Use of nonselective beta-blockers to reduce portal pressure in cirrhosis improved outcomes in adults with or without ascites, based on data from a meta-analysis of more than 1,000 patients.

Previous research has suggested that nonselective beta-blockers (NSBBs) might have a negative effect on patients with refractory ascites, but the effect on patients with and without ascites has not been assessed, wrote Laura Turco, MD, of the University of Modena and Reggio Emilia, Emilia-Romagna, Italy, and colleagues.
In a study published in Clinical Gastroenterology and Hepatology, the researchers analyzed 1,113 cirrhosis patients including 452 with ascites. Overall, 968 patients had received treatment with NSBBs. Response to pressure reduction was defined as a decrease of more than 20% from baseline or a decrease to less than 12 mm Hg.
A total of 329 of the 661 patients without ascites (50%) met the definition as responders. These responders had significantly lower odds than did nonresponders of a combination of clinical events including ascites, variceal hemorrhage, or encephalopathy (odds ratio, 0.35) and also had significantly lower odds than nonresponders of liver transplantation or death (OR, 0.50).
A total of 188 of the 452 patients with ascites were responders (42%). These responders had significantly lower odds than those of nonresponders (OR, 0.27) of variceal hemorrhage, refractory ascites, spontaneous bacterial peritonitis, or hepatorenal syndrome. The responders also had significantly lower odds of liver transplantation or death (OR, 0.47).
The results are important in light of concerns about the impact of NSBBs on renal function and mortality in cirrhosis patients with ascites, the researchers said.
The study findings were limited by several factors, including the use of retrospective data from prospective studies, and the incomplete collection of data on the variables of comorbidities, hepatocellular carcinoma, and other predictive scores; alcohol use or abstinence was a potential confounder as well, the researchers noted.
However, “By showing that reductions in portal pressure induced by NSBB-based pharmacologic therapy improve outcomes and decrease mortality, our study supports the use of NSBB in all clinical settings (primary or secondary prophylaxis) and in both patients with or without ascites,” they concluded. They found no heterogeneity among the studies included in the analysis.
The study was supported by multiple sources including the University of Modena and Reggio Emilia, Yale Liver Center, National Institutes of Health, and Instituto de Salud Carlos III, and was cofunded by the European Union. The researchers had no financial conflicts to disclose.
