Abstract
Background This analysis was designed to investigate the relationship between drug application and mortality rate in Chinese older coronary artery disease (CAD)/chronic heart failure (CHF) patients with and without low glomerular filtration rate (GFR). Methods All 1050 Chinese hospitalized patients with diagnosed CAD were included in this analysis, and Cox Regression was used to analyze the relationship between drug application and mortality rate after multivariate adjustment. Low GFR was defined as GFR < 60 ml/min/1.73m2. Results There were 372 patients (35.4%) with low GFR in patients with CAD (1050 patients), and 168 patients (51.4%) in patients with CHF (327 patients). In CAD patients without low GFR, clopidogrel [P = 0.028, odds ratio (OR): 0.620, 95% confidence interval (CI): 0.404–0.951] rather than aspirin (P = 0.173) was significantly associated with lower mortality rate. Statins (P < 0.001, OR: 0.287, 95% CI: 0.180–0.456) were significantly associated with lower mortality rate. In CAD patients with low GFR, aspirin, clopidogrel and statins had no significant relationship with mortality rate (P > 0.05 for all). In CHF patients without low GFR, statins were significantly associated with lower mortality rate (P < 0.001, OR: 0.220, 95% CI: 0.098–0.490). In CHF patients with low GFR, statins had no significant relationship with mortality rate (P > 0.05 for all). Conclusion Clopidogrel but not aspirin was beneficial in Chinese older CAD patients without low GFR rather than those with low GFR, and statins benefited for Chinese older CAD/CHF patients without low GFR rather than those with low GFR. These discoveries might offer some help for the therapy of Chinese older patients with cardiovascular/renal diseases.

Abstract
In Taiwan, the prevalence of hyperlipidemia increased due to lifestyle and dietary habit changes. Low density lipoprotein cholesterol (LDL-C) and non-high density lipoprotein cholesterol (non-HDL-C) are all significant predicting factors of coronary artery disease in Taiwan. We recognized that lipid control is especially important in patients with existed atherosclerotic cardiovascular diseases (ASCVD), including coronary artery disease (CAD), ischemic stroke and peripheral arterial disease (PAD). Because the risk of ASCVD is high in patients with diabetes mellitus (DM), chronic kidney disease (CKD) and familial hypercholesterolemia (FH), lipid control is also necessary in these patients. Lifestyle modification is the first step to control lipid. Weight reduction, regular physical exercise and limitation of alcohol intake all reduce triglyceride (TG) levels. Lipid-lowering drugs include HMG-CoA reductase inhibitors (statins), cholesterol absorption inhibitors (ezetimibe), proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, nicotinic acids (niacin), fibric acids derivatives (fibrates), and long-chain omega-3 fatty acids. Statin is usually the first line therapy. Combination therapy with statin and other lipid-lowering agents may be considered in some clinical settings. For patients with acute coronary syndrome (ACS) and stable CAD, LDL-C < 70 mg/dL is the major target. A lower target of LDL-C <55 mg/dL can be considered in ACS patients with DM. After treating LDL-C to target, non-HDL-C can be considered as a secondary target for patients with TG ≥ 200 mg/dL. The suggested non-HDL-C target is < 100 mg/dL in ACS and CAD patients. For patients with ischemic stroke or transient ischemic attack presumed to be of atherosclerotic origin, statin therapy is beneficial and LDL-C < 100 mg/dL is the suggested target. For patients with symptomatic carotid stenosis or intracranial arterial stenosis, in addition to antiplatelets and blood pressure control, LDL-C should be lowered to < 100 mg/dL. Statin is necessary for DM patients with CV disease and the LDL-C target is < 70 mg/dL. For diabetic patients who are ≥ 40 years of age, or who are < 40 years of age but have additional CV risk factors, the LDL-C target should be < 100 mg/dL. After achieving LDL-C target, combination of other lipid-lowering agents with statin is reasonable to attain TG < 150 mg/dL and HDL-C >40 in men and >50 mg/dL in women in DM. LDL-C increased CV risk in patients with CKD. In adults with glomerular filtration rate (GFR) < 60 mL/min/1.73m2 without chronic dialysis (CKD stage 3-5), statin therapy should be initiated if LDL-C ≥ 100 mg/dL. Ezetimibe can be added to statin to consolidate the CV protection in CKD patients. Mutations in LDL receptor, apolipoprotein B and PCSK9 genes are the common causes of FH. Diagnosis of FH usually depends on family history, clinical history of premature CAD, physical findings of xanthoma or corneal arcus and high levels of LDL-C. In addition to conventional lipid lowering therapies, adjunctive treatment with mipomersen, lomitapide, or PCSK9 inhibitors become necessary to further reduce LDL-C in patients with FH. Overall, these recommendations are to help the health care professionals in Taiwan to treat hyperlipidemia with current scientific evidences. We hope the prescription rate of lipid lowering drugs and control rate of hyperlipidemia in high risk patients could be increased by implementation of the clinical guidelines. The major purpose is to improve clinical outcomes of these high risk patients through the control of hyperlipidemia.

