OBJECTIVE: To compare long-term clinical, immunological, and radiographic outcomes between five sets of remission criteria (four clinical and one ultrasound (US)-based) in a cohort of RA patients in a clinical care setting. METHODS: RA patients in remission (DAS28-ESR <2.6) were selected. Hand US assessments were made, and serum levels of inflammation/angiogenesis biomarkers were determined at baseline. Changes in baseline treatment and radiographic progression, defined as the variation in the modified Sharp van der Heijde score (mSHS) at 5 years, were analyzed. Five concepts were used to define remission: DAS28-ESR<2.6, SDAI<3.3, CDAI<2.8, Boolean criteria and Power Doppler score (PD)=0. RESULTS: Eighty-seven patients with DAS28-ESR<2.6 were included. One-third fulfilled SDAI (33.3%), CDAI (31%), and Boolean (35.6%) remission criteria, and 25.3% had no PD signal in the US evaluation. 26 patients (29.9%) changed therapy, ranging from 13.6% (PD remission) to 33.3% (CDAI remission) (p=0.11). Serum levels of ANG (p=0.015) and TNFa (p=0.025) were significantly lower in patients with Boolean remission, whereas IL-18 levels were significantly lower in those with PD remission (p=0.049). Patients without PD in the US assessment had significantly-lower mSHS erosion progression (p=0.014) at 5 years. CONCLUSIONS: Patients with established RA in DAS28-ESR remission had comparable clinical and radiographic outcomes in SDAI, CDAI, and Boolean definitions in a clinical care setting. US remission remained the closest to structural damage abrogation. Key Points • This study provides real world data on long-term outcomes of five clinical and imaging remission criteria in rheumatoid arthritis. • DAS28-ESR remission criteria had comparable radiographic progression and clinical prognosis than more stringent criteria in clinical practice. • US-based remission was closest to structural damage abolishment.
