    C1q,补体系统经典途径的识别分子,在怀孕中起着核心作用。缺乏C1q的特征是滋养细胞侵入不良和妊娠失败。C1q可以是抗体应答的靶标:抗C1q自身抗体(抗C1q)存在于几种感染性和自身免疫性疾病中。在2-8%的普通人群中也检测到这些自身抗体的存在。最近的证据表明,接受辅助生殖技术(ART)的女性患先兆子痫(PE)的风险增加。特别是卵母细胞捐献(OD)怀孕。这项研究的目的是表征PE妊娠中C1q和抗C1q的水平,在健康的自发中,同源和异源ART妊娠。以下四组妇女的血清,他们被跟踪了两到三个月,被收集:PE,诊断为PE的患者;OD,卵母细胞捐赠接受者;HOM,同源ART女性;Sp,自发生理怀孕。我们的结果表明,PE患者的抗C1q水平较低。在ART孕妇中,C1q和抗C1q水平的趋势与PE患者相似,即使这些女性在怀孕期间没有出现PE样症状。这一发现表明ART妊娠中胎儿-母体界面的免疫功能障碍,通过观察来自OD的胎盘中C1q沉积证实了这一假设,相当于PE。由于与健康对照血清相比,在PE中检测到显着更低的抗C1q水平,我们假设胎盘合胞体滋养层微泡(STBM)的可能结合,在体育母亲的循环中增加。此外,抗C1q结合表位的表征表明,“生理”自身抗体主要针对C1q球形结构域。我们得出的结论是,抗C1q在怀孕中可能具有生理作用:在健康的自发怀孕期间,这些自身抗体水平的升高对于清除STBM可能很重要。在PE和病理性妊娠中(但也在OD妊娠中),合胞体滋养层细胞凋亡的增加和循环STMB水平的增加导致C1q和抗C1q的消耗。
    C1q, the recognition molecule of the classical pathway of the complement system, plays a central role in pregnancy. Lack of C1q is characterized by poor trophoblast invasion and pregnancy failure. C1q can be the target of an antibody response: anti-C1q autoantibodies (anti-C1q) are present in several infectious and autoimmune diseases. The presence of these autoantibodies has been detected also in 2-8% of the general population. Recent evidence indicates that women who undergo assisted reproductive technology (ART) have an increased risk of developing pre-eclampsia (PE), particularly oocyte donation (OD) pregnancies. The aim of this study was to characterize the levels of C1q and anti-C1q in PE gestations, in healthy spontaneous, homologous and heterologous ART pregnancies. Serum of the following four groups of women, who were followed throughout two or three trimesters, were collected: PE, patients diagnosed with PE; OD, oocyte donation recipients; HOM, homologous ART women; Sp, spontaneous physiological pregnancy. Our results indicate that PE patients have lower levels of anti-C1q. In ART pregnant women, the trend of C1q and anti-C1q levels were similar to PE patients, even though these women did not develop PE-like symptoms during pregnancy. This finding suggests an immunological dysfunction at the foetal-maternal interface in ART pregnancies, a hypothesis confirmed by the observation of C1q deposition in placentae derived from OD, comparable to PE. Since significantly lower levels of anti-C1q were detected in PE compared to healthy control sera, we hypothesize the possible binding on placental syncytiotrophoblast microvesicles (STBM), which are increased in the circulation of PE mothers. Furthermore, the characterization of the binding-epitope of anti-C1q revealed that \"physiological\" autoantibodies were mainly directed against C1q globular domain. We concluded that anti-C1q could have a physiological role in pregnancy: during the healthy spontaneous pregnancy the raised levels of these autoantibodies can be important for the clearance of STBM. In PE and in pathological pregnancies (but also in OD pregnancies), the increase in syncytiotrophoblast apoptosis and consequent increase of the circulating STMB levels lead to a consumption of C1q and anti-C1q.

    IVF cycles utilizing the ICSI technique for fertilization have been rising over the 25 years since its introduction, with indications now extending beyond male factor infertility. We have performed ICSI for 87% of cases compared with the ANZARD average of 67%. This retrospective study reports on the outcomes of 1547 autologous ART treatments undertaken over a recent 3-year period. Based on various indications, cases were managed within 3 groupings - IVF Only, ICSI Only or IVF-ICSI Split insemination where oocytes were randomly allocated. Overall 567 pregnancies arose from mostly single embryo transfer procedures up to December 2016, with 402 live births, comprising 415 infants and a low fetal abnormality rate (1.9%) was recorded. When the data was adjusted for confounders such as maternal age, measures of ovarian reserve and sperm quality, it appeared that IVF-generated and ICSI-generated embryos had a similar chance of both pregnancy and live birth. In the IVF-ICSI Split model, significantly more ICSI-generated embryos were utilised (2.5 vs 1.8; p < 0.003) with productivity rates of 67.8% for pregnancy and 43.4% for livebirths per OPU for this group. We conclude that ART clinics should apply the insemination method which will maximize embryo numbers and the first treatment for unexplained infertility should be undertaken within the IVF-ICSI Split model. Whilst ICSI-generated pregnancies are reported to have a higher rate of fetal abnormalities, our data is consistent with the view that the finding is not due to the ICSI technique per se.

