BACKGROUND: 2 valid and reliable estimated glomerular filtration rate (GFR) equations for the pediatric population have been developed from directly measured GFR data in the Chronic Kidney Disease in Children (CKiD) cohort: the full CKiD and bedside CKiD equations. Although adult GFR estimating equations replicate relationships of measured GFR with biomarkers, it is unclear whether similar patterns exist among children and adolescents with chronic kidney disease (CKD). STUDY DESIGN: Prospective cohort study in children and adolescents...

Arterial stiffness can enhance cardiovascular risk by increasing atherogenesis or adverse hemodynamic effects. We examined whether the arterial stiffness markers of aortic pulse wave velocity (PWV) and the augmentation index (AIx) are independently associated with carotid artery intima-media thickness (IMT) and plaque in patients with rheumatoid arthritis (RA). PWV and AIx were determined by brachial oscillometry using the Mobil-O-Graph® system and carotid IMT and plaque by ultrasound in 194 consecutive RA patients without established cardiovascular disease, chronic kidney disease, and diabetes at disease onset...

ACE inhibitors are considered first line of treatment in patients with many forms of chronic kidney disease (CKD). Other antihypertensives such as calcium channel blockers achieve similar therapeutic effectiveness in attenuating hypertension-related renal damage progression. Our objective was to explore the value of positron emission tomography (PET) imaging of renal AT1 receptor (AT1R) to guide therapy in the 5/6 subtotal-nephrectomy (Nx) rat model of CKD. Ten weeks after Nx, Sprague-Dawley rats were administered 10mg/kg/d enalapril (NxE), 30mg/kg/d diltiazem (NxD) or left untreated (Nx) for an additional 8-10 weeks...

Hyperhomocysteinemia has attracted a lot of attention in renal patients, not only because of its close relationship with renal function but also because it has been implicated as an independent cardiovascular risk factor in these patients. An increased level of C-reactive protein (CRP) has been reported to be a strong predictor of cardiovascular mortality in hemodialysis (HD) patients. The aim of this study was to assess the association between homocysteine (Hcy) and highly sensitive CRP (hsCRP) in cardiovascular risk prediction in children with chronic kidney disease (CKD) on HD...

BACKGROUND: New surgical techniques for nephrectomy mainly related to early diagnosis made possible by advances in imaging studies have been developed in recent decades. However, postoperative renal dysfunction is a constant concern because of the major problems faced by healthcare services and by the patients themselves. To assess risk factors for developing acute renal failure (ARF) in patients submitted to nephrectomy in a university hospital. METHODS: Seventy-seven patients submitted to nephrectomy for benign and malignant diseases in a university hospital were evaluated in respect to preoperative and postoperative creatinine clearance...

BACKGROUND: Serum calcium concentration (Ca) plays an essential role in a vascular muscle tone and myocardial contractility. Previously, we showed that acutely lowering Ca by hemodialysis reduced arterial stiffness. Cinacalcet is a calcimimetic that lowers Ca and parathyroid hormone (PTH). The aim of the present study was to examine whether acute lowering of Ca by cinacalcet improves vascular stiffness and myocardial diastolic dysfunction. METHOD: This is a double-blinded randomized placebo-controlled crossover study that included 21 adult patients with end-stage kidney disease undergoing chronic hemodialysis...

BACKGROUND: Due to loss of hormonal protective effects, postmenopausal women have an increased cardiovascular (CV) risk. Chronic kidney disease (CKD) is a well-established risk factor for CV disease, but little is known whether mild-to-moderate kidney dysfunction is associated with atherosclerosis burden in the postmenopausal asymptomatic women. MATERIALS AND METHODS: Subclinical atherosclerosis was evaluated in 125 postmenopausal women with no clinical form of atherosclerosis, by carotid and femoral ultrasonography, ankle-brachial index (ABI), and flow-mediated dilation (FMD)...

High blood pressure is a major risk factor for cardiovascular disease. The 2013 ACC/AHA Lifestyle Management Guideline recommends counseling pre-hypertensive and hypertensive patients to reduce sodium intake. Population sodium reduction efforts have been introduced in recent years, and dietary guidelines continued to emphasize sodium reduction in 2010 and 2015. The objective of this analysis was to determine changes in primary health care providers' sodium-reduction attitudes and counseling between 2010 and 2015...

REVIEW
Diego F Marquez, Gema Ruiz-Hurtado, Luis Ruilope
Arterial hypertension and chronic kidney disease (CKD) are intimately related. The control of blood pressure (BP) levels is strongly recommended in patients with CKD in order to protect the kidney against the accompanying elevation in global cardiovascular (CV) risk. Actually, the goal BP in patients with CKD involves attaining values <140/90 mmHg except if albuminuria is present. In this case, it is often recommended to attain values <130/80 mmHg, although some guidelines still recommend <140/90 mmHg...
