recurrent miscarriage

复发性流产
  • 文章类型: Case Reports
    低雄激素血症通常不被认为是复发性流产的潜在原因。我们介绍了一名30岁女性的案例,该女性先前有6次怀孕,导致1次活产和5次怀孕失败。包括妊娠24周的胎儿死亡。她在第四次失利后接受了标准调查,在专门的流产诊所.狼疮抗凝剂,抗心磷脂抗体,甲状腺功能,亲本核型均正常。在妊娠16周时,胎儿产品证实了她第四次流产的三倍体。她放心,建议再次怀孕,但在妊娠24周后胎儿死亡。这是她第五次怀孕,没有任何解释。她于2022年1月参加了我们的恢复性生殖医学(RRM)诊所。除了卵泡功能差,我们第一次发现了低雄激素血症.治疗包括用克罗米芬和DHEA25mg每天两次刺激卵泡,在整个怀孕期间维持DHEA20mg每天一次。她在2023年11月妊娠36周时通过剖宫产分娩了一个健康的男婴。低雄激素血症应被视为复发性流产或妊娠晚期流产的妇女的促成因素。口服DHEA将雄激素恢复到正常水平是安全的,可以改善妊娠结局。
    Hypoandrogenemia is not usually considered as a potential cause of recurrent miscarriage. We present the case of a 30-year-old female with 6 previous pregnancies resulting in one live birth and 5 pregnancy losses, including fetal demise at 24 weeks gestation. She had standard investigations after her 4th loss, at a specialized miscarriage clinic. Lupus anticoagulant, anticardiolipin antibodies, thyroid function, parental karyotypes were all normal. Fetal products confirmed triploidy for her 4th miscarriage at 16 weeks gestation. She was reassured and advised to conceive again but had fetal demise after 24 weeks gestation. This was her 5th pregnancy loss with no explanation. She attended our Restorative Reproductive Medicine (RRM) clinic in January 2022. In addition to poor follicle function, we found hypoandrogenemia for the first time. Treatment included follicle stimulation with clomiphene and DHEA 25 mg twice daily pre-conception with DHEA 20 mg once daily maintained throughout pregnancy. She delivered a healthy baby boy by cesarean section at 36 weeks gestation in November 2023. Hypoandrogenemia should be considered as a contributory factor for women with recurrent miscarriage or late pregnancy loss. Restoration of androgens to normal levels with oral DHEA is safe and can improve pregnancy outcome.

    背景:最近的研究将复发性妊娠丢失(RPL)与精子基因组异常联系起来,特别是在无精子症因子(AZF)区域的微缺失。这项研究调查了伊朗夫妇中AZF区域Y染色体微缺失与RPL之间的潜在关联。
    方法:该研究对240名男性进行了病例对照研究:120名男性的伴侣经历了复发性流产,和120名没有流产史的成功怀孕者。这项研究使用了精液参数,激素分析,并通过多重PCR和YChromStrip试剂盒进行微缺失分析。因此,AZFa的序列标记位点(STS)标记(sY84,sY86),AZFb(sY127,sY134),和AZFc(sY254,sY255)区域被检查。
    结果:病例和对照组之间精液参数和性激素水平的变化表明,伴侣反复流产的男性睾丸功能受损(p<0.05)。此外,研究显示精子数量与卵泡刺激素(FSH)水平呈负相关,精子活力和睾酮浓度呈阳性。对照组没有微缺失,而RPL组AZFb(sY134)缺失20例(16.66%),AZFb(sY127)(8.33%)和AZFc(sY254)(8.33%)各10例。
    结论:sY134(AZFb)微缺失与伊朗男性RPL显著相关(p=0.03)。RPL夫妇的AZF微缺失筛查可以为种族遗传咨询和复发性流产的管理提供有价值的信息。对更多人口或不同种族群体的进一步研究,结论和其他因素如表观遗传变化解释了AZF微缺失在RPL中的作用。
    BACKGROUND: Recent studies have linked recurrent pregnancy loss (RPL) to abnormalities in the sperm genome, specifically microdeletions in the azoospermia factor (AZF) region. This study investigated the potential association between Y chromosome microdeletions in the AZF region and RPL in Iranian couples.
