Background: Lung transplants can save lives, but the procedure has risks. Some people develop donor-specific antibodies (DSA) after the procedure-that is, their bodies create proteins that treat the new lungs as foreign and mount an immune response against them. This is called rejection. But not everyone who has a transplant develops DSA, and not everyone who has DSA develops rejection. Researchers want to understand why. Objective: To collect data to try to find out why some people develop rejection after lung transplants while others do not. Eligibility: People aged 18 to 75 years who have progressive lung disease or undergone or may undergo a lung transplant. Design: Participants will have clinic visits every 3 to 6 months for up to 4 years. Some visits might require an overnight stay. Each visit will include multiple tests and procedures: Physical exam with blood and urine tests. Some blood will be used for genetic testing. Imaging scans.

Background: Blood cancers (such as leukemias or lymphomas) often do not respond to standard treatments. A transplant of blood stem cells from a healthy donor can help people with these cancers. Sometimes these transplants cause serious side effects, including a common immunologic problem called graft-versus-host disease. A drug called cyclophosphamide given early after the transplant (post-transplantation cyclophosphamide, PTCy) can reduce these complications. But sometimes this drug has its own negative effects. Furthermore, studies in mice suggest that an intermediate, rather than very high, dose of this drug may best protect against graft-versus-host disease. Objective: To find out if a lower dose of PTCy is more helpful for people who undergo blood stem cell transplants. Eligibility: People aged 18 and older who have a blood cancer and are eligible for a transplant of blood stem cells from another person. Healthy donors are also needed but must be related to the individual needing the transplant. Design: Participants will undergo screening. Transplant recipients will have imaging scans and tests of their heart and lung function. They will be assessed for the status of their cancer, including bone marrow taken from their pelvis and possibly also scans and/or fluid drawn from the spine depending on the disease type. Donors will be screened for general health. They will give several tubes of blood. They will give an oral swab and saliva and stool samples for research. Recipients will be in the hospital at least 4 to 6 weeks. They will have a temporary catheter inserted into a vein in the chest or neck. Medications will be given and blood will be drawn through the catheter. The transplanted stem cells will be given through the catheter. Participants will receive medications both before and after the transplant. Participants will return to the clinic at least once a week for 3 months after leaving the hospital. Follow-up visits will continue periodically for 5 years.

Without an explanation for severe and sometimes life-threatening symptoms, patients and their families are left in a state of unknown. Many individuals find themselves being passed from physician to physician, undergoing countless and often repetitive tests in the hopes of finding answers and insight about what the future may hold. This long and arduous journey to find a diagnosis does not end for many patients- the Office of Rare Diseases Research (ORDR) notes that 6% of individuals seeking their assistance have an undiagnosed disorder. In 2008, the National Institutes of Health (NIH) Undiagnosed Diseases Program (UDP) was established with the goal of providing care and answers for these individuals with mysterious conditions who have long eluded diagnosis. The NIH UDP is a joint venture of the NIH ORDR, the National Human Genome Research Institute Intramural Research Program (NHGRI-IRP), and the NIH Clinical Research Center (CRC) (1-3). The goals of the NIH UDP are to: (1) provide answers for patients with undiagnosed diseases; (2) generate new knowledge about disease mechanisms; (3) assess the application of new approaches to phenotyping and the use of genomic technologies; and (4) identify potential therapeutic targets, if possible. To date, the UDP has evaluated 3300 medical records and admitted 750 individuals with rare and undiagnosed conditions to the NIH Clinical Center. The NIH UDP has identified more than 70 rare disease diagnoses and several new conditions. The success of the NIH UDP prompted the NIH Common Fund to support the establishment of a network of medical research centers, the Undiagnosed Diseases Network (UDN), for fiscal years 2013-2020. The clinical sites will perform extensive phenotyping, genetic analyses, and functional studies of potential disease-causing variants. The testing performed on patients involves medically indicated studies intended to help reach a diagnosis, as well as research investigations that include a skin biopsy, blood draws, and DNA analysis. In addition, the UDN will further the goals of the UDP by permitting the sharing of personally identifiable phenotypic and genotypic information within the network. By sharing participant information and encouraging collaboration, the UDN hopes to improve the understanding of rare conditions and advance the diagnostic process and care for individuals with undiagnosed diseases.

