PURPOSE
We performed this study to evaluate the changes of total leukocytes and leukocyte types in CSF and peripheral blood (PB) in the early course of aseptic meningitis. METHODS: One hundred and eighty-nine children with aseptic meningitis, who were admitted to the Pediatric Department of Dong-A University Hospital during the period from June 1996 to October 1997 were included. Patients were divided into 4 groups by 12-hour intervals according to the time between the onset of illness and initial diagnostic lumbar puncture. We analyzed clinical pictures, total leukocytes and leukocyte types in CSF and peripheral blood (PB) in each group. RESULTS: 1) There was no significant difference in average total leukocyte counts in CSF between each group, and all groups were considered to be acute stage of illness. 2) The PMNL proportion of CSF leukocytes was 57.0+/-31.6% in group I, 44.1+/-32.3% in group II, 39.4+/-33.1% in group III and 26.9+/-27.9% in group IV. The PMNL percentage was significantly higher in group I than group III and IV and the proportion of patients with a predominance of PMNL was higher in group I than group III and IV (p<0.05) 3) The proportion of neutrophils in PB was highest in group I (76.5+/-15.7%) and significantly higher in group I and II than group III and IV (p<0.05). 4) Significant correlations were found between the proportion of PMNL in CSF and PB of patients (r=0.62, p<0.001) CONCLUSION: The change from a predominance of PMNL to a predominance of mononucler leukocytes was occurred 12-24 hours after onset, and there was a strong correlation between the proportion of neutrophils in CSF and PB. |
