概括
乙型肝炎核心相关抗原 (HBcrAg) 是慢性乙型肝炎活动的敏感标记物,即使HBV DNA无法检测. 新的测定方法,包括临床测试,增强了HBcrAg.
科学领域:
- 肝病学和病毒学.
- 生物标志物开发和临床应用
背景情况:
- 乙型肝炎核心相关抗原 (HBcrAg) 表明肝脏内共封闭的圆形DNA活性.
- 当血清HBVDNA或乙型肝炎表面抗原在慢性乙型肝炎患者中无法检测时,HBcrAg是可检测的.
- 目前的国际预防母婴传播指南建议高病毒载荷的孕妇进行预防,但在全球范围内,HBV DNA量化通常是不可用的.
研究的目的:
- 审查HBcrAg在乙型肝炎病毒 (HBV) 管理中的临床价值.
- 突出完全自动化,敏感的HBcrAg测定 (iTACT-HBcrAg) 和临床检测 (POCT) 的实用性.
- 讨论HBcrAg作为HBVDNA的替代品,用于监测HBV的活性和预测肝细胞癌.
主要方法:
- 开发一种全自动化,高度敏感的HBcrAg测定方法 (iTACT-HBcrAg).
- 为资源有限的环境开发一个点照顾测试 (POCT) HBcrAg测定方法.
- 对HBcrAg应用的现有文献和临床数据的审查.
主要成果:
- iTACT-HBcrAg作为HBVDNA的验证替代品,用于监测HBV的活性和预测肝细胞癌.

Enzyme-Linked Immunosorbent Assay
In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.

Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
