Treatment of hepatitis C virus (HCV) infection based on peginterferon-α (pegIFNα) and ribavirin induces important changes in cytokine release and T cell activation.
Immune response to pegIFNα-ribavirin therapy was explored in patients coinfected by HCV and HIV.
Concentrations of 25 cytokines and CD8(+) T cell activation were monitored in HCV/HIV coinfected patients classified as sustained virological responders (SVR, n=19) and non-responders (NR, n=11).
High pretreatment concentrations of IP-10 (CXCL-10) and MCP-1 (CCL-2) were associated with a poor anti-HCV response. PegIFNα-ribavirin therapy increased CD8(+) T cell activation and induced significant changes in levels of eleven cytokines related to both Th1 and Th2 responses in SVR (IL-1β, IL-1RA, IL-4, IL-5, IL-6, IL-7, IL-12p40/70, IL-13, IP-10, eotaxin, MCP-1) but of only six cytokines in NR (IL-1β, IL-2, IL-5, IL-12p40/70, IL-13, eotaxin). The highest rise in MIP-1β and MCP-1 levels was observed four weeks after anti-HCV treatment initiation in SVR compared to NR (p=0.002 and p=0.03, respectively), whereas a decrease in IL-8 concentration was associated with treatment failure (p= 0.052).
Higher and broader cytokine responses to pegIFNα-ribavirin therapy were observed in SVR patients compared to NR. Changes in IL-8, MIP-1β, and MCP-1 serum concentrations may be associated with efficacy of pegIFNα- and ribavirin-based therapies in patients coinfected by HCV and HIV.
基于聚乙二醇干扰素-α(pegIFNα)和利巴韦林的丙型肝炎病毒(HCV)感染治疗可引起细胞因子释放和T细胞活化的重要变化。
探讨HCV和HIV合并感染患者对pegIFNα-利巴韦林治疗的免疫反应。
在分类为持续病毒学应答者(SVR,n = 19)和无应答者(NR,n = 11)的HCV/HIV合并感染患者中监测25种细胞因子的浓度和CD8(+) T细胞活化情况。
IP-10(CXCL-10)和MCP-1(CCL-2)的高治疗前浓度与抗HCV反应不佳相关。PegIFNα-利巴韦林治疗增加了CD8(+) T细胞活化,并在SVR患者中诱导了与Th1和Th2反应相关的11种细胞因子水平的显著变化(IL-1β、IL-1RA、IL-4、IL-5、IL-6、IL-7、IL-12p40/70、IL-13、IP-10、嗜酸性粒细胞趋化因子、MCP-1),但在NR患者中仅诱导了6种细胞因子的变化(IL-1β、IL-2、IL-5、IL-12p40/70、IL-13、嗜酸性粒细胞趋化因子)。与NR相比,SVR患者在抗HCV治疗开始后四周观察到MIP-1β和MCP-1水平的最高升高(分别为p = 0.002和p = 0.03),而IL-8浓度降低与治疗失败相关(p = 0.052)。
与NR患者相比,SVR患者对pegIFNα-利巴韦林治疗观察到更高和更广泛的细胞因子反应。IL-8、MIP-1β和MCP-1血清浓度的变化可能与基于pegIFNα和利巴韦林的疗法对HCV和HIV合并感染患者的疗效相关。
