Abstract Background Tixagevimab and cilgavimab (Evusheld) are 2 fully human monoclonal antibodies that received emergency-use authorization on December 21, 2021, for pre-exposure prophylaxis of coronavirus disease 2019 (COVID-19) in patients who are moderate–severely immunocompromised. The real-world efficacy of Evusheld in patients with inflammatory bowel disease (IBD) is not known. Methods We conducted a retrospective cohort study using TriNetX, a multi-institutional database in patients with IBD who received Evusheld compared to patients with IBD who did not receive Evusheld (12.1.2021–10.28.2022). The primary outcome was to assess the risk of COVID-19 within 6 months. One-to-one propensity score matching (PSM) was performed for demographic parameters, comorbid conditions, IBD medications, and history of COVID-19. Risk was expressed as adjusted odds ratio (aOR) with 95% confidence interval (CI). Results Four hundred and eight patients (0.19%) with IBD received Evusheld (mean age 58.6 ± 15.4 years old, female 47.7%) during the study period. After PSM, there was no difference in the risk (aOR 0.88, 95% CI, 0.33–2.35) of COVID-19 in the Evusheld cohort compared to the IBD control cohort. No patients required ICU care or intubation/respiratory support or were deceased in the Evusheld cohort. Conclusions Our study did not show that Evusheld decreases the risk of COVID-19 in patients with IBD. Prevention of moderate–severe COVID-19 in these patients should focus on vaccination strategies and early COVID-19 therapies.

Background: Tumor necrosis factor (TNF-α) inhibitors and the α4β7 integrin antagonist, vedolizumab, have been investigated as treatment options for patients with steroid-refractory microscopic colitis. Aims: To evaluate the benefit of vedolizumab and TNF-α inhibitors in patients with steroid-refractory microscopic colitis. Methods: Retrospective studies and case series involving patients with steroid-refractory MC who either received vedolizumab, adalimumab, or infliximab were eligible for inclusion. Pooled proportional meta-analyses were used to calculate the rate of clinical remission at induction, clinical response, maintenance of remission, histologic remission, and overall medication related adverse effects. Statistical analysis was performed in R using the metafor and meta packages. Results: A total of 14 studies involving 164 patients were included. Pooled analysis showed a clinical remission rate of 63.5% [95% CI (0.483; 0.776), I 2 =43% P =0.08], 57.8% [95% CI (0.3895; 0.7571), I 2 =0%, P =0.7541], and 39.3% [95% CI (0.0814; 0.7492), I 2 =66%, P =0.02] for vedolizumab, infliximab, and adalimumab, respectively. The maintenance of remission rates were 65.9% [95% CI (0.389; 0.889), I 2 =67%, P =0.02], 45.3% [95% CI (0.1479; 0.7747), I 2 =0%, P =0.36] and 32.5% [95% CI (0.000; 0.8508), I 2 =53%, P =0.14] in patients who received vedolizumab, infliximab, and adalimumab, respectively. Rate of biological-related adverse events warranting discontinuation of therapy was 12.2%, 32.9%, and 23.0% for the vedolizumab, infliximab, and adalimumab groups, respectively. Conclusion: Vedolizumab and anti-TNF-α agents demonstrated a clinical benefit in the treatment of steroid-refractory microscopic colitis and with a tolerable safety profile. Future randomized controlled trials are needed to compare vedolizumab with TNF-α inhibitors and examine treatment effect on patients’ quality of life.

Abstract Background There is evidence that SARS-CoV2 infection can increase the risk of herpes zoster (HZ) in the general population. However, the risk in patients with inflammatory bowel disease (IBD) is not known. Methods The TriNetX database was utilized to conduct a retrospective cohort study in patients with IBD after SARS-CoV2 infection and patients without a SARS-CoV2 infection (IBD control cohort). The primary outcome was to evaluate the risk of HZ between the 2 cohorts. One-to-one (1:1) propensity score matching was performed for demographic parameters, HZ risk factors and IBD medications between the 2 cohorts. Adjusted odds ratio (aOR) with 95% confidence interval (CI) were calculated. Results After propensity score matching, patients with IBD with a SARS-CoV2 infection were at an increased risk for HZ (aOR, 2.16; 95% CI, 1.53-3.04) compared with IBD control cohort in the pre-COVID-19 vaccine era. There was no difference in the risk (aOR, 0.87; 95% CI, 0.44-1.75) of a composite outcome of HZ complications (hospitalization, post-herpetic neuralgia, and neurologic complications) between the 2 cohorts. The IBD SARS-CoV2 cohort was also at an increased risk for HZ (aOR, 3.04; 95% CI, 1.48-6.24) compared with IBD control cohort in the postvaccine era. However, the risk of HZ in the postvaccine era was decreased (aOR, 0.45; 95% CI, 0.27-0.76) compared with IBD SARS-CoV2 cohort in the prevaccine era. Conclusions Our study showed that SARS-CoV2 infection is associated with an increased risk of HZ in patients with IBD.

Introduction and Aim: A growing body of evidence suggests a negative impact of obesity on the disease activity of inflammatory bowel disease (IBD). The primary aim of the study was to evaluate disease outcomes of IBD in patients after bariatric surgery (BS). Methods: Patients with IBD and morbid obesity who underwent BS were compared with patients with IBD and morbid obesity without BS in a retrospective, propensity-score matched cohort study using TriNetX, a multi-institutional database. The primary aim was to assess the 2-year risk of a composite of disease-related complications, which included intravenous steroid use or IBD-related surgery. Risk was expressed as adjusted odds ratios (aOR) with 95% confidence intervals (CI). Results: In all, 482 patients (3.4%) with IBD and morbid obesity underwent BS (mean age 46.9±11.2 y old, mean BMI 42.1±7.72 kg/m2, Crohn’s disease 60%). After propensity-score matching, the BS cohort had a lower risk (aOR 0.31, 95% CI 0.17-0.56) of a composite of IBD-related complications compared with the control cohort. After propensity-score matching, the BS cohort with sleeve gastrectomy had a decreased risk (aOR 0.45, 95% CI 0.31-0.66) of a composite of IBD-related complications. There was no difference in the risk (aOR 0.77, 95% CI 0.45–1.31) of a composite of IBD-related complications between the BS cohort with Roux-en-Y gastric bypass (RYGB) compared with the control cohort. Conclusion: Sleeve gastrectomy but not Roux-en-Y gastric bypass is associated with improved disease-specific outcomes in patients with IBD and morbid obesity.
