Hepatitis C virus (HCV) infection affects many organs in the body, including the liver, kidneys, skin, joints and others. Although the hepatic manifestation of HCV has been widely studied, the extrahepatic manifestaions of HCV have not been fully appreciated. Studies have shown that patients with HCV have a higher risk of chronic kidney disease and end-stage renal disease, as well as poorer outcomes after kidney transplantation. Given these findings, it is important to screen HCV patients for presence of renal impairement in a timely manner...

C3 glomerulonephritis (C3GN) and dense deposit disease comprise the two classes of C3 glomerulopathy. Studies from Europe and Asia have aided our understanding of this recently defined disorder, but whether these data apply to a diverse United States patient population remains unclear. We, therefore, reviewed clinical and histopathological data, including generation of a C3 Glomerulopathy Histologic Index to score biopsy activity and chronicity, to determine predictors of progression to end-stage renal disease (ESRD) and advanced chronic kidney disease (CKD) in 111 patients (approximately 35% non-white) with C3 glomerulopathy: 87 with C3GN and 24 with dense deposit disease...

The human immunodeficiency virus (HIV) infection can lead to progressive decline in renal function known as HIV-associated nephropathy (HIVAN). Importantly, individuals of African ancestry are more at risk of developing HIVAN than their European descent counterparts. An in-depth search on Google Scholar, Medline and PubMed was conducted using the terms "HIVAN" and "pathology and clinical presentation", in addition to "prevalence and risk factors for HIVAN", with special emphasis on African countries for any articles published between 1990 and 2017...

Glomerulonephritis is one of the most serious manifestations of systemic lupus erythematous (SLE). Because SLE is ≥10 times more common in women, a role for estrogens in disease pathogenesis has long been suspected. Estrogen receptor α (ERα) is highly expressed in renal tissue. We asked whether ERα expression contributes to the development of immune-mediated nephropathies like in lupus nephritis. We tested the overall effects of estrogen receptors on the immune response by immunization with OVA and induction of chronic graft-versus-host disease in female ERα-knockout mice...

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...

BACKGROUND: Pediatric hematuria/proteinuria is a risk factor for chronic kidney disease in later life, and school urinary screening can detect asymptomatic glomerulonephritis in the early stage. This study aimed to evaluate the prevalence of hematuria/proteinuria and its association with different socio-demographic factors among school children in 2013 in Hualien, Taiwan. METHODS: A cross-sectional study was conducted among first, fourth, and seventh graders. Health examination results and urinalysis data were analyzed...

IgA-dominant infection-related glomerulonephritis (IRGN) is a distinct morphologic variant of IRGN, characterized by dominant or codominant glomerular deposits of IgA, mostly in elderly and patients with diabetes. More cases are being reported in recent times due to increased awareness of the disease entity and increased rate of Staphylococcus infection. It usually presents as rapidly progressive renal failure with proteinuria, and treatment guidelines for this disease entity are not well defined. We report here 12 cases of IgA-dominant IRGN seen over a period of 5 years from a single center...

BACKGROUND: Chronic glomerulonephritis (CGN) is the most common form of primary glomerular disease with unclear molecular mechanisms, which related to immune-mediated inflammatory diseases. Our study intended to identify potential long non-coding RNAs (lncRNAs) and genes, and to determine the potential molecular mechanisms of CGN pathogenesis. METHODS: The microarray of GSE64265 and GSE46295 were downloaded from the Gene Expression Omnibus database, GSE64265 including 3 rats control kidney tissues and 5 rats model kidney tissues, GSE46295 including 3 rats control kidney tissues and 3 rats model kidney tissues, which was on the basis of GPL1355 platform...

The global burden of chronic kidney disease (CKD) has increased substantially in recent years, partly attributed to the global epidemic of diabetes mellitus. In many countries including China, glomerulonephritis was the most common cause of end stage renal disease (ESRD). The mortality rate of dialysis patients can be as high as patients with colon, breast and prostate cancers. CKD has important socio-economic impact on the healthcare system and society. Increasing awareness and early detection of CKD cannot be overemphasized...

Hematopoietic cell transplantation (HCT) is an increasingly used treatment for hematologic malignancies as well as for non-malignant diseases. Kidney impairment remains an important early and late posttransplant complication. Numerous histopathologic changes have been reported but the pathophysiology is still incompletely understood. Furthermore, correlations between clinical findings and morphologic changes are not well studied. Between 2000 and 2016, 17 patients after allogeneic (n=12) or autologous (n=5) HCT underwent kidney biopsy for either proteinuria or deterioration of kidney function at our center...

Introduction: HIV-associated nephropathy (HIVAN) has been strongly linked to African ancestry. However, studies have demonstrated wide variability in the prevalence of HIVAN in different sub-Saharan African populations. Accurate assessment of the disease burden is important because antiretroviral therapy (ART) is increasingly available and may prevent progression to end-stage renal disease. Methods: We prospectively screened ART-naïve, afebrile, nonhypertensive, and nondiabetic adults attending a large HIV care program in Western Kenya for the presence of albuminuria (dipstick albumin ≥ trace or urine albumin to creatinine ratio [UACR] ≥ 30 mg/g)...

OBJECTIVES: Recurrent glomerulonephritis can negatively affect kidney allograft survival. However, how primary renal disease affects transplant outcomes in the new era of immunosuppression remains unclear. MATERIALS AND METHODS: We categorized 426 kidney transplant recipients (performed from 1996 to 2007) into 4 disease groups: (1) 99 recipients with biopsy-proven immunologically mediated kidney disease, (2) 40 recipients with urologic disease, (3) 67 recipients with polycystic kidney disease, and (4) 220 recipients with other causes of terminal renal failure/uncertain kidney disease...

Carnosinase (CN1) is a dipeptidase, encoded by the CNDP1 gene, that degrades histidine-containing dipeptides, such as carnosine, anserine and homocarnosine. Loss of CN1 function (also called carnosinase deficiency or aminoacyl-histidine dipeptidase deficiency) has been reported in a small number of patients with highly elevated blood carnosine concentrations, denoted carnosinaemia; it is unclear whether the variety of clinical symptoms in these individuals is causally related to carnosinase deficiency. Reduced CN1 function should increase serum carnosine concentrations but the genetic basis of carnosinaemia has not been formally confirmed to be due to CNDP1 mutations...

Reagent strip urinalysis is a very simple and affordable way to detect proteinuria. This mean, however efficient, generally requires further laboratory analysis of an early morning urine sample, as readily available. Lately, urinary albumin-to-creatinine ratio (ACR) has largely taken over other detection methods by its precision and ability to foreshow earlier stages of diabetic nephropathy. The confirmation of this biological abnormality enables chronic kidney disease staging, helps appreciate the risk it is associated with, and must lead to different interventions in order to reduce its burden : cause determination (which might eventually lead to a kidney biopsy) ; renin-angiotensin-system blockade in every ACR ⟩ 300 mg/g patients (or in ACR 30 - 300 mg/g diabetic patients) ; hypertension control ; or specific treatment (e...
