Background In the advanced stages of the acquired immunodeficiencysyndrome (AIDS), cytomegalovirus (CMV) disease, particularlyvision-damaging retinitis due to CMV, is common. We evaluatedprophylactic treatment with orally administered gancicloviras a way to prevent CMV disease.
Methods We conducted a prospective, randomized, double-blind,placebo-controlled study of CMV-infected persons with AIDS witheither CD4+ lymphocyte counts of <50 per cubic millimeteror counts of <100 per cubic millimeter in those with a historyof an AIDS-defining opportunistic infection. Patients were randomlyassigned, in a 2:1 ratio, to receive either oral ganciclovir(1000 mg three times daily) or placebo.
Results The study was stopped after a median of 367 days offollow-up. In an intention-to-treat analysis, the 12-month cumulativerates of confirmed CMV disease were 26 percent in the placebogroup (n = 239) and 14 percent in the ganciclovir group (n =486), representing an overall reduction in risk of 49 percentin the ganciclovir group (P<0.001). The incidence of CMVretinitis after 12 months was 24 percent in the placebo groupand 12 percent in the ganciclovir group (P<0.001). The prevalenceof CMV-positive urine cultures at base line was 42 percent;after two months it was 43 percent in the placebo group and10 percent in the ganciclovir group (P<0.001). The one-yearmortality rate was 26 percent in the placebo group and 21 percentin the ganciclovir group (P = 0.14). Therapy with granulocytecolony-stimulating factor was more frequent in the ganciclovirgroup (24 percent) than in the placebo group (9 percent).
Conclusions In persons with advanced AIDS, prophylactic oralganciclovir significantly reduces the risk of CMV disease.
