Active clinical trials for "Syndrome"

Background: Urticaria is a common itchy skin disorder that may occur spontaneously or on exposure to a physical trigger (called physical urticaria). Researchers are studying the genetic basis of a physically induced urticarial syndrome. Once called familial cold urticaria, this condition is now called familial cold autoinflammatory syndrome (FCAS). FCAS is an autoinflammatory disease, a group of inherited disorders characterized by unprovoked episodes of inflammation. Patients with FCAS often have hives, joint pain, and fever following general exposure to cold. Patients with FCAS have a mutation in a gene that makes a protein called cryopyrin. Cryopyrin seems to be involved with the production of a proinflammatory mediator called interleukin-1 (IL-1). Patients with FCAS and others with autoinflammatory syndromes have benefited from medication that blocks the effects of IL-1. Objectives: To investigate mechanisms that may cause physical hives or urticaria. To reproduce urticaria through challenge testing (procedures to test the skin for a reaction to a stimulus), followed by mast cell studies, measurement of IL-1, genetic studies, and other molecular studies to lead to a better understanding of urticaria and to design safe and more effective treatments. Eligibility: Patients between 6 months and 65 years of age with a documented history of clinically reproducible physical urticaria that triggers hives and that has been evaluated by a physician. Patients should have a letter of referral, including copies of pertinent medical history and laboratory studies, from a referring physician. Affected and nonaffected family members of such patients. Exclusion criteria include (1) the presence of conditions that may put the subject at undue risk, such as acute infection, severe thrombocytopenia (a lower than normal number of platelets in the blood), or significant cardiovascular disease; (2) any condition that would make the subject unsuitable for enrollment in this study; and (3) a history of HIV, other known immunodeficiency, or evidence of chronic Hepatitis B and/or C infection. Design: Researchers will conduct the following tests to verify which triggers cause the hives: History and physical exam to determine the relationship between the trigger and appearance of the hives. Blood samples for baseline screening (additional samples may be taken within 8 hours of triggering hives). Verification of hives using standard challenge testing. Procedures to trigger urticaria (the challenge testing) include dermatographism (stroking the skin), delayed pressure urticaria (direct pressure), cold-induced urticaria (cold exposure), cholinergic urticaria (exercise, hot water), solar urticaria (sun exposure), localized heat urticaria (direct heat exposure), aquagenic urticaria (room temperature water), and vibratory angioedema (direct vibratory stimulus exposure). Participants who have a positive history for hives and failed challenge testing (that is, hives resulted from the triggers) will be asked to provide a skin biopsy and additional bloods samples for research purposes. Participants will be asked to return to the clinic within 1 month if multiple triggers could not be verified during the initial visit, or to return for additional research evaluations, which may include a skin punch biopsy and blood sample collection. Patients may have to stay at the hospital overnight, if required to document the disease. Nonaffected family members who enroll in this protocol will provide samples for comparison with the family member who has a history of hives. Participants will receive a small financial compensation for the skin biopsy.

Background: -Sjogren s syndrome is a disease that affects about 1-4 million Americans. It is more common in women. It mainly affects the glands that produce saliva and tears, leading to dry eyes and dry mouth. The cause of Sjogren s syndrome is unknown, but inflammation plays an important role. The purpose of this study is to learn more about Sjogren s syndrome. Objectives: -To better understand how Sjogren s syndrome begins and how it affects patients so that we can develop better ways to treat them. Eligibility: Participants must be 16 years of age or older. They must have a diagnosis of Sjogren s syndrome or have at least two symptoms of Sjogren s syndrome. Design: People taking part in the study will come to the NIH Clinical Center for at least three visits. During these visits, participants will have a medical history and physical exam. They will have oral and dental assessments, and saliva collection. Lab tests (blood and urine) and dry eye exams will be done. Participants will answer questionnaires and have salivary scintigraphy (adults only unless required for diagnosis). Other optional tests may also be done. Participants may have to come in for additional visits if they have these optional tests or if their disease changes. The only treatment provided as part of this study is for medical emergencies or complications that occur while you are at NIH for evaluation.

The Congenital Muscle Disease Patient and Proxy Reported Outcome Study (CMDPROS) is a longitudinal 10 year study to identify and trend care parameters, adverse events in the congenital muscle diseases using the Congenital Muscle Disease International Registry (CMDIR) to acquire necessary data for adverse event calculations (intake survey and medical records curation). To support this study and become a participant, we ask that you register in the CMDIR. You can do this by visiting www.cmdir.org. There is no travel required. The registry includes affected individuals with congenital muscular dystrophy, congenital myopathy, and congenital myasthenic syndrome and registers through the late onset spectrum for these disease groups. The CMDIR was created to identify the global congenital muscle disease population for the purpose of raising awareness, standards of care, clinical trials and in the future a treatment or cure. Simply put, we will not be successful in finding a treatment or cure unless we know who the affected individuals are, what the diagnosis is and how the disease is affecting the individual. Registering in the CMDIR means that you will enter demographic information and complete an intake survey. We would then ask that you provide records regarding the diagnosis and treatment of CMD, including genetic testing, muscle biopsy, pulmonary function testing, sleep studies, clinic visit notes, and hospital discharge summaries. Study hypothesis: To use patient and proxy reported survey answers and medical reports to build a longitudinal care and outcomes database across the congenital muscle diseases. To generate congenital muscle disease subtype specific adverse event rates and correlate with key care parameters.

