| Abstract
| - The safety and efficacy of foscarnet for prevention of cytomegalovirus (CMV) infection was evaluated in 19 CMV-seropositive bone marrow transplant (BMT) recipients. All patients received intermittent intravenous (iv) foscarnet: 40 mg/kg every 8 h from 7 days before to day 30 after BMT, then 60 mg/kg once a day until day 75. The main toxicity was transient renal dysfunction, with a >50 µmol/L increase in serum creatinine above baseline in 5 of the 7 autograft recipients and in 6 of the 12 allograft recipients. Only 4 allograft recipients developed CMV infection during foscarnet prophylaxis, and no patient showed evidenceofCMV disease. Because 3 allograft recipients receiving concomitant iv amphotericin B showed rapid impairment of renal function, foscarnet prophylaxis should not be given to allograft recipients requiring amphotericin B; otherwise, foscarnet prophylaxis at this dose appears safe after BMT.
