概念:乙型肝炎相关性肾炎(简称乙肝肾炎)是感染乙型肝炎病毒(HBV)后引起的免疫性肾小球疾病,任何年龄均可发病,小儿多见。发病机理:当 HBV 进入人体,其抗原成分如 HBsAg、HBcAg 等可刺激人体免疫系统产生相应的抗体,抗原抗体结合成免疫复合物,随血循环到肾脏,潴留于肾小球基膜内侧及/或肾小球基膜外侧,激活补体,补体激活后产生多种活性物质如白细胞趋化因子等,吸引中性粒细胞,继而从 Concept: Hepatitis B-related nephritis (referred to as hepatitis B nephritis) is caused by the infection of hepatitis B virus (HBV) immune glomerular disease, any age can be disease, more common in children. Pathogenesis: When HBV enters the body, its antigenic components such as HBsAg and HBcAg can stimulate the body’s immune system to produce the corresponding antibodies that bind to the immune complex, circulate with the kidney, and retain inside the glomerular basement membrane and / or Glomerular basement membrane outside the activation of complement, complement activation produces a variety of active substances such as leukocyte chemokines, to attract neutrophils, and then from
