RESUMEN
Actualmente, las enfermedades cardiovasculares son la primera causa de muerte a nivel mundial. Aunque, este tipo depatologías afectan en mayor proporción a adultos mayores, su proceso inicia desde la infancia. Hoy por hoy la hiperhomocisteinemia/homocisteinuria se ha considerado un factor de riesgo cardiovascular independiente y tan importante o másque otros clásicos. Existen cada vez más evidencias que resulta necesario identificar a tiempo esta alteración y procedera su tratamiento preventivo. Algunas de las causas para padecer esta patología en edad temprana son; la insuficienteingestión de ácido fólico, vitamina B6 o vitamina B12, las cuales son un conjunto de vitaminas importantes que funcionancomo cofactores de la 5-10-metilentetrahidrofolato reductasa (MTHFR), cistationina β sintetasa (CBS) y metionina adenosiltransferasa(MAT); tres enzimas principales del metabolismo de la homocisteína. Sin embargo, aún no se conoce en sutotalidad las consecuencias del incremento de homocisteína en niños y jóvenes.
ABSTRACT
Currently, cardiovascular disease is the leading cause of death worldwide. Although, this type of disease affects a greaterproportion to older adults, the process starts since childhood. Today, hyperhomocysteinemia has been considered anindependent cardiovascular risk factor, as important or more than other classic factors. There is increasing evidence thattime is necessary to identify the disorder and provide treatment for prevention. Some of the reasons for developingthis disease at an early age the insufficient intake of folic acid, vitamin B6 and vitamin B12, which are a set of importantvitamins that act as cofactors 5-10-methylenetetrahydrofolate reductase (MTHFR), cystathionine β synthase (CBS) andmethionine adenosyltransferase (MAT), three major enzymes of homocysteine metabolism. However, still not fully knownconsequences of homocysteine increase in children and youth.
