Abstract
A balance between pro-inflammatory decidual CD4+ T cells and FOXP3+ regulatory T cells (FOXP3+ Tregs) is important for maintaining fetomaternal tolerance. Using single-cell RNA-sequencing and T cell receptor repertoire analysis, we determined that diversity and clonality of decidual CD4+ T cell subsets depend on gestational age. Th1/Th2 intermediate and Th1 subsets of CD4+ T cells were clonally expanded in both early and late gestation, whereas FOXP3+ Tregs were clonally expanded in late gestation. Th1/Th2 intermediate and FOXP3+ Treg subsets showed altered gene expression in preeclampsia (PE) compared to healthy late gestation. The Th1/Th2 intermediate subset exhibited elevated levels of cytotoxicity-related gene expression in PE. Moreover, increased Treg exhaustion was observed in the PE group, and FOXP3+ Treg subcluster analysis revealed that the effector Treg like subset drove the Treg exhaustion signatures in PE. The Th1/Th2 intermediate and effector Treg like subsets are possible inflammation-driving subsets in PE.

Abstract
OBJECTIVE To describe maternal and fetal outcomes of pregnancies after 42 years and to compare maternal and fetal morbidities according to the conception mode; comparing pregnancies obtained spontaneously and those resulting from assisted reproductive technology (ART). METHODS This retrospective cohort study was conducted in a level 3 maternity hospital. This study covered all women, aged 42 years or older, who gave birth between January 1, 2014 and December 31, 2019. Univariate and multivariate analyses with logistic regression models were used to compare maternal and perinatal outcomes depending on conception mode: spontaneous or using ART. RESULTS A sample of 532 women, including 335 spontaneous pregnancies (63%) and 147 pregnancies after ART (27.6%) were studied. Conception mode was missing for 50 (9.4%). We found increased rates not only of maternal complications such as maternal overweight and obesity, pre-eclampsia, and gestational diabetes, but also of interventions such as hospitalization during pregnancy, cesarean section, postpartum hemorrhage, and perinatal outcome like preterm birth. There were also more maternal and perinatal negative outcomes among the ART group. After multivariate analysis, pre-eclampsia was predominant in the ART group (odds ratio 0.25, 95% confidence interval 0.07-0.85, P = 0.02). CONCLUSION While maternal and fetal risks increase for late pregnancies, there also appears to be a difference depending on the conception mode, with pregnancies resulting from ART having more pregnancy-related complications than those obtained spontaneously.

Abstract
PURPOSE In this first of two companion papers, we critically review the evidence recently published in the primary literature, which addresses adverse maternal and neonatal pregnancy outcomes associated with programmed embryo transfer cycles. We next consider whether these pathological pregnancy outcomes might be attributable to traditional risk factors, unknown parental factors, embryo culture, culture duration, or cryopreservation. Finally, in the second companion article, we explore potential etiologies and suggest strategies for prevention. METHODS Comprehensive review of primary literature. RESULTS The preponderance of retrospective and prospective observational studies suggests that increased risk for hypertensive disorders of pregnancy (HDP) and preeclampsia in assisted reproduction involving autologous embryo transfer is associated with programmed cycles. For autologous frozen embryo transfer (FET) and singleton live births, the risk of developing HDP and preeclampsia, respectively, was less for true or modified natural and stimulated cycles relative to programmed cycles: OR 0.63 [95% CI (0.57-0.070)] and 0.44 [95% CI (0.40-0.50)]. Though data are limited, the classification of preeclampsia associated with programmed autologous FET was predominantly late-onset or term disease. Other adverse pregnancy outcomes associated with autologous FET, especially programmed cycles, included increased prevalence of large for gestational age infants and macrosomia, as well as higher birth weights. In one large registry study, FET was associated with fetal overgrowth of a symmetrical nature. Postterm birth and placenta accreta not associated with prior cesarean section, uterine surgery, or concurrent placenta previa were also associated with autologous FET, particularly programmed cycles. The heightened risk of these pathologic pregnancy outcomes in programmed autologous FET does not appear to be attributable to traditional risk factors, unknown parental factors, embryo culture, culture duration, or cryopreservation, although the latter may contribute a modest degree of increased risk for fetal overgrowth and perhaps HDP and preeclampsia in FET irrespective of the endometrial preparation. CONCLUSIONS Programmed autologous FET is associated with an increased risk of several, seemingly diverse, pathologic pregnancy outcomes including HDP, preeclampsia, fetal overgrowth, postterm birth, and placenta accreta. Though the greater risk for preeclampsia specifically associated with programmed autologous FET appears to be well established, further research is needed to substantiate the limited data currently available suggesting that the classification of preeclampsia involved is predominately late-onset or term. If substantiated, then this knowledge could provide insight into placental pathogenesis, which has been proposed to differ between early- and late-onset or term preeclampsia (see companion paper for a discussion of potential mechanisms). If a higher prevalence of preeclampsia with severe features as suggested by some studies is corroborated in future investigations, then the danger to maternal and fetal/neonatal health is considerably greater with severe disease, thus increasing the urgency to find preventative measures. Presupposing significant overlap of these diverse pathologic pregnancy outcomes within subjects who conceive by programmed embryo transfer, there may be common etiologies.

