Dipeptidyl peptidase-4 inhibitors (DPP-4Is) are one of the most frequently prescribed anti-diabetic agents in Japan, and they are often used in combination with insulin secretagogues, such as sulfonylureas and glinides. Crenolanib PDGFR inhibitor In the present study, we determined the efficacy and safety of the use of repaglinide or glimepiride, a sulfonylurea, in combination with a DPP-4I, in Japanese patients with type 2 diabetes mellitus (T2DM). This study was an investigator-initiated, open-label, randomized, multi-center prospective study. Patients with T2DM, which was inadequately controlled using a DPP-4I, were randomized to a repaglinide group or a glimepiride group and treated for 48weeks. The primary outcomes were the reductions in glycated hemoglobin (HbA1c) and glucose oscillation, identified using continuous glucose monitoring, after 12weeks. The secondary outcome was the change in carotid intima-media thickness (IMT), measured by ultrasonography, after 48weeks. A total of 61 patients were recruited and analyzed in the study. Twelve weeks of treatment with 1.5mg repaglinide or 1mg glimepiride significantly reduced HbA1c, and a larger reduction in HbA1c occurred in the repaglinide group than the glimepiride group. Mean subcutaneous glucose concentration was significantly reduced in both groups, but the glucose oscillation did not decrease. Interestingly, the mean left IMT significantly increased in the glimepiride group, but not in the repaglinide group. More hypoglycemic events were observed in the glimepiride group. These data suggest that repaglinide reduces HbA1c more effectively than glimepiride when used in combination with a DPP-4I, and causes fewer hypoglycemic events.

The 75-g oral glucose tolerance test (OGTT) was performed in case of positive results of universal screening of a 50-g glucose challenge test at 24-28 weeks' gestation in Japanese pregnant women. These women were treated in our hospital between 2012 and 2016. Among these women, 30 with a body mass index of less then 18.5 kg/m2 were selected as lean subjects. Nine women were diagnosed with GDM (GDM group) and the remaining 21 had normal glucose tolerance (control group). For evaluating insulin secretion or resistance, the following parameters were compared between the two groups together with a family history of diabetes mellitus (DM) among first-degree relatives (1) plasma glucose and immnunoreactive insulin (IRI) levels after glucose loading, (2) insulinogenic index (I.I), (3) homeostasis model assessment of β-cell function (HOMA-β), (4) homeostasis model assessment of insulin resistance (HOMA-IR), and (5) insulin sensitivity index (ISI) composite. The percentage of having a family history of DM was significantly higher in the GDM group (3/9, 33.3%) than in the control group (0/21, 0.0%, P less then 0.001). Serum glucose levels at 30, 60, and 120 min after glucose loading were significantly higher in the GDM group than in the control group (all P less then 0.05). IRI levels at 60 and 120 min were significantly higher in the GDM group than in the control group (both P less then 0.05), and they showed persistent insulin secretion patterns. Values of the I.I. and ISI composite were significantly lower in the GDM group than in the control group (both P less then 0.05), with no differences in HOMA-β, HOMA-IR and HbA1c levels between the groups. Lean Japanese pregnant women with GDM have impaired β-cell function, which is in part associated with hereditary traits. In recent years, support for coexisting diabetes treatment and work ( ) has become increasingly important for employees with diabetes. It is important to identify factors associated with
