Raised serum interleukin 15 levels in Kawasaki disease

Objective: To examine the serum levels of IL15 in KD and to evaluate the role of IL15 in estimating the severity of inflammation in KD. Results and conclusion: There was a significant increase in the mean (SD) serum levels of IL15 measured in the acute stage of KD (11.5 (5.8) pg/ml) compared with those in the subacute stage (1.3 (0.9) pg/ml) (p<0.01) and normal controls (0.9 (1.0) pg/ml) (p<0.01). The increase in IL15 correlated with the increase in TNFα (rs=0.66, p
