BACKGROUND: Not only is there a limited number of studies on the effects of vasodilator β-blocker (VBB) therapy on kidney function - specifically, glomerular filtration rate (GFR), serum creatinine (sCr) and proteinuria - but of those that have been reported, the results are mixed. This meta-analysis seeks to assess the efficacy of VBBs on selected renal parameters in hypertensive patients. METHODS: We conducted a meta-analysis of any prospective trial that provided both baseline and follow-up of at least 4 weeks of VBB therapy - carvedilol, labetalol, dilevalol, nebivolol and celiprolol in patients with hypertension...

Previously, we have demonstrated that the seeds of Euterpe oleracia Mart. (açaí) are rich in polyphenols with antihypertensive and antioxidant properties. This study evaluated the renal protective effects of the hydroalcoholic extract obtained from the seeds of açaí (ASE) fruits in two-kidney, one-clip (2K1C) renovascular hypertension. Young male Wistar rats were used to obtain 2K1C and sham groups. Animals received ASE (200 mg/(kg·day) in drinking water) or vehicle for 40 days. We evaluated serum and urinary parameters, renal structural changes, and oxidative status...

BACKGROUND: The urine albumin/creatinine ratio (ACR) test is used to screen patients with chronic diseases, such as diabetes, hypertension and cardiovascular diseases that put them at an increased risk of developing kidney disease. Here, we evaluated the performance of the URiSCAN 2 ACR Strip (URiSCAN; YD diagnostics, Yongin, Korea), a semiquantitative point-of-care testing (POCT) assay, and we compared to an existing POCT assay and a quantitative assay. MATERIALS AND METHODS: A total of 1,020 random urine specimens were analyzed using the semiquantitative URiSCAN 2 ACR Strip and semiquantitative CLINITEK Microalbumin 2 Strip (CLINITEK; Siemens, New York, USA)...

BACKGROUND: Using change in estimated glomerular filtration rate (eGFR) based on creatinine concentration as a surrogate outcome in clinical trials of chronic kidney disease has been proposed. Risk for end-stage renal disease (ESRD) and all-cause mortality associated with change in concentrations of other filtration markers has not been studied in chronic kidney disease populations. STUDY DESIGN: Observational analysis of 2 clinical trials. SETTING & PARTICIPANTS: Participants in the MDRD (Modification of Diet in Renal Disease; n=317) Study and AASK (African American Study of Kidney Disease and Hypertension; n=373)...

BACKGROUND: Relationships between early kidney disease, neurocognitive function, and brain anatomy are poorly defined in African Americans with type 2 diabetes mellitus (T2DM). STUDY DESIGN: Cross-sectional associations were assessed between cerebral anatomy and cognitive performance with estimated glomerular filtration rate (eGFR) and urine albumin-creatinine ratio (UACR) in African Americans with T2DM. SETTING & PARTICIPANTS: African Americans with cognitive testing and cerebral magnetic resonance imaging (MRI) in the African American-Diabetes Heart Study Memory in Diabetes (AA-DHS MIND; n=512; 480 with MRI) and Action to Control Cardiovascular Risk in Diabetes (ACCORD) MIND (n=484; 104 with MRI) studies...

BACKGROUND AND AIM: Patients with chronic kidney disease (CKD) have an increased risk of adverse cardiovascular outcomes after non-ST elevation acute coronary syndrome (NSTEACS). However, the information available on this specific population, is scarce. We evaluate the impact of CKD on long-term prognosis in patients with NSTEACS managed with invasive strategy. METHODS: We conduct a prospective registry of patients with NSTEACS and coronary angiography. CKD was defined as a glomerular filtration rate < 60ml/min/1,73m(2)...

No data are available about the impact of pregnancy on the long-term outcome of lupus nephritis. Thirty-two women with lupus nephritis with a 10-year follow-up after their first pregnancy ("women who gave birth") and 64 matched controls with the same follow-up and who never had pregnancies ("controls") were compared for the occurrence of SLE flares, chronic kidney disease (CKD), and SLICC/ACR Damage Index (SDI) in the post pregnancy period. The same evaluations were done before and after pregnancy in women who gave birth...

COMMENT
Maria D Sanchez-Niño, Alberto Ortiz
In this issue of CKJ, McQuarrie et al. have explored the relationship between socioeconomic status and outcomes among Scottish patients with a renal biopsy diagnosis of primary glomerulonephritis. Patients in the lower socioeconomic category had a twofold higher risk of death. No significant differences were observed on progression to end-stage renal disease (ESRD) requiring renal replacement therapy (RRT), suggesting that overall medical management was appropriate for all socioeconomic categories. The findings are significant since they come from an ethnically homogeneous population with free access to healthcare; they also relate to a specific aetiology of chronic kidney disease (CKD) expected to be less dependent on unhealthy lifestyles than other more frequent aetiologies that dominate studies of CKD in general, such as diabetic or hypertensive nephropathy...

