Changes in renal function related with essential hypertension are associated with an elevated cardiovascular morbidity and mortality. Indices of altered renal function (e.g., microalbuminuria, increased serum creatinine concentrations, decrease in estimated creatinine clearance or GFR, and 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 INSIGHT Study assessed the role of proteinuria as a risk factor in essential hypertension. The presence of proteinuria at baseline turned out to be a very potent predictor for the development of cardiovascular events and death in patients with essential hypertension and one or more associated cardiovascular risk factors. Recent data indicate that minor derangements of renal function, including proteinuria, are associated, both in the community and in the hypertensive population, with the clustering of cardiovascular risk factors observed in metabolic syndrome that promote progression of atherosclerosis. Renal function has to be routinely evaluated in every hypertensive patient, and the presence of minor alterations considered in the stratification of cardiovascular risk in hypertensive patients.

Hypertension and hypertension-associated ESRD are epidemic in society. The mechanisms responsible for renal progression in mild to moderate hypertension and those groups most at risk need to be identified. Historic, epidemiologic, clinical, and experimental studies on the pathogenesis of hypertension and hypertension-associated renal disease are reviewed and an overview/hypothesis for the mechanisms involved in renal progression is presented. There is increasing evidence that hypertension may exist in one of two forms/stages. The first stage, most commonly observed in early or borderline hypertension, is characterized by salt-resistance, normal or only slightly decreased GFR, relatively normal or mild renal arteriolosclerosis, and normal renal autoregulation. This group is at minimal risk for renal progression. The second stage, characterized by salt-sensitivity, renal arteriolar disease, and blunted renal autoregulation, defines a group at highest risk for the development of microalbuminuria, albuminuria, and progressive renal disease. This second stage is more likely to be observed in blacks, in subjects with gout or hyperuricemia, with low level lead intoxication, or with severe obesity/metabolic syndrome. The two major mechanistic pathways for causing impaired autoregulation at mild to moderate elevations in BP appear to be hyperuricemia and/or low nephron number. Understanding the pathogenetic pathways mediating renal progression in hypertensive subjects should help identify those subjects at highest risk and may provide insights into new therapeutic maneuvers to slow or prevent progression.

The metabolic syndrome is a risk factor for the development of diabetes and cardiovascular disease; however, no prospective studies have examined the metabolic syndrome as a risk factor for chronic kidney disease (CKD). A total of 10,096 nondiabetic participants who were in the Atherosclerosis Risk in Communities study and had normal baseline kidney function composed the study cohort. The metabolic syndrome was defined according to recent guidelines from the National Cholesterol Education Program. Incident CKD was defined as an estimated GFR (eGFR) <60 ml/min per 1.73 m2 at study year 9 among those with an eGFR > or =60 ml/min per 1.73 m2 at baseline. After 9 yr of follow-up, 691 (7%) participants developed CKD. The multivariable adjusted odds ratio (OR) of developing CKD in participants with the metabolic syndrome was 1.43 (95% confidence interval [CI], 1.18 to 1.73). Compared with participants with no traits of the metabolic syndrome, those with one, two, three, four, or five traits of the metabolic syndrome had OR of CKD of 1.13 (95% CI, 0.89 to 1.45), 1.53 (95% CI, 1.18 to 1.98), 1.75 (95% CI, 1.32 to 2.33), 1.84 (95% CI, 1.27 to 2.67), and 2.45 (95% CI, 1.32 to 4.54), respectively. After adjusting for the subsequent development of diabetes and hypertension during the 9 yr of follow-up, the OR of incident CKD among participants with the metabolic syndrome was 1.24 (95% CI, 1.01 to 1.51). The metabolic syndrome is independently associated with an increased risk for incident CKD in nondiabetic adults.

