Diabetic nephropathy is a major cause of end-stage renal failure (ESRF) in patients with both type 1 and type 2 diabetes. Many factors such as genetic and non-genetic promoters, hypertension, hyperglycemia, accumulation of advanced glycation end products (AGEs), dyslipidemia, albuminuria and proteinuria influence the progression of this disease. It is important to determine pathogenesis and treatment of this disease. However, it is difficult to investigate since human diabetes is a heterogeneous and multifactorial disease. Therefore, most of these mechanisms have been investigated in animal experiments. KK/Ta mice have a clearly different genetic background in terms of body weight, blood glucose, impaired glucose tolerance (IGT), urinary albumin excretion and serum triglyceride than BALB/c mice. Renal lesions of KK/Ta mice closely resemble those in human early diabetic nephropathy. Thus, the KK/Ta mouse may serve as a suitable model for the study of type 2 diabetes and early diabetic nephropathy in humans. We reviewed genetic susceptibility using genome-wide linkage analysis and differential display polymerase chain reaction (DD-PCR) or Northern blot analysis, and treatment of diabetic nephropathy using angiotensin type 1 (AT1) receptor blockers (ARB) or thiazolidinediones (TZDs) in KK/Ta mice.

Depending on the reduction in glomerular filtration rate (GFR) as a measure of renal insufficiency and depending on their age, patients with chronic kidney disease have a 1.5 to 1,000-fold higher cardiovascular risk. Renal insufficiency is inherently an independent risk factor for cardiovascular events, which is likewise the case for patients also presenting with hypertension or diabetes mellitus. When cardiac insufficiency or coronary heart disease is already manifest, the GFR is the most important predictive factor for the patients' further survival. Proteinuria or albuminuria as signs of kidney disease are also important markers and correlate with the cardiovascular risk in the range of both macro- and microalbuminuria. Endothelial dysfunction, oxidative stress, dyslipidemia, and increased atherosclerosis are being discussed as pathophysiological mechanisms of elevated cardiovascular risk.

Childhood chronic kidney disease commonly progresses toward end-stage renal failure, largely independent of the underlying disorder, once a critical impairment of renal function has occurred. Hypertension and proteinuria are the most important independent risk factors for renal disease progression. Therefore, current therapeutic strategies to prevent progression aim at controlling blood pressure and reducing urinary protein excretion. Renin-angiotensin-system (RAS) antagonists preserve kidney function not only by lowering blood pressure but also by their antiproteinuric, antifibrotic, and anti-inflammatory properties. Intensified blood pressure control, probably aiming for a target blood pressure below the 75th percentile, may exert additional renoprotective effects. Other factors contributing in a multifactorial manner to renal disease progression include dyslipidemia, anemia, and disorders of mineral metabolism. Measures to preserve renal function should therefore also comprise the maintenance of hemoglobin, serum lipid, and calcium-phosphorus ion product levels in the normal range.

Chronic kidney disease (CKD) is characterized by proteinuria and kidney dysfunction caused by multiple factors. Metabolic disorders such as diabetes, dyslipidemia and hypertension are involved in the underlying pathological mechanisms of CKD and cardiovascular disease (CVD). In patients with CKD, CVD is a major cause of morbidity and mortality. Recent clinical studies have revealed that intervention by angiotensin II blockade with ARB and ACEI reduces CKD and CVD. Accordingly, earlier intervention to metabolic disorders with blockers for angiotensin II and aldosterone may prevent CKD as well as CVD associated with CKD.

Diabetes mellitus is a well-established independent risk factor for stroke and is associated with high mortality. Risk factors or risk markers for a first stroke were classified according to their potential for modification (nonmodifiable, modifiable, or potentially modifiable) and strength of evidence (well documented or less well documented). Modifiable risk factors include hypertension, exposure to cigarette smoke, diabetes, atrial fibrillation and certain other cardiac conditions, dyslipidemia, carotid artery stenosis, sickle cell disease, postmenopausal hormone therapy, poor diet, physical inactivity, and obesity and body fat distribution. Some of parameters are usefull as screening test to predict the incidence of stroke in diabetic patients in the future, such as UKPDS Risk Engine, incidence of carotid bruit featuring the stenosis of carotid artery, QTc interval prolongation and proteinuria. The real action must be taken to prevent the stroke when high risk patient is found. The modifiable and potentially modifiable risk factors that have been recommended by numbers of expert committee have to be modified immediately. In case with stenosis of carotid artery, the endarterectomy and carotid stenting have become popular and acceptable treatment in USA and Europe. It must be considered by Indonesian physicians to decrease the incidence of stroke.

