The goal of this multi-center prospective observational study is to develop knowledge on how to best personalize treatment and follow-up strategies for patients with RA in remission, with the intention to prevent relapse of disease activity and progression of joint damage and at the same time avoid the use of unnecessary treatment and health resources.
The investigators will perform an extensive evaluation of all patients who participated in the ARCTIC REWIND study 10 and 15 years after they achieved sustained remission and received different treatment strategies.
Rheumatoid Arthritis (RA) is a chronic inflammatory disease that affects 0.5 to 1.0% of the population. In case of ineffective treatment, the inflammation can lead to joint destruction and reduced physical function, as well as affecting internal organs. RA is associated with an increased risk of cardiovascular disease and osteoporosis.
The prognosis for RA has improved significantly over the past two decades, with effective treatment strategies and available drugs allowing a significant proportion of patients to achieve the treatment goal of remission (absence of signs of inflammation). RA has thus become a 'controllable' disease, and the large increase in the number of RA patients in remission leaves a need for improved understanding of how to best treat these patients.
A total of 259 RA patients in sustained remission were included in the ARCTIC REWIND trial. They were randomized to either tapering of DMARDs, or to continue stable DMARD medication, and followed for three years. The current study will provide a 10- and 15-year follow-up on the outcome of all these patients.
The results from the project will add knowledge about the long-term consequences of achieving sustained remission, as well as of experiencing a disease activity flare regarding DMARD use, joint damage progression, functional status and work productivity, and the study will provide novel data on cardiovascular health and other comorbidities in this patient group. Further, the patient perspective on flare will be explored. Such information will be valuable for patients and clinicians to improve shared decision on further treatment, and potentially allow more patients to reduce treatments in an evidence-based manner. Results from the study could influence approaches to the management of RA in the future, as selecting patients who can be switched to remote care (reduce the number of visits the patient has to attend physically).

| Measure | Description | Time Frame |
|---|---|---|
| Disease activity remission status | Remission status will be assessed according to e.g the disease activity score DAS, the Simplified Disease Activity Index (SDAI) and ACR/EULAR Boolean 2.0 remission. DAS includes the ritchie articular index, the swollen joint count (based on 44 joints), the ESR and the Patient's Global Assessment of disease activity on a VAS 0-100 mm (PGA). The following cut-points are used: High disease activity: DAS > 3.7; Moderate disease activity: 3.7 ≥ DAS>2.4; Low disease activity: 2.4 ≥ DAS ≥ 1.6; In remission: DAS < 1.6 The SDAI includes tender and swollen joints (of 28), PGA, PhGA and CRP. According to SDAI, the following cut-points are used: High disease activity: SDAI> 26.0; Moderate disease activity: 26.0 ≥ SDAI>11.0; Low disease activity: 11.0 ≥ SDAI > 3.3; In remission: SDAI ≤ 3.3 ACR/EULAR 2.0 remission is defined as the combination of tender joints ≤ 1, swollen joints ≤ 1, CRP ≤ 1 and patient global assessment ≤ 2 (on a scale 0-10). | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Disease Modifying Anti-Rheumatic Drug (DMARD)-free remission | The prevalence of DMARD-free remission | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Radiographic score (van der Heijde modified Sharp score (vdHSS) | Radiographs of hands and feet. The van der Heijde-modified Sharp scoring method will be used, which assesses erosions in 16 joints of each hand (range, 0-5 for each joint) and in 6 joints of each foot (range, 0-10 per joint) and joint space narrowing in 15 joints for each hand and in 6 joints for each foot (range, 0-4 per joint).This gives scores for erosions on a scale from 0 to 280 and joint space narrowing on a scale from 0 to168, thus the total van der Heijde-modified Sharp score ranges from 0 to 448, with higher scores indicating greater joint damage. | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Radiographic joint damage progression |

| Health-related quality of life | EuroQol-5 Dimensions three-level (EQ-5D-3L) is a utility instrument for measurement of health-related quality of life. It comprises the following five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, and extreme problems (labelled 1-3). They have no arithmetic properties and should not be used to derive a summary score. To derive the summary index score an appropriate value set is required, which provides values (weights) for each health state description according to the preferences of the general population of a country/region |