The metabolic syndrome (MS) has been implicated as an important nonimmunologic risk factor for chronic renal transplant dysfunction. The aim of this study was to determine the impact of the MS on outcomes in simultaneous kidney-pancreas transplantation (SKPT). Data were available on 241 patients enrolled in a prospective, multicenter randomized study of daclizumab compared with no antibody induction in SKPT. Presence of MS before and after SKPT was defined using NCEP-ATP III (National Cholesterol Education Program Adult Treatment Panel III) criteria. Body mass index (BMI) was used as a surrogate for waist circumference. MS was present in 59% of patients pretransplantation but only in 19% of patients 1 year after SKPT (P < .0001). Demographic and transplant characteristics were well matched for those with MS (MS+) and without MS (MS-) at 1 year. Presence of MS at 1 year was associated with the following changes at 3 years: increased serum creatinine level (1.65 mg/dL MS- vs 2.05 mg/dL MS+; P = .13); decreased modification of diet in renal disease calculated glomerular filtration rate (GFR; 58 mL/min MS- vs 48 mL/min MS+; P = .02); increased HgbA1C level (5.6% MS- vs 6.6% MS+; P < .001); and lower pancreas graft (PG) survival rate (88% MS- vs 71% MS+; P = .01). Linear regression analysis identified MS+ and the subgroup of MS+ without functioning PG at 1 year as independent risk factors for renal dysfunction, whereas MS+ with functioning PG at 1 year was not a risk factor for renal dysfunction. Presence of MS at 1 year is associated with long-term renal dysfunction after SKPT. Efforts to decrease early PG failure may help mitigate against MS-associated renal dysfunction.

In recent years, increasing evidence has been provided that even minor renal dysfunction is a powerful cardiovascular risk factor that induces typical cardiovascular alterations and thus predisposes to coronary heart disease as well as to noncoronary cardiovascular problems. This first had been noted in patients with diabetes but now has been confirmed amply in patients without diabetes as well. Numerous heterogeneous abnormalities have been described in patients with early renal dysfunction (e.g., microalbuminuria, reduced estimated GFR). One final common pathway seems to be endothelial cell dysfunction. The link between albuminuria and generalized endothelial cell dysfunction (as indicated by diminished flow-mediated vasodilation, markers of endothelial cell dysfunction, sloughed off endothelial cells, and high transcapillary albumin escape rate) is unclear. In patients with early renal dysfunction, a long list of classical and nonclassical cardiovascular risk factors have been identified: Elevated asymmetric dimethyl-l-arginine concentrations, markers of microinflammation, oxidative stress, features of metabolic syndrome, abnormal adipokine concentrations, dyslipidemia, inappropriate activation of the renin-angiotensin system, and sympathetic overactivity. The mechanisms that link dysfunction of the kidney and the cardiovascular system are being sought. The most interesting unifying concept, however, is deranged fetal programming linking nephron underdosing to the increased cardiovascular risk.

The First Hungarian Therapeutic Consensus Conference took place on 3rd Nov. 2003 with the participation of 9 medical societies. Over the past 2 years the results of new major studies have been published and the American ATP III has also updated its guidelines issued in 2004. Based on the above proposals, the Second Hungarian Therapeutic Consensus Conference held on 3rd Nov. 2005 partly confirmed its earlier suggestions, but made some changes as well. Within the high risk category the Conference optionally created a very high risk group from those patients who - in addition to their cardiovascular disease--have either diabetes or metabolic syndrome or acut coronaria syndrome or who are chain smokers. We have included - as a complement - into the asymptomatic high risk category such newly emerging risk factors, one of which already in itself means high risk: ankle/arm index < or = 0.9, GFR <60 ml/min, microalbuminuria (30-300 mg), preclinical atherosclerosis (plaque). Besides, 4 other risk factors were also categorised such as Lp/a (> or = 30 mg/dl), CRP (> or = 3mg/l), homocysteine (> or = 12 micromol), familiarity--atherogenic gene constellation, but only the presence of at least two of these verify high risk. In very high risk group the goals of 3.5 mmol/l and 1.8 mmol/l were determined as therapeutic option. The goal in obese patients--expressed earlier only in BMI--can now be equally determined by the abdominal circumference (94 cm for men, 80 cm for women respectively). ACE inhibitors were recommended earlier as a preventive therapy in case of dysfunction of the left ventricle, while at present they are suggested for all patients with cardiovascular disease. In the recent recommendations guidelines related to nutrition, smoking, exercise have also been included.

