Abstract
OBJECTIVES To evaluate the additional diagnostic benefit of diffusion weighted imaging (DWI) and contrast enhanced (CE) images during MR enterography (MRE) of Crohn's disease. METHODS Datasets from 73 patients (mean age 32; 40 male) (28 new-diagnosis, 45 relapsed) were read independently by two radiologists selected from a pool of 13. Radiologists interpreted datasets using three sequential sequence blocks: (1) T2 weighted and steady state free precession gradient echo (SSFP) images alone (T2^); (2) T2 weighted and SSFP images with DWI (T2 + DWI^) and; (3) T2 weighted images, SSFP, DWI and post-contrast enhanced (CE) T1 images (T2 + DWI + CE^), documenting presence, location, and activity of small bowel disease. For each sequence block, sensitivity and specificity (readers combined) was calculated against an outcome-based construct reference standard. RESULTS 59/73 patients had small bowel disease. Per-patient sensitivity for disease detection was essentially identical (80 % [95 % CI 72, 86], 81 % [73,87], and 79 % [71,86] for T2^, T2 + DWI^and T2 + DWI + CE^respectively). Specificity was identical (82 % [64 to 92]). Per patient sensitivity for disease extent was 56 % (47,65), 56 % (47,65) and 52 % (43 to 61) respectively, and specificity was 82 % (64 to 92) for all blocks. Sensitivity for active disease was 97 % (90,99), 97 % (90,99) and 98 % (92,99), and specificity was also comparable between all sequence combination reads. Results were consistent across segments and newly diagnosed/relapse patients. CONCLUSION There is no additional diagnostic benefit of adding either DWI or CE to T2 FSE and SSFP sequences for evaluating small bowel Crohn's disease, suggesting MRE protocols can be simplified safely.

Abstract
AIMS Schaumann bodies were first identified in sarcoidosis by Dr Schaumann in 1941. They were also detected in 10% of Crohn's disease (CD) cases in a study involving patients with surgically resected CD. However, the characteristics and significance of Schaumann bodies in CD have yet to be fully elucidated. This study aimed to determine the pathological features and diagnostic significance of Schaumann bodies in various bowel diseases. METHODS Overall, 278 bowel specimens were collected from patients with CD, intestinal tuberculosis, ulcerative colitis, intestinal schistosomiasis, diverticulosis and idiopathic mesenteric vasculopathy. The frequency, pathology and clinical features of patients with Schaumann bodies were studied. RESULTS Schaumann bodies were present exclusively in CD (27.0%, 38 of 141) and were not detected in other intestinal diseases within the series. In CD, Schaumann bodies were deposited along the myenteric plexus of the muscularis propria (84.2%, 32 of 38). These bodies were small (diameter: 60.3±32.7 µm) and exhibited a low density in the intestinal wall (1.1±0.4 per low-power field). The majority were located within the cytoplasm of multinucleated giant cells (84.2%, 32 of 38) and were not found within or adjacent to granulomas. Notably, the number of female patients with CD and Schaumann bodies was higher than that of males. CONCLUSION Schaumann bodies are common in resected CD specimens, and their characteristic deposition pattern may serve as a diagnostic indication for CD.

Abstract
BACKGROUND Few studies evaluate the epidemiology and risk factors of Clostridioides difficile infection (CDI) in Asian patients with inflammatory bowel disease (IBD). We investigated the year-end prevalence, cumulative incidence and risk factors of CDI in Asian patients with IBD using a large-scale population-based cohort in Korea. METHODS Using the National Health Insurance Service database, we identified patients with IBD and sex- and age-matched controls without IBD between 2008 and 2018. The year-end prevalence and cumulative incidence of CDI were compared among patients with Crohn's disease (CD) and ulcerative colitis (UC) with controls. The risk factors for CDI were evaluated. RESULTS Among the 54,836 patients with IBD and 109,178 controls, CDI occurred in 293 patients with IBD and 87 controls. The annual year-end prevalence of CDI in patients with IBD increased from 8.6/10,000 persons in 2008 to 22.3/10,000 persons in 2018. The risk of CDI was higher in both patients with CD and UC than that in the matched controls (hazard ratio [HR], 7.285; 95% confidence interval [CI], 5.388-9.851; P < 0.001 and HR, 7.487; 95% CI, 5.796-9.670; P < 0.001, respectively). Among patients with IBD, the risk factors for CDI included older age, female sex, high Charlson comorbidity index score, and IBD-related medications including oral 5-aminosalicylic acid, immunomodulatory agents, biologics, and steroids used for > 90 days. CONCLUSION The risk of CDI in Korean patients with IBD was approximately seven times higher than that in controls without IBD, and the annual year-end prevalence of CDI continuously increased from 2008 to 2018.

