Development of Kawasaki syndrome in autoimmune neutropenia after treatment with granulocyte colony-stimulating factor.

The article presents a case study of an 8-month-old boy who had high fever and lymphadenopathy which was treated with antibiotics but later developed into autoimmune neturopenia that led to the development of Kawasaki syndrome after being treated with granulocyte colony-stimulating factor (G-CSF). He was diagnosed with neutropenia due to the presence of anti-neutrophil antibody that was used for his lymphadenopathy. Plasma exchange (PE) therapy decreased dilation of his left coronary artery.
