Seventeen TM patients with impaired glucose tolerance (IGT) or non-insulin dependent diabetes mellitus (NIDDM) and hyperinsulinism were treated for 12 months with acarbose (100 mg. orally with breakfast, lunch and evening meals). An improvement in glucose tolerance was observed in 2 out of 11 TM patients with IGT and in all TM patients with NIDDM. Acarbose does not appear to directly improve insulin resistance but may have an indirect effect delaying the absorption of glucose of complex carbohydrates and disaccharides. It may be concluded that acarbose may represent a useful first-line therapy for improving glycemic control in TM patients with abnormalities of glucose homeostasis and hyperinsulinism.

Metabolic and non metabolic cardiovascular risk factors tend to cluster in the same individual. The association of the cardiovascular risk factors is referred as metabolic syndrome (MS). This syndrome is associated with an increased risk of accelerated atherosclerosis and cardiovascular events. The cluster of cardiovascular risk factors of the MS includes: insulin resistance with or without glucose intolerance or diabetes, abdominal obesity, atherogenic dyslipidemia, elevated blood pressure, a proinflammatory and prothrombotic state. MS is one of the major issues in the management of cardiovascular disease because of its epidemic proportion and its impact on increasing risk of developing both cardiovascular disease and type 2 diabetes. The main therapeutic goal in the management of patients with the MS is to reduce risk for clinical cardiovascular events and to prevent type 2 diabetes. In particular, for individuals with established diabetes, risk factors management must be intensified to reduce their higher cardiovascular risk. Lifestyle changes have a critical role in the clinical management of the risk factors predisposing to MS, such as overweight/obesity, physical inactivity. A large body of evidence suggests the use of Metformin and Acarbose for the treatment of the syndrome as these drugs have consistently shown to reduce cardiovascular events and mortality. Most anti-hypertensive drugs have unfavorable metabolic profile while b-blockers, centrally acting agents and drugs targeting the renin angiotensin system should always be considered for the treatment of hypertension in patients with MS.

Dysglycaemic disease is one of the most important health issues facing the world in the 21st century. Patients with type 2 diabetes and individuals with prediabetes are at risk of developing macrovascular and microvascular complications. Long-term management strategies are therefore required that are effective at controlling dysglycaemia, well tolerated and, ideally, offer additional cardiovascular disease (CVD) risk-reduction benefits. The efficacy, safety and tolerability of the alpha-glucosidase inhibitor acarbose have been well-established in a wide range of patient populations in both clinical and community trials. In addition, acarbose has been shown to reduce cardiovascular complications in type 2 diabetes and prevent hypertension and CVD in individuals with impaired glucose tolerance (IGT). Acarbose has a very good safety profile and, owing to its straightforward, non-systemic mode of action, avoids most adverse events. The most common side-effects of acarbose are mild-to-moderate gastrointestinal complaints that subside as treatment continues. They can be minimised through the use of an appropriate stepwise dosing regimen and careful choice of diet. Acarbose is therefore a valuable option for the management of type 2 diabetes and, as the only oral antidiabetes agent approved for the treatment of prediabetes, can help to improve clinical management across the dysglycaemic disease continuum.

The metabolic syndrome (MS), a cluster of risk factors, such as obesity, hyperglycemia, hypertension and dyslipidemia, contributes to the development of cardio-vascular diseases and type 2 diabetes mellitus (DM2). Insulin resistance (IR) plays a key role in MS being strongly linked to abdominal visceral fat. Treatment for obese patients with MS should aim at improving IR, delaying the onset of DM2 and at reducing cardio-vascular risk. Weight loss, first therapeutic target, may be obtained through life-style modifications and anti-obesity drugs or bariatric surgery, at need. In these patients drug therapy is necessary if therapeutic life-style changes are not sufficient. Some drugs have adverse metabolic effects, therefore the therapeutic choices must be specific and rational. Metformin, Thiazolidinediones and Acarbose are anti-hyperglycemic drugs of choice: they reduce the incidence of DM2 and IR (or improve insulin sensitivity) and they decrease or stabilize the visceral adipose tissue mass (Thiazolidinediones increases subcutaneous fat only). Also Angiotensin II receptor blockers and Angiotensin-converting enzyme inhibitors reduce the incidence of DM2 and insulin resistance and they are first-line antihypertensive drugs in MS. Calcium channel blockers, Alpha-1 antagonists and Alpha-2 agonists drugs are metabolically neutral and slight weight gains are related to the hydro-sodium retention. Beta-blockers and Diuretics, except for Indapamide and Anti-aldosterone drugs, can reduce insulin sensitivity, impair lipid profile and increase DM2 incidence; they are not first-line therapy yet they are necessary in selected cases only. Statins, Fibrates and omega-3 Fatty acids are indicated to normalize dyslipidemia. Low doses of acetylsalicylic acid are also recommended.

