Epidemiology

IgAN is the commonest pattern of glomerulonephritis worldwide. It is diagnosed in 40% of all kidney biopsies performed in Asia, 20% of all kidney biopsies in Europe, and 10% of all kidney biopsies in the US.[10][11][12][13][14][15] These rates may differ, at least in part, due to differences in public health screening and biopsy practices. In countries with active screening programmes for kidney disease, and centres with a low threshold to perform a renal biopsy, the reported incidence of IgAN is higher, as more patients with mild disease are identified.
