Navigating the pharmacotherapeutic management of comorbid inflammatory bowel disease and primary sclerosing cholangitis

Expert Opin Pharmacother. 2024 Sep;25(13):1835-1849. doi: 10.1080/14656566.2024.2407022. Epub 2024 Oct 11.

Abstract

Introduction: Primary sclerosing cholangitis (PSC) is the most specific hepatobiliary extraintestinal manifestation in inflammatory bowel disease (IBD). PSC ultimately has a poor prognosis, with disease progression resulting in liver cirrhosis and subsequent liver failure. While there is current data for the medical management of IBD, the optimal approach for concurrent PSC-IBD is unclear.

Areas covered: This review focuses on the current literature of pharmacotherapy in the PSC-IBD population including anti-tumor necrosis factor agents, vedolizumab, JAK inhibitors, IL-12/23 inhibitors, and thiopurines. Regarding PSC-IBD, it focuses on effectiveness of IBD therapies on liver biochemistry and IBD activity as well as the advent of clinically relevant liver outcomes and safety. The authors also address the need for further advances in research.

Expert opinion: The longer-term data for pharmacological management for IBD is well established. In the concomitant PSC-IBD population there is no drug to date that has effectively reduced disease related morbidity and mortality outcomes. There are limitations in the current, mostly retrospective data on IBD drugs in PSC-IBD with respect to samples sizes, heterogenous outcomes, and lack of a high-quality surrogate endpoint in PSC. However, current data for adalimumab offers encouraging results which require further exploration with larger prospective studies.

Keywords: IL-23 inhibitors; JAK-inhibitors; Primary sclerosing cholangitis; anti TNF; anti-integrins; inflammatory bowel disease; vedolizumab.
