Cribado neonatal para la deficiencia de la acil-CoA deshidrogenasa de cadena media
Lancet (London, England)
|October 9, 2001
Resumen
En el Reino Unido se recomienda el cribado de recién nacidos para la deficiencia de acil-CoA deshidrogenasa de cadena media (MCAD). El análisis de acilcarnitina en manchas de sangre muestra una alta especificidad, lo que apoya la detección temprana de este trastorno grave.
Área de la Ciencia:
- La bioquímica es la bioquímica.
- Genética La genética.
- Medicina Neonatal La medicina neonatal es una especialidad de la medicina neonatal.
Sus antecedentes:
- El cribado neonatal para la deficiencia de acil-CoA deshidrogenasa de cadena media (MCAD) no es estándar en el Reino Unido.
- La incertidumbre con respecto a la historia natural del trastorno y la especificidad de las pruebas de detección son las principales barreras.
- Este estudio aborda estas preocupaciones a través de un análisis retrospectivo.
Objetivo del estudio:
- Para evaluar la historia natural y la especificidad de la prueba de cribado para la deficiencia de MCAD.
- Proporcionar datos que apoyen la posible introducción de la detección de deficiencia de MCAD en el Reino Unido.
Principales métodos:
- Análisis retrospectivo de las concentraciones de acilcarnitina en las manchas de sangre neonatales almacenadas.
- Revisión de pacientes identificados con altos niveles de octanoilcarnitina a los 7-9 años de edad.
Principales resultados:
- El análisis de acilcarnitina demostró una alta especificidad para identificar la deficiencia de MCAD.
- El estudio destacó la significativa morbilidad y mortalidad asociadas con la deficiencia de MCAD no tratada.
Conclusiones:
- Los hallazgos apoyan la introducción del cribado neonatal para la deficiencia de MCAD en el Reino Unido.
- El análisis de acilcarnitina es un método confiable para detectar la deficiencia de MCAD en recién nacidos.

01:28Overview of Fatty Acid Metabolism
Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

01:23Cystic Fibrosis: Pathogenesis
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

01:20Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
01:24Pharmacokinetics in Pediatric Patients: Drug Metabolism
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...
01:18Amino Acid Catabolism
Microorganisms rely on proteins as an essential carbon and energy source, particularly in environments with limited polysaccharides or lipids. However, proteins are too large to cross the plasma membrane unaided, necessitating enzymatic degradation. Microbes secrete extracellular proteases and peptidases that hydrolyze proteins into peptides, which can then be transported across the membrane. Once inside the cell, intracellular proteases degrade these peptides into free amino acids, which...
01:25Lipid Catabolism
Triglycerides serve as crucial long-term energy storage molecules in microorganisms, providing a dense source of metabolic energy. Their breakdown is mediated by lipases, which hydrolyze triglycerides into glycerol and free fatty acids. Each of these components follows distinct metabolic pathways, ultimately contributing to ATP synthesis and cellular energy homeostasis.Glycerol MetabolismGlycerol, released from triglyceride hydrolysis, is phosphorylated by glycerol kinase to form...
