Immunoglobulin A nephropathy (IgAN) is a common cause of glomerulonephritis that can progress to end-stage renal disease (ESRD). IgA vasculitis, a systemic small vessel vasculitis, is a recognized secondary cause of IgAN. Although rare, rapidly progressive glomerulonephritis (RPGN) can occur in the context of IgA vasculitis, with drug-induced immune responses implicated in some cases.
Maramba et al. (Wed,) studied this question.
