Insights
Kawasaki disease, a childhood vasculitis, often presents with fever and rash. Male sex, urticarial rash, and elevated C-reactive protein are key risk factors for developing coronary artery aneurysms in affected children.
Area of Science:
- Pediatric Rheumatology
- Pediatric Cardiology
- Infectious Diseases
Context:
- Kawasaki disease is a leading cause of acquired heart disease in children.
- Understanding clinical manifestations and cardiac complications is crucial.
- Identifying risk factors for cardiac sequelae is essential for early intervention.
Purpose:
- To describe the clinical and laboratory findings of Kawasaki disease in a specific patient cohort.
- To determine the incidence of cardiac complications, specifically coronary artery aneurysms.
- To identify risk factors associated with the development of coronary artery aneurysms.
Summary:
- A retrospective review of 76 children with Kawasaki disease revealed typical clinical and laboratory findings, including prolonged fever, rash, and elevated inflammatory markers.
- Coronary artery aneurysms were observed in 15.7% of patients, with mild mitral insufficiency and pericardial effusion in others.
- Male sex, urticarial rash, and C-reactive protein levels exceeding 10 mg/dL were identified as significant risk factors for coronary artery aneurysms.
Impact:
- This study highlights the importance of recognizing Kawasaki disease symptoms and risk factors for cardiac complications.
- Findings contribute to a better understanding of Kawasaki disease epidemiology and risk stratification in pediatric populations.
- Early identification of at-risk children can potentially lead to timely management and improved cardiovascular outcomes.
Introduction:
Kawasaki disease is an acute systemic vasculitis of childhood, of unknown origin, and is considered the leading cause of acquired heart disease in children. Therefore, it is important to know clinical manifestations and complications in children with Kawasaki disease in our environment and to look for risk factors for the development of cardiac complications.
Material And Methods:
Retrospective review of 76 children with Kawasaki disease evaluated from January 1997 to May 2008.
Results:
Of the patients studied, 64.5% were males. The mean age was 3 years and 4 months. The main clinical findings were fever (mean of 8.13 days), rash, bilateral non-exudative conjunctivitis, changes in lips and oral cavity, changes in the extremities, cervical lymphadenopathy and arthralgias. The most important laboratory findings were leucocytosis, thrombocytosis, elevated C-reactive protein and erythrocyte sedimentation rate, hypoalbuminaemia, hyperbilirubinaemia, elevated serum transaminases and sterile pyuria. Twelve of the patients (15.7%) developed coronary artery aneurysms, two patients had a mild mitral insufficiency and one patient with a mild pericardial effusion. There was one case of cholestatic hepatitis. All the complications were resolved without sequelae. Male sex (OR = 1.24), an urticarial exanthem (OR = 10.53) and a C-reactive protein > 10mg/dl (OR = 4.20) were identified as risk factors for coronary aneurysms.
Conclusions:
Our patients had the typical clinical and laboratory findings of Kawasaki disease. Mild coronary artery complications were observed in 15.7% of the patients. Male sex, an urticarial exanthem and an elevated C-reactive protein are risk factors for coronary aneurysms.
