title: Prolonged vancomycin-associated neutropenia in a chronic hemodialysis patient.
abstract: A chronic hemodialysis patient developed severe marrow granulocytic hypoplasia and peripheral blood neutropenia related to vancomycin therapy for an infected arteriovenous fistula. Neutropenia was prolonged and associated with sustained serum levels of vancomycin that persisted for more than 4 weeks following the last dose of vancomycin. No vancomycin-dependent leukoagglutinins were demonstrable in the patient's serum. Although a direct toxic effect on marrow granulocyte production seems likely, a vancomycin-dependent immune suppression of granulopoiesis cannot be ruled out.
