AI Article Synopsis

  • * NF1 shows complete genetic penetrance but has varied clinical presentations, with few reports of glomerular diseases like nephrotic syndrome in patients, particularly children.
  • * This text discusses a specific case of NF1 with nephrotic syndrome, emphasizing the need for thorough evaluations in NF1 patients due to the complexity of their symptoms.

Article Abstract

Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder that caused by NF1 mutations. NF1 gene encodes neurofibromin (a GTPase-activating protein) and plays a regulatory role in many signalling pathway such as the Ras/MAPK pathway, which is important for regulating cell growth, proliferation and neural development. Therefore, NF1 gene mutations causes the excessive activation of signalling pathways and uncontrolled cell growth. NF1 exhibits complete genetic penetrance and clinical heterogeneity. Glomerular disease has rarely been reported in patients with NF1, especially in children. Currently, the relationship between NF1 and nephrotic syndrome is unclear. Here, we present a case of NF1 with nephrotic syndrome and further explore the association between NF1 and glomerular diseases. It also reminds clinicians that NF1 has complex and highly variable clinical manifestations and that a comprehensive workup is essential for patients.

Minimal change disease (MCD) accounts for 10 - 15% of idiopathic nephrotic syndromes in adults. Chronic hepatitis C virus (HCV) infection is rarely ascribed as a cause of MCD and was previously associated with interferon-based therapy. MCD in treatment-naïve chronic HCV infection is extremely rare, with only 3 cases reported in the literature.

Nephrotic syndrome, a multifaceted medical condition characterized by significant proteinuria, has recently prompted a reorientation of research efforts toward B-cell-mediated mechanisms. This shift underscores the pivotal role played by B-cells in its pathogenesis. The aim of this study was to explore potential therapeutic pathways, with specific attention given to compounds found in , including withanolides, such as physalins, which constitute one of the five distinct withanolide subgroups identified in .

Genetic and clinical spectrum of steroid-resistant nephrotic syndrome with nuclear pore gene mutation.

Pediatr Nephrol

January 2025

Department of Nephrology, Wuhan Children's Hospital (Wuhan Maternal and Child Healthcare Center), Tongji Medical College, Huazhong University of Science & Technology, Wuhan, China.

Background: Steroid-resistant nephrotic syndrome (SRNS) is insensitive to steroid therapy and overwhelmingly progresses to kidney failure (KF), the known pathogenic genes of which include key subunits of the nuclear pore complex (NPC), a less-recognized contributor to glomerular podocyte injury.

Methods: After analyzing their clinical characterizations and obtaining parental consent, whole-exome sequencing (WES) was performed on patients with SRNS. Several nucleoporin (NUP) biallelic pathogenic variants were identified and further analyzed by cDNA-PCR sequencing from white cells of peripheral blood, minigene assay, immunohistochemical (IHC) staining, and electron microscopy (EM) ultrastructure observation of kidney biopsy, as well as multiple in silico prediction tools, including 3D protein modeling.

Beyond Redox Regulation: Novel Roles of TXNIP in the Pathogenesis and Therapeutic Targeting of Kidney Disease.

Am J Pathol

January 2025

Division of Nephrology, Department of Internal Medicine, Washington University School of Medicine, St. Louis, MO, USA; Department of Cell Biology & Physiology, Washington University School of Medicine, St. Louis, MO, USA. Electronic address:

Cellular stress conditions, such as oxidative and endoplasmic reticulum (ER) stresses contribute to development of various kidney diseases. Oxidative stress is prompted by reactive oxygen species (ROS) accumulation and delicately mitigated by glutathione and thioredoxin (Trx) antioxidant systems. Initially identified as a Trx-binding partner, thioredoxin interacting protein (TXNIP) is significantly upregulated and activated by oxidative and ER stresses.

Rituximab as a first-line therapy in children with new-onset idiopathic nephrotic syndrome.

Clin Kidney J

January 2025

Department of Nephrology, The Children's Hospital, Zhejiang University School of Medicine, National Clinical Research Center for Child Health, Hangzhou, Zhejiang, China.

Background: Idiopathic nephrotic syndrome (INS) in children, commonly treated with steroids, poses challenges due to associated side effects. Rituximab, known for its efficacy in reducing relapse frequency in difficult-to-treat cases, emerges a potential first-line therapy for pediatric new-onset INS.

Method: This is a single-center, retrospective, observational study to evaluate the efficacy and safety of rituximab as a first-line therapy for pediatric INS.
