Abstract
BACKGROUND Cardiovascular disease is the most frequent cause of death in people with early stages of chronic kidney disease (CKD), and the absolute risk of cardiovascular events is similar to people with coronary artery disease. This is an update of a review first published in 2009 and updated in 2014, which included 50 studies (45,285 participants). OBJECTIVES To evaluate the benefits and harms of statins compared with placebo, no treatment, standard care or another statin in adults with CKD not requiring dialysis. SEARCH METHODS We searched the Cochrane Kidney and Transplant Register of Studies up to 4 October 2023. Studies in the Register are identified through searches of CENTRAL, MEDLINE, EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov. An updated search will be undertaken every three months. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs that compared the effects of statins with placebo, no treatment, standard care, or other statins, on death, cardiovascular events, kidney function, toxicity, and lipid levels in adults with CKD (estimated glomerular filtration rate (eGFR) 90 to 15 mL/min/1.73 m2) were included. DATA COLLECTION AND ANALYSIS Two or more authors independently extracted data and assessed the study risk of bias. Treatment effects were expressed as mean difference (MD) for continuous outcomes and risk ratios (RR) for dichotomous benefits and harms with 95% confidence intervals (CI). The risk of bias was assessed using the Cochrane risk of bias tool, and the certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS We included 63 studies (50,725 randomised participants); of these, 53 studies (42,752 participants) compared statins with placebo or no treatment. The median duration of follow-up was 12 months (range 2 to 64.8 months), the median dosage of statin was equivalent to 20 mg/day of simvastatin, and participants had a median eGFR of 55 mL/min/1.73 m2. Ten studies (7973 participants) compared two different statin regimens. We were able to meta-analyse 43 studies (41,273 participants). Most studies had limited reporting and hence exhibited unclear risk of bias in most domains. Compared with placebo or standard of care, statins prevent major cardiovascular events (14 studies, 36,156 participants: RR 0.72, 95% CI 0.66 to 0.79; I2 = 39%; high certainty evidence), death (13 studies, 34,978 participants: RR 0.83, 95% CI 0.73 to 0.96; I² = 53%; high certainty evidence), cardiovascular death (8 studies, 19,112 participants: RR 0.77, 95% CI 0.69 to 0.87; I² = 0%; high certainty evidence) and myocardial infarction (10 studies, 9475 participants: RR 0.55, 95% CI 0.42 to 0.73; I² = 0%; moderate certainty evidence). There were too few events to determine if statins made a difference in hospitalisation due to heart failure. Statins probably make little or no difference to stroke (7 studies, 9115 participants: RR 0.64, 95% CI 0.37 to 1.08; I² = 39%; moderate certainty evidence) and kidney failure (3 studies, 6704 participants: RR 0.98, 95% CI 0.91 to 1.05; I² = 0%; moderate certainty evidence) in people with CKD not requiring dialysis. Potential harms from statins were limited by a lack of systematic reporting. Statins compared to placebo may have little or no effect on elevated liver enzymes (7 studies, 7991 participants: RR 0.76, 95% CI 0.39 to 1.50; I² = 0%; low certainty evidence), withdrawal due to adverse events (13 studies, 4219 participants: RR 1.16, 95% CI 0.84 to 1.60; I² = 37%; low certainty evidence), and cancer (2 studies, 5581 participants: RR 1.03, 95% CI 0.82 to 1.30; I² = 0%; low certainty evidence). However, few studies reported rhabdomyolysis or elevated creatinine kinase; hence, we are unable to determine the effect due to very low certainty evidence. Statins reduce the risk of death, major cardiovascular events, and myocardial infarction in people with CKD who did not have cardiovascular disease at baseline (primary prevention). There was insufficient data to determine the benefits and harms of the type of statin therapy. AUTHORS' CONCLUSIONS Statins reduce death and major cardiovascular events by about 20% and probably make no difference to stroke or kidney failure in people with CKD not requiring dialysis. However, due to limited reporting, the effect of statins on elevated creatinine kinase or rhabdomyolysis is unclear. Statins have an important role in the primary prevention of cardiovascular events and death in people who have CKD and do not require dialysis. Editorial note: This is a living systematic review. We will search for new evidence every three months and update the review when we identify relevant new evidence.

Renal Function-Dependent Associations of Statins with Outcomes of Ischemic Stroke. J Atheroscler Thromb 2021; 28:146-156.

Abstract
AIM Chronic kidney disease (CKD) is associated with unfavorable outcomes in patients with ischemic stroke. One major metabolic derangement of CKD is dyslipidemia, which can be managed by statins. This study aimed to investigate whether the association of statins with post-stroke outcomes would be affected by renal function. METHODS We evaluated the association of statin therapy at discharge with 3-month outcomes according to the estimated glomerular filtration rate (eGFR) of 50,092 patients with acute ischemic stroke from the Taiwan Stroke Registry from August 2006 to May 2016. The outcomes were mortality, functional outcome as modified Rankin Scale (mRS), and recurrent ischemic stroke at 3 months after index stroke. RESULTS Statin therapy at discharge was associated with lower risks of mortality (adjusted hazard ratio [aHR], 0.41; 95% confidence interval [CI], 0.34 to 0.50) and unfavorable functional outcomes (mRS 3-5; aHR, 0.80; 95% CI, 0.76 to 0.84) in ischemic stroke patients. After stratification by eGFR, the lower risk of mortality associated with statins was limited to patients with an eGFR above 15 mL/min/1.73 m2. Using statins at discharge was correlated with a lower risk of unfavorable functional outcomes in patients with an eGFR of 60-89 mL/min/1.73 m2. Statin therapy in patients with an eGFR of 60-89 mL/min/1.73 m2 may be associated with a higher risk of recurrent ischemic stroke compared with nonusers (aHR, 1.29; 95% CI, 1.07 to 1.57). CONCLUSIONS In patients with acute ischemic stroke, the associations of statins with mortality and functional outcomes was dependent on eGFR.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a progressive condition that leads to irreversible damage to the kidneys and is associated with an increased incidence of cardiovascular events and mortality. As novel interventions become available, estimates of economic and clinical outcomes are needed to guide payer reimbursement decisions. OBJECTIVE The aim of the present study was to systematically review published economic models that simulated long-term outcomes of kidney disease to inform cost-effectiveness evaluations of CKD treatments. METHODS The review was conducted across four databases (MEDLINE, Embase, the Cochrane library and EconLit) and health technology assessment agency websites. Relevant information on each model was extracted. Transition and mortality rates were also extracted to assess the choice of model parameterisation on disease progression by simulating patient's time with end-stage renal disease (ESRD) and time to ESRD/death. The incorporation of cardiovascular disease in a population with CKD was qualitatively assessed across identified models. RESULTS The search identified 101 models that met the criteria for inclusion. Models were classified into CKD models (n = 13), diabetes models with nephropathy (n = 48), ESRD-only models (n = 33) and cardiovascular models with CKD components (n = 7). Typically, published models utilised frameworks based on either (estimated or measured) glomerular filtration rate (GFR) or albuminuria, in line with clinical guideline recommendations for the diagnosis and monitoring of CKD. Generally, two core structures were identified, either a microsimulation model involving albuminuria or a Markov model utilising CKD stages and a linear GFR decline (although further variations on these model structures were also identified). Analysis of parameter variability in CKD disease progression suggested that mean time to ESRD/death was relatively consistent across model types (CKD models 28.2 years; diabetes models with nephropathy 24.6 years). When evaluating time with ESRD, CKD models predicted extended ESRD survival over diabetes models with nephropathy (mean time with ESRD 8.0 vs. 3.8 years). DISCUSSION This review provides an overview of how CKD is typically modelled. While common frameworks were identified, model structure varied, and no single model type was used for the modelling of patients with CKD. In addition, many of the current methods did not explicitly consider patient heterogeneity or underlying disease aetiology, except for diabetes. However, the variability of individual patients' GFR and albuminuria trajectories perhaps provides rationale for a model structure designed around the prediction of individual patients' GFR trajectories. Frameworks of future CKD models should be informed and justified based on clinical rationale and availability of data to ensure validity of model results. In addition, further clinical and observational research is warranted to provide a better understanding of prognostic factors and data sources to improve economic modelling accuracy in CKD.

Abstract
Background The 2013 American College of Cardiology/American Heart Association cholesterol guidelines recognize cardiovascular disease and diabetes mellitus but not chronic kidney disease ( CKD ) as high-risk conditions warranting statin therapy. Statin use may be lower for adults with CKD compared with adults with conditions that have guideline indications for statin use. Methods and Results We analyzed data from the National Health and Nutrition Examination Surveys from 1999-2002 through 2011-2014 to determine trends in the percentage of US adults ≥20 years of age with and without CKD taking statins. CKD was defined by an estimated glomerular filtration rate <60 mL/min per 1.73m2 or albumin-to-creatinine ratio ≥30 mg/g. Statin use was identified through a medication inventory. Between 1999-2002 and 2011-2014, the percentage of adults taking statins increased from 17.6% to 35.7% among those with CKD and from 6.8% to 14.7% among those without CKD . After multivariable adjustment, adults with CKD were not more likely to be taking statins compared with those without CKD (prevalence ratio, 1.01; 95% CI] 0.96-1.08). Among adults without a history of cardiovascular disease, those with CKD but not diabetes mellitus were less likely to be taking statins compared with those with diabetes mellitus but not CKD (prevalence ratio, 0.54; 95% CI , 0.44-0.66). Among adults with a history of cardiovascular disease, there was no difference in statin use between those with CKD but not diabetes mellitus versus those with diabetes mellitus but not CKD (prevalence ratio, 0.95; 95% CI , 0.79-1.15). Conclusions CKD does not appear to be a major stimulus for statin use among US adults.

