Kawasaki disease (KD) is a type of systemic vasculitis that primarily affects
children under the age of five years old. For sufferers of KD, intravenous
immunoglobulin (IVIG) has been found to successfully diminish the occurrence of
coronary artery lesions. Anemia is commonly found in KD patients, and we have
shown that in appropriately elevated hepcidin levels are related to decreased
hemoglobin levels in these patients. In this study, we investigated the time
period of anemia and iron metabolism during different stages of KD. A total of
100 patients with KD and 20 control subjects were enrolled in this study for red
blood cell and hemoglobin analysis. Furthermore, plasma, urine hepcidin, and
plasma IL-6 levels were evaluated using enzyme-linked immunosorbent assay in 20
KD patients and controls. Changes in hemoglobin, plasma iron levels, and total
iron binding capacity (TIBC) were also measured in patients with KD. Hemoglobin,
iron levels, and TIBC were lower (p < 0.001, p = 0.009, and p < 0.001,
respectively) while plasma IL-6 and hepcidin levels (both p < 0.001) were higher
in patients with KD than in the controls prior to IVIG administration. Moreover,
plasma hepcidin levels were positively and significantly correlated with urine
hepcidin levels (p < 0.001) prior to IVIG administration. After IVIG treatment,
plasma hepcidin and hemoglobin levels significantly decreased (both p < 0.001).
Of particular note was a subsequent gradual increase in hemoglobin levels during
the three weeks after IVIG treatment; nevertheless, the hemoglobin levels stayed
lower in KD patients than in the controls (p = 0.045). These findings provide a
longitudinal study of hemoglobin changes and among the first evidence that
hepcidin induces transient anemia and hypoferremia during KD's acute inflammatory
phase.
