Filter by:Background: - An acquired heart disease is one that a person gets after they are born. Two of these are rheumatic heart disease (RHD) and endomyocardial fibrosis (EMF). They are found more commonly in people who live in Africa than in other places in the world. Researchers want to learn more about these diseases. They especially want to know what role genes and other factors play in them. Objective: - To identify genetic risk factors for RHD and EMF in sub-Saharan Africa. Eligibility: - Children and adults with RHD or EMF. - Healthy volunteers over age 10. Design: - Participants will come from existing study groups in Uganda and Nigeria. - Participants may be required to provide a sample of their DNA. They will do this with either a blood or saliva sample or a swab of the mouth. - Collected samples will be labeled with a code and sent to a lab in the United States for analysis. Remaining portions of participants samples will be stored for an unlimited period of time. They may be used in future studies. - Some genetic and health information from participants might be placed into one or more scientific databases. - Participant names and identifying information will be kept private. But there is a small chance someone could trace them from their genetic information.
Rheumatic fever (RF) is an autoimmune disease that is mediated by the cellular and humoral immune response that follows an untreated pharyngeal Streptococcus pyogenes infection. The most serious complication is rheumatic heart disease (RHD), one of the most common problems facing children and young adults worldwide, which leads to chronic valvular lesions. It is estimated that 60% of all acute rheumatic fever cases will develop RHD. The pathogenesis of RHD is complex with both environmental and genetic factors contributing to its etiology. The investigators know little about the genetic etiology, cellular events and modifiers of progression of RHD, and there exists a wide range of disease severity and progression to severe valve pathology. Thus, the investigators will study the genetics of RHD in Rwanda, a country with a very high incidence of RHD, using a combination of next-generation targeted exome capture, transcriptomics, and expressed quantitative trait loci (eQTL) analysis.
The purpose of this study is to evaluate the efficacy and safety of rivaroxaban compared with placebo in the prevention of symptomatic venous thromboembolism (VTE) events and VTE-related death post-hospital discharge in high-risk, medically ill patients.
Despite leading cause of morbidity, treatment strategies for Rheumatic diseases are geared almost exclusively toward medical-pharmacological area away from offering the patient the possibility of an interdisciplinary approach to their disease. Present study test whether treatment of physiotherapy reduces stiffness and pain inherent in rheumatic disease and improve their quality of life related to health.
The objectives of this study are to assess the safety, effectiveness, and immunogenicity of AA4500 in the treatment of adhesive capsulitis.
We aimed to investigate if adiponectin facilitates diagnosis of ARF by analyzing adiponectin levels in acute and convalescent periods of the acute rheumatic fever and by comparing results with that of healthy control group; also by comparatively examining levels of adiponectin in ARF cases who had different clinical findings at presentation. In addition, we aimed to investigate its role in the pathogenesis of ARF by evaluating correlations with cytokines such as TNF-α, IL-6 and IL-8 and acute phase reactants.
The purpose of this study is to investigate the effects of heated pool group exercises for patients with inflammatory rheumatic diseases with regard to symptoms (pain, fatigue, stiffness and ability to carry out daily activities).
The objective of this study is to identify genetic predictors of individual methotrexate (MTX) response in patients with rheumatic diseases by determining genetic and metabolomic factors related to nutrient metabolism and drug transport. The development of better genetic predictors of individual MTX treatment response would provide invaluable prognostic information prior to initiating treatment, which would allow more appropriate choice of therapy, decreased adverse events, and more efficient dose-escalation of the drug, with ultimate benefits of improved effectiveness and tolerability rates in patients being treated with MTX for autoimmune diseases. Despite being the gold-standard therapy for rheumatoid arthritis and other types of chronic autoimmune diseases since 1951, MTX's efficacy and safety profile limit its use: MTX is discontinued in greater than 50% of patients secondary to inefficacy or poor tolerability. Upon initial treatment, discontinuation rates approach 12% because of drug toxicity, despite prophylactic measures such as the co-administration of folic acid. The causes of primary failure, secondary failure, and adverse events of MTX may be related to genetic variation of dihydrofolate reductase (DHFR) and other genes involved in folate metabolism, one-carbon transfer, and drug transport. The purpose of this study is to identify genetic variations involved in methotrexate response so that we may better understand the pharmacodynamics of MTX metabolism in patients with rheumatic diseases.
We aim to investigate the efficacy of N-acetylcysteine (NAC) to attenuate acute renal dysfunction in patients with rheumatic valvular heart disease undergoing single valve replacement.
The purposes of this study 1. to compare the positivity of tuberculin skin test(TST) and QuantiFERON-TB Gold (QFT-G), and determine the level of agreement between two tests in patients with rheumatic diseases 2. to evaluate the difference in the occurrence of active TB in patients who receive both QFT-G and TST compared with those who receive only TST for detecting of Latent tuberculosis infection(LTBI) who are candidates of TNF inhibitors.
