Abstract

BACKGROUND: Recently, in vitro studies demonstrated faster immune reconstitution after allogeneic peripheral blood stem cell transplantation (PBSCT) compared to bone marrow transplantation (BMT). In consequence, it can be expected that better immune reconstitution against cytomegalovirus (CMV) will lead to a reduced CMV-related morbidity and mortality after allogeneic PBSCT.
METHODS
Forty seven patients who received allogeneic PBSCT were enrolled. CMV was routinely sought by at least weekly screening for CMV-related matrix protein pp65 antigenemia after engraftment (WBC >1,500/nL) was achieved. CMV antigenemia was treated with ganciclovir 5mg/kg twice daily i.v. as preemptive therapy for at least 10 days. After then, ganciclovir i.v. was switched to oral ganciclovir for maintenance therapy.
RESULTS
CMV antigenemia was detected 8 (17%) out of 47 patients and CMV disease developed in only 1 case (2.1%). The medianperiod of time until the detection of CMV antigenemia was 51.5 days (range, 35~230). In 7 out of 8 cases, CMV antigenemia disappeared with ganciclovir treatment in 7 days. One patient with CMV disease (CMV interstitial pneumonitis) showed persistent CMV antigenemia for 3 months and expired due to restrictive lung disease.
CONCLUSION
The incidence of CMV antigenemia and resistance to ganciclovir treatment was lower than the incidence of those reported in allogeneic BMT trials. These findings suggest that faster immune reconstitution against CMV after allogeneic PBSCT might have a stronger role in the prevention of emergence of CMV antigenemia and ganciclovir treatment than after allogeneic BMT.
