Infective Endocarditis: A Rare Trigger of Immunoglobulin A Vasculitis in an Adult.

Immunoglobulin A vasculitis (IgA vasculitis) is a small-vessel vasculitis usually triggered by bacterial or viral infections, antibiotics, and vaccinations. Although it is a disease of the pediatric population, it can occur in adults as well. We present a case of IgA vasculitis that was triggered by underlying infective endocarditis (IE). IE is a rare and fatal cause of the vasculitis that requires timely diagnosis and management to prevent catastrophic outcomes. Our patient was treated with antibiotics for IE, which led to the resolution of vasculitis.
