Brief Summary
Open, prospective, multicenter French cohort study enrolling subjects aged of 15 years or more, during or immediately after HIV-1 primary infection. This cohort was organized from the outset to be highly multidisciplinary, bringing together immunologists, virologists, clinicians and epidemiologists.

Outcome Measures
Primary Outcomes (1)
Improve the physiological, pathological and virological knowledge of primary HIV infection
* Study of the immune mechanisms involved early after infection * Kinetics of viral replication and establishment of cellular reservoirs at an early stage * Relationships between virological markers and immune response kinetics * Impact of resistance mutations, subtype and tropism on the disease progression and the response to treatment * Study of sub-groups of specific patients followed since primary infection, spontaneous or post treatment controllers, subjects with specific HLA
up to 25 years
Secondary Outcomes (3)
The impact of early, transient or prolonged treatment versus deferred treatment on the long-term prognosis of patients followed since primary infection, in terms of activation / inflammation
up to 25 years
Contribute to knowledge in the epidemiology of HIV infection
up to 25 years
Contribute to national recommendations for therapeutic care and evaluate their implementation
up to 25 years
Study Arms (1)
Follow-up Arm
Blood sampling only
Interventions
Blood Sampling at J0, M1, M3, M6, M12, M24 and every 12 months until the end of the study
Eligibility Criteria
HIV-1 infected patients
You may qualify if:
- symptomatic or asymptomatic HIV-1 primary infection.
- Infection date based on one of the following criteria:
- Positive p24 antigenemia or detectable plasma HIV RNA with a negative ELISA within the previous six weeks.
- Positive p24 antigenemia or detectable plasma HIV RNA with a positive ELISA and negative Western Blot within the previous six weeks.
- Positive p24 antigenemia or detectable plasma HIV RNA or positive ELISA with incompleted Western Blot (no anti-p34 and/or anti-p68) within the previous six weeks.
- Positive ELISA with a negative ELISA within the last three months.
- Age≥ 15 years old at the enrollment.
- Naive of antiretroviral treatment except for transient treatment taken in the context of PMTCT, Pre-exposition prophylaxis or Post Exposition Prophylaxis.
- Affiliate or beneficiary of a social security system (State Medical Assistance is not a social security scheme).
You may not qualify if:
- Inability to give informed consent.
- Predictable difficult follow-up.
- Contraindication to repeated blood samples.
- Under protection (saving) of justice
