The Effects of Anti-HIV Drugs in HIV-Infected Patients Who Do Not Have AIDS
A Multicenter, Open-Label Study of Viral Burden in Peripheral Blood Versus Lymphoid Tissue Before and After Antiretroviral Therapy in HIV-Infected Individuals Without AIDS (NOTE: One Arm Receives no Treatment)

Immunopathogenesis objectives: To compare and quantitatively determine HIV burden and HIV replication in peripheral blood (PB) and lymphoid tissue (LT). To determine the degree to which antiretroviral therapy alters HIV replication in LT.

Clinical objectives: To gain insight into the degree of correlation between immunologic surrogate markers for HIV disease (e.g., CD4, beta-2 microglobulin) as compared to measures of HIV replication in PB and LT. To assess changes in PB and LT viral burden after antiretroviral therapy and to determine its ability to predict an antiviral response.

One of the major problems in defining the immunopathogenic changes in HIV infections has been the inability to correlate the extent of loss of immunologic function with the number of HIV-infected CD4+ cells in the peripheral blood. Few studies exist that measure viral burden in lymph nodes of HIV-infected individuals. Researchers hope to find out whether the amount of HIV virus or markers for the virus in the body's lymph tissue is a better measure of disease progression than the amount of virus or markers for the virus in the blood.

Sixteen antiretroviral-naive patients are randomized to either remain antiretroviral-naive (no treatment) or receive zidovudine daily (treatment). Additionally, 16 patients with 26 or more weeks of ongoing zidovudine (AZT) therapy are randomized to either continue on their prestudy AZT regimen or add didanosine (ddI) daily to their baseline AZT dose. Patients remain on their assigned treatment arms for 8 weeks. A lymph node biopsy is performed on day 0 and at week 8. Patients are evaluated at weeks 2, 4, 6, 8 and 9.

Inclusion Criteria

Concurrent Medication:

Allowed:

  • Chemoprophylaxis against M. tuberculosis, therapy for oral candidiasis, and short courses (up to 10 days) of acyclovir for herpes lesions.
  • Antibiotics as clinically indicated.
  • Pneumococcal vaccine and hepatitis B vaccine as medically indicated.
  • Regularly prescribed medications such as antipyretics, analgesics, allergy medications, antidepressants, sleep medications, oral contraceptives, or other medications deemed appropriate by the patient's primary care provider.

Recommended:

  • PCP prophylaxis if patient's CD4 count falls below 200 cells/mm3 during the study.

Concurrent Treatment:

Allowed:

  • Alternative therapies such as vitamins and acupuncture.

Patients must have:

  • Documented HIV infection.
  • At least two palpable lymph nodes above the waist.
  • CD4 counts >= 350 cells/mm3 (if previously antiretroviral-naive) or >= 250 cells/mm3 (if receiving ongoing AZT therapy).

Patients with prior AZT therapy must have received a stable dose of 300-600 mg daily for 26 or more weeks.

Prior Medication:

Required in patients with prior ongoing therapy:

  • AZT at dose of 300-600 mg daily for at least 26 weeks.

Exclusion Criteria

Patients with the following symptoms and conditions are excluded:

  • Severe malabsorption.
  • Current AIDS-related opportunistic infection, AIDS dementia, AIDS-wasting syndrome, or an AIDS-related malignancy other than minimal Kaposi's sarcoma disease.
  • Current medical problems that may interfere with the evaluation of AZT or increase the potential toxicity of AZT (e.g., significant liver disease, diabetes, significant cardiovascular disease, seizure disorders, lymphoma, acute or chronic pancreatitis, or febrile illness).
  • Current diagnosis of malignancy for which systemic therapy would be required during study.

Concurrent Medication:

Excluded:

Patients with the following prior conditions are excluded:

  • Prior AIDS-related opportunistic infection, AIDS dementia, AIDS-wasting syndrome, or an AIDS-related malignancy other than minimal Kaposi's sarcoma disease.
  • History of medical problems that may interfere with the evaluation of AZT or increase the potential toxicity of AZT (e.g., significant liver disease, diabetes, significant cardiovascular disease, seizure disorders, lymphoma, acute or chronic pancreatitis, or febrile illness).
  • History of peripheral neuropathy (patients with prior AZT treatment only).

Prior Medication:

Excluded:

  • Prior ddI therapy.
  • Less than 26 weeks of prior AZT (in patients with ongoing AZT therapy only).
