Abstract

PURPOSE
Cytokines play important roles on the expression of various neuronal inflammatory disease and insults. The purpose of this study was to evaluate the levels of interleukine (IL)-6, IL-8, IL-10 in cerebrospinal fluid (CSF) in children with aseptic meningitis and compare them with those of the patients having other acute neurological symptoms.
METHODS
We retrospectively reviewed the medical records of the children who admitted in the pediatric department of Hanyang University Guri Hospital for acute neurological symptoms and had CSF examinations from September 2012 to July 2013. We classified them into six groups as acute encephalopathy, epilepsy, febrile convulsion, headache, infantile fever, and meningitis. We analyzed the clinical and laboratory data from them.
RESULTS
A total of 87 CSFs of the patients were available. The levels of CSF IL-6, IL-8, and IL-10 were significantly increased in the group with aseptic meningitis group as compared to the other groups (P<0.05). CSF IL-6 (r=0.576, P=0.000), IL-8 (r=0.329, P=0.003), and IL-10 (r=0.523, P=0.000) were all significantly correlated with CSF White bood cell (WBC) count. Among the patients with aseptic meningitis, CSF enterovirus positive patients (CSF entero+) showed significantly increased IL-6, IL-8, IL-10 levels than CSF enterovirus negative patients (CSF entero-) (P<0.05). In addition, the CSF entero+ and the increase of IL-10 were significantly correlated (x2=6.827, P=0.033).
CONCLUSION
In patients with aseptic meningitis, the CSF IL-6, IL-8 and IL-10 were more expressed than in other neurological disease group. Among them, the enteroviral meningitis may be more related with IL-6, IL-8 and IL-10 expression than in other causes of aseptic meningitis.
