What this Trial Is About

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.

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:

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).
