Leukapheresis to Obtain Plasma or Lymphocytes for Studies of HIV-infected Patients, Including Long-term Non-progressors

HIV

This study will collect white blood cells and plasma for research on how the immune system controls HIV infection. The immune system of a very small group of people with HIV, called non-progressors, has been able to control HIV for long periods without antiretroviral therapy. Some immune system-related genes important for this control have been identified in these patients. People living with HIV who are 18 years of age and older, documented or suspected long-term nonprogressors in generally good health may be eligible to screen for the study. Participants will undergo apheresis (a method for collecting larger quantities of certain blood components than can safely be collected through a simple blood draw) if venous access is adequate once yearly. Some may be asked to return every six months. * Automated apheresis - Blood is drawn through a needle placed in an arm vein and spun in a machine, separating the blood components. The white cells are extracted and the red cells, with or without plasma (liquid part of the blood), are re-infused into the donor through a needle in the other arm. An anticoagulant (medication to prevent blood from clotting) is usually added to the blood while in the machine to prevent it from clotting during processing. * Blood draw - a needle placed in an arm vein for large volume (approx 75ml) blood draw if veins considered inadequate for apheresis procedure. Some of the blood collected through apheresis may be stored for future studies of HIV disease and immune function and for HLA testing, a genetic test of markers of the immune system.

Fabry Disease Registry & Pregnancy Sub-registry

Fabry Disease

The Fabry Registry is an ongoing, international multi-center, strictly observational program that tracks the routine clinical outcomes for patients with Fabry disease, irrespective of treatment status. No experimental intervention is involved; patients in the Registry undergo clinical assessments and receive care as determined by the patient's treating physician. The primary objectives of the Registry are: * To enhance the understanding of the variability, progression, and natural history of Fabry disease, including heterozygous females with the disease; * To assist the Fabry medical community with the development of recommendations for monitoring patients and reports on patient outcomes to help optimize patient care; * To characterize and describe the Fabry population as a whole; * To evaluate the long-term safety and effectiveness of Fabrazyme® Fabry Pregnancy Sub-registry: This Sub-registry is a multicenter, international, longitudinal, observational, and voluntary program designed to track pregnancy outcomes for any pregnant woman enrolled in the Fabry Registry, regardless of whether she is receiving disease-specific therapy (such as enzyme replacement therapy with agalsidase beta) and irrespective of the commercial product with which she may be treated. Data from the Sub-registry are also used to fulfill various global regulatory requirements, to support product development/reimbursement, and for other research and non-research-related purposes. No experimental intervention is given; thus a patient will undergo clinical assessments and receive standard of care treatment as determined by the patient's physician. If a patient consents to this Sub-registry, information about the patient's medical and obstetric history, pregnancy, and birth will be collected, and, if a patient consents to data collection for her infant, data on infant growth through month 36 postpartum will be collected.

Collection and Distribution of Blood Components From Healthy Donors for In Vitro Research Use

Blood Donors Research Subjects Apheresis

This protocol is designed to provide a mechanism for the Department of Transfusion Medicine, Clinical Center to collect and process blood components from paid, healthy volunteer donors for distribution to NIH intramural investigators and FDA researchers for in vitro laboratory use. Donors meeting research donor eligibility criteria will be recruited to donate blood and blood components by standard phlebotomy and apheresis techniques. The investigational nature of the studies in which their blood will be used, and the risks and discomforts of the donation process will be carefully explained to the donors, and a signed informed consent document will be obtained. Donors will be compensated according to an established schedule based on the duration and discomfort of the donation. NIH and FDA investigators requesting blood components for research use will be required to submit an electronic (Web-based) memo of request, briefly describing the nature of the research, and providing assurance that samples provided through this protocol will be used solely for in vitro and not for in vivo research. This protocol also provides a detailed schema for careful and frequent laboratory safety monitoring of repeat research apheresis donors. Blood components for research use will be distributed with a unique product number, and the DTM principal and associate investigators will serve as the custodians of the code that links the product with a donor s identity. The nature of the in vitro studies in which the blood and components collected in this study will be used is not the subject of this protocol, and is not possible to describe, since it involves basic investigative efforts in greater than 170 different NIH and FDA laboratories. The intent of this protocol is not to approve the research itself, but to provide adequate and complete informed consent for the donor, and to assure that the education, counseling, and protection of the study subjects (research blood donors) is performed in accordance with IRB, OHSR, OPRR and other applicable Federal regulatory standards...

