Abstract
OBJECTIVES To determine the associations between various glucose and lipid-related indicators with elevated alanine aminotransferase (ALT) in pediatric population. METHODS We analyzed the cross-sectional data of 3,771 Iranian children and adolescents aged 7-18 years using the fifth survey of a national school-based surveillance program. The predictive power of 11 different glucose and lipid-related indicators for predicting elevated ALT was examined using receiver operating characteristic (ROC) curve. RESULTS In the total sample non-HDL-C, non-HDL-C/HDL-C, and TC/HDL-C showed the largest area under the curve (AUC) for elevated ALT detection, with 0.731 (cut-off, 129.5 mg/dL), 0.706, and 0.706, respectively. In girls, non-HDL-C had the highest predictive value (AUC, 0.741, cut-off, 129.5 mg/dL). Among boys, non-HDL-C/HDL-C and TC/HDL-C showed the largest AUC of 0.753 with optimum cut-off values of 2.63 and 3.63, respectively. CONCLUSIONS The findings of this study suggest that non-HDL-C, non-HDL-C/HDL-C, and TC/HDL-C can be predictors of elevated ALT in the pediatric population. These indices can be useful in large population-based studies for predicting children and adolescents at risk of fatty liver.

Unraveling the link between insulin resistance and Non-alcoholic fatty liver disease (or metabolic dysfunction-associated steatotic liver disease): A Narrative Review. J Diabetes Metab Disord 2023; 22:1083-1094. [PMID: 37975107 PMCID: PMC10638269 DOI: 10.1007/s40200-023-01293-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Accepted: 08/24/2023] [Indexed: 11/19/2023]
Abstract
Objective Non-alcoholic fatty liver disease (NAFLD) is rapidly becoming a significant global health concern, representing the leading cause of chronic liver disease and posing a substantial public health challenge. NAFLD is associated with higher insulin resistance (IR) levels, a key pathophysiological mechanism contributing to its development and progression. To counter this growing trend, it is crucial to raise awareness about NAFLD and promote healthy lifestyles to mitigate the impact of this disease. Methods Relevant studies regarding IR and NAFLD published until May 30, 2023, were extracted from Google PubMed, Scopus, and Web Of Science web databases. The following keywords were used: IR, diabetes mellitus, Non-alcoholic fatty liver disease, and metabolic syndrome. Results IR leads to an accumulation of fatty acids within liver cells, resulting from increased glycolysis and decreased apolipoprotein B-100. Furthermore, the manifestations of NAFLD extend beyond liver-related morbidity and mortality, affecting multiple organs and giving rise to various non-communicable disorders such as diabetes mellitus, metabolic syndrome, polycystic ovary syndrome, obstructive sleep apnea, and cardiovascular disease. Although lifestyle modification remains the primary treatment approach for NAFLD, alternative therapies, including pharmacological, herbal, and surgical interventions, may be considered. By implementing early and simple measures, cirrhosis, end-stage liver disease, and hepatocellular carcinoma can be prevented. Conclusions There is a clear association between NAFLD and elevated levels of IR. Several metabolic conditions, such as obesity, type 2 diabetes mellitus, dyslipidemia, and metabolic syndrome, are closely interrelated with NAFLD and IR. Raising awareness about NAFLD and promoting a healthy lifestyle are crucial steps to reverse the impact of this disease.

