Objective. The objective is the investigation of Joint Hypermobility (JH) and the Hypermobility Syndrome (HMS) in patients with inflammatory bowel disease (IBD).Methods. We examined 83 patients with IBD and 67 healthy individuals for the presence of JH. Patients were excluded if they were under 18 or over 50 years of age and if they had other conditions which affect joint mobility. Thex2and the Fisher exact test were used appropriately between study groups. Odds ratios (ORs) for the risk of JH and HMS in IBD groups were calculated.Results. A total of 150 individuals (83 IBD patients and 67 healthy controls) participated in the study. 69 IBD patients, 41 with Crohn's Disease (CD) and 28 with ulcerative colitis (UC), were finally eligible. JH was detected in 29 CD patients (70.7%), in 10 UC patients (35.7%), and in 17 healthy control subjects (25.4%). Significant difference was detected on JH in CD patients as compared to UC patients (P=.0063) and controls (P<.0001). The estimated OR for JH was 7.108 (95% CI: 2.98–16.95) in CD and 1.634 (95% CI: 0.63–4.22) in UC patients. HMS was detected in 5 (12.2%) CD and in 1 (3.57%) UC patients. The OR for HMS in CD was 3.75 (95% CI: 0.41–34.007), while 7 (17.1%) CD patients had overlapping symptoms for both HMS and early spondylarthropathy.Conclusions. JH and the HMS are common in CD patients, thus articular manifestations should be carefully interpreted. This implies an involvement of collagen varieties in the pathogenesis of IBD.

Abstract Background Patients with inflammatory bowel disease (IBD) have a 1.5–3 fold increase in the risk of venous thromboembolism (VTE). Additionally, VTE in patients with IBD is associated with a 2.1 fold increase in mortality compared to the general population. The risk of VTE is increased with active inflammation. It is speculated that individuals with IBD are inconsistently advised about VTE risk. This study evaluated the frequency of counseling about VTE in IBD patients. Methods A retrospective medical record review of all IBD patients seen at a university gastroenterology practice during a 5 year period was performed. Patients’ age, gender, disease type and documented counselling about VTE risk were obtained. A database was created maintaining patient confidentiality. Analysis was conducted using Fisher’s Exact Test with significance set at p&lt; 0.05. The study was approved by the university IRB. Results Records of 381 patients were reviewed. There were 209 females and 172 males with a mean age of 44 years (range 20–82). 279 had ulcerative colitis, 96 had Crohn’s disease and 6 had indeterminate colitis. Self-reported ethnicity included 195 White, 97 Black/African-American (AA), 11 Asian, 1 Hawaiian, 34 other and 43 did not report their ethnicity. 13 (3.4%) patients (7 females, 6 males) were counselled about VTE risk. The 7 women who were counselled were &lt;50, with no significant difference in counselling of women &lt;50 compared to women &gt;50 (p=0.11). The 6 men who were counseled were &lt;50, with no significant difference in counseling of men &lt;50 compared to men &gt;50 (p=0.09). There was no difference in the rate of counselling based upon gender (p=1.000), ethnicity (Whites vs. non-Whites, p=0.77; Whites vs. AA, p=1.00) or disease type (p=0.31). Discussion Venous thromboembolism is a known risk of inflammatory bowel disease. While VTEs infrequently occur in IBD patients, it is important that there is awareness about the potential risk. This study revealed that VTE risk is rarely discussed with IBD patients. While this study is limited by single institutional design, size and reliance on documentation, it suggests that increased efforts can be made to educate IBD patients about VTEs. Recognition of VTE risks can improve IBD management and optimize clinical outcomes.

Abstract Background Intestinal dendritic cells (DC) and macrophages drive disease progression in patients with inflammatory bowel disease (IBD). We aimed to characterize the activation and homing profile of human circulating DC and monocyte subsets in healthy control patients (CP) and IBD patients. Methods Eighteen CP and 64 patients with IBD were categorized by diagnoses of Crohn disease (CD) and ulcerative colitis (UC), either endoscopically active (inflamed) or quiescent. Circulating type 1 conventional DC, type 2 conventional DC, plasmacytoid DC, classical monocytes, nonclassical monocytes, and intermediate monocytes were identified by flow cytometry in each individual and characterized for the expression of 18 markers. Association between DC/monocytes and IBD risk was tested by logistic regression. Discriminant canonical analyses were performed to classify the patients in their own endoscopy category considering all markers on each subset. Results CCRL1, CCR3, and CCR5 expression on circulating type 1 DC; CCRL1 expression on nonclassical monocytes; and CCR9 and β7 expression on classical monocytes allowed us to discriminate among the different study groups. Indeed, the same markers (excluding β7) were also associated with IBD when all DC and monocyte subsets were considered at the same time. Conclusions Monitoring the phenotype of human circulating DC and monocyte subsets may provide novel tools as biomarkers for disease diagnosis (CD/UC) or mucosal status (inflamed/noninflamed) in the absence of an invasive colonoscopy.

