The cellular events mediating the pleiotropic actions of portal vein glucose (PoG) delivery on hepatic glucose disposition have not been clearly defined. Likewise, the molecular defects associated with postprandial hyperglycemia and impaired hepatic glucose uptake (HGU) following consumption of a high-fat, high-fructose diet (HFFD) are unknown. Our goal was to identify hepatocellular changes el...

BACKGROUND Postprandial hyperinsulinemia, hyperglycemia, and insulin resistance increase the risk of type 2 diabetes (T2D) and cardiovascular disease mortality. Postprandial hyperinsulinemia and hyperglycemia also occur in metabolically healthy subjects consuming high-carbohydrate diets particularly after evening meals and when carbohydrate loads follow acute exercise. We hypothesized the invol...

OBJECTIVE Recent progress suggests that exenatide, a mimetic of glucagon-like peptide-1 (GLP-1), might lower glycemia independent of increased beta-cell response or reduced gastrointestinal motility. We aimed to investigate whether exenatide stimulates glucose turnover directly in insulin-responsive tissues dependent or independent of insulinemia. RESEARCH DESIGN AND METHODS An intraportal gl...

BACKGROUND This study used data from different sources to identify the extent of the unmet need for postprandial glycemic control in patients with type 2 diabetes mellitus (T2DM) after the initiation of basal insulin therapy in Europe, Asia Pacific, the United States, and Latin America. METHODS Different levels of evidence were used as available for each country/region, with data extracted fr...

BACKGROUND Postprandial hyperglycemia plays an important role in the pathogenesis of coronary artery disease and cardiovascular events. Serum 1,5-anhydroglucitol (1,5-AG) levels are known to be a clinical marker of postprandial hyperglycemia. However, the impact of 1,5-AG level on cardiovascular events has not been fully investigated. METHODS We enrolled 240 consecutive patients who had under...

OBJECTIVE To compare glycemic patterns by mode of therapy in children with type 1 diabetes mellitus using the Continuous Glucose Monitoring System (CGMS). DESIGN Open randomized crossover comparing 3(1/2) months of multiple daily injections (MDI) and continuous subcutaneous insulin infusion (CSII). SETTING Tertiary care, university-affiliated medical center. Patients Twenty-three children a...

Although a conventional insulin regimen for type 1 diabetes with twice-daily insulin injections is effective in preventing postprandial blood glucose excursions, this treatment is limited by its inadequate control of fasting hyperglycemia. Alternatively, sustained basal hepatic insulin gene expression has been shown to result in fasting normoglycemia in type 1 diabetic rats, although the treate...

Several combination therapies have been tried for treating of type 2 diabetes to control more effectively fasting hyperglycemia and postprandial hyperglycemia. In this study, we have examined the effects of combining a novel, selective, and competitive dipeptidyl peptidase IV (DPP-IV) inhibitor, 3-but-2-ynyl-5-methyl-2-piperazin-1-yl-3,5-dihydro-4H-imidazo[4,5-d]pyridazin-4-one tosylate (E3024)...

Dietary fiber improves hyperglycemia in patients with type 2 diabetes through its physicochemical properties and possible modulation of gut hormone secretion, such as glucagon-like peptide 1 (GLP-1). We assessed the effect of dietary fiber-enriched cereal flakes (DC) on postprandial hyperglycemia and gut hormone secretion in patients with type 2 diabetes. Thirteen participants ate isocaloric me...

The combination of a dipeptidyl peptidase-4 (DPP-4) inhibitor and a long-acting insulin analogue is widely used in clinical practice. However, some patients fail to achieve lower postprandial hyperglycemia. Mitiglinide, a short-acting insulinotropic sulfonylurea receptor ligand, is effective for postprandial hyperglycemia. Recently, it has been reported that the combination therapy of mitiglini...
