Remission of autoimmune neutropenia after development of Kawasaki disease.
We report the second case of the association of Kawasaki disease (KD) and autoimmune neutropenia (AIN). A 21-month-old female diagnosed as having AIN of infancy developed a complete KD when severe neutropenia continued. The patient suffered from no coronary artery lesions, and well responded to a single high-dose gamma-globulin therapy. The cytokine profile of the neutropenic infant was representative of the typical KD. Neutrophil counts notably increased during the convalescent phase of KD, and were then normalized forthwith. The prompt resolutions of KD and AIN paralleled the increase of circulating transforming growth factor (TGF)-β1 levels. The clinical course of the patient was contrasted to that of the first reported case of a patient who developed severe and refractory KD after the high dose granulocyte-colony stimulating factor (G-CSF) therapy.
