Introduction: Assessing the effect of GLP 1 receptor agonist on metabolic control and weight loss in obesity and type 2 diabetes patients.

Description of methods: A retrospective descriptive study involving type 2 diabetes patients and BMI >30 kg/m2, who started treatment with GLP-1-RAs during the years 2012–2014. Variables analyzed: weight and HbA1c at the begging, 6 months, 1 and 2 years; regimen at baseline and after GLP-1-RAs; incidence of withdrawal of treatment.

Results: 125 patients were included (mean age 55.4±9.7 years old; male 58.4%). GLP-1 agonists: exenatide 24.8%, liraglutide 57.6%, 17.6% lixisenatide. HbA1c at baseline: 8.9±1.37%; HbA1c 6 months: 7.7%±1.3; HbA1c 1 year: 7.3%±1.4; HbA1c 2 years: 7.3%±1.3. Start weight: 16.4±106.4 kg; 6 months weight: 101.6±16.5 kg; 1 year weight: 15.7±98.4 kg; 2 years weight: 15.5±97.4 kg. The difference in HbA1c and weight at baseline and 6 months, 1 year and 2 years follow-up statistically significant (P<0.001), not statistically significant difference the first and second years of therapy. 56.8% patients were treated with insulin at start. After addition GLP-1-RAs insulin treatment was finished by 9.9% (45.2% basal bolus therapy who changed baseline insuline and OADs). Therapy discontinued in 25.6% (68.8% in the first-year), the main reason was non-response (75%).

Conclusions: GLP-1 agonist inclusion in type 2 diabetes therapy improves glycemic blood control and loss weight. Improvement already 6 months and holding the first and second year. Treatment helped simplified insulinize, which is reflected in that almost half of those doing intensive treatment could suspend insulin. However, the number of patients we found in whom the treatment brought no improvement was significant, been observed early non-response.
