To evaluate the intracranial inflammatory response in patients with acute-stage KD, we measured the levels of cytokines (interleukin [IL]-6 and tumor necrosis factor [TNF]-α) and pentraxin-3 (PTX3) in the cerebrospinal fluid of patients with KD (<i>n</i> = 7) and compared the levels to those of the age- and sex-matched febrile control patients (bacterial meningitis [<i>n</i> = 5], enteroviral meningitis [<i>n</i> = 10], nonspecific viral illness without central nervous system involvement [<i>n</i> = 10]).
Plasma concentrations of MCP-1, sCD14, IL-6, and IL-10 were significantly higher in patients with community-acquired pneumonia (CAP; <i>n</i> = 10) and infective endocarditis (IE; <i>n</i> = 11) compared to those with bacterial meningitis (BM; <i>n</i> = 18).
No correlation was found between the cerebrospinal fluid VEGF and PDGF levels and IL-6 level in the IAE group, whereas a correlation was found in the BM group.
