ABSTRACT
AIM: to study the renin-angiotensin-aldosterone-system (RAAS) in patients with polymorphic variants of the vitamin D receptor gene (VDR), arterial hypertension (AH) and obesity. MATERIALS AND METHODS: We included in this study 98 patients with stage II-III AH and obesity (33 men, 65 women, mean age 61.1±9.9 years and BMI 43.3±5.0 kg/m2). The VDR gene study included genotypes TaqI, BsmI, FokI. After identification of TaqI, BsmI, FokI VDR gene sites we carried out measurements of levels of RAAS markers. RESULTS: We revealed an associative relationship between the presence of allele G of the BsmI site, C/C homozygosity of FokI site of VDR gene and presence of AH in patients with obesity. An increase of renin level was noted only in the homozygous T/T genotype of FokI, no differences in the concentration of aldosterone and angiotensin were detected between any of the studied genotypes. CONCLUSION: Polymorphic alleles and genotypes of the VDR gene can be used as predictors of AH development in obese patients with subsequent characterization of the state of the RAAS system.

Patients suffering from food allergy/food intolerance of eggs need alternative products that do not cause allergic reactions. The purpose of the research: to evaluate guinea fowl egg and meat tolerance among children with chicken egg allergy. There has been conducted single-centre prospective research into intolerance of the products. Appearance or increase in skin or gastrointestinal allergic symptoms was registered; the concentration of specific IgE antibodies against chicken egg and meat in blood serum was assessed. As alternative products, the children were offered guinea fowl egg and meat; these products were given to them during 14 days. In the research 40 children (23 girls and 17 boys) from the age of 8 months to 1.5 years old took part; all children were diagnosed with atopic dermatitis, one of its triggers was chicken egg. Exacerbation of skin allergy was connected with eating chicken egg, which was confirmed by the results of the allergy examination. 28 (70.0%) children were diagnosed as having the mild form of atomic dermatitis, while 12 (30.0%) patients had the moderate form of atomic dermatitis. At the beginning of the research the patients were divided into 2 equal groups (each group of 20 patients). The first group consisted of the children aged 8 moths - 1.5 years old who received 1/2 guinea fowl egg every other day. The second group consisted of the patients aged 1.5-3 years old who received 60-90 grams fowl egg meat per day. The research has revealed that the children showed tolerance of guinea fowl egg and meat, the majority of the patients did not experience any skin or gastrointestinal allergic reactions. It has also been shown that at the end of the research the majority of the children (73.3%) had a decrease in concentration of specific IgE antibodies against chicken egg and meat in blood serum. According to the allergy examination, 8 (26.7%) children experienced an increase in skin sensitization to chicken egg and meat, which coincided with exacerbation of skin allergy. Thus, the examined products can be used as alternative products for those children who suffer from food allergy/food intolerance of chicken egg and meat.
ABSTRACT
Nanosized colloidal silver (NCS) with primary nanoparticles (NPs) size in the range of 10-80 nm in aqueous suspension was administered to rats with initial weight 80±10 gfor the first 30 day intragastrically and for lasting 62 days with the diet consumed in doses of 0.1; 1.0 and 10 mg/kg of body weight b.w) per day based on silver (Ag). The control animals received deionized water and carrier of NPs - aqueous solution of stabilizer polyvinylpyrrolidone. Activity (Vmax) was determined in liver of microsomal mixed function monooxygenase isoforms CYP 1A1, 1A2 and 2B1 against their specific substrates, the activity of liver conjugating enzymes (glutathione-S-transferase and UDP-glucuronosyltransferase) in the microsomal fraction and a cytosol, and the overall and non-sedimentable activities of lysosomal hydrolases. In blood plasma there were evaluated malonic dialdehyde, PUFA diene conjugates, in erythrocytes - the activity of antioxidant enzymes. A set of standard biochemical indicators of blood serum was also determined. The studies revealed changes in a number of molecular markers of toxic action. Among them - the increase in the activity of key enzymes I and II stages of detoxification of xenobiotics, indicating its functional overvoltage; reducing the activity of glutathione peroxidase (GP), the total arylsulfatase A and B, ß-galactosidase (in the absence of changes in their non-sedimentable activity), levels of uric acid, increased alkaline phosphatase activity. These changes occurred mainly at the dose Ag of 10 mg/kg b.w., except for the GP to which the threshold dose was 1 mg/kg b.w. No significant changes in the studied markers in a dose Ag 0,1 mg/kg b.w. were identified. Possible mechanisms of the toxic action of silver NPs are discussed.

