Abstract
Patients with combined cardiac and renal diseases are particularly challenging in the routine clinical practice due to the substantial risk profile for increased morbidity and mortality. As cardiorenal patients have often been underrepresented in randomized, controlled interventional trials, guideline recommendations regarding the choice of treatment are often weaker for these individuals than for cardiovascular patients without chronic kidney disease. Furthermore, there are limitations in the approval of certain medications depending on the kidney function. This review addresses some considerations in crucial treatment areas for patients with cardiovascular diseases, whose treatment is significantly influenced by concomitant chronic kidney disease.

Abstract
Malnutrition is highly prevalent in dialysis patients and associated with poor outcomes. In 2008, protein-energy wasting (PEW) was coined by the International Society of Renal Nutrition and Metabolism (ISRNM), as a single pathological condition in which undernourishment and hypercatabolism converge. In 2014, a new simplified score was described using serum creatinine adjusted for body surface area (sCr/BSA) to replace a reduction of muscle mass over time in the muscle wasting category. We have now compared PEW-ISRNM 2008 and PEW-score 2014 to evaluate the prevalence of PEW and the risk of death in 109 haemodialysis patients. This was a retrospective analysis of cross sectional data with a median prospective follow-up of 20 months. The prevalence of PEW was 41 % for PEW-ISRNM 2008 and 63 % for PEW-score 2014 (P <0·002). Using PEW-score 2014: twenty-nine patients (27 %) had severe malnutrition (PEW-score 2014 0-1) and forty (37 %) with moderate malnutrition (score 2). Additionally, thirty-three (30 %) patients had mild wasting and only seven patients (6 %) presented a normal nutritional status. sCr/BSA correlated with lean total mass (R 0·46. P<0·001). A diagnosis of PEW according to PEW-score 2014, but not according to PEW-ISRNM 2008, was significantly associated with short-term mortality (P=0·0349) in univariate but not in multivariate analysis (P=0·069). In conclusion, the new PEW-score 2014 incorporating sCr/BSA identifies a higher number of dialysis PEW patients than PEW-ISRNM 2008. Whereas PEW-score-2014 provides timelier and therefore more clinically relevant information, its association with early mortality needs to be confirmed in larger studies.

Diagnostic Usefulness of the Protein Energy Wasting Score in Prevalent Hemodialysis Patients. J Ren Nutr 2018; 28:428-434.

Abstract
OBJECTIVE To study whether the score proposed by the International Society of Renal Nutrition and Metabolism to define the protein energy wasting (PEW) syndrome has diagnostic validity in patients undergoing dialysis. DESIGN AND METHODS Cross-sectional study including 468 prevalent hemodialysis patients from Canary Islands, Spain. Individual PEW syndrome criteria and the number of PEW syndrome categories were related to other objective markers of PEW using linear and logistic regression analyses: subjective global assessment, handgrip strength, bioimpedance-assessed body composition, and levels of high-sensitivity C-reactive protein. RESULTS Study participants (34% women) had a median age of 66 years, 37 months of maintenance dialysis, and 50% were diabetics. About 23% of patients had PEW (≥3 PEW categories), and 68% were at risk of PEW (1-2 PEW categories). Low prealbumin was the most frequently found derangement (52% of cases), followed by low albumin (46%), and low protein intake (35%). Across higher number of PEW syndrome categories, patients showed a longer dialysis vintage and had lower creatinine, triglycerides, and transferrin (P for trend <.001 for all). All nutritional assessments not included in the PEW definition worsened across higher number of PEW categories. In multivariable regression analyses, there was a linear inverse relationship between muscle and fat mass as well as handgrip strength with the number of PEW syndrome categories. Likewise, the proportion of subjective global assessment-defined malnutrition and serum concentration of C-reactive protein gradually increased despite adjustment for confounders (P for trend <.05 for all). CONCLUSION The PEW score reflects systemic inflammation, malnutrition and wasting among dialysis patients and may thus be used for diagnostic purposes.

