Pediatrics · Infections: Kawasaki disease

Sample item

A 3-year-old has 6 days of fever, bilateral non-purulent conjunctivitis, cracked red lips, cervical lymphadenopathy and swelling of the hands. What is the treatment of choice?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. IVIG 2 g/kg with aspirin

Kawasaki disease is a medium-vessel vasculitis in which fever of 5 or more days and 4 of 5 principal features confirm the diagnosis. IVIG 2 g/kg within the first 10 days reduces coronary aneurysm risk from about 25 percent to under 5 percent. Aspirin is given for its anti-inflammatory and later antiplatelet effect.

Option by option

  • A. Oral steroids alone

    Steroids alone are not standard first-line.

  • B. Observation

    Untreated disease leads to coronary aneurysms.

  • C. IVIG 2 g/kg with aspirin (correct)

    Correct. IVIG with aspirin is standard.

  • D. Penicillin

    Penicillin treats streptococcal infection and does not apply here.