The severity of the type 2 diabetes epidemic is widely acknowledged. Demographic, social, and cultural changes around the world are driving a dramatic increase in the prevalence of type 2 diabetes. Consequently, there is increasing interest in defining the target population and developing strategies for preventing or delaying the disease. Impaired glucose tolerance (IGT), an asymptomatic condition early in the disease continuum of dysglycemia, is the best target for intervention, as it is a strong predictor for the development of both type 2 diabetes and cardiovascular disease (CVD). Identifying individuals likely to have IGT using risk-prediction tools is simple and cost-effective; diagnosis can be confirmed with an oral glucose tolerance test. Numerous trials have examined the benefits of intervention in IGT populations. Lifestyle modification and some pharmacologic therapies, such as acarbose, have been shown to significantly reduce disease progression. Acarbose therapy has also been associated with significant reductions in cardiovascular events and new cases of hypertension. Trials assessing the potential preventive effects of various therapies are ongoing, but current evidence confirms that early intervention in individuals with IGT can reduce the risks of type 2 diabetes and CVD. Identification of high-risk individuals should therefore be standard in general practice and, if IGT is diagnosed, therapeutic intervention should be initiated promptly.

Postprandial lipemia has emerged as an independent risk factor for coronary artery disease. In this systematic review we examined the effect of the medications used for the management of diabetes, obesity and dyslipidemia on postprandial lipemia. It should be mentioned that no standardization exists for a test meal and for the duration of observation postprandially to allow for direct comparisons between the published studies. Type 2 diabetes mellitus and insulin resistance are associated with enhanced postprandial lipemia. Insulin is effective in reducing both fasting and post prandial total triglyceride levels as well as triglycerides contained in the triglyceride-rich lipoprotein sub-fractions. Additionally, the newer rapid-acting insulin analogues seem to be more effective in the reduction of postprandial lipemia than the short-acting human insulins. Acarbose ameliorates postprandial lipemia and reduces the atherogenic chylomicron and very low density lipoprotein remnants. Metformin reduces both fasting and postprandial triglyceridemia, fasting and post-prandial free fatty acids and may increase the concentrations of the high density lipoprotein cholesterol. Sulfonylureas reduce fasting and postprandial triglyceride levels while data on the effect on high density lipoprotein levels are inconsistent. The effect of meglitinides on postprandial lipid metabolism is neutral. Rosiglitazone decreases fasting and postprandial free fatty acids but has no significant effect on fasting and postprandial triglycerides. Pioglitazone has additional beneficial effects on lipid metabolism because it reduces postprandial free fatty acids, fasting and postprandial triglycerides and increases high density lipoprotein cholesterol levels. Limited available data suggest that glucagon-like peptide-1 analogues and vildagliptin reduce postprandial lipemia through reduction of intestinally-derived triglycerides. No data exist on the effect of sitagliptin on postprandial lipemia. Orlistat improves postprandial lipemia by reducing the absorption of the dietary fat; no data exist on the effect of sibutramine and rimonabant on the metabolism of lipids in the postprandial state.

Platelet-derived microparticles (PDMP), selectins, and adiponectin play an important role in the development of atherosclerosis in diabetes. Acarbose has been shown to have a beneficial effect on postprandial hyperglycemia in diabetic patients. However, its influence on PDMP, selectins, and adiponectin in these patients is poorly understood. We investigated the effect of acarbose on circulating levels of PDMP, selectins, and adiponectin in patients with type 2 diabetes. Acarbose (300 mg/day) was administered for 3 months. Levels of PDMP, sP-selectin, sL-selectin, and adiponectin were measured by ELISA at baseline and after 1 and 3 months of treatment. The levels of PDMP, sP-selectin, and sL-selectin were higher in diabetic patients than in hypertensive patients (PDMP; 35.1 +/- 34.2 vs. 53.3 +/- 56.7 U/ml, P < 0.05: sP-selectin; 134 +/- 52 vs. 235 +/- 70 ng/dl, P < 0.01: sL-selectin; 569 +/- 183 vs. 805 +/- 146 ng/ml, P < 0.05), while there were no significant differences between hypertensive and hyperlipidemic patients. Before acarbose treatment, the adiponectin level of diabetic patients was lower than that of hypertensive patients. Acarbose therapy significantly decreased the plasma PDMP level relative to baseline. Acarbose also caused a significant decrease of sP-selectin and sL-selectin. On the other hand, acarbose therapy led to a significant increase of adiponectin after 3 months of administration compared with baseline (adiponectin: diabetes versus hypertension, 3.61 +/- 1.23 vs. 5.87 +/- 1.92 microg/ml, P < 0.05; diabetes versus controls, 2.81 +/- 0.95 vs. 6.13 +/- 1.24 microg/ml, P < 0.01). Twelve of the 30 diabetic patients had a history of thrombotic complications. Furthermore, the reduction of PDMP and selectins during acarbose therapy was significantly greater in the thrombotic group (12 of 30) than in the nonthrombotic group (18 of 30) of diabetic patients. Acarbose may be beneficial for primary prevention of atherothrombosis in patients with type 2 diabetes. However, it requires a large clinical trial to test this hypothesis.

