Eligibility Criteria
Inclusion Criteria Concurrent Medication: Allowed: Prophylactic therapy for Pneumocystis carinii pneumonia (PCP); aerosol pentamidine is the preferred method. Maintenance anticonvulsant therapy following a seizure in the context of the AIDS dementia complex. Patients taking anticonvulsants should have their anticonvulsant blood levels measured prior to starting zidovudine (AZT) or with changes in AZT dosage. Phenytoin, carbamazepine, and valproic acid. Judicious use of benzodiazepams. For analgesia or fever, modest doses of aspirin, Tylenol, or ibuprofen. Use of major mood or central nervous system altering drugs is discouraged and should be documented. Patients with the following are included: An estimated pre-illness IQ = or > 70. A general neurodiagnostic evaluation before entry which will include a computerized tomographic (CT) scan or magnetic resonance imaging (MRI) scan and a lumbar puncture. Stable or indolently progressive mucocutaneous Kaposi's sarcoma with < 25 lesions and onset of < 10 new lesions during the 30-day period prior to study entry. Chronic seizure disorders requiring anticonvulsant therapy as long as the seizures are not associated with a fixed neurologic deficit. A blood HIV culture and p24 antigen capture assay at the time of the lumbar puncture. A second p24 antigen assay on study entry. Informed consent form must be signed by the patient, legal guardian, or parent. Active substance abuse that would limit a patient's cooperation or evaluation. Exclusion Criteria Co-existing Condition: Patients with the following will be excluded from the study: Active, symptomatic AIDS-associated opportunistic infections requiring ongoing maintenance therapy. Persistent fever, active persistent diarrhea, or continued severe weight loss. Severe premorbid psychiatric illness. Confounding neurologic disease or deficit. Concurrent or previous central nervous system infections or neoplasms. Concurrent active neoplasms other than basal cell carcinoma of the skin and mucocutaneous Kaposi's sarcoma. Concurrent Medication: Excluded: Major psychotropic medication including tricyclic antidepressants, MAO inhibitors, phenothiazines, butyrophenones, barbiturates, or amphetamines. Cimetidine. Ranitidine. Probenecid. Indomethacin. Acyclovir (ACV) prophylaxis for recurrent Herpes simplex. Patients with the following will be excluded from the study: Active, symptomatic AIDS-associated opportunistic infections requiring ongoing maintenance therapy. Persistent fever, active persistent diarrhea, or continued severe weight loss. Severe premorbid psychiatric illness. Confounding neurologic disease or deficit. Concurrent or previous central nervous system infections or neoplasms. Concurrent active neoplasms other than basal cell carcinoma of the skin and mucocutaneous Kaposi's sarcoma. Prior Medication: Excluded within 2 weeks of study entry or for greater than 2 weeks of therapy: Zidovudine (AZT). Patients must not have previously exhibited toxic reaction to AZT. Excluded within 30 days of study entry: Immunomodulators and biologic response modifiers, including systemic steroids. Any investigational agent. Cytotoxic chemotherapy for Kaposi's sarcoma. Prior Treatment: Excluded within 30 days of study entry: Radiation therapy. Excluded within 2 weeks of study entry: Blood transfusion.
