title: Evaluation of cerebrospinal fluid S100B protein concentration in patients with purulent, bacterial meningitis - own observations.
abstract: The aim of the study was evaluation of usefulness of cerebrospinal fluid (CSF) S100 B protein concentration assessment in adults with purulent, bacterial meningoencephalitis.
  
  
  METHODS
  The investigation was performed in 16 subjects hospitalized at the Department of Infectious Diseases of Medical University of Silesia in Bytom in 2008 - 2012 due to purulent, bacterial meningoencephalitis. All patients were divided into two groups according to the severity of their clinical condition: I group - very severe course of the disease, II group - moderate and mild course of the disease. In all individuals CSF S100 B protein concentration was evaluated during the first 24 hours ofhospitalization.
  
  
  RESULTS
  Mean CSF S100 B protein concentration in patients in very severe clinical condition (group I) was 1215.63 pg/mL compared to 419.56 pg/mL in subjects of group II with moderate and mild course of disease. The difference between CSF mean concentration of this protein was statistically significant (p<0.01). No correlations were assessed between CSF S100 B protein concentrations and other CSF inflammatory parameters. Control assays performed in 7 patients from group I revealed only slightly decrease of CSF S100 B protein level in fatal course of the disease. In survivals with recovery CSF concentration of this protein was evident decreased compared to initial level.
  
  
  CONCLUSIONS
  The obtained results indicate the usefulness of CSF S100 B protein concentration assessment in estimation of severity of the patient's clinical condition. The level of this protein concentration also seems to be helpful as prognostic marker in purulent, bacterial meningoencephalitis.
