Is the risk of tenofovir-induced nephrotoxicity similar in treatment-naïve compared to treatment-experienced patients?

Abstract

Background: Tenofovir disoproxil fumarate (TDF) is the recommended first-line nucleoside reverse transcriptase inhibitor (NRTI) in the management of human immunodeficiency virus (HIV); however, its use is associated with nephrotoxicity. Aim: To assess if the risks of renal impairment were similar in treatment-naïve compared to treatment-experienced patients initiating tenofovir given their different background clinical characteristics. Method: This was a retrospective observational study conducted at the University Malaya Medical Centre, Malaysia and included all HIV-infected adults who received tenofovir for at least 3 months and had an estimated glomerular filtration rate (eGFR) >60 mL/min..
