IgA nephropathy is caused by a group of multiple causes with the same characteristics of the immune pathology of chronic glomerular disease. Clinically, about 40% ~ 45% of patients showed the naked eye or microscopic hematuria, 35% ~ 40% of patients showed microscopic hematuria with proteinuria, the rest presented as nephrotic syndrome and renal failure. IgA nephropathy is a common worldwide, glomerular disease, and its popularity in different continents, different countries or in a country very different in different regions, such as Asia, Japan, Singapore, IgA nephropathy accounts for the incidence of the primary Glomerular disease, 50%, while the western United States Indian low-incidence areas accounted for only 2%. Generally speaking, white, yellow was significantly higher than the incidence of black people. The incidence of our IgA nephropathy of primary glomerular disease accounted for 26% ~ 34%. Male to female ratio is about 2:1. Mainly of IgA nephropathy with hematuria There is no effect of treatment. Since the disease pathology type and extent of glomerular damage to the large difference. Therefore, we should closely observe the frequency of seizures in patients with gross hematuria, proteinuria level, with or without high blood pressure and renal function extent of the damage, but were taken to the corresponding control measures.


Its clinical manifestations mainly in four areas: 1. Episodic gross hematuria; 2. Mild proteinuria, most of <1g / 24 hours; 3. Hypertension; 4. Other manifestations, such as may occur with uremia uremia The clinical manifestations.
