摘要:

目的: 探讨合并2型糖尿病对结核性胸膜炎患者外周血及胸腔积液结核感染T细胞斑点试验(T-SPOT.TB)检测结果的影响。方法: 收集2016—2021年西安市胸科医院收治的诊断为结核性胸膜炎的444例患者,依据是否合并2型糖尿病,分为结核性胸膜炎合并2型糖尿病组(合并糖尿病组;116例)和未合并糖尿病的结核性胸膜炎组(非糖尿病组;328例)。分别采集两组患者抗结核药物治疗前胸腔积液和外周血标本,进行T-SPOT.TB检测,分析两组患者T-SPOT.TB检测结果的差异。结果: 合并糖尿病组和非糖尿病组患者外周血T-SPOT.TB检测阳性率分别为46.55%(54/116)和56.10%(184/328),差异无统计学意义(χ2=3.140,P=0.076);胸腔积液T-SPOT.TB检测阳性率分别为65.52%(76/116)和88.41%(290/328),合并糖尿病组明显低于非糖尿病组,差异有统计学意义(χ2=31.025,P<0.001)。合并糖尿病组和非糖尿病组患者胸腔积液T-SPOT.TB检测阳性率均高于外周血,差异均有统计学意义(χ2=4.845,P=0.028;χ2=12.848,P<0.001)。结论: 当结核性胸膜炎患者合并2型糖尿病时,胸腔积液T-SPOT.TB检测阳性率降低,但仍高于外周血T-SPOT.TB检测结果;建议考虑优先行胸腔积液T-SPOT.TB检测,以提高阳性检出率。

Abstract:

Objective: To investigate the effect of type 2 diabetes mellitus on the results of T-cell spot test for tuberculosis infection (T-SPOT.TB) of the peripheral blood and pleural effusion in patients with tuberculous pleurisy. Methods: According to whether complicated with type 2 diabetes mellitus, 444 tuberculous pleurisy patients from Xi’an Chest Hospital between 2016 and 2021 were divided into tuberculous pleurisy complicated with type 2 diabetes mellitus group (n=116) and tuberculous pleurisy without type 2 diabetes mellitus group (n=328). The pleural effusion and peripheral blood specimens of the two groups before medical treatment were collected for T-SPOT.TB, and the results were compared. Results: The positive rates of peripheral blood T-SPOT.TB were 46.55% (54/116) in the tuberculous pleurisy complicated with type 2 diabetes mellitus group and 56.10% (184/328) in the tuberculous pleurisy without type 2 diabetes mellitus group, respectively, and there was no significant difference between the two groups (χ2=3.140, P=0.076). The positive rate of pleural effusion T-SPOT.TB in the tuberculous pleurisy complicated with type 2 diabetes mellitus group was significantly lower than that in the tuberculous pleurisy without type 2 diabetes mellitus group (65.52% (76/116) vs. 88.41% (290/328), χ2=31.025, P<0.001). By T-SPOT.TB, the positive rates in pleural effusion were significantly higher than those in peripheral blood in both two groups (χ2=4.845, P=0.028; χ2=12.848, P<0.001). Conclusion: When tuberculous pleurisy patients complicated with type 2 diabetes mellitus, the positive rate of T-SPOT.TB in pleural effusion was decreased, but it was still higher than that in peripheral blood. Pleural effusion T-SPOT.TB detection was recommended to improve the positive detection rate.
