Screening Volunteers for Clinical Trials
Background \- The National Institute of Allergy and Infectious Diseases (NIAID) at the National Institutes of Health needs healthy volunteers for vaccine clinical trials. This is a screening study that is used to identify healthy volunteers who may be eligible to participate in other clinical trials at the Vaccine Research …
Human Biospecimen Procurement Protocol: Biorepository to Support Translational Research to Identify Disease Mechanism(s)
Background Studies show that rare genetic variants might lead to diseases. Researchers want to collect blood and tissue samples so they can study them and better understand diseases. Objective To collect blood and tissue samples for studies to identify underlying causes of disease. Eligibility People of all ages Design Participants …
Clinical Trial of Approaches to Prostate Cancer Surgery
This is a prospective, randomized controlled trial to compare cancer control and health-related quality of life following pelvic fascia-sparing radical prostatectomy versus standard radical prostatectomy. The investigators hypothesize that pelvic fascia-sparing radical prostatectomy will have similar cancer control (primary outcome) and sexual function outcomes; and significantly better urinary function, penile …
Longitudinal Early-onset Alzheimer's Disease Study Protocol
The Longitudinal Early-onset Alzheimer's Disease Study (LEADS) is a non-randomized, natural history, non-treatment study designed to look at disease progression in individuals with early onset cognitive impairment. Clinical, cognitive, imaging, biomarker, and genetic characteristics will be assessed across three cohorts: (1) early onset Alzheimer's Disease (EOAD) participants, (2) early onset …
Inherited Reproductive Disorders
Background \- During puberty, children begin to develop into adults. Problems with the hormones released during puberty can affect the reproductive system. Some people have low hormone levels that severely delay or prevent puberty. Others start puberty abnormally early. Other people may have a normal puberty but develop reproductive disorders …
Studies of Dermatologic Diseases Biospecimen Acquisition Protocol
Background \- Skin disease can have many causes. It can have widespread consequences, and in rare cases can lead to death. Researchers want to determine the causes of various types of skin diseases and find a way to treat them. Objectives \- To determine the causes of various skin diseases …
Evaluation of Patients With Liver Disease
The proposed study aims to evaluate, investigate, and follow-up patients suffering from acute and chronic liver disease. The study will focus on understanding diseases affecting the liver. Patients participating in the study will first undergo a routine check-up as an outpatient. They will be asked to provide blood and urine …
Adult and Juvenile Myositis
This study will evaluate subjects with adult- and childhood-onset myositis to learn more about their cause and the immune system changes and medical problems associated with them. Myositis is an inflammatory muscle disease that can damage muscles and other organs, resulting in significant disability. Children or adults with polymyositis or …
Studies of the Pathogenesis of HIV Infection in Human Peripheral Blood Cells and/or Body Fluids in People Living With and Without HIV
We are studying virologic and/or immunologic parameters of HIV infection and other infectious or non-infectious immune deficiency diseases in order to better understand the pathogenesis of HIV. Because of the lack of an adequate animal model it is generally necessary to utilize human peripheral blood cells for studying aspects of …
Clinical and Laboratory Study of Methylmalonic Acidemia
Methylmalonic acidemia (MMA), one of the most common inborn errors of organic acid metabolism, is heterogeneous in etiology and clinical manifestations. Affected patients with cblA, cblB and mut classes of MMA are medically fragile and can suffer from complications such as metabolic stroke or infarction of the basal ganglia, pancreatitis, …
