| 2 | Selenium supplementation in thyroid associated ophthalmopathy: an update显示文摘·The therapeutic effect of selenium(Se)has already been proven in thyroid disease and thyroid associated ophthalmopathy(TAO).In spite of clear scientific proof of its benefits in TAO,there appears to be no clear agreement among the clinicians regarding its optimum dose,duration of the treatment,efficacy and safety to date.In this review,the author summarises the findings of 135 English language articles published on this subject over the past four decades from 1973 to 2013.The regulation and metabolism of thyroid hormones require a steady supply of Se and recent studies have revealed several possible mechanisms by which Se improves the severity of thyroid disease and TAO.These mechanisms include 1)inhibitory effect of HLA-DR molecule expression on thyrocytes;2)profound reductions of thyroid stimulating hormone(TSH)receptor antibodies(TSHR-Ab)and TPO antibodies(TPO-Ab);3)prevention of dysregulation of cell-mediated immunity and B cell function;4)neutralising reactive oxygen species(ROS)and inhibition of redox control processes required for the activation,differentiation and action of lymphocytes,macrophages,neutrophils,natural killer cells involved in both acute and chronic orbital inflammation in TAO;5)inhibition of expression of proinflammatory cytokines and 6)inhibition of prostaglandin and leukotriene synthesis.An increased oxidative stress has been observed in both acute and chronic phases of thyroid disease with raised tissue concentrations of ROS.The benefits of Se supplementation in individuals with TAO appear to be proportionate to the degree of systemic activity of the thyroid disease.The maximal benefit of Se supplementation is therefore seen in thesubjects who are hyperthyroid.Restoration of euthyroidism is one of the main goals in the management of TAO and when anti-thyroid drugs are combined with Se,the patients with Graves'disease(GD)and autoimmune thyroiditis(AIT)achieved euthyroidism faster than those treated with anti-thyroid drugs alone.Se status of normal adult humans can vary widely and Se supplementation may confer benefit only if serum Se levels are insufficient.The author recommends that serum Se levels of patients with TAO to be assessed prior to and during Se supplementation at regular intervals to avoid potential iatrogenic chronic Se overdose. | Aruna Dharmasena | 2014 | International Journal of Ophthalmology(English edition)2014,7,2: | 5 |
