SummaryBackgroundThere is limited real‐world data on comparative effectiveness of different biologic or small molecule agents as second‐line therapies in patients with ulcerative colitis (UC) with prior exposure to a tumour necrosis factor inhibitor (TNFi).MethodsWe conducted a retrospective cohort study using TriNetX, a multi‐institutional database to assess the efficacy of tofacitinib, vedolizumab and ustekinumab in patients with ulcerative colitis (UC) with prior exposure to a TNFi. Failure of medical therapy was defined as a composite outcome of intravenous steroids or colectomy within 2 years. One‐to‐one propensity score matching was performed for demographics, disease extent, mean haemoglobin, C‐reactive protein, albumin and calprotectin, prior IBD medications and steroid use between cohorts.ResultsAmong 2141 patients with UC and prior exposure to TNFi, 348 (16.2%), 716 (33.4%) and 1077 (50.3%) were switched to tofacitinib, ustekinumab and vedolizumab, respectively. After propensity‐score matching, there was no difference in the composite outcome (aOR: 0.77, 95% CI: 0.55–1.07) but higher risk of colectomy (aOR: 2.69, 95% CI: 1.31–5.50) in the tofacitinib cohort than the vedolizumab cohort. There was no difference in the risk of composite outcome (aOR: 1.29, 95% CI: 0.89–1.86) but higher risk of colectomy (aOR: 2.63, 95% CI: 1.24–5.58) in the tofacitinib cohort than the ustekinumab cohort. The vedolizumab cohort had a higher risk of composite outcome (aOR: 1.67, 95% CI: 1.29–2.16) than the ustekinumab cohort.ConclusionUstekinumab might be the preferred second‐line therapy over tofacitinib and vedolizumab in patients with UC that were previously exposed to a TNFi.

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.

Abstract Background and Aims Technological advances have provided innovative, adaptive, and responsive models of care for inflammatory bowel diseases [IBD]. We conducted a systematic review to compare e-health interventions with standard care in management of IBD. Methods We searched electronic databases for randomised, controlled trials [RCT] comparing e-health interventions with standard care for patients with IBD. Effect measures were standardised mean difference [SMD], odds ratio [OR], or rate ratio [RR], calculated using the inverse variance or Mantel–Haenszel statistical method and random-effects models. Version 2 of the Cochrane tool was used to assess the risk of bias. The certainty of evidence was appraised with the GRADE framework Results Fourteen RCTs [n = 3111; 1754 e-health and 1357 controls] were identified. The difference in disease activity scores (SMD 0.09, 95% confidence interval [CI]: -0.09-0.28) and clinical remission (odds ratio [OR] 1.12, 95% CI: 0.78-1.61) between e-health interventions and standard care were not statistically significant. Higher quality of life [QoL] [SMD 0.20, 95% CI: 0.05-0.35) and IBD knowledge [SMD 0.23, 95% CI: 0.10-0.36] scores were noted in the e-health group, and self-efficacy levels [SMD -0.09, 95% CI: -0.22-0.05] were comparable. E-health patients had fewer office [RR 0.85, 95% CI: 0.78-0.93] and emergency [RR 0.70, 95% CI: 0.51- 0.95] visits, with no statistically significant difference in endoscopic procedures, total health care encounters, corticosteroid use, and IBD related hospitalisation or surgery. The trials were judged to be at high risk of bias or to have some concerns for disease remission. The certainty of evidence was moderate or low. Conclusion E-health technologies may have a role in value-based care in IBD.

Abstract Aim There are limited data on the impact of 2 vs 3 doses of COVID-19 vaccine in patients with inflammatory bowel disease (IBD). The primary aim of the study was to assess the efficacy of COVID-19 vaccine based on number of administered doses in patients with IBD. Methods We conducted a retrospective cohort study using TriNetX, a multi-institutional database to compare patients with IBD who received 1, 2, or 3 doses of BNT162b2 or mRNA-1273 to unvaccinated IBD patients (1.1.2020-7.26.2022) to assess the risk of COVID-19 after 1:1 propensity score matching. We also evaluated the impact of vaccine on a composite of severe COVID-19 outcomes including hospitalization, intubation, intensive care unit care, acute kidney injury, or mortality. Results After propensity score matching, vaccinated patients with 2 (adjusted OR [aOR], 0.8; 95% confidence interval [CI], 0.6-0.9) and 3 doses (aOR, 0.7; 95% CI, 0.5-0.9) were found to have a lower risk of COVID-19 compared with unvaccinated patients. Vaccinated patients with IBD had a lower risk of severe COVID-19 outcomes (aOR, 0.7; 95% CI, 0.6-0.9) compared with unvaccinated patients. There was no difference in the risk of COVID-19 in IBD patients with 2 compared with 3 doses (aOR, 0.97; 95% CI, 0.7-1.3). However, IBD patients with 2 doses were at an increased risk for hospitalization due to COVID-19 (aOR, 1.78; 95% CI, 1.02-3.11) compared with those that received 3 doses. Conclusion Vaccinated patients with IBD had a lower risk of severe COVID-19 outcomes compared with unvaccinated patients. A third dose of COVID-19 vaccine compared with 2 doses decreases the risk of hospitalization but not breakthrough infection in patients with IBD.

