colitis complicating Kawasaki disease in children: Two case reports

Abstract

Clostridium difficile infection is increasingly diagnosed in children with a wide clinical spectrum ranging from asymptomatic carriage to fulminant colitis. Symptomatic patients typically present with diarrhea, with or without blood, fever, and abdominal pain. Kawasaki disease, a vasculitis of unknown etiology, occurs primarily in young children. Establishing the diagnosis of Kawasaki disease can be challenging given the lack of a confirmatory diagnostic test or pathognomonic features as well as the appearance of symptoms over time rather than simultaneously. In addition, commonly occurring nonspecific associated symptoms, such as diarrhea and abdominal pain, may confound the clinical presentation. We present two cases of children with Kawasaki disease presenting with fever and Clostridium difficile colitis to illustrate the importance of keeping a high index of suspicion for Kawasaki disease.
