title: The risk of persistent carriage of methicillin-resistant Staphylococcus aureus in hematopoietic stem cell transplantation.
abstract: The clinical course of hematopoietic stem cell transplantation (HSCT) recipients was retrospectively analyzed to determine whether carriage of methicillin-resistant Staphylococcus aureus (MRSA) is a risk factor for MRSA infection during the neutropenic period. We studied four patients in whom MRSA colonies developed before HSCT. Two patients were previously diagnosed as having MRSA infection and two were carriers of MRSA. We tried to eliminate MRSA before HSCT and succeeded in eradication in two patients. MRSA infection did not develop in one patient who received prophylactic administration of vancomycin (VCM), but MRSA-induced phlegmon developed during neutropenia in one patient who did not receive prophylaxis. Of the other two patients who had been persistently positive for MRSA, MRSA did not develop in one patient who received prophylaxis, but the another patient who did not receive prophylaxis died from MRSA-induced sepsis in the early post-transplant period. We therefore recommend that MRSA be eliminated by prophylactic administration of anti-MRSA drugs such as VCM before HSCT when patients have persistent MRSA.
