Filter by:Connective tissue disease (CTD) covers all heterogeneous and broad immunological diseases. These immunological diseases are characterized by inflammation, tissue damage, and abnormal repair. Disorders such as fibrotic tissue or loss of function are seen in the degeneration of the target organ. There is a complex relationship between genetic and environmental factors on the basis of these disorders. Vitamin D deficiency has been frequently observed in autoimmune diseases such as systemic lupus erythematosus, diabetes mellitus, and rheumatoid arthritis. Vitamin D deficiency is primarily seen with musculoskeletal complaints and is an early warning of osteomalacia. Muscle weakness is most common in the trunk, shoulders and hips. It is characterized by difficulty in climbing stairs, getting up from sitting or lying position, feeling of heaviness in the legs, duck-like gait, difficulty getting up from a chair, fatigue easily, inability to lift objects with arms and hands. Patients experience decreased exercise capacity as a result of pain and muscle weakness. In addition, vitamin D deficiency causes smooth muscle contraction and an increase in airway inflammation. As a result, it was observed that the disease course and symptoms were more severe in CVD patients with vitamin D deficiency. In a study conducted with rheumatoid arthritis patients, the quality of life, physical activity and depression levels of patients with vitamin D deficiency were compared with the control group. The evaluation parameters of rheumatoid arthritis patients were worse than the control group. Vitamin D levels were compared with sleep, anxiety and depression levels in patients with systemic lupus erythematosus. A positive relationship was found between vitamin D deficiency and sleep disturbance level. It has been observed that the life expectancy of patients with connective tissue disease is significantly reduced compared to healthy ones. Exercise capacity and oxygen consumption decreased in these patients.
This prospective, open-label, single-center, one-arm clinical trial aims at evaluating the efficacy and safety of avatrombopag in Chinese adult Immune Thrombocytopenia (ITP) patients with autoantibodies fail (due to intolerance or resistance) to eltrombopag or herombopag treatment.
Connective tissue disease (CTD) is a common group of autoimmune diseases, mainly including systemic lupus erythematosus (SLE), antiphospholipid syndrome (APS) , and so on. APS is caused by autoimmune disorders that cause recurrent miscarriage, thrombosis, and thrombocytopenia, and often secondary to connective tissue diseases such as SLE. Undifferentiated connective tissue disease (UCTD) is currently considered to be an independent disease in the classification of CTD. And women of childbearing age who suffer UCTD is more common than that in other definite CTDs. Therefore, the impact of the disease flare and the influence of medicine on pregnancy and lactation are important for these patients who may suffer high-risk of abnormal pregnance.
This prospective, open-label, nonrandomized, multicenter clinical trial aims at comparing the efficacy and safety of combined use of TPO-RAs with low-dose anti-CD20 monoclonal antibody vs. the best available therapy（BAT）in adult immune thrombocytopenia with autoantibodies failed (due to intolerance or resistance) to first-line treatment.
Background: Elastic fibers affect parts of the body that stretch repetitively, such as the skin, blood vessels, and lungs. Researchers want to use medical and research tests in patients with already identified changes in a set of connective tissue genes to better understand diseases related to elastic fibers. Objective: To learn more about the impact of underlying changes in a set of connective tissue genes on people s overall health. Eligibility: People ages 2-100 who have had a gene test that identified a change in a gene that affects elastic fibers. Initial emphasis will be placed on people with changes in ELN, LOX, MFAP4, FBLN5 and EFEMP2. Design: Participants will visit the NIH for several days to perform tests that will help researchers learn more about how changes in connective tissue genes affect a person s health. They will also have clinicians take their medical history and physical exam. Optional tests include giving blood samples, hair strand, urine, and/or saliva samples. They may have a cheek swab or skin biopsy. Their genes may be studied. Their cells may be grown in a laboratory. Participants may have photographs taken of the face and body. They will receive exams by a medical team with experience in connective tissue disease. They may have a dental exam or eye exams and with photography. During the eye exam, pictures may be taken of the blood vessels in the eyes. If this occurs, they will get dye through an intravenous (IV) line in an arm vein. They will also have medical tests to check the health of tissues that may be affected by these connective tissue genes. Participants may have lung function tests. They may have a six-minute walk test. They may complete a treadmill or bike stress test. Their heart s electrical activity may be recorded. Participants may have X-rays and ultrasounds. They may have a DEXA scan to measure bone density. They may have CT, MRI or other imaging scans. Some of these tests require the participant to get a contrast fluid via IV. Participants may have a skin elasticity test using a suction cup that pulls lightly on their skin. Participants may wear blood pressure cuffs while probes are placed on their skin. The tests will be chosen for each individual based on their specific gene change and no person is expected to complete all tests. Participation will last 3-5 days.

In parallel with the growth of American Thrombosis and Hemostasis Network's (ATHN) clinical studies, the number of new therapies for all congenital and acquired hematologic conditions, not just those for bleeding and clotting disorders, is increasing significantly. Some of the recently FDA-approved therapies for congenital and acquired hematologic conditions have yet to demonstrate long-term safety and effectiveness beyond the pivotal trials that led to their approval. In addition, results from well-controlled, pivotal studies often cannot be replicated once a therapy has been approved for general use.(1,2,3,4) In 2019 alone, the United States Food and Drug Administration (FDA) has issued approvals for twenty-four new therapies for congenital and acquired hematologic conditions.(5) In addition, almost 10,000 new studies for hematologic diseases are currently registered on www.clinicaltrials.gov.(6) With this increase in potential new therapies on the horizon, it is imperative that clinicians and clinical researchers in the field of non-neoplastic hematology have a uniform, secure, unbiased, and enduring method to collect long-term safety and efficacy data. ATHN Transcends is a cohort study to determine the safety, effectiveness, and practice of therapies used in the treatment of participants with congenital or acquired non-neoplastic blood disorders and connective tissue disorders with bleeding tendency. The study consists of 7 cohorts with additional study "arms" and "modules" branching off from the cohorts. The overarching objective of this longitudinal, observational study is to characterize the safety, effectiveness and practice of treatments for all people with congenital and acquired hematologic disorders in the US. As emphasized in a recently published review, accurate, uniform and quality national data collection is critical in clinical research, particularly for longitudinal cohort studies covering a lifetime of biologic risk.(7)
The goal of this study is to determine whether anti-Ro/SSA antibodies are associated with acquired QT prolongation in subjects with connective tissue disease. The investigators will investigate whether gender or race influence correlation between anti-Ro antibody status and prolonged QT interval and the role of inflammatory cytokines in association with anti-Ro antibodies and QT prolongation. The investigators propose to add an additional objective to test whether QT prolongation is reversible with moderate doses of prednisone in patients with QT interval greater than 500 msec.
Despite a number of prospective studies already initiated in the past years, the current epidemiology and course of interstitial lung disease (ILD) and pulmonary hypertension (PH) in patients with connective tissue disease (CTD) is still not well defined, particularly regarding its prevalence, incidence and the management of a broad spectrum of disease presentations. Major challenges include the identification of patients with progressive disease, the appropriate time point of therapeutic intervention and the underlying driver of disease (inflammatory or pro-fibrotic stimulus or both?). To address these issues in Western Austria, a progressive registry of patients with CTD exploring routine clinical and pathophysiological characteristics of ILD and PH will be conducted. This multidisciplinary, prospective and observational registry aims to collect comprehensive clinical data on incidence, prevalence and course of disease regarding all PH and ILD presentations in a real-world setting.
