AIDSに合併したCMV網膜炎患者11例にガンシクロビルを全身投与した。初期療法(10mg/kg週7回投与)により7例に網膜炎の完全な鎮静化を,3例に部分的な鎮静化を認めた。1例は治療に反応しなかったため,foscarnetを併用し部分的な鎮静化を得た。しかしその後維持療法中に網膜病変の拡大や新病変の出現を10例中3例に認めた。ガンシクロビルの副作用である骨髄抑制のためすべての症例に白血球減少を認め,1例で治療の中断を余儀なくされた。ガンシクロビルの全身投与はCMV網膜炎に効果のある治療であったが,長期にわたる継続治療が必要であった。
Eleven patients with acquired immune deficiency syndrome (AIDS) developed cytomegalovirus retinitis. They were treated with intravenous ganciclovir. During the induction therapy, retinitis improved completely in 10 patients and partially in 3. In one patient who failed to respond to ganciclovir, intravenous foscarnet and ganciclovir resulted in partial resolution. Retinitis recurred in 3 of the 10 patients during the maintenance therapy, necessitating further reduction therapy. All cases developed leukopenia induced by ganciclovir. The treatment had to be discontinued in one patient resulting in extensive retinal involvements and optic atrophy. While intravenous ganciclovir appeared to be effective for cytomegalovirus retinitis in patients with AIDS, longterm maintenance therapy was necessary under careful hematological monitoring.
