[Determination of serum granulocyte colony-stimulating factor level in patients with chronic idiopathic neutropenia and its significance].
To investigate the serum granulocyte colony-stimulating factor (G-CSF) level in patients with chronic idiopathic neutropenia (CIN) and analyze its clinical significance. By the use of G-CSF-specific enzyme-linked immunosorbent assay (ELISA), the serum levels of G-CSF were determined in 40 cases with chronic CIN, 40 cases with systemic lupus erythematosus (SLE) complicated neutropenia and 40 healthy volunteer (normal control). Results showed that serum G-CSF was positive in 11 normal controls and in 10 cases with SLE, and the G-CSF levels were (27.34 +/- 8.00) ng/L and (26.76 +/- 7.26) ng/L, respectively. Serum G-CSF in 27 cases with CIN was positive, the level was (134.04 +/- 89.29) ng/L, which was higher than that in the normal controls and the cases with SLE (P < 0.01). It was concluded that an obstacle to utilization of G-CSF could be existed in the patients with CIN.
