Patients begin antiretroviral therapy within 7 days of enrollment. All patients are evaluated for treatment compliance and complete a compliance questionnaire regularly. Clinical evaluations, including CD4, CD8, and HIV RNA counts also are done regularly. Antiretroviral therapy is discontinued if there is no detectable virus by ultrasensitive assay and culture techniques in plasma, PBMCs, and lymphoid tissue. In a subset of patients, genital secretions and CSF (cerebrospinal fluid) are evaluated. If relapse occurs, antiretroviral therapy is re-instituted. In addition, virology and immunology substudies are performed.
