IgA nephropathy (IgAN) is the most common primary glomerulonephritis in developed countries and a leading cause of chronic kidney disease. IgAN is a mesangial proliferative glomerulonephritis characterized by diffuse mesangial deposition of IgA, often accompanied by the deposition of IgG and the C3 component of complement in a similar distribution. This condition is in most cases oligosymptomatic, often discovered coincidentally. Currently, there is no specific treatment available for IgAN and the use of immunosuppression therapy is debated...

Patients affected by chronic kidney disease (CKD) exhibit a high risk of cardiovascular mortality that is poorly explained by traditional risk factors. There is a growing awareness about the role of derangement of mineral metabolism that is currently accepted as a trigger and sustainer of cardiovascular disease (CVD) in CKD patients. The synthetic definition of CKD mineral and bone disorder (CKD-MBD) split the concept that the indexes of mineral metabolism extend their effects beyond the bone until the vascular wall and metabolic milieu of CKD patients through complex pathways...

A direct and independent association between serum phosphate (P) levels and mortality has been reported. High circulating P concentrations, still within the normal range, was associated with unfavourable outcomes in normal subjects as well as in chronic kidney disease (CKD) patients. Experimental data support the notion that P overload may hamper survival expectancy, directly inducing vascular, skeletal, and renal ageing. The balance of P results from dietary intake, intestinal absorption, glomerular filtration, tubular resorption, and hormonal asset...

Medial arterial calcification (MAC) and renal osteodystrophy are complications of mineral bone disease (MBD) associated with chronic kidney disease (CKD). Our aim was to develop a novel mouse model to investigate the clinical course of CKD-MBD. Eight-week-old C57BL/6 J male mice were assigned to the following groups: the control group, fed a standard chow for 6 or 12 weeks; the CKD-normal phosphorus (NP) group, fed a chow containing 0.2% adenine, with normal (0.8%) phosphorus, for 6 or 12 weeks; and the CKD-high phosphorus (HP) group, fed 6 weeks with the 0...

INTRODUCTION: Metabolism and plasma concentration of lipids and lipid-derived compounds play an important role in kidney physiology and pathological processes. The component of membrane phospholipids - arachidonic acid (AA) and its active derivatives - eicosanoids are involved in the development of hypertension, diabetes, inflammation and may contribute to progression of chronic kidney disease (CKD). The purpose of the study was to determine, whether the type of renal replacement therapy has an effect on eicosanoids metabolism...

Magnetic resonance imaging (MRI) examinations provide high-resolution information about the anatomic structure of the kidneys and are used to measure total kidney volume (TKV) in patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD). Height-adjusted TKV (HtTKV) has become the gold-standard imaging biomarker for ADPKD progression at early stages of the disease when estimated glomerular filtration rate (eGFR) is still normal. However, HtTKV does not take advantage of the wealth of information provided by MRI...

Little is known regarding the ways in which chronic kidney disease (CKD) prevalence and progression differ between the sexes. Still less is known regarding how social disparities between men and women may affect access to care for CKD. In this review, we briefly describe biological sex differences, noting how these differences currently do not influence CKD management recommendations. We then describe what is known within the published literature regarding differences in CKD epidemiology between sexes; namely prevalence, progression, and access to treatment throughout the major world regions...

BACKGROUND: National levels of personal health-care access and quality can be approximated by measuring mortality rates from causes that should not be fatal in the presence of effective medical care (ie, amenable mortality). Previous analyses of mortality amenable to health care only focused on high-income countries and faced several methodological challenges. In the present analysis, we use the highly standardised cause of death and risk factor estimates generated through the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) to improve and expand the quantification of personal health-care access and quality for 195 countries and territories from 1990 to 2015...

BACKGROUND: Renal involvement in Fabry disease is a major determinant of overall disease prognosis and early enzyme replacement therapy seems effective in preventing progression of kidney injury. Gb3 storage, glomerular sclerosis and tubulo-interstitial fibrosis may occur with minimal or no changes on standard renal tests, hence alternative markers of renal dysfunction are crucial. In this study we compared several biomarkers with albuminuria in the identification of incipient Fabry nephropathy and their diagnostic accuracy to identify chronic kidney disease (CKD) stage≥2...

Diabetic kidney disease develops in approximately 40% of patients who are diabetic and is the leading cause of CKD worldwide. Although ESRD may be the most recognizable consequence of diabetic kidney disease, the majority of patients actually die from cardiovascular diseases and infections before needing kidney replacement therapy. The natural history of diabetic kidney disease includes glomerular hyperfiltration, progressive albuminuria, declining GFR, and ultimately, ESRD. Metabolic changes associated with diabetes lead to glomerular hypertrophy, glomerulosclerosis, and tubulointerstitial inflammation and fibrosis...

