HAMP and anemia (phenotype): Anemia is a common finding in KD, and in our previous study, we provided a mechanism to explain anemia in KD patients: it is related to a markedly increased hepcidin expression.[15] Moreover, the current study also introduces the novel observation that the lower decrease in hepcidin level after high-dose aspirin treatment was associated with a significantly lower hemoglobin level after IVIG treatment in the KD patients.
