摘要 目的:探讨左旋甲状腺素(L-T4)治疗对妊娠早期促甲状腺素(TSH)临界水平(2.5 mU/L≤TSH≤4.0 mU/L)合并甲状腺过氧化物酶抗体(TPOAb)阳性孕产妇母婴结局的影响,从而指导临床治疗。方法:选择2017年7月至2019年6月在福建医科大学附属泉州第一医院产检分娩的7517例单胎孕妇为研究对象,并根据妊娠早期(孕12周以内)FT4正常、TSH水平[亚临床甲状腺功能减退(TSH>4.0 mU/L)、临界水平(2.5 mU/L≤TSH≤4.0 mU/L)、正常(TSH<2.5 mU/L)]、TPOAb水平(TPOAb>50 mU/ml为阳性)及是否采用L-T4治疗分为5组:亚临床甲状腺功能减退治疗组(A组,181例)、TSH临界水平合并TPOAb阳性治疗组(B组,145例)、TSH临界水平合并TPOAb阳性未治疗组(C组,81例)、TSH临界水平合并TPOAb阴性组(D组,135例)、甲状腺功能正常组(E组,6367例)。比较各组孕产妇妊娠并发症及不良妊娠结局的发生情况。结果:5组孕妇在流产、早产、妊娠期糖尿病、妊娠期高血压疾病、羊水过少的发生率方面,差异均有统计学意义(P<0.05),在胎膜早破、羊水过多、胎盘早剥、前置胎盘、产后出血、胎儿窘迫、胎儿畸形、低出生体重儿、巨大儿、新生儿先天甲状腺功能异常及围产儿死亡的发生率方面,差异无统计学意义(P>0.05)。组间两两比较发现,C组孕妇流产、妊娠期糖尿病、妊娠期高血压疾病的发生率均高于A组、B组、D组和E组(P<0.005),且C组孕妇羊水过少的发生率高于D组,D组孕妇流产的发生率均高于A组和E组,差异均有统计学意义(P<0.005)。结论:妊娠合并亚临床甲状腺功能减退症的临床治疗需根据TSH水平、TPOAb是否阳性选择合适的方案,当TSH处于临界水平合并TPOAb阳性时,给予L-T4干预治疗可能改善部分不良妊娠结局。
