AbstractIntroductionThere are concerns regarding the effectiveness and safety of SARS‐CoV‐2 vaccine in inflammatory Bowel Disease (IBD) patients. This systematic review and meta‐analysis comprehensively summarises the available literature regarding the safety and effectiveness of SARS‐CoV‐2 vaccine in IBD.MethodsThree independent reviewers performed a comprehensive review of all original articles describing the response of SARS‐CoV‐2 vaccines in patients with IBD. Primary outcomes were (1) pooled seroconversion rate SARS‐CoV‐2 vaccination in IBD patients (2) comparison of breakthrough COVID‐19 infection rate SARS‐CoV‐2 vaccination in IBD patients with control cohort and (3) pooled adverse event rate of SARS‐CoV‐2 vaccine. All outcomes were evaluated for one and two doses of SARS‐CoV‐2 vaccine. Meta‐regression was performed. Probability of publication bias was assessed using funnel plots and with Egger’s test.ResultsTwenty‐one studies yielded a pooled seroconversion rate of 73.7% and 96.8% in IBD patients after one and two doses of SARS‐CoV‐2 vaccine respectively. Sub‐group analysis revealed non‐statistically significant differences between different immunosuppressive regimens for seroconversion. Meta‐regression revealed that the vaccine type and study location independently influenced seroconversion rates. There was no statistically significant difference in breakthrough infection in IBD patients as compared to control after vaccination.ConclusionIn summary, the systematic review and meta‐analysis suggest that SARS‐CoV‐2 vaccine is safe and effective in IBD patients.

Abstract Background Colectomy is the curative management for ulcerative colitis (UC). Multiple studies have reported racial disparities for colectomy before the advent of anti-TNF alpha agents. The aim of this study was to describe racial and geographic differences in colectomy rates among hospitalized patients with UC after anti-TNF therapy was introduced. Methods We examined all patients discharged from the hospital between 2010 and 2014 with a primary diagnosis of UC or of complications of UC. The data were evaluated for race and colectomy rates among the hospitalized patients with UC. Results The unadjusted national colectomy rate among hospitalized patients with UC between 2010 and 2014 was 3.90 per 1000 hospitalization days (95% confidence interval, 3.72-4.08). The undajusted colectomy rates in African American (2.33 vs 4.35; P < 0.001) and Hispanic patients (3.99 vs 4.35; P ≤ 0.009) were considerably lower than those for White patients. After adjustment for confounders, the incidence rate ratio for African American as compared to White patients was 0.43 (95% confidence interval, 0.32-0.58; P < 0.001). Geographic region of the United States also showed significant variation in colectomy rates, with western regions having the highest rate (4.76 vs 3.20; P < 0.001). Conclusions Racial and geographical disparities persist for the rate of colectomy among hospitalized patients with UC. The national database analysis reveals that colectomy rates for hospitalized African American and Hispanic patients were lower than those for White patients. Further studies are important to determine the social and biologic foundations of these disparities.
