- Abstract
Objective Evaluate the effectiveness and safety of simplification of tenofovir/emtricitabine/efavirenz (TDF/FTC/EFV) in selected treatment-experienced HIV-1-infected patients who have been virologically suppressed for>3 months on their current regimen. Methods We selected patients who started the simplified regimen between December 1st 2008 and March 31st 2012. Exclusion criteria: prior therapeutic failure, presence of resistance mutations to any component of TDF/FTC/EFV and patients previously observed in other centers. Efficacy and safety assessments were performed at baseline, 4 weeks after switch and then every 12-24 weeks. Statistical analysis was performed with SPSS version 20.0. Results 384 patients were evaluated; 302 (79%) male; mean age 47 (SD=10) years; median CD4 cells count was 504 cells/mm3 (367-710). Baseline median glomerular filtration rate (eGFR; Cockcroft-Gault equation) was 100 mL/min (86-116) and median ALT was 33 U/L (21-47). Median total cholesterol (TC) was 205 mg/dL (176-236), high-density lipoproteins (HDL) 45 mg/dL (38-54); low-density lipoproteins (LDL) 130 mg/dL (108-151); triglycerides (TG) 125 mg/dL (84-176). Prior NNRTI-based regimen in 327 (85%) patients (TDF/FTC and EFV in 76%); protease inhibitor in 52 (14%) and integrase inhibitor in 5 (1%). Discontinuation of treatment occurred in 49 patients (13%) after a mean time of 1.1 years (SD=1.1) of follow-up: nervous system symptoms (n=11), decreased eGFR (n=5), virological failure (n=5), pregnancy (n=5), gastrointestinal symptoms (n=3), rash (n=1), other reasons (n=2); 12 patients dropped out the treatment and 5 died. Occurrence of blips (transient increase in VL ≤200 copies/mL) was documented in 98 (26%) patients; in 70, VL decreased to <20 copies/mL after the blips and in 28 VL is not yet available. 317 patients (83%) achieved≥48 weeks of follow-up after simplification. Compared with baseline, significantly higher levels of CD4 cells count, HDL and eGFR were found and lower levels of TC, LDL and TG.