The aim of the study was to develop and evaluate the effectiveness of personalized therapy forpatients with diabetes mellitus type 2 (DM) and obesity based on the study of rs5219 polymorphism of KCNJ11gene. The study involved 120 women with DM and obesity I-II degree. Genotyping was performed in patients using allele-specific amplification with the detection in real time. Depending on the genotype of KCNJ11 gene patients with DM and obesity received different treatment and were divided into 2 groups (40 patients in each): group A (C/T genotype) received standard low-calorie diet + metformin 2000 mg/day and group B (T/T genotype) received a personalized diet + vitamin-mineral complex (VMC) + metformin 2000 mg/day. Results of the study of rs5219 polymorphism of KCNJII gene in patients with,DM and obesity have shown that 49% of them were carriers of the mutated T allele in the heterozygous form and 37% - in the homozygous variant. It has been found that reducing of calories in a diet promoted weight loss in patients with DM and obesity mainly due to lean body mass in Group A and in Group B - mainly due to the fat component. A significant decrease in blood glucose under complex therapy was observed in both groups. However, after treatment in group B blood glucose levels were significantly lower than in group A. Thus, personalized therapy of patients with DM and obesity should be based on molecular genetic studies that will allow to improve the efficiency of therapeutic measures in these diseases.

Aim of investigation: The aim of the research is to study the clinical course of hepatitis C in children with different variants of the gene polymorphism of IL-28B. Materials and methods: We observed 94 children (46 girls and 48 boys) with chronic hepatitis C (CHC) in age from 3 to 17 years (mean age 10 years). There were significant differences in the distribution of allele frequencies in children with chronic hepatitis C and in the population. In children with chronic hepatitis C significantly increased the incidence of the T allele at the locus of the gene IL-28B rs12979860 C>T, which makes it possible to consider it as a predictor of antiviral therapy ineffective. Results: When analyzing the frequency of occurrence of a polymorphic variant T>G [rs8099917] IL-28B gene in children with chronic hepatitis C and healthy children revealed no differences in the distribution of alleles. Conclusion: Personalized approach to the appointment of HCV antiviral therapy in children is to carry out genetic studies to determine on the basis of predictive features of the course of HCV in children during the treatment.

Objective - To evaluate the effect of diet therapy with the inclusion of specialized food product with a modified carbohydrate profile (fruit jelly) on glycemic and metabolic parameters in patients with type 2 diabetes mellitus. The study included 45 patients (aged 35 to 69 years) with type 2 diabetes with concomitant obesity I-III degree. The study was conducted in two stages. The first phase evaluated the effect of jelly intake on postprandial glycemia with determination of blood glucose levels on an empty stomach and 30, 60, 120 and 180 minutes after consumption of fruit jelly with maltitol, pectin and sublimated raspberry juice and traditional marmalade with fructose (control), containing 25 g of digestible carbohydrates. In the second phase the effectiveness of combination therapy during 2 weeks of the inclusion of fruit jelly with a modified carbohydrate profile in a standard hypocaloric diet (1550 kcal/day) has been assessed. It has been shown that the dynamics of postprandial glycemia in patients with type 2 diabetes after the consumption of fruit jelly with a modified carbohydrate profile was comparable to the dynamics of blood glucose after eating traditional marmalade with fructose. Inclusion of fruit jelly with a modified carbohydrate profile in the standard diet therapy of patients with type 2 diabetes during 2 weeks was accompanied by positive dynamics of carbohydrate and lipid metabolism, as well as a decrease in the content of lipid peroxidation products in blood plasma: reducing the level of conjugated dienes and malondialdehyde averaged 15.2 and 17.4% from baseline (p<0.05), respectively, while content of lipid peroxidation products in blood plasma did not changed in patients from the control group.

