[摘要] 目的 通過檢測老年代謝綜合征(MS)人群的免疫球蛋白及T淋巴細胞亞群的變化分析其免疫狀態。 方法 采用透射比濁法測定免疫球蛋白(IgG、IgM和IgA)及流式細胞儀分析T淋巴細胞亞群(CD3+、CD4+、CD8+)在老年代謝綜合征和健康老年體檢者的分布情況。 結果 MS患者中4項指標均異常的占10.49%(30/286),3項指標異常的占29.37%(84/286),其中最多見的組合是體重指數(BMI)、高血壓和高血糖,兩項指標異常占60.14%(172/286)。老年代謝綜合征患者IgM、IgA及CD3+、CD4+均低於對照組,IgG和CD8+計數高於對照組,差異均有統計學意義,並且異常指標越多其免疫狀態越差。 結論 老年代謝綜合征患者由於肥胖、高血壓和胰島素抵抗等因素,使機體免疫細胞活性受到抑製,出現不同程度的非特異性免疫功能障礙。檢測老年代謝綜合征患者的血清免疫球蛋白及T淋巴細胞亞群可及時分析其免疫狀態,為後期的治療提供一定的參考。

[Abstract] Objective To test the changes of immunoglobulin and T lymphocyte subsets in elderly patients with metabolic syndrome (MS), and to analyze their immune state. Methods Transmission turbidimetry and flow cytometry were applied to measure and analyze the distribution of immunoglobulin (IgG, IgM and IgA) and T lymphocyte subsets in elderly patents with MS and healthy elderly controls. Results Among MS patients, patients with 4 abnormal indices accounted for 10.49% (30/286), patients with 3 abnormal indices accounted for 29.37% (84/286), in which the most commonly seen combination were BMI, hypertension and hyperglycemia. Patients with 2 abnormal indices accounted for 60.14% (172/286). IgM, IgA and CD3+, CD4+ in MS patients were all lower than those in the control group, the counts of IgG and CD8+ were higher than those in the control group, and the differences were all statistically significant. The more the abnormal indices, the worse the immune state. Conclusion Due to factors such as obesity, hypertension and insulin resistance in elderly MS patients, the activity of immunocytes is inhibited, and different degrees of non-specific immunity dysfunction occur. The tests of immunoglobulin and T lymphocyte subsets in elderly patients with MS are able to analyze their immune state timely, and to provide references for subsequent treatment.

代謝綜合征是一個組合的多種代謝性疾病,包括內髒性肥胖、胰島素抵抗、血脂異常和高血壓[1]。代謝綜合征可引起炎症和氧化應激反應增加心血管疾病、2型糖尿病、帕金森病和各種癌症的風險[2]。隨著我國人口的老年化,代謝綜合征已成為危害老年健康的常見疾病之一。代謝綜合征的存在使機體處於病理狀態,嚴重影響了患者的生存及生活質量。免疫係統的根本任務是識別和消滅外來分子入侵機體,一旦功能障礙就會導致心肺疾病和癌症等的發生。本研究對2012年10月~2014年10月本院老年體檢人員檢測免疫球蛋白和T淋巴細胞亞群,以了解老年代謝綜合征的免疫狀態。
1 資料與方法
1.1 一般資料
對2012年10月~2014年10月在我院體檢中心的亞健康中老年進行回顧性分析。總納入3852名體檢者,年齡60~80歲,平均(69.4±5.3)歲,經體檢診斷為代謝綜合征患者共計286例為MS組,其中女162例,男124例。以健康體檢者105例作為健康老年組,健康老年人標準參照1995年中華醫學會製定的關於健康老年的標準。兩組排除代謝綜合征以外的其他疾病,兩組年齡、性別等比較差異無統計學意義(P>0.05)。
