Enfermedad de la orina con olor a jarabe de arce - Overview

Nombres alternativos

EOOJA

Definición:

Es un trastorno del metabolismo transmitido de padres a hijos, en el cual el cuerpo no puede descomponer ciertas partes de proteínas. La orina en las personas con esta enfermedad puede oler a jarabe de arce.

Causas:

La enfermedad de la orina con olor a jarabe de arce (EOOJA) es causada por una anomalía genética. Las personas con esta afección no pueden metabolizar los aminoácidos leucina, isoleucina y valina, lo cual lleva a una acumulación de estos químicos en la sangre.

En su forma más grave, esta enfermedad puede dañar el cerebro durante momentos de estrés físico (como infección, fiebre o no consumir alimentos por un tiempo prolongado).

Algunos tipos de esta enfermedad son leves o aparecen y desaparecen. Aun en su forma más leve, los períodos repetitivos de estrés físico pueden provocar retardo mental y altos niveles de leucina.
