Summary of results:
⋅At baseline, TDF initiators were older, and more likely to be male, on ART and virologicallysuppressed, to have higher eGFR, higher CD4+ cell count, current or recent ritonavir-boosted protease inhibitor and atazanaviruse, and hypertension. (Table 1)
⋅1-year eGFR trajectory: In patients with reduced kidney function (eGFR<90 mL/min) at baseline, TDF was associated with faster eGFR decline from 0 to 6 month, followed by a recovery of kidney function between 6 to 12 month post-ART. For those with baseline eGFR≥90 mL/min, 1-year eGFR change was not significantly different by treatment groups. (Figures 1-3)
⋅1-year eGFR change vs. long-term ESRD risk:There were 68 incident ESRD that occurred among those who stayed on TDF or NRTI-containing therapy for ≥1 year. In this group, rapid eGFRdecline (>25% loss in eGFR and to a level of <60 mL/min) during the first year of ART was associated with higher risk of ESRD in patients with baseline eGFR<90 mL/min. This risk was similar by therapy types. (Table 2)
