Abstract

Whether the combination of lamivudine (LAM) plus adefovir (ADV) de novo is more effective than entecavir (ETV) monotherapy in patients with HBV-associated decompensated cirrhosis is still controversial. We searched seven randomized controlled trials that included 411 patients in this meta-analysis. There are 205 and 206 patients in these two groups separately. The pooled risk ratio (RR) and mean difference (MD) were used to assess the treatment effects. ETV monotherapy significantly improved Child–Turcotte–Pugh (CTP) scores (MD = 0.33, 95%CI [0.21–0.44], P < .00001), and was associated with lower rates of serum creatinine increase compared LAM + ADV combination therapy (RR = 4.76, 95%CI [1.11–20.33], P = .04) at 48 weeks. The reduction of alanine aminotransferase (ALT) levels, HBV DNA levels, the rate of ALT normalization, undetectable HBV DNA, HBV e antigen (HBeAg) loss, HBeAg seroconversion and mortality were similar between the two groups. ETV is more effective than LAM + ADV in improving CTP scores at 48 weeks. Both of the LAM + ADV and ETV had similar efficacy in improving virological and biochemical parameters at 48 weeks of follow-up. Furthermore, use of these agents in decompensated HBV patients was generally safe and well tolerated at 48 weeks. However, the nephrotoxicity of ADV, and the potential adverse effects of ETV should be considered and monitored during prolonged therapy.
