Assessing Central Aspects of Pain

BACKGROUND: Chronic pain continues for more than 12 weeks despite medication or treatment. Chronic pain is the main symptom of muscle and joint problems, rarely explained by damage to the muscle and joints alone. Activity in the central nervous system (CNS; nerves, spinal cord, and brain) pathways governs our ability to describe pain intensity and our emotional response to pain. Musculoskeletal conditions (e.g., inflammatory arthritis, osteoarthritis, low back pain, fibromyalgia) share altered CNS pathways, acknowledged by recent classifications of 'primary' and 'nociplastic' pain. Clinically useful tools to diagnose and measure activity and reveal abnormalities in these CNS pathways are needed to improve clinical decisions and accelerate new treatment development. Laboratory pain sensitivity testing and brain imaging confirm the CNS as a primary contributor to pain. These assessments are less acceptable or unfeasible for clinical practice. Simpler clinical pain sensitivity assessments are being developed. The investigators simple Central Aspects of Pain (CAP) questionnaire detects some people with pain sensitivity and knee, rheumatoid arthritis or low back pain. Combining the CAP questionnaire reflecting emotional processing and simpler pain sensitivity assessment, combining two different dimensions should be better than either approach alone. PURPOSE: To optimise diagnosis and measurement of CNS as the primary contribution to chronic musculoskeletal pain by using the CAP questionnaire and simpler pain sensitivity assessments to ensure timely, effective diagnosis and treatment. OBJECTIVES: 1. Assess the ease, ability and performance of the combined CAP questionnaire and simpler pain sensitivity assessments to identify CNS as the primary contributor to chronic pain across musculoskeletal conditions. 2\. Use the CAP questionnaire alone or with substitute measures of activity in CNS pathways, demographic, and clinical variables to indicate pain levels at six and twelve weeks. 3\. Understand the relationship between CAP and simpler pain sensitivity assessment with laboratory pain sensitivity assessments as a tool to inform the current CNS activity contributing to pain. 4\. Evaluate associations between the CAP questionnaire and simpler pain sensitivity assessments with patient outcomes.

Understanding of Rare Inflammatory Arthritis in Comparison to Classical Inflammatory Arthritis : Tissular Observations and Immune Infiltrate Characterization : the UTOPIC Project

The pathophysiology of certain inflammatory arthritides remains poorly understood, particularly when associated with rare systemic autoimmune diseases such as systemic sclerosis (SSc), or when emerging in the context of immune-related adverse events from cancer immunotherapies. These immunotherapy-induced arthritides represent a new and increasingly encountered clinical entity in rheumatology. A deeper understanding of the mechanisms underlying joint inflammation in these settings is essential for identifying specific therapeutic targets, especially given the limitations of current treatment options and the risks associated with broad immunosuppressive strategies such as prolonged corticosteroid use, which may impair anti-tumor immune responses. Synovial biopsy analysis provides a powerful tool for dissecting the cellular and molecular components of joint inflammation, including immune cell infiltration, cytokine profiles, and cell-cell interactions. Advances in high-dimensional techniques such as multiplex immunofluorescence and mass cytometry now allow for the identification and spatial localization of numerous protein markers at the subcellular level. Additionally, spatial transcriptomics offers complementary insight into gene expression profiles within the tissue microenvironment, providing a comprehensive understanding of inflammatory processes. The investigators propose a prospective, proof-of-concept study to characterize and compare rare and emerging inflammatory arthritides-including those linked to SSc and immunotherapy-related immune toxicity-with classical inflammatory rheumatic diseases such as rheumatoid arthritis (RA), psoriatic arthritis (PsA), spondyloarthritis (SpA), polymyalgia rheumatica (PMR), and reactive arthritis. Through detailed immunological and molecular profiling, this study aims to identify disease-specific signatures and novel therapeutic targets. These findings could pave the way for precision medicine approaches and inform the development of targeted therapies in both rare and common forms of inflammatory arthritis.

