Chen S, Wang JJ, Wang QQ, Hu JW, Dong S, Hu LJ, Jian YC, Liu XY, Yang GM, Xiong WJ - Patient Prefer Adherence (2015)

Bottom Line: Significant heterogeneity (P<0.1, I (2)=92%) existed between the two treatment groups in %MAP reduction.No considerable difference could be observed in the %MAP reduction through the poor overlapping CI boundaries.Carvedilol has a greater portal hypertensive effect than propranolol.

ABSTRACT

Purpose: Several randomized controlled clinical trials have been conducted to investigate the role of carvedilol and propranolol on the effect of portal pressure in patients with cirrhosis, leading to controversial results. Current meta-analysis was performed to compare the efficacy of the two drugs on portal pressure.

Patients and methods: Two-hundred and ninety eligible patients were recruited. Published studies were selected based on PubMed, the Cochrane Library, Chinese Journal Full-text Database, and Wanfang Database. The outcome measurements included the mean difference (MD) in the percentage of hepatic vein pressure gradient reduction (%HVPG reduction), the risk ratio (RR) of nonresponders in hemodynamic assessment, and the percentage of mean arterial pressure reduction (%MAP reduction). Subgroup analysis was performed.

Results: Seven trials were identified (including five acute and three long-term drug administration randomized controlled trials). A summary of pooled MD between the %HVPG reduction is as follows: overall -8.62 (confidence interval [CI] -11.76, -5.48, P<0.00001), acute -10.05 (CI -14.24, -5.86, P<0.00001), and long term -6.80 (CI -11.53, -2.07, P=0.005), while summary of pooled RR of hemodynamic nonresponders with carvedilol was as follows: overall 0.64 (CI 0.51, 0.81, P=0.0002), acute 0.63 (CI 0.47, 0.85, P=0.002), and long term 0.67 (CI 0.47, 0.97, P=0.03). Both of the outcome measurements favored carvedilol. Significant heterogeneity (P<0.1, I (2)=92%) existed between the two treatment groups in %MAP reduction. No considerable difference could be observed in the %MAP reduction through the poor overlapping CI boundaries.

Conclusion: Carvedilol has a greater portal hypertensive effect than propranolol. Further comparative trials of the two drugs are required to identify the effect of MAP reduction.

Mentions: Overall, 44 pertinent studies were identified. Thirty-one were excluded by reading the abstract because they did not include randomized clinical trials. The remaining eleven were RCTs and were assessed for inclusion in the present meta-analysis (Figure 1).
