Further study details as provided by Objectif Recherche Vaccins SIDA:
Primary Outcome Measures:
- Quantification of the HIV-RNA plasma viral load using ultrasensible assay (limit of detection: 1 copy/ml) [ Time Frame: Single patient visit ]
Secondary Outcome Measures:
- Quantification of the HIV proviral DNA in the rectal mucosa biopsies and in the PPBMCs [ Time Frame: Single patient visit ]
- Quantitative, phenotypic and functional description of the long-term immune reconstitution in the rectal mucosa biopsies [ Time Frame: Single patient visit ]
- Quantification of HIV proviral DNA in the total CD4 lymphocytes [ Time Frame: Single patient visit ]
- Pharmacokinetics of the antiretroviral molecules in the rectal mucosa biopsies and in the blood [ Time Frame: Single patient visit ]
Biospecimen Retention: None Retained
Plasma and total blood samples A maximum of 15 rectal mucosa biopsy samples

Rectal mucosa biopsy
Rectal mucosa samples collection

Procedure: Rectal mucosa biopsy
Collection of a maximum of 15 rectal mucosa samples in the high portion of the rectum near the rectosigmoidal junction
|
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).

| Accepts Healthy Volunteers: | No |
| Sampling Method: | Non-Probability Sample |
Study Population
HIV-1 infected patients followed in specialized infectious disease/HIV hospital department
Criteria
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)
