Dyslipidemias are common in patients with chronic kidney disease. The causes vary with the stage of kidney disease, the degree of proteinuria, and the modality of end-stage renal disease treatment. Dyslipidemias have been associated with kidney disease progression, and a number of small, randomized, controlled trials of lipid-lowering agents have been conducted. Unfortunately, the results of these trials, although encouraging, have been inconclusive because of the small numbers of patients enrolled. Dyslipidemias may also contribute to the high incidence of cardiovascular disease in patients with chronic kidney disease. This is most likely for patients with chronic renal insufficiency and for kidney transplant recipients. Less certain is the role of dyslipidemias in the pathogenesis of cardiovascular disease among dialysis patients.

Proteinuria in the general population has been shown to be associated with cardiovascular disease, which is the main cause of death in renal transplantation. We investigated the effect of proteinuria on cardiovascular disease after renal transplantation in 532 renal transplant patients with functioning grafts for more than 1 year. Patients were classified into two groups depending on the presence of persistent proteinuria. We analyzed graft and patient survival, posttransplantation cardiovascular disease, and main causes of graft loss and death. Five- and 10-year graft and patient survival rates were lower in the group with proteinuria. The main cause of death was vascular disease in both groups. The presence of posttransplantation cardiovascular disease was higher in the group with proteinuria. Persistent proteinuria was associated with graft loss (RR=4.18), patient death (RR=1.92), and cardiovascular disease (RR=2.45). In conclusion, persistent proteinuria was an independent risk factor for increased cardiovascular morbidity and mortality in renal transplant patients.

Type 2 diabetes mellitus (T2DM) in persons less than 20 years of age is increasing dramatically due to increasing obesity and inactivity, particularly in young African Americans. Risk factors for cardiovascular disease (CVD) in this population are similar to those observed in adults with T2DM, including hypertension, dyslipidemia, hyperglycemia and proteinuria. Accordingly, it seems prudent to pursue therapeutic strategies proven to reduce CVD in adult patients with DM soon after the diagnosis of T2DM in young persons.

Recent clinical trials in hypertension prove how seldom single drug therapy achieves target blood pressure (BP) and reduces cardiovascular morbidity and mortality. A natural response is the testing and marketing of fixed-dose combination products for hypertension, of which 14 have been approved in the United States since 1993. Currently, only five products are indicated by the Food and Drug Administration for initial therapy of hypertension; all include a diuretic. To achieve such an indication, studies must show not only safety and efficacy of the combination, but also BP lowering that is at least additive compared with the two agents given separately, as well as a "synergy" not present when each agent is given alone. Some advantages to initial combination therapy include greater BP reduction, improved adherence to pill taking, fewer side effects, and lower cost. The most likely candidates for initial combination therapy are patients with initial BP higher than 160/100 mm Hg, or those with a BP goal lower than the customary 140/90 mm Hg. These include patients with target organ damage, clinical cardiovascular disease, proteinuria, renal impairment, or diabetes mellitus. In many of these circumstances, an angiotensin converting enzyme inhibitor or angiotensin II receptor antagonist is frequently recommended; adding a diuretic or calcium antagonist to it is much more likely to result in achievement of the BP goal. More research is being done to explore the combination of not only two representatives from classes of conventional agents, but also other drugs that may help address the multiple manifestations of the "metabolic syndrome" that often accompanies hypertension.

Changes in renal function produced by hypertension appear to be associated with higher cardiovascular morbidity and mortality. Indices of altered renal function (eg, microalbuminuria, increased serum creatinine concentrations, decrease in estimated creatinine clearance, or overt proteinuria) are independent predictors of cardiovascular morbidity and mortality. The Framingham Heart Study documented the relevance of proteinuria for cardiovascular prognosis in the community. The International Nifedipine GITS study: Intervention as a goal in Hypertension Treatment (INSIGHT) study assessed the role of proteinuria as a very powerful risk factor. Several studies demonstrated that microalbuminuria is a predictor of cardiovascular disease. It has been shown that the presence of microalbuminuria in primary hypertension carries an elevated cardiovascular risk. Furthermore, recent data indicate that even minor derangements of renal function are associated with an increase in cardiovascular risk factors, and promote progression of atherosclerosis. All these parameters should routinely be evaluated in clinical practice, and in the future must be considered in any stratification of cardiovascular risk in hypertensive patients.

