一般认为IgA肾病是免疫复合物疾病的一种,其抗原多考虑为粘膜局部的感染。其部位有上呼吸道(扁桃体)、消化道、胆道、皮肤。抗原为各种病毒、细菌、食物。本症的一部是急性肾炎样病例。在病程中,以扁桃体炎为诱因,常见血尿。Miura等观察20例IgA肾病,发现70%的病例在扁桃体炎后血尿加重。因此,IgA肾病的发生、进展及恶化与上呼吸道感染明显相关。 It is generally believed that IgA nephropathy is a kind of immune complex disease, and its antigens are considered as mucosal local infections. The upper part of the respiratory tract (tonsils), digestive tract, biliary tract, skin. Antigen for a variety of viruses, bacteria, food. A part of this disease is acute nephritis-like cases. In the course of the disease, the cause of tonsillitis, common hematuria. Miura et al observed 20 cases of IgA nephropathy and found that 70% of cases were exacerbated by hematuria after tonsillitis. Therefore, IgA nephropathy, progression and deterioration of upper respiratory tract infection were significantly related.
