BACKGROUND: Arterial stiffness is linked to the progression of atherosclerosis, while activation of vitamin D receptor exerts favorable cardiovascular effects in patients with renal insufficiency. In this study, we investigated the effects of oral treatment with paricalcitol, a potent vitamin D receptor activator on arterial stiffness and osteopontin, a marker of atherosclerosis, in hypertensive patients with chronic kidney disease (CKD) and secondary hyperparathyroidism. METHODS: We followed up 29 treated hypertensive patients (mean age 74...

OBJECTIVE: Multiple studies have shown that gut microbes contribute to atherosclerosis, and there is mounting evidence that microbial metabolism of dietary nutrients influences pathophysiology. We hypothesized that indole- and phenyl-derived metabolites that originate solely or in part from bacterial sources would differ between patients with advanced atherosclerosis and age- and sex-matched controls without clinically apparent atherosclerosis. METHODS: Plasma from the advanced atherosclerosis cohort (n = 100) was from patients who underwent carotid endarterectomy, open infrainguinal leg revascularization, or major leg amputation for critical limb ischemia...

Cardiovascular diseases are the leading causes of mortality in patients with chronic kidney disease. Nitric oxide has a critical role in both endothelial dysfunction and the atherosclerosis process. We aimed to investigate the relationships between serum asymmetric dimethyl arginine (ADMA), LOX-1, and Apelin-13 levels, which are known to act over nitric oxide with endothelial dysfunction and cardiac morphology as well as with each other in hemodialysis patients. The study comprised a total of 120 patients (53 females and 67 males) receiving hemodialysis three times a week for at least 6 months and an age-gender matched control group (55 females and 58 males)...

BACKGROUND: Urinary microRNAs (miRNAs) play a role in the pathogenesis of chronic kidney disease (CKD). AIM: To identify the expression of urinary miR-377 and miR-216a in 50 children and adolescents with type 1 diabetes (T1DM) compared with 50 healthy controls and assess their relation to the degree of albuminuria, glycemic control and carotid intimal thickness (CIMT) as an index of atherosclerosis. METHODS: Diabetic subjects were divided into normoalbuminuric and microalbuminuric groups according to urinary albumin creatinine ration (UACR)...

Atherosclerotic cardiovascular disease is a major complication of chronic kidney disease (CKD). CKD leads to uremia, which modulates the phenotype of aortic smooth muscle cells (SMCs). Phenotypic modulation of SMCs plays a key role in accelerating atherosclerosis. We investigated the hypothesis that uremia potentiates neointima formation in response to vascular injury in mice. Carotid wire injury was performed on C57BL/6 wt and apolipoprotein E knockout (Apoe (-/-)) mice two weeks after induction of uremia by 5/6 nephrectomy...

Atherosclerosis is frequently present in patients with chronic kidney disease (CKD) treated with dialysis. We evaluated the association between residual renal function (RRF), phosphate level, inflammation and other risk factors in carotid modeling as a marker of early atherosclerosis in peritoneal dialysis (PD) compared with hemodialysis (HD) patients. We studied 39 stable PD and 53 HD patients on renal replacement therapy (RRT) for 3 to 36 months duration. B-mode ultrasonography was used to determine carotid artery intima media thickness (CIMT)...

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...

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)...

Uric acid is the final end-product of purine metabolism and 70% of it is excreted through the kidneys. Chronic hyperuricemia can easily cause gout and meanwhile may affect the kidneys and cardiovascular system. In recent years,the incidences of hyperuricemia and gout have gradually increased. This article summarizes the correlation of hyperuricemia with hyperuricemic nephropathy,gouty arthritis,non-alcoholic fatty liver disease,and carotid atherosclerosis and the role of color Doppler ultrasound in the diagnosis of these lesions...

PURPOSE OF REVIEW: Adiponectin is an adipokine with anti-inflammatory, antioxidant, antiatherogenic, pro-angiogenic, vasoprotective and insulin-sensitizing properties. Several factors may influence adiponectin levels, such as genetic polymorphisms, obesity / body fat distribution, diet and exercise as well as cardiovascular risk factors such as sleep deprivation and smoking as well as medications. Adiponectin has been proposed as a potential prognostic biomarker and a therapeutic target in patients with cardiometabolic diseases...

