[Clinical evaluation of effects of KRN8601 (rhG-CSF) on neutropenia].
Clinical effects of KRN8601 (recombinant human granulocyte colony-stimulating factor:rhG-CSF) were studied in 26 patients with chronic neutropenia including 4 Kostmann's disease, 1 Shwachman's syndrome, 1 Lonsdale's syndrome, 1 glycogen storage disease Ib-associated, 6 chronic benign, 5 chronic hypoplastic, 2 cyclic, 4 autoimmune and 2 miscellaneous neutropenia. The patients were given rhG-CSF intravenously at doses of 20-540 micrograms/m2 or subcutaneously at doses 20-400 micrograms/m2, over the periods of 2-32 weeks. Increases in neutrophil counts occurred after rhG-CSF administration in 23 of the 26 patients. Patients with Kostmann's disease, Shwachman's syndrome and chronic hypoplastic neutropenia responded poorly compared to patients with other types of neutropenia. There were no serious side effects which caused interruption of the study. These results indicated a beneficial effect of KRN8601 in various types of chronic neutropenia.
