Chronic kidney disease (CKD) shares major risk factors with cardiovascular disease(CVD), including hypertension and diabetes mellitus. In patients with hypertensive kidney disease and diabetic nephropathy, inhibitors of the renin-angiotensin system (RAS) significantly reduce the risk of renal and cardiovascular endpoints. Whether the renoprotective effects of RAS inhibitors can be fully accounted for by blood pressure reductions or whether other mechanisms are involved has not been clearly established. Because RAS inhibitors reduce albuminuria and slow progression of kidney disease, they are recommended as fi rst-line antihypertensive agents in patients with CKD, who often require aggressive treatment with > or = 2 drugs to reach the goal blood pressure (< 130/80 mm Hg). Greater RAS inhibition with higher-than-usual doses of a single agent or dual RAS inhibition with an angiotensin-converting enzyme inhibitor and an angiotensin receptor blocker may be necessary for maximum renoprotective effects. Ongoing clinical trials assessing treatment and prevention of CKD may resolve unanswered questions about RAS inhibition in patients with hypertension and/or diabetes.

Chronic kidney disease (CKD) is a worldwide problem. This study was designed to survey the prevalence and risk factors for CKD in Korea. The 2,356 subjects were selected in proportion to age, gender, and city. Subjects 35 yr of age or older were selected from 7 cities. Estimated glomerular filtration rate (eGFR) was calculated using the Modification of Diet in Renal Disease (MDRD) Study equation, with albuminuria defined as a urine albumin to creatinine ratio of 30 mg/g or more. The overall prevalence of CKD was 13.7%. The prevalences of CKD according to stage were 2.0% stage 1, 6.7% stage 2, 4.8% stage 3, 0.2% stage 4, and 0.0% stage 5. The prevalences of microalbuminuria and macroalbuminuria were 8.6% and 1.6%, respectively. The prevalence of eGFR less than 60 mL/min/1.73 m(2) was 5.0%. Age, body mass index (BMI), hypertension, diabetes mellitus, systolic blood pressure (SBP), diastolic blood pressure (DBP), and fasting blood glucose were independent factors related to the presence of CKD. In conclusions, Korea, in which the prevalence of CKD is increasing, should prepare a policy for early detection and appropriate treatment of CKD. The present data will be helpful in taking those actions.

The key messages of these guidelines on chronic kidney disease are: Chronic kidney disease (CKD) is a public health problem due to its wide distribution, high rate of complications and cost. CKD is a common condition, its prevalence being about 10%, and is treatable if it is detected on time. A patient with CKD has a higher risk of cardiovascular mortality than of progression of its underlying renal disease. A new definition of CKD, based on estimated Glomerular Filtration Rate (eGFR) and kidney damage, facilitates its detection and management. CKD is detected with three simple tests: 1) Blood pressure measurement, 2) Detection of proteinuria or albuminuria in an isolated urine sample, and 3) Estimation of renal function (eGFR), based on serum creatinine, age, gender and race. The CKD risk groups are individuals with diabetes, hypertension and a family history of renal disease. The most cost-effective measures are to detect and treat diabetic and hypertensive patients in the community. Therapy must emphasize the maximal reduction of cardiovascular risk. The complications of CKD such as anemia and renal osteodystrophy can be identified and treated on time. Most patients with chronic kidney disease are detected in the community, therefore their initial care must be organized at the level of primary care, along with programs for hypertension and diabetes.

Chronic kidney disease (CKD) is more likely to progress to end-stage renal disease (ESRD) in African Americans while the reasons for this are unclear. The metabolic syndrome is a risk factor for the development of diabetes, cardiovascular disease, and has been recently linked to incident CKD. Historically, fewer African Americans meet criteria for the definition of metabolic syndrome, despite having higher rates of cardiovascular mortality than Caucasians. The presence of microalbuminuria portends increased cardiovascular risks and has been shown to cluster with the metabolic syndrome. We recently reported that proteinuria is a predictor of CKD progression in African American hypertensives with metabolic syndrome. In this review we explore the potential value of including CKD markers--microalbuminuria/proteinuria or low glomerular filtration rate (GFR)-in refining the cluster of factors defined as metabolic syndrome, ie, "cardiorenal metabolic syndrome."

Chronic kidney disease (CKD) is a major health problem for the underdeveloped countries of southeast Asia, home to more than 2 billion people. The true incidence and prevalence in the region is not known, but estimates suggest that the prevalence may be more than that reported in Western societies. The majority of affected individuals are young and in the most productive years of their lives. The looming epidemic of diabetes and hypertension is likely to further add to the disease burden. A high prevalence has been reported from some regions, suggesting the presence of unique etiologic factors. A large proportion of patients present late, with advanced kidney failure and multiple complications. Management is hampered by the lack of health care services, especially in the rural areas. The health care expenditure by the governments in these countries is very low, and there are no regional or national policies for chronic disease management including CKD. There is a major shortage of trained nephrologists. In absence of any government or private reimbursement, most patients cannot afford the high treatment cost. Renal replacement therapy is available only to a minority. The practice of dialysis in the region is not standardized and a large number of patients develop complications. There is an urgent need to develop CKD detection and prevention programs. Investigations are required to characterize the unique etiologic factors in different geographic regions so that prevention programs can be targeted appropriately. Cost-cutting strategies would make renal replacement therapy accessible to the general population. According sufficient prominence to CKD in education programs would help increase awareness.

