Effects of Prolonged Administration of Tenofovir Disoproxil Fumarate‐Containing Antiviral Regimen on Renal Function in Low‐Risk of Kidney Injury HIV Patients

This study intended to investigate the impact of long‐term tenofovir fumarate (TDF) antiviral regimen on renal function in human immunodeficiency virus (HIV)‐infected patients with low‐risk of kidney injury. The observational study involving 100 HIV‐infected patients without underlying diseases who achieved virological suppression and immunological recovery after sustained antiviral regimen of TDF+ lamivudine+ efavirenz (TLE) for 3.19 years. Renal function, including estimated glomerular filtration rate (eGFR), blood and urine β2 microglobulin, and other parameters, was assessed every 3 months over a period of 2.5 years. The eGFR showed a slight increasement from 116.0 at month 0 to 119.7 at month 30. Blood β2 microglobulin increased from 2.02 mg/L at month 0 to 2.77 mg/L at month 30. Compared to month 0, the difference in blood β2 microglobulin was statistically significant at month 6 and months 12‐30 (P
