A great summary of a rare, but important illness to consider in children with prolonged fevers. Kawasaki disease is a vasculitis to small and medium vessels, often occurring in childhood. While most children recover, there are important cardiac complications that need to be considered. Treatment with IVIG within the first 10 days of illness has been shown to reduce the prevalence of coronary artery aneurysms. In fact, untreated disease has been associated with an incidence of coronary artery aneurysm as high as 25%. [1]
The diagnosis of this disease process is challenging as there are no definitive testing methodologies and even the etiology of the systemic inflammatory process remains unknown. While most guidelines include 5 days of fever, the 2017 American Heart Association Scientific Statement indicates that 4 days of fever with the corresponding clinical features can be diagnostic. Moreover, in rare instances experienced clinicians have been able to make the diagnosis as early as 3 days. [1] In clinical practice, the clinical pathways at leading children’s hospitals use 4 days as a threshold for evaluation with the presence of 4 or 5 principal clinical features are present. [2,3] However, the standard practice continues to be 5 days for the classic diagnosis.
With high clinical suspicion for Kawasaki Disease, transfer to a pediatric hospital should be considered with consultations with Infectious Disease, Cardiology, and Rheumatology. It is important to have a high clinical suspicion for Kawasaki disease in children with prolonged fevers.
