Abstract:
Objective To evaluate the clinical and histological outcomes in a cohort of chronic hepatitis B (CHB) patients who had histologically confirmed severe liver fibrosis and received lamivudine (LAM) therapy for up to 10 years. Methods Thirty-nine CHB patients with severe liver fibrosis (Ishak fibrosis score≥4) were treated with LAM for up to 10 years. Disease progression liver histological improvement, virological and biochemical responses were evaluated during follow-up. Data were analyzed using paired t test, Fisher exact test and Willcoxon test. Results Twenty-eight patients completed the 10-year follow-up. There were 5 (17.9% ) patients with disease progression.At the end of follow up, 16 patients received a second liver biopsy, which showed significant improvement of histological activity index (1.1 ± 1.4 vs 7. 1 ± 3.2, t =- 0.82, P＜0.01 ) and Ishak fibrosis score (3.6±2.2 vs 5.3±0.7, t= -2.89, P＜0.05) compared to baseline. There were 3 cases with Ishak fibrosis score improved from F5 to F0. Among 27 patients, 3(11% ) cases achieved hepatitis B surface antigen (HBsAg) loss and 2 (7 % ) achieved HBsAg seroconversion. At the end of follow-up, 19 out of 23 (83% ) hepatitis B e antigen (HBeAg) positive patients obtained HBeAg loss and 9 (39 % ) obtained HBeAg seroconversion. During LAM treatment, 11 patients experienced virological breakthrough or detected documented LAM-related resistance mutation. The viral loads of all patients were below 1 ×103 copy/mL at the end of follow-up after rescued by add-on or switch to another nucleotide analog.Conclusions Long-term LAM therapy can delay the disease progression in CHB patients with severe liver fibrosis, increase HBsAg and HBeAg loss rates, sustain suppression of HBV replication at a low level and even totally reverse the liver fibrosis in some patients. The effect of LAM resistance mutation on disease outcomes would be reduced by rescue therapy.
