抗核抗体阳性患者外周血淋巴细胞亚群结果分析

目的探讨抗核抗体(ANA)阳性患者外周血淋巴细胞亚群表达水平在自身免疫性疾病(AID)中的临床应用价值。方法选取200例ANA阳性患者和196例ANA阴性患者分别作为试验组和对照组,其中试验组采用间接免疫荧光试验(IFA)和免疫印迹试验(LIA)检测ANA,并根据检测结果分为IFA组和LIA组,同时采用流式细胞术检测各组外周血T淋巴细胞、辅助性T淋巴细胞、细胞毒性T淋巴细胞、NK淋巴细胞和B淋巴细胞绝对值,对检测结果进行统计分析。结果试验组辅助性T淋巴细胞、NK淋巴细胞、B淋巴细胞绝对值明显低于对照组,差异有统计学意义(P0.01);试验组内,IIF组辅助性T淋巴细胞、NK淋巴细胞绝对值明显低于LIA组,差异有统计学意义(P0.01)。结论外周血淋巴细胞亚群可以作为AID诊疗过程中的重要检测指标。

Analysis of peripheral blood lymphocyte subsets in patients with antinuclear antibody positive

Objective To investigate the clinical application value of peripheral blood lymphocyte subsets expression levels in autoimmune disease(AID) among the patients with antinuclear antibody(ANA) positive .Methods 200 patients with ANA positive and 196 patients with ANA negative were selected as the experimental group and control group respectively .The experimental group adopted indirect immunofluorescence assay (IFA) and immunoblotting assay(LIA) for detecting ANA ,moreover divided into the IFA group and LIA group according to the detection results .Meanwhile the flow cytometry was adopted to detect peripheral blood T lymphocytes ,helper T lymphocytes ,cytotoxic T lymphocyte ,NK lymphocytes and B lymphocytes absolute values of each group .The detection results were statistically analyzed .Results Helper T lymphocytes ,NK lymphocytes and B lymphocytes absolute values in the experimental group were significantly lower than those in the control group ,the differences were statistically significant(P＜0 .01);in the experimental group ,helper T lymphocytes and NK lymphocytes absolute values in the IIF group were significantly lower than those in the LIA group ,the differences were statistically significant (P＜0 .01) .Conclusion Peripheral blood lymphocytes subsets can serve as the important detection indicators during the diagnosis and treatment process of AID .
