Efficacy and safety of rifaximin for the prophylaxis of hepatic encephalopathy: A meta-analysis.

ABSTRACT:

Background and aim

The efficacy of rifaximin in the prevention of overt hepatic encephalopathy (HE) has not been established. The aim of this study was to access the efficacy and safety of rifaximin in the prophylaxis of HE.

Methods

We conducted a meta-analysis search of the Cochrane Library, PubMed, ClinicalTrials.gov, Web of Science, and EMBASE as of March 2022. We pooled data by random-effects DerSimonian-Laird models to calculate hazard ratios (relative risks, RRs) for mortality, incidence of HE, and adverse events.

Results

Fourteen randomized controlled trials were included in the study. Rifaximin helped prevent HE (RR = -0.47, 95% confidence interval [CI]: -0.68 to -0.26) in patients with cirrhosis, but did not reduce mortality (RR = 0.03, 95% CI: -0.32 to 0.39)
