The CSF myelin basic protein in pediatric hydrocephalus.

Concentrations of myelin basic protein (MBP) in ventricular and lumbar cerebrospinal fluid (CSF) of 20 pediatric hydrocephalic patients were reviewed. Raised values were found to be particularly significant in children aged more than 1 year. Control measurements after shunt placement showed an important drop in the MBP concentration, which could therefore be considered a marker for correct functioning of the shunt. The dosage of MBP could play a role in assessing the activity of an hydrocephalic process. Preliminary data gained from monitoring of MBP in the lumbar CSF in posthemorrhagic neonatal hydrocephalus could yield further criteria for indication of a shunt operation.
