Insights
Kawasaki disease (KD) is likely underdiagnosed in Brazil. Early diagnosis and referral are crucial, as delayed diagnosis in this study led to coronary aneurysms in 18.5% of pediatric patients.
Area of Science:
- Pediatrics
- Infectious Diseases
- Cardiology
Background:
- Kawasaki disease (KD) is a critical pediatric illness, particularly concerning in developing nations.
- Delayed diagnosis and treatment of KD can lead to severe cardiac complications, including coronary artery aneurysms.
- Underdiagnosis of KD in Brazil may be prevalent, necessitating improved awareness and diagnostic protocols.
Purpose of the Study:
- To evaluate the timeliness and accuracy of referrals for children with suspected Kawasaki disease in Brazil.
- To determine the incidence of coronary aneurysms in pediatric patients with KD in the studied cohort.
- To emphasize the importance of early diagnosis for mitigating KD complications.
Main Methods:
- A prospective cohort study involving 70 children admitted with Kawasaki disease between April 2002 and April 2007.
- Analysis of referral timing and diagnostic accuracy upon admission.
- Echocardiographic assessment for the detection of coronary aneurysms.
Main Results:
- Only 45.7% of children were referred during the acute phase of Kawasaki disease.
- A mere 21.4% of referred children received the correct diagnosis initially.
- Coronary aneurysms were identified in 13 (18.5%) of the studied pediatric patients.
Conclusions:
- Kawasaki disease is likely underdiagnosed in Brazil due to delayed referrals and misdiagnoses.
- A high index of suspicion is vital for pediatricians to ensure timely diagnosis of KD.
- Early detection and appropriate management of KD are essential to prevent life-threatening cardiovascular sequelae.
Abstract:
This is a prospective study of a cohort of 70 children with Kawasaki disease (KD) admitted from April 2002 to April 2007 to a tertiary hospital in Brasilia, Brazil. Of the 70 children, only 32 (45.7%) were referred during the acute phase of the disease and only 15 (21.4%) were referred with the correct diagnosis. Coronary aneurysms were detected in 13 (18.5%). A high suspicion index is essential in order to detect new cases as KD is probably underdiagnosed in Brazil and other developing countries, and an early diagnosis will dramatically decrease its life-threatening complications.
