Diabetes type 2 (CD2), which develops mainly against visceral obesity, is socially significant disease, reduction of losses from which is priority in development of modern medicine. Glucagon-like peptide-1 receptor agonists (aGPP-1) is one of few groups of antidiabetic drugs that allows to reduce not only glycemia, but also weight with CD2. Taking into account predictors of response to therapy will allow highest probability to reach targets while maintaining safety of treatment, optimize recommendations for appointment of aGPP-1 as much as possible. Aims: to assess dynamics of metabolic parameters, to determine predictors of reduction in blood glucose, body weight and other metabolic parameters in AGPP-1 therapy in patients with type 2 diabetes with body mass index (BMI) >35 kg/m. Material and methods. Study involved 33 patients (10 men, 23 women) who had been treated with aGPP-1, planned period of observation for 24 weeks. Early termination ofparticipation of 3 patients (1 - due to development ofpancreatitis, 2 - due to lack of financial opportunity to purchase the drug). Accordingly, 30 patients (10 men, 20 women) were included in final analysis. Examination consisted of survey, physical examination with measurement of anthropometric, clinical parameters, filling questionnaires. Data were evaluated initially and after 24 weeks of treatment. Results. Study found that patients who achieved weight loss > 5% initially had higher BMI (p = 0.028), lower GLP-1 (p = 0.036), had lower level of ghrelin after sample with standard breakfast (p = 0.022). There was trend (p = 0.071) to greater decrease in BMI in patients with restrictive type of eating behavior compared to patients who had mixed type. More pronounced decrease in glycemia was noted in patients who had higher fasting plasma glucose level at inclusion (p = 0.001). Dynamics of HbA1C was better in patients with initially higher GLP-1 (p = 0.016) and higher levels of glycemia (p = 0.001). Also, in examined patients, there was statistically significant decrease in level of triglycerides, blood pressure by end of treatment period. Conclusions. Results indicate that there are different predictors for weight loss, glycemia and blood pressure in aGPP-1 therapy. In addition to metabolic parameters, level of orexigenic and anorexigenic hormones and psycho-social characteristics ofpatients help to estimate expected effect of therapy for ARP1. When predictors are identified, predictors of weight loss and carbohydrate metabolism compensation should be studied separately. Identification of response predictors is necessary to optimize indications for prescribing this group of drugs with CD2.
