Daño fetal a pesar de la dieta baja en fenilalanina después de la concepción en una mujer fenilcetonúrica
Lancet (London, England)
|January 6, 1979
Resumen
La fenilcetonuria materna puede causar daño fetal como defectos cardíacos y microcefalia. La intervención dietética temprana es crucial, ya que el daño puede ocurrir a las pocas semanas de la concepción, incluso con un tratamiento posterior.
Área de la Ciencia:
- La bioquímica es la bioquímica.
- Genética La genética.
- La medicina materno-fetal es una de ellas.
Sus antecedentes:
- La fenilcetonuria (PKU) es un trastorno metabólico hereditario.
- Los niveles elevados de fenilalanina durante el embarazo plantean riesgos para el desarrollo fetal.
- El manejo materno de la PKU generalmente implica la restricción de la fenilalanina en la dieta.
Objetivo del estudio:
- Para investigar el momento del daño fetal en la fenilcetonuria materna.
- Evaluar la eficacia de la intervención dietética de aparición tardía en la prevención de anomalías congénitas.
Principales métodos:
- Estudio de caso de una mujer con fenilcetonuria.
- Revisión del manejo del embarazo y los resultados infantiles.
Principales resultados:
- Niño nacido con defecto cardíaco y microcefalia.
- La dieta baja en fenilalanina se inició 5 semanas después de la concepción (3 semanas después de la pérdida del período).
- Es probable que el daño fetal ocurriera temprano en la gestación.
Conclusiones:
- La fenilcetonuria materna plantea riesgos significativos para el desarrollo fetal.
- El daño, incluyendo malformaciones cardíacas y microcefalia, puede ocurrir muy temprano en el embarazo.
- La intervención dietética para la PKU materna debe iniciarse preconcepcionalmente para obtener resultados óptimos.

01:23Urea Cycle
The urea cycle describes how liver cells convert ammonia to urea. Ammonia is a toxic waste product of protein catabolism. Land animals must convert ammonia into the less toxic urea which can be safely eliminated by the kidneys through urine. Marine animals excrete ammonia directly, and the surrounding water dilutes the ammonia to safe levels.

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:21Overview of Protein Metabolism
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

01:20Pathophysiology of Diabetes
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
