The objective of this study is to evaluate changes in Framingham score (from low to moderate, from moderate to high) based on changes in lipid profile and other parameters from baseline to 48 weeks of HAART in naïve patients or patients in second line of treatment, considering LPV/r vs EFV based HAART. The null hyphotesis is that there is an increased Framingham score in patients treated with LPV/r as second line treatment and in patients treated with LPV/r or EFV regimen as first line treatments.
