BACKGROUND/AIMS: Temporary proteinuria post-exercise is common and is caused predominantly by renal haemodynamic alterations. One reason is up-regulation of angiotensin II (Ang II) due to the reducing effect of angiotensin-converting enzyme (ACE) inhibitors. However, another, ignored, reason could be the kininase effect of ACE inhibition. This study investigated how ACE inhibition reduces post-exercise proteinuria: by either Ang II up-regulation inhibition or bradykinin elevation due to kininase activity inhibition...

BACKGROUND/AIM: In clinical research setting, accurate and precise measurement of glomerular filtration rate (GFR) is essential to overcome the limitations of GFR estimation with equations, which are often unreliable. In recent decades, a method for measuring GFR by plasma clearance of iohexol, a non-ionic radiocontrast agent, was developed. To evaluate the safety of the procedure, we aimed to review all immediate adverse reactions that could be related to iohexol administration in our group's 25 years worth of experience...

BACKGROUND: Vancomycin-associated (VA) acute kidney injury (AKI) is being increasingly recognized. A distinct pattern of rapid rise in serum creatinine (sCr) during VA-AKI has occasionally been observed. However, such scenarios remain underreported. METHODS: We conducted an online survey at the American Society of Nephrology Communities forum and reviewed publications of VA-AKI via PubMed or Google searching for cases of precipitous AKI (those with rise in sCr ≥1...

BACKGROUND: Recent observational studies have shown that in chronic kidney disease (CKD) patients, a significantly smaller percentage of patients with an episode of acute kidney injury (AKI) have full recovery of renal function compared to those without CKD. However, precise mechanisms involved in the incomplete repair after AKI with preexisting CKD have not been completely ascertained. Here, we assessed the impact of preexisting CKD on the severity and recovery of AKI in a mouse model of 5/6 nephrectomy...

BACKGROUND: Acid-base disturbances are frequent in critically ill patients. Arterial blood gas (ABG) is the gold standard in the diagnosis of these disturbances, but it is invasive with potential hazards. For patients with a central venous catheter, venous blood gas (VBG) sampling may be an alternative, less-invasive diagnostic tool. However, the accuracy of a central VBG-based acid-base disorder diagnosis compared to an ABG is unknown. The primary objective of this study was to assess the accuracy of a central VBG-based acid-base disorder diagnosis compared to the "gold standard" ABG in critically ill patients...

BACKGROUND/AIMS: Acute kidney injury (AKI) biomarkers have been developed with the aim of being able to detect kidney damage earlier than the detection process based on serum creatinine levels. However, single time-point measurements appear to furnish insufficient information for detecting and predicting AKI in intensive care unit patients who are frequently affected by multiple and transient/persistent renal insults. We evaluated whether serial measurements enable the prediction of AKI outcomes in such patients...

BACKGROUND: Low mean arterial pressure (MAP) is a well-known risk factor for postoperative acute kidney injury (AKI), but probably it is not the sole hemodynamic parameter that can influence the development of renal failure. There are data in cardiac patients supporting the role of renal venous congestion in the development of AKI. The aim of our study was to determine a combination of factors best predicting the development of AKI. METHODS: Data were collected prospectively for adult patients admitted after major abdominal surgery to 9 Hungarian intensive care units...

BACKGROUND: Arterial stiffness (AS) and vascular calcification are significantly related to a high cardiovascular mortality risk in hemodialysis (HD) patients. Intravenous sodium thiosulfate (IV STS) can prevent and delay the vascular calcification progression in uremic states; however, the STS effect on AS has not been assessed. This study aimed to evaluate the STS efficacy on vascular calcification and AS in HD patients. METHODS: Fifty HD patients with abnormal AS, as measured via the cardio-ankle vascular index (CAVI ≥8), were prospectively randomized to open-label 12...

BACKGROUND AND AIMS: Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) estimations of glomerular filtration rate (eGFR), compared to modification of diet in renal disease (MDRD), have superior performance in predicting renal, cardiovascular and mortality events. Cystatin-C further improves prediction. Our primary aim was to assess the change in prevalence and classification of CKD in converting from MDRD to CKD-EPI in an unselected primary care CKD population. Our secondary aims were to determine the eligibility for cystatin-C testing based on National Institute for Health and Care Excellence guidance and the associated costs...

BACKGROUND: Renal fibrosis is a common outcome of nearly all kinds of chronic kidney disease (CKD) and eventually progresses to end-stage renal disease. The identification of an optimal biomarker of renal fibrosis to replace the invasive renal biopsy will have important clinical implications. METHODS: We isolated urinary exosomes from 50 participants and examined the exosomal protein content and particle number in 38 CKD patients with different degrees of renal fibrosis and in 12 normal individuals...

BACKGROUND: Cinacalcet could decrease serum calcium, phosphate, and parathyroid hormone (PTH) in previous meta-analyses. However, the effect of cinacalcet on the new biomarkers such as fibroblast growth factor-23 (FGF-23), bone markers, and vascular calcification are still unestablished. We conducted a meta-analysis to examine the effects of cinacalcet on all laboratory and clinical spectrums of chronic kidney disease-mineral bone disorders (CKD-MBD). METHODS: A systematic literature search was conducted in MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, and Clinical Trials...

BACKGROUND/AIMS: Variability in the grade of atherosclerosis among patients with chronic kidney disease (CKD) could affect the ultrasound measurements of intima media thickness (IMT). We sought to investigate IMTs of carotid (cIMT) and femoral (fIMT) arteries in CKD patients and assess the degree of their correlation with histopathological atherosclerosis. METHODS: Eighty-nine out of 99 enrolled subjects completed this study. The subjects were divided into 3 groups: 34 patients with CKD (Case group), 31 with coronary artery disease undergoing coronary artery bypass graft (CABG, positive control group), and 24 healthy kidney donors (negative control group)...
