详细说明

The study involves a one-time collection of health and medical history data, blood and urine specimens, and physical assessments. This study will elucidate the need for a further in-depth study to understand the pathophysiological effects of protease inhibitor (PI)-based and non-nucleoside analogue reverse transcriptase inhibitor (NNRTI)-based therapies in young men.

  • Males age 12 years and 0 days through 24 years and 364 days.
  • Tanner stage 4 or 5.
  • Accessible medical history and medications history.

  • Willingness and ability to give informed consent or assent with parental/legal guardian permission, where required.

Group 1: HIV-Negative Control Subject Specific Inclusion Criteria

  • All subjects for Group 1 will be tested for HIV-1 to confirm negativity unless they have a documented negative antibody test within the last three months of study entry.
  • Willingness and ability to give informed consent for HIV testing. Groups 2, 3, and 4: HIV-Positive Subject Specific Inclusion Criteria
  • HIV-1 infection as documented by a positive result on any of the following licensed tests at any time: any antibody test confirmed by Western blot, HIV culture, plasma HIV-1 RNA PCR >1,000 copies/ml or HIV-1 DNA PCR.
  • Horizontal HIV infection transmission (non-perinatal, non-transfusion acquired infection).
  • Group 2: Currently not on ART and must never have received ART.
  • Group 3: Currently on a NNRTI, non-PI containing regimen for three or more months, must never have received a total of more than six months of PI-containing regimen and at least one year must have passed since receipt of last PI-containing regimen.
  • Group 4: Currently on a PI, non-NNRTI containing regimen for three or more months, must never have received a total of more than six months of NNRTI-containing regimen and at least one year must have passed since receipt of last NNRTI-containing regimen.