    METHODS: The research presents a case-control study of 240 men: 120 whose partners experienced recurrent miscarriage, and 120 who had successful pregnancies without history of miscarriage. The study used semen parameters, hormone analyses, and microdeletion analysis via multiplex PCR and the YChromStrip kit. Thus, the sequence-tagged site (STS) markers of AZFa (sY84, sY86), AZFb (sY127, sY134), and AZFc (sY254, sY255) regions were examined.
    RESULTS: The variations in semen parameters and sex hormone levels between cases and controls are suggest impaired testicular function in men whose partners had recurrent miscarriages (p < 0.05). Furthermore, the study revealed a negative correlation between sperm count and follicle-stimulating hormone (FSH) level, and a positive one between sperm motility and testosterone concentration. There were no microdeletions in the control group, while the RPL group showed 20 deletions in AZFb (sY134) (16.66%) and 10 deletions each in AZFb (sY127) (8.33%) and AZFc (sY254) (8.33%).
    CONCLUSIONS: Microdeletions in sY134 (AZFb) were significantly associated with RPL in Iranian men (p = 0.03). AZF microdeletion screening in couples with RPL can provide valuable information for ethnical genetic counseling and management of recurrent miscarriage. Further studies on larger populations or across various ethnic groups, conclusions and the inclusion of other factors like epigenetic changes explain the role of AZF microdeletions in RPL.

    结论:与对照组相比,原因不明的复发性妊娠流产妇女的血管健康受损。这种受损的动脉血管健康可以通过运动来改善。
    OBJECTIVE: To investigate whether women with unexplained recurrent pregnancy loss have impaired arterial vascular health compared with controls, and to evaluate whether this is modifiable by exercise.
    METHODS: Experimental case-control pilot study.
    METHODS: University medical centre in the Netherlands.
    METHODS: Twelve women with unexplained recurrent pregnancy loss, 11 nulliparous women and 19 primiparous women with a history of uncomplicated pregnancies.
    METHODS: In all three groups we measured baseline characteristics, metabolic components and arterial vascular health, and repeated this in women with unexplained recurrent pregnancy loss after 1 month of protocolled and supervised cycle training.
    METHODS: Differences in arterial vascular health between women with unexplained recurrent pregnancy loss and controls, and the effect of exercise on arterial vascular health in women with unexplained recurrent pregnancy loss.
    RESULTS: Women with unexplained recurrent pregnancy loss have a significantly increased carotid intima media thickness in comparison with both controls (both P < 0.01), a significantly decreased brachial endothelial dependent flow-mediated vasodilation in comparison with both controls (nulliparous: P < 0.01; primiparous: P = 0.05) and a significantly decreased femoral endothelial dependent flow-mediated vasodilation in comparison with primiparous women (P = 0.01). The endothelium independent glyceryl trinitrate response was similar in all groups. With 1 month of exercise, the carotid intima media thickness decreased significantly by 7% (P = 0.05) and the femoral FMD increased significantly by 10% (P = 0.01) in women with unexplained recurrent pregnancy loss.
    CONCLUSIONS: Women with unexplained recurrent pregnancy loss have an impaired vascular health in comparison with controls. This impaired arterial vascular health can be improved by exercise.