Human phagocytic cells such as polymorphonuclear leukocytes (PMNs) are readily mobilized to sites of infection and ingest microorganisms by a process known as phagocytosis. The combined effects of reactive oxygen species (ROS) and proteolytic peptides and enzymes released into forming bacterial phagosomes kill most ingested bacteria. However, many human bacterial pathogens have devised means to subvert normal phagocyte responses and the innate immune response and cause severe disease. The overall objective of this study is to elucidate specific features of pathogen-phagocyte interactions that underlie evasion of the innate immune response or contribute to the pathophysiology of disease or inflammatory disorders. Therefore, specific projects will: 1. Identify and characterize specific mechanisms used by pathogenic microorganisms to evade or subvert normal phagocyte responses and therefore cause disease. 2. Investigate phagocyte response mechanisms to specific pathogenic microorganisms. 3. Identify specific bacterial structures and/or (gene) products that dictate differences in phagocyte responses among a range of pathogens so that generalized statements can be made about the pathophysiology of disease states. The studies will be performed using multiple techniques including state-of-the-art equipment for genomics and proteomics strategies to identify target bacterial genes/proteins of interest or those up-regulated in phagocytes. Phagocyte-pathogen interactions will be examined using fluorescence-based real-time assays and video microscopy, confocal and electron microscopy in combination with enzymatic assays for ROS production, routine biochemistry, immunology and cell biology. Implementing these studies will require isolation of phagocytic leukocytes from venous blood of healthy human volunteers. The study population will be all-inclusive except in certain instances where individuals possess genetic defects that impair phagocyte function (e.g., myeloperoxidase-deficiency) or have altered phagocyte function due to outside influences such as recent bacterial or viral infection. The proposed studies will likely provide new information pertinent to understanding host cell-pathogen interactions and the pathophysiology of inflammatory conditions....

This study will investigate how genetic and environmental factors contribute to the development of melanoma, a type of skin cancer, and related conditions. Individuals >=4 weeks with a personal or family history of melanoma or atypical spitzoid/Spitz tumor may be eligible for this study. Participants will: - Fill out one or two questionnaires about their personal and family medical history. - Provide written consent for researchers to review their medical records and pathology materials related to their care and those of deceased relatives with melanomas, tumors, cancer, or other related illnesses for whom they are the next-of-kin or legally authorized representative. - Donate a blood or cheek cell sample to be used for genetic studies. (The blood sample is collected through a needle in an arm vein. The cheek cell sample is obtained either by gently brushing the inside of the mouth with a soft brush or by swishing a tablespoon of mouthwash and then spitting it into a container.) - Undergo a skin biopsy (removal of a small piece of skin tissue) for genetic study. For this procedure, the area of skin to be removed is numbed with a local anesthetic and a 1/4-inch piece of skin is excised with a cookie cutter-like instrument. The wound is then covered with a band-aid. Participants may be asked to travel to the NIH Clinical Center for evaluation, including a medical history, physical examination, and some of the following procedures: - Full body skin examination to evaluate the type and number of moles and document any evidence of sun damage to the skin. The examination involves all the skin from the scalp to the bottoms of the feet. After the examination, a medical photographer will photograph the skin, with close-ups of skin lesions marked by the examiner. If there are parts of the skin the participant does not want examined or photographed, he or she can tell the examiner. - Blood draw of about 120 milliliters (4 ounces) or less - Skin biopsy - Cheek cell sample - X-rays, ultrasound and magnetic resonance imaging (MRI) studies to detect tumors or changes in tumors or other types of changes in specific tissues. MRI is a diagnostic test that uses strong magnetic fields and radiowaves to examine body tissues. The subject lies on a table that is moved into a large tunnel-like machine (the scanner) for about 45 minutes to 1 hour. When the tests are finished, a doctor will discuss the results with the participant and the need, if any, for clinical follow-up.

