Intensity Training

Background: Despite the positive effects of high-intensity training on weight management and health-related outcomes, it is postulated that high-intensity training may also induce oxidative stress, increasing hepatic damage. Aim: The aim of this study was to compare the effects of low versus high-intensity training on biomarkers related to non-alcoholic fatty liver disease (NAFLD) in adolescents with obesity. Methods: For this study 107 adolescents (15 ± 1 years) with obesity (BMI = 34.7 ± 4.1 kg/m2) were randomized into High-Intensity Training (HIT, n = 31), Low-Intensity Training (LIT, n = 31) or Control Group (CG, n = 45). Adolescents from HIT and LIT received nutritional, psychological and clinical counseling. Blood lipids, Castelli risk index, glucose, insulin and hepatic enzymes were measured at baseline and after 12 weeks. Results: Castelli risk index 1 was reduced in all groups ( p < 0.001) with moderate effect size ( d) for HIT ( d = 0.62) and LIT ( d = 0.66). Castelli risk index 2 also decreased ( p < 0.001 for all groups; HIT d = 0.65; LIT d = 0.79). High-density lipoprotein increased in all groups ( d = 0.25 and d = 0.18 in HIT and LIT), while alanine aminotransferase tended to reduce ( p = 0.062) in HIT ( d = 0.34) and LIT ( d = 0.73) and aspartate aminotransferase decreased ( p = 0.024) in both HIT ( d = 0.24) and LIT ( d = 0.45). There were no changes in glucose, insulin and insulin resistance. Conclusion: Both high and low-intensity training improved biomarkers related to NAFLD. Thus, high-intensity training can be a safe and effective alternative to prevent and treat NAFLD in adolescents with obesity.

Alcoholic Fatty Liver Disease

Nowadays, coronary heart disease and non-alchoholic fatty liver disease are significant problems in Ukraine and world. Functional liver disorders potentiate the development and progression of CHD. The initiation process of atherosclerosis is a chronic systemic inflammation of low intensity. This view on atherosclerosis development has been forming during the past two decades. The aim of the research was to study the features/characteristics of systemic inflammation of low intensity in patients with coronary heart disease in combination with non-alcoholic fatty liver disease. The research involved 135 people with CHD: stable angina, I-II functional class, 0-I heart failure in combination with non-alcoholic fatty liver disease and 30 healthy individuals. We examined patients in terms of blood levels of cytokines -TNFα and IL-10, the content of the acute phase reactant and the coagulation factor, the marker of endothelial dysfunction is the amount of circulating endothelial microparticles (CEM) CD32+ CD40+ and the expression level of IkBα gene NF-kB in mononuclear peripheral blood. We studied the level of expression of the mRNA gene of IkBα in mononuclear cells, which reflects the level of transcriptional activity of NF-kB in patients with stable coronary artery disease and CHD in combination with NAFLD showed a significant increase in the expression of the mRNA gene of IkBα by 88.5% compared to patients with stable stable coronary heart disease. The analysis of the functional state of the endothelium with help of CEM CD32+ CD40+ has shown the presence of endothelial dysfunction in the groups of patients with CHD and CHD in combination with of NAFLD. Comparison of the indicators of systemic inflammation of low intensity and marker of endothelial dysfunction in patients with CHD in combination with NAFLD revealed a significant increase of TNFα, acute phase reactant and coagulation fibrinogen factor and expression of the mRNA IkBα gene in patients with comorbidity, indicating an increase the level of systemic inflammation of low intensity in patients with CHD in combination with NAFLD as compared with the group of patients with CHD.

