Extraintestinal Manifestations and Family History of Inflammatory Bowel Disease Increase the Risk of Pouchitis in a State-Level Epidemiology Study.

Introduction: Our understanding of the epidemiology of inflammatory conditions of the pouch and effectiveness of treatment is largely based on selected populations. We created a state-level registry to evaluate the incidence of pouchitis and the effectiveness of treatments used in an initial episode of pouchitis.

Methods: In a state-level retrospective cohort of all patients undergoing proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis between January 1, 2018, and December 31, 2020, we evaluated the incidence of pouchitis and compared the proportion of patients developing recurrent pouchitis and chronic antibiotic-dependent pouchitis according to initial antibiotic therapy.

Extensive Colitis and Smoking Are Associated With Postoperative Complications Within 30 Days of Ileal Pouch-Anal Anastomosis.

Background: Our understanding of outcomes after proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) is largely based on analyses of selected populations. We created a state-level registry to evaluate the epidemiology of IPAA surgery and pouch-related outcomes across the major healthcare systems performing these surgeries in our state.

Methods: We created a retrospective cohort of all patients undergoing restorative proctocolectomy with IPAA for UC at 1 of 4 centers between January 1, 2018, and December 31, 2020.

Fecal microbiota transplant for treatment of Clostridium difficile infection in immunocompromised patients.

Objectives: Patients who are immunocompromised (IC) are at increased risk of Clostridium difficile infection (CDI), which has increased to epidemic proportions over the past decade. Fecal microbiota transplantation (FMT) appears effective for the treatment of CDI, although there is concern that IC patients may be at increased risk of having adverse events (AEs) related to FMT. This study describes the multicenter experience of FMT in IC patients.

Efficacy and safety of natalizumab in Crohn's disease patients treated at 6 Boston academic hospitals.

Background: Despite trials demonstrating its efficacy, many physicians harbor concerns regarding the use of natalizumab in the treatment of patients with refractory Crohn's disease (CD). The purpose of this study was to perform a descriptive analysis of a series of CD patients not currently enrolled in a clinical trial.

Methods: A retrospective case review of patients treated with natalizumab at 6 sites in Massachusetts: Boston Medical Center, Beth Israel Deaconess Medical Center, Brigham & Women's Hospital, Lahey Clinic, Massachusetts General Hospital, and UMass Medical Center.

The evaluation of premenopausal women with anemia: what is the yield of gastrointestinal endoscopy?

Anemia is not uncommon in premenopausal women. The purpose of this study was to determine the yield of endoscopy in premenopausal women with anemia. We identified and reviewed the medical records of 168 premenopausal women who underwent upper endoscopy and/or colonoscopy for the indication of iron deficiency anemia (IDA) during the years 1996 through 2005.

Microscopic colitis. Identical clinical presentations of subtypes create diagnostic challenges.

The diagnosis of microscopic colitis should be considered in patients presenting with chronic watery diarrhea, especially middle-aged and elderly women. Diagnosis is established by colonoscopic biopsies showing histologic changes in the setting of endoscopically normal mucosa. Although the etiology of microscopic colitis remains unknown, a wide variety of effective medical treatments is available.
