This article describes the relationship between CVD and CKD, the current state of knowledge regarding medical interventions, and underscores the importance of attending to both CVD and kidney disease aspects in each individual. The burden of cardiac disease in CKD patients is high with severe LVH, dilated cardiomyopathy and coronary artery disease occurring frequently. This predisposes to congestive heart failure, angina, myocardial infarction, and death. Multiple risk factors for cardiac disease exist and include hypertension, diabetes, smoking, anemia, abnormal calcium and phosphate metabolism, inflammation, and LVH. The efficacy of risk factor intervention has not been established in these populations, although there is good evidence for good blood pressure control, partial correction of anemia, treatment of dyslipidemia, cessation of tobacco use, correction of divalent abnormalities, and aspirin us. Appropriate use of ACE inhibitors, beta-blockers, and statins should be encouraged.

An increasing number of patients are developing chronic kidney disease (CKD). Appropriate care for patients with CKD must occur in the earliest stages, preferably before CKD progresses to more severe stages. Therefore, recognition and treatment of CKD and its associated complications must occur in primary care settings. Patients with CKD often have comorbid conditions such as diabetes mellitus, hypertension, and dyslipidemia, creating specific considerations when treating these diseases. Also, these patients have CKD-related conditions, including anemia and renal osteodystrophy, that are not traditionally evaluated and monitored by the primary care practitioner. Collectively, many opportunities exist for pharmacists who practice in the primary care setting to improve the care of patients with CKD.

Cardiovascular risk is dramatically increased in patients with end-stage renal disease (ESRD). However, even minor dys-functions such as microalbuminuria or a mild increase in serum creatinine (Cr) have a major impact on cardiovascular risk. Increased cardiovascular risk is present in multiple populations, including general populations, patients with moderate risk such as hypertensives, and high-risk patients including patients with heart failure and myocardial necrosis. There are many mechanisms underpinning the increased cardiovascular risk. Regarding atherosclerosis, the kidney can be victim or villain. On the one hand, both kidney disease per se and renal insufficiency can induce vascular damage, thereby increasing cardiovascular risk. Kidney disease without renal insufficiency can cause an increased prevalence in hypertension, dyslipidemia (nephrotic syndrome), sympathetic system hyperactivity, and in renin angiotensin system hyperactivity. A moderate-severe renal insufficiency can induce an increase in many vasculotoxic substances such as ADMA, lipoprotein(a), homocysteine, disturbances in calcium and phosphate metabolism, anemia and left ventricular hypertrophy. A more severe renal insufficiency can induce the ominous malnutrition-inflammation-atherosclerosis (MIA) syndrome. On the other hand, the kidney can be the victim of atherosclerosis. Ischemic nephropathy, caused by atherosclerotic renal artery disease and atheroembolism from abdominal aorta are two examples. Finally, it is important to consider that the kidney, being an organ with a wide vasculature, could be a sophisticated sensor of subclinical cardiovascular damage.

Vitamin D3 is modified by vitamin D3-25-hydroxylase in the liver, and 25-hydroxyvitamin D3-1alpha-hydroxylase in the kidney, to form the active metabolite, 1,25-dihydroxyvitamin D3. Chronic kidney disease (CKD) is characterized by reduced synthesis of 1,25-dibydroxyvitamin D3, inadequate renal phosphate clearance and calcium imbalance, secondary hyperparathyroidism (SHPT) and bone disease. CKD patients encounter a much higher risk of cardiovascular disease (CVD) than the general public. The cardiovascular risk factors for CKD patients include conventional factors such as age, gender, hypertension, diabetes, dyslipidemia and smoking, and non-conventional factors, such as anemia, uremia, reduced vascular compliance, inflammation and various hormonal factors. Several vitamin D analogs are currently available for the treatment of SHPT, and recent clinical data show that these analogs provide survival benefit for CKD patients in the order of paricalcitol > calcitriol > no vitamin D analog, independent of parathyroid hormone and calcium. Moreover, the survival benefit seems to be associated with cardiovascular causes. The observations made from these clinical studies raised intriguing questions about the involvement of the vitamin D receptor locus (VDR) in the cardiovascular system. This review discusses recent data regarding the role of vitamin D and its analogs in the CVD associated with CKD.

