title: Prospective study on the chemokine CXCL13 in neuroborreliosis and other aseptic neuroinfections.
abstract: The study evaluates the clinical significance of CXCL13 (leukocyte chemoattractant synthesized in CSF ) in Lyme neuroborreliosis (LNB) and other aseptic CNS infections. 244 patients with symptoms of neuroinfection and/or LNB were divided into groups: A - patients with LNB-positive antibodies in serum and CSF (96) or CSF only (14); B - patients with aseptic non-borrelial neuroinfections (82); C - negative controls (52). Group A was divided into A1-A4 according to pleocytosis in CSF and AIIgG positivity. The highest CSF CXCL13 concentrations (max. 81,287.60pg/ml; median 1766.90pg/ml) were in A1 (positive AI, pleocytosis) and A3 (negative AIIgG, pleocytosis; max. 7201,60pg/ml, median 56.22pg/ml). A2 (positive AI without pleocytosis) and A4 (negative AI without pleocytosis) had low CXCL13 levels - A2 max. 650.50pg/ml (median<7.80pg/ml); A4 max. 118.56pg/ml (median<7.8pg/ml). In B the median was 28.10pg/ml (max. 595.87pg/ml). In C the CXCL13 concentrations were the lowest (max. 83.83pg/ml; median<7.80pg/ml). The lowest cut-off was 29pg/ml (sensitivity 90.0%, specificity 72.2%), the highest one 400pg/ml (sensitivity 59.6%, specificity 94.0%). The group differences of serum CXCL13 were insignificant. The highest concentrations were at the beginning of the disease. In LNB CXCL13 correlates better with the CSF pleocytosis than AI positivity.