    深度浸润性子宫内膜异位症是一种严重的疾病,定义为子宫内膜异位组织腹膜浸润。这种疾病可能涉及直肠阴道隔,子宫骶骨韧带,消化道或膀胱。深度浸润性子宫内膜异位症是造成疼痛和不孕的原因。这些建议的目的是回答以下问题:在深度浸润的子宫内膜异位症相关的不孕症的情况下,什么是最好的治疗策略?一线手术,然后体外受精(IVF)在持续不孕症或一线IVF的情况下,没有手术?经过详尽的文献分析,我们提出以下建议:针对深度浸润性子宫内膜异位症不孕患者的自发生育研究发现,自发妊娠率约为10%.患有子宫内膜异位症的不孕妇女希望怀孕时应考虑治疗。在没有手术的深度浸润子宫内膜异位症相关的不孕症的情况下,一线IVF是一个很好的选择。手术后(无大肠受累的深部病变)的妊娠率(自发和以下辅助生殖技术)在40%至85%之间变化。结直肠子宫内膜异位症切除术后,怀孕率从47%到59%不等。比较IVF后怀孕率的研究,无论之前是否手术,是矛盾的,不允许,到目前为止,总结试管婴儿前任何深部病变手术治疗的兴趣。在卵巢储备参数改变的情况下(年龄,AMH,窦卵泡计数),没有理由推荐一线手术或IVF。文献研究没有确定任何预后因素,允许在手术管理或IVF之间进行选择。在“深层浸润性子宫内膜异位症”的适应症中使用IVF可以使妊娠率令人满意,而没有明显的风险,关于疾病进展或卵母细胞取出程序发病率。
    Deeply infiltrating endometriosis is a severe form of the disease, defined by endometriotic tissue peritoneal infiltration. The disease may involve the rectovaginal septum, uterosacral ligaments, digestive tract or bladder. Deeply infiltrating endometriosis is responsible for disabling pain and infertility. The purpose of these recommendations is to answer the following question: in case of deeply infiltrating endometriosis associated infertility, what is the best therapeutic strategy? First-line surgery and then in vitro fertilization (IVF) in case of persistent infertility or first-line IVF, without surgery? After exhaustive literature analysis, we suggest the following recommendations: studies focusing on spontaneous fertility of infertile patients with deeply infiltrating endometriosis found spontaneous pregnancy rates about 10%. Treatment should be considered in infertile women with deeply infiltrating endometriosis when they wish to conceive. First-line IVF is a good option in case of no operated deeply infiltrating endometriosis associated infertility. Pregnancy rates (spontaneous and following assisted reproductive techniques) after surgery (deep lesions without colorectal involvement) varie from 40 to 85%. After colorectal endometriosis resection, pregnancy rates vary from 47 to 59%. The studies comparing the pregnancy rates after IVF, whether or not preceded by surgery, are contradictory and do not allow, to date, to conclude on the interest of any surgical management of deep lesions before IVF. In case of alteration of ovarian reserve parameters (age, AMH, antral follicle count), there is no argument to recommend first-line surgery or IVF. The study of the literature does not identify any prognostic factors, allowing to chose between surgical management or IVF. The use of IVF in the indication \"deep infiltrating endometriosis\" allows satisfactory pregnancy rates without significant risk, regarding disease progression or oocyte retrieval procedure morbidity.

    目的:辅助生殖技术的使用稳步增长,然而,在普通人群和不孕症患者之间仍然存在多种社会经济和人口差异。此外,与非ART同行相比,母亲和婴儿的不良结局发生率更高.
    方法:使用国际疾病分类,第九次修订(ICD-9)编码,我们在2009年对加利福尼亚州所有ART构思的分娩进行了回顾性回顾.将总共551例ART妊娠与非ART妊娠进行了比较(n=406,885)。
    结果:大多数ART分娩属于高龄(AMA)和高加索或亚洲种族的女性。几乎一半的ART分娩是多胎妊娠。与非ART交付相比,ART妊娠与前置胎盘有关,胎盘早剥,轻度先兆子痫,胎儿生长受限.
    结论:虽然无法检测所有结果,我们的研究强调了ART和非ART妊娠之间的显著种族和民族差异.
    OBJECTIVE: Use of assisted reproductive technology has increased steadily, yet multiple socioeconomic and demographic disparities remain between the general population and those with infertility. Additionally, both mothers and infants experience higher rates of adverse outcomes compared to their non-ART counterparts.
    METHODS: Using International Classification of Diseases, Ninth Revision (ICD-9) coding, we performed a retrospective review of all ART-conceived deliveries in California in 2009. A total of 551 ART pregnancies were compared to Non-ART pregnancies (n=406,885).
    RESULTS: The majority of ART deliveries belonged to women of advanced maternal age (AMA) and Caucasian or Asian race. Nearly half of all ART deliveries were multiple gestations. Compared to non-ART deliveries, ART pregnancies were associated with placenta previa, placental abruption, mild preeclampsia, and fetal growth restriction.
    CONCLUSIONS: While not powered to detect all outcomes, our study highlights significant racial and ethnic disparities between ART and Non-ART pregnancies.
