乙型肝炎相关性肾炎是乙型肝炎抗原引起的免疫复合物肾炎。乙型肝炎抗原至少有四种:(1)乙型肝炎表面抗原(HBsAg),(2)乙型肝炎核心抗原(HBcAg),(3)乙型肝炎e抗原(HBeAg),(4)DNA多聚酶,均有可能结合相应抗体形成免疫复合物,沉积在肾小球内。但临床上不论在肾小球或血清内,均以HBsAg的检出率最高,故以往有人称之为乙型肝炎表面抗原性肾炎,这种提法是不够全面的。乙型肝炎相关性肾炎的发病率与当地乙型肝炎的流行情况密切相关,截至1977年止,文献中经肾活检
Hepatitis B-related nephritis is an immunocomplex nephritis caused by hepatitis B antigen. There are at least four hepatitis B antigens: (1) hepatitis B surface antigen (HBsAg), (2) hepatitis B core antigen (HBcAg), (3) hepatitis B e antigen (HBeAg) , Are likely to bind the corresponding antibodies to form immune complexes, deposition in the glomeruli. But clinically in the glomerular or serum, are the highest detection rate of HBsAg, so in the past called hepatitis B surface antigen nephritis, this formulation is not comprehensive enough. The incidence of hepatitis B-related nephritis is closely related to the prevalence of hepatitis B. As of 1977, the literature by the renal biopsy
