Dependence of cardiotrophin-1 on biochemical and hormonal factors in patients with comorbid pathology: arterial hypertension, type 2 diabetes mellitus and obesity

Abstract

The prevalence of arterial hypertension, type 2 diabetes mellitus (type 2 DM), and obesity is constantly in-creasing worldwide. Today, a complex of factors, which primarily include chronic emotional stress, pandemics of infectious diseases, military conflicts, have led to a significant increase in chronic non­communicable diseases. The aim of the study. To determine the dependence of Cardiotrophin-1 on a number of biochemical and hormonal indicators in patients with arterial hypertension, type 2 DM, and obesity, representatives of the Ukrainian population. Materials and methods. The study included 211 patients aged 49 to 65 years, who were divided into groups depending on the pathology: patients with arterial hypertension — 49 persons, Group I; patients with arterial hypertension in combination with class 1 obesity — 54 persons, Group 2; patients with arterial hyper-tension in combination with type 2 DM — 57 persons, Group 3; patients with arterial hypertension, type 2 DM, class 1 obesity — 51 persons, Group 4; as well as 20 persons — the Control group. Determination of the content of Cardiotrophin-1, catestatin, leptin, cystatin C, neutrophil gelatinase-asso-ciated lipocalin (NGAL), N­terminal brain natriuretic peptide (NT­proBNP), 25­OH vitamin D (Vitamin D3), blood levels was carried out by enzyme immunoassay on Labline­90 analyzer (Austria), using commercial test systems manufactured by FineTest (ELISA, China), BT LAB (ELISA, China), DBC (ELISA, China), Elabscience (ELISA, Canada), Monobind Inc. (ELISA, USA).Statistical data analysis was performed, using the statistical software package Statistica, 12 (Stat Soft Inc, USA), Microsoft Office Excel 2013. Data are shown as mean (M) and standard deviations (δ). An error of less than 5 % was considered to be significant (p < 0.05). Stepwise regression analysis was used to determine the ex-tent of exposure of the studied indicators to the CTF-1 level, with its effectiveness assessed by one-way analysis of variance (ANOVA).Results. Thus, the study indicates that comorbid patients with arterial hypertension, type 2 DM, and obesity are predicted to develop complications from the cardiovascular system and Cardiotrophin-1 is a marker of their development. In the examined patients as a whole, the level of Cardiotrophin-1 is closely related to the peptide-hormonal complex: catestatin, leptin, cystatin C, brain natriuretic peptide, and lipocalin associated with neutrophil gelatinase. Conclusions: The serum concentration of Cardiotrophin-1 in patients with arterial hypertension in-creases significantly in a progression with the rate of accession of comorbid pathology and its severity.The Cardiotrophin-1 level in patients with comorbid pathology is affected by catestatin, leptin, cystatin C, NT-pro BNP, as well as the level of triglycerides, HDL­C, creatinine, and BMI.Cardiotrophin-1 can be considered as a universal biomarker for the development and progression of cardiovascular disorders in patients with comor-bid pathology of arterial hypertension, type 2 DM, and obesity