Abstract
About 50% of Crohn's Disease (CD) patients undergo an intestinal resection during their lifetime. Although the patients experience a fairly long period of well-being after the intestinal resection, they presented a postoperative recurrence (POR) in 40% of cases within 5 years. In this case series, we aimed to evaluate the incidence of POR in CD patients with high risk for early POR, prophylactically treated with Vedolizumab. All consecutive CD patients (followed from 2017 to 2020) who underwent ileocolonic resection after the loss of response at anti-Tumor Necrosis Factor α (anti-TNFα) and with one or more risk factors for early POR were included. POR was defined as a Rutgeerts score (Ri) > 1 at the colonoscopic evaluation. All the included patients underwent a Magnetic resonance enterography (MRE) at least one year after the surgical resection. Six patients (4 Female; 2 Males) were included. At the first endoscopic evaluation, all patients were in endoscopic remission (5 patients Ri 0; 1 patient Ri 1). No stenosis nor other intestinal wall changes or complications were observed at MRE. Five patients underwent colonoscopy over two years of follow-up (median: 32 months; range 25-33). The Ri score was 0 in four patients, while the fifth patient showed severe endoscopic relapse. The same patient presented a clinical relapse (Harvey-Bradshaw index = 10) with a flare of disease in the colonic mucosa. These data suggest that early post-operative treatment with Vedolizumab could be a valuable strategy to be submitted to a prospective controlled trial for preventing POR.

Abstract
Dasatinib is a second-generation multityrosine kinase inhibitor used in the first-line and second-line treatment of Philadelphia chromosome-positive leukaemia. The most frequent type of Dasatinib-induced intestinal injury is haemorrhagic colitis; other morphologic patterns include apoptotic colopathy, CD8+ T-cell-mediated colitis and non-specific colitis. Aim of this study is to describe a novel Crohn's-like histopathologic pattern of Dasatinib-induced colitis. Four patients developed diarrhoea during Dasatinib treatment; colonoscopy was performed and biopsy sets were taken for histological analysis. All patients showed patchy, chronic active inflammation with cryptitis and microgranulomas (two patients). Ileal and rectal biopsies showed either no or mild, focal inflammation. An increase in lamina propria eosinophils was seen (two patients) and apoptoses were seen (three patients). Complete remission was observed after interruption of treatment. Dasatinib-induced colitis and Crohn's disease may share histologic features including microgranulomas, which can potentially lead to misdiagnosis if no information on treatment is provided.

Abstract
MANAGEMENT OF SECONDARY LESIONS IN ANO-PERINEAL CROHN'S DISEASE. Anoperineal involvement in Crohn's disease is common and affects around 1/3 of patients during their disease. It constitutes a pejorative factor with an increased risk of permanent colostomy and proctectomy and is associated with a major deterioration in quality of life. Secondary anal lesions in Crohn's disease are fistulas and abscesses. They are difficult to treat and often recurrent. A multidisciplinary medico-surgical management in several stages is essential. The classic sequence is based on a first phase of drainage of fistulas and abscesses, a second phase of medical treatment based primarily on anti-TNF alpha and finally a third phase of surgical closure of the fistula tract(s). Conventional closure techniques such as biologic glue, plug, advancement flap and intersphincteric ligation of the fistula tract have limited effectiveness, are not always feasible, require technical skills and some have an impact on anal continence. In recent years, we have witnessed a real enthusiasm generated by the arrival of cell therapy. This has not spared proctology since adipose-derived allogeneic mesenchymal stem cells have had Marketing Authorisation and have been reimbursed in France since 2020 in the treatment of complex anal fistulas in Crohn's disease after failure of at least one biologic therapy. This new treatment offers an additional alternative in patients often in a situation of therapeutic impasse. Preliminary results in real life are satisfactory with a good safety profile. However, it will be necessary to confirm these results in the longer term and to work to determine the profile of the patients who could benefit the most from this expensive therapy.

