7124—Direct immunofluorescence and correlates of systemic disease in adult Henoch-Schönlein purpura

Introduction: IgA vasculitis, formerly called Henoch-Schönlein purpura (HSP), is a systemic vasculitis caused by the deposition of IgA in multiple organ systems, commonly leading to renal, gastrointestinal, and joint manifestations. In adults, renal disease is more severe and occurs more often. The primary objective of this study was to characterize clinical and direct immunofluorescence (DIF) findings with systemic disease in adults with HSP.
