Lipid profile indices in young people with GCK-MODY and HNF1A-MODY

Despite the fact that most young patients with hyperglycemia are diagnosed with type 1 (T1DM) and type 2 (T2DM) diabetes, up to 10 % of all cases of the disease are MODY diabetes. The most common types of MODY are GCK-MODY and HNF1A-MODY, therefore the investigation of their clinical and laboratory characteristics, including lipid spectrum indicators is of high clinical significance. The aim of this research work was to study the values of lipid spectrum indicators in patients diagnosed with GCK-MODY and HNF1A-MODY at the age from 18 to 45 years. Lipid profile parameters were investigated in 56 patients aged 18 to 45 years with diagnosed GCK-MODY and HNF1A-MODY by molecular genetic tests, matched by sex, age and body mass index (BMI). No statistically significant differences were found for any of the indicators, however, in patients with HNF1A-MODY, the decrease in HDL-C is determined significantly more often than in GCKMODY. Thus, the group of persons with MODY differs in the level of lipid profile indices depending on the type of MODY.

Influence of Meldonium on Blood Lipid Spectrum and Echocardiography Parameters in Patients with Coronary Heart Disease and or Withoutconcomitant Arterial Hypertension

Introduction. Coronary heart disease (CHD) is one of the main causes of high mortality, disability and reduced quality of life for patients in both Europe and Ukraine. Modern drug therapy of coronary heart disease in combination with arterial hypertension (AH) does not always achieve a satisfactory therapeutic effect. The use of meldonium, which has antioxidant properties, has a positive effect on NO release and has a lipid-lowering effect is promising for patients with AH. The aim of the study. To evaluate the influence of meldonium on lipid metabolism and echocardiography parameters in combination therapy in patients with CHD with stable angina and concomitant AH. Materials and methods. We examined 66 patients with CHD, stable angina pectoris II-III functional class, 40 of them with concomitant AH stage II-III. Patients were divided into 2 groups of 40 and 26 patients, respectively. The first group included patients with CHD and concomitant AH, the second - without pre-existing hypertension. Each of the groups was further divided into 2 subgroups: 1) Patients who were prescribed meldonium at a dose of 750.0 mg/d for 6 months in addition to the basic therapy of the underlying disease (n = 20 for CHD + AH and n = 14 for CHD without hypertension). 2) Patients who continued basic antianginal, disaggregating, hypolipidemic therapy (n = 20 for CHD + AH and n = 12 for CHD without hypertension). Serum levels of triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol were assessed. Indicators of cardiac hemodynamics were determined by echocardiography with assessment of left ventricular end systolic and diastolic volumes and diameters (LVESV, LVEDV, LVESD, LVEDD respectively), the thickness of the interventricular septum and posterior wall of the left ventricle (IVST, LVPWT respectively), pulmonary artery pressure (PAP), LV myocardial mass (LVM) and LV myocardial mass index (LVMI). Results. The use of meldonium for 6 months in patients with CHD and concomitant AH led to a decrease in the concentration of total cholesterol from 5.07 to 4.34 mmol/l and LDL from 2.07 to 1.70 mmol/l. In the group of patients without concomitant hypertension there was a decrease in the concentration of total cholesterol from 4.80 to 3.93 mmol/l, LDL from 1.62 to 1.18 mmol/l and an increase in HDL from 1.18 to 1.37 mmol/l. At 6-month administration of meldonium as a part of combination therapy of patients with CHD with concomitant AH, there is a decrease in LVM from 216.90 g to 181.50 g and LVMI from 109.10 g/m2 up to 91.20 g/m2. In patients without concomitant hypertension, a decrease in LVM from 232,20 g to 183.90 g and LVMI from 121.50 g/m2 to 96.40 g/m2 was observed. Conclusions. Our study showed that meldonium has a positive effect on lipid metabolism and echocardiography. In the group of patients with coronary heart disease and concomitant hypertension on the background of additional use of meldonium for six months, we registered a decrease in TC, LDL and AI. LVPWT, PAP, LVM and LVMI also significantly decreased. In the group of patients with coronary heart disease without concomitant hypertension, we registered a decrease in TC, LDL, AI and an increase in HDL. LVM and LVMI also decreased significantly. Therefore, we consider it appropriate to use meldonium in the complex treatment of patients with coronary heart disease with stable angina and concomitant hypertension.