So far little is known about how the antidiabetic drugs acting at the level of gastrointestinal mucosa may affect immune and cellular response to food intake. The following study investigated the association between acarbose treatment and postprandial metabolism, immune- and inflammatory activity in patients with early type 2 diabetes: The Acarbose action on low grade Inflammation and Immune response in type 2 Diabetes on Atherosclerosis risk (AIIDA) study. Middle-aged patients (n=87) with early type 2 diabetes (2 h-plasma-glucose >or=11.1 mmol/l and/or HbA1c >or=6.5%) and sub-clinical inflammation (leucocytes >or=6.2 GPt/l and/or hsCRP >or=1.0 mg/l) underwent a mixed meal load (527 kcal). Metabolic parameters and markers of subclinical inflammation were measured at fasting (0'), 2 h-postprandial (2-hpp) and 4-hpp before and after 20 weeks of treatment with acarbose or placebo. Leukocytes and lymphocytes excursion after 20 weeks of treatment was significantly reduced with acarbose 4 h after testmeal [GPt/l] (7.5 vs. 7; p<0.05; and 2.29 vs. 2.14; p<0.05, respectively). Acarbose had only marginal effects on pp glucose, FFA, triglycerides, and insulin excursion. Biomarkers of inflammation (hsCRP, MBL, and PAI1) were not affected by acarbose. Multivariate analysis reveals only baseline leukocytes and of acarbose as independent determinant of 4-h leucocytes excursion. Postprandial metabolic and inflammatory parameters were strongly interrelated. These results suggest pleiotropic effects of acarbose, which may contribute to its vasoprotective potentials.

Glucagon-like peptide-1 (GLP-1), an incretin hormone, is essential for the regulation of insulin secretion and glucose homeostasis. GLP-1 is rapidly degraded by dipeptidyl peptidase 4 (DPP4); therefore, DPP4 inhibitors are considered to be a novel class of oral antihyperglycemic agents. These agents are currently under development as treatments for type 2 diabetes. Normally, oral glucose tolerance tests are used for evalating glucose-lowering efficacy, but the augmentation of active GLP-1 via DPP4 inhibition in this test was transient. It has been proposed that the secretion of GLP-1 is regulated by the rate of entry of nutrients into the small intestine; therefore, we have established the new meal tolerance test method using solid diet. This model allows for the continuous monitoring of active GLP-1 secretion after food intake. ASP4000 is an orally effective inhibitor of DPP4 that greatly augments meal-stimulated circulating levels of active GLP-1 constitutively and improves hyperglycemia. Acarbose improved glucose tolerance in the test to a degree similar to that of the DPP4 inhibitor. Our new meal tolerance test is useful for evaluating postprandial hyperglycemia and could be an excellent model for studying the secretion of active GLP-1 via the inhibition of DPP4.

The alpha-glucosidase inhibitor acarbose is administered to control blood glucose levels in type 2 diabetic patients and, in several countries, in those with impaired glucose tolerance. The efficacy and safety of the drug has been well established in these patient populations. Acarbose shows no weakening of efficacy in long-term diabetes treatment, reduces the development of type 2 diabetes in those with impaired glucose tolerance, and also appears to reduce the risk of cardiovascular disease. The underlying mechanisms of its effect on the risk of developing macrovascular complications have still to be elucidated. The mode of action of acarbose, which precedes all other metabolic processes involved in blood glucose regulation, inhibits high increases in postprandial blood glucose. Due to this early mode of action, acarbose also modifies insulin and proinsulin secretion which are both involved in ss-cell dysfunction and insulin resistance and may be independent risk factors for cardiovascular mortality. Based on the literature available the present state of knowledge on insulin and proinsulin as risk factors for cardiovascular mortality is reviewed as well as the effect of acarbose on the regulation of the ss-cells as monotherapy and in combination regimens. Possible associated interactions with the cardiovascular system are identified.
