This study will evaluate patients with abnormal immune function that results in recurrent or unusual infections or chronic inflammation. This may include inherited conditions, such as X-linked severe combined immunodeficiency (XSCID), chronic granulomatous disease (CGD), and leukocyte adhesion deficiency (LAD), or conditions resulting from outside factors, such as graft-versus-host disease (GVHD). The information from this study will be used to establish the pattern and pace of change of the disease and to help develop new treatments. The period of observation and study following enrollment in this study may be for up to one year. In addition these studies may provide the medical information needed to determine eligibility for enrollment in other clinical study protocols and more prolonged follow up. Patients of any age with abnormal immune function who have recurrent or unusual infections, whose blood tests show evidence of immune dysfunction, or who have GVHD, XSCID, CGD or LAD may be eligible for this study. Patients' parents, siblings, grandparents, children, aunts, uncles and first cousins of any age also may be included. Healthy normal volunteers between 18 and 85 years of age are recruited as controls. Normal volunteers undergo a physical examination and provide blood, saliva, and urine samples for immune function studies. Patients' family members provide a medical history, have a physical examination, and give blood and urine samples, and possibly a saliva sample. The samples are used for genetic and routine laboratory studies. Investigators may request tissue samples, such as biopsy specimens, previously removed for medical reasons to be sent to NIH for study. Patients undergo the following tests and procedures: 1. Medical history and physical examination. 2. Blood and urine tests, including analysis for genes involved in immune disorders. 3. Buccal smear (in some patients) for genetic studies. This involves scraping the lining of the mouth near the cheek. 4. Specialized tests to evaluate specific conditions in patients who have an immune disorder that might affect lung function, gum infections or eye problems. These may include chest x-ray, CT scan, breathing function test, dental, eye, and hearing examinations. 5. Follow-up visits of patients with immune problems may occur at 6 months and at one year after the first visit (or more frequently if medically required) to include: - Medical history update - Physical examination - Follow-up on abnormal test results and medical treatments initiated at NIH - Collection of blood, saliva, urine, or wound drainage samples for repeat immune function studies - Tissue study of specimens removed for medical reasons at other institutions besides NIH

Study summary:

This protocol is designed for the screening and baseline assessment of and collection of research sample from patients with abnormalities of immune function as manifested by recurrent or unusual infections, recurrent or chronic inflammation, or previous laboratory evidence of immune dysfunction. Abnormalities of immune function may be inherited or may be iatrogenic such as that following hematopoietic stem cell transplantation or other treatments resulting in prolonged immune dysfunction. Blood and/or bone marrow cells may also be used to investigate the utility of induced pluripotent stem cells (iPS) for immune cell derivation and targeted gene correction. This is not a protocol to study or screen for human immunodeficiency virus infection, though patients with HIV infection who may have other causes for immune dysfunction are not excluded. First or second degree genetically related family members (limited to mother, father, siblings, grandparents, children, aunts, uncles and first cousins of an affected patient) may also be screened for clinical, in vitro and genetic correlates of immune abnormalities. Healthy Volunteers will be enrolled as a source of control blood samples for research testing, not to include genetic testing. Screening and baseline assessment under the auspices of this study may be limited to two visits over one year period, unless the patient has been determined by initial evaluation to require further study at NIH or are ongoing long-term safety assessments as required by their participation on a gene therapy or transplant protocol. Patients with documented immune dysfunction may receive limited medically indicated treatment if that medically indicated treatment is related to the abnormality of immune function under study, with such treatment limited to the period of the one year baseline assessment indicated in this protocol. When screening and assessment is complete, patients will be offered an opportunity to participate in another study, or if there are no active studies appropriate for the patient, other options will be suggested to the primary or referring physician. This protocol will allow detailed investigation of patients with abnormalities of immune function with up to one year of observation with the following goals: 1. To determine the degree, scope and cause of immune dysfunction; 2. To establish the pace and pattern of change in the disease process; 3. To determine the extent of organ involvement and damage from immune dysfunction. This screening and baseline assessment is necessary to discover new causes of immune abnormalities, to delineate epidemiology of immune deficiencies, to develop new diagnostic and therapeutic tools, and to determine a patient's eligibility for other studies. Lung MRI as a CT supplement in Infection Surveillance in Immunodeficiencies: The routine use of computed tomography (CT) has increased substantially since its introduction into medicine, which, in turn, has also increased the amount of radiation to which individuals are exposed. This increased radiation is not without risk and is particularly problematic in our primary immunodeficiency disease population, who require serial imaging with chest CTs to manage pneumonia. Standard medical practice in this patient population is to diagnose infection by obtaining a diagnostic CT and then repeating the CT every three to four weeks until the lesion has resolved in order to guide the treatment course. Although the radiation dose at our institution has been reduced by a factor of four in the last several years as a result of peak kilovoltage (kVp) reduction dose modulation and iterative reconstruction; cumulative radiation exposure carries an increased lifetime risk for cancer and reducing exposure should be in keeping with the mandate, As Low As Reasonably Achievable (ALARA). Magnetic resonance imaging (MRI), which does not expose the patient to any ionizing radiation, has shown promise in detecting the obvious infiltrates secondary to cross sectional ability and increasing resolution. Previously, lung MRI had not been considered as a potential substitute for CT because of poor signal- to- noise ratio (SNR) due to the low density of protons in lung parenchyma, the short T2* relaxation time in the lungs secondary to air-tissue based susceptibility, and the challenge of imaging over long scan times resulting in respiratory, vascular and cardiac motion artifacts. However, the recent development of MRI scanning techniques that provide an ultra short echo time (UTE) along with oversampling of k-space center appear to overcome the above mentioned drawbacks of MRI for imaging the lung/ chest. For this protocol, we will use optimized versions of the MRI UTE pulse sequence on our 3T clinical scanners to perform breath-hold (BH) coronal and BH and free-breathing axial images. Our goal is to comprehensively evaluate the lung without additional radiation with a clinically reasonable scan time of <30 minutes, especially with a proportionally high percentage of young adults. Subjects enrolled under 05-I-0213 with primary immune deficiencies may be considered for participation in the sub study to evaluate the feasibility of novel MRI techniques compared with standard CT imaging for pathology surveillance if they are undergoing medically indicated CT imaging for the diagnosis or monitoring of infection.
