Abstract Aims To determine the prevalence of hepatic steatosis in a cohort of previously healthy children and adolescents, with the use of abdominal computer tomography (CT). Methods Retrospective review of the Sickkids trauma database from (year 2004 to 2015). Inclusion criteria: previously healthy children ages 1-17yr having undergone an abdominal CT scan as a part of routine trauma assessment. Exclusion criteria: Involvement of spleen and/or liver in the injury, known metabolic condition, concurrent use of medications that could predispose to hepatic steatosis. Steatosis was defined as a liver spleen attenuation index (L/S AI) of <0.8. Anthropometrics and baseline demographics were collected. Statistical analyses were performed using Graphpad Prism 7. Results A total of 143 children were included in the analyses with a mean (SD) age of 7.12(4.26) years. 88 children were male (7.10(4.24) years old). The mean (SD) weight z score was 0.48 (0.97). Fifteen percent of the 137 children with a weight z-score between -2 to 2 had evidence of hepatic steatosis on imaging (using liver/spleen index <0.8). Twenty seven percent (6/22) of children with weight z-scores less than the 33rd percentile had L/S AI <0.8. An inverse correlation between weight z-scores and L/S AI was found in children >10 years (P<0.016) (Fig 1); however there was no correlation in pre-pubertal children (P<0.374). Conclusions Hepatic steatosis is highly prevalent in this cohort of healthy children in Ontario. Larger population based studies are needed to investigate the prevalence of hepatic steatosis in children across Canada. Funding Agencies None

Introduction: Cardiovascular complications are a leading cause of mortality in nonalcoholic fatty liver disease (NAFLD). Fructose has been reported to be associated with dyslipidemia and increased cardiovascular risk in adults but its impact on adolescents with NAFLD is not well understood. We previously demonstrated that fructose disproportionately increased postprandial hypertriglyceridemia in pediatric NAFLD as compared to healthy children. However, the mechanism remains unclear. Hypothesis: We hypothesized that fructose would contribute to hypertriglyceridemia in pediatric NAFLD by increasing the size of VLDL particles. Methods: We examined the acute response to a single dose of fructose beverage in 50 Hispanic-American obese adolescents with varying degrees of hepatic steatosis. Those with hepatic fat >5% on MRI imaging were designated as presumed NAFLD. Subjects consumed a 12oz drink containing 33g of fructose and plasma samples were collected at baseline and 30, 60, and 90 minutes afterwards. Plasma lipoproteins were measured using NMR (Liposcience, Raleigh, NC). Results: In response to acute fructose load, subjects without NAFLD increased the total number of TG rich lipoprotein particles (p = 0.047). However, this increase was not observed in subjects with NAFLD; instead, they increased the subpopulation of large VLDL particles (p = 0.008) and the mean size of VLDL particles (p = 0.004) (Figure 1). In line with this finding, TG-to-apoB ratio significantly increased in subjects with NAFLD (2.25 ± 0.26 to 2.37 ± 0.25, p = 0.031) but not in non-NAFLD. Conclusions: These findings demonstrate that adolescents with NAFLD have more atherogenic, large VLDL in response to fructose compared to obese adolescents without NAFLD. Dietary fructose restriction may be a critical component in the treatment of NAFLD associated cardiovascular disease and should be tested further.

