Abstract Background Colorectal strictures have been considered independent risk factors for neoplasia in patients with inflammatory bowel disease (IBD). We examined the association between colorectal stricture and subsequent risk of colorectal neoplasia (CRN) in patients with IBD colitis undergoing colonoscopic surveillance. Methods We conducted a retrospective cohort analysis of patients with IBD colitis enrolled in colonoscopic surveillance for CRN at an academic medical center between 2005 and 2017. Inclusion criteria were IBD involving the colon for ≥8 years (or any duration with primary sclerosing cholangitis [PSC]) undergoing surveillance. Exclusion criteria were advanced CRN (ACRN; colorectal cancer [CRC] or high-grade dysplasia [HGD]) prior to or at enrollment, prior colectomy, or limited (<30%) disease extent or proctitis. Multivariable logistic and Cox regression analysis estimated the association between colorectal stricture on the index colonoscopy and ACRN, CRN (indefinite dysplasia, low-grade dysplasia, HGD, CRC), or colectomy. Results Among 789 patients with IBD undergoing CRC surveillance, 72 (9%; 70 with Crohn’s colitis) had a colorectal stricture on index colonoscopy. There was no significant difference in the frequency of ACRN or requirement for colectomy between patients with vs without a colorectal stricture (P > .05). Colorectal stricture was not associated with subsequent ACRN (adjusted odds ratio [aOR], 1.41; 95% CI, 0.49–4.07), CRN (aOR, 1.15; 95% CI, 0.51–2.58), or colectomy (aOR, 1.10; 95% CI, 0.65–1.84). Conclusions In this analysis of patients with IBD colitis undergoing CRN surveillance, the presence of a colorectal stricture was not independently associated with risk of ACRN or colectomy. Multicenter, prospective studies are needed to confirm these findings, particularly in patients with ulcerative colitis–associated colorectal stricture.

Abstract Background and Aims The prognosis of lymphoma that occurs in patients with inflammatory bowel disease [IBD] is poorly known. Methods A multicentre retrospective cohort analysis was done in seven French tertiary centres from 1999 to 2019. Only lymphoma occurring in patients with previous established diagnosis of IBD were analysed. The primary outcome was progression-free survival at 3 years. Results A total of 52 patients [male 65%, Crohn’s disease 79%, median age 48.3 years, median duration of IBD 10.1 years] were included, of whom 37 had been previously exposed to immunosuppressants and/or biologics for at least 3 months and 20 had primary intestinal lymphomas. The lymphoma histological types were: diffuse large B cell lymphomas [N = 17], Hodgkin lymphomas [N = 17], indolent B cell lymphomas [N = 12], and others including T cell lymphomas, mantle cell lymphomas, and unclassifiable B cell lymphoma [N = 6]. The median follow-up after lymphoma was 5.1 years (interquartile range [IQR] 4–7.8). Progression-free survival at 3 years was 85% in the overall population (95% confidence interval [CI] 75%–96%) with no significant difference between the exposed and unexposed group, 79% for patients exposed to immunosuppressants and/or biologics [95% CI 67%–94%], and 83% for patients diagnosed with primary intestinal lymphoma [95% CI 67%–100%]. No relapse of IBD has been observed during chemotherapy. The IBD relapse rate at the end of the last chemotherapy cycle was 23% at 3 years [95% CI 11%-39%] in the overall population. Conclusions In this large cohort, the prognosis for lymphomas occurring in IBD appears to be good and similar to what is expected, irrespective of the exposure to biologics and/or immunosuppressants.

Prevention Approach

Abstract One of the most feared complications of inflammatory bowel disease [IBD]-associated colitis is colorectal cancer. When considering the substantial increase in the prevalence of IBD, without any anticipated decline, coupled with decreasing colectomy rates for dysplasia and expanding medical options for effectively controlling inflammation, it is predicted that the pool of people living with—and ageing with—colonic IBD, who are recommended to undergo lifelong colonoscopic surveillance for colorectal neoplasia, will strain existing resources and challenge the sustainability of current guideline-based surveillance recommendations. At the same time, we are missing the opportunity for early detection in a group that is overlooked as high-risk, as a substantial proportion of colorectal cancers are being diagnosed in individuals with colonic IBD who have disease duration shorter than when guidelines recommend surveillance initiation. Here, we reappraise: 1] inflammation as a dynamic risk factor that considers patients’ cumulative course; 2] time of screening initiation that is not based primarily on absolute disease duration; and 3] surveillance intervals as an iterative determination based on individual patient factors and consecutive colonoscopic findings. This Viewpoint supports a paradigm shift that will ideally result in a more effective and higher-value colorectal cancer prevention approach in IBD.

