Filter by:This study was to evaluate the efficacy and safety of Tacrolimus combined with entecavir antiviral therapy for HBV-associated glomerulonephritis in china. Tacrolimus combined with entecavir rapidly and effectively induced remission of HBV-GN in Chinese adults. Meanwhile, Tacrolimus may have a synergistic antiviral effect with entecavir. The study protocol was reviewed and approved by Guangdong General Hospital's Ethic Committee, and all participants provided written informed consents. The study will be a prospective, randomized,controlled,single-blind, multi-centre, withdrawal study conducted by Guangdong general hospital, Guangdong Academy of Medical Sciences.there will be two phases, phase 1, Screening and enrolling 112 HBV-GN patients about one year,and phase 2, ongoing follow-up for 24 weeks.The data of all patients will be recorded in the HBV-GN electronic database.Before the randomisation, All patients will receive entecavir routine antiviral therapy for two weeks.And then they will be randomized to two different group,the treatment group: Tacrolimus combined with entecavir antiviral therapy,the control group: The Tacrolimus placebo and entecavir antiviral therapy. The Tacrolimus target trough concentration was 5-10 ng/mL during the therapy. The primary outcome variables were the number of patients who reached complete or partial remission (CR or PR) after the 25 week-treatment. CR was deļ¬ned as <0.3 g/24 h proteinuria (UPCR<300mg/g.cr) or lower plus stable renal function (eGFR>50 ml/min/1.73 m2) and PR as proteinuria 0.3-3.0 g/24 h (UPCR 300-3000mg/g.cr) and 50% lower than baseline proteinuria plus stable renal function. Secondary outcome variables: 1) The number of patients who reached complete or partial remission (CR or PR) after the 13 week-treatment. 2) Serum creatinine (SCr) increased 2 times the baseline levels or 50% lower than the baseline eGFR(according to chronic kidney disease-EPI (CKD-EPI) )after the 25 week-treatment. 3)Serum HBV DNA was undetectable(HBV DNA<500copies/ml) at the end of 25 week-treatment. 4) The number of patients who present acute kidney injury at the end of 25 week-treatment.
The investigators are registering all nephrotic syndrome (NS) patients regardless of the primary causes and developing a NS database in China. Patients will be followed-up and both baseline and follow-up information will be recorded in the registration system. The treatment response, longitudinal changes of renal function, renal survival, patient survival, infection events and acute kidney injury etc, will be analyzed using the NS database.
The trial investigates the use of VPA (Valproic Acid) for the treatment of adult patients with biopsy proven idiopathic focal segmentel glomerulosclerosis (FSGS) or minimal change disease (MCD). VPA used as an add-on to steroids might induce clinical remission in a first category of patients and potentially reduce the dose of maintenance immunosuppression required to maintain remission thereafter. In a second category of patients VPA might allow the reduction or even cessation of immunosuppression while clinical remission is maintained.
Idiopathic Focal Segmental Glumero Sclerosis (FSGS) is not very common but important manifestation of kidney disease. FSGS has poor prognosis among the patterns of Idiopathic Nephrotic Syndrome (INS). Even with treatment (Steroid therapy and cytotoxic immunosuppressant therapy), many patients eventually still require dialysis. Cell therapy is useful in treatment of INS and mesenchymal stromal/stem cell is one of the cells that useful in the treatment of glomerulus disease. Intravenous injection of allogeneic adipose derived mesenchymal stromal/stem cell will be done in 5 patients with refractory INS(FSGS). They will be followed 1, 2, 4 weeks and then monthly until a year following injection day.
The vast majority of children with idiopathic nephrotic syndrome respond well to corticosteroid treatment. However, as many as 20% experience a more complicated course with steroid resistance (SRNS). Repeated and prolonged courses of steroids in these children often result in long-term complications. The goal of treatment is to reduce the rate of relapses, the cumulative dose of corticosteroids, and the incidence of serious complications. In order to minimize the side effects of steroid therapy, different steroid sparing agents such as cyclophosphamide, calcineurin inhibitors(CNI), levamisole, and mycophenolate mofetil (MMF) have been used in SRNS. Whereas CNI are usually considered the steroid sparing drug class of first choice, rituximab is increasingly used as alternative to minimize CNI toxicity. Various prospective studies suggest that Rituximab, a B cell depleting monoclonal antibody, could be a safe and effective alternative to steroid or immunosuppressants to achieve and maintain remission in this population. Rituximab infusion have been shown to be efficacious for 6 to 12 months and the side effect profile observed to date is very benign. Studies comparing the usefulness of these agents are lacking. In this proposed randomized controlled trial, the investigators want to compare the efficacy and safety of CNI to that of Rituximab in treating children with SRNS.
Anti-CD20 agent has been proposed as a rescue therapy for refractory nephrotic syndrome(NS) on the basis of favorable clinical observations. Yet the long-term effect on maintaining remission or the likelihood of becoming rituximab-dependent is unclear and the information on the safety profile of rituximab is limited. This trial was designed to investigate the safety and efficacy of Rituximab in children with refractory NS.
INSIGHT is a longitudinal study of childhood nephrotic syndrome to determine genetic, serologic and environmental factors contributing to nephrotic syndrome and disease progression.
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.
Minimal change disease (MCD), focal segmental glomerulosclerosis (FSGS), and Membranous nephropathy (MN), generate an enormous individual and societal financial burden, accounting for approximately 12% of prevalent end stage renal disease (ESRD) cases (2005) at an annual cost in the US of more than $3 billion. However, the clinical classification of these diseases is widely believed to be inadequate by the scientific community. Given the poor understanding of MCD/FSGS and MN biology, it is not surprising that the available therapies are imperfect. The therapies lack a clear biological basis, and as many families have experienced, they are often not beneficial, and in fact may be significantly toxic. Given these observations, it is essential that research be conducted that address these serious obstacles to effectively caring for patients. In response to a request for applications by the National Institutes of Health, Office of Rare Diseases (NIH, ORD) for the creation of Rare Disease Clinical Research Consortia, a number of affiliated universities joined together with The NephCure Foundation the NIDDK, the ORDR, and the University of Michigan in collaboration towards the establishment of a Nephrotic Syndrome (NS) Rare Diseases Clinical Research Consortium. Through this consortium the investigators hope to understand the fundamental biology of these rare diseases and aim to bank long-term observational data and corresponding biological specimens for researchers to access and further enrich.
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.
