Adult Henoch-Schonlein Purpura

Dr. Kiefer presented a fascinating case of Henoch-Schonlein Purpura presenting in a patient with a complex medical history who received antibiotics and presented with new renal failure, unique “palpable purpura” rash, and hypotension. While more common in pediatric populations, HSP occurs in adults as well, and can be a result of drug reaction. While a trigger is only found in a minority of patients, in addition to medications, triggers for adult onset HSP can include infections.
