摘要: 目的 探讨HIV/HCV共感染者外周血辅助性T细胞17(Th17)及白细胞介素(IL)-17A的免疫调节作用。方法 随机选取HIV/HCV共感染者、HIV感染者、HCV感染者和健康人各30例,使用流式细胞仪检测外周血CD4+T细胞数量和Th17数量,采用ELISA法检测血清IL-17A水平。结果 HIV感染者和HIV/HCV共感染者CD4+T淋巴细胞分别为(310.23±114.35)个/μl和(218.42±112.47)个/μl,均较健康人明显降低[(735.46±121.52)个/μl,P<0.05],HIV/HCV共感染者较HIV感染者CD4+T淋巴细胞更低(P<0.05),HCV感染者CD4+T淋巴细胞数为(719.47±123.72)个/μl,与健康人比较无显著性差异;HIV感染者Th17百分比和IL-17A水平分别为(2.48±0.90)%,和(25.18±12.63)pg/ml,均较健康人显著降低[(3.95±1.23)%和(39.15±16.30)pg/ml,P<0.05],HCV感染者Th17百分比和IL-17A为(5.48±0.90)%和(45.24±15.72)pg/ml,显著高于健康人(P<0.05),而HIV/HCV共感染者Th17百分比为(1.76±0.42)%,IL-17A为(16.49±7.54)pg/mL,均显著低于HIV感染者[(2.48±0.90)%和(25.18±12.63)pg/mL,P<0.05]。结论 合并HCV感染可能通过影响Th17及其细胞因子IL-17A进一步影响HIV患者的免疫功能。

Abstract: Objective To explore the changes in Thl7 cell counts and serum IL-17A levels in HIV/HCV co-infected patients. Methods Thirty HIV/HCV co-infected patients,30 HIV infected patients,30 HCV infected patients and 30 healthy subjects were selected in this study. The percentage of CD4+T cells and Th17 cells in peripheral blood,and IL-17A in sera were detected by FCM and ELISA,respectively. Results The percentage of CD4+T cells in HIV and HIV/HCV co-infected patients were (310.23±114.35)/μl and(218.42±112.47)/μl,respectively,both were significantly lower than that in the healthy controls[(735.46±121.52)/μl,P<0.05],while the percentage of CD4+T cells in HIV/HCV co-infected group was even lower than in HIV infected patients(P<0.05); There was no significant difference in CD4+T cells between HCV infected patients[(719.47±123.72)/μl] and the controls;The percentage of Th17 and serum level of IL-17A in HIV infected patients were(2.48±0.90)% and (25.18±12.63)pg/ml,significantly lower than those in the controls [(3.95±1.23)% and(39.15±16.30)pg/ml,P<0.05];The percentage of Th17 and serum level of IL-17A in HCV infected patients were(5.48±0.90)% and(45.24±15.72)pg/ml,significantly higher than those in the controls(P<0.05);The percentage of Th17 and serum level of IL-17A in HIV/HCV co-infected patients were(1.76±0.42)% and(16.49±7.54) pg/ml,both significantly lower than those in HIV infected patients[(2.48±0.90)% and (25.18±12.63)pg/mL,P<0.05]. Conclusions Co-infection of HCV may influence the immune response in HIV infected patients,which might lead to the involvement of Th17 and IL-17A cytokine.
