Hematopoietic progenitors in cyclic neutropenia: effect of granulocyte colony-stimulating factor in vivo.
The number and growth factor requirements of committed progenitor cells (colony-forming units-granulocyte/macrophage and burst-forming units-erythroid) in three patients with cyclic neutropenia (two congenital, one acquired) were studied before and during therapy with recombinant human granulocyte colony-stimulating factor (G-CSF; 3 to 10 micrograms/kg/d). When the patients with congenital dise...
متن کاملIn vitro and in vivo hematopoietic effect of mutant human granulocyte colony-stimulating factor.
About 100 derivatives of human recombinant granulocyte colony-stimulating factor (rhG-CSF) were created by various gene-mutagenic techniques, and KW-2228, in which amino acids were replaced at five positions of N-terminal region of intact rhG-CSF, was picked up and evaluated for its biologic and physicochemical properties in comparison with intact rhG-CSF. KW-2228 showed two to four times highe...
متن کاملThe Effect of Granulocyte Colony Stimulating Factor Administration on Preterm Infant with Neutropenia and Clinical Sepsis: A Randomized Clinical Trial
Abstract Background This study was conducted to evaluate the clinical effect of Granulocyte Colony Stimulating Factor (GCSF) on prognosis of neonatal sepsis. Materials and Methods Present study is a double- blinded randomized clinical trial, conducted on 46 preterm infants with neutropenia (Absolute Neutrophil Count (ANC) ≤ 5000 / μL) and clinical sepsis. Infants were randomly allocated ...
متن کاملAbnormal responses of myeloid progenitor cells to granulocyte-macrophage colony-stimulating factor in human cyclic neutropenia.
Granulocyte-macrophage progenitors (CFU-GM) from four patients with childhood onset cyclic neutropenia demonstrated abnormal in vitro proliferative responses to purified, recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) when examined in detailed dose-response studies. Marrow aspirate specimens were obtained for these studies from cyclic neutropenia patients (both du...
متن کاملDifferential effects of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor in children with severe congenital neutropenia.
Severe congenital neutropenia (SCN) is a disorder of myelopoiesis characterized by severe neutropenia secondary to a maturational arrest at the level of promyelocytes. We treated five patients with SCN with recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) for 42 days and subsequently, between 1 and 3 months later, with rhG-CSF for 142 days. The objective was to eval...
