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.

Background: Non-alcoholic fatty liver disease (NAFLD) can increase the incidence of cardiovascular disease and hepatocellular carcinoma. Thyroid hormones also play important roles in hepatic lipid metabolism and hepatic insulin resistance. Hypothyroidism is associated with reduced lipolysis and decreased liver uptake of free fatty acids derived from triglycerides. In recent years, the correlation between overt or subclinical hypothyroidism and NAFLD has been discussed. The relationship between NAFLD and thyroid function parameters remains unclear. Aim: We aimed to evaluate the relationship between serum level of Thyroid Stimulating Hormone (TSH) within normal reference range and Non Alcoholic fatty liver Disease (NAFLD). Subjects and Methods: This is a cross sectional case control study on 40 patients with NAFLD and a control group of 20 healthy individuals, who were attendants of Outpatient Clinic of Internal Medicine Department of Tanta University Hospitals and EL-Menshawy General Hospital from February 2018 to the end of January 2019. Results: In the present study, univariate regression analysis showed that serum levels of AST, FT3, FT4 and Anti-TPO were independent risk factors of NAFLD, while in multivariate analysis the only independent risk factor of NAFLD was Anti-TPO serum level. Conclusion: Serum levels of AST, FT3, FT4 and Anti-TPO were independent risk factors of NAFLD in univariate regression analysis, while in multivariate analysis the only independent risk factor of NAFLD was Anti-TPO serum level. Despite the positive correlation between serum TSH level and grade of NAFLD, the study didn’t show serum TSH level as independent risk factor of NAFLD.

Aim. To estimate the blood levels of primary, secondary, tertiary and unconjugated bile acids in patients with non-alcoholic fatty liver disease.Methods. The study included 74 patients with non-alcoholic fatty liver disease (males - 30, females - 44) and 51 healthy individuals (males - 14, females - 37). All patients underwent anthropometry and complete clinical, biochemical and instrumental examination (measuring the subcutaneous fat layer). 64 patients had hepatic steatosis, 10 - steatohepatitis. Serum levels of bile acids (primary: cholic, chenodeoxycholic; secondary: lithocholic, deoxycholic and tertiary: ursodeoxycholic) were measured by gas-liquid chromatography on «Chromos GC-1000» (Russia) scanner.Results. Unconjugated primary, secondary and tertiary bile acids were detected in the blood of healthy individuals and patients with non-alcoholic fatty liver disease. In healthy individuals, there were no gender differences found in the bile acids levels. Patients with non-alcoholic fatty liver disease had higher level of bile acids compared to healthy controls. There was a significant difference in the concentrations of secondary and tertiary bile acids in patients with hepatic steatosis and steatohepatitis.Conclusion. Blood bile acids levels were significantly higher in patients with non-alcoholic fatty liver disease than in healthy individuals. At steatohepatitis, females had higher levels of cholic, chenodeoxycholic and deoxycholic acids and lower levels of lithocholic and ursodeoxycholic acids compared to males. Significant difference in patients with hepatic steatosis and steatohepatitis was revealed only in levels of secondary and tertiary bile acids.

Alcoholic Fatty Liver Disease

The pathogenetic mechanisms involved in the progression of non-alcoholic fatty liver disease (NAFLD) have not been completely elucidated, while the significance of circulating cell-free DNA (cf-DNA) species has been rarely evaluated in NAFLD. Herein, we assessed the serum levels of cf-DNA species in NAFLD patients and investigated their potential associations with patients’ characteristics and severity of liver disease. Forty-nine adult patients with NAFLD of any stage were included in this cohort study. Cf-DNA was isolated from patients’ sera and the levels of several distinct cf-DNA species including total cf-DNA, gene-coding cf-DNA, Alu repeat sequences, mitochondrial DNA copies and 5-methyl-2′-deoxycytidine were determined. Cirrhotic compared to non-cirrhotic patients had significantly lower serum levels of cf-DNA and RNAse P coding DNA as well as higher expression of 5-methyl-2′-deoxycytidine. After adjustment for the significant clinico-epidemiological factors, lower serum levels of cf-DNA or RNAse P were independently associated with the presence of cirrhosis. Serum levels of total and gene-coding DNA are associated with the presence of cirrhosis in NAFLD patients regardless of clinical or epidemiological parameters and may therefore be used as a screening tool for NAFLD progression.