Abstract
Acid-base and electrolyte alterations are common in patients with chronic kidney disease (CKD) and end-stage kidney failure (ESRD). The alterations become more complex as CKD advances to ESRD, leading to morbidity and mortality. Three cases are presented illustrating some key prototypic features in CKD and ESRD. Each is accompanied by discussion of pathophysiology, diagnosis, and treatment options. Newer investigational results are integrated into the existing body of knowledge. Although rigorous assessment of various dialysis prescriptions is scanty, in its current state, instituting a well thought-out, multi-pronged management plan to minimize CKD/ESRD and dialysis-related electrolyte and acid-base disruptions is appropriate. There is a pressing need for prospective interventional trials in the future.

Abstract
PURPOSE OF REVIEW This review article focuses on the most significant cardiovascular complications in dialysis patients [sudden cardiac death (SCD), acute coronary syndromes, heart failure, and atrial fibrillation]. RECENT FINDINGS Current and ongoing research aims to quantify the rate and pattern of significant arrhythmia in dialysis patients and to determine the predominant mechanism of SCD. Preliminary findings from these studies suggest a high rate of atrial fibrillation and that bradycardia and asystole may be more frequent than ventricular arrhythmia as a cause of sudden death. A recently published matched cohort study in dialysis patients who received a defibrillator for primary prevention showed that there was no significant difference in mortality rates between defibrillator-treated patients and propensity-matched controls. Two randomized controlled trials are currently recruiting participants and will hopefully answer the question of whether implantable or wearable cardioverter defibrillators can prevent SCD. An observational study using United States Renal Data System data demonstrated how difficult it is to keep hemodialysis patients on warfarin, as more than two-thirds discontinued the drug during the first year. The ISCHEMIA-CKD trial may provide answers about the optimal strategy for the treatment of atherosclerotic coronary disease in patients with advanced chronic kidney disease. SUMMARY The article reviews the diagnosis of acute coronary syndromes in dialysis patients, current literature on myocardial revascularization, and data on fatal and nonfatal cardiac arrhythmia. The new classification of heart failure in end-stage renal disease is reviewed. Finally, available cohort studies on warfarin for stroke prevention in dialysis patients with atrial fibrillation are reviewed.

Abstract
Although organ transplantation is the definitive treatment for end-stage organ failure, the post-transplant outcomes can be substantially influenced by cardiovascular complications. A national cohort study was performed to estimate risks of cardiovascular diseases in those with heart, lung, kidney, and liver transplantation. This cohort study consisted of 5978 solid organ transplantations identified using the Taiwan National Health Insurance Database. Cardiovascular and mortality risks in transplant recipients were evaluated using standardized incidence ratios, excess absolute risks, and standardized mortality ratios as compared to those in the general population. In heart, kidney, and liver recipients, the standardized incidence ratios of overall cardiovascular diseases were 9.41 (7.75-11.44), 3.32 (2.29-3.77), and 1.4 (1.15-1.7) and the overall standardized mortality ratios were 5.23 (4.54-6.03), 1.48 (1.34-1.63), and 3.95 (3.64-4.28), respectively. Except for heart organ recipients who were at highest risk for coronary artery disease with a standardized incidence ratio of 13.12 (10.57-16.29), kidney and liver organ recipients had a ninefold increased risk in developing deep vein thrombosis post-transplant. In conclusion, solid organ transplant patients are at risk of cardiovascular disease, in particular, deep vein thrombosis, which may warrant early identification of high-risk patients in addition to prompt and adequate thromboprophylaxis perioperatively.

