Background/Aims: The renal effects of nucleos(t)ide analogs in patients with chronic hepatitis B are controversial. We aimed to compare the impact of entecavir (ETV) and tenofovir (TDF) on renal function in patients with hepatitis B virus (HBV)-related cirrhosis.
Methods: We performed a retrospective cohort study of 235 consecutive treatment-naive patients with HBV-related cirrhosis who were treated with ETV or TDF between December 2012 and November 2013 at Severance Hospital, Seoul, Korea.
Results: Compensated cirrhosis was noted in 183 patients (ETV 130, TDF 53), and decompensated cirrhosis was noted in 52 patients (ETV 32, TDF 20). There were no significant changes in estimated glomerular filtration rates (eGFR) from baseline in either the ETV- or TDF-treated groups at week 96 (Chronic Kidney Disease Epidemiology Collaboration, ETV ?1.68% and TDF ?5.03%, p=0.358). Using a multivariate analysis, the significant factors associated with a decrease in eGFR >20% were baseline eGFR, diabetes mellitus (DM), and the use of diuretics. The use of antiviral agents and baseline decompensation were not determined to be significant factors.
Conclusions: In patients with HBV-related cirrhosis, TDF has shown similar renal safety to that of ETV over a 2-year period. Renal function should be closely monitored, especially in patients who exhibit decreasing eGFR, DM, and the use of diuretics.
