ABSTRACT
Background:
Interstitial Lung Disease (ILD) is the most common lung involvement in rheumatoid arthritis (RA) and leads to increased morbidity and mortality. Some retrospective observational studies suggest that abatacept (ABT) could be effective and safety, although there are no clinical trials and prospectively collected data are scarce.Objectives:
To evaluate prospective the effectiveness and safety of ABT in patients with ILD associated RA (ILD-RA).Methods:
Design and Protocol We performed a multicenter, prospective, observational study of patients with interstitial lung disease secondary to rheumatoid arthritis (ILD-RA) receiving ABT between 2015 and 2021. The patients were assessed using high-resolution computed tomography and lung function tests at the beginning of treatment (V0), at 12 months (V12), and at the end of follow-up in 2021 (fV). The study was approved by the Ethics Committee (Code 1719-N-15). Main variable effectiveness of ABT according to evolution of ILD at the end of follow-up (1) improvement (ie improvement of FVC ≥10% or DLCO ≥15% and no radiological progression), (2) no progression (stabilization or improvement in FVC ≤ 10% or DLCO <15% and no radiological progression), (3) progression (worsening of FVC >10% or DLCO >15% and radiological progression) or (4) death. Other variables clinical and analytical characteristics, treatments and safety (infections, hospitalization and mortality). Statisticalanalysis:
Cox regression analysis to identify factors associated with worsening of ILD-RA treated with ABT.Results:
Thirty-eight ILD-RA patients started ABT treatment during prospective follow-up. A total of 22/38 (57.9%) were men and the mean (SD) age was 66.1 (9.1) years. The mean (SD) evolution of ILD was 43.9 (30.0) months and the median (IQR) time with ABT was 17.0 (12.1-34.8) months. The baseline clini-cal-epidemiological characteristics and pulmonary progression of the patients are shown in Table 1. At the end of follow-up (fV) 28/38 (73.6%) had improvement/stabilization and 7/38 (18.4%) progressed and 3/38 (7.8%) of them died (COVID-19 pneumonia, respiratory infection and ILD progression, respectively). There were no signifcant differences in FVC (75.3 [8.7] vs 77.7 [14.6];p=0.775) or in FEV1 (83.9 [10.7] vs 84.7 [13.2];p=0.416) nor in the DLCO (61.0 [17.4] vs 60.7 [15.2];p=0.789) at the end of follow-up. There was a greater numberwith improvement/stabilization among the patients who were in combination with Methotrexate compared to those who were in monotherapy (83.3% vs 39.1%;p=0.046). The baseline variables that were independently associated with progression-mortality of ILD-RA in fV were baseline FVC (OR [95% CI], 0.895 [0.805-0.996];p=0.042) and duration of ILD-RA (OR [95% CI], 1.204 [1.148-2.112;p=0.046]). Two patients discontinued ABT during follow-up due to insufficient joint and pulmonary response.Conclusion:
More than half of the patients with ILD-RA treated with ABT manage to stabilize or improve their lung disease after a median follow-up of 17 months. Patients who worsen or die have lower baseline FVC values and ILD-RA with a longer evolution time.
