慢性肾小球肾炎的原因尚未明瞭。在出现蛋白尿病人的肾组织活检中,几乎都见到肾小球有免疫球蛋白的沉着,因而考虑肾炎的发病跟免疫有关。再者多数病例的免疫球蛋白均呈颗粒状分布,估计是血中或体内抗原抗体反应产生的免疫复合物(IC)沉着于肾小球,通过各种介质而引起肾的质变。在急性一过性IC型肾炎中,也有与合并溶血性链球菌、疟疾等感染症那样查到原 The cause of chronic glomerulonephritis is unclear. In patients with proteinuria renal biopsy, almost all see glomerular immune globulin calm, so consider the incidence of nephritis and immune-related. In most cases, the immunoglobulins are distributed in the form of granules. It is estimated that immune complexes (ICs) produced by the reaction of antibodies in blood or in vivo are deposited on the glomerulus and cause mass changes of the kidney through various mediators. In acute transient IC nephritis, there are also merged with hemolytic streptococcus, malaria and other infectious diseases as found in the original
