CSF protein values in infants and children.

O E Illi, G Kaiser, R M Weber

    Summary

    Cerebrospinal fluid (CSF) protein levels in children show a unique pattern, decreasing in early childhood and rising to adult levels by age 8. Albumin levels significantly influence these changes, supporting the Bradford method for routine analysis.

    Area of Science:

    • Pediatric Neurology
    • Clinical Chemistry

    Background:

    • Cerebrospinal fluid (CSF) analysis is crucial for diagnosing neurological conditions in children.
    • Understanding normal CSF protein ranges is essential for accurate diagnosis.

    Purpose of the Study:

    • To determine normal ranges for total protein, albumin, and gamma-globulin in pediatric CSF.
    • To characterize the developmental changes in CSF protein levels during childhood.

    Main Methods:

    • Quantitative analysis of total protein, albumin, and gamma-globulin in CSF samples from 139 children.
    • Utilized the Bradford method for routine CSF work-up.

    Main Results:

    • Established a wide normal range (0.1-0.65 g/l) for protein in newborns and infants.
    • Observed a decline in protein levels at 3-4 years, reaching adult levels by 6-8 years.
    • Identified albumin as the primary factor influencing these age-related protein variations.

    Conclusions:

    • CSF protein levels exhibit significant age-dependent variations in children.
    • The findings support the reliability and utility of the Bradford method for pediatric CSF protein analysis.
    • Contradicts previous claims of constantly falling protein levels throughout childhood.
