The objective of the present study was to determine the effects that hemolysis, lipemia, bilirubinemia, and anticoagulants might have on the most commonly used assays for C-reactive protein and serum amyloid A, and determination of ceruloplasmin values in dogs. Solutions of hemoglobin, lipid, and bilirubin were added to serum aliquots. Additionally, serum and plasma samples with different anticoagulants (heparin, EDTA, and citrate) were obtained from healthy dogs. Hemolysis, lipemia, and hyperbilirubinemia interfered significantly with the C-reactive protein and ceruloplasmin results, but not with those for the serum amyloid A assay. The use of anticoagulants produced significant changes in the results for the assays tested. However, the magnitude of the differences caused by the interfering substances does not appear to have an important impact on the clinical interpretation of the tests.

In type 2 diabetics, the progression of atherosclerosis is more rapid than the general population and 80% of these patients will die of an atherosclerotic event. Since in these patients hyperglycemia per se confers increased risk for cardiovascular disease (CVD), the presence of even borderline-high-risk LDL-C signals the need for more aggressive LDL-lowering therapy. Most of the lipid lowering agents, currently in use in the treatment of dyslipidemia in type 2 diabetics, have a host of side effects. In contrast, dietary tocotrienols are Vitamin E and have effective lipid lowering property in addition to their potent antioxidant activity. In this study, we have investigated the therapeutic impacts of tocotrienols on serum and lipoprotein lipid levels in type 2 diabetic patients. Based on known tocotrienol rich fraction (TRF)-mediated decrease on elevated blood glucose and glycated hemoglobin A(1C) (HbA(1C)) in diabetic rats, we have also investigated the effect of TRF on these parameters. A randomized, double blind, placebo-controlled design involving 19 type 2 diabetic subjects with hyperlipidemia was used. After 60 days of TRF treatment, subjects showed an average decline of 23, 30, and 42% in serum total lipids, TC, and LDL-C, respectively. The goal in type 2 diabetics is to reduce LDL-C levels < or = 100mg/dl. In the present investigation tocotrienols mediated a reduction of LDL-C from an average of 179 mg/dl to 104 mg/dl. However, hypoglycemic effect of TRF was not observed in these patients because they were glycemically stable and their glucose and HbA(1) levels were close to normal values. In conclusion, daily intake of dietary TRF by type 2 diabetics will be useful in the prevention and treatment of hyperlipidemia and atherogenesis.

We prospectively evaluated the efficacy and safety of a 24-month course of intermittent intravenous cyclophosphamide (IC) therapy for children suffering from lupus nephritis soon after the diagnosis of systemic lupus erythematosus (SLE) was made. Eight children with severe lupus nephritis were treated with IC monthly for 6 months and then every 3 months, totaling 24 months. The repeated measurements of sequential serological parameters of lupus nephritis, monitored over the course of the study, were analyzed statistically. The urine creatinine clearance rate (Ccr), the 24-h urine protein excretion, and the serum creatinine level significantly improved (p<0.05) after 6, 9 and 12 months of treatment, respectively. The serum C3, C4, albumin, and triglyceride level, the hemoglobin level, and the erythrocyte sedimentation rate significantly improved (p<0.05) 1 month after treatment. The IC appeared to elicit a significant effect (p<0.05) upon the mean leukocyte and neutrophil counts but had no effect (p>0.05) on the platelet count. The lymphocyte count decreased (p<0.05) during the first six monthly IC, whereas the lymphocyte count returned to the baseline level during the quarterly IC events. From a total of 96 IC doses given to those SLE patients, severe myelotoxicity occurred in one patient when lymphocyte count declined to 98 mm(-3); however, no sign of clinical infection was observed. The daily steroid dosage can be tapered rapidly, and the SLE-associated hyperlipidemia resolved parallel to the resolution of the acute lupus nephritis. We concluded that the efficacy of a 24-month IC course for a child suffering from lupus nephritis is significant.

