The clinical manifestations are diverse, with hematuria being the most common. IgA nephropathy can be divided into two types: primary and secondary. The latter is often secondary to diseases such as liver cirrhosis, intestinal disease, arthritis, and herpes dermatitis. It also has significant IgA deposition in the glomerular mesangial area.
