  • Systemic maintenance therapy for AIDS-defining opportunistic infection.
  • Recombinant erythropoietin.
  • Long term therapy with either aspirin or probenecid.

Concurrent Treatment:


Blood transfusion more than once per month.

Patients with the following are excluded:

  • Symptomatic visceral Kaposi's sarcoma or progression of Kaposi's sarcoma within the month prior to study entry.
  • Unwilling to sign an informed consent or patients unwilling to be followed at the medical center where they were enrolled for the duration of the study and follow-up as required.
  • History of intolerance to zidovudine (AZT) at any dose as demonstrated by an AZT related decrease in hemoglobin levels of at least 2 g/dl or AZT related depression of neutrophils of at least 200 cells/mm3 to < 750 cells/mm3 which required discontinuation of AZT therapy.
  • Diseases or conditions listed in Exclusion Co-Existing Conditions.

Prior Medication:


  • Antiretroviral agents within 14 days of study entry.
  • Immunomodulating agents or corticosteroids within 30 days prior to study entry.
  • Treatment for acute Pneumocystis carinii pneumonia within 2 weeks prior to study entry.

Prior Treatment:
