Estimated Enrollment:
1100

Detailed Description:

The Multicenter AIDS Cohort Study (MACS) provides important information about the changing nature of HIV-mediated disease progression, the impact of antiretroviral treatment, the nature of HIV pathogenesis, and viral and host genetic factors. This study will also assess the long-term patterns of therapy use and risk-taking behaviors.

Patients will have study visits every 6 months. The visits will include interviews, specimen collection, and a physical examination.

  Eligibility
Ages Eligible for Study:
18 Years and older
Genders Eligible for Study:
Male
Accepts Healthy Volunteers:
No
Criteria

Inclusion Criteria:

  • HIV negative, or
  • HIV positive and no history or current use of highly active antiretroviral therapy (HAART), or
  • HIV positive HAART recipient with documentation of HAART initiation, no AIDS diagnosis prior to HAART initiation, and a CD4 cell count and HIV-1 RNA measurement within 6 months prior to first HAART use.
  • Sexual intercourse with men or at least 5 male or female partners in the 5 years prior to enrollment.

Exclusion Criteria:

  • Injection drug use within 1 year of enrollment.
  • Perinatally acquired HIV infection.