Abstract
PURPOSE In the first of two companion papers, we comprehensively reviewed the recent evidence in the primary literature, which addressed the increased prevalence of hypertensive disorders of pregnancy, late-onset or term preeclampsia, fetal overgrowth, postterm birth, and placenta accreta in women conceiving by in vitro fertilization. The preponderance of evidence implicated frozen embryo transfer cycles and, specifically, those employing programmed endometrial preparations, in the higher risk for these adverse maternal and neonatal pregnancy outcomes. Based upon this critical appraisal of the primary literature, we formulate potential etiologies and suggest strategies for prevention in the second article. METHODS Comprehensive review of primary literature. RESULTS Presupposing significant overlap of these apparently diverse pathological pregnancy outcomes within subjects who conceive by programmed autologous FET cycles, shared etiologies may be at play. One plausible but clearly provocative explanation is that aberrant decidualization arising from suboptimal endometrial preparation causes greater than normal trophoblast invasion and myometrial spiral artery remodeling. Thus, overly robust placentation produces larger placentas and fetuses that, in turn, lead to overcrowding of villi within the confines of the uterine cavity which encroach upon intervillous spaces precipitating placental ischemia, oxidative and syncytiotrophoblast stress, and, ultimately, late-onset or term preeclampsia. The absence of circulating corpus luteal factors like relaxin in most programmed cycles might further compromise decidualization and exacerbate the maternal endothelial response to deleterious circulating placental products like soluble fms-like tyrosine kinase-1 that mediate disease manifestations. An alternative, but not mutually exclusive, determinant might be a thinner endometrium frequently associated with programmed endometrial preparations, which could conspire with dysregulated decidualization to elicit greater than normal trophoblast invasion and myometrial spiral artery remodeling. In extreme cases, placenta accreta could conceivably arise. Though lower uterine artery resistance and pulsatility indices observed during early pregnancy in programmed embryo transfer cycles are consistent with this initiating event, quantitative analyses of trophoblast invasion and myometrial spiral artery remodeling required to validate the hypothesis have not yet been conducted. CONCLUSIONS Endometrial preparation that is not optimal, absent circulating corpus luteal factors, or a combination thereof are attractive etiologies; however, the requisite investigations to prove them have yet to be undertaken. Presuming that in ongoing RCTs, some or all adverse pregnancy outcomes associated with programmed autologous FET are circumvented or mitigated by employing natural or stimulated cycles instead, then for women who can conceive using these regimens, they would be preferable. For the 15% or so of women who require programmed FET, additional research as suggested in this review is needed to elucidate the responsible mechanisms and develop preventative strategies.

Abstract
PURPOSE To analyze the perinatal and maternal outcomes of women ranging in age from 40 to 45 years who gave birth after in vitro fertilization or oocyte donation, compared to spontaneous conception. METHODS This retrospective cohort study used electronic data from a national healthcare service from 2000 through 2019. Three groups were compared: spontaneous pregnancy (SC), in vitro fertilization (IVF) utilizing autologous oocytes, and pregnancies resulting from oocyte donation (OD). The primary study outcomes were preterm labor (PTL) before 37 weeks of gestation, and infants classified as small for gestational age (SGA). RESULTS The cohort included 26,379 SC, 2237 IVF pregnancies, and 300 OD pregnancies for women ages 40-45 years at delivery. Women with OD or IVF had a higher incidence of PTL < 37 weeks compared to women with SC (19.7% vs. 18% vs. 6.9%, p = 0.001), PTL < 34 (7% vs. 4.5% vs. 1.4%, p = 0.001), PTL < 32 (3.7 vs. 2.1 vs. 0.6, p = 0.001). A multivariable logistic regression for PTL < 37 weeks demonstrated that age (OR = 1.18) and hypertensive diseases (OR = 3.4) were statistically significant factors. The OD group had a lower rate of SGA compared to SC (1% vs. 4.3%, p = 0.001), while the IVF group had a higher rate of SGA compared to SC (9.1% vs. 4.3%, p = 0.001). Hypertensive diseases in pregnancy were significantly higher among the OD group and the IVF group compared to SP pregnancies (3.3% vs. 1%, p = 0.002; 2.3% vs. 1%, p = 0.001, respectively). CONCLUSIONS Women ages 40-45 undergoing IVF or OD have a greater risk of PTL, possibly due to higher rates of hypertensive disorders of pregnancy.