State of endothelial function, lipid spectrum and features of coronary vessels structure of rats with obesity and insulin resistance under iodine deficiency conditions

The aim of the study was to investigate the changes of endothelin-1 content, blood lipid spectrum parameters, structural features of coronary vessels of rats with insulin resistance and obesity under conditions of adequate iodine supply and iodine deficiency. For the modeling of insulin resistance, rats were kept on high-fructose, obesity – high-calorie, iodine deficiency – iodine deficiency diets. It was found that the development of insulin resistance, obesity and iodine deficiency was accompanied by an increase of endothelin-1 level in 2.41, 2.31 times and at 80.17% in blood serum, relative to the data in intact animals. Insulin resistance and obesity under conditions of limited iodine supply leads to the significant changes in endothelial dysfunction (increase in the level of endothelin-1 in 3.02 and 2.50 times relative to control and at 67.38 and 39.40% – relative to mono iodine deficiency) and dyslipidemia (increase in the atherogenic factor at 48.08% – 4.20 times relative to isolated insulin resistance, obesity and iodine deficiency). Such changes were consistent with the structural violations. In insulin-resistant animals focal unevenness of the outer and inner contours, their uneven thickness, areas of homogeneous enlightenment were observed under the conditions of iodine deficiency in the arterioles and minor arteries of the myocardium. In obese animals under the conditions of iodine deficiency, the vessels of the microcirculatory bed were dilated and overflown with erythrocytes. Endotheliocytes with nuclei elongated along the wall, in some places there is a swelling of the cytoplasm of endotheliocytes. In the wall of minor arteries there are transparent vacuoles, areas of homogeneous eosinophilia, which are caused by the accumulation of glycoproteins. Thus, the development of insulin resistance and obesity in iodine deficiency is accompanied by more significant changes in endothelial function and an increase in proatherogenic fractions in the blood lipid spectrum, as evidenced by changes in the structural organization of myocardial vessels than with proper iodine supply.

Indicators of the Spectrum of Lipids of the Water-Lipid Mantle of the Skin Before and after Pathogenetically Sound Therapy of Patients with Psoriasis

Aim: The aim of the study is to analyze the features of the spectrum of lipids of the water-lipid mantle of the skin before and after pathogenetically sound therapy of patients with psoriasis. Methods: Comparative evaluation of the therapeutic efficacy of monotherapy with the immunobiological drug Humir (adalimumab), as well as its combination with a non-hormonal drug based on natural components Psori Active (cream) in the examined patients with psoriasis vulgaris was performed according to the dynamics of regression of dermatoses clinical manifestations erythema, infiltration, peeling of the skin psoriatic rash, changes in the index PASI, PGA, BSA. Results: The study involved 137 patients. Changes in the level of other components of the lipid spectrum of the water-lipid mantle of the skin, in particular phospholipids, cholesterol and cholesterol esters in patients of the first observation group changed insignificantly compared to their values before treatment. When comparing the normalization of the level of the studied spectrum of lipids of the water-lipid mantle of the skin in patients of the second group with different seasonal types (autumn-winter, spring-summer, off-season) and previously diagnosed with varying severity treatment, no statistically significant differences were found between seasonal types of dermatosis. Conclusion: Analysis of the results of clinical follow-up of the examined patients with psoriasis of the first and second groups after completion of treatment and achieving clinical clinical remission indicates significant benefits of systemic immunobiological therapy in combination with topical therapy with Psori Active.