Abstract
BACKGROUND Metformin has pleiotropic effects including anti-inflammatory properties and effects on the gut microbiome. It is primarily used in the older population, where the occurrence of inflammatory bowel disease (IBD) is increasing. The aim of this study was to examine whether metformin protects against development of IBD. METHODS In the setting of a Danish nationwide population-based cohort, we conducted a nested case-control study using a new-user active comparator design. For each patient with IBD, we selected 10 IBD-free individuals matched on age, sex, and duration of follow-up. Conditional logistic regression was used to estimate odds ratios (ORs) of IBD. Adjustment included educational level, other immune-mediated inflammatory diseases, and use of dipeptidyl peptidase (DPP)-4 inhibitors and statins. RESULTS Among 302,863 IBD-free new users of oral glucose-lowering drugs, we identified 1271 patients who developed IBD and 12,676 matched IBD-free individuals. Mean age at IBD diagnosis was 66 (SD, 11) years. We found no association between ever use of metformin and risk of IBD, Crohn's disease or ulcerative colitis, adjusted OR 0.95 (95% CI 0.78-1.15), 0.87 (95% CI 0.60-1.26), and 1.04 (95% CI 0.83-1.31), respectively. Neither was the cumulative dose of metformin or the treatment duration with metformin associated with risk of IBD. CONCLUSIONS In this population-based study, we report that despite anti-inflammatory effects and a notable impact on the gut microbiome, metformin use is not associated with reduced risk of older onset IBD.

Abstract
BACKGROUND Vedolizumab (VDZ) is currently licensed for use in adults for the treatment of inflammatory bowel disease (IBD). We aimed to investigate the clinical course of pediatric-onset IBD following treatment with VDZ as more than a secondary biologic agent. We also evaluated factors associated with secondary loss of response (LOR) and durability of VDZ treatment. METHODS Pediatric-onset IBD patients diagnosed at an age younger than 18 years who had received VDZ as more than a secondary biologic agent were included in this retrospective observational study conducted at the Department of Pediatrics of two centers in Korea. Comparative analysis was conducted between groups divided according to the development of secondary LOR during VDZ treatment. RESULTS A total of 24 patients comprising 10 patients with Crohn's disease and 14 with ulcerative colitis were included. Of these, 19 were male and 5 were female. The mean age at diagnosis was 14.6 ± 2.5 years. The mean age at initiation of VDZ was 20.5 ± 2.8 years. Nine patients (37.5%) had received two or more biologic agents before starting VDZ. During a median of 0.9 years follow-up from VDZ initiation, 9 patients (37.5%) experienced LOR requiring interval shortening and 4 patients (16.7%) were changed to a different biologic agent. According to multivariate Cox proportional hazard regression analysis, administration of two or more biologic agents before VDZ treatment was the only factor positively associated with LOR (hazard ratio [HR], 5.6; 95% confidence interval [CI], 1.026-30.56; P = 0.047), while LOR was the only factor negatively associated with VDZ durability (HR, 0.003; 95% CI, 0.00-0.08; P = 0.010). No adverse events were observed during treatment with VDZ. CONCLUSION VDZ is safe and efficacious for the treatment of pediatric-onset IBD patients failing a primary biologic agent. The durability of VDZ may be enhanced by introducing VDZ earlier in the disease course. Further prospective studies in children are required in the future to validate these findings.

Abstract
Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is characterized by chronic, relapsing intestinal inflammation. Galectin-1 (Gal-1) is an endogenous lectin with key pro-resolving roles, including induction of T-cell apoptosis and secretion of immunosuppressive cytokines. Despite considerable progress, the relevance of Gal-1-induced T-cell death in inflamed tissue from human IBD patients has not been ascertained. Intestinal biopsies and surgical specimens from control patients (n = 52) and patients with active or inactive IBD (n = 97) were studied. Gal-1 expression was studied by RT-qPCR, immunoblotting, ELISA and immunohistochemistry. Gal-1-specific ligands and Gal-1-induced apoptosis of lamina propria (LP) T-cells were determined by TUNEL and flow cytometry. We found a transient expression of asialo core 1-O-glycans in LP T-cells from inflamed areas (p < 0.05) as revealed by flow cytometry using peanut agglutinin (PNA) binding and assessing dysregulation of the core-2 β 1-6-N-acetylglucosaminyltransferase 1 (C2GNT1), an enzyme responsible for elongation of core 2 O-glycans. Consequently, Gal-1 binding was attenuated in CD3+CD4+ and CD3+CD8+ LP T-cells isolated from inflamed sites (p < 0.05). Incubation with recombinant Gal-1 induced apoptosis of LP CD3+ T-cells isolated from control subjects and non-inflamed areas of IBD patients (p < 0.05), but not from inflamed areas. In conclusion, our findings showed that transient regulation of the O-glycan profile during inflammation modulates Gal-1 binding and LP T-cell survival in IBD patients.