The prevention, diagnosis and treatment of diseases associated to obesity require a qualitative increase of efficiency. There are still disputable questions about diagnostic significance of some molecules, including genomic, proteomic and metabolomic biomarkers. We observed 72 obese patients (20 men and 52 women, mean age--41.3 +/- 2.5) and performed ultrasound elastography and ultrasound of liver. We have identified two groups of patients: Group 1 consisted of 50 obese patients without complications (BMI 43.2 +/- 0.6), group 2 consisted of 22 patients with obesity complicated with nonalcoholic fatty liver disease (BMI 45.8 +/- 2.3). Determination of the adipokines (adiponectin, ghrelin, resistin, visfatin, and apelin), cytokine (interleukin--6, TNFalpha) oxidized lipoproteins (oxLDL), adhesion molecule sICAM (soluble intercellular cell adhesion molecule), fatty acid transporter L-FABP in serum was performed by ELISA. The study of the lipid metabolism involved determination of the concentration of total cholesterols, triglycerides, low and high density lipoproteins (LDL and HDL) by turbidimetry and spectrophotometry by analyzer. In addition, we conducted analysis of polymorphic alleles epsilon2, epsilon3, episolon4 of ApoE gene using polymerase chain reaction. Our data indicate that reducing the concentration of adiponectin (0.46-1.71 mcg/ml), increasing the level of glucose (5.57-6.25 mmol/l), triglycerides (2.06-3.94 mmol/l), TNFalpha (5.07-16.68 pg/ml) and L-FABP (11.62-23.76 pg/ml) are predictors of nonalcoholic fatty liver disease in obese patients, and the presence of genotype epsilon3/epsilon4 of ApoE gene is a poor prognostic marker of severity of nonalcoholic fatty liver disease.

Currently there is no extensive research of metabolic disorders in obese patients with atherosclerosis, including the study of genomic, biochemical, immune and other markers. Therefore, the aim of the study was to identify the genomic, proteomic and metabolic predictors of atherosclerosis in obese patients. We evaluated condition of the cardiovascular system of the 100 obese patients aged 18 to 66 years, which were divided in two groups of patients: Group 1 consisted of 50 obese patients without vascular pathology, 2nd group consisted of 50 patients with obesity, complicated by atherosclerosis. We carried out a study of the lipid metabolism and analysis of polymorphic alleles ε2, ε3, ε4 of the ApoE gene by PCR. Our data showed that clinically significant predictors of atherosclerosis in obese patients are homozygous genotypes ε2/ε2 of the ApoE gene, increased blood serum level of triglycerides, oxidated LDL, interleukin-6, adhesion molecules SICAM, L-FABP and adiponectin reduction.

