BACKGROUND: Despite the development of biomarkers and noninvasive imaging tools, biopsy remains the only method for correctly diagnosing patients with unexplained hematuria, proteinuria and renal failure. Renal biopsy has been performed for several decades in Taiwan; however, a national data registry is still lacking until 2013. METHODS: The Renal Biopsy Registry Committee was established within the Taiwan Society of Nephrology in January 2013. A biopsy registry format, including basic demographic data, baseline clinical features, laboratory data, and clinical and pathological diagnosis was developed...

Urinary volatile organic compounds (VOCs) profiling has recently received considerable attention because it can be obtained noninvasively and conveniently while it can be successfully used in a variety of diseases and can provide unique biomarkers. The aim of current study was to investigate potential biomarkers between minimal change type nephrotic syndrome (MCNS) and normal. Urinary samples were collected from 38 minimal change type nephrotic syndrome patients and 15 healthy controls. Solid phase microextraction (SPME) and chromatography- mass spectrometry (GC-MS) were used to analysis the urinary metabolites...

The association between nephrotic syndrome (NS), hemophagocytic lymphohistiocytosis (HLH), and certain paraneoplastic syndromes has been documented in the literature. However, nephrotic changes as part of paraneoplastic syndromes are rare in lymphoid malignancies, particularly in non-Hodgkin lymphoma. We report the sudden onset of acute renal failure and NS in a 14-year-old male who initially presented with HLH and was subsequently diagnosed with ALK-positive anaplastic large-cell lymphoma (ALCL). The treatment of ALCL reversed both the HLH and NS findings...

A 42-year-old man with eosinophilia and high serum immunoglobulin E (IgE) developed a lacrimal gland mass on the left side. Excisional biopsy revealed hyperplasia of lymphoid follicles, and infiltration with lymphocytes and eosinophils around lacrimal gland acini, leading to the pathological diagnosis of Kimura disease. IgE-positive cells were mainly found along follicular dendritic cells, and a small number of IgG4-positive cells was present. One month after oral prednisolone was started at 40 mg daily and tapered to 10 mg daily, he developed lower leg edema on both sides and marked proteinuria (10...

Globally sclerotic glomeruli (GSG) occur with both normal aging and kidney disease. However, it is unknown whether any GSG or only GSG exceeding that expected for age is clinically important. To evaluate this, we identified patients with a glomerulopathy that often presents with nephrotic syndrome (focal segmental glomerulosclerosis, membranous nephropathy, or minimal change disease) in the setting of the Nephrotic Syndrome Study Network (NEPTUNE), China-Digital Kidney Pathology (DiKiP), and the Southeast Minnesota cohorts...

A unique characteristic of the response of minimal-change disease (MCD) or focal and segmental glomerulosclerosis (FSGS) to steroid therapy is that the remission of proteinuria occurs quickly, for example, within 4 - 6 weeks of the onset of steroid therapy, even in those with severe nephrotic syndrome. Remission of proteinuria in MCD and FSGS can also occur spontaneously (not steroid induced). However, spontaneous remission usually proceeds over several months or longer. Recently, there have been several reports that abatacept can induce proteinuria remission in MCD and FSGS...

AIMS: Nephrotic syndrome (NS) is a major manifestation of lupus nephritis (LN). The dysregulation of podocyte, glomerular basement membrane (GBM) and endothelial cell (EC) develops proteinuria in glomerular diseases. The aim of our study is to clarify whether the dysregulation of these barriers is associated with NS in proliferative LN and membranous LN. METHODS AND RESULTS: Fifty six patients with NS including minimal change NS in 15, primary membranous nephropathy (PMN) in 13, Class III/IV LN in 15 and Class V LN in 13 were enrolled in this study...

REVIEW
Scott E Wenderfer, Joseph P Gaut
Unique challenges exist in the diagnosis and treatment of glomerular diseases with their onset during childhood. Mounting evidence supports the notion that earlier onset cases occur due to larger numbers of genetic risk alleles. Nearly all causes of adult-onset glomerulonephritis, nephrotic syndrome, and thrombotic microangiopathy have also been described in children, although the prevalence of specific causes differs. Postinfectious glomerulonephritis, Henoch-Schönlein purpura nephritis, and minimal change disease remain the most common causes of glomerular disease in younger children in the United States and can be diagnosed clinically without need for biopsy...

Rituximab (RTX) may benefit patients with glomerular disease who suffer from focal segmental glomerular sclerosis (FSGS) or minimal change disease (MCD). Here, we have described our experience treating 6 FSGS and 9 MCD patients with steroid-dependent/refractory nephrotic syndrome (NS) with RTX. Patients received RTX (375 mg/m2) intravenously on days 1, 8, 23, and 29. During a median follow-up of 8 months (range, 3-36 months) after RTX administration, all patients achieved complete or partial remission. Relapses decreased by approximately 30-fold compared with the year preceding RTX treatment, and an 89...

