The Impact

The impact of COVID-19 on inflammatory bowel disease (IBD) patients under pharmacological immunosuppression is still not clearly understood. We investigated the incidence of COVID-19 and the impact of immunosuppression and containment measures on the risk of SARS-CoV-2 infection in a large IBD cohort, from a multicenter cohort from 21st of February to 30th of June, 2020. Ninety-seven patients with IBD (43 UC, 53 CD, one unclassified IBD) and concomitant COVID-19 over a total of 23,879 patients with IBD were enrolled in the study. The cumulative incidence of SARS-CoV-2 infection in patients with IBD vs. the general population was 0.406% and 0.402% cases, respectively. Twenty-three patients (24%) were hospitalized, 21 (22%) had pneumonia, four (4%) were admitted to the Intensive Care Unit, and one patient died. Lethality in our cohort was 1% compared to 9% in the general population. At multivariable analysis, age > 65 years was associated with increased risk of pneumonia and hospitalization (OR 11.6, 95% CI 2.18–62.60; OR 5.1, 95% CI 1.10–23.86, respectively), treatment with corticosteroids increased the risk of hospitalization (OR 7.6, 95% CI 1.48–40.05), whereas monoclonal antibodies were associated with reduced risk of pneumonia and hospitalization (OR 0.1, 95% CI 0.04–0.52; OR 0.3, 95% CI 0.10–0.90, respectively). The risk of COVID-19 in patients with IBD is similar to the general population. National lockdown was effective in preventing infection in our cohort. Advanced age and treatment with corticosteroids impacted negatively on the outcome of COVID-19, whereas monoclonal antibodies did not seem to have a detrimental effect.

Background and Aims. The impact of COVID-19 has been of great concern in patients with inflammatory bowel disease (IBD) worldwide, including an increased risk of severe outcomes and/or possible flare of IBD. This study aims to evaluate prevalence, outcomes, the impact of COVID-19 in patients with IBD, and risk factors associated with severe COVID-19 or flare of IBD activity. Methods. A consecutive cohort of IBD patients who were diagnosed with COVID-19 infection and followed up at the McGill University Health Care Centre was obtained between March 1, 2020, and April 30, 2021. Demographics, comorbidities, IBD (type, treatments, pre- and post-COVID-19 clinical activity, biomarkers, and endoscopic activity), and COVID-19-related outcomes (pneumonia, hospitalization, death, and flare of IBD disease) were analyzed. Results. A cohort of 3,516 IBD patients was included. 82 patients (2.3%) were diagnosed with COVID-19 infection (median age: 39.0 (IQR 27.8–48.0), 77% with Crohn’s disease, 50% were female). The prevalence of COVID-19 infection in IBD patients was significantly lower compared to the general population in Canada and Quebec (3.5% versus 4.3%, p < 0.001 ). Severe COVID-19 occurred in 6 patients (7.3%); 2 patients (2.4%) died. A flare of IBD post-COVID-19 infection was reported in 8 patients (9.8%) within 3 months. Biologic therapy was held during active COVID-19 infection in 37% of patients. Age ≥55 years (odds ratio (OR): 11.1, 95% CI: 1.8–68.0), systemic corticosteroid use (OR: 4.6, 95% CI: 0.7–30.1), active IBD (OR: 3.8, 95% CI: 0.7–20.8), and comorbidity (OR: 4.9, 95% CI: 0.8–28.6) were factors associated with severe COVID-19. After initial infection, 61% of IBD patients received COVID-19 vaccinations. Conclusion. The prevalence of COVID-19 infection among patients with IBD was lower than that in the general population in Canada. Severe COVID-19, mortality, and flare of IBD were relatively rare, while a large proportion of patients received COVID-19 vaccination. Older age, comorbidities, active IBD disease, and systemic corticosteroid, but not immunosuppressive or biological therapy, were associated with severe COVID-19 infection.

