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.

Abstract Background Canada has one of the highest inflammatory bowel disease (IBD) incidence rates worldwide, although within Canada rates vary. Evidence show increasing incidence rates of IBD in Ontario (i.e. adults aged 30–60), stable in Alberta and decreasing in Manitoba. Additionally, higher incident rates of IBD have been identified among urban regions compared to rural regions. There is limited data on the incidence of IBD in Saskatchewan. Aims The study objectives were to 1) estimate IBD incidence rates in Saskatchewan from 1999 to 2016, and 2) test for differences in IBD incidence rates for rural and urban regions of Saskatchewan. Methods A population-based study was conducted using linked provincial administrative health databases. Individuals age 18+ old with newly diagnosed Crohn’s disease (CD) or ulcerative colitis (UC) 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 (IRR) adjusted for age group, sex, and rurality with 95% confidence intervals (95%CI). Results In total, 4,908 newly diagnosed individuals with IBD were included. The average annual incidence rate of IBD decreased from 75 (95%CI 67–84) per 100,000 people in 1999 to 15 (95%CI 12–18) per 100,000 population in 2016. This decrease was evident in both UC (from 36/100,000 [95%CI 31–42] in 1999 to 6/100,000 [95%CI 4–8] in 2016) and CD (37/100,000 [95%CI 32–42] in 1999 to 8/100,000 [95%CI 6–10] in 2016). A significant decline of 6.9% (95%CI 6.2–7.6) in the average annual incidence of IBD was estimated between 1999 and 2016 (see Figure 1). Urban residents had a greater overall risk of IBD (IRR=1.19, 95%CI 1.11–1.27) than rural residents. This risk difference was statistically significant for CD (IRR=1.25, 95%CI 1.14–1.36), but not UC (IRR=1.08, 95%CI 0.97–1.19). Conclusions A decreasing trend in IBD incidence in Saskatchewan was identified after adjusting for age group, sex, and rural/urban region of residence. Around 150 new cases of IBD are still diagnosed annually in Saskatchewan, but this estimate is lower than estimates from other provinces. Urban dwellers have a 25% higher risk of CD onset compared to their rural counterparts. This finding could suggest the presence of specific risk factors in urban settings that require further investigation. Health care providers and decision-makers should plan IBD-specific health care programs taking into account these specific IBD rates in Saskatchewan.

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.

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.

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.

Annotation. At the turn of the 21st century, chronic inflammatory bowel disease (CIBD) has become a global disease with accelerating morbidity in industrialized countries with a prevalence exceeding 0.3%. These data underscore the need for research into the prevention of inflammatory bowel disease and innovations in health care systems to manage this complex and costly disease. The information from a personal anamnesis of 40 women patients with ulcerative colitis (clinical group (main). In the second group (control), 30 practically healthy pregnant women with a physiological course of gestation were included, which did not have in their history of inflammatory intestinal diseases. Statistical processing of research results was performed using the software package Statistica 6.0. The arithmetic mean (M) and the standard deviation error (± m) (p<0.05) were determined, as well as the odds ratio (OR), confidence interval (CI) at p=95%. It was found that for women with ulcerative colitis is characterized by the presence of a history of obstetric pathology, such as: spontaneous miscarriage of OR 3.33, 95% CI [1.06-10.53], p=0.04 and blood secretions of OR 3.0, 95% CI [1.00-8.98], p=0.0496; among extragenital pathology in the anamnesis: children's infectious diseases of OR 4.85, 95% CI [1.25-18.85], p=0.02, chronic bronchitis of OR 7.54, 95% CI [1,56-36, 41], p=0.01, varicose veins OR 4.33, 95% CI [1.11-16.95], p=0.035, chronic gastritis OR 6.0, 95% CI [1,23-29, 31], p=0.03, anemia of OR 15.0, 95% CI [4.53-49.68], p<0.0001, allergy history of OR 6.65, 95% CI [1.73-25.60], p=0.006; among gynecological complications – premenstrual syndrome OR 6.0, 95% CI [1.55-23.15], p=0.009, algomenorrhea OR 8.14, 95% CI [2.12-31.24], p=0.002 , salpingo-oophoritis, OR 7.54, 95% CI [1.56-36.41], p=0.01. Because CIBD during pregnancy is associated with an increased risk of adverse effects on the mother and fetus, information on socio-anamnestic and clinical analysis of pregnant women with ulcerative colitis will be useful to health care providers in making decisions about CIBD during pregnancy.

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 There is limited to no evidence of the prevalence and incidence rates of inflammatory bowel disease (IBD) among Indigenous peoples. In partnership with Indigenous patients and family advocates, we aimed to estimate the prevalence, incidence, and trends over time of IBD among First Nations (FNs) since 1999 in the Western Canadian province of Saskatchewan. Methods We conducted a retrospective population-based study linking provincial administrative health data from the 1999-2000 to 2016-2017 fiscal years. An IBD case definition requiring multiple health care contacts was used. The prevalence and incidence data were modeled using generalized linear models and a negative binomial distribution. Models considered the effect of age groups, sex, diagnosis type (ulcerative colitis [UC], Crohn disease [CD]), and fiscal years to estimate prevalence and incidence rates and trends over time. Results The prevalence of IBD among FNs increased from 64/100,000 (95% confidence interval [CI], 62-66) in 1999-2000 to 142/100,000 (95% CI, 140-144) people in 2016-2017, with an annual average increase of 4.2% (95% CI, 3.2%-5.2%). Similarly, the prevalence of UC and CD, respectively, increased by 3.4% (95% CI, 2.3%-4.6%) and 4.1% (95% CI, 3.3%-4.9%) per year. In contrast, the incidence rates of IBD, UC, and CD among FNs depicted stable trends over time; no statistically significant changes were observed in the annual change trend tests. The ratio of UC to CD was 1.71. Conclusions We provided population-based evidence of the increasing prevalence and stable incidence rates of IBD among FNs. Further studies are needed in other regions to continue understanding the patterns of IBD among Indigenous peoples.

The aim of this study was to determine the annual incidence and geographic distribution of pediatric inflammatory bowel disease (IBD) in Croatia. This is a prospective, cohort, multicenter observational study based on the data obtained from the Croatian national registry for children with IBD. Children and adolescents younger than 18 years diagnosed with IBD, in time period between June 1, 2016, and May 31, 2017, were recruited. In total, 51 new cases were identified; 19 Crohn’s disease, 28 ulcerative colitis, and 8 IBD-unclassified. Male preponderance of all 3 types of the disease was noticed. The median age at diagnosis was 14.8 years. The calculated annual incidence of pediatric IBD per 100 000 persons per year was 7.05 (2.63 for Crohn’s disease, 3.87 for ulcerative colitis, and 0.55 for IBD-unclassified). A north to south gradient was observed with almost 2 times higher incidence in the northern region of the country.

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 &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. 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.
