Active clinical trials for "Syndrome"

This is a prospective, observational, non-interventional, international, multi-center, mixed methods study that will involve the integration of quantitative and qualitative data in patients with MF/SS treated with Poteligeo.

Assessment of benefits of HVNI in management of obesity hypoventilation syndrome complicated with acute hypercapnic respiratory failure. Compare the value, safety and effectiveness of HVNI and NIV in patients with obesity hypoventilation syndrome complicated with acute hypercapnic respiratory failure.

Turner syndrome (TS) is characterized by a missing whole or part of the second sex chromosome in a phenotypic female, resulting in short stature due to haploinsufficiency of the SHOX gene. Growth hormone (GH) is an approved therapy for this condition, although not associated with GH deficiency, and benefits are modest. Vosoritide, a C-type natriuretic peptide (CNP) analog, targets chondrocytes within the growth plate leading to increased cell proliferation and hypertrophy. We hypothesize that patients with TS and short stature will respond to vosoritide treatment leading to increased growth velocity. This study will enroll pre-pubertal girls with TS who are either naïve to GH or have had a poor response to GH therapy. All subjects will be treated with vosoritide for 12 months and will be assessed for safety monitoring and improvement in height outcomes. Annualized growth velocity (AGV) on vosoritide will be compared to AGV in the 6-18 months prior to initiation of vosoritide based on historical data available in the medical record. Subjects with a positive response to therapy will be given the option to continue in the extension phase of the study during which they will continue to receive vosoritide until growth cessation.

This is a multicenter, single arm, open-label, extension study to evaluate the long-term safety, tolerability, and efficacy of iptacopan in participants with aHUS.

The primary purpose of The PCOS Challenge Study will be to conduct high-quality research where patients are included in the design, and answering the questions that patients identify as important to their lived experience with PCOS. In partnership with clinical investigators, patients will work on the development and management of data collection, the research agenda, and the sharing of research findings. The PCOSC Study will promote the advancement of research that provides reliable, useful, and meaningful information to patients with PCOS and their clinicians. The population for The PCOS Challenge Study will include individuals with a clinical diagnosis of PCOS, individuals self-diagnosed with PCOS, individuals with symptoms of PCOS (e.g., hirsutism, irregular menstrual cycles), and demographic-matched controls without PCOS.

Cushing's Syndrome is a rare disease resulting from prolonged exposure to high levels of circulating cortisol. Clinical manifestations are variable but many patients present a metabolic syndrome (abdominal obesity, insulin resistance, dyslipidemia, hypertension). With regard to the liver, experimental data have shown that excess cortisol leads in an increase in lipogenesis and a reduction in the oxidation of fatty acids. This, in association with an accumulation of visceral adipose tissue and deregulation of adipokines, may contribute to the development of hepatic steatosis in animals. However, few data is available in humans with only one study of 50 patients with Cushing's syndrome estimating the prevalence of hepatic steatosis at 20%. NAFLD (Non-Alcoholic Fatty Liver Disease), is defined as the presence of hepatic steatosis in the absence of secondary causes of intrahepatic fat accumulation. It is a heterogeneous disease ranging from simple liver steatosis, whose prognosis is generally considered to be benign, to inflammation (NASH, Non-Alcoholic Steato-Hepatitis) which may progress to fibrosis, cirrhosis and an increased risk of hepatocellular carcinoma. The prognosis for NAFLD is mainly related to the severity of hepatic fibrosis. In Cushing's syndrome, normalization of cortisol production is the most effective strategy to improve co-morbidities associated with hypercortisolism. However, some of these complications, especially the metabolic co morbidities, could not be completely reversible and no data is available about resolution of hepatic steatosis.

Background: Myelodysplastic syndromes (MDS) occur when the cells that make blood cells are abnormal. There are limited treatment options for MDS. Researchers want to learn more through this natural history study so they can develop better treatments. Objective: To study the natural course of MDS and MDS/myeloproliferative neoplasms (MPN) and collect biological samples that can help researchers understand the disease. Eligibility: People with suspected or confirmed MDS or MDS/MPN. Healthy donors are also needed. They can be people who are scheduled to donate bone marrow at NIH for a relative, or they may be providing bone marrow in another study. Design: Participants will be screened with a medical history. Participants will have a physical exam. They will give blood and urine samples. They will discuss their symptoms, medications, and ability to perform their normal activities. They will complete surveys about how they are feeling. Participants will have a bone marrow biopsy. A needle will be inserted through a small cut. Bone marrow will be removed. A small piece of bone may be removed. Participants may have an optional skin biopsy. Participants may give optional saliva and stool samples. They may collect these samples at home and mail them to NIH. Participants may undergo optional apheresis. One or two needles or intravenous (IV) lines will be placed in their arm, neck, or groin veins. Blood will be removed. A machine will separate out the white cells. The rest of the blood will be returned to the participant. Participants will be contacted for follow-up once a year for up to 20 years. Healthy donors will have marrow collected for this study during their scheduled procedure with no follow-up.

This study aims to measure the effectiveness of vitamins C and E on relieving RLS symptoms in end stage renal disease patients on HD

The purpose of the study is to compare the effect between of whole-body vibration and gravity force stimulation on postural stability in children with Down syndrome.

A cytotoxic complication caused by chemotherapy is hand-foot syndrome, also known as palmar-plantar erythrodysesthesia (PPE). The mechanism is not yet clear, but it is thought that the chemotherapeutic agent generates cytotoxicity on the acral epidermis. Clinically it manifests as erythema and edema on the palms of the hands and feet, dry and scaly skin, accompanied by a sensation of tightness and pain. Extreme cases present blisters and ulcerations that may require hospitalization. It can also be accompanied by paresthesias. The main objective will be to evaluate if photobiomodulation is effective in reducing PPE induced by Capecitabine and 5-Fluorouracil chemotherapy. It will be a 4 week treatment, with 2 groups: G1 - Moisturizing cream and Photobiomodulation; G2: Moisturizing cream and photobiomodulation sham.