Abstract Background Inflammatory bowel disease (IBD) frequently affects women during their reproductive years. Although the impact of pregnancy in patients with established IBD has been widely studied, the characteristics and outcomes of patients who develop a new diagnosis of IBD during pregnancy or the postpartum year (“pregnancy-onset”) is not well characterized. Methods We identified all patients with pregnancy-onset IBD between 2006 and 2018 at 2 major academic referral centers. Patient and disease characteristics were abstracted and compared to those of control patients with IBD not diagnosed during pregnancy or postpartum. Diagnostic and therapeutic interventions were noted, as were long-term outcomes including disease treatment course, hospitalizations, and surgery. Results We identified 50 patients with pregnancy-onset IBD and 100 control patients matched for year of diagnosis. The mean age of diagnosis and duration of follow-up was similar among both patients and control patients (aged 30.4 vs 28.5 years). Among patients with pregnancy-onset disease, 30% noted symptom onset in the first trimester, 22% in the second, 24% in the third, and 24% in the postpartum year. Patients with pregnancy-onset IBD were more likely to be diagnosed with ulcerative colitis compared with control patients (76% vs 56%; P = 0.02). On multivariable analysis, pregnancy onset-disease had a 4-fold increase in the risk of hospitalization (28% vs 13%; adjusted odds ratio 4.18; 95% confidence interval, 1.26-13.91). This increased risk persisted even after excluding any index hospitalizations during pregnancy. Conclusions Patients with pregnancy-onset IBD more commonly develop ulcerative colitis and have a higher risk of disease-related hospitalizations.

Abstract Background Streptococcus pneumoniae is an important pathogen responsible for severe pneumococcal diseases, including pneumonia, bacteremia/sepsis, and meningitis. Inflammatory bowel disease (IBD) patients have an increased risk for infections due to an altered immune system and treatment with immunosuppressive medications. The aim of this study was to assess the prevalence of severe pneumococcal disease (SPD) and evaluate the impact of pneumococcal vaccination on the risk of SPD in Veterans with IBD. Methods Subjects with IBD and SPD were identified from the VA Health Administration database using ICD9/10 codes. Pneumococcal vaccination and use of immunosuppressant medications were collected. Risk of SPD was evaluated using an adjusted Cox proportional hazards model controlling for demographics, medications, vaccination, and comorbidities. Results A total of 1798 cases of SPD were identified (283 pneumonia, 1,513 bacteremia, and 2 meningitis). SPD patients were older (60.9 years vs 59.4 years; p&lt;0.001), had more comorbidities (Charlson Comorbidity Index of 2.11 vs. 0.96; p&lt;0.001) and had increased mortality (4.6% vs. 1.5%, p&lt;0.001). The risk of SPD was increased in Crohn’s disease (HR 1.15; 95% CI 1.05-1.27) and with more comorbidities (HR 1.45; 95% CI 1.42-1.48). Use of immunosuppressive medications increased the risk of SPD. Receipt of PCV13 either alone or in combination with PPSV23 predicted a five-fold decreased risk of SPD compared with no vaccination. Conclusion Vaccination with PCV13 alone or in combination with PPSV23 and revaccination with PPSV23, was protective against SPD. All IBD patients should be evaluated for pneumococcal vaccination, particularly those receiving or expected to receive immunosuppressive therapies.

The role of early-life environmental exposures on Inflammatory Bowel Disease (IBD) onset remains unclear. We aimed to quantify the impact of perinatal conditions and antibiotic use in the first 6 and 12 months of life, on the risk of childhood-onset IBD, in a birth cohort of the region Friuli-Venezia Giulia (Italy). A nested case-control design on a longitudinal cohort of 213,515 newborns was adopted. Conditional binomial regression models were used to estimate Odds Ratios (OR) with 95% confidence intervals (CI) for all analyzed risk factors. We identified 164 individuals with IBD onset before the age of 18 years and 1640 controls. None of the considered perinatal conditions were associated with IBD. Analyses on antibiotic exposure were based on 70 cases and 700 controls. Risks were significantly higher for children with ≥4 antibiotic prescriptions in the first 6 and 12 months of life (OR = 6.34; 95%CI 1.68–24.02 and OR = 2.91; 95%CI 1.31–6.45, respectively). This association was present only among patients with Crohn’s disease and those with earlier IBD onset. We found that perinatal characteristics were not associated to IBD, while the frequent use of antibiotics during the first year of life was associated to an increased risk of developing subsequent childhood-onset IBD.