Obesity and hyperlipidemia are common findings after kidney transplantation (Tx), and may represent independent risk factors for development of atherosclerosis and chronic allograft nephropathy. In a prospective metabolic study, we monitored a total of 68 obese transplant patients (body mass index > 30 kg/m2) with dyslipidemia. We compared findings of a new therapeutic regimen 1 year (at baseline) and 2 years after renal transplantation. Using the Subjective Global Assessment, at the end of the first year an Individualized Hypoenergetic-Hypolipidemic diet was initiated. Subsequently, after withdrawal of corticosteroids IHHD was regularly supplemented with statins (atorvastatin 10-20 mg/day) and followed-up for 2 years. All patients were on a regimen of cyclosporin A or tacrolimus and mycophenolate mofetil. During the study period, there was a significant decrease in BMI (p<0.25) and an increase in adiponectin levels (p<0.01). Long-term therapy was associated with a significant decrease in serum leptin (p<0.01) and lipid metabolism parameters (p<0.01). Insulin clearance mean systolic and diastolic blood pressure, proteinuria and apo-lipoprotein E isoforms did not differ significantly. Based on our results, we can assume that obesity and hyperlipidemia after renal transplantation can be effectively treated by modified immunosuppression (corticosteroid withdrawal), statins and long-term diet (IHHD). The increased levels of adiponectin may be a marker of reduced atherosclerosis and chronic allograft nephropathy.

The natural history of most chronic kidney diseases (CKD) indicates that glomerular filtration gradually declines over time, progressing to more advanced stages of kidney failure. Since the publication of the first studies by the Modification of Diet in Renal Disease (MDRD) Study Group, numerous factors have been identified that can accelerate this progression. Some are dependent on the etiology, but other are common to all and may accelerate progression of kidney disease: Non-modifiable progression factors for CKD: - Etiology of kidney disease - Degree of initial kidney function - Gender - Age - Ethnicity/Other genetic factors - Birth weight Modifiable progression factors for CKD: - Proteinuria - High blood pressure - Poor glycemic control in diabetes - Smoking - Obesity - Metabolic syndrome/Insulin resistance - Dyslipidemia - Anemia - Metabolic factors (Ca/P, uric acid) - Use of nephrotoxic drugs. Therapeutic intervention on these factors has shown that it reduce the rate of progression of CKD (Strength of Recommendation A).There is no clear evidence that correction of these factors slows CKD (Strength of Recommendation C), although it has been shown to have a beneficial effect on cardiovascular risk at other levels.

Metabolic syndrome (MS) encompasses a series of diseases which, when combined, increase vascular risk more than the sum of their individual risks. Insulin resistance (IR) is one of the basic components of MS. - Abdominal fat distribution is an IR marker and is associated to factors increasing vascular risk such as dyslipidemia, high blood pressure, and hyperglycemia, components of the so-called metabolic syndrome. - IR is related to glomerular sclerosis and renal failure through several mechanisms, Including genetic and environmental factors, and stimulation of the renin-angiotensin-aldosterone system. - IR usually precedes development of DM, and therefore contributes to its early identification. MS increases the risk of chronic complications from DM and is associated to an increased prevalence of cardiovascular disease, particularly coronary heart disease, increasing mortality from this cause. - The presence of MS in DM2 is usually associated to a greater prevalence of microalbuminuria or proteinuria and peripheral polyneuropathy.

