The prevalence and significance of microalbuminuria in hypertensive patients with impaired fasting glucose (IFG) has received very little attention. A total of 10,320 hypertensive patients who attended primary care centers were enrolled in this study, and the final analysis was done in 7625 patients: 1459 without IFG (plasma glucose <100 mg/dl), 3010 with IFG (plasma glucose > or =100 mg/dl and <126 mg/dl), and 3156 with type 2 diabetes (plasma glucose >126 mg/dl). Microalbuminuria was determined using the Micro Albustix reactive strip from Bayer (high urinary albumin excretion [UAE]: Albumin/creatinine ratio > or =3.4 mg/mmol). The proportion of patients with high UAE was 39.4, 48.3, and 65.6%, respectively, in the three groups (P < 0.01 for the trend). The differences in UAE between the group with IFG and the group with normal fasting glucose persisted after adjustment for age, gender, systolic BP, fasting plasma glucose, and cardiovascular comorbidity (odds ratio 1.74; 95% confidence interval 1.08 to 2.80). Hypertensive patients with IFG and high UAE showed a higher prevalence of ischemic heart disease, cardiac insufficiency, left ventricular hypertrophy, atrial fibrillation, and renal insufficiency than the group with normal UAE. Global prevalence of cardiovascular conditions was 30.4% in the group with high UAE compared with 21.4% in the group with normal UAE (odds ratio 1.60; 95% confidence interval 1.31 to 1.95). It is concluded that almost half of hypertensive patients with IFG have high UAE and a higher prevalence of associated cardiovascular involvement and renal insufficiency.

The objective of this study was to assess the relationship between urinary albumin excretion (UAE) and GF across the spectrum of the glucose metabolism abnormalities in a large population of patients with hypertension. The Microaluminuria en Pacientes con Glucemia Basal Alterada (MAGAL) is a multicenter, cross-sectional study that was carried out by 1723 primary care physicians. A total of 6227 patients with essential hypertension (in three groups: [1] normal fasting glucose <100 mg/dl, [2] impaired fasting glucose > or =100 to 126 mg/dl, and [3] type 2 diabetes) were analyzed in this substudy. GFR was estimated by using the Modification of Diet in Renal Disease (MDRD) abbreviated equation. A single first-morning urine albumin/creatinine ratio was measured using Bayer reagent strip Microalbustix, a semiquantitative method. Abnormal UAE was defined as an albumin/creatinine ratio > or =3.4 mg/mmol (equivalent to > or =30 mg/g). The prevalence of abnormal UAE, > or =3.4 mg/mmol, increased across the spectrum of glucose abnormalities: 39.7, 46.2, 48.6, and 65.6% for normoglycemic, low-range, and high-range impaired fasting glucose and diabetes, respectively. UAE was positively related to SBP (P = 0.003) and inversely to GFR (P < 0.001). Renal insufficiency (GFR <60 ml/min per 1.73 m2) was present in 21.8% of the patients, more frequently older patients, women, and those with diabetes. The factors that were related to renal insufficiency were UAE > or =3.4 mg/mmol (odds ratio 1.86; 95% confidence interval 1.60 to 2.17) and diabetes (odds ratio 1.62; 95% confidence interval 1.29 to 2.04). There is a close relationship between abnormal UAE and renal insufficiency in essential hypertension. This is more marked in patients with diabetes and moderate in patients with high-range impaired fasting glucose.

In the population of hemodialysis patients the risk of ischemic heart disease and morbidity related to it, is considerably higher than in general population. In the group of elderly hemodialysed patients and in patients with diabetes this risk is even higher Additional risk factors of cardiovascular disease are those specific for renal insufficiency, including the presence of arterio-venous fistula, which is believed to be an independent risk factor for cardiovascular disease through the promotion of hyperkinetic circulation. In the study the impact of the arterio-venous fistula on heart function in Doppler USG in the group of 16 elderly hemodialysis patients (aged 79, 4 +/- 5,4), 10 diabetics with type 2 diabetes (aged 63,2 +/- 10,4) and 7 hemodialysis patients younger and without diabetes was examined. In all patients arterio-venous fistula was created on the forearm from native vessels. The following hemodynamic USG parameters of heart function were assessed: ejection fraction (EF), shortening fraction (FS), stroke volume (SV) and cardiac output (CO). We conclude that impact of native arterio-venous fistula created on forearm on circulation in the group of elderly and diabetic patients is of the same magnitude as in the group of younger, non diabetic patients.

