Monitoring of Renal Function among HIV-Infected Patients Receiving Tenofovir in a Resource-Limited Setting.

The use of tenofovir disoproxil fumarate (TDF) is supposed to be increased in a resource-limited setting due to the changing of the guidelines. TDF-associated renal function declines among HIV-infected patients were defined by an increase of serum creatinine (SCr) >1.5 times, a 25% decrease in calculated creatinine clearance (CCrCl), or an estimated glomerular filtration rate (eGFR) from the baseline. Of all, 99% were antiretroviral treatment (ART)-experienced patients. At the 30th month, 19 (5.3%), 53 (14.9%), and 63 (17.7%) patients had renal function decline as defined by the above criteria with an incidence of 4.5, 12.5, and 14.6/100 person-year. A proportion of patients with a renal function decline detected by CCrCl or eGFR criteria was not different (P = .301), whereas, it differed from that detected by SCr criteria (P < .001). In conclusion, we encourage either CCrCl or eGFR calculations in monitoring renal function decline among HIV-infected patients receiving TDF in resource-limited settings.