Exposure to ambient air pollutants, serum miRNA networks, lipid metabolism, and non-alcoholic fatty liver disease in young adults. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2023; 264:115486. [PMID: 37729806 PMCID: PMC10548742 DOI: 10.1016/j.ecoenv.2023.115486] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 08/30/2023] [Accepted: 09/13/2023] [Indexed: 09/22/2023]
Abstract
BACKGROUND AND AIM Ambient air pollution (AAP) exposure has been associated with altered blood lipids and liver fat in young adults. MicroRNAs regulate gene expression and may mediate these relationships. This work investigated associations between AAP exposure, serum microRNA networks, lipid profiles, and non-alcoholic fatty liver disease (NAFLD) risk in young adults. METHODS Participants were 170 young adults (17-22 years) from the Meta-AIR cohort of the Children's Health Study (CHS). Residential AAP exposure (PM2.5, PM10, NO2, 8-hour maximum O3, redox-weighted oxidative capacity [Oxwt]) was spatially interpolated from monitoring stations via inverse-distance-squared weighting. Fasting serum lipids were assayed. Liver fat was imaged by MRI and NAFLD was defined by ≥ 5.5% hepatic fat fraction. Serum microRNAs were measured via NanoString and microRNA networks were constructed by weighted gene correlation network analysis. The first principal component of each network represented its expression profile. Multivariable mixed effects regression models adjusted for sociodemographic, behavioral, and clinical covariates; baseline CHS town code was a random effect. Effects estimates are scaled to one standard deviation of exposure. Mediation analysis explored microRNA profiles as potential mediators of exposure-outcome associations. DIANA-mirPATH identified overrepresented gene pathways targeted by miRNA networks. RESULTS Prior-month Oxwt was associated with NAFLD (OR=3.45; p = 0.003) and inversely associated with microRNA Network A (β = -0.016; p = 0.026). Prior-year NO2 was associated with non-HDL-cholesterol (β = 7.13; p = 0.01) and inversely associated with miRNA Network A (β = -0.019; p = 0.022). Network A expression was inversely associated with NAFLD (OR=0.35; p = 0.010) and non-HDL-C (β = -6.94 mg/dL; p = 0.035). Network A members miR-199a/b-3p and miR-130a, which both target fatty acid synthase, mediated 21% of the association between prior-month Oxwt exposure with NAFLD (p = 0.048) and 23.3% of the association between prior-year NO2 exposure and non-HDL-cholesterol (p = 0.026), respectively. CONCLUSIONS Exposure to AAP may contribute to adverse lipid profiles and NAFLD risk among young adults via altered expression of microRNA profiles.

Abstract
BACKGROUND In addition to coronary artery disease, non-high-density lipoprotein(non-HDL-C) provides short and long-term predictive information for many chronic inflammatory diseases such as stroke, hemodialysis, post-renal transplant, non-alcoholic hepatosteatosis, and human immunodeficiency virus. OBJECTIVES This study examined the predictive value of non-HDL-C measured before SARS-CoV-2 for mortality in COVID-19 infection. METHODS This study retrospectively included 1435 patients diagnosed with COVID-19 and treated in the thoracic diseases ward in a single center between January 2020 and June 2022. All patients included in the study had clinical and radiological features and signs of COVID-19 pneumonia. The COVID-19 diagnosis of all patients was confirmed by a polymerase chain reaction studied from an oropharyngeal swab. Statistical significance was set at p < 0.05. RESULTS The study patients, including 1435 subjects, were divided into 712 patients in the non-surviving group and 723 in the surviving group. While there was no difference between the groups regarding gender, there was a statistically significant age difference. The non-surviving group was older. Age, lactate dehydrogenase(LDH), C reactive protein(CRP), triglycerides, D-dimer, and non-HDL-C were independent risk factors for mortality in regression analyses. In correlation analysis, age, CRP, and LDH were positively correlated with non-HDL-C. In the ROC analysis, sensitivity for non-HDL-C was 61.6%, and specificity was 89.2%. CONCLUSION We believe that the non-HDL-C level studied before COVID-19 infection can be used as a prognostic biomarker for the disease.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is increasingly recognized in obese and overweight children. NAFLD is the commonest cause of chronic liver disease in these children. We undertook a study to assess the prevalence of NAFLD and to identify the associated anthropometric and metabolic risk factors. METHODS This cross-sectional study was done with 154 overweight and obese children. The study population was divided into 2 groups based on the presence or absence of NAFLD by screening with ultrasonography and/or alanine transaminase levels. Anthropometric (body mass index [BMI], waist circumference) and biochemical parameters (triglyceride, high density lipoprotein, low density lipoprotein, very low density lipoprotein, total cholesterol, insulin, homeostasis model assessment of insulin resistance [HOMA-IR], alanine transaminase, aspartate transaminase) were compared between these two groups. RESULTS NAFLD was diagnosed based on abnormal screening in 79 (51.3%) overweight and obese children. No age or gender difference was noted between the 2 groups. There were no significant differences in BMI, systolic blood pressure, diastolic blood pressure, and waist circumference between patients with and without NAFLD. Low-density lipoprotein (LDL) cholesterol levels were found significantly higher in the NAFLD group. There was no significant difference in lipid profile apart from LDL cholesterol, aspartate transaminase, and HOMA-IR between the 2 groups. CONCLUSION NAFLD is common in overweight and obese southern Indian children. High LDL cholesterol level is a risk factor for NAFLD in these children. Screening of this high-risk group for early diagnosis of NAFLD is essential to prevent and monitor further progression of the disease.

