Squibb, Eisai, Gilead, Ily Lilly, Grant/research support from: AbbVie, Asahi-Kasei, Eisai, Otsuka, Sanofi, Shionogi, Chugai, Pfizer, Tanabe-Mitsubishi, Eli Lilly, UCB, yutaka okano: None declared, Shinji Sato Speakers bureau: AbbVie, Eisai, Grant/research support from: AbbVie, Eisai, Hidekata Yasuoka Speakers bureau: AbbVie, Asahi Kasei Pharma, Astellas, Daiichi-Sankyo, Eisai, Kissei, Takeda, Mitsubishi-Tanabe, Chugai, Novartis, Eli Lilly, Pfizer, Janssen, Sanofi, Teijin, Boehringer-Ingelheim, Bayer, Glaxo Smith Kline, Paid instructor for: AbbVie, Consultant of: AbbVie, Asahi Kasei, Grant/research support from: Mitsubishi-Tanabe, Takeda, Daiichi-Sankyo, Chugai, Bristol-Myers, MSD, Astellas, In Ah Choi Speakers bureau: Abbvie, Eisai, Sung-Hwan Park: None declared, Meng-Yu Weng Paid instructor for: Novartis, Eli Lilly, ChuGai, Abbvie, Consultant of: Abbvie, Masataka Kuwana Speakers bureau: Astellas, Asahi Kasei Pharma, Boehringer-Ingelheim, Chugai, Eisai, Janssen, Mochida, Nippon Shinyaku, Ono Pharmaceuticals, Pfizer, Mitsubishi-Tanabe, Consultant of: Boehringer-Ingelheim, Kissei, Mochida, Grant/research support from: AbbVie, Asahi Kasei Pharma, Boehringer-Ingelheim, Chugai, Eisai, MBL, Nippon Shinyaku, Ono Pharmaceuticals, Mitsubishi-Tanabe, Yun Jong Lee Grant/research support from: Yuhan, Tomonori Ishii Speakers bureau: Chugai, Mitsubishi-Tanabe, Glaxo Smith Kline, Pfizer, Eli Lilly, Janssen, AbbVie, Eisai, Astellas, Jinhyun Kim: None declared, Hideto Kameda Speakers bureau: AbbVie, Pfizer, Consultant of: AbbVie, Grant/research support from: AbbVie, Eisai, Toshihisa Kojima Speakers bureau: AbbVie, Pfizer, Eisai, Grant/research support from: AbbVie, Han Joo Baek: None declared, Ping-Ning Hsu: None declared, Chun-Ming Huang Paid instructor for: Abbvie, Pfizer, Tien-Tsai Cheng Paid instructor for: Abbvie, Grant/research support from: Abbvie, Wan-Yu Sung: None declared, Takehiro Taninaga Shareholder of: Eisai.co.,Ltd., Employee of: Eisai.co.,Ltd., Masahiko Mori Shareholder of: Eisai.co.,Ltd., Employee of: Eisai.co.,Ltd., Hideaki Miyagishi Shareholder of: Eisai.co.,Ltd., Employee of: Eisai.co.,Ltd., Yasunori Sato Speakers bureau: Eisai Co., Ltd.

Abstract
We sought to elucidate factors contributing to the grip strength (GS) decline in patients with gastrointestinal diseases (Ga-Ds, n = 602, 379 males, median age = 72 years). The GS decline in males and females was defined as <28 kg and <18 kg, respectively, following the current Asian guidelines. The median GS (male) was 28.8 kg, and GS decline (male) was found in 169 patients (44.6%). The median GS (female) was 17.5 kg, and GS decline (female) was found in 122 patients (54.7%). Advanced cancer was identified in 145 patients (24.1%). In terms of the univariate analysis of parameters of the GS decline, age (p < 0.0001), gender (p = 0.0181), body mass index (BMI, p = 0.0002), ECOG-PS (p < 0.0001), SARC-F score (p < 0.0001), hemoglobin value (p < 0.0001), total lymphocyte count (p < 0.0001), serum albumin value (p < 0.0001), C reactive protein (CRP) value (p < 0.0001), and estimated glomerular filtration rate were statistically significant. In terms of the multivariate analysis, age (p < 0.0001), BMI (p = 0.0223), hemoglobin value (p = 0.0186), serum albumin value (p = 0.0284), the SARC-F score (p = 0.0003), and CRP value (p < 0.0001) were independent parameters. In conclusion, the GS decline in patients with Ga-Ds is closely associated with not only the primary factor (i.e., aging) but also secondary factors such as inflammatory factors and nutritional factors.