The effect of L-arginine and spermidine on hemoglobin glycation and lipid peroxidation in serum of normal and diabetic rats was studied. Five groups of 40 rats were studied during 20 days and compared with a control group (Group I) that consisted of normal rats (N = 6) not treated with L-arginine or spermidine. Group II, diabetic rats (alloxan 120 mg/kg, i.p. at the day 0 and alloxan 60 mg/kg, i.p. at the day 10) were considered as diabetic control. Group III, diabetic rats treated with 10 mM L-arginine (i.p.). Group IV, diabetic rats treated with 10 microM spermidine (i.p.). Group V, normal rats treated with 10 mM L-arginine (i.p.). Group VI, normal rats treated with 10 microM spermidine (i.p.). The rats of each group were divided in subgroups of four each. Rats were anesthetized and blood was taken from aorta to determine glucose, triglycerides (TGs), total cholesterol (TC), low- and high-density lipoproteins (LDL and HDL), glycated hemoglobin (HbA(1C)), and thiobarbituric acid-reactive substances (TBARS). We observed that the alloxan concentrations used in this study reproduced the clinical manifestations of disease including hyperglycemia (from 116 +/- 7 mg/dl to 435 +/- 80 mg/dl) in 96 hours. As a consequence the levels of TGs, TC, LDL, TBARS, and HbA(1C) were increased, whereas HDL diminished. HbA(1C) concentration was significantly correlated with the concentration of TBARS. The L-arginine and spermidine injection tended to normalize the glycemia from 24 hours, similarly, hyperlipidemia, TBARS, and HbA(1C). From these results, we conclude that l-arginine and spermidine exerted an inhibitory effect of hemoglobin glycation and lipid peroxidation in vivo, which may be relevant in preventing diabetic complications.

The Wistar Diabetic Fatty rat (WDF fafa) is a congenic strain of the Wistar Kyoto rat. Studies using blood glucose reveal that only fatty male (not female) WDF rats spontaneously develop hyperglycemia when fed a stock diet. Blood glucose values have not provided consistent results for evaluation of glycemic status in fatty male WDF rats. Zucker fatty (fafa) rats, while sharing the fa gene and the development of hyperinsulinemia and hyperlipemia, do not spontaneously become hyperglycemic. In order to examine strain differences and the effects of age on long-term average glycemic status in WDF and Zucker rats, glycated hemoglobin (GHb) was analyzed. Glycated hemoglobin was measured in male lean and obese WDF and Zucker rats at 2, 3, 6, and 12 months of age. Nonfasted plasma glucose was measured in male lean and obese WDF rats at 2, 3, 6, and 12 months of age and in lean and obese Zucker rats at 3, 6, and 12 months of age. Plasma insulin was measured in lean and obese WDF and Zucker rats at 3, 6, and 12 months of age. Obese WDF rats had significantly elevated GHb compared to lean controls at 3, 6, and 12 months of age. Glycated hemoglobin was substantially above the normal range (3.8-6.5%) at 3 months of age (14.1%). Glycated hemoglobin significantly declined in the obese WDF rats between 6 and 12 months of age. Nonfasted plasma glucose was significantly elevated in the obese WDF rats at 3 months (14.1 +/- 2.1 mM/L) and 6 months of age (16.2 +/- 2.3 mM/L) compared to lean controls. At 12 months of age there was no difference in plasma glucose between obese and lean WDF rats. Obese and lean Zucker rats had similar levels of GHb and plasma glucose at all ages. In conclusion, GHb provides more integrated data for classifying disease status of WDF rats and evaluation of potential long-term complications associated with hyperglycemia.

The glycosylated hemoglobin (HbA(1c)) goal in patients with type 2 diabetes mellitus should be to achieve as low a value as can be obtained without causing significant or frequent hypoglycemia. This is best achieved by utilizing agents that lower glucose levels without causing hypoglycemia (thiazolidinediones and metformin). To maintain these low HbA(1c) values and avoid the utilization of insulin secretagogues or insulin, which are associated with hypoglycemia and suboptimal dosing leading to higher HbA(1c) values, drugs that maintain or improve pancreatic beta-cell function (thiazolidinediones and possibly incretin-based therapies) should be utilized. Restoration of first-phase insulin release, as has been shown with thiazolidinediones, will not only improve postprandial hyperglycemia but will also improve postprandial hyperlipidemia, both of which will decrease cardiac risk. Utilizing small doses of two drugs will also result in a decreased incidence of adverse effects compared with a large dose of a single drug. The use of fixed-dose combination oral antihyperglycemics will not only improve compliance but will often decrease costs compared with individual component dual therapy.