Abstract
BACKGROUND Chronic kidney disease is associated with a 15-fold increase in the risk of death and a 30-fold increase in the risk of cardiovascular events even prior to dialysis initiation, and this situation remains unchanged following the initiation of the dialysis procedure. Lipoprotein structure and function, especially the anti-oxidative properties of high-density lipoprotein, are altered. In this study, the effectiveness of lipid-lowering therapy on mortality and cardiovascular outcomes is explored. SUMMARY Mortality is inversely associated with the cholesterol level. The degree of inflammation and wasting is a stronger predictor of mortality than are cholesterol levels. Treatment with statins reduces the risk of death and cardiovascular outcomes among patients not yet requiring renal replacement therapy, but is not effective once dialysis is initiated, most likely because other processes, such as inflammation, not affected by lipid-lowering therapy, dominate in the causal pathway leading to adverse outcomes. Fenofibrate is also useful in reducing cardiovascular outcomes and the progression of renal disease among patients with type 2 diabetes not yet requiring dialysis. While the lipid-lowering therapy is effective in patients with the nephrotic syndrome, no long-term outcome studies regarding hard outcomes are available. KEY POINTS The great increase in cardiovascular outcomes in patients with kidney disease is likely due to a consequence of properties that are unresponsive to the lipid-lowering therapy, most likely inflammation. The lipid-lowering therapy is useful in patients who are not yet in need of dialysis but does not reduce mortality in dialysis patients.

Abstract
BACKGROUND Protein-energy wasting (PEW) is common in patients undergoing hemodialysis (HD). Studies have assessed the positive effect of oral nutritional supplementation (ONS) or resistance exercise (RE) on nutritional status (NS) markers in patients undergoing HD. METHODS The aim of this study was to assess the effect of ONS and RE on NS and the quality of life (QOL) of 36 patients undergoing HD. In a randomized clinical trial, patients were divided into the following two groups: a control group (ONS) that received a can of ONS during their HD sessions and an intervention group (ONS + RE) that received a can of ONS and underwent a 40-min session of RE during their HD sessions. Both interventions lasted 12 weeks. The patients' anthropometric, biochemical, dietetic and bioelectrical impedance measurements as well as their QOL, evaluated using the Kidney Disease Quality of Life Short Form, were recorded. RESULTS At baseline, 55.5% of patients presented with PEW according to International Society of Renal Nutrition and Metabolism criteria (20 patients). We found statistically significant changes from baseline in both groups, such as increases in body weight, body mass index, midarm circumference, midarm muscle circumference, triceps skinfold thickness, fat mass percentage, handgrip strength, phase angle and serum albumin. A decrease in the prevalence of PEW was observed in both groups at the end of the intervention. A delta comparison between groups showed no statistically significant differences in the anthropometric and biochemical parameters. No significant improvement was observed in QOL and body composition measured by bioimpedance vector analysis. Dietary energy and protein intake increased significantly during the study period for all patients. CONCLUSION Oral nutritional supplementation during HD improves NS. The addition of RE during HD does not seem to augment the acute anabolic effects of intradialytic ONS on NS.

Abstract
Sudden cardiac death, which causes premature loss of lives on haemodialysis of the elderly, youths and even children; cannot be prevented, because the aetiology is poorly understood and effective interventions are yet unknown. Improving our knowledge of mechanisms causing sudden cardiac death in haemodialysis patients may help us to design better interventions; and clinical epidemiology of sudden cardiac death could be an important tool to further guide human and animal studies. This review researches the clinical epidemiology of sudden cardiac death to suggest possible mechanisms, although they require further studies. The research shows how traditional cardiovascular risk factors such as age, diabetes and smoking have an impact; non-traditional risk factors such as inflammation, mineral-bone disease and even uraemia itself have higher impact; and how cardiac structural, functional and electrocardiographic markers predict sudden cardiac death in dialysis patients. More in-depth human and animal studies, guided with existing knowledge, are necessary to better understand the mechanisms and design successful interventions.

