Aims/Introduction: Six kinds of oral antidiabetic drugs (OADs), including the new dipeptidyl peptidase 4 (DPP-4) inhibitors, are available. The present study aimed to define trends within the prescribing patterns of OADs, as well as changes in glycemic control in Japan over a 10-year period from 2002 to 2011. Materials and Methods: We carried out a cross-sectional study using data of type 2 diabetes mellitus patients from 24 clinics for 2002, 2005, 2008 and 2011. OAD use was analyzed combined with clinical data. Results: Sulfonylureas (SUs) were the most commonly used OAD, but their use for monotherapy markedly decreased over the study period. Biguanides (BGs) were the second most commonly used OAD, and their prescribing rate increased both for mono- and combination therapy. DPP-4 inhibitors (DPP-4I), released in 2009, were the third most commonly prescribed OAD in 2011 both for mono- and combination therapy. Among combination therapies, two OADs were mostly prescribed, but the use of three OADs and four OADs in 2011 was two- and 14.8-fold those in 2002. These trends were accompanied by an improvement in average glycated hemoglobin from 7.5 ± 1.2% in 2002 to 7.1 ± 0.9% in 2011. Conclusions: The OAD prescribing trend has moved away from monotherapy with SUs and toward combination therapies to achieve better glycemic control. Increased use of BGs and DPP-4I was predominant in 2011. These trends were accompanied by an improvement of the glycated hemoglobin level. © 2013 The Authors. Source

OBJECTIVE: Glycaemic control is critical to prevent diabetic complications and mortality. This 6-month, open-label, observational study assessed the efficacy and safety of switching Japanese patients with type 2 diabetes from neutral protamine Hagedorn (NPH) insulin to insulin detemir. METHODS: Patients with type 2 diabetes (n = 126) receiving basal-bolus insulin therapy with NPH insulin plus rapid-acting insulin analogues were recruited. NPH insulin was replaced with insulin detemir for 6 months. Glycosylated haemoglobin (HbA1c), fasting plasma glucose (FPG), daily glucose levels and hypoglycaemia were monitored. Nocturnal quality of life was assessed by insulin therapy related quality of life at night questionnaire. RESULTS: HbA1c, FPG and body weight were all significantly reduced after treatment with insulin detemir for 6 months, without increasing severe hypoglycaemia. Insulin dose increased significantly over the same time. There were significant improvements in overall nocturnal quality of life, as well as well-being. CONCLUSIONS: Treatment with insulin detemir for 6 months resulted in substantial benefits, including reduced HbA1c, FPG and body weight, and improvements in nocturnal quality of life, without increasing hypoglycaemia. © 2012 Field House Publishing LLP.

Aims To investigate whether a reduced incidence of cardiovascular disease in Type2 diabetes can be achieved in a newly recruited cohort following the recently advanced concept of multifactorial treatment and followed in primary care settings as compared with earlier cohorts. Methods A prospective study was performed in primary care settings at multiple clinics nationwide in the Japan Diabetes Clinical Data Management (JDDM) study group. Subjects were 2984 patients with Type2 diabetes without prevalent cardiovascular disease. The main outcome measure was the first event of non-fatal or fatal coronary heart disease, ischaemic stroke or peripheral artery disease, and the incidence was compared with other representative cohorts. Results There were 90 cardiovascular events over 10827 person-years of follow-up with a dropout rate of 6%. The incidences (per 1000 person-years, 95% confidence interval) of composite, coronary heart disease, ischaemic stroke and peripheral artery disease in the JDDM study were 8.3 (6.6-10.0), 4.4 (3.2-5.6), 3.1 (2.1-4.2), and 0.7 (0.2-1.2), respectively. Each incidence was lowest in the JDDM study compared with other cohorts (P<0.01 vs. each cohort). In the JDDM study, significant variables predictive of the occurrence of a cardiovascular event were age, duration of diabetes, HbA 1c, HDL cholesterol and urinary albumin. Conclusion The novel finding of low cardiovascular disease occurrence in this study may be conferred by the feasibility at primary care settings for providing patients with Type2 diabetes with favourable control of blood glucose, blood pressure and lipids, coupled with unique ethnicity/country factors. © 2011 The Authors.

Aim: Glucagon is recommended to treat severe hypoglycemia in nonhospital environments, when a patient with type 1 diabetes mellitus (T1DM) is unconscious and unable to eat or drink. However, the actual possession rate of glucagon in Japan has not been investigated. Subjects and Methods: We recruited 208 T1DM patients older than 15 years of age. The patients were treated at 16 hospitals and clinics in different regions of Japan. Answers were obtained using a self-Administered questionnaire about the possession, the experience of usage, and the preference to possess glucagon after reading what is glucagon and when it is used. A stepwise logistic regression analysis was performed to assess the influence of various factors on the possession of glucagon. Results: The possession rate of glucagon was 15.9%, and the rate of those who had experience of using glucagon to treat severe hypoglycemia was 6.0%. The rate of preference to possess glucagon at home after reading the description of glucagon was 39.0%. The possession of glucagon was significantly associated with results of the Glucagon Knowledge Test (odds ratio=24.1; 95% confidence interval, 3.2-183.3; P=0.002) and the history of severe hypoglycemia within 1 year (odds ratio=4.8; 95% confidence interval, 2.0-12.0; P=0.001). Conclusions: Glucagon as a measure to treat severe hypoglycemia was underutilized among T1DM patients in Japan. © Copyright 2013, Mary Ann Liebert, Inc. 2013. Source

Background: Although the circulating levels of remnant-like particle cholesterol (RLP-C) or serum amyloid A-low-density lipoprotein (SAA-LDL) can individually be increased in subjects with metabolic syndrome (MetS), the correlation between the two markers has not yet been previously studied. In the present study, we aimed to investigate the correlation between RLP-C and SAA-LDL in obese subjects with MetS in comparison to those without MetS. Methods: A total of 436 obese subjects were divided into groups with MetS and without MetS (male/female 75/143, mean age 49 years, current smokers 16% in both groups) by applying the age-, gender-, and smoking habit-matching method based on the database in the multicenter Japan Obesity and Metabolic Syndrome Study (JOMS). The data, including RLP-C and SAA-LDL, were compared in each group. Results: Significantly greater levels of RLP-C or SAA-LDL were observed in subjects with MetS in comparison with those without MetS. There was a significantly positive correlation between RLP-C and SAA-LDL, with a relatively greater correlation in subjects with MetS (coefficient = 0.290, P < .01) in comparison with those without MetS (coefficient = 0.181, P <.01). Multivariate-adjusted correlation analyses showed a greater correlation between RLP-C and SAA-LDL in subjects with MetS, relative to those without MetS, although the significant correlation decreased in both groups when the hypertriglyceridemic states were taken into account. Conclusions: A relatively greater and positive correlation between greater levels of RLP-C and SAA-LDL in obese subjects with MetS, in comparison with those without MetS, may be linked to the development of MetS-related cardiovascular disease. © Georg Thieme Verlag KG Stuttgart · New York.
