Background: For the growing numbers of obese elderly with diabetes, the glucagon-like peptide-1 (GLP-1) receptor analogue (liraglutide) appears a safe way to promote and maintain substantial weight loss. Given this background, the aim of this study was to assess the effect of the liraglutide treatment, at doses up to 3.0 mg per day, on the body composition, focusing on sarcopenia, in overweight and obese elderly with type 2 diabetes mellitus (T2DM). Methods: A perspective study was carried out in overweight and obese T2DM patients with HbA1c equal to 7.0 % (53 mmol/mol) ~10.0 % (86), under 3-month treatment (at least) of maximal dose of metformin at stable regime, and additional liraglutide at doses up to 3.0 mg per day. Body composition markers such as skeletal muscle index (SMI), android and gynoid fat mass, and arms and legs fat free mass, was measured by dual-energy X-ray densitometry (DXA) at baseline and after 24 weeks of liraglutide treatment.

We noted a median decrease in BMI (−0.78 kg/m2), weight (−2000 g), fat mass (−1498 g) and android fat (−0.9 %), and a increase in SMI (+0.03 kg/m2) from baseline. Glycemic control also improved, with a median change HbA1c of −0.80 %. Conclusions: Twenty-four weeks of liraglutide treatment was associated with reductions in fat mass and android fat.

Abstract

Background: For the growing numbers of obese elderly with diabetes, the glucagon-like peptide-1 (GLP-1) receptor analogue (liraglutide) appears a safe way to promote and maintain substantial weight loss. Given this background, the aim of this study was to assess the effect of the liraglutide treatment, at doses up to 3.0 mg per day, on the body composition, focusing on sarcopenia, in overweight and obese elderly with type 2 diabetes mellitus (T2DM). Methods: A perspective study was carried out in overweight and obese T2DM patients with HbA1c equal to 7.0 % (53 mmol/mol) ~10.0 % (86), under 3-month treatment (at least) of maximal dose of metformin at stable regime, and additional liraglutide at doses up to 3.0 mg per day. Body composition markers such as skeletal muscle index (SMI), android and gynoid fat mass, and arms and legs fat free mass, was measured by dual-energy X-ray densitometry (DXA) at baseline and after 24 weeks of liraglutide treatment. Glucose control was also carried out by glucose and HbA1c. Results: Nine subjects (male/female 6/3, mean age 68.22 ± 3.86 years, BMI 32.34 ± 4.89 kg/m2) were evaluated. We noted a median decrease in BMI (−0.78 kg/m2), weight (−2000 g), fat mass (−1498 g) and android fat (−0.9 %), and a increase in SMI (+0.03 kg/m2) from baseline. Glycemic control also improved, with a median change HbA1c of −0.80 %. Conclusions: Twenty-four weeks of liraglutide treatment was associated with reductions in fat mass and android fat. In addition, in order to prevent sarcopenia, it preserved the muscular tropism.