TREATMENT OF ARTERIAL HYPERTENSION - Blood pressure (BP) should be regularly measured in all patients with CKD (Strength of Recommendation C). - BP control and proteinuria reduction delay progression of CKD (Strength of Recommendation A) and reduce cardiovascular risk (Strength of Recommendation C). Thus, control of both factors should be the treatment objective. - The BP target in patients with CKD should be < 130/80 mmHg, and 125/75 mmHg if proteinuria is > 1 g/24 hours (Strength of Recommendation A). - Lifestyle changes should be made: low-sodium diet (less than 100 mEq/day of sodium or 2.4 g/day of salt); weight reduction if patient is overweight (body mass index 20-25 kg/m2); regular aerobic physical exercise and moderate alcohol intake for BP control and prevention of cardiovascular risk (Strength of Recommendation A). - The choice of the antihypertensive drug in patients with CKD depends on the etiology of CKD, cardiovascular risk, or presence of clinical or subclinical cardiovascular disease (Strength of Recommendation A). - Two or more antihypertensive drugs are usually required to control blood pressure in patients with CKD (Strength of Recommendation B), and will frequently include a diuretic, which in stages 4-5 should be a loop diuretic (Strength of Recommendation B). - Renin-angiotensin-aldosterone system (RAAS) inhibitors are first choice drugs in patients with diabetic nephropathy, patients with non-diabetic nephropathy with a protein/creatinine ratio higher than 200 mg/g, and patients with heart failure (Strength of Recommendation A). The combination of ACEIs and ARBs is indicated for reducing proteinuria that remains high despite treatment with a RAAS inhibitor, provided potassium levels do not exceed 5.5 mEq/L (Strength of Recommendation B). - When RAAS blockers are started or their dose is changed in patients with advanced CKD, kidney function and serum potassium levels should be monitored at least after 1-2 weeks. DIAGNOSIS AND TREATMENT OF DYSLIPIDEMIA - A complete evaluation of the lipid profile including total cholesterol, LDL-C, HDL-C, and triglycerides should be performed in any patient with CKD at baseline and at least annually (Strength of Recommendation B). - In patients with stage 4-5 CKD and LDL-C >or= 100 mg/dL, treatment to decrease levels to < 100 mg/dL should be considered because of their high CV risk. This reduction is recommended in secondary prevention and in primary prevention in diabetic patients. Lipid-lowering treatment is recommended in all other patients, although no evidence showing its benefits is available yet (Strength of Recommendation C). - In patients with stage 4-5 CKD and triglyceride levels >or= 500 mg/dL which are not corrected by treating the underlying cases, treatment with triglyceride-lowering drugs may be considered to reduce the risk of pancreatitis. However, treatment with fibrates should be used with caution, and these drugs should not be associated to statins due to the risk of rhabdomyolysis (Strength of Recommendation C). There is little experience on the efficacy and safety of omega-3 fatty acids for the treatment of hypertriglyceridemia in patients with grade 4-5 CRF, but they may be considered a possibly safer alternative to fibrates (Strength of Recommendation C). SMOKING - Smoking is a cardiovascular risk factor and a risk factor for progression of kidney disease in patients with CRF (Strength of Recommendation B). - Use of active measures to achieve smoking cessation is recommended in patients with CRF (Strength of Recommendation C). HOMOCYSTEINE - Hyperhomocysteinemia has been postulated as a cardiovascular risk factor in the general population and in kidney patients, but the available evidence is not consistent. - There is no evidence that vitamin therapy decreases cardiovascular risk in patients with CRF, and recommendation of routine vitamin measurement and start of vitamin therapy to reduce cardiovascular risk in these patients is therefore questionable (Strength of Recommendation B). LEFT VENTRICULAR HYPERTROPHY - Left ventricular hypertrophy (LVH) is a cardiovascular risk factor in patients with CRF (Strength of Recommendation B). - It is advisable to perform an echocardiogram at baseline and every 12-24 months and to consider treatments allowing for LVH regression (Strength of Recommendation C). The approach to LVH should be early and multifactorial because its reversibility is limited once established (Strength of Recommendation C). - RAAS blockade with ACEIs or ARBs partially reverts LVH in patients with CRF (Strength of Recommendation B). ANTI-PLATELET AGGREGATION - Because of the high cardiovascular risk in patients with CKD, anti-platelet aggregant therapy, especially low-dose aspirin, would be indicated in patients with type 2 diabetes as primary prevention, and in all patients with CKD as secondary prevention. There is however no evidence of the benefits of anti-platelet aggregant therapy in primary prevention in patients with CKD, particularly in stages 4-5; indication for treatment in this situation should therefore be individualised because of its greater risk of bleeding. - Adequate good blood pressure control should previously be achieved to minimise the risk of haemorrhagic stroke (Strength of Recommendation C).

Dyslipidemia is an important complication affecting kidney transplant recipients. Statins, the first-line therapy, are often insufficient. Ezetimibe may be effective in combination with statin therapy. We performed a retrospective study to determine the safety and efficacy of ezetimibe treatment in addition to statin therapy among 27 stable renal transplant patients with uncontrolled hypercholesterolemia. We obtained fasting lipid profiles at 3 and 6 months before ezetimibe therapy, while the patients were receiving statins at maximum tolerated doses. Statin doses were stable during the study. All patients received ezetimibe (10 mg) once daily. Fasting lipid profile, kidney function, liver enzymes, creatine kinase, and immunosuppressive drug levels were obtained at baseline as well as at 3 and 6 months post-ezetimibe initiation. Combination therapy resulted in median reductions in total cholesterol of 29% (interquartile range [IQR] 12-39; P = .0001) and 28% (IQR 9-38; P = .0001); in low-density lipoprotein cholesterol of 34% (IQR 16-61; P = .0001) and 44% (IQR 24-56; P = .0001); and in triglycerides of 14% (IQR 4-31; P = .01) and 19% (IQR 1-37; P = .006) at 3 and 6 months post-ezetimibe therapy, respectively. There were no significant differences in high-density lipoprotein cholesterol, renal function, proteinuria, creatine kinase, amylase, liver function, body mass index, or drug levels. There were no adverse drug reactions that mandated treatment withdrawal. When combined with statin therapy ezetimibe seemed to be a safe and effective treatment for uncontrolled dyslipidemia among renal transplant patients.