Postprandial hyperglycemia and hyperlipidemia are considered risk factors for cardiovascular disease. This study was designed to elucidate whether improving the postprandial state by voglibose, an alpha-glucosidase inhibitor, leads to the reduction of oxidative stress markers and soluble adhesion molecules in obese type 2 diabetic patients. A total of 30 Japanese obese type 2 diabetic patients were randomly assigned and treated for 3 weeks with either diet alone (the control group) or diet plus voglibose (0.9 mg daily) (the voglibose group) (n=15 each). Analysis of the diurnal metabolic profiles revealed a significant reduction of postprandial hyperglycemia and hyperlipidemia in the voglibose group relative to the control group (P<.05), despite the similar improvement in body mass index and hemoglobin A(1c) in both groups. Voglibose also decreased significantly the plasma levels of soluble intercellular adhesion molecule 1 and urinary excretion of 8-iso-prostaglandin F(2)alpha and 8-hydroxydeoxyguanosine (P<.01) and C-reactive protein (P<.05) relative to the control group. In conclusion, this study represents the first demonstration that voglibose reduces oxidative stress generation and soluble intercellular adhesion molecule 1 in parallel with the reduction of postprandial hyperglycemia and hyperlipidemia in obese type 2 diabetic patients.

Glycosylated hemoglobin (HbA1c) is a marker of evaluation of long-term glycemic control in diabetic patients and predicts risks for the development and/or progression of diabetic complications. Glycosylation process depends on the exposure to glucose, so on the half-life of erythrocyte. It was demonstrated, however that metabolic control concerning the last 90-120 days had only a 10% effect on the result of HbAlc; mean blood glucose of the last 30 days contributes for 50% of HbA1c value. Blood glucose value in the afternoon and in the evening better correlate with HbA1c levels if compared with blood glucose values in the morning. It is important to know that there may be, in the evaluation of HbAlc, interference in the dosage, due to a condition of uremia, hyperlipemia, bad conservation and hemolysis of the sample, increase of leucocytes and presence of anomalous hemoglobins. Moreover the use of different methods, the lack of a common calibration concerning the same methods and the variability of instrumentation do not make reproducible results yet, in different laboratories.

Cardiovascular disease causes the deaths of up to 50% of renal transplant recipients who have a functioning graft. As in other states of chronic kidney disease, both overload cardiomyopathy (chronic heart failure and left ventricular hypertrophy) and ischemic heart disease are evident; age and gender are important risk factors for both of these disorders. Potentially treatable risk factors include smoking, hyperlipidemia, diabetes and hypertension for ischemic heart disease, and anemia, hypertension and diabetes for cardiomyopathy. Although definitive evidence on the effectiveness of interventions is lacking, it seems reasonable to treat renal transplant recipients as patients at the highest risk of cardiovascular disease. Aggressive targeting of lifestyle factors, blood pressure, cholesterol and sugar regulation is likely to have a major impact on patient and graft survival and should be initiated well before transplantation. Maintenance of hemoglobin with erythropoietic agents is controversial but might improve quality of life. Although immunosuppressive agents have distinct effects on cardiovascular risk factors, the impact on outcomes is impossible to predict on the basis of current data, and no firm recommendations can be made.

Colestimide is a new anion-exchange resin used to lower serum cholesterol in Japan. Because of its excellent compliance, colestimide can replace cholestyramine. To clarify the effect of colestimide on glycemic controls, colestimide (3 g/day) or pravastatin (10 mg) was given orally to patients with type 2 diabetes treated with oral hypoglycemic agents or insulin who had low-density lipoprotein (LDL) cholesterol levels exceeding 3.6 mmol/l. In the colestimide groups, fasting plasma glucose concentrations had decreased significantly from 8.5 +/- 1.4 to 7.7 +/- 1.5 mmol/l at 3 months (P<0.05), as had glycated hemoglobin (HbA1c) from 7.7 +/- 0.7% to 6.8 +/- 0.5%, for an 8% reduction (P<0.01). Fasting plasma glucose and HbA1c did not change in the pravastatin group. Total cholesterol and LDL-cholesterol decreased significantly (P<0.01) with either medication, with similar reduction rates for both drugs. Doses of oral hypoglycemic agents and insulin did not change during the study, and body weight remained stable. Considering that patients with type 2 diabetes often have hyperlipidemia, colestimide therapy may have a clinically useful dual action in such patients.
