Abstract
Background: Microscopic colitis (MC) is a chronic inflammatory bowel disorder causing watery diarrhea despite normal endoscopic findings. Budesonide is the only approved therapy, yet long-term durability and the need for alternatives in steroid-dependent or -refractory cases remain unclear.
Methods: We performed a retrospective single-center cohort study of all patients with histologically confirmed MC between 2013 and 2022, with ≥3 months of follow-up. Demographics, clinical features, treatments, and outcomes were collected. Clinical remission followed Hjortswang criteria: fewer than three stools per day or fewer than one watery stool per day on average.
Results: A total of 239 idiopathic MC patients met inclusion criteria. Spontaneous remission occurred in 19.2%, more often in males (OR 2.39, p=0.02). Corticosteroids, predominantly budesonide, were prescribed in 78.7% and induced remission in 75.5% within three months. Relapse affected 54.8% of responders, typically during tapering (44.6%) or shortly after cessation (55.3%). Younger age predicted relapse (OR 0.97, p=0.003). Conventional alternatives, including 5-ASA, cholestyramine, methotrexate, and azathioprine, were largely ineffective after corticosteroid failure or dependency. Advanced therapies (anti-TNF agents, vedolizumab, JAK inhibitors) were initiated in 12.6%, more often in younger patients (OR 0.95, p=0.001) and those with a family history of IBD (OR 4.11, p=0.03). These therapies achieved post-induction remission in 70% of refractory cases. Two patients required colectomy.
Conclusion: In this large cohort with long-term follow-up, budesonide remained the primary treatment, yet over half of responders relapsed during tapering or after discontinuation. Conventional alternatives showed limited benefit. Advanced therapies demonstrated meaningful effectiveness in steroid-refractory or steroid-dependent MC, underscoring the need for broader therapeutic options.
期刊介绍:
The Journal Acta Gastro-Enterologica Belgica principally publishes peer-reviewed original manuscripts, reviews, letters to editors, book reviews and guidelines in the field of clinical Gastroenterology and Hepatology, including digestive oncology, digestive pathology, as well as nutrition. Pure animal or in vitro work will not be considered for publication in the Journal. Translational research papers (including sections of animal or in vitro work) are considered by the Journal if they have a clear relationship to or relevance for clinical hepato-gastroenterology (screening, disease mechanisms and/or new therapies). Case reports and clinical images will be accepted if they represent an important contribution to the description, the pathogenesis or the treatment of a specific gastroenterology or liver problem. The language of the Journal is English. Papers from any country will be considered for publication. Manuscripts submitted to the Journal should not have been published previously (in English or any other language), nor should they be under consideration for publication elsewhere. Unsolicited papers are peer-reviewed before it is decided whether they should be accepted, rejected, or returned for revision. Manuscripts that do not meet the presentation criteria (as indicated below) will be returned to the authors. Papers that go too far beyond the scope of the journal will be also returned to the authors by the editorial board generally within 2 weeks. The Journal reserves the right to edit the language of papers accepted for publication for clarity and correctness, and to make formal changes to ensure compliance with AGEB’s style. Authors have the opportunity to review such changes in the proofs.
