The insufficient activity of insulin and the hyperactivity of glucagon are responsible for glucose intolerance in patients with type 2 diabetes. Whereas sodium-glucose cotransporter-2 (SGLT2) inhibitors improve blood glucose levels in patients with type 2 diabetes, their effects on the secretion profiles of glucagon and incretins remain unclear. Therefore, to investigate the effects of the SGLT2 inhibitor luseogliflozin on metabolic and endocrine profiles, 19 outpatients with type 2 diabetes were administered luseogliflozin for 12 weeks. It is of note that all subjects were treated only with diet and exercise therapy, and we were able to investigate the effects of luseogliflozin separately from the effects of other antidiabetic agents. Body weight, body fat mass, fat-free mass, and muscle mass were significantly reduced after 12 weeks of luseogliflozin administration. Glycosylated hemoglobin significantly decreased from the baseline of 8.2% ± 0.8% to 7.3% ± 0.7% (p < 0.0001). The meal tolerance test demonstrated that luseogliflozin significantly recovered glucose tolerance, accompanied by improved insulin resistance and β-cell function, whereas glucagon secretion was unaffected. Furthermore, GLP-1 secretion was significantly increased after luseogliflozin administration. Thus, luseogliflozin improved metabolic and endocrine profiles accompanied by increased GLP-1 secretion in type 2 diabetic patients without any antidiabetic medication, but did not affect glucagon secretion.

Diabetes mellitus complicated with insulin antibodies is rare in clinical practice but usually difficult to control. A high amount of insulin antibodies, especially with low affinity and high binding capacity, leads to unstable glycemic control characterized by hyperglycemia unresponsive to large volume of insulin and unanticipated hypoglycemia. There are several treatment options, such as changing insulin preparation, immunosupression with glucocorticoids, and plasmapheresis, most of which are of limited efficacy. Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a novel class of drug which decrease renal glucose reabsorption and lowers plasma glucose level independent of insulin action. We report here a case with diabetes complicated with insulin antibodies who was effectively controlled by an SGLT2 inhibitor. A 47-year-old man with type 2 diabetes treated with insulin had very poor glycemic control characterized by postprandial hyperglycemia unresponsive to insulin therapy and repetitive hypoglycemia due to insulin antibodies. Treatment with ipragliflozin, an SGLT2 inhibitor, improved HbA1c from 8.4% to 6.0% and glycated albumin from 29.4% to 17.9%. Continuous glucose monitoring revealed improvement of glycemic profile (average glucose level from 212 mg/dL to 99 mg/dL and glycemic standard deviation from 92 mg/dL to 14 mg/dL) with disappearance of hypoglycemic events. This treatment further ameliorated the characteristics of insulin antibodies and resulted in reduced insulin requirement. SGLT2 inhibitors may offer an effective treatment option for managing the poor glycemic control in diabetes complicated with insulin antibodies.