The appropriate target for BP in patients with CKD and hypertension remains uncertain. We report prespecified subgroup analyses of outcomes in participants with baseline CKD in the Systolic Blood Pressure Intervention Trial. We randomly assigned participants to a systolic BP target of <120 mm Hg (intensive group; n=1330) or <140 mm Hg (standard group; n=1316). After a median follow-up of 3.3 years, the primary composite cardiovascular outcome occurred in 112 intensive group and 131 standard group CKD participants (hazard ratio [HR], 0...

Coarctation of the aorta is an uncommon cause of treatment-resistant hypertension in adults. It is typically detected and treated in infancy or childhood with surgical or endovascular procedures. Most cases of recurrence of coarctation after repair occur in childhood or early adulthood; recurrence in older persons (>70 years) has rarely been reported. A 73-year-old woman was referred to us for the management of treatment-resistant hypertension accompanied by symptoms of claudication and headaches, which had resulted in multiple emergency room visits...

BACKGROUND: There is vast evidence that the renin-angiotensin system is not the sole determinant of blood pressure (BP) elevation in human renovascular hypertension or the relevant experimental models. This study tested the hypothesis that kidney deficiency of 20-hydroxyeicosatetraenoic acid (20-HETE), a product of cytochrome P450 (CYP)-dependent ω-hydroxylase pathway of arachidonic acid metabolism, is important in the pathophysiology of the maintenance phase of 2-kidney, 1-clip (2K1C) Goldblatt hypertension...

BACKGROUND: Glomerular hyperfiltration may contribute to the high incidence of renal disease in Obese African Americans essential hypertensive (ObAAEH) patients, but the precise mechanisms responsible for renal injury have not been elucidated. Mitochondria are important determinants of renal injury in hypertension, and increased levels of mitochondrial DNA (mtDNA) in the urine may indicate renal mitochondrial injury. We hypothesized that urine mtDNA copy numbers would be higher in ObAAEH compared to Caucasian essential hypertensive (CEH) patients...

BACKGROUND: Better risk assessment tools are needed to predict post-transplantation diabetes mellitus (PTDM). Using analytic morphomic measurements from computed tomography (CT) scans, we aimed to identify specific measures of body composition associated with PTDM. METHODS: We retrospectively reviewed 99 non-diabetic kidney transplant recipients who received pre-transplant CT scans at a single institution between 1/2005 and 5/2014. Analytic morphomic techniques were used to measure abdominal adiposity, abdominal size, and psoas muscle area and density, standardized by gender...

The response of nutrient status and biochemical processes in (i) Wistar and (ii) spontaneously hypertensive (SHR) rats upon dietary intake of selenium- (Se-) enriched defatted rapeseed (DRS) and/or vitamin E fortification was examined to assess the health benefit of DRS in animal nutrition. Twenty-four individuals of each type of rat were used: The control group was fed with an untreated diet (Diet A). In Diets B and C, soybean meal was replaced with defatted DRS, which comprised 14% of the total diet. The selenized DRS application resulted in ~3-fold increase of Se content in the diet...

REVIEW
Baris Afsar
Copeptin is derived from the cleavage of the precursor of arginine vasopressin (AVP), produced in an equimolar ratio in hypothalamus and processed during axonal transport AVP is an unstable peptide and has a short half-life of 5-20 min. Unlike AVP, copeptin is a stable molecule and can easily be measured. Recent evidence suggest that increased copeptin levels have been associated with worse outcomes in various clinical conditions including chronic kidney disease (CKD) and hypertension. In this review, the data regarding copeptin with kidney function (evaluated as glomerular filtration rate, increased albumin/protein excretion or both) and hypertension with regard to performed studies, prognosis and pathogenesis was summarised...

Chronic kidney disease (CKD) has a prevalence of approximately 13% and is most frequently caused by diabetes and hypertension. In population studies, CKD etiology is often uncertain. Some experimental and observational human studies have suggested that high-protein intake may increase CKD progression and even cause CKD in healthy people. The protein source may be important. Daily red meat consumption over years may increase CKD risk, whereas white meat and dairy proteins appear to have no such effect, and fruit and vegetable proteins may be renal protective...

As there may be an association between within-visit blood pressure (BP) variability and cardiovascular disease (CVD), we investigated the clinical significance of this BP variability in non-dialysis chronic kidney disease (CKD) patients. MATERIALS AND METHODS: According to the median of coefficient of variation (CV) of three systolic BP (SBP) readings within a single visit, we divided hypertensive patients with stage G1-4 CKD already treated with antihypertensive therapy into the high SBP-CV group and the low SBP-CV group...

Selenium (Se) is an essential trace element involved in several biological pathways, naturally found in rocks, soils, and food. Even though the daily requirement of Se is achieved through a balanced diet, the use of Se supplements has been frequent. Due to the risk of toxic effects of having Se in excess, supplementation is still under debate. The aim was to evaluate the effects of long-term Se supplementation upon systolic blood pressure (SBP) and redox status of rats exposed to sodium selenite. Male Wistar rats were exposed to 2 and 6 mg/L of sodium selenite in drinking water for 85 days...
