Effect of empagliflozin versus linagliptin on body composition in Asian patients with type 2 diabetes treated with premixed insulin
Abstract
Insulin therapy often increases body weight and leads to visceral fat accumulation. Progression in diabetes is also associated with accelerated loss of muscle mass. Little is known about body composition changes in type 2 diabetes mellitus (T2DM) patients on insulin therapy who use sodium–glucose cotransporter-2 (SGLT2) inhibitors versus dipeptidyl peptidase-4 (DPP4) inhibitors. This study examined the effect of 25 mg of empagliflozin compared with 5 mg of linagliptin for 24 weeks on body weight and body composition in patients with T2DM on premixed insulin. Body composition was assessed with bioelectrical impedance analysis. The mean difference between the linagliptin and empagliflozin groups in terms of mean body weight change from baseline to 24 weeks was − 1.80 kg (95% CI − 2.57, − 1.03). Empagliflozin also significantly reduced muscle mass (− 1.39 kg, 95% CI − 2.49, − 0.29) and total body water (− 1.07 kg, 95% CI − 1.88, − 0.27) compared with linagliptin. Compared to linagliptin, empagliflozin decreased body fat mass more from baseline to week 24, but this was not significant (− 0.31 kg, 95% CI − 1.51, 0.90). Further research on insulin-treated T2DM patients is necessary to investigate the long-term effects of SGLT2 and DPP4 inhibitors on body composition, as well as their effects on muscle strength and physical function.

How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
