Active clinical trials for "Rheumatic Diseases"

Rheumatic mitral stenosis remains a health problem in developing countries. Progressive fibrosis of the valves and myocardium is the main pathophysiology that plays an important role. Dapagliflozin has various beneficial effects on the heart by reducing fibrosis, reducing inflammation, and improving patient quality of life. However, the role of this therapy is unknown in patients with rheumatic mitral stenosis.

this study aims to determine if nociplastic pain mediates the relationship between rheumatoid arthritis (RA) severity and cognitive impairment in geriatric patients 100 patients aged 65-90 years with long-standing RA and assess their disease severity, cognition, and pain sensitization will be recruited. Expectations that patients with more severe RA will have worse cognitive function, and that this relationship will be mediated by higher levels of nociplastic pain.

Acute Rheumatic Fever is an autoimmune inflammatory post-infectious syndrome, mainly caused by type A streptococcus. It is characterized as an inadequate immune response. It may provoke carditis, combined with articular, skin and neurologic signs. Only carditis, prevalent in 60% of acute rheumatic diseases, may provoke valvular sequels, which define rheumatic cardiopathy. Antibiotherapy based on penicillin is the standard treatment of both acute rheumatic fever and its prevention. Although no anti-inflammatory treatment has proved its efficacy, with or without steroids anti-inflammatory treatments are administered in acute episode of ARF. Up to date, only prevention strategies have shown efficacy.

Janus kinase (JAK) inhibitors are a new class of molecules available to the therapeutic arsenal for chronic inflammatory rheumatic diseases.The tolerance profile of this new class needs to be better defined and its use in real life further established. The French Society of Rheumatologists intends to coordinate a prospective national registry study for this follow-up. This registry will include at least 1500 Rheumatoid Arthritis (RA) and 150 patients with psoriatic arthritis from the start of treatment with JAK inhibitor and then followed for 5 years. This registry is a longitudinal, multicentre, observational registry study. The objective of this national registry is to get a better understanding of the safety profiles of JAK inhibitors and get knowledge of their use in daily practice in order to optimize this use and potentially integrate JAK inhibitors into personalised medicine strategies. This registry will generate efficacy data, especially therapeutic maintenance, observation, allowing inter-registry comparisons with other biologic compounds in the French population, and can be aggregated with other similar registries in other countries.

rheumatic heart disease remains the majority valvular disease in low and middle income countries, which mostly affected mitral valve, surgical treatment is the most effective strategy to improve the outcomes of middle or late-stage RHD patient, however, whether mitral valve repair surgery is superior to replacement or other evolving interventional device remains controversial, this study aims to investigate the results of repair surgery compared with replacement or other treatment strategy from international multicenters.

The primary objective of this study is to determine the impact of a pragmatic RHD primary prevention program in Uganda. The secondary Objective are as follow: To improve guideline-based care for sore throat through frontline healthcare provider education on clinical decision rules and guideline-based primary prevention. To increase health seeking behavior for sore throat thorough a multifaceted community awareness campaign.

The purpose of the study is to evaluate the ability of placental angiogenesis markers to predict the risk of PE in pregnancy in women with primary APS. To construct reference intervals of placental angiogenesis markers specific to women affected by primary APS in pregnancy by measuring the levels of sFlt-1and PlGF in serum maternal serum and their sFlt-1/PlGF ratio during the trimesters of gestation (I TM, II TM and III TM). For this aim the study will involve recruiting two groups of subjects, one will be cases and one will be controls.

Background: - The rare disease melorheostosis causes bones to thicken. This may lead to pain, and can affect bones, joints, and muscles. Researchers want to learn more about the disease and how it progresses. Objective: -To see what happens to people with melorheostosis over time and understand the causes of the disease. Eligibility: People 18 and over with melorheostosis. Their unaffected relatives. Design: All participants will have a medical history and physical exam. Participants who are relatives will give samples of blood or cheek cells. Other participants will be in the study for about 1 week. They will have blood and urine collected. Strength, walking, and range of motion will be measured. Participants may also have X-rays and scans. A pain and neurological evaluation. Their skin evaluated by a dermatologist. A small sample of bone taken. Nerve conduction studies. Small electrodes with to wires will be put on the skin. A metal probe will give a small electrical shock. Electromyography. A thin needle will be placed into the muscles. An ultrasound, which uses sound waves to examine the muscles and nerves. An ultrasound probe will be placed over the skin. A bone scan. They will get a small amount of radioactive fluid through a needle in an arm vein. This fluid travels to the bones. The bones will be photographed in a machine. Bone Densitometry, a low-level x-ray. Photographs taken. A small circle of skin removed with a surgical instrument. Questionnaires about their quality of life. Participants will be asked to return about every 2 years. At these visits, participants may have blood and urine tests and x-rays.

This study will explore the causes of rheumatic diseases and why many of them affect certain minority communities more severely. Rheumatic diseases may cause joint pain, stiffness or swelling. Some can involve bones, muscles, tendons or ligaments. Some cause abnormalities of the immune system the body s defense against disease. Some rheumatic diseases are painful or deforming and some can be life threatening. Information obtained from this study will be used to learn about the disparities in rheumatic disease in the minority community and to design further, more targeted, research studies to address this issue. Patients with known or suspected rheumatic disease 18 years of age or older may be eligible for this study. Candidates will undergo a medical history and physical examination to confirm the diagnosis of rheumatic disease and determine what is needed for evaluation and treatment. Participants will receive standard medical care for rheumatic disease and arthritis. No experimental treatments, medications or procedures will be included in this study. Procedures may include routine blood tests for blood chemistries, cell counts, and antibodies commonly found in patients with rheumatic disease; a urine test for proteins and cells; and X-rays and other imaging tests to check for abnormalities in the lungs or other organs. All medical information will be kept confidential. Patients who are found to be eligible for other current NIH research studies will be offered an opportunity to participate in these studies.

COVID-19 is a contagious respiratory disease that is caused Severe Acute Respiratory Syndrome causing Coronavirus-2 (SARS-CoV-2). The most common symptoms are fever, cough and dyspnoea. Patients with rheumatic diseases are at higher risk of infections because of disease activity and immunosuppression. In addition, old age and having concomitant chronic disease are among risk factors for coronavirus. Therefore, national health services recommend patients to practice self-isolation and self-quarantine.
