Immunologic and Virologic Consequences of Long-Term Highly Active Antiretroviral Therapy (HAART) in Subjects With Moderately Advanced HIV-1 Disease: A Follow-Up Study to ACTG 315
Completed · Phase 2
Conditions studied: HIV Infections
In brief
To evaluate the relationship between viral suppression and changes in immune function, as measured by the restoration of delayed-type hypersensitivity (DTH) and lymphoproliferative (LP) responses, observed after 48 weeks of treatment with highly active antiretroviral therapy (HAART) in ACTG 315. To evaluate the durability of the antiviral and immunologic effects of long-term treatment with HAART. Given the extensive immunologic and virologic data available from ACTG 315, follow-up studies of this advanced-disease population are indicated to primarily ascertain the impact of long-term suppression of viral replication on immunologic reconstitution or re-education and the durability of the antiviral effects of HAART.
