没有特殊的治疗方法可以逆转肝硬化的肝损伤。本研究旨在探讨HBV和HCV诱导肝硬化的免疫状态及其相关性。采用流式细胞术分析42例hbv -肝硬化和40例hcv -肝硬化患者外周血淋巴细胞亚群(T、NK、调节性T细胞)表型和Th细胞因子分泌情况。肝硬化患者CD3+CD8+T细胞和NK细胞比例低于正常对照组,CD3+CD4+T细胞和Treg细胞比例高于正常对照组。肝硬化患者中Th2细胞因子(IL-6)水平升高,而hbv -肝硬化患者中只有Th1细胞因子(IFN-γ)水平升高。这些结果表明,除了IFN-γ水平外,肝硬化组之间没有差异。在肝硬化中,无论涉及哪种病毒,先天的适应性免疫细胞都可能存在缺陷。细胞因子失衡可能在肝炎后肝硬化的发展中起作用。
No specific treatment can reverse the liver injury in cirrhosis. This study aims to characterize immune status and correlations between cirrhosis induced by HBV and HCV. Phenotypes of peripheral blood lymphocyte subsets (T, NK, regulatory T cells) and Th cytokine secretion were analyzed using flow cytometry in 42 HBV-cirrhotic and 40 HCV-cirrhotic patients. Cirrhotic patients had a lower proportion of CD3+CD8+T cells and NK cells, while the proportion of CD3+CD4+T cells and Treg cells were higher than those of healthy controls. The levels of Th2 cytokine (IL-6) in cirrhotic patients were increased, while only the Th1 cytokine (IFN-γ) increased in HBV-cirrhotic patients. These findings show that there is no difference between the cirrhotic groups except in the IFN-γ level. In cirrhosis, defects in innate, adaptive immune cells are likely regardless of which virus is involved. A cytokine imbalance may play a role in the development of posthepatitic cirrhosis.
