Objectives. Fatty liver disease (FLD) is a major cause of morbidity and mortality worldwide. Dietary cholesterol and alcohol consumption are important risk factors for the progression of FLD, but whether and how alcohol induces more severe FLD with cholesterol ingestion remain unclear. Herein, we mainly used the Lieber-DeCarli diet to establish the FLD mouse model to investigate the synergistic effects of alcohol and cholesterol metabolism on liver damage. The indices of aspartate transaminase (AST), alanine transaminase (ALT), low-density lipoprotein cholesterol (LDL-c), and total cholesterol (TC) levels, inflammation foci, and pathogenesis by hematoxylin and eosin (H&E) and Oil Red O staining revealed that alcohol induces more severe liver damage by influencing cholesterol metabolism, which might be primarily related to the influence of cholesterol absorption, synthesis, and excretion on the liver or small intestine. Moreover, inhibition of absorption of intestinal cholesterol, but not of fat, sucrose, and alcohol, absorption into the body’s metabolism by Ezetimibe, significantly improved FLD in rats fed with the high fat-cholesterol-sucrose and alcohol diet. These results showed that alcohol plays an important role in cholesterol metabolism in FLD.

Background. Nonalcoholic fatty liver disease (NAFLD) in children has been recognized as a major health burden. Serum lipids as well as dietary cholesterol (DC) intake may positively relate to development of NAFLD. The purpose of this study was to investigate anthropometric, biochemical, and dietary intake parameters of obese Greek children with and without NAFLD. Materials and Methods. Eighty-five obese children aged 8–15 (45 boys/40 girls) participated in the study. NAFLD was diagnosed by ultrasonography (US) in all subjects. Liver indexes were measured in all children. A 3-day dietary was recorded for all subjects. Results. 38 out of 85 children (44.7%) were found to have fatty liver. Obese children with increased levels of TC (95% CI: 1.721–3.191), low density lipoprotein (LDL) (95% CI: 1.829–3.058), and increased dietary cholesterol intakes (95% CI: 1.511–2.719) were 2.541, 2.612, and 2.041 times more likely to develop NAFLD compared with the children without NAFLD. Conclusion. The present study showed that TC, LDL, and DC were the strongest risk factors of development of NAFLD. Reducing body weight and dietary cholesterol intakes as well as decreasing serum TC and LDL levels are urgently necessary in order to prevent NAFLD and possible other health implications later in life.

Alcoholic Fatty Liver Disease

Dyslipidemia is currently accepted to be one of the major risk factor for cardiovascular diseases and atherosclerosis. There is no question that the liver plays an important role in the development of atherogenic dyslipidemia and it is simultaneously a target organ, which results in the development of non-alcoholic fatty liver disease (NAFLD). The latter limits the feasibilities of adequate hypolipidemic therapy, thus increasing the cardiovascular risks. There is a need to use hepatoprotectors when atherogenic dyslipidemia in a patient with documented NAFLD is treated with statins and fibrates. The choice of hepatoprotectors depends on the stage of NAFLD. It is expedient to take statins in combination with ursodeoxycholic acid preparations in NAFLD at the stage of steatosis. A combination of statins and a cholesterol absorption inhibitor is more effective in achieving low-density lipoprotein cholesterol goals in patients with hypercholesterolemia. Intestinal microflora-normalizing agents (enteric antiseptics, pre- and probiotics) should be included into a complex of hypolipidemic therapy in patients with NAFLD. Key words: atherogenic dyslipidemia, non-alcoholic fatty liver disease, hypolipidemic therapy.

Abstract Background: Fatty liver disease is a common and major chronic liver disease. It has been implicated that patients have disorders of lipid metabolism and involved in the pathogenesis of fatty liver. Lipid profile plays a very important role in diagnosis of liver diseases hence it was designed to observe relationship between lipid profile and fatty liver disease (FLD) based on ultrasonography (USG).Method and methodology: This Cross-sectional and analytical study was undertaken in the Department of Internal Medicine with collaboration of Department of Radiology and Department of Biochemistry, Universal College of Medical Sciences-Teaching Hospital (UCMS-TH), Bhairahawa, Nepal from March 2019 to February 2020 in total 100 patients diagnosed with FLD by USG.Result: In 100 cases, the male to female ratio was 1.8:1. 56% of the total cases presented with alcoholic fatty liver disease (AFLD) while remaining 44% with non alcoholic fatty liver disease (NAFLD). The spectrum of lipid abnormality was observed with increased total cholesterol (TC), Low Density Lipoprotein (LDL), increased triglycerides (TG) and Very Low Density Lipoprotein (VLDL) in AFLD cases as compared to NAFLD cases. However, it has been observed that TG/HDL and Non-HDL/HDL were higher in NAFLD as compared to AFLD. There was statistical significant difference in HDL (p-value: 0.019) between alcoholic fatty liver disease grade 1 (AFLG1) and non-alcoholic fatty liver disease grade 1 (NAFLG1). Moreover, it was observed statistical significant difference in HDL between AFLG2 and NAFLG2 (p-value: 0.012).Conclusion:Elevated level of TG and decreased HDL has been implicated in the precipitation of the occlusive vascular disease. These parameters in conjunction with Non-HDL/HDL and TG/HDL can be useful in early screening and monitoring of dyslipidemia in the fatty liver patients to prevent cardiovascular diseases.

