简要总结

The purpose of this study is to see whether taking interleukin-2 (IL-2) and other anti-HIV drugs affects the course of HIV disease in patients with primary HIV infection (the time period that immediately follows infection with HIV).

After primary HIV infection, the actual infection is spread through an increasing amount of HIV virus in the body. Studies have shown that, by taking a combination of anti-HIV drugs, it is possible to reduce the amount of HIV in the body to almost undetectable levels. This study will find out if starting anti-HIV drugs during primary infection will interrupt or reduce the spread of HIV in patients' bodies.

详细描述

Following initial exposure to HIV, infection is established through the rapid replication of a homogeneous strain of the virus. Preliminary studies of combination antiretroviral therapy show that it is possible to reduce circulating HIV RNA to below detectable levels at this phase. Sustained suppression of viral replication or viral eradication may be possible only before HIV has become integrated in the immune system and undergone a number of quasi species mutations. This study will assess the feasibility of interrupting the natural course of HIV infection by using antiretroviral therapy soon after initial infection.

Nelfinavir (NFV) and zidovudine/lamivudine (Combivir) treatment starts as soon as possible and at most, 7 days from the diagnosis of HIV infection, and continues for 104 weeks. After 4 weeks of therapy patients are randomized to begin receiving IL-2 therapy or to delay starting it until Week 48. Patients may choose not to receive IL-2 treatment and remain in the study. Patients have clinic visits to measure viral load every 4 weeks. At a final clinic visit, physical examinations and collection of semen, cervical fluid, blood, and saliva specimens are done. Eligible consenting patients have a tonsil biopsy. Patients are reimbursed for participation in this study.
