Abstract
Disseminated cytomegalovirus (CMV) infection is a common complication of the acquired immunodeficiency syndrome (AIDS) and contributes significantly to its morbidity and mortality. Dihydroxypropoxymethyl guanine, DHPG, is an antiviral agent that has been shown to inhibit CMV replication and to provide clinical benefit in patients with CMV infections, especially retinitis. In this study, the clinical characteristics, results of diagnostic evaluations, and survival were compared in ll AIDS patients with disseminated CMV infections who were seen between August 1981 and October 1984 and were not treated with DHPG, and in 18 AIDS patients seen since that time who were treated with DHPG. The study groups were similar though the untreated group was somewhat more tissue depleted. Survival from diagnosis was significantly prolonged with DHPG therapy based upon life table analysis (p=0.001). Therapy improved the quality of life, as 12 of 18 treated patients and only 2 of ll untreated patients could be discharged from the hospital. Progression of CMV infection did not appear to play a role in the mortality of patients who died during DHPG therapy. We conclude that DHPG prolongs survival in patients with AIDS who have disseminat ed CMV infections.