Abstract
Simple Summary There have been few reports with regard to the relevance between the SARC-F score and the prognosis in patients with gastrointestinal advanced cancers, and we aimed to elucidate these issues (n = 421, median age = 73 years). During the follow-up period, 145 patients (34.4%) died. The 1-year cumulative overall survival rate in patients with SARC-F ≥ 4 (recommended cutoff point, n = 103) and SARC-F < 4 (n = 318) was 33.9% and 61.6% (p < 0.0001). In the multivariate analysis for the overall survival, total lymphocyte count ≥ 1081/μL (p = 0.0014), the SARC-F score ≥ 4 (p = 0.0096), Glasgow prognostic score 1 (p = 0.0147) and 2 (p < 0.0001), ECOG-PS 2 (p < 0.0001), and 3 (p < 0.0001) and 4 (p < 0.0001) were independent predictors. In the receiver operating characteristic curve analysis on the prognostic value of the SARC-F score, the sensitivity/specificity was 0.59/0.70, and the best cutoff point of the SARC-F score was two. The SARC-F score appears to be useful in patients with gastrointestinal advanced malignancies. Abstract We sought to elucidate the prognostic impact of the SARC-F score among patients with gastrointestinal advanced malignancies (n = 421). A SARC-F score ≥ 4 was judged to have a strong suspicion for sarcopenia. In patients with ECOG-PS 4 (n = 43), 3 (n = 61), and 0–2 (n = 317), 42 (97.7%), 53 (86.9%) and 8 (2.5%) had the SARC-F score ≥ 4. During the follow-up period, 145 patients (34.4%) died. All deaths were cancer-related. The 1-year cumulative overall survival (OS) rate in patients with SARC-F ≥ 4 (n = 103) and SARC-F < 4 (n = 318) was 33.9% and 61.6% (p < 0.0001). In the multivariate analysis for the OS, total lymphocyte count ≥ 1081/μL (p = 0.0014), the SARC-F score ≥ 4 (p = 0.0096), Glasgow prognostic score (GPS) 1 (p = 0.0147, GPS 0 as a standard), GPS 2 (p < 0.0001, GPS 0 as a standard), ECOG-PS 2 (p < 0.0001, ECOG-PS 0 as a standard), ECOG-PS 3 (p < 0.0001, ECOG-PS 0 as a standard), and ECOG-PS 4 (p < 0.0001, ECOG-PS 0 as a standard) were independent predictors. In the receiver operating characteristic curve analysis on the prognostic value of the SARC-F score, the sensitivity/specificity was 0.59/0.70, and best cutoff point of the SARC-F score was two. In conclusion, the SARC-F score is useful in patients with gastrointestinal advanced malignancies.

Abstract
Background:Methotrexate (MTX) is the first-line therapy for rheumatoid arthritis (RA). The concentrations of MTX-polyglutamates (PG) in erythrocytes, an active form of MTX, are useful markers for the optimal usage of MTX in patients with RA. The concentrations of MTX-PG have been reported to be different between Japanese and Caucasians. However, the difference among Asian ethnicity remains unclear.Objectives:To examine MTX-PG concentrations in association with MTX dose during the first 24 weeks after the initiation of MTX for newly diagnosed RA patients in Japan, Korea and Taiwan.Methods:MIRACLE study is a multicenter, open-label, randomized, 48 weeks interventional study conducted in Japan, Korea and Taiwan to evaluate non-inferiority of low dose to high dose of MTX as an add-on therapy to adalimumab in 300 patients with RA who do not achieve remission after 24 weeks MTX monotherapy in stipulated dosage. In the first 24 weeks, MTX was started at 6 to 8 mg/week for newly diagnosed RA patients, and promptly escalated to the maximum tolerable dose in 12 weeks in principle. This interim data evaluation was intended to investigate the differences among countries in the relationship between MTX dose, safety and MTX-PG concentrations in erythrocytes during the first 24 weeks. The efficacy of the treatment is not included at this point.Results:A total of 166 patients (106 in Japan, 35 in Korea, 25 in Taiwan) were included in this interim data. The age at treatment initiation was 57.2 years old on average and female was 79.5%. The time course changes in total and individual MTX-PG levels differed in the three countries. At 24 weeks, whereas the mean total MTX-PG concentrations were comparable (112.9 nmol/L in Japan, 104.4 nmol/L in Korea, and 115.7 nmol/L in Taiwan) with a dose of MTX of 12.3 mg/week, 14.1 mg/week, and 12.2 mg/week, respectively, the individual MTX-PG concentrations were different. The MTX-PG1 and MTX-PG2 concentrations were lower in Korea than Japan and Taiwan whereas MTX-PG3, MTX-PG4 and MTX-PG5 concentrations were the highest in Korea.Conclusion:The distribution of short-chain and long-chain MTX-PG concentrations were various among Asian countries despite similar dose of MTX administration: NCT03505008.Disclosure of Interests:Hiroya Tamai: None declared, Yuko Kaneko Speakers bureau: AbbVie, Astellas, Ayumi, Bristol–Myers Squibb, Chugai, Eisai, Eli Lilly, Hisamitsu, Jansen, Kissei, Kirin, Pfizer, Sanofi, Takeda, Tanabe-Mitsubishi, and UCB., Grant/research support from: Sanofi, Hideto Kameda Speakers bureau: AbbVie, Pfizer, Consultant of: AbbVie, Grant/research support from: AbbVie, Eisai, Masataka Kuwana Speakers bureau: Astellas, Asahi Kasei Pharma, Boehringer- Ingelheim, Chugai, Eisai, Janssen, Mochida, Nippon Shinyaku, Ono Pharmaceuticals, Pfizer, Mitsubishi-Tanabe, Consultant of: Corbus, Grant/research support from: AbbVie, Asahi Kasei Pharma, Boehringer- Ingelheim, Chugai, Eisai, MBL, Nippon Shinyaku, Ono Pharmaceuticals, Mitsubishi-Tanabe, Yutaka Okano: None declared, Tomonori Ishii Speakers bureau: Chugai, Mitsubishi- Tanabe, Glaxo Smith Kline, Pfizer, Eli Lilly, Janssen, AbbVie, Eisai, Astellas, Kei Ikeda Speakers bureau: AbbVie, Eli Lilly, Novartis, Mitsubishi-Tanabe, Eisai, BMS, Grant/research support from: Mitsubishi-Tanabe, Hiroaki Taguchi: None declared, Shinji Sato: None declared, Toshiaki Miyamoto: None declared, Shintaro Hirata Speakers bureau: AbbVie, Asahi Kasei Pharma, Astellas, Ayumi, Bristol Myers Squibb, Chugai, Eisai, Eli Lilly, Janssen, Glaxo Smith Kline, Kissei, Pfizer, Sanofi, Mitsubishi- Tanabe, UCB, Paid instructor for: AbbVie, Mitsubishi- Tanabe, Consultant of: AbbVie, Eisai, Gilead, Grant/research support from: AbbVie, Chugai, Mitsubishi-Tanabe, UCB, Hidekata Yasuoka Speakers bureau: AbbVie, Asahi Kasei Pharma, Astellas, Daiichi- Sankyo, Eisai, Kissei, Takeda, Mitsubishi- Tanabe, Chugai, Novartis, Eli Lilly, Pfizer, Janssen, Sanofi, Teijin, Boehringer- Ingelheim, Bayer, Glaxo Smith Kline, Paid instructor for: AbbVie, Consultant of: AbbVie, Asahi Kasei, Grant/research support from: Mitsubishi-Tanabe, Takeda, Daiichi-Sankyo, Chugai, Bristol-Myers, MSD, Astellas, Toshihisa Kojima Speakers bureau: AbbVie, Pfizer, Eisai, Grant/research support from: AbbVie, Sung-Hwan Park: None declared, Kichul Shin: None declared, Han Joo Baek: None declared, Yun Jong Lee Grant/research support from: research fund, In Ah Choi Speakers bureau: Abbvie, Eizai, Grant/research support from: Abbvie, Eizai, Jinhyun Kim: None declared, Ping-Ning Hsu: None declared, Chang-Fu Kuo: None declared, Chun-Ming Huang Paid instructor for: AbbVie, Pfizer, Meng-Yu Weng Consultant of: AbbVie, Wan-Yu Sung: None declared, Wen-Chan Tsai: None declared, Tien-Tsai Cheng Paid instructor for: AbbVie, Grant/research support from: AbbVie, Takehiro Taninaga Shareholder of: Eisai Co., Ltd., Employee of: Eisai Co., Ltd., Masahiko Mori Shareholder of: Eisai Co., Ltd., Employee of: Eisai Co., Ltd., Hideaki Miyagishi Employee of: Eisai Co., Ltd., Yasunori Sato: None declared, Tsutomu Takeuchi Speakers bureau: Astellas, Abbvie, Daiichi Sankyo, Ayumi, Eisai, GlaxoSmithKline, Mitsubishi Tanabe, Chugai, Novartis, Eli Lilly, Pfizer, Bristol Myers Squibb, Janssen, UCB, TaishoToyama, Sanofi–Aventis, Nipponkayaku, Taiho, Gilead, Boehringer Ingelheim, Grant/research support from: Asahikasei, Astellas, Abbvie, Daiichi Sankyo, Ayumi, Eisai, Takeda, Mitsubishi Tanabe, Chugai, Eli Lilly, UCB, Sanofi–Aventis, Nipponkayaku, Boehringer Ingelheim