Background: - The blood-brain barrier separates the brain from the rest of the body. Epilepsy is a neurological disease that causes seizures. It can affect this barrier. Researchers think a contrast agent called mangafodipir might be better able to show areas of the brain that epilepsy affects. Objective: - To see if mangafodipir is well tolerated and safe. To see if magnetic resonance imaging (MRI) using either mangafodipir or gadolinium can show areas of blood-brain barrier breakdown in people with epilepsy. Eligibility: - People ages 18-60 who: - Have epilepsy not controlled by drugs - Prior or concurrent enrollment in 18-N-0066 is required Design: - Participants will be screened with: - Medical history - Physical exam - Blood and urine tests - Participants will have up to 6 visits in 1-3 months. One visit is an inpatient stay lasting 2-10 days. Visits may include: - Video-EEG monitoring for participants with epilepsy - An IV catheter put in place: a needle guides a thin plastic tube into an arm vein. - Getting mangafodipir through the IV. - Getting gadolinium through the IV. - Up to 6 MRI scans over a 10-day period: a magnetic field and radio waves take pictures of the brain. Participants lie on a table that slides into a metal cylinder. They are in the cylinder for 45-90 minutes, lying still for up to 10 minutes at a time. The scanner makes loud knocking sounds. Participants will get earplugs. - A final MRI at least 2 weeks after receiving mangafodipir.

Studies performed under 89-N-0045 are designed to examine the natural history of multiple sclerosis (MS) using MRI and immunological measures. In addition to studying the natural history of untreated patients, the natural history of patients receiving approved disease-modifying therapies of MS will be examined. In both cohorts of patients levels of disease activity on MRI will be compared with immunological characteristics in order to help identify disease mechanism. Patients with either definite MS (based either on clinical or combined clinical and MRI criteria) or with an initial presentation of neurological dysfunction consistent with MS will be studied longitudinally by MRI. Disease activity on MRI will be assessed using several MRI measures of disease activity including the number of contrast enhancing lesions, the overall burden of disease, brain atrophy and measures to assess axonal damage. Patients will be assessed clinically and correlations between immunological and genetic factors and disease activity as seen clinically or by MRI will be studied. A second cohort of patients starting the use of approved therapy will also be examined. Patients referred to NIH prior to beginning approved therapy will be assessed with a series of three monthly MRIs to determine the level of pretreatment disease activity. After beginning approved therapy under the direction of their private physician, patients will be followed similarly to the natural history cohort. Immunological and genetic findings will be accessed before and during therapy in order to help establish the mechanisms of action of the therapies and to identify mechanisms accounting for either a response or lack of response to therapy. Part of the collected samples willl be cryopreserved to provide respository for further studies focusing on detection of biomarkers indicative of disease state, disease stage or repsonse to therapies. Additionally, a cohort of normal volunteers will be studied. The studies in the normal volunteers will be used to establish the most appropriate imaging sequences for studying normal white matter in MS patients using magnetization transfer (MT) imaging sequences for studying normal white matter in MS patients using magnetization transfer (MT) imaging and to provide normative immunological measures.

