Trends in glycemic control in patients with insulin therapy compared with non-insulin or no drugs in type 2 diabetes in Japan: a long-term view of real-world treatment between 2002 and 2018 (JDDM 66).

Introduction: We investigated trends in the proportion of diabetes treatment and glycemic control, which may be altered by recent advances in insulin and non-insulin drugs, in Japanese patients with type 2 diabetes.

Research Design And Methods: A serial cross-sectional study was performed using a multicenter large-population database from the Japan Diabetes Clinical Data Management study group. Patients with type 2 diabetes who attended clinics belonging to the study group between 2002 and 2018 were included to examine trends in glycated hemoglobin A1c (HbA1c) by treatment group using multivariable non-linear regression model.

Cross sectional study on proportion of sulfonylureas among various oral antidiabetic drugs using for Japanese patients with type 2 diabetes, analyzed from NSAID Study-2.

Aim: We aimed to investigate the certainty of using sulfonylureas in Japanese patients with type 2 diabetes mellitus (T2DM) by analyzing data from the 2018 Nationwide Survey on Actual Intervention for T2DM by Japanese Practitioners (NSAID Study).

Methods: Of the 6525 and 1545 participants in the NSAID Study under the care of general practitioners (GP) and diabetes specialists (SP), respectively, we included 5423 (83.1%) and 1058 (68.

Differences in Dental Care Referral for Diabetic Patients Between General Practitioners and Diabetes Specialists in Japan, Analyzed from NSAID-Study 3.

Introduction: Periodontal disease is a common inflammation worldwide and is not only the foremost cause of tooth loss but also a cause of deterioration of glycemic control in patients with diabetes mellitus. In addition, effective glycemic management improves the control of periodontitis infection. The aim of this study was to clarify whether awareness of the need to refer their patients with diabetes to dentists differs between general practitioners and diabetes specialists.

Nationwide Survey on Actual Interventions for Type 2 Diabetes by Japanese Practitioners (NSAID Study-1): Glycemic, Weight, and Blood Pressure Management.

Introduction: Considering the increase in the number of patients with diabetes, the quality of diabetes care provided by general practitioners (GP) is critical for preventing complications. We performed a nationwide survey to determine whether the diabetic management provided to patients with type 2 diabetes mellitus (T2DM) by Japanese practitioners is appropriate.

Methods: We randomly selected 463 clinics throughout Japan; 8070 patients with T2DM (6525 and 1545 under the care of GP and specialists [SP], respectively) were enrolled.

The Prognosis of Patients With Type 2 Diabetes and Nonalbuminuric Diabetic Kidney Disease Is Not Always Poor: Implication of the Effects of Coexisting Macrovascular Complications (JDDM 54).

Objective: Nonalbuminuric diabetic kidney disease (DKD) has become the prevailing phenotype in patients with type 2 diabetes. However, it remains unclear whether its prognosis is poorer than that of other DKD phenotypes.

Research Design And Methods: A total of 2,953 Japanese patients with type 2 diabetes and estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.

Effect of canagliflozin on the overall clinical state including insulin resistance in Japanese patients with type 2 diabetes mellitus.

Aims: Information on the clinical efficacy of SGLT2 inhibitors in the Japanese population is limited. The aim of this single-arm, single-center, open-label study was to confirm the body weight- and fat mass-lowering effects of canagliflozin (CANA) and the accompanying improvement in insulin resistance in Japanese patients with Type 2 diabetes mellitus (T2DM).

Methods: Thirty-eight patients were enrolled and administered 100 mg CANA once daily for 24 weeks.

Declining trends of diabetic nephropathy, retinopathy and neuropathy with improving diabetes care indicators in Japanese patients with type 2 and type 1 diabetes (JDDM 46).

Objective: We examined changes in prevalence of diabetic microvascular/macrovascular complications and diabetes care indicators for adults in Japan with type 2 and type 1 diabetes over one decade.

Research Design And Methods: Two independent cohorts were recruited with the same inclusion criteria in 2004 (cohort 1: 3319 with type 2 and 286 with type 1 diabetes) and in 2014 (cohort 2: 3932 with type 2 and 308 with type 1 diabetes). Prevalence of complications and care indicators including achieving treatment targets for glycemia, blood pressure, lipid control, body mass index (BMI), and smoking were compared.

Large-scale survey of rates of achieving targets for blood glucose, blood pressure, and lipids and prevalence of complications in type 2 diabetes (JDDM 40).

Objective: The fact that population with type 2 diabetes mellitus and bodyweight of patients are increasing but diabetes care is improving makes it important to explore the up-to-date rates of achieving treatment targets and prevalence of complications. We investigated the prevalence of microvascular/macrovascular complications and rates of achieving treatment targets through a large-scale multicenter-based cohort.

Research Design And Methods: A cross-sectional nationwide survey was performed on 9956 subjects with type 2 diabetes mellitus who consecutively attended primary care clinics.

Both glimepiride and high-dose metformin are important for sustained glucose lowering in Japanese type 2 diabetes patients on glimepiride-sitagliptin-metformin therapy: subanalysis of a single-center, open-label, randomized study.

Background: In a previous single-center, open-label randomized 3-month study of triple oral antidiabetes drug (OAD) therapy, we investigated factors affecting the glycemic control afforded by sitagliptin, high-dose metformin, and low-dose glimepiride. Patients were prospectively assigned to either Group 1 (50% reduction in metformin) or Group 2 (discontinuation of glimepiride) and compared. The results showed that the glycated hemoglobin (HbA1c) levels of patients in Group 2 deteriorated more than those in Group 1, whereas HbA1c levels were maintained in some patients in both groups.

Combination Therapy with a Dipeptidyl Peptidase-4 Inhibitor, Sulfonylurea, and Metformin Markedly Improves HbA1c Levels in Japanese Patients with Type 2 Diabetes Mellitus.

Combination therapy with a dipeptidyl peptidase (DPP)-4 inhibitor and metformin or sulfonylurea results in substantial and additive glucose-lowering effects in patients with type 2 diabetes mellitus (T2DM). However, it is not known whether triple combination therapy with a DPP-4 inhibitor, metformin, and sulfonylurea has greater additive effects or synergic effects. In the present report, we investigated the effect of addition of sitagliptin, the first-in-class DPP-4 inhibitor, to ongoing metformin and sulfonylurea therapy in three female Japanese patients with T2DM who refused insulin therapy.