An altered ceramide composition in patients with inflammatory bowel disease (IBD) has been reported recently. The aim of this study was to evaluate the concentrations of sphingolipids in the serum of treatment-naive children with newly diagnosed IBD and to determine the diagnostic value of the tested lipids in pediatric IBD. The concentrations of sphingolipids in serum samples were evaluated using a quantitative method, an ultra-high-performance liquid chromatography-tandem mass spectrometry in children with Crohn’s disease (CD) (n=34), ulcerative colitis (UC) (n = 39), and controls (Ctr) (n = 24). Among the study groups, the most significant differences in concentrations were noted for C16:0-LacCer, especially in children with CD compared to Ctr or even to UC. Additionally, the relevant increase in C20:0-Cer and C18:1-Cer concentrations were detected in both IBD groups compared to Ctr. The enhanced C24:0-Cer level was observed only in UC, while C18:0-Cer only in the CD group. The highest area under the curve (AUC), specificity, and sensitivity were determined for C16:0-LacCer in CD diagnosis. Our results suggest that the serum LacC16-Cer may be a potential biomarker that distinguishes children with IBD from healthy controls and differentiates IBD subtypes. In addition, C20:0-Cer and C18:0-Cer levels also seem to be closely connected with 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&gt;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.

The Difference

Abstract Background With the approval of tofacitinib, an oral Janus Kinase (JAK) inhibitor, modulation of kinase activity has been added to the therapeutic armamentarium of inflammatory bowel disease (IBD). Despite its established efficacy, at least a third of patients will not respond to this or other therapeutic options such as anti-tumour necrosis factor (TNF), anti-interleukin (IL)23/IL12 compounds or vedolizumab. A better understanding of the inflammatory profile could aid in tailoring drugs to individual patients. We therefore explored mucosal cytokine, chemokine and kinase activity profiles in IBD. Methods Colonic mucosal biopsies were collected from (1) patients with Crohn’s disease (CD, N = 8), (2) patients with ulcerative colitis (UC, N = 8) and (3) healthy controls (N = 4). IBD samples were collected both from inflamed and non-inflamed tissue from the same patients. All IBD patients were biological-naïve and had not used corticosteroids in the past 3 months. Biopsies were snap frozen for later kinase activity determination or directly used in a 24-h explant culture. Whole biopsy kinase activity (tyrosine, serine and threonine kinases) was assessed using the Pamgene platform. A 64-analyte panel was examined in the supernatant of the cultured biopsies employing a multiplex assay (Luminex). Results Whole-biopsy kinase activity differed between inflamed and non-inflamed mucosa of IBD patients, with more overall tyrosine kinase activity in inflamed mucosa in UC, and serine/threonine kinase activity in inflamed mucosa in CD as compared with non-inflamed mucosa (Figure 1). The kinase activity profile of non-inflamed mucosa of CD and UC patients was similarly different from mucosa of healthy control participants (Figure 2). The cytokine and chemokine profile of inflamed biopsies differed from non-inflamed IBD biopsies and healthy control biopsies, with higher levels of S100A8, TNFα, IL-6, oncostatin M (OSM) and triggering receptor expressed on myeloid cells-1 (TREM-1), amongst others (Figure 3). Conclusion In IBD, inflammation in the mucosa can be characterised both by explant-culture and kinase activity assessment. The difference in kinase activity between non-inflamed IBD mucosa and healthy control mucosa suggests the presence of sub-clinical alterations in cell signalling. The observed differences in the kinase, cytokine and chemokine profiles underscore the importance of this approach in the elucidation of the pathophysiology in 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.

AbstractBackground and AimsReadmission within 30 days in inflammatory bowel disease (IBD) patients increases treatment costs and serves as a quality indicator. The LACE (Length of stay, Acuity of admission, Charlson comorbidity index, Emergency Department visits in past 6 months) index is used to predict the risk of unplanned readmission within 30 days. The aim of this study was to evaluate the accuracy of using the LACE index in IBD.MethodsCalculation of LACE index was done prospectively for IBD patients admitted to a single tertiary care center. Patient, disease, and treatment characteristics, as well as index hospitalization characteristics including indication for admission and disease activity measures were retrospectively recorded. Descriptive statistics and univariable exact logistic regression analyses were performed.ResultsIn total, 64 IBD patients were admitted during the study period. The 30-day readmission rate of IBD patients was 19% and overall median LACE index was 6, with IQR 6–7. LACE index categorized 16% of IBD patients in low-risk group, 82% in moderate risk group, and 2% in high-risk group. LACE index did not predict 30-day readmission (OR 1.35, CI: 0.88–2.18, P = 0.19). There was no significant difference in 30-day readmission rates with inpatient antibiotic or narcotic use, admission C-reactive protein (CRP), anemia, IBD duration, maintenance therapy, or prior IBD operation. For every 1 day increase in length of stay (LOS), patients were 8% more likely (OR: 1.08, 95% CI: 1.00–1.16) to be readmitted within 30 days (P = .05).ConclusionsLACE index does not accurately identify 30-day readmission risk in the IBD population. As increased LOS is associated with higher risk, there may be benefit for targeted strategic resource allocation via specialized services.

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.
