Deficiência de selênio é rara mas tem sido observada em indivíduos em uso prolongado de dieta parenteral total(NPT) sem selênio. Manifestações clínicas da deficiência decorrente de tal situação são incomuns e pouco definidas. Elas incluem fraqueza muscular e mialgia com, em casos graves, o desenvolvimento de insuficiência cardíaca congestiva. A importância do selênio para o metabolismo dos hormônios tireoidianos é evidente, a partir de mudanças na proporção T3-T4 que se desenvolvem após uma depleção de selênio relativamente leve em bebês e idosos | |||
