トクシマケン ノ アタラシイ トウニョウビョウ イリョウ レンケイ オ メザス ココロミ

The annual incidence of diabetes-related death in Tokushima Prefecture has kept the highest in Japan since１９９２, except２００７. Such high incidence of death in diabetic patients might be related to renal failure and myocardial infarction. Therefore, we should make more effort to prevent diabetic micro-and macro-angiopathy. Since the number of diabetologist was not enough to cover Tokushima Prefecture, most of diabetic patients were treated by family doctors. It is, therefore, important to create a bidirectional network for diabetes care between family doctors and diabetologists. We just have been established a novel medical network for diabetic patients, so called“Tokushima Medical Net”, in which family doctors and diabetologists easily communicate medical records in each other using by the cloud computing system. We believe that expansion of this network over Tokushima Prefecture could contribute to improve disease management and decrease advanced complications in diabetic patients

Clinical impact of sarcopenia and dynapenia on diabetes

Sarcopenia as a progressive and generalized skeletal muscle disorder that is associated with an increased likelihood of adverse outcomes, including falls, fractures, physical disability, and mortality. On the other hand, an age-related decline in muscle strength prior to the reduction of muscle mass, is proposed to be "dynapenia". Sarcopenia and dynapenia has recently been recognized as a diabetic complications in type 2 diabetes. We firstly indicated that sarcopenia was frequently observed in 16.6% of patients with type 1 diabetes aged even over 40 years. Additionally, we recently reported that the prevalence rate of dynapenia was higher than sarcopenia in patients with type 2 diabetes. Chronic hyperglycemia also accelerates accumulation of advanced glycation end products (AGEs), which causes diabetic vascular complications through oxidative stress and chronic inflammation. We also demonstrated that skin autofluorescence (AF) as a marker of AGEs, was the independent determinant for skeletal muscle mass and strength in patients with type 2 diabetes and muscle strength in type 1 diabetes. Therefore, the early diagnosis of muscle weakness is essential for patients with diabetes and sustained good glycemic control with exercise and dietary intervention might be beneficial to prevent the progression of muscle weakness in these patients

A Review of Insulin-Dosing Formulas for Continuous Subcutaneous Insulin Infusion (CSII) for Adults with Type 1 Diabetes

Dosing guidelines for patients with type 1 diabetes using continuous subcutaneous insulin infusion (CSII), which are historically based on clinical experience and retrospective studies of patients consuming an American diet, recommend that basal insulin should represent approximately 50 % of the total daily dose (TDD). Recent prospective studies in the USA and Japan conclude that the more appropriate proportion is closer to 30–40 % of TDD. In addition, currently used formulas for calculating the carbohydrate-to-insulin ratio (CIR) and correction factor (CF) may lead to underdosing of bolus insulin by as much as 12.8–50 % for a hypothetical patient. The discrepancies between traditional formulas and data from newer studies can be accounted for by the more rigorous design of the newer studies (e.g., prospective design, controlled diets, meal omission, and frequent glucose monitoring). International differences in diet composition may also be important to consider when developing dosing recommendations for CSII

Role of Reactive Oxygen Species in the Progression of Type 2 Diabetes and Atherosclerosis

Type 2 diabetes is the most prevalent and serious metabolic disease all over the world, and its hallmarks are pancreatic β-cell dysfunction and insulin resistance. Under diabetic conditions, chronic hyperglycemia and subsequent augmentation of reactive oxygen species (ROS) deteriorate β-cell function and increase insulin resistance which leads to the aggravation of type 2 diabetes. In addition, chronic hyperglycemia and ROS are also involved in the development of atherosclerosis which is often observed under diabetic conditions. Taken together, it is likely that ROS play an important role in the development of type 2 diabetes and atherosclerosis

Use of iGlarLixi for Management of Type 2 Diabetes in Japanese Clinical Practice : SPARTA Japan, a Retrospective Observational Study

