In such conditions, the influence of hepatitis B virus (HBV) infection and antiviral agents on renal function becomes a consideration with long-term use and ageing. Membranous glomerulonephritis has been confirmed as the most common histological renal lesion. In this study, we reported a CHB patient with decompensated cirrhosis showing a significant improvement in massive proteinuria along with elevation of estimated glomerular filtration rate (eGFR) after 1 year treatment with telbivudine. However, a well-designed study should be performed to confirm the causal association, and the molecular mechanism needs further investigation.