Abstract
BACKGROUND Dialysis patients have high rates of cardiovascular morbidity and mortality, but data on arrhythmia burden, arrhythmia type, arrhythmia triggers, and the identity of terminal arrhythmias have historically been limited by an inability to monitor heart rhythm for prolonged periods. OBJECTIVES To investigate arrhythmia and its association with sudden death in dialysis-dependent ESRD, describe the potential for implantable devices to advance study of dialysis physiology, review the ethical implications of using implantable devices in clinical studies, and report on the protocol and baseline results of the Monitoring in Dialysis Study (MiD). DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS In this multicenter, interventional-observational, prospective cohort study, we placed implantable loop recorders in patients undergoing long-term hemodialysis. The proportion of patients experiencing clinically significant arrhythmias was the primary endpoint. For 6 months, we captured detailed data on the primary endpoint, symptomatic arrhythmias, other electrocardiographic variables, dialysis prescription, electrolytes, dialysis-related variables, and vital signs. We collected additional electrocardiographic data for up to 1 year. RESULTS Overall, 66 patients underwent implantation in sites in the United States and India. Diabetes was present in 63.6% of patients, 12.1% were age ≥70 years, 69.7% were men, and 53.0% were black. Primary and secondary endpoint data are expected in 2016. CONCLUSIONS Cardiac arrhythmia is an important contributor to cardiovascular morbidity and mortality in dialysis patients, but available technology has previously limited the ability to estimate its true burden and triggers and to define terminal rhythms in sudden death. Use of implantable technology in observational studies raises complex issues but may greatly expand understanding of dialysis physiology. The use of implantable loop recorders in MiD is among the first examples of such a trial, and the results are expected to provide novel insights into the nature of arrhythmia in hemodialysis patients.

Abstract
The inextricable link between the heart and the kidneys predestines that significant cardiovascular disease ensues in the face of end-stage renal disease (ESRD). As a point of fact, the leading cause of mortality of patients on dialysis is still from cardiovascular etiologies, albeit differing in particular types of disease from the general population. For example, sudden cardiac death outnumbers coronary artery disease in patients with ESRD, which is the reverse for the general population. In this review, we will focus on the pathophysiology and treatment options of important traditional and nontraditional risk factors for cardiovascular disease in ESRD patients such as hypertension, anemia, vascular calcification, hyperparathyroidism, uremia, and oxidative stress. The evidence of erythropoietin-stimulating agents, phosphate binders, calcimimetics, and dialysis modalities will be presented. We will then discuss how these risk factors may be changed and perhaps exacerbated after renal transplantation. This is largely due to the immunosuppressive agents that are both crucial yet potentially detrimental in the posttransplant state. Calcineurin inhibitors, corticosteroids, and mammalian target of rapamycin inhibitors, the mainstay of transplant immunosuppression, are all known to increase the risks of developing new onset diabetes as well as the metabolic syndrome. Thus, we need to carefully negotiate between patients' cardiovascular profile and their risks of rejection. Finally, we end by considering strategies by which we may minimize cardiovascular disease in the transplant population, as this modality still confers the highest chance of survival in patients with ESRD.

Abstract
Patients undergoing hemodialysis have a 10 to 20 times higher risk of sudden cardiac arrest (SCA) than the general population. Sudden cardiac death is a rare event (approximately 1 event per 10,000 sessions) but has a very high mortality rate. Epidemiological data comes almost exclusively from North American studies; there is a great lack of European data on the subject. Ventricular arrhythmia is the main mechanism of sudden cardiac deaths in dialysis patients. These patients develop increased sensitivity mainly due to a high prevalence of severe ischemic heart disease and left ventricular hypertrophy and to a frequent trigger event: electrolytic and plasma volume shifts during dialysis sessions. Unfortunately, accurate predictive markers of SCA do not exist, however some primary prevention trials using beta-blockers or angiotensin II receptor blockers are encouraging, while the use of implantable cardioverter defibrillators in the population of chronic dialysis patients remains controversial. Identification of patients at risk, minimizing trigger events such as electrolytic shifts and improving team skills in the diagnosis and initial resuscitation with the latest recommendations from 2010 seem necessary to reduce incidence and improve survival in this high risk population. Organization of European studies would also allow a more accurate view of this reality in our dialysis units.

