Primary carnitine deficiency (PCD) is an inherited disease of fatty acid beta-oxidation with autosomal recessive inheritance. The disease manifests as metabolic decompensation with hypoketotic hypoglycaemia associated with cardiomyopathy, hepatomegaly, rhabdomyolysis, and seizures. Various outcomes are described from asymptomatic adults to dramatic sudden infant death syndrome cases. We present a severe case of PCD decompensation in an 18-week-old female. She presented with hypotonia, moaning, diarrhea, and vomiting at the pediatric emergency. Initially suspected as intracranial hypertension, the clinical condition evolved rapidly and caused a reversible cardiac arrest with profound hypoglycemia. Despite carnitine supplementation, she succumbed from cardiac arrhythmia and multivisceral failure 4 days after admission. The genetic analyses showed a PCD with biallelic pathogenic variants of gene. The case report is notable for the severity of the cardiac damage possibly favored by maternal carnitine deficiency during pregnancy. The analysis of previously published PCD cases highlights (i) the importance of having large access to emergency biochemical tests for early therapeutic care although the disease has unpredictable severity and (ii) the fact that the clinical outcome remains unpredictable if carnitine treatment is initiated late

Fortification of Human Milk for Preterm Infants: Update and Recommendations of the European Milk Bank Association (EMBA) Working Group on Human Milk Fortification

Evidence indicates that human milk (HM) is the best form of nutrition uniquely suited not only to term but also to preterm infants conferring health benefits in both the short and long-term. However, HM does not provide sufficient nutrition for the very low birth weight (VLBW) infant when fed at the usual feeding volumes leading to slow growth with the risk of neurocognitive impairment and other poor health outcomes such as retinopathy and bronchopulmonary dysplasia. HM should be supplemented (fortified) with the nutrients in short supply, particularly with protein, calcium, and phosphate to meet the high requirements of this group of babies. In this paper the European Milk Bank Association (EMBA) Working Group on HM Fortification discusses the existing evidence in this field, gives an overview of different fortification approaches and definitions, outlines the gaps in knowledge and gives recommendations for practice and suggestions for future research. EMBA recognizes that “Standard Fortification,” which is currently the most utilized regimen in neonatal intensive care units, still falls short in supplying sufficient protein for some VLBW infants. EMBA encourages the use of “Individualized Fortification” to optimize nutrient intake. “Adjustable Fortification” and “Targeted Fortification” are 2 methods of individualized fortification. The quality and source of human milk fortifiers constitute another important topic. There is work looking at human milk derived fortifiers, but it is still too early to draw precise conclusions about their use. The pros and cons are discussed in this Commentary in addition to the evidence around use of fortifiers post discharge

Zinc Therapy for Wilson Disease in Children in French Pediatric Centers:

International audienceBackground and Aims: Zinc therapy is considered a good option in Wilson disease (WD), as a first-line treatment in presymptomatic children and a maintenance therapy after the initial chelator therapy. The aim of the study was to determine the practical use of zinc treatment in French pediatric centers. Methods: A national survey was conducted in the 6 French centers using zinc acetate to treat WD. Clinical and biological parameters, dosage, and outcome were recorded. Results: A total of 26 children were reported to be treated with zinc acetate, alone or in association with chelators. Of the 9 children (35%) who received zinc alone as a first-line therapy, 2 were switched to D-penicillamine because of inefficacy and 7 remained on zinc alone, but serum transaminase levels normalized in only 4 of them. Five children (19%) were initially treated with zinc in association with D-penicillamine (n = 4) or Trientine (n = 1) with good efficacy. Among the 12 children (46%) who received zinc as a maintenance therapy after D-penicillamine, no relapse of hepatic cytolysis occurred during a median follow-up of 5.2 years, but 2 of them were switched to Trientine because of zinc-related adverse effects. Epigastric pain was observed in 4 children, and a gastric perforation occurred in 1 child. Conclusions: The present study demonstrates poor efficacy of zinc as first-line therapy to control liver disease in half presymptomatic children and a high incidence of related gastrointestinal adverse effects in children with WD

Letter to the editor: clarifying some aspects and the terminology of individualized human milk fortification

Abstract This letter has been written by the components of the European Milk Bank Association (EMBA) Working Group on Human Milk Fortification in response to a recent paper published by Mathes et al. (BMC Pediatr. 2018 May 8;18(1):154) with the aim of drawing attention to the importance of the use of a metabolic marker to adapt protein intake in preterm infants. EMBA Working Group on Human Milk Fortification clarifies further the terminology and some specific aspects regarding individualized human milk fortification. There are two types of individualized human milk fortification: Adjustable human milk fortification and Targeted human milk fortification. Advantages and disadvantages of these methods are summarized