Abstract
INTRODUCTION The prevalence of chronic kidney disease (CKD), a risk factor for cardiovascular disease (CVD), is increasing worldwide. Statin treatment, the cornerstone of prevention or treatment of CVD, might have beneficial effects on urine protein excretion and renal function as determined by the glomerular filtration rate, whereas it might protect from acute kidney injury (AKI), mainly due to contrast-induced AKI. These beneficial effects on CKD may not be drug class effects; specific statins at specific doses may help prevent CKD deterioration and reduce CVD risk. We analysed all statin studies that had renal and CVD endpoints as main outcome measures. MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials were searched up to February 2015. AREAS COVERED We consider the effects of statins on microalbuminuria, proteinuria, glomerular filtration rate, AKI associated with angiography or percutaneous coronary intervention and on CVD event rates in patients with CKD. EXPERT OPINION Current evidence points towards the need to prescribe high-potency statins in patients with CKD, before a major decline in kidney function occurs. This may reduce CVD risk and delay the progress of CKD. Administration of either atorvastatin or rosuvastatin can prevent contrast-induced AKI before angiography or percutaneous coronary intervention. The combination of simvastatin + ezetimibe may decrease vascular events in patients with advanced CKD.

Abstract
BACKGROUND The objective of this nationwide retrospective cohort study was to examine the renal outcomes of HMG-CoA reductase inhibitor (statin) initiators. METHODS The patients who started to take statins with high cholesterol-lowering efficacy (atorvastatin and rosuvastatin) and low efficacy (lovastatin, simvastatin, pravastatin, and fluvastatin) between 1 January 2001 and 31 December 2008 were identified from the Taiwan National Health Insurance claims database. The outcome of interest was severe renal failure, defined as the composite endpoint of hemodialysis, peritoneal dialysis, and kidney transplantation. A proportional hazard regression model was applied to estimate the incidence ratio between the two groups, adjusted for the propensity scores based upon baseline characteristics. RESULTS Among of the 26,007 and 42,249 statin initiators, the crude incidence rate for developing severe renal failure was 0.65 and 0.46 per 100 person-years for the high-efficacy and low-efficacy groups, respectively. Despite that these two groups had comparable risk for myocardial infarction (hazard ratio: 1.06, 95%CI: 0.92–1.21), there was a 13% increased hazard for developing severe renal failure in the rosuvastatin and atorvastatin initiators (hazard ratio: 1.13, 95%CI: 1.02–1.26). The increased risk associated with these two statins was consistent across different risk groups (diabetes, chronic kidney disease, and ischemic heart disease). CONCLUSIONS Statins with high cholesterol-lowering efficacy might increase the risk for developing severe renal failure. An alternative explanation is that the renal risk cannot be ameliorated as much as cardiovascular risk. Further follow-up studies or meta-analyses are needed to solve the controversy.

Abstract
BACKGROUND The natural history of patients commencing dialysis in East Yorkshire is not well characterised and there is little convincing evidence which has studied the impact of potential factors prior to commencement of renal replacement therapy (RRT) at predicting mortality during dialysis. The aim of this study was to examine the previously published 5-year data on end stage renal disease and co-morbid risk factors for mortality at 10 years. METHODS An observational cohort study of subjects commencing dialysis in 2001/02 in East Yorkshire with a mean follow up from dialysis initiation of 8.8 years. Predictors of mortality were determined by univariate, multivariate analysis and survival via Kaplan-Meier analysis. Assessment of the utility of the Tangri risk calculator was carried out in addition to slope change in eGFR prior to dialysis commencement. RESULTS Baseline characteristics and the preferred mode of dialysis remained concordant with the original trial. The mortality rate at the end of the study period was 60% (56/94) with 30% (29) of patients having been transplanted. Highlighted in the 5 year data a significant proportion of mortality was made up of vascular disease and sepsis (71%) but this proportion had decreased (57%) by 10 years. Cardiac disease was the commonest cause of death but notably in 18% of patients, death was related to dialysis or withdrawal of treatment. Vascular disease and diabetes remained independent risk factors and predicative of mortality. Calcium-phosphate product which was associated in the early years with mortality was not in later years. Use of the risk calculator was predictive of commencement of RRT but not mortality but slope change in eGFR was predictive of mortality. CONCLUSIONS Although diabetes and vascular disease remained predictive of mortality, interestingly calcium-phosphate levels are no longer significant and may be a more specific predictor of early cardiac mortality. Slope eGFR changes prior to RRT are a predictor of mortality. We speculate that aggressive management of cardiac risk factors in addition to early transplantation may be key to influencing the impact of survival in this cohort in addition to possible measures to delay renal progression.

