Dynamics of viral load rebound and immunological changes after stopping effective antiretroviral therapy

Abstract

Discontinuation of HAART after 1 year of successful treatment is followed by a rapid rebound of viral load; this rapidly returns to undetectable levels following reintroduction of the same treatment. In patients with more effective control of virus replication (viremia below 5 copise/ml), discontinuation of treatment was associated with more severe impairment of immunologic parameters.
