Annotation. Today, diseases of the cardiovascular system retain their leading position among the incidence in the world. The presence of comorbid pathology in the form of type 2 diabetes mellitus (DM) significantly complicates the course of these diseases, worsening its prognosis. The aim of the study: to analyze the prognostic value of asymmetric dimethylarginine (ADMA) as a marker of recurrent cardiovascular events in patients with acute myocardial infarction with type 2 diabetes for 6 months of follow-up. 120 patients were examined: group 1 – patients with acute myocardial infarction (AMI) in combination with type 2 diabetes mellitus (n=70), group 2 - patients with isolated AMI (n=50). The control group included 20 practically healthy individuals. All patients underwent general clinical and instrumental examinations, on the first day of AMI the level of ADMA was determined using a commercial test system "Human Asymmetrical Dimethylarginine ELISA". Statistical processing of the obtained data was performed using the software package StatSoft Inc, USA – "Statistica 6.0". The analysis of the average level of ADMA showed a significantly higher value of this indicator in patients with AMI in combination with type 2 DM than in patients without concomitant type 2 DM 2.57 times (1.57±0.11 μmol / l and 0.61±0.06 μmol / l, respectively), (p<0,05. ADMA level >1,72 μmol / l in patients with AMI in combination with type 2 DM and >0,69 μmol / l in patients with AMI without concomitant type 2 DM was identified as a predictor of recurrent acute myocardial infarction within 6 months of follow-up. Thus, the level of ADMA was higher in the presence of comorbid pathology in the form of type 2 DM in patients with AMI, reflecting endothelial dysfunction combining disease. It is advisable to further study this indicator of endothelial dysfunction as a predictor of the adverse course of AMI in combination with concomitant type 2 DM.

The aim of the research. Analyze the prognostic value of endothelial monocyte activating polypeptide – ІІ as a marker of recurrent cardiovascular events in patients with acute myocardial infarction with type 2 diabetes mellitus within 6 months of follow-up after a coronary event. Materials and methods. The research involved 120 patients. All subjects were included in 2 groups: group 1 - patients with acute myocardial infarction (AMI) and type 2 diabetes mellitus (DM), group 2 - patients with AMI (n = 50). The control group included 20 healthy individuals. Examination of patients was performed on the basis of the cardiology department for patients with acute myocardial infarction KNP "City Clinical Hospital №27" HMR and the 1st cardiology department of Kharkiv Clinical Hospital by rail №1 branch "Health Center" of the Joint Stock Company "Ukrainian Railways" . The participants of the research on the first day of AMI were determined the level of human endothelial monocyte activating polypeptide – ІІ (EMAP-II) in the serum using enzyme-linked immunosorbent assay using a commercial test system manufactured by Bioassay Technology Laboratory (China) in accordance with the enclosed instructions on enzyme-linked immunosorbent assay "Labline-90" (Austria). General clinical and instrumental examinations were performed on patients who were part of the 1st, 2nd groups and control groups. People who participated in the research were informed about the purpose, objectives, materials and methods of the research by signing an informed consent to participate in it. During the research, measures were taken to ensure the anonymity of each of its participants. Statistical processing of survey results was performed using software package StatSoft Inc USA - "Statistica 6.0". Research results. The average level of EMAP-II in patients who were in the 1st group was 4.54 ± 0.331 ng / ml, the 2nd - 2.74 ± 0.21 ng / ml, in the control group - 1.1 ± 0.037 ng / ml (p <0.05). A recurrent cardiovascular event in the form of recurrent AMI occurred in 19 patients (27.14%) who were part of the 1st group and in 7 patients (14%) who belonged to the 2nd group. The research found that the value of EMAR-II> 5.42 μmol / l in patients with AMI in combination with type 2 diabetes and> 2.64 μmol / l in patients with AMI without concomitant type 2 DM is a predictor recurrence of AMI within 6 months of follow-up after a coronary event. Based on the results of the research, a multifactor logistic regression model for the prognosis of recurrent AMI in patients with AMI in combination with type 2 DM was developed using EMAR-II for 6 months of follow-up after a coronary event. Conclusions. Thus, the level of endothelial monocyte activating polypeptide – ІІ in patients with acute myocardial infarction correlates with the presence of comorbid pathology in the form of type 2 diabetes mellitus, having the highest level in its presence, reflecting endothelial dysfunction that pathogenetically combines these diseases. According to the above, to date, the question remains about the prognostic value of endothelial monocyte activating polypeptide – ІІ in acute myocardial infarction in patients with concomitant type 2 diabetes mellitus during the 6-month follow-up period after a cardiovascular event. It is advisable to further research the rate of endothelial dysfunction - endothelial monocyte activating polypeptide – ІІ as a predictor of recurrent cardiovascular events in patients with acute myocardial infarction in combination with concomitant type 2 diabetes mellitus within 6 months after the coronary event.

