Serum granulocyte colony‐stimulating factor in patients with repeated infections

Abstract

We have already reported significant elevation of serum granulocyte colony-stimulating factor (G-CSF) in the acute phase of infection. In this study, we compared the responses to infection between patients with frequently repeated infection (repeaters) and others (non-repeaters). We examined the clinical data and serum G-CSF levels in 48 patients with acute infections. Serum G-CSF levels were significantly lower in repeaters than in non-repeaters (197.7 +/- 370.0 vs. 1014.1 +/- 924.4 pg/ml. P less than 0.001). There were no significant differences in age, serum total protein, or cholinesterase between the groups, but serum albumin was significantly lower in repeaters than in non-repeaters (2.87 +/- 0.5 vs. 3.31 +/- 0.4 g/dl. P less than 0.005). It is suggested that administration of recombinant G-CSF may be useful for patients with repeated infections.
