[Changes in weight, body composition, metabolic parameters and vitamin D in subjects with grade 3 and 4 obesity treated with liraglutide 3 mg].

Introduction: grade 3 and 4 obesity is a chronic and progressive disease. Liraglutide 3 mg could be an effective adjuvant therapy in these subjects. Objectives: to evaluate changes in weight loss, body composition, metabolic parameters and vitamin D levels in subjects with grade 3 and 4 obesity treated for 8 months with liraglutide 3 mg. Methods: a total of 67 subjects with a BMI ≥ 40 kg/m2 had anthropometric parameters, body composition, metabolic parameters and vitamin D levels determined at baseline and after 8 months of treatment with liraglutide 3 mg. Results: a significant reduction in weight, BMI and abdominal circumference was evident after 8 months of treatment with liraglutide (p < 0.001), with a mean percentage of weight loss of 13.04 % and a mean weight loss of 14.99 kg at the end of the intervention. The final body composition data showed a significant improvement in the percentage of fat and fat mass (kg) (p < 0.001). The average loss of muscle mass was 2.02 kg (p = 0.213). The healthy visceral fat index (VGI) (< 13) increased to 67.17 % (p < 0.001) at 8 months. There was a significant reduction in blood pressure (p < 0.001) and an improvement in the biochemical variables studied. There was a significant increase in 25-OH vitamin D (p < 0.001) at the end of the intervention. Conclusions: Treatment with liraglutide was safe and effective in patients with obesity with a positive impact on weight loss, vitamin D levels and other cardiovascular risk factors.
