A Child with COVID-19 and Immunoglobulin A Vasculitis

Area of Science:

• Pediatric Infectious Diseases
• Pediatric Rheumatology
• Pediatric Gastroenterology

Background:

• Immunoglobulin A (IgA) vasculitis, formerly Henoch-Schönlein purpura, is the most common childhood systemic vasculitis.
• Coronavirus disease 2019 (COVID-19) has been associated with various thrombotic and inflammatory complications, including vasculitis, in adults and children.

Observation:

• A pediatric patient presented with progressive abdominal pain, rash, and hematochezia.
• Laboratory findings revealed elevated D-dimer and abnormal inflammatory markers.
• The patient was diagnosed with both IgA vasculitis and COVID-19.

Findings:

• This case represents the first reported pediatric instance of COVID-19 associated with IgA vasculitis.
• The clinical presentation included symptoms typical of IgA vasculitis alongside confirmed SARS-CoV-2 infection.

Implications:

• This case underscores the potential for COVID-19 to trigger or exacerbate IgA vasculitis in children.
• Clinicians should consider COVID-19 in the differential diagnosis of pediatric patients presenting with vasculitic symptoms.
• Further research is needed to understand the precise mechanisms linking SARS-CoV-2 infection and IgA vasculitis in pediatric populations.
