IgA Vasculitis Associated With Levofloxacin Use in an Adult Female: A Case Report.

Immunoglobulin A (IgA) vasculitis, once known as Henoch-Schönlein purpura in recognition of the physicians who first identified it, is an acute form of vasculitis, associated with a deposition of immune complexes, self-limited that affects small-caliber vessels. It usually occurs in children and rarely in adults. This disease can be induced by multiple factors such as exposure to certain infectious antigens such as viruses or bacteria, drugs, and toxins, and even genetic predisposition has been described.
