METHODS: In this prospective cohort study, 1700 Asian people with Type 2 diabetes were followed for a mean of 6.3 years in a regional hospital in Singapore. Incident end-stage renal disease was identified by linkage with a national renal registry. The association of baseline fibroblast growth factor 21 levels with risk of progression to end-stage renal disease was studied using survival analyses...

To elucidate the association between renal hyperfiltration (RHF) and incident proteinuria, the data from 11,559,520 Korean adults who had undergone health screenings ≥ 3 times between 2009 and 2014 and had glomerular filtration rate (GFR) ≥60 mL/min/1.73m2 and negative dipstick test for proteinuria at baseline, were retrospectively analyzed. GFR was estimated with the Chronic Kidney Disease Epidemiology Collaboration equation based on serum creatinine, and RHF was defined as GFR >95th percentile adjusted for sex, age, body size, and diabetes and/or hypertension medication...

BACKGROUND: To investigate the related influencing factors of abnormal renal function in elderly in patients with type 2 diabetes mellitus (T2DM) and their clinical significance. METHODS: The clinical data of elderly T2DM patients hospitalized in Beijing Luhe Hospital from January 2013 to June2016 were retrospectively analyzed. According to their glomerular filtration rate (GFR) levels, these patients were divided into GFR ≥90 mL/min/1.73m2 group (Group A), GFR =60-90 mL/min/1...

INTRODUCTION: Chronic serum uric acid elevation (SUA) is known to be induced by dyslipidemia, hypertension, inflammation, and insulin resistance. Therefore, it has been associated with higher risk for coronary artery disease and cardiovascular mortality. Also, increased levels of SUA have been associated with regional arterial stiffness, assessed by pulse wave velocity (PWV). AIMS: To evaluate the relationships of PWV, SUA and different metabolic parameters in essential hypertensive patients...

BACKGROUND: Chronic kidney disease (CKD) is very common now and is associated with high overall and cardiovascular mortality. Numerous studies have reported that abdominal obesity is a risk factor for cardiovascular mortality. We investigated the link between sagittal abdominal diameter (SAD) and Framingham risk score in non-dialysis CKD patients. METHODS: In a cross-sectional study, we enrolled 307 prevalent non-dialysis CKD patients (175 males, aged 50.7 ± 17...

Crystallopathies are a heterogeneous group of diseases caused by intrinsic or environmental microparticles or crystals, promoting tissue inflammation and scarring. Certain proteins interfere with crystal formation and growth, e.g., with intrarenal calcium oxalate (CaOx) crystal formation, a common cause of kidney stone disease or nephrocalcinosis-related chronic kidney disease (CKD). We hypothesized that immunoglobulins can modulate CaOx microcrystal formation and crystal growth and that therefore, biological IgG-based drugs designed to specifically target disease modifying proteins would elicit a dual effect on the outcome of CaOx-related crystallopathies...

The estimated glomerular filtration rate (eGFR) is a predictor of important outcomes and its reduction has been associated with the risk of all-cause mortality in both general population and elderly patients. However while reduced renal function is common in older people, the best method for estimating GFR remains unclear, especially in an acute care setting. Most studies analyzing the accuracy of eGFR in the elderly were carried out in different heterogeneous settings. In this study, we compare the prognostic value of different formulas estimating GFR in predicting the risk of in-hospital morbidity and mortality within 3 months from discharge in elderly hospitalized patients...

PURPOSE: Chronic kidney disease (CKD) is a progressive condition characterized by irreversible loss of functional nephron mass due to variety of causes; an inevitable complication of CKD is metabolic bone disease, and this pathology is called as renal osteodystrophy (ROD). In this study, we aimed to determine the levels of serum sRANKL and intracellular NF-κB levels in peripheral blood osteoclast precursor cells in patients with stage 3 CKD. MATERIALS AND METHODS: Forty-one male patients aged 35-60 with CKD identified as stage 3 according to GFR calculated on the basis of creatinine values and 27 healthy male subjects with age ranging from 40 to 60 as control group were included in this study...

BACKGROUND/AIMS: Lung dysfunction associates with increased mortality but the impact of chronic kidney disease (CKD) is less clear. We evaluated lung function and its association with mortality among individuals with normal to severely reduced glomerular filtration rate (GFR). METHODS: 404 individuals representing GFR category G1 (n=31; GFR >90 mL/min/1.73 m2), G2 (n=46), G3 (n=33), G4 (n=49) and G5 (n=245; GFR< 15 mL/min/1.73 m2) underwent spirometry yielding lung function indices forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and peak expiratory flow (PEF)...

