Filter by:This project aims to study systemic sclerosis and find a serum marker of its cutaneous involvement. Systemic sclerosis (SSc) is a rare immune disease that is part of connectivitis and is characterized by fibrosis and vasculopathy. Multiple visceral lesions involving these two processes make up the severity of this disease. Its dermatological involvement is a fundamental clinical element. Systemic sclerosis is mainly divided into two subtypes, depending on the extent of dermatological involvement: limited and diffuse systemic sclerosis. These also differ in certain autoantibody profiles and clinical features. Nevertheless, it is still necessary to determine certain criteria, markers, making it possible to distinguish at an early stage the presence of limited or diffuse systemic sclerosis. The latter being characterized by more severe organic and cutaneous involvement and excess mortality. This would allow for more aggressive management from the outset at an early onset of the disease. In general, it is known that this pathology is characterized by dysfunction of endothelial cells (EC) and fibroblasts as well as autoimmunity. Many mediators contribute to the fibroblast activation observed in SSc. However, transforming growth factor beta (TGFβ) is considered to be the central regulatory factor of fibrosis processes. It is also known that endothelial cells interact with mast cells through the production of Stem Cell Factor (SCF) to induce their proliferation and differentiation. The damaged skin tissues in systemic sclerosis are infiltrated in particular by mast cell cells which produce TGFβ. The team of Kihira et al (1998) demonstrated the presence of a high level of SCF in the serum of patients with systemic sclerosis. Few studies explore this possible production pathway of TGFβ in systemic sclerosis via SCF assay. This study will allow the investigators to: - study this possible route of fibrosis through the dosage of SCF in the serum of patients suffering from systemic sclerosis - describe SCF as a possible biomarker of skin involvement by hypothesizing that the dosage of SCF will be higher in patients with diffuse scleroderma compared to those with limited scleroderma
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of RO7303509 treatment in participants with systemic sclerosis (SSc) during a multiple-ascending-dose (MAD) portion of the trial. In the MAD phase, increasing doses of study drug will be tested sequentially. For each dose tested, the MAD stage will consist of a treatment period of 12 weeks followed by either a safety follow-up period of 13 weeks or continued treatment in an optional open-label safety extension (OSE) stage of 52 weeks to assess the long-term safety. All patients in the OSE stage will receive RO7303509 and no patient will receive placebo.
The cannabinoid has benefits in many aspects but the evidence of the effect of cannabinoids in humans with SSc is limited. We, therefore, would like to investigate the efficacy of cannabinoids on the appetite, sleep efficiency, quality of life, pain, and critical cytokine level in SSc compared with placebo in SSc patients and the adverse events associated with cannabinoids in those patients.
Systemic sclerosis (SSc) is a heterogeneous systemic autoimmune disease with distinct prognosis according to patients. In patients with systemic sclerosis, interstitial lung disease (ILD) concerns almost 50 % of patients and represents the main cause of mortality. Disease course in SSc-ILD is highly variable: patients can experience stable disease, slow or fast progression. Prevention of ILD progression now represents a key objective of SSc-ILD management. The understanding of the course and patterns of SSc-ILD progression is necessary, as reliable prediction tools that allow the stratification of the risk of progression. We aimed to identify the longitudinal trajectories of ILD in SSc patients using latent class mixed models and to examine their associations with SSc characteristics.
This is a randomized, double-blind, placebo-controlled, multicenter, multinational study investigating the effect of riociguat (MK-4836) in patients with early pulmonary vascular disease.
Systemic Sclerosis (Ssc) is a rare, systemic autoimmune disease characterized by skin fibrosis and vasculopathy. In addition to the skin, it is a heterogeneous disease that affects multiple organs, including the musculoskeletal, cardiac, pulmonary, and gastrointestinal systems. Patients may experience many symptoms such as pain, fatigue, dyspnea, impaired hand function, dry mouth, and difficulty sleeping. As a result of these symptoms, these patients may experience a decrease in activities of daily living, physical activity level and quality of life, while psychological problems such as anxiety and depression may increase.
This is a Phase I, single arm, open label, single center pilot study to assess a reduced-intensity conditioning regimen, bone marrow transplantation with high dose cyclophosphamide (PTCy) in recipients with refractory systemic sclerosis. This study expects to enroll 15 donor/recipient pairs for a total of 30 participants. The primary objective of this study is to assess the safety of using a reduced intensity condition (RIC) preparative regimen bone marrow transplant (BMT) with post-transplant cyclophosphamide for graft vs host disease (GVHD) prophylaxis as treatment for patients with scleroderma. Safety events are grade III-IV GVHD and treatment related mortality within 1 year. Eligibility includes patients >18 years who are eligible for transplantation according to the BMT Policy Manual, meet the 2013 ACR/EULAR Criteria for Systemic Sclerosis and display active diffuse cutaneous disease. The trial also includes analyses of the effects of BMT on skeletal and cardiac muscle using systemic scleroderma serum biomarkers of CK, aldolase, and troponin as well as periodic monitoring of circulating scleroderma auto-antibody titers, autoreactive T cells, and flow cytometric signatures over the one-year study period to correlate with response.
This study intends to carry out a prospective, multi-center cohort study based on MRI to explore the incidence of structural and functional damage of central, brain and kidney in patiant with SSc and its clinical relevance, and to search for the characteristics of serological markers of structural and functional damage of heart, brain and kidney.
The pathophysiology of systemic sclerosis (SSc) is still poorly understood and there are no effective treatments for this disease. SSc is a heterogeneous disease with varying severity. The heterogeneity of fibroblast profiles, observed in other fibrosing pathologies, has never been thoroughly explored in the skin of SSc patients. The immune system, and in particular B lymphocytes, plays a central role in the pathophysiology of SSc. The interactions between B lymphocytes and the cells responsible for excess collagen production, i.e. fibroblasts, are not fully elucidated The main objective is to analyze the heterogeneity of fibroblasts and infiltrating immune cells as well as their molecular signature in the skin of patients with SSc
People living with Systemic autoimmune rheumatic diseases (SARDs) face a new and urgent dilemma: immunosuppression increases risk for worse COVID-19 infection, yet an immune stimulation, such as vaccination, could re-activate their disease. Fear of vaccine-related disease reactivation is not of concern in other immunosuppressed groups (e.g. patients receiving chemotherapy or hemodialysis) but in SARDs, disease flare could lead to organ failure or even death. Specific research in this population is therefore critical. Moreover, among SARD patients, those on anti-CD-20 monoclonal antibody (mAb) (i.e. rituximab (anti-CD-20 mAb)), a medication used to treat inflammatory types of arthritis, have extremely low immunity post-COVID-19 mRNA vaccine. This study will test the hypothesis that a booster dose of a COVID-19 vaccine is safe and enhances post-vaccine humoral and cellular responses in SARDs patients on anti-CD-20 mAb treatment. The magnitude of this response depends on the type of COVID-19 vaccine administered and is optimal when the booster dose is a vaccine from a different group than the one used for primary immunization (mix-and-match approach).