Abstract
OBJECTIVE The aim of this study was to examine the association between BMI categories, stratified by metabolic health status, and the risk of kidney function decline (KFD). METHODS In this study, 42,128 adult patients with a stable BMI were classified over a 3-year baseline window by BMI and metabolic health status (assessed by Adult Treatment Panel-III criteria). KFD was defined as an estimated glomerular filtration rate (eGFR) decline ≥ 30%, eGFR < 15 mL/min/1.73 m2 , or receipt of dialysis and/or transplant. RESULTS Over a median of 5.1 years (interquartile range 2.1-8.9), 6,533 (15.5%) individuals developed KFD. Compared with the normal weight, metabolically healthy category, metabolically healthy obesity was associated with a higher risk of KFD (adjusted hazard ratio [aHR] 1.52; 95% CI: 1.22-1.89). aHRs for KFD were 1.17 (95% CI: 0.89-1.53), 2.21 (95% CI: 1.59-3.08), and 2.20 (95% CI: 1.55-3.11) for metabolically healthy obesity with BMI 30 to 34.9, BMI 35 to 39.9, and BMI ≥ 40 kg/m2 . These associations were consistent among men and women, patients with eGFR ≥ or < 90 mL/min/1.73 m2 , and age ≥ or < 55 years. The risk of KFD was highest among metabolically unhealthy individuals with BMI ≥ 40 (aHR 4.02; 95% CI: 3.40-4.75 vs. metabolically healthy individuals with normal weight). CONCLUSIONS Obesity, whether in the presence or absence of metabolic health, is a risk factor for KFD.

Abstract
We discuss mechanisms of increased cardiovascular disease (CVD) in patients with chronic kidney disease (CKD) and strategies for managing cardiovascular (CV) risk in these patients. Our focus was mainly on decreasing CV events and progression of microvascular complications by reducing levels of glucose and lipids. We searched PubMed with no limit on the date of the article. All articles were discussed among all authors. We chose pertinent articles, and searched their references in turn for additional relevant publications.

Abstract
Background Gestational diabetes is known as one of the diseases through pregnancy. In the present study, changes in proteinuria after atorvastatin administration among patients with history of gestational diabetes were studied. Materials and Methods In this randomized clinical trial, 42 patients were included in the study. Atorvastatin was administered for 21 patients, and 21 patients were designated as control group. Lipid profile, protein, and 24 h urine creatinine (uCr) levels were determined in the beginning and 3 months after intervention. P < 0.05 was considered statistically significant. Results Lipid profile in intervention group was enhanced; low-density lipoprotein (LDL) had decreased while triglyceride had not changed and high-density lipoprotein had been increased. There was no statistically significant change in serum Cr, serum urea, estimated glomerular filtration rate, uCr, urine volume, 24-h urine protein level, or urine protein/Cr ratio on both groups during the study; also, there was no statistically significant difference between groups. Conclusions Although LDL level decreased after atorvastatin therapy, atorvastatin therapy had no effect on the level of proteinuria or other parameters related to kidney function.

Abstract
Chronic kidney disease (CKD) is associated with an enhanced oxidative stress and deep modifications in lipid and lipoprotein metabolism. First, many oxidized lipids accumulate in CKD and were shown to exert toxic effects on cells and tissues. These lipids are known to interfere with many cell functions and to be pro-apoptotic and pro-inflammatory, especially in the cardiovascular system. Some, like F2-isoprostanes, are directly correlated with CKD progression. Their accumulation, added to their noxious effects, rendered their nomination as uremic toxins credible. Similarly, lipoproteins are deeply altered by CKD modifications, either in their metabolism or composition. These impairments lead to impaired effects of HDL on their normal effectors and may strongly participate in accelerated atherosclerosis and failure of statins in end-stage renal disease patients. This review describes the impact of oxidized lipids and other modifications in the natural history of CKD and its complications. Moreover, this review focuses on the modifications of lipoproteins and their impact on the emergence of cardiovascular diseases in CKD as well as the appropriateness of considering them as actual mediators of uremic toxicity.

Liu JC, Hsu YP, Wu SY. Statins and Renin Angiotensin System Inhibitors Dose-Dependently Protect Hypertensive Patients against Dialysis Risk. PLoS One 2016; 11:e0162588. [PMID: 27632175 PMCID: PMC5025231 DOI: 10.1371/journal.pone.0162588] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2016] [Accepted: 08/25/2016] [Indexed: 12/20/2022] Open
Abstract
Background Taiwan has the highest renal disease incidence and prevalence in the world. We evaluated the association of statin and renin–angiotensin system inhibitor (RASI) use with dialysis risk in hypertensive patients. Methods Of 248,797 patients who received a hypertension diagnosis in Taiwan during 2001–2012, our cohort contained 110,829 hypertensive patients: 44,764 who used RASIs alone; 7,606 who used statins alone; 27,836 who used both RASIs and statins; and 33,716 who used neither RASIs or statins. We adjusted for the following factors to reduce selection bias by using propensity scores (PSs): age; sex; comorbidities; urbanization level; monthly income; and use of nonstatin lipid-lowering drugs, metformin, aspirin, antihypertensives, diuretics, and beta and calcium channel blockers. The statin and RASI use index dates were considered the hypertension confirmation dates. To examine the dose–response relationship, we categorized only statin or RASI use into four groups in each cohort: <28 (nonusers), 28–90, 91–365, and >365 cumulative defined daily doses (cDDDs). Results In the main model, PS-adjusted hazard ratios (aHRs; 95% confidence intervals [CIs]) for dialysis risk were 0.57 (0.50–0.65), 0.72 (0.53–0.98), and 0.47 (0.41–0.54) in the only RASI, only statin, and RASI + statin users, respectively. RASIs dose-dependently reduced dialysis risk in most subgroups and in the main model. RASI use significantly reduced dialysis risk in most subgroups, regardless of comorbidities or other drug use (P < 0.001). Statins at >365 cDDDs protected hypertensive patients against dialysis risk in the main model (aHR = 0.62, 95% CI: 0.54–0.71), regardless of whether a high cDDD of RASIs, metformin, or aspirin was used. Conclusion Statins and RASIs independently have a significant dose-dependent protective effect against dialysis risk in hypertensive patients. The combination of statins and RASIs can additively protect hypertensive patients against dialysis risk.

Eligibility for Statin Treatment in Korean Subjects with Reduced Renal Function: An Observational Study. Endocrinol Metab (Seoul) 2016; 31:402-409. [PMID: 27586450 PMCID: PMC5053052 DOI: 10.3803/enm.2016.31.3.402] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2016] [Revised: 06/26/2016] [Accepted: 06/30/2016] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND The purpose of this study was to investigate the relationship between statin eligibility and the degree of renal dysfunction using the Adult Treatment Panel (ATP) III and the American College of Cardiology (ACC)/American Heart Association (AHA) guidelines in Korean adults. METHODS Renal function was assessed in 18,746 participants of the Kangbuk Samsung Health Study from January 2011 to December 2012. Subjects were divided into three groups according to estimated glomerular filtration rate (eGFR): stage 1, eGFR ≥90 mL/min/1.73 m²; stage 2, eGFR 60 to 89 mL/min/1.73 m²; and stages 3 to 5, eGFR <60 mL/min/1.73 m². Statin eligibility in these groups was determined using the ATP III and ACC/AHA guidelines, and the risk for 10-year atherosclerotic cardiovascular disease (ASCVD) was calculated using the Framingham Risk Score (FRS) and Pooled Cohort Equation (PCE). RESULTS There were 3,546 (18.9%) and 4,048 (21.5%) statin-eligible subjects according to ATP III and ACC/AHA guidelines, respectively. The proportion of statin-eligible subjects increased as renal function deteriorated. Statin eligibility by the ACC/AHA guidelines showed better agreement with the Kidney Disease Improving Global Outcomes (KDIGO) recommendations compared to the ATP III guidelines in subjects with stage 3 to 5 chronic kidney disease (CKD) (κ value, 0.689 vs. 0.531). When the 10-year ASCVD risk was assessed using the FRS and PCE, the mean risk calculated by both equations significantly increased as renal function declined. CONCLUSIONS The proportion of statin-eligible subjects significantly increased according to worsening renal function in this Korean cohort. ACC/AHA guideline showed better agreement for statin eligibility with that recommended by KDIGO guideline compared to ATP III in subjects with CKD.

Meta-Analyses of Statin Therapy for Primary Prevention Do Not Answer Key Questions: An Empirical Appraisal of 5 Years of Statin Meta-Analyses. Am J Cardiovasc Drugs 2015; 15:379-86.

Abstract
Although meta-analyses of statins in primary prevention are designed to provide doctors and patients with better evidence about the risks and potential benefits of treatment, they may ignore important patient-centered outcomes and concerns. We examined all meta-analyses of statins for primary prevention over the last 5 years. We assessed whether each meta-analysis addressed five key points: whether authors examined endpoints based on the use of statin therapy, and not stratified by low-density lipoprotein reduction; whether authors included only studies of statin versus placebo, and not varying doses or brands of statin; whether authors considered commonly cited harms; whether secondary prevention patients were excluded; and, whether overall mortality was examined. We examined 189 articles to identify 24 meta-analyses of statins that made claims regarding primary prevention. Six studies (25%) reported outcomes as a function of reduction in serum lipid levels rather than treatment received. Seven studies (29%) included trials of high-dose versus low-dose statin in their analysis. Five studies (21%) did not examine all-cause mortality. The majority of studies (n = 21, 88%) failed to exclude patients with known cardiovascular disease, and 22 (92%) studies failed to assess two of three common safety concerns. Nevertheless, most (n = 20, 83%) meta-analyses supported the use of statins in primary prevention. Based on our findings, we conclude that most recent meta-analyses of statins for primary prevention do not adequately address the question they seek to answer.

