Purpose
Suboptimal improvement in cluster of differentiation 4 (CD4) cell count is not uncommon in HIV-1-infected patients with suppressed plasma HIV-Ribonucleic acid (RNA) levels, and a decrease in CD4 cell count in patients with suppressed or low level viremia has been observed.
Although the efficacy of current antiretroviral medications is well established, some antiviral combinations are very effective in suppressing HIV-1 load whereas do not exert any effect on immune reconstitution.
Both T-cell immune activation and fibrosis of peripheral lymphoid tissue could create an environment in which CD4 T cell count decrease in the setting of low or suppressed plasma viremia is likely to occur.
Another fascinating hypothesis, which has still to be elucidated, is that reconstitution of the depleted CD4 pool is blocked by an excess of glycoprotein 120 (gp120) HIV-1 protein. This extra-production could be counteracted by an inhibitor of the chemokine (C-C motif) receptor 5 (CCR5) co-receptor that represents one of the major docking tools of HIV-1.
With this in mind, the investigators would like to propose and design a pilot exploratory clinical trial involving a population of HIV-1-infected patients that rapidly reached a virologic suppression without a reconstitution of their immune system.

Detailed Description:
Objectives:
- Evaluate the clinical efficacy of HAART intensification with MVC as treatment of HIV-1 infection in patients with a CD4 count ≤ 200 cells/uL and/or a recovery of CD4 cells < 25% compared to the HAART initiation and with a complete and stable virologic suppression after 12 months of HAART. Patients could also being included if their CD4 slope has been stable without any improvement, with an absolute value around 200 cells/uL.
- Evaluate the effects of HAART intensification with MVC on the modification of immunologic and virologic parameters.
- Evaluate the tolerability of HAART intensification with MVC and the appearance of drug-related side effects.
Design:
This will be a randomised, multicenter, study that will evaluate HAART intensification with MVC as treatment of HIV-1 infection in patients with a CD4 count ≤ 200 cells/uL and/or a recovery of CD4 cells < 25% compared to the HAART initiation and/or a stable CD4 slope without any improvement, with an absolute value around 200 cells/uL and with a complete and stable virologic suppression after 12 months of HAART.
