IgA肾病的病变主要在系膜部位,故又称系膜性IgA肾病。其在国外沿用的病名颇多,如IgA—IgG肾病、IgA相关肾小球肾炎、Berger病、血管系膜性IgA肾炎、良性反复发作性血尿和局灶性肾炎伴系膜IgA沉积等。由于目前国内尚不能普及肾穿刺活检、电镜检查、免疫荧光染色,故本病常被误诊为其它类型的肾小球疾病。 IgA nephropathy mainly in the mesangial lesions, it is also known as mesangial IgA nephropathy. The disease name used in many foreign countries, such as IgA-IgG nephropathy, IgA-related glomerulonephritis, Berger’s disease, vascular mesangial IgA nephritis, benign recurrent hematuria and focal nephritis with mesangial IgA deposition. Due to the current domestic can not popularize renal biopsy, electron microscopy, immunofluorescence staining, so the disease is often misdiagnosed as other types of glomerular disease.