BACKGROUND AND AIMS: Circulating soluble TNF-like weak inducer of apoptosis (sTWEAK) concentrations are related to the presence of chronic kidney disease (CKD) and cardiovascular disease (CVD). However, there are no data regarding the potential association between sTWEAK and atheromatosis progression in patients free of cardiovascular events. METHODS: Soluble TWEAK serum concentration was measured in 702 CKD patients without any previous CV event from The National Observatory of Atherosclerosis in Nephrology (NEFRONA) Study...

Thrombosis is a common complication of chronic kidney disease (CKD), but the causes and mechanisms of CKD-associated thrombosis are not well clarified. Here, we show that platelet activity is remarkably enhanced in CKD mice, with increase of serum indoxyl sulfate (IS), a typical uremic toxin, which cannot be effectively cleared by routine dialysis. Ex vivo and in vitro experiments reveal that IS displays a distinct ability to enhance platelet activities, including elevated response to collagen and thrombin, increases in platelet-derived microparticles, and platelet-monocyte aggregates...

Advanced glycation end-products (AGEs) are increased and predict mortality in patients with chronic kidney disease (CKD) who are undergoing hemodialysis, irrespective of the presence of type 2 diabetes. However, little information exits about the relationship between AGEs and subclinical atherosclerosis at the early stages of CKD. A case-control study was performed including 87 patients with mild-to-moderate stages of CKD (glomerular filtration rate from 89 to 30 ml/min/per 1.73m2) and 87 non-diabetic non-CKD subjects matched by age, gender, body mass index, and waist circumference...

BACKGROUND AND AIMS: Although comprehensive risk factor modification is recommended, a uniform management strategy does not necessarily prevent secondary events in patients with coronary artery disease (CAD). Therefore, identification of high-risk patients who may benefit from more intensive interventions may improve prognosis. Carotid ultrasound can reliably identify systemic atherosclerosis, and carotid plaque and intima-media thickness (IMT) are known independent risk factors for CAD...

BACKGROUND: Monocytic products, such as lipoprotein-associated phospholipase A2 (Lp-PLA2), may participate in the development of atherosclerosis. Heterogeneity of monocytes is widely acknowledged. Classical, intermediate, and non-classical subsets can be discerned. Recently, an inflammatory, pro-atherogenic monocyte population could be identified in hemodialysis patients. In this study, we investigated the expression of Lp-PLA2 on leucocytes and different monocyte subpopulations and their possible role in uremia, inflammation, and atherosclerosis...

BACKGROUND AND AIMS: A high prevalence of atherosclerotic lesions characterizes patients with chronic kidney disease, though there is little data on the relationship between kidney function and atherosclerotic changes in the healthy population or in people with no known renal impairment. The aim of our study was to analyze, in a comprehensive general population with no known kidney disease, the relationship between renal function and subclinical carotid atherosclerotic damage. METHODS AND RESULTS: A general real-life population of 611 participants (233 males and 378 females; age ≥18 years) with no known kidney failure was selected for the study...

BACKGROUND AND OBJECTIVES: Atherosclerotic changes of arteries are the leading cause for deaths in cardiovascular disease and greatly impair patient's quality of life. Sphingosine-1-phosphate (S1P) is a signaling sphingolipid that regulates potentially pro-as well as anti-atherogenic processes. Here, we investigate whether serum-S1P concentrations are associated with peripheral artery disease (PAD) and carotid stenosis (CS). METHODS AND RESULTS: Serum was sampled from blood donors (controls, N = 174) and from atherosclerotic patients (N = 132) who presented to the hospital with either clinically relevant PAD (N = 102) or CS (N = 30)...

OBJECTIVE: Irisin is a muscle-secreted protein released into the circulation by cleavage of fibronectin type III domain containing protein 5(FNDC5). Since its discovery in 2012, it has been the subject of many researches due to its physiological role. It is believed that understanding irisin's function may be the key to comprehend many diseases and their development. The aim of this study is to perform a systematic review in order to establish whether there is an association of irisin's levels with obesity, diabetes mellitus, non-alcoholic steatohepatitis, chronic kidney disease and cancer in terms of prognosis...

BACKGROUND: Epidemiological studies have shown an inverse relationship between vitamin D levels and cardiovascular diseases. However, this does not infer a causal relationship between the two. Chronic kidney disease (CKD) patients have a high prevalence of vitamin D deficiency and carotid atherosclerosis. Therefore, in this study we have aimed to determine the association between serum 25-hydroxyvitamin D levels and carotid atherosclerosis in the CKD population. METHODS: 100 CKD stage 3-4 patients were included in the study...
