Comparative StudyInterleukin-8 in cerebrospinal fluid from patients with septic and aseptic meningitis.
Using a monoclonal antibody enzyme immunoassay, the concentration of interleukin-8 (IL-8) in cerebrospinal fluid (CSF) from 52 patients suspected of having meningitis was studied. The CSF IL-8 concentration was significantly higher in septic meningitis of known and unknown etiology than in aseptic meningitis and significantly higher in aseptic meningitis than in patients without meningitis. ⋯ The IL-8 values used to distinguish septic from aseptic meningitis, at a cut-off point of 3.00 micrograms/l, showed a sensitivity of 81%, a specificity of 92%, and a positive predictive value of 96%. The results suggest that determining IL-8 levels may be useful in the differential diagnosis of meningitis.