Abstract
BACKGROUND Dose requirements of erythropoietin-stimulating agents (ESAs) can vary considerably over time and may be associated with cardiovascular outcomes. We aimed to longitudinally assess ESA responsiveness over time and to investigate its association with specific clinical end points in a time-dependent approach. METHODS The German Diabetes and Dialysis study (4D study) included 1,255 diabetic dialysis patients, of whom 1,161 were receiving ESA treatment. In those patients, the erythropoietin resistance index (ERI) was assessed every 6 months during a median follow-up of 4 years. The association between the ERI and cardiovascular end points was analyzed by time-dependent Cox regression analyses with repeated ERI measures. RESULTS Patients had a mean age of 66 ± 8.2 years; 53% were male. During follow-up, a total of 495 patients died, of whom 136 died of sudden death and 102 of infectious death. The adjusted and time-dependent risk for sudden death was increased by 19% per 5-unit increase in the ERI (hazard ratio, HR = 1.19, 95% confidence interval, CI = 1.07-1.33). Similarly, mortality increased by 25% (HR = 1.25, 95% CI = 1.18-1.32) and infectious death increased by 27% (HR = 1.27, 95% CI = 1.13-1.42). Further analysis revealed that lower 25-hydroxyvitamin D levels were associated with lower ESA responsiveness (p = 0.046). CONCLUSIONS In diabetic dialysis patients, we observed that time-varying erythropoietin resistance is associated with sudden death, infectious complications and all-cause mortality. Low 25-hydroxyvitamin D levels may contribute to a lower ESA responsiveness.

Abstract
Background Low serum sodium (Na) has been associated with decreased body mass index and increased cardiovascular mortality in haemodialysis (HD) patients. We examined the relationship between serum Na and selected nutritional parameters of protein energy wasting that are not affected from the hydration status in a cohort of HD patients. Methods Triceps skinfold thickness (TSF), mid-arm circumference (MAC), mid-arm muscle circumference (MAMC), handgrip strength (HGS) and subjective global assessment (SGA) were assessed in maintenance HD patients using standard techniques. MAMC was calculated with the formula MAMC (cm) = MAC (cm) −3.142 × TSF cm. Pre-dialysis serum Na values from routine monthly laboratory measurements were averaged for the last 6 months prior to the nutritional assessment. Results Altogether 172 patients with anthropometric data were included in the final analysis. Mean age was 66 ± 14, females 62 (36%) and diabetics 48 (28.9%). Patients with pre-dialysis serum Na below the mean value (136.2 mEq/L) had lower MAMC, HGS, SGA scores and albumin levels (23.50 ± 3.16 cm versus 24.58 ± 3.71 cm, P = 0.048; 21.7 ± 13.6 kg versus 28.0 ± 12.4 kg, P = 0.030; 5.1 ± 1.2 versus 5.7 ± 1.0, P = 0.012 and 31.65 ± 4.73 mg/L versus 32.25 ± 3.91 mg/L, P = 0.022, respectively) and higher interdialytic weight gains. Pre-dialysis serum Na correlated positively with MAMC, handgrip and SGA (Pearson's correlation r = 0.165, P = 0.031, r = 0.237, P = 0.022 and r = 0.195, P = 0.011, respectively). Conclusion This study demonstrates that low serum sodium is associated with protein energy wasting and increased interdialytic weight gain in HD patients.

Abstract
BACKGROUND Little is known about risk factors for sudden cardiac death in hemodialysis patients during the high-risk first year of dialysis. We therefore undertook to identify such risk factors in a nationally representative cohort and were able to include baseline levels of blood fatty acids, some of which influence arrhythmogenicity and sudden cardiac death risk. DESIGN The study cohort included 100 patients who died of sudden cardiac death during the first year of hemodialysis and 300 frequency-matched controls. Using the elastic net statistical method, numerous demographic and clinical characteristics were included with baseline total serum levels for 11 major fatty acids (model 1) and with serum phospholipid fractions of these same fatty acids (model 2). Final models included only covariates that had a non-zero coefficient. RESULTS In model 1, serum albumin [odds ratio (95% CI): 0.55 (0.33-0.93); p = 0.03] and total serum long-chain n-3 docosapentaenoic acid [0.70 (0.51-0.97); p = 0.03] were inversely associated with the odds of sudden cardiac death, while the total serum saturated fatty acid level had a direct association [1.01 (1.00-1.02); p = 0.03]. In model 2, serum albumin and docosapentaenoic acid remained inversely associated with sudden cardiac death in a similar manner as in model 1. Pulse pressure also had an inverse association [0.96 (0.93-1.00); p < 0.05]. CONCLUSIONS Several factors, including blood content of docosapentaenoic acid and saturated fatty acids, were associated with the odds of sudden cardiac death during year one of hemodialysis. These results raise the possibility that dietary modification may reduce sudden death risk.

