ABSTRACT

Aunque, con tratamiento precoz, los pacientes con fenilcetonuria pueden presentar niveles de inteligencia normales, es importante optimizar el control dietético para mantener niveles de fenilalanina adecuados y poder desarrollar su potencial intelectual sin alteraciones en sus tareas diarias por déficits en las funciones ejecutivas. Se presenta una serie de 26 pacientes, diagnosticados y tratados precozmente, a quienes se realizó una evaluación psicométrica junto con determinaciones de fenilalanina a lo largo de su vida y en el momento de realización de los tests. Se observa una tendencia a la relación inversa entre el cociente intelectual y la fenilalanina concurrente, la mediana de fenilalanina y el cociente fenilalanina/tirosina, así como una tendencia a la relación negativa entre las funciones ejecutivas y los valores de fenilalanina concurrentes y durante la vida.


Although with early treatment phenylketonuria patients may have average intelligence levels, it is important to optimize the nutritional management to maintain adequate phenylalanine levels, so that patients can develop their intellectual potential free of abnormalities in their daily activities due to deficits of cognitive executive functions. This study presents a series of 26 patients, diagnosed and treated early, who underwent a psychometric evaluation together with phenylalanine determinations along their lives, and at the time of doing the tests. A trend is observed towards a reverse relationship between IQ and concurrent phenylalanine concentration, phenylalanine median and phenylalanine/tyrosine ratio. Likewise, a trend towards a negative relationship is observed between executive functions and concurrent phenylalanine values along patients' lives.