Objective. To assess the effect of antihypertensive therapy with ramipril and indapamide on the elasticity of the vascular wall of the large arteries in relation to insulin resistance and chronic low-intensity inflammation in patients with hypertension (HTN) and non-alcoholic fatty liver disease (NAFLD). Design and methods. An open prospective controlled study was conducted: 30 patients with HTN stage I–II in combination with NAFLD (Fatty Liver Index (FLI) > 60) at the age of 45–65 years were included. Washout period was scheduled 5–7 days before the baseline examination, followed by the prescription of one of the fixed combinations of ramipril (2,5/5 mg/day) and indapamide (0,625/1,25 mg), depending on the required dosage (Konsilar-D 24 VERTEX AO, Russia) and were given recommendations on lifestyle changes and weight loss. A clinical examination was carried out, indicators of daily blood pressure (BP) monitoring and central aortic pressure (CAP), pulse wave velocity (PWV), lipid and carbohydrate metabolism, chronic low-intensity inflammation and the severity of insulin resistance before and after treatment were analyzed. Results. After 24-week therapy with a fixed combination of ramipril and indapamide at an average dosage of 4,04 ± 1,24 and 1,01 ± 0,31 mg, respectively, 100% of patients with HTN and NAFLD achieved target BP levels. According to 24-hour BP monitoring data, a significant decrease in systolic BP (SBP) and diastolic BP (DBP) was observed, both in the daytime (Δ12 mm Hg, р = 0,0001; Δ5,5 mm Hg, р = 0,0019, respectively), and at night (Δ13,5 mm Hg, р = 0,0006; Δ5,5 mm Hg, р = 0,0054, respectively). In addition, there was a significant decrease in CAP in the daytime (SBPao p = 0,0011, DBPao p = 0,0022) and night hours (SBPao p = 0,0015, DBPao p = 0,00124), and a statistically significant decrease in augmentation index (day p = 0,0460, night p = 0,0182). When evaluating clinical data and bioimpedance measurements, a decrease in waist circumference (p = 0,0000), hip circumference (p = 0,0001), the proportion of subcutaneous (p = 0,0134) and visceral (p = 0,0019) fat was found, which may indicate a decrease in the severity of visceral obesity. Also, during treatment, there is a decrease in the severity of insulin resistance (and the concentration of tumor necrosis factor alpha (TNF-α) (p < 0,0001) and CRP (p = 0,0002) in blood plasma. Finally, fixed combination of ramipril and indapamide led to a significant decrease in vascular stiffness (p = 0,0166) and a decrease in the proportion of patients with PWV paradoxical test (p = 0,0320). Correlation analysis showed that increased stiffness of the large arteries in patients with HTN and NAFLD is closely related to insulin resistance and lipid metabolism. At the same time, after 24-week therapy by a fixed combination of ramipril and indapamide, a decrease in the vascular stiffness in patients with HTN and NAFLD significantly correlated with the TNF-α concentration. Conclusions. A 24-week therapy by the fixed combination of ramipril and indapamide iin patients with HTN and NAFLD is associated with the persistent decrease in BP and CAP, both during the day and at night. There was a decrease in the vascular rigidity in muscular arteries. The treatment and recommendations for changing the lifestyle are associated with the decrease in the severity of abdominal obesity and insulin resistance, as well as the decrease in the severity of low-intensity systemic inflammation in patients with HTN and NAFLD, and a significant correlation was established between a decrease in TNF-α and an increase in the vascular elasticity of muscle and elastic type arteries.

Abstract. Some epidemiological evidence suggests an inverse correlation between non-alcoholic fatty liver disease (NAFLD) frequency and vitamin D levels. Likewise, a beneficial effect of vitamin D on diabetes mellitus (DM) and insulin resistance has been observed, but this is an unsolved issue. Thus, we aimed to investigate the prevalence of hypovitaminosis D in a NAFLD Brazilian population and its association with disease severity and presence of comorbidities. In a cross-sectional study, the clinical, biochemical and histological parameters of 139 NAFLD patients were evaluated according to two different cut-off points of serum 25-hydroxyvitamin D levels (20 ng/mL and 30 ng/mL). The mean age of the population was 56 ± 16 years, most patients were female (83%), 72% had hypertension, 88% dyslipidemia, 46% DM, 98% central obesity, and 82% metabolic syndrome. Serum vitamin D levels were < 30 ng/mL in 78% of the patients, and < 20 ng/mL in 35%. The mean vitamin D level was 24.3 ± 6.8 ng/mL. The comparison between the clinical, biochemical and histological characteristics of the patients according to the levels of vitamin D showed no significant difference. Most patients with NAFLD had hypovitaminosis D, but low vitamin D levels were not related to disease severity and the presence of comorbidities.

Objectives: To evaluate the frequency of non-alcoholic fatty liver disease, the retinol serum levels, lipid profile, and insulin resistance in overweight/obese children. To relate these biochemical variables with the risk of this disease in the population studied. Methods: The study was cross-sectional and prospective, with 46 overweight/obese school children (28 female, 18 male; mean age 8.6 years). The control group consisted of 45 children, paired by age and gender. Hepatic steatosis, evaluated by ultrasound, was classified as normal, mild, moderate, or severe. Also evaluated were serum retinol levels; thiobarbituric acid reactive substances; lipid profile; and fasting glucose and serum insulin levels, used for the calculation of the Homeostasis Model Assessment. Results: Hepatic ultrasound alterations were found in 56.5% and 48,9% of the overweight/obese and control group children, respectively. Presence of obesity was associated with high levels of triglycerides (OR = 4.6; P = 0.002). In the studied children, the risk of steatosis was related to a trend to a higher percentage of retinol inadequacy (OR = 2.8; p = 0.051); there was no association with thiobarbituric acid reactive substances, lipid profile, or insulin resistance. Conclusions: The high frequency of non-alcoholic fatty liver disease in both groups, evaluated by hepatic ultrasound, in low-socioeconomic level children, independent of nutritional condition and without significant association with insulin resistance, emphasizes that especially in developing countries, other risk factors such as micronutrient deficiencies (e.g. vitamin A) are involved.
