Lay SummaryWe demonstrate low rates of breakthrough coronavirus disease 2019 (COVID-19) infection and mild course of illness following severe acute respiratory syndrome coronavirus 2 vaccination in a large cohort of inflammatory bowel disease patients. Residence in southern United States and lower median anti-receptor binding antibody level were associated with development of COVID-19.

Abstract Background Fecal microbiota transplantation (FMT) has been investigated as a treatment option for patients with inflammatory bowel disease with controversial results. We sought to perform a systematic review and meta-analysis to evaluate the benefit of FMT in patients with ulcerative colitis. Methods Double-blind randomized controlled trials (RCTs) including adult patients with active ulcerative colitis who received either FMT or placebo were eligible for inclusion. Outcomes of interest included the rate of combined clinical and endoscopic remission, endoscopic remission or response, clinical remission or response, and specific adverse events. The results were pooled together using Reviewer Manager 5.4 software. Publication bias was assessed using the Egger’s test. Results Six RCTs involving 324 patients were included. Our findings demonstrate that compared with placebo, FMT has significant benefit in inducing combined clinical and endoscopic remission (odds ratio, 4.11; 95% confidence interval, 2.19-7.72; P < .0001). Subgroup analyses of influencing factors showed no differences between pooled or single stool donors (P = .71), fresh or frozen FMT (P = .35), and different routes or frequencies of delivery (P = .80 and .48, respectively). Pre-FMT antibiotics, bowel lavage, concomitant biologic therapy, and topical rectal therapy did not affect combined remission rates (P values of .47, .38, .28, and .40, respectively). Clinical remission or response and endoscopic remission or response were significantly higher in patients who received FMT compared with placebo (P < .05) without any differences in serious or specific adverse events. Conclusions FMT demonstrated a clinical and endoscopic benefit in the short-term treatment of active ulcerative colitis, with a comparable safety profile to placebo. Future RCTs are required to standardize study protocols and examine data on maintenance therapy.

AbstractMalnutrition is a very common and often underrecognized condition among patients with inflammatory bowel diseases (IBD). This is most commonly due to increased nutritional requirements and gastrointestinal losses, along with reduced oral intake. Screening for malnutrition is an essential component of managing both inpatients and outpatients with IBD. Although enteral nutrition is the preferred route of supplementation, parenteral nutrition (PN) remains an important strategy and should be considered in certain situations, such as cases with short-bowel syndrome, high-output intestinal fistula, prolonged ileus, or small-bowel obstruction. Appropriate use of PN is critical in order to prevent associated complications. This review addresses the common indications for use of PN, the composition of PN, and the possible complications encountered with PN use, as well as scenarios of inappropriate PN use among patients with IBD. A clinical management algorithm for utilizing PN among patients with IBD is proposed in this review.

AbstractBackgroundOwing to the use of immunosuppressive agents, patients with inflammatory bowel disease (IBD) have an increased risk of vaccine preventable diseases, including infection with hepatitis B virus (HBV). Heplisav-B, an FDA-approved vaccine, is more effective (90% to 100%) than Engerix-B (70.5% to 90.2%) at inducing immunity to HBV in clinical studies. Available data on efficacy of Heplisav-B vaccine in patients with IBD are limited.MethodsThis retrospective observational study included patients age 18 years and older with ulcerative colitis (UC) or Crohn’s disease (CD) who received 1 or 2 doses of Heplisav-B vaccine and had postvaccination serologic testing. Prior to immunization, all participants were seronegative for HBsAb antibodies (HBsAb) measured as <10 IU/mL. Postvaccination HBsAb of ≥10 IU/mL was considered successful vaccination. Patient demographics, disease characteristics, and medications were abstracted.ResultsOne hundred six patients were included in the analysis. Median age was 43 years, and 44 (42%) were female. Thirty-nine patients (37%) had UC, whereas 67 (63%) had CD. Eighty-three patients (78.3%) had active immunity after vaccination with Heplisav-B, with median postvaccination HBsAb levels of 114 IU/L. Patients with chronic obstructive pulmonary disease, chronic kidney disease, diabetes mellitus, immunomodulator use, or those on 2 or more of immunosuppressive medications were less likely to respond to Heplisav-B, though these findings were not statistically significant on a multivariate analysis aside from chronic kidney disease.ConclusionsHeplisav-B, a 2-dose vaccine, is an effective vaccine for HBV in patients with IBD. In our study, its overall efficacy (78.3%) is greater than that reported for the presently available 3-dose vaccination (Engerix) in patients with IBD.

Lay Summary Herein, we evaluated the humoral immunogenicity of a third coronavirus disease 2019 messenger RNA vaccine dose in patients with inflammatory bowel diseases. All patients displayed a humoral immune response, and median antibody concentrations were higher after the third dose than after completion of the 2-dose series.

Lay Summary Biosimilar medications have the potential to significantly reduce the cost of treatment in patients with inflammatory bowel disease. Observational studies have shown similar efficacy and safety of biosimilars to biologic reference products. Shared decision-making is crucial to the successful implementation of these agents.

