Cerebrospinal fluid (CSF) polyamine levels, including putrescine and spermidine, are altered in pediatric neurosurgical conditions. Elevated polyamines correlate with specific brain tumors and myelomeningocele, suggesting diagnostic potential.
Area of Science:
- Biochemistry
- Pediatric Neurology
- Neurosurgery
Background:
- Polyamines are essential for cell growth and proliferation.
- Altered polyamine levels in cerebrospinal fluid (CSF) may indicate neurological disorders in children.
- Understanding these changes is crucial for diagnosing and monitoring pediatric neurosurgical conditions.
Purpose of the Study:
- To investigate polyamine concentrations (putrescine and spermidine) in the CSF of children with and without neurosurgical conditions.
- To determine the relationship between polyamine levels, age, and specific neurological disorders.
- To explore the potential utility of polyamines in monitoring disease progression.
Main Methods:
- CSF samples were collected from pediatric patients.
- Polyamine content (putrescine and spermidine) was measured using assays.
- Data were analyzed based on age and neurological diagnosis.
Main Results:
- Putrescine and spermidine concentrations decreased with age.
- Elevated putrescine and spermidine levels were observed in children with medulloblastomas, glioblastomas, and astrocytomas.
- Infants and older children with myelomeningocele, hydrocephalus, and encephalocele showed significantly increased spermidine concentrations.
Conclusions:
- Polyamine levels in CSF are indicative of rapid cell proliferation and disorders affecting myelination in children.
- Putrescine and spermidine concentrations may serve as biomarkers for monitoring tumor progression.
- The influence of childhood growth and hydrocephalus must be considered when interpreting polyamine levels in brain tumor patients.
Abstract:
Specimens of CSF from 76 children without neurologic disease and from 191 children with neurosurgical conditions were assayed for polyamine content. Putrescine and spermidine concentrations decreased with age. In children with intracranial tumors, polyamine concentrations in lumbar CSF were comparable with those in ventricular CSF. Putrescine level was significantly increased in children with medulloblastomas. Spermidine level was increased in children with medulloblastomas, glioblastomas, and astrocytomas. Concentrations of putrescine and spermidine were significantly increased in infants with myelomeningocele and hydrocephalus. Spermidine concentrations were significantly increased in older children with myelomeningocele, encephalocele, and hydrocephalus. Polyamines thus seem to be increased by rapid cell proliferation and by disorders affecting myelination. Since putrescine and spermidine concentrations may be of use in monitoring tumor progression, the effects of childhood growth and of hydrocephalus must be considered for children whose brain tumors are associated with hydrocephalus.
