Insights
Children with Kawasaki disease (KD) aged under 1 or over 8, males, and those with delayed IVIG treatment face higher risks of coronary artery lesions (CAL). Early IVIG treatment is protective against CAL development in KD patients.
Area of Science:
- Pediatric Cardiology
- Immunology
- Rheumatology
Context:
- Kawasaki disease (KD) is a leading cause of acquired heart disease in children.
- Coronary artery lesions (CAL) are the most serious complication of KD.
- Identifying risk factors for CAL is crucial for timely intervention and management.
Purpose:
- To investigate the risk factors associated with the development of coronary artery lesions (CAL) in children diagnosed with Kawasaki disease (KD).
Summary:
- Retrospective analysis of 527 children with KD identified several independent risk factors for CAL.
- These include younger age (<1 year), older age (>8 years), male sex, incomplete KD, delayed intravenous immunoglobulin (IVIG) treatment (>10 days), non-response to IVIG, and prolonged fever (>10 days).
- Early IVIG treatment (before 5 days) demonstrated a protective effect against CAL.
Impact:
- Findings highlight critical demographic and clinical factors influencing CAL development in KD.
- Informs clinical practice for risk stratification and targeted management strategies in pediatric KD patients.
- Contributes to understanding KD pathogenesis and improving long-term cardiovascular outcomes in affected children.
Objective:
To study risk factors for the development of coronary artery lesions (CAL) in children with Kawasaki disease (KD).
Methods:
The clinical data of 527 children with KD between January 2006 and January 2009 were retrospectively reviewed. A total of 15 potential factors associated with occurrence of CAL were evaluated by univariate analysis and multivariate logistic regression analysis.
Results:
The univariate analysis showed that age, gender, KD type, starting time of intravenous immunoglobulin (IVIG) treatment, response to IVIG treatment, additional treatment with corticosteroids, duration of fever and serum C-reactive protein level were significantly different between patients with and without CAL (P<0.05). Multivariate logistic regression analysis showed that an age of less than 1 year (OR=2.076, P<0.05) or greater than 8 years (OR=1.890, P<0.05), male sex (OR=1.972, P<0.05), incomplete KD (OR=1.426, P<0.05), delayed starting time of IVIG treatment (10 days after onset) (OR=3.251, P<0.05), no response to IVIG (OR=2.301, P<0.05) and fever duration of more than 10 days (OR=1.694, P<0.05) were independent risk factors for the development of CAL, whereas early starting time of IVIG treatment (before 5 days after onset) was a protective factor (OR=0.248, P<0.05).
Conclusions:
The occurrence of CAL is associated with many factors in children with KD. Age of less than 1 year or greater than 8 years, male sex, incomplete KD, delayed IVIG treatment after onset, no response to IVIG treatment and prolonged fever duration have been identified as risk factors for the development of CAL.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