Abstract
The prevalence of non-alcoholic fatty liver disease (NAFLD), ranging from simple steatosis to inflammatory steatohepatitis (NASH) and cirrhosis, continues to rise, making it one of the major chronic liver diseases and indications for liver transplantation worldwide. The pathological processes underlying NAFLD not only affect the liver but are also likely to have systemic effects. In fact, growing evidence indicates that patients with NAFLD are at increased risk for developing atherosclerosis. Indeed, cardiovascular complications are the leading cause of mortality in NAFLD patients. Here, we aim to address common pathophysiological molecular pathways involved in chronic fatty liver disease and atherosclerosis. In particular, we focus on the role of oxidized lipids and the formation of oxidation-specific epitopes, which are important targets of host immunity. Acting as metabolic danger signals, they drive pro-inflammatory processes and thus contribute to disease progression. Finally, we summarize encouraging studies indicating that oxidized lipids are promising immunological targets to improve intervention strategies for NAFLD and potentially limit the risk of developing atherosclerosis.

Abstract
The perturbation in plasma free amino acid metabolome has been observed previously in diabetes mellitus, and is associated with insulin resistance as well as the onset of cardiovascular disease in this population. In this study, we investigated, for the first time, changes in the amino acid profile in a group of people with and without type 2 diabetes (T2D) with normal BMI, from Jordan, who were only managed on metformin. Twenty one amino acids were evaluated in plasma samples from 124 people with T2D and 67 healthy controls, matched for age, gender and BMI, using amino acids analyser. Total amino acids, essential amino acids, non-essential amino acids and semi-essential amino acids were similar in T2D compared to healthy controls. Plasma concentrations of four essential amino acids were increased in the presence of T2D (Leucine, p < 0.01, Lysine, p < 0.001, Phenylalanine, p < 0.01, Tryptophan, p < 0.05). On the other hand, in relation to non-essential amino acids, Alanine and Serine were reduced in T2D (p < 0.01, p < 0.001, respectively), whereas Aspartate and Glutamate were increased in T2D compared to healthy controls (p < 0.001, p < 0.01, respectively). A semi-essential amino acid, Cystine, was also increased in T2D compared to healthy controls (p < 0.01). Citrulline, a metabolic indicator amino acid, demonstrated lower plasma concentration in T2D compared to healthy controls (p < 0.01). These amino acids were also correlated with fasting blood glucose and HbA1c (p < 0.05). Glutamate, glycine and arginine were correlated with the duration of metformin treatment (p < 0.05). No amino acid was correlated with lipid profiles. Disturbances in the metabolism of these amino acids are closely implicated in the pathogenesis of T2D and associated cardiovascular disease. Therefore, these perturbed amino acids could be explored as therapeutic targets to improve T2D management and prevent associated cardiovascular complications.

