Kawasaki Disease Presenting with Bloody Diarrhea and Acute Renal Failure: First Case

Area of Science:

• Pediatric Rheumatology
• Pediatric Nephrology
• Vasculitis Research

Background:

• Kawasaki disease (KD) is the leading cause of acquired heart disease in children, potentially leading to severe morbidity and mortality.
• Delayed diagnosis of KD, often due to atypical presentations, significantly increases the risk of serious complications.
• Currently, no definitive blood test exists for KD, necessitating clinical suspicion for diagnosis.

Observation:

• This report details an unusual case of Kawasaki disease presenting with significant gastrointestinal and renal symptoms.
• The patient exhibited bloody diarrhea and acute renal failure, mimicking other conditions.
• These atypical manifestations highlight the diagnostic challenges associated with Kawasaki disease.

Findings:

• The case underscores that Kawasaki disease can manifest with severe renal involvement, such as acute kidney injury.
• Bloody diarrhea, while uncommon, can be a presenting symptom in atypical Kawasaki disease cases.
• Prompt recognition and treatment are vital, even with non-classic symptoms.

Implications:

• Clinicians should maintain a low threshold for considering Kawasaki disease in children with unexplained fever and unusual symptoms, including renal and gastrointestinal issues.
• Recognizing rare presentations of KD is essential for timely intervention and preventing long-term cardiovascular sequelae.
• Further research into the diverse clinical spectrum of Kawasaki disease is needed to improve diagnostic accuracy.