Introduction: Many individuals with type 2 diabetes (T2D) experience suboptimal glycemic control. Treatment intensification options include fixed-ratio combination products containing a basal insulin and a glucagon-like peptide-1 receptor agonist, such as iGlarLixi (insulin glargine 100 U/mL and lixisenatide). This study aimed to provide real-world evidence of the effect of iGlarLixi in Japanese clinical practice. Methods: SPARTA Japan was a non-comparative, observational study conducted at 27 institutions in Japan. Anonymized individual-level data from adults with T2D receiving iGlarLixi in routine clinical practice were retrospectively collected. The primary study objective was to assess the impact of iGlarLixi on the change in glycated hemoglobin (HbA1c) at 6 months’ post-treatment initiation, with preplanned subanalyses to determine the influence of baseline characteristics. Secondary and exploratory endpoints included assessment of the proportion of individuals achieving HbA1c targets, change in body weight, and incidence and severity of hypoglycemia and gastrointestinal events. Results: The full analysis set included 432 individuals, with data available at 6 months for 426. Of the 432 individuals, the mean (SD) age at baseline was 61.6 (12.8) years and the majority had a T2D duration of ≥ 10 years [mean (SD) 13.3 (10.4) years]. At 6 months, HbA1c had significantly decreased versus baseline ( –0.85%; P < 0.0001), with a greater decrease in those aged < 65 years, with a shorter duration of T2D and higher baseline HbA1c. A significant increase in the proportion of participants achieving age-specific HbA1c versus baseline was observed. Mean body weight decreased by 0.5 kg (P = 0.0034 versus baseline). There were few hypoglycemia and gastrointestinal events (in individuals with HbA1c data); no severe hypoglycemic events were reported. Conclusions: The results of this real-world study indicate that iGlarLixi may improve glycemic control without serious adverse events in Japanese individuals with T2D who have suboptimal glycemic control on current treatment regimens and switch to iGlarLixi

Nasal glucagon as a viable alternative for treating insulin‐induced hypoglycaemia in Japanese patients with type 1 or type 2 diabetes : A phase 3 randomized crossover study

Aim: To compare nasal glucagon (NG) with intramuscular glucagon (IMG) for the treatment of insulin‐induced hypoglycaemia in Japanese patients with type 1 (T1DM) or type 2 diabetes mellitus (T2DM). Materials and methods: This phase 3, randomized, open‐label, two‐treatment, two‐period crossover non‐inferiority study enrolled Japanese adults with T1DM or T2DM on insulin therapy, with glycated haemoglobin levels ≤86 mmol/mol (≤10%). After ≥8 hours of fasting, hypoglycaemia was induced with human regular insulin (intravenous infusion). Patients received NG 3 mg or IMG 1 mg approximately 5 minutes after insulin termination. The primary endpoint was the proportion of patients achieving treatment success [plasma glucose (PG) increase to ≥3.9 mmol/L (≥70 mg/dL) or ≥1.1 mmol/L (≥20 mg/dL) increase from the PG nadir within 30 minutes of receiving glucagon]. Non‐inferiority was declared if the upper limit of the two‐sided 95% confidence interval (CI) of the mean difference in the percentage of patients achieving treatment success (IMG minus NG) was <10%. Results: Seventy‐five patients with T1DM (n = 34) or T2DM (n = 41) were enrolled; 72 patients (50 men, 22 women) received ≥1 study drug dose (T1DM, n = 33; T2DM, n = 39). Sixty‐eight patients completed the study and were evaluable. All NG‐ and IMG‐treated patients achieved treatment success (treatment arm difference: 0%; upper limit of two‐sided 95% CI 1.47%); NG met prespecified conditions defining non‐inferiority versus IMG. Glucagon was rapidly absorbed after both nasal and intramuscular administration; PG profiles were similar between administration routes during the first 60 minutes post dose. Study drug‐related treatment‐emergent adverse events affecting >2 patients were rhinalgia, increased blood pressure, nausea, ear pain and vomiting in the NG group, and nausea and vomiting in the IMG group. Conclusion: Nasal glucagon was non‐inferior to IMG for successful treatment of insulin‐induced hypoglycaemia in Japanese patients with T1DM/T2DM, supporting use of NG as a rescue treatment for severe hypoglycaemia

