THE ROLE OF A NEW BIOMARKER GROWTH DIFFERENTIATION FACTOR 15 IN PROGNOSIS OF PATIENTS WITH ACUTE CORONARY SYNDROME AND TYPE 2 DIABETES MELLITUS

Numerous studies confirm worse results in diabetic patients with acute coronary syndrome (ACS) compared with non-diabetic patients. Different mechanisms underlie the adverse outcomes of ACS and diabetes mellitus. In this connection, a special place is occupied by the study of new biomarkers that reflect the complex pathogenic processes in these patients. Purpose: to investigate the role of the biomarker GDF 15 in prognosis of adverse outcomes in type 2 diabetes mellitus (DM2T) patients with ACS. Materials and methods: 73 patients with different forms of ACS were screened. Levels of biomarkers: GDF 15, N-terminal pro brain natriuretic peptide (NT-pro BNP) and C-reactive protein (C-RP) were determined. The follow up period was 1 year. Endpoint was defined as lethal outcome. Results: significant differences in GDF 15 level has been found, prognostic value of GDF 15 was estimated in patients with DM2T, using a ROC-analysis. Threshold level of GDF 15 has been determined as 3894 pg/ml, with sensitivity of 64 % and specificity of 75 %. Conclusion: Patients with ACS and DM2T more often had a history of different cardiovascular diseases and risk factors compared to patients without diabetes. GDF 15 level was significantly higher in patients with ACS who had history of DM2T

ALLELE STATUS OF ALDOSTERONE SYNTHASE (CYP11B2) GENE POLYMORPHISM AND CARDIAC REMODELING AFTER ST SEGMENT ELEVATION MYOCARDIAL INFARCTION

Aldosterone plays an important role in the development of reparative and reactive fibrosis and cardiac remodeling (CR) after myocardial infarction. The objective of the study is to investigate the structural and functional parameters of the myocardium, heart rate variability (HRV), exercise intolerance, levels of sST2 in association with polymorphism of CYP11B2 gene of aldosterone-synthase in ST-myocardial infarction (STEMI) patients during a 6-months follow-up period. 85 STEMI patients were enrolled: 68 (80 %) male and 17 (20 %) female, mean age was 58,94 ± 10,16 years. Examinations were performed twice: during 1–3 days after PCI with infarct-related artery stenting and included clinical assessment, ultrasound diagnostic, immunofermentative blood analyses (sST2), polymerase chain reaction in real time (polymorphism –T344C of the CYP11B2 gene). After 6-months of observation, 57 patients were reexamined – clinical assessment, ultrasound diagnostic, HRV were performed. CYP11B2 TT-genotype in 6 months after STEMI is associated with a maladaptive character of after infarction remodeling

A comparative study on the effectiveness of application of different types of biological matrixes on mandibular alveolar mucosa lesion healing

Periodontal diseases is one of the most relevant and important problem in modern dentistry due to their increasing prevalence in population, association with the occurrence of focus of chronic infection, progressive development and irreversibility which, in case of severe damage of periodontal tissues, eventually leads to a loss of the number of teeth. All of the named factors eventually lead to the development of irreversible inflammatory-dystrophic and destructive changes in periodontal tissues. During the recent years the method of guided tissue regeneration that uses membranes is being successfully used for the treatment of periodontal diseases. A comparative study on the mandibular alveolar mucosa lesion healing during application of different types of biological matrixes containing decellularized amniotic membrane, decellularized amniotic membrane in combination with platelet-rich plasma (PRP) growth factors, and decellularized amniotic membrane in combination with PRP growth factors and hyaluronic acid was performed. The study proved the acceleration of the processes of wound area reduction. Under experimental conditions, the wound healing lasted from day 3 to day 5 of the study; however, the rate of reduction of the wound area was slower, which indicates an alterative stage of the acute inflammatory process. During days 5 – 7 (stage of regeneration, the 2nd phase of wound process) the wound area reduced rapidly and by day 14 a complete epithelization of the surgical wound was observed in all groups using decellularized amniotic membrane. In the group using the combination of PRP growth factors and hyaluronic acid the epithelization of wound was already observed on the day 5. In the control group healing occurres with scar formation
