The aim of this study was to investigate the diagnostic value of interleukin 22 (IL-22) and carcinoembryonic antigen (CEA) in tuberculous pleural effusions (TPEs) and malignant pleural effusions (MPEs). Pleural effusion samples from 56 patients were classified on the basis of diagnosis as TPE (n=28) and MPE (n=28). The concentration of IL-22 was determined by ELISA. Lactate dehydrogenase (LDH), adenosine dehydrogenase (ADA) and CEA levels were also determined in all patients. A significant difference was observed in the levels of ADA and CEA (P<0.01), but not in the levels of LDH (P>0.05) between TPE and MPE. The concentration of IL-22 in TPE was significantly higher compared to MPE (P<0.01). With a threshold value of 49 pg/ml, IL-22 had a sensitivity of 82.14% (23/28) and a specificity of 96.43% (27/28) for differential diagnosis. The combined detection of IL-22 and CEA had a sensitivity of 100% (28/28) and a specificity of 96.43% (27/28) to distinguish TPE from MPE. TPEs showed significantly higher levels of IL-22 compared to MPEs. The combined detection of IL-22 and CEA may be more valuable in the differential diagnosis between TPE and MPE.
本研究的目的是探讨白细胞介素22（IL-22）和癌胚抗原（CEA）在结核性胸腔积液（TPE）和恶性胸腔积液（MPE）中的诊断价值。将56例患者的胸腔积液样本根据诊断分为TPE组（n = 28）和MPE组（n = 28）。采用酶联免疫吸附测定法（ELISA）测定IL-22的浓度。同时测定所有患者的乳酸脱氢酶（LDH）、腺苷脱氢酶（ADA）和CEA水平。TPE组和MPE组之间ADA和CEA水平存在显著差异（P<0.01），但LDH水平无显著差异（P>0.05）。TPE组中IL-22的浓度显著高于MPE组（P<0.01）。以49 pg/ml为临界值，IL-22鉴别诊断的灵敏度为82.14%（23/28），特异度为96.43%（27/28）。IL-22和CEA联合检测鉴别TPE和MPE的灵敏度为100%（28/28），特异度为96.43%（27/28）。与MPE相比，TPE中IL-22水平显著更高。IL-22和CEA联合检测在TPE和MPE的鉴别诊断中可能更有价值。