1. The present study investigated the role of intestinal cholesterol absorption in the regulation of cholesterol metabolism and serum lipoprotein levels in 22 patients with heterozygous familial hypercholesterolaemia on low to normal cholesterol intake. 2. The results showed that the higher the dietary cholesterol absorption, the lower was the overall synthesis of cholesterol. Efficient cholesterol absorption actually reduced the elimination of cholesterol as faecal neutral sterols but not consistently as bile acids. 3. In multifactorial analysis, body mass index and dietary plant sterols were negatively associated with cholesterol absorption, but were unrelated to cholesterol synthesis. 4. Fractional cholesterol absorption was related only to the serum very-low-density triacylglycerol level. It was not associated with the total or low-density lipoprotein cholesterol levels. On the other hand, cholesterol synthesis was significantly associated with the serum concentrations of very-low-density lipoprotein and intermediate-density lipoprotein cholesterol and triacylglycerols, and with those of low-density lipoprotein triacylglycerols. 5. In conclusion, dietary cholesterol absorption is an essential regulator of cholesterol homoeostasis in familial hypercholesterolaemia, even in patients on low cholesterol intake.

Background Epeleuton is 15‐hydroxy eicosapentaenoic acid ethyl ester, a second‐generation synthetic n‐3 fatty acid derivative of eicosapentaenoic acid. The primary objective was to assess the effect of epeleuton on markers of nonalcoholic fatty liver disease (NAFLD) with post hoc analyses of cardiometabolic markers. Methods and Results In a multicenter, randomized, double‐blind, placebo‐controlled trial, 96 adults with nonalcoholic fatty liver disease and body mass index 25 to 40 were randomized in a 1:1:1 ratio to receive epeleuton 2 g/day, epeleuton 1 g/day, or placebo for 16 weeks. A total of 27% of patients had diabetes mellitus. Primary end points of changes in alanine aminotransferase and liver stiffness did not improve at week 16. Secondary and post hoc analyses investigated changes in cardiometabolic markers. Epeleuton 2 g/day significantly decreased triglycerides, very‐low‐density lipoprotein cholesterol, and total cholesterol without increasing low‐density lipoprotein cholesterol. Despite a low mean baseline hemoglobin A1C (HbA 1C ; 6.3±1.3%), epeleuton 2 g/day significantly decreased HbA 1c (−0.4%; P =0.026). Among patients with baseline HbA 1c >6.5%, epeleuton 2 g/day decreased HbA 1c by 1.1% ( P =0.047; n=26). Consistent dose‐dependent reductions were observed for fasting plasma glucose, insulin, and insulin resistance indices. Epeleuton 2 g/day decreased circulating markers of cardiovascular risk and endothelial dysfunction. Epeleuton was well tolerated, with a safety profile not different from placebo. Conclusions While epeleuton did not meet its primary end points on alanine aminotransferase or liver stiffness, it significantly decreased triglycerides, HbA 1C , plasma glucose, and inflammatory markers. These data suggest epeleuton may have potential for cardiovascular risk reduction and nonalcoholic fatty liver disease by simultaneously targeting hypertriglyceridemia, hyperglycemia, and systemic inflammation. Further trials are planned. Registration URL: https://www.clini​caltr​ials.gov ; Unique identifier: NCT02941549.

Objective. To evaluate the effectiveness of comprehensive treatment of patients with postoperative hypothyroidism (PH) and non-alcoholic fatty liver disease (NAFLD). Materials and methods. 40 patients (20 men and 20 women) aged 42±6 years with PH and NAFLD were examined. Patients were divided into two groups: main (n=20) and control (n=20). Prior to the study and after 1 month, the level of total cholesterol (TH), triglycerides (TG), low-density lipoprotein (LDL), alanine aminotransferase (ALT), aspartate aminotransferase (AST) was determined. Patients in both groups were prescribed levothyroxine sodium (125-175 μg a day). Additionally, the 1st group of patients received arginine hydrochloride 42 mg/ml according to the scheme 200 ml a day per 15 days, the next 15 days L-arginine aspartate 200 mg/ml 5 ml a day. And the control group received only levothyroxine sodium. Results. The level of TH in 1st group decreased from 7.1±0.8 to 6.7±0.4 mmol/l, and in 2nd – from 7.2±0.7 to 6.97±0.35 mmol/l. In the 1st group TG decreased from 3.9±0.4 to 3.5±0.3 mmol/l, and in the 2nd – from 3.8±0.5 to 3.7±0.1 mmol/l. LDL in 1st group decreased from 5.9±1.4 to 5.5±1.2 mmol/l, in the 2nd – from 5.8±1.3 to 5.7±1.4 mmol/l. The level of ALT in 1st group decreased from 47.5±1.82 to 40.1±1.73 IU/l, the level of AST – from 41.3±1.52 to 39.8±1.33 IU/l, in no changes in AST and ALT levels were observed in the control group. Conclusions. Comprehensive treatment of patients with PH and NAFLD contributed to the improvement of liver transaminases (reduction of AST, ALT), as well as the normalization of the lipid profile (reduction of TC, TG and LDL).
