Methods. We compared the characteristics of patients with newly diagnosed apparently idiopathic ILD with anti-SSA antibody [anti-SSA(+) group] and without anti-SSA antibody (control group). Results. Anti-SSA(+) patients (n = 15) more often had extra-respiratory signs (xerostomia and ocular dryness), auto-immune features, a CT scan pattern of non-specific interstitial pneumonia and more severe lung function alteration than controls (n = 30). Of patients who were anti-SSA(+), 2 met the criteria for SS and 13 (86%) of 15 met the criteria for the diagnosis of undifferentiated CTD. Conclusions. Our results suggest that identification of anti-SSA antibody in patients with early ILD can reveal a specific subgroup of patients with more ground glass opacity and more severe lung function impairment than those without anti-SSA antibody.
