Two Cases of Kawasaki Disease: Clinical Characteristics and Onset of Fever and Gastrointestinal Symptoms

BackgroundKawasaki disease (KD) is a prevalent form of systemic vasculitis that can damage various organs and systems in children. Typical KD is not difficult to diagnose in clinical practice. In recent years, it has been shown that an increasing number of children do not satisfy the diagnostic criteria for typical KD. This condition is known as incomplete KD (IKD). It is challenging to promptly diagnose and treat such children in clinical practice. Case DescriptionA 10-year-old girl was admitted to the hospital due to fever and abdominal pain. She presented with shock symptoms. An enhanced abdominal computed tomography scan revealed intestinal pneumatosis, effusion, and gallbladder enlargement, indicating intestinal obstruction. Due to the poor outcome following an emergency laparoscopic cholecystectomy, IKD was suspected. A 3-month-old male pediatric patient was admitted to the hospital due to a fever. Patchy, congestive rashes formed on the patient's body as KD progressed. IKD was suspected based on the clinical signs of fever, rash, and hyperemia of the lips. The two patients were then treated with human immunoglobulin and aspirin treatment. The prognosis for the two children was favorable following prompt treatment. ConclusionDue to the fact that IKD is frequently misdiagnosed, it is vital to (1) improve the patient prognosis for the early identification of children with KD with prolonged fever and anti-infection failure as the initial manifestation and (2) perform timely diagnosis and comprehensive treatment.