Abstract
Life expectancy after pediatric renal transplantation remains lower than that of the normal population largely due to cardiovascular morbidity and mortality. Hyperlipidemia is a potentially modifiable risk factor for cardiovascular morbidity. Retrospective chart review of all available pediatric renal transplant patients (26) in a single center with assessment of anthropometry, renal function, steroid, calcineurin or mTOR inhibitor exposure and Ω3 FA supplementation. Eighteen transplant recipients without Ω3 FA supplementation served as control. Nutrition and supplement surveys were conducted with standardized questionnaires. Fasting cholesterol values were compared using the latest value prior to start of Ω3 FA and at last follow-up. Eight patients (five receiving mTOR inhibitor) started Ω3 FA supplementation at a mean dose of 29.2 ± 12 mg of EPA/kg and 16.1 ± 7.4 mg DHA/kg body weight. Median duration of treatment was 2.5 yr (range 0.8-5.9 yr) and their total fasting cholesterol at last follow-up dropped significantly from 5.08 ± 0.97 (control group 3.77 ± 0.81, p = 0.0084) to 4.17 ± 0.54 mm (p = 0.0158). High-density lipoprotein cholesterol increased not significantly from 1.74 ± 0.49 to 2.02 ± 0.93 mm. No patient had increased bleeding. Supplementation of omega-3 FAs may reduce hyperlipidaemia after pediatric renal transplantation.

Abstract
Patients with chronic kidney disease (CKD) have a much higher risk of cardiovascular diseases than the general population. Endothelial dysfunction, which participates in accelerated atherosclerosis, is a hallmark of CKD. Patients with CKD display impaired endothelium-dependent vasodilatation, elevated soluble biomarkers of endothelial dysfunction, and increased oxidative stress. They also present an imbalance between circulating endothelial populations reflecting endothelial injury (endothelial microparticles and circulating endothelial cells) and repair (endothelial progenitor cells). Endothelial damage induced by a uremic environment suggests an involvement of uremia-specific factors. Several uremic toxins, mostly protein-bound, have been shown to have specific endothelial toxicity: ADMA, homocysteine, AGEs, and more recently, p-cresyl sulfate and indoxyl sulfate. These toxins, all poorly removed by hemodialysis therapies, share mechanisms of endothelial toxicity: they promote pro-oxidant and pro-inflammatory response and inhibit endothelial repair. This article (i) reviews the evidence for endothelial dysfunction in CKD, (ii) specifies the involvement of protein-bound uremic toxins in this dysfunction, and (iii) discusses therapeutic strategies for lowering uremic toxin concentrations or for countering the effects of uremic toxins on the endothelium.

Abstract
AIM To assess the effects of long-term multifactorial intervention on renal function and serum uric acid (SUA) levels and their association with estimated cardiovascular disease (eCVD) risk and actual CVD events. METHODS This prospective, randomized, target-driven study included 1123 subjects (45.6% men, age 45-65 years) with metabolic syndrome (MetS) but without diabetes or CVD. Patients were randomized to multifactorial treatment. Atorvastatin was titrated from 10-80 mg/day aiming at a low density lipoprotein cholesterol (LDL-C) target of <100 mg/dl (group A) or an LDL-C target of <130 mg/dl (group B). Changes in estimated glomerular filtration rate (eGFR) and SUA levels were recorded in all patients and in the subgroup with stage 3 chronic kidney disease (CKD; eGFR = 30-59 ml/min/1.73 m(2); n = 349). We used ANOVA to compare changes within the same group, unpaired Student t-test to compare results between groups at specific time points, and log-rank test to compare event free survival. RESULTS The eCVD-risk reduction was greater in group A. In the overall study population, eGFR increased by 3.5% (p < 0.001) and SUA levels fell by 5.6% (p < 0.001). In patients from group A with stage 3 CKD (group A1; n = 172), eGFR increased by 11.1% (p < 0.001) from baseline and by 7.5% (p < 0.001) in group B1 (n = 177; p < 0.001 vs. the change in group A1). The corresponding fall in SUA levels was 10.7% in group A1 (p < 0.001 vs. baseline) and 8.3% in group B1 (p < 0.001 vs. baseline and group A1). These changes were mainly attributed to atorvastatin treatment. Among the CKD stage 3 patients there were no CVD events in group A1, while 6 events occurred in group B1 (p = 0.014). CONCLUSIONS Multifactorial intervention in patients with MetS without established CVD improved renal function and reduced SUA levels. These changes were more prominent in stage 3 CKD patients and might have contributed to the reduction in eCVD risk and clinical events. Original study registration number [ClinicalTrials.gov ID: NCT00416741].