Radiographs of hands and feet. The van der Heijde-modified Sharp scoring method will be used, which assesses erosions in 16 joints of each hand (range, 0-5 for each joint) and in 6 joints of each foot (range, 0-10 per joint) and joint space narrowing in 15 joints for each hand and in 6 joints for each foot (range, 0-4 per joint).This gives scores for erosions on a scale from 0 to 280 and joint space narrowing on a scale from 0 to168, thus the total van der Heijde-modified Sharp score ranges from 0 to 448, with higher scores indicating greater joint damage.
The images will be compared to the last corresponding images undertaken in the ARCTIC REWIND trial.
Progression will be calculated as e.g. annual increase in van der Heijde modified Sharp score ≥ 1 unit.
| Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Disease activity composite measures | The following composite measures will be included: disease activity score (DAS), DAS based on 28 joint counts (DAS28), the simplified disease activity index (SDAI) and the clinical disease activity index (CDAI). These are based on tender and swollen joint counts, the PGA, acute phase reactants (except from CDAI), and, for SDAI and CDAI also the PhGA. DAS: High disease activity: DAS > 3.7; Moderate disease activity: 3.7 ≥ DAS>2.4; Low disease activity: 2.4 ≥ DAS ≥ 1.6; In remission: DAS < 1.6 DAS28: High disease activity: DAS28 > 5.1; Moderate disease activity: 5.1 ≥ DAS28>3.2; Low disease activity: 3.2 ≥ DAS28 ≥ 2.6; In remission: DAS28 < 2.6 CDAI: High disease activity: CDAI > 22.0; Moderate disease activity: 22.0 ≥ CDAI>10.0; Low disease activity: 10.0 ≥ CDAI > 2.8; In remission: CDAI ≤ 2.8 SDAI: High disease activity: SDAI> 26.0;Moderate disease activity: 26.0 ≥ SDAI>11.0; Low disease activity: 11.0 ≥ SDAI; In remission SDAI ≤ 3.3 | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Patient reported physical function | The Patient-Reported Outcomes Measurement Information (PROMIS) HAQ (Health Assessment Questionnaire ) 20-item short form will be used in this study. Each question has five response options, ranging in value from one to five. To find the total raw score, the sum of the values of the response to each question is calculated, giving a range in scores from 20 to 100 if all questions are answered. The total raw score should be translated into a T-score for each participant (either by standardized conversion tables or using item-level calibrations), which rescales the raw score into a standardized score with a mean of 50 and a standard deviation (SD) of 10. Therefore, a person with a T-score of 40 is one SD worse than average. | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Patient global assessment of disease activity | 0-100 visual analogue scale (VAS), with higher scores Indicating more disease activity | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Physician global assessment of disease activity | 0-100 visual analogue scale (VAS), with higher scores Indicating more disease activity | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Ultrasound inflammation | Ultrasound joint inflammation will be assessed by use of a validated 0-3 semi-quantitative scoring system for power Doppler and grey scale with an ultrasound atlas as reference.

| Medication use | Record of disease modifying antirheumatic drugs including corticosteroids | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Physical and mental health | This will be assessed by The 36-item Short Form Health Survey (SF-36). The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability. The eight sections are: vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, mental health or emotional wellbeing | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Patient reported impact of disease | Assessed by the Rheumatoid Arthritis Impact of Disease (RAID) score which is a patient-derived composite response index for use in clinical trials in RA. It includes seven domains which are scored between 0 and 10. The domains are given the following relative weights: pain (21%), functional disability (16%), fatigue (15%), emotional well-being (12%), sleep (12%), coping (12%) and physical well-being (12%). The range of the final RAID value is 0-10 where higher scores indicate worse status. | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Work performance and status | Work Productivity and Activity Impairment Questionnaire: WPAI:RA. This is a questionnaire that quantifies health-related work productivity loss for those employed. Work time missed (absentism) and reduced on-the-job effectiveness are expressed in percentages. Overall work productivity loss (abstentism and presentism combined) is also expressed in percentages. | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Presence of cardiovascular disease and CVD risk | assessed by Systematic Coronary Risk Evaluation 2 (SCORE2), carotid intima-media thickness and plaques, and echocardiography | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |

| C-reactive protein (CRP) | Blood test | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Patients reported flare | The Outcome Measures in Rheumatology (OMERACT) preliminary Rheumatoid Arthritis Flare Questionnaire version 2.1 will be used. The questionnaire includes information about variables deemed to be of relevance by both patients and health care professionals to describe and define RA flare. It assesses severity and duration of flare, self-management strategies related to flare, pain, function, fatigue, stiffness, participation, coping, and patients' self-assessment of joint tenderness and swelling. Patients who classifies themselves as flaring rates the severity on a 11-point Numerical Rating Scale (0-10), the higher score the worse. | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Registration of comorbidities | Questionnaire about comorbidities, including, but not limited to, cardiovascular/cerebrovascular disease, respiratory disease, diabetes mellitus, hypertension requiring treatment, cancer, fibromyalgia, osteoporosis, depression requiring treatment, joint replacements, hip fractures, and abdominal perforations. | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Fatigue | Fatigue is self-reported with use of a visual analogue scale that ranges from 0 to 100 mm, with higher scores indicating more severe fatigue. | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
| Joint pain | joint pain is self-reported with use of a visual analogue scale that ranges from 0 to 100 mm, with higher scores indicating more severe joint pain | Assessed at the visit 10- and 15-year after the initial inclusion into the ARCTIC REWIND trial |
