BACKGROUND We recently reported that short-term treatment with liraglutide (20.0 ± 6.4 days) reduced body weight and improved some scales of eating behavior in Japanese type 2 diabetes inpatients. However, it remained uncertain whether such liraglutide-induced improvement is maintained after discharge from the hospital. The aim of the present study was to(More)
Insulin-dependent diabetes mellitus (IDDM) is assumed to be a T cell-mediated autoimmune disease. To investigate the role of Fas-mediated cytotoxicity in pancreatic beta cell destruction, we established nonobese diabetic (NOD)-lymphoproliferation (lpr)/lpr mice lacking Fas. Out of three genotypes, female NOD-+/+ and NOD-+/lpr developed spontaneous diabetes(More)

BACKGROUND To examine the effects of liraglutide, a glucagon-like peptide-1 (GLP-1) analogue, on visceral fat adiposity, appetite, food preference, and biomarkers of cardiovascular system in Japanese patients with type 2 diabetes. METHODS The study subjects were 20 inpatients with type 2 diabetes treated with liraglutide [age; 61.2 ± 14.0 years, duration(More)
UNLABELLED Aims/Introduction:  Recently, glucagon-like peptide-1 (GLP-1) receptor agonists of liraglutide have become available in Japan. It has not yet been clarified what clinical parameters could discriminate liraglutide-effective patients from liraglutide-ineffective patients. MATERIALS AND METHODS   We reviewed 23 consecutive patients with type 2(More)

Evidence suggests that visceral fat accumulation plays a central role in the development of metabolic syndrome. Excess visceral fat causes local chronic low-grade inflammation and dysregulation of adipocytokines, which contribute in the pathogenesis of the metabolic syndrome. These changes may affect the gene expression in peripheral blood cells. This study(More)
We have revised a part of the diagnostic criteria for fulminant type 1 diabetes. The new criteria were set both to express the essence of this disease of rapid increase of patients' blood glucose and to be highly sensitive to reduce the misdiagnosis. After analyzing the data of 382 patients with newly-diagnosed fulminant type 1 diabetes, we adopted the(More)
OBJECTIVE To examine the contribution of the CTLA4 gene in the susceptibility to fulminant type 1 diabetes and compare it with classic type 1A diabetes. RESEARCH DESIGN AND METHODS We genotyped the +49G>A and CT60G>A variants of the CTLA4 gene in fulminant type 1 diabetic patients (n = 55), classic type 1A diabetic patients (n = 91), and healthy control(More)
Type 1 diabetes is a disease characterized by destruction of pancreatic β-cells, which leads to absolute deficiency of insulin secretion. Depending on the manner of onset and progression, it is classified as fulminant, acute-onset or slowly progressive type 1 diabetes. Here, we propose the diagnostic criteria for acute-onset type 1 diabetes mellitus. Among(More)
AIMS/INTRODUCTION Recently, dipeptidyl peptidase-4 (DPP-4) inhibitors have become available in Japan. It has not yet been clarified what clinical parameters could discriminate DPP-4 inhibitor-effective patients from DPP-4 inhibitor-ineffective patients. MATERIALS AND METHODS We reviewed 33 consecutive patients with type 2 diabetes admitted to Osaka(More)
BACKGROUND Although many Asian type 2 diabetic patients have been considered to be not obese and have low capacity of insulin secretion, the proportion of obese patients with visceral fat accumulation has increased in recent years. We found previously considerable number of Japanese non-obese subjects (body mass index (BMI) < 25 kg/m²) with visceral fat(More)
