Effects of nucleoside analogue on patients with chronic hepatitis B-associated liver failure: meta-analysis.

PURPOSE: The effectiveness of nucleoside analogue on patients with chronic hepatitis B-associated liver failure is still controversial. To address this issue, we did a review of the literatures and analyzed the data with emphasis on the survival and reduction in serum HBV DNA level.

METHODS

We searched 11 randomized controlled trials that included 654 patients with chronic hepatitis B-associated liver failure. 340 patients adopted nucleoside analogue, such as lamivudine (LAM), entecavir (ETV), telbivudine (LdT), or tenofovir disoproxil fumarate (TDF), and the remaining 314 patients adopted no nucleoside analogue or placebo. A meta-analysis was carried out to examine the survival, HBV e antigen serologic conversion, and reduction in serum HBV DNA level. The pooled odds ratio (OR) was used to reflect the treatment effects.

RESULTS

The overall analysis revealed nucleoside analogue significantly improved 1-month (OR = 2.10; 95% CI, [1.29, 3.41]; p = 0.003), 3-month (OR = 2.15; 95% CI, [1.26, 3.65]; p = 0.005), 12-month survival (OR = 4.62; 95% CI, [1.96, 10.89]; p = 0.0005). Comparison of 3-month HBV DNA showed significant reduction for adoptive nucleoside analogue patients (OR = 54.47; 95% CI, [16.37, 201.74]; p<0.00001). Comparison of 3-month HBV e antigen serologic conversion showed a highly significant improvement of HBV e antigen lost for patients received adoptive antiviral therapy (OR = 6.57; 95% CI, [1.64, 26.31]; p = 0.008).

CONCLUSIONS

The benefits of nucleoside analogue on patients with chronic hepatitis B-associated liver failure is significant for improving patient survival, HBV e antigen serologic conversion, and rapid reduction of HBV DNA levels.