    复发性流产(RM),定义为妊娠20周前两次或两次以上连续流产的特点是多因素病因。在育龄妇女中,RM的患病率从0.8%到13.5%不等。RM的病因学基础可以追溯到染色体,解剖,激素和免疫因素,而一半的病例仍然是特发性的。
    本研究旨在调查印度人群中白介素-10(IL-10)多态性与RM的关联。
    本研究包括总共414名个体,包括有两次或两次以上妊娠流产的RM妇女(n=199)和没有任何妊娠流产史的健康妇女(n=215)作为对照组。
    研究了RM女性和健康女性的人口统计学特征和生殖史。使用聚合酶链反应(PCR)限制性片段长度多态性和扩增突变难治性系统PCR对IL-10多态性rs1800872和rs1800896进行基因型分析,分别。
    学生t检验用于比较两组之间的人口统计学特征和生殖史。皮尔逊卡方用于计算哈代-温伯格均衡,等位基因和基因型频率。所有统计分析均使用SPSS(21版,IBMSPSS,NY,美国)。
    我们的结果表明,rs1800872多态性的基因型和等位基因频率在RM病例和对照女性之间没有显着差异(分别为P=0.07和P=0.23)。rs1800896的GG基因型(P=0.007)和G等位基因(P=0.003)与RM的风险增加显着相关。对于rs1800896,两组之间的遗传模型(显性和共显性模型)分布也存在统计学上的显着差异。然而,单倍型分析显示,没有单倍型提供RM进展的风险。
    该研究是我们地区的同类研究中的第一项,并提供了有关RM遗传学的基线数据。
    UNASSIGNED: Recurrent miscarriage (RM), defined as two or more consecutive miscarriages prior to the 20th week of gestation is characterised by multifactorial aetiology. The prevalence of RM varies from 0.8% to 13.5% amongst women of reproductive age. The aetiological basis of RM has been traced to chromosomal, anatomic, hormonal and immunologic factors while half of the cases remain idiopathic.
    UNASSIGNED: This study aimed to investigate the association of interleukin-10 (IL-10) polymorphisms with RM amongst the Indian population.
    UNASSIGNED: The present study included a total of 414 individuals including RM women (n = 199) with two or more pregnancy losses and healthy women (n = 215) without any previous history of pregnancy loss were taken as the control group.
    UNASSIGNED: Demographic features and reproductive history of women with RM and healthy women were taken. Genotype analysis of IL-10 polymorphisms rs1800872 and rs1800896 was performed using the polymerase chain reaction (PCR) restriction fragment length polymorphism and amplification mutation refractory system PCR, respectively.
    UNASSIGNED: Student\'s t-test was used to compare the demographic features and reproductive history amongst both groups. Pearson\'s Chi-square was used to calculate the Hardy-Weinberg equilibrium, allelic and genotypic frequencies. All the statistical analyses were performed using the SPSS (version 21, IBM SPSS, NY, USA).
    UNASSIGNED: Our results suggested that the genotypic and allelic frequency of rs1800872 polymorphism did not differ significantly between RM cases and control women (P = 0.07 and P = 0.23, respectively). The GG genotype (P = 0.007) and G allele (P = 0.003) of rs1800896 were significantly associated with an increased risk of RM. A statistically significant difference was also found for the distribution of genetic models (dominant and co-dominant model) between both groups for rs1800896. However, haplotype analysis revealed that none of the haplotypes provides a risk for the progression of RM.
    UNASSIGNED: The study is the first of its kind from our region and provides baseline data on the genetics of RM.

    背景:因子V缺乏症是一种罕见的先天性或获得性出血性疾病。因子V缺乏主要表现为粘膜出血。在正常妊娠期间,凝血因子V不会显着增加。因为怀孕会受到凝血障碍的威胁,凝血因子水平的异常变化会给孕妇带来挑战。
    方法:我们报告了一名40岁的孕妇,在怀孕28周时出现长期牙龈出血和鼻出血。她过去的病史包括两次原因不明的堕胎。体格检查并不明显,但血液检查显示PT和PTT升高,因子V活性显著下降,其他因素均在正常范围内。随后,患者被诊断为先天性因子V缺乏症。用新鲜冷冻血浆处理后,她接受了阴道分娩,出生了一个因子V缺乏症的婴儿。
    结论:这是关于先天性因子V缺乏症患者复发性流产的第二次报告。即使没有任何症状的患者,临床医生也应考虑有特发性流产史的女性因子V缺乏的可能性。
    BACKGROUND: Factor V deficiency is a rare bleeding disorder that can be either congenital or acquired. Factor V deficiency mostly present with mucosal bleeding. Coagulation factor V does not increase considerably during normal gestation. Since pregnancy can be threatened by blood clotting disorders, abnormal changes in coagulation factors level can pose challenges to pregnant women.
    METHODS: We report a 40-year-old pregnant woman with prolonged gingival bleeding and epistaxis at 28 weeks of pregnancy. Her past medical history included two unexplained abortions. Physical examination was unremarkable, but the blood test showed elevated PT and PTT with a considerable decrease in factor V activity, while other factors were within normal range. Subsequently, the patient was diagnosed with congenital factor V deficiency. After treatment with fresh frozen plasma, she underwent vaginal delivery and a baby with factor V deficiency was born.