Natural History, Management, and Genetics of the Hyperimmunoglobulin E Recurrent Infection Syndrome (HIES)

Infections Pneumonia Immune System Diseases STAT3 Transcription Factor +1

The Hyper IgE Syndromes (HIES) are primary immunodeficiencies resulting in eczema and recurrent skin and lung infections. Autosomal dominant Hyper IgE syndrome (AD-HIIES; Job's syndrome) is caused by STAT3 mutations, and is a multi-system disorder with skeletal, vascular, and connective tissue manifestations. Understanding how STAT3 mutations cause these diverse clinical manifestations is critical to our complete understanding of bone metabolism, bronchiectasis, dental maturation, and atherosclerosis. Bi-allelic mutations in DOCK8 cause a combined immunodeficiency previously described as autosomal-recessive Hyper IgE syndrome. These individuals suffer from extensive viral infections as well as have a high incidence of malignancy and mortality. The pathogenesis of this disease and long-term natural history is being investigated. Therefore, we seek to enroll patients and families with a confirmed or suspected diagnosis of HIES syndrome for extensive phenotypic and genotypic study as well as disease management. Patients will be carefully examined by a multidisciplinary team and followed longitudinally. Through these studies we hope to better characterize the clinical presentation of STAT3-mutated HIES, DOCK8 deficiency and other causes of the hyper IgE phenotype, and to be able to identify further genetic etiologies, as well as understand the pathogenesis of HIES. We seek to enroll 300 patients and 300 relatives.

Diagnosis of Pheochromocytoma

Pheochromocytoma Endocrine Disease Endocrine Diseases

The goal of this study is to develop better methods of diagnosis, localization, and treatment for pheochromocytomas. These tumors, which usually arise from the adrenal glands, are often difficult to detect with current methods. Pheochromocytomas release chemicals called catecholamines, causing high blood pressure. Undetected, the tumors can lead to severe medical consequences, including stroke, heart attack and sudden death, in situations that would normally pose little or no risk, such as surgery, general anesthesia or childbirth. Patients with pheochromocytoma may be eligible for this study. Candidates will be screened with a medical history and physical examination, electrocardiogram, and blood and urine tests. Study participants will undergo blood, urine, and imaging tests, described below, to detect pheochromocytoma. If a tumor is found, the patient will be offered surgery. If surgery is not feasible (for example, if there are multiple tumors that cannot be removed), evaluations will continue in follow-up visits. If the tumor cannot be found, the patient will be offered medical treatment and efforts to detect the tumor will continue. Main diagnostic and research tests may include the following: 1. Blood tests - mainly measurements of plasma or urine catecholamines and metanephrines as well as methoxytyramine. If necessary the clonidine suppression test can be carried out. 2. Standard imaging tests - Non-investigational imaging tests include computed tomography (CT), magnetic resonance imaging (MRI), sonography, and 123I-MIBG scintigraphy and FDG (positron emission tomography) PET/CT. These scans may be done before and/or after surgical removal of pheochromocytoma. 3. Research PET scanning is done using an injection of radioactive compounds. Patients may undergo 18F-FDOPA, 18F-DA, as well as 68Ga-DOTATATE PET/CT . Each scan takes up to about 2 hours. 4. Genetic testing - A small blood sample is collected for DNA analysis and other analyses....