Abstract
Autophagy is a bulk degradation system that maintains cellular homeostasis by producing energy and/or recycling excess proteins. During early placentation, extravillous trophoblasts invade the decidua and uterine myometrium, facing maternal immune cells, which participate in the immune suppression of paternal and fetal antigens. Regulatory T cells will likely increase in response to a specific antigen before and during early pregnancy. Insufficient expansion of antigen-specific Treg cells, which possess the same T cell receptor, is associated with the pathophysiology of preeclampsia, suggesting sterile systemic inflammation. Autophagy is involved in reducing inflammation through the degradation of inflammasomes and in the differentiation and function of regulatory T cells. Autophagy dysregulation induces protein aggregation in trophoblasts, resulting in placental dysfunction. In this review, we discuss the role of regulatory T cells in normal pregnancies. In addition, we discuss the association between autophagy and regulatory T cells in the development of preeclampsia based on reports on the role of autophagy in autoimmune diseases.

Abstract
The etiology of preeclampsia (PE) is still unknown, and excessive immune activation is an important component of its pathogenesis. Programmed cell death protein 1 (PD-1) is one of immune checkpoints which may prevent overactivated immune attack and lead to a tolerant immune microenvironment. Little is known about the involvement of PD-1-mediated immunoregulation at the maternal-fetal interface in PE. To investigate the inflammatory pattern and the involvement of PD-1 in the decidua of women with PE, decidual tissues were obtained from PE and control pregnant women. Quantitative RT-PCR analysis of the mRNA levels of the inflammatory cytokines was performed. PD-1 expression was detected by immunohistochemistry, western blot analysis, and flow cytometry. To prove the role of PD-1, decidual immune cells were incubated with blocking antibodies, and the inflammatory cytokines were detected by ELISA. We observed that the mRNA levels of IL-1β, IL-6, TNF-α, and IFN-γ were higher in the decidua of the PE group than in the decidua of the control group. The mRNA levels of IL-4 and IL-10 were lower in PE. The expression level of PD-1 was significantly downregulated, and the proportion (%) of PD-1 + CD45 + cells was significantly lower in PE. There was a significant linear correlation between PD-1 expression and common proinflammatory cytokines in the decidua. Anti-PD-1 blocking antibody significantly increased the secretion of proinflammatory cytokines. Our data suggested that the inflammatory pattern and decreased PD-1 expression in the decidua might play an active role in the local immunoregulatory mechanisms of PE. The PD-1 pathway in the maternal-fetal interface possibly function to break the tolerant immune microenvironment in PE via inflammatory cytokines.

Abstract
OBJECTIVE To determine whether pregnancies with donated embryos are at a higher risk of complications than the pregnancies from autologous frozen-thawed embryo transfer (FET). DESIGN Anonymous, multicenter, comparative, observational, retrospective, matched-cohort study. SETTING Six French assisted reproductive technique centers from 2003 to 2018. PATIENT(S) Seventy-three singleton pregnancies with donated embryos (exposed) and 136 singleton pregnancies after autologous FET (nonexposed) were matched at 7-8 weeks of gestation (pregnancy date, parity, and women's age) (2:1 ratio, respectively). In accordance with French practices, all women were <44 years old and donated embryos were discarded frozen embryos from other couples. INTERVENTION(S) Not applicable. MAIN OUTCOME MEASURE(S) Percentages of hypertensive disorders of pregnancy (HDPs) with donated embryos versus autologous FET. RESULT(S) Groups were comparable (mean age: 34.5 years) and HDPs (24.6% vs. 11.9%) were significantly more frequent among the donated-embryo pregnancies, mostly in its severe forms (17.5% vs. 4.6%). In contrast, their respective isolated hypertension frequencies were comparable (7.0% vs. 7.3%). Multivariate analysis retained increased severe HDP risk with donated embryos (odds ratio 2.08 [95% confidence interval: 1.08-4.02]). No significant effect of endometrial preparation was observed. C-sections were more frequent for donated-embryo pregnancies (47.3% vs. 29.2%). Newborns from embryo donation or autologous FET were comparable for prematurity, birth weight and length, Apgar score, small for gestational age, large for gestational age, neonatal malformations, and sex ratio. CONCLUSION(S) Even for young women, the risk of severe HDP was 4 times higher for donated-embryo pregnancies than for autologous-FET pregnancies. The HDP risk must be acknowledged to inform donated-embryo recipients and provide careful pregnancy monitoring.

Follicle development and its prediction in patients with primary ovarian insufficiency: Possible treatments and markers to maximize the ability to conceive with residual follicles.

