Filter by:Study objective: To investigate the potential therapeutic efficacy of enteric-coated mycophenolate sodium combined with low-dose corticosteroid as first-line treatment for minimal change nephrotic syndrome (MCNS).
To determine the efficacy of tacrolimus in the management of NS(nephrotic syndrome) , the investigators designed this prospective study. The investigators will enroll 100 children with NS(frequent relapse steroid dependent NS, steroid resistance NS) who will be treated with tacrolimus (0.1-0.2 mg/kg/day in two divided doses over 12 h adjusted to a trough level between 5 and 10 ng/ml) for 12 months in combination with low-dose steroids. Other therapies will be included angiotensin-converting enzyme inhibitors, antihypertensive drugs, multivitamins and lipid-lowering agents. Follow-up is every second week for the first 4 weeks, then monthly. After initiation of tacrolimus therapy, blood was drawn each visit to determine tacrolimus trough levels.
This study will examine the safety and effectiveness of ACTHAR Gel, when used to treat 15 patients diagnosed with "treatment resistant nephrotic syndrome." Nephrotic syndrome is a group of symptoms that includes low levels of protein in the blood, swelling of tissue (edema), especially around the eyes, feet and hands; and high plasma levels of cholesterol. It is caused by a variety of diseases and underlying disorders that damage the kidneys, resulting in excessive excretion of protein in the urine. These diseases damage the glomeruli, which are small blood vessels that filter wastes and excess water from the blood and pass them into the bladder as urine. As a result of protein loss in the urine, the blood is deficient in protein. Normal amounts of blood protein are needed to help regulate fluid throughout the body. Protein in the blood normally draws water from the tissues and into the bloodstream. When blood protein levels are low, the normal movement of water is reversed, and fluid is drawn from the blood and accumulates in the tissues. This excess tissue fluid causes the swelling and puffiness (edema) that is a symptom of nephrotic syndrome. Nephrotic syndrome is described as "treatment resistant" when a patient fails to achieve a sustained partial or complete remission after treatment with at least two first line therapies. The goal of this study is to determine whether injections of ACTHAR Gel (an FDA approved treatment for nephrotic syndrome) over a six month period will lead to a correction of treatment resistant nephrotic syndrome in these patients.
Focal Segmental Glomerulosclerosis (FSGS) is a devastating kidney disease which is difficult to treat and carries a poor prognosis, with 50% of affected children progressing to end stage renal disease (ESRD). The purpose of this study is to investigate oral galactose as a benign treatment for FSGS in children. The investigators hypothesize that galactose, a simple milk sugar thought to bind to the protein factor (FSPF) that causes FSGS thereby inactivating it and stopping it from damaging the kidney, resulting in a reduction in glomerular permeability to albumin and decrease in proteinuria in children with nephrotic syndrome secondary to FSGS.
Idiopathic nephrotic syndrome is steroid-sensitive in more than 90% of cases in children. However 60% of cases are steroid dependent and required treatment with immunosuppressive agent. Cyclophosphamide and ciclosporin are used for long time to reduce steroid dependency, but duration of these treatments should be restricted because of gonadotoxicity for cyclophosphamide and nephrotoxicity for ciclosporin. Mycophenolate mofetil appears as an alternative treatment without gonadotoxicity and nephrotoxicity. However, contrary to cyclophosphamide, mycophenolate mofetil does not seem to have a residual action so that treatment must be maintained during months or years. The aim of the study is to compare efficacy of cyclophosphamide and mycophenolate mofetil in steroid dependent nephrotic syndrome in children.
This is a prospective open labeled trial examining the efficacy of ACTHar Gel (porcine ACTH) on the level of proteinuria in patients with diabetic nephropathy and nephrotic range proteinuria.
To determine if H.P. Acthar Gel (repository corticotrophin) has the same anti-proteinuric effects seen with the synthetic ACTH analogue in Europe.
Membranous nephropathy (MN) may also be secondary to many other diseases (e.g., infections, drugs, neoplasms and autoimmune diseases). In this study, the presence of Helicobacter Pylori (H. pylori) antigen was investigated in renal tissue from needle biopsy samples, and the prevalence of H. pylori infection and the effects of H. pylori eradication on proteinuria level in patients with MN will be investigated.
Background. Patients, especially children, with steroid-dependent or multirelapsing nephrotic syndrome (NS) secondary to minimal change disease (MCD) or idiopathic focal and segmental glomerulosclerosis (FSGS) on continuous treatment with steroids and/or other immunosuppressive agents to limit or prevent recurrences are at increased risk of severe drug-related adverse events. Case reports 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. Objectives. The study is primarily aimed at evaluating whether Rituximab may maintain stable NS remission after tapering and withdrawal of steroid and immunosuppressive therapy in patients with MCD or FSGS and steroid-dependent or multirelapsing NS. Secondarily, the study will assess whether Rituximab allows reducing maintenance doses of steroids and other immunosuppressants (in those who relapse), thus limiting treatment related side effects and costs. Methods. This prospective, sequential, open, study will include 20 patients with histology evidence of MCD or FSGS and steroid-dependant or multirelapsing NS, who are on stable complete or partial remission since at least 1 month and, based on their previous history, are expected to invariably relapse after steroid/immunosuppression withdrawal. After baseline evaluation of clinical, laboratory and kidney function parameters [including glomerular filtration rate (GFR), renal plasma flow (RPF), albumin and sodium fractional clearance and the glomerular albumin permeability assay (Palb)], patients will receive one Rituximab infusion that will be repeated 1 week later if CD20 cells are not fully depleted from the circulation. Then ongoing immunosuppression will be progressively tapered up to complete withdrawal over 6 to 9 months. 24h proteinuria will be monitored monthly and spot urine will be tested daily by albustix to early detect disease relapses. Baseline evaluations will be repeated at study end (1 year). Relapses will be treated with high-dose steroids as per center practice and the last immunosuppressive therapy effective in preventing disease reactivation will be reintroduced. Expected results. Rituximab is expected to prevent NS recurrence following tapering and discontinuation of steroid and other immunosuppressants. Maintaining remission without chronic immunosuppression is expected to minimize risks and costs of therapy and to remarkably improve patient outcomes.
The purpose of this study is to describe the hormones controlling fluid balance in pediatric patients with nephrotic syndrome. Further more, an analysis of the urinary and plasma proteins will be done using proteomics. Different composition of proteins in the urine or plasma might indicate if the patients will respond to treatment or not.