Chronic kidney disease (CKD) is a major public health concern. The high prevalence of reduced estimated glomerular filtration (eGFR) in the elderly has led to speculation as to whether it should really be regarded as a disease in all. Patients with CKD exhibit considerable cardiovascular morbidity and mortality but until recently data regarding the natural history of CKD, particularly in the elderly, has been somewhat lacking. As such the clinical significance of K/DOQI's CKD definition in terms of additional morbidity, mortality and progression to end-stage renal disease (ESRD) remains uncertain. Data have shown that death from cardiovascular disease is far more common than progression to renal replacement therapy in the elderly. Factors which increase the risks of progression to ESRD include younger age, proteinuria and diabetes. Although the elderly have high rates of cardiovascular death, comparatively younger patients with CKD have substantially increased relative risks of death. Specialist renal review should be targeted towards these high-risk patients while the majority of elderly patients can be safely monitored in primary care. It remains doubtful whether labelling all elderly CKD patients with a 'disease' confers any additional benefit.

Chronic kidney disease (CKD) is a risk factor for poor outcomes in patients with coronary artery disease (CAD), but it is unknown whether CKD influences the efficacy of alternative CAD treatment strategies. Thus, we compared outcomes in stable CAD patients with and without CKD randomized to percutaneous coronary intervention (PCI) and optimal medical therapy (OMT) or OMT alone in a post hoc analysis of the 2,287 patient COURAGE study. At baseline, 320 patients (14%) had CKD defined as a glomerular filtration rate of <60 mL/min/1.73 m(2), as estimated by the abbreviated 4-variable Modification of Diet in Renal Disease equation. The patients with CKD were older (68 +/- 9 vs 61 +/- 10 years; p <0.001) and more often had diabetes mellitus (42% vs 33%; p = 0.002), hypertension (81% vs 65%; p <0.03), heart failure (13% vs 3.4%; p <001), and three-vessel CAD (37% vs 29%, p = 0.01). After adjustment for these differences, CKD remained an independent predictor of death or nonfatal myocardial infarction (hazard ratio 1.48, 95% confidence interval 1.15 to 1.90). PCI had no effect on these outcomes. Furthermore, at 36 months, a similar percentage of patients with CKD treated with OMT (70%) and PCI plus OMT (76%) were angina free compared to patients without CKD. In conclusion, CKD is an important determinant of clinical outcomes in patients with stable CAD, regardless of the treatment strategy. Although PCI did not reduce the risk of death or myocardial infarction when added to OMT for patients with CKD, it also was not associated with worse outcomes in this high-risk group.

Chronic kidney disease (CKD) is a major public health problem and can result in end-stage renal disease with need for dialysis or transplantation. In Europe up to 12% of the adult population had some renal impairment, while in the United States the end stage of CKD has increased dramatically from 209.000 in 1991 to 472.000 in 2004. Diabetes and hypertension are major causes of kidney pathology. Infection, particularly ascending infection, is more common with increasing age, as both immune function declines and associated pathology predisposing to infection, such as obstructive uropathy, becomes more common. Most pathological changes in the kidney appear to be initiated by oxidative stress, followed by an inflammatory reaction. Oxidative stress results from an imbalance between free radicals and their detoxification by endogenous and exogenous scavengers, including polyunsaturated fatty acids (PUFA). Recent studies showed that PUFA supplementation slowed the rate of loss of renal function in patients with IgA nephropathy. Then, studies of omega-3 supplementation in dialysis patients describe salutary effects on triglyceride levels and dialysis access patency. We examined the relationship between total plasma PUFA levels and change in creatinine clearance over a three-year follow-up in the older persons enrolled in the InCHIANTI study, a population-based epidemiology study conducted in Tuscany, Italy. This study showed that older adults with low total plasma PUFA levels have a greater decline in creatinine clearance over three years of follow-up. These findings suggest that a higher dietary intake of PUFA may be protective against progression to chronic kidney disease.

Chronic kidney disease (CKD) is a recognized risk multiplier for the development of cardiovascular disease (CVD), with CVD events representing the leading cause of morbidity and mortality in patients with CKD. The nature of CKD as a risk state relates both to the nature of CKD and the antecedent development of CVD. In addition, patients with CKD have increased rates of multiple conventional cardiac risk factors. Although early data regarding the relationship between CVD and CKD were limited because of the need for large data sets and multivariable analysis, the importance of recognizing this complex relationship is now clear. The essence of the relationship appears to be bidirectional, and therapy directed at improving natural history of chronic disease on one system generally improves prognosis in the other. Specifically, CVD outcomes have been shown to improve with the treatment of risk factors commonly found in association with CKD, including hypertension, diabetes, dyslipidemia, albuminuria, and smoking, as well as appropriate renin-angiotensin-aldosterone system blockade and antiplatelet therapy. Once hospitalized, management of acute coronary syndromes represents a key area of clinical investigation. The goal of this article is to highlight the importance of these topics in improving cardiovascular outcomes and use of appropriate treatment in CKD.

Chronic kidney disease (CKD) is associated with a higher risk for stroke in studies from developed countries. This prospective study was conducted to study the clinical profile, management, and outcome of stroke in patients of chronic kidney disease who had been admitted in our institute during the period from December 2004 to December 2006. A higher incidence of stroke was found in men and in the fifth decade of life. Hypertension and diabetes were found in 88.8 and 48.1% of the patients respectively. CKD was detected for the first time during stroke evaluation in 55.5% of the patients. Stroke was due to cerebral infarction in 48.14% and due to cerebral hemorrhage in 40.7% of the patients. Surgical intervention was needed in 14.8% of all patients while stroke was managed medically in the rest. Over 70% of the patients were discharged after they showed improvement in the symptoms.