Despite the absence of precise epidemiological data, we know there are a great many patients in the conservative phase of chronic kidney disease (CKD). The incidence and prevalence of renal replacement therapy (RRT) is increasing worldwide. As well as being a large and growing clinical problem, CKD is of an economic and organizational concern, since RRT consumes a considerable proportion of health care resources. In this context, any medical intervention that may prevent the progression of CKD towards end-stage renal disease (ESRD) is extremely important. Improving the patients' cardiovascular status is also a major objective in the management of this population, as cardiovascular disease (CVD) is the leading cause of morbidity and mortality for dialysis patients. Several interventions to delay the progressive loss of renal function and/or to prevent the development of CVD are now available. These include low-protein diets; correction of calcium-phosphate disorders and anaemia; blood pressure and proteinuria control; and smoking cessation. Other interventions, such as the administration of lipid-lowering agents, anti-inflammatory drugs, and anti-oxidant agents are emerging as particularly promising therapeutic approaches, although prospective, controlled, randomized clinical trials are needed to demonstrate their clinical usefulness. Intervention in the conservative phase of CKD is likely to be more effective if performed as early as possible in the course of the disease, since it has been widely demonstrated that early and regular nephrology specialist care is associated with decreased morbidity and mortality.

Microalbuminuria (MA) i.e. slightly elevated albumin excretion in the urine, is now considered to be an atherosclerotic risk factor. MA predicts future cardiovascular disease risk in diabetic patients, in elderly patients, as well as in the general population. It has been implicated as an independent risk factor for cardiovascular disease and premature cardiovascular mortality for patients with type 1 and type 2 diabetes mellitus, as well as for patients with essential hypertension. Although microalbuminuria is associated with a certain degree of sub-clinical artherosclerotic damage, it is not known how early in the atherosclerotic process microalbuminuria appears. Epidemiological studies have shown an association between MA and insulin resistance, obesity, salt sensitivity and dyslipidaemia in patients with essential hypertension and diabetes. Patients with microalbuminuria are also characterised by an increased prevalence of left ventricular hypertrophy and retinal microvascular lesions. Microalbuminuria, is associated with an excess of other cardiovascular risk factors. The mechanisms linking microalbuminuria and risk for cardiovascular disease are not fully understood, but in subjects at risk it may be related to increased transvascular leakiness of albumin in systemic as well as renal vessels. A recent concept is that microalbuminuria is a marker of extensive endothelial dysfunction or generalised vasculopathy, which may lead to heightened atherogenic states. One possible explanation is that endothelial dysfunction might promote increased penetration of atherogenic lipoprotein particles in the arterial wall, but glycaemic status, insulin resistance, procoagulant state and adhesion molecules have all been implicated in the pathogenesis. Current evidence suggests that tight blood pressure control may reduce the risk of microalbuminuria in diabetic patients with hypertension and that inhibitors of the rennin-angiotensin system (RAS) can prevent or delay the progression of microalbuminuria to overt nephropathy in normotensive persons. ACE inhibitors are currently recognised as first-line antihypertensive therapy in diabetic patients with proteinuria, and these agents afford unique benefits in modifying the progression and severity of cardiovascular disease (CVD) as well as of diabetic nephropathy. Whether albuminuria is a risk factor or just a marker for CV disease, it identifies the high-risk diabetic patient who should be targeted for early, aggressive intervention against proven risk factors. If persistent microalbuminuria is confirmed, strict blood pressure control with added RAS inhibition should be pursued in an attempt to stabilise or even reduce microalbuminuria, preserve kidney function and possibly improve cardiovascular risk.

