Lay Summary It is unknown if immune checkpoint inhibitor therapy increases risk of pouch-related complications in patients with inflammatory bowel disease after ileal-pouch anal anastomosis. In our study, pembrolizumab therapy was not associated with significant gastrointestinal immune-related adverse events or pouch-related complications.

Abstract Introduction The COVID-19 pandemic caused by SARS-CoV-2 continues to result in significant morbidity and mortality on a global scale. Prior studies have examined the effectiveness of non-COVID vaccines in setting of sleep disturbances. This study evaluated data from a large national database to examine the relationship between the risk of breakthrough COVID-19 infections in patients with certain sleep related disturbances. Methods Real-time search and analysis using the TriNetX platform to evaluate risk of COVID-19 breakthrough infections (BTI) for patients having ICD-10 diagnoses relating to insomnia, circadian rhythm disorders, and inadequate sleep. The sleep disorder and control cohorts underwent propensity matching including factors for age, gender, race, ethnicity, and multiple co-morbid conditions. Results Of 24,720 patients identified as having a sleep disturbance relating to insomnia, circadian rhythm disorder, or inadequate sleep, 815 (3.2%) were found to have a developed a BTI. There was a significant increased risk of BTI noted between the sleep disorder and control cohorts (adjusted odds ratio (aOR) of 1.40, 95% confidence interval (CI) of 1.23-1.58). Subgroup analysis showed an elevated risk for BTI receiving two doses (aOR 1.53, 95% CI 1.24 – 1.89) versus three doses (aOR 1.45, 95% CI 1.24 – 1.69). Patients with the sleep disturbance were not found to be at an increased risk of hospitalization, intubation, death, or composite outcome of death and intubation. Conclusion The presence of having a diagnosis of insomnia, circadian rhythm disorder, or inadequate sleep was associated with increased risk of COVID-19 breakthrough infection. Support (if any)

Abstract: Background and Aims The BNT162b2 and mRNA-1273 COVID-19 vaccines are efficacious in patients with inflammatory bowel disease; but there is a lack of data examining if holding immunosuppressive therapy around vaccination improves immune response. We studied the effect of holding IBD medications around the time of vaccination on antibody response and breakthrough COVID-19 infection. Methods Partnership to Report Effectiveness of Vaccination in populations Excluded from iNitial Trials of COVID is a prospective cohort of individuals with IBD receiving COVID-19 vaccination. Quantitative measurement of anti-receptor binding domain IgG antibodies to SARS-CoV-2 was performed 8 weeks after completing a vaccination series. Results A total of 1854 patients were included; 59% were on anti-tumour necrosis factor [TNF] [10% of these on combination therapy], 11% on vedolizumab, and 14% on ustekinumab; 11% of participants held therapy before or after vaccine administration for at least 2 weeks. Antibody levels were similar in participants continuing versus holding anti-TNF monotherapy before or after the second vaccine [BNT162b2: 10 μg/mL vs 8.9 μg/mL; mRNA-1273: 17.5 μg/mL vs 14.5 μg/mL]. Comparable results were seen in those on combination therapy. Antibody titres in those on ustekinumab or vedolizumab were higher compared with anti-TNF users, but there was no significant difference if the drug was held or continued [BNT162b2: 22.5 μg/mL vs 23 μg/mL; mRNA-1273: 88 μg/mL vs 51 μg/mL]. Holding therapy was not associated with decreased rate of COVID-19 infection compared with those not holding therapy [BNT162b2: 28% vs 29%; mRNA-1273: 19% vs 31%]. Conclusion We recommend continuing IBD medications while receiving mRNA COVID-19 vaccination without interruption.

INTRODUCTION: Use of the electronic health record (EHR) has become increasingly widespread. Higher EHR burden is associated with burnout, but this has not been specifically investigated among gastroenterology (GI) providers. METHODS: We retrospectively collected measures of EHR use for outpatient GI providers during a 6-month period. We compared metrics across provider sex, subspecialty, and training (physicians vs nonphysician providers [NPPs]). RESULTS: Data collected represented more than 16,000 appointments from 41 providers across the Division of Gastroenterology and Hepatology. Inflammatory bowel disease (IBD) and hepatology specialists spent more time per appointment in the EHR, clinical review, and outside regular hours compared with other subspecialists. NPPs spent more EHR time than physicians. DISCUSSION: IBD and hepatology specialists and NPPs may have disproportionally high EHR burden. More work is needed to understand differences in provider workload to combat burnout.

Abstract Background Despite the growing therapeutic armamentarium, at least half of the patients with Crohn’s disease will require surgery during their lifetime. Current evidence for the prevention and treatment of postoperative Crohn’s disease supports the use of anti-tumor necrosis factor agents with limited data about the use of the newer biologics, vedolizumab and ustekinumab. Methods We performed a systematic review of available data to determine the efficacy of the newer biologics in the management of postoperative Crohn’s disease. We included noncomparative and comparative studies. The main outcomes of interest were clinical and endoscopic postoperative recurrence rates. Results The search strategy identified 1231 citations, with 32 eligible for review. Several studies showed that the postoperative Crohn’s disease recurrence rates with the use of the newer biologics were comparable to previously published results with the use of anti-tumor necrosis factor agents, while other studies failed to show their efficacy. It is important to note that the studies were heterogeneous and included a relatively small sample size, making it difficult to draw a definite conclusion about the efficacy of the newer biologics in the management of postoperative Crohn’s disease. Conclusion The newer biologics do play a role in the management of postoperative Crohn’s disease. After our review, we proposed an updated algorithm on the role of newer biologics in the approach to patients with postoperative Crohn’s disease. Yet, until we have better-designed studies, their definite positioning remains to be determined.

Common variable immunodeficiency (CVID) is the most common symptomatic primary immunodeficiency. It is characterized by impaired B-cell differentiation. Although patients can be diagnosed with CVID anytime during their lifetime, most patients have symptoms for 5–9 years before their diagnosis. The diagnosis of CVID starts with a detailed history focusing on the infectious and noninfectious manifestations of the disease. In patients who are suspected to experience CVID, quantitative immunoglobulins (Ig) should be checked to confirm the diagnosis. IgG should be at least 2 times less than the age-specific SD along with either a low IgA or IgM and with evidence of impaired vaccine response. CVID is usually associated with infectious and/or noninfectious conditions, the latter of which can be inflammatory, autoimmune, lymphoproliferative, or malignant, among other manifestations. Ig therapy has positively affected the disease course of patients with infectious complications but has limited effect on the noninfectious manifestations because the noninfectious complications are related to immune dysregulation involving B cells and T cells rather than primarily due to antibody deficiency. When the gastrointestinal (GI) system is involved, patients with CVID may display signs and symptoms that mimic several GI conditions such as celiac disease, pernicious anemia, or inflammatory bowel diseases. The inflammatory bowel disease–like condition is usually treated with steroids, 5-aminosalicylates, thiopurines, or biologic agents to control the inflammation. In this review, the clinical presentations, diagnostic considerations, and therapeutic options for GI manifestations of CVID will be discussed to facilitate the individualized management of these often-complex patients.
