摘要: 甲状腺功能减退症是由于各种原因所致的甲状腺激素合成和分泌减少或组织利用不足,为最常见的内分泌系统疾病之一。左甲状腺素(levothyroxine, L-T4)是治疗该病的首选药物,但约10%的甲状腺功能减退症患者应用L-T4替代治疗效果不佳。影响L-T4治疗达标的因素除了年龄、合并用药、患者的依从性等外,遗传因素是另一重要因素,如Ⅱ型脱碘酶基因(type 2 deiodinase gene, DIO2)和尿苷二磷酸葡萄糖醛酸转移酶(uridine diphosphate glucuronosyltransferase, UGT)1A1基因多态性。了解基因多态性与原发性甲状腺功能减退症患者L-T4治疗剂量间的关系,可以进一步改善患者的预后,为临床用药提供参考依据。

Abstract: Hypothyroidism occurs as a result of underproduction or underutilization of thyroid hormone due to various causes. It is one of the most common endocrine disorders. Oral levothyroxine (L-T4) is the drug of choice for the management of hypothyroidism. But approximately 10% of hypothyroid patients are dissatisfied with the outcome of L-T4 replacement. Several factors can affect achieving the goals with L-T4 therapy; in addition to age, concurrent medications, patient compliance and so on, genetic factors are also important, such as the type 2 deiodinase gene (DIO2) and the uridine diphosphate glucuronosyltransferase (UGT) 1A1 gene polymorphisms. To understand the association between gene polymorphisms and L-T4 dose in patients with primary hypothyroidism will be further improved patient outcomes and provide reference for clinical use.
