Abstract
Purpose
Serum decoy receptor 3 (DcR3) level increases in chronic inflammatory diseases. The present study aimed to examine serum DcR3 and IL-6 levels in male patients with stable chronic obstructive pulmonary disease (COPD) and acute exacerbation of the disease and correlations between these markers and airflow limitation.
Methods
We measured serum DcR3 and IL-6 levels in 60 COPD patients [30 stable COPD (SCOPD), and 30 acute exacerbation of COPD (AECOPD)], and 30 control subjects and assessed their correlations with airflow limitation according to the COPD stage indicated by the global initiative for chronic obstructive pulmonary disease (GOLD) criteria, peripheral O2 saturation (SpO2), and COPD assessment test (CAT) score. We also tested associations between serum DcR3 levels and COPD patients’ clinical parameters.
Results
Both serum DcR3 and IL-6 levels increased with increasing severity of airflow limitation in SCOPD and AECOPD groups (P < 0.01 to 0.001). These markers also increased in patients with AECOPD compared with subjects in SCOPD group in GOLD stages III–IV (P < 0.05 to 0.001). In addition, there was a significant positive correlation between serum DcR3 level and IL-6, CAT score and smoking history (per year).
Conclusion
The study revealed that serum DcR3 level elevated with increasing severity of airflow limitation in male COPD patients, particularly in acute exacerbation phase. This increase was associated with a reduced quality of life and increased severity of hypoxia. These results suggest that DcR3 may be associated with the underlying pathophysiology of COPD in male patients.
