Cardiovascular Manifestations in.inflammatory Bowel Disease: A Systematic Review of the Pathogenesis and Management of Pericarditis

Inflammatory bowel disease (IBD) is a chronic condition of the bowel that can be further categorized into ulcerative colitis and Crohn's disease. Rarely, this condition can be associated with pericarditis, which can be an extraintestinal manifestation of the disease or drug-induced. This review aims to determine the pathogenesis and management of pericarditis in IBD. In this review, the goal is to elucidate the pathogenesis of pericarditis in IBD and determine if pericarditis is an extraintestinal manifestation of IBD or a complication of current drug therapy used to manage IBD. Additionally, this review intends to explain the first-line management of pericarditis in IBD and explore the role of biologicals in attenuating pericarditis. An electronic search was conducted to identify relevant reports of pericarditis in IBD, and a quality assessment was conducted to identify high-quality articles according to the inclusion criteria. Full-text articles from inception to November 2020 were included, while non-English articles, gray literature, and animal studies were excluded. The majority of studies suggest that pericarditis arises as a complication of drug therapy by 5-aminosalicylic acid derivatives such as sulfasalazine, mesalamine, and balsalazide, and it occurs due to IgE-mediated allergic reactions, direct cardiac toxicity, cell-mediated hypersensitivity reactions, and humoral antibody response to therapy. Drug cessation or the initiation of a corticosteroid regimen seems to be the most effective means of managing pericarditis in IBD due to drug therapy or an extraintestinal manifestation.
