[摘要] 目的 探讨甲状腺抗体阳性对复发性流产的影响。 方法 整群选取在2011年5月—2014年5月期间该院收治的有自然流产史但处于非孕期的妇女103例为观察组,在同一时间段内选取有正常分娩史的非孕期妇女97例为对照组,用化学发光法检测两组妇女血清中甲状腺球蛋白抗体(TgAb)和甲状腺过氧化物酶抗体(TPOAb),研究甲状腺抗体阳性对复发性流产的影响。 结果 观察组妇女血清中甲状腺自身抗体(TA)总阳性率21.36%、TgAb阳性率15.53%和TPOAb阳性率17.48%均高于对照组10.31%、5.15%、6.19%,差异有统计学意义(P<0.05)。观察组妇女血清中TgAb定量值(1.34±0.39)稍高于对照组(1.28±0.27),差异无统计学意义(P>0.05);而观察组妇女血清中TPOAb定量值(0.94±0.41)高于对照组(0.73±0.26),差异有统计学意义(P<0.05)。TA阳性、TgAb阳性和TPOAb阳性3个变量中,仅有TPOAb阳性保留到最后,且观察组妇女TPOAb阳性比例是对照组的3.51倍。结论 甲状腺抗体与复发性流产之间具有相关性,复发性自然流产妇女的甲状腺抗体阳性率增高,在临床上值得借鉴,对预防和治疗复发性流产的发生有重要意义。

[Abstract] Objective To investigate the effect of positive thyroid antibody on recurrent spontaneous abortion. Methods 103 non-pregnant women with the history of spontaneous abortion and 97 non-pregnant women with the history of normal delivery admitted in our hospital from May 2011 to May 2014 were selected as the observation group and the control group, respectively. Chemiluminescence method was used to test the thyroglobulin antibody(TgAb) and thyroid peroxidase antibody(TPOAb) in both groups. And the effect of positive thyroid antibody on recurrent spontaneous abortion was studied. Results Compared with the control group, the observation group had much higher total positive rate of serum thyroid autoantibody(TA)(21.36% vs 10.31%), obviously higher positive rate of serum TgAb(15.53% vs 5.15%), significantly higher positive rate of serum TPOAb (17.48% vs 6.19%) (P<0.05). The serum quantitative value of TgAb was slightly higher in the observation group than that in the control group[(1.34±0.39) vs (1.28±0.27)] (P>0.05). The serum quantitative value of TPOAb was much higher in the observation group than that in the control group[(0.94±0.41) vs (0.73±0.26)] (P<0.05). The three variables, positive TA, positive TgAb and positive TPOAb, only positive TPOAb until the end, and the TPOAb positive ratio in the observation group was 3.51 times higher than that in the control group. Conclusion Thyroid antibody has correlation with recurrent spontaneous abortion. The positive rate of thyroid antibody increases significantly in women with recurrent spontaneous abortion, which is worthy of clinical reference in the prevention and treatment of recurrent spontaneous abortion.

流产是指妊娠终止于28周前,胎儿体重小于1 kg;近年来,国际上将自然流产连续发生两次或两次以上称为复发性流产(RSA)。复发性流产是妊娠期妇女易出现的疾病,据统计,妊娠妇女中约有5%出现两次或两次以上的自然流产,而约有1~2%出现三次或三次以上[1]。复发性流产的病因有很多,主要有染色体异常、子宫解剖结构异常、自身免疫因素、内分泌异常等,其中最主要的原因是自身免疫异常,约占20%左右,自身免疫因素主要是自身的抗体。有相关研究显示,甲状腺抗体与复发性流产有一定的关系,但目前国内对此方面的报道还不多[2],为了进一步研究甲状腺抗体与复发性流产的关系,故该研究整群选取在2011年5月—2014年5月期间该院收治的有自然流产史但处于非孕……
