Fenilcetonúria materna: relato de caso

Abstract: IntroduçãoAs hiperfenilalaninemias (HPA) são erros inatos do metabolismo, de herança autossômica recessiva, cujo distúrbio primário se localiza na conversão do aminoácido fenilalanina em tirosina por deficiência da enzima hepática fenilalaninahidroxilase (PAH). Em conseqüência disto, ocorre aumento da concentração de fenilalanina e de seus subprodutos no sangue e na urina (fenilpiruvato, fenilacetato, fenilactato e fenilacetilglutamina),

“…In consequence of this, occurs an increase of the phenylalanine concentration and its sub-products in the blood and urine (phenylpyruvate, phenylacetate, phenylactate and phenylacetylglutamine), with reduced formation of tyrosine. Serious cerebral damage are caused by the rise of the plasmatic concentration of phenylalanine in the organism, such as the competitive inhibition of the transport of the other necessary amino acids to the protein synthesis, weak formation or stabilization of polyribossome, reduced synthesis and increased degradation of myelin, as well as inadequate formation of norepinehrine and serotonin (Longo, 2002;Figueiró-Filho et al, 2004), beyond these facts can still occur the inadequate formation of enzyme involved in the detoxification of the organism, as it is the case of enzymes from glutathione, enzyme from Phase II.…”

“…Um dos desafios associados à redução do tempo de internação de pacientes em pós-parto é a implementação de um programa efetivo de cuidado domiciliar (ou de outro modelo de fácil acesso à puérpera), viabilizando a promoção de qualquer intervenção que, de outro modo, seria ofertada no interior da maternidade 4 . A pesquisa da fenilcetonúria, por exemplo, popularmente conhecida como "teste do pezinho", tem como objetivo detectar e tratar precocemente doenças que, se prevenidas, evitam sequelas como a deficiência mental 28 . Entretanto, dado que as concentrações de fenilalanina podem não estar significativamente elevadas até que o lactente tenha ingerido proteína dietética durante as primeiras 48 horas de vida, a realização desse teste não deve ocorrer precocemente 29 .…”
