Chronic kidney disease (CKD) has been shown to be an independent risk factor for cardiovascular events. In addition, patients with pre-dialysis CKD appear to be more likely to die of heart disease than of kidney disease. CKD accelerates coronary artery atherosclerosis by several mechanisms, notably hypertension and dyslipidemia, both of which are known risk factors for coronary artery disease. In addition, CKD alters calcium and phosphorus homeostasis, resulting in hypercalcemia and vascular calcification, including the coronary arteries. Mortality of patients on long-term dialysis therapy is high, with age-adjusted mortality rates of about 25% annually. Because the majority of deaths are caused by cardiovascular disease, routine cardiac catheterization of new dialysis patients was proposed as a means of improving the identification and treatment of high-risk patients. However, clinicians may be uncomfortable exposing asymptomatic patients to such invasive procedures like cardiac catheterization, thus noninvasive cardiac risk stratification was investigated widely as a more palatable alternative to routine diagnostic catheterization. The effective management of coronary artery disease is of paramount importance in uremic patients. The applicability of diagnostic, preventive, and treatment modalities developed in nonuremic populations to patients with kidney failure cannot necessarily be extrapolated from clinical studies in non-kidney failure populations. Noninvasive diagnostic testing in uremic patients is less accurate than in nonuremic populations. Initial data suggest that dobutamine echocardiography may be the preferred diagnostic method. PCI with stenting is a less favorable alternative to CABG, however, it has a faster recovery time, reduced invasiveness, and no overall mortality difference in nondiabetic and non-CKD patients compared with CABG. CABG is associated with reduced repeat revascularizations, greater relief of angina, and increased long term survival. However, CABG is associated with a higher incidence of post-operative risks. The treatment chosen for each patient should be an individualized decision based upon numerous risk factors. CKD is associated with higher rates of CAD, with 44% of all-cause mortality attributable to cardiac disease and about 20% from acute MI. Optimal treatment including aggressive lifestyle modifications and concomitant medical therapy should be implemented in all patients to maximize benefits from either PCI or CABG. Future prospective randomized controlled trials with newer second or third generation DES and bioabsorbable DES are necessary to determine if PCI may be non-inferior to CABG in the future.

Niacin is the oldest drug available for the treatment of dyslipidemia. It has been studied extensively and tested in clinical trials of atherosclerotic cardiovascular disease prevention and regression in the general population, but not specifically in patients with chronic kidney disease (CKD), who are at extremely high residual risk despite current therapy. Despite the current controversy about recent trials with niacin, including their limitations, there may be a place for this agent in select patients with CKD with dyslipidemia. Niacin has a favorable unique impact on factors affecting the rate of glomerular filtration rate decline, including high-density lipoprotein (HDL) particle number and function, triglyceride levels, oxidant stress, inflammation and endothelial function, and lowering of serum phosphorus levels by reducing dietary phosphorus absorption in the gastrointestinal tract. These effects may slow glomerular filtration rate decline and ultimately improve CKD outcomes and prevent cardiovascular risk. This review presents the clinically relevant concept that niacin holds significant potential as a renoprotective therapeutic agent. In addition, this review concludes that clinical investigations to assess the effect of niacin (in addition to aggressive low-density lipoprotein cholesterol lowering) on reduction of cardiovascular events in patients with CKD with very low HDL cholesterol (or those with identified dysfunctional HDL) and elevated triglyceride levels need to be considered seriously to address the high residual risk in this population.

In patients suffering from urolithiasis, metabolic diagnostics often reveals abnormalities contributing to the formation of stones: hypocitraturia, hyper- and hypocalcemia, hypercalciuria, hypomagnesemia/hypomagnesuria, hyperoxalaturia, etc. Before surgery, complex biochemical examination of blood and 24-hourcollection urine in 82 patients with urolithiasis was performed. The analysis of the main laboratory parameters of carbohydrate, lipid, calcium and phosphorus and purine metabolism found the prevalence of violations of calcium and phosphorus metabolism in these patients. Dyslipidemia was diagnosed in 31 (37.8%) patients. There was a significant positive correlation between serum total cholesterol and serum total calcium (rs = 0.3315, P = 0.0103). Low serum calcium levels were associated with hyperoxalaturia (rs = -0.4270, P = 0.0295). There was a significant effect of natriuria on urinary excretion of oxalate (rs = 0.6107, P = 0.0001), Mg (rs = 0.4156, P = 0.0096) and K (rs = 0.5234, P = 0.00005). The study shows the role of magnesium in the prevention of recurrence and manifestation of urolithiasis. The combination of two or more types of hormonal and metabolic disorders increases the incidence of recurrent stones. Timely correction of hormonal-metabolic status allows to reduce the risk of stone formation, and hospitalization attributable to the complications associated.