Overweight and obesity are associated with increased cardiovascular risk. Some studies have demonstrated that they also can result in renal damage. The aim of this study was to assess the prevalence of renal insufficiency (RI), defined as a GFR <60 ml/min per 1.73 m2, in a cohort of 4585 patients who attended primary care with essential hypertension and a body mass index > or =25 kg/m2. The patients were classified as overweight and obese according to body mass index (25 to 29.9 and > or =30 kg/m2, respectively). Abdominal obesity was defined as a waist circumference > or =88 and 102 cm in women and men, respectively. Both groups had a high prevalence of metabolic syndrome (Adult Treatment Panel III). The prevalence of RI was high in both the overweight group (22.7%; 95% confidence interval [CI] 20.6 to 24.9) and in the obese group (22.8%; 95% CI 21.0 to 24.7). The presence of diabetes increased the risk for RI (odds ratio 1.83; 95% CI 1.55 to 2.16). The prevalence of RI was greater in patients with abdominal obesity (23 versus 17%; P < 0.001). In the presence of abdominal obesity, cardiovascular risk factors and components of the metabolic syndrome also were more prevalent. The higher risk for RI with abdominal obesity persisted even after adjustment for dyslipidemia, elevated blood glucose levels, and other variables that are associated with RI (adjusted odds ratio 1.40; 95% CI 0.84 to 2.33). It was concluded that patients who have hypertension and visceral obesity and attend primary care present a higher prevalence of metabolic syndrome and RI.

Chronic kidney disease (CKD) is increasingly recognized not only as a cause of end-stage renal disease but also as a cause of cardiovascular disease. Importantly, it is intimately associated with non-healthy lifestyles such as obesity, metabolic syndrome, hypertension, diabetes mellitus, smoking, and heavy drinking. To define CKD direct measurement of GFR or estimation of GFR (eGFR) is required. Japan Society of Nephrology is asking nationwide project to create "original" equation without using ethnic factor to obtain eGFR. Early detection and early treatment are vital to prevent not only CKD progression but also cardiovascular events. A comprehensive health education campaign and screening of the general populace are needed in order to detect CKD early. The control of hypertension, dyslipidemia, proteinuria, obesity, are intervention strategies that retard or prevent progression of CKD. Blockade of the renin-angiotensin system can be beneficial, especially if proteinuria is present.

Several recent prospective studies have reported that obesity is associated with an increased risk for chronic kidney disease (CKD), but it is unknown whether weight gain increases the risk for CKD if one remains within the "normal" category of body mass index (BMI). We prospectively followed a cohort of 8792 healthy men who had no known risk factors for CKD and participated in a comprehensive health evaluation program at a large worksite. During 35,927 person-years of follow-up, 427 new incident cases of CKD (estimated GFR <64 ml/min per 1.73 m(2)) developed. Cox proportional hazards modeling revealed that in both the normal-weight and overweight groups, a U-shaped association between weight change categories and development of CKD was observed after adjustment for age, baseline GFR, baseline BMI, HDL, fasting blood glucose, uric acid, and exercise habits. The lowest risk for CKD was observed among those whose weight changed -0.25 to <0.25 kg/yr (P < 0.001 for quadratic term). Weight change as a time-dependent variable was significantly related to CKD incidence. These relationships remained significant even after further adjustment for Homeostasis Model Assessment of Insulin Resistance, high-sensitivity C-reactive protein, systolic BP, diastolic BP, metabolic syndrome, incident hypertension, or incident diabetes. In summary, increases in body weight are independently associated with an increased risk for CKD, even when the BMI remains within the normal range.

CKD is a common, harmful but treatable disease. Since the number of CKD patients is huge, the efficient and practical measures for early detection and diagnosis are needed. To achieve this goal, systematic screening and collaborative work between nephrologists and primary care physicians should be established. Urinalysis, especially urinary protein detection, and measurement of serum creatinine level (estimation of GFR) are the two major tests to detect CKD. These two clinical tests should be done for those people who have higher risk of CKD, i.e., those with diabetes, hypertension, metabolic syndrome, obesity, family history of CKD. Urine testing for general population is also necessary to detect glomerulonephritis. The earlier CKD is diagnosed, the better the outcome is.
