RESUMO
Objectives: To analyse lipid changes and tolerability in a cohort of HIV-infected patients who switched their antiretroviral regimens to rilpivirine/emtricitabine/tenofovir (RPV/FTC/TDF) in a real-world setting. Methods: PRO-STR is a 48 week prospective observational post-authorization study in 25 hospitals. Patients with a viral load <1000 copies/mL, receiving at least 12 months of combination ART (cART), with constant posology for at least the prior 3 months, were categorized according to previous treatment [NNRTI or ritonavir-boosted PI (PI/r)]. Analytical tests were performed at the baseline visit, between week 16 and week 32, and at week 48. Results: A total of 303 patients were included (mean age 46.6 years; male 74.0%; previous treatment 74.7% NNRTI and 25.3% PI/r). Both groups exhibited significantly reduced lipid profiles, except for HDL cholesterol, for which a non-significant increase was observed. [NNRTI patients: total cholesterol (baseline: 195.5â±â38.4 mg/dL; week 48: 171.0â±â35.5 mg/dL), total cholesterol/HDL ratio (baseline: 4.2â±â1.2; week 48: 4.0â±â1.2), HDL (baseline: 49.1â±â12.0 mg/dL; week 48: 49.2â±â45.8 mg/dL), LDL (baseline: 119.2â±â30.2 mg/dL; week 48: 114.2â±â110.7 mg/dL), and triglycerides (baseline: 136.6â±â86.8 mg/dL; week 48: 113.4â±â67.8 mg/dL); PI/r patients: total cholesterol (baseline: 203.2â±â48.8 mg/dL; week 48: 173.4â±â36.9 mg/dL), total cholesterol/HDL ratio (baseline: 4.7â±â1.6; week 48: 4.0â±â1.2), HDL (baseline: 46.4â±â12.5 mg/dL; week 48: 52.1â±â54.4 mg/dL), LDL (baseline: 127.0â±â36.3 mg/dL; week 48: 111.4â±â35.8 mg/dL), and triglycerides (baseline: 167.6â±â107.7 mg/dL; week 48: 122.7â±â72.1 mg/dL)]. The most common intolerances were neuropsychiatric in the NNRTI patients and gastrointestinal and metabolic in the PI/r patients, and these intolerances were significantly reduced in both groups at week 48 [NNRTI: neuropsychiatric (baseline: 81.3%; week 48: 0.0%); PI/r: gastrointestinal (baseline: 48.7%; week 48: 0.0%) and metabolic (baseline: 42.1%; week 48: 0.0%)]. Conclusions: RPV/FTC/TDF improved the lipid profiles and reduced the intolerances after switching from NNRTI or PI-based regimens, in a cohort of HIV-infected patients.
