Abstract
BACKGROUND
Previous studies have demonstrated that ursodeoxycholic acid (UDCA) possesses anti-inflammatory, antioxidant, and anti-fibrotic properties, and it may reduce the degree of liver damage caused by nonalcoholic steatohepatitis (NASH). However, the effectiveness of UDCA in improving liver function and histology in cases of NASH remains unclear. Therefore, we performed a meta-analysis to assess the efficacy of UDCA in the treatment of NASH.
METHODS
PubMed, Web of Science, Embase, Cochrane, and other databases were searched for randomized controlled trials (RCTs) published before 1 January 2022, in which UDCA was used to treat patients with NASH.
RESULTS
A total of 8 studies with 655 participantsmet the criteria for inclusion in this meta-analysis. The forest plot displayed that UDCA treatment significantly reduced blood concentrations of alanine aminotransferase (ALT) and γ-glutamyl transferase (GGT). However, the pooled effect size results did not suggest any significant effect of UDCA on anthropometric characteristics or hepatic histology.
CONCLUSION
UDCA therapy can effectively reduce serum levels of ALT and GGT in patients with NASH but has no significant effects on physical characteristics or liver histology. Further large-scale and dose-response clinical studies are needed to evaluate the clinical potential of UDCA in treating NASH.