The aim of the study was to assess skeletal status in diabetic and nondiabetic subjects with end-stage renal disease (ESRD). One hundred twenty-three patients with ESRD (57 patients with diabetes: 9 type 1 and 48 type 2) and 66 nondiabetic patients were evaluated. Control group comprised 1541 subjects (614 males and 927 females). Diabetes and/or renal insufficiency was the only reason of bone disease and, in control group, no factors known to influence bone metabolism (chronic diseases or prolonged medications) were noted. Skeletal status was evaluated by quantitative ultrasound measurements at the hand phalanges using DBM 1200 (IGEA, Carpi, Italy), which measures amplitude-dependent speed of sound (Ad-SoS [m/s]). Because of some differences in mean age in subgroups of patients and controls, comparisons were performed using values of Z-score. In all diabetic patients, Z-score was significantly higher compared with nondiabetics (p < 0.05). In all type 1 diabetes patients, Z-score was significantly lower than in all nondiabetic patients (p < 0.05) and in patients with type 2 diabetes (p < 0.001). Z-score was also significantly lower in type 2 diabetics than in nondiabetic females (p < 0.00001) but did not differ in males. Comparisons between Z-scores in controls and patients showed that Z-score in nondiabetic females was significantly lower than in female controls (p < 0.000001), and in nondiabetic males--diabetic type 2 males as well as females--Z-score did not differ vs. results in adequate control group. Z-score was significantly lower in patients with diabetes type 1 vs. all controls (p < 0.001). Correlation analysis showed in all nondiabetic patients that Z-score was negatively affected by duration time of dialysis (r = -0.37, p < 0.01) and parathyroid hormone (PTH) serum level (r = -0.35, p < 0.01). In patients with type 1 diabetes, only PTH influenced significantly Z-score (r = -0.76, p < 0.05) and, in patients with type 2 diabetes, no significant correlations were obtained. Subjects with type 1 diabetes seemed to be sensitive for skeletal disturbances in a course of renal insufficiency, whereas subjects with type 2 diabetes did not show such skeletal pathology as shown by ultrasound measurements at hand phalanges.

Cardiovascular diseases are directly affected by arterial hypertension. When associated with diabetes mellitus, the potential deleterious effects are well amplified. Both conditions play a central role in the pathogenesis of coronary artery disease, heart failure, stroke, and renal insufficiency. Prevalence of hypertension is much higher among diabetic than non-diabetic patients, and the hypertensive patient is more likely to develop type 2 diabetes. Current international guidelines recommend aggressive reductions in blood pressure (BP) in hypertensive patients with additional risk factors, including cardiovascular risk factors, and emphasize the relevance of intensive reduction in patients with diabetes mellitus; a goal of 130/80 mm Hg is required. To achieve BP target a combination of antihypertensives will be needed, and the use of long-acting drugs that are able to provide 24-hour efficacy with a once-daily dosing confers the noteworthy advantages of compliance improvement and BP variation lessening. Lower dosages of the individual treatments of the combination therapy can be administered for the same antihypertensive efficiency as that attained with high dosages of monotherapy. Angiotensin-converting enzyme inhibitors and calcium-channel blockers as a combination have theoretically compelling advantages for vessel homeostasis. Trandolapril/verapamil sustained release combination has showed beneficial effects on cardiac and renal systems as well as its antihypertensive efficacy, with no metabolic disturbances. This combination can be considered as an effective therapy for the diabetic hypertensive population.

The incidence and prevalence of end-stage renal disease (ESRD) is increasing. Diabetic nephropathy has increased in absolute numbers and as a proportion of patients with ESRD. This is almost totally accounted for by the explosive outbreak of Type 2 diabetes mellitus (DM). The world is in the midst of an epidemic of Type 2 DM and hence this trend is likely to continue for some more time. The contribution of glomerulonephritis as a proportion of patients with chronic renal failure (CRF) has declined due to increase in other causes such as diabetes. The annual incidence of IgA nephropathy, which is also a very common cause of renal insufficiency, has not changed. The incidence of focal segmental glomerulosclerosis is increasing while that of membranoproliferative glomerulonephritis is decreasing. Peak incidence of ESRD due to hypertension has shifted to a higher age-group. The proportion of renovascular disease as a cause of ESRD is also increasing. Human immunodeficiency virus associated nephropathy is the third leading cause of ESRD in African-Americans aged 20-64 years. Other diseases such as analgesic nephropathy and lead nephropathy are slowly disappearing. The significance of elevated body lead in patients with varying degrees of renal insufficiency requires further evaluation. The incidence of CRF is significantly higher in the elderly and hence there is a "graying" of CRF population. Census projections show that this trend will continue into the foreseeable future. The incidence and prevalence of ESRD vary between different populations, countries and within countries. The reason for the variations requires further study.

