We assessed the performance of magnetic resonance imaging (MRI) proton density fat fraction (PDFF) in children to stratify hepatic steatosis grade before and after treatment in the Cysteamine Bitartrate Delayed-Release for the Treatment of Nonalcoholic Fatty Liver Disease in Children (CyNCh) trial, using centrally-scored histology as reference. Participants had multi-echo 1.5T or 3T MRI on scanners from three manufacturers. Of 169 enrolled children, 110 (65%) and 83 (49%) had MRI and liver biopsy at baseline and at end-of-treatment (EOT; 52-weeks), respectively...

Variable drug responses(VDRs) are dependent upon individual variation in the activity of drug-metabolizing enzymes including cytochrome P450s(CYPs). As the most common chronic liver disease in children and adults, nonalcoholic steatohepatitis(NASH) has been identified as a source of significant inter-individual variation in hepatic drug metabolism. Compared to adults, children present age-related differences in pharmacokinetics and pharmacodynamics. The purpose of this study was to determine the impact of fatty liver disease severity on the activity of a variety of CYPs in children and adolescents...

Nonalcoholic fatty liver disease (NAFLD) is the liver disease associated with obesity, diabetes and the metabolic syndrome . Although steatosis is a key histological feature, liver biopsies of patients with NAFLD can show a wide range of other findings, including portal and lobular inflammation, ballooning and apoptotic hepatocellular injury, Mallory-Denk bodies, megamitochondria and fibrosis. Nonalcoholic steatohepatitis (NASH) is a progressive subtype of NAFLD first defined by analogy to alcoholic hepatitis...

NAFLD is one of the most important causes of liver disease worldwide and will probably emerge as the leading cause of end-stage liver disease in the coming decades, with the disease affecting both adults and children. The epidemiology and demographic characteristics of NAFLD vary worldwide, usually parallel to the prevalence of obesity, but a substantial proportion of patients are lean. The large number of patients with NAFLD with potential for progressive liver disease creates challenges for screening, as the diagnosis of NASH necessitates invasive liver biopsy...

Dental therapists are members of the oral health workforce in over 50 countries in the world typically caring for children in publically funded school-based programs. A movement has developed in the United States to introduce dental therapists to the oral health workforce in an attempt to improve access to care and to reduce disparities in oral health. This article critiques trends in the United States movement in the context of the history and success of dental therapists practicing internationally. While supporting the dental therapist movement, we challenge: a) the use of dental therapists treating adults, versus focusing on children; b) the use of dental therapists in the private versus the public/not-for-profit sector; and c) requirements that a dental therapist must also be credentialed as a dental hygienist...

BACKGROUND: Helminth infections, common in low income countries, may protect against allergy-related disease. Early exposure may be key. In the Entebbe Mother and Baby Study, treating helminths during pregnancy resulted in increased eczema rates in early childhood. We followed the cohort to determine whether this translated to increased asthma rates at school-age. METHODS: This randomized, double-blind, placebo-controlled trial, conducted in Entebbe, Uganda, had three interventions...

Prenatal alcohol exposure is the cause of fetal alcohol spectrum disorders (FASDs), the prevalence of which is similar to that of other developmental disabilities like Down syndrome and autism. Children, adolescents, and adults who live with the disabilities associated with prenatal alcohol exposure face extraordinary challenges throughout their lives. Pediatric providers need to be able to identify patients with FASD because early recognition and intervention is known to improve life outcomes for affected individuals...

Non-alcoholic fatty liver disease (NAFLD) represents a spectrum, including 'simple' steatosis, non-alcoholic steatohepatitis (NASH), and fibrosis. Increasing prevalence of NAFLD has followed the international rise in obesity and lifestyle modification is the mainstay therapy for children. To date, pharmacological trials have had varying efficacy but a large number of new agents are in early phase trials for adults. Areas covered: This review explores the effect of current and potential future paediatric NAFLD treatments in terms of histological and biochemical endpoints...