This faisability study aims to evaluate the adhesion of the patient to a multidisciplinary program (adapted physical activity, coaching and nutrition)

The ASSESS national multi-center prospective cohort (Assessment of Systemic complications (Signs) and Evolution in Sjögren's Syndrome "SS") was set up in 2006 thanks to a grant of the French Ministry of Health. Fifteen centers for autoimmune diseases consecutively included consecutive patients with Primary Sjögren's Syndrome "pSS" fulfilling American-European Consensus Criteria (AECG) between 2006 and 2009. The study was approved by the Ethics Committee of Bichat Hospital in 2006. All patients gave their informed written consent. This study was followed for 5 years with the grant of the French Ministry of Health and this study will be extended for 20 years by French Society of Rheumatology (SFR). On an annual basis for a duration of 20 years, a thorough standardized paper case report form (CRF) was filled prospectively by clinicians.

The Center for Autonomic Medicine in Pediatrics (CAMP) has built the first International CCHS (Congenital Central Hypoventilation Syndrome REDCap (Research Electronic Data Capture) Registry. This registry is an international collaboration with CCHS patients and their physicians recruited from around the world. The purpose of this IRB-approved research study is to gain a better understanding of the various clinical manifestations of CCHS with advancing age, and as related to each patient's specific PHOX2B mutation. With a better understanding of specific CCHS PHOX2B mutations and associated disease manifestations, we will be able to better anticipate healthcare needs and to provide more accurate guidelines to healthcare providers world-wide in caring for patients with CCHS. The study aims to obtain detailed phenotypic information (information about health and well-being) on patients with CCHS. Participation would require filling out a confidential survey that asks questions regarding phenotype and past medical history. Involvement in the project is completely voluntary and there is no compensation for taking part. However, this project will help us learn more about this devastating disease, with the goal of advancing treatment.

Polycystic ovary syndrome (PCOS) affects 10% of all women and usually presents with irregular menstrual periods and difficulties conceiving. However, PCOS is also a lifelong metabolic disorder and affected women have an increased risk of type 2 diabetes, high blood pressure, and heart disease. Increased blood levels of male hormones, also termed androgens, are found in most PCOS patients. Androgen excess appears to impair the ability of the body to respond to the sugar-regulating hormone insulin (=insulin resistance). The investigator has found that fat tissue of PCOS patients overproduces androgens and that this can result in a build-up of toxic fat, which increases insulin resistance and could cause liver damage. In a large cohort of women registered in a GP database, the study team have found that androgen excess increases the risk of fatty liver disease. The aim is to identify those women with PCOS who are at the highest risk of developing metabolic disease, which would allow for early detection and potentially prevention of type 2 diabetes, high blood pressure, fatty liver and cardiovascular disease. The investigator will assess clinical presentation, androgen production and metabolic function in women with PCOS to use similarities and differences in these parameters for the identification of subsets (=clusters) of women who are at the highest risk of metabolic disease. The investigator will do this by using a standardised set of questions to scope PCOS-related signs and symptoms and the patient's medical history and measure body composition and blood pressure. This standardised recording of a patient's clinical presentation (=clinical phenotype) is called Phenome analysis. The investigator will collect blood and urine samples for the systematic measurement of steroid hormones including a very detailed androgen profile (=steroid metabolome analysis) and of thousands of substances produced by human metabolism (=global metabolome analysis). Phenome and metabolome data will then undergo integrated computational analysis for the detection of clusters predictive of metabolic risk.

The main purpose of this study is to investigate the feasibility of a follow-up larger RCT on the efficacy of Botanical Tincture to relieve abdominal pain in people with Irritable Bowel Syndrome Constipation Predominant (IBS-C).

Interventional, comparative, open label, single-center study to demonstrate that an early (from 6 months of age) and systematic (every 6 months) screening of Obstructive Sleep Apnea (OSA) by polysomnography (PSG) in children with Down Syndrome during the first 3 years of life is associated with an improved neurocognitive development at the age of 3 years.

The purpose of this study is to evaluate the safety of reducing dual antiplatelet therapy (DAPT) duration to 1 month after implantation of the everolimus-eluting cobalt-chromium stent (CoCr-EES) under the setting of acute coronary syndrome (ACS).