Abstract
Background Primary ovarian insufficiency (POI) is characterized by the development of hypergonadotropic hypogonadism before 40 years of age and leads to intractable infertility. Although in vitro fertilization and embryo transfer with donated eggs enables pregnancy, not a few patients desire pregnancy using their oocytes. However, follicular development is rare and unpredictable in patients with POI. Thus, there is a need for treatments that promote the development of residual follicles and methods to accurately predict infrequent ovulation. Methods This review discusses the effects of various treatments for obtaining eggs from POI patients. Furthermore, this study focused a potential marker for predicting follicular growth in patients with POI. Main Findings Different treatments such as hormone-replacement therapy, dehydroepiandrosterone supplementation, platelet-rich plasma injection, and in vitro activation have shown varying degrees of effectiveness in retrieving oocytes from patients with POI. To predict follicle development in the cycle, elevated serum estradiol and reduced follicle-stimulating hormone (FSH) levels are important. However, these markers are not always reliable under continuous estradiol-replacement therapy. As a novel marker for predicting follicle growth, serum anti-Müllerian hormone (AMH) levels, measured using the picoAMH enzyme-linked immunosorbent assay, were found to predict follicle growth in patients and the cycle. Conclusion This review highlights the challenges and available interventions for achieving pregnancy using a patient's oocytes in cases of POI. We believe that a combination of currently available treatments and prediction methods is the best strategy to enable patients with POI to conceive using their own eggs. Although AMH levels may predict follicle growth, further research is necessary to improve the chances of successful follicular development and conception in patients with POI.

Gao X, Sun S, Xie L, Lu S. Effects of donor sperm on perinatal and neonatal outcomes resulting from in vitro fertilization-intracytoplasmic sperm injection and embryo transfer cycles: a retrospective cohort study. ANNALS OF TRANSLATIONAL MEDICINE 2022; 10:819. [PMID: 36034991 PMCID: PMC9403916 DOI: 10.21037/atm-21-5492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Accepted: 06/24/2022] [Indexed: 12/02/2022]
Abstract
Background The impact of donor sperm on pregnancy outcomes is controversial. The aim of this study was to investigate whether donor sperm in in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatment could reduce the rate of live births or increase the incidence of adverse pregnancy outcomes and birth defects in neonates. Methods This single-centre, retrospective cohort study included 1,559 patients with infertility who received donor sperm at our hospital from 2015 to 2019. All the patients received fresh embryos and underwent first-cycle transfer. After propensity score matching, 4,677 controls who received their partners’ sperm were matched at 1:3. Clinical pregnancy, perinatal, and neonatal outcomes were compared between the donor sperm and partner sperm groups. Results The embryo development was better in the donor sperm group than in the partner sperm group. The high-quality embryo and available embryo rates were significantly higher in the donor sperm group (P<0.05 for both groups). The rate of high-quality embryos transferred from the donor sperm group was higher than that from the partner sperm group (P<0.05). The clinical pregnancy (62.99% vs. 59.65%; P=0.02) and live birth (54.65% vs. 51.59%; P=0.036) rates were higher in the donor sperm group. After adjusting for confounding factors, no significant difference in live birth rates was observed between the two groups (adjusted P=0.057). The low birthweight (18.21% vs. 21.39%; P=0.023) and small for gestational age (SGA) (7.60% vs. 11.97%; P<0.001) rates were lower in the donor sperm group. To exclude the effect of multiple pregnancies, we evaluated neonatal outcomes of singleton pregnancies. No significant differences were noted in preterm and very preterm birth, SGA, mean birthweight, high birthweight, and low birth weight (LBW) and very low birth weight (VLBW) rates (P>0.05 for both groups). Further, no significant between group differences were observed in the ectopic pregnancy rate, early and late spontaneous abortion rates, gestational age, rate of large for gestational age (LGA), and neonatal defects. Conclusions Compared with partner sperm, donor sperm did not reduce live birth rate and did not increase neonatal LBW or low birth defects.