Activation and Function of Eosinophils in Conditions With Blood or Tissue Eosinophilia

Immune System Diseases Eosinophilia Helminthiasis Hypersensitivity +1

This study will investigate how, why and under what conditions eosinophils (a type of white blood cell) become activated and will examine their function in immune reactions. Eosinophil counts often rise in response to allergies, asthma, and parasitic worm infections. They can also go up in uncommon autoimmune conditions and, rarely, in association with tumors. Elevated levels of these cells is called eosinophilia. Usually, eosinophilia causes no apparent symptoms, but in rare cases there may be local swelling and itching, allergic lung problems, heart disease or nerve damage caused by the release of toxic substances in these cells into body tissues. Patients 1 to 100 years of age with eosinophil counts greater than 750/ml or an abnormal accumulation of eosinophils in the skin or body tissues may be eligible for this study. All participants will have a thorough medical history, physical examination and blood tests. Depending on the person's age and symptoms, other diagnostic tests may be done, including specialized studies of the eye, lungs, skin, bone marrow, nerves or heart. This is not a treatment study, and no experimental treatments will be offered. Patients who require treatment will receive standard medical care. Certain other procedures may be requested solely for research purposes. All participants will be asked to donate extra blood for laboratory studies investigating how immune cells and other immune substances in the blood act to stimulate a rise in eosinophils. In addition, some participants may undergo one or more of the following: * Annual Follow-up evaluations - Physical examinations and blood tests to evaluate changes in the patient's condition and eosinophil counts over time. * Bone marrow biopsy and aspiration will be recommended during the initial evaluation, and in certain patients at other times when it is important to look directly at the newly developing cells in the bone marrow. For this procedure an area of skin and bone is anesthetized with xylocaine (an anesthetic similar to that used by dentists), and a very sharp needle is used to sample the bone marrow for evaluation. Bone marrow biopsy and aspiration can have side effects of pain and/or bleeding into the skin and soft tissues at the site of the procedure. Rarely the area at the biopsy site can become infected, and is treated with antibiotics. * Genetic testing: Some of the blood drawn from you as part of this study will be used for genetic tests. Genetic tests can help researchers study how health or illness is passed on to you by your parents or from you to your children. Any genetic information collected or discovered about you or your family will be confidential. * Leukapheresis (only patients 18 years and older) to collect large numbers of certain cells - In this procedure, whole blood is collected through a needle placed in an arm vein. The blood circulates through a machine that separates it into its components. The white cells are then removed and the rest of the blood is returned to the body, either through the same needle used to draw the blood or through a second needle placed in the other arm.

This study is designed to evaluate the genetics involved in the development of lung disease by surveying genes involved in the process of breathing and examining the genes in lung cells of patients with lung disease. The study will focus on defining the distribution of abnormal genes responsible for processes directly involved in different diseases affecting the lungs of patients and healthy volunteers. Optional CT Sub-study The standard CT scan will be compared to the low dose radiation CT scan for the 150 subjects enrolled in the sub-study to assess the variation between the two techniques. Specifically, the quantitative computer aided detection of lung CT abnormalities from LAM can be compared to assess whether low radiation dose CT exams is an alternative to conventional CT to monitor disease status. This optional sub-study will be offered to up to 100 adult subjects with lung disease and up to 50 children age 9 and older with CF. Children will not be enrolled in the optional CT sub-study unless they have had a standard CT scan for medical purposes to use in comparison. One additional low dose radiation CT scan of the chest may be done as part of this sub-study when these subjects have their next annual CT scan.

