Metabolic syndrome children

Jocelyn M Bischof, Rachel Wevrick
Excess fat mass is a cardinal feature of Prader-Willi syndrome (PWS) that is recapitulated in the Magel2-null mouse model of this genetic disorder. There is a pressing need for drugs that can prevent or treat obesity in children with PWS. Recently, a clinical study of a controlled release form of the benzothiadiazine derivative diazoxide demonstrated improved metabolic parameters and decreased fat mass in obese children and adults with PWS. We tested whether chronic diazoxide administration can reduce fat mass and improve metabolism in mice lacking MAGEL2, a gene inactivated in PWS...

BACKGROUND: Metabolic syndrome (MetS) is a complex and multifactorial disorder characterized by insulin resistance, dyslipidaemia, hyperglycemia, abdominal obesity, and elevated blood pressure. The apolipoprotein A5 (APOA5) gene variants have been reported to correlate with two major components of MetS, including low levels of high density lipoprotein cholesterol (HDL-C) and high levels of triglyceride. In the present study, we explored the associations between five single nucleotide polymorphisms (SNPs) of APOA5 gene and the MetS risk...

Acute kidney injury (AKI) is a common accompaniment in patients with liver disease. The causes, risk factors, manifestations and management of AKI in these patients vary according to the liver disease in question (acute liver failure, acute-on-chronic liver failure, post-liver transplantation or metabolic liver disease). There are multiple causes of AKI in patients with liver disease-pre-renal, acute tubular necrosis, post-renal, drug-induced renal failure and hepatorenal syndrome (HRS). Definitions of AKI in liver failure are periodically revised and updated, but pediatric definitions have still to see the light of the day...

Premature adrenarche (PA) has been assumed to be a benign variant of normal pubertal development. Yet, current collective information suggests associations between PA and potential risks for development of polycystic ovary syndrome and adult diseases such as the metabolic syndrome. Adrenarche refers to the increased secretion of the adrenal androgen precursors DHEA, DHEAS, and androstenedione, which normally occurs in children at age 6-8 years. PA may be identified clinically by early pubarche, which is defined as the development of pubic or axillary hair before 8 years in girls or 9 years in boys...

BACKGROUND AND OBJECTIVES: Nonalcoholic fatty liver disease (NAFLD) disproportionately affects Hispanic boys. Further, obesity and insulin resistance are major risk factors for NAFLD. No gene localization studies had been performed on children with biopsy-proven NAFLD. This study aims to identify genomic variants associated with increased adiposity and insulin resistance in a population of children with varying histologic severity of NAFLD. METHODS: We conducted a genome-wide association scan (GWAS) including 624,297 single-nucleotide polymorphisms (SNPs) distributed among all 22 autosomal chromosomes in 234 Hispanic boys (up to 18 years of age) who were consecutively recruited in a prospective cohort study in the Nonalcoholic Steatohepatitis Clinical Research Network Studies...

BACKGROUND: Obesity during adolescence is associated with cardiovascular mortality in adulthood. The adverse obesity-related cardiometabolic risk profile is already observed in adolescence. We aimed to examine possible gender differences in cardiometabolic risk factors and lifestyle behaviors among adolescents with severe obesity, hypothesizing that boys would have both a higher prevalence of the metabolic syndrome as well as less healthy lifestyle behaviors than girls. METHODS: Cross-sectional study of treatment-seeking adolescents with severe obesity who attended the Morbid Obesity Centre at Vestfold Hospital Trust and who were consecutively enrolled in the Vestfold Register of Obese Children between September 2009 and September 2015...

Total esophagogastric dissociation (TED) is used to treat gastroesophageal reflux (GER) after failed fundoplication in neurologically impaired patients. It is now performed for some otherwise healthy patients with severe GER. In this procedure, the gastrointestinal tract is reconstructed in a non-physiological way with a Roux-en-Y esophagojejunal anastomosis and jejuno-jejunostomy. Although TED eliminates almost all GER, some patients experience late complications. In this review, we investigated the long-term outcomes after TED to determine the best indications...

BACKGROUND: Intravenous (IV) arginine has been reported to ameliorate acute metabolic stroke symptoms in adult patients with Mitochondrial Encephalopathy with Lactic Acidosis and Stroke-like Episodes (MELAS) syndrome, where its therapeutic benefit is postulated to result from arginine acting as a nitric oxide donor to reverse vasospasm. Further, reduced plasma arginine may occur in mitochondrial disease since the biosynthesis of arginine's precursor, citrulline, requires ATP. Metabolic strokes occur across a wide array of primary mitochondrial diseases having diverse molecular etiologies that are likely to share similar pathophysiologic mechanisms...

Children are at increased risk of developing metabolic syndrome (MS) after kidney transplantation, which contributes to long-term cardiovascular (CV) morbidities and decline in allograft function. While MS in the general population occurs due to excess caloric intake and physical inactivity, additional chronic kidney disease and transplant-related factors contribute to the development of MS in transplant recipients. Despite its significant health consequences, the interplay of the individual components in CV morbidity in pediatric transplant recipients is not well understood...

OBJECTIVES: To describe our initial experience in the treatment of hyperparathyroidism (HPP) of renal cause using total or subtotal parathyroidectomy, autoimplant and cryopreservation in pediatric patients. Secondary HPP is the increased function of the parathyroid hormone (PTH) due to an abnormal phosphocalcic metabolism in patients with chronic renal failure (CRF). This situation produces increased bone resorption resulting in osteodystrophy and endovascular calcifications. Surgical treatment is aimed to diminish the level of PTH in CRF patients, to avoid HPP complications...

Early signs of subclinical CV dysfunction can be detected by ultrasound for CIMT. Although A-A are at high risk for CV disease, CIMT of A-A kidney transplant recipients has not been previously investigated. The aim of this prospective, controlled, longitudinal study was to investigate determinants of CIMT in a multiracial pediatric kidney transplant population, with a focus on A-A. Transplant recipients (n = 42) had BMI, waist-to-height ratio, fasting glucose, lipid panel, HbA1c%, and CIMT measured at 1, 18, and 30 months post-transplant...
