Impact of 24-week dapagliflozin treatment on body weight, body composition, and cardiac risk indicators of patients with type-2 diabetes mellitus

Abstract

Background/aim: To reveal the impacts of dapagliflozin, a sodium glucose transporter-2 inhibitor (SGLT-2i), on body weight and body composition, cardiovascular risk indices, and carotid intima-media thickness (CIMT). Materials and methods: The data of patients with type-2 diabetes mellitus (T2DM) who applied to Department of Endocrinology and Metabolic Disorders between September 2019 and 2020, and had started dapagliflozin treatment along with their current medications were recorded retrospectively. Body weights, body compositions measured through bioelectrical impedance, and CIMT with T2DM receiving SGLT-2i treatment and medication were measured at weeks 1, 12, and 24 of 42. The visceral adiposity index (VAI), lipid accumulation product (LAP), and atherogenic index of plasma (AIP) were used to determine the lipid measurements and anthropometric values. Results: The mean change in the total body weight and total fat mass was –2.96 and –1.97 kg, respectively (p < 0.001). There was a reduction in total fat mass of 1.23 kg (from 31.4 to 29.3 kg, p < 0.001) and in body fat percentage of 2.5% (from 35.8% to 34.4%, p < 0.001) in the first 12 weeks. A mild increase was observed in both the total fat mass and body fat percentage between weeks 12 and 24, which was not statistically significant (p = 0.783 and p = 0.925, respectively), whereas there was a statistically significant reduction in high-sensitive C-reactive protein (hsCRP), AIP, and CIMT values (p = 0.006, p = 0.035, and p = 0.007, respectively). No changes were observed in the VAI and LAP values (p = 0.985 and p = 0.636, respectively). Conclusion: It was observed that dapagliflozin not only contributes to weight and fat loss but also has positive impacts on cardiovascular and atherosclerotic indicators.