The mortality rate among dialysis patients is high. Although guidelines have been in place to improve outcomes in dialysis patients, new emphasis is being placed on better management of patients who are pre-end-stage renal disease (pre-ESRD)-patients with chronic kidney disease (CKD). Spearheaded by the National Kidney Foundation, the National Institute of Health, and the nephrology community at large, an effort is underway to improve the care of patients with kidney disease. We hope that improvement in health and outcomes of patients with kidney disease will be optimized through attention to care before the development of advanced renal disease. Cardiovascular disease (CVD) is an important comorbidity of chronic kidney disease, and reducing cardiovascular events in this population is an important goal for the people who care for chronic kidney disease patients. In this article, we review the available literature regarding certain risk factors for cardiovascular disease: proteinuria, hyperglycemia, hypertension, homocysteine, hyperlipidemia, and inflammation. When possible, recommendations for treatment are provided based on the information reviewed.

Kidney transplantation should be strongly considered for all medically suitable patients with chronic and end-stage renal disease (ESRD). Improvements in outcomes after renal transplantation have resulted in a more liberal selection of patients. High-risk category patients including human immunodeficiency virus (HIV)-positive, highly sensitized patients, T-cell positive cross-match, and ABO blood group-incompatible patients are now considered potential renal transplant candidates. Unfortunately, the demand for kidney transplants far exceeds the supply of available organs, causing a persistent increase in the number of patients on the waiting list with a parallel increase in the waiting time for a cadaveric kidney transplant. This has 2 major consequences. First, patients on the waiting list are getting sicker and older. Second, living donors have assumed increasing importance in renal transplantation. Pre-existing morbidities including malignancies, cardiovascular disease, infections, and coagulopathies should be extensively evaluated before proceeding to transplantation. Special attention should be given to cardiovascular risk factors because the leading cause of death after renal transplant is cardiovascular disease. A full immunologic evaluation with ABO blood group determination, human leukocyte antigen (HLA) typing, screening for antibody to HLA phenotypes, and cross-matching need to be gathered before transplantation to avoid antibody-mediated hyperacute rejection or to proceed with specific protocols in highly sensitized or in positive T-cell cross-match patients. With the increased rate of donation from living donors, regular follow-up evaluation of kidney donors is recommended to detect hypertension or proteinuria in those who may develop it.

Diabetes mellitus increases the risk for hypertension and associated cardiovascular diseases, including coronary, cerebrovascular, renal and peripheral vascular disease. The risk for developing cardiovascular disease is increased when both diabetes and hypertension co-exist; in fact, over 11 million Americans have both diabetes and hypertension. These numbers will continue to climb, internationally, since the leading associated risk for diabetes development, obesity, has reached epidemic proportions, globally. Moreover, the frequent association of diabetes with dyslipidemia, as well as coagulation, endothelial, and metabolic abnormalities also aggravates the underlying vascular disease process in patients who possess these comorbid conditions. The renin-angiotensin-aldosterone system (RAS) and arginine vasopressin (AVP) are overactivated in both hypertension and diabetes. Drugs that inhibit this system, such as ACE inhibitors and more recently angiotensin receptor antagonists (ARBs), have proven beneficial effects on the micro- and macrovascular complications of diabetes, especially the kidney. The BRILLIANT study showed that lisinopril reduces microalbuminuria better than CCB therapy. Numerous other long-term studies confirm this association with ACE inhibitors including the HOPE trial. Furthermore, the European Controlled trial of Lisinopril in Insulin-dependent Diabetes (EUCLID) study, showed that lisinopril slowed the progression of renal disease, even in individuals with mild albuminuria. In fact, there are now five appropriately powered randomized placebo-controlled trials to show that both ACE inhibitors and ARBs slow progression of diabetic nephropathy in people with type 2 diabetes. These effects were shown to be better than conventional blood pressure lowering therapy, including dihydropyridine CCBs. In patients with microalbuminuria, ACE inhibitors and ARBs reduce the progression of microalbuminuria to proteinuria and provide a risk reduction of between 38 and 60% for progression to proteinuria. This is important since microalbuminuria is known to be associated with increased vascular permeability and decreased responsiveness to vasodilatory stimuli. Recently, increased AVP levels have been lined to microalbuminuria and hyperfiltration in diabetes. The microvascular and macrovascular benefits of ACE inhibition, ARBs and possible role of AVP antagonists in diabetic patients will be discussed, as will be recommendations for its clinical use.