Background: Lung cancer is the leading cause of cancer-related death worldwide. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. Surgery to remove the tumors is the standard treatment for people diagnosed with early stages of NSCLC. Despite complete removal of these tumors, many recur (happen again). An FDA-approved drug combination to treat early-stage NSCLC prior to the surgery is durvalumab plus standard chemotherapy. The FDA approved infusion drug azacytidine [AZA] is used to treat several diseases because it can rapidly kill dividing cells (including cancer cells) but it is not approved for NSCLC. An inhaled (aerosolized) form of AZA is also not approved for NSCLC. However, researchers want to know if an inhaled version of AZA can help improve treatment of people with NSCLC because inhaled AZA goes directly into the lungs with limited absorption into the bloodstream. Objective: To find the safest and most effective dose of inhaled AZA in participants with early-stage non-small cell lung cancer (NSCLC) that can still be removed by surgery. Eligibility: Adults aged 18 and older with operable early-stage NSCLC. Participants will be required to also enroll in NIH protocol 06C0014 which allows for pre- and post-treatment biopsies and bloodwork to be obtained for additional research studies. Design: Participants will be screened. They will have a physical exam with blood tests. Their medical records will be reviewed. They will have imaging scans and tests of their heart and lung functions. Participants will be required to have a tissue sample (biopsy) taken of their tumor prior to receiving study drug and again during surgery after Cycle 3; airway tissue biopsies and collection of collect bronchial (lung) fluid may also be done. Participants will receive the study treatment for 3 cycles. Each cycle is 21 days. They will need to come to the NIH Clinical Center (CC) on days 1-4 of Cycles 1-3. AZA will be given as a drug mist that can be inhaled (like the type of mist in an asthma inhaler) using a nebulizer at the NIH Clinical Center (CC) for 3 days in a row (consecutive days) during the first week of each cycle. The participant will inhale the AZA drug mist for 20 to 30 minutes each time. Participants will also receive durvalumab and a specific 2-drug assigned chemotherapy by intravenous (IV) infusion on day 4 of each cycle. Participants will have a follow-up visit 2 weeks after their last dose of study drugs. Then they will have planned surgery to remove the tumors. Participants will have additional follow-up visits at the NIH CC about 1 and 3 months after the surgery, and then for every 3 months for up to 3 years. ...

Background: Medical advances have improved survival rates for many cancers and other illnesses. This means that more people are coping with the long-term effects of these treatments. Some treatments can cause female infertility. Ovarian tissue cryopreservation (OTC) may help. Before undergoing a treatment that may damage their fertility, patients may opt to freeze a sample of ovarian tissue. The tissue contains immature egg cells. When thawed, the tissue can be reimplanted. This procedure can help women become pregnant. Objective: This natural history study will create a databank of ovarian tissue. The NIH will provide OTC as a clinical service. The NIH will also request a portion of the tissue to use for research. Eligibility: Females aged 4 to 35 who opt to have OTC before receiving cancer treatment. Design: Participants will be screened. Their existing medical records will be reviewed. They will be asked if they want to donate a portion of their ovarian tissue for research. No more than 20% of the tissue collected will be taken for research. Some other tissues that would otherwise be discarded will also be kept. Medical data from each participant may also be collected and stored in the database. This data may include results of routine blood tests, imaging tests, and other information. The data will be coded for privacy. Participants will answer a questionnaire. They will be asked about their fertility treatment and general health. The survey takes about 30 minutes. They will repeat the questionnaire once a year for 30 years.

Background: Multiple sclerosis (MS) is a disease that damages the central nervous system (brain and spinal cord). This leads to increased physical disability over time. The disease is lifelong once it begins. Researchers want to learn more about MS s stages and follow them until a person s death. Objective: To understand how the physical and clinical signs of MS relate to its changes over time. Eligibility: Adults age 18 or older with MS or a disease of the brain and spinal cord that may act like MS. Design: Participants will have a medical history and a complete neurological exam. They may have timed tests of neurological function, such as a 25-foot walk and a 9-hole peg test. Participants will have multi-day visits about once a year. Participants will have blood drawn. Participants may have a brain magnetic resonance imaging (MRI) scan. They may also have an MRI of the spinal cord. They may get a contrast agent (dye) injected into a tube in an arm vein. During the MRI, participants will lie on a table that slides in and out of a metal cylinder. Participants will have the thickness of their retina measured using optical coherence tomography. A camera on top of a table uses lasers. Participants will look through a lens and follow instructions. Eye drops may be used to dilate the pupils. Participants will chew on a piece of sterile cotton for 1 minute to collect saliva. Participants agree to have an autopsy at the time of their death and to donate some of their organs to research, such as the brain and spinal cord.

