Cerebrospinal fluid chemokine CXCL13 in the diagnosis of neuroborreliosis in children.
BACKGROUND: The diagnosis of Lyme neuroborreliosis (LNB) requires laboratory confirmation because neurological symptoms indicative of LNB are not specific. Recent studies have suggested that a chemokine, CXCL13, could have an important role in the diagnosis of LNB. The aim of this study was to assess CXCL13 levels in the cerebrospinal fluid (CSF) of children with LNB.
METHODS: CSF samples were available for 57 children with symptoms indicative of LNB. Based on the presence of anti-flagella antibodies and pleocytosis in CSF, patients were divided into 3 different groups: confirmed LNB (n = 24), possible LNB (n = 16), and non-LNB (n = 17). CXCL13 levels were determined with a commercial kit (Quantikine).
RESULTS: All 24 patients with confirmed LNB had elevated CXCL13 levels in CSF. Elevated CXCL13 was also observed in the majority of patients without anti-flagella antibodies in the CSF (possible LNB). Of the 17 non-LNB and 50 control samples, 1 was positive.
CONCLUSIONS: In LNB, the production of CXCL13 in CSF seems to precede antibody production. Assessment of CSF CXCL13 may improve the diagnostics for children with possible LNB.