Abstract Background The presence of serrated lesions (SLs) is an established risk factor for colorectal neoplasia development in the general population. However, the impact of SLs on the colorectal neoplasia risk in inflammatory bowel disease (IBD) patients is unknown. In addition, SLs might have been misclassified in IBD patients in the past, in part due to revisions of classification systems. Presently, SLs are categorised as hyperplastic lesions, sessile SLs, and traditional serrated adenomas. We aimed (1) to compare the colorectal neoplasia risk in IBD patients with SLs vs. IBD patients without SLs, and 2) to study the subclassification of SLs in IBD patients before and after histopathological review by two expert gastrointestinal pathologists. Methods We identified all IBD patients with colonic SLs from 1996 to 2019 in a tertiary referral centre using the local histopathology database. Patients with neoplasia prior to SL diagnosis were excluded. Clinical data from patients’ charts were retrieved until June 2019. A subgroup of 135 SLs was reviewed by two pathologists. The log-rank analysis was used to compare the cumulative (advanced) neoplasia incidence in IBD patients with SL vs. IBD patients without SL undergoing surveillance in the same time period. Patients were censored at the end of surveillance or at colectomy. Results We identified 376 SLs in 204 IBD patients (61.9% ulcerative colitis (UC)). In the original reports, 91.9% was classified as a hyperplastic lesion. After histopathological review, 120/136 (88%) of the SLs were confirmed (16 were no SL). Of the 120 confirmed SLs, 62.2% was classified as a sessile SL, 37.8% as a hyperplastic lesion, and 0.8% as a traditional serrated adenoma. The mean time from IBD diagnosis to the first serrated lesion was 14.3 ( ± 12.3) years. A total of 41/204 (20.0%) of patients developed neoplasia (3 CRC, 3 HGD, and 35 LGD; including 2 HGD and 17 LGD at the moment of serrated lesion detection). In the 304 patients without SL (52.6% UC), 63 developed neoplasia (20.7%; 8 CRC, 5 HGD and 50 LGD). Patients who received follow-up colonoscopies after SL (n = 127) had an increased cumulative risk of neoplasia (p &lt; 0.01), but no increased risk of advanced neoplasia (p = 0.50) compared with the group of IBD patients without SL (Figure 1). Conclusion The presence of SLs in IBD patients was associated with a relatively high risk of synchronous colorectal neoplasia as well as an increased risk of subsequent neoplasia, although not with an increased risk of advanced neoplasia. Histopathological review confirmed the SL diagnosis in the majority of lesions, although a large proportion of the hyperplastic lesions was reclassified as a sessile SL.

<b><i>Introduction:</i></b> Patients with inflammatory bowel disease (IBD) do not seem to be at increased risk of infection by SARS-CoV-2, but there is a concern whether immunosuppressive therapy may be associated with more severe disease. Several clinical practice recommendations have been published to help guide IBD care during the COVID-19 pandemic. Nonetheless, few studies have addressed patients’ perspectives and fears. We aimed to evaluate Portuguese IBD patients’ perspectives on the clinical management of their disease during the SARS-CoV-2 pandemic as well as the impact on their professional life. <b><i>Methods:</i></b> An anonymous electronic survey was created using REDCap and was distributed by the Portuguese Association of Inflammatory Bowel Disease (APDI) between May and August 2020. Patients’ perspectives on immunosuppressive therapy, disease management, interaction with gastroenterology departments, and the impact of the pandemic in their professional life were assessed. Patients’ proposals to improve medical care were also evaluated. Descriptive analysis and logistic regression were performed. <b><i>Results:</i></b> A total of 137 participants answered the survey (79.6% females, mean age 41.7 ± 12.1 years). Although having IBD and receiving treatment with immunosuppressors (thiopurines, steroids, or biologics) were considered promotors of anxiety, most patients (85.4%) agreed that disease remission was a priority and only a minority of patients interrupted their treatment during the pandemic. In multivariate analysis, active disease, biologic treatment, and use of corticosteroids in the last 3 months were perceived by the patients as high-risk features for increased risk of SARS-Cov-2 infection and more severe disease. Fifty-nine patients (44%) believed that their follow-up was influenced by the pandemic and only 58.8% felt that they had the opportunity to discuss their therapeutic options with their doctor. Sixty-three patients (46.0%) were working from home during the pandemic, although this decision was related to IBD and immunosuppressive therapy in only 36.5 and 39.7% of the cases, respectively. Areas where care could have been improved during the pandemic were identified by patients, namely enhancement of the communication with IBD professionals, conciliation of telemedicine with face-to-face appointments, and facilitation of the interaction between patients and employers. <b><i>Conclusion:</i></b> Most patients agreed that maintaining IBD remission is crucial, and only a minority of the patients stopped their treatment as per their own initiative. IBD status only had a small influence on patients’ professional activity during the COVID-19 outbreak, with most changes being related to the pandemic itself.