184 Background: The I148M polymorphism (rs738409) of the patatin-like phospholipase domain-containing 3 (PNPLA3) gene is strongly associated with hepatic triglyceride content (HTGC) and the development of nonalcoholic fatty liver disease (NAFLD) and steatohepatitis (NASH), which are themselves risk factors for hepatocellular cancer (HCC). Serum adiponectin affects insulin resistance and carcinogenesis and has also been associated with HTGC. Whether these risk factors are additive in predisposing to HTGC is unknown. We evaluated the impact of adiponectin and PNPLA3 genotypes on HTGC in a large community cohort. Methods: The Dallas Heart Study (DHS) is a multi-ethnic population based study of Dallas County residents. HTGC was quantified using H-MR spectroscopy. Univariate and multivariable logistic and linear regression models were generated to test the association between HTGC and log adiponectin stratified by PNPLA3 genotype (CC, CG and GG). Models were adjusted for age, gender, race, hypertension, diabetes, HOMA-IR and BMI. Results: There were 2,259 patients who had complete clinical, biochemical, imaging, and genotyping data and were included in this analysis. Median age was 44 and 47% were male. Race distribution was 48% Black, 32% White, and 18% Hispanic. The prevalences of PNPLA3 genotypes were 61% CC (wild type), 32% GC and 7% GG. The median concentration of adiponectin was 6.6 ug/ml. Adiponectin was an independent predictor HTCG across all genotypes after adjusting for covariates (CC b=-0.34, GC b=-0.42, GG b=-0.38, p<0.005 for each). HTGC decreased across gender and race-stratified quartiles of adiponectin for each PNPLA3 genotype, and the qualitative effect was greatest in the I148M homozygotes (table). Conclusions: Adiponectin is independently associated with hepatic steatosis across all three PNPLA3 genotypes. The combination of at-risk PNPLA3 genotypes and hypoadiponectemia is associated with a high risk of hepatic steatosis. Future studies will need to address downstream HCC risk and whether manipulation of adiponectin level may be of clinical benefit. [Table: see text]

In preclinical studies of fructose-induced NAFLD, endotoxin appears to play an important role. We retrospectively examined samples from three pediatric cohorts (1) to investigate whether endotoxemia is associated with the presence of hepatic steatosis; (2) to evaluate postprandial endotoxin levels in response to fructose beverage in an acute 24-hour feeding challenge, and (3) to determine the change of fasting endotoxin amounts in a 4-week randomized controlled trial comparing fructose to glucose beverages in NAFLD. We found that adolescents with hepatic steatosis had elevated endotoxin levels compared to obese controls and that the endotoxin level correlated with insulin resistance and several inflammatory cytokines. In a 24-hour feeding study, endotoxin levels in NAFLD adolescents increased after fructose beverages (consumed with meals) as compared to healthy children. Similarly, endotoxin was significantly increased after adolescents consumed fructose beverages for 2 weeks and remained high although not significantly at 4 weeks. In conclusion, these data provide support for the concept of low level endotoxemia contributing to pediatric NAFLD and the possible role of fructose in this process. Further studies are needed to determine if manipulation of the microbiome or other methods of endotoxin reduction would be useful as a therapy for pediatric NAFLD.

Background: Congenital coronary anomalies may be isolated, or they may accompany other congenital heart defects, such as Fallot's tetralogy, transposition of the great arteries or pulmonary atresia. The most common cause of acquired abnormalities of the coronary vessels in children is kawasaki disease (KD). The aim of this study was to find the best model to obtain valid and normally distributed Z-scores for coronary artery (CA) diameters in a large, heterogeneous population of healthy children.Methods: Echocardiography was performed on 300 healthy children. Linear regression models were tested with height, weight, body surface area, and aortic valve diameter. The computed Z scores were tested for normal distribution and stability. Results: CA diameter was best predicted using regression with the body surface area and age in month. The weighted least squares method yielded normally distributed and very stable Z-score estimates for 3 principal CAs.Conclusions: This study showed valid methods to estimate Z scores for CA size in children of all ages. Such Z scores are important for risk stratification in patients with Kawasaki disease.

Abstract Background Physical activity (PA) patterns in children with juvenile idiopathic arthritis (JIA) over time are not well described. The aim of this study was to describe associations of physical activity (PA) with disease activity, function, pain, and psychosocial stress in the 2 years following diagnosis in an inception cohort of children with juvenile idiopathic arthritis (JIA). Methods In 82 children with newly diagnosed JIA, PA levels, prospectively determined at enrollment, 12 and 24 months using the Physical Activity Questionnaire for Children (PAQ-C) and Adolescents (PAQ-A) raw scores, were evaluated in relation to disease activity as reflected by arthritis activity (Juvenile Arthritis Disease Activity Score (JADAS-71)), function, pain, and psychosocial stresses using a linear mixed model approach. Results in the JIA cohort were compared to normative Pediatric Bone Mineral Accrual Study data derived from healthy children using z-scores. Results At enrollment, PA z-score levels of study participants were lower than those in the normative population (median z-score − 0.356; p = 0.005). At enrollment, PA raw scores were negatively associated with the psychosocial domain of the Juvenile Arthritis Quality of Life Questionnaire (r = − 0.251; p = 0.023). There was a significant decline in PAQ-C/A raw scores from baseline (median and IQR: 2.6, 1.4–3.1) to 24 months (median and IQR: 2.1, 1.4–2.7; p = 0.003). The linear mixed-effect model showed that PAQ-C/A raw scores in children with JIA decreased as age, disease duration, and ESR increased. The PAQ-C/A raw scores of the participants was also negatively influenced by an increase in disease activity as measured by the JADAS-71 (p <  0.001). Conclusion Canadian children with newly diagnosed JIA have lower PA levels than healthy children. The decline in PA levels over time was associated with disease activity and higher disease-specific psychosocial stress.

