Objective Data on the course of severe COVID-19 in inflammatory bowel disease (IBD) patients remains limited. We aimed to determine the incidence rate and clinical course of severe COVID-19 in the heavily affected South-Limburg region in the Netherlands. Methods All COVID-19 patients admitted to the only two hospitals covering the whole South-Limburg region between February 27, 2020 and January 4, 2021 were included. Incidence rates for hospitalization due to COVID-19 were determined for the IBD (n = 4980) and general population (n = 597,184) in South-Limburg. Results During a follow-up of 4254 and 510,120 person-years, 20 IBD patients (0.40%; 11 ulcerative colitis (UC), 9 Crohn’s disease (CD)) and 1425 (0.24%) patients from the general population were hospitalized due to proven COVID-19 corresponding to an incidence rate of 4.7 (95% Confidence interval (CI) 3.0–7.1) and 2.8 (95% CI 2.6–2.9) per 1000 patient years, respectively (Incidence rate ratio: 1.68, 95% CI 1.08–2.62, p = 0.019). Median age (IBD: 63.0 (IQR 58.0–75.8) years vs. general population: 72.0 (IQR 62.0–80.0) years, p = 0.10) and mean BMI (IBD: 24.4 (SD 3.3) kg/m2 vs. general population 24.1 (SD 4.9) kg/m2, p = 0.79) at admission were comparable in both populations. As for course of severe COVID-19, similar rates of ICU admission (IBD: 12.5% vs. general population: 15.7%, p = 1.00), mechanical ventilation (6.3% vs. 11.2%, p = 1.00) and death were observed (6.3% vs. 21.8%, p = 0.22). Conclusion We found a statistically significant higher rate of hospitalization due to COVID-19 in IBD patients in a population-based setting in a heavily impacted Dutch region. This finding reflects previous research that showed IBD patients using systemic medication were at an increased risk of serious infection. However, although at an increased risk of hospitalization, clinical course of severe COVID-19 was comparable to hospitalized patients without IBD.

ObjectivePatients with inflammatory bowel disease (IBD) have an elevated risk of mental illness. We determined the incidence and correlates of new-onset mental illness associated with IBD during pregnancy and post partum.DesignThis cohort study using population-based health administrative data included all women with a singleton live birth in Ontario, Canada (2002–2014). The incidence of new-onset mental illness from conception to 1-year post partum was compared between 3721 women with and 798 908 without IBD, generating adjusted HRs (aHR). Logistic regression was used to identify correlates of new-onset mental illness in the IBD group.ResultsAbout 22.7% of women with IBD had new-onset mental illness versus 20.4% without, corresponding to incidence rates of 150.2 and 132.8 per 1000 patient-years (aHR 1.12, 95% CI 1.05 to 1.20), or one extra case of new-onset mental illness per 43 pregnant women with IBD. The risk was elevated in the post partum (aHR 1.20, 95% CI 1.09 to 1.31), but not during pregnancy, and for Crohn’s disease (aHR 1.12, 95% CI 1.02 to 1.23), but not ulcerative colitis. The risk was specifically elevated for a new-onset mood or anxiety disorder (aHR 1.14, 95% CI 1.04 to 1.26) and alcohol or substance use disorders (aHR 2.73, 95% CI 1.42 to 5.26). Predictors of a mental illness diagnosis were maternal age, delivery year, medical comorbidity, number of prenatal visits, family physician obstetrical care and infant mortality.ConclusionWomen with IBD were at an increased risk of new-onset psychiatric diagnosis in the postpartum period, but not during pregnancy. Providers should look to increase opportunities for prevention, early identification and treatment accordingly.

