EVALUATION OF THE EFFECTIVENESS OF THE HUMAN GLUCAGON-LIKE PEPTIDE-1 ANALOGUE LIRAGLUTIDE IN PATIENTS WITH GOUT AND METABOLICALLY UNHEALTHY OBESITY PHENOTYPE
Abstract
Introduction. Obesity is a global problem of the XXI century. The most important aspect of metabolic disorders that develop with obesity is a change in the level of serum uric acid (UA) in the blood and the development of gout. Currently, the dynamics of cardiovascular risk factors in patients with obesity on the background of drug therapy is being widely studied.The aim of our study is to study the level of UA, vaspin (VsP), visfatin (VF), omentin (ITLN1), retinol-binding protein-4 (RBP4) in patients with gout and metabolically unhealthy obesity (MNHO) during diet therapy and 3 months of treatment with the drug from the group of human glucagon-like peptide-1 analog (aGLP-1) Liraglutide.Materials and methods: 25 men with gout were examined, the average age was 43.6±7.3 years. Gout was diagnosed according to the classification criteria ACR/EULAR, 2015, Wallace S.L., 1977. Metabolic syndrome was established according to the criteria of GNCA (2013): abdominal obesity - waist circumference ≥ 94 cm in combination with any 2 from the following criteria - an increase in triglycerides (TG) ≥ 1.7 mmol / l; a decrease in high-density lipoproteins (HDL) < 1.0 mmol / l, an increase in low-density lipoproteins (LDL) ≥3.0 mmol / l, blood pressure (BP) ≥ 140/90 mm Hg; increase in plasma glucose ≥ 6.1 mmol / l. At the time of inclusion in the study, all patients had an interictal period of gout. Body mass index (BMI) was calculated using the Quetelet formula: body weight (kg)/height (m²). To assess the type of distribution of adipose tissue, the waist circumference (WT, cm) and hip circumference (HB) were measured with a flexible centimeter tape, with the calculation of the W/H ratio. The concentration of VsP, VF, ITLN1, RBP4 was studied using the enzyme-linked immunosorbent assay method using the kits; the concentration of the level of UA in blood serum and daily urine was studied using the colorimetric method. Liraglutide was injected into the subcutaneous fat of the anterior abdominal wall at a dose of 0.6 mg once a day for the first week. Escalation by 0.6 mg every week was then recommended until a dose of 18 mg per day was reached. Participants then received injections at a dose of 1.8 mg for 3 months. Thus, the observation period was 3 months. Laboratory studies and assessment of anthropometric parameters were carried out initially, as well as after 3 months. The control group consisted of 16 healthy men matched in age. Statistical data processing was carried out using the statistical software package Statistica 13.0.Results. 3 months after treatment, a statistically significant decrease in body weight, BMI and WC was noted (in all cases, p<0.01). Median BMI before treatment was ˗ 38.4 [35.4; 39.2] kg/m², against the background of ongoing therapy - 33.2 [31.4; 34.2] kg/m², and thus the loss of body weight was 23% (p<0.05). Serum UA level decreased by 30.1% (p<0.05) during therapy with a drug from the GLP-1 group. In patients with gout, BMI and regression of obesity were associated with a significant decrease in VsP by 17.2%, VF by 13.8% and RBP4 by 10.4%, and a significant increase in ITLN1 by 12.6%. A direct correlation was established between BMI and WC with the content of VsP, RBP4 and VF in blood serum (correlation coefficients from 0.44 to 0.57, p<0.05) and an inverse correlation with the content of ITLN1 (correlation coefficient -0.29, p<0.05). A direct correlation was found between the serum UA index and the content of VsP, VF, RBP4 (correlation coefficients from 0.31 to 0.49, p<0.05).Conclusion. Patients with gout in combination with MNZO showed a significant increase in serum levels of UA, VsP, RBP4 and VF, against the background of a decrease in the concentration of ITLN1. The use of diet therapy using a drug from the GLP-1 group showed a statistically significant decrease in BMI, WC, serum UA, pro-inflammatory adipokines (VsP, VF and RBP4), and a significant increase in anti-inflammatory cytokines (ITLN1).