Abstract
BACKGROUND SAMP1/YitFcsJ (SAMP1) mice spontaneously develop terminal ileitis resembling human Crohn disease. SAMP1 mice have exhibited alteration of epithelial cell lineage distribution and an overall proliferation of the crypt cell population; however, it has not been evaluated whether epithelial differentiation is impaired because of dysfunction of intestinal stem cells (ISCs) or their niche factors. METHODS Using the intestine of SAMP1 mice aged 10 to 14 weeks, morphometric alterations in the crypt-villus architecture, ISCs, crypt cells, and differentiated cells; organoid formation capacity of intestinal crypts; and niche signaling pathways were analyzed and compared with those of age-matched control AKR/J (AKR) mice. RESULTS The ileum of SAMP1 mice showed increased depth of intestinal crypts and decreased surface area of the villi compared with those in the ileum of AKR mice. The number of ISCs in the ileal crypts did not differ between SAMP1 and AKR mice; however, the number of Paneth cells decreased and the number of transient amplifying cells increased. The organoid formation rate of the ileal crypts of SAMP1 mice decreased significantly compared with that of AKR mice. The performance of RNA sequencing for intestinal crypts found that the expression of ISC niche factors, such as Wnt3, Dll1, and Dll4, was decreased significantly in the ileal crypts of SAMP1 mice compared with those of AKR mice. Among the ISC niche signals, the Notch signaling-related genes tended to be downregulated. In particular, immunocytochemistry revealed that the expression of Paneth cell-expressing Notch ligand Dll4 was significantly decreased in the intestinal tissue and organoids of SAMP1 mice compared with those of AKR mice. CONCLUSIONS Depletion of niche factors for ISCs contributes to the alteration of epithelial differentiation in SAMP1 mice.

Abstract
BACKGROUND & AIMS Dietary therapies based on exclusion of usual dietary elements induce remission in children with Crohn's disease (CD), whereas re-exposure induces rebound inflammation. We investigated whether a short trial of dietary therapy, to identify patients with and without a rapid response or remission on the diet (DiRe), can be used to predict success or failure of long-term dietary therapy. METHODS We collected data from the multicenter randomized trial of the CD exclusion diet (CDED). We analyzed data from 73 children with mild to moderate CD (mean age, 14.2 ± 2.7 y) randomly assigned to groups given either exclusive enteral nutrition (EEN, n = 34) or the CDED with 50% (partial) enteral nutrition (n = 39). Patients were examined at baseline and at weeks 3 and 6 of the diet. Remission was defined as CD activity index scores below 10 and response was defined as a decrease in score of 12.5 points or clinical remission. Inflammation was assessed by measurement of C-reactive protein. RESULTS At week 3 of the diet, 82% of patients in the CDED group and 85% of patients in the EEN group had a DiRe. Median serum levels of C-reactive protein had decreased from 24 mg/L at baseline to 5.0 mg/L at week 3 (P < .001). Among the 49 patients in remission at week 6, 46 patients (94%) had a DiRe and 81% were in clinical remission by week 3. In multivariable analysis, remission at week 3 increased odds of remission by week 6 (odds ratio, 6.37; 95% CI, 1.6-25; P = .008) whereas poor compliance reduced odds of remission at week 6 (odds ratio, 0.75; 95% CI, 0.012-0.46; P = .006). CONCLUSIONS For pediatric patients with active CD, dietary therapies (CDED and EEN) induce a rapid clinical response (by week 3). Identification of patients with and without a rapid response to diet might help identify those who, with compliance, will be in clinical remission by week 6 of the diet.