The purpose of the study was to determine the prognostic value of asymmetric dimethylarginine in the development of complications in the hospital period of acute myocardial infarction with ST segment elevation in patients with type 2 diabetes mellitus. Material and methods. The study design consisted of 120 patients. They were divided into 2 groups. Group 1 consisted of patients with acute myocardial infarction and concomitant type 2 diabetes mellitus (n=70), group 2 included patients with acute myocardial infarction without concomitant type 2 diabetes mellitus (n=50). Patients of both groups matched on age and sex (60 men (50%) and 60 women (50%); their average age was 66.35±0.91 years, р<0.05). The control group consisted of 20 almost healthy people, among them 12 women (60%) and 8 men (40%) (average age was 45.17±2.88 years). The patients were divided into 3 tertiles according to the level of аsymmetric dimethylarginine (ADMA): ADMA ⩽1.45 μmol/l – 1st tertile; 1.45 μmol/l< ADMA ⩽1.98 μmol/l - 2nd tertile; ADMA >1.98 μmol/l - 3rd tertile. Results and discussion. The obtained results showed that the level of ADMA in patients with acute myocardial infarction in combination with type 2 diabetes was by 2.57 times (p <0.05) higher compared to patients without concomitant type 2 diabetes. In particular, the ADMA level was at 1.57±0.11 μmol/l in patients with acute myocardial infarction in combination with concomitant type 2 diabetes, while in patients with acute myocardial infarction without concomitant type 2 diabetes it was at 0.61±0.06 μmol/l. The ADMA value at >1.13 μmol/l in patients with acute myocardial infarction in combination with type 2 diabetes is a predictor of acute left ventricular failure. The ADMA tertiles were used to determine the acute myocardial infarction severity class based on the Killip scale. It is noteworthy that severer classes of acute myocardial infarction on the Killip scale were observed in a patient whose ADMA value belonged to the 3rd tertile group. We determined the ADMA value of A >2.08 μmol/l in patients with acute myocardial infarction in combination with type 2 diabetes, which was a predictor of a life-threatening condition of cardiogenic shock. Conclusion. The asymmetric dimethylarginine exhibits the following predictor properties: in relation to the development of acute left ventricular failure – at >1.13 μmol/l; in relation to the development of cardiogenic shock - at >2.08 μmol/l during the hospital period of acute myocardial infarction with ST-segment elevation in patients with concomitant type 2 diabetes. It is advisable to continue studying the marker of endothelial dysfunction (asymmetric dimethylarginine) as a predictor of adverse myocardial infarction in combination with concomitant type 2 diabetes

Purpose — to identify the possibility of improving the outcome of multimodality treatment of acute myocardial infarction (AMI) in type 2 diabetes mellitus (DM) patients by use of a succinate-containing drug.Materials and methods. The results of examination and treatment of 86 men aged 40 to 70 years with clinical diagnosis of AMI and concomitant type 2 DM were analyzed. The patients were split into two groups depending on use of the succinate-containing drug. Patients of the control group (38 men, 58.3±7.1 years old) received the standard treatment that included percutaneous coronary intervention (PCI). In the main group under study (48 men, 57.6±7.6 years old), the standard therapy complex was complemented with administration of a succinate-containing drug (1.5% succinic acid solution), which was administered first 30–60 minutes prior to PCI intravenously at a dose of 10–12 ml/kg; then, daily once a day, for 5 days at a dose of 5–6 ml/kg. Peculiarities of the AMI clinical course, dynamics of myocardial contractility, values of acid-base balance (ABB), glucose and lactate content, lipid peroxidation (LPO) and antioxidant system (AOS), rheological properties of the blood were evaluated.Results. During AMI type 2 DM patients developed compensated metabolic lactic acidosis and oxidative distress that manifested in considerable activation of LPO and insufficient activity of the enzymatic component of AOS, blood viscosity grew, elasticity of red blood cells fell. Decreased local and global myocardial contractility was noted as well. During PCI in this category of patients, cardiac rhythm disorders developed in 47.4% of cases, 23.7% of which were life threatening, such as multifocal ventricular extra systole and ventricular fibrillation. Conclusion. Administration of a succinate-containing drug during performance of PCI provided correction of the lipid peroxidation processes and rheological properties of the blood in the population studied, facilitated improvement of left ventricle’s systolic and diastolic function, reduced the risk of reperfusion complications.

ObjectiveThe aim of this study was to evaluate any association between metformin use and oncological outcomes of cervical cancer in patients with type 2 diabetes mellitus (DM).MethodsWe retrospectively identified 248 patients with cervical cancer with type 2 DM who received primary treatment between 2004 and 2015. The clinicopathological characteristics and oncological outcomes were collected and analyzed. The patients were then separated into metformin use (n = 118) or non–metformin use (n = 130) groups.ResultsWith a median follow-up of 2.85 years, patients who were given metformin had lower recurrence rate than patients who did not receive metformin (P = 0.011). The 5-year disease-free survival (DFS) and overall survival (OS) were 81.55% and 93.27% in the metformin use group, and 65.06% and 86.82% for the non–metformin use group, respectively. In multivariate analysis, non–metformin use (hazard ratio [HR], 1.89; P = 0.037), baseline hypertension (HR, 2.52; P = 0.005), and stage (HR for stage II vs I, 3.48; HR for stage III vs I, 6.45; P = 0.01) were independent adverse prognostic factors for DFS, whereas the statistically significant independent prognostic factors for OS were age (HR for age >65 vs ≤50, 3.86; P = 0.044) and stage (HR for stage III-IVA vs I-II, 3.45; P = 0.007).ConclusionsOur findings demonstrate that metformin use is associated with improved DFS, but not in OS in patients with cervical cancer with type 2 DM. Further large-scale and long-term follow-up studies are warranted to confirm the antitumor effects of metformin.
