Exploration of HIV Reservoirs

Completed
Conditions
HIV-1 Infection
Interventions
Procedure: Rectal mucosa biopsy
Registration Number
NCT01019044
Lead Sponsor
Objectif Recherche Vaccins SIDA
Brief Summary

Prospective study in HIV-1 infected patients with a plasma viral load below the limit of detection and stable for at least 5 years.

Detailed Description

Evaluation of the mucosal HIV reservoirs (HIV-DNA quantification and distribution of the infected T lymphocytes in the gut mucosa associated lymphoid tissue compared to the blood in HIV-1 infected patients under antiretroviral treatment with an undetectable plasma viral load below the 50 copies/ml limit of detection for at least 5 years).

Recruitment & Eligibility

Status
COMPLETED
Sex
All
Target Recruitment
11
Inclusion Criteria
  • HIV-1 documented infection
  • HIV-1 plasma viral load measurable before antiretroviral treatment initiation
  • Patients treated with an antiretroviral combination containing a protease inhibitor and/or a non-nucleosidic reverse transcriptase inhibitor without any interruption since treatment initiation
  • Patients with a stable plasma viral load below the limit of detection (HIV-RNA < 50 copies/ml since January 2006 and/or HIV-RNA < 200 copies/ml during the anterior period) under antiretroviral treatment for at least 5 years and for at least 90 % of the measures
Exclusion Criteria
  • Contraindication to the biopsy
  • No ability or willingness to provide informed consent
  • Concomitant treatment with antithrombotics or platelets antiaggregatory
  • Patients co-infected with HCV and or HBV
  • Patients who received an immunosuppressive treatment during 3 months prior enrollment (chemotherapy, radiotherapy, corticotherapy, splenectomy) or an immunotherapy during 5 years prior enrolment (IL-2, anti-HIV vaccine, IFN-alpha)