Abstract
Background Childhood obesity increases the risk of non-alcoholic fatty liver disease marked by elevated alanine aminotransferase (ALT). This study investigated the prevalence of increased ALT in children and adolescents with obesity, and its associations with sex, age, degree of obesity, and metabolic parameters. Methods Individuals between 5 and 17.99 years of age enrolled in the Swedish Childhood Obesity Treatment Register (BORIS) before March 2020 were included. Mildly increased ALT was defined by ALT 27–51 U/L (males) and 23–43 U/L (females), while markedly increased ALT by levels above. Multiple logistic regression models were used for statistical analysis. Results Among 11,776 individuals (age 11.0 ± 3.3 years, 53.5% males), the prevalence of mildly and markedly increased ALT were 37.9 and 10.6%, respectively. A sex-age interaction was found, where increasing age strengthened the odds of markedly increased ALT in males (OR, 99% CI: 1.34, 1.29–1.4 for each year) while the corresponding pattern in females with was minuscule (1.09, 1.02–1.10). Compared to class I obesity, class II and III obesity had greater odds ratios for mildly increased ALT (class II obesity OR, 99% CI: 1.51, 1.35–1.70; class III obesity OR, 99% CI: 2.17, 1.66–2.61) and for markedly increased ALT (class II obesity OR, 99% CI: 1.82, 1.51–2.20; class III obesity OR, 99% CI 3.38, 2.71–4.23). Dyslipidemia was associated with both mildly and markedly increased ALT, all p < 0.001. Prevalence of impaired fasting glucose was 19.1% in normal ALT group, 20.4% in mildly increased ALT group, and 29.0% in markedly increased ALT group. Conclusions The risk of markedly increased ALT increased exponentially with age among boys, but not among girls. Higher degree of obesity was observed in individuals with mildly and markedly increased ALT. Further, metabolic derangements were more prevalent among individuals with mildly and markedly increased ALT.

Abstract
The use of translationally relevant animal models is essential, also within the field of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). Compared to frequently used mouse and rat models, the hamster may provide a higher degree of physiological similarity to humans in terms of lipid profile and lipoprotein metabolism. However, the effects in hamsters after long-term exposure to a NASH diet are not known. Male Syrian hamsters were fed either a high-fat, high-fructose, high-cholesterol diet (NASH diet) or control diets for up to 12 months. Plasma parameters were assessed at two weeks, one, four, eight and 12 months and liver histopathology and biochemistry was characterized after four, eight and 12 months on the experimental diets. After two weeks, hamsters on NASH diet had developed marked dyslipidemia, which persisted for the remainder of the study. Hepatic steatosis was present in NASH-fed hamsters after four months, and hepatic stellate cell activation and fibrosis was observed within four to eight months, respectively, in agreement with progression towards NASH. In summary, we demonstrate that hamsters rapidly develop dyslipidemia when fed a high-fat, high-fructose, high-cholesterol diet. Moreover, within four to eight months, the NASH-diet induced hepatic changes with resemblance to human NAFLD.

Ozsu E, Yazıcıoğlu B. Obese boys with low concentrations of high-density lipoprotein cholesterol are at greater risk of hepatosteatosis. Hormones (Athens) 2019; 18:477-484. [PMID: 31754954 DOI: 10.1007/s42000-019-00152-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2019] [Accepted: 10/24/2019] [Indexed: 12/17/2022]
Abstract
PURPOSE Non-alcoholic fatty liver disease (NAFLD) and associated morbidities have become a major public health problem, with a global three-fold increase in incidence among obese children over the last three decades. Although the gold standard for diagnosis of NAFLD is liver biopsy, it is not widely used in children. Imaging techniques, including magnetic resonance imaging (MRI) and ultrasound (US), can provide information on liver fat deposition, however, with variable sensitivity. A number of other predictors are therefore being investigated for pediatric screening and diagnostic purposes. The aim of this study was to assess easily measured parameters to prompt further investigation into NAFLD in obese children. METHODS Obese children/adolescents with a body mass index (BMI) percentile > 95 were enrolled in the study (n = 353). After a 12-hour fast, venous glucose, insulin, cholesterol, triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and uric acid were measured and a full blood count was performed in all subjects. TG/LDL ratio, AST/platelet ratio index (APRI score), and homeostatic model of assessment for insulin resistance (HOMA-IR) were calculated. All patients underwent an abdominal US examination to assess hepatosteatosis. RESULTS Of 353 patients, median age 12.5 (range, 6-17.9) years, 210 patients (59%) had US-proven hepatosteatosis. Female gender reduced the risk of steatosis 2.08-fold (p = 0.005), a one-unit increase in HDL reduced the risk of steatosis 1.02-fold (p = 0.042), and a one-unit increase in BMI led to a 1.11-fold (p = 0.002) increase in the risk of steatosis. CONCLUSION Gender, BMI, and HDL were found to be predictors of steatosis. Male patients with low HDL and high BMI are at greater risk of steatosis and should be carefully examined for the presence of NAFLD.