Abstract
Lipids are essential components of cell membranes, contributing to cell fuel, myelin formation, subcellular organelle function, and steroid hormone synthesis. Children with chronic kidney disease (CKD) and end-stage renal disease (ESRD) exhibit various co-morbidities, including dyslipidemia. The prevalence of dyslipidemias in children with CKD and ESRD is high, being present in 39-65% of patients. Elevated lipid levels in children without renal disease are a risk factor for cardiovascular disease (CVD), while the risk for CVD in pediatric CKD/ESRD is unclear. The pathogenesis of dyslipidemia in CKD features various factors, including increased levels of triglycerides, triglyceride-rich lipoproteins, apolipoprotein C3 (ApoC-III), decreased levels of cholesterylester transfer protein and high-density lipoproteins, and aberrations in serum very low-density and intermediate-density lipoproteins. If initial risk assessment indicates that a child with advanced CKD has 2 or more co-morbidities for CVD, first-line treatment should consist of non-pharmacologic management such as therapeutic lifestyle changes and dietary counseling. Pharmacologic treatment of dyslipidemia may reduce the incidence of CVD in children with CKD/ESRD, but randomized trials are lacking. Statins are the only class of lipid-lowering drugs currently approved by the U.S. Food and Drug Administration (FDA) for use in the pediatric population. FDA-approved pediatric labeling for these drugs is based on results from placebo-controlled trial results, showing 30-50% reductions in baseline low-density lipoprotein cholesterol. Although statins are generally well tolerated in adults, a spectrum of adverse events has been reported with their use in both the clinical trial and post-marketing settings.

Abstract
BACKGROUND AND OBJECTIVES This study aimed to determine absolute and excess stroke risks in people with ESRD compared with the general population. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This cohort study used data linkage between the Australia and New Zealand Dialysis and Transplant Registry and hospital and death records for 10,745 people with ESRD in New South Wales from 2000 to 2010. For the general population, Australian Institute of Health and Welfare hospital usage records and Australian Bureau of Statistics census data were used. Rates and standardized incidence rate ratios of hospitalization with a stroke were calculated. RESULTS People with ESRD had 640 hospitalizations with stroke in 49,472 person-years of follow-up (1294 per 100,000 person-years), and people in the general population had 338,392 hospitalizations with stroke (212 per 100,000 person-years), an incidence rate ratio of 3.32 (95% confidence interval, 3.31 to 3.33). Excess risk was greater for women (incidence rate ratio, 5.14; 95% confidence interval, 5.11 to 5.18) than men (incidence rate ratio, 2.52; 95% confidence interval, 2.51 to 2.54; P for interaction <0.001) and decreased with age. People ages 35-39 years old with ESRD had an 11 times increased risk of stroke (incidence rate ratio, 11.08; 95% confidence interval, 9.41 to 13.05), and risk in people ages ≥85 years old increased 2-fold (incidence rate ratio, 2.04; 95% confidence interval, 1.87 to 2.23; P for interaction <0.001). Excess risk was greater for intracerebral hemorrhage (incidence rate ratio, 4.18; 95% confidence interval, 4.11 to 4.26) than ischemic stroke (incidence rate ratio, 3.43; 95% confidence interval, 3.40 to 3.45; P for interaction <0.01). CONCLUSIONS People with ESRD have a substantially higher risk of stroke, particularly women and young people, and hemorrhagic stroke. Future work could investigate effective and safe interventions for primary and secondary prevention of stroke in people with ESRD.

Abstract
The diagnosis of renal artery stenosis (RAS) has become increasingly common in part due to greater awareness of ischemic renal disease and increased use of diagnostic techniques. Over 90 % of RAS cases are caused by atherosclerotic renovascular disease (ARVD). Patients with ARVD are at high risk for fatal and nonfatal cardiovascular and renal events. The mortality rate in patients with ARVD is high, especially with other cardiovascular or renal comorbidities. Recent clinical studies have provided substantial evidence concerning medical therapy and endovascular interventional therapeutic approaches for ARVD. Despite previous randomized clinical trials, the optimal therapy for ARVD remained uncertain until the results of the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) trial were released recently. CORAL demonstrated that optimal medical therapy was equally effective to endovascular therapy in the treatment of ARVD. Clinicians can now practice with more evidence-based medicine to treat ARVD and potentially decrease mortality in patients with ARVD using optimal medical therapy.

Abstract
OBJECTIVE To evaluate the efficacy and safety of high-intensity statin therapy in patients with chronic kidney disease (CKD). DESIGN A systematic review and meta-analysis. DATA SOURCES Randomised controlled trials (RCTs) comparing high-intensity statin therapy (atorvastatin 80 mg or rosuvastatin 20/40 mg) with moderate/mild statin treatment or placebo were derived from the databases (PubMed, Embase, Ovid, the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, and ISI Web of Knowledge). OUTCOME MEASURE Primary end points: clinical events (all-cause mortality, stroke, myocardial infarction and heart failure); secondary end points: serum lipid, renal function changes and adverse events. RESULTS A total of six RCTs with 10,993 adult patients with CKD were included. A significant decrease in stroke was observed in the high-intensity statin therapy group (RR 0.69, 95% CI 0.56 to 0.85). However, the roles of high-intensity statin in decreasing all-cause mortality (RR 0.85, 95% CI 0.67 to 1.09), myocardial infarction (RR 0.69, 95% CI 0.40 to 1.18) and heart failure (RR 0.73, 95% CI 0.48 to 1.13) remain unclear with low evidence. High-intensity statin also had obvious effects on lowering the LDL-C level but no clear effects on renal protection. Although pooled results showed no significant difference between the intervention and control groups in adverse event occurrences, it was still insufficient to put off the doubts that high-intensity statin might increase adverse events because of limited data sources and low quality evidences. CONCLUSIONS High-intensity statin therapy could effectively reduce the risk of stroke in patients with CKD. However, its effects on all-cause mortality, myocardial infarction, heart failure and renal protection remain unclear. Moreover, it is hard to draw conclusions on the safety assessment of intensive statin treatment in this particular population. More studies are needed to credibly evaluate the effects of high-intensity statin therapy in patients with CKD.

Abstract
PURPOSE The aim of this article was to present the most important matters associated with dyslipidemia treatment in CKD patients. Moreover, the most important recommendations of the current (2013) KDIGO clinical practice guideline for lipid management in chronic kidney disease are presented. METHODS Authors looked through the most recent large clinical trials and meta-analyses and presented their results. We searched using the electronic databases [MEDLINE, EMBASE, Scopus, DARE]. Additionally, abstracts from national and international cardiovascular meetings were studied. RESULTS Analysis results suggest that statins exert beneficial effects on kidney since they considerably reduce 24 h urinary protein excretion and are associated with a rise in GFR. Beneficial effects of statins may be influenced by kidney disease stage, doses of medicine and treatment duration. Data suggest that statins are effective and safe for secondary prevention of CV events in individuals with mild CKD. Patients treated with statins had decreased frequency of major atherosclerotic events compared with placebo, reduced risk of CV mortality and deaths from all causes. CONCLUSIONS Meta-analyses results suggest that statins are associated with lipid lowering, cardiovascular and anti-proteinuric benefits in CKD patients. However, their effects on overall and cardiovascular mortality are much less obvious. Bearing in mind the advantageous effects and low risk of adverse effects, it seems that mild renal impairment should not exclude these patients from receiving a statin. However, because CKD patients in stages III-V are underrepresented in clinical trials, administration of statins to these patients who have not yet had a vascular event remains controversial.

Abstract
Background Little is known about the effect of low-density lipoprotein (LDL) cholesterol, triglyceride (TG), and high-density lipoprotein (HDL) cholesterol levels on renal function decline in patients receiving specialized pre-dialysis care. Methods In the prospective PREPARE-2 study, incident patients starting pre-dialysis care were included when referred to one of the 25 participating Dutch specialized pre-dialysis outpatient clinics (2004-2011). Clinical and laboratory data were collected every 6 months. A linear mixed model was used to compare renal function decline between patients with LDL cholesterol, TG, or HDL cholesterol levels above and below the target goals (LDL cholesterol: <2.50 mmol/l, TG: <2.25 mmol/l, and HDL cholesterol: ≥1.00 mmol/l). Additionally the HDL/LDL cholesterol ratio was investigated (≥0.4). Results In our study population (n = 306), the median age was 69 years and 70% were male. Patients with LDL cholesterol levels above the target of 2.50 mmol/l experienced an accelerated renal function decline compared to patients with levels below the target (crude additional decline: 0.10 ml/min/1.73 m2/month, 95% CI 0.00-0.20; p < 0.05). A similar trend was found for TG levels above the target of 2.25 mmol/l (0.05 ml/min/1.73 m2/month, 95% CI −0.06 to 0.16) and for a HDL/LDL cholesterol ratio below 0.4 (0.06 ml/min/1.73 m2/month, 95% CI −0.05 to 0.18). Adjustment for potential confounders resulted in similar results, and the exclusion of patients who were prescribed lipid-lowering medication (statin, fibrate, or cholesterol absorption inhibitor) resulted in a slightly larger estimated effect. Conclusion High levels of LDL cholesterol were associated with an accelerated renal function decline, independent of the prescription of lipid-lowering medication.

Abstract
The incidence and prevalence of diabetes mellitus (DM) continue to grow markedly throughout the world, due primarily to the increase in type 2 DM (T2DM). Although improvements in DM and hypertension management have reduced the proportion of diabetic individuals who develop chronic kidney disease (CKD) and progress to end-stage renal disease (ESRD), the sheer increase in people developing DM will have a major impact on dialysis and transplant needs. This KDIGO conference addressed a number of controversial areas in the management of DM patients with CKD, including aspects of screening for CKD with measurements of albuminuria and estimated glomerular filtration rate (eGFR); defining treatment outcomes; glycemic management in both those developing CKD and those with ESRD; hypertension goals and management, including blockers of the renin-angiotensin-aldosterone system; and lipid management.