Abstract
Objective: To investigate the prevalence of Crohn's disease (CD) among urban employees in 24 provinces (municipalities and autonomous regions) in China in 2013. Method: The crude annual prevalence of CD among urban employees with medical insurance in 2013 was estimated by using the basic medical insurance database of 24 provinces (municipalities and autonomous regions), as well as the prevalence by sex, age and region. The age-standardized rate based on the 2010 census was also estimated. Results: The crude prevalence of CD among urban employees in 2013 was 3.2/100 000(95%CI:3.1/100 000-3.3/100 000) , and the sex-specific rate was 3.5/100 000 (95%CI:3.3/100 000-3.6/100 000) and 3.0/100 000 (95% CI:2.8/100 000-3.1/100 000) for male and female, respectively. The crude prevalence in different regions indicated that the highest crude prevalence was in the eastern region [5.6/100 000 (95% CI:5.4/100 000-5.8/100 000) ]. Conclusion: The prevalence of CD in China is still lower than that of the western countries, with difference varied in terms of age, gender and region.

Abstract
BACKGROUND & AIMS Inflammatory bowel diseases (IBDs) exist worldwide, with high prevalence in North America. IBD is complex and costly, and its increasing prevalence places a greater stress on health care systems. We aimed to determine the past current, and future prevalences of IBD in Canada. METHODS We performed a retrospective cohort study using population-based health administrative data from Alberta (2002-2015), British Columbia (1997-2014), Manitoba (1990-2013), Nova Scotia (1996-2009), Ontario (1999-2014), Quebec (2001-2008), and Saskatchewan (1998-2016). Autoregressive integrated moving average regression was applied, and prevalence, with 95% prediction intervals (PIs), was forecasted to 2030. Average annual percentage change, with 95% confidence intervals, was assessed with log binomial regression. RESULTS In 2018, the prevalence of IBD in Canada was estimated at 725 per 100,000 (95% PI 716-735) and annual average percent change was estimated at 2.86% (95% confidence interval 2.80%-2.92%). The prevalence in 2030 was forecasted to be 981 per 100,000 (95% PI 963-999): 159 per 100,000 (95% PI 133-185) in children, 1118 per 100,000 (95% PI 1069-1168) in adults, and 1370 per 100,000 (95% PI 1312-1429) in the elderly. In 2018, 267,983 Canadians (95% PI 264,579-271,387) were estimated to be living with IBD, which was forecasted to increase to 402,853 (95% PI 395,466-410,240) by 2030. CONCLUSION Forecasting prevalence will allow health policy makers to develop policy that is necessary to address the challenges faced by health systems in providing high-quality and cost-effective care.

Abstract
BACKGROUND & AIMS Patients with inflammatory bowel diseases who have postinflammatory polyps (PIPs) have an increased risk of colorectal neoplasia (CRN). European guidelines propose that patients with PIPs receive more frequent surveillance colonoscopies, despite limited evidence of this increased risk. We aimed to define the risk of CRN and colectomy in patients with inflammatory bowel diseases and PIPs. METHODS We conducted a multicenter retrospective cohort study of patients with inflammatory bowel diseases who underwent colonoscopic surveillance for CRN, from January 1997 through January 2017, at 5 academic hospitals and 2 large nonacademic hospitals in New York or the Netherlands. Eligible patients had confirmed colonic disease with duration of at least 8 years (or any duration, if they also had primary sclerosing cholangitis) and no history of advanced CRN (high-grade dysplasia or colorectal cancer) or colectomy. The primary outcome was occurrence of advanced CRN according to PIP status; secondary outcomes were occurrence of CRN (inclusive of low-grade dysplasia) and colectomy. RESULTS Of 1582 eligible patients, 462 (29.2%) had PIPs. PIPs were associated with more severe inflammation (adjusted odds ratio 1.32; 95% confidence interval [CI] 1.13-1.55), greater disease extent (adjusted odds ratio 1.92; 95% CI 1.34-2.74), and lower likelihood of primary sclerosing cholangitis (adjusted odds ratio 0.38; 95% CI 0.26-0.55). During a median follow-up period of 4.8 years, the time until development of advanced CRN did not differ significantly between patients with and those without PIPs. PIPs did not independently increase the risk of advanced CRN (adjusted hazard ratio 1.17; 95% CI 0.59-2.31). The colectomy rate was significantly higher in patients with PIPs (P = .01). CONCLUSIONS In a retrospective analysis of data from 2 large independent surveillance cohorts, PIPs were associated with greater severity and extent of colon inflammation and higher rates of colectomy, but were not associated with development of any degree of CRN. Therefore, intervals for surveillance should not be shortened based solely on the presence of PIPs.

