Collagen-vascular disorders (CVD) are commonly associated with chronic interstitial lung disease. Clinicopathologic observations suggest that inflammatory process of the lower respiratory tract may appear prior to fibrosis. Subclinical pulmonary involvement, as assessed by bronchoalveolar lavage (BAL) was evaluated in 61 patients with various CVD but free of clinical pulmonary symptoms and with normal chest roentgenograms. Eight of 61 had abnormal pulmonary function tests (PFT) at entry to the… CONTINUE READING
