AbstractA 71-year-old woman sought treatment for a nonproductive cough. The patient had experienced no episodes of hemoptysis or shortness of breath. Her illness history included lumbago and dry mouth. The patient did not smoke and had no significant family medical history or medication use. She had no allergies to any food or drugs. Blood test results, including a CBC count, biochemical examination, and coagulation, were unremarkable. Autoantibody screening revealed positive antinuclear antibody findings with a titer of speckled and nucleolar, and anti-Ro/SSA antibodies were elevated at 240 U/mL (normal range, < 7.0 U/mL). Chest CT scan imaging showed a slight infiltrative shadow of the bilateral lower lobes. Because the patient was suspected to have interstitial pneumonia resulting from Sjögren disease, we decided to perform fiber optic bronchoscopy with BAL for evaluation of interstitial lung disease.Copyright © 2023 American College of Chest Physicians.