Cardiovascular complications are the main cause of mortality and morbidity among patients on dialyses. The aim of the work was to assess the effect of the type of renal replacement therapy on the risk factors and cardiovascular complication in dialyzed patients. The studies were performed retrospectively on 90 hemodialyzed and 49 peritoneally dialyzed patients. Risk factors of cardiovascular diseases as well as serum lipids, complete blood count, serum albumin, fibrinogen, C-reactive protein, calcium, phosphates, PTH, systolic, diastolic, mean blood pressure, left ventricular hypertrophy. Hemodialyzed patients were more anemic, longer on renal replacement therapy, with higher albumin, phosphates, lower fibrinogen, cholesterol, LDL, triglycerides, calcium, systolic and diastolic blood pressure than peritoneally dialyzed patients. Left ventricular hypertrophy more frequently found in hemodialyzed patients than in peritoneally dialyzed patients. In peritoneally dialyzed patients glucose load into the peritoneum, dyslipidemia and hiperfibrinogenemia may further contribute at the cardiovascular complications. In hemodialyzed patients anemia, left ventricular hypertrophy and ischemic heart disease is more frequent than in peritoneally dialyzed patients.

Chronic kidney disease (CKD) is a permanent, progressive loss of kidney function characterized by a decline in glomerular filtration rate (GFR). Early identification of CKD risk factors provides an opportunity to prevent or delay the progression of kidney disease and decrease morbidity and mortality. There is increasing evidence to suggest that the adverse outcomes of CKD can be delayed or prevented by early detection and treatment. Current literature suggests that a low-protein, low-phosphorus diet may retard the progression of kidney disease. Other modifiable risk factors affecting CKD include proteinuria, hypertension, hyperglycemia, dyslipidemia, bone disease, anemia, and obesity. This discussion will review the current clinical nutrition guidelines for managing adult patients with CKD.

Cardiovascular disease is one of the most important causes of morbidity and mortality in children with end-stage renal failure. Chronic inflammation and malnutrition have been suggested to be risk factors for cardiovascular disease. However, to date, biomarkers of inflammation have not been well studied in children. The aim of this study was to investigate the relation between chronic inflammation and cardiovascular risk factors in children on hemodialysis therapy. Twenty-seven patients on hemodialysis (14 girls, 13 boys) of mean age 15.3 +/- 2.4 years and 20 healthy children (13 girls, 7 boys) of mean age 14.3 +/- 2.7 years were included the study. C-reactive protein (CRP), albumin, prealbumin, transferrin, ferritin, and fibrinogen were measured as the markers of inflammation. The levels of CRP, ferritin, and erythrocyte sedimentation rate among hemodialysis patients were significantly higher than those of control subjects (P < .001 for all). Albumin and transferrin levels were found to be lower than those of control group (P = .02 and P < .001, respectively). CRP levels were negatively correlated with albumin, prealbumin, apoprotein A1, HDL, and hemoglobin levels, and positively correlated with erythropoietin/Htc ratios. This study suggests that hemodialyzed children are exposed to chronic inflammation. In addition, CRP may be an indicator of chronic inflammation related to cardiovascular risk factors, such as malnutrition, dyslipidemia, and anemia. In conclusion, we suggest that the risk of cardiovascular disease could be reduced by defining markers of chronic inflammation and malnutrition in hemodialyzed children and by taking necessary measures at an early stage.