    CONCLUSIONS: This is the second report of recurrent miscarriage in congenital factor V deficiency patients. Clinicians should consider the possibility of factor V deficiency in women with a history of idiopathic miscarriage even in patients without any symptoms.

    目的:子宫内膜或阴道菌群的组成与复发性妊娠丢失(RPL)有关吗?
    方法:收集了47名连续两次或两次以上妊娠丢失的妇女和39名没有妊娠丢失史的健康对照妇女的子宫内膜和阴道样本,2018年3月至2020年12月在赫尔辛基大学医院,赫尔辛基,芬兰。子宫内膜和阴道微生物群的组成,使用16SrRNA基因扩增子测序分析,在RPL和对照女性之间进行了比较,在个别阴道和子宫内膜样本之间。使用内部转录的间隔区1扩增子测序来分析分枝杆菌群组合物,以进行描述性总结。这些模型根据体重指数进行了调整,年龄和平价。错误发现率校正的P值(q值)用于定义q<0.05的标称统计显著性。
    结果:与对照组相比,RPL女性的子宫内膜样本中crispacilluscrispatus较少(平均相对丰度17.2%对45.6%,q=0.04)。阴道加德纳菌在RPL组中比在两个子宫内膜中的对照组更丰富(12.4%对5.8%,q<0.001)和阴道(8.7%对5.7%,q=0.002)样品。个体阴道和子宫内膜微生物组成密切相关(R=0.85,P<0.001)。在22%的子宫内膜和36%的阴道样品中检测到真菌。
    结论:生殖道微生物群的菌群失调与RPL相关,可能是妊娠流产的新危险因素。
    OBJECTIVE: Is the composition of the endometrial or vaginal microbiota associated with recurrent pregnancy loss (RPL)?
    METHODS: Endometrial and vaginal samples were collected from 47 women with two or more consecutive pregnancy losses and 39 healthy control women without a history of pregnancy loss, between March 2018 and December 2020 at Helsinki University Hospital, Helsinki, Finland. The compositions of the endometrial and vaginal microbiota, analysed using 16S rRNA gene amplicon sequencing, were compared between the RPL and control women, and between individual vaginal and endometrial samples. The mycobiota composition was analysed using internal transcribed spacer 1 amplicon sequencing for a descriptive summary. The models were adjusted for body mass index, age and parity. False discovery rate-corrected P-values (q-values) were used to define nominal statistical significance at q < 0.05.
    RESULTS: Lactobacillus crispatus was less abundant in the endometrial samples of women with RPL compared with controls (mean relative abundance 17.2% versus 45.6%, q = 0.04). Gardnerella vaginalis was more abundant in the RPL group than in controls in both endometrial (12.4% versus 5.8%, q < 0.001) and vaginal (8.7% versus 5.7%, q = 0.002) samples. The individual vaginal and endometrial microbial compositions correlated strongly (R = 0.85, P < 0.001). Fungi were detected in 22% of the endometrial and 36% of the vaginal samples.
    CONCLUSIONS: Dysbiosis of the reproductive tract microbiota is associated with RPL and may represent a novel risk factor for pregnancy losses.

    根据各种流行病学研究,复发性流产(RM)的病因是多因素的。这项研究的目的是了解更多关于遗传多态性和RM之间的联系。
    为了评估5-甲基四氢叶酸-同型半胱氨酸甲基转移酶(MTR)A2756G,5-甲基四氢叶酸-同型半胱氨酸甲基转移酶还原酶(MTRR)A66G和胱硫醚β-合酶(CBS)844INS68遗传多态性与RM的关系,并了解所选基因型的联合作用。
    这是一家医院,病例控制,观察性研究。
    本研究共招募了516名参与者,其中200例RM病例和258例对照纳入本研究。从所有参与者中抽取空腹血样(~5ml),筛选MTRA2756G基因多态性,MTRRA66G和CBS844INS68。
    频率,对奇数比和哈代-温伯格均衡进行了评估。使用SPSS(21.0版)进行数据分析。
    MTRA2756G基因多态性与RM风险无关。MTRRA66G的祖先等位基因和CBS844INS68的突变等位基因导致RM的风险增加了两倍以上。CBS844INS68与MTRA2756G联合发现,RM的风险增加了两倍以上。
    遗传多态性,特别是MTRRA66G和CBS844INS68似乎正在增加风险,因此使女性容易患RM。
    UNASSIGNED: According to various epidemiological studies, the aetiology of recurrent miscarriages (RMs) is multifactorial. The goal of this study is to learn more about the link between genetic polymorphisms and RM.