Abstract Background The study’s objective was to investigate the incidence and risk factors associated with Clostridioides difficile (previously known as Clostridium) infection (CDI) in children with inflammatory bowel disease (IBD) in the province of Manitoba. Methods Our longitudinal population-based cohort was comprised of all children and young adults aged <17 years diagnosed with IBD in the Canadian province of Manitoba between 2011 and 2019. The diagnosis of CDI was confirmed based on the Triage C. difficile immunoassay and polymerase chain reaction assay to detect the presence of toxigenic C. difficile. The Fisher exact test was used to examine the relationship between categorical variables. A Cox regression model was used to estimate the risk of CDI development in IBD patients. Results Among 261 children with IBD, 20 (7.7%) developed CDI with an incidence rate of 5.04 cases per 1000 person-years, and the median age at diagnosis (interquartile range) was 12.96 (9.33–15.81) years. The incidence rates of CDI among UC and CD patients were 4.16 cases per 1000 person-years and 5.88 cases per 1000 person-years, respectively (P = 0.46). Compared with children without CDI, those who had CDI were at increased risk of future exposure to systemic corticosteroids (adjusted hazard ratio [aHR], 4.38; 95% confidence interval [CI], 1.46–13.10) and anti–tumor necrosis factor (anti-TNF) biologics (aHR, 3.31; 95% CI, 1.11–9.90). The recurrence rate of CDI in our pediatric IBD population was 25%. Conclusions Our findings confirm that children with IBD are at high risk of developing CDI, which may predict future escalation of IBD therapy.

Abstract Background Patients with inflammatory bowel disease are at increased risk of extracolonic cancers. Little is known regarding this risk following total colectomy [TC]. Methods Patients who underwent TC for inflammatory bowel disease in Denmark during 1977–2013 were identified from the Danish National Patient Registry. Incidence rates of extracolonic cancers were determined through record linkage to the Danish Cancer Registry and compared with expected incidence rates in the general population. Standardized incidence ratios [SIRs] were calculated as the observed vs expected cancer incidence. Results In total, 4430 patients (3441 with ulcerative colitis [UC]; 989 with Crohn’s disease [CD]) were followed for 54,183 person-years after TC. Following their surgery, 372 patients were diagnosed with extracolonic cancer compared to 331 expected [SIR = 1.1 (95% confidence interval {CI}: 1.0–1.2)]. The risk of extracolonic cancer overall was increased among patients with CD and TC (SIR = 1.5 [95% CI: 1.2–1.8]), but not among patients with UC and TC (SIR = 1.0 [95% CI: 0.9–1.2]). Patients with UC and TC had a higher risk of intestinal extracolonic cancer (SIR = 2.0 [95% CI: 1.4–2.7]). Patients with CD and TC had a higher risk of smoking-related cancers (SIR = 1.9 [95% CI: 1.2–2.9]), intestinal extracolonic cancer (SIR = 3.1 [95% CI: 1.6–5.5]) and immune-mediated cancers (SIR = 1.5 [95% CI: 1.0–2.1]). Conclusion Patients with CD and TC had a higher risk of extracolonic cancer overall compared to the general population, while patients with UC and TC did not. Site-specific cancer risk varied according to inflammatory bowel disease type.

Background: Although inflammatory bowel disease (IBD) has been more predominant in white populations, an increasing incidence of IBD in nonwhites has been reported. We sought to evaluate the incidence rates and temporal trends of IBD by race and ethnicity. Methods: The resources of the Rochester Epidemiologic Project were used to identify 814 county residents newly diagnosed with IBD from 1970 through 2010. Race was categorized into whites and nonwhites. Ethnicity was categorized into Hispanic and non-Hispanic. Incidence rates were estimated and adjusted for age and sex to the 2010 United States (US) population. Trends in incidence rates were evaluated by Poisson regression. Results: The adjusted annual incidence rate of IBD for whites was 21.6 cases per 100,000 person-years [95% confidence interval (CI), 20.0–23.1] and for nonwhites it was 13 per 100,000 (95% CI, 8.3–17.5). The incidence rates for whites and nonwhites increased by 39% and 134%, respectively, from 1970 through 2010. The adjusted annual incidence rate of IBD for Hispanics was 15 cases per 100,000 person-years (95% CI, 6.3–23.6) and for non-Hispanics was 20 per 100,000 (95% CI, 18.5–21.6). The incidence rate for Hispanics decreased by 56%, while the rate for non-Hispanics increased by 33%, from 1985 through 2010. In a Poisson regression, white race ( p < 0.0001), a later year of diagnosis ( p < 0.001), male sex ( p < 0.001) and younger age ( p = 0.009) were significantly associated with a higher incidence rate of IBD. Conclusions: There were significant racial and ethnic differences in the incidence and temporal trends of IBD over the last four decades in this US population-based cohort.

