定义
硒缺乏是罕见的，但已观察到个人长期全肠外营养缺乏硒。由这种情况引起的缺乏症的临床表现是罕见的，而且定义不清。其中包括肌无力和肌痛，在一些情况下，发展为充血性心力衰竭。硒对甲状腺激素代谢的重要性从T3–T4比率的变化中可以明显看出，在婴儿和老年受试者中，相对轻微的硒缺乏会导致T3–T4比率的变化。
Selenium deficiency is rare but has been observed in individuals on long-term total parenteral nutrition lacking selenium. Clinical manifestations of deficiency arising from such situations are uncommon and poorly defined. They include muscular weakness and myalgia with, in several instances, the development of congestive heart failure. The importance of selenium for thyroid hormone metabolism is evident from changes in the T3–T4 ratio which develop after relatively mild selenium depletion in infants and elderly subjects.