Background:Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn’s disease (CD), is considered as a risk factor of low bone mineral density (BMD). In fact, the prevalence of osteoporosis ranges from 17% to 41% in IBD patients. The possible contributing factors may include malabsorption, glucocorticoid treatment and coexisting comorbiditiesObjectives:The purpose of our work was to determine the frequency and the determinants of osteoporosis in patients with IBD and to assess whether there is a difference in BMD status between UC and CD.Methods:This is a retrospective study, over a period of 5 years (from January 2014 to December 2018) and including patients followed for IBD who had a measurement of BMD by DEXA. Clinical, anthropometric and densitometric data (BMD at the femoral and vertebral site) were recorded. The WHO criteria for the definition of osteoporosis and osteopenia were applied.Results:One hundred and five patients were collected; among them 45 were men and 60 were women. The average age was 45.89 years old. The average body mass index (BMI) was 25.81 kg/m2 [16.44-44.15]. CD and UC were diagnosed in respectively 57.1% and 42.9%. A personal history of fragility fracture was noted in 4.8%. Hypothyroidism was associated in one case. Early menopause was recorded in 7.6%. 46.8% patients were treated with corticosteroids. The mean BMD at the vertebral site was 1.023 g/cm3 [0.569-1.489 g/cm3]. Mean BMD at the femoral site was 0.920g/cm3 [0.553-1.286g / cm3]. The mean T-score at the femoral site and the vertebral site were -1.04 SD and -1.27 SD, respectively. Osteoporosis was found in 25.7% and osteopenia in 37.1%. Osteoporosis among CD and UC patients was found in respectively 63% and 37%. The age of the osteoporotic patients was significantly higher compared to those who were not osteoporotic (52.23 vs 43.67 years, p = 0.01). We found a significantly higher percentage of osteoporosis among men compared to women (35.6% vs 18.3%, p=0.046). The BMI was significantly lower in the osteoporotic patients (23.87 vs 26.48 kg/m2, p=0.035) and we found a significant correlation between BMI and BMD at the femoral site (p=0.01). No increase in the frequency of osteoporosis was noted in patients treated with corticosteroids (27.9% vs 21.6%, p=0.479). Comparing the UC and CD patients, no difference was found in baseline characteristics, use of steroids or history of fracture. No statistically significant difference was found between UC and CD patients for osteoporosis(p=0.478), BMD at the femoral site (p=0.529) and at the vertebral site (p=0.568).Conclusion:Osteoporosis was found in 25.7% of IBD patients without any difference between CD and UC. This decline does not seem to be related to the treatment with corticosteroids but rather to the disease itself. Hence the interest of an early screening of this silent disease.Disclosure of Interests:None declared

Abstract Background Appropriate management of inflammatory bowel disease (IBD) often requires multiple specialist appointments per year. Living in rural locations may pose a barrier to regular specialist care. Saskatchewan (SK) has a large rural population. Prior to COVID-19, telehealth (TH) in SK was not routinely used for either patient assessment or follow up. Furthermore, TH was exclusively between hospitals and specific TH sites without direct contact using patient’s personal phones. Aims The objective of this study was to assess the differences in demographics, disease characteristics, outcomes, and health care utilization between patients from rural SK with IBD who used TH and those who did not. Methods A retrospective chart review was completed on all rural patients (postal code S0*) with IBD in SK who were followed at the Multidisciplinary IBD Clinic in Saskatoon between January 2018 and February 2020. Patients were classified as using TH if they had ever used it. Information on demographics, disease characteristics, and access to IBD-related health care in the year prior to their last IBD clinic visit or endoscopy was collected. Data was not collected for clinic visits after March 1, 2020 as all outpatient care became remote secondary to the COVID-19 pandemic. Mean, standard deviations, median and interquartile ranges (IQR) were reported. Mann-Witney U and Chi-Square tests were used to determine differences between the groups. Results In total, 288 rural SK IBD patients were included, 30 (10.4%) used TH and 258 (89.6%) did not. Patient demographics were not significantly different between the two groups; although, there was a statistically significant difference in the proportion of ulcerative colitis patients (17% TH vs. 38% non-TH, p=0.02). The percentage of patients with clinical remission was 87% for TH patients and 74% for non-TH patients (p=0.13). There were no significant differences in health care utilization patterns and biochemical markers of disease, including c-reactive protein (CRP) and fecal calprotectin (FCP) (p>0.05). Conclusions Prior to the pandemic, a small percentage of patients with IBD in rural SK ever used TH. A small proportion of UC patients used TH. No significant differences in disease characteristics, outcomes, or health care utilization were identified. Further study is warranted to identify barriers to use of this technology to tailor care to this patient group and improve access to care, especially now as the COVID-19 pandemic has drastically changed the use of virtual care.