OBJECTIVES: Recent studies have demonstrated promising results regarding possible improvements in renal function after prebiotic, probiotic, and synbiotic supplementation. The aim of this review was to demonstrate whether such supplementation will improve renal profile indexes including glomerular filtration rate (GFR), creatinine, blood urea nitrogen (BUN), uric acid (UA), and urea. METHOD: The meta-analysis included all studies that examined the effect of prebiotic, probiotic, and synbiotic supplements on one or more renal function parameters and had a control group...

OBJECTIVES: The patient's body surface area serves as the traditional reference for the determination of systemic blood flow during cardiopulmonary bypass (CPB). New strategies refer to different algorithms of oxygen delivery. This study reports on the mixed venous oxygen saturation (Sv O2 ) as the target for systemic blood flow control. We hypothesise that an Sv O2 >75% (Sv O2 75) is associated with better preservation of renal function and improved short-term survival. METHODS: This retrospective, 10-year, observational study analysed 6945 consecutive cardiac surgical cases requiring CPB...

BACKGROUND: Fabry disease (FD) results from X-linked inheritance of a mutation in the GLA gene, encoding for alpha galactosidase A, and is characterized by heterogeneous clinical manifestations. Two phenotypes have been described "Classic" and "late onset" which cannot be predicted exclusively by genotype. The latter has been considered an attenuated form of the disease often affecting a single organ system commonly the heart. Recent studies have demonstrated that cardiac outcomes are similar in patients with classic and late onset mutations...

BACKGROUND: Sex-based disparities in liver transplantation (LT) are incompletely understood. We assessed the role of height, MELD, MELD-Na and exception points in the disparate access to LT. METHODS: Adults waitlisted for LT at Organ Procurement and Transplantation Network (OPTN) between 2002 and 2013 were included. Covariates associated with likelihood of LT were analyzed by Cox proportional model. In a separate cohort of waitlisted adults with glomerular filtration rate (GFR) measurement by iothalamate clearance (n=611), we determined the number of creatinine-derived MELD points in men vs women, across all ranges of GFR...

Insulin resistance (IR) is very common among chronic kidney disease (CKD) patients. Disturbance in mineral and bone metabolism (MBD) seems to play a role in the pathogenesis of insulin resistance. Fibroblast growth factor-23 (FGF23) is evolving as the most important link between MBD and many pathologic sequences of CKD. The aim was to evaluate IR in pre-dialysis CKD patients looking for a possible association to mineral metabolism among CKD patients. A total of 100 stage 3-5 CKD patients were selected beside 20 normal control subjects...

BACKGROUND: In patients with heart failure with preserved ejection fraction (HFpEF), worse kidney function is associated with worse overall cardiac mechanics. Right ventricular stroke work index (RVSWI) is a parameter of right ventricular function. The aim of our study was to determine the relationship between RVSWI and glomerular filtration rate (GFR) in patients with HFpEF. METHOD: This was a single-center cross-sectional study. HFpEF is defined as patients with documented heart failure with ejection fraction > 50% and pulmonary wedge pressure > 15 mm Hg from right heart catheterization...

INTRODUCTION: Chronic kidney disease (CKD) is a major health issue worldwide, which leads to end-stage renal failure and cardiovascular events. Neutrophil to lymphocyte ratio (NLR) is a surrogate marker of inflammation and has been widely studied in malignancies, hypertension, heart diseases, and vascular diseases. In this study, we aimed to investigate if NLR represents renal reserve and function after partial or radical nephrectomy. METHODS: We conducted a retrospective study consists of patients who had undergone radical/partial nephrectomy in our hospital and/or who admitted to urology and nephrology clinics as an outpatient...

BACKGROUND: Due to recent advances in endograft design and percutaneous access, technical success could be increased during endovascular aneurysm repair (EVAR). Beside EVAR, endovascular aneurysm sealing (EVAS) provides an alternative procedure to treat aneurysms. To compare the two methods, additional benchmark criteria should be evaluated: Screening time, dose area product (DAP), procedure time and contrast use. In this study these technical variables are analysed for EVAS vs. EVAR in comparable patient cohorts...