    UNASSIGNED: To evaluate the association of 5-Methytetrahydrofolate-Homocysteine Methyltransferase (MTR) A2756G, 5-Methytetrahydrofolate-Homocysteine Methyltransferase Reductase (MTRR) A66G and cystathionine beta-synthase (CBS) 844INS68 genetic polymorphisms with RM and also to understand the combined effect of the selected genotypes.
    UNASSIGNED: This was a hospital-based, case-control, observational study.
    UNASSIGNED: A total of 516 participants were recruited in the present study, of which 200 RM cases and 258 controls were included in the present study. Fasting blood sample (~5ml) was drawn from all the participants and were screened for genetic polymorphisms of MTR A2756G, MTRR A66G and CBS 844INS68.
    UNASSIGNED: The frequency, odd\'s ratio and Hardy-Weinberg equilibrium were evaluated. SPSS (version 21.0) was used for the data analysis.
    UNASSIGNED: MTR A2756G genetic polymorphism was not associated with the risk of RM. The ancestral allele of MTRR A66G and the mutant allele of CBS 844INS68 was causing an increased risk of more than two folds for RM. CBS 844INS68 in combination with MTR A2756G was found to pose an increased risk of more than two folds for RM.
    UNASSIGNED: Genetic polymorphisms particularly MTRR A66G and CBS 844INS68 seems to be elevating the risk and hence making women susceptible for RM.

    背景:恢复性生殖医学代表了一种通过调查来治疗不孕症(不孕症和流产)的综合方法,诊断,和治疗结合生育图,以恢复最佳的生殖功能。恢复性生殖医学假设需要识别和治疗多种因素(周期优化)长达12个周期才能成功怀孕。在没有宫腔内授精或体外受精的情况下,可以在正常性交时发生受孕。
    方法:一名35岁的克罗地亚女性于2019年5月接受生育治疗,先前诊断为多囊卵巢,16年的不孕症,和8次失败的体外受精和卵胞浆内单精子注射胚胎移植。她在2002年和2004年妊娠5-6周时自然受孕后有2次流产,随后在2011年妊娠12周时体外受精后流产。我们最初发现卵泡功能较差,孕酮水平欠佳。恢复性生殖医学治疗在两个治疗周期后导致受孕。这次怀孕在7周4天以流产结束。其他研究发现了平衡的罗伯逊易位(13,14)和子宫隔膜。在切除子宫隔膜并使用来曲唑和人绒毛膜促性腺激素诱导排卵后,经过三个周期的治疗,我们通过恢复性生殖医学实现了重复受精。她在2021年有足月健康怀孕和活产。
    结论:我们建议对潜在因素进行全面评估,多达12个周期的周期优化,在考虑体外受精治疗之前,应将其提供给未生育的患者。
    BACKGROUND: Restorative reproductive medicine represents a comprehensive approach to subfertility (infertility and miscarriage) with investigations, diagnoses, and treatments combined with fertility charting to restore optimal reproductive function. Restorative reproductive medicine assumes that multiple factors need to be identified and treated (cycle optimization) for up to 12 cycles to achieve a successful pregnancy. Conception can occur during normal intercourse without intrauterine insemination or in vitro fertilization.