Abstract Background Toxigenic Clostridioides difficile (C. difficile), previously known as Clostridium difficile, is an anaerobic gram-positive spore-forming opportunistic pathogen associated with profuse diarrhoea and gastroenteritis associated mortality, especially in children with inflammatory bowel disease (IBD). The aim of this work was to investigate the incidence and risk factors associated with Clostridioides difficile infection (CDI) in children with IBD in the province of Manitoba, Canada. Methods Our longitudinal population-based cohort comprised of all children and young adults &lt;17 years diagnosed with IBD in the Canadian province of Manitoba between 2011 and 2019. The diagnosis of CDI was confirmed based on the Triage C. difficile immunoassay and polymerase chain reaction assay to detect the presence of toxigenic C. difficile. Fisher’s exact test was used to examine the relationship between categorical variables. Cox-regression model was used to estimate the risk of CDI development in IBD patients. Results Among the 261 children with IBD, 20 (7.7%) developed CDI with an incidence rate of 5.04 cases per 1000 person-years and the median age at diagnosis of 12.96 years (IQR: 9.33–15.81). The incidence rate of CDI among UC and CD patients were 4.16 cases per 1000 person-years and 5.88 cases per 1000 person-years, respectively (p = 0.46). Compared to children without CDI, those who had CDI were at increased risk of future exposure to systemic corticosteroids (hazard ratio (HR) = 4.30; 95% CI: 1.44–12.87) and anti-tumour necrosis factor (TNF) biologics (HR = 3.37; 95% CI: 1.13–10.09). Recurrence rate of CDI in our paediatric IBD population was 25%. Conclusion Our findings confirm that children with IBD are at a high risk of developing CDI, which may predict future escalation of IBD therapy.

Abstract Background The broad use of immunosuppressants and biologicals in Inflammatory Bowel Disease (IBD) patients increases the susceptibility to severe infections, and possibly COVID-19. Recently, in a Swedish population-based study it was suggested that IBD patients are at an increased risk of hospitalization for COVID-19, although course of COVID-19 did not differ from controls. Data on the outcome of COVID-19 in IBD patients from heavily affected regions remain, however, limited. South-Limburg has the second highest COVID-19 mortality rate in the Netherlands. We aimed to determine the incidence rate and outcome of severe COVID-19 in IBD patients in a population-based setting in South-Limburg. Methods We identified all IBD patients who presented at the emergency department (ED) of the only two hospitals covering the whole South-Limburg region with COVID-19 associated symptoms between February 27 and November 1, 2020. Confirmed COVID-19 diagnosis was defined by a combination of COVID-19 associated symptoms and either a positive SARS-CoV-2 PCR or a CT-CORADS score ≥4. As primary outcome, the incidence rate of severe COVID-19 (i.e. confirmed COVID-19 diagnosis requiring hospitalization, and/or resulting in ICU admission or death) was determined. Baseline characteristics and data on COVID-19 course were collected. At present, the total IBD population in South-Limburg is set at 4980 patients. Results During a follow-up of 3384 person-years, a total of 61 IBD patients (1.22%) presented with COVID-19 associated symptoms at one of the two hospital’s ED. Of these, 18 IBD patients (0.36%; 11 UC, 7 CD) fulfilled the criteria for severe COVID-19, corresponding to an incidence rate of 5.3 per 1000 person-years. Furthermore, 12/18 patients were using immunosuppressive medication for their IBD. Mean age at time of admission was 64.5 years (SD: 10.8) and 55.6% were male. All hospitalized patients had at least one comorbidity (with ≥ 1 comorbidity in 13/18 patients (72.2%)), cardiovascular disease being most prevalent (12/18). Mean BMI at time of admission was 27.3 (SD: 4.2). Thirteen patients (72.2%) required oxygen support and three patients (16.7%) ICU admission (of which two needed mechanical ventilation), translating to an incidence rate of 0.9 per 1000 patient-years for ICU admission. Median length of hospitalization was 11 days (IQR: 5.3–18.3). No IBD patients died due to severe COVID-19. Conclusion The incidence rate of severe COVID-19 among IBD patients in a population-based setting in a heavily affected region was 5.3 per 1000 person-years. Despite frequent use of immunosuppressive medication and high region-specific mortality rates, clinical outcomes of severe COVID-19 were comparable to the general population and in line with recent literature.

