摘要 目的探讨妊娠晚期新发甲状腺功能减退(甲减)患者血清生化指标变化及与不良妊娠结局的关系.方法选择2016-2018年在重庆市渝北区人民医院系统产前检查的孕妇资料1120例作为研究对象,建立本地区妊娠期甲状腺功能参考值范围并探索研究妊娠晚期新发甲减患者血清生化指标变化及与不良妊娠结局的关系.结果确立本地区妊娠晚期甲减的诊断标准,具体如下:①临床甲减为血清促甲状腺激素(TSH)>6.83 mIU/L,血清游离甲状腺激素(FT4)<8.51 pmol/L.另外当TSH≥10 mIU/L时,无论FT4是否改变,均可诊断临床甲减;②亚临床甲减为8.51 pmol/L<FT4<14.71 pmol/L,6.83 mIU/L<TSH<10 mIU/L;③低甲状腺素(T4)血症为FT4<9.35 pmol/L,0.82 mIU/L<TSH<6.83 mIU/L.采用相关课题组提供妊娠参考值,受试孕妇中共发现新发甲减者109例,占10.90%,临床甲减9例,占0.90%,亚临床甲减37例,占3.70%,低T4血症63例,占6.30%;采用本次研究所得妊娠参考值,受试孕妇中共发现新发甲减者113例,占11.30%,临床减10例,占1.00%,亚临床甲减39例,占3.90%,低T4血症64例,占6.40%.两种方法比较,差异无统计学意义(X^2=0.61,P=0.43).在113例妊娠晚期新发甲减患者中,共有97例患者的尿碘水平<150μg/L,尿碘水平≥150μg/L者仅占16例,差异有统计学意义(X^2=4.21,P=0.032).与对照组相比,新发甲减组的胆固醇、糖化血红蛋白、三酰甘油、肌酐、尿素、尿酸均明显高于前者,差异有统计学意义(X^2=11.63,P=0.000;X^2=18.99,P=0.000;X^2=36.23,P=0.000;X^2=36.19,P=0.000;X^2=62.26,P=0.000;X^2=71.50,P=0.000).新发甲减组的早产、低出生体质量儿、胎膜早破、臀位、胎儿窘迫、妊娠期糖尿病,子痫前期发生率均明显高于对照组,差异有统计学意义(X^2=15.73,P=0.000;X^2=4.31,P=0.037;X^2=9.01,P=0.002;X^2=9.20,P=0.002;X^2=7.85,P=0.005;X^2=15.40,P=0.000;X^2=9.20,P=0.002).结论妊娠晚期合并新发甲减与不良妊娠结局有着密切关系,需要及时建立本地区妊娠期甲状腺功能参考值范围,筛查患病人群,提高诊断率,给予合理治疗方案,改善妊娠结局.
