AI Article Synopsis
- A study was conducted to evaluate the effectiveness of adalimumab, a biological therapy, in achieving endoscopic healing in patients with upper gastrointestinal Crohn's disease.
- Out of 17 patients treated for 24 weeks, 47.1% showed endoscopic healing and 29.4% had an endoscopic response, with significant improvements in Lewis scores.
- Additionally, 84.6% of patients with clinical activity reached clinical remission, and there was a notable decrease in C-reactive protein levels, indicating improved inflammation.
Article Abstract
Background: Endoscopic healing is a key treatment target in inflammatory bowel disease; few data are available on the clinical and endoscopic efficacy of biological therapy in upper gastrointestinal Crohn's disease. This study aimed to investigate small bowel mucosal healing and clinical efficacy of adalimumab therapy by video capsule endoscopy in patients with endoscopically active upper gastrointestinal Crohn's disease.
Methods: This prospective, open-label, single-arm study included Crohn's disease patients with moderate-severe endoscopic proximal small bowel involvement, defined by a Lewis score >790. Patients were treated with adalimumab monotherapy for 24 weeks. Co-primary outcomes were endoscopic healing, defined as Lewis score <350, and endoscopic response, defined as >50% decrease in Lewis score. Secondary outcomes included clinical (Harvey-Bradshaw index <4) and biomarker remission (fecal calprotectin <250 μg/g, and C-reactive protein <5 mg/L).
Results: A total of 59 Crohn's disease patients were screened; 17 patients have met eligibility criteria and were enrolled. Endoscopic healing was observed in 8 patients (47.1%) and endoscopic response in additional 5 patients (29.4%) at 24 weeks. Median Lewis score was significantly decreased compared to baseline (1912 vs. 337, P = .0005). Eleven of 13 patients (84.6%) with clinical activity achieved clinical remission (baseline: 13/17 vs. week 24: 2/17, P < .0001). Nine of 10 patients with elevated C-reactive protein achieved normal C-reactive protein after treatment and the median C-reactive protein significantly decreased from 7.4 to 1.6 mg/L, P = .032. In contrast, no change was observed in fecal calprotectin pre- and posttreatment.
Conclusions: Adalimumab induced endoscopic healing and clinical remission in patients with active small bowel Crohn's disease, with approximately half of the patients achieving endoscopic healing.

Servei d'Aparell Digestiu, Hospital Universitari Germans Trias i Pujol (Badalona, Catalonia, Spain).
Background And Aims: Inflammatory bowel disease (IBD) develops in genetically susceptible individuals exposed to certain environmental factors, of which only a few have been established. We aimed to assess whether bariatric surgery (BS) and severe obesity are associated with an increased risk of developing IBD.
Methods: Adults diagnosed with obesity or severe obesity between 2005 and 2020 were identified from the Catalan Health Surveillance System; those diagnosed with IBD prior to the diagnosis of obesity or severe obesity were excluded.

Background: Ulcerative colitis patients who undergo ileal pouch-anal anastomosis (IPAA) without mucosectomy may develop inflammation of the rectal cuff (cuffitis). Treatment of cuffitis typically includes mesalamine suppositories or corticosteroids, but refractory cuffitis may necessitate advanced therapies or procedural interventions. This review aims to summarize the existing literature regarding treatments options for cuffitis.

Background: The Montreal classification has been widely used in Crohn's disease since 2005 to categorize patients by the age of onset (A), disease location (L), behavior (B), and upper gastrointestinal tract and perianal involvement. With evolving management paradigms in Crohn's disease, we aimed to assess the performance of gastroenterologists in applying the Montreal classification.
Methods: An online survey was conducted among participants at an international educational conference on inflammatory bowel diseases.

Background: Extraintestinal Manifestations (EIMs) of Inflammatory Bowel Disease (IBD) are frequently experienced by patients and may lead to severe symptoms and fatigue. However, the reporting patterns of these outcomes in IBD randomized controlled trials (RCTs) is not clear.
Methods: We searched placebo controlled phase 3 RCTs of advanced therapies in IBD and assessed the frequency and means of reporting EIM and fatigue data in these studies.

Background: Intestinal ultrasound (IUS) is emerging as a valuable tool to assess treatment response in inflammatory bowel disease (IBD) clinical trials. This study details how IUS defines response and remission to evaluate treatment efficacy in IBD patients.
Methods: We conducted a comprehensive search of studies from 1984 to 31 March 2024, focusing on IUS use in assessing treatment efficacy in IBD.
