Serum and cerebrospinal fluid proteins in tuberculous meningitis
Abstract:
Serum and CSF protein electrophoresis was performed on cellulose acetate in 8 controls and 30 cases of tuberculous meningitis before treatment and during a hospitalization period of 5 months. The analysis of the CSF electrophoretic pattern showed that abnormalities in the prealbumin, beta and gamma fractions may still exist as late as 5 months after initiation of treatment. An increase in alpha 2 and decrease in the albumin fractions in the serum also persisted. Treatment for 20 weeks improved the clinical condition of the patients and resulted in a significant improvement in the CSF prealbumin and alpha 1 fractions. These findings indicate that changes in these fractions may be considered a good prognostic aid.
Insights
Tuberculous meningitis disrupts cerebrospinal fluid (CSF) and serum protein electrophoresis patterns, with some abnormalities persisting for 5 months despite treatment. However, improvements in specific CSF fractions indicate potential as prognostic markers.
Area of Science:
- Neurology
- Infectious Diseases
- Clinical Chemistry
Background:
- Tuberculous meningitis (TBM) is a severe infection affecting the central nervous system.
- Protein electrophoresis is a diagnostic tool that analyzes protein composition in biological fluids.
- Understanding protein changes in TBM is crucial for diagnosis and prognosis.
Purpose of the Study:
- To investigate changes in serum and cerebrospinal fluid (CSF) protein electrophoresis during tuberculous meningitis treatment.
- To evaluate the potential of these protein changes as prognostic indicators for TBM.
Main Methods:
- Serum and CSF protein electrophoresis performed using cellulose acetate.
- Analysis included 8 controls and 30 TBM patients before and during a 5-month hospitalization.
- Clinical condition and electrophoretic patterns were monitored throughout the treatment period.
Main Results:
- Abnormalities in CSF prealbumin, beta, and gamma fractions persisted up to 5 months post-treatment initiation.
- Persistent serum changes included increased alpha 2 and decreased albumin fractions.
- Twenty weeks of treatment led to clinical improvement and significant enhancement of CSF prealbumin and alpha 1 fractions.
Conclusions:
- CSF and serum protein electrophoresis reveal persistent abnormalities in TBM patients during treatment.
- Improvements in specific CSF protein fractions (prealbumin, alpha 1) correlate with clinical recovery.
- Changes in these CSF fractions serve as valuable prognostic indicators for tuberculous meningitis.
