To investigate the regulation and clinical kinetics of Fc gamma receptor expression on circulating phagocytes in children with Kawasaki disease.
Evaluated cell-surface expression of FcγRI, FcγRII, and FcγRIII on circulating neutrophils and monocytes using flow cytometric analysis.
Studied 50 participants across four cohorts: Kawasaki disease (N=20), bacterial infection (N=10), viral infection (N=10), and healthy controls (N=10).
Performed kinetic analyses across the acute, subacute, and convalescent phases of Kawasaki disease.
Neutrophil FcγRI expression was significantly higher in Kawasaki disease than in bacterial infections, viral infections, and healthy controls, whereas monocyte FcγRI levels showed no significant differences.
Kawasaki disease patients exhibited significantly lower neutrophil FcγRIII expression compared to viral infection and healthy controls, while monocyte FcγRIII expression was significantly elevated.
Kinetic monitoring revealed that neutrophil FcγRI and FcγRII declined during subacute and convalescent phases, whereas neutrophil FcγRIII increased and monocyte FcγRIII decreased back toward baseline levels.
