Obesity-related glomerulopathy (ORG) is morphologically characterized by glomerulomegaly with or without observable focal segmental glomerulosclerosis under light microscope, with decreased podocyte density and number, and with increased foot‑process width observed under electron microscope. The severity of podocyte injury is correlated with the degree of proteinuria and renal dysfunction. However, the pathogenesis of ORG is not well understood. The aim of the present study was to explore the possible pathogenic role of aldosterone (ALDO) in ORG...

BACKGROUND AND OBJECTIVES: C3 glomerulopathy is a form of complement-mediated GN. Immunosuppressive therapy may be beneficial in the treatment of C3 glomerulopathy. Mycophenolate mofetil is an attractive treatment option given its role in the treatment of other complement-mediated diseases and the results of the Spanish Group for the Study of Glomerular Diseases C3 Study. Here, we study the outcomes of patients with C3 glomerulopathy treated with steroids and mycophenolate mofetil. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a retrospective chart review of patients in the C3 glomerulopathy registry at Columbia University and identified patients treated with mycophenolate mofetil for at least 3 months and follow-up for at least 1 year...

Renal tissue hypoxia is a final pathway in the development and progression of chronic kidney disease (CKD), but whether renal oxygenation predicts renal function decline in humans has not been proven. Therefore, we performed a prospective study and measured renal tissue oxygenation by blood oxygenation level-dependent magnetic resonance imaging (BOLD-MRI) in 112 patients with CKD, 47 with hypertension without CKD, and 24 healthy control individuals. Images were analyzed with the twelve-layer concentric objects method that divided the renal parenchyma in 12 layers of equal thickness and reports the mean R2* value of each layer (a high R2* corresponds to low oxygenation), along with the change in R2* between layers called the R2* slope...

Retinal vasculopathy with cerebral leukodystrophy (RVCL) is a rare autosomal dominant systemic microvascular disease. Neurological disorders and visual disturbance are highlighted as manifestations of RVCL; however, there are few reports focused on nephropathy. Herein, we describe detailed renal histopathological findings in a daughter and father with RVCL, proven by TREX1 genetic analysis. A kidney biopsy of the daughter, 35-year-old with asymptomatic proteinuria, revealed unique and various glomerular changes...

Drugs targeting VEGF (vascular endothelial growth factor) are often associated with rapid development of hypertension by a yet not fully understood mechanism. VEGF is expressed in renal epithelial cells and stimulates NO production. In the renal medulla, inhibition of NO formation by local L-NAME or by impaired endothelin-1 leads to hypertension. The present study was designed to test the hypothesis that VEGF receptor inhibitor treatment leads to hypertension through decreased renal medullary formation of NO and endothelin-1...

A C N Moraes, V F Magalhães
Cylindrospermopsin (CYN) is a cyanotoxin and a hydrophilic alkaloid of 415 Da. The principal effect of CYN is the inhibition of protein synthesis, and it can damage various organs. Studies have demonstrated that the kidney is the most affected organ. CYN has played roles in at least two poisoning cases, i.e., the mysterious Palm Island disease in Australia and the event at Caruaru in Brazil. Therefore, we aimed to determine how CYN disrupts the renal tissue. Dose-response curves following single intraperitoneal injections of purified CYN (at 0, 16, 32, 64 and 128 μg CYN/kg body weight) were created in 10-week-old male BALB/C mice (n = 4)...

Uncontrolled hypertension in children with chronic kidney disease (CKD) has been identified as one of the main factors contributing to progression of CKD and increased risk for cardiovascular disease. Recent efforts to achieve better blood pressure (BP) control have been recommended. The primary objective of this analysis was to compare BP control over 2 time periods among participants enrolled in the CKiD study (Chronic Kidney Disease in Children). Casual BP and 24-hour ambulatory BP monitor data were compared among 851 participants during 2 time periods: January 1, 2005, through July 1, 2008 (period 1, n=345), and July 1, 2010, through December 31, 2013 (period 2, n=506)...

Goodpasture's syndrome is a triad of anti-glomerular basement membrane (anti-GBM) circulating antibodies, glomerulonephritis and pulmonary hemorrhage. We reported a 65-year-old woman with headaches, asthenia and weight loss. Giant cell arteritis was confirmed by temporal artery biopsy. The patient had associated renal condition with moderate acute renal failure, proteinuria and haematuria. Renal biopsy showed extracapillary glomerulonephritis and linear staining of immunoglobulins G along glomerular basement membrane...

BACKGROUND: In ANCA-associated vasculitis the acute phase of the disease is often preceded by prodromal symptoms. The aim of the present study was to analyze the relation between the duration of the prodromal phase and renal damage. METHODS: Patients with ANCA-associated vasculitis and renal involvement from a retrospective single-center cohort were divided into two equal groups based on the duration of the prodromal phase. The prodromal phase was defined as the time between first vasculitis related symptoms and the date of diagnosis...

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...

Fabry disease (FD) is a disorder that results from mutations of hydrolase α-galactosidase A. The enzymatic defect leads to accumulation of globotriaosylceramide (Gb3) in the kidney. Substrate deposition is related to tissue damage in FD, but the relation of urinary Gb3 levels in patients and the renal function markers remain not completely understood. Once nephropathy is one of the main features of FD and is marked by an insidious development, we investigated a possible correlation of Gb3 with biochemical markers of nephropathy including albuminuria, estimated glomerular filtration rate (eGFR), serum creatinine and urea, and proteinuria in male and female patients under or not enzyme replacement therapy (ERT)...

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...

Monoclonal gammopathy with renal significance (MGRS) is a relative new-described entity, diagnosed especially in older patients and deriving from the group with monoclonal gammopathy of undetermined significance (MGUS). Various renal lesions may arise in MGRS, according to the ultrastructural characteristics of the monoclonal immunoglobulin deposition in the kidney, from proliferative glomerulopathies and amyloidosis to light chain proximal tubulopathy and crystal-storing histiocytosis. Although both are considered premalign or non-malignant hematological conditions, kidney involvement in MGRS aggravates the prognosis of the patients and need to be treated aggressively...