Abstract
There is evidence that infection by H. pylori can have a critical proportion in the development of hepatocyte injury and both noncancerous and malignant liver conditions including non-alcoholic fatty liver disease (NAFLD). This is attributed to several mechanisms, the most important one being the toxic products of the bacterium H. pylori and oxidative injury for hepatocytes which promotes hepatic injury. The present research was aimed at determining the association between H. pylori infection and the prevalence of NAFLD in Birjand, Iran. Two groups were included in this cross-sectional study at the outpatient university clinic. One group had NAFLD (65 patients) and the other group was healthy controls without NAFLD (65 subjects). The diagnosis of NAFLD was performed using abdominal ultrasound examination and the absence of taking steatogenic medications or alcohol. Serum anti-H. pylori IgG and fecal H. pylori antigen were tested for diagnosing of H. pylori infection using ELISA method. H. pylori infection diagnosis was made if both tests were positive. None of the subjects in either group had symptoms related to the digestive system including dyspepsia, GERD (gastroesophageal reflux disease), or epigastric pain suspicious of peptic ulcer disease. There were 37 patients (28.5%) in both NAFLD (22 cases, 33.8%) and control (15 cases, 23.1%) groups whose H. pylori tests (both IgG and fecal antigen) were positive. Statistically, no significant difference was observed between the two studied groups regarding H. pylori infection frequency (p = 0.37). Asymptomatic H. pylori infection rate was not significantly different between NAFLD patients and control subjects in Birjand, Iran.

Total cholesterol to high-density lipoprotein cholesterol ratio is a significant predictor of nonalcoholic fatty liver: Jinchang cohort study. Lipids Health Dis 2019; 18:47. [PMID: 30744645 PMCID: PMC6371543 DOI: 10.1186/s12944-019-0984-9] [Citation(s) in RCA: 35] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2018] [Accepted: 01/23/2019] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Some studies found out that TC/HDL-C ratio is a predictor of Cardiovascular disease (CVD) and Nonalcoholic fatty liver (NAFLD) is related to CVD. And some researches have already studied that Apolipoprotein B to Apolipoprotein A1 ratio (ApoB/ApoA1) and Triglyceride to High-density lipoprotein cholesterol ratio (TG/HDL-C) were both related with CVD and NAFLD, but few studied the association between TC/HDL-C ratio and NAFLD. So, we suspected the ratio was also related to NAFLD. The research aims to study the predictive value of TC/HDL-C to NAFLD and to help the early detection of NAFLD. METHODS Based on the Jinchang Cohort, the study contained 32,121 participants. We assessed the incidence of NAFLD by the quartiles of TC, HDL-C and TC/HDL-C. Then, the does-response relationship between these indicators and the risk of NAFLD was obtained. Finally, the receiver operator characteristic curve (ROC) was applied to decide the predictive value of TC/HDL-C. RESULTS Among the study participants, the cumulative incidence of NAFLD was 6.30% and the rate of dyslipidemia was 40.37%. The biochemical indicators of NAFLD had a difference with general population. The incidence of NAFLD raised with the quartiles of TC, TG and LDL-C raising, while decreased with the HDL-C' quartiles raising. After controlling confounding factors, TC and TC/HD-C had a positive relationship with NAFLD, while HDL-C had the opposite. Finally, the ROC analysis showed the area under the curve (AUC) of TC/HDL-C (0.645) was greater than TC (0.554), HDL-C (0.627) and Apolipoprotein B to Apolipoprotein A1 (ApoB/ApoA1) (0.613). CONCLUSIONS The TC/HDL-C ratio has significant predictive value to NAFLD.

