Background
Kawasaki disease (KD) is an acute form of febrile vasculitis that occurs in early childhood. The multi-systemic vasculitis common in KD patients may influence blood perfusion in the brain, and thus caregivers of KD children may feel stress with regard to caring for them. Intravenous immunoglobulin (IVIG) infusion is the standard treatment for acute KD, and the most serious complication of KD is coronary artery aneurysms (CAL). This study aimed to investigate the relationships between KD heterogeneity and the risk of patients’ cognitive impairment or caregivers’ parenting stress.
Methods
This cross-sectional study consisted of 176 patients with KD (mean age: 5.5 years, 60.8% male) and 85 healthy children (mean age: 6.4 years, 54.1% male). Based on the children’s age, each KD patient and control subject was administered an assessment using the Mullen Scales of Early Learning or the Wechsler Intelligence Scale, and parenting function of their caregivers was assessed using the Parenting Stress Index-Short Form (PSI).
Results
We observed no significant differences in any developmental index, cognitive function, or parenting stress between KD patients and controls. Among the KD children, IVIG administration nor CAL was associated with children’s cognitive scores. However, the caregivers of patients who had CAL suffered from greater PSI total scores than those of patients without CAL (p = 0.019). Furthermore, the caregivers who had education levels of a master’s degree or above showed less parenting stress than those who had an education level of college (p = 0.010) or lower (p = 0.021).
Conclusion
No significant differences in developmental index, cognitive function or parenting stress between KD patients and controls. In KD patients, neither IVIG response nor CAL appear to have a relationship with development milestones or cognitive function. However, caregivers’ education is associated to parenting stress, and caregivers of KD patients who developed CAL may feel stress about the unpredictable sequela caused by CAL for their children. Such caregivers may require support to fulfill their parenting roles.
