慢性乙型肝炎患者病毒基因组与乙型肝炎病毒e抗原、肝功能关系分析

摘要

Objective To study the relationship among hepatitis B viral genome (HBV‐DNA) ,hepatitis Be antigen(HBeAg) and liver function in chronic hepatitis B patients ,and to provide the reference for clinical treatment .Methods The quantitative levels of HBV‐DNA ,HBeAg ,alanine aminotransferase (ALT) and aspartate aminotransferase(AST) in 401 patients were analyzed and the correlation analysis between HBV‐DNA and HBeAg was performed .The grouping was performed according to the HBV‐DNA and HBeAg quantitative levels and the differences of ALT and AST levels were compared among the groups .Results (1) The correla‐tion existed between HBV‐DNA and HBeAg positive rate ,r=0 .671(P<0 .01);(2)when HBV‐DNA load reaching 105 copies/mL , serum ALT and AST levels showed significantly increased compared with the HBV‐DNA negative group and low load group ,the difference was statistically significant (P<0 .05);(3)when HBV‐DNA load was equivalent ,the difference of ALT and AST activity had no statistically significant difference between the HBeAg‐positive and HBeAg‐negative groups .Conclusion (1)HBeAg has a correlation with HBV‐DNA ;(2)the patients with higher HBV‐DNA load are easy to develop the liver function abnormality ;(3)the HbeAg existence situation has no obvious relation with the liver function .%目的：探讨乙型肝炎病毒基因组（HBV‐DNA）、乙型肝炎病毒e抗原（HBeAg）、肝功能的相关关系，为临床治疗提供参考。方法回顾分析401例患者的HBV‐DNA、HBeAg、丙氨酸氨基转移酶（ALT）、天冬氨酸氨基转移酶（AST ）水平，对 HBV‐DNA与 HBeAg进行相关性分析。根据患者的 HBV‐DNA、HBeAg水平进行分组，比较各组的ALT、AST水平差异。结果（1） HBV‐DNA与 HBeAg的阳性率存在相关性，相关系数 r＝0．671（P＜0．01）；（2）HBV‐DNA载量达105 copies／mL时，血清ALT、AST较HBV‐DNA阴性组及低载量组显著升高，差异有统计学意义（P＜0．05）；（3）在 HBV‐DNA载量相当时，HBeAg阳性组与阴性组ALT、AST活性差异无统计学意义（P＞0．05）。结论（1）HBeAg与HBV‐DNA具有相关性；（2） HBV‐DNA载量较高的患者容易出现肝功能异常；（3）HBeAg的存在情况与肝功能无显著相关性。
