It will also explore whether immune system damage caused by HIV can be repaired after new virus replication is stopped with treatment.\n\nHIV-infected patients 18 years of age and older may be eligible for this study, which will include three groups as follows. Candidates will be screened with a medical history, physical examination, blood and urine tests and possibly chest X-ray and electrocardiogram.\n\nParticipants will be divided into three groups according to CD4 count levels: \\> 500 cells/microliter of blood; between 300 and 500 cells/microliter, and \\< 300 cells/microliter of blood. All participants will be treated with a combination of four antiretroviral drugs: indinavir, zidovudine, lamivudine and nevirapine. (Exceptions to this regimen may be made in certain circumstances for patients who cannot tolerate one of the four drugs.) In addition, they will undergo the following procedures:\n\nBlood tests - Blood tests will be done at screening and at study entry to evaluate the patient's health status and measure CD4 T cell count and plasma HIV levels; at the beginning of treatment to look for drug-related side effects; and during the course of the study to evaluate drug effectiveness in inhibiting HIV replication; CD4 T cell levels and function.\n\nLymph node biopsy - Lymph node biopsies are done under local anesthesia. A small incision is made, the node is removed, and the incision is closed with stitches. Up to two nodes may be removed during each procedure. Patients with CD4 counts greater than 500 cells/microliter of blood and those with counts less than 300 cells/microliter will have three lymph node biopsies in order to 1) assess the effectiveness of therapy in inhibiting HIV replication in the nodes (the major site of replication); 2) determine how long HIV-infected cells may persist in the nodes after new replication is stopped by therapy; and 3) determine if immune damage caused by HIV can be repaired when virus replication is stopped. Lymph node biopsy in patients with counts between 300 and 500 cells/microliter of blood is required only at baseline, although follow-up biopsies are encouraged.\n\nLeukapheresis - In this procedure, whole blood is collected through a needle placed in an arm vein. The blood circulates through a cell separator machine where the white cells are removed and collected. The rest of the blood is returned to the body, either through the same needle used to draw the blood or through a second needle placed in the other arm. The collected white cells are used for special studies of the level and function of T cells before and after drug treatment. Patients with CD4 counts \\> 500 cells/microliter and \\< 300 cells/microliter will undergo leukapheresis up to four times - at study entry and about 2, 6 and 12 months after starting antiretroviral therapy. Patients with CD4 counts between 300 and 500 cells/microliter will have this procedure either at study entry and 6 and 12 weeks after initiation therapy, or on the same schedule as the other patients.", "detailedDescription"=>"The reservoirs of HIV-1 infection that permit maintenance of persistent virus infection (even when virus replication cannot be detected using sensitive assays to quantify plasma HIV-1 RNA levels) are currently unknown. Potential sites for persistent HIV-1 infection include cells with chronic or latent infections, cells present in locations within the body where antiviral drugs may not penetrate in levels sufficient to prevent additional cycles of de novo virus infection (e.g., the central nervous system), the presence of susceptible target cells for virus infection that may not metabolize certain antiviral drugs to their active inhibitory forms (e.g., macrophages), or extracellular (possible infectious) virus that may be retained on the surface of follicular dendritic cells within lymphoid organs. In an attempt to determine which, if any, of these potential reservoirs contribute to persistent HIV-1 infection, HIV-1-infected persons in two groups categorized by CD4+ T cell levels will be treated with concomitant administration of 4 antiviral drugs (zidovudine, lamivudine, indinavir and nevirapine) to accomplish maximal achievable suppression of virus replication. The rates of decay of virus and virus-infected cells following initiation of antiviral (and steroid) therapy will be monitored with sensitive, quantitative assays, and the identity and longevity of persistent sites of infection will be determined. This study may also illuminate to what extent HIV-1-induced immune system damage manifest as decreased CD4 T cell responses, a constricted repertoire of T cell antigen recognition, or as structural compromise of lymphoid tissue architecture can be reversed upon cessation of active HIV-1 replication by combinations of potent antiviral drugs."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "minimumAge"=>"18 years", "healthyVolunteers"=>false, "eligibilityCriteria"=>"* INCLUSION CRITERIA:\n\nGreater than or equal to 18 years old.\n\nAbility to sign informed consent and willingness to comply with study requirements and clinic policies.\n\nFor women of child-bearing potential, negative result on pregnancy test within one week prior to initiating therapy.\n\nNo medical contraindication to lymph node biopsy.\n\nHIV infection confirmed by ELISA and Western blot.\n\nTwo CD4+ T cell counts less than 300/microliters within 3 months of beginning the protocol, with one of the two counts obtained at a screening history and physical examination performed 2 weeks prior to initiating therapy.\n\nPlasma HIV-1 RNA levels greater than 8000/ml.\n\nFor participants with CD4 T cell counts greater than or equal to 300/microliter, asymptomatic for significant HIV-related illnesses.
