Patients with chronic renal failure are prone to cardiovascular complications. The mechanisms and the assessment of the risk of cardiovascular diseases (CVD) in this population are of interest. The purpose of this study was to investigate the traditional and potential risk factors for the development of CVD and their contribution to ischemic heart disease (IHD) and variation in carotid intima media thickness (IMT) in hemodialyzed patients (HD). Twenty-one chronically HD patients and nineteen healthy volunteers were recruited. Studied parameters were intima-media thickness, body mass index (BMI), mean arterial blood pressure (MAP), hemoglobin, fibrinogen (Fbg), serum lipids, lipoprotein (a) [Lp(a)], total homocysteine (tHcy). Mean carotid IMT, tHcy, Fbg and Lp(a) were higher in HD patients compared to the control group. There were no differences in cholesterol (tCh) and triglycerides between these groups. Patients with ischemic heart disease were older and they had higher values of carotid IMT, tCh, triglycerides, Fbg and Lp(a). There were no differences in MAP, time on dialysis and tHcy between the two subgroups (with vs without IHD). Carotid IMT correlated positively with age (r = 0.68, p = 0.001), BMI (r = 0.50, p = 0.02), tCh (r = 0.58, p < 0.01), LDL- cholesterol (r = 0.55, p = 0.01) and Fbg (r = 0.57, p < 0.01) but not with tHcy or Lp(a) in the patients group. Carotid intima media thickness thus reflects the risk for ischemic heart disease in hemodialyzed patients. Elevated fibrinogen concentration and dyslipidemia influence arterial remodelling.

Pulse wave velocity (PWV) is known to represent arterial stiffness and is established as a marker for cardiovascular risk and a prognostic factor for mortality in the case of chronic renal failure or hypertension. The application of an automated apparatus for measuring brachial-ankle pulse wave velocity (baPWV) has made PWV measurement non-invasive, easier to screen for cardiovascular risk and as a result, baPWV measurements have become widely applied in clinical practice in recent years. We assessed the baPWV in 7 flank hypothyroidism patients and 28 subclinical hypothyroidism patients. In comparison with age matched healthy controls, 3 hypothyroid patients had advanced values and by replacement therapy, all 7 subjects showed improvement in their baPWV values (1531.2 +/- 242.7 to 1330.2 +/- 208.6 cm/s, p<0.05). In 28 subclinical hypothyroid subjects, 71% also had accelerated baPWV values for their age. Ten subjects (36% of all) had neither hypertension, hyperlipidemia, diabetes nor were taking any medication, and yet 8 patients out of 10 showed advanced baPWV values compared to age matched mean values. The baPWV was not correlated to TSH or total cholesterol levels, and was associated with only age and blood pressure (p = 0.01, <0.001, respectively), which are widely demonstrated as the characteristics for baPWV. In two subclinical hypothyroid subjects, who were normotensive and had no dyslipidemia, thyroxine treatment was performed and the baPWV decreased with unchanged blood pressure and total cholesterol levels. We concluded that the arterial wall stiffness tends to be increased in both overt and subclinical hypothyroid patients, and an appropriate treatment could reverse the abnormalities. It is possible that the initiation of adequate treatment in subclinical hypothyroidism may reduce the cardiovascular risk.

