AimThe objective of this meta-analysis was to evaluate the effect of ursodeoxycholic acid (UDCA) therapy on serum liver function tests.MethodsPubMed, Web of Science, Scopus and Google Scholar databases were searched to identify randomized placebo-controlled trials assessing the impact of UDCA on hepatic parameters. Meta-analysis was conducted using a random-effects model and sensitivity analysis through the leave-one-out method in the Review Manager statistical software version 5.3.ResultsAfter UDCA treatment, meta-analysis revealed a significant reduction of alanine aminotransferase (weighted mean difference [WMD]: -15.28 U/L, 95% confidence interval [CI]: -23.42, -7.15, P = 0.0002, I2 = 97%), aspartate aminotransferase (WMD: -16.13 U/L, 95% CI: -23.84, -8.42, P < 0.0001, I2 = 97%), gamma-glutamyl transferase (WMD: -23.29 U/L, 95% CI: -33.97, -12.61, P < 0.0001, I2 = 97%), alkaline phosphatase (WMD: -93.80 U/L, 95% CI: -126.36, -61.25, P < 0.0001, I2 = 95%) and bilirubin (WMD: -0.18 U/L, 95% CI: -0.35, -0.01, P = 0.04, I2 = 93%), but not significant changes in albumin levels (WMD: 0.10 U/L, 95% CI: -0.05, 0.24, P = 0.18, I2 = 80%).ConclusionThe results of the present meta-analysis suggest a hepatoprotective effect of UDCA by reducing serum liver parameters.© 2020 The British Pharmacological Society.