Abstract
Many people were forced to stay at home, including non-alcoholic steatohepatitis (NASH) patients, however it is unclear how this home-life has affected the prognosis of NASH. In this study, we examined the influences of living at home during the coronavirus disease 2019 (COVID-19) pandemic NASH patients. In this study, we compared the clinical parameters of NASH patients without COVID-19 infection 3 months before with those 3 months after the declaration of a state of emergency. In the results, the changes of aspartate transaminase and alanine aminotransferase in the 3 months before (aspartate transaminase, -3.6 ± 13.8 U/L; alanine aminotransferase, -6.8 ± 19.5 U/L) was significantly exacerbated in the 3 months after (aspartate transaminase, 2.3 ± 7.5 U/L; alanine aminotransferase, 1.7 ± 10.4 U/L). Furthermore, the changes of the fibrosis-4 index in the 3 months before (-0.27 ± 0.84) was also significantly exacerbated in the 3 months after (0.38 ± 0.96). In conclusion, liver dysfunctions in NASH patients were exacerbated due to the emergency declaration and outing restriction which accompanied COVID-19.

Abstract
Background Although the 2018 revised International Society of Nephrology/Renal Pathology Society (ISN/RPS) classification was proposed recently, until now, no reports have been made comparing the association of renal prognosis between the 2018 revised ISN/RPS classification and the 2003 ISN/RPS classification. The present study aimed to assess the usefulness, especially of activity and chronicity assessment, of the 2018 revised ISN/RPS classification for lupus nephritis (LN) in terms of renal prognosis compared to the classification in 2003. Methods We retrospectively collected medical records of 170 LN patients from the database of renal biopsy at Fujita Health University from January 2003 to April 2019. Each renal biopsy specimen was reevaluated according to both the 2003 ISN/RPS classification and the 2018 revised ISN/RPS classification. Renal endpoint was defined as a 30% decline of estimated glomerular filtration rate (eGFR). Results A total of 129 patients were class III/IV±V (class III, 44 patients; class IV, 35 patients; class III/IV+V, 50 patients). The mean age was 42 years, 88% were female, and the median observation period was 50.5 months. Renal prognosis was significantly different among the classes and significantly poor in the patients with higher modified National Institute of Health (mNIH) chronicity index (C index, ≥ 4) by a log-rank test (p = 0.05 and p = 0.02, respectively). By Cox proportional hazard models, only the C index was significantly associated with renal outcome (hazard ratio 1.32, 95% CI 1.11–1.56, p ≤ 0.01), while the classes, the 2003 activity and chronicity subdivision, and the mNIH activity index had no significant association with renal outcome. Each component of the C index was significantly associated with renal outcome in different models. Conclusion This study demonstrates that the 2018 revised ISN/RPS classification was more useful in terms of association with renal prognosis compared to the 2003 ISN/RPS classification.

