Description

HIV-infected or AIDS patients may develop ADC which causes damage to the nervous system. ADC may be caused by some action of the AIDS virus on the nervous system, although similar problems can be caused by other infections because the AIDS virus lowers the body's ability to fight other infections. It is important to determine whether symptoms are due to ADC or to some other infection since treatment varies for different conditions. AZT has been shown to be beneficial to people with ADC although its effectiveness has only been studied in a small number of patients. Studies suggest that highe...

  • In patients for whom it is medically necessary to initiate or alter therapy with these drugs during the initial 16 week study period, data will not be used in the study.
  • Metronidazole for single courses of therapy not to exceed 14 days within consecutive 90-day intervals, the first of which begins at the initiation of the study.
  • Erythropoietin for patients under the relevant Treatment IND.
  • Symptomatic therapies (such as analgesics, antihistamines, antiemetics, antidiarrheal agents).

  • Estimated premorbid IQ of at least 70.
  • Anti-HIV antibody or HIV in blood and/or cerebrospinal fluid.
  • If prior history of positive syphilis serology, should have been treated with appropriate course of antibiotics; if not, such treatment should be administered prior to pretreatment screening.
  • Not have previously shown intolerance to zidovudine (AZT).
  • Able (or parent and/or guardian able) to provide written consent.

  • Exclusion Criteria
  • Co-existing Condition:
  • Patients with the following conditions or symptoms are excluded:
  • Grade 3 neuropathy, based on the Neuropathy Targeted Symptom.
  • Questionnaire, or patients with any moderate abnormality indicative of peripheral neuropathy including stocking loss of sensation (to sharp pain, light touch, or vibration), distal extremity weakness (< 4/5), or absent ankle jerks.
  • History of present or past acute or chronic pancreatitis.
  • Active, symptomatic AIDS-defining opportunistic infection and requiring any ongoing maintenance therapy for confounding neurologic disease.
  • Severe premorbid psychiatric illness including bipolar illness, schizophrenia, and electroconvulsive therapy.
  • Previous neurological disease unrelated to HIV infection:
  • multiple sclerosis, documented stroke, degenerative disease.
  • Patients with chronic seizure disorders or head injury will only be excluded if the condition results in functional impairment or is likely to interfere with the evaluation.
  • Concurrent or previous central nervous system infections or neoplasms as revealed by Computerized Tomography (CT) or Magnetic Resonance Imaging (MRI) scan or cerebrospinal fluid analysis (such as toxoplasmosis, primary or metastatic Central Nervous System (CNS) lymphoma, progressive multifocal leukoencephalopathy, cryptococcal or other fungal meningitis, tuberculous Central Nervous System (CNS) infections, and untreated neurosyphilis).
  • Concurrent Medication:
  • Excluded:
  • Intravenous pentamidine. DHPG (Ganciclovir) should not be co-administered.

  • Active, symptomatic AIDS-defining opportunistic infection.
  • Requiring any ongoing maintenance therapy for confounding neurologic disease.
  • Conditions listed under Exclusion Co-existing Conditions.