The influence of diet inclusion of vitamin and mineral complex (VMC), potassium and magnesium in the form of asparaginate on micronutrient status, body composition and biochemical parameters in patients with diabetes mellitus type 2 (DM2) has been investigated. 120 female patients with DM2 and obesity of I-III degree (mean age - 58 +/- 6 years) have been included in the study. The patients were divided into two groups: main group (n = 60) and control group (n = 60). For 3 weeks patients of both groups received a low-calorie diet (1600 kcal/day). Patients of the main group received VMC, providing an additional intake of vitamins C and E (100-120% RDA), beta-carotene (40% RDA), nicotinamide (38% RDA), pantothenic acid and biotin (60% RDA), vitamins B12, B2 and folic acid (75-83% RDA), vitamins B1 and B6 (160-300% RDA), zinc (100% RDA) and chromium (400% RDA), and also received magnesium (17.7% RDA) and potassium (9.4% RDA) in the form of asparaginate. Body composition, biochemical parameters and micronutrient status (blood serum level of vitamins C, D, B6, B12, folate, potassium, calcium, magnesium, zinc, phosphorus) were evaluated in all patients before and after the 3-week course of diet therapy. After the low-calorie diet therapy average body weight reduction was 4.2 +/- 0.2 kg in the main group, and 4.4 +/- 0.1 kg in the control group, without statistically significant differences between groups. Statistically significant decrease of total cholesterol, triglycerides, and glucose concentration in blood serum was registered in both groups. It should be noted that in the control group glycemia decreased on 1.2 +/- 0.1 mmol/l, while the main group showed a decrease on 1.8 +/- 0.1 (p < 0.05) to normal values (5.4 +/- 0.1 mmol/l). Initial assessment of vitamin and mineral status revealed that most patients were optimal supplied with vitamins and minerals. After the dietotherapy significant increase of vitamin C, 25-hydroxyvitamin D, vitamin B6, folate, vitamin B12, potassium, magnesium, calcium, zinc and phosphorus concentration in blood serum was observed in patients receiving VMC. While in the control group statistically significant decrease of vitamin C, magnesium, zinc and phosphorus concentration in blood serum after the treatment was revealed. The obtained data shows the necessity of addition of the vitamin-mineral complex to the diet of patients with DM2 and obesity.

For the soluble apoptosis markers study 151 patients with obesity (92 women and 59 men) aged between 18 and 63 years were examined. Diagnosis and degree of obesity was based on the body mass index (38.2 +/- 5.4 kg/m2). Generally food intolerance was identified in 36.4% of obese patients. Four groups of patients were formed: three groups of patients with obesity stage I (15 patients), II (18 patients) and III (22 patients), respectively, and with food intolerance, and a group of obese patients without food intolerance (control group, n = 31). Obese patients with food intolerance received standard version of hypocaloric diet with the exception of specific food allergens. Duration of observation was 39-43 days. Such soluble apoptosis markers as sFas-L, Caspase-9, Caspase-8 and sCD153 were significantly higher in stage III obesity patients compared obese patients without food allergy (0.120 +/- 0.030 vs 0.035 +/- 0.010; 13.2 +/- 3.2 vs 5.9 +/- 0.4; 1.4 +/- 0.18 vs 0.6 +/- 0.24; 0.123 +/- 0.010 vs 0.025 +/- 0.002 ng/ml respectively). Positive dynamic of sFas-L, Caspase-9 and Caspase-8 (decrease to 0.052 +/- 0.030; 7.7 +/- 2.2 and 0.4 +/- 0.18 ng/ml respectively) in patients with obesity stage III and intactness sCD153 during diet therapy course were revealed. Significant differences for only Caspase-9 in patients with obesity stage II were obtained. The data obtained are considered as normalization of apoptosis due to nutritional correction of immunological disorders. Study of sFas-L, Caspase-9 and Caspase-8 allows to predict the course of disease, as immunological research for early detection of food allergy makes possible to implement the principles of personalized diet therapy.

