Abstract

Tuberculous pleural effusions (TPEs) and malignant pleural effusions (MPEs) are difficult to differentiate between in certain clinical situations. Interleukin (IL)‑33 is a cytokine that participates in inflammatory responses and may have a role in pleural effusions. The present study aimed to investigate the concentrations and potential differential significance of IL‑33 in patients with TPE and MPE. IL‑33 levels in pleural effusion and serum samples were detected using sandwich enzyme‑linked immunosorbent assay in 23 patients with TPE and 21 patients with MPE. The concentration of IL‑33 (mean ± standard deviation) in the TPE patients (22.962±0.976 ng/l) was significantly higher than that in the MPE patients (12.603±5.153 ng/l; P<0.001; z=‑4.572); however, there was no significant difference in the serum level of IL‑33 in the patients with TPE compared with those with MPE (P>0.05). The concentration of IL‑33 in the pleural effusions was positively correlated with that in the serum samples in each group (TPE: r=0.563, P=0.05; MPE: r=0.535, P<0.05). The cut‑off value of pleural IL‑33 for TPE was 19.86 ng/l, which yielded a sensitivity of 0.869, a specificity of 0.905 and an area under the corresponding receiver operating characteristic curve of 0.903. The present study identified that the level of pleural IL‑33 is significantly increased in TPEs and may serve as a novel biomarker to differentiate between patients with TPE and MPE.
