Topical Steroids Are Effective and Safe in Patients With Eosinophilic Esophagitis Over a Median of 6.5 Years of Chronic Use.

GOALS: To determine long-term efficacy and safety of tCS for treatment of EoE. BACKGROUND: Maintenance therapy with topical corticosteroids (tCS) is recommended for eosinophilic esophagitis (EoE), but data for long-term use are still needed. STUDY: This retrospective cohort study assessed newly diagnosed patients with EoE who were treated with a tCS and had a follow-up endoscopy with biopsy after at least 5 years. Histologic symptomatic and endoscopic responses were extracted from medical records. Patients who did and did not have long-term tCS treatment were compared at baseline, and outcomes for patients were assessed at their last endoscopy while on tCS. RESULTS: Of 431 patients with EoE treated with tCS, 104 met inclusion criteria for long-term use. For patients with long-term tCS use, the median time (IQR) on tCS was 6.5 years (5.4 to 8.8 y). At the last endoscopy, 54% had histologic response (<15 eos/hpf), but those with excellent adherence had a histologic response of 64%. Endoscopic severity also decreased with improved adherence which was strongly associated with EREFS (1.7 vs. 2.8 vs. 4.0 for excellent, good, and poor adherence; P<0.001). Symptomatic response was 68% overall, but only 40% in those with poor adherence (P=0.07). Complications of taking tCS were uncommon (adrenal insufficiency: 1%; osteopenia: 1%; and esophageal candidiasis: 4% at final endoscopy). CONCLUSIONS: Long-term tCS (median 6.5 y) were generally effective, especially with better adherence, and also safe, with only rare serious complications. These data can be used to help patients make clinical decisions about chronic tCS use in EoE.

Assessing the Value of Histology and Anatomic Segment Evaluation Among Patients Undergoing Pouchoscopy.

BACKGROUND: The value of histologic assessment after ileal pouch-anal anastomosis (IPAA) has not been definitively determined. We evaluated the correlation between histology and endoscopic findings, as well as the proportion of patients with inflammation in areas beyond the pouch body on their initial pouchoscopy after IPAA. METHODS: In a retrospective cohort study, we evaluated patients who underwent IPAA for UC between 2012 and 2020 and subsequently underwent a pouchoscopy with routine biopsies of the pouch body, pre-pouch ileum, and rectal cuff. We compared endoscopic and histologic assessments in each location using χ2 testing and Spearman correlation, as well as the development of pouchitis and Crohn's-like disease of the pouch (CLDP) in longitudinal follow-up. RESULTS: Among 126 patients, the median time to pouchoscopy after IPAA was 384 days, with 82 patients (65%) having inflammation of the pouch body. Significantly more patients with pouch body inflammation had histologic inflammation compared with patients without pouch body inflammation (96% vs 22%, P < .001, r = 0.769). Additionally, 16 patients (13%) were found to have endoscopic inflammation of the pre-pouch ileum with corresponding histologic inflammation in 88%; of these, 31% later developed CLDP. In contrast, 13% of patients with no endoscopic inflammation displayed histologic inflammation, with none later developing CLDP. Forty-six percent of patients had rectal cuff inflammation (correlation with histologic inflammation r = 0.580). CONCLUSIONS: In our evaluation, the added benefit of histology in the presence of visible endoscopic inflammation for disease activity assessment scores is unclear. The prognostic value of histologic inflammation without endoscopic inflammation warrants a longitudinal study.

Endoscopic evaluation after ileal pouch-anal anastomosis should include anatomic areas beyond the pouch body, including the rectal cuff and the pre-pouch ileum. The added benefit of histology in the presence of visible inflammation when assessing disease activity is unclear.

Caregivers' Perspective on Successful Health Care Transition Outcomes for Adolescents and Young Adults With Special Health Care Needs.

PURPOSE: There is limited caregiver-reported evidence determining health care transition (HCT) outcomes for their adolescents/young adults with special health care needs (AYA-SHCN). A subcommittee of the International and Interdisciplinary Healthcare Transition Research Consortium aimed to identify multidimensional outcomes of a successful HCT among AYA-SHCN based on parents/caregivers' perspectives. METHODS: After literature review and expert interviews, a three-stage Delphi process identified HCT outcomes based on parents/caregivers' perspectives. Participants were parents/caregivers of patients attending the Victory Junction Therapeutic Camp and a nationally representative sample from Cint Healthcare Digital Solutions Platform. The cumulative 272 responses collected on a Health Insurance Portability and Accountability Act-compliant web-based engine (Qualtrics) rated potential HCT outcomes by level of importance on a Likert scale from 1 (not important) to 9 (very important) and narrowed in subsequent iterations. RESULTS: The Delphi process included 127 (Stage 1), 82 (Stage 2), and 63 (Stage 3) parents/caregivers. The initial 25 HCT outcomes were narrowed to 13, across four major domains: coping/satisfaction, behavioral, structural, and HCT/healthcare-focused outcomes. The top outcome was "My child takes their medications as prescribed." Several traditionally considered important outcomes for HCT were eliminated. DISCUSSION: Thirteen HCT outcomes for AYA-SHCN were identified in four major domains: coping/satisfaction, behavioral, structural, and HCT/healthcare focused. Future research in larger samples would allow stratification to represent diverse patients and caregiver populations. Identifying international consensus-derived outcomes among parents/caregivers is imperative for the evaluation of HCT preparation strategies that ensure appropriate support for diverse AYA-SHCN and their families during this process and enable implementation of the most effective interventions.

Necrotizing enterocolitis: Bench to bedside approaches and advancing our understanding of disease pathogenesis.

Necrotizing enterocolitis (NEC) is a devastating, multifactorial disease mainly affecting the intestine of premature infants. Recent discoveries have significantly enhanced our understanding of risk factors, as well as, cellular and genetic mechanisms of this complex disease. Despite these advancements, no essential, single risk factor, nor the mechanism by which each risk factor affects NEC has been elucidated. Nonetheless, recent research indicates that maternal factors, antibiotic exposure, feeding, hypoxia, and altered gut microbiota pose a threat to the underdeveloped immunity of preterm infants. Here we review predisposing factors, status of unwarranted immune responses, and microbial pathogenesis in NEC based on currently available scientific evidence. We additionally discuss novel techniques and models used to study NEC and how this research translates from the bench to the bedside into potential treatment strategies.