Abstract
Hyperlipidemia may lead to endothelial injury, due to its effects on homocysteine and vascular endothelial growth factor in the serum, and the mRNA expression levels of peroxisome proliferator-activated receptor-γ (PPARγ), and caspase-3 and -8 in the vascular wall. In order to prevent and mitigate the high-fat state that results from endothelial injury, this study examined the effect of folic acid (FA) and vitamin B12 (VB12) on the expression of PPARγ and caspase-3 and -8 mRNA in the abdominal aortas of rats with hyperlipidemia. Sixty 4-week-old healthy male Sprague Dawley rats were randomly divided into five groups (each n=12): the normal control (NC), high-fat diet (HL), FA, VB12 and FA+VB12 groups. Following one week of adaptive feeding, the FA, VB12 and FA+VB12 groups were subject to the intraperitoneal injection of FA (0.5 mg/day), VB12 (0.05 mg/day) and FA+VB12 (0.5 mg/day and 0.05 mg/day), respectively, while fed a high-fat diet. The rats in the NC group were injected intraperitoneally with 0.9% NaCl solution (0.5 ml/day) and fed a normal diet, whereas those in the HL group were fed a high-fat diet only. A reverse transcription-polymerase chain reaction (RT-PCR) assay demonstrated that at the end of week 12, the FA treatment had effectively increased the PPARγ mRNA level, while reducing the caspase-3 and -8 mRNA levels, compared with the high-fat diet treatment (P<0.05). The effect of FA on the expression of PPARγ and caspase-3 and -8 was enhanced when used in combination with VB12 (P<0.05). These results revealed that the application of FA, alone or in combination with VB12, improves and mitigates the high-fat state that results from endothelial injury.

Abstract
Background Resistance to ESAs (erythropoietin stimulating agents) is highly prevalent in hemodialysis patients with diabetes and associated with an increased mortality. The aim of this study was to identify predictors for ESA resistance and to develop a prediction model for the risk stratification in these patients. Methods A post-hoc analysis was conducted of the 4D study, including 1015 patients with type 2 diabetes undergoing hemodialysis. Determinants of ESA resistance were identified by univariate logistic regression analyses. Subsequently, multivariate models were performed with stepwise inclusion of significant predictors from clinical parameters, routine laboratory and specific biomarkers. Results In the model restricted to clinical parameters, male sex, shorter dialysis vintage, lower BMI, history of CHF, use of ACE-inhibitors and a higher heart rate were identified as independent predictors of ESA resistance. In regard to routine laboratory markers, lower albumin, lower iron saturation, higher creatinine and higher potassium levels were independently associated with ESA resistance. With respect to specific biomarkers, higher ADMA and CRP levels as well as lower Osteocalcin levels were predictors of ESA resistance. Conclusions Easily obtainable clinical parameters and routine laboratory parameters can predict ESA resistance in diabetic hemodialysis patients with good discrimination. Specific biomarkers did not meaningfully further improve the risk prediction of ESA resistance. Routinely assessed data can be used in clinical practice to stratify patients according to the risk of ESA resistance, which may help to assign appropriate treatment strategies. Clinical trial registration The study was registered at the German medical authority (BfArM; registration number 401 3206). The sponsor protocol ID and clinical trial unique identified number was CT-981-423-239. The results of the study are published and available at http://www.ncbi.nlm.nih.gov/pubmed/16034009.

