UNLABELLED Aims/Introduction:  The effectiveness of incretin-based therapies in Asian type 2 diabetes requires investigation of the secretion and metabolism of glucose-dependent insulinotropic polypepide (GIP) and glucagon-like peptide 1 (GLP-1). Plasma extractions have been suggested to reduce variability in intact GLP-1 levels among individuals by(More)
Although glucose-dependent insulinotropic polypeptide (GIP) levels have been characterized previously, GLP-1 levels in Asians remain unclear. Here, we investigate total and intact levels of GLP-1, as well as GIP during oral glucose and meal tolerance tests (OGTT and MTT) in Japanese patients with or without type 2 diabetes (T2DM). Seventeen Japanese healthy(More)
OBJECTIVE We investigated the role of family support in glycemic control by nutritional self-care behavior of Japanese patients with type 2 diabetes. METHODS One hundred twelve Japanese out-patients with type 2 diabetes were recruited for the study at Kansai Electric Power Hospital. Interviews were conducted and HbA1c and triglyceride levels were(More)
We examined GLP-1 secretion from the pancreas of a patient with glucagonoma and pancreatic resection by measuring GLP-1 after meal ingestion or selective arterial calcium injection, and immunohistochemical analysis. Our findings support the notion that GLP-1 is secreted from pancreatic α cells in humans.
AIMS/INTRODUCTION The safety and efficacy of insulin-to-liraglutide switch in type 2 diabetes has not been studied adequately. Here, we retrospectively characterize clinical parameters that might predict insulin-to-liraglutide treatment switch without termination due to hyperglycemia, and examine the effects of switching the therapies on glycated hemoglobin(More)
A generalized skin eruption with strong itching was induced by sitagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, in a patient almost 6 months after initiation of the drug. Physical examination revealed a spread of skin rash from chest to back, and abdomen and thigh. Discontinuation of the drug eliminated the skin rash immediately. The emergence of(More)
This study was initiated to identify clinical and dietary parameters that predict efficacy of dipeptidyl peptidase-4 inhibitors. A total of 72 untreated Japanese patients with type 2 diabetes who received DPP-4 inhibitors (sitagliptin, alogliptin or vildagliptin) for 4 months were examined for changes of glycated hemoglobin (HbA1c) and body mass index(More)
'Incretin' hormones has lately attracted considerable attention as new strategy improving insulin secretion of type 2 diabetes mellitus. Spending many years for study of incretin hormones, GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1), we can use incretin mimetics as new drugs for type 2 diabetes clinically today in(More)
