Abstract
Anti-PL-7 is an anti-tRNA synthetase antibody, and interstitial lung disease (ILD) is the most frequent complication of anti-PL-7-associated antisynthetase syndrome. However, the features of ILD have not been fully elucidated. The present study retrospectively compares 7 and 15 patients who were positive for anti-PL-7 and anti-Jo-1 antibodies, respectively. The features of ILD did not significantly differ between the two groups, but the ratio of lymphocytes in bronchoalveolar lavage fluid was higher in the Jo-1 than in the PL-7 group. High-resolution computed tomography revealed nonspecific interstitial pneumonia in all patients in the PL-7 group and organizing pneumonia in four of the 15 patients in the Jo-1 group. These findings suggest that pulmonary complications slightly differ between patients expressing anti-PL-7 and anti-Jo-1 antibodies. Further studies are required to clarify the features of ILD associated with PL-7.Entities:
