Brief Summary:
The purpose of this study is to monitor patients who have recently been infected with HIV in order to learn how their immune systems respond to HIV infection and to study how the virus multiplies in their bodies
Patients who have been infected with HIV recently are considered to have acute or early HIV infection During this period viral load level of HIV in the body rises sharply to a high level at first but then decreases significantly on its own Doctors are not sure why this decrease in viral load happens and how the body is able to accomplish this In this study patients with acute HIV infection will be monitored so that doctors can study their immune systems to try to learn more about this rise and fall in viral load

Detailed Description:
Two theories offer possible explanations for the early decline of viral loads seen in acute HIV infection The first is that CD4 target cell numbers are depleted so the reduction in permissive target cells limits viral replication A second is that the host develops an HIV-specific cytotoxic T lymphocyte CTL immune response that limits viral replication during the initial high viral titer Consequently enhanced clearance of HIV-infected cells results in a decline of plasma HIV RNA This study examines the latter theory by characterizing viral and immune dynamics in the blood and lymph nodes of HIV-infected patients
Cohort I HIV-negative volunteers At study entry a medical history and physical exam is performed and volunteers complete a questionnaire Blood samples are drawn weekly until Week 12 then at Weeks 14 16 20 and 24 Volunteers are followed for 24 weeks Volunteers are offered the opportunity to participate in a lymphoid tissue substudy which involves one to four sequential gut-associated lymphoid biopsies Compensation for travel and for the inconvenience of study participation is provided
Cohort II At study entry a patient history and physical exam is performed and volunteers complete a questionnaire Volunteers with a rising plasma HIV RNA during the first three visits will have frequent sampling of blood and physical exams for two years Volunteers continue to be followed thereafter once every 6 months through 5 years of study duration Volunteers are offered the opportunity to participate in a lymphoid tissue substudy andor the lymphoid kinetics substudy These substudies require hospitalizations of 24 hours or less for tissue biopsies and glucose infusion Compensation for travel and for the inconvenience of study participation is provided