Abstract
Crohn's disease is an autoimmune disease that predominantly affects the gastrointestinal tract. Crohn's disease is diagnosed at a young age and runs a chronic course with acute flare-ups. When patients with Crohn's disease present with flare-ups at the emergency department, they are usually managed in a way similar to patients with acute abdomen; there is no consensus about the most appropriate imaging work-up for patients with flare-ups of Crohn's disease. Thus, we decided to review the literature about the imaging tests indicated (whether related to their diagnostic performance or to lower exposure to ionizing radiation) for acute flare-ups in patients with Crohn's disease.

Abstract
A potential role for viral infections has been implicated in inflammatory bowel disease (IBD) unresponsive to medical treatment. It is well known that Epstein-Barr virus (EBV) infection can elicit a brisk mononuclear response in the gastrointestinal tract. The aim of this study was to further evaluate the role of EBV in patients with refractory IBD and compare them with nonrefractory IBD cases. Surgically resected colonic specimens from 67 patients with refractory IBD (62 with ulcerative colitis, 3 patients with Crohn disease, and 2 patients with indeterminate colitis) were retrieved. Twelve colectomy specimens from patients with ulcerative colitis who had undergone resections for dysplasia or endometriosis were included as controls. Highly sensitive EBV-encoded small RNA1 (EBER-1) in situ hybridization was performed on a representative block from each specimen. EBER-1 reactivity was graded as absent, focal, or diffuse. EBV was detected in 60% (40/67) of patients with refractory IBD compared with 25% (3/12) of the control group (P < .05). Focal EBER-1 positivity was present in 45% of cases of refractory IBD compared with 25% of controls. Diffuse EBER-1 reactivity was seen in 15% of cases of refractory IBD (10/67); none of the samples from the control group contained diffuse EBER-1 positivity. There was a positive correlation between EBER positivity and depth of inflammation and mucosal ulceration in patients with refractory IBD. Our findings suggest a potential role for EBV infection in patients with refractory IBD.

Abstract
Inflammatory bowel disease (IBD) has been associated with the development of both gastrointestinal and extraintestinal malignancy. The role of therapy in the development of malignancy in IBD has been controversial. We present the case of a 40-year-old female patient with long-standing mild IBD, who developed an undifferentiated pleomorphic sarcoma of the inguinal region and provide a brief review of the relevant literature. While our case likely represents a coincidence of two unrelated pathological entities, clinicians should keep in mind the possibility of soft tissue sarcomas in patients chronically treated with anti-inflammatory agents.

Abstract
Background: Crohn's disease and Ulcerative colitis are known as inflammatory bowel disease with high morbidity which are as a result of increasing immune responses to intestinal microbiota in genetically susceptible individuals. The association of adherent invasive Escherichia coli with Crohn's disease in human has been discussed for decades. The principal aim of this study was to assess the relationship between adherent invasive Escherichia coli in Iranian patients with Crohn's disease.
Methods: The presence of adherent invasive Escherichia coli DNA and viable adherent invasive Escherichia coli cells were identified through PCR and conventional culture methods, respectively. All the specimens were subsequently cultured in Hi Chrome Agar medium.
Results: Using molecular assay, the invasive plasmid antigen H and invasion-association locus genes were detected from tissue samples confirming the presence of adherent-invasive Escherichia coli. The invasive plasmid antigen H was detected in 46.7% of CD and 13.3% of healthy peoples. The invasion-association locus gene was found in 36.7% of patients with Crohn's disease and 10% in individuals without IBD.
Conclusion: This study demonstrated an increased frequency of adherent invasive E. coli with invasive plasmid antigen H and invasion-association locus genes from patients with CD in comparison to control individuals. Moreover, it was shown that adherent invasive E. coli with the invasive plasmid antigen H and invasion-association locus genes can act as a predisposing factor in the development of IBD.

Abstract
OBJECTIVE A relatively large proportion of patients with Crohn disease (CD) develop complications including abscess formation, stricture, and penetrating disease. A subset of patients will have genital and reproductive organ involvement of CD, resulting in significant morbidity. These special circumstances create unique management challenges that must be tailored to the activity, location, and extent of disease. Familiarity with the epidemiology, pathogenesis, imaging features, and treatment strategies for patients with genital CD can aid imaging diagnoses and guide appropriate patient management. The purpose of this study is to illustrate the spectrum of CD in the genital tract and reproductive organs and discuss the complex management strategies in these patients as it relates to imaging. CONCLUSION Given the impact on patient outcome and treatment planning, familiarity with the epidemiology, pathogenesis, imaging features, and treatment of patients with genital Crohn disease can aid radiologic diagnoses and guide appropriate patient management.