Background: - Chromatin is is the structural building block of a chromosome. It is found inside the nucleus of the cell and consists of a complex of DNA and protein. - Cancers of the lung, pleura (lung lining) and esophagus show profound changes in chromatin structure that may affect the course of disease in patients. - A better understanding of these diseases and the genetic changes associated with them may be helpful in developing new treatments for them. Objectives: - To evaluate people with cancer of the lung, pleura or esophagus for participation in NCI clinical trials. - To obtain biopsies (small pieces of tissue) from tumor, normal tissue and blood samples to learn more about the cellular changes in blood and tissue in tumors of the lung, esophagus and pleura and surrounding structures in the chest. Eligibility: Patients 2 years of age and older with cancer of the lung, esophagus, pleura, mediastinum or chest wall, or cancers of other origin that have invaded the lung. Note: Patients >= 2 years of age and under 18 years of age may only participate in research sample collection. Design: - Up to 1310 patients may be included in this study. - Patients undergo standard tests for evaluating the stage of their disease and for determining eligibility for an NCI investigational treatment study. - All patients undergo bronchoscopy and bronchoalveolar lavage ("washing" with salt water) to assess their tumor and collect a sample of normal tissue. Patients whose tumor is located on the outside portion of the lung may also undergo thoracoscopy to obtain a tumor sample. For bronchoscopy and bronchoalveolar lavage a tube with a light is passed through the nose or mouth into the lungs to examine the airways. Salt water is injected through the tube and then withdrawn to obtain cells for laboratory studies. For the thoracoscopy a small tube with a light is put through a small hole in the chest to obtain the tumor sample. Both procedures are usually done under general anesthesia. The tissue is examined to identify cell characteristics of people who respond to certain therapies and to identify markers on the surface of the tissue that may be useful in future research and treatment. - Blood and urine samples are collected from patients. - Patients who are eligible for a treatment study at NCI are offered participation in the study. - Patients for whom standard surgery, radiation or chemotherapy is more appropriate may receive treatment at NCI or with their own physician. - Patients who receive treatment at NCI return for follow-up examinations 4 weeks after discharge and then every 2 to 4 months depending on the nature of their cancer.

Objective: To screen and create a list of adult volunteers in good health for participation in research studies conducted at the National Institutes of Health (NIH) in Bethesda, Maryland. Develop a normative set of structural and functional brain MRI scans that are linked to healthy research volunteer characteristics. Maximize scientific impact of data from volunteers by broadly sharing with other researchers. Study Population: Adult males and females in general good health who are 18 years of age and older. Design: Adult individuals who are interested in participating in NIMH IRP clinical studies as a healthy research volunteer can directly visit or be directed to visit the study website where they will first consent electronically and then complete a set of online self-report measures. Items may include: demographic information, mental health symptoms, disability status, substance use patterns, handedness and clinical/family history. Individuals who are flagged based on predetermined responses to survey items will be further screened by a member of the study clinical team. If found to be ineligible for the study because of a clinically significant or unstable medical or mental health condition, these individuals will be referred back to the community and/or given information about NIMH clinical studies for which they may be eligible. Respondents with no flags or who pass through additional screening will be scheduled for an in-person assessment. During the outpatient appointment and after in-person informed consent, participants will receive a brief clinical interview to screen for current medical and mental conditions, and risk for self-harm. They will complete assessments of psychological, emotional, physiologic, biological and cognitive functioning. Participants will undergo a physical exam and be asked to provide blood and urine samples for routine clinical labs. Participants can separately consent for an optional baseline brain magnetic resonance imaging (MRI) scan and an optional magnetoencephalography (MEG) exam. All consent forms will explicitly inform participants that if enrolled in the study, their de-identified data will be broadly and publicly shared through NIH-approved data repositories. Participants in this recruitment and characterization study will then be placed on a list of healthy research volunteers from which other NIMH IRP studies may recruit according to the inclusion and exclusion criteria in their respective IRB-approved protocols. Outcome Measures: Outcome measures may include demographic data, mental and medical history and symptoms, results of psychological, emotional, physiologic, biological, and cognitive testing, physical exam and MRI findings....
