NCT00000709

Brief Summary

To provide accurate and complete neurologic assessment of the course of the AIDS dementia complex in patients treated with zidovudine (AZT). The study will determine how frequently patients improve, how long improvement is sustained, and the magnitude and functional significance of improvement. Individuals with AIDS frequently suffer central nervous system (CNS) problems that are characterized by cognitive, motor, and behavioral deficits, in a disorder known as AIDS dementia complex. Clinical experience suggests that its course is often progressive, going from initial symptoms to moderate or severe dementia within several months. Accumulating evidence now suggests that direct brain infection by the HIV virus is the likely cause of the AIDS dementia complex. Case reports suggest that therapy with AZT, which has been shown to be a strong inhibitor of HIV replication in vitro, may alleviate the AIDS dementia complex. This study will help define the natural history of the AIDS dementia complex in treated patients.

Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • 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.
  • +1 more criteria

You may not qualify if:

  • 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.
