摘要
目的探讨T淋巴细胞亚群、B淋巴细胞及NK细胞的变化在系统性红斑狼疮(SLE)发生和发展中的作用。方法选取解放军264医院和山西医科大学第二医院诊治的SLE 380例及健康体检者58例,SLE患者分为稳定期组157例、轻度活动期组79例、中度活动期组82例、重度活动期组62例。检测各组外周血中T、B淋巴细胞、NK细胞、Th、Ts细胞计数及百分比,并分析SLE患者外周血淋巴细胞亚群与SLE疾病活动指数(SLEDAI)的相关性。结果活动期SLE T、Th及NK细胞计数及百分比、Ts细胞计数低于健康对照组和稳定期组,B细胞百分比高于健康对照组和稳定期组(P<0.05)。T、Th、Ts、NK细胞计数、T细胞百分比与SLEDAI评分呈负相关,B细胞百分比与SLEDAI评分呈正相关(r=-0.347、-0.311、-0.326、-0.351、-0.318、0.455,P<0.05)。结论外周血淋巴细胞亚群的变化可以为SLE患者病情评估及诊治效果提供依据。
Objective To investigate the effects of T lymphocyte cell subsets,B-lymphocytes and NK cells changes in the pathogenesy and development of systemic lupus erythematosus（ SLE）. Methods A total of 380 inpatients with SLE and 58 healthy controls taking medical examination were recruited in this study,and then the SLE inpatients were divided into inactive SLE subgroup（ subgroup A,n = 157）,gentle active SLE subgroup（ subgroup B,n =79）,midrange active SLE subgroup（ subgroup C,n = 82） and severe active SLE subgroup（ subgroup D,n = 62）. The counts and percentages of T-lymphocytes,B-lymphocytes,Th,Ts and NK cells in peripheral blood were detected in the four groups. The correlations between peripheral-blood lymphocyte subsets and disease activity indexes of SLE（ SLEDAI）in SLE patients were also analyzed. Results In active subgroups,the values of counts and percentages of T,Th and NK cells and Ts cell count were significantly lower than those in control group,while B-lymphocytes percentage was significantly higher than those in control group and inactive SLE subgroup（ P〈0. 05）. The counts of T,Th,Ts,NK cells and percentage of T cell were negatively correlated with SLEDAI score,while percentage of B cell was positively correlated with SLEDAI score（ r =- 0. 347,- 0. 311,- 0. 326,- 0. 351,- 0. 318,0. 455,P〈0. 05）. Conclusion The changes of lymphocyte subsets in peripheral blood of SLE patients may be helpful in evaluating pathogenetic condition and diagnosis of the SLE.
