摘要: 目的 探讨妊娠甲状腺功能减退症(甲减)妊娠期间左旋甲状腺素钠替代剂量。方法 2014年3月至
2015年3月入选在我院分娩的274例妊娠合并甲减孕妇,其中亚临床型甲减组(SHT)207例,临床型甲减组(HT)67
例,以妊娠早期促甲状腺激素(TSH)<2.5mU/L,妊娠中晚期TSH<3.0mU/L为治疗目标,根据TSH 及孕周变化
予调整左旋甲状腺素钠治疗剂量。并根据TSH 水平分为TSH1 组,TSH3~5mU/L,TSH2 组,TSH5~8mU/L,
TSH3 组,TSH8~10mU/L,TSH4 组,TSH10~15mU/L,TSH5 组,TSH15~20 mU/L 和TSH6 组,TSH>20
mU/L。结果 各组达治疗目标后,SHT 组T1、T2 和T3 期,左旋甲状腺素钠剂量分别为:(52.26±19.43)μg、
(56.69±20.58)μg和(56.76±19.99)μg;HT组在T1、T2 和T3 期,左旋甲状腺素钠剂量分别为:(64.58±50.26)
μg、(66.67±47.64)μg和(65.91±34.06)μg;TSH1 组-TSH6 组左旋甲状腺素钠剂量分别为(45.65±16.08)μg、
(72.32±14.85)μg、(75.00±13.06)μg、(112.5±53.03)μg、(137.5±23.18)μg和(150.00±23.13)μg;T1、T2 和
T3 妊娠期TSH2、TSH3、TSH4 和TSH5 组左旋甲状腺素钠剂量高于TSH1 组(P <0.05);TSH4、TSH5 和TSH6 组
左旋甲状腺素钠片剂量高于TSH2 组(P <0.05);TSH4、TSH5 和TSH6 组高于TSH3 组(P <0.05);TSH5 和
TSH6 组高于TSH4 组(P <0.05);TSH6 组高于TSH5 组(P <0.05)。结论 妊娠期临床型甲减左旋甲状腺素钠
剂量在T1、T2 和T3 妊娠期均高于亚临床型甲减(P <0.05)。随着TSH 水平增高,所需左旋甲状腺素钠明显增加
(P <0.05)。

Abstract:

ObjectiveTo explore the levothyroxine dose in patients with hypothyroidism during pregnancy. MethodsA total of 274 pregnant subjects with hypothyroidism including 207 patients with subclinical hypothyroidism (SHT) and 67 patients with clinical hypothyroidism (HT) were enrolled in this study from March 2014 to March 2015. According to thyrotrophic (TSH) levels, the levothyroxine dose was adjusted to reach the targets with the first trimester TSH ranging 0.12.5 mU/L, the second trimester(T2) TSH ranging 0.23.0 mU/L and the third trimester(T3) TSH ranging 0.33.0 mU/L. The subjects were divided into different groups on the basis of TSH levels, including TSH1 group: TSH 35 mU/L, TSH2 group: TSH 58 mU/L, TSH3 group: TSH 810 mU/L, TSH4 group: TSH 1015 mU/L, TSH5 group: TSH 1520 mU/L and TSH6 group: TSH>20 mU/L. ResultsThe levothyroxine doses were respectively (52.26±19.43) μg in T1 period,( 56.69±20.58) μg in T2 period and  (56.76±19.99) μg in T3 period in subclinical hypothyroidism, and respectively   (64.58±50.26) μg in T1 period,(66.67±47.64) μg in T2 period and (65.91±34.06) μg in T3 period in clinical hypothyroidism. The doses of levothyroxine were (45.65±16.08) μg,(72.32±14.85) μg, (75.00±13.06) μg, (112.5±53.03) μg,(137.5±23.18) μg and  (150.00±23.13) μg from TSH1 group to TSH6 group, respectively. The doses of levothyroxine in TSH2, TSH3, TSH4 and TSH5 groups were significantly higher than that of TSH1 group during T1 to T3 trimester (P<0.05). The doses of levothyroxine in TSH4, TSH5 and TSH6 groups were significantly higher than that of TSH2 group (P<0.05). The doses of levothyroxine in TSH4, TSH5 and TSH6 groups higher than TSH3 group (P<0.05); The doses of levothyroxine in TSH5 and TSH6 groups were significantly higher than that of TSH4 group (P<0.05). The dose of levothyroxine in TSH6 group were significantly higher than that of TSH5 group (P<0.05). ConclusionThe levothyroxine (LT4) dose in clinical hypothyroidism in T1, T2 and T3 trimester were significantly higher than those in subclinical hypothyroidism (P<0.05). The dose of levothyroxine sodium increased significantly accompanied by the increased TSH level during pregnancy (P<0.05).