Palliative and Supportive Care to Help People With Arthritis to Live Well (ENRICH)

Palliative Care (PC) focuses on maximising quality of life and care for patients and their families in the last 1000 days of life. Supportive Care (SC) is provided earlier in life for people with a long-term health condition. People living with inflammatory arthritis, (such as rheumatoid arthritis) can experience ongoing pain, stiffness, limitations in their joints, and intrusive fatigue. This impacts daily living activities and emotional well-being. People with inflammatory arthritis would value support to manage symptoms across the course of their disease. They would like PC healthcare professionals (HCPs) to understand their conditions better, so they can live well to the end of their lives. Aims: The investigators will explore the potential role of Palliative and Supportive Care (PSC) for people with inflammatory arthritis. The investigators will describe any unmet patient need. The investigators will develop clinical and research recommendations to help people with inflammatory arthritis live well over the course of their disease. Plan: The investigators research will be conducted in three studies: Study 1: The investigators will conduct 1:1 online interviews with people with inflammatory arthritis to understand how PSC is perceived by them, and what their views are on how PSC may support them to live well. Study 2: The investigators will send an online survey to Rheumatologists, Primary Care, Community and PC HCPs, to understand: * if and how they work together currently; * their views on the role of PSC supporting people with inflammatory arthritis to live well. Study 3: The investigators will conduct online focus groups with volunteers from Studies 1 and 2, representatives from relevant national charities/organisations, and people who commission health services. Together the group will discuss the research findings and agree: * what the gap in patient care is; * recommendations for future clinical practice and research; * the key areas of importance for patients which should be measured in future work

Early Adalimumab Induction for Immune Checkpoint Inhibitor Associated Inflammatory Arthritis

This study will examine the effectiveness of administering adalimumab as a treatment for patients in the early stages of steroid-dependent immune checkpoint Inhibitor associated inflammatory arthritis (ir-IA). Adalimumab (ADA) is a TNF inhibitor (TNFi) that is well established as a standard of care treatment for numerous types of inflammatory arthritis. It is hoped that adalimumab at the early stages of the ir-IA will reduce the symptoms and therefore reduce the need for steroids. This study is a pragmatic randomized clinical trial. Patients will be randomized 1:1 to each treatment group. To evaluate the steroid sparing effect of early induction six doses of Adalimumab will be administered to patients in the study treatment arm as compared to the usual standard of care of a predefined corticosteroid regimen and taper at 12 weeks administered in the control group.

DEXA Bone Density Analysis of the CoreHip® Prosthesis System

The goal of this interventional post-market follow-up study is to evaluate radiological changes in the diaphyseal bone density (Gruen Zones 3 and 4) within 24 months postoperative in patients treated with CoreHip® primary cementless stem. The DEXA bone density analysis is used.

Validation of Hemoglobin A1c in Patients With Inflammatory Arthritis Treated With Sulfasalazine

The purpose of this study is to examine whether the blood test Hemoglobin A1c (HbA1c) gives an accurate picture of blood glucose levels in patients with inflammatory arthritis who are treated with sulfasalazine. HbA1c is widely used to diagnose and monitor diabetes, but sulfasalazine can shorten red blood cell lifespan and thereby lower HbA1c values independently of actual glucose levels. This may lead to underdiagnosis of diabetes in patients who develop diabetes during sulfasalazine treatment, and to undertreatment in patients with known diabetes due to falsely reassuring HbA1c values. The study aims to answer two main questions: 1. How many patients treated with sulfasalazine have undiagnosed diabetes despite having HbA1c values below the diagnostic threshold? 2. Does HbA1c underestimate actual glucose levels when compared with continuous glucose monitoring (CGM) in patients with sulfasalazine-treated inflammatory arthritis, both in those with known diabetes and those that are not diagnosed with diabetes but have borderline HbA1c values (≥ 38 mmol/mol)?

