What do we know today about drug-induced microscopic colitis? A case of lymphocytic colitis on olmesartan.
Microscopic colitis is part of the differential diagnosis of chronic watery diarrhea. Colonoscopy discloses a normal looking mucosa, therefore its diagnosis is based on histology of colonic biopsies. Two main phenotypes are distinguished: collagenous colitis and lymphocytic colitis. A third entity, incomplete microscopic colitis or unspecified microscopic colitis has been reported in the literature. It affects preferentially women over 60 years of age and its association with certain drugs is increasingly established. In case of suspected drug-induced microscopic colitis, identification of the responsible drug is a key to management. After discontinuation of the suspected drug, the gold standard of treatment is budesonide both for induction and for maintenance in case of clinical relapse, as is often the case after discontinuation. Therapy with immunomodulators, biologics, or surgery is reserved for refractory forms of microscopic colitis after multidisciplinary consultation. Through the clinical case of colitis on olmesartan, we will review the latest recommendations on drug-induced microscopic colitis.
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.
