Abstract

The suppression of human immunodeficiency virus (HIV) replication and elevation in CD4 cells observed with protease inhibitor combination regimens known as HAART (highly active antiretroviral therapy) may allow AIDS patients to undergo an immune recovery that allows them to suppress the progression of cytomegalovirus (CMV) retinitis. Eleven AIDS patients receiving HAART with healed CMV retinitis in whom CMV-specific maintenance therapy was discontinued were studied. Median CD4 cell counts were 42 before the initiation of HAART and 183 at discontinuation of anti-CMV therapy. While a median 1.1 log10 drop in plasma HIV-1 RNA was obtained between starting HAART and withdrawal of maintenance therapy for CMV, only 3 of 11 patients maintained plasma HIV RNA below the limits of detection. Reactivation of CMV retinitis after withdrawal of anti-CMV therapy did not occur in any of the patients observed for a median of 156 days (range, 92-558).
