Serum levels and clinical significance of IL-17,IL-23 in chronic obstructive pulmonary disease
Objective:To investigate serum levels and clinical significance of IL-17
IL-23 in chronic obstructive pulmonary disease(COPD).Methods:Serum IL-17 and IL-23 levels were detected in 90 subjects including 60 COPD(30 acute exacerbation and 30 stable) and 30 healthy controls by ELISA.The percentage of blood neutrophils N(%) and the percentage of forced expiratory volume in one second of predicted value(FEV1%) were measured respectively by the department of Clinical Laboratory and the Lung Function Laboratory of Lanzhou University Second Hospital.Results:①IL-17 and IL-23 serum levels were significantly different(P<0.05) among AECOPD
stable phase COPD and healthy controls;②N(%) was statistically significant between AECOPD and stable phase COPD(P<0.05) as well as between AECOPD and healthy controls(P<0.05);③FEV1% was statistically significant(P<0.05) among AECOPD
stable phase COPD and healthy controls;④There was a linear correlation between serum IL-17 and IL-23 in all COPD patients(r=0.449
P=0.000<0.001);⑤There was a linear correlation between serum IL-17 levels and N(%) in all COPD patients(r =0.273
P=0.035<0.05);⑥There was a negative linear correlation between IL-17 serum levels and FEV1% in all subjects(r=-0.510
P=0.000<0.001).Conclusion:IL-17 and IL-23 serum levels might be associated with inflammation in COPD and have some relevance to COPD clinical manifestations.