Abstract
Background The aim of this study was to identify DNA methylation sites in peripheral blood leukocytes from patients with histologically confirmed nonalcoholic fatty liver disease (NAFLD) that included simple hepatic steatosis and nonalcoholic steatohepatitis (NASH). Material/Methods DNA was isolated from peripheral blood leukocytes from patients with histologically diagnosed NAFLD (n=35), including simple hepatic steatosis (n=18) and NASH (n=17). Healthy controls included individuals without liver disease (n=30). DNA was hybridized, and DNA methylation was interrogated in an epigenome-wide association study (EWAS). DNA methylation levels (β-values) were correlated with serum lipid profiles, liver enzymes, and liver histology. Results Circulating blood leukocytes from 35 patients with NAFLD (simple steatosis and NASH) contained 65 CpG sites, which represented 60 genes that were differentially methylated when compared with healthy controls. In the simple hepatic steatosis group (n=18), 42 methylated CpG sites were found to be associated with increased levels of serum alanine aminotransferase (ALT), and 32 methylated CpG sites were associated with increased serum lipid profiles. In the NASH group (n=17), when compared with the simple hepatic steatosis group, methylated CpG sites showed significant correlations with the presence of lobular inflammation compared with hepatic steatosis and fibrosis. Six differentially methylated CpG sites were identified in the ACSL4, CRLS1, CTP1A, SIGIRR, SSBP1 and ZNF622 genes, which were associated with histologically confirmed simple hepatic steatosis and NASH. Conclusions The study identified some key methylated CpG sites from peripheral blood leukocytes, which might be used as serum biomarkers to stratify NAFLD patients into simple hepatic steatosis and NASH.

Abstract
BACKGROUND With the increasing prevalence of childhood obesity, nonalcoholic fatty liver disease (NAFLD) has emerged as the most common cause of pediatric chronic liver disorder. Factors underlying the pathophysiology of NAFLD remain poorly defined. OBJECTIVE This study aimed to describe the metabolic characteristics of children with NAFLD differing in race/ethnicity and to test associations between dyslipidemia and NAFLD. METHODS A retrospective chart review was conducted at a tertiary referral university hospital among 309 children with a diagnosis of NAFLD. RESULTS Participants (mean age 12.5 ± 3.4 years) were 64% male, 63% white, 23% Hispanic, and 14% black. Hispanic children were diagnosed with NAFLD at a significantly younger age (10.6 ± 3.1 years, P < .0001) and lower body mass index (31.5 ± 6.8 kg/m2, P < .0001) than their white and black counterparts. For the entire cohort, prevalence of systolic hypertension was 41%, diabetes 14%, elevated cholesterol 42%, elevated non-high-density lipoprotein cholesterol (non-HDL-C) 58%, elevated low-density lipoprotein cholesterol 36%, elevated triglycerides (TG) 88%, and low high-density lipoprotein cholesterol 77%. Whites had elevated non-HDL-C, low-density lipoprotein cholesterol, and TG compared to blacks or Hispanics. Serum TG and non-HDL-C were significantly correlated to alanine aminotransferase (r = 0.18, P = .01; r = 0.16, P = .02), respectively, and persisted after adjusting for age and body mass index. CONCLUSION Cardiometabolic derangements, especially dyslipidemia, are highly prevalent in children with NAFLD and differ based on race/ethnicity. Serum TG and non-HDL-C may play an important role in the pathophysiology of pediatric NAFLD.

Abstract
Background and Aims The increase in overweight and obese children may be linked to increased rates of liver damage and dyslipidaemia. This study aimed to explore the associations of liver biomarkers with overweight/obesity and dyslipidaemia in Mexican children. Methods The study was a population-based cross-sectional nutritional survey carried out in the State of Nuevo León, Mexico. The study included a 414 subjects aged between 2 and 10 years old (47.8% girls) who took part in the State Survey of Nutrition and Health–Nuevo León 2011/2012. Associations between alanine aminotransferase (ALT) and aspartate aminotransferase (AST), ALT/AST ratio, and major components of serum lipid profile were assessed. Results Children with high ALT (defined as ≥P75) showed higher prevalence of dyslipidaemia than their counterparts, with high prevalence of high TChol (P = 0.053), non-HDL-chol, TG, and low HDL-chol. Children with an AST/ALT ≥T3 ratio were 0.43-times (95% CI: 0.25–0.74) and 0.27-times (95% CI: 0.17–0.44) low likely to be overweight/obese and to have dyslipidaemia than those with an AST/ALT <T1 ratio, respectively. The risk of high TChol, LDL-chol, non-HDL-chol and TG, and low HDL-chol levels also decreased in AST/ALT ratio groups. Conclusions Our results pose the need for further investigation on whether AST/ALT may be useful as screening test in the assessment of children with cardiometabolic risk.