Abstract
Ethnic/racial and socioeconomic status disparities in the health-care and clinical outcomes of patients with chronic kidney disease (CKD) are pervasive. The vast majority of care to decrease incidence of CKD risk and progression occurs in primary care settings. High-quality primary care, therefore, represents a key strategy through which disparities in the incidence and progression of CKD may be eliminated. The Chronic Care Model provides a framework for the delivery of high-quality primary care for chronic diseases, and it is frequently used to guide health-care quality improvement initiatives. Evidence suggests that Chronic Care Model constructs, including provider and organizational quality improvement initiatives focused on team approaches to chronic care (eg, case management, community health workers), are effective in modifying patients' CKD risks among ethnic minority and low-income patients. Other Chronic Care Model constructs, including clinical information systems (eg, disease registries), decision support interventions, and the provision of patient-centered care have been shown to improve processes related to CKD care but with limited and/or mixed effects on patient outcomes. Few studies have examined the effect of these approaches on reducing disparities. Research is needed to examine the effectiveness of these strategies to eliminate CKD disparities among vulnerable populations.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a worldwide public health problem which is at high increased risk of cardiovascular disease (CVD) and renal failure. Deterioration of kidney function causes an increase in circulating toxins, which, in turn promotes the progression of CKD. Oral adsorbents with capacity to adsorb and remove substances including uraemic toxins from the intestine could be effective in minimising kidney injury. OBJECTIVES To investigate the benefits and harms of oral adsorbents for preventing or delaying the progression of CKD. SEARCH METHODS We searched the Cochrane Renal Group's Specialised Register (to 22 September 2014) through contact with the Trials' Search Co-ordinator using search terms relevant to this review. The following four Chinese medical databases were also searched: China Biological Medicine Database (1979 to May 2012); Chinese Science and Technique Journals Database (to May 2012); China National Infrastructure (to May 2012); Wan Fang database (to May 2012). SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs comparing any oral adsorbents for preventing or delaying the progression of CKD. DATA COLLECTION AND ANALYSIS Two authors independently assessed and extracted information. Information was collected on methods, participants, interventions and outcomes (incidence of end-stage kidney disease (ESKD), mortality, quality of life and adverse events). Results were expressed as risk ratios (RR) for dichotomous outcomes or as mean differences (MD) for continuous data with 95% confidence intervals (CI). Adverse events were expressed as risk differences (RD). MAIN RESULTS Fifteen studies (1590 patients) conducted in Japan, China, and the USA were identified. The risk of bias of the included studies was moderate or high and the sample sizes were small.Three studies compared oral AST-120 plus routine treatment with placebo plus routine treatment; however data on our outcome measures of interest were not reported in two studies. These studies did not assess or did not provide data for our primary outcomes of interest (incidence of ESKD; time to ESKD; all-cause mortality). There was no significant difference in the changes of serum creatinine (SCr), slope of 1/SCr over time and creatinine clearance (CrCl) between AST-120 and placebo for patients with CKD.Eight studies compared oral AST-120 plus routine treatment with routine treatment alone; data on our outcome measures of interest were not reported in one study. There was no significant difference in incidence of ESKD, all-cause mortality and the change in health-related quality of life between AST-120 and routine treatment for patients with CKD. AST-120 showed beneficial effects on delaying the decline of kidney function measured by using the slope of change in estimated CrCl (SMD 0.39, 95% CI 0.21 to 0.5) and the mean changes of glomerular filtration rate (GFR) (MD -0.76 mL/min/mo, 95% CI -0.82 to -0.70) for patients with CKD; AST-120 was not superior to routine treatment in retarding the decline of kidney function measured by using the 1/SCr slope over time, occurrence of increase in SCr concentration, doubling of SCr concentration, changes in GFR from baseline (mL/min/1.73 m²) and slope of the eGFR curve (mL/min/mo) for patients with CKD.Three studies compared oral Ai Xi Te plus routine treatment with routine treatment alone. These studies did not assess our primary outcomes of interest. Compared with routine treatment, Ai Xi Te had positive effects on reducing SCr (MD -113.40 (µmol/L), 95% CI -188.69 to -38.10) and retarding the decline of CrCl (MD 9.74 (mL/min), 95% CI 4.28 to 15.21) for patients with CKD.One study compared oral Niaoduqing granules plus routine treatment with routine treatment alone, but did not assess our primary outcomes of interest. Compared with routine treatment, Niaoduqing granules had positive effects on reducing SCr (MD -135.60 (µmol/L), 95% CI -198.03 to -73.17) and CrCl (MD 13.30 (mL/min), 95% CI 5.69 to 20.91).The most commonly reported adverse events associated with AST-120 and Ai Xi Te were gastrointestinal symptoms however no serious adverse events were reported. AUTHORS' CONCLUSIONS Few studies reported our primary outcomes of interest. For our secondary outcomes, there is evidence of limited quality that AST-120, Ai Xi Te and Niaoduqing granules may have positive effects on delaying the decline of kidney function. There were no serious adverse events for any of the interventions in patients with CKD. Given the lack of information for our primary outcomes, the low methodological quality of most studies, and the small sample sizes, there is no strong evidence on the effectiveness of these oral adsorbents.

Abstract
BACKGROUND Cardiovascular disease (CVD) is the most frequent cause of death in people with early stages of chronic kidney disease (CKD), for whom the absolute risk of cardiovascular events is similar to people who have existing coronary artery disease. This is an update of a review published in 2009, and includes evidence from 27 new studies (25,068 participants) in addition to the 26 studies (20,324 participants) assessed previously; and excludes three previously included studies (107 participants). This updated review includes 50 studies (45,285 participants); of these 38 (37,274 participants) were meta-analysed. OBJECTIVES To evaluate the benefits (such as reductions in all-cause and cardiovascular mortality, major cardiovascular events, MI and stroke; and slow progression of CKD to end-stage kidney disease (ESKD)) and harms (muscle and liver dysfunction, withdrawal, and cancer) of statins compared with placebo, no treatment, standard care or another statin in adults with CKD who were not on dialysis. SEARCH METHODS We searched the Cochrane Renal Group's Specialised Register to 5 June 2012 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs that compared the effects of statins with placebo, no treatment, standard care, or other statins, on mortality, cardiovascular events, kidney function, toxicity, and lipid levels in adults with CKD not on dialysis were the focus of our literature searches. DATA COLLECTION AND ANALYSIS Two or more authors independently extracted data and assessed study risk of bias. Treatment effects were expressed as mean difference (MD) for continuous outcomes (lipids, creatinine clearance and proteinuria) and risk ratio (RR) for dichotomous outcomes (major cardiovascular events, all-cause mortality, cardiovascular mortality, fatal or non-fatal myocardial infarction (MI), fatal or non-fatal stroke, ESKD, elevated liver enzymes, rhabdomyolysis, cancer and withdrawal rates) with 95% confidence intervals (CI). MAIN RESULTS We included 50 studies (45,285 participants): 47 studies (39,820 participants) compared statins with placebo or no treatment and three studies (5547 participants) compared two different statin regimens in adults with CKD who were not yet on dialysis. We were able to meta-analyse 38 studies (37,274 participants).The risk of bias in the included studies was high. Seven studies comparing statins with placebo or no treatment had lower risk of bias overall; and were conducted according to published protocols, outcomes were adjudicated by a committee, specified outcomes were reported, and analyses were conducted using intention-to-treat methods. In placebo or no treatment controlled studies, adverse events were reported in 32 studies (68%) and systematically evaluated in 16 studies (34%).Compared with placebo, statin therapy consistently prevented major cardiovascular events (13 studies, 36,033 participants; RR 0.72, 95% CI 0.66 to 0.79), all-cause mortality (10 studies, 28,276 participants; RR 0.79, 95% CI 0.69 to 0.91), cardiovascular death (7 studies, 19,059 participants; RR 0.77, 95% CI 0.69 to 0.87) and MI (8 studies, 9018 participants; RR 0.55, 95% CI 0.42 to 0.72). Statins had uncertain effects on stroke (5 studies, 8658 participants; RR 0.62, 95% CI 0.35 to 1.12).Potential harms from statin therapy were limited by lack of systematic reporting and were uncertain in analyses that had few events: elevated creatine kinase (7 studies, 4514 participants; RR 0.84, 95% CI 0.20 to 3.48), liver function abnormalities (7 studies, RR 0.76, 95% CI 0.39 to 1.50), withdrawal due to adverse events (13 studies, 4219 participants; RR 1.16, 95% CI 0.84 to 1.60), and cancer (2 studies, 5581 participants; RR 1.03, 95% CI 0.82 to 130).Statins had uncertain effects on progression of CKD. Data for relative effects of intensive cholesterol lowering in people with early stages of kidney disease were sparse. Statins clearly reduced risks of death, major cardiovascular events, and MI in people with CKD who did not have CVD at baseline (primary prevention). AUTHORS' CONCLUSIONS Statins consistently lower death and major cardiovascular events by 20% in people with CKD not requiring dialysis. Statin-related effects on stroke and kidney function were found to be uncertain and adverse effects of treatment are incompletely understood. Statins have an important role in primary prevention of cardiovascular events and mortality in people who have CKD.

Abstract
BACKGROUND AND OBJECTIVES Hyperlipidemia is common in patients with CKD. The objective of this study was to evaluate whether measures of plasma lipids and lipoproteins predict progression of kidney disease in patients with CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Prospective cohort study in adults (n=3939) with CKD aged 21-74 years recruited between 2003 and 2008 and followed for a median of 4.1 years. At baseline, total cholesterol, triglycerides, very-low-density lipoprotein cholesterol (VLDL-C), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), apoA-I , apoB, and lipoprotein(a) [Lp(a)] were measured. The outcomes were composite end point of ESRD or 50% decline in eGFR from baseline (rate of change of GFR). RESULTS Mean age of the study population was 58.2 years, and the mean GFR was 44.9 ml/min per 1.73 m(2); 48% of patients had diabetes. None of the lipid or lipoprotein measures was independently associated with risk of the composite end point or rate of change in GFR. However, there were significant (P=0.01) interactions by level of proteinuria. In participants with proteinuria<0.2 g/d, 1-SD higher LDL-C was associated with a 26% lower risk of the renal end point (hazard ratio [HR], 0.74; 95% confidence interval [95% CI], 0.59 to 0.92; P=0.01), and 1-SD higher total cholesterol was associated with a 23% lower risk of the renal end point (HR, 0.77; 95% CI, 0.62 to 0.96; P=0.02). In participants with proteinuria>0.2 g/d, neither LDL-C (HR, 0.98; 95% CI, 0.98 to 1.05) nor total cholesterol levels were associated with renal outcomes. Treatment with statins was reported in 55% of patients and was differential across lipid categories. CONCLUSIONS In this large cohort of patients with CKD, total cholesterol, triglycerides, VLDL-C, LDL-C, HDL-C, apoA-I, apoB, and Lp(a) were not independently associated with progression of kidney disease. There was an inverse relationship between LDL-C and total cholesterol levels and kidney disease outcomes in patients with low levels of proteinuria.