Abstract
Members of the innate immune system, innate lymphoid cells (ILCs), encompass five major populations (Natural Killer (NK) cells, ILC1s, ILC2s, ILC3s, and lymphoid tissue inducer cells) whose functions include defense against pathogens, surveillance of tumorigenesis, and regulation of tissue homeostasis and remodeling. ILCs are present in the uterine environment of humans and mice and are dynamically regulated during the reproductive cycle and pregnancy. These cells have been repurposed to support pregnancy promoting maternal immune tolerance and placental development. To accomplish their tasks, immune cells employ several cellular and molecular mechanisms. They have the capacity to remember a previously encountered antigen and mount a more effective response to succeeding events. Memory responses are not an exclusive feature of the adaptive immune system, but also occur in innate immune cells. Innate immune memory has already been demonstrated in monocytes/macrophages, neutrophils, dendritic cells, and ILCs. A population of decidual NK cells characterized by elevated expression of NKG2C and LILRB1 as well as a distinctive transcriptional and epigenetic profile was found to expand during subsequent pregnancies in humans. These cells secrete high amounts of interferon-γ and vascular endothelial growth factor likely favoring placentation. Similarly, uterine ILC1s in mice upregulate CXCR6 and expand in second pregnancies. These data provide evidence on the development of immunological memory of pregnancy. In this article, the characteristics, functions, and localization of ILCs are reviewed, emphasizing available data on the uterine environment. Following, the concept of innate immune memory and its mechanisms, which include epigenetic changes and metabolic rewiring, are presented. Finally, the emerging role of innate immune memory on reproduction is discussed. Advances in the comprehension of ILC functions and innate immune memory may contribute to uncovering the immunological mechanisms underlying female fertility/infertility, placental development, and distinct outcomes in second pregnancies related to higher birth weight and lower incidence of complications.

Abstract
Studies in the gravid rat model revealed a key role for the corpus luteal hormone, relaxin, in the maternal circulatory changes of early pregnancy epitomized by profound systemic vasodilation and increased arterial compliance. To determine whether the corpus luteum may play a similar role in human pregnancy, women who conceived by in vitro fertilization were studied. Implementation of artificial (programmed) cycles for embryo transfers, which precluded the formation of a corpus luteum, was associated with notable attenuation of the gestational rise in cardiac output and fall in carotid-femoral pulse wave velocity (reflecting impairment of arterial dilation and increased compliance, respectively) and deficiencies in other cardiovascular changes normally observed during the first trimester. Cardiac output and carotid-femoral pulse wave velocity were restored after the first trimester of pregnancy, consistent with rescue by placental vasodilators, such as placental growth factor. In addition, a potential role of corpus luteal factors in reducing the risk of developing preeclampsia was hypothesized. In most single and multiple center, prospective and retrospective cohort (and registry) studies, the risk of developing preeclampsia and preeclampsia with severe features was increased specifically in women undergoing autologous frozen embryo transfer in artificial cycles without the formation of a corpus luteum relative to natural, modified natural, stimulated, or controlled ovarian stimulation cycles and spontaneous pregnancies-all associated with the formation of at least 1 corpus luteum. Taken together, these observational studies are sufficiently compelling to warrant randomized clinical trials comparing preeclampsia risk in autologous frozen embryo transfer in natural vs artificial cycles. Impaired endometrial function because of suboptimal hormonal administration is an alternative but not mutually exclusive explanation for increased preeclampsia risk in autologous frozen embryo transfer in artificial cycles. Potential mechanisms by which the corpus luteum may reduce the risk of developing preeclampsia and whether autologous frozen embryo transfer in artificial cycles is associated with increased risk of preterm preeclampsia, term preeclampsia, or both are discussed. Last, suggestions for future investigations are noted.

Abstract
Preeclampsia is a disease whose characterization has not changed in the 150 years since the cluster of signs associated with the disorder were first described. Although our understanding of the pathophysiology of preeclampsia has advanced considerably since then, there is still little consensus regarding the true etiology of preeclampsia. As a consequence, preeclampsia has earned the moniker "disease of theories," predominantly because the underlying biological mechanisms linking clinical epidemiologic findings to observed organ dysfunction in preeclampsia are far from clear. Despite the lack of cohesive evidence, expert consensus favors the hypothesis that preeclampsia is a primary placental disorder. However, there is now emerging evidence that suboptimal maternal cardiovascular performance resulting in uteroplacental hypoperfusion is more likely to be the cause of secondary placental dysfunction in preeclampsia. Preeclampsia and cardiovascular disease share the same risk factors, preexisting cardiovascular disease is the strongest risk factor (chronic hypertension, congenital heart disease) for developing preeclampsia, and there are now abundant data from maternal echocardiography and angiogenic marker studies that cardiovascular dysfunction precedes the development of preeclampsia by several weeks or months. Importantly, cardiovascular signs and symptoms (hypertension, cerebral edema, cardiac dysfunction) predominate in preeclampsia at clinical presentation and persist into the postnatal period with a 30% risk of chronic hypertension in the decade after birth. Placental malperfusion caused by suboptimal maternal cardiovascular performance may lead to preeclampsia, thereby explaining the preponderance of cardiovascular drugs (aspirin, calcium, statins, metformin, and antihypertensives) in preeclampsia prevention strategies. Despite the seriousness of the maternal and fetal consequences, we are still developing sensitive screening, reliable diagnostic, effective therapeutic, or improvement strategies for postpartum maternal cardiovascular legacy in preeclampsia. The latter will only become clear with an acceptance and understanding of the cardiovascular etiology of preeclampsia.