Effect of a Self-Management Intervention for Patients Newly Diagnosed With Inflammatory Arthritis: The NISMA Trial

Background: In patients newly diagnosed with inflammatory arthritis, a self-management intervention is anticipated to enhance self-management skills, thereby improving patient function, well-being, and survival. The primary objective of the trial is to investigate the short-term efficacy of the NISMA intervention and usual care, compared to usual care alone (control group), on self-management skills and techniques in patients newly diagnosed with inflammatory arthritis. Method: This study aims to test the efficacy of the "Newly diagnosed with Inflammatory arthritis - a Self-MAnagement intervention" (NISMA) through a multicenter pragmatic randomized controlled trial (RCT). The trial will involve 130 patients newly diagnosed with IA from three Danish hospitals. Participants will be randomly assigned to either the NISMA intervention group or a control group receiving usual care. The NISMA intervention includes three mandatory individual sessions with a nurse, supplemented by two optional group sessions over 12 months. Primary outcomes will be measured using the Health Education Impact Questionnaire (heiQ), focusing on the "skill and technique acquisition" domain. Secondary outcomes include other heiQ domains, quality of life, loneliness, physical function, pain intensity, pain, self-efficacy, anxiety and depression, fatigue, patient global assessment, disease activity, and medication adherence. Data will be collected at baseline, 12 months, and 18 months post-baseline. Discussion: This RCT will provide essential insights into the effectiveness of a targeted self-management intervention for patients newly diagnosed with IA. The NISMA intervention, developed following the Medical Research Council Framework for complex interventions, aims to improve self-management skills and overall QoL. By addressing the unique challenges faced by newly diagnosed patients, this study seeks to enhance the initial management of IA, aligning with the European Alliance of Associations for Rheumatology (EULAR) recommendations for self-management support. If successful, the NISMA intervention could represent a significant advancement in the non-pharmacological management of IA, offering a comprehensive, patient-centered approach that addresses both physical and psychological needs.

Rotator Cuff Sparing Total Arthroplasty

Design: Prospective, randomized clinical trial, of 120 patients requiring a total shoulder replacement (TSR). Purpose: To collect and evaluate long-term clinical data on patients whose total shoulder replacement (TSR) is performed using the traditional surgical approach (called the subscapularis release approach) as compared to patients who have a TSR procedure done using a newer surgical approach (called the rotator cuff sparing approach).

3D DL Ozteo in the Detection of Osseous Changes in Patients With Inflammatory Arthritis

This project intends to explore and validate the utility of new MRI pulse sequence, 3D DL oZTEo, in the detection of osseous erosions of the hand in patients with inflammatory arthritis. The detection of osseous structural changes, such as erosive disease, is routinely assessed in patients with rheumatic conditions such as rheumatoid arthritis, as it alters clinical management, and in some cases assists in diagnosis. Currently, this is most often assessed with radiography and conventional MRI.

The RheumSafer Study: Improving Medication Appropriateness in People With Rheumatic Conditions

People with rheumatic conditions often take many medications, but more pills can increase the risk of side effects, especially in older adults. Some drugs (such as those intended to help pain or sleep) may cause more harm than good in the long term, and others may simply be no longer needed. These are known as 'potentially inappropriate medications' (PIMs). This quality improvement study focuses on people with rheumatic conditions aged 60 and over who take 5 or more daily medications. The goal of the study is to learn if a publicly available physician tool, MedSafer, combined with educational brochures (for patients), can help to reduce PIMs in this group. Researchers will follow participants during usual rheumatic disease care. They will compare the rate of PIM deprescribing (stopping medications or reducing the dose) before and after the introduction of the following 'bundle': * MedSafer reports provided to treating physicians * EMPOWER consumer brochures provided to patients Participants will be followed over 4 study visits (for 14-18 months) during which researchers will collect information on medication changes and serious adverse events (emergency visits or hospitalizations) and will complete questionnaires measuring quality of life.

