Hypothesis
Endothelin-1 is involved in the inflammatory process of pulmonary vasculitis in Behçet's disease.
Conclusion
Increased endothelin-1 production from alveolar macrophages is associated with pulmonary manifestations in Behçet's disease.
Supporting Evidence
- ET-1 levels in BALF were significantly higher in BD patients than in controls.
- ET-1 levels correlated with the number of alveolar macrophages.
- All alveolar macrophages in BD patients were immunopositive for ET-1.
Takeaway
This study found that patients with Behçet's disease have higher levels of a substance called endothelin-1 in their lungs, which might be linked to their lung problems.
Methodology
The study measured endothelin-1 concentrations in bronchoalveolar lavage fluid from 18 patients with Behçet's disease and 12 control subjects.
Participant Demographics
18 active Behçet's disease patients (12 males, 6 females; mean age 49.8 years) and 12 control subjects (5 males, 7 females; mean age 46.2 years).
