title: Evaluation of recombinant human granulocyte colony-stimulating factor (rhG-CSF) therapy in granulopoetic patients complicated with sepsis.
abstract: A study was carried out to investigate the efficacy of therapy with recombinant human granulocyte colony-stimulating factor (rhG-CSF) in 24 patients with granulocytopenia and sepsis who had failed to respond to antibiotics. The mean leukocyte count at the start of the study was 911 +/- 334/microliter. Patients were injected subcutaneously with 75 micrograms rhG-CSF once daily for a mean of 5.2 days. The plasma G-CSF concentration was measured by ELISA. The leukocyte count increased approximately 9-fold after 1 week in 19 patients and the percentage of granulocytes rose from 46.2% to 78.9%. These 19 patients survived, while the 5 patients with no leukocyte response to rhG-CSF died. High plasma G-CSF levels were found in patients with granulocytopenia. Plasma G-CSF levels decreased as levels of granulocyte increased in survivors. A high plasma G-CSF concentration persisted in the 5 non-responding patients resulting in a fatal outcome. This study suggests that rhG-CSF both increased the leukocyte count and was a useful therapeutic manoeuvre for sepsis.
