Hypothesis
Are soluble TREM-1 levels elevated in patients with stable chronic obstructive pulmonary disease (COPD) compared to healthy individuals?
Conclusion
Serum concentrations of soluble TREM-1 are increased in patients with COPD and correlate with disease severity.
Supporting Evidence
- Healthy subjects had low sTREM-1 levels (median 0.25 ng/mL).
- COPD patients had significantly higher sTREM-1 levels (median 11.68 ng/mL).
- Serum sTREM-1 levels correlated negatively with lung function impairment.
Takeaway
This study found that people with COPD have higher levels of a protein called sTREM-1 in their blood, which might help show how severe their disease is.
Methodology
The study used a newly developed ELISA to measure sTREM-1 levels in serum from COPD patients and healthy controls.
Limitations
The study had a small sample size and was limited to stable COPD patients.
Participant Demographics
12 COPD patients (5 female, 7 male) and 10 healthy controls (4 female, 6 male), with an average age of 56 for COPD patients and 51 for controls.
