Early Control of HIV-1 Infection in Long-Term Nonprogressors Followed Since Diagnosis in the ANRS SEROCO/HEMOCO Cohort

Résumé

Background: To clarify early correlates and natural history of HIV long-term nonprogressors (LTNPs) since HIV diagnosis. Methods: Patients enrolled in the French ANRS SEROCO/HEMOCO cohort with CD4 count >500 cells/mm3 at HIV diagnosis. LTNP status was defined as being asymptomatic, antiretroviral free, and with CD4 cell count >500 cells/mm3 for >8 years after HIV diagnosis. In LTNPs, we modeled the biological markers' progression through a joint model. Factors associated with loss of LTNP status were identified through a Cox model. Results: Sixty (9%) of 664 patients were identified as LTNPs during follow-up. At enrollment, HIV RNA was 1.85 log copies/10(6) PBMCs and high HIV DNA increase were associated with an increased risk of losing LTNP status [adjusted hazard ratio: 2.8 (1.2-6.8) and 2.2 (1.0-4.8), respectively]. Conclusions: LTNP status is established in the first years of HIV infection, low HIV DNA level at enrollment and slow increase of HIV DNA being associated with maintained LTNP status.