Background: Anti-tumor necrosis factor (TNF) agents are increasingly used for rheumatic diseases and inflammatory bowel disease (IBD), but are associated with the development of anti-TNF-induced lupus (ATIL). Nonetheless, few ATIL studies on non-Caucasian IBD patients exist. Here, we investigated the incidence, clinical features, and risk factors of ATIL in Korea. Methods: We retrospectively reviewed the medical records of IBD patients undergoing anti-TNF therapy at our tertiary IBD center between 2008 and 2020. ATIL was diagnosed as a temporal association between symptoms and anti-TNF agents, and the presence of at least one serologic and non-serologic American College of Rheumatology criterion. The risk factors for ATIL occurrence were assessed using multivariate Cox regression analysis. Results: Of 1362 IBD patients treated with anti-TNF agents, 50 (3.7%) ATIL cases were suspected, of which 14 (1.0%) received a definitive diagnosis. Arthritis and mucocutaneous symptoms were observed in 13 and 4 patients, respectively. All ATIL cases were positive for anti-nuclear and anti-dsDNA antibodies. Four patients (30.8%) improved while continuing anti-TNF therapy. At the final follow up, the ATIL group ( n = 14) had a lower IBD remission rate (30.8% versus 68.8%, p = 0.019) than the non-ATIL group ( n = 36). Ulcerative colitis and longer disease duration were associated with ATIL occurrence, with hazard ratios of 7.017 ( p = 0.005) and 1.118 ( p = 0.002), respectively. Conclusion: Although rare, ATIL is associated with poor treatment response to IBD in Korean patients. ATIL should be considered if arthritis and mucocutaneous symptoms develop during anti-TNF therapy for IBD.

Objective Hepatitis B virus (HBV) infection remains a significant public health challenge, particularly for immunocompromised patients. Our aim was to evaluate the serologic immunity in immunocompromised rheumatology and inflammatory bowel disease (IBD) patients, assess factors for serologic non-immunity and evaluate their response to one HBV booster dose. Methods Immunocompromised rheumatology and IBD patients with completed HBV screening were identified. A chart review was performed to collect demographics, clinical information, baseline HBV serology results, and serologic response to booster vaccination. Serologic nonimmunity was defined as a negative/indeterminate hepatitis B surface antibody (anti-HBs) level. Results Among 580 patients, 71% were non-immune. The highest portion of non-immune patients were 11-18 years old (p 0.004). There was no significant difference between immune and non-immune patients with regards to diagnosis (p 0.342), age at diagnosis (p 0.639), duration of treatment (p 0.069) or type of medications (p 0.080). Sixty-two percent of those who received a booster vaccine were re-screened, and most (68%) seroconverted. In those 18 years or older, only half seroconverted. Conclusion Results of this study support the benefit of HBV screening in immunosuppressed patients. Beginning at age 11 years most patients lacked serologic immunity to HBV. Seroconversion for most patients 11-18 years occurred after one booster vaccine. Thus, for immunocompromised patients without recent HBV serologic data, obtaining the HBV serology beginning at age 11 years might be considered. Those 18 years and older were least likely to seroconvert after one booster, indicating that they may benefit from receiving the three-dose HBV vaccine series.
