ABSTRACT
BACKGROUND AND AIMS:
Tenofovir (TDF)-associated renal dysfunction has been described in various studies of human immunodeficiency virus-infected patients. Our goal is to examine the incidence and magnitude of decrease in renal function in chronic hepatitis B patients treated with TDF.METHODS:
We performed a case-cohort study of 103 patients on TDF 300 mg and 103 patients unexposed to TDF (Entecavir) at 4 centers, who were matched for age±10 years, sex, and baseline estimated glomerular filtration rate (eGFR) group. Calculation and evaluation of eGFR were performed with both the Cockcroft-Gault formula and the Modification of Diet in Renal Disease formula.RESULTS:
The exposed and unexposed populations were well matched with a similar mean age (44±10 y), proportion of male patients (63.1%), and baseline eGFR groups (86.4% unimpaired). There was no significant difference in the proportion of patients reclassified to a more severe renal classification (RMSRC) or in the proportion of patients with decrease in eGFR of ≥20% in those exposed to TDF versus control. The incidence density for RMSRC was 7.4 cases per 100 patient-years in the exposed group compared with 11.5 cases per 100 patient-years in the unexposed group (95% CI, 0.31-1.34). The relative risk of exposed to unexposed was 0.64 (95% CI, 0.31-1.34). On Cox proportional hazard analysis following adjustment for sex, age, baseline diagnosis hypertension, diabetes, impaired baseline renal function, and cirrhosis, TDF was not a predictor for RMSRC or decrease in eGFR≥20%.CONCLUSIONS:
TDF treatment was not an independent predictor for significant deterioration of renal function. Renal function of chronic hepatitis B patients on antiviral therapy should be monitored, especially in those who are older and/or with mildly impaired renal function.
