hello kitty

Imagine: You are a 3 year old child. The world is your oyster. You are young (very young), carefree, and you have a need for speed. Times are good. Until you get a fever.. for 6 freakin’ days! Your whole body just ain’t like it use to be–you have a rash, a fever, and painful hands, and your lips are so dry and painful that you can’t even kiss your Hello Kitty doll goodnight. You were cruising through childhood in your decked-out Hello Kitty Mobile so fast that you CRASHed and BURNed. Meow.

 

What is this disease? What causes it?

Kawasaki disease!

KD is a vasculitis, not an infectious disease, and the exact cause is unknown. Incidence is between 5 months – 5 years with peak at 18-24 months.

 

What are the criteria for diagnosis?

You can remember with the mnemonic CRASH and Burn

  • Conjunctivitis (nonexudative, bilateral)
  • Rash (polymorphous/nonspecific)
  • Adenopathy (cervical nodes)
  • Strawberry tongue/ mucosal changes – “mucositis” with cracked red lips or oral erythema (don’t necessarily need “strawberry tongue,” but there must be some mucosal/oral inflammation)
  • Hand edema or erythema; may also desquamate and can involve feet 
  • “Burn” = fever. Feel the bern, y’all.

Kawasaki-Disease-symptoms

Criteria for classic disease are fever for 5 days plus 4 or the 5 criteria above. 

 

Patients can also have incomplete disease defined by fever for 5 days, at least 2 criteria, an elevated ESR (> 40) OR CRP (>3.0) PLUS positive echo OR 3 (or more) lab findings below:

  • albumin low (< 3.0)
  • anemia
  • elevated ALT
  • increased platelets (> 450K after fever for 7 days)
  • increased WBC (>12K)
  • pyuria

 

What is the treatment and ED dispo?

Admission. Remember they are at risk of coronary aneurysm and need high-dose aspirin therapy: 80mg/kg/day divided q6 hours for 2 weeks, followed by 3-5mg/kg/day for 6 weeks. They also should get IVIG. They will need an echo as an inpatient to assess for aneurysm and wall abnormalities.