AIM: To study the effect of adipokines on the metabolism of key nutrients in patients with obesity. SUBJECTS AND METHODS: Ninety patients aged 18 to 66 years old who were treated at the Department of Preventive and Rehabilitative Nutrition, Research Institute of Nutrition, Russian Academy of Medical Sciences, were examined. Carbohydrate and lipid metabolisms were assessed by turbidimetry and spectrophotometry. The levels of adipokines, insulin, and oxidized low-density lipoproteins (LDL) were measured by ELISA. Insulin resistance was assessed with HOMA-IR in all the patients. RESULTS: It was found that there were discoordinated changes in the content of adipokines. The patients with Grade 1 obesity, as compared to the control group, had a statistically significant decrease in the serum concentrations of adiponectin (5.94 +/- 0.90 and 15.34 +/- 0.45 microg/ml; p < 0.05) and ghrelin (215.50 +/- 104.50 and 540.67 +/- 0.76 pg/ml; (p < 0.05) and resistin levels above the normal values (7.34 +/- 1.24 and 5.12 +/- 0.22 ng/ml; p < 0.05; respectively). There was an inverse correlation between the content of adiponectin and ghrelin, and body mass index in obese patients (r1 = -0.25, r2 = -0.15; p < 0.05). There was evidence that there was also an inverse correlation between the levels of adiponectin, triglycerides, LDL, particularly oxidized LDL (p < 0.05). Adipokine-induced insulin resistance appeared as increases in the concentrations of glucose, insulin, and HOMA-IR, as compared to those in the control group. CONCLUSION: A comprehensive approach to evaluating metabolic disorders and adipokine synthesis in obese patients makes it possible to optimize the diagnosis of type 2 diabetes mellitus and cardiovascular diseases and to personalize diet therapy.

The aim of the study was to perform isomeric analysis of hydroxyeicosatetraenoic acid (HETE) in blood samples from obese patients with non-alcoholic (NASH) and alcoholic (ASH) steatohepatitis. Sixty nine obese patients with liver steatosis according to abdominal US data and chronic ALT elevation were assign into two groups aecoriing to the evaluation of alcohol consumption by GAGE and AUDIT questionnaires: NASH - 39 patients and ASH - 30 patients. The identification and quantification of 5(S)-hydroxyeicosatetraenoic acid (5-HETE), 15-HETE and also non-enzymatic oxidation product 11-HETE in blood plasma were carried out by HPLC-MS-TOF with using 2-hydroxyoctanoic acid as internal standard. The position of hydroxyl group in HETE was elucidated by HPLC-MS/MS. The MS/MS transitions were for 15-HETE m/z 319 ---> m/z 219; for 11-HETE m/z 319 --> m/z 167; for5-HETE m/z 319 --> m/z 115. Patients' body composition was evaluated by bioelectrical impedance, resting energy expenditures (REE) were assessed by indirect calorimetry and nutrition pattern was examined by foodfrequency questionnaire. Mean age, BMI and ALT serum level were similar in patients from ASH and NASH groups. Blood plasma 8+12-HETE concentration was also similar in both groups of patients, but concentration of 15-HETE (21,6±20,2 vs 11,9±13,7µg/ml, p =0,02) and 11-HETE (20,8±21,3 vs 11,2+12,9 ug/ml, p =0,03) was significantly higher in NASH patients. ASHpatients demonstrated higher lean body mass (68,1±10,6 vs 57,9±9,8 kg, p<0,001) and muscle mass (39,3±6,1 vs 33,2±6,8 kg, p<0,04) and higher rate of protein oxidation (98,5±3 1 vs 76,2±21,1 g/day, p= 0,02) recalculated from REE. There were no differences found in blood lipids content as well as in consumption of total dietary fat, however, there was a trend to difference in saturated/unsaturated fatty acids ratio between groups (2,3±0,2.in NASH and 1,4±0,3 in ASH patients). In conclusion, the rate of production of eicosatetraenoic acid metabolites by lipoxygenase pathway is different in NASH and ASH overweight patients. It means that possibly different mechanisms are responsible for formation of potentially toxic fatty acids metabolites in these two types of patients. It seems likely that differences in fatty acids consumption pattern are related to this metabolic pathway.