Abstract
Immune-related adverse events (irAEs) are induced by immune checkpoint inhibitors (ICIs). Liver is one of the main target organs which irAEs occur and we investigated the influence of liver dysfunction on prognosis of patients after ICIs. From July 2014 to December 2018, 188 patients with diverse cancers who received ICIs (nivolumab or pembrolizumab) were enrolled. Twenty-nine patients experienced liver dysfunction of any grades after ICIs. Progression-free survival (PFS) was significantly shorter in the liver dysfunction-positive group than in the liver dysfunction-negative group, and a similar result was obtained for Overall survival (OS). Multiple logistic regression analysis revealed liver metastasis and alanine aminotransferase before ICIs were associated with a higher incidence of liver dysfunction after ICIs. Regardless of liver metastasis, PFS and OS were significantly shorter in the liver dysfunction-positive group. In conclusion, this study suggests liver dysfunction is associated with poor prognosis in patients after ICIs with diverse cancers.

Abstract
Monocytes (CD14+ cells) from advanced-stage hepatocellular carcinoma (HCC) patients express programmed death 1 ligand (PD-L)/PD-1 and suppress the host antitumor immune response. However, it is unclear whether cancer progression is associated with CD14+ cells. We compared CD14+ cell properties before and after cancer progression in the same HCC patients and examined their role in antitumor immunity. CD14+ cells were isolated from 15 naïve early-stage HCC patients before treatment initiation and after cancer progression to advanced stages. Although CD14+ cells from patients at early HCC stages exhibited antitumor activity in humanized murine chimera, CD14+ cells from the same patients after progression to advanced stages lacked this activity. Moreover, CD14+ cells from early HCC stages scantly expressed PD-L1 and PD-L2 and produced few cytokines, while CD14+ cells from advanced stages showed increased PD-L expression and produced IL-10 and CCL1. CD14+ cells were also isolated from five naïve advanced-stage HCC patients before treatment as well as after treatment-induced tumor regression. The CD14+ cells from patients with advanced-stage HCC expressed PD-L expressions, produced IL-10 and CCL1, and exhibited minimal tumoricidal activity. After treatment-induced tumor regression, CD14+ cells from the same patients did not express PD-Ls, failed to produce cytokines, and recovered tumoricidal activity. These results indicate that PD-L expression as well as CD14+ cell phenotype depend on the tumor stage in HCC patients. PD-L expressions of monocytes may be used as a new marker in the classification of cancer progression in HCC.

Abstract
Background:Anti-melanoma differentiation-associated gene 5 antibody (anti-MDA5 Ab)-positive dermatomyositis (DM) is frequently associated with rapidly progressive interstitial pneumonia (RPIP), whose prognosis is assumed to be poor[1]. Although outcome of DM-RPIP has been reported to be improved by early immunosuppressive therapy, we still experience the cases with severe outcome. Only several reports mentioned the prognostic factors and they have not been fully elucidated.Objectives:To identify the predictors of prognosis in patients with anti-MDA5 Ab-positive DM associated with interstitial pneumonia (DM-IP).Methods:Anti-MDA5 Ab-positive DM-IP patients admitted to Fujita Health University Hospital between January 2010 and October 2019 were consecutively included and stratified into 2 groups, the survived and the deceased groups. DM was diagnosed according to the criteria proposed by Bohan and Peter[2]. Clinically amyopathic DM was diagnosed according to the criteria proposed by Sontheimer [3]. Diagnosis of IP was based on findings of high resolution CT scan (HRCT). The definition of RPIP was rapid exacerbation of hypoxemia or HRCT findings in a period of days to one month after the onset. Clinical features and prognosis of the patients were collected retrospectively and compared between groups. Candidates of predictors are extracted by the univariable analysis using Fisher’s exact test for dichotic parameters and Wilcoxon signed-rank test for continuous parameters and multivariable analysis using logistic regression analysis. Receiver operating characteristic (ROC) curve analysis was examined to obtain the cut-off level. Survival was examined using Kaplan-Meier method and Log-rank test.Results:Twenty-one patients were involved. Eight were deceased and 13 were survived. The deceased group had a higher ratio of male (75% versus 25%, p= 0.018). All deceased cases were with RPIP and 67 % in the survived cases. Levels of serum ferritin (4490 versus 646 ng/mL, p = 0.0026), CRP (2.1 versus 0.9 mg/dL, p = 0.0490), CK (1150 versus 290 U/L, p = 0.017), AST (194 versus 108 U/L, p = 0.025) and LDH (674 versus 368 U/L, p = 0.011) were higher in the deceased group. Interestingly, skin ulcers were tended to be more frequent (12.5% versus 87.5%, p= 0.0587), and anti-SS-A antibody was also more frequently detected (14.3% versus 85.7%, p=0.0072) in the survived group. Using ROC analysis cut-off values were 963 ng/mL for serum ferritin level (sensitivity 100%, specificity 83%), 0.7 mg/dL for CRP (sensitivity 75%, specificity 69%), 308 U/L for CK (sensitivity 88%, specificity 77%), 62 U/L for ALT (sensitivity 100%, specificity 62%), and 454 U/L for LDH (sensitivity 88%, specificity 77%). Patients were divided into two groups based on these cut-offs or based on dichotic parameters and survival was examined between 2 groups. Except CRP and anti-SS-A antibody, survival was significantly worse in parameter-positive or higher groups. Interestingly, anti-SS-A antibody-positive group had better outcome compared with those without.Conclusion:In our analysis, novel candidates such as serum CK, AST, and LDH levels were newly extracted and parameters previously reported was also included and those were also associated with the clinical outcome. In addition, anti-SS-A antibody was identified as a novel protective factor associated with a good outcome.References:[1]Nakashima R, Hosono Y, Mimori T.

