ABSTRACT Presented is a 76-year-old man with metastatic melanoma that was successfully treated with pembrolizumab, an immune checkpoint inhibitor (ICI). He underwent 20 months of ICI treatment without dose limiting side effects. Nearly 18 months after ICI discontinuation, the patient developed intermittent epigastric pain and diarrhea. Owing to mild symptoms, he was not immediately evaluated. Three years after ICI cessation, he was diagnosed with stricturing, jejunal Crohn's disease. He was treated with vedolizumab and displayed clinical and radiographic response to treatment. This case serves as an example of potential gastrointestinal-related, long-term autoimmune implications of ICI therapy, even in patients without acute side effects.

INTRODUCTION: Evidence-based recommendations for sexual practices regarding anoreceptive intercourse (ARI) do not exist in patients with inflammatory bowel diseases undergoing restorative proctocolectomy with ileal pouch anal anastomosis (IPAA). This study surveys providers on perspectives and attitudes related to sexual practices after IPAA. METHODS: We developed a 23-item survey and distributed it to providers caring for patients with inflammatory bowel diseases. RESULTS: 95% of providers believe that it is important to discuss sexual orientation or practices before IPAA, but only 27% routinely discuss this. 50% did not feel comfortable and 74% did not feel confident discussing ARI recommendations with patients who underwent or will undergo IPAA. DISCUSSION: Future interventions should aim to standardize recommendations regarding feasibility and time line to safe ARI after IPAA.

INTRODUCTION: We aimed to compare pregnancy outcomes of women with inflammatory bowel disease using biosimilar vs originator infliximab (IFX). METHODS: In a prospective cohort of pregnant women with inflammatory bowel disease, we collected characteristics, medications, pregnancy outcomes, and developmental milestones. We compared outcomes by IFX biosimilar or originator use via bivariate statistics. RESULTS: A total of 100 pregnant women on originator IFX and 20 on biosimilar IFX were included. There were no differences in pregnancy complications between groups (48% vs 35%, P = 0.29). Infant developmental milestones were comparable at 12 months. DISCUSSION: Biosimilar IFX is not associated with adverse pregnancy or infant outcomes.

Abstract Background and Aims Individuals with inflammatory bowel disease (IBD) experience a high symptom burden, including abdominal pain, fatigue, anxiety, depression, and sleep disturbances; yet, little is known regarding the relationship between sex and gender on symptoms. We sought to report symptom severity for cisgender men, cisgender women, and transgender and gender-diverse (TGD) individuals. In addition, we used network analysis to identify core symptoms and explore if symptoms and their relationships differ between cisgender men and cisgender women. Methods This was a cross-sectional study. We recruited adults with IBD online through ResearchMatch. Individuals responded to Patient-Reported Outcomes Measurement Information symptom questionnaires, as well as demographic and clinical questionnaires. Network analysis was used to identify the core symptoms driving the symptom structure. Results One-hundred and fifty-seven (63.3%) participants identified as cisgender women, 84 (33.9%) as cisgender men, and 7 (2.8%) as TGD. Cisgender men (M = 61.8) and TGD (M = 61.3) groups reported higher abdominal pain levels compared with cisgender women (M = 57.8; P = .02). Transgender and gender-diverse individuals reported higher depression levels (M = 64.8) compared with cisgender men (M = 56.7) and cisgender women (M = 54.4; P = .01). Using a network analysis approach, anxiety and fatigue emerged as core symptoms for the entire sample (clinically active and inactive disease), and among only those with active clinical disease. Fatigue was a top core symptom for cisgender women; anxiety emerged as a top core symptom for cisgender men. Conclusions This study highlights that fatigue and anxiety are core symptoms among individuals with IBD and demonstrates a potential sex and/or gender difference in core symptoms. Replication of this study is needed with further consideration of inclusion of TGD patients.
