The term immunoglobulin A nephropathy (IgA nephropathy or IgA N) refers to a primary glomerular disease characterized by the dominant or co-dominant, diffuse, and generalized mesangial deposition of IgA, often accompanied by deposition of IgG and the C3 component of complement in a similar distribution (Donadio and Grande, 2004; Barratt and Feehally, 2005; Tomino, 2007; Glassock, 2008; Lai, 2008). In the past, it has also been referred to as Berger's disease, to signify the senior author of the original publication describing the disorder that first appeared more than 4 decades ago in September of 1968 (Berger and Hinglais, 1968). IgA N is most likely the commonest primary glomerular disease in the developed world (D’Amico, 1987). The disease is characterized principally by episodic glomerular hematuria often with persistent proteinuria of a variable degree. It usually runs an indolent course, but may lead to end-stage renal disease (ESRD) in about 30–50% of cases after 25 years or more of follow-up.