Cardiac artery disease and heart failure are major causes for morbidity and mortality in diabetes in general and in those with chronic kidney disease (CKD) in particular. Hypertension and dyslipidemia are more common in diabetes and the prevalence of coronary artery disease in diabetics is two-fold to four-fold higher than in nondiabetics. In those with CKD the incidence of cardiovascular complications is nearly two-fold higher than those without CKD. Recent studies suggest that the pathophysiology of cardiac disease is complex process involving both microvascular and macrovascular disease. In addition, myocardial lipotoxicity may be a novel contributing factor particularly in type 2 diabetics. Compelling evidence from cardiovascular outcomes trials indicates that treatment with drugs that block the renin-angiotensin system are cardioprotective in diabetics with microalbuminuria and early stages of kidney disease. Multiple risk factor intervention aimed at optimal blood pressure control (BP <130/<80 mmHG), lowering LDL cholesterol below 100 mg/dl, lowering triglyceride level to 150 mg/dl, A1C <6.5%, treatment with an ACE inhibitor or an angiotensin II receptor blocker, administration of once daily low-dose aspirin and smoking cessation together reduce cardiovascular morbidity and mortality in type 2 diabetics. Novel studies including diabetics with nephropathy aimed at improving outcomes in diabetics by treatment of anemia and optimal control of dyslipidemia are now underway. These and other clinical trials should provide important new insights into improving the quality of life in diabetics and ultimately preventing cardiac disease.

Sirolimus (SRL) is a new immunosuppressive drug approved for renal transplantation, but is being used increasingly in orthotopic liver transplantation (OLT). Compared with the calcineurin inhibitors, SRL has different mechanisms of action and side effects profile. Thus, this drug offers significant potential advantages over other immunosuppressive agents. SRL does not cause glucose intolerance, hypertension or renal failure, but it may cause dyslipidemia, hepatic artery thrombosis, thrombocytopenia, anemia, leukopenia, oral mucosa ulcers, edema, arthralgias and wound complications. SRL inhibits the signal of interleukin 2 at a post-receptor level, inhibiting lymphocyte proliferation and fibroblast proliferation. It also has antineoplastic and antifungal effects. We report a 10 years old girl who underwent OLT, experiencing a biopsy-proven recurrent acute rejection (AR) in spite of using three immunosuppressive agents (tacrolimus, mofetil micofenolate and steroids). She developed diabetes mellitus as a consequence of the immunosuppressive therapy. She was rescued with SRL, not experiencing AR again. Mofetil micofenolate, steroids and insulin could be discontinued and tacrolimus doses were reduced, without experiencing severe complications. SRL is a new and safe immunosuppressive agent for rescue in patients with OLT and recurrent AR.

The current implementation into nephrology clinical practice of guidelines on treatment of cardiovascular (CV) risk factors in chronic kidney disease (CKD) is unknown. We designed a cross-sectional analysis to evaluate the prevalence and treatment of eight modifiable CV risk factors in 1058 predialysis CKD patients (stage 3: n=486; stage 4: n=430, stage 5: n=142) followed for at least 1 year in 26 Italian renal clinics. The median nephrology follow-up was 37 months (range: 12-391 months). From stages 3 to 5, hypertension was the main complication (89, 87, and 87%), whereas smoking, high calcium-phosphate product and malnutrition were uncommon. The prevalence of proteinuria (25, 38, and 58%), anemia (16, 32, and 51%) and left ventricular hypertrophy (51, 55, and 64%) significantly increased, while hypercholesterolemia was less frequent in stage 5 (49%) than in stages 4 and 3 (59%). The vast majority of patients received multidrug antihypertensive therapy including inhibitors of renin-angiotensin system; conversely, diuretic treatment was consistently inadequate for both frequency and dose despite scarce implementation of low salt diet (19%). Statins were not prescribed in most hypercholesterolemics (78%), and epoietin treatment was largely overlooked in anemics (78%). The adjusted risk for having a higher number of uncontrolled risk factors rose in the presence of diabetes (odds ratio 1.29, 95% confidence interval 1.00-1.66), history of CV disease (odds ratio 1.48, 95% confidence interval 1.15-1.90) and CKD stages 4 and 5 (odds ratio 1.75, 95% confidence interval 1.37-2.22 and odds ratio 2.85, 95% confidence interval 2.01-4.04, respectively). In the tertiary care of CKD, treatment of hypertension is largely inadequate, whereas therapy of anemia and dyslipidemia is frequently omitted. The risk of not achieving therapeutic targets is higher in patients with diabetes, CV disease and more advanced CKD.
