[The relation of the activity of postheparin lipoprotein lipase with the CBC parameters in patients with acute coronary syndrome].

The aim of presented investigation was to study of the relation of the activity of postheparin lipoprotein lipase (LPL) with the blood test parameters in patients with acute coronary syndrome(ACS) during first 6-12 hours after appearance of acute anginous pain. 47 patients with the disease of coronary arteries (DCA) have been investigated. Acute form of ACS was revealed in 27 patients (mean age--62.9+/-11.7 years), chronic form--in 20 patients (mean age 67.9+/-14.0 years). The study was carried out in the first 6-12 hours after appearance of acute anginous pain. Control group consisted of 23 healthy subjects (mean age--37.5+/-8.9 years). Postheparin activity of LPL has been determined in whole cohort by potentiometric method. Blood test was carried out by standard method. The acute coronary syndrome was confirmed by electrocardiographic findings. In ACS group the activity of LPL significantly correlated inversely with the value of leukocytes (r=-0.4022, p=0.038), stab (r=-0.4808, p=0.011) and segmental leukocytes (r=-0.5853, p=0.001), erythrocyte sedimentation rate (r=-0.4188, p=0.030). Corning to the comparative analysis of chronic and acute forms of DCA, the activity of LPL was significantly lower in patients with chronic form compared to the acute form (p=0.043). Therefore, based on the obtained data it should be concluded that in 6-12 hours after development of acute coronary syndrome during worsening the inflammatory reaction (which reflected on the parameters of blood test) together with endothelial dysfunction it is expressed the decrease of the activity of endothelial enzyme LPL.

[The dependence of changes of parameters of metabolic syndrome features on the reduction of degree of insulin resistance during lifestyle intervention].

The aim of our investigation was to study the dependence of changes of parameters of metabolic syndrome (MS) features on the reduction of degree of insulin resistance during lifestyle intervention--balanced diet and moderate exercise. 33 patients with MS have been investigated (mean age--49.1+/-8.7 years). MS was confirmed by WHO definition of 2002. All parameters of MS features have been determined baseline and after 6 months of study initiation. Balanced diet (restriction of easy-digestible carbohydrates and lipids and consumption of products with high cellulose content) and moderate exercise (60 min. walking three times per week) have been prescribed to all patients. After 6 months IR index was decreased from 3.6+/-0.7 to 2.6+/-0.4 (p<0.001). Investigated subjects were divided on two groups: I group consisted of patients HOMA-IR index of whom after 6 months decreased by magnitude less than 1.0 (n=19); and II group--patients HOMA-IR index of whom after 6 months decreased by magnitude greater or equal 1.0 (n=14). In spite of similar reduction of body mass and waist circumference, the parameters of carbohydrate and lipid metabolism in II group decreased significantly sharply than in I group. The more positive changes of metabolic parameters of MS features during lifestyle intervention strongly depend on the degree of reduction of insulin resistance which has to become the main strategic target during MS treatment.

[Levels of uric acid in serum in patients with metabolic syndrome].

The aim of our investigation was to study the peculiarities of serum uric acid (UA) levels in patients with metabolic syndrome (MS) and without it, also correlations between UA and parameters of MS features. 41 patients (mean age - 37,8+/-13,7 years) have been investigated. MS was defined by definitions of WHO (2002), ATPIII and Society of Georgia Endocrinologists (SGE). Exclusion criterion served the gout. Levels of all parameters of MS features and serum UA have been determined. MS was diagnosed in 48,7% of cases. Study group consisted of these patients, and control group - patients without MS. Serum UA levels were significantly higher in the study group in comparison with the control (6,6+/-1,4 vs. 5,4+/-1,3 mg/dl, p=0,007; respectively). In main group the cases of hyperuricemia have been documented significantly frequently than in control (65,0% vs. 33,3%, p=0,043; respectively). Obtained results shown that UA levels significantly higher and hyperuricemia cases significantly frequent at MS, which have to be taking into account during symptomatic treatment of patients.

[Peculiarities of postprandial activity of lipoprotein lipase in coronary heart disease].

