“Identifying Unique Pathogenic Macrophages in Systemic Sclerosis-ILD”
Alveolar macrophages isolated from bronchoalveolar lavage (BAL) fluid from SSc patients with clinically significant lung fibrosis will be studied at baseline and at 6 months after enrollment to assess longitudinally the presence and persistence of an emergent, pro-fibrotic alveolar macrophage population, using single cell RNA-Seq technology to measure the individual transcriptome from each cell.

Diagnostic Test - Bronchoscopy with lavage
During an elective bronchoscopy procedure, the bronchoscope will be wedged into an affected lung segment guided by CT scanning. When involved an anterior segment will be used to maximize return. After wedging the bronchoscope, 120ml of sterile 0.09% normal saline will be instilled. Up to 40-60 mL of BAL fluid will be obtained for analysis during each sampling.
