Beneficial effects of lamivudine in hepatitis B virus-related decompensated cirrhosis

Abstract

Background/Aims: HBV-related chronic liver disease patients often present with hepatic decompensation and are not eligible for interferon therapy. Whether long-term lamivudine is effective in these patients was prospectively evaluated. Methods: Eighteen patients with HBV-related decompensated cirrhosis, all with quantitative DNA +ve and 10 HBeAg +ve, were given lamivudine 150 mg/d. Results: Each patient received at least 9 months (mean 17.9) of lamivudine. Three HBeAg+ve patients (30%) seroconverted to anti-HBe and one lost HBsAg during the follow-up. An improvement from baseline in the aspartate aminotransferase (130 vs. 72 IU/l, p<0.04); alanine aminotransferase (111 vs. 58 IU/l, p<0.01) and Child-Pugh score (8.3 vs. 6.7, p<0.013) was seen. Lamivudine had no significant side-effects. HBV DNA became undetectable in all patients by 8 weeks of therapy. In three (17%) patients, HBV DNA again became positive at 9, 9 and 27 months. YMDD mutant was, however, detected in only one (6%). A significant reduction was noted in the morbidity and hospitalizations for complications of liver disease before and after starting lamivudine (1.5±0.7 vs. 0.6±0.7, p<0.002). Conclusions: In decompensated HBV-related cirrhosis, lamivudine: i) is effective in suppressing HBV DNA and seroconversion to anti-HBe (30%), ii) can achieve significant improvement in clinical and biochemical status of liver functions.
