目的:探讨妊娠合并甲状腺功能亢进对妊娠结局的影响及二者之间的相互关系。方法:对被诊断为妊娠合并甲亢患者78例根据是否对病情进行干预分疾病控制组40例和未控制组38例,同期选取40例无任何妊娠合并症的孕妇作为对照组。根据测定3组血清中甲状腺功能的三项指标TSH、FT3、FT4和β2-m值探讨甲状腺功能亢进对妊娠的影响及相互间可能存在的关系。结果:未控制组血清中TSH、FT3、FT4与疾病控制组比较差异有统计学意义(P<0.01),FT3、FT4、β2-m测定值与对照组差异有统计学意义(P<0.01);而疾病控制组血清FT3、FT4、β2-m测定值与对照组差异无统计学意义(P>0.05)。未控制组引产、早产、流产及相关妊娠期并发症的发生率高于疾病控制组,差异有统计学意义(P<0.05)。结论:甲状腺功能亢进增加了妊娠并发症的发病率,因此对于妊娠期妇女应监测甲状腺激素水平,从而减少不良妊娠结局的发生。
Objective: To investigate the impact of pregnancy complicated with hyperthyroidism on pregnancy outcome and the relationship between the two. Methods: 78 patients diagnosed with pregnancy complicated with hyperthyroidism were divided into control group (40 cases) and uncontrolled group (38 cases). Forty pregnant women without any pregnancy complications were selected as the control group. According to the determination of TSH, FT3, FT4 and β2-m of thyroid function in three groups of serum, we investigated the effect of hyperthyroidism on pregnancy and the possible relationship between them. Results: The levels of TSH, FT3 and FT4 in the uncontrolled group were significantly different from those in the control group (P <0.01), and there was significant difference between the measured values of FT3, FT4 and β2-m in the control group (P <0.01) ; While the disease control group serum FT3, FT4, β2-m measured values and the control group no significant difference (P> 0.05). The incidence of miscarriage, premature labor, abortion and related pregnancy complications in uncontrolled group was higher than that in disease control group (P <0.05). CONCLUSIONS: Hyperthyroidism increases the incidence of pregnancy complications and therefore thyroid hormone levels should be monitored in pregnant women to reduce the incidence of adverse pregnancy outcomes.
