The rare nature, heterogeneity, and slow evolution of the disorder are major obstacles to systematic genotype-phenotype, intervention, and outcome studies, hampering the development of evidence-based Mar 30, 2021 · Abstract Background: Steroid resistant (SR) nephrotic syndrome (NS) affects up to 30% of children and is responsible for fast progression to end stage renal disease. The disease gets its name because the damage cannot be seen under a regular microscope. It is separated to steroid-sensitive or steroid-resistant (SRNS) forms in respect to the response to intensive steroid therapy. However, managing focal segmental glomerulosclerosis and minimal change disease remains challenging due to unclear pathophysiology Apr 10, 2025 · Furthermore, the 2020 IPNA guidelines recommend the use of calcineurin inhibitors as first-line induction therapy for steroid-resistant nephrotic syndrome (SRNS) [4]. However, some reports of posttransplant recurrence of NS in patients carrying variants in the NPHS2 gene have been described, notably with the p. From a therapeutic point of view, it is important to distinguish between primitive and secondary kidney damage. Minimal Change Disease is the most common cause of nephrotic syndrome in children. ∗To rule out orthostatic proteinuria, the first morning urine should be collected separately for assessment.

Ac … Patients with homozygous or compound heterozygous mutations commonly present with steroid-resistant nephrotic syndrome before the age of 6 years and rapidly progress to end-stage kidney disease with a very low prevalence of recurrence after renal transplantation. SRNS usually progresses to end-stage renal failure. Approximately one-third of these cases are monogenic (caused by pathogenic variants in a single gene), and disease progression is rapid [1,2]. Corticosteroids are the cornerstone of its treatment, and steroid response is the main prognostic factor.

We investigated the value of genetic, histopathologic, and early treatment response information in prognosing long-term renal outcome in children with primary steroid-resistant nephrotic syndrome. 2. Abstract Introduction: Mutations in podocin (NPHS2) gene have the key role in the pathogenesis of steroid-resistant nephrotic syndrome (SRNS) in children, but data is scarce regarding their prevalence and natural course among different all ethnic groups. It is generally an accepted medical practice in pediatric nephrology to perform a kidney biopsy in these patients to clarify the diagnosis and it reveals either FSGS or treatment resistant MCD. Methods After analyzing their clinical characterizations and obtaining parental consent, whole-exome Children who suffer from steroid-resistant nephrotic syndrome (SRNS) require aggressive treatment to achieve remission. More clinical and genetic data from these patients are needed to characterize their genotype-phenotype relationships and elucidate the role of nucleoporins in SRNS. Background: Although steroid therapy is a standard of care for nephrotic syndrome treatment, 15–20% of patients do not respond to it. Uncontrolled studies in patients with FRNS and SDSN have shown that many patients can achieve sustained remission of proteinuria with MMF monotherapy. The former are at risk of steroid toxicity, whereas the latter show a complicated course and may progress to end-stage renal disease (3, 4). INTRODUCTION The nephrotic syndrome (NS) is observed in children with kidney diseases associated with increased permeability of the glomerular filtration barrier. This variation is due to the differences in pharmacokinetics and pharmacodynamics of GCs in each Autoantibodies against the podocyte protein nephrin were recently identified in a pediatric cohort primarily comprising steroid-sensitive (SSNS) and steroid-dependent (SDNS) nephrotic syndrome (NS). Steroids still represent the cornerstone of therapy achieving remission in 75–90% of the cases The remaining part result as steroid resistant nephrotic syndrome, characterized by the elevated risk of developing end stage kidney disease and frequently Steroid-resistant nephrotic syndrome (SRNS) is a common cause of chronic kidney disease in children, and a considerable number of patients progress to end-stage renal disease.

Steroid-resistant nephrotic syndrome (SRNS) is a leading cause of end-stage kidney disease in children. [1,2]. Instead of being exposed to ultimately useless steroid treatment and enduring the side-effects, steroid-resistant patients could have a simple blood or urine test and proceed to treatment Multidrug resistant nephrotic syndrome often leads to kidney failure and can cause relapse after kidney transplant. Steroids still represent the cornerstone of therapy achieving remission in 75–90% of the cases The remaining part result as steroid resistant nephrotic syndrome Idiopathic steroid-resistant nephrotic syndrome (SRNS) is most frequently characterized by focal segmental glomerulosclerosis (FSGS) but also other histological lesions, such as diffuse mesangial sclerosis. e. Most of the patients carrying such variants progress to end stage kidney disease (ESKD) in their childhood. This analysis is performed by Next Generation Sequencing (NGS) and is designed to examine coding regions and splicing junctions.
