Role of Ursodeoxycholic Acid in Treating and Preventing Idiosyncratic Drug-Induced Liver Injury. A Systematic Review

Blog Article

Introduction: Treatment is generally not available for drug-induced liver injury (DILI) patients except in some specific circumstances.The management bolia outlet gent of DILI is based on the withdrawal of the responsible drug and monitoring the patients and only a few patients need to be referred to a transplant center.Some studies on the role of ursodeoxycholic acid (UDCA) in DILI have been published.The aim of this study was to perform a systematic review of the role of UDCA in the treatment and prevention of DILI.

Methods: A search was undertaken in PubMed, with the key words ursodeoxycholic acid, drug-induced liver injury and hepatotoxicity following the PRISMA guidelines.Results: A total of 33 publications were identified: 25 case reports and 8 case series.In 18 of the 25 cases reports (22 patients), authors reported improvement of liver injury associated with UDCA therapy whereas 7 case reports did not show clinical or biochemical improvement after UDCA treatment.There were 4 studies evaluating the role of UDCA in the treatment of DILI, three royal nomadic 5413 rug prospective (one being a clinical trial) and one retrospective studies.

Three studies observed liver profile improvements associated with UDCA.In addition, four studies evaluated UDCA in the prevention of DILI: one pilot study, two randomized clinical trials (RCT) and one retrospective study.Three of these studies observed a lower percentage of patients with an increase in transaminases in the groups that used UDCA for DILI prevention.Conclusion: According to available data UDCA seems to have some benefits in the treatment and prevention of DILI.

However, the design of the published studies does not allow a firm conclusion to be drawn on the efficacy of UDCA in DILI.A well designed RCT to evaluate the role of UDCA in DILI is needed.
