[Cerebrospinal fluid proteins in the course of subacute sclerosing panencephalitis in children]
Insights
Subacute sclerosing panencephalitis (SSPE) in children often shows elevated cerebrospinal fluid protein levels. Key findings include decreased albumin and increased globulins and IgG, regardless of disease stage.
Area of Science:
- Neurology
- Biochemistry
- Immunology
Context:
- Subacute sclerosing panencephalitis (SSPE) is a rare, progressive neurological disorder affecting children.
- Cerebrospinal fluid (CSF) analysis is crucial for diagnosing and monitoring neurological conditions.
- Understanding protein alterations in CSF can provide insights into SSPE pathogenesis.
Purpose:
- To investigate changes in cerebrospinal fluid (CSF) protein profiles in children diagnosed with subacute sclerosing panencephalitis (SSPE).
- To quantify total protein, albumin, globulins (tau + gamma), and IgG concentrations in the CSF of SSPE patients.
- To correlate these biochemical findings with the clinical stage and duration of SSPE.
Summary:
- CSF samples from 31 children with SSPE were analyzed for protein content and electrophoretic fractions 1-28 months post-symptom onset.
- Elevated total protein was observed in nearly half of the samples.
- A significant decrease in albumin proportion and a marked increase in globulins (tau + gamma) and IgG immunoglobulins were prevalent in SSPE patients compared to controls.
Impact:
- The study highlights characteristic CSF protein abnormalities in SSPE, aiding in diagnosis and understanding disease mechanisms.
- Findings suggest a strong intrathecal immune response involving IgG production in SSPE.
- No correlation was found between CSF protein changes and SSPE disease phase or duration, indicating these alterations are consistent throughout the disease course.
Abstract:
In cerebrospinal fluid samples obtained from lumbar tap from 31 children with subacute sclerosing panencephalitis the concentration of total protein was determined and electrophoretic separation of protein fractions on paper was carried out from 1 to 28 months after the onset of first clinical symptoms. Moreover, in 22 children the concentration of IgG was determined by electroimmunodiffusion. The reference group included 22 children without organic diseases of the central nervous system. In nearly half the samples of the cerebrospinal fluid obtained from these children a rise was observed in total protein level, and in most samples a significant fall of albumin proportion and an evident rise of this relative proportion of globulins (tau + gamma) and IgG immunoglobulins was observed. No correlation was demonstrated between changes in cerebrospinal proteins and the phase of the disease and its duration.
