Regression models were used to assess the association between variables of interest and RA-ILD. Receiver operating characteristic curves were generated in BRASS to determine if a combination of clinical risk factors and autoantibodies can identify RA-ILD and if the addition of investigational biomarkers is informative. This combinatorial signature was subsequently tested in ACR.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Measurements and Main Results<\/jats:title>\n                    <jats:p>A total of 113 BRASS subjects with clinically indicated chest computed tomography scans (41% with a spectrum of clinically evident and subclinical RA-ILD) and 76 ACR subjects with research or clinical scans (51% with a spectrum of RA-ILD) were selected. A combination of age, sex, smoking, rheumatoid factor, and anticyclic citrullinated peptide antibodies was strongly associated with RA-ILD (areas under the curve, 0.88 for BRASS and 0.89 for ACR). Importantly, a combinatorial signature including matrix metalloproteinase 7, pulmonary and activation-regulated chemokine, and surfactant protein D significantly increased the areas under the curve to 0.97 (P\u2009=\u20090.002, BRASS) and 1.00 (P\u2009=\u20090.016, ACR). Similar trends were seen for both clinically evident and subclinical RA-ILD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Clinical risk factors and autoantibodies are strongly associated with the presence of clinically evident and subclinical RA-ILD on computed tomography scan in two independent RA cohorts. A biomarker signature composed of matrix metalloproteinase 7, pulmonary and activation-regulated chemokine, and surfactant protein D significantly strengthens this association. These findings may facilitate identification of RA-ILD at an earlier stage, potentially leading to decreased morbidity and mortality.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1164\/rccm.201411-1950oc","type":"journal-article","created":{"date-parts":[[2015,3,31]],"date-time":"2015-03-31T10:38:05Z","timestamp":1427798285000},"page":"1403-1412","source":"Crossref","is-referenced-by-count":209,"title":["Detection of Rheumatoid Arthritis\u2013Interstitial Lung Disease Is Enhanced by Serum Biomarkers"],"prefix":"10.1093","volume":"191","author":[{"given":"Tracy J.","family":"Doyle","sequence":"first","affiliation":[{"name":"Pulmonary and Critical Care Division, Brigham and Women\u2019s Hospital, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Avignat S.","family":"Patel","sequence":"additional","affiliation":[{"name":"Pulmonary and Critical Care Division, Brigham and Women\u2019s Hospital, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroto","family":"Hatabu","sequence":"additional","affiliation":[{"name":"Center for Pulmonary Functional Imaging"},{"name":"Department of Radiology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mizuki","family":"Nishino","sequence":"additional","affiliation":[{"name":"Center for Pulmonary Functional Imaging"},{"name":"Department of Radiology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guodong","family":"Wu","sequence":"additional","affiliation":[{"name":"Lovelace Respiratory Research Institute, Albuquerque, New Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan C.","family":"Osorio","sequence":"additional","affiliation":[{"name":"Pulmonary and Critical Care Division, Brigham and Women\u2019s Hospital, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria F.","family":"Golzarri","sequence":"additional","affiliation":[{"name":"Pulmonary and Critical Care Division, Brigham and Women\u2019s Hospital, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andres","family":"Traslosheros","sequence":"additional","affiliation":[{"name":"Pulmonary and Critical Care Division, Brigham and Women\u2019s Hospital, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah G.","family":"Chu","sequence":"additional","affiliation":[{"name":"Pulmonary and Critical Care Division, Brigham and Women\u2019s Hospital, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle L.","family":"Frits","sequence":"additional","affiliation":[{"name":"Division of Rheumatology, Immunology and Allergy, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christine K.","family":"Iannaccone","sequence":"additional","affiliation":[{"name":"Division of Rheumatology, Immunology and Allergy, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diane","family":"Koontz","sequence":"additional","affiliation":[{"name":"Division of Rheumatology and Clinical Immunology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carl","family":"Fuhrman","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Pittsburgh School of Medicine, Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael E.","family":"Weinblatt","sequence":"additional","affiliation":[{"name":"Division of Rheumatology, Immunology and Allergy, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Souheil Y.","family":"El-Chemaly","sequence":"additional","affiliation":[{"name":"Pulmonary and Critical Care Division, Brigham and Women\u2019s Hospital, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George R.","family":"Washko","sequence":"additional","affiliation":[{"name":"Pulmonary and Critical Care Division, Brigham and Women\u2019s Hospital, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary M.","family":"Hunninghake","sequence":"additional","affiliation":[{"name":"Pulmonary and Critical Care Division, Brigham and Women\u2019s Hospital, Harvard Medical School, Boston, Massachusetts"},{"name":"Channing Laboratory, Brigham and Women\u2019s Hospital, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Augustine M.
