Abstract

Abstract: Aims/Introduction: Sodium–glucose cotransporter 2 (SGLT‐2) inhibitors improve blood glucose control, as well as reducing bodyweight by promoting urinary glucose excretion. The weight loss is less than expected from urinary glucose loss, however, likely because of an increase in food intake. To investigate whether SGLT‐2 inhibitors might increase appetite by affecting related hormones, we examined the effects of the SGLT‐2 inhibitor, ipragliflozin, including those on appetite‐regulating hormones, in individuals with suboptimally controlled type 2 diabetes. Materials and Methods: The present prospective, multicenter, open‐label study was carried out with 96 patients with a body mass index of ≥22 kg/m 2 who were treated with ipragliflozin (50 mg/day) for 16 weeks. Parameters including glycated hemoglobin level, bodyweight, circulating leptin and active ghrelin concentrations, and appetite as assessed with a visual analog scale were measured before and during treatment. Results: Both glycated hemoglobin level (from 7.9 ± 0.8 to 7.1 ± 0.7%) and bodyweight (from 75.2 ± 12.6 to 72.6 ± 12.4 kg) were significantly decreased after treatment for 16 weeks. The fasting serum leptin level was significantly decreased after 2 weeks (from 19.5 ± 13.1 to 18.1 ± 12.4 ng/mL) and remained decreased up to 16 weeks, even after adjustment for bodyweight, whereas the plasma active ghrelin level showed no significant change. The visual analog scale score for hunger was significantly increased at 2 and 8 weeks. Conclusions: The present results suggest that ipragliflozin improved glycemic control and reduced bodyweight, but also reduced serum leptin levels and might thereby have increased appetite. Abstract : Ipragliflozin improves blood glucose levels and body weight in patients with suboptimally controlled type 2 diabetes in 16 weeks. But it also reduces the serum leptin concentration, with this latter effect possibly explaining the observed increase in appetite.
