血清及胸水中ADA、IL-2、IL-6、IL-10联检对结核性和癌性胸膜炎患者的诊断价值

目的:观察结核性和癌性胸膜炎两组患者血清和胸水ADA、IL-2、IL-6、IL-10的含量变化,能成为鉴别诊断试验。方法:结核性胸水组56例、癌性胸水组53例、正常对照组30例,分别测定血清和胸水中ADA、IL-2、IL-6、IL-10,并进行临床诊断的ROC曲线分析。结果:两组患者血清IL-6水平明显高于对照组,有显著性差异(P<0 05),结核性胸水组的ADA、IL-2、IL-6、IL-10明显高于癌性组,有显著差异(P<0 05),ROC曲线表明两组依次为ADA>IL-10>IL-6>IL-2。结论:胸水的ADA、IL-2、IL-6、IL-10的测定有助于两组的鉴别诊断,总的鉴别诊断价值依次为ADA>IL-10>IL-6 >IL-2,并且ADA与IL-10的联检可明显提高两组胸水的鉴别诊断价值。

Diagnostic Value of Combined Determination of Serum and Chest Fluid Adenosine Deaminase(ADA), IL-2, IL-6, IL- 10 Contents for Differentiation of Tuberculous From Malignant Pleural Effusion

Objective To investigate the possible diagnostic value of combined determination of serum and chest fluid contents of ADA, IL-2, IL-6, IL-10 in patients with tuberculous and malignant pleural effusion. Methods Serum and chest fluid ADA (with biochemical method), IL-2, IL-6, IL-10 (with ELISA) contents were measured in 56 patients with tuberculosis pleural effusion, 53 patients with malignant effusion and 30 controls (in serum only). The receiving operative characteristic (ROC) curve for each parameter was analyzed for study of respective area under curse (Auc). Results The serum IL-6 levels in both groups of patients were significantly higher than those in the controls (P<0.05). The chest fluid contents of ADA, IL-2, IL-6 and IL-10 in patients with tuberculous effusion were all significantly higher than those in patients with malignancies (P<0.05). The Auc in the ROC was largest in the cose of ADA, followed by IL-10, IL-6 with IL-2 the least. Conclusion Determination of chest fluid ADA, IL-2, IL-6, IL-10 contents was helpful in the differentiation of tuberculous from malignant pleural effusion. Combined determination of chest fluid ADA and IL-10 provided the highest accuracy rate for differentional diagnosis.
