General Discussion

IgA nephropathy is a chronic kidney disease that usually first appears during adolescence and young adulthood and often progresses to kidney failure. It usually follows a viral infection of the upper respiratory or gastrointestinal tracts. The major symptom is the passing of blood in the urine (hematuria). There may be associated pain in the loin area.