(1) Background: High sugar intake is prevalent among children and is associated with non-alcoholic fatty liver disease (NAFLD). The purpose of this study is to determine if a high intake of free sugars and sugary beverages (SB) in childhood is associated with NAFLD in adulthood; (2) Methods: At 24 years, 3095 participants were assessed for severe hepatic steatosis (controlled attenuation parameter >280 dB/m) and had dietary data collected via a food frequency questionnaire at age three years. Multiple logistic regression models adjusted for total energy intake, potential confounders, and a mediator (offspring body mass index (BMI) at 24 years); (3) Results: Per quintile increase of free sugar intake association with severe hepatic steatosis at 24 years after adjusting for total energy was odds ratio (OR):1.07 (95% CL: 0.99–1.17). Comparing the lowest vs. the highest free sugar consumers, the association was OR:1.28 (95% CL: 0.88–1.85) and 1.14 (0.72, 1.82) after full adjustment. The OR for high SB consumption (>2/day) compared to <1/day was 1.23 (95% CL: 0.82–1.84) and OR: 0.98 (95% CL: 0.60–1.60) after full adjustment; (4) Conclusions: High free sugar and SB intake at three years were positively but weakly associated with severe hepatic steatosis at 24 years. These associations were completely attenuated after adjusting for confounders and 24-year BMI.

This study proposes age- and sex-specific percentiles for serum cobalamin and folate, and analyzes the effects of sex, age, body mass index (BMI), and socioeconomic status (SES) on cobalamin and folate concentrations in healthy children and adolescents. In total, 4478 serum samples provided by healthy participants (2 months–18.0 years) in the LIFE (Leipzig Research Centre for Civilization Diseases) Child population-based cohort study between 2011 and 2015 were analyzed by electrochemiluminescence immunoassay (ECLIA). Continuous age-and sex-related percentiles (2.5th, 10th, 50th, 90th, 97.5th) were estimated, applying Cole’s LMS method. In both sexes, folate concentrations decreased continuously with age, whereas cobalamin concentration peaked between three and seven years of age and declined thereafter. Female sex was associated with higher concentrations of both vitamins in 13- to 18-year-olds and with higher folate levels in one- to five-year-olds. BMI was inversely correlated with concentrations of both vitamins, whilst SES positively affected folate but not cobalamin concentrations. To conclude, in the assessment of cobalamin and folate status, the age- and sex-dependent dynamic of the respective serum concentrations must be considered. While BMI is a determinant of both vitamin concentrations, SES is only associated with folate concentrations.

AbstractIn obese adults, nonalcoholic fatty liver disease (NAFLD) is accompanied by multiple metabolic dysfunctions. Although upregulated hepatic fatty acid synthesis has been identified as a crucial mediator of NAFLD development, the underlying mechanisms are yet to be elucidated. In this study, we reported upregulated expression of gene related to anergy in lymphocytes (GRAIL) in the livers of humans and mice with hepatic steatosis. Grail ablation markedly alleviated the high-fat diet-induced hepatic fat accumulation and expression of genes related to the lipid metabolism, in vitro and in vivo. Conversely, overexpression of GRAIL exacerbated lipid accumulation and enhanced the expression of lipid metabolic genes in mice and liver cells. Our results demonstrated that Grail regulated the lipid accumulation in hepatic steatosis via interaction with sirtuin 1. Thus, Grail poses as a significant molecular regulator in the development of NAFLD.
