Atypical Reye syndrome: three cases of a problem that pediatricians should consider and remember.

Acta Biomed 2021 04 30;92(S1):e2021110. Epub 2021 Apr 30.

Institute of Pediatrics, Fondazione Policlinico A. Gemelli IRCCS - Università Cattolica Sacro Cuore, Rome, Italy .

Introduction: Reye syndrome is a rare acquired metabolic disorder appearing almost always during childhood. Its aetiopathogenesis, although controversial, is partially understood. The classical disease is typically anticipated by a viral infection with 3-5 days of well-being before the onset of symptoms, while the biochemical explanation of the clinical picture is a mitochondrial metabolism disorder, which leads to a metabolic failure of different tissues, especially the liver.

Physiological Perspectives on the Use of Triheptanoin as Anaplerotic Therapy for Long Chain Fatty Acid Oxidation Disorders.

Front Genet 2020 15;11:598760. Epub 2021 Jan 15.

Department of Pediatrics, School of Medicine, University of Pittsburgh, Pittsburgh, PA, United States.

Inborn errors of mitochondrial fatty acid oxidation (FAO) comprise the most common group of disorders identified through expanded newborn screening mandated in all 50 states in the United States, affecting 1:10,000 newborns. While some of the morbidity in FAO disorders (FAODs) can be reduced if identified through screening, a significant gap remains between the ability to diagnose these disorders and the ability to treat them. At least 25 enzymes and specific transport proteins are responsible for carrying out the steps of mitochondrial fatty acid metabolism, with at least 22 associated genetic disorders. Read More

Allergy Immunology Unit, Advanced Pediatrics Centre (APC), Post Graduate Institute of Medical Education and Research (PGIMER), Chandigarh, 160012, India.

Kawasaki disease (KD), an enigmatic medium vessel vasculitis, presents as an acute febrile illness predominantly affecting young children. KD appears to be a hyper-inflammatory response elicited by environmental or infectious agents (including respiratory viruses) in genetically predisposed individuals. Numerous reports from the current era of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic have described the occurrence of KD/KD-like illness in close temporal proximity to SARS-CoV-2 infection or exposure.

Adjuvant herbal therapy for targeting susceptibility genes to Kawasaki disease: An overview of epidemiology, pathogenesis, diagnosis and pharmacological treatment of Kawasaki disease.

Phytomedicine 2020 Apr 18;70:153208. Epub 2020 Mar 18.

State Key Laboratory of Quality Research in Chinese Medicine, Macau University of Science and Technology, Macau, China.

Background: Kawasaki disease (KD) is a self-limiting acute systemic vasculitis occur mainly in infants and young children under 5 years old. Although the use of acetylsalicylic acid (AAS) in combination with intravenous immunoglobulin (IVIG) remains the standard therapy to KD, the etiology, genetic susceptibility genes and pathogenic factors of KD are still un-elucidated.

Purpose: Current obstacles in the treatment of KD include the lack of standard clinical and genetic markers for early diagnosis, possible severe side effect of AAS (Reye's syndrome), and the refractory KD cases with resistance to IVIG therapy, therefore, this review has focused on introducing the current advances in the identification of genetic susceptibility genes, environmental factors, diagnostic markers and adjuvant pharmacological intervention for KD.

First Case Report of Primary Carnitine Deficiency Manifested as Intellectual Disability and Autism Spectrum Disorder.

Brain Sci 2019 Jun 13;9(6). Epub 2019 Jun 13.

Department of Nursing, University of Valencia, 46010 Valencia, Spain.

Systemic primary carnitine deficiency (PCD) is a genetic disorder caused by decreased or absent organic cation transporter type 2 (OCTN2) carnitine transporter activity, resulting in low serum carnitine levels and decreased carnitine accumulation inside cells. In early life, PCD is usually diagnosed as a metabolic decompensation, presenting as hypoketotic hypoglycemia, Reye syndrome, or sudden infant death; in childhood, PCD presents with skeletal or cardiac myopathy. However, the clinical presentation of PCD characterized by autism spectrum disorder (ASD) with intellectual disability (ID) has seldom been reported in the literature. Read More

Paediatr Anaesth 2014 Jul 2;24(7):717-23. Epub 2014 Apr 2.

