Nonselective Beta-Blockers Do Not Affect Survival in Cirrhotic Patients with Ascites

Abstract

Background

The role of nonselective beta-blockers in cirrhotic patients with ascites has been recently questioned; however, definitive evidence in this regard is still lacking.

Aims

To analyze published data on the influence of nonselective beta-blockers as compared to control group on survival of cirrhotic patients with ascites.

Methods

Computerized bibliographic search on the main databases was performed. Hazard ratios from Kaplan–Meier curves were extracted in order to perform an unbiased comparison of survival estimates. Secondary outcomes were mortality in patients with refractory ascites, pooled rate of nonselective beta-blockers interruption, spontaneous bacterial peritonitis and hepato-renal syndrome incidence.

Results

Three randomized controlled trials and 13 observational studies with 8279 patients were included. Overall survival was comparable between the two groups (hazard ratio = 0.86, 0.71–1.03, p = 0.11). Study design resulted as the main source of heterogeneity in sensitivity analysis and meta-regression. Mortality in refractory ascites patients was similar in the two groups (odds ratio = 0.90, 0.45–1.79; p = 0.76). No difference in spontaneous bacterial peritonitis (odds ratio = 0.78, 0.47–1.29, p = 0.33) and hepato-renal syndrome incidence (odds ratio = 1.22, 0.48–3.09; p = 0.67) was observed. Pooled rate of nonselective beta-blockers interruption was 18.6% (5.2–32.1%).

Conclusions

Based on our findings, nonselective beta-blockers should not be routinely withheld in patients with cirrhosis and ascites, even if refractory.