Abstract
Abstract
The prognosis of patients with hepatocellular carcinoma (HCC) is poor. Anti–programmed death-1 (PD-1) antibodies (Abs) has been approved to treat HCC. Some PD-1 ligands (PD-L1 and PD-L2) negative tumors respond to anti–PD-1 Abs. This response may be caused by the expression of PD-1 ligands on non-tumor cells. PD-1 ligands were recently found to be expressed on monocytes (CD14+ cells) from diverse cancer patients. In this study, we investigate the expression of PD-1 ligands on CD14+ cells from HCC patients and the role of CD14+ cells in an antitumor response.
From October 2017 to June 2019, 67 patients with HCC were enrolled. The expression of PD-L1 and PD-L2 on CD14+ cells was analyzed by flow cytometry. Their prognosis was evaluated by overall survival (OS). Tumoricidal activities of both CD14+ and CD8+ cells were calculated by LDH release assay.
In the results, CD14+ cells from the patients expressed PD-L1 (4.5–95.5%) and PD-L2 (1.6–90.2%). We set cut-off values as the mean values of PD-L1 (50.2%) and PD-L2 (50.5%) expression. In addition, according to the cut-off value, we classified patients as those either with PD-L1+PD-L2+CD14+ cells or other types of CD14+ cells. The OS of patients with PD-L1+PD-L2+CD14+ cells was significantly shorter than that of patients with other types of CD14+ cells (p = 0.0145). The tumoricidal activity of CD8+ cells from patients with PD-L1+PD-L2+CD14+ cells was suppressed by co-cultivation with syngeneic CD14+ cells. Furthermore, anti–PD-1 Ab restored the tumoricidal activity of CD8+ cells.
In conclusions, some patients with HCC have PD-L1+PD-L2+CD14+ cells that suppress their antitumor response of CD8+ cells. These inhibitory functions of CD14+ cells may be associated with a poor prognosis in such patients.

Abstract
M2b macrophages (Mf)/monocytes play a role in the increased susceptibility of alcoholics to infections. However, the mechanism involved in M2bMf polarization remains unclear. In this study, we investigated the role of CD34+CD10+CD19−Pax5+ cells (Pre/Pro-B cells) in the peripheral blood of alcoholics on alcohol-related M2bMf/monocyte polarization through the production of high mobility group box-1 (HMGB1). M2b monocytes were identified as few bactericidal activity, IL-10 and CCL1 productions. Pre/Pro-B cells isolated from 18 alcoholics and 11 healthy donors (HD) were cultured with 10 nM of retinoic acid for 24hrs and culture medium obtained were assayed for HMGB1 by ELISA. CD14+cells (1 × 106 cells/ml) from HD were stimulated with 10% (v/v) of each culture media of Pre/Pro-B cells for 24hrs and their producing abilities of IL-10 and CCL1 were assayed. And 1 × 106 cells/ml of these cells were infected with 2 × 106 CFU /ml Enterococcus faecalis (E. faecalis). The bactericidal activity was assayed for colony counting methods. In the results, Pre/Pro-B cells from HD did not produce HMGB1(10.5 ± 5.5 ng/mL), while these cells from alcoholics did (70.3 ± 20.2 ng/mL). When CD14+ cells from HD were stimulated with each culture media from alcoholics, these CD14+ cells produced IL-10 (102.3 ± 1.7 pg/mL) and CCL1 (3.12 ± 1.33 ng/mL) and did not have bactericidal activity against E. faecalis (17.0 ± 8.6%). However, same CD14+ cells from HD were stimulated with each culture media from HD, these cells did not produce IL-10 (10.3 ± 3.4 pg/mL) and CCL1 (0.3 ± 0.01 ng/mL) and have the bactericidal activity (62.8 ± 3.8%). These results indicate that Pre/Pro-B cells play a crucial role in M2bMf/monocyte polarization via HMGB1 production in alcoholics.

Abstract
Two hepatic macrophage (MΦ) populations have been described in the inflamed liver: F4/80+CD11b+ cells and F4/80+CD68+ cells. In normal conditions, hepatic F4/80+CD11b+ cells are involved in host antibacterial resistance. However, these cells in total body irradiated mice (TBI mice) are unfunctional for the elimination of bacteria translocated from intestinal tracts. In this study, the properties of hepatic MΦ populations in TBI mice were characterized. Normal mice and mice 7 days after exposure to 4 Gy of X-rays were infected i.v. with 107 CFU/mouse of Enterococcus faecalis (E. faecalis). Three day after infection, F4/80+CD11b+ cells and F4/80+CD68+ cells isolated from the liver of these mice were cultured for 24 hrs, and culture fluids were assayed for IL-12, IL-10 and CCL1 by ELISA. NSG mice were inoculated i.v. with these MΦ preparations (2 × 105 cells/mouse), then infected i.v. with 5 × 104 CFU/mouse of E. faecalis. In the results, all TBI mice died within 2 weeks, while all normal mice survived. IL-12 was produced by F4/80+CD11b+ cells from normal mice, but not by both MΦ preparations from TBI mice. IL-10 was produced by F4/80+CD68+ cells from TBI mice (529.9 ± 272.6 pg/ml) and normal mice (445.8 ± 147.7 pg/ml). Large amounts of IL-10 (912.1 ± 103.7 pg/ml) was produced by F4/80+CD11b+ cells from TBI mice, and these cells produced CCL1 (327.5 ± 9.1 pg/ml), while other MΦ preparations did not. NSG mice inoculated with F4/80+CD11b+ cells from normal mice were resistant to infection; however, NSG mice inoculated with F4/80+CD11b+ cells from TBI mice did not. These results indicate hepatic F4/80+CD11b+ cells are polarized to M2bMΦ in response to total body irradiation, and these MΦ are involved in the decreased host antibacterial resistance in TBI mice.