    METHODS: A 35-year-old Croatian female presented for fertility treatment in May 2019 with a previous diagnosis of polycystic ovaries, infertility of 16 years duration, and 8 unsuccessful embryo transfers with in vitro fertilization and intracytoplasmic sperm injection. She was gravida 3 para 0, with 2 miscarriages after spontaneous conception at 5-6 weeks gestation in 2002 and 2004, followed by a miscarriage after in vitro fertilization at 12 weeks gestation in 2011. We initially found poor follicle function and suboptimal progesterone levels. Restorative reproductive medicine treatment resulted in conception after two cycles of treatment. This pregnancy ended in miscarriage at 7 weeks 4 days. Additional investigations found a balanced Robertsonian translocation (13, 14) and a uterine septum. We achieved repeat fertilization with restorative reproductive medicine after three cycles of treatment following resection of the uterine septum and ovulation induction with letrozole and human chorionic gonadotrophin. She had a full-term healthy pregnancy and live birth in 2021.
    CONCLUSIONS: We propose that a full evaluation of underlying factors, and up to 12 cycles of cycle optimization, should be offered to subfertile patients before considering in vitro fertilization treatment.

    复发性妊娠丢失(RPL)的发病机理是多因素的,尚未完全阐明。免疫失调与RPL有关,其中调节性T细胞(Tregs)是关键。由于Tregs的发育和功能受到叉头盒P3(FOXP3)转录因子的调控,由于FOXP3的表达是由基因决定的,提示FOXP3多态性在RPL发病机制中的作用.
    研究rs2294021、rs2232365、rs3761548和rs141704699FOXP3变异与黎巴嫩女性特发性RPL的关系。
    这项回顾性病例对照研究包括386例RPL病例和398例年龄匹配的对照妇女。调整后,用95%置信区间估计Logistic比值比(OR);设置P<0.05的显著性值。
    与对照组相比,特发性RPL患者的rs22944021和rs222365次要等位基因频率(MAF)显着降低。此外,在对照组中观察到杂合和纯合rs2294021和rs222365基因型的统计学显着降低的频率,而显着较低的rs3761548杂合基因型频率在患者组中发现。肥胖,抗高血压治疗,吸烟,RPL家族史阳性,堕胎状态,和不孕症治疗与rs2294021负相关,而rs222365与肥胖负相关,rs3761548与不孕症治疗呈负相关。在FOXP3SNP中注意到标记的连锁不平衡(LD),TGCC和CGAC单倍型为阳性,而中国民航,CACC,TGAC单倍型与RPL风险呈负相关。除了CGAC,这些单倍型与RPL的关联在调整后仍然存在.
    FOXP3基因变异体和单倍型与RPL发生率的改变有关,提示Treg在RPL发病机制中的作用。
    The pathogenesis of recurrent pregnancy loss (RPL) is multifactorial and not completely elucidated. Dysregulated immunity was implicated with RPL, in which regulatory T cells (Tregs) are key. As Tregs development and function are regulated by forkhead box P3 (FOXP3) transcription factor, and as FOXP3 expression is genetically determined, a role for FOXP3 polymorphisms in RPL pathogenesis was suggested.
    To investigate the association of rs2294021, rs2232365, rs3761548, and rs141704699 FOXP3 variants with idiopathic RPL in Lebanese women.
    This retrospective case-control study included 386 RPL cases and 398 age-matched control women. Logistic odds ratios (OR) were estimated with 95% confidence interval after adjustment; a significance value of P<.05 was set.
    Significantly lower rs22944021 and rs2232365 minor allele frequency (MAF) was found in patients with idiopathic RPL in comparison with the control group. Furthermore, statistically significantly lower frequency of heterozygous and homozygous rs2294021 and rs2232365 genotypes was seen in controls, while significantly lower rs3761548 heterozygous genotype frequencies were found in the patient group. Obesity, antihypertension treatment, smoking, positive RPL family history, abortion state, and infertility treatment correlated negatively with rs2294021, while rs2232365 negatively correlated with obesity, and rs3761548 negatively correlated with infertility treatment. Marked linkage disequilibrium (LD) was noted among FOXP3 SNPs, with TGCC and CGAC haplotypes being positive, while CAAC, CACC, and TGAC haplotypes being negatively associated with RPL risk. Except for CGAC, the association of these haplotypes with RPL persisted after adjustment.
    FOXP3 gene variants and haplotypes are associated with altered incidence of RPL, proposing the role of Treg in RPL pathogenesis.