Rheumatology-based Adaptive Intervention for Social Determinants and Health Equity

Social determinants of health (SDoH), defined by the World Health Organization as "the conditions in which people are born, grow, work, live and age and the wider set of forces and systems shaping the conditions of daily life" are estimated to be responsible for nearly 90 percent of a person's health outcomes. SDoH are key contributors to racial, ethnic and socioeconomic disparities in care healthcare access and health outcomes. The goal of this clinical trial is to identify patients with inflammatory arthritis or with a systemic rheumatic condition with arthritis who may respond to the simplest and least expensive intervention to address their SDoH-related needs- a tailored list of resources, those who benefit from a community-based resource specialist to help address specific needs, and those who require a nurse-trained navigator to help both coordinate the services provided by the community-based specialist, and their medical and mental health care and needs. The main questions the clinical trial aims to answer are: 1. To test the efficacy of a rheumatology clinic-based nurse navigator and community resource specialist to reduce appointment no-shows and same-day cancellations in patients with systemic rheumatic conditions with arthritis. 2. To examine the cost-effectiveness of each of the different study interventions for individuals with systemic rheumatic conditions with arthritis with SDoH-related needs using questionnaires and cost-related care metrics. Participants will be randomly assigned to 1 of 3 arms. In Arm 1, patients will receive a cultivated list of resources related to the needs that patients indicate on the social determinants of health questionnaire. Arm 1 is the control arm which receives the current standard of care. In Arm 2, patients will receive the assistance of a community resource specialist (CRS) - an individual without formal medical training with community-based expertise. In Arm 3, patients will receive the assistance of a nurse patient navigator with additional systemic rheumatic condition-specific training who will work with the CRS. After 6 months, patients who do not respond to Arm 1 will move to Arm 2. Patients who do not respond to Arm 2, will move to Arm 3. Patients who do not respond to Arm 3 will remain in Arm 3. Patients who respond to any arm will graduate the program at 6 months. The patients who do not respond be in their new arm for 6 months. At 12 months, all patients remaining in the study will graduate.

The purpose of this study is to assess the long-term safety and performance of the LEGION Medial Stabilized insert and to generate clinical evidence to support and maintain product registration in global markets.

COMFI - a COMbined Fatigue Intervention

Background: Inflammatory arthritis (IA) encompasses autoimmune rheumatic diseases, such as rheumatoid arthritis, psoriatic arthritis, and axial spondyloarthritis. Fatigue is highly prevalent in people with IA with 41-57% suffering from severe fatigue. Patients describe fatigue as overwhelming, unpredictable, challenging to manage, and affecting all areas of everyday life, including the ability to work. Studies have shown that interventions with physical activity or a cognitive behavioral approach can significantly reduce fatigue severity and/or impact in people with IA compared to usual care. To date, no studies have investigated the combined effect of CBA and PA on fatigue severity and impact in patients with IA. Therefore, the goal of this study is to test the feasibility of a newly developed fatigue intervention that combines a cognitive behavioral approach and physical activity (COMFI) in patients with inflammatory arthritis, who experience fatigue as a challenge in their everyday lives in Denmark and Sweden. The intervention will be tested in 4 groups (2 in Denmark and 2 in Sweden), and the participants will participate in 7 group sessions and 2 focusgroups interview in the evaluation. The primary outcome for the participants is fatigue, measured through patient-reported outcomes at baseline, 3, 6, and 12 months after baseline. This study will show if the intervention is feasible in practice and meaningful for the participants.

Personalized Outreach for Equitable Treatment in Rheumatology

The primary goal of this study is to determine whether providing patient honoraria and/or outreach services can improve the attendance rate of appointments at an inner city rheumatology clinic in Vancouver, British Columbia. The main question it aims to answer are: * Does providing a financial honorarium ($20 for each follow-up appointment with completed bloodwork) improve attendance rate at an inner city rheumatology clinic? * Does providing a personalized outreach service for rheumatic diseases improve attendance rate at an inner city rheumatology clinic? The researchers will compare providing patient honoraria to providing both honoraria and outreach services, and compare each of these to the regular appointment schedule without honoraria or outreach. Participants will: * Undergo randomization to receive honoraria or honoraria and outreach services together * Complete surveys about their health and understanding of their rheumatic disease at baseline, 3-month, and 6-month intervals * Visit the clinic every month for check-ups and monitoring bloodwork if they are started on immunosuppressants for their condition

The CCP Study: Coordinated Programme to Prevent Arthritis - Can We Identify Arthritis at a Pre-clinical Stage ?

