Introduction
Hydrocephalus is a common disorder of the central nervous system (CNS) in the pediatric population. Surgical treatment options involve ventriculoperitoneal shunt (VPS) placement. VPS infection is the most common complication of surgically treated hydrocephalus in pediatric patients [1, 2], which may lead to neuronal damage. Myelin basic protein (MBP) has been proposed as a marker of neuronal injury in a variety of contexts, and MBP levels in the cerebrospinal fluid (CSF) may be used to assess the severity of neuronal damage [1, 3, 4]. Therefore, the aim of this study was to evaluate the CSF level of myelin basic protein (MBP) in a group of pediatric patients with VPS infection.

Material and methods
Thirty CSF samples were collected from pediatric patients with VPS infection. CSF levels of MBP were measured at three time points, marked by contamination detection, obtention of the first sterile CSF culture, and VPS shunt implantation. The collected data were compared with those of the control group composed of children with active congenital hydrocephalus and valid CSF values.

Results
The MBP level in the study group was higher than the corresponding control values in the second and third measurements. The highest MBP level was reached in the study group in the second and third measurements.

Conclusions
The lack of normalization of MBP level in the CSF of children with shunt infection could be connected with ongoing brain damage. It takes longer than the normalization of CSF protein level and pleocytosis. The delay is associated with a prolonged reaction of the immunological system.