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.

BackgroundPsychological morbidity in inflammatory bowel disease is common with significant impact on quality of life and health outcomes, but factors which predict the development of psychological morbidity are unclear.AimTo undertake a systematic literature review of the predictors of psychological morbidity in patients with inflammatory bowel disease.MethodsElectronic searches for English-language articles were performed with keywords relating to psychological morbidity according to the Diagnostic and Statistical Manual of Mental Disorders IV and subsequent criteria, and inflammatory bowel disease; in MEDLINE, PsychInfo, Web of Science and EMBASE for studies published from January 1997 to 25 January 2019.ResultsOf 660 studies identified, seven met the inclusion criteria. All measured depression, with three also measuring anxiety. Follow-up duration was variable (median of 18 months range 6–96 months). Risk factors identified for development of psychological morbidity included physical factors: aggressive disease (HR 5.77, 95% CI 1.89 to 17.7) and greater comorbidity burden (OR 4.31, 95% CI 2.83 to 6.57) and psychological risk factors: degree of gratitude (r=−0.43, p<0.01) and parenting stress (R-change=0.03, F(1,58)=35.6, p<0.05). Age-specific risk was identified with young people (13–17 years) at increased risk.ConclusionsIdentifiable risks for the development of psychological morbidity in inflammatory bowel disease include physical and psychological factors. Further research is required from large prospective studies to enable early interventions in those at risk and reduce the impact of psychological morbidity.

Abstract Background During the early COVID-19 pandemic, the British Society of Gastroenterology (BSG) developed a risk stratification grid to inform the United Kingdom (UK) government regarding strict social isolation, termed “shielding”. This advised inflammatory bowel disease (IBD) patients thought to be most clinically vulnerable to SARS-CoV-2 infection or severe COVID-19 outcomes, to stay at home and minimize face to face contact, even with household members. Those considered at highest risk included recent commencement of combination biologic and immunomodulator therapy, prednisolone ≥20mg/day, presence of comorbidities, age ≥70 years or clinically active disease in those receiving immunosuppression. Mesalazine was not considered to increase risk. An acknowledged limitation was an absence of COVID-19 risk data. This study sought to identify patient or IBD medication-related factors associated with severe outcomes from COVID-19. Methods PREPARE-IBD was a multi-centre observational United Kingdom (UK) cohort study including adult IBD patients (≥18 years) diagnosed with COVID-19 by PCR between 1st March 2020 and 31st August 2020. The primary outcome was severe COVID-19 defined as requirement for intensive care admission, invasive ventilation or death. We tested associations of severe outcomes with medications and other covariates using multiple logistic regression. Results 211 patients were included from 60 UK centres. 56 of 211 patients (26.5%) met the primary outcome. Severe COVID-19 was more common in ulcerative colitis relative to Crohn’s disease patients (33.9% [37/109] vs. 18.6% [16/86], p=0.018). Shortness of breath, nausea and vomiting were more common with severe COVID-19 (p&lt;0.001 and p=0.023 respectively). Multivariable analysis identified co-morbidities and age as associated with severe COVID-19 outcomes; odds ratio (OR [95% CI]) 1.68 (1.23-2.35) for each co-morbidity, and an OR 1.03 (1.00-1.05) with each successive year of age. Neither clinically active IBD (OR 0.58 [0.26-1.26]), non-white ethnicity (OR 1.98 [0.92-4.28]), nor prednisolone use (OR 2.42 [0.47-11.26]) were associated with increased risk. On multivariable analysis, mesalazine was associated with severe COVID-19 outcomes (OR 2.03 [1.01-4.12]). Univariable analysis identified biologics and thiopurines as protective (OR 0.38 [0.15-0.87] and 0.32 [0.092-0.86] respectively). On multivariable analysis no association of severe COVID-19 outcomes with thiopurine or biologic exposure was seen. Conclusion Our data provide reassurance for the continued evidence-based use of corticosteroids, immunomodulators and biologic therapies in IBD during the ongoing COVID-19 pandemic, and is consistent with an as yet unexplained association between mesalazine use and severe COVID-19 outcomes.

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.
