自身免疫异常对不明原因性不孕女性IVF妊娠结局的影响

目的:探讨自身免疫异常对不明原因性不孕女性IVF妊娠结局的影响。方法:选择2002年1月～2006年7月由于不明原因性不孕而接受IVF-ET治疗的女性236例,其中血清抗磷脂抗体(APA)阳性者34例,抗滋养细胞膜抗体(ATA)阳性者33例,hCG抗体(hCGAb)阳性者35例,抗子宫内膜抗体(EmAb)阳性者32例,阴性对照102例,两种或两种以上抗体阳性患者排除本研究之外。比较抗体阳性组和阴性对照组女性胚胎种植率、临床妊娠率、流产率、生化妊娠率及持续妊娠率。结果:各抗体阳性组虽较阴性对照组的临床妊娠率、胚胎种植率低,但差异无显著性(P>0.05);APA、ATA、hCGAb阳性组生化妊娠率高于EmAb阳性组及阴性对照组(P<0.05);EmAb阳性组与阴性对照组之间生化妊娠率差异无显著性(P>0.05);各抗体阳性组流产率均高于阴性对照组(P<0.05);持续妊娠率均低于阴性对照组(P<0.05)。结论:APA、ATA、hCGAb、EmAb的存在会引起不明原因IVF妊娠流产率增高,从而降低了持续妊娠率,有必要对此类患者进行自身抗体的检测。

Autoimmune Disorders Affect the in vitro Fertilization Outcome in Infertile Women

OBJECTIVE: To analyze the effect of autoimmune disorders on the outcome of in vitro fertilization and embryo transfer (IVF-ET) in infertile women. METHODS: A total of 236 infertile women underwent IVF-ET, including 34 with antiphosphoipid antibody (APA) positive, 33 anti-trophoblast antibody (ATA) positive, 35 anti-hCG antibody (hCGAb) positive, 32 anti-endometrium antibody (EmAb) positive, and 102 with antibodies negative that comprised the control group. Those with two or more antibodies positive were excluded in this study. Comparisons were made in the rates of embryo implantation, clinical pregnancy, miscarriage and biochemical pregnancy between the positive groups and the negative controls. RESULTS: There were no significant differences in the rates of embryo implantation and clinical pregnancy between the positive and negative groups (P > 0.05). The rate of biochemical pregnancy was higher in the APA, ATA and hCGAb positive than in the EmAb positive and the control group (P < 0.05). The miscarriage rate was higher while the ongoing pregnancy rate was lower in the positive groups than in the negative control (P < 0.05). CONCLUSION: Such autoantibodies as APA, ATA, HCG-Ab and EmAb may cause miscarriage in infertile women undergoing IVF and consequently reduce the rate of ongoing pregnancy, which necessitates the determination of these antibodies in these patients.
