Interferon-gamma in cerebrospinal fluid of children with aseptic meningitis.
BACKGROUND
Certain cytokines may contribute to the sequence of events that lead to meningeal inflammation in bacterial meningitis. However, their role in viral meningitis is not so less well defined. We determined the cytokines levels in the cerebrospinal fluid (CSF) of children with aseptic meningitis and discussed their relationship with clinical and laboratory findings.


METHODS
We determined the concentrations of interleukin-1 beta (IL-1 beta), interferon-gamma (IFN-gamma) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in the CSF of 62 patients with aseptic meningitis including 17 patients with culture-proved enteroviral meningitis, and from 19 control acute febrile patients without meningitis.


RESULTS
The GM-CSF in the cerebrospinal fluid was detected from one of the 62 patients with aseptic meningitis and none of the 19 controls. Fourteen (23%) of the 62 patients with aseptic meningitis and 2 (10.5%) of 19 controls had detectable IL-1 beta. There was no significant difference in IL-1 beta levels between patients with aseptic meningitis (4.4 +/- 11.4 pg/ml) and control group (2.4 +/- 7.7 pg/ml). The CSF IFN-gamma level was detectable in 40 (65%) of 62 patients and 6 (31.6%) of 19 controls. The mean CSF IFN-gamma concentration was significantly higher in patients with aseptic meningitis when compared with that in control group (37.9 +/- 48.8 pg/ml vs 17.5 +/- 29.7 pg/ml; p = 0.007).


CONCLUSIONS
IFN-gamma was detectable in the CSF in 65% of patients with aseptic meningitis and the role of interferon-gamma remains to be determined.
