Description

Hematologic abnormalities occur with high frequency (up to 70% of patients) in human immunodeficiency virus (HIV) infected individuals. The pathogenesis of these abnormalities is not currently understood, although both an abnormal bone marrow environment (e.g., altered growth factor production) and direct infection and dysfunction of progenitor cells themselves have been postulated. Under the current protocol we have studied bone marrow precursor cells from both HIV infected and uninfected individuals and have shown not only that these cells are infectable in vitro with HIV but also infecte...

Eligibility criteria

  • INCLUSION CRITERIA:
  • Both HIV seropositive and seronegative individuals.
  • Have adequate blood counts (HIV positive volunteers: hemoglobin greater than or equal to 9.0 g/dL, HCT greater than or equal to 28%, platelets greater than or equal to 50,000; HIV negative healthy normal volunteers: hemoglobin greater than or equal to 12.5 g/dL, HCT greater than or equal to 38%, platelets greater than or equal to 150,000.
  • Aged 18 years or older, male or female.
  • Ability to give informed, written consent.
  • This protocol was amended in 1990 to allow inclusion of Zairian patients who were studied by the principal investigator on site in Zaire. These marrow aspirations were all performed in March-April 1990 before the current requirements for Multi-site Collaborations were instituted. At this time, no further off-site collaboration will be undertaken under this protocol.
  • EXCLUSION CRITERIA:
  • Women who are pregnant.
  • Patients/volunteers with blood clotting disorders as demonstrated by an elevated PT, PTT or low platelet count (Seropositive: platelets greater than or equal to 50,000; Seronegative: platelets greater than or equal to150,000.
  • Patients/Volunteers who are taking NSAIDS or other anti-coagulant medication.