This is a 12-month, prospective, observational cohort trial involving Primary Care Trusts (PCTs) wishing to take part in the study and the Early Arthritis Clinic (Anti-CCP sub-clinic) at Chapel Allerton Hospital. The approximate duration of subject participation will be 12 months and the approximate total duration of the study will be 10 years. Patients who have not developed inflammatory arthritis within the 12 month period will have the opportunity to continue follow up within the clinic on an annual basis with additional visits as clinically indicated until the development of IA.

Prognostic Evaluation of Inflammatory Polyarthritis of Recent Onset

Inflammatory joint diseases are major causes of invalidity and morbidity. Rheumatoid arthritis (RA), the most frequent of chronic arthritides, affects close to 1% of the Canadian population. Direct and indirect costs of RA represent close to 1% of the gross national product. Recent evidence suggest that initiation of early (e.g., during the first 3-12 months of disease) aggressive treatment decreases both mortality and long term invalidity in RA and other chronic arthritides. However, a significant proportion of patients with early polyarthritis (EPA) have a benign evolution, even if they fulfill criteria for RA. On the contrary, most patients whose arthritis persist for more than 12 months have a progressive and destructive disease. Currently available clinical, serological and genetic markers of severity in arthritic patients perform poorly in EPA patients to identify those patients whose arthritis is likely to persist and thus who deserve an aggressive treatment. The Investigators propose a prospective and longitudinal study to define the contribution of detection of rheumatoid arthritis-specific autoantibodies (RASA), either alone or in combination with other markers of severity, in the prognostic evaluation of patients presenting with EPA. Availability of such an effective serological tool to establish prognosis in individual patients would improve therapeutic decisions in clinical practice. The same prognostic tools would represent very powerful instruments to subset patients into more homogeneous groups in clinical trials, increasing their power.

This will be done by analysis of standard scoring systems, radiographs and adverse event records. Data will be used to monitor pain, mobility and survivorship, and to confirm the safety and efficacy of the Continuum Ceramic-on-Ceramic Bearing System.

Automated Arthritis Detection Using Artificial Intelligence on Smartphone Photographs

The investigators are testing the ability of convolutional neural networks (CNNs), that is artificial intelligence, on smartphone photographs in detecting inflammatory arthritis. This promises to be an efficient, accurate, and non-invasive diagnostic tool that will significantly improve early detection and management of inflammatory arthritis.

The Relationship Between Inflammatory ARTritis and CArdiac DIseAse

The goal of this prospective cohort study is to investigate cardiac comorbidity in a random sample of approximately 1200 patients from a population of outpatients with rheumatoid arthritis and axial spondyloarthritis referred to collectively as inflammatory arthritis (IA). The main questions it aims to answer are: * Using conventional echocardiography, the investigators aim to determine the prevalence of overt and asymptomatic cardiac dysfunction in a large random sample of outpatients with IA. Cardiac dysfunction will be evaluated by echocardiography and cardiac biomarkers (NT-pro-BNP, hs-TNT and hs-CRP). * In patients without known heart disease: Using 2, 5 and 10 year follow-up, the investigators aim to examine if advanced echocardiography can be used to detect early signs of heart disease by investigating the clinical significance of adding deformation measures - alone and in combination with selected biomarkers - to conventional risk factors in the cardiac risk assessment of patients with IA Participants will undergo an echocardiographic examination in combination with a general health assessment including obtainment of cardiac biomarkers and a electrocardiogram. Using advanced echocardiography - Tissue Doppler Imaging, 2- dimensional speckle tracking echocardiography, 3D-echocardiography and 3-dimensional speckle tracking echocardiography - the investigators also aim to compare myocardial deformation parameters of patients with IA to a gender and age matched control group without IA from the Copenhagen City Heart Study.
