PurposeThe factors associated with the renal prognosis over six months after the initiation of empagliflozin were compared between the non-elderly and elderly Japanese patients with type 2 diabetes.Patients and methodsIn total, 132 patients treated with empagliflozin (10 mg, once daily) were studied as the safety analysis set. One hundred ten subjects whose medications were not changed during the observation period were investigated as the full analysis set to assess the effectiveness. The subjects were divided into two groups: non-elderly subjects (n=72) of<65 years of age and elderly subjects (n=38) of≥65 years of age.ResultsAlthough the body weight and HbA1c, AST, ALT and γ-GTP levels were significantly reduced in both the non-elderly and elderly subjects, blood pressure, eGFR and urinary protein excretion were only significantly decreased in the non-elderly subjects. The hemoglobin, hematocrit and serum HDL-cholesterol levels were significantly elevated in both groups. The change in eGFR showed a significant positive association with the change in blood pressure. The change in urinary protein excretion tended to be correlated with the change in blood pressure.ConclusionAlthough renoprotective effects might be limited, empagliflozin can safely and effectively improve metabolic parameters, even in elderly subjects.

BackgroundWe investigated 1) the frequency of hypertension in patients with type 2 diabetes graded by the new classification of chronic kidney disease (CKD) reported by the Kidney Disease: Improving Global Outcomes (KDIGO) and 2) the number of antihypertensive agents needed to achieve treatment goals using a prospective observational study.MethodsA population of 2018 patients with type 2 diabetes mellitus was recruited for the study. The CKD stage was classified according to the eGFR and the urinary albumin excretion levels.ResultsHypertension was found in 1420 (70%) of the patients, and the proportion of subjects showing a blood pressure < 130/80 mmHg was 31% at the baseline. Although the mean blood pressure was approximately 130/75 mmHg, the rate of patients with a blood pressure of < 130/80 mmHg became limited to 41-50% during the observation period. The number of antihypertensive agents required for treatment was significantly higher at the endpoint (2.0 ± 1.3) than at the baseline (1.6 ± 1.2). Furthermore, it increased with the progression of the CKD stage at both the baseline and the endpoint of the observation. However, the frequency of subjects who did not achieve the blood pressure target was found to increase in the group demonstrating the later stage of CKD.ConclusionsHypertension resistant to antihypertensive agents was common in the patients with type 2 diabetes mellitus and increased with the progression of CKD. Although powerful combination therapy using antihypertensive agents is considered necessary for the strict control of blood pressure, this became difficult in individuals who were in advanced stages as graded based on the eGFR and the urinary albumin excretion levels.

BackgroundWe investigated the trends in the clinical characteristics and prescriptions of type 2 diabetic patients with severe hypoglycemia because the prescription rate of antidiabetic agents has significantly changed recently.MethodsA total of 193 patients with type 2 diabetes with severe hypoglycemia induced by antidiabetic agents between 2008 and 2013 were divided into three groups based on the period of visit: 2008 - 2009, 2010 - 2011 and 2012 - 2013.ResultsWhile the proportion of patients with severe hypoglycemia using insulin (from 55% to 74%), biguanides (from 6% to 20%), glinides, and dipeptidyl peptidase-4 inhibitors significantly increased, those using sulfonylureas (from 45% to 20%) significantly decreased. Errors of drug use significantly increased as a trigger of hypoglycemia in recent years. The number of antidiabetic agents (from 1.9 ± 0.6 to 2.3 ± 0.7), non-diabetic agents (from 2.3 ± 2.4 to 4.3 ± 3.3), and total drugs prescribed were significantly higher in recent years among patients receiving insulin therapy.ConclusionsPolypharmacy especially in patients receiving insulin therapy and errors of drug use have increased in type 2 diabetic patients with severe hypoglycemia in recent years. Intensive education in the usage rule of drugs is considered to be important in order to prevent severe hypoglycemia.

Objective: We compared the clinical course of type 2 diabetic patients whose basal insulin preparations were replaced from insulin glargine (IGlar) 100 units/mL (U100) to IGlar biosimilar or IGlar 300 units/mL (U300).Methods: After propensity score matching, 34 patients whose basal insulin preparation was switched from IGlar U100 to IGlar biosimilar and 102 switched to IGlar U300 were observed for 6 months.Results: The HbA1c level and body weight did not change significantly after the replacement in the IGlar biosimilar or IGlar U300 groups. In the IGlar biosimilar group, the frequency of subjects who experienced hypoglycemia after the replacement (12%) was not different from before (12%). However, the frequency was significantly lower after the replacement (2%) than before (13%) in the IGlar U300 group. The change in the HbA1c level after the replacement showed a significant association with the HbA1c level at the baseline but not with the kind of IGlar. Hypoglycemia was frequently observed in subjects who had experienced hypoglycemia before the replacement.Conclusions: IGlar biosimilar and IGlar U300 induced similar HbA1c and body weight changes among type 2 diabetic patients. IGlar biosimilar is a suitable option for patients with a low risk for hypoglycemia.