Departments of Neurology and Anesthesiology, Perioperative and Pain Medicine, Division of Critical Care Medicine, Boston Children's Hospital and Harvard Medical School, Boston, MA, USA.

Paralytic poliomyelitis, Reye syndrome, Hemophilus Influenzae type B epiglottitis, bacterial meningitis, and meningococcal septic shock are catastrophic illnesses that in the last 60 years have shaped the development of pediatric intensive care. Neurocritical care has been at the forefront of our thinking and, more latterly, as a specialty we have had the technology and means to develop this focus, educate the next generation and show that outcomes can be improved-first in adult critical care and now the task is to translate these benefits to critically ill children. In our future we will need to advance interventions in patient care with clinical trials. Read More

Pediatric parechovirus infections.

J Clin Virol 2014 Jun 13;60(2):84-9. Epub 2014 Mar 13.

Department of Medical Microbiology, Division of Clinical Virology, The University of Groningen, University Medical Center Groningen, The Netherlands.

Human parechoviruses (HPeVs) are members of the large and growing family of Picornaviridae. Although 16 types have been described on the basis of the phylogenetic analyses of the VP1 encoding region, the majority of published reports relate to the HPeV types 1-8. In pediatrics, HPeV1, HPeV2 and HPeV4-8 mainly cause mild gastrointestinal or respiratory illness; only occasionally more serious diseases have been reported, including myocarditis, encephalitis, pneumonia, meningitis, flaccid paralysis, Reye syndrome and fatal neonatal infection.

Ran D Goldman

Can Fam Physician 2013 Aug;59(8):843-4

BC Children's Hospital, Department of Pediatrics, Room K4-226, Ambulatory Care Bldg, 4480 Oak St, Vancouver, BC V6H 3V4, Canada.

Question: Recently, I had a visit from a 5-year-old patient who had been given bismuth subsalicylate for a diarrheal illness by a local family physician during a trip to South America. Is this a practice we should encourage?

Answer: Research from developing countries has found the use of bismuth subsalicylate to be effective in shortening the duration of diarrheal illness. Despite these findings, its limited effectiveness and concerns about it potentially causing Reye syndrome, compliance, and cost are the key reasons it is not routinely recommended for children.

Sudden unexpected infant death (SUDI) in a newborn due to medium chain acyl CoA dehydrogenase (MCAD) deficiency with an unusual severe genotype.

Ital J Pediatr 2012 Oct 24;38:59. Epub 2012 Oct 24.

Department of Pediatrics, University of Torino, Regina Margherita Children's Hospital, Torino, Italy.

Medium chain acyl CoA dehydrogenase deficiency (MCAD) is the most common inborn error of fatty acid oxidation. This condition may lead to cellular energy shortage and cause severe clinical events such as hypoketotic hypoglycemia, Reye syndrome and sudden death. MCAD deficiency usually presents around three to six months of life, following catabolic stress as intercurrent infections or prolonged fasting, whilst neonatal-onset of the disease is quite rare.

Antiplatelet therapy in children: why so different from adults'?

Curr Pharm Des 2012 ;18(21):3019-33

Department of Cardiovascular and Neurological Sciences, University of Cagliari, Italy.

Antiplatelet agents are administered in the treatment of a large number of adult diseases: coronary heart disease, ischemic stroke, peripheral arterial disease, arrhythmias with their thromboembolic complications, primary and secondary prevention. In childhood however, the situation is substantially different. The lack of large interventional trials on the use of antiplatelet drugs in children, has led to greater uncertainty, and a less extensive use of these drugs, limited to fewer indications. Read More
