Design outcomes

Primary

Measure	Time frame
1. Level of IL-6 in BAL fluid 2. Inflammatory, fibroproliferative and osteogenic cytokines in BAL fluids 3. Degree of proinflammatory, profibrotic and osteogenic differentiation of fibroblasts isolated from lung BAL and bronchial biopsies 4. Degree of tissue markers involved in the calcification process and SSc progression in bronchial biopsies 5. Degree of other serum markers of the calcification process: T50, calcium, phosphorus, parathormone, fetuin-A, Fibroblast Growth Factor-23 (FGF23), aKlotho; 6. Degree and extent of pulmonary involvement of ILD and pulmonary ossifications by lung function (FVC, FEV1, DLCO), and HRCT 7. Degree of vasculopathy by: noninvasive nailfold capillary microscopy; arterial stiffness; digital artery involvement as assessed with ultrasound; 8. Clinical parameters on SSc organ and degree of skin and additional organ involvement, SSc-antibody profile, medication use, and comorbidities.	—
