Positioning Therapies in Ulcerative Colitis

Abstract

Ulcerative colitis (UC) is a chronic, idiopathic inflammatory bowel disease (IBD) that affects the large intestine. Several therapeutic drug classes are available for the treatment of UC: salicylates, corticosteroids, thiopurines, calcineurin inhibitors, anti-tumor necrosis factor (TNF) agents, anti-adhesion molecules, and, more recently, small molecules directed against the Janus kinase (JAK) pathways, and ustekinumab (anti IL12/23). Other drugs are currently in development, and they will be probably available for UC patients in the near future. Several therapeutic algorithms have been proposed for the treatment of UC patients, yet these are predominantly based on expert opinions rather than high-quality evidence, mainly due to the lack of head-to-head trials, especially for monoclonal antibody and small molecule therapies. The optimal position of therapies in these algorithms remains unclear. Therefore, we conducted this review of the literature to provide an up-to-date overview of the available evidence on this topic.