Abstract
It is well known that statins exert their main effect by inhibiting cholesterol synthesis through the inhibition of the 3-hydroxy-3-methyl-glutaryl-CoA reductase enzyme. The pleiotropic effects of statins, which are independent of their inhibition of cholesterol synthesis, have explained many of the beneficial effects of these drugs in a variety of disorders such as malignancies, infection, and sepsis, as well as in cardiovascular and rheumatologic disorders. However, the role of these drugs in renal disorders remains controversial. In the present review, we examine the most recent findings involving statins and renal disease among different clinical scenarios, including chronic kidney disease, contrast-induced nephropathy, renal injury after coronary artery bypass surgery, and renal transplant patients.

Abstract
BACKGROUND Patients with chronic kidney disease (CKD) is a very high risk cardiovascular disease population and should be treated aggressively. We investigated lipid management in CKD patients with atherosclerosis in Taiwan. METHODS 3057 patients were enrolled in a multi-center study (T-SPARCLE). Lipid goal are defined as total cholesterol (TC) < 160mg/dl, low-density lipoprotein (LDL) <100 mg/dl, high-density lipoprotein (HDL) > 40 mg/dl in men, HDL > 50 mg/dl in women, non-HDL cholesterol < 130mg/dl, and triglyceride < 150 mg/dl. RESULTS Compared with those without CKD (n=2239), patients with CKD (n=818) had more co-morbidities (hypertension, glucose intolerance, stroke and heart failure) and lower HDL but higher triglyceride levels. Overall 2168 (70.5%) patients received lipid-lowering agents. There was similar equivalent statin potency between CKD and non-CKD groups. The goal attainment is lower in HDL and TG in the CKD group as compared with non-CKD subjects (47.1 vs. 51.9% and 63.2 vs. 68.9% respectively, both p < 0.02). Analysis of sex and CKD interaction on goals attainment showed female CKD subjects had lower non-HDL and TG goals attainment compared with non-CKD males (both p < 0.019). CONCLUSION Although presenting with more comorbidities, the CKD population had suboptimal lipid goal attainment rate as compared with the non-CKD population. Further efforts may be required for better lipid control especially on the female CKD subjects.

Abstract
BACKGROUND Statins are commonly used to lower total cholesterol levels in the general population to prevent cardiovascular events. However, the effects of statins in patients with chronic kidney disease remain unclear. We therefore performed a meta-analysis to assess the effects of statin therapy on cardiovascular outcomes in patients with mild to moderate chronic kidney disease. METHODS We systematically searched PubMed, EmBase, the Cochrane Central Register of Controlled Trials, proceedings of major meetings, and reference lists of articles for relevant literature. Only randomized clinical trials were included. Outcomes analysed included cardiovascular disease, total mortality, myocardial infarction, stroke, cardiovascular death, and possible drug-related adverse events. Subgroup analyses were also performed based on the population characteristics and clinical indexes. RESULTS Twelve trials met our inclusion criteria. Overall, statin therapy resulted in a 24% reduction in the risk of cardiovascular disease (RR = 0.76,95% confidence interval [CI], 0.72- 0.80), a 21% reduction in the risk of total mortality (RR = 0.79,95% CI, 0.72-0.86), a 34% reduction in the risk of myocardial infarction (RR = 0.66,95% CI, 0.52-0.83), a 30% reduction in the risk of stroke (RR = 0.70,95% CI, 0.57-0.85), and a 17% reduction in the risk of cardiovascular mortality (RR = 0.83,95% CI, 0.73- 0.93). No statistically significant drug-related adverse events were noted. Subgroup analysis indicated that some important factors such as baseline creatinine level ≥1.5 mg/dL, baseline glomerular filtration rate (GFR), and cardiovascular disease history could affect cardiovascular outcomes. CONCLUSION Statin therapy had a clear effect on cardiovascular disease, total mortality, stroke, and myocardial infarction in patients with mild to moderate renal disease. Subgroup analysis indicated that baseline GFR, baseline creatinine level, and a history of cardiovascular disease might play an important role in the cardiovascular outcomes.

Abstract
BACKGROUND People with chronic kidney disease (CKD) have higher risks of cardiovascular disease compared to the general population. Specifically, cardiovascular deaths account most deaths in kidney transplant recipients. Statins are a potentially beneficial intervention for kidney transplant patients given their established benefits in patients at risk of cardiovascular disease in the general population. This is an update of a review first published in 2009. OBJECTIVES We aimed to evaluate the benefits (reductions in all-cause and cardiovascular mortality, major cardiovascular events, myocardial infarction and stroke, and progression of CKD to requiring dialysis) and harms (muscle or liver dysfunction, withdrawal, cancer) of statins compared to placebo, no treatment, standard care, or another statin in adults with CKD who have a functioning kidney transplant. SEARCH METHODS We searched the Cochrane Renal Group's Specialised Register to 29 February 2012 through contact with the Trials Search Co-ordinator using search terms relevant to this review. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs that compared the effects of statins with placebo, no treatment, standard care, or statins on mortality, cardiovascular events, kidney function and toxicity in kidney transplant recipients. DATA COLLECTION AND ANALYSIS Two authors independently extracted data and assessed risk of bias. Treatment effects were expressed as mean difference (MD) for continuous outcomes (lipids, glomerular filtration rate (GFR), proteinuria) and relative risk (RR) for dichotomous outcomes (major cardiovascular events, mortality, fatal or non-fatal myocardial infarction, fatal or non-fatal stroke, elevated muscle or liver enzymes, withdrawal due to adverse events, cancer, end-stage kidney disease (ESKD), acute allograft rejection) together with 95% confidence intervals (CI). MAIN RESULTS We identified 22 studies (3465 participants); 17 studies (3282 participants) compared statin with placebo or no treatment, and five studies (183 participants) compared two different statin regimens.From data generally derived from a single high-quality study, it was found that statins may reduce major cardiovascular events (1 study, 2102 participants: RR 0.84, CI 0.66 to 1.06), cardiovascular mortality (4 studies, 2322 participants: RR 0.68, CI 0.45 to 1.01), and fatal or non-fatal myocardial infarction (1 study, 2102 participants: RR 0.70, CI 0.48 to 1.01); although effect estimates lack precision and include the possibility of no effect.Statins had uncertain effects on all-cause mortality (6 studies, 2760 participants: RR 1.08, CI 0.63 to 1.83); fatal or non-fatal stroke (1 study, 2102 participants: RR 1.18, CI 0.85 to 1.63); creatine kinase elevation (3 studies, 2233 participants: RR 0.86, CI 0.39 to 1.89); liver enzyme elevation (4 studies, 608 participants: RR 0.62, CI 0.33 to 1.19); withdrawal due to adverse events (9 studies, 2810 participants: RR 0.89, CI 0.74 to 1.06); and cancer (1 study, 2094 participants: RR 0.94, CI 0.82 to 1.07).Statins significantly reduced serum total cholesterol (12 studies, 3070 participants: MD -42.43 mg/dL, CI -51.22 to -33.65); low-density lipoprotein cholesterol (11 studies, 3004 participants: MD -43.19 mg/dL, CI -52.59 to -33.78); serum triglycerides (11 studies, 3012 participants: MD -27.28 mg/dL, CI -34.29 to -20.27); and lowered high-density lipoprotein cholesterol (11 studies, 3005 participants: MD -5.69 mg/dL, CI -10.35 to -1.03).Statins had uncertain effects on kidney function: ESKD (6 studies, 2740 participants: RR 1.14, CI 0.94 to 1.37); proteinuria (2 studies, 136 participants: MD -0.04 g/24 h, CI -0.17 to 0.25); acute allograft rejection (4 studies, 582 participants: RR 0.88, CI 0.61 to 1.28); and GFR (1 study, 62 participants: MD -1.00 mL/min, CI -9.96 to 7.96).Due to heterogeneity in comparisons, data directly comparing differing statin regimens could not be meta-analysed. Evidence for statins in people who have had a kidney transplant were sparse and lower quality due to imprecise effect estimates and provided limited systematic evaluation of treatment harm. AUTHORS' CONCLUSIONS Statins may reduce cardiovascular events in kidney transplant recipients, although treatment effects are imprecise. Statin treatment has uncertain effects on overall mortality, stroke, kidney function, and toxicity outcomes in kidney transplant recipients. Additional studies would improve our confidence in the treatment benefits and harms of statins on cardiovascular events in this clinical setting.

Abstract
Introduction: Chronic kidney disease (CKD) is a major public health problem where majority of patients are managed in the primary care. The major risk factors are advanced age, hypertension and diabetes mellitus, and risk factors control is paramount to prevent progression to CKD. The objective of the study is to describe the epidemiology and quality of care of patients with CKD stages 3 to 5 at National Healthcare Group Polyclinics (NHGP). Materials and Methods: The study was carried out using data from National Healthcare Group (NHG) Renal Registry. Patients were included if they were identified to have CKD based on ICD-9-CM codes and laboratory results. Results: Overall, the number of CKD patients increased more than 2 fold from 4734 in 2007 to 10,245 in 2011. In 2011, the majority belonged to stages 3A (39.6%) and 3B (37.6%), had hypertension (98.2%), dyslipidemia (97.2%) and diabetes mellitus (68.7%). From 2007 to 2011, among those with hypertension, the use of angiotensin converting enzyme (ACE) inhibitors and/or angiotensin receptor blockers increased from 78.4% to 84.1%, and the percentage with good systolic blood pressure control (<130 mmHg) improved from 18.7% to 36.3%. Among those with dyslipidemia, the use of statins increased from 81% to 87.1%, and the percentage of patients with low density lipoproteins (LDL) <2.6 mmol/L increased from 40% to 54.7%. However, among those with diabetes mellitus, mean glycated haemoglobin (HBA1c) increased from 7.4% to 7.6%, and the percentage of patients with HBA1c ≤7.0% decreased from 44.5% to 39.4%. Conclusion: The number of CKD patients in NHGP has increased significantly from 2007 to 2011 at an average annual rate of 21.3%. Majority of patients the study conducted in 2011 were in stage 3A and stage 3B. Blood pressure and LDL control are encouraging but glycaemic control can be further improved.

