  • Objective: hepatitis B virus-associated membranous nephropathy (HBV-MN) is the most common pathological type of hepatitis B virus-associated glomerulonephritis. This study evaluated the efficacy of entecavir antiviral therapy for HBV-MN patients due to the intolerable side effects of interferon-alpha and high incidence rate of drug-resistance in lamivudine therapy. Method: thirty-two patients with HBV-MN were identified by biopsy and treated with entecavir for 52 weeks. These patients were followed up to evaluate outcomes of entecavir-treatment. Descriptive statistics were used to summarize patient demographics and treatment outcomes. Results: entecavir treatment reduced 24-h urinary protein excretion. The total probability of partial proteinuria and complete remission at 24 and 52 weeks was 53.1 and 78.1 %, respectively. A decrease of circulating HBV-DNA was observed in all patients with active HBV replication. The significant decrease of 24-h urinary protein began at 12 weeks, as early as the decrease of serum HBV-DNA level. The serum HBV DNA titers at baseline and after 52 weeks of treatment were 4.3 ± 2.8 log10 and 2.3 ± 1.7 log10, respectively. Meanwhile, eGFR increased from 100.3 ± 20.5 ml/min/1.73 m2 at baseline to 107.7 ± 15.9 ml/min/1.73 m2 after 52 weeks of treatment. The serum alanine aminotransferase level (ALT) gradually decreased to normal during entecavir antiviral treatment. Conclusions: entecavir treatment in HBV-MN patients was carefully described. Complete remission and HBV replication suppression were induced by entecavir treatment in HBV-MN patients. Patients with high serum creatinine (Scr), ALT and low eGFR levels benefit more from entecavir treatment. Entecavir therapy is well tolerated by patients and no adverse reactions were observed.
