Filter by:Researchers from the University of Michigan and Northwestern University are studying people's experiences with swelling caused by Nephrotic Syndrome. Interviews with patients (child and adult) and parents of young children will be conducted. The information collected from the interviews will be used to develop a survey to use when testing new medications for Nephrotic Syndrome. Please consider participating in a 1-hour long interview with the Prepare-NS research study to discuss children and adults experiences with swelling.
The aim of the study is to assess the influence of high doses of intravenous corticosteroids on plasma inflammation and bone markers in patients with primary glomerular disease. The study would include 40 patients with chronic kidney disease. The main inclusion criterion is clinical and histopathological diagnosis of primary glomerular disease and urine protein excretion >2.0 g/24h. The exclusion criteria include secondary glomerular disease, acute kidney injury, acute or chronic inflammation, history of non-compliance.
The major objective is to demonstrate the safety and efficacy of ANG-3070 in patients with primary glomerular disease and persistent proteinuria.
The primary objectives of this study are to: (1) determine the impact of glomerular disease on bone strength and (2) investigate the pathophysiologic underpinnings of impaired bone strength in glomerular disease.
The investigators will attempt to develop a more accurate equation to estimate eGFR in pediatric and adult sickle cell patients
Glomerulonephritis (GN) generates an enormous individual and social economic burden. However, the therapeutic options are largely based on clinical and pathological parameters and the individual response to therapy or prognosis is uncertain. Recently, along with advances in molecular analysis and computational bioinformatics, genomic data from human renal biopsies could provide a strong foundation for the future of precision medicine in nephrology. In response to a request for applications by the Ministry of Health and Welfare of Korea for the creation of Clinical Research Registry, multi-center N network has been established for prospective cohort with kidney biopsy samples (KORNERSTONE). Through this Network the investigators hope to understand the fundamental biology of glomerulonephritis and aim to bank long-term observational data and corresponding biological data including genomic data from kidney tissues, and kidney pathologic data which is digitalized This database is archived to a web-based platform to access easily and further enrich for researchers.
Background: - The Nephrotic Syndrome Study Network (NEPTUNE) is a network of multidisciplinary researchers who are investigating why kidney disease happens. NEPTUNE researchers will collect kidney tissue and other samples (for example, blood and urine) from individuals who are scheduled to have kidney biopsies to determine the cause of protein in the urine (only one kidney biopsy is necessary). Objectives: - To collect kidney tissue, other samples, and data /information for continuing research into kidney diseases. Eligibility: - Individuals at least 18 years of age who need to have a kidney biopsy to determine the cause of protein in the urine, do not have a systemic disease that is the cause of the their kidney disease, and have not received specific treatment for kidney disease. Design: - This study involves a screening and baseline visit and additional followup visits after the kidney biopsy. - Participants will be screened with a medical history and physical examination, as well as blood and urine samples and collection of fingernail clippings. Participants will also complete questionnaires about their history of kidney problems. - During the kidney biopsy, performed at the NIH Clinical Center, researchers will take an additional tissue sample for research. - Participants will return for followup visits at NIH every 4 months in the first year, and every 6 months in the second through fifth years after the biopsy. Additional blood and urine samples will be collected at each visit, and fingernail clippings will also be collected annually by the study researchers. - Treatment for kidney disease will not be provided as part of this protocol and instead will generally be provided by the patient s own physician. Compensation: Subjects received compensation for each visit to the NIH Clinical Center.
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.
