Purpose
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.

Primary Outcome Measures:
- Risk for CV events [ Time Frame: Per year ]Changes in Framingham risk for CV events (from low to moderate, from moderate to high) based on changes in lipid parameters from baseline at 6, 12, Q12 months after the initiation of a LPV/r based HAART regimen in the whole population under study.Participants will be followed for an average of 24 months .
- Risk for CV events [ Time Frame: Per year ]Changes in Framingham risk for CV events (from low to moderate, from moderate to high) based on changes in lipid parameters from baseline at 6, 12, Q12 months after the initiation of a LPV/r based HAART regimen in male subpopulation.Participants will be followed for an average of 24 months .
- Risk for CV events [ Time Frame: Per year ]Changes in Framingham risk for CV events (from low to moderate, from moderate to high) based on changes in lipid parameters from baseline at 6, 12, Q12 months after the initiation of a LPV/r based HAART regimen in female subpopulation. Participants will be followed for an average of 24 months .
Secondary Outcome Measures:
- All cause mortality [ Time Frame: Per year ]Overall mortality (including CV events) in HIV- infected subjects treated with a LPV/r as second line and EFV and LPV/r first line based HAART regimen in the whole population under study. Participants will be followed for an average of 24 months .

Detailed Description:
Study design and duration: Retrospective comparative study. Estimated time of enrollment: 12 months.
Procedure: Retrospective review of clinical charts: LPV/r (n = 100) and EFV (a randomly selected representative sample of patients under EFV treatment: 200 patients approximately.). Each patient can only be included in one arm of the study (cannot switch EFV to LPV/r or from LPV/r to EFV)
Subject population
LPV/r (n = 100) and EFV (a randomly selected representative sample of patients under EFV treatment: 200 patients approximately.). Each patient can only be included in one arm of the study (cannot switch EFV to LPV/r or from LPV/r to EFV)
Study Objectives:
Primary Objectives
1)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 Secondary Objectives
- Risk assessment hazard of CV events in HIV- infected subjects treated with a LPV/r as second line and EFV and LPV/r first line based HAART regimen in the whole population under study and in the female and male subpopulations.
- Assessment for 10- year risk of developing hard cardiovascular events (myocardial infarction and coronary death) in HIV- infected subjects treated with a LPV/r ( 1° o 2° line) and EFV first line based HAART regimen
- Overall mortality (including CV events) in HIV- infected subjects treated with a LPV/r as second line and EFV and LPV/r first line based HAART regimen
- Evolution of lipid profile (total cholesterol, HDL, LDL and triglicerides) and lipid lowering agents requirement: baseline vs. 48 weeks after the initiation of a LPV/r second line based HAART regimen and those on an LPV/r and EFV first line based HAART regimen
- Assesment of CD4 T-cell count and viral load at baseline and at 48 weeks in each regimen.
Eligibility| Ages Eligible for Study: | 18 Years and older (Adult, Senior) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
| Sampling Method: | Probability Sample |
Study Population
HIV-infected patients with first line HAART with EFV or LPV/r or second line HAART with LPV/r
Criteria
Inclusion criteria
- HIV positive patients (confirmation with ELISA + W. blot required).
- Age ≥ 18 years.
- Naïve or experienced with antiretroviral drugs.
- LPV/r or EFV as first line regimen.
- In patients with a LPV/r second line HAART regimen, prior exposure to any NNRTI regimen is acceptable.
- Time of exposure to LPV/r or EFV of at least 48 weeks.
Exclusion criteria:
- Age < 18 yrs.
- Already LPV/r treatment at admission in our institution (that prevents assessment of baseline lipid profile and CV risk when patient receives the "first dose" of either LPV/r )
