Filter by:We propose to study the use of purified porcine Acthar Gel (ACTHAR, Mallinckrodt Pharmaceuticals) for treatment of steroid resistance nephrotic syndrome (SRNS) in a prospective pilot study. We plan to enroll 25 children between the ages of 2 to 21 years. Children fulfilling strict inclusion criteria, whose parents agree to written informed consent after institutional IRB approval for the study, will be enrolled. Purified porcine Acthar Gel will be administered SQ to all children using a defined treatment protocol for a period of six months. Renal function, urine protein excretion, serum albumin levels, blood pressure and growth parameters will be monitored closely on all patients. Baseline urine protein excretion will be compared to end of treatment levels to determine successful response to therapy. There will be an 18 month enrollment period, 6 month treatment period and a 12 month follow-up period.
Elevated plasma zonulin levels, which are supportive of a diagnosis of CD (celiac disease) in children with gastrointestinal symptoms, may indicate patients with difficult-to-manage NS who will benefit from initiation of a GFD (gluten free diet). This pilot study will determine whether high plasma zonulin levels can be used as a screening tool to identify patients with NS (nephrotic syndrome) who are likely to demonstrate a beneficial response to a GFD. It will provide important information about the feasibility of testing the efficacy of a GFD for this condition and assist in the design and sample size calculation for a definitive trial to test the beneficial effect of this dietary intervention. Although NS is a rare condition in childhood, it is a chronic disease that can lead to short- and long-term disability especially in those with difficult-to-manage disease. There is an urgent need to develop safe and effective new therapies in this subgroup. This project may indicate the utility of a common dietary modification, a GFD, to treat these patients. The growing medical use of and greater access to gluten-free food items underscore the feasibility and timeliness of this approach.
the present study was conducted to assess the population pharmacokinetics of tacrolimus in children with nephrotic syndrome and to use these data to calculate an optimal dosing regimen of tacrolimus for use in these patients.
This is a multisite, open-label, prospective and registered study designed to evaluate the efficacy and safety of Huai-Qi-Huang granule in children with primary nephrotic syndrome.
Nephrotic syndrome (NS) represents one of the most common diagnoses in pediatric and adult nephrology, with a prevalence of 16 per 100,000 children and 3 per 100,000 adults in Western countries. In most cases, the pathogenesis of NS remains elusive, and the clinical phenotype of patients does not allow discrimination among different causes. Thus, children with NS are usually treated with corticosteroids before a biopsy is taken, and approximately 80% of them respond to such a treatment. According to this observation, pediatric NS has been separated into two broad categories; Steroid-Sensitive Nephrotic Syndrome (SSNS) and Steroid-Resistant Nephrotic Syndrome (SRNS). In both these categories the biopsy result is usually Minimal Change Disease (MCD) while a few may show Focal and Segmental Glomerulosclerosis (FSGS). Although children affected by SSNS have good long-term prognosis, most patients with SRNS progress to End Stage Renal Disease (ESRD) within 2-10 years of diagnosis . In adults a biopsy diagnosis of FSGS is more common than in children and more patients will not respond to corticosteroids alone and will need additional immunosuppressant medication. About 40% will progress to ESRD within 10 years . Currently, at least 19 genes have been clearly identified with association to SRNS harboring ~300 independent mutations, conferring a considerable genetic heterogeneity to the disorder. Genetic testing is emerging as a useful diagnostic tool in SRNS as it has implications for clinical course, treatment response, risk for posttransplant proteinuria and prenatal diagnosis. An approach for genetic testing based on the current evidence seems cost-effective and may help in the best possible management of SRNS . The NPHS2 gene, is located on chromosome 1 and is also known as the Podocin gene. It encodes the podocin protein. Podocin is a 383-amino acid lipid-raft-associated protein localized at the slit diaphragm, where it is required for the structural organization and regulation of the glomerular filtration barrier. Its interaction with other slit diaphragm proteins eg. nephrin, NEPH1, CD2AP and TRPC6 is important in mechanosensation signaling, podocyte survival, cell polarity, and cytoskeletal organization . It has been reported that variants in the NPHS2 gene are associated with NS . The commonly studied rs61747728 NPHS2 gene polymorphism also known as p.R229Q has been reported to be associated with NS and SRNS . However others have failed to report an association , which might be due to population differences. The rs61747728 is a non-synonymous variant found on exon 5 which is suggested to be involved in in altering the functional properties of podocin in vitro and possibly in vivo . The investigators will therefore investigate the frequency of the p.R229Q variant in Middle East patients with NS. Genetic analysis will have important implications in several aspects:- 1. Understanding the biology of the disease in this part of the world. 2. Counselling patients about their clinical course and what medication they will respond to. 3. Counselling patients about the possibility of a kidney transplant sooner in their disease course
This will be an open-label, randomized controlled trial which compares continued treatment with high dose prednisone (standard therapy) to treatment with rituximab in patients with minimal change disease or focal segmental glomerulosclerosis unresponsive to 8 weeks of high dose prednisone . patients either receive 2 doses of Rituximab 375 mg/m2 iv at time 0 and 14 days with termination of prednisone or standard therapy which consist of 8 additional weeks of high dose prednisone treatment.
Childhood nephrotic syndrome is the most frequent glomerular disease that presents during childhood,primarily owing to a disturbed immune function.This disease is characterized by alterations in selectivity at the glomerular capillary wall that lead to an inability to restrict the urinary loss of protein.
Nephrotic syndrome (NS) is among the most common pediatric kidney diseases and is defined as massive proteinuria (>40 mg/m2/h or urine protein to creatinine ratio >2 g/g) leading to hypoalbuminemia (<2.5 g/dL), edema, and hyperlipidemia. 60-70 % of patients present prior to age of 6 years
Traditionally MCN is treated with a high dose of prednisolone, which induces remission in 60-90% of patients. Prednisolone treatment contains numerous side effects and the current dose is empiric. Given the lack of efficacy evidence and the risk associated with the currently accepted treatment regimen there is a need to characterize the outcome in MCN further, and to establish new, and potentially less toxic treatment regimens. The aim is to examine if treatment with reduced dose of prednisolone in combination with activated vitamin D is as effective as standard high dose prednisolone in achieving remission and preventing relapse in MCN, and if reduced dose prednisolone is associated with fewer side effects compared to standard dose. Furthermore, the study will examine the influence of prednisolone metabolism on the efficacy and side effects of prednisolone in the treatment of MCN.
This study is a multicentric, randomized, parallel group, open label controlled trial of children age 1 year up to 4 years with new onset, idiopathic nephrotic syndrome. It is designed to test the initial duration of steroid therapy of either 3 month or 6 month total duration. Participants will be randomized to either extend their pre-trial 3 months (12 weeks) of standard of care corticosteroid therapy to add an additional 12 weeks of therapy or to stop therapy. Pre-trial standard of care corticosteroids will include 60 mg/m2/day for 6 weeks followed by 40 mg/m2/day every other day for 6 weeks of prednisolone or equivalent. The trial intervention will therefore be an additional 12 vs 0 weeks of corticosteroids in these children with idiopathic nephrotic syndrome.