During pregnancy, CKD increases both maternal and fetal risk. Adverse maternal outcomes include progression of underlying renal dysfunction, worsening of urine protein, and hypertension, whereas adverse fetal outcomes include fetal loss, intrauterine growth restriction, and preterm delivery. As such, pregnancy in young women with CKD is anxiety provoking for both the patient and the clinician providing care, and because the heterogeneous group of glomerular diseases often affects young women, this is an area of heightened concern...

BACKGROUND: The ability of antihyperuricemic therapy to exert renoprotective effects in patients with chronic kidney disease (CKD) is controversial. In the present study, we studied patient characteristics that may mask favorable impact of antihyperuricemic therapy on the progression of CKD. METHODS: This was a single-center, retrospective, follow-up study. One-hundred and seventy-eight CKD patients with hyperuricemia who received febuxostat therapy were included in this study...

Hyperuricaemia is a metabolic disease caused by purine metabolic abnormalities, mainly due to the increased formation or reduced excretion of uric acid. In recent years, it has been proved that hyperuricaemia is an important risk factor for chronic kidney disease (CKD) and cardiovascular disease, and it also takes part in the pathophysiology of metabolic syndrome. In addition, more attention has been concentrated on the pathogenesis or treatment of hyperuricaemia. Since establishing an animal model on hyperuricaemia is the foundation for further researches, several methods to establish the hyperuricaemia model have been developed...

BACKGROUND: Hypertension is a leading cause of kidney disease worldwide, and chronic kidney disease (CKD) is a known cause of secondary hypertension. Blood pressure (BP) control is a main-stay in the management of CKD because it retards the progression of established CKD. AIM: To determine BP control and its associated factors in predialysis CKD patients in a tertiary hospital setting.

Renal fibrosis is the most common outcome of chronic kidney disease (CKD), while the pathogenesis of renal fibrosis is not fully understood. In this study, we first showed that the progress of renal fibrosis was positively related to serum levels of indoxyl sulfate, a typical protein-bound toxin, and that there was a close correlation between serum indoxyl sulfate levels and β-catenin expression in the kidneys (r = 0.908, p < 0.001) of CKD patients. We then demonstrated that intraperitoneal injections of indoxyl sulfate (100 mg/kg/day) for 4 weeks in uninephrectomized mice explicitly induced renal fibrosis, which was accompanied by a significant activation of Wnt/β-catenin signaling...

Epidemiological and experimental studies reveal that Western dietary patterns contribute to chronic kidney disease, whereas dietary restriction (DR) or dietary polyphenols such as green tea polyphenols (GTPs) can ameliorate the progression of kidney injury. This study aimed to investigate the renal protective effects of GTPs and explore the underlying mechanisms. Sixty Wistar rats were randomly divided into 6 groups: standard diet (STD), DR, high-fat diet (HFD), and three diets plus 200 mg/kg(bw)/day GTPs, respectively...

The prevalence of chronic kidney disease (CKD) is high and it is gradually increasing. Individuals with CKD should introduce appropriate measures to hamper the progression of kidney function deterioration as well as prevent the development or progression of CKD-related diseases. A kidney-friendly diet may help to protect kidneys from further damage. Patients with kidney damage should limit the intake of certain foods to reduce the accumulation of unexcreted metabolic products and also to protect against hypertension, proteinuria and other heart and bone health problems...

BACKGROUND: Risk factors for estimated glomerular filtration rate (eGFR) decline beyond albuminuria are not fully understood in Indigenous Australians who have a 6-fold risk of end-stage kidney disease. We assessed associations between cardio-metabolic risk factors and eGFR decline according to baseline albuminuria status to identify potential treatment targets. METHODS: The eGFR Follow-up study is a longitudinal cohort of 520 Indigenous Australians. Linear mixed regression was used to estimate associations between baseline cardio-metabolic risk factors and annual Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) eGFR change (ml/min/1...

BACKGROUND: Nuclear factor erythroid 2-related factor 2 (NRF2) is a critical transcription factor for the antioxidative stress response and it activates a variety of cytoprotective genes related to redox and detoxification. NRF2 activity is regulated by the oxidative-stress sensor molecule Kelch-like ECH-associated protein 1 (KEAP1) that induces proteasomal degradation of NRF2 through ubiquitinating NRF2 under unstressed conditions. Because oxidative stress is a major pathogenic and aggravating factor for kidney diseases, the KEAP1-NRF2 system has been proposed to be a therapeutic target for renal protection...
