Levels of serum granulocyte colony-stimulating factor in patients with cerebrovascular diseases.
The role of leukocytes in the pathogenesis of cerebrovascular disease, in particular, cerebral ischemic disease has recently become a focus of research. Several studies have reported that a positive correlation between increased functional activities of neutrophils and the risk of cerebral ischemic disease. Granulocyte colony-stimulating factor (G-CSF) is known to be not only a granulocyte proliferating factor but also a potent activator of mature neutrophils. In this study, we measured the serum G-CSF levels in 143 patients with cerebrovascular diseases and in 100 patients with other diseases, using our established enzyme-linked immunosorbent assay (ELISA) for G-CSF The minimal detection level was 20 pg/ml G-CSF. In patients with cerebral infarction, G-CSF could be detected in 18.3% and in patients with cerebral hemorrhage, it could be detected in 9.8% of analyzed samples. On the other hand, 6% of the patients with other diseases had measurable levels of G-CSF. The differences among these three groups were statistically significant according to the chi 2 test (p < 0.01). Our findings that there was a significantly high frequency of elevated levels of G-CSF among patients with cerebrovascular diseases, may indicate that the action of G-CSF as a potent activator of neutrophils plays some role in the occurrence of cerebrovascular disease, in particular, cerebral infarction.
