A rare glomerular disease, histologically characterized by glomerular mesangial deposits of IgA, often accompanied by IgG and complement C3 as well as mesangioproliferative changes, clinically mostly manifesting as oligosymptomatic glomerulonephritis, possibly infection-triggered macrohematuria and a variable course ranging from spontaneous remission to slow or rarely rapid progression to kidney failure.