Ischemic nephropathy is an emerging cause of end stage renal disease, associated with many co-morbidities especially cardiovascular disease risk and derangement in calcium-phosphorus homeostasis resulting in hyperphosphatemia, influencing bones, a characteristic of advancing chronic kidney disease. The management of elevated serum phosphorus has been a challenge in this patient population with compromised kidney performance, as available phosphorus lowering agents possess many undesirable hazardous secondary effects and/or are very expensive. While niacin in different formulation is known to not only correct dyslipidemia but also reduce phosphorus level, but its clinical use restricted owing to side effects. The objective of present study is to evaluate such effect of niacin extended release (NER) in ischemic nephropathy. The chronic kidney disease patients fulfilling the pre-defined criteria were randomly categorized into two groups of equal size (n=60) and prescribed either atorvastatin 20 mg/day or NER 500 mg/day with the same dose of statin for four months. A control of 50 healthy characters matched was also incorporated for local reference range. Baseline and follow up phosphorus concentration was measured and means were compared using t-test at SPSS version 17 with 0.05 chosen alpha. There was no difference in the baseline levels in both groups while significant (p<0.001) hyperphosphatemia was observed in both units as compared with healthy controls. The administration of atorvastatin alone for four weeks showed an insignificant decrease in phosphorus, whereas, NER significantly reduced phosphorus (p<0.001). The mean percent change from baseline to follow up further endorsed the finding as statin alone brought -13.8 % reduction in phosphorus and NER -47 % from baseline. NER, at its lowest prescribed dose once a day was well tolerated by most of the patients and demonstrated significant goal achievement of phosphorus reduction. It is concluded that NER even at low doses in renal compromised dyslipidemic patients may be a promising approach to prevent the harmful vascular, valvular effects caused by hyperphosphatemia in addition to its principal target of HDL-C elevation.

With the population aging and declining incidence of rheumatic heart disease, calcific aortic valve disease (CAVD) has become the most frequent valve disease and the common cause of aortic valve replacement. Patients with CAVD need to cope with a deteriorating quality of life and valve replacement is the only effective clinical option for the patients. Therefore, early pharmacotherapy is of great significance in prevention or slow-down of the progression of CAVD. For years CAVD was considered to be a passive wear and tear process of valves, but now it is recognized as an active and multi-factorial process. Histopathologic studies have revealed that inflammation, disorder of calcium and phosphorus metabolism and dyslipidemia are involved in the process of CAVD. Clinical trials of CAVD pharmacotherapy have been carried out based on those histopathologic studies. Statin, renin-angiotensin inhibitors and anti-osteoporosis drug are well studied in recent years. This article reviews the recent research progress of the pharmacotherapy for CAVD.

Patients with chronic kidney disease (CKD) are often instructed to adhere to a renal-specific diet depending on the severity and stage of their kidney disease. The prescribed diet may limit certain nutrients, such as phosphorus and potassium, or encourage the consumption of others, such as high biological value (HBV) proteins. Eggs are an inexpensive, easily available and high-quality source of protein, as well as a rich source of leucine, an essential amino acid that plays a role in muscle protein synthesis. However, egg yolk is a concentrated source of both phosphorus and the trimethylamine N-oxide precursor, choline, both of which may have potentially harmful effects in CKD. The yolk is also an abundant source of cholesterol which has been extensively studied for its effects on lipoprotein cholesterol and the risk of cardiovascular disease. Efforts to reduce dietary cholesterol to manage dyslipidemia in dialysis patients (already following a renal diet) have not been shown to offer additional benefit. There is a paucity of data regarding the impact of egg consumption on lipid profiles of CKD patients. Additionally, egg consumption has not been associated with the risk of developing CKD based on epidemiological studies. The egg yolk also contains bioactive compounds, including lutein, zeaxanthin, and vitamin D, which may confer health benefits in CKD patients. Here we review research on egg intake and CKD, discuss both potential contraindications and favorable effects of egg consumption, and describe the need for further research examining egg intake and outcomes in the CKD and end-stage renal disease population.