Abstract
Introduction Recently, it has been suggested an association between red cell distribution width (RDW) and Crohn's disease activity index (CDAI), but its use is not yet performed in daily clinical practice. Objectives To determine whether RDW can be used as a marker of Crohn's disease (CD) activity. Methods This was a cross-sectional study including patients with CD, observed consecutively in an outpatient setting between January 1st and September 30th 2013. Blood cell indices, erythrocyte sedimentation rate (ESR), and C-reactive protein were measured. CD activity was determined by CDAI (active disease if CDAI ≥ 150). Associations were analyzed using logistic regression (SPSS version 20). Results 119 patients (56% female) were included in the study with a mean age of 47 years (SD 15.2). Twenty patients (17%) had active disease. The median RDW was 14.0 (13–15). There was an association between RDW and disease activity (p = 0.044). After adjustment for age and gender, this association remained consistent (OR 1.20, 95% CI 1.03–1.39, p = 0.016). It was also found that the association between RDW and disease activity was independent of hemoglobin and ESR (OR 1.36, 95% CI 1.08–1.72, p = 0.01) and of biologic therapy (OR 1.19, 95% CI 1.03–1.37, p = 0.017). A RDW cutoff of 16% had a specificity and negative predictive value for CDAI ≥ 150 of 88% and 86%, respectively. Conclusion In this study, RDW proved to be an independent and relatively specific marker of CD activity. These results may contribute to the implementation of this simple parameter, in clinical practice, aiming to help therapeutic decisions.

Abstract
Inflammatory bowel disease (IBD) is a chronic idiopathic inflammatory disease of the gastrointestinal (GI) tract. In the past decade a shift in the treatment paradigm of IBD has ensued. The availability of drugs capable of inducing mucosal healing, combined with the recognition that IBD is not an intermittent disease, but rather a progressive one causing bowel damage and disability, led us to a more stringent strategy. Tailored therapy with more aggressive treatment in high-risk patients, treating beyond symptoms, intervening early before damage occurs, optimizing therapeutic regimens, and actively pursuing sustained remission and sustained control of inflammation are strategies that are slowly being incorporated in our clinical practice. Furthermore, new drugs targeting different immunological pathways, such as vedolizumab, have recently been approved and therefore more therapeutic resources for patients failing anti-tumour necrosis factor alpha (anti-TNFα) agents will be available. The future years look promising for IBD. Hopefully the new trends in IBD management, combined with new drugs, will make possible to change the course of disease and provide better therapy and quality of life for patients suffering from this disabling disease.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) has a physical, psychological and social impact, often compromising the patient's ability to perform daily activities. Recently a new measurement for disability in IBD was developed. The Inflammatory Bowel Disease-Disability Score (IBD-DS) comprises the following domains: mobility, self-care, major daily life activities, gastrointestinal-related problems, mental health and interaction with the environment. The aim of our study was to translate to Portuguese and to validate the IBD-DS. METHODS Eighty-five patients, 55 with Crohn's disease (CD) and 30 with ulcerative colitis (UC), completed the Portuguese version of the IBD-DS and the short inflammatory bowel disease questionnaire (SIBDQ-10 questions). Disease activity was assessed using the Harvey-Bradshaw (HB) for CD and partial Mayo score (pMayo) for UC. Pearson's correlation coefficient was used to assess the correlation between the IBD-DS and SIBDQ. The Student's t-test was used to compare the mean of IBD-DS between active and inactive disease. Statistical analysis was performed with SPSS 21.0 and the statistical level of significance (α) was established at 5%. RESULTS In our study, a significant negative correlation between the IBD-DS and the SIBDQ was observed (r = -0.858, p < 0.001 for CD and r = -0.933, p < 0.001 for UC). There was a statistically significant difference of the mean of IBD-DS between inactive vs. active disease (93.78 vs. 117.57, p = 0.016 for CD and 78.96 vs. 137.14, p < 0.001 for UC). CONCLUSION The Portuguese version of the inflammatory bowel disease-disability score has a strong correlation with patients' quality of life and clinical disease activity and was shown to be a valid tool to measure disability in patients with inflammatory bowel disease.

