Impact of Capillaroscopy on the Management of Undifferentiated Connective Tissue Disease

Connective tissue diseases (CTD) are a group of diseases with diverse manifestations, most often multisystemic, which share an autoimmune etiology. They include Systemic lupus erythematosus (SLE), Systemic sclerosis (SSc), Sjögren's syndrome (SS), Inflammatory myopathies (IM) and Mixed connective tissue disease (MCTD). Many patients in rheumatology present signs and symptoms of CTD, but without meeting all the classification criteria for one of these diseases. These patients will generally receive a diagnosis of undifferentiated connective tissue disease (UCTD). It is increasingly suggested that there are two subgroups of patients with UCTD: one which will eventually evolve into a better characterized CTD (approximately 30% of patients at 5 years) and another with a more benign prognosis. The optimal management of patients with UCTD is not clearly established. Capillaroscopy is a diagnostic test used in the investigation of patients with CTD. It is a low-cost, non-invasive, rapid and specific test in the evaluation of this class of diseases. Its role is now well established in the diagnosis of SSc and in the investigation of Raynaud's phenomenon. In addition, capillaroscopy helps to identify patients suffering from CTD more quickly. Knowledge about the role of capillaroscopy in UCTD is more limited. It is established that a significant proportion of patients with UCTD present abnormalities on UCTD present non-specific abnormalities and 11% present a scleroderma pattern. In these patients, abnormal capillaroscopy seems to increase the risk of progressing to a better characterized CTD, notably SSc. However, although capillaroscopy is increasingly used in rheumatology in patients with CTD, more research is needed to clarify the role of this examination in UCTD. First, it is not established whether capillaroscopy should be performed in all patients with UCTD, nor when exactly it should be performed. There also remain questions about the impact of capillaroscopy on the prognosis and management of patients with this disease. To our knowledge, there is no prospective study that has addressed this question. The investigators hypothesize that in patients with UCTD, capillaroscopy compared to usual care makes it possible to increase the proportion of patients obtaining a diagnosis of better characterized CTD in the first six months of follow-up.

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.
