Neutrophil chemotactic activity in the plasma of patients with Kawasaki disease. The average neutrophil chemotactic activity in the acute phase (93 ± 71 neutrophils per 10 high power fields (HPF), n = 15) was increased compared with healthy controls (66 ± 12 neutrophils per 10 HPF, n = 10). This activity was further increased (220 ± 69 neutrophils per 10 HPF, n = 15) after intravenous immunoglobulin therapy (P < 0·05).
