Age group | N/A and older |
Eligibility |
Blood samples from 5 cohorts of HIV infected individuals and 2 cohorts of HIV uninfected
individuals will be evaluated. Varying stages of HIV disease are represented in these cohorts, including: - Individuals who have been exposed but who have not seroconverted - Individuals who have recently seroconverted - HAART-treated patients who receive immune modulators such as IL-2 and therapeutic immunization - HAART-treated patients who undergo structured treatment interruptions - HAART-treated patients who have durable suppression of viremia - HAART-treated patients who experience incomplete suppression of viremia - HAART-treated patients followed with careful drug adherence monitoring - Long-term nonprogressors - Untreated progressors |
