[Innate immunity restoration in patients with HIV/AIDS infection associated with antiretroviral therapy].

Background: Highly active antiretroviral therapy (HAART) in HIV/AIDS infection induces an important reduction of the viral load (VL) and an immune system reconstitution. CD4+ T lymphocyte count is the immunological measurement commonly used for the follow up of HIV/AIDS patients.

Aim: To study prospectively the restoration of the innate immune system in patients with HIV/AIDS infection during their first year on HAART.
