Abstract

Objective: To determine the association of cytomegalovirus (CMV) viremia with mortality and CMV retinitis progression in newly diagnosed and relapsed CMV retinitis. Design: Ancillary study of a randomized, placebo-controlled, phase III clinical trial. Patients: A total of 83 patients with AIDS and CMV retinitis, enrolled during the first phase of the Monoclonal Antibody Cytomegalovirus Retinitis Trial, were administered MSL-109 or placebo as adjuvant therapy for CMV retinitis. Main outcome measure(s): Mortality and CMV retinitis progression. Results: Treatment with MSL-109 did not predict either progression of CMV retinitis or mortality. Detection in plasma CMV DNA at baseline predicted mortality, but CMV antigenemia did not. CMV DNA was a better predictor of mortality than a high HIV viral load. Neither CMV DNA nor antigenemia predicted the progression of CMV retinitis. Among newly diagnosed patients, there was a decline in the proportion with detectable CMV viral load and CMV antigenemia in response to anti-CMV therapy. However, there was a rebound in CMV viral load to 25% and CMV antigenemia to 54.6% at 6 months. In relapsed patients, anti-CMV therapy was not associated with a change in the percentage with detectable CMV-DNA or CMV antigenemia over time. Conclusion: In patients with AIDS and CMV retinitis, the detection of plasma CMV DNA was associated with a higher risk of mortality than was a high HIV viral load. Anti-CMV therapy provided a transient reduction in CMV viremia in newly diagnosed but not relapsed patients with CMV retinitis. Adjuvant therapy with MSL-109 was ineffective in clearing CMV-DNA and CMV antigen from the plasma.