Abstract
The incidence of chronic kidney disease (CKD) is on the rise in the USA. Cardiovascular events are the leading cause of death in this patient population, therefore reducing the risk of these events has become a major focus. The aim of this review is to assess current literature on the use of statins in CKD and end-stage renal disease. Cholesterol reduction is important in preventing the development and progression of coronary heart disease and its negative effects. Statins have been widely studied and proven to reduce cardiovascular risk in the general population. The information gained from trials has been extrapolated to special populations, including CKD, despite these patients often being excluded. However, recent studies have begun to focus on CKD, hemodialysis, and transplant patients and the use of cholesterol-lowering agents and the potential association with decreased cardiovascular events. In addition, due to the unique pharmacokinetic and pharmacodynamic changes that occur in these patients, choosing the appropriate cholesterol-lowering agent becomes important for both safety and efficacy. The complexity of CKD patients is an important consideration when choosing cholesterol-lowering medication. Patients with CKD are often on medications that may interact with many of the cholesterol-lowering agents. Ensuring drug interactions are minimized is essential to the prevention of adverse events from the medications.

Abstract
Cardiovascular (CV) morbidity and mortality increase with the severity of kidney disease, reaching 30 times higher mortality rates in dialysis patients compared with the general population. Although dyslipidemia is a well-established CV risk factor in the general population, the relationship between lipid disorders and CV risk in patients with chronic kidney disease (CKD) is less clear. Despite the clear evidence that statins reduce the risk of atherosclerotic events and death from cardiac causes in individuals without CKD, the use of statins in patients with kidney disease is significantly less frequent. For a long time, one of the explanations was the lack of a prospective, randomized, controlled study designed specifically to CKD patients. After recent publication of the data from Study of Heart and Renal Protection trial, given the safety and potential efficacy of statins, this lipid-lowering treatment should be administered more frequently to individuals with CKD stage 1-4, as well as those undergoing dialysis.

Abstract
BACKGROUND People with advanced kidney disease treated with dialysis experience mortality rates from cardiovascular disease that are substantially higher than for the general population. Studies that have assessed the benefits of statins (HMG CoA reductase inhibitors) report conflicting conclusions for people on dialysis and existing meta-analyses have not had sufficient power to determine whether the effects of statins vary with severity of kidney disease. Recently, additional data for the effects of statins in dialysis patients have become available. This is an update of a review first published in 2004 and last updated in 2009. OBJECTIVES To assess the benefits and harms of statin use in adults who require dialysis (haemodialysis or peritoneal dialysis). SEARCH METHODS We searched the Cochrane Renal Group's Specialised Register to 29 February 2012 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs that compared the effects of statins with placebo, no treatment, standard care or other statins on mortality, cardiovascular events and treatment-related toxicity in adults treated with dialysis were sought for inclusion. DATA COLLECTION AND ANALYSIS Two or more authors independently extracted data and assessed study risk of bias. Treatment effects were summarised using a random-effects model and subgroup analyses were conducted to explore sources of heterogeneity. Treatment effects were expressed as mean difference (MD) for continuous outcomes and risk ratios (RR) for dichotomous outcomes together with 95% confidence intervals (CI). MAIN RESULTS The risk of bias was high in many of the included studies. Random sequence generation and allocation concealment was reported in three (12%) and four studies (16%), respectively. Participants and personnel were blinded in 13 studies (52%), and outcome assessors were blinded in five studies (20%). Complete outcome reporting occurred in nine studies (36%). Adverse events were only reported in nine studies (36%); 11 studies (44%) reported industry funding.We included 25 studies (8289 participants) in this latest update; 23 studies (24 comparisons, 8166 participants) compared statins with placebo or no treatment, and two studies (123 participants) compared statins directly with one or more other statins. Statins had little or no effect on major cardiovascular events (4 studies, 7084 participants: RR 0.95, 95% CI 0.88 to 1.03), all-cause mortality (13 studies, 4705 participants: RR 0.96, 95% CI 0.90 to 1.02), cardiovascular mortality (13 studies, 4627 participants: RR 0.94, 95% CI 0.84 to 1.06) and myocardial infarction (3 studies, 4047 participants: RR 0.87, 95% CI 0.71 to 1.07); and uncertain effects on stroke (2 studies, 4018 participants: RR 1.29, 95% CI 0.96 to 1.72).Risks of adverse events from statin therapy were uncertain; these included effects on elevated creatine kinase (5 studies, 3067 participants: RR 1.25, 95% CI 0.55 to 2.83) or liver function enzymes (4 studies, 3044 participants; RR 1.09, 95% CI 0.41 to 1.25), withdrawal due to adverse events (9 studies, 1832 participants: RR 1.04, 95% CI 0.87 to 1.25) or cancer (2 studies, 4012 participants: RR 0.90, 95% CI 0.72 to 1.11). Statins reduced total serum cholesterol (14 studies, 1803 participants; MD -44.86 mg/dL, 95% CI -55.19 to -34.53) and low-density lipoprotein cholesterol (12 studies, 1747 participants: MD -39.99 mg/dL, 95% CI -52.46 to -27.52) levels. Data comparing statin therapy directly with another statin were sparse. AUTHORS' CONCLUSIONS Statins have little or no beneficial effects on mortality or cardiovascular events and uncertain adverse effects in adults treated with dialysis despite clinically relevant reductions in serum cholesterol levels.

Abstract
The inexorable increase in the prevalence of obesity is a global health concern, which will result in a concomitant escalation in health-care costs. Obesity-related metabolic syndrome affects approximately 25% of adults and is associated with cardiovascular and renal disease. The heart and kidneys are physiologically interdependent, and the pathological effects of obesity can lead to cardiorenal syndrome and, ultimately, kidney and heart failure. Weight loss can prevent or ameliorate obesity-related cardiorenal syndrome, but long-term maintenance of a healthy weight has been difficult to achieve through lifestyle changes or pharmacotherapy. Bariatric surgery offers both sustained weight loss and favourable metabolic changes, including dramatic improvements in glycaemic control and symptoms of type 2 diabetes mellitus. Procedures such as Roux-en-Y gastric bypass offer immediate multisystemic benefits, including bile flow alteration, reduced gastric size, anatomical gut rearrangement and altered flow of nutrients, vagal manipulation and enteric hormone modulation. In patients with cardiorenal syndrome, bariatric surgery also offers renoprotection and cardioprotection, and attenuates both kidney and heart failure by improving organ perfusion and reversing metabolic dysfunction. However, further research is required to understand how bariatric surgery acts on the cardiorenal axis, and its pioneering role in novel treatments and interventions for cardiorenal disease.

Abstract
The authors conducted a randomized, controlled, multicenter trial, in which they assigned well-controlled hypertensive participants aged 55 years and older with moderate hypercholesterolemia to receive pravastatin (n=5170) or usual care (n=5185) for 4 to 8 years, when trial therapy was discontinued. Passive surveillance using national databases to ascertain deaths and hospitalizations continued for a total follow-up of 8 to 13 years to assess whether mortality and morbidity differences persisted or new differences developed. During the post-trial period, fatal and nonfatal outcomes were available for 98% and 64% of participants, respectively. The primary outcome was all-cause mortality and the secondary outcomes included cardiovascular mortality, coronary heart disease (CHD), stroke, heart failure, cardiovascular disease, and end-stage renal disease. No significant differences appeared in mortality for pravastatin vs usual care (hazard ratio [HR], 0.96; 95% confidence interval [CI], 0.89-1.03) or other secondary outcomes. Similar to the previously reported in-trial result, there was a significant treatment effect for CHD in black patients (HR, 0.79; 95% CI, 0.64-0.98). However, the in-trial result showing a significant treatment by race effect did not remain significant during the entire follow-up (P=.08). These findings are consistent with evidence from other large trials that show statins prevent CHD and add evidence that they are effective for CHD prevention in black patients.

Abstract
BACKGROUND For chronic kidney disease (CKD) patients, national treatment guidelines recommend a low-density lipoprotein cholesterol (LDL-C) goal <100 mg/dL and blood pressure (BP) target <130/80 mmHg. This analysis assessed the current status of cardiovascular (CV) risk factor treatment and control in US adults with CKD. METHODS Weighted prevalence estimates of CV-related comorbidities, utilization of lipid- and BP-lowering agents, and LDL-C and BP goal attainment in US adults with CKD were assessed among 9,915 men and nonpregnant women aged ≥20 years identified from the fasting subsample of the 2001-2010 National Health and Nutritional Examination Survey (NHANES). Analyses were performed using SAS survey procedures that consider the complex, multistage, probability sampling design of NHANES. All estimates were standardized to the 2008 US adult population (≥20 years). Data were stratified by CKD stage based on presence of albuminuria and estimated glomerular filtration rate (eGFR), calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Stage 3 CKD was subdivided into 3a (eGFR 45-59 mL/min/1.73 m(2)) and 3b (eGFR 30-44 mL/min/1.73 m(2)); Stage 5 CKD and dialysis recipients were excluded. RESULTS Of the 9,915 NHANES participants identified for analysis, 1,428 had CKD (Stage 1-4), corresponding to a prevalence estimate for US adults aged ≥20 years of 10.2%. Prevalence of CV-related comorbidities increased markedly with CKD stage, with a ~6-12-fold increase in cardiovascular disease, coronary heart disease (CHD), stroke and congestive heart failure between CKD Stage 1 and 4; prevalence of diabetes, hyperlipidemia and hypertension increased by ~1.2-1.6-fold. Use of lipid-lowering agents increased with CKD stage, from 18.1% (Stage 1) to 44.8% (Stage 4). LDL-C goal attainment increased from 35.8% (Stage 1) to 52.8% (Stage 3b), but decreased in Stage 4 (50.7%). BP goal attainment decreased between Stage 1 and 4 (from 49.5% to 30.2%), despite increased use of antihypertensives (from 30.2% to 78.9%). CONCLUSIONS Individuals with CKD have a high prevalence of CV-related comorbidities. However, attainment of LDL-C or BP goals was low regardless of disease stage. These findings highlight the potential for intensive risk factor modification to maximize CV event reduction in CKD patients at high risk for CHD.

