Glomerulonephritis (GNs) are one of the most frequent causes of chronic kidney disease (CKD), a renal condition that often leads to end-stage renal failure, and a careful assessment of these diseases is essential for prognostic and therapeutic purposes. The application of MALDI-MSI directly on bioptic renal tissue represents a new stimulating perspective and facilitates the detection of specific proteomic indicators that are directly correlated with the pathological alterations that occur within the glomeruli during the development of glomerulonephritis...

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...

Epidemiologic data suggest that individuals at all stages of chronic kidney disease (CKD) have a higher risk of developing neuropsychiatric disorders, cognitive impairment, and dementia. This risk is generally explained by the high prevalence of both symptomatic and subclinical ischemic cerebrovascular lesions. However, other potential mechanisms, including cytokine/chemokine release, production of reactive oxygen species (ROS), circulating and local formation of trophic factors and of renin-angiotensin system (RAS) molecules, could also be involved, especially in the absence of obvious cerebrovascular disease...

BACKGROUND: Heart failure is common in patients with chronic kidney disease. We studied risk factors for incident heart failure among 3557 participants in the CRIC (Chronic Renal Insufficiency Cohort) Study. METHODS AND RESULTS: Kidney function was assessed by estimated glomerular filtration rate (eGFR) using serum creatinine, cystatin C, or both, and 24-hour urine albumin excretion. During an average of 6.3 years of follow-up, 452 participants developed incident heart failure...

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. METHODOLOGY: CKD patients who attended the renal outpatient clinic during the period from December 2013 to June 2014 were recruited into the study...

Hypertensive disorders of pregnancy (HDP) and chronic kidney disease (CKD) are well-known risk factors for cardiovascular disease (CVD) in later life. However, few studies have investigated the association of HDP with CKD. Moreover, these studies utilized either registry- or clinical-based data and did not include subclinical CKD patients. To address this gap in the literature, we investigated whether HDP is related to CKD, diagnosed based on the estimated glomerular filtration rate (eGFR), in later life. We designed a population-based, retrospective study, and reviewed the results of blood and physiological examinations as well as the results of pregnancy data available in patients' Maternity Health Record Books for 312 women...

BACKGROUND: patients on hemodialysis (HD) report lower physical activity (PA) levels. We analysed factors associated with low levels of PA in patients with chronic kidney disease (CKD) and compared PA on HD day and non-HD. METHODS: 79 patients wore an accelerometer and were classified according to time spent on moderate-vigorous PA (MVPA). Demographic data, BMI, comorbidities, clinical status and health related quality of life (HRQoL) were checked for association with PA...

The coexistence of chronic kidney disease and chronic obstructive pulmonary disease, two age-related conditions, has important clinical and prognostic implications. Respiratory failure is associated with important changes in glomerular and tubulointerstitial function. In contrast, renal failure can affect lung function, mainly by adding a restrictive component or causing complications, such as uremic pulmonary edema and pleural effusion. The effect of age on renal and pulmonary function adds to the complexity of the interplay between the kidney and the lung in these patients...

INTRODUCTION: Etelcalcetide is a novel calcimimetic that binds and activates calcium-sensing receptors (CaSRs) for the treatment of secondary hyperparathyroidism (SHPT). METHODS: To assess titrated dosing regimens, population pharmacokinetic (PK) and PK/pharmacodynamic (PKPD) modeling of etelcalcetide was performed using NONMEM 7.2. In this analysis, plasma etelcalcetide, serum parathyroid hormone (PTH) and calcium (Ca) concentration-time data were collected from five phase I, II, and III clinical trials following single or multiple intravenous doses of etelcalcetide ranging from 2...

Loss of lean body mass is a relevant component of the cachexia, or protein energy wasting (PEW), syndrome. Reduced muscle mass seems to be the most solid criterion for the presence of cachexia/PEW in patients with chronic kidney disease (CKD), and those with greater muscle mass loss have a higher risk of death. Children with CKD have many risk factors for lean mass and muscle wasting, including poor appetite, inflammation, growth hormone resistance, and metabolic acidosis. Mortality risks in patients with CKD increases as body mass index (BMI) and weight decreases...

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...

BACKGROUND: Treatment with statin may be beneficial for patients with chronic kidney disease (CKD). However, the debate over the clinical importance of statin in patients with predialysis advanced CKD remains unresolved. OBJECTIVES: The objective of the article was to evaluate the effect of statin on mortality, cerebrovascular, and renal outcomes in patients with predialysis advanced CKD and dyslipidemia. METHODS: Data on predialysis advanced CKD patients were retrieved from the National Health Insurance Research Database based on the guidelines for prescribing regular erythropoietin-stimulating agent in CKD patients...

Renal osteodystrophy is a feature of chronic kidney disease (CKD), with increasing prevalence as CKD progresses. This bone disease is responsible for major morbidity, including fractures, and a deterioration in the quality of life and its sequelae. Circulating biomarkers of renal osteodystrophy typically indicate bone turnover, but not other features of bone, like bone volume, mineralization, quality or strength. Bone turnover can be considered to be primarily a reflection of bone cell activity, in particular that of osteoblasts and osteoclasts...

Appropriate diagnosis is fundamental in medicine because it sets the basis for the prediction of disease outcome at the single patient level (prognosis) and decisions regarding the most appropriate therapy. However, given the large series of social, clinical and biological factors that determine the likelihood of an individual's future outcome, prognosis only partly depends on diagnosis and aetiology and treatment is not decided solely on the basis of the underlying diagnosis. This issue is crucial in multifactorial diseases like atherosclerosis, where the use of statins has now shifted from 'treating hypercholesterolaemia' to 'treating the risk of adverse cardiovascular events'...

Accurate risk prediction for chronic kidney disease (CKD) progression can inform the patient-provider dialogue, and provide actionable thresholds for key clinical decisions. In 2011, we developed the kidney failure risk equations (KFREs) to predict the risk of kidney failure requiring dialysis or transplant in patients with CKD. Subsequently, the KFREs have been extensively validated, and have now been proven accurate in multiple continents, ethnicities and disease-specific subpopulations. They can discriminate progressors from non-progressors, and are well calibrated and easy to use...

Recent studies suggest that the concentration and genotype of vitamin D binding protein (VDBP) are important factors that determine the bioavailability of 25-hydroxyvitamin D [25(OH)D] in blood. Accumulating data indicate that, e.g., in pregnant women, hemodialysis patients, chronic kidney disease, liver failure, and bladder and pancreatic cancers, the measurement of free 25(OH)D in serum provides more relevant diagnostic information than measurement of total 25(OH)D. The aim of this study was to develop and validate an ELISA for direct measurement of free 25(OH)D in serum...

REVIEW

Focal segmental glomerulosclerosis (FSGS) represents the most common primary glomerular disease responsible for the development of end-stage renal disease (ESRD) in the United States (US). The disease progresses from podocyte injury to chronic kidney disease (CKD), ultimately leading to total nephron degeneration. Extensive basic science research has been conducted to unwind the mechanisms of FSGS and, with those insights, understand major contributors of CKD in general. As a result, several putative molecules and pathways have been studied, all implicated in the disease; some serve, in addition, as early biomarkers...
