Filter by:This is an exploratory natural history protocol that will enroll patients with known genetic diseases, such as VEXAS syndrome, or as yet undiagnosed disorders of inflammation with the goal of improving our understanding of disease processes. Blood, saliva, hair, nail, or buccal samples may be collected for genetic analysis, blood samples will be obtained for immunologic and other functional studies, and a small number of subjects may undergo skin biopsy.
This study learn how easily patients can use an educational tool that will be created for patients with melanoma and pre-existing autoimmune diseases who receive or will receive immune checkpoint inhibitor drugs. Patients will be asked their opinions about the design, accessibility, and content of the tool. Researchers will use the information collected to improve the educational materials that will help patients make future decisions about their treatment.
This phase Ib trial studies the side effects of nivolumab and to see how well it works in treating patients with autoimmune disorders and cancer that has spread to other places in the body or cannot removed by surgery. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
This study is an open-label randomized controlled trial aiming to investigate whether the efficacy and side effect of Leflunpomide plus glucocorticoid.
This is an open-label randomized controlled trial to compare the efficacy of Prednisone alone and combination therapy of Prednisone and Mycophenolate mofetil in IgG4RD patients.
This is an open-label study to investigate the diagnostic performance of 18F-FDG PET/CT (positron emission tomography/computed tomography) in evaluation of patients with IgG4-related disease. A single dose of 18F-FDG will be intravenously injected into patients with IgG4-related disease before and after treatment.
The purpose of this study is to collect DNA samples from patients undergoing routine care at the University of Chicago. These samples will be tested for differences in genes that may suggest greater risk of side effects or chance of increased benefit from certain medications. The results will be made available to the patient's treating physician and the researchers will track whether or not this information is used in routine health care.
Background: - Membranous nephropathy is associated with damage to the walls of the glomeruli, the small blood vessels in the kidneys that filter waste products from the blood. This damage causes leakage of blood proteins into the urine and is associated with low blood protein levels, high blood cholesterol values, and swelling of the legs. These problems can decrease or go away without treatment in about 25 percent of patients, but if they persist, some patients may experience impaired (or loss of) kidney function, blood vessel and heart disease, and a risk of forming blood clots in veins. - Kidney biopsies that show that antibodies have been deposited along the glomeruli suggest that specialized cells of the immune system, called B and T cells, are causing damage to the kidneys through their increased activity. To suppress the action of B and T cells and to decrease the harmful deposits in the kidneys, drug treatments are required. - Patients with membranous nephropathy are often treated with immunosuppressive drugs such as cyclosporine or cytoxan plus steroids that attempt to reduce or suppress the activity of the immune system, decrease antibody production, and reduce antibody deposits in the kidney. However, not everyone responds to these medications and the kidney disease can return in some patients when the drugs are stopped. Also, there are side effects associated with long term usage of these medications. Rituximab, a different immunosuppressant, has also been used for this purpose. Although cyclosporine and Rituximab have been used separately, they have not been tried in combination as a possible treatment for membranous nephropathy. Objectives: - To determine the safety and effectiveness of combining rituximab and cyclosporine to treat membranous nephropathy. Eligibility: - Individuals 18 years of age and older who have been diagnosed with membranous nephropathy based on a kidney biopsy done within the preceding 24 months, and who have had excess levels of protein in the urine for at least 6 months based on urine and blood tests. Design: - Potential participants will be screened with an initial clinic evaluation and full medical history. - Before the treatment, there will be a run-in period that will last up to 2 months. During this time, participants will be placed on a blood pressure lowering medication and will not take any other immunosuppressant medications. - Participants will visit the NIH clinical center for a baseline evaluation, four intravenous infusions of rituximab, and also at 1- to 6-month intervals throughout the study. - Active treatment period will involve a 6-month course of cyclosporine and a total of four doses of rituximab. Participants will take cyclosporine tablets twice daily, and have two infusions of rituximab given 2 weeks apart, After 6 months, the cyclosporine dose will slowly be decreased over several weeks and then completely discontinued. Participants will then receive another course (two doses 2 weeks apart) of rituximab, depending on results of blood work. - Participants will have frequent blood and urine tests performed to monitor the results of treatment and reduce the chance of side effects.
Background: - Bronchiectasis is a disease characterized by airways that are inflamed, abnormally dilated, and chronically infected. Individuals with bronchiectasis have a history of chronic and recurring respiratory infections. Depending on the underlying cause, these infections may involve the entire respiratory tract, resulting in sinus, ear, and lung disease. - Bronchiectasis continues to be a significant problem in developing countries and in specific groups of individuals, particularly in people who have cystic fibrosis. Although treatments are available or under development for bronchiectasis related to cystic fibrosis, many of the disease-specific treatments may not be effective for bronchiectasis not related to cystic fibrosis. Objectives: - To study the natural history of bronchiectasis to identify inherited and immune factors that may explain why certain individuals have chronic recurring infections. Eligibility: - Individuals 5 years of age and older who have an established diagnosis of bronchiectasis or a history of chronic/recurring respiratory infections. - Direct family members (e.g., parents, siblings, children) of patients in the study may also be asked to participate. Design: - Potential participants will be screened with an initial clinic evaluation and full medical history, as well as a general quality of life and respiratory symptom questionnaire. - The following standard procedures may be done as part of the study: air sampling from the nose; imaging studies, which may include an x-ray or computed tomography (CT), lung function tests; and collection of samples of blood, urine, and sputum (phlegm or mucus). Other tests may be performed as required by the researchers, and will be explained to patients as needed. - Both patients and relatives (if asked to participate) will provide the following samples: blood or buccal (cheek swab) cells for genetic testing, sputum, and urine. - To prevent infections and potential disease progression, patients may receive standard medical care and treatment for bronchiectasis and related infections during this protocol.
