question:
Question: Are bronchoalveolar lavage cellular profiles in patients with systemic sclerosis-associated interstitial lung disease predictive of disease progression?
Answer: BAL findings provide only limited prognostic information in SSc-ILD. Neutrophilia on BAL is linked to early mortality, but BAL findings are not linked to long-term survival or the rapidity of progression of lung disease. The usefulness of BAL to define alveolitis in SSc is questionable.
answer:
no
