CSF B – lymphocyte chemoattractant (CXCL13) in the early diagnosis of acute Lyme neuroborreliosis

摘要

Recent studies have suggested a diagnostic role of the B-lymphocyte attracting chemokine (CXCL13) in the cerebrospinal fluid (CSF) in Lyme neuroborreliosis (LNB). Our aim was to evaluate diagnostic accuracy of CSF CXCL13 in a cohort of 59 consecutive patients referred to hospital for suspected LNB. Thirty-seven patients were classified as definite LNB and used as the reference standard. Seven were classified as probable, and seven as possible LNB. Eight patients did not fulfil case definitions and were used as controls.
