Effects of Recombinant Human Granulocyte Colony-Stimulating Factor on Neutropenia in Patients with Congenital Agranulocytosis

Abstract
Congenital agranulocytosis is a disorder characterized by severe neutropenia and a profound deficiency of identifiable neutrophil progenitors in bone marrow. In an attempt to stimulate neutrophil production and thereby reduce the morbidity and mortality associated with this disease, we administered recombinant human granulocyte colony-stimulating factor (rhG-CSF) in doses of 3 to 60 μg per kilogram of body weight per day to five patients with congenital agranulocytosis.