Abstract Background and Aims Canada has one of the highest inflammatory bowel disease (IBD) incidence rates worldwide. Higher IBD incidence rates have been identified among urban regions compared to rural regions. The study objectives were to (i) estimate IBD incidence rates in Saskatchewan from 1999 to 2016 and (ii) test for differences in IBD incidence rates for rural and urban regions of Saskatchewan. Methods A population-based study was conducted using provincial administrative health databases. Individuals aged 18+ years with newly diagnosed Crohn’s disease or ulcerative colitis were identified using a validated case definition. Generalized linear models with a negative binomial distribution were used to estimate incidence rates and incidence rate ratios (IRRs) adjusted for age group, sex and rurality with 95% confidence intervals (CIs). Results The average annual incidence rate of IBD among adults in Saskatchewan decreased from 75/100,000 (95% CI 67 to 84) in 1999 to 15/100,000 (95% CI 12 to 18) population in 2016. The average annual incidence of IBD declined significantly by 6.9% (95% CI −7.6 to −6.2) per year. Urban residents had a greater overall risk of IBD (IRR = 1.19, 95% CI 1.11 to 1.27) than rural residents. This risk difference was statistically significant for Crohn’s disease (IRR = 1.25, 95% CI 1.14 to 1.36), but not for ulcerative colitis (IRR = 1.08, 95% CI 0.97 to 1.19). Conclusions The incidence of IBD in Saskatchewan dropped significantly from 1999 to 2016 with urban dwellers having a 19% higher risk of IBD onset compared to their rural counterparts. Health care providers and decision-makers should plan IBD-specific health care programs considering these specific IBD rates.

Summary Background: There is an impression mostly from specialty clinics that patients with inflammatory bowel disease (IBD) have an increased risk of venous thromboembolic disorders. Our aim was to determine the incidence of deep venous thrombosis (DVT) and pulmonary embolism (PE) from a population-based database of IBD patients and, to compare the incidence rates to that of an age, gender and geographically matched population control group. Methods: IBD patients identified from the administrative claims data of the universal provincial insurance plan of Manitoba were matched 1:10 to randomly selected members of the general population without IBD by year, age, gender, and postal area of residence using Manitoba Health’s population registry. The incidence of hospitalization for DVT and PE was calculated from hospital discharge abstracts using ICD-9-CM codes 451.1, 453.x for DVT and 415.1x for PE. Rates were calculated based on person-years of follow-up for 1984-1997. Comparisons to the population cohort yielded age-adjusted incidence rate ratios (IRR). Rates were calculated based on person-years of follow-up (Crohn’s disease = 21,340, ulcerative colitis = 19,665) for 1984-1997. Results: In Crohn’s disease the incidence rate of DVT was 31.4/10,000 person-years and of PE was 10.3/10,000 person-years. In ulcerative colitis the incidence rates were 30.0/10,000 person-years for DVT and 19.8/10,000 person-years for PE. The IRR was 4.7 (95% CI, 3.5-6.3) for DVT and 2.9 (1.8-4.7) for PE in Crohn’s disease and 2.8 (2.1-3.7) for DVT and 3.6 (2.5-5.2) for PE, in ulcerative colitis. There were no gender differences for IRR. The highest rates of DVT and PE were seen among patients over 60 years old; however the highest IRR for these events were among patients less than 40 years. Conclusion: IBD patients have a threefold increased risk of developing DVT or PE.