Abstract
STUDY QUESTION What is the prevalence of pre-eclampsia (PE) in pregnancies after oocyte donation (OD) compared to natural conception (NC) and to IVF with autologous oocytes (AO)? SUMMARY ANSWER Overall the prevalence of PE after OD was 4-5 times higher than after NC and 2-3 times higher than after IVF with AO. WHAT IS KNOWN ALREADY The indication for OD is expanding to lesbian women requesting shared lesbian motherhood. Previous reviews have shown that the risk of PE is higher in pregnancies after OD than after NC and after IVF with AO. Classification on the severity of PE is lacking as is the relationship with known risk factors such as maternal age and multiple gestations. Furthermore the actual prevalence of PE in pregnancies resulting from OD is not known. STUDY DESIGN, SIZE, DURATION A systematic review and meta-analysis was conducted. A literature search was performed using the following databases: PubMed, EMBASE and CINAHL, OpenGrey and Greynet from January 1980 through July 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS We included retrospective and prospective cohort studies. The study population consisted of pregnancies after OD and NC or IVF and data had to be available about prevalence of PE. We compared the risk of (severe) PE in OD versus NC and IVF pregnancies, subgrouped by plurality and maternal age. We calculated individual and pooled odds ratios (OR) and prevalence estimates with 95% CI using a random effect model, while heterogeneity was assessed by the I2. MAIN RESULTS AND THE ROLE OF CHANCE In total, 27 studies comprising of 7089 OD pregnancies, 1 139 540 NC pregnancies and 72 742 IVF pregnancies were available for analysis. The risks of PE and severe PE was increased in OD pregnancies compared to NC pregnancies (pooled OR of all subgroups: 5.09, 95% CI: 4.29-6.04; I2 = 19% and OR: 7.42, 95% CI: 4.64-11.88; I2 = 49%, respectively). This suggests that compared to a PE risk of 2.9% with NC, the risk with OD was between 11.5% and 15.4%. Compared to a severe PE risk of 0.5% with NC, the risk with OD was between 2.3% and 5.6%. The pooled adjusted OR for PE was 3.24 (95% 2.74-3.83) for OD versus NC pregnancies. The risks of PE and severe PE were also increased in OD pregnancies compared to IVF pregnancies (pooled OR of all subgroups: 2.97, 95% CI: 2.49-3.53; I2 = 51% and OR: 2.97, 95% CI: 2.15-4.11; I2 = 0%, respectively). This suggests that compared to a PE risk of 5.9% with IVF, the risk with OD was between 13.5% and 18.0%. Compared to a severe PE risk of 3.3% with IVF, the risk with OD was between 6.8% and 12.2%. The pooled adjusted OR for PE was 2.67 (95% 2.28-3.13) for OD versus IVF. The pooled prevalence of PE in singleton pregnancies after OD was 10.7% (95% CI 6.6-15.5) compared to 2.0% (95% CI 1.0-3.1) after NC and 4.1% (95% CI 2.7-5.6) after IVF. The prevalence in multiple pregnancies was 27.8% (95% CI 23.6-32.2) after OD, 7.5% (95% CI 7.2-7.8) after NC and 9.7% (95% CI 6.2-13.9) after IVF. LIMITATIONS, REASONS FOR CAUTION The precise definition of PE is still a matter of debate. The different criteria could have affected the prevalence estimate. WIDER IMPLICATIONS OF THE FINDINGS Nearly one in six women will suffer PE after OD. Although it is uncertain whether these risks are consistent for lesbian couples undergoing shared motherhood, we feel that women who can conceive naturally could be advised to reconsider. In women with primary ovarian insufficiency, we feel that factors that may increase risk of PE ever further, such as double embryo transfer, should be avoided whenever possible.

Abstract
CD8+ T cells are the most frequent T cell population in the immune cell compartment at the feto-maternal interface. Due to their cytotoxic potential, the presence of CD8+ T cells in the immune privileged pregnant uterus has raised considerable interest. Here, we review our current understanding of CD8+ T cell biology in the uterus of pregnant women and discuss this knowledge in relation to a recently published immune cell Atlas of human decidua. We describe how the expansion of CD8+ T cells with an effector memory phenotype often presenting markers of exhaustion is critical for a successful pregnancy, and host defense towards pathogens. Moreover, we review new evidence on the presence of long-lasting immunological memory to former pregnancies and discuss its impact on prospective pregnancy outcomes. The formation of fetal-specific memory CD8+ T cell subests in the uterus, in particular of tissue resident, and stem cell memory cells requires further investigation, but promises interesting results to come. Advancing the knowledge of CD8+ T cell biology in the pregnant uterus will be pivotal for understanding not only tissue-specific immune tolerance but also the etiology of complications during pregnancy, thus enabling preventive or therapeutic interventions in the future.