The aim of the study was to analyze the etiology, the factors for progression of chronic renal failure to end-stage-renal disease (ESRD), and the influence of ESRD on the survival rate among a cohort of 59 heart transplant patients (HTP) referred for the management of chronic renal failure (CRF). At the time of the first nephrology consultation (6 +/- 4.25 years after cardiac transplantation) the mean creatininemia was 261.5 +/- 99 micromol/L and mean creatinine clearance (Cockcroft formula) was 32 +/- 15 mL/min. The cause of CRF were calcineurin inhibitor toxicity in 38.9% of patients, vascular events in 15.2%, hemolytic uremic syndrome in 5%, membranous glomerulopathy in 3.3%, diabetes in two patients, focal/segmental glomerulosclerosis in 3.3%, renal hypoplasia in 1.7%, and unknown in 27%. Evolution to ESRD occurred in 38.9% of patients: 17 patients started hemodialysis, three peritoneal dialysis, and two received a preemptive kidney transplantation. Creatininemia (micromol/L) at the time of nephrology referral was 229.2 +/- 72.6 versus 315.8 +/- 113.4 (P < .001) and creatinine clearance (mL/min) was 34.9 +/- 15.1 versus 27.3 +/- 13.7 (P = .049) for patients with CRF versus ESRD, respectively. Both proteinuria (g/24 hours) of 1 +/- 2.2 versus 2.3 +/- 1.8 (P = .02) and tobacco use in 35.1% versus 54.4% (P = .045) were significantly associated with progression of CRF, while age at the time of heart transplantation, cause of cardiac failure and renal failure, high blood pressure, type 2 diabetes, dyslipidemia, alcoholism, cirrhosis, and cerebral vascular accident were not. Death occurred in 18 HTP: 50% of patients with ESRD and 18.5% of patients with CRF-a 2.6 relative risk of of death in HTP patients with ESRD compared with HTP with CRF only (P < .01).

Type 2 diabetes is reaching epidemic proportions throughout the world, representing the most common cause of ESRD. Early identification of renal impairment associated with diabetes and initiation of renoprotective therapy are imperative. High BP, dyslipidemia, long duration of diabetes, and poor glycemic control are important risk factors; their modification, renal function monitoring, and combined therapies are the current integrated approaches to treat patients with diabetic kidney disease. Strong evidence suggests that achieving target BP goals via inhibition of the renin-angiotensin-aldosterone system confers significant renal protection for diabetic patients. Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers lower BP and reduce both the progression of renal damage and adverse cardiovascular events; some important renoprotective actions seem to be independent of the antihypertensive effect. Stringent quality of glycemic control is another key point to prevent onset of nephropathy or slow its progression. Evidence from basic research and clinical trials indicates that hypolipidemic drugs, mainly statins, contribute to modulate the progression of renal damage in diabetes; their use should be considered in any patient with diabetes. Smoking cessation may slow nephropathy progression; given the additional health benefits of stopping smoking, this advice is an important part of the strategy of diabetic nephropathy treatment and prevention. In conclusion, a target-driven, long-term, intensified intervention aimed at multiple risk factors should be recommended in patients with diabetes to preserve their kidney function.

Premature atherosclerotic coronary heart disease driven by multiple risk factors is a major cause of morbidity and mortality among the 6 million patients in the United States with chronic renal failure. Consensus is that kidney failure and renal transplantation patients should be treated aggressively for dyslipidemia. Major medical literature databases were searched for published information about fluvastatin, a HMG-CoA reductase inhibitor, used in patients with impaired renal function. This article characterizes the dyslipidemia observed in these clinical settings and reviews the clinical experience with fluvastatin.

Chronic kidney disease is associated with cardiovascular event rates that are at least as high as in patients with established atherosclerotic cardiovascular disease or in those with diabetes mellitus. Chronic kidney disease is therefore considered a cardiovascular disease risk equivalent. Treatment of dyslipidemia, which is very common in this population and reflects the pattern seen in the metabolic syndrome, reduces cardiovascular events in patients with chronic kidney disease. Thus, patients with chronic kidney disease should be evaluated and treated for dyslipidemia. Dyslipidemia is a risk factor for the development of impaired kidney function. Dyslipidemia is also associated with progressive renal disease in subjects with no overt renal disease, as well as those with diabetic and nondiabetic kidney disease. Although definitive randomized controlled trials are lacking, the collective evidence suggests that treatment of dyslipidemia is associated with less decline in renal function. The use of potent statins in high doses can lead to transient proteinuria via impairment of proximal tubular receptor--mediated endocytosis, in a dose-dependent manner. Over the long term, however, the use of statins results in a reduction in proteinuria and in the rate of decline of renal function. Several large definitive trials that are currently underway to examine the safety and efficacy of statins in cardiovascular and renal protection should provide more definitive answers on the role of these drugs in this very high risk population.

