Oral versus intravenous ganciclovir for the prophylaxis of cytomegalovirus disease after allogeneic bone marrow transplantation.
BACKGROUND
Prophylactic low dose i.v. ganciclovir in patients at risk after allogeneic bone marrow transplantation (BMT) is highly effective in the prevention of cytomegalovirus (CMV) disease and infection.


OBJECTIVE
In this study, we sought to assess the tolerability of oral ganciclovir in patients after allogeneic BMT.


METHODS
CMV seropositive patients or those with CMV seropositive donors were randomised to be treated with i.v. ganciclovir 5 mg/kg three times weekly or oral ganciclovir 3 g daily from engraftment to day 84. The period of accrual was from May 1997 to October 1998. Patients were monitored for CMV infection by weekly serology. Thirty-one patients received oral ganciclovir and 27 patients received i.v. ganciclovir, the treatment groups being balanced for clinical characteristics and prognostic factors.


RESULTS
Renal dysfunction, transfusion requirements and significant nausea and vomiting were not different. There were no documented cases of CMV disease during the study period although three patients developed CMV polymerase chain reaction positivity at various times. One patient treated with i.v. ganciclovir developed non-fatal gastrointestinal CMV disease after the study period on day 108. Eight patients in the oral group failed to complete planned therapy, whereas two patients failed to complete the i.v. course.


CONCLUSIONS
We conclude that oral ganciclovir is a reasonable, well-tolerated alternative to i.v. ganciclovir for the prophylaxis of CMV disease after allogeneic BMT.
