2018妊娠期甲状腺过氧化物酶抗体与甲状腺功能及不良妊娠结局的关系
[摘要]目的 探讨妊娠期甲状腺过氧化物酶抗体(TPOAb)与甲状腺功能及不良妊娠结局的关系。方法 选择2016年2月~2017年4月我院收治的甲状腺激素水平正常的孕妇242例,根据TPOAb检测结果分为观察组(n=120,TPOAb阳性组)与对照组(n=122,TPOAb阴性组),追踪随访观察两组妊娠女性妊娠中晚期甲状腺功能及不良妊娠结局情况。结果 观察组患者妊娠中晚期甲状腺功能异常发生率为20.8%,显著高于对照组的7.3%,差异有统计学意义(P http://[关键词]甲状腺过氧化物酶抗体;甲状腺功能;妊娠结局

Objective To discuss the relationship between thyroid peroxidase antibody (TPOAb) and thyroid function and adverse pregnancy outcomes in pregnancy.Methods 242 pregnant women who visit at department of obstetrics and gynecology in our hospital from Feb 2016 to Apr 2017 and level of thyroid hormone was normal were divided into the observation group(n=120,TPOAb positive) and the control group(n=122, TPOAb negative) according to the results of TPOAb results.Then the thyroid function and adverse pregnancy outcomes were contrasted between the two groups.Results The incidence of thyroid dysfunction was 20.8% in the observation group,which was significantly higher than 7.3% in the control group(P0.05),具有可比性。本研究经我院医学伦理委员会批准,孕妇均知晓本研究情况并签署知情同意书。 1.2 检查方法
所有孕妇于孕12周前清晨抽空腹肘静脉血3 ml,使用3000 r/min转速,离心10 min,取上层血清检测。化学发光法测定TSH、TT4、FT4及TPOAb仪器与试剂来自美国BECKMAN COULTER公司生产。孕12周后每6周检测1次,孕28周后检测1次。检查范围:血清TT4:0~24 μg/dl,FT4:0~6 ng/dl,TSH:0~100 μIU/ml,TPOAb:0~1000 IU/ml。参考值:血清TT4:4.87~11.72 μg/dl,FT4:0.7~1.48 ng/dl,TSH:0.35~4.94 μIU/ml,TPOAb:>12 IU/ml?檠粜浴?
1.3 观察指标
对所有纳入孕妇进行登记随访,记录甲状腺功能实验室检查结果,包括血清TSH、FT4、TPOAb滴度;随访妊娠结局,包括自然流产、妊娠期高血压、早产、胎儿窘迫、胎盘早剥、有医学指征的剖宫产(如产力异常、产道异常、严重产前出血等,无法经阴道分娩,或经阴道分娩可危及孕妇及胎儿安全)、胎儿死亡等发生情况。
1.4 统计学方法
采用统计学软件SPSS 19.0分析数据,计数资料以率表示,采用χ2检验,以P参考文献]
