Response to Granulocyte Colony-Stimulating Factor in an Autoimmune Neutropenic Adult

Response to Granulocyte Colony-Stimulating Factor in an Autoimmune Neutropenic Adult Clinical value of granulocyte colony-stimulating factor (G-CSF) for autoimmune neutropenia (AIN) has not been well established. We experienced an adult case of AIN which showed an excellent response to G-CSF. A 75-year-old female was admitted with high-grade fever. Her neutrophil count was remarkably low (neutrophil 0.09 × 10<sup>9</sup>/l). Antigranulocyte autoantibody was demonstrated in her serum by an immunofluorescence method and she was diagnosed as AIN. Administration of G-CSF (filgrastim 5 μg/kg) gave a rapid increase of neutrophils (from 0.11 × 10<sup>9</sup>/l to 2.10 × 10<sup>9</sup>/l on the second day), which has enabled us to preserve the use of G-CSF for emergency, that is, for overt serious infection. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Haematologica Karger

Abstract

Clinical value of granulocyte colony-stimulating factor (G-CSF) for autoimmune neutropenia (AIN) has not been well established. We experienced an adult case of AIN which showed an excellent response to G-CSF. A 75-year-old female was admitted with high-grade fever. Her neutrophil count was remarkably low (neutrophil 0.09 × 10<sup>9</sup>/l). Antigranulocyte autoantibody was demonstrated in her serum by an immunofluorescence method and she was diagnosed as AIN. Administration of G-CSF (filgrastim 5 μg/kg) gave a rapid increase of neutrophils (from 0.11 × 10<sup>9</sup>/l to 2.10 × 10<sup>9</sup>/l on the second day), which has enabled us to preserve the use of G-CSF for emergency, that is, for overt serious infection.
