摘要
目的:探讨Graves’甲亢对妊娠结局的影响。方法:选取Graves’甲亢孕妇95例,其中37例入组时甲状腺功能控制良好(控制组),58例入组时甲状腺功能控制不佳(未控制组);根据入组时是否使用抗甲状腺药物(ATDs)再分成用ATDs与未用ATDs亚组。选取同期正常妊娠产妇125例作为正常对照组。分析各组孕期甲状腺功能和促甲状腺激素受体抗体(TRAb)水平变化及其对妊娠结局的影响。结果:控制组中孕期甲功持续缓解占24.32%(9/37),缓解及甲功完全正常的比例为37.84%(14/37)和16.22%(6/37),有8.11%的孕妇甲亢复发。未控制组62.07%的孕妇孕期持续甲亢,甲功缓解及完全正常分别有18.97%(11/58)和15.51%(9/58)。未控制组TRAb水平在孕早、中、晚期及产后均显著高于控制组(P<0.05);两组孕早期TRAb均显著高于孕中期(P<0.05)。未控制组妊娠高血压、子痫前期、低出生体重、产后出血及新生儿甲减的发生率显著高于控制组及对照组(P<0.05),控制组与对照组比较差异无统计学意义(P>0.05)。结论:Graves’甲亢对妊娠结局产生不良影响。孕期甲亢控制不佳增加母婴不良结局的发生。合理使用抗甲状腺药物可稳定甲功和TRAb,但由于其可通过胎盘,可能导致胎儿或新生儿甲减的发生,仍需谨慎使用。