Definition of a clinical strategy to enhance the efficacy, efficiency and safety of egg donation cycles with imported vitrified oocytes. Hum Reprod 2021; 35:785-795. [PMID: 32240287 DOI: 10.1093/humrep/deaa009] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2019] [Revised: 01/13/2020] [Accepted: 01/17/2020] [Indexed: 01/01/2023] Open
Abstract
STUDY QUESTION Which is the most suitable clinical strategy in egg donation IVF cycles conducted with imported donated vitrified oocytes? SUMMARY ANSWER The importation, and allocation, of at least eight vitrified eggs per couple during an egg donation cycle is associated with a high cumulative live birth delivery rate per cycle, as well as the confident adoption of a single blastocyst transfer strategy to minimize the risk of multiple pregnancies. WHAT IS KNOWN ALREADY IVF using donor eggs is commonly used worldwide to treat women who are unable to conceive with their own oocytes. In 2014, the Constitutional Court (n.162/2014) gave permission for gamete donation to be allowed for ART in Italy. Initially recommended as a therapeutic approach for premature ovarian insufficiency, the use of donated oocytes has become more and more common. In countries such as Italy, fresh oocyte donation is theoretically possible, but practically impossible due to the lack of donors. In fact, the Italian law does not allow reimbursement to the young women, who can only voluntarily donate their eggs. Therefore, Italian IVF centers have established several collaborations with international oocyte cryo-banks. The most popular workflow involves the importation of donated oocytes that have been vitrified. However, recent evidence has questioned the overall efficacy of such an approach. This is because detrimental effects arising from oocyte vitrification and warming might reduce the number of eggs available for insemination, with a consequential reduction in the achievable live birth rate per cycle. STUDY DESIGN, SIZE, DURATION This was a longitudinal cohort study, conducted between October 2015 and December 2018 at two private IVF centers. Overall, 273 couples were treated (mean maternal age: 42.5 ± 3.5 years, range: 31-50 years; mean donor age: 25.7 ± 4.2, 20-35 years) with oocytes purchased from three different Spanish egg banks. PARTICIPANTS/MATERIALS, SETTING, METHODS We performed an overall analysis, as well as several sub-analyses clustering the data according to the year of treatment (2015-2016, 2017 or 2018), the number of warmed (6, 7, 8 or 9) and surviving oocytes (≤4, 5, 6, 7, 8 or 9) and the cycle strategy adopted (cleavage stage embryo transfer and vitrification, cleavage stage embryo transfer and blastocyst vitrification, blastocyst stage embryo transfer and vitrification). This study aimed to create a workflow to maximize IVF efficacy, efficiency, and safety, during egg donation cycles with imported vitrified oocytes. The primary outcome was the cumulative live birth delivery rate among completed cycles (i.e. cycles where at least a delivery of a live birth was achieved, or no embryo was produced/left to transfer). All cycles, along with their embryological, obstetric and neonatal outcomes, were registered and inspected. MAIN RESULTS AND THE ROLE OF CHANCE The survival rate after warming was 86 ± 16%. When 6, 7, 8 and 9 oocytes were warmed, 94, 100, 72 and 70% of cycles were completed, resulting in 35, 44, 69 and 59% cumulative live birth delivery rates per completed cycle, respectively. When ≤4, 5, 6, 7, 8 and 9 oocytes survived, 98, 94, 85, 84, 66 and 68% of cycles were completed, resulting in 16, 46, 50, 61, 76 and 60% cumulative live birth delivery rates per completed cycle, respectively. When correcting for donor age, and oocyte bank, in a multivariate logistic regression analysis, warming eight to nine oocytes resulted in an odds ratio (OR) of 2.5 (95% CI: 1.07-6.03, P = 0.03) for the cumulative live birth delivery rate per completed cycle with respect to six to seven oocytes. Similarly, when seven to nine oocytes survived warming, the OR was 2.7 (95% CI: 1.28-5.71, P < 0.01) with respect to ≤6 oocytes. When cleavage stage embryos were transferred, a single embryo transfer strategy was adopted in 17% of cases (N = 28/162); the live birth delivery rate per transfer was 26% (n = 43/162), but among the pregnancies to term, 28% involved twins (n = 12/43). Conversely, when blastocysts were transferred, a single embryo transfer strategy was adopted in 96% of cases (n = 224/234) with a 30% live birth delivery rate per transfer (N = 70/234), and the pregnancies to term were all singleton (n = 70/70). During the study period, 125 babies were born from 113 patients. When comparing the obstetric outcomes for the cleavage and blastocyst stage transfer strategies, the only significant difference was the prevalence of low birthweight: 34 versus 5%, respectively (P < 0.01). However, several significant differences were identified when comparing singleton with twin pregnancies; in fact, the latter resulted in a generally lower birthweight (mean ± SD: 3048 ± 566 g versus 2271 ± 247 g, P < 0.01), a significantly shorter gestation (38 ± 2 versus 36 ± 2 weeks, P < 0.01), solely Caesarean sections (72 versus 100%, P = 0.02), a higher prevalence of low birthweight (8 versus 86%, P < 0.01), small newborns for gestational age (24 versus 57%, P = 0.02) and preterm births (25 versus 86%, P < 0.01). LIMITATIONS, REASONS FOR CAUTION This retrospective study should now be confirmed across several IVF centers and with a greater sample size in order to improve the accuracy of the sub-analyses. WIDER IMPLICATIONS OF THE FINDINGS Single blastocyst transfer is the most suitable approach to achieve high success rates per procedure, thereby also limiting the obstetric complications that arise from twin pregnancies in oocyte donation programs. In this regard, the larger the cohort of imported donated vitrified oocytes, the more efficient the management of each cycle. STUDY FUNDING/COMPETING INTEREST(S) None. TRIAL REGISTRATION NUMBER None.