Abstract
OBJECTIVE Cilostazol, a phosphodiesterase 3, has been widely used in patients with arterial disease and is known to have additional beneficial effects on dyslipidemia. However, the effect of cilostazol on hepatic steatosis has not been fully elucidated. We investigated the effect of cilostazol on hepatic ABCA1 expression and hepatic steatosis in diet-induced obesity mice model. METHODS Hepatic ABCA1 expression and lipid accumulation were analyzed in HepG2 cell lines treated with cilostazol. Male C57BL/6 mice were randomly divided into three groups: (1) fed normal chow diet with vehicle; (2) fed high-fat diet (HFD) with vehicle; (3) fed HFD with cilostazol. Cilostazol (30 mg/kg) was orally administered once daily for 9 weeks. RESULTS Cilostazol significantly enhanced ABCA1 expression and restored ABCA1 expression reduced by palmitate in HepG2 cells. Cilostazol treatment ameliorated lipid accumulation induced by palmitate, and this effect was diminished when ABCA1 or LRP1 was silenced by small interference RNA. After silencing of LRP1, ABCA1 expression was decreased in HepG2 cells. Cilostazol significantly enhanced hepatic ABCA1 expression and decreased hepatic fat in HFD-fed mice. Hepatic expression of cleaved caspase-3 and PARP1 was also decreased in HFD-fed mice treated with cilostazol. CONCLUSIONS Cilostazol ameliorated hepatic steatosis and increased ABCA1 expression in the hepatocytes. Enhancing ABCA1 expression with cilostazol represents a potential therapeutic avenue for treatment of hepatic steatosis.

Abstract
Background. Noninvasive tools to diagnose nonalcoholic fatty liver disease (NAFLD), including transient elastography (TE) and enhanced liver fibrosis panel (ELF), have only been evaluated in children with biopsy-proven NAFLD. We evaluated the prevalence of ELF and TE abnormalities in obese children without clinical liver disease and examined the effects of BMI stabilization on ELF and TE in a longitudinal approach. Methods. 39 obese children (17 m, age 12.3 (7.6–17.4) years) who participated in a 12-month lifestyle-intervention program underwent TE and ELF testing at baseline and at completion of the program. Results were compared with data from a nonobese paediatric cohort. Results. TE and ELF at baseline were significantly elevated compared to controls (TE: 5.9 (3.4–8.3) kPa versus 4.45 (2.45–8.85) kPa, P < 0.01; ELF: 9.0 (7.87–9.60) versus 8.6 (7.33–11.52), P = 0.033). All children with elevated TE and ELF results had normal transaminases. After the program, ELF and TE normalized. Reduction of ELF and TE was associated with a decrease in BMI centile. Conclusion. Abnormal TE and ELF results in obese children suggest presence of NAFLD even when transaminases are normal. TE and ELF might be used as monitoring tools for NAFLD. BMI stabilisation normalizes TE and ELF, underlining the impact of lifestyle intervention.

Abstract
Studies have shown that nonalcoholic fatty liver disease (NAFLD) is strongly associated with several metabolic disorders and diseases, such as obesity, type 2 diabetes mellitus, and dyslipidemia. In NAFLD, dyslipidemia is manifested as increased serum triglyceride and low-density lipoprotein cholesterol levels and decreased high-density lipoprotein cholesterol levels, all of which are key risk factors for cardiovascular disease (CVD). CVD is a leading cause of mortality in NAFLD patients. Thus, implementation of an aggressive therapeutic strategy for dyslipidemia with hypolipidemic agents may mitigate the risk for CVD among NAFLD patients. Here, we provide a current review of literature regarding NAFLD, with particular emphasis on dyslipidemia and available treatment options.