Use of iGlarLixi for the Management of Type 2 Diabetes in Japanese Clinical Practice : Prior Treatment Subgroup Analysis of the SPARTA Japan Study

Introduction: iGlarLixi, a fixed-ratio combination of insulin glargine 100 U/mL and the glucagon-like peptide 1 receptor agonist (GLP-1 RA) lixisenatide, is one option for treatment intensification in individuals with type 2 diabetes (T2D) who are unable to achieve targeted glycaemic control with their current glucose-lowering agent. Real-world data on the impact of prior treatment on the effectiveness and safety of iGlarLixi may be useful to guide individualised treatment decisions. Methods: This analysis of the 6-month, retrospective, observational SPARTA Japan study compared glycated haemoglobin (HbA1c), body weight and safety for pre-specified subgroups defined by prior treatment: post oral antidiabetic agent (OAD), GLP-1 RA, basal insulin (BI) + OADs (BOT), GLP-1 RA + BI or multiple daily injections (MDI). The post BOT and MDI subgroups were further divided on the basis of prior dipeptidyl peptidase 4 inhibitor (DPP-4i) use, and the post MDI group was divided on the basis of whether participants continued bolus insulin. Results: Of the 432 participants in the full analysis set (FAS), 337 were included in this subgroup analysis. Across subgroups, mean baseline HbA1c ranged from 8.49% to 9.18%. iGlarLixi significantly (p < 0.05) reduced mean HbA1c from baseline in all but the post GLP-1 RA + BI group. At 6 months, these significant reductions ranged from 0.47% to 1.27%. Prior DPP-4i exposure had no impact on the HbA1c-lowering effect of iGlarLixi. Mean body weight decreased significantly in the FAS (0.5 kg) and the post BOT (1.2 kg) and MDI (1.5 and 1.9 kg) subgroups but increased in the post GLP-1 RA subgroup (1.3 kg). iGlarLixi treatment was generally well tolerated, with very few participants discontinuing because of hypoglycaemia or gastrointestinal events. Conclusion: In participants with suboptimal glycaemic control on various regimens, 6 months of iGlarLixi treatment improved HbA1c in all but one prior treatment subgroup (GLP-1 RA + BI), and was generally well tolerated

Risk of hypoglycemia in Japanese people with type 2 diabetes mellitus who initiated or switched to insulin glargine 300 U/mL : A subgroup analysis of 12-month post-marketing surveillance study (X-STAR study)

Aims: This study investigated the hypoglycemia risk in people with type 2 diabetes (T2D) who initiated or switched to insulin glargine 300 U/mL (Gla-300) by stratifying them by age and renal function. Methods: We examined data from 4621 people with T2D (1227 insulin-naïve and 3394 insulin-experienced) of the X-STAR study, a prospective, observational, 12-month study conducted from December 2015 to August 2018 in Japan. Participants were stratified by age (<65, 65 to <75, and ≥75 years) and estimated glomerular filtration rate (eGFR) (≥90, 60 to <90, 30 to <60, and <30 mL/min/1.73 m2). Hypoglycemia was defined according to the Ministry of Health, Labour and Welfare manual of Japan. Results: No apparent increase in the proportion of people who experienced hypoglycemia was found in all subgroups. The proportions were 2.9–3.5% and 2.7–5.2% of insulin-naïve and insulin-experienced people, respectively, for age subgroups, and 2.4–4.7% and 4.6–4.8%, respectively, for eGFR subgroups. The result was similar for HbA1c levels below and at or above 7.0% in all age subgroups. Conclusions: Our study found no apparent increase in the hypoglycemia risk in people with older age and renal impairment who were administered Gla-300. These results would provide reassuring information on Gla-300 use