Diet modification is widely used for the treatment of non.alcoholic steatohepatitis (NASH). Caloric restriction was shown to be effective in normalizing bldod lipid profile, increasing insulin sensitivity and subsequent normalization of aminotrasferases blood level. The aim of the study was to compare low-calorie diet (LCD) with isocaloric diet (ICD) in patients w,ith NASH. 174 NASH patients [86 females (39,43±1,53 years old) and 88 males (41,7±2,0), BMI 36,8±0,8 kg/m2] were randomly assigned (as 1:2) for LCD (1600-1700 kcal/day) or ICD (2500-2700 kcal/day) calculated according to patients'sex, age, resting energy expenditures and daily physical activity. Caloric restriction was achieved by decreasing consumption of carbohydrates and fat in LCD, whereas for ICD the caloric consumption was established according to the recommended daily values for proteins, fat and carbohydrates for ideal BMI for every patient. Blood chemistry and body composition were assessed at baseline and after 1 mo of prescribed diets. Compliance for the diet was also evaluated using previously validated questionnaire. After 1 mo of dietetic interventions total body mass and lean mass significantly decreased in both groups, but in LCD group it was significantly more prominent decrease in compare to ICD group (9,3±1,8 vs 6,2±1,7 kg and 6,6±0,4 vs 1,4±0,6 kg, p<0,05), whereas fat mass decreased better in ICD group (4,8±0,7 vs 2, 7±0,8kg, p<0,05). Mean ALT level was decreased in ICD group (77,5±41,7 vs 98,8±45,7, p<0,01), but not in LCD group (81,2±50,6 vs 77,2±31,8, p=NS) whereas blood cholesterol, triglycerides, high density lipoprotein woere significantly decreased in both groups. Moreover during the diet intervention in 72% of patients from LCD group ALT increased. Compliance index was much higher in ICD group, than in LCD group (85% vs 54%). Thus, one month of lCD leads to decrease in ALT activity in majority of NASH patients, higher loss of fat mass, lower loss of lean mass and associated with better compliance in compare to LCD.

The age-dependent nutritional status and resting metabolism in overweight and obese children have been examined. The study included 625 children of 2.5-17 years old. Patients were divided into three groups: 1st--2.5-7 years old (n = 49), 2nd--8-12 years old (n = 204), 3rd--13-17 years old (n = 372). The diagnosis of overweight and obesity was based on CDC criteria: children with 85-94 BMI percentile according to age and gender had overweight, BMI 295 percentile--obesity. Anthropometry, bioelectric impedance analysis and indirect respiratory calorimetry were performed; lipid and carbohydrate parameters were measured. The fat mass percentages in children of studed groups were 41.3 ± 1.9, 39.8 ± 0.7 and 42.3 ± 0.4%, the mean percent of fat mass excess--163.6 ± 26.2, 113.7 ± 8.3 and 134.9 ± 8.2% respectively, p > 0.05. Prevalence of dyslipidemia in children increased with age: lipid metabolism disorders were revealed in 28.6, 49.0 u 53.2% children of the 1st, 2nd and 3rd groups respectively. The mean HDL level in the 1st and 2nd groups was significantly higher, and triglycerides--lower than in the 3rd group. The correlation of HDL level and breastfeeding duration (r1 = 0.94, p < 0.05) was found in the 1st group of children. Increased insulin level was revealed in 38.8% children in the 1st group (mean 12.8 ± 1.4 µIU/ml), 62.2% children in the 2nd group (21.1 ± 0.7 µIU/ml) and 64.8% children in the 3rd group (25.1 ± 0.9 µIU/ml); increased HOMA--in 36.7% (4.32 ± 0.6), 62.2% (4.65 ± 0.17) and 59.1% (5.56 ± 0.21) respectively. The negative correlation of insulin and HOMA level with breastfeeding duration (r1 = -0.38 and -0.37, respectively, p < 0.05) was found in the 1st group of children. Prevalence of hyperuricemia increased from 13% in the 1st group to 21.1% in the 2nd and 44.1% in the 3rd group. Prevalence and degree of resting metabolism changes increased with age and had tendency to the shift of proportion of energy-intensive substrates (fats and carbohydrates) to deceleration of carbohydrate oxidation (in 32, 50, 55.1% of children) and compensatory fat oxidation acceleration (8, 28.4 and 34.7% respectively). Mean fat oxidation rate levels significantly differed between groups and increased with age (48.38 ± 7.14, 54.29 ± 3.06 and 78.43 ± 2.89 g/day in children of the 1st, 2nd and 3rd groups respectively, p < 0.001). The mean level of carbohydrate oxidation rate in the 3rd group of children was lower than normal value (p < 0.01). Resting energy expenditure was lower in the 2nd and 3rd groups of children.

