Filter by:This study has been designed as a 52-week, randomized double blind placebo controlled multicenter clinical trial. The study aims to compare the efficacy and safety of two treatment strategies in IgG4-RD patients with re-elevation of serum IgG4 level during maintenance remission period: basic maintenance treatment group (continue use of basic maintenance treatment of IgG4-RD) and enhanced treatment group (use low dose mycophenolate mofetil as an add-on therapy of basic maintenance treatment of IgG4-RD).
Ambispective, national, multicenter observational cohort study aimed at characterizing the satellite dysimmune manifestations of clonal hematopoiesis, including Vexas (Vacuoles, E1 enzyme, X-linked, Autoinflammatory and Somatic) syndrome.
Argonaute (AGO) proteins have been described as the target of antibodies in several autoimmune diseases including Sjögren Syndrome (SS). Sensory neuronopathies (SNN) are disorders affecting neurons in the dorsal root ganglia that may depend on an inflammatory process. However, identifying these cases needs the availability of specific biomarkers. The aim of this study is to test the prevalence of anti-AGO antibodies in a population of patients with Sensory neuronopathies (SNN) with and without associated autoimmune disease in comparison with other peripheral neuropathies to determine how anti-AGO antibodies may help the identification of potentially dysimmune Sensory neuronopathies (SNN).
The goal of this observational study is to explore the influence of Covid-19 infection and risk factors of severe outcomes in vulnerable population including patients with chronic liver disease, malignant tumor, autoimmune disease, medical staff. The main questions it aims to answer are: 1. The clinical characteristics of vulnerable population after Covid-19 infection. 2. Risk factors for severe illness in vulnerable groups after infection with the Covid-19. 3. The impact of Covid-19 infection on the progression of underlying diseases. Information of participants will be collected such as gender, age, underlying diseases, medication status, vaccination status, clinical and biochemical indicators. Researchers will compare the mild and severe outcomes after Covid-19 infection to identify the "truly vulnerable" population and explore the potential mechanism and intervention for these population.
Autoimmune diseases are the consequence of an abnormality of the immune system, leading it to attack components of our own body. They have a wide variety of presentations. They preferentially affect women, and often at a young age. Systemic lupus erythematosus, for example, most often occurs between the ages of 15 and 40. Inflammatory rheumatism, such as spondyloarthritis or rheumatoid arthritis, is less prevalent in women, but also affects young people, and is particularly common. Several disease-modifying treatments exist, depending on the severity and evolutivitý of the disease. Some are contraindicated or not recommended during pregnancy and therefore require supervision of pregnancy plans. In addition, some treatments have an immunosuppressive activitý, which implies an annual screening of cervical lesions by cervico-uterine smear. In this context, an adapted gynecological follow-up seems indispensable. The rheumatologist and the internist physician have a crucial role in advising and referring patients to their gynecological colleagues. Studying the qualitý of this gynecological follow-up in a cohort of patients with autoimmune disease or inflammatory rheumatism is of major interest.
Serological positivity for anti Ro-SSA antibodies is frequently found in pathologies such as Sjogren's Syndrome and SLE. Worldwide, approximately 0.5-1% of women of reproductive age are positive for Ro-SSA antibodies, and in 1-2% of these women, pregnancy will be complicated by cardiac abnormalities of the fetus, particularly varying degrees of atrioventricular block. It is essential to promptly identify patients with fetal heart rhythm abnormalities to prevent both intrauterine deaths and the birth of newborns with third-degree atrioventricular block, requiring lifelong cardiac pacing. At the moment, the only means to identify these alterations is represented by fetal cardiac ultrasound. Fetal atrioventricular block can develop within a few hours in these patients and fetal ultrasound, normally performed no more frequently than once every two weeks, does not allow for the timely identification of these conditions and therefore for pharmacological intervention. Using home fetal heart rate monitoring, carried out directly by patients three times a day with the aid of a special device that allows easy identification of the fetal heart rhythm, would allow rapid recognition of rhythm alterations and early access to confirmation tests and possible therapies. Fetal heart rhythm surveillance could detect a medically reversible disease that, if untreated, would progress to lifelong cardiac pacing, with its many associated comorbidities. Applying such protocol in pregnant women anti-Ro/SSA positive could become standard practice. The main objectives of this study are: - Estimation of the incidence of the development of fetal AV conduction abnormalities in patients with positivity for Ro/SSA autoantibodies; - Estimation of the reliability of home monitoring of fetal heart rate with fetal Doppler device in detecting fetal atrioventricular conduction disturbances; - Evaluation of the results of the therapy administered early, immediately after the diagnosis of fetal atrioventricular conduction disorders.
The goal of the study is to detect autoantibodies in the serum of the women with PCOS and evaluate the obesity markers to investigate the the role of autoimmunity and obesity in PCOS
1. To evaluate the frequency of LILRA3 in Ankylosing spondylitis and Axial psoriatic arthritis patients. 2. To investigate the association of LILRA3 with Ankylosing spondylitis and Axial psoriatic arthritis disease activity and severity.
The investigators will conduct a randomized controlled trial (RCT) to examine how an online training and peer support platform could help the preparation to transition to adult care. Among 14-16 year old youth with Type 1 Diabetes (T1D), the investigators aim to assess the effect of an online training and peer support platform (Support-t) integrated in usual care, compared with usual care on Hemoglobin A1c (HbA1c), adverse outcomes and psychosocial measures during the preparation for transition to adult care. The investigators will conduct a multi-site, parallel group, blinded (outcome assessors, data analysts), superiority RCT of adolescents with T1D (14-16 years of age) followed at one of 4 university teaching hospital-based pediatric diabetes clinics in the province of Quebec.
The goal of clinical trial is to evaluate the safety and tolerability of SCT650C in healthy participants.
