PRIMARY: To determine the effect of 8 weeks of zidovudine (AZT) treatment on the HIV-1 burden in peripheral blood and lymphoid tissue in HIV-1-infected, AZT-naive patients with CD4+ T lymphocyte counts between 100 and 500 cells/mm3. SECONDARY: To determine the extent to which apoptosis (programmed cell death) occurs in these patients. In previous trials of AZT treatment in HIV-infected patients, an antiviral effect has been clearly demonstrated by quantitative measurement of virus in plasma and peripheral blood mononuclear cells. However, the lymphoid tissues appear to be a major reservoir for HIV-1 and a major site of virus replication in HIV-infected persons. Further data is needed to assess the effect of treatment on viral burden and HIV-1 replication in lymphoid tissue.

Further data is needed to assess the effect of treatment on viral burden and HIV-1 replication in lymphoid tissue. Patients receive AZT daily for 8 weeks and are followed in clinic at weeks 2, 4, 6, 8, 9, and 14 (or possibly via telephone call at week 14). Patients undergo a lymph node biopsy at day 0 and week 8.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
18 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.
