Methods: Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of IL-33, IL-37, C-reactive protein (CRP), and procalcitonin (PCT) in the serum of 30 patients with high eosinophil counts, 30 patients with moderate eosinophil counts, 34 patients with low eosinophil counts, and 30 healthy individuals.

Results: The expression levels of serum IL-33, IL-37, CRP, and PCT in the COPD group were significantly higher than those in the healthy control group (P 1%pred and FEV1/FVC were significantly lower than those in the control group (P 1%pred and FEV1/FVC further decreased (P 1%pred and FEV1/FVC (P < 0.05). Conclusion: IL-33 and IL-37 may be closely related to the progression of COPD and may become new indicators for clinical diagnosis and assessment of disease severity in COPD, as well as providing new targets for clinical intervention.展开更多