The aim of investigation was to study the peculiarities of activity of lipoprotein lipase (LPL) and serum lipid spectrum after fat test meal in patients with coronary heart disease (CHD). 42 persons have been investigated. The main group consisted of 27 patients with CHD (13 males, 14 females). 15 almost healthy subjects (5 males, 10 females) were unified in control group. Parameters of lipid metabolism have been studied by biochemical technique both in basal state and at 3 hours after standard test meal. In parallel, the levels of LPL activity have been investigated by potentiometric method. The values of LPL activity in patients with CHD both in basal and in postprandial states were significantly lower in comparison with analogous values of control subjects. Its postprandial level in CHD patients did not change significantly (percentage increment was 1,0+/-0,9%), but in control group - was increased by 22,3+/-4,4%. Obtained results suggest that LPL activity is not increased at increased postprandial atherogenic lipemia in patients with CHD. LPL activity should be considered as a metabolic marker of atherogenesis and CHD.

[The status of redox system in patients with chronic autoimmune thyroiditis].

The aim of present investigation was to study redox processes and to establish state of blood oxidative and antioxidant systems in patients with chronic autoimmune thyroiditis (CAT). 19 patients with CAT (2 males, 17 females; mean age 35,3+/-14,8 years) have been randomly investigated, of which 3 patients (15,8%) had hypothyroidism, 11 (57,9%) - euthyroidism and 5 (26,3%) - hyperthyroidism. Control group consisted of 10 practically healthy subjects (2 males, 8 females; mean age 41,1+/-11,7 years). The parameters of blood redox-system were investigated by electron-paramagnetic resonance method (EPR). The value of ceruloplasmin in patients with CAT was significantly higher than in control group (20,0+/-2,0 mm/mg vs. 16,0+/-1,1 mm/mg, p<0,001); EPR-signal of Fe3+ - transferrin in main group was also significantly higher (18,5+/-1,3 mm/mg vs. 22,0+/-0,9 mm/mg, p<0,001); values of nitric oxide in both groups were almost identical. EPR-signals of methemoglobin significantly correlated with thyroid volume (r=0,5421, p=0,016). These changes demonstrate possible relationship between CAT and blood redox system. It should be supposed that the introduction of antioxidant preparations will improve CAT pathogenetic therapy.

[The status of redox system in patients with Graves' disease].

The aim of our investigation was studying the redox processes, the establishment of state of blood oxidative and antioxidant systems in patients with Graves' Disease (GD). 19 with diffuse-toxic goiter have been investigated. Control group included 10 practically healthy subjects. The parameters of blood redox-system were investigated by electron-paramagnetic resonance method (EPR). In GD group hypothyroidism was diagnosed in 7 patients (36,8%), euthyroidism - in 7 patients (36,8%) and hypothyroidism - in 5 (26,3%). The value of ceruloplasmin in main group was significantly higher than in the control (18,6+/-1,3 mm/mg vs. 16,0+/-1,1 mm/mg, p<0,001); EPR-signal of Fe(3+)-transferrin in main group was also significantly higher (19,2+/-1,2 mm/mg vs. 22,0+/-0,9 mm/mg, p<0,001); values of nitric oxide in both groups were almost identical. EPR-signals of Mn(2+) ions significantly correlated with thyroid volume (r=0,5461, p=0,016), NO - with antibodies to thyroglobulin (r=0,5750, p=0,010). These changes demonstrate possible relationship between autoimmune diseases and redox-system.

[Some peculiarities of the activity of postheparin lipoprotein lipase and parameters of lipid metabolism at ischaemic heart disease].

The study of the relation of atherosclerosis with lipid metabolism (LM) remains still very important. The aim of presented work was the investigation of peculiarities of lipoprotein lipase (LPL) and LM at IHD in different age and sex groups; also the search of possible relation of LPL activity changes with myocardial contractility function and coronarography data at IHD. 47 patients (15 females, 32 males) with IHD were investigated. They were divided on 3 groups: 1 -<50 years (n=14); 2 - 50-59 years (n=14); 3 - >/=60 years (n=19). Patients were investigated by coronarography and echocardiography. Main parameters of LM were determined by enzyme-linked immunoassay. LPL activity was defined by potentiometric method. It was observed significant difference between levels of LPL activity of different age groups (p(1-2)=0,027, p(1-3)<0,001, p(2-3)=0,035). Significant difference in this parameter by sex feature did not observed. The degree of damage in anterior descending branch of left coronary artery negatively correlated with LPL activity (r=-0,5598, p<0,001). Ejection fraction (EF) revealed positive correlation with LPL activity (r=0,4362, p=0,002). The degree of damage of left coronary artery, in particular, medial segment of circumflex branch correlated with LM parameters. EF positively correlated with high-density lipoprotein cholesterol blood level (r=0,3548, p=0,036). LPL activity in patients with IHD significantly decreased with aging. From obtained results it will be supposed that LPL activity and LM parameters influences on the damage degree, basically, left coronary artery.