BACKGROUND: Adult patients with minimal change nephrotic syndrome (MCNS) are often associated with acute kidney injury (AKI). To assess the mechanisms of AKI, we examined whether tubular cell injuries unique to MCNS patients exist. METHODS: We performed a retrospective analysis of clinical data and tubular cell changes using the immunohistochemical expression of vimentin as a marker of tubular injury and dedifferentiation at kidney biopsy in 37 adult MCNS patients...

Minor infections, allergies, insect bites, and bee stings are commonly reported causes of nephrotic syndrome (NS). Herein, we report, to the best of our knowledge, the first case of NS relapse due to Kawasaki disease (KD). An 8-year-old boy presented with high fever of 4-day duration. He had developed steroid-dependent NS at the age of 4 years and remained in remission after steroid and mizonbin therapy. Renal biopsy, performed at the age of four, showed minimal change (MC) disease. Upon examination, the patient fulfilled 5 of 6 criteria for KD under the Japanese diagnostic guidelines, with positive proteinuria...

The efficacy of B cell depletion therapies in diseases such as nephrotic syndrome and rheumatoid arthritis suggests a broader role in B cells in human disease than previously recognized. In some of these diseases, such as the minimal change disease subtype of nephrotic syndrome, pathogenic antibodies and immune complexes are not involved. We hypothesized that B cells, activated in the kidney, might produce cytokines capable of directly inducing cell injury and proteinuria. To directly test our hypothesis, we targeted a model antigen to the kidney glomerulus and showed that transfer of antigen-specific B cells could induce glomerular injury and proteinuria...

Rituximab (RTX), a specific antibody to human CD20, has been successfully used to treat intractable nephrotic syndrome (NS). Recent studies have suggested a direct effect of RTX on podocytes by targeting sphingomyelinase phosphodiesterase acid-like 3b (SMPDL-3b). Thus, we examined the urinary excretion of SMPDL-3b as well as its immunoreactivity in biopsy specimens from children with intractable NS. Urine samples from six patients (five with minimal-change NS and one with focal segmental glomerulosclerosis) and from four healthy adults were examined...

Minimal-change nephrotic syndrome (MCNS) is an immune-mediated glomerular disease. We have analyzed the modifications on T-cell subsets in twenty-three patients who were highly steroid/calcineurin inhibitor and/or mycophenolate mofetil-dependent for frequently relapsing nephrotic syndrome (FRNS) and who were enrolled in a multicenter, double-blind, randomized, placebo vs Rituximab-controlled trial. Patients with FRNS entered the trial at remission and were randomly assigned to receive either Rituximab or placebo...

A 68-year-old man was admitted to our hospital to undergo an examination for nephrotic syndrome while concurrently complicated with recurrent thymoma in the parietal pleura and retroperitoneum. He had been diagnosed with invasive thymoma and had undergone thymo-thymectomy seven years previously. Based on the renal biopsy findings, his nephrotic syndrome was ascribed to minimal change disease. He was treated with corticosteroid monotherapy, which resulted in complete remission six months later, despite the fact that the recurrent thymoma remained...

Nephrotic syndrome is defined by a triad of clinical features: oedema, substantial proteinuria (> 3.5 g/24 hours) and hypoalbuminaemia (< 30 g/L). It is often associated with hyperlipidaemia, thromboembolism and an increased risk of infection. Nephrotic syndrome develops following pathological injury to renal glomeruli. This may be a primary problem, with a disease specific to the kidneys, or secondary to a systemic disorder such as diabetes mellitus. The most common cause in children is minimal change glomerulonephritis...

BACKGROUND: Differential diagnosis between primary focal segmental glomerulosclerosis (FSGS) and minimal change disease (MCD) is sometimes difficult as nephrotic syndrome is the main clinical symptom in both diseases. OBJECTIVES: This study has attempted to evaluate the urinary excretion of Th1 and Th2 cytokines as potential biomarkers in distinguishing the two types of nephrotic syndrome, and predicting outcome of renal function. PATIENTS AND METHODS: Thirty-six patients with FSGS (M/F 22/14, Age; 41...

This descriptive and comparative review examines the changing epidemiology, treatment, renal and patient outcome of childhood nephrotic syndrome (NS) in tropical Africa (TpAfr). In the 1960s to 1980s, corticosteroid-resistant non-minimal change disease (nMCD) including quartan malaria nephropathy (QMN) was the dominant renal histopathology type. The overall incidence of NS was 0.35-1.34% of hospital admissions. Median age at onset of NS ranged between 4.0 and 12.0 years while the mean (SD) age range was 5.8 (3...

Gastric cancer is one of the most common cancers and the second leading cause of cancer‑associated mortality worldwide. Recurrence, metastasis and resistance to drug treatment are the main barrier to survival of patients with advanced stage gastric cancer. Further study of the molecular mechanisms involved will improve the therapeutic options for gastric cancer. In a previous study, c‑Maf was discovered as an oncogene transduced in the avian AS42 retrovirus, and was found to be overexpressed in multiple myeloma and angioimmunoblastic T‑cell lymphoma...
