抽象的

乙型肝炎病毒 (HBV) 是導致嚴重公共衛生威脅的急性和慢性肝炎的主要原因之一。眾所周知,細胞因子是調節免疫細胞分化、增殖和功能的重要化學介質,越來越多的證據表明免疫反應不足是導致 HBV 消除或持續存在的原因。該研究旨在確定 HBV 感染臨床過程中的細胞因子譜(IFN-γ、TNF-α、IL-2、IL-4、IL-6、IL-10 和 IL-17A)並研究與基因型的關聯.共有 66 份血漿樣本,其中 19 份來自急性乙型肝炎感染患者,47 份來自慢性乙型肝炎感染患者,通過生化測試、巢式 PCR、實時 PCR 和細胞因子進行了測試,使用商用 BD CBA 人 Th1/Th2/Th17 細胞因子試劑盒進行了評估。健康對照(10 名受試者)選自無肝病史的獻血者。在分析的基因型、病毒載量和細胞因子之間沒有發現相關性。與對照組相比,所有細胞因子在受感染個體中均顯示出更高水平的產生。通過 Spearman 相關係數發現細胞因子、IFN-Y、TNF、IL-10、IL-6、IL4 和 IL-2 之間存在中等至強的正相關。與慢性組和對照組相比,急性個體的 TNF (p = 0.009) IL-10 (p <0.001) 和 IL-6 (p <0.001) 更高,這些細胞因子可能參與病毒清除和預防慢性病。本文受版權保護。版權所有。

Abstract

The hepatitis B virus (HBV) is one of the leading causes of acute and chronic hepatitis representing a serious public health threat. Cytokines are known to be important chemical mediators that regulate the differentiation, proliferation and function of immune cells and accumulating evidence indicate that the inadequate immune responses are responsible for HBV elimination or persistency. The study aimed to determine the cytokine profiles (IFN-γ, TNF-α, IL-2, IL-4, IL-6, IL-10 and IL-17A) at the clinical courses of HBV infection and investigate the association with genotypes. A total of 66 plasma samples, 19 from patients with acute and 47 with chronic hepatitis B infection were tested by biochemical tests, nested-PCR, real-time PCR and cytokines were evaluated using a commercial BD CBA Human Th1/Th2/Th17cytokines kit. Healthy controls (10 subjects) were selected from blood donors with no history of liver diseases. No correlation was found between genotypes, viral load and cytokines analyzed. All cytokines showed higher levels of production among infected individuals when compared to the control group. A positive correlation classified as moderate to strong was found between cytokines, IFN-Y, TNF, IL-10, IL-6, IL4 e IL-2 through Spearman's correlation coefficient. TNF (p = 0.009) IL-10 (p <0.001) and IL-6 (p <0.001) were higher in acute individuals compared to chronic and control group, theses cytokines could be involved in viral elimination and protection against chronicity.
