Initial Characteristics of Kawasaki Disease With Cerebrospinal Fluid Pleocytosis in Febrile Infants

초록

To distinguish between febrile infants with cerebrospinal fluid pleocytosis who are finally diagnosed with Kawasaki disease and those with enterovirus meningitis poses a diagnostic challenge. We compared clinical and laboratory features at admission between two groups of infants, aged 30-90 days, to identify markers of Kawasaki disease that initially presented as cerebrospinal fluid pleocytosis. During a 2-year period, 100 patients exhibiting cerebrospinal fluid pleocytosis were studied, including six (6.0%) with Kawasaki disease and 30(30.0%) with enterovirus meningitis. A longer duration of fever before admission (P < 0.01), higher absolute neutrophil count (P < 0.01), increased C-reactive protein level (P < 0.01), pyuria (P = 0.02), and less prominent cerebrospinal fluid pleocytosis (P = 0.01) were identified as initial features of infants finally diagnosed with Kawasaki disease. No significant differences were evident in white blood cell count; platelet count; levels of hemoglobin, alanine aminotransaminase, aspartate aminotransferase, albumin, and sodium; cerebrospinal fluid chemistry; or presence of a rash. Our observations may offer early indicators of Kawasaki disease for timely diagnoses in febrile infants with cerebrospinal fluid pleocytosis. (c) 2012 Elsevier Inc. All rights reserved.
