目的:观察全身型重症肌无力(myasthenia gravis, MG)患者血中T淋巴细胞亚群百分比的变化,分析其与患者症状加重或缓解间的关系。方法:采用流式细胞术分别检测51例全身型MG患者在病情加重及缓解的不同时期外周血中T淋巴细胞亚群百分比的变化,分析其与症状波动之间的关系,另设30名健康体检者为对照组。结果:加重期MG患者血中的CD4+CD25+CD127low/-调节性T淋巴细胞和CD4+CD45RA+原始T淋巴细胞百分比均明显低于对照组(5.54%±1.88%比7.95%±3.45%,P<0.05;11.42%±6.97%比 24.98%±7.86%,P<0.05);而MG患者加重期血中的CD4+CD45RO+T淋巴细胞百分比高于缓解期及对照组(35.06%±8.78%比30.82%±8.43%;35.06%±8.78%比30.09%±7.53%,P均<0.05)。采用受试者工作特征曲线(receiver operating characteristic curve,ROC曲线)分析淋巴细胞百分比在MG诊断中的价值,患者血中的CD4+CD25+CD127low/-调节性T淋巴细胞和CD4+CD45RA+T淋巴细胞诊断全身型MG发病的ROC曲线下面积(area under curve,AUC)分别为0.713和0.900(P<0.05);CD4+CD45RO+ T淋巴细胞诊断MG症状加重的AUC为0.675,其最佳临界值为32.06%。结论:检测调节性T淋巴细胞和CD4+CD45RA+T淋巴细胞百分比对全身型MG的发病具有一定诊断价值,而CD4+CD45RO+T淋巴细胞百分比与全身型MG患者的症状波动相关,有可能成为衡量其病情变化的标志物。

Objective: To investigate the relationship between changes of T lymphocytes and exacerbation and remission in patients with generalized myasthenia gravis (GMG). Methods: Flow cytometry was used to detect the change of T lymphocyte subsets in peripheral blood of 51 patients with GMG during different periods of exacerbation and remission, and analyzed the relationship between the changes of T lymphocytes and symptom fluctuations. Results: The percentage of CD4+CD25+CD127low/-regulatory T lymphocytes and CD4+CD45RA+naive T lymphocytes was significantly lower in exacerbation period than that in control group (P<0.05), whereas the percentage of CD4+CD45RO+ memory T lymphocytes in exacerbation period was significantly higher than that in remission period and control group(P<0.05). The AUC of CD4+CD25+CD127low/-regulatory T lymphocytes and CD4+CD45RA+naive T lymphocytes were 0.713 and 0.900, respectively. The AUC of CD4+CD45RO+ memory T lymphocytes in exacerbation period was 0.675 and the optimum critical value was 32.06%. Conclusions: Regulatory T lymphocytes and CD4+CD45RA+naive T lymphocytes have diagnostic value for GMG. CD4+CD45RO+ memory T lymphocytes are correlated with symptom aggravation and remission of GMG, and may be used as a marker for measuring the symptom fluctuation of myasthenia gravis.