Biochemical Markers of Free Radical Oxidation and Lipid Exchange in Rats with Obesity, Iodine Defficiency and Obesity in Combination with Iodine Defficiency

The purpose of the study was the content of lipid and protein peroxidation products, lipid spectrum parameters and the level of aminotransferases in obese, iodine deficient and obese rats in combination with iodine deficiency. Materials and methods. The study was performed on 45 white nonlinear rats weighing 120-180 g, which were divided into three experimental groups: obese rats (1st experimental group, n = 15), iodine-deficient animals (2nd experimental group), obese animals in combined with iodine deficiency (3rd experimental group, n = 15). The control group consisted of 15 intact rats. The content of products of lipid peroxidation and oxidative modification of proteins was determined in the blood and liver tissue of rats. Blood lipid spectrum was assessed by serum levels of triacylglycerols, total cholesterol, high-density lipoproteins and low-density lipoproteins, followed by calculation of the atherogenic factor. The activity of aspartate aminotransferase and alanine aminotransferase was determined in the blood. Results and discussion. It was found that in the liver tissue of rats and blood of experimental groups the content of lipid hydroperoxides and active products that react with thiobarbituric acid increases, which indicates the activation of lipoperoxidation processes. A variety of changes in protein peroxidation in both blood serum and liver tissue of animals of experimental groups was revealed. Regarding the lipid spectrum, the most pronounced differences in the indicators in relation to the control were found in obese animals in combination with iodine deficiency. In this group of animals, cholesterol was increased by 65% in reference to control, triacylglycerol content increased by 52%, low-density lipoprotein exceeded control by 60%, and high-density lipoprotein decreased by 61% in reference to control. The highest activity of aspartate aminotransferase was found in the group of animals with iodine deficiency, and alanine aminotransferase – in the group of obese animals. Conclusion. In the blood and liver tissue of rats with obesity, iodine deficiency and obesity in combination with iodine deficiency increases the content of products of free radical oxidation. The content of cholesterol, triacylglycerols, low-density lipoproteins increases in the blood, the content of high-density lipoproteins decreases, the activity of aspartate aminotransferase and alanine aminotransferase increases. The most pronounced differences in the indicators in reference to the control were found in obese animals in combination with iodine deficiency

Dynamics of Pro- and Anti-inflammatory Cytokines in Experimental Animals with Non-alcoholic Fatty Liver Disease Under Conditions of Hypobaric Hypoxia

AIM: The aim of the study was to study the level of pro- and anti-inflammatory cytokines, tumor necrosis factor-alpha (TNF-α), and interleukin 4 (IL-4), on a model of non-alcoholic fatty liver disease (NAFLD) in experimental animals under conditions of low mountains and hypobaric hypoxia. METHODS: The study was carried out on 180 male Wistar rats, which were divided into control and experimental groups. The rats of the control group were on a standard diet. NAFLD was modeled by keeping animals on a diet (Ackermann et al., 2005) rich in fructose and fat in conditions of low mountains and hypobaric hypoxia (in a pressure chamber 6000 m above sea level) for 35 and 70 days. Total cholesterol (TC) and lipid spectrum, pro- and anti-inflammatory cytokines were determined in all groups of animals. RESULTS: The activity of pro- and anti-inflammatory cytokines in the main group during the rise of animals in the pressure chamber increased statistically significantly on the 35th day in comparison with the low-altitude group by more than 2 times, and on the 70th day of staying at the high-altitude did not have convincing differences from the low-altitude group. The cytokine index (TNF-α/IL-4) of animals in conditions of hypobaric hypoxia on a fructose enriched diet increased by more than 1.5 times after 5 weeks, staying at an altitude for 10 weeks led to a decrease of TNF-α/IL-4 in relation to the low-mountain group, in which the opposite picture was observed - a tendency towards an increase in TNF-α/IL-4. IL-4 and TNF-α _levels were statistically significantly correlated with lipid metabolism disorders. CONCLUSION: NAFLD in animals on a special diet enriched with fructose under conditions of hypobaric hypoxia leads to deeper disturbances in the system of pro- and anti-inflammatory cytokines and the lipid spectrum.
