This study involves blood tests, sputum collection, physical exams, and questionnaires; it may also involve pulmonary function tests (PFTs) and a high-resolution computed tomography (HRCT) scan of your lungs. PFTs involve breathing into a tube to determine any lung abnormalities while HRCTs are done to scan your lungs to find any traces of inflammation. To collect the sputum, we will have you inhale aerosolized salt-water for 15 minutes to loosen up mucus in your airways, then have you cough your sputum into a collection cup..




You qualify to participate in SAPPHIRE if you have a diagnosis of RA with or without ILD.