Non-alcoholic fatty liver disease (NAFLD) is highly prevalent worldwide. Oxidative stress is thought to be a major mechanism, and previous epidemiological studies found higher serum levels of antioxidant carotenoids were associated with reduced risk for development and progression of NAFLD. The objective of this analysis is to examine cross-sectional associations between dietary and serum levels of carotenoids in relation to NAFLD among a nationally representative sample of US adults. We used data from the 2003–2014 National Health and Nutrition Examination Survey (NHANES). Dietary carotenoid intake was estimated from a 24-hour recall, while serum carotenoids were measured from 2003 to 2006. The NAFLD status was determined based upon US Fatty Liver Index (FLI) value ≥30. Regression models were used to estimate associations between carotenoids and NAFLD by controlling for covariates and adjusting for survey design variables. Overall, 33% of participants were classified as having NAFLD. Intake of all carotenoids, with the exception of lycopene, was lower among those with NAFLD. This association was significant for the highest quartiles of intake of α-carotene, β-carotene, β-cryptoxanthin, and lutein/zeaxanthin. For serum measures, the highest level of all carotenoids was associated with significantly reduced odds of NAFLD. In conclusion, higher intake and serum levels of most carotenoids were associated with lower odds of having NAFLD. Identification of such modifiable lifestyle factors provide an opportunity to limit or prevent the disease and its progression.

AIM: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in the general population. Overweight is a common conditions in patients with NAFLD, and body composition (BC) assessment is useful to evaluate nutritional status and the efficacy of nutritional strategies. A valid tool for assessing BC is dual-energy X-ray absorptiometry (DXA). Adiponectin has been shown to be relevant to the pathogenesis of NAFLD. The aim of this observational study is to define the relationship between the severity of NAFLD, the central fat mass evaluated by DXA, and the circulating levels of adiponectin.METHODS: The study was carried out in 31 overweight patients. The degree of liver steatosis was evaluated by ultrasound (US) examination. Anthropometric parameters were measured according to standard methods. Fasting glucose and insulin level were used also to calculate insulin resistance (IR), according to the homeostasis model assessment-insulin resistance (HOMA-IR). The enzyme-linked immunosorbent assay technique was performed to dose fasting serum levels of adiponectin.RESULTS: NAFLD progression was significantly associated with increased central fat (p<0.05). Using DXA, we quantified the regional distribution of adipose tissue and found the expected association between central fat and the US severity of NAFLD. Serum levels of adiponectin, were inversely related to NAFLD progression (p<0.05).CONCLUSION: BC evaluated by anthropometry and DXA, may be used as indicator of NAFLD severity in overweight patients. The evaluation of BC in clinical practice, can improve the nutritional strategies and follow-up. In the clinical setting adiponectin can represent a potential marker for the staging of NAFLD.

The available data on the association between micronutrients in the blood and non-alcoholic fatty liver disease (NAFLD) are limited. To investigate the clinical implications of this relationship, we sought to identify the difference in the serum levels of vitamins A and E according to NAFLD status using data from the seventh Korea National Health and Nutrition Examination Survey. In this cross-sectional study of the Korean population, NAFLD and its severity were defined using prediction models. Differences in the prevalence and severity of NAFLD were analyzed according to serum retinol (vitamin A) and alpha (α)-tocopherol (vitamin E) levels. Serum levels of retinol and α-tocopherol were positively correlated with the prevalence of NAFLD. In most prediction models of the NAFLD subjects, serum retinol deficiency was significantly correlated with advanced fibrosis, while serum α-tocopherol levels did not differ between individuals with or without advanced fibrosis. Similar trends were also noted with cholesterol-adjusted levels of α-tocopherol. In summary, while circulating concentrations of retinol and α-tocopherol were positively associated with the presence of NAFLD, advanced liver fibrosis was only correlated with serum retinol levels. Our findings could provide insight into NAFLD patient care at a micronutrient level.

L-carnitine transports fatty acids into the mitochondria for oxidation and also buffers excess acetyl-CoA away from the mitochondria. Thus, L-carnitine may play a key role in maintaining liver function, by its effect on lipid metabolism. The importance of L-carnitine in liver health is supported by the observation that patients with primary carnitine deficiency (PCD) can present with fatty liver disease, which could be due to low levels of intrahepatic and serum levels of L-carnitine. Furthermore, studies suggest that supplementation with L-carnitine may reduce liver fat and the liver enzymes alanine aminotransferase (ALT) and aspartate transaminase (AST) in patients with Non-Alcoholic Fatty Liver Disease (NAFLD). L-carnitine has also been shown to improve insulin sensitivity and elevate pyruvate dehydrogenase (PDH) flux. Studies that show reduced intrahepatic fat and reduced liver enzymes after L-carnitine supplementation suggest that L-carnitine might be a promising supplement to improve or delay the progression of NAFLD.
