Importance: Calcineurin inhibitors are an established first-line corticosteroid-sparing therapy for patients with corticosteroid-dependent nephrotic syndrome (CDNS), whereas B-lymphocyte-depleting therapy is mostly used as a rescue for calcineurin inhibitor-resistant cases. The positive efficacy and safety profile of rituximab raises the question of whether it could be used as a first-line alternative to calcineurin inhibitor therapy. Objective: To compare the efficacy of rituximab and tacrolimus in maintaining relapse-free survival among children with CDNS...

The incidence of idiopathic nephrotic syndrome (NS) is 1·15-16·9 per 100 000 children, varying by ethnicity and region. The cause remains unknown but the pathogenesis of idiopathic NS is thought to involve immune dysregulation, systemic circulating factors, or inherited structural abnormalities of the podocyte. Genetic risk is more commonly described among children with steroid-resistant disease. The mainstay of therapy is prednisone for the vast majority of patients who are steroid responsive; however, the disease can run a frequently relapsing course, necessitating the need for alternative immunosuppressive agents...

Amyloid nephropathy is an uncommon disease that frequently presents with reduced kidney function and proteinuria and, in developed nations, is most often associated with underlying paraproteinemia. The histologic appearance of glomerular amyloid deposition includes mesangial and capillary wall infiltration by an amorphous eosinophilic material, and features of endo- or extracapillary proliferation are not typically seen. Rare cases of crescentic injury have been reported in a subset of patients with amyloid nephropathy, particularly those with amyloid derived from serum amyloid A protein...

Background Steroid-sensitive nephrotic syndrome (SSNS) is a childhood disease with unclear pathophysiology and genetic architecture. We investigated the genomic basis of SSNS in children recruited in Europe and the biopsy-based North American NEPTUNE cohort. Methods We performed three ancestry-matched, genome-wide association studies (GWAS) in 273 children with NS (Children Cohort Nephrosis and Virus [NEPHROVIR] cohort: 132 European, 56 African, and 85 Maghrebian) followed by independent replication in 112 European children, transethnic meta-analysis, and conditional analysis...

Epstein Barr virus (EBV) infections include a wide spectrum of clinical manifestations, ranging from asymptomatic to multiple organ involvement (1). Several complications have been described and renal involvement is usually nephritic and not nephrotic. Nephritic includes haematuria, proteinuria, renal impairment and salt retention causing hypertension and oedema, while nephrotic is defined as heavy proteinuria, with a protein/creatinine ratio of >200 mg/mmol, hypoalbuminemia of <25 g/L and oedema (2-4)...

BACKGROUND: Hypertriglyceridemia thalassemia syndrome is a rare entity with an unknown pathogenetic link. CASE PRESENTATION: We report a case of an 8-month-old female with thalassemia major and increased triglyceride (TG) levels. The clinical features were as in classical thalassemia except for a white discoloration of the plasma. After exclusion of familial triglyceridemia and secondary causes (hypothyroidism, nephrotic syndrome, drugs etc.), a diagnosis of hypertriglyceridemia thalassemia syndrome was made...

PURPOSE: A case report of fatal disseminated cryptococcosis in a patient treated with eculizumab is presented along with a review of literature suggesting a possible etiologic mechanism. SUMMARY: A 23-year-old man with a history of minimal change nephrotic syndrome was hospitalized for acute kidney injury and abdominal pain and swelling. He was found to have disseminated pneumococcal disease, including peritonitis, bacteremia, and pulmonic endocarditis. The patient developed evidence of microangiopathic hemolytic anemia, leading to a diagnosis of atypical hemolytic uremic syndrome, and was started on eculizumab...

Venous thrombosis is recognized as one of the most important complications of nephrotic syndrome (NS). In patients with NS, venous thrombosis may develop in the renal veins, the deep veins of the lower limb, and the inferior vena cava. Here, we describe a case report of an NS patient with multiple venous thrombosis in the right renal vein, the left iliac vein, the vena cava inferior, the right atrium, and the pulmonary arteries. Moreover, we describe the successful treatment of multiple venous thrombosis with prolonged thrombolytic treatment in spite of an increased risk of bleeding due to renal biopsy...

