IVF/ICSI治疗后早期自然流产的相关因素分析

目的探讨不孕症患者接受体外受精/卵细胞质内单精子注射(IVF/ICSI)-胚胎移植治疗获得妊娠后发生早期流产的相关因素。方法回顾性分析笔者医院生殖中心2008年6月～2009年12月间经IVF/ICSI治疗获得临床妊娠的331例患者,按妊娠结局分为早期流产组及继续妊娠组;分析受精方式、年龄、既往自然流产史、移植后12天血β-HCG值、孕囊数及不孕原因与早期流产率的关系。结果 IVF、ICSI两种受精方式的早期流产率无显著差异,早期流产组的年龄显著高于继续妊娠组,多胎妊娠率、移植后12天血β-HCG值显著低于继续妊娠组。众多导致不孕的病因中,排卵障碍的流产率最高,差异具有统计学意义。结论高龄、单胎妊娠、多囊卵巢为IVF/ICSI治疗后早期自然流产的危险因素,移植后12天低β-HCG水平可高度预测早期自然流产的发生。     

Patients with cervical <Emphasis Type="Italic">Ureaplasma Urealyticum</Emphasis> and <Emphasis Type="Italic">Chlamydia Trachomatis</Emphasis> infection undergoing IVF/ICSI-ET: The need for new paradigm

Genital tract infections with ureaplasma urealyticum (UU) and chlamydia trachomatis (CT) are the most frequent sexually-transmitted disease worldwide. UU and CT infections are considered to be the leading cause for infertility and adverse pregnancy outcomes. However, little is known about the specific effect of cervical UU and CT infections on the etiology of female infertility, as well as the pregnancy outcomes of the patients undergoing in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET). In order to find the association between cervical UU and/or CT infection and pregnancy outcomes, we conducted a retrospective case-control study on the patients undergoing IVF/ICSI-ET with cervical UU and/or CT infection. A total of 2208 patients who received IVF/ICSI-ET were enrolled in this study. Data on the general conditions, pregnancy history and clinical pregnant outcomes were analyzed in terms of the cervical UU and CT detection. Our results revealed that cervical UU and CT infections were the risk factors for ectopic pregnancy and tubal factor-induced infertility. Moreover, the pregnancy rate, abortion rate, ectopic pregnancy rate and premature birth rate in patients with UU and/or CT infections showed no significant difference when compared with the control group. We recommend that cervical UU and CT detection should be an optional item for infertility patients and clinical UU detection should differentiate the subtypes of cervical UU. Positive cervical UU and CT infections should not be taken as strict contraindications for IVF/ICSI-ET.

白细胞介素-17对小鼠胚胎丢失的作用

目的:探讨正常妊娠与自然流产小鼠体内Th17/Treg细胞的表达差异以及白细胞介素-17(IL-17)对正常妊娠小鼠胚胎丢失的影响。方法:孕4 d时分别给予正常妊娠小鼠(CBA/J♀×BALB/c♂)生理盐水和IL-17A构建正常妊娠组和给药组,给予自然流产小鼠(CBA/J♀×DBA/2♂)生理盐水构建自然流产组。孕14 d时计算胚胎吸收率,采用ELISA法测定外周血IL-17水平,Real-time PCR及Western blot法检测胎盘组织IL-17、RORγt及Foxp3的表达水平。结果:自然流产组及给药组胚胎吸收率、胎盘组织中IL-17、RORγt的mRNA及蛋白水平显著高于正常妊娠组,而Foxp3水平则低于正常妊娠组;自然流产组外周血IL-17含量显著高于正常妊娠组。结论:自然流产小鼠体内Th17/Treg平衡明显向Th17细胞偏移,IL-17是介导流产发生的独立危险因素之一。
