title: Cerebrospinal fluid profile in patients with acute Kawasaki disease.
abstract: BACKGROUND
  Kawasaki disease (KD) is an acute vasculitis of infancy and early childhood for which there is currently no diagnostic test. The clinical presentation of KD may initially resemble other infectious diseases, including bacterial or viral meningitis. For this reason lumbar puncture (LP) is sometimes performed during the evaluation of these patients. To understand the range of cerebrospinal fluid (CSF) changes that may be associated with acute KD, a retrospective review of unselected KD patients from three pediatric centers was performed.
  
  
  METHODS
  Retrospective chart review was performed on KD patients evaluated during the first 10 days of illness who had an LP performed before the administration of intravenous gamma-globulin.
  
  
  RESULTS
  During the 6.5-year study period, 46 KD patients underwent LP as part of their clinical evaluation. Of these patients 18 (39.1%) had CSF pleocytosis, 1 (2.2%) had a CSF glucose <45 mg/dl and 8 (17.4%) had an elevated CSF protein. Of the patients with CSF pleocytosis, the median white blood cell count was 22.5 cells (range, 7 to 320 cells), with a median of 6.0% neutrophils (range, 0 to 79%) and 91.5% mononuclear cells (range, 11 to 100%).
  
  
  CONCLUSIONS
  In the present series approximately one-third of KD patients who underwent an LP had CSF pleocytosis with a mononuclear cell predominance. No patient had significant hypoglycorrhachia, and elevation of the CSF protein was uncommon. CSF abnormalities were similar between US and Japanese KD patients. The basis for the CSF pleocytosis in acute KD patients remains unknown.