Steroid-resistant nephrotic syndrome represents about 10-20% of pediatrics' nephrotic syndrome. The regeneration of glomerular barrier seems pivotal for cessation of proteinuria. Nephronectin (NPNT) plays a major role in nephrogenesis, signal transduction, and epithelial-mesenchymal interactions. This study aims to preliminary assess NPNT as potential noninvasive biomarker of glomerular regeneration and its ability to identify steroid resistance. In this case control study, 80 retrospectively selected patients with nephrotic syndrome were enrolled in addition to 40 healthy controls...

INTRODUCTION: Chronic lymphoid leukemia (CLL) is a hematological malignant disease, associated with a clonal B cell proliferation. The incidence is 4400 new cases per year in France. The prevalence increases with age with a median age at diagnostic of 65 years. Renal involvement is rare and estimated at 1.2% of patients with CLL. Renal pathological diagnoses associated with CLL are variable and are not always related to the hematological disease. We report here on cases of patients with CLL who underwent a renal biopsy over the past 16 years in Marseille...

Chronic kidney disease (CKD) is associated with significant infectious complications leading to adverse health outcomes. This increased susceptibility to infection can be related to the nephropathy itself as observed in nephrotic syndrome, to the treatment especially in situations requiring immunosuppressive drugs or related to dialysis. Despite a less effective response to vaccination, some data emphasize similar benefits from immunization among people with CKD to the general population. However, some situations encountered in nephrology require adaptation of immunization practices...

A 76-year-old woman suddenly developed anasarca and a fever, and an examination revealed thrombocytopenia, reticulin fibrosis, and acute kidney injury, yielding the diagnosis of TAFRO syndrome. Renal replacement therapy and steroid treatment were soon started. Her proteinuria was minor at first; however, once the kidney function improved, nephrotic syndrome occurred. A kidney biopsy showed membranoproliferative glomerulonephritis-like glomerulopathy with massive macrophage infiltration. Although kidney dysfunction is often observed in TAFRO syndrome patients, its detailed mechanism is unclear...

BACKGROUND: Proteinuria, in addition to haematuria, is the most important laboratory parameter in patients with nephro-urological diseases. Low molecular weight proteinuria (LMWP) is of particular importance because some diseases genetic and tubulointerstitial are diagnosed based on its presence. AIM: The purpose of this study is to describe the clinical features, the course and outcome of pediatric patients with a renal disease associated with LMWP. MATERIAL AND METHODS: This retrospective observational study included 250 pediatric patients with various kidney diseases in which the type of proteinuria was defined by 4-20% gradient gel sodium dodecyl sulphate polyacrylamide gel (SDS-PAG) electrophoresis...

Astragali Radix (AR) has been used in the traditional Chinese medicine (TCM) in the treatment of various renal diseases for many years. In this study, a NMR based metabolomic approach coupled with biochemical assay and histopathological inspection had been employed to study the protective effect of total flavonoids (TFA) in AR against adriamycin-induced nephropathy using rats model. Multivariate analysis revealed that 11 of perturbed metabolites could be reversed by TFA, and the MetaboAnalyst analysis revealed that the anti-nephrotic syndrome effect of TFA was probably related with regulation of alanine, aspartate and glutamate metabolism, citrate cycle, pyruvate metabolism, cysteine and methionine metabolism and glyoxylate and dicarboxylate metabolism...

BACKGROUND: Steroid-resistant nephrotic syndrome (SRNS) has a heterogeneous spectrum of monogenic causes that substantially differ among populations. The aim of this study was to analyse the genetic aetiology of SRNS in Czech and Slovak paediatric patients. METHODS: We analysed clinical data from 74 patients (38 boys) with congenital (15%), infant (14%), and childhood-onset (71%) SRNS collected from the Czech Republic and Slovakia from 2000 to 2017 (inclusive). The DNA samples were first analysed by Sanger sequencing (genes NPHS2, NPHS1, and WT1) and then by next generation sequencing (NGS) using a targeted panel of 48 genes previously associated with SRNS...
