4 Clinical Trials for Various Conditions
Background: - Lymphatics are a type of vessel, similar to arteries and veins. Lymphatic disorders happen when these vessels don t work properly. Researchers want to look for a relationship between lymphatic disorders and variations of certain genes found in the lung, blood, and other places in the body. Objective: - To learn more about lymphatic disorders and evaluate how genetic factors affect lymphatic disorders. Eligibility: * People ages 2 90 who have a lymphatic disorder or relatives of people with lymphatic disorders. * Healthy volunteers 18 and older. Design: * Participants may have 1 2 visits a year, or more as needed. The study is expected to last 5 years. Visits may last 1 5 days. Participants may have lab tests, medical history, and physical exam at each visit. * Participants may have blood testing that includes genetics tests, and urine tests. They may have nose and throat cultures, saliva collection, and cheek swabs to collect samples. * Participants may have a skin biopsy and have blood taken from an artery. * Participants may have breathing tests and be studied while exercising. * Participants may have an electrocardiogram. Electrodes will be placed on their chest, tracing heart rhythms. They may also have chest X-rays. * Participants may have a bronchoscopy. A thin, flexible instrument will be passed through the nose or mouth, into the lung. A tissue sample will be taken. * Participants who have lymphatic disease or have a relative with it may also have: * CT scans. They will lie on a table and hold their breath while their chest is scanned. * MRI. They will lie flat on a table that slides in and out of a scanner. * ultrasound. A probe is rolled around outside the abdomen. * removal of fluid around the lungs, chest, and abdomen.
The purpose of this study is to determine if the use of sirolimus in the treatment of children and young adults with complicated vascular anomalies will prove to be safe and provide objective response resulting in improved clinical status and quality of life.

Background: The lymphatic system is a network of vessels that carry a clear fluid called lymph through the body. Problems in the lymphatic system can cause pain, fluid buildup, and issues with immunity. There is much researchers do not understand about lymphatic anomalies. In this natural history study, they will collect data from a lot of people over a long time. Objective: To better understand why lymphatic anomalies develop. The goal is to improve future treatments. Eligibility: People aged 0 days and older with a suspected or confirmed lymphatic anomaly. Their unaffected parents or siblings aged 7 years or older are also needed. Design: Participants may remain in the study indefinitely. Affected participants may be evaluated every 10 months to 2 years. Some participants will be seen over telemedicine. Others will be seen at the NIH Clinical Center for 2-5 days. All participants will have a physical exam. They may provide specimens including blood, saliva, hair follicles, stool, skin, and other tissues. Samples may be used for genetic testing. Participants may undergo other tests depending on their medical conditions. The NIH Clinical Center visit may include: Heart tests include placing stickers on the chest to measure electrical activity and using sound waves to capture pictures of the heart. A lung test measures the muscle strength in the chest. Participants will blow into a tube. Photographs may be taken of participants faces and other features. Imaging scans will take pictures of the inside of the body. One scan will measure bone density. One type of scan tracks how lymph fluid moves through the body. Participants will be under anesthesia, and they will be injected with a dye.
The purpose of the International Lymphatic Disease and Lymphedema Patient Registry and Biorepository is to collect health information in order to study the disease classification, natural history, and impact of Lymphatic Disease, Lymphedema and Related Disorders and its treatments and medical outcomes.
