Efficacy of Rituximab For the Treatment of Calcineurin Inhibitors Dependent Nephrotic Syndrome During...

Childhood Idiopathic Nephrotic Syndrome

Background Idiopathic nephrotic syndrome is a rare disease beginning during childhood and treated with immunosuppressants (i.e. steroids, mycophenolate mofetil, cyclophosphamide, cyclosporine). Renal function of patients suffering from severe, steroid-dependent nephrotic syndrome with failure or toxic side effects of other immunosuppressant treatments is a major matter of concern. Cyclosporine endangers renal parenchyma (fibrosis) in these patients who must take this treatment for years. At the same time, low doses of cyclosporine allow proteinuria to reappear, which provokes degradation of renal function by focal segmental glomerulosclerosis. Some recent data lead to the conclusion that Rituximab may be effective in such a disease, with a cyclosporin sparing effect. Purpose The aim of the study is to evaluate the efficacy of Rituximab versus placebo in the treatment of pediatric patients suffering from severe cyclosporine-dependent nephrotic syndrome. Abstract Patients will be included in the study in a period of remission of proteinuria. Two infusions of Rituximab - at the dose of 375 mg/m²- or placebo will be administered at one week of interval. Other immunosuppressant treatments will be gradually tapered off with the same tapering pattern in both groups. In case of relapse of nephrotic syndrome, the blinding code will be broken. Rituximab will then be infused to patients having received placebo.

Nephrotic SyndromeFocal Segmental Glomerulosclerosis1 more

The purpose of this study is evaluate if abatacept is effective and safe in decreasing the level of protein loss in the urine in patients with excessive loss of protein in the urine (nephrotic syndrome) due to either focal segmental glomerulosclerosis (FSGS) or minimal change disease (MCD). Candidates must have a prior kidney biopsy with either diagnosis. Another kidney biopsy will not be required as part of the study. Candidates must have failed or be intolerant of prior therapy for their kidney disease. The failed or intolerant therapy must include corticosteroids and at least one other drug. Candidates can be adults and children over the age of 6. Abatacept will be administered by venous infusion every 4 weeks.

Nephrotic Syndrome

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.

Rituximab for Idiopathic Nephrotic Syndrome

Idiopathic Nephrotic Syndrome

Open-label, randomized, controlled trial due to value whether the monoclonal antibody rituximab is non-inferior to steroids in maintaining remission in juvenile forms of SDNS. The investigators will enroll 30 pediatric patients affected by idiopathic nephrotic syndrome, who have been in treatment with steroids for at least one year. The lowest dose of drug required to maintain a stable remission will be between 0.4 and 0.7 mg/ kg/ day. This trial provides an initial run-in phase of one month during wich remission will be achieved by means of a standard oral prednisone course. Once remission has been achieved children will be randomized in a parallel arm open label RCT to continue prednisone alone for one month (control) or to add a single intravenous infusion of rituximab (375 mg/m2 - intervention). Prednisone will be tapered in both arms after one month.

Application of Hyperspectral Imaging in the Diagnosis of Glomerular Diseases

GlomerulonephritisIGA6 more

Morning urine samples of patients with IgA nephropathy, idiopathic membranous nephropathy, diabetic nephropathy, and minimal degenerative nephropathy confirmed by renal needle biopsy in our hospital from November 2020 to January 2022 were collected. By scanning the morning urine samples of corresponding patients with microhyperspectral imager, machine learning and deep learning were used to classify microhyperspectral images, and the classification accuracy was greater than 85%. Thus, hyperspectral imaging technology could be used as a non-invasive diagnostic means to assist the diagnosis of glomerular diseases.

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.