Abstract
Hepatocellular carcinoma (HCC) is the fifth common cancer in the world. In previous study, we reported that M2b monocytes which predominately generated in advanced-stage HCC patients were important target for HCC immunotherapy. Recently, an anti-PD-1 antibody has been approved for the treatment against HCC. In this study, we tried to analyzed for immunological characters of monocytes isolated from patients with several stages of HCC.
From 2017 August to 2017 December, nine patients diagnosed as advanced-stage HCC patients and five patients diagnosed as early-stage HCC patients were enrolled in this study. Monocytes from peripheral blood of these patients were stained for anti-PD-1 antibody, anti-PD-L1 antibody and anti-PD-L2 antibody. These cells were analyzed for flow cytometry. Furthermore, five healthy donors were used for the control groups.
In the results, a majority of monocytes from advanced-stage HCC patients were expressed PD-L1 (81.5 ± 14.7%) and PD-L2 (71.6 ± 18.5%), but not PD-1(20.2 ± 18.6%). And, monocytes from early-stage HCC patients were expressed PD-L1 (9.9 ± 4.1%), PD-L2 (38.74 ± 9.9%) and PD-1 (23.5 ± 9.8%). As the contorls, monocytes from healthy donors were not expressed PD-L1 (21.7 ± 5.5%), PD-L2 (31.7 ± 23.8%) and PD-1 (11.6 ± 6.4%). The PD-L1 expression in monocytes was increased as HCC progressed.
These results indicate the PD-L1 expression may be used as a new marker for the classification of the cancer progression. And, PD-1−PD-L1+PD-L2+ monocytes which were predominantly generated in advanced-stage HCC patients, may target for the treatment of anti-PD-L1 antibody.

Abstract
A 37-year-old woman was diagnosed with chronic phase chronic myeloid leukemia. Nilotinib treatment was initiated; however, it had to be discontinued due to an allergic reaction one month later, and dasatinib treatment was provided. Although favorable response was obtained, she started complaining of shortness of breath 7 months after initiating dasatinib treatment. Chest X-ray and echocardiography indicated pulmonary congestion and hypertension. Further, she was diagnosed with mixed connective tissue disease (MCTD) based on Raynaud phenomenon, swollen fingers, sclerodactyly, pancytopenia, hypocomplementemia, and positive anti-U1-RNP antibody. Consequently, dasatinib treatment was discontinued, and she was administered prednisolone (1 mg/kg/day), which was effective and successfully tapered with concomitant administration of cyclophosphamide. This is the first case of MCTD that developed during dasatinib treatment. However, because the present case was a young woman, the development of MCTD could probably be attributed to autoimmune diatheses or it may be a coincidence. However, the possibility of patients receiving dasatinib treatment developing autoimmune diseases needs to be assessed.

Abstract
Transarterial chemoembolization and hepatic arterial infusion chemotherapy are recommended for the treatment in patients with intermediate stage of hepatocellular carcinoma. Impaired liver function was sometime observed in patients with hepatocellular carcinoma after transarterial chemoembolization or hepatic arterial infusion chemotherapy. However, what kinds of factors deeply influence in impaired liver function are not clear. A retrospective study was performed to evaluate the risk factors of impaired liver function in cisplatin-naïve patients treated with these therapies using cisplatin. Prior to and 2 months after these therapies, we analyzed the liver function by Child-Pugh score in these patients. For assessing the severity of chemotherapy-induced nausea and vomiting, we utilized the Common Terminology Criteria for Adverse Events ver. 4.0. In hepatocellular carcinoma patients received these therapies using cisplatin, the cancer stage and treatment without neurokinin-1 (NK1) antagonist were found to be independent risk factors of the impaired liver function. The treatment with NK1 antagonist was effective in reducing chemotherapy-induced nausea and vomiting and patients treated with NK1 antagonist kept their liver functions after cisplatin-used these therapies. The treatment with NK1 antagonist was effective in chemotherapy-induced nausea and vomiting and prevented the impaired liver function associated with cisplatin-used these therapies in hepatocellular carcinoma patients.

Abstract
AUD patients have an increased risk of serious opportunistic infections. IMCs have been described as suppressor cells for host antibacterial defenses. In this study, IMCs isolated from AUD patients were examined for their inhibitory functions on the bactericidal activity of healthy donor (HD) monocytes. IMCs and monocytes were isolated from the peripheral blood of 10 AUD patients admitted to Osaka Medical Collage and 5 HD. HD monocytes (1 × 105 cells/ml) were stimulated with heat-killed Enterococcus faecalis, then cultured in media supplemented with the conditioned media of patient IMCs (24 hr-culture fluids, 10% v/v, 1 × 106 cells/ml). Twenty-four hrs after the cultivation, monocytes were harvested and tested for their bactericidal activities against E. faecalis. In some cases, patient IMCs, cultured with 5 μg/ml of retinoic acid (RA) for 24 hrs, were utilized for the experiments. Also, both groups of IMCs were analyzed for RA receptor (RAR) expression by flow cytometry. In the results, as compared to HD peripheral blood IMCs, the numbers of IMCs increased in AUD patients. HD monocytes were shown to be bactericidal against E. faecalis. However, the bactericidal activity of HD monocytes was not demonstrated when they were cultured with media supplemented with the conditioned media of patient IMCs. HD IMCs differentiated to monocytes or dendritic cells after cultivation with RA. However, AUD patient IMCs were shown to be not susceptible to RA treatment (patient IMCs, RAR−; HD IMCs, RAR+). These results suggest that, through the production of some soluble factors active against killing functions of monocytes, patient IMCs increase the susceptibility of AUD patients to opportunistic infections.

