Apresentação pediátrica da doença de Fabry: sintomas comuns levando ao diagnóstico de uma doença rara
Conteúdo do artigo principal
Resumo
A doença de Fabry (DF) é uma doença de origem genética ligada ao cromossomo x. Ocorre devido a um erro inato no metabolismo dos glicoesfigolipídeos (GSL), decorrente da deficiência da enzima alfa-galactosidase A (alfa-Gal), cursando com acúmulo de globotriasilceramida (Gb3). A deficiência dessa enzima ocasiona um acúmulo progressivo de Gb3 dentro do lisossomo, originando complicações em diferentes órgãos e sistemas corporais. Esse armazenamento explica a ocorrência dos primeiros sintomas durante a infância, caracterizados por dor, sensibilidade ao calor e ao frio, doença gastrointestinal, enfatizando a dor abdominal recorrente e a diarreia. Relatamos um caso da DF em uma criança do sexo masculino e ressaltamos a importância dos sinais clínicos e sintomas que conduzem o pediatra ao diagnóstico da doença durante a primeira infância.
