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 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Quantification of the HIV proviral DNA in the rectal mucosa biopsies and in the PPBMCs [ Time Frame: Single patient visit ] [ Designated as safety issue: No ]
Quantitative, phenotypic and functional description of the long-term immune reconstitution in the rectal mucosa biopsies [ Time Frame: Single patient visit ] [ Designated as safety issue: No ]
Quantification of HIV proviral DNA in the total CD4 lymphocytes [ Time Frame: Single patient visit ] [ Designated as safety issue: No ]
Pharmacokinetics of the antiretroviral molecules in the rectal mucosa biopsies and in the blood [ Time Frame: Single patient visit ] [ Designated as safety issue: No ]

Biospecimen Retention: None Retained

Plasma and total blood samples A maximum of 15 rectal mucosa biopsy samples


Enrollment:	11
Study Start Date:	May 2009
Study Completion Date:	November 2009
Primary Completion Date:	October 2009 (Final data collection date for primary outcome measure)

Groups/Cohorts	Assigned Interventions
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).

Eligibility


Ages Eligible for Study:	18 Years and older (Adult, Senior)
Genders Eligible for Study:	Both
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)