Nanostructured silica (SiO2) "Aerosil" with the size of the primary nanoparticles (NPs) of 5-30 nm, in the form of ultrasound treated water suspension was administered to rats of 80 ± 4 g initial body weight for the first 30 days by intragastric gavage and then for 62 days with diets consumed in doses of 0.1; 1.0; 10 and 100 mg/kg body weight per day. The control group received vehicle of nanomaterial (NM)--deionized water. There were measured in liver of ani- mals the content of total cytochromes P450 and b5 in the microsomal fraction of liver, activity (Vmax) of microsomal monooxygenases with the mixed func- tion of isoforms CYP1A1, 1A2 and 2B1 on their specific substrates, the activity of conjugating liver enzymes glutathione-S-transferase and UDP-glucuronosyl-transferase in microsomal fraction and cytosol, the total and non sedimentable activity of lysosomal hydrolases (ß-glucuronidase, ß-galactozydase, arylsulphatase A, B). The content of PUFA's diene conjugates and TBA-reactive substances in the blood plasma and the activity of antioxidative enzymes (glutathionperoxidase, superoxidedismutase, glutathionreductase, katalase) in erytrocytes were estimated. A set of standard biochemical parameters of blood serum was also examined (total protein, albumin, glucose, creatinine, urea, uric acid, activities of hepatic transaminases). The studies revealed changes of a number of molecu lar markers that could be interpreted as unfavorable. These include isoforms of CYP2B1 activity decrease at a dose HM 1-10 mg/kg of body weight, decrease in the serum content of total protein, albumin and glucose levels in a dose range of 0.1-10 mg/kg. These changes were absent at the maximum dose of NM, which did not allow to clearly establish the dose-response. The remaining studied fig ures resided in the normal range or experienced changes that could not be interpreted as toxic.

The distribution of allele Ser447Ter of lipoprotein lipase gene (LPL) and polymorphic markers E2 and E4 of the apolipoprotein E gene (ApoE) were examined in 100 obese patients at the age of 18-66 years (28 men and 72 women, 40.6 +/- 2.1 years old). The first group included patients with I degree of obesity (n = 26, BMI = 32.5 +/- 0.2), the second group--patients with II degree of obesity (n = 33, BMI = 37.1 +/- 0.2), the third group--patients with grade III obesity (n = 41, BMI = 46.3-1.1) and control group were 18 healthy individuals aged from 22 to 55 years (7 men and 11 women, 36.5 +/- 0.9 years old, BMI = 22.4 +/- 1.8). Maximal frequency of allelic polymorphism epsilon2 has been revealed in patients with I degree of obesity, and allele epsilon4--in patients with III degree of obesity. The most common genotype of ApoE gene was epsilon3/epsilon3 in all three groups of patients with obesity. In a comparative analysis of allelic variants of the Apo E gene occurrence it has been found that the frequency of a polymorphic variant epsilon2/epsilon2 tended to decrease with BMI increasing, whereas a higher rate of detection of genotypes epsilon4/epsilon3, epsilon4/epsilon4 and epsilon2/epsilon4 was found in patients with III degree of obesity. The data obtained suggest that the epsilon4 allele of the Apo E gene is associated with the development of morbid obesity, rather than allele epsilon2. This phenomenon can be explained by the fact that apoE4 isoform has reduced affinity for LDL in comparison with apolipoprotein E3. The maximum concentration of cholesterol, triglycerides and LDL cholesterol has been observed in patients with epsilon2/epsilon4 genotype of ApoE gene, and it was significantly higher than in the control group (p < 0.05). The content of blood lipid fractions in patients with epsilon3/epsilon4 genotype of ApoE gene, in contrast, was the lowest among obese and did not exceed the values of the control group (p > 0.05). These data indicates a small contribution of epsilon4 polymorphism in heterozygous form to the development of dyslipidemia in obesity. The most positive effect of diet treatment was achieved in patients with genotype epsilon3/epsilon3 and epsilon3/epsilon4. An integrated approach to the assessment of lipid metabolism in patients with obesity, including the analysis of polymorphic genetic loci, can optimize and personalize the diet therapy.

