Inborn Errors Of Metabolism Made Easy
JavaScript. Inborn errors of metabolism are rare genetic (inherited) disorders in which the body cannot properly turn food inborn errors of metabolism ppt into energy. The disorders are usually caused by defects in specific proteins (enzymes) that help break down (metabolize) parts of food. A food product that is not broken down into inborn errors of metabolism pdf energy can build up in the body and cause a wide range of symptoms. Several inborn errors of metabolism cause developmental delays or other medical problems if they are not controlled. There are many different types of inborn errors of metabolism. A few of them are:Fructose intoleranceGalactosemiaMaple sugar urine disease (MSUD)Phenylketonuria (PKU) Newborn screening tests can identify some of these disorders.Registered

Presentation is usually in the neonatal period or infancy but can occur at any time, even in adulthood. Diagnosis does not require extensive knowledge of biochemical pathways or individual metabolic diseases. An understanding of the major clinical manifestations of inborn errors of metabolism provides http://emedicine.medscape.com/article/804757-overview the basis for knowing when to consider the diagnosis. A high index of suspicion is most important in making the diagnosis. For patients with suspected or known inborn errors of metabolism, successful emergency treatment depends on prompt institution of therapy aimed at metabolic stabilization. Asymptomatic neonates with newborn screening results positive for an inborn error of metabolism may require emergent evaluation including confirmatory testing, and as appropriate, initiation of disease-specific management. Next Pathophysiology Single gene defects result in abnormalities in the synthesis or catabolism of proteins, carbohydrates, fats, or complex molecules. Most are due to a defect in an enzyme or transport protein, which results in a block in a metabolic pathway. Effects are due to toxic accumulations of substrates before the block, intermediates from alternative metabolic pathways, defects in energy production and use caused by a deficiency of products beyond the block, or a combination of these metabolic deviations. Nearly every metabolic disease has several forms that vary in age of onset, clinical severity, and, often, mode of inheritance. Categories of inborn errors of metabolism, or IEMs, are as follows: Disorders that result in toxic accumulat

Burton Article Figures & Data Info & Metrics Comments Download PDF AbstractRecent advances in the diagnosis and treatment of inborn errors of metabolism have improved substantially the prognosis for many of these conditions. This inborn error makes it essential that the practicing pediatrician be familiar with the clinical presentation of these disorders. A practical clinical approach to the recognition of inborn errors of metabolism in the young infant is presented in this review. Indications for specific laboratory studies are discussed. Guidelines are provided for the stabilization and emergency treatment of critically ill inborn errors of infants. This approach will identify those infants who will benefit from additional evaluation and specific treatment.Many of the inborn errors of metabolism, including urea cycle defects, organic acidemias, and certain disorders of amino acid metabolism, present in the young infant with symptoms of an acute or chronic metabolic encephalopathy. Typical symptoms include lethargy, poor feeding, apnea or tachypnea, and recurrent vomiting. Metabolic acidosis and/or hyperammonemia are observed in many of these conditions, but there are notable exceptions, including nonketotic hyperglycinemia and molybdenum co-factor deficiency. Therefore, appropriate laboratory testing for metabolic disorders should be performed in any infant who exhibits these findings. Although sepsis may be the initial consideration in a neonate with these symptoms, inborn errors of metabolism should always be in the differential diagnosis, particularly in a full-term infant with no specific risk factors.Hypoglycemia may be the predominant finding in a number of inborn errors of metabolism, including glycogen storage disorders, defects in gluconeogenesis, and fatty acid oxidation defects. The latter disorders, among the m