Abstract
BACKGROUND Tumour necrosis factor (TNF) plays a key role in the pathogenesis of Crohn disease (CD). RDP58 is a novel anti-inflammatory decapeptide which was developed using a novel rational design strategy. Recently, RDP58 has proved to be a potent inhibitor of TNF production at a post-transcriptional step. The aims of this study were to investigate the anti-inflammatory properties of RDP58 ex vivo in human CD and in vivo in an experimental model colitis. METHODS Biopsies and lamina propria mononuclear cells from inflamed colonic mucosa of 18 CD patients were cultured for 24 h in the presence or absence of RDP58. TNF was quantified in a bioassay; interferon (IFN)-γ and interleukin (IL)-1β levels were measured by enzyme-linked immunosorbent assays. Colitis was induced by intra-rectal administration of 2, 4, 6 trinitrobenzene sulphonic acid (TNBS) in rats. Inflammation was assessed following 7 days of oral therapy with RDP58 or vehicle alone. RESULTS RDP58 led to decreased TNF and IFN-γ (but not IL-1β) production by biopsies and lamina propria mononuclear cells from CD patients. In rats with TNBS-induced colitis, oral RDP58 therapy reduced weight loss and diarrhoea and improved macroscopic and histological inflammation scores. CONCLUSIONS Our results suggest that RDP58 may be an effective therapy for CD with the clinical advantage of an oral administration.

Abstract
BACKGROUND Gastrin plays an important role in the regulation of gastric acid secretion in humans. Tumour necrosis factor alpha (TNF-α) stimulates gastrin release from antral G cells in vitro. The aim was to determine whether gastrin release decreases in patients with Crohn disease treated with monoclonal antibody to TNF-α. METHODS Twenty-five consecutive patients with Crohn disease (10 M, 15 F; 18 with fistulas) were treated with a single intravenous infusion of the monoclonal antibody to TNF-α, infliximab, at a dose of 5 mg/kg. Basal and bombesin stimulated gastrin was measured after an overnight fast immediately before and 2 weeks after infliximab. Helicobacter pylori status was determined by serology. RESULTS Twenty-two patients were H. pylori-negative. Basal plasma gastrin was 21 (16-26) pmol/L before and 19 (15-25) pmol/L after infliximab (NS). Bombesin stimulated gastrin decreased from 49 (40-62) pmol/L before to 36 (33-59) pmol/L (P < 0.005) 2 weeks after infliximab. CONCLUSION Gastrin release in response to bombesin decreases in patients with Crohn disease treated with infliximab.

Abstract
BACKGROUND Lactose intolerance with adult-onset is due to the inadequate enzymatic activity of lactase-phlorizin hydrolase (LPH). It is frequently seen in patients with Crohn disease, but the mechanism remains to be elucidated. Two DNA genotypes, C/C_₁₃₉₁₀ and G/G_₂₂₀₁₈, located upstream from the LCT locus, the gene encoding for LPH, were recently identified as representing genetic markers for lactose intolerance. We utilized these two DNA genotypes to study their role in inflammatory bowel disease. METHODS We investigated the prevalence of these two DNA variants using specific restriction enzyme digest assays in 166 patients with Crohn disease, in 120 healthy first-degree relatives of Crohn disease patients, in 63 patients with ulcerative colitis and in 187 healthy individuals. RESULTS The analysis revealed a frequency of 21.4% of the 2 genotypes for adult-type hypolactasia in our studied German cohort of healthy individuals, which is higher than previously reported (15%) based on the hydrogen (H₂) breath test. This might indicate a higher sensitivity of genotyping, but it has to be confirmed in larger cohorts. No significant difference was detectable in the frequency of the C/C_₁₃₉₁₀ and G/G_₂₂₀₁₈ genotypes in patients with Crohn Disease (C/C_₁₃₉₁₀: 21.7%; G/G_₂₂₀₁₈: 22.3%) compared to first-degree relatives (C/C_₁₃₉₁₀: 21.7%; G/G_₂₂₀₁₈: 20.8%), patients with ulcerative colitis (C/C_₁₃₉₁₀: 20.3%; G/G_₂₂₀₁₈: 20.3%) and healthy individuals (C/C_₁₃₉₁₀: 21.4%; G/G_₂₂₀₁₈: 21.4%). CONCLUSIONS The C/C_₁₃₉₁₀ and G/G_₂₂₀₁₈ genotype of adult-type hypolactasia is not associated with susceptibility to the pathogenesis of Crohn disease and ulcerative colitis.
