摘要:

目的: 观察阿米巴肝脓肿患者红细胞免疫功能和血清中细胞因子水平的变化。方法:采用红细胞C3b受体花环(RBC-C3bRR)及免疫复合物花环(RBC-ICR), 分别计算其花环率, 测定红细胞免疫功能; 用双抗体夹心ELISA法测定可溶性白细胞介素2受体(IL-2R)、肿瘤坏死因子(TNFα)、白细胞介素6(IL-6)及白细胞介素8 (IL-8); 用流式细胞仪测定外周血CD4 及CD8 细胞水平。结果: 40 例患者血清IL-2R (672.48±291.52 U/ml)、TNFα(0.874±0.452 ng/ml)、IL-6(0.198±0.021 ng/ml) 及IL-8 (0.648±0.075 ng/ml) 均显著地高于健康人; RBC-C3bRR 显著地低于健康人, 并与IL-2R呈负相关; 部分患者外周血T细胞亚群, 显示CD4 细胞减少, CD8 细胞增高, CD4/CD8 比值明显低于健康人。结论: 阿米巴肝脓肿患者红细胞和T 细胞的免疫功能均处于明显抑制状态。

Abstract:

AIM: To observe the changes in the red blood cell immune function (RBC-C3bRR, RBC-ICR) and serum soluble IL-2 receptor (IL-2R), tumor necrosis factor α(TNFα), IL-6, IL-8 in 40 patients with clinically confirmed amoebic liver abscess. METHODS: By sandwich ELISA and flow cytometry. RESULTS: Levels of IL-2R (672.48±291.52, U/ml), TNFα(0.874±0.452, ng/ml), IL-6 (0.198±0.021, ng/ml), IL-8 (0.648±0.075, ng/ml) in patients with amoebic liver abscess were significantly higher than those of healthy subject s, while RBC-C3bRR were significantly lower than that of healthy subjects . There was a negative correlation between the levels of IL-2R and RBC-C3bRR. The CD4/CD8 cell ratio (0.74±0.30) was markedly declined in peripheral blood of patients in comparison with healthy subjects (2.12) as detected by flow cytometry. CONCLUSION: The immune responses of both red blood cells and T cells were considerably suppressed in patients with amoebic liver abscess.
