Review of pharmacotherapeutic treatments for primary sclerosing cholangitis.

Background: The objective of this review was to evaluate pharmacotherapeutic treatments for primary sclerosing cholangitis (PSC) through a literature search of current published data. A review of the current clinical data for each treatment is discussed.
Methods: We conducted a systematic literature search for articles using EMBASE (1980 to April 1, 2018), and MEDLINE (1948 to April 1, 2018) using Ovid, to identify studies investigating various therapies in PSC. Search terms included the following: primary sclerosing cholangitis, cholangitis, sclerosing cholangitis; ursodeoxycholic acid, glucocorticoids, cyclosporine, tacrolimus, methotrexate, azathioprine, 6-mercaptopurine, penicillamine, anti-TNF, antibiotics, and probiotics. We also performed a review of current clinical trials using ClinicalTrials.gov. We considered for review relevant studies published in English, pilot studies, and randomized controlled trials involving human subjects.
Results: Therapies that have been investigated in the management of PSC include those used in search terms and others that were not included in our search parameters. Analysis of published data involving each therapy was explored and none have shown any sustained, significant benefit in the treatment of PSC. In terms of relevance to patient care and clinical practice, this review evaluates and compares various pharmacotherapeutic treatments for PSC where liver transplantation remains the only definitive treatment. Conclusions: To date, no clinical study of any drug has demonstrated effectiveness in terms of survival benefit or a decreased need for liver transplantation. More clinical studies are needed, and patients need to be adequately informed before any medical therapy for PSC is undertaken.
