Objective To assess the distinguishing features of aseptic meningitis (AM) in patients with Kawasaki disease (KD) compared with bacterial meningitis (BM) patients. Methods Thirty-eight patients with KD and 126 patients with BM were retrospectively investigated. The following clinical manifestations and laboratory parameters were compared between the two groups: duration of fever before lumbar puncture, conjunctival injection, oral cavity changes, rash, cervical lymphadenopathy and extremity changes, vomiting, front fontanel bulging, neck stiffness, leukocyte number, hemoglobin level, platelet number, C-reactive protein level, cerebrospinal fluid (CSF) content, liver enzyme level, and urinalysis. Results Vomiting and neck stiffness were more prevalent in patients with BM. KD patients with AM showed elevated blood leukocyte numbers and C-reactive protein levels in the early febrile stage. CSF glucose was significantly lower in patients with BM compared with KD patients with AM. Receiver operating characteristic curve analysis showed that the optimal cutoff value of CSF glucose for discrimination of BM and AM/KD was 2.945 mmol/L, with a sensitivity of 84.2% and a specificity of 71.4%. Conclusions Detailed investigations of clinical manifestation and laboratory parameters are necessary to distinguish AM and BM in patients with KD. Decreased CSF glucose is a potential indicator of BM.
