|---|---|
| Main Objective: 1. To describe and compare the kinetics of immune recovery degree and quality in advanced naive HIV-infected individuals (CD4+ 50-150 cells/&#61549;l) starting as first regimen an EFV-based HAART regimen compared to ?less advanced? patients (CD4+>250 cells/&#61549;l) 2. To thoroughly characterise the role and kinetics of specific immune parameters in immune reconstitution following EFV-based HAART;Secondary Objective: 1. To describe the kinetics of HIV-RNA decay in plasma of patients of the two groups 2. To describe the kinetics of intracellular HIV DNA in total peripheral blood CD4;Primary end point(s): The primary efficacy variables of the study are: - proportion of subjects who have a CD4+ T cell number increase > 20% after 24 weeks of EFV-based HAART; - changes from baseline of peripheral CD4+ and CD8+ T-cell activation and proliferation rates; - changes from baseline of peripheral CD4+ and CD8+ apoptosis rate; - changes from baseline of levels and function of interleukin-7 (IL-7) and interleukin-15 (IL-5), as T-cell homeostasis cytokine regulators; - frequency of circulating HIV-specific IFN-&#61543; and IL-2 producing T-cells; - frequency of circulating HIV-specific CD8+ IFN-&#61543; ELISPOT responses; - frequency of circulating T-regulatory CD4+ T cells (Treg); - changes from baseline of patterns of CD4 and CD8 T-cell maturation | — |