Studies were carried out in 183 non-dialyzed, 123 hemodialysis, 81 continuous ambulatory peritoneal dialysis and 35 post-transplant patients and in 103 healthy subjects as a reference group. Lipids and apolipoprotein (apo)AI and apoB were determined using Roche kits. An anti-apoB antibody was used to separate apoB-containing apoCIII and apoE-triglyceride-rich lipoprotein (TRL) in the non-high-density lipoprotein (non-HDL) fraction from apoCIIInonB and apoEnonB in the HDL fraction in four groups of patients with chronic renal failure (CRF) and healthy subjects. Multivariate linear regression analysis was used to investigate the relationship between triglyceride (TG) or HDL-cholesterol (HDL-C) concentrations and lipoproteins. Dyslipidemia varied according to the degree of renal insufficiency, the type of dialysis and therapy regime in CRF patients. Lipoprotein disturbances were manifested by increased TG, non-HDL-C and TRL concentrations, and decreased HDL-C and apoAI concentrations, whereas post-renal transplant patients showed normalization of lipid and lipoprotein profiles, except for TG levels and total apoCIII and apoCIIInonB. The present study indicates that CRF patients have disturbed lipoprotein composition, and that hypertriglyceridemia and low HDL-C concentrations in these patients are multifactorial, being secondary to disturbed lipoproteins. The method using anti-apoB antibodies to separate apoB-containing lipoproteins in the non-HDL fraction from non-apoB-containing lipoproteins in HDL can be used in the diagnosis and treatment of patients with progression of renal failure or atherosclerosis. The variability of TG and HDL-C concentrations depends on the variability of TRL and cholesterol-rich lipoprotein concentrations, but the decreases in TG and increases in HDL-C concentrations are caused by apoAI concentration variability. These relationships, however, need to be confirmed in further studies.

Patients undergoing chronic renal replacement therapy have a high incidence of dyslipidemia. In general, there are increased concentrations of triglyceride-rich apolipoprotein B-containing particles. These elevations lead to increased levels of non-high-density lipoprotein (HDL) levels. This pattern is further modified by the method of dialysis (peritoneal versus hemodialysis) and comorbidities such as diabetes. End-stage renal disease patients also demonstrate increased levels of lipoprotein(a) (Lp(a)) and oxidized low-density lipoprotein (LDL)both of which are highly atherogenic. This review focuses on the pathogenesis of these lipid abnormalities and their role in the atherosclerotic process.

Chronic renal disease is accompanied by characteristic abnormalities of lipid metabolism, which appear as a consequence of nephrotic syndrome or renal insufficiency and are reflected in an altered apolipoprotein profile as well as elevated plasma lipid levels. Experimental and clinical studies have suggested a correlation between the progression of renal disease and dyslipidemia. High cholesterol and triglyceride plasma levels have been demonstrated to be independent risk factors for progression of renal disease in humans. The underlying pathophysiologic mechanisms for the relationship between lipid levels and progression of renal disease are not yet fully understood, although there are data that oxidative stress and insulin resistance may mediate the lipid-induced renal damage. In the animal model, lipid-lowering agents seem to ameliorate glomerular damage, preventing glomerulosclerosis and interstitial fibrosis. Although evidence from clinical studies indicates that statin therapy is associated with significant benefit in individuals with established chronic renal failure, whether lipid reduction can slow the renal functional decline awaits a primary renal outcome lipid-lowering therapy study.

Recovery of the patients after transplantation of non-renal organs may be complicated by multi-faceted chronic renal failure (CKD) which is regarded as an independent risk factor of graft dysfunction and mortality. The occurrence of CKD in non-renal transplant recipients depends mainly on a type of transplanted organ, immunosuppressive protocol and pre-transplant kidney dysfunction. Several concomitant diseases including arterial hypertension, dyslipidemia, diabetes mellitus, hepatitis or perioperative renal injury may contribute to chronic kidney disease. Current data suggest that a problem of kidney insufficiency in non-renal organ transplant recipients may still be underscored. Clinicians ought be aware that renal dysfunction should be added to a list of major post-transplant complications.