Abstract
OBJECTIVES The authors sought to evaluate the cost-effectiveness of statins for primary prevention of myocardial infarction (MI) and stroke in patients with chronic kidney disease (CKD). BACKGROUND Patients with CKD have an elevated risk of MI and stroke. Although HMG Co-A reductase inhibitors (“statins”) may prevent cardiovascular events in patients with non–dialysis-requiring CKD, adverse drug effects and competing risks could materially influence net effects and clinical decision-making. METHODS We developed a decision-analytic model of CKD and cardiovascular disease (CVD) to determine the cost-effectiveness of low-cost generic statins for primary CVD prevention in men and women with hypertension and mild-to-moderate CKD. Outcomes included MI and stroke rates, discounted quality-adjusted life years (QALYs) and lifetime costs (2010 USD), and incremental cost-effectiveness ratios. RESULTS For 65-year-old men with moderate hypertension and mild-to-moderate CKD, statins reduced the combined rate of MI and stroke, yielded 0.10 QALYs, and increased costs by $1,800 ($18,000 per QALY gained). For patients with lower baseline cardiovascular risks, health and economic benefits were smaller; for 65-year-old women, statins yielded 0.06 QALYs and increased costs by $1,900 ($33,400 per QALY gained). Results were sensitive to rates of rhabdomyolysis and drug costs. Statins are less cost-effective when obtained at average retail prices, particularly in patients at lower CVD risk. CONCLUSIONS Although statins reduce absolute CVD risk in patients with CKD, the increased risk of rhabdomyolysis, and competing risks associated with progressive CKD, partly offset these gains. Low-cost generic statins appear cost-effective for primary prevention of CVD in patients with mild-to-moderate CKD and hypertension.

Abstract
Renovascular hypertension refers to the rise of arterial pressure due to reduced perfusion of the kidney caused by the stenotic renal artery/ies. The most common cause of stenotic renal artery is atherosclerosis. Atherosclerotic renal stenosis is usually part of a systemic syndrome that involves hypertension, intrinsic renal damage, and cardiovascular morbidity. So far, large trials have not proven the superiority of interventional therapies to medical management. As a result, renal artery stenosis should be treated mainly as a coronary artery disease equivalent focusing on rigorous management of hypertension, hyperglycemia, and hyperlipidemia. Antihypertensive treatment should include renin-angiotensin system blockade medication in most cases, while HMG-CoA reductase inhibitors (statins) can be used even in chronic kidney disease with safety. Lifestyle modifications, such as cessation of smoking, and antiplatelet therapy have reduced the risk of cardiovascular events in high-risk patients.

Diabetes is a leading cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) in developed nations, including Japan and the United States. Japan has the unenviable distinction of having one of the world's highest rates of dialysis: in 2011, there were over 300,000 dialysis patients (2,383 per million people), with diabetic patients accounting for almost half of all incident cases. Concomitance of CKD and diabetes predicts a greater risk of cardiovascular disease (CVD) than either condition in isolation. Hence, appropriate management of modifiable cardiovascular (CV) risk factors, including dyslipidemia, is paramount in this high-risk group. The United States and Japan have distinct approaches to cholesterol management, with more stringent therapeutic targets for lipid control advocated in US guidelines. However, upward trends in cholesterol levels and coronary heart disease incidence in Japan may provide justification for more intensive CV risk factor management strategies by Japanese physicians to achieve maximum benefit. Attainment of recommended lipid goals in Japan is poor, particularly in patients with diabetes and/or CKD in whom CV risk factors are often undertreated. Statin therapy has been shown to be safe and effective in reducing CV risk in patients with diabetes and/or CKD stages 1-5. Moreover, statins may impart a renoprotective effect by preventing or delaying progressive loss of kidney function. This review summarizes evidence from studies in Western and Japanese populations to highlight the CV and renal benefits of lipid-lowering agents in CKD patients, including those with diabetes.

Abstract
Multiple studies demonstrate a strong independent association between CKD and cardiovascular events including death, heart failure, and myocardial infarction. This review focuses on recent clinical studies that expand this spectrum of adverse cardiovascular events to include ventricular arrhythmias and sudden cardiac death. In addition, experimental models suggest structural remodeling of the heart and electrophysiologic changes in this population. These processes may explain the increased arrhythmic risk in kidney disease and aid in identifying patients who are at higher risk for sudden cardiac death. Finally, we review here the data to support the use of pharmacologic and device-based therapies for both the primary and secondary prevention of sudden cardiac death.

Abstract
The relationship between obesity, diabetes, hyperlipidemia, hypertension, kidney disease and cardiovascular disease (CVD) is established when looked at from a clinical, epidemiological or pathophysiological perspective. Yet, when viewed from a genetic perspective, there is comparatively little data synthesis that these conditions have an underlying relationship. We sought to investigate the overlap of genetic variants independently associated with each of these commonly co-existing conditions from the NHGRI genome-wide association study (GWAS) catalog, in an attempt to replicate the established notion of shared pathophysiology and risk. We used pathway-based analyses to detect subsets of pleiotropic genes involved in similar biological processes. We identified 107 eligible GWAS studies related to CVD and its established comorbidities and risk factors and assigned genes that correspond to the associated signals based on their position. We found 44 positional genes shared across at least two CVD-related phenotypes that independently recreated the established relationship between the six phenotypes, but only if studies representing non-European populations were included. Seven genes revealed pleiotropy across three or more phenotypes, mostly related to lipid transport and metabolism. Yet, many genes had no relationship to each other or to genes with established functional connection. Whilst we successfully reproduced established relationships between CVD risk factors using GWAS findings, interpretation of biological pathways involved in the observed pleiotropy was limited. Further studies linking genetic variation to gene expression, as well as describing novel biological pathways will be needed to take full advantage of GWAS results.

Abstract
This is a case report that describes a 67-year-old woman with mixed hyperlipidemia and diabetic nephropathy. She was initially prescribed a combination of simvastatin plus gemfibrozil by her general practitioner (GP). When referred to our cardiovascular unit, we further diagnosed the patient to have mixed hyperlipidemia and rhabdomyolysis. Because of concerns with her chronic kidney disease (CKD), we temporarily stopped all her drug treatments and started insulin treatment for her type 2 diabetes (T2D). A month later when her T2D was stabilised, we prescribed atorvastatin and an omega-3 fatty acid ethyl ester supplement to treat her hypertriglyceridemia. Within two months her blood lipids were within the recommended range. In patients with stage 3–5 CKD, it is not advisable to prescribe the fibrate gemfibrozil, particularly in combination with a statin that is metabolised predominantly in the kidneys. To minimise adverse events without compromise on efficacy, we used a combination of omega-3 fatty acid ethyl esters, which are not metabolised in the kidneys, with a statin that is minimally metabolised in the kidneys for the treatment of her hyperlipidemia.

Abstract
BACKGROUND Statins have uncertain benefits in persons with chronic kidney disease (CKD) because individual trials may have insufficient power to determine whether treatment effects differ with severity of CKD. PURPOSE To summarize the benefits and harms of statin therapy for adults with CKD and examine whether effects of statins vary by stage of kidney disease. DATA SOURCES Cochrane and EMBASE databases (inception to February 2012). STUDY SELECTION Randomized trials comparing the effects of statins with placebo, no treatment, or another statin on mortality and cardiovascular outcomes. DATA EXTRACTION Two independent reviewers extracted data and assessed risk of bias. DATA SYNTHESIS Eighty trials comprising 51099 participants compared statin with placebo or no treatment. Treatment effects varied with stage of CKD. Moderate- to high-quality evidence indicated that statins reduced all-cause mortality (relative risk [RR], 0.81 [95% CI, 0.74 to 0.88]), cardiovascular mortality (RR, 0.78 [CI, 0.68 to 0.89]), and cardiovascular events (RR, 0.76 [CI, 0.73 to 0.80]) in persons not receiving dialysis. Moderate- to high-quality evidence indicated that statins had little or no effect on all-cause mortality (RR, 0.96 [CI, 0.88 to 1.04]), cardiovascular mortality (RR, 0.94 [CI, 0.82 to 1.07]), or cardiovascular events (RR, 0.95 [CI, 0.87 to 1.03]) in persons receiving dialysis. Effects of statins in kidney transplant recipients were uncertain. Statins had little or no effect on cancer, myalgia, liver function, or withdrawal from treatment, although adverse events were evaluated systematically in fewer than half of the trials. LIMITATION There was a reliance on post hoc subgroup data for earlier stages of CKD. CONCLUSION Statins decrease mortality and cardiovascular events in persons with early stages of CKD, have little or no effect in persons receiving dialysis, and have uncertain effects in kidney transplant recipients.

