Recurrent myocarditis in a patient with active ulcerative colitis: a case report and review of the literature

BMJ Open Gastroenterol. 2021 Mar;8(1):e000587. doi: 10.1136/bmjgast-2020-000587.

Abstract

Inflammatory bowel diseases such as ulcerative colitis (UC) may be complicated by several extraintestinal manifestations. These involve joints, skin, eyes and less commonly lungs and heart. Myocarditis may result from the toxic effect of drugs (ie, mesalazine) commonly used for the treatment of UC or due to infections (eg, Coxsackieviruses, enteroviruses, adenovirus). Here, we report a case of a 26-year old man affected by UC and complicated by two episodes of myocarditis. Both episodes occurred during two severe exacerbations of UC. However, in both cases the aetiology of myocarditis remains uncertain being ascribable to extraintestinal manifestation, drug toxicity or both.

Keywords: IBD; drug toxicity; ulcerative colitis.