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.

INTRODUCTION: Children with inflammatory bowel disease (IBD) may respond differently to COVID-19 immunization as compared with healthy children or adults with IBD. Those younger than 12 years receive a lower vaccine dose than adults. We sought to describe the safety and humoral immune response to COVID-19 vaccine in children with IBD. METHODS: We recruited children with IBD, ages 5–17 years, who received ≥ 2 doses of the BNT162b2 vaccine by a direct-to-patient outreach and at select sites. Patient demographics, IBD characteristics, medication use, and vaccine adverse events were collected. A subset of participants had quantitative measurement of anti-receptor binding domain IgG antibodies after 2-part immunization. RESULTS: Our study population included 280 participants. Only 1 participant required an ED visit or hospitalization because of an adverse event. Of 99 participants who underwent anti-receptor binding domain IgG antibody measurement, 98 had a detectable antibody, with a mean antibody level of 43.0 μg/mL (SD 67) and a median of 22 μg/mL (interquartile range 12–38). In adjusted analyses, older age ( P = 0.028) and antitumor necrosis factor monotherapy compared with immunomodulators alone ( P = 0.005) were associated with a decreased antibody level. Antibody response in patients treated with antitumor necrosis factor combination vs monotherapy was numerically lower but not significant. DISCUSSION: Humoral immune response to COVID-19 immunization in children with IBD was robust, despite a high proportion of this pediatric cohort being treated with immunosuppressive agents. Severe vaccine-related AEs were rare. Overall, these findings provide a high level of reassurance that pediatric patients with IBD respond well and safely to SARS-CoV-2 vaccination.

Abstract Background Much of our understanding about the natural history of pouch-related disorders has been generated from selected populations. We designed a geographically diverse, prospective registry to study the disease course among patients with 1 of 4 inflammatory conditions of the pouch. The primary objectives in this study were to demonstrate the feasibility of a prospective pouch registry and to evaluate the predominant treatment patterns for pouch-related disorders. Methods We used standardized diagnostic criteria to prospectively enroll patients with acute pouchitis, chronic antibiotic-dependent pouchitis (CADP), chronic antibiotic refractory pouchitis (CARP), or Crohn’s disease (CD) of the pouch. We obtained detailed clinical and demographic data at the time of enrollment, along with patient-reported outcome (PRO) measures. Results We enrolled 318 patients (10% acute pouchitis, 27% CADP, 12% CARP, and 51% CD of the pouch). Among all patients, 55% were on a biologic or small molecule therapy. Patients with CD of the pouch were more likely to use several classes of therapy (P < .001). Among patients with active disease at the time of enrollment, 23% with CARP and 40% with CD of the pouch were in clinical remission at 6 months after enrollment. Conclusions In a population where most patients had refractory inflammatory conditions of the pouch, we established a framework to evaluate PROs and clinical effectiveness. This infrastructure will be valuable for long-term studies of real-world effectiveness for pouch-related disorders.

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.

INTRODUCTION: Limited guidance exists for the postdischarge care of patients with ulcerative colitis hospitalized for moderate-severe flares. METHODS: RAND methodology was used to establish appropriateness of inpatient and postdischarge steroid dosing, discharge criteria, follow-up, and postdischarge biologic or small molecule initiation. A literature review informed on the panel's voting, which occurred anonymously during 2 rounds before and after a moderated virtual session. RESULTS: Methylprednisolone 40–60 mg intravenous every 24 hours or hydrocortisone 100 mg intravenous 3 times daily is appropriate for inpatient management, with methylprednisolone 40 mg being appropriate if intolerant of higher doses. It is appropriate to discharge patients once rectal bleeding has resolved (Mayo subscore 0–1) and/or stool frequency has returned to baseline frequency and form (Mayo subscore 0–1). It is appropriate to discharge patients on 40 mg of prednisone after observing patients for 24 hours in hospital to ensure stability before discharge. For patients being discharged on steroids without in-hospital biologic or small molecule therapy initiation, it is appropriate to start antitumor necrosis factor (TNF) therapy after discharge for anti-TNF-naive patients. For anti-TNF-exposed patients, it is appropriate to start vedolizumab or ustekinumab for all patients and tofacitinib for those with a low risk of adverse events. It is appropriate to follow up patients clinically within 2 weeks and with lower endoscopy within 4–6 months after discharge. DISCUSSION: We provide recommendations on the inpatient and postdischarge management of patients with ulcerative colitis hospitalized for moderate-severe flares.