Abstract
BACKGROUND Chronic renal failure on dialysis can reduce the number of circulating endothelial progenitor cells (EPCs), but this biomarker has not been fully investigated in patients with chronic kidney disease (CKD). A link between CKD and increased mononuclear cell apoptosis (MCA) in circulation has been reported but the effect of vascular endothelial growth factor (VEGF) and stromal cell-derived factor (SDF)-1α, two angiogenesis factors, on circulating EPC levels in CKD has not been clarified. This study examined the relationships between the numbers of circulating EPCs and the severity of CKD, degree of MCA and serum levels of VEGF and SDF-1α in CKD patients. METHODS The numbers of circulating EPCs (CD31/CD34+, CD62E/CD34+, KDR/CD34+, CXCR4/CD34+) were measured in 166 patients with varying degrees of CKD under regular treatment at an outpatient department and in 30 volunteer control subjects. RESULTS CKD patients had significantly lower numbers of EPCs (p < 0.007), higher MCA in circulation and higher serum levels of VEGF and SDF-1 compared with the control subjects (all p < 0.001). Compared with patients with early CKD (stages I-III), patients with late CKD [stage IV-V or end-stage renal disease (ESRD)] had significantly lower numbers of EPCs (CXCR4/CD34+), higher MCA, and elevated serum levels of VEGF and SDF-1α (all p < 0.01). Serum VEGF level but not MCA or SDF-1α was strongly correlated with increased numbers of circulating EPCs. Multivariate analysis showed that ESRD along with lower serum albumin was independently predictive of lower numbers of circulating EPCs (p < 0.04). CONCLUSION Circulating EPCs were markedly reduced in CKD patients. ESRD was strongly and independently predictive of decreased numbers of circulating EPCs.

Abstract
BACKGROUND Previous studies show that statins reduce total cholesterol (TC) concentration by both 21% in primary prevention (PP) and secondary prevention (SP) in clinical trials and by ∼24% in the general population. There are few data about the efficacy of statins on TC concentration and cardiovascular (CV) outcome in patients with chronic kidney disease (CKD). We evaluated the reduction of TC concentration and subsequent risk of CV morbidity and mortality with statins in CKD patients. METHODS A population-based cohort study using a record-linkage database in Tayside, Scotland. A total of 2369 patients who had a primary diagnosis of CKD from Scottish Morbidity Record data or biochemistry database (serum creatinine of 220 μmol/l or higher) and who had at least two separate TC measurements between 1993 and 2007 were studied. Patients were categorized into statin-exposed and statin-unexposed groups according to statin use status during the follow-up. They were also classified into PP (n = 1325) and SP (n = 1044) cohorts at the entry date. The main outcomes were TC concentration change from baseline, CV events [Antiplatelet Trialist's Collaboration (APTC)] and all-cause mortality during the follow-up. Cox regression models, in which statin use was a time-dependent variable, were employed to assess the risk of outcome and adjusted for other known confounders. RESULTS Statin-associated TC concentrations decreased by 0.59 mmol/l (12%) in PP cohort and 0.56 mmol/l (13%) in SP cohort from 4.77 and 4.48 mmol/l at baselines, respectively. Statin use was associated with a reduced risk of APTC events, CV mortality or all-cause mortality in PP {adjusted hazard ratio (HR), 0.65 [95% confidence interval (CI) 0.48-0.88]; 0.73 (95% CI 0.52-0.98); 0.59 (95% CI 0.48-0.73)} and SP [adjusted HR, 0.66 (95% CI 0.52-0.84); 0.60 (95% CI 0.47-0.77); 0.56 (95% CI 0.47-0.68)], respectively. CONCLUSION Statin use reduced TC concentrations by ∼13% in patients with CKD. Statins were protective of APTC events, CV mortality and all-cause mortality in patients with or without established CV disease.

Effects of statins on cardiorenal syndrome. Int J Vasc Med 2012; 2012:162545.

Abstract
Cardiovascular disease and renal disease have a close relationship that forms a vicious cycle as a cardiorenal syndrome (CRS). Oxidative stress, endothelial dysfunction, and vascular inflammation could be therapeutic targets when the renin-angiotensin-aldosterone system is activated by accumulation of conventional cardiovascular risk factors; however, a strategy for management of CRS has not been established yet. Statins, HMG-CoA reductase inhibitors, have not only cholesterol-lowering effects but also pleiotropic effects on cardiovascular systems, including anti-inflammatory and antioxidant effects and improvement of nitric oxide bioavailability. Since recent studies have indicated that statins have beneficial effects on chronic kidney disease and heart failure as well as coronary artery disease in cholesterol-lowering-dependent/independent manners, treatment with statins might be a successful strategy for preventing deterioration of CRS.

Abstract
BACKGROUND An elevated triglyceride level is associated with cardiovascular and all-cause mortality in the general population. The associations between serum triglyceride and all-cause mortality among patients with chronic kidney disease (CKD) are unclear. METHODS Patients with Stage 3 and Stage 4 CKD (estimated glomerular filtration rate 15-59 mL/min/1.73 m(2)) who had serum triglycerides measured prior to being classified as CKD were included. We examined the associations of serum triglyceride levels with all-cause mortality among 25 641 Stage 3 and Stage 4 CKD patients using Cox proportional hazard models and Kaplan-Meier survival curves. RESULTS In the Cox model, after adjusting for relevant covariates including other lipid parameters, serum triglyceride level 150-199 mg/dL was not associated with death [hazard ratio (HR) 1.00, 95% confidence interval (95% CI) 0.92-1.10] relative to serum triglyceride <150 mg/dL while serum triglyceride ≥ 200 mg/dL was associated with a 11% increased hazard for death (95% CI 1.01-1.22). Age modified the association between serum triglyceride levels ≥ 200 mg/dL and mortality with patients <65 years having a 38% higher hazard for death (95% CI 1.15-1.65) and ≥ 65 years with no increased risk for death (HR 0.97, 95% CI 0.88-1.08, P for interaction <0.001). When serum triglycerides were examined as a continuous log-transformed variable, similar associations with mortality were noted. CONCLUSIONS Serum triglyceride ≥ 200 mg/dL was independently associated with all-cause mortality in Stage 3 and Stage 4 CKD patients aged <65 years but not among patients of age ≥ 65 years. Future studies should confirm these findings and examine the mechanisms that may explain these associations.

Abstract
BACKGROUND Diabetic kidney disease (DKD) is associated with increased morbidity and mortality, mostly relating to cardiovascular complications. The relevance of inflammation in the pathogenesis of DKD has been investigated in recent years, and it has been shown that inflammatory markers are higher in people with DKD compared with the wider population. Pentoxifylline is a methylxanthine phosphodiesterase inhibitor with favourable anti-inflammatory effects and immunoregulatory properties. The anti-inflammatory effects conferred by pentoxifylline may be beneficial in the management of DKD. OBJECTIVES To assess the benefits and harms of pentoxifylline for treating people with DKD. SEARCH METHODS We searched the Cochrane Renal Group's specialised register (January 2012), CENTRAL (Issue 12, 2011), MEDLINE, EMBASE and four Chinese biomedical literature databases (CBM-disc, 1979 to July 2009), Chinese Science and Technique Journals Database (VIP, until July 2009), China National Knowledge Infrastructure (CNKI, until July 2009) and WanFang database (until July 2009). SELECTION CRITERIA All randomised controlled trials (RCTs) and quasi-RCTs studying the benefits and harms of pentoxifylline for DKD. DATA COLLECTION AND ANALYSIS Data were extracted independently by two authors. Meta-analyses were performed when more than one study provided data on a comparable outcome in sufficiently similar patients. Results of dichotomous outcomes were expressed as risk ratios (RR) with 95% confidence intervals (CI). Mean differences (MD) were calculated to assess the effects of treatment where outcomes were expressed on continuous scales, and standardised mean differences (SMD) calculated where different scales were used. Data was pooled using the random effects model. Adverse effects were assessed using descriptive techniques and where possible, risk differences (RD) with 95% CI. MAIN RESULTS We identified 17 studies that included a total of 991 participants with DKD which met our inclusion criteria. Overall, the methodological quality of included studies was low: 4/17 reported the method of randomisation, 13/17 did not; no study described the method of random allocation; 4/17 studies were considered to be at high risk of bias and 13/17 were considered to have unclear risk for incomplete outcome data reporting; 9/17 studies were at low risk bias and in 8/17 the risk of bias was unclear for selective outcome reporting.Compared with placebo, pentoxifylline significantly reduced serum creatinine (SCr) (MD -0.10 mg/dL, 95% CI -0.17 to -0.03), albuminuria (SMD -2.28, 95% CI -3.85 to -0.70) and overt proteinuria (MD -428.58 µg/min, 95% CI -661.65 to -195.50), but there was no difference in creatinine clearance (CrCl) (MD -5.18 mL/min, 95% CI -15.55 to 5.19). When compared with routine treatment alone, pentoxifylline did not significantly reduce SCr (MD 0.00 mg/dL, 95% CI -0.06 to 0.07) or blood pressure (systolic (SBP): MD -0.28 mm Hg, 95% CI -2.20 to 1.63; diastolic (DBP): MD -0.15 mm Hg, 95% CI -1.44 to 1.14), but did significantly reduce albuminuria (SMD 0.62, 95% CI 0.18 to 1.07) and proteinuria (MD 0.46 g/24 h, 95% CI 0.17 to 0.74). There was no significant difference in SCr (MD 0.00 mg/dL, 95% CI -0.08 to 0.07), albuminuria (MD -8.79 µg/min, 95% CI -27.18 to 9.59), proteinuria (MD -0.01 g/24 h, 95% CI -0.03 to 0.01) or blood pressure (SBP: MD 1.46 mm Hg, 95% CI -0.57 to 3.50; DBP: MD 1.37 mm Hg, 95% CI -0.23 to 2.98) between pentoxifylline and the active comparator (captopril or clonidine/methyldopa) for patients with type 1 and type 2 DKD. CrCl was significantly increased when pentoxifylline was compared to clonidine/methyldopa (MD 10.90 mL/min, 95% CI -1.40 to 20.40) but not with captopril (MD 3.26 mL/min, 95% CI -1.05 to 7.59). No data were available on the incidence of end-stage kidney disease (ESKD), time to ESKD, quality of life, or all-cause mortality. The adverse events of pentoxifylline were mild; no serious adverse events were reported in any of the included studies. AUTHORS' CONCLUSIONS From the available evidence, pentoxifylline seems to offer some beneficial effects in renal function improvement and reduction in albuminuria and proteinuria, with no obvious serious adverse effects for patients with DKD. However, most studies were poorly reported, small, and methodologically flawed. Evidence to support the use of pentoxifylline for DKD was insufficient to develop recommendations for its use in this patient population. Rigorously designed, randomised, multicentre, large scale studies of pentoxifylline for DKD are needed to further assess its therapeutic effects.
