Henoch-Schönlein purpura primarily affects which age group?

• A. Adults over 50
• B. Children aged 3 to 10
• C. Teenagers
• D. Infants under 1

Answer: (B)

Henoch-Schönlein purpura (HSP), also known as IgA vasculitis, predominantly affects children, particularly those between the ages of 3 and 10. This condition is characterized by a systemic small-vessel vasculitis that often presents with a triad of symptoms: palpable purpura (typically on the buttocks and legs), abdominal pain, and arthralgia or arthritis. The immunological mechanisms underlying HSP are thought to be related to the deposition of IgA-enriched immune complexes in small blood vessels, which is most common during early childhood. While HSP can technically occur in individuals of any age, its prevalence significantly decreases after childhood, making children in this specific age range the primary demographic affected. It is less frequently seen in adults, teenagers, or infants, which is why the choice indicating children aged 3 to 10 is recognized as the most accurate. This age group represents the peak incidence rate, highlighting the importance of recognizing HSP symptoms in pediatric practices.