At the present time there is a growth in the number of children suffering from chronic viral hepatitis (CVH). The most difficult group consists of patients with mixed-hepatitis, which is associated with a more rapid progression of the disease and the formation of cirrhosis of the liver. The paper presents the data of long-term monitoring of children with chronic hepatitis B+C (CH B+C); it demonstrates the features of a clinical course, the nature of the biochemical, immunologic, and morphologic changes in the natural course of the disease.

AIM: to investigate cytokine profile in patients with type 2 diabetes mellitus (DM) with different degree of obesity. 154 patients with type 2 DM were examined (55.2% women, 44.8% men). All patients received standard antihyperglycemic therapy; mean age was 46.1 +/- 0.82 years, mean duration of disease was 7.2 +/- 1.43 years. The patients were divided into the following groups according to their degree of obesity: grade I obesity (n = 50), grade II obesity (n = 51), grade III obesity (n = 53). 18 healthy volunteers (38.9% men, 61.1% women, mean age 41.2 +/- 3.2 years, BMI - 22.1 +/- 1.8 kg/m2). The patients and healthy volunteers were underwent biochemical analysis, determination of the cytokine profile and estimation of TNF-alpha, IL-1, IL-4, TGF-beta1 by enzyme-linked immunosorbent assay. It has been shown that increase of the body weight excess in patients with type 2 DM and obesity is accompanied with elevation of proinflammatory cytokines (TNF-alpha, IL-1, TGF-beta1) along with the reduction of inflammatory cytokines (IL-4). The TNF-alpha concentration in patients with grade I obesity was 2,8 fold higher than in the comparison group, in patients with grade II and III - 4 and 5,7 fold respectively. A similar trend occurred in TGF-beta1 level: 2 fold increase--when I obesity, 3,3 and 4 fold--respectively for grade II and III. Unidirectional dynamic changes of IL-1 in patients with type 2 diabetes reflects 1,3 fold increase in its level under obesity I grade, 1,7 fold--under II degree and 2,2 fold--under III degree compared to the level in the comparison group. IL-4 level in patients with diabetes and obesity is strikingly contrasted with the index of the comparison group and progressively reduced: 1,7 fold--when grade I obesity, 3,6 fold- with grade II, 7,7 fold--in the grade III. The data obtained indicates that cytokine profile play a critical part in pathogenesis of type 2 DM in association with obesity.

Diabetes mellitus (DM) is a main noninfectious disease, making significant influence on patients quality of life and life time. The medico-social role of diabetes is defined by wide prevalence of a disease in population and high risk of development of incapacitating complications. Therefore, considerable efforts of modern medicine focused on the study of etio-pathogenetic mechanism and the possibility of dietetic correction in this disease. In this review discusses efficacy of dietary therapy in type 2 diabetes, the role of insulin-like growth 1 (IGF-1)/insulin of pathogenesis microvascular complications. The role of inflammation in the development of microvascular complications, in the first place cytokines, act on the insulin signal pathway and affect the intracellular inflammatory kinase cascade was shown. Also, it is shown that adipose tissue inflammation modulates B-cell function and promotes progressive reduction of insulin secretion. When blood glucose levels are elevated, Glucagon-like peptide--1 stimulates insulin secretion, decrease glucagon secretion, improve B-cell function, and slows gastric emptying. It determines the necessity of fulfillment of further researches of cellular and humoral immunity in diabetes mellitus and the development of personal methods in prevention and treatment of this disease.
