The objective of this study was to elucidate and compare morphological and metabolic alterations in HIV-infected antiretroviral-naive patients receiving two nucleosides plus the PI nelfinavir (NFV) or the nonnucleoside reverse transcriptase inhibitor nevirapine (NVP). Forty-three patients (NFV, n = 20; NVP, n = 23) receiving 612 months of treatment were analyzed. Morphological changes were evaluated by bioelectrical impedance analysis, standard anthropometrics, and clinical examination. Serum total cholesterol (TC), low-density and high- density (HDL-c) lipoprotein cholesterol, triglycerides, glucose, and insulin were determined, among other metabolic parameters. No baseline differences were observed between groups. TC increased in both arms (NVP, 11%; NFV, 17%). HDL-c also increased in both groups, although more markedly in those receiving NVP (44% vs. 20%); on-treatment levels were also elevated (1.57 vs. 1.28 mmol/liter). As a consequence of these changes, the TC/HDL-c ratio dropped by 22% in the NVP arm and remained stable in the NFV group. With the use of NFV, the TC/HDL-c ratio and attendant cardiovascular risk did not change. In contrast, NVP offered benefits regarding lipid status, as manifested by enhanced HDL-c concentrations and decreased TC/HDL-c ratios. Inclusion of NVP should be considered when deciding upon antiretroviral regimens for patients at high coronary risk.
