ICD11: 4A44.5

  • Kawasaki 1967
  • Morbus Kawasaki, mucocutaneous lymph node syndrome, acute febrile mucocutaneous lymphadenopathy syndrome
  • Infection-associated diffuse vasculitis, which occurs predominantly in childhood
  • Characteristically affects the small and medium-sized vessels
    • Frequently affects the coronary arteries

  • Highest incidence is in Asia
  • Frequent vasculitis in childhood
  • 80% of patients are 1-5 years old
  • In the context of an infection, there is a cell-mediated reaction against endothelial antigens of the blood vessels (preferably medium-sized arteries).
  • 6 main symptoms
  1. High fever, without response to antibiotics
  2. Conjunctival involvement with photophobia and increased vascular injection
  3. Stomatitis (strawberry tongue
  4. Palmar and plantar erythema
  5. Polymorphic exanthema: scarlatiniform, morbilliform
  6. Cervical lymphadenopathy
  • Cardiac involvement (myocarditis/coronariitis/aneurysm)
  • Meningism
  • Bronchitis
  • Gastroenteritis
  • History
  • Clinical
  • Laboratory: elevated ESR, CRP, alpha2-globulins, leukocytosis, thrombocytosis, anaemia; positive detection of endothelial cell antibodies (AECA)
  • Biopsy
  • EGC/echocardiography, if necessary. Coronary angiography
  • To confirm the diagnosis, it requires the presence of 5 of the 6 major symptoms or 4 major symptoms and evidence of coronary aneurysm
  • Typical signs of vasculitis of the medium-sized and arteries
  • Necrotising vasculitis
.
  • Coronary aneurysms (20% of patients), myocardial infarction, myocarditis
.
  • If therapy is given, mortality is 1%
.
  • As a rule, the child should be admitted to hospital
  • Aspirin 30-60 mg / kg bw
  • Intravenous immunoglobulins 2g/kg bw within half the first week of illness or 7-10 days
