Severe esophagitis in a child with Henoch-Schönlein purpura presenting as protein-losing enteropathy

Area of Science:

• Pediatric Gastroenterology
• Pediatric Rheumatology
• Dermatology

Background:

• Protein-losing enteropathy (PLE) can present with diverse gastrointestinal symptoms.
• Henoch-Schönlein purpura (HSP) is a common childhood vasculitis often associated with skin and joint manifestations.

Observation:

• A 4-year-old boy presented with vomiting, diarrhea, and peripheral edema, diagnosed with protein-losing enteropathy.
• Endoscopy revealed severe esophagitis and duodenal ulcers, which resolved spontaneously with hospitalization.
• Post-discharge, the patient developed a characteristic rash and arthritis, indicative of Henoch-Schönlein purpura.

Findings:

• Skin biopsy confirmed leukocytoclastic vasculitis, consistent with Henoch-Schönlein purpura.
• The gastrointestinal symptoms and endoscopic findings preceded the classic presentation of HSP.
• This case highlights a potential link between severe gastrointestinal inflammation and the subsequent development of HSP.

Implications:

• This case suggests that severe gastrointestinal inflammation may precede or coincide with the onset of Henoch-Schönlein purpura.
• Early recognition of gastrointestinal manifestations in children presenting with vasculitic symptoms is crucial.
• Further research may elucidate the pathogenic mechanisms connecting gastrointestinal disease and Henoch-Schönlein purpura in pediatric patients.
