Increased creatine kinase brain isoenzyme concentration in cerebrospinal fluid with meningitis.
CPK-BB (CK-BB) isoenzyme is an intracellular enzyme released in various neurologic conditions, including central nervous system (CNS) infections. Activity of CK-BB in cerebrospinal fluid (CSF) was determined in 80 children by electrophoresis and densitometry. The possible correlation between CNS infection and CK concentrations was assessed. Significantly elevated concentrations of CK activity (P < 0.01) in the CSF were found in children with bacterial meningitis as compared with children with either aseptic meningitis or normal CSF findings. The data suggest the possibility of utilizing CSF CK activity to differentiate between bacterial and viral meningitis in situations where a routine CSF examination is inconclusive.
