Background
- Mucocutaneous lymph node syndrome
- Vasculitis of unknown etiology
- Peaks at 18-24 months
- Rare in <4mo, >5yr
- Leading cause of acquired heart disease in children
- Coronary aneurysm more common in incomplete than in classic KD
Clinical Features
- Fever that is high, abrupt
- Rash often seen in perineum; accompanies onset of fever
- Maculopapular most common; vesicles not seen
- Cardiac complications develop early on
- Coronary artery aneurysm development most prevalent as fever lessens
Associated Symptoms
- Cardiac
- Coronary aneurysm
- Most develop during 3-4th week of illness
- May lead to MI (leading cause of death)
- Myo/pericarditis
- Pericardial effusion
- LV dysnfunction
- Valvular dysfunction
- Dysrhythmias
- Coronary aneurysm
- Labs
- Elevated ESR/WBC/LFTs/Plts
- Aseptic meningitis
- Urethritis
- Anemia
- RUQ pain, large GB (hydrops)
Differential Diagnosis
Pediatric fever
- Upper respiratory infection (URI)
- UTI
- Sepsis
- Meningitis
- Febrile seizure
- Juvenile rheumatoid arthritis
- Pneumonia
- Acute otitis media
- Whooping cough
- Unclear source
- Kawasaki disease
- Neonatal HSV
- Specific virus
Diagnosis
Work-Up
- CBC
- LFTs
- ESR, CRP
- Blood culture
- UA
- ECG
- TTE (Coronaries, LV, valves)
- Red Top "Kawasaki Serum to CBR"