Non-invasive diagnosis and quantification of liver steatosis is important to overcome limits of liver biopsy, in order to follow up patients during their therapy and to establish a reference standard that can be used in clinical trials and longitudinal studies. Imaging offers several methods in this setting: ultrasound, which is the cheapest technique and easy to perform; magnetic resonance spectroscopy (MRS), which reflects the real content of triglycerides in a specific volume; and proton density fat fraction (PDFF) magnetic resonance, which is a simple method that reflects the distribution of the fat in the whole liver...

Non-alcoholic fatty liver disease (NAFLD) is the most frequent type of chronic liver disease in the pediatric age group, paralleling an obesity pandemic. A "multiple-hit" hypothesis has been invoked to explain its pathogenesis. The "first hit" is liver lipid accumulation in obese children with insulin resistance. In the absence of significant lifestyle modifications leading to weight loss and increased physical activity, other factors may act as "second hits" implicated in liver damage progression leading to more severe forms of inflammation and hepatic fibrosis...

BACKGROUND & AIMS: Treatment with the farnesoid X receptor (FXR) agonist obeticholic acid is ineffective in some patients with non-alcoholic steatohepatitis (NASH) but the explanation is uncertain. We investigated hepatic FXR expression, and measurements of fibroblast growth factor 19 (FGF19) and bile acids (BAs) in children with NAFLD to investigate relationships with NASH. METHODS: 33 children with NAFLD who underwent diagnostic liver biopsy were studied. Hepatic FXR protein levels and circulating FGF19 concentrations were compared with those analysed in five control subjects with proven normal liver histology...

OBJECTIVES: Hemoglobin (Hb) and red blood cell distribution width (RDW) have been reported to be a risk marker of metabolic syndrome and nonalcoholic fatty liver disease (NAFLD). No study exists on pediatric populations. We aimed to determine the association between hematological parameters, and the severity of disease in children with biopsy-proven NAFLD. METHODS: A total of 117 children (85 boys, mean age 12 years) with ultrasound evidence of NAFLD undergoing liver biopsy for diagnosis of nonalcoholic steatohepatitis (NASH), were prospectively enrolled between January 2011 and May 2013 in the setting of a tertiary care center...

Nonalcoholic fatty liver disease (NAFLD) is highly prevalent and can lead to cirrhosis, hepatocellular carcinoma, and end-stage liver disease. NAFLD comprises the spectrum from simple steatosis (nonalcoholic fatty liver, NAFL), to steatosis with inflammation (nonalcoholic steatohepatitis, NASH). Current primary therapy recommended for NAFLD is weight loss induced by lifestyle modification. The difficulty in achieving this has led to robust pharmacological therapy development. While new drugs may show efficacy in selected phase II/III clinical trial populations, their real-world effectiveness is unknown...

INTRODUCTION: Traffic-related air pollution causes fatty liver, inflammation and fibrosis in animal models, but there have been few studies in humans. OBJECTIVES: To test the hypothesis that traffic-related air pollution causes non-alcoholic fatty liver disease (NAFLD) and increased markers for non-alcoholic steatohepatitis (NASH); and that NAFLD increases liver susceptibility to increased NASH risk. METHODS: Data collected prospectively from 74 overweight or obese children were obtained from the Yale Pediatric Obesity Clinic...

Non-alcoholic fatty liver disease (NAFLD) is characterized by liver fat accumulation and non-alcoholic steatohepatitis (NASH) with inflammation and fibrosis, which may lead to cirrhosis also in childhood. NAFLD/NASH in children are related to obesity and the metabolic syndrome, and incidence and prevalence are expected to increase. Children having liver steatosis and elevated liver enzymes are most often asymptomatic, and a liver biopsy is necessary for correct diagnosis and staging. The treatment should focus on lifestyle changes, as pharmacological therapy needs further evaluation...
