ABATACEPT IN RHEUMATOID ARTHRITIS WITH INTERSTITIAL LUNG DISEASE. A MULTICENTRE STUDY OF 181 PATIENTS

Background: Interstitial Lung Disease (ILD) is a severe extraarticular manifestation of rheumatoid arthritis (RA). Objectives: Our aim was to assess the efficacy of abatacept (ABA) in RA patients with ILD. Methods: Retrospective multicenter study of RA patients with ILD treated with ABA. ILD was diagnosed by HRCT. We have analyzed the following variables: a) 1-point change the Modified Medical Research Council (MMRC); b) FVC improvement ≥10%; and improvement ≥10% in DLCO; c) radiological improvement in HRCT scan, d) changes in DAS28 score. Values were compared with baseline e) prednisone doses Results: We studied 181 patients (94women/87 men) with ILD associated to RA. The follow-up was 12.1[6.2-24.1] months. The mean age was 64.54 ± 9.7 years. The median to progression of ILD was 12 [3-43.75] months. 81 patients were treated in monotherapy, 100 patients in combination therapy. The most frequent pattern was UIP 45,3%. The most of patients who did not have dyspnea remained asymptomatic. See results in Figure1 . DAS28 also improved. We appreciate a decrease in the dose of prednisone compared to the initial dose. Conclusion: ABA seems to be effective. However, should be verified in prospective and randomized studies.
