[Kawasaki disease: report of 6 cases]

Area of Science:

• Pediatrics
• Rheumatology
• Infectious Diseases

Background:

• Kawasaki disease is a critical pediatric illness primarily affecting children under five.
• Understanding geographic variations in disease presentation and demographics is crucial for accurate diagnosis.

Observation:

• Six pediatric cases of Kawasaki disease were analyzed, with ages ranging from 20 months to 6 years.
• Patients presented with symptoms consistent with international diagnostic criteria.
• An upper average age of 3 years was noted, aligning more closely with North American rather than Japanese cohorts.

Findings:

• One patient exhibited exanthema, while two others showed a positive rheumatoid factor, a previously undocumented observation in Kawasaki disease cases.
• All six children experienced a favorable clinical outcome without developing cardiovascular complications.

Implications:

• These findings suggest potential regional differences in Kawasaki disease demographics and clinical manifestations.
• The occurrence of rare symptoms like positive rheumatoid factor warrants further investigation into its diagnostic and prognostic significance.
• Early diagnosis and management appear effective in preventing severe cardiac sequelae in pediatric populations.