Metformin is a biguanide used in the treatment of obese adults with type 2 diabetes mellitus; metformin decreases mortality by 36% in comparison to conventional treatment. Metformin administration has certain contraindications that, when ignored, especially in the case of acute renal insufficiency, leads to the accumulation of the drug and consequent lactic acidosis that can be fatal. We present 6 patients with acute renal insufficiency that experienced extreme acute metabolic acidosis (pH <6.90 and bicarbonate <5 mEq/l) and increased anion gap while receiving metformin for the treatment of diabetes. Serum lactic acid, only evaluated in the 4 patients that survived, was high. Two patients died after cardiac arrest that could have been avoided. In conclusion, lactic acidosis appearing during metformin treatment for diabetes requires rapid diagnosis and treatment to enable the drug to be withdrawn and prolonged continuous hemofiltration or hemodialysis with bicarbonate to be initiated.

Hyperuricemia has been reported to be associated with increased risk of renal insufficiency as well as cardiovascular events. The aim of this study was to evaluate the relationships between serum uric acid concentration and degree of urinary albumin excretion as well as markers of subclinical atherosclerosis in men with type 2 diabetes mellitus. Serum uric acid concentrations were measured in 343 men with type 2 diabetes mellitus. We then evaluated relationships of serum uric acid concentrations to degree of urinary albumin excretion as well as to major cardiovascular risk factors, including age, blood pressure, serum lipid concentration, and glycemic control (hemoglobin A1c). The relationships between serum uric acid concentration and pulse wave velocity or ankle-brachial index (n=236) and between serum uric acid concentration and carotid intima-media thickness or plaque score (n=125) were investigated additionally in a subgroup of patients. Serum uric acid concentration correlated positively with logarithm of urinary albumin excretion (r=0.302, P<.0001). Positive correlation was found between serum uric acid concentration and intima-media thickness (r=0.233, P=.0087), whereas inverse correlation was found between serum uric acid concentration and ankle-brachial index (r=-0.150, P=.0207). Multiple regression analysis demonstrated that serum uric acid concentration (beta=.281, P<.0001), duration of diabetes (beta=.253, P<.0001), hemoglobin A1c (beta=.166, P=.0034), serum triglyceride concentration (beta=.125, P=.0472), and systolic blood pressure (beta=.275, P=.0013) were independent determinants of logarithm of urinary albumin excretion. In conclusion, serum uric acid concentration is associated with microalbuminuria and subclinical atherosclerosis in men with type 2 diabetes mellitus.

Type 2 diabetes mellitus is one of the leading causes of end-stage renal disease in the Western world. Smoking can also be seen as a powerful agent, although often underrated, able to induce renal damage and microvascular dysfunction via several different mechanisms, which often overlap with those of diabetic disease, and in concert may eventually worsen the renal redox homeostasis. As a result of this, the association of diabetes with smoking may favor the onset and/or the progression of renal insufficiency toward renal failure, and such a conclusion is supported by an array of epidemiological and physiopathological studies. Consequently, smoking prevention and cessation programs must be strongly encouraged not only to reduce the cardiovascular risk, but also to avoid the deterioration of renal function among diabetic patients.

Diabetes mellitus is a frequent cause of renal insufficiency. Renal insufficiency is associated with both haemorrhagic manifestations primarily caused by platelet functional disorders, and states of hypercoagulation resulting from significant hyperfibrinogenemia. Fibrinolysis is either increased or, often, decreased. Changes in haemostasis in renal insufficiency have been dealt with by many authors in relevant literature. However, the final stage of renal insufficiency is rather dominated by haemorrhagic diathesis. It is manifested by skin haemorrhage, mucosal manifestations, but also by retroperitoneal and cerebral haemorrhage. The main cause of a haemorrhagic condition is platelet dysfunction combined with anticoagulation and antiplatelet therapy which is used in dialysis. Platelet function disorders are provoked by acquired thrombocytopaenia and result in a disorder in the interaction between the blood vessel wall and the platelet. Dialysis suppresses platelet abnormalities only temporarily by suppressing uremic toxins provoking platelet disorders. On the other hand, dialysis may cause prothrombotic activity. Changes in haemostasis in type 2 diabetes mellitus form part of the insulin resistance syndrome and induce prothrombotic condition due to decreased fibrinolysis.
