Comparison of the efficacy and safety of once-daily insulin degludec/insulin aspart (IDegAsp) and long-acting second-generation basal insulin (insulin degludec and insulin glargine 300 units/mL) in insulin-naïve Japanese adults with type 2 diabetes: a pilot, randomized, controlled study.

To examine the efficacy and safety of once-daily insulin degludec/insulin aspart (IDegAsp) or once-daily second-generation basal insulin analogs (insulin degludec and insulin glargine 300 units/mL) in insulin-naïve Japanese adults with type 2 diabetes in routine clinical practice. A 12-week multicenter, open-label, randomized, pilot study was performed in 52 subjects with type 2 diabetes treated with oral antidiabetic drugs (OADs). Subjects were randomized to once-daily IDegAsp (n = 26) or basal insulin (n = 26).

A 1-year, prospective, observational study of Japanese outpatients with type 1 and type 2 diabetes switching from insulin glargine or detemir to insulin degludec in basal-bolus insulin therapy (Kumamoto Insulin Degludec Observational study).

Aims/introduction: The aim of the present prospective observational study was to assess long-term efficacy and safety of insulin degludec as a part of a basal-bolus therapy for Japanese patients with type 1 or type 2 diabetes in routine clinical practice.

Materials And Methods: In the present study, 93 type 1 diabetes patients and 135 type 2 diabetes patients treated with insulin glargine or detemir were switched from their basal insulin to insulin degludec. The primary end-points were the changes in glycated hemoglobin (HbA1c) from baseline at 3, 6 and 12 months.

Comparison of the efficacy of sitagliptin and glimepiride dose-up in Japanese patients with type 2 diabetes poorly controlled by sitagliptin and glimepiride in combination.

Aims/introduction: The goal of the study was to examine the effects of sitagliptin dose-up or glimepiride dose-up in Japanese patients with type 2 diabetes who were controlled inadequately by sitagliptin and glimepiride in combination.

Materials And Methods: A multicenter, prospective, randomized, open-label study was carried out in 50 patients with type 2 diabetes treated with sitagliptin and low-dose glimepiride. The patients were randomly assigned to receive the addition of 50 mg/day sitagliptin or 0.

Efficacy and safety of sitagliptin as add-on therapy on glycemic control and blood glucose fluctuation in Japanese type 2 diabetes subjects ongoing with multiple daily insulin injections therapy.

To assess the efficacy and safety of adding sitagliptin, an oral dipeptidyl peptidase-4 inhibitor, in subjects with type 2 diabetes inadequately controlled with multiple daily insulin injections therapy (MDI). HbA1c, 1,5-anhydroglucitol (1,5-AG), body mass index (BMI), insulin doses, six-point self-measured plasma glucose (SMPG) profiles were assessed before, after 12 weeks, and after 24 weeks of MDI with 50 mg/day of sitagliptin in 40 subjects with type 2 diabetes. Safety endpoints included hypoglycemia and any adverse events.

Ezetimibe improves glucose metabolism by ameliorating hepatic function in Japanese patients with type 2 diabetes.

Unlabelled: Aims/Introduction:  Several experimental studies have shown that ezetimibe improves steatosis and insulin resistance in the liver. This suggests that ezetimibe may improve glucose metabolism, as well as lipid metabolism, by inhibiting hepatic lipid accumulation. Therefore, we compared HbA1c levels after 3 months ezetimibe treatment with baseline levels in patients with type 2 diabetes and examined the factors associated with reductions in HbA1c following ezetimibe administration.

A case of ectopic adrenocorticotropic hormone-producing pancreatic neuroendocrine tumor with multiple liver metastases.

Ectopic adrenocorticotropic hormone (ACTH) production by the pancreatic neuroendocrine tumor (p-NET) is relatively rare, and patients with this tumor show poor prognosis. In this study, we present the case of a 64-year-old woman who presented with ectopic ACTH syndrome due to p-NET with multiple liver metastases. Computed tomography revealed that she had multiple masses in the liver and a solid mass in the head of the pancreas.

Development of a highly responsive needle-type glucose sensor using polyimide for a wearable artificial endocrine pancreas.

To produce a long-life, stable, miniature glucose sensor for a wearable artificial endocrine pancreas (WAEP), we developed a novel microneedle-type glucose sensor using polyimide, designated the PI sensor (outer diameter, 0.3 mm; length, 16 mm), and investigated its characteristics in vitro and in vivo. In the in vitro study, we tested the sensor in 0.

Comparison between closed-loop portal and peripheral venous insulin delivery systems for an artificial endocrine pancreas.

To establish the ideal insulin delivery route for an artificial endocrine pancreas, we examined the effectiveness of closed-loop portal insulin delivery. We investigated the effects of the route of insulin delivery on net hepatic glucose balance (NHGB) in dogs under pancreatic clamp conditions with somatostatin plus basal glucagon and insulin infusions. A constant rate of suprabasal insulin was infused via the portal vein or a peripheral vein, and glucose was infused into the portal vein for 180 min.

Strict glycemic control in diabetic dogs with closed-loop intraperitoneal insulin infusion algorithm designed for an artificial endocrine pancreas.

The ultimate goal of the development of an artificial endocrine pancreas is to achieve long-term strict glycemic regulation. To establish the physiological insulin delivery route of the artificial endocrine pancreas, intraperitoneal insulin infusion may be important. For this purpose, we tried to develop a closed-loop intraperitoneal insulin infusion algorithm by analyzing the pharmacokinetics of intraperitoneal regular insulin absorption using a mathematical model.
