ABSTRACT
OBJECTIVES:
To compare the features of difficult-to-treat rheumatoid arthritis (D2TRA) patients using two different definitions according to the previous failure of targeted therapies.METHODS:
We stratified consecutive RA patients treated at Cochin Hospital into two groups, a D2TRA group and a non-D2TRA group, according to two definitions of D2TRA. Both definitions defined D2TRA as RAs failing at least two targeted therapies, with a different mechanism of action for the EULAR-D2TRA definition or without prejudging the mechanism of action and for the Alternative D2TRA definition.RESULTS:
We included 320 consecutive RA patients. We identified 76 EULAR-D2TRA and 244 non-DTRA patients, and 120 Alternative D2TRA and 200 non-DTRA patients. Compared with non-D2TRA, D2TRA patients from both definitions were more likely to have lower socioeconomic level, positive rheumatoid factor, interstitial lung disease, higher DAS28-CRP and were more likely to respond to rituximab and Janus kinase inhibitors. Although EULAR and Alternative D2TRA patients displayed similar clinical and biological features, they were characterized by different therapeutic profiles. We observed fewer patients receiving methotrexate in the Alternative D2TRA group (53% vs 64%, P = 0.046). Patients with Alternative D2TRA not fulfilling the EULAR definition (n = 44) had all received two successive first-line TNF inhibitors, a monoclonal antibody and a soluble receptor, and were comparable to EULAR-D2TRA patients with regards to all other characteristics.CONCLUSION:
Low socioeconomic status, diabetes, interstitial lung disease and absence of combination with methotrexate allow identification of D2TRA. In addition, the inclusion as 'early-D2TRA' of patients failing two TNF inhibitors in the EULAR definition of D2TRA would facilitate the rapid identification of D2TRA patients.Palavras-chave
