Peripheral blood monocyte/macrophages and serum tumor necrosis factor in Kawasaki disease.
We analyzed the populations of peripheral blood monocyte/macrophages in 27 patients using a fluorescence-activated cell sorter, and investigated the possibility, in another 30 patients, that tumor necrosis factor (TNF) might be detectable in serum during the acute phase of Kawasaki disease (KD). Percentages of peripheral blood monocyte/macrophages among mononuclear cells and serum TNF levels were both seen to increase during the acute phase of the illness in patients with KD. The percentage of TNF positive cases in KD patients with coronary involvement was higher than that of patients without coronary involvement. These results suggest the possibility that immunological activation, accompanied by the secretion of TNF from monocyte/macrophages, is an important predisposing condition for the exacerbation of vascular damage in KD.