Improved Methods of Cell Selection for Bone Marrow Transplant Alternatives

Graft-Versus-Host Disease Graft-versus-leukemia Donor Apheresis

Bone marrow transplants (BMT) are one form of treatment for disorders of the blood, including leukemia. However, because the procedure is often associated with potentially life-threatening reactions, it is usually reserved for patients with serious illnesses under the age of 60 years old. One serious reaction complicating bone marrow transplants is referred to as graft-versus-host disease (GVHD). GVHD is a potentially fatal incompatibility reaction. The reaction is caused by antigens found on the cells of the patient that are not present on the cells of the donor. The antigens are recognized by transplanted white blood cells (lymphocytes). These lymphocytes begin attacking the recipient s cells and tissues and may lead to death. In order to avoid GVHD, researchers have developed a technique using peripheral blood instead of bone marrow that allows transplantation of stem cells and removal of lymphocytes. Stem cells are the cells responsible for returning blood cell production to normal. Lymphocytes are the white blood cells that can cause GVHD. The technique requires two steps. In the first step blood cells are collected from donors who have received doses of a growth factor. The growth factor (granulocyte colony stimulating factor) is designed to increase the production of donor stem cells. In the second step white blood cell lymphocytes are removed from the collected blood, leaving only the stem cells. The main goal of this study is to develop and improve the method of processing cells that are collected after stimulation with growth factor (G-CSF), by removing the white blood cell lymphocytes which can cause graft-versus-host disease (GVHD) while keeping the stem cells necessary for healthy blood cell building. In addition, researchers are interested in studying whether giving G-CSF has an effect on lymphocyte function, which may influence the immune reactions occurring in bone marrow transplantation. ...

Clinical and Basic Investigations Into Hermansky-Pudlak Syndrome

Hermansky-Pudlak Syndrome (HPS)

Hermansky-Pudlak Syndrome (HPS) is an inherited disease which results in decreased pigmentation (oculocutaneous albinism), bleeding problems due to a platelet abnormality (platelet storage pool defect), and storage of an abnormal fat-protein compound (lysosomal accumulation of ceroid lipofuscin). The disease can cause poor functioning of the lungs, intestine, kidneys, or heart. The major complication of the disease is pulmonary fibrosis and typically causes death in patients ages 40 - 50 years old. The disorder is common in Puerto Rico, where many of the clinical research studies on the disease have been conducted. Neither the full extent of the disease nor the basic cause of the disease is known. There is no known treatment for HPS. The purpose of this study is to perform research into the medical complications of HPS and begin to understand what causes these complications. Researchers will clinically evaluate patients with HPS of all ethnic backgrounds. They will obtain cells, blood components (plasma), and urine for future studies. Genetic tests (mutation analysis) to detect HPS-causing genes will also be conducted.\

Genetic Analysis of Immune Disorders

DOK 8 STAT1 GATA2 Immunodeficiency +1

The purposes of this study are to 1) identify the genes responsible for certain immune disorders, 2) learn about the medical problems they cause, and 3) learn how to predict who is likely to develop these disorders and what the risk is of passing them on to children. The immune system is the body s defense system. Some immune deficiencies impair a person s ability to fight infections; others render a person susceptible to allergies, or to autoimmune diseases such as lupus or arthritis, in which the immune cells (white blood cells) attack and destroy the body s own tissues. Patients with immune disorders known or suspected to have a genetic basis and their family members may enroll in this study. Eligibility will be determined by a review of the patient s medical records and family medical history. Participants will provide a small blood sample for genetic (DNA) and white blood cell analysis. Gene samples (but not white blood cells) may also be obtained by mouth brushing or skin biopsy. For the mouth brushing, a small brush is rubbed against the inside of the cheeks for 1 minute to wipe off some cells. For the skin biopsy, a small circle of skin (about 1/8 inch) is removed under local anesthetic. Pregnant women may be asked to provide a fetal sample (amniotic fluid cells or chorionic villus sample). All samples will be used for immune or genetic studies of the family s immune disorder. If test results show a specific genetic variation responsible for the family s immune disorder, a report will be sent to the patient s doctor or genetic counselor, who will discuss the implications for the family. NIH researchers and genetic counselors will also be available to explain results and answer questions. Information will not be available in the case of disorders that cannot yet be linked to a specific genetic abnormality. Information from this study will increase knowledge about the immune system and what causes immune deficiencies. Participants may also learn the underlying cause of an immune disorder that affects them or someone in their family information may be useful in guiding treatment and in making decisions regarding family planning.
