A Case Series of Kawasaki Disease in Children With Sickle Cell Disease.

Prompt recognition and treatment of presumed bacterial infection in febrile children with sickle cell disease is necessary due to splenic dysfunction and impaired immune response. However, fever may be a manifestation of a noninfectious process, and health care providers must consider alternative sources. We describe 2 cases of children with sickle cell disease and persistent fevers, ultimately diagnosed with Kawasaki disease. These cases provide examples of an acute febrile illness that could lead to serious consequences if differential diagnoses are not considered and treatment is delayed.