Abstract
Several cardiovascular (CV) risk factors may explain the high rate of CV death among patients with chronic kidney disease (CKD). Among them both traditional and uremia-related risk factors are implicated and, moreover, the presence of kidney disease represents “per se” a multiplier of CV risk. Plasma lipid and lipoprotein profiles are changed in quantitative, but above all in qualitative, structural, and functional ways, and lipoprotein metabolism is influenced by the progressive loss of renal function. Statin therapy significantly reduces cholesterol synthesis and both CV morbidity and mortality either directly, by reducing the lipid profile, or via pleiotropic effects; it is supposed to be able to reduce both the progression of CKD and also proteinuria. These observations derive from a post-hoc analysis of large trials conducted in the general population, but not in CKD patients. However, the recently published SHARP trial, including over 9200 patients, either on dialysis or pre-dialysis, showed that simvastatin plus ezetimibe, compared with placebo, was associated with a significant low-density lipoprotein cholesterol reduction and a 17% reduction in major atherosclerotic events. However, no benefit was observed in overall survival nor in preserving renal function in patients treated. These recent data reinforce the conviction among nephrologists to consider their patients at high CV risk and that lipid lowering drugs such as statins may represent an important tool in reducing atheromatous coronary disease which, however, represents only a third of CV deaths in patients with CKD. Therefore, statins have no protective effect among the remaining two-thirds of patients who suffer from sudden cardiac death due to arrhythmia or heart failure, prevalent among CKD patients. The safety of statins is demonstrated in CKD by several trials and recently confirmed by the largest SHARP trial, in terms of no increase in cancer incidence, muscle pain, creatine kinase levels, severe rhabdomyolysis, hepatitis, gallstones and pancreatitis; thus confirming the handiness of statins in CKD patients. Here we will review the latest data available concerning the effectiveness and safety of statin therapy in CKD patients.

Abstract
BACKGROUND Apolipoprotein A-IV (apoA-IV) is an anti-atherogenic and anti-oxidative plasma glycoprotein involved in reverse cholesterol transport. The aim of this study was to examine the association between apoA-IV and all-cause mortality, cardiovascular endpoints and parameters of protein-energy wasting and nutrition in haemodialysis patients. METHODS This post hoc analysis was performed in the German Diabetes Dialysis Study (4D Study) evaluating atorvastatin in 1255 haemodialysis patients with type 2 diabetes mellitus, followed for a median of 4 years. The association between apoA-IV and relevant outcomes was analysed using Cox proportional hazards regression analyses. Body mass index (BMI) was used as a marker of protein-energy wasting. In addition, a definition of extended wasting was applied, combining median values of BMI, serum albumin, creatinine and sensitive C-reactive protein, to classify patients. RESULTS Mean (±SD) apoA-IV concentration was 49.8 ± 14.2 mg dL(-1). Age- and gender-adjusted apoA-IV concentrations were strongly associated with the presence of congestive heart failure at baseline [odds ratio = 0.81, 95% confidence interval (CI) 0.74-0.88 per 10 mg dL(-1) increase; P < 0.001). During the prospective follow-up, the strongest association was found for all-cause mortality [hazard ratio (HR) = 0.89, 95% CI 0.85-0.95, P = 0.001), which was mainly because of patients with BMI > 23 kg m(-2) (HR = 0.87, 95% CI 0.82-0.94, P < 0.001) and those in the nonwasting group according to the extended definition (HR = 0.89, 95% CI 0.84-0.96, P = 0.001). This association remained significant after additionally adjusting for parameters associated with apoA-IV at baseline. Further associations were observed for sudden cardiac death. ApoA-IV was less strongly associated with atherogenic events such as myocardial infarction. CONCLUSIONS Low apoA-IV levels seem to be a risk predictor of all-cause mortality and sudden cardiac death. This association might be modified by nutritional status.
