The Kidney Disease: Improving Global Outcomes (KDIGO) organization developed a clinical practice guideline in 2013 on lipid management and treatment of all adults and children with chronic kidney ...disease (CKD). All forms of CKD are included (non-dialysis-dependent, dialysis-dependent, and kidney transplant recipients).
The KDIGO Lipid Guideline Development Work Group defined the scope of the guideline, gathered evidence, determined topics for systematic review, and graded the quality of evidence that had been summarized by an evidence review team. Searches of the English-language literature were conducted through August 2011 and supplemented by targeted searches through June 2013. Final modification of the guidelines was informed by the KDIGO Board of Directors and a public review process involving registered stakeholders.
The full guideline includes 13 recommendations; a key element was the recommendation for statin or statin with ezetimibe treatment of adults aged 50 years or older with estimated glomerular filtration rates less than 60 mL/min/1.73 m2 but not treated with long-term dialysis or kidney transplantation. This synopsis focuses on 8 recommendations pertinent to assessment of lipid status and treatment with a statin-based regimen in adults.

The Kidney Disease: Improving Global Outcomes (KDIGO) organization developed clinical practice guidelines on lipid management for all adults and children with chronic kidney disease (CKD). Thirteen ...recommendations were obtained from the available evidence outlining a three-step management including assessment in all, treatment in many, and follow-up measurements in few. A key element is the recommendation of statin or statin/ezetimibe treatment in adults aged ≥50 years with estimated glomerular filtration rate (eGFR) <60ml/min per 1.73m2 but not treated with chronic dialysis or kidney transplantation. In dialysis patients, the magnitude of any relative reduction in risk appears to be substantially smaller than in earlier stages of CKD and initiation of statin treatment is not recommended for most prevalent hemodialysis patients. In the past, clinical practice guidelines suggested the use of targets for LDL cholesterol, which require repeated measurements. Treatment escalation with higher doses of statin would be a consequence when LDL cholesterol targets are not met. The KDIGO Work Group did not recommend this strategy because higher doses of statins have not been proven to be safe in the setting of CKD. Since LDL cholesterol levels do not necessarily suggest the need to increase statin doses, follow-up measurement of lipid levels is not recommended.
Individuals with diabetes mellitus exhibit an increased propensity to develop cardiovascular disorders such as coronary artery disease, stroke and heart failure. Over recent decades, numerous ...cardiovascular outcome trials in individuals with type 2 diabetes have been published, with data showing a reduction of cardiovascular morbidity and mortality by sodium–glucose cotransporter 2 (SGLT2) inhibitors. These results not only provide novel therapeutic options for this high-risk population but also advance our current understanding of cardiovascular risk reduction in diabetes. The current overview article summarises these aspects and discusses future treatment strategies with SGLT2 inhibitors in diabetic and non-diabetic individuals with chronic kidney disease, liver disease and heart failure.

Summary The heart and the vascular tree undergo major structural and functional changes when kidney function declines and renal replacement therapy is required. The many cardiovascular risk factors ...and adaptive changes the heart undergoes include left ventricular hypertrophy and dilatation with concomitant systolic and diastolic dysfunction. Myocardial fibrosis is the consequence of impaired angio-adaptation, reduced capillary angiogenesis, myocyte-capillary mismatch, and myocardial micro-arteriopathy. The vascular tree can be affected by both atherosclerosis and arteriosclerosis with both lipid rich plaques and abundant media calcification. Development of cardiac and vascular disease is rapid, especially in young patients, and the phenotype resembles all aspects of an accelerated ageing process and latent cardiac failure. The major cause of left ventricular hypertrophy and failure and the most common problem directly affecting myocardial function is fluid overload and, usually, hypertension. In situations of stress, such as intradialytic hypotension and hypoxaemia, the hearts of these patients are more vulnerable to developing cardiac arrest, especially when such episodes occur frequently. As a result, cardiac and vascular mortality are several times higher in dialysis patients than in the general population. Trials investigating one pharmacological intervention (eg, statins) have shown limitations. Pragmatic designs for large trials on cardio-active interventions are mandatory for adequate cardioprotective renal replacement therapy.
Sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce the risk of hospitalization for heart failure in patients regardless of the presence or absence of diabetes. More evidence is needed regarding ...the effects of these drugs in patients across the broad spectrum of heart failure, including those with a markedly reduced ejection fraction.
In this double-blind trial, we randomly assigned 3730 patients with class II, III, or IV heart failure and an ejection fraction of 40% or less to receive empagliflozin (10 mg once daily) or placebo, in addition to recommended therapy. The primary outcome was a composite of cardiovascular death or hospitalization for worsening heart failure.
During a median of 16 months, a primary outcome event occurred in 361 of 1863 patients (19.4%) in the empagliflozin group and in 462 of 1867 patients (24.7%) in the placebo group (hazard ratio for cardiovascular death or hospitalization for heart failure, 0.75; 95% confidence interval CI, 0.65 to 0.86; P<0.001). The effect of empagliflozin on the primary outcome was consistent in patients regardless of the presence or absence of diabetes. The total number of hospitalizations for heart failure was lower in the empagliflozin group than in the placebo group (hazard ratio, 0.70; 95% CI, 0.58 to 0.85; P<0.001). The annual rate of decline in the estimated glomerular filtration rate was slower in the empagliflozin group than in the placebo group (-0.55 vs. -2.28 ml per minute per 1.73 m
of body-surface area per year, P<0.001), and empagliflozin-treated patients had a lower risk of serious renal outcomes. Uncomplicated genital tract infection was reported more frequently with empagliflozin.
Among patients receiving recommended therapy for heart failure, those in the empagliflozin group had a lower risk of cardiovascular death or hospitalization for heart failure than those in the placebo group, regardless of the presence or absence of diabetes.

In the BI 10773 (Empagliflozin) Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME) trial involving 7,020 patients with type 2 diabetes and established ...cardiovascular (CV) disease, empagliflozin given in addition to standard of care reduced the risk of CV death by 38% versus placebo (hazard ratio HR 0.62 95% CI 0.49, 0.77). This exploratory mediation analysis assesses the extent to which treatment group differences in covariates during the trial contributed to CV death risk reduction with empagliflozin.
Effects of potential mediators, identified post hoc, on the HR for CV death with empagliflozin versus placebo were analyzed by Cox regression models, with treatment group adjusted for the baseline value of the variable and its change from baseline or updated mean (i.e., considering all prior values), each as a time-dependent covariate. HRs were compared with a model without adjustment for covariates. Multivariable analyses also were performed.
Changes in hematocrit and hemoglobin mediated 51.8% and 48.9%, respectively, of the effect of empagliflozin versus placebo on the risk of CV death on the basis of changes from baseline, with similar results in analyses on the basis of updated means. Smaller mediation effects (maximum 29.3%) were observed for uric acid, fasting plasma glucose, and HbA
. In multivariable models, which incorporated effects of empagliflozin on hematocrit, fasting glucose, uric acid, and urine albumin:creatinine ratio, the combined changes from baseline provided 85.2% mediation, whereas updated mean analyses provided 94.6% mediation of the effect of empagliflozin on CV death.
In this exploratory analysis from the EMPA-REG OUTCOME trial, changes in markers of plasma volume were the most important mediators of the reduction in risk of CV death with empagliflozin versus placebo.