Abstract
OBJECTIVES To evaluate the roles of circulating B cells in the pathogenic process of systemic lupus erythematosus (SLE) by measuring the expression of chemokines and their receptors. METHODS Peripheral-blood mononuclear cells were obtained from 17 active, 21 inactive SLE patients, and 13 healthy controls. The expression of CXCR4, CXCR5, and CCR7 on CD19+ B cells was determined by flow cytometry, serum concentration of CXCL12 was measured by enzyme-linked immunosorbent assay, and the chemotactic responsiveness of B cells toward CXCL12 was evaluated. B or plasma cells expressing CXCR4 in renal biopsy specimens were detected using immnofluorescent staining. RESULTS Flow cytometric analysis revealed that expression level of CXCR4 on circulating B cells was significantly higher in patients with active disease than in those with inactive disease or controls. Serum CXCL12 concentration was not different between these groups. In addition, the migratory ability of B cells toward CXCL12 was enhanced in active SLE patients. Finally, CXCR4-expressing B cells were more frequently observed in the renal biopsy specimens of lupus nephritis. CONCLUSIONS Up-regulated CXCR4 expression on circulating B cells in active SLE may enhance their chemotactic response toward CXCL12, which may promote infiltration of these cells into inflamed renal tissue and contribute to the development of SLE.

Abstract
Nuclear magnetic resonance (NMR) measurements on the ^{195}Pt nucleus in an aligned powder of the moderately heavy-fermion material U_{2}PtC_{2} are consistent with spin-triplet pairing in its superconducting state. Across the superconducting transition temperature and to much lower temperatures, the NMR Knight shift is temperature independent for field both parallel and perpendicular to the tetragonal c axis, expected for triplet equal-spin pairing superconductivity. The NMR spin-lattice relaxation rate 1/T_{1}, in the normal state, exhibits characteristics of ferromagnetic fluctuations, compatible with an enhanced Wilson ratio. In the superconducting state, 1/T_{1} follows a power law with temperature without a coherence peak giving additional support that U_{2}PtC_{2} is an unconventional superconductor. Bulk measurements of the ac susceptibility and resistivity indicate that the upper critical field exceeds the Pauli limiting field for spin-singlet pairing and is near the orbital limiting field, an additional indication for spin-triplet pairing.

Abstract
The results of (115)In nuclear quadrupole resonance (NQR) measurements on PuIn3 are reported. Three of the four NQR lines of (115)In expected for nuclear spin I = 9/2 are observed. The equal spacing of these lines at 20 K yields the NQR frequency of νQ = 10.45 MHz, and the asymmetry parameter of the electric field gradient η = 0. The NQR line profile and the nuclear spin-lattice relaxation rate 1/T1 display an abrupt change at 14 K, which is associated with the onset of long-range antiferromagnetic order. The temperature dependences of the staggered magnetization MQ(T), extracted from the NQR spectra, and 1/T1 below TN = 14 K are well explained by the self-consistent renormalization (SCR) theory for spin fluctuations. In addition, the scaling between T1T and MQ(T)/MQ(0) is also consistent with the predictions of SCR theory, providing further evidence that PuIn3 is a weak itinerant antiferromagnet in which spin fluctuations around the antiferromagnetic wavevector play a major role in the system's behavior at finite temperatures.

Abstract
Antibodies against double-stranded DNA (dsDNA) are widely used to diagnose systemic lupus erythematosus (SLE) and evaluate its activity in patients. This study was undertaken to examine the clinical utility of circulating anti-dsDNA antibody-secreting cells for evaluating SLE patients. Anti-dsDNA antibody-secreting cells quantified using an enzyme-linked immunospot assay were detected in the spleen, bone marrow and peripheral blood from MRL/ lpr but not in control BALB/c mice. Circulating anti-dsDNA antibody-secreting cells were detected in 29 (22%) of 130 patients with SLE, but in none of 49 with non-SLE connective-tissue disease or 18 healthy controls. The presence of circulating anti-dsDNA antibody-secreting cells was associated with persistent proteinuria, high SLE disease activity index and systemic lupus activity measures, and a high serum anti-dsDNA antibody titre measured with an enzyme-linked immunosorbent assay. The positive predictive value for active disease was 48% for circulating anti-dsDNA antibody-secreting cells versus 17% for serum anti-dsDNA antibodies. A prospective cohort of patients with circulating anti-dsDNA antibodies and inactive SLE showed that the cumulative disease flare-free rate was significantly lower in patients with than without circulating anti-dsDNA antibody-secreting cells ( p < 0.001). Circulating anti-dsDNA antibody-secreting cells are a useful biomarker for assessing disease activity in SLE patients.

Abstract
In principle, the spin-½ plutonium-239 ((239)Pu) nucleus should be active in nuclear magnetic resonance spectroscopy. However, its signal has eluded detection for the past 50 years. Here, we report observation of a (239)Pu resonance from a solid sample of plutonium dioxide (PuO(2)) subjected to a wide scan of external magnetic field values (3 to 8 tesla) at a temperature of 4 kelvin. By mapping the external field dependence of the measured resonance frequency, we determined the nuclear gyromagnetic ratio (239)γ(n)(PuO(2))/2π to be 2.856 ± 0.001 megahertz per tesla (MHz/T). Assuming a free-ion value for the Pu(4+) hyperfine coupling constant, we estimated a bare (239)γ(n)/2π value of ~2.29 MHz/T, corresponding to a nuclear magnetic moment of μ(n) ≈ 0.15μ(N) (where μ(N) is the nuclear magneton).