Abstract Background Microscopic colitis (MC) is suspected to result from increased immune activity in gut mucosa. Immune checkpoint inhibitors (ICIs) treat cancer by activating the immune system, and further investigation is needed regarding their role in the development of MC. Methods A retrospective case series investigated cases of endoscopically and histologically confirmed MC developing after administration of ICIs. Clinical notes and medication administration records were reviewed for demographics, symptom duration, and treatment response. Results Nineteen cases of de novo MC were identified, with 95% of cases requiring steroid treatment, 53% presenting with hospitalization, and colitis-related mortality in 1 individual. Symptom onset occurred a median of 160 days after initiation of ICI therapy and 53 days after their most recent dose of therapy. Patients had a median of 125 days of symptoms, and ICI therapy was held in 70% of individuals due for treatment. Conclusions MC can develop after ICI administration, and presents with severe symptoms, often requiring hospitalization and steroid treatment. In certain individuals this can require a prolonged treatment course of steroid therapy or immunomodulators. Individuals developing diarrhea after ICI therapy warrant thorough workup including endoscopy and rapid treatment initiation given the disease severity observed in this series.

Abstract Background and study aims Splenic injury (SI) during colonoscopy is an underappreciated adverse event. Our aim was to examine the occurrence and outcomes of patients who developed SI after inpatient colonoscopy using a nationwide dataset. Patients and methods Retrospective, observational study using the National Inpatient Sample (NIS) between 2012 and 2018. All patients with ICD9/10CM procedural codes for colonoscopy with or without SI were included. The primary outcome was the association between SI and inpatient colonoscopy. Secondary outcomes were inpatient morbidity, mortality, resource utilization, splenectomy rates, hospital length of stay and total hospital costs and charges. Comparative analyses were performed between patients with and without SI. Multivariate regression analyses were utilized. Results A total of 2,258,040 of inpatient colonoscopies were included. Of these, 240 had associated SI and 25 patients required splenectomy (10.4 %). The incidence of colonoscopy-associated SI remained relatively stable between 2012 and 2018 (0.033 % versus 0.020 %, respectively). The mean age of patients with and without SI was 63.7 and 64.1 years, respectively. The occurrence of SI was calculated as 10.63 cases per 100,000 inpatient colonoscopies. Patients who had associated SI displayed significantly higher odds of inpatient mortality (aOR: 14.45) and ICU stay (aOR: 10.11) compared to those without SI. Conclusions Splenic injury confers significantly higher odds of inpatient mortality, and resource utilization. The incidence of SI related to colonoscopy remained stable during the study period. Although uncommon, SI should be considered when encountering patients with abdominal pain after colonoscopy.

Abstract Background Active inflammatory bowel disease (IBD) at conception is associated with adverse pregnancy outcomes. Published literature suggests that almost a quarter of women with IBD do not use any form of contraception putting them at risk of unplanned pregnancy. Recent guidelines emphasise the importance of antenatal care in IBD patients, but contraception counselling and risk assessment are not addressed. Our aim was to explore the contraceptive knowledge, attitudes and preferences of women with IBD. Methods A 34-item questionnaire was prospectively administered to 245 consecutive female IBD patients aged 18–45 attending gastroenterology clinics. Disease control was measured using the validated IBD Control questionnaire, and contraceptive preferences assessed by the Contraceptive Features Survey. Results Of the 245 participants (see table 1), mean disease duration was 6.5 years, median IBD control score was 16.9 (range 0- 26), and 152 (62%) respondents had previously been pregnant. Almost three quarters of respondents (n=176) reported currently using contraception, and 41 (17%) were using highly effective contraceptives. The most commonly used contraceptives were oral birth control pills (27%) and barrier methods (18%). Participants who identified as Caucasian (74%) were more likely than those who identified as Asian (37%) to use contraception (p=0.0009). Patients who did not plan to conceive in the future were more likely to use contraception (p=0.0365). However, of the 58% (n=143) who had either no plans to conceive in the future or were unsure, 23% were not using any form of contraception, and 83% were not using a highly effective contraceptive. Current biologic therapy was significantly associated with highly effective contraceptive use (p=0.0275). Contraceptive features most important to women were effectiveness (78%), ease of use (76%), few or no side effects (68%) and not detracting from sexual enjoyment (65%). Only 25% patients (n=61) recalled discussing reproductive issues with their IBD clinician, however, 86% stated they would feel comfortable having this discussion. Women wished to receive family planning counselling from their IBD nurse (81%), General practitioner (77%), IBD doctor (68%), and gynaecologist (47%). Conclusion A quarter of patients in our cohort were not using any contraception and the majority were not using a highly effective form potentially increasing their risk of unplanned or mistimed pregnancy. Participants desired a contraceptive that was effective, easy to use and with minimal side effects. Our findings reflect the need for further studies to improve informed decision making with contraceptive counselling, to improve the overall quality of care for women with IBD.
