Diagnóstico precoce de doença de Kawasaki durante pandemia de COVID-19: relato de caso

Abstract

OBJECTIVE: To report the case of a patient with an early diagnosis of Kawasaki disease with an early-stage coronary aneurysm complication. Kawasaki disease is one of the most common primary vasculitis and is the main cause of acquired heart disease in children in developed countries. It is characterized by a multisystemic involvement of unknown etiology. High fever and persistent for more than five days, associated with polymorphic rash, tongue erythema with papillary prominence, edema of the extremities, bilateral conjunctivitis and cervical lymph node enlargement are characteristics of the disease, but they were also found in some patients with COVID-19 and in multisystem inflammatory syndrome. CASE REPORT: A 6-year and 1-month-old male patient with a 72-hour persistent fever report, polymorphic rash, gastrointestinal symptoms, evolving with bilateral conjunctival hyperemia without exudate, raspberry tongue, worsening of skin cutaneous and extremity edema. Echocardiogram with finding of coronary aneurysm. Treatment for Kawasaki disease was started with satisfactory therapeutic response and decreased coronary dilation. CONCLUSION: This report shows the importance of considering Kawasaki disease as a differential diagnosis in cases of febrile syndromes. Early diagnosis allows treatment to improve outcomes.