Abstract
OBJECTIVE To investigate whether single-nucleotide polymorphisms (SNPs) within the estrogen receptor (ER) alpha and Beta genes are associated with disease susceptibility and clinical presentation in Japanese patients with systemic sclerosis (SSc). METHODS Three SNPs, ERalpha PvuII T/C, ERalpha XbaI A/G, and ERBeta RsaI G/A, were genotyped using polymerase-chain reaction combined with restriction fragment length polymorphisms in 103 patients with SSc and 56 race-matched healthy controls. The distribution of the individual ER SNPs in SSc patients with or without SSc-related organ involvement and serum antinuclear antibodies was determined. RESULTS The frequency of the ERalpha XbaI GG phenotype was significantly lower in SSc patients than in healthy controls (2% vs. 13%, p=0.005, odds ratio=0.14, 95%CI 0.03-0.69), and no significant association was detected for the other SNPs. Except in the case of heart involvement accompanying SSc, there was no significant association of the ER SNPs with SSc-related individual organ involvement or with antinuclear antibody profiles. Specifically, the ERalpha PvuII CC phenotype was significantly more frequent among patients with heart involvement compared with those without it (75% vs. 14%, p=0.0001, odds ratio=17.4, 95%CI 3.2-94.8). CONCLUSION SNPs located within the ERalpha gene may contribute to disease susceptibility and to certain clinical manifestations of SSc patients.

Abstract
OBJECTIVE To evaluate the activation status of circulating CD4+, CD8+, and gammadelta T cells in patients with active and inactive Behçet's disease (BD). METHODS We studied 11 subjects with active BD, 28 with inactive BD, and 13 healthy controls. The expression of CD4, CD8, pan-gammadelta, Vdelta1, and Vdelta2 along with the early activation marker CD69 was analyzed by 3-color flow cytometry. RESULTS Proportions of activated CD8+ and gammadelta T cells were significantly greater in patients with active BD than in those with inactive BD or healthy control subjects, but the proportion of activated CD4+ T cells did not differ among these 3 groups. In addition, significantly greater proportions of the Vdelta1+ and Vdelta2+ gammadelta T-cell subsets were activated in patients with active BD than in those with inactive BD or healthy controls; in active BD, the balance of activation between these subsets favored the Vdelta1+ T cells. No significant differences in these proportions were found between subjects with inactive BD and healthy controls. These findings were observed exclusively in patients with HLA-B51. A comparison of samples from 5 patients taken during active BD and after resolution of BD-related symptoms showed the proportions of activated CD8+ and gammadelta T cells dropped when the patients' BD became inactive. CONCLUSION CD8+ and gammadelta T cells, rather than CD4+ T cells, were activated in vivo in patients with active BD and HLA-B51, but not in those with inactive BD, suggesting that these potentially cytotoxic T cells play a critical role in BD flares.

Abstract
AIMS To review differences in biological aggressiveness, clinical behaviors or selected surgical treatments between the PMC and the slightly larger PTC of 1.0<T<or=2.0 cm. METHODS Two hundred and twenty-seven cases of papillary thyroid carcinoma not larger than 2.0 cm, diagnosed and treated at the Kuma Hospital, Kobe, Japan, with a 10-year follow-up from 1992 to 2003, were reviewed. RESULTS The small PTCs demonstrated excellent outcomes, and persistent/recurrent disease was identified in only nine patients (4%). None of the patients died of the disease. A multivariate analysis revealed that massive extrathyroidal extension at presentation was the only independent prognostic factor for locoregional recurrence. Subdivision into PMCs and slightly larger tumors (1<T<or=2 cm) did not affect the excellent outcomes, but the patients in the latter subgroup received more lymph node surgery and displayed more aggressive clinico-histological features such as higher rates of extrathyroidal extension, lymph node metastasis, loss of polarity, invasive growth pattern and loss of cohesiveness. CONCLUSIONS Small PTC not larger than 2.0 cm could be considered as favorable a prognosis as PMC.

Abstract
We report a microscopic investigation of multipolar order parameters in the ordered state of NpO2 conducted via 17O NMR on a single crystal. From the angular dependence of hyperfine fields at 17O nuclei, we have obtained clear evidence for the appearance of field-induced antiferro-octupolar as well as field-induced antiferro-dipolar moments below T0 = 26 K. We have also observed oscillatory spin-echo decay, which is well understood in terms of small electric field gradients created by antiferro-quadrupolar ordering. This reveals that the quadrupolar order parameter is directly observable by means of NMR. The present NMR studies provide definitive support for a proposed longitudinal triple-q type octupolar-quadrupolar ordering model for NpO2.

Abstract
BACKGROUND Metastasis to regional lymph nodes (LNs) through lymphatic vessels is common in cancer progression and is an important prognostic factor in many cancers. Recent evidence suggests that tumour lymphangiogenesis promotes lymphatic metastasis. AIMS To study the role of lymph vessel density (LVD) in gastric cancer and investigate whether LVD is associated with LN metastasis/prognosis. METHODS Lymphatics of 117 primary human gastric cancer cases were investigated by quantitative immunohistochemical staining for podoplanin. The relation between LVD and LN metastasis and other established clinicopathological parameters was analysed. The relation between LVD and prognosis was also studied. RESULTS Mean LVD of "hot spots" was 11.6/case. LVD significantly correlated with LN and podoplanin positive lymphatic invasion. High LVD was associated with worse overall survival. In multivariate analysis, positive LVD was a significant independent predictor of overall survival, depth of invasion, and TNM stage. LVD significantly correlated with LN metastasis at surgery and podoplanin positive lymphatic invasion. In multivariate analysis, positive LVD was an independent significant predictor of LN metastasis. CONCLUSIONS Increased podoplanin expression is significantly associated with LN metastasis, and may play an important role in detecting LN metastasis in gastric cancer. Furthermore, LVD may be a significant prognostic factor in gastric cancer at any stage. In addition, LVD and lymph vessel invasion detected by podoplanin immunohistochemistry are associated with LN metastasis in T1 early gastric cancer. LVD assessment by podoplanin immunohistochemistry may become a useful predictor of LN metastasis in T1 early gastric cancer and may influence the decision making process for additional surgery.