Abstract
Autophagy and apoptosis are catabolic pathways essential for homeostasis. They play a crucial role for normal placental and fetal development. These cell death mechanisms are exaggerated in placental disorders such as preeclampsia, intrauterine growth restriction (IUGR) and gestational diabetes mellitus (GDM). Apoptosis is widely studied, highly controlled and regulated whereas; autophagy is an orderly degradation and recycling of the cellular components. Cellular senescence may be initiated by a variety of stimuli, including hypoxia, oxidative stress, reduction in survival signals and nutrition deprivation. Apoptosis is regulated by two types of pathways intrinsic and extrinsic. Extrinsic pathway is initiated by apoptosis inducing cells such as macrophages, natural killer cells whereas; intrinsic pathway is initiated in response to DNA damage, cell injury and lack of oxygen. In autophagy, the cell or organelles undergo lysosomal degradation. Placental apoptosis increases as the gestation progresses while autophagy plays a role in trophoblast differentiation and invasion. In pregnancy disorders like preeclampsia and IUGR, proapoptotic markers such as caspase 3, 8, BAX are higher and antiapoptotic markers like Bcl-2 are lower. In GDM, apoptotic markers are reduced resulting in increased placental mass and fetal macrosomia. Apoptosis in the pathological pregnancies is also influenced by the reduced levels of micronutrients and long chain polyunsaturated fatty acids resulting in disturbed placental biology. This chapter describes the role of various key molecular events involved in cellular senescence and the various factors influencing them. This will help identify future therapeutic strategies for better management of these processes.

The role of decidual regulatory T cells in the induction and maintenance of fetal antigen-specific tolerance: Imbalance between regulatory and cytotoxic T cells in pregnancy complications. Hum Immunol 2021; 82:346-352. [PMID: 33642099 DOI: 10.1016/j.humimm.2021.01.019] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Revised: 01/10/2021] [Accepted: 01/26/2021] [Indexed: 12/13/2022]
Abstract
Fetal antigen-specific tolerance is important for maintaining allogeneic pregnancies. Maternal conventional T cells recognize fetal antigens; however, regulatory T (Treg) cells suppress immune reactions against the fetus. Fetal antigen-specific Treg cells are induced in the decidua upon contact with antigen-presenting cells and extravillous trophoblasts (EVTs). Functional alteration of cytotoxic T cells (CTLs) in the decidua also contributes to maintaining the pregnancy. Reduced, dysfunctional, and imbalanced Treg cell distribution likely contributes to the pathogenesis of pregnancy complications, such as miscarriage and preeclampsia. Recent studies have revealed differences in Treg cell characteristics during preeclampsia and miscarriage. Treg cell reduction in the decidua is likely associated with miscarriage. Insufficient expansion of fetal antigen-specific Treg cells in the decidua probably plays a role in preeclampsia pathogenesis. In addition, the balance between Treg cell-mediated tolerance and functional alteration of CTLs is important. Further investigations of functional molecules in Treg cells will contribute to the development of immunotherapy for pregnancy complications.

Allen CP, Marconi N, McLernon DJ, Bhattacharya S, Maheshwari A. Outcomes of pregnancies using donor sperm compared with those using partner sperm: systematic review and meta-analysis. Hum Reprod Update 2020; 27:190-211. [PMID: 33057599 DOI: 10.1093/humupd/dmaa030] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 05/25/2020] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Registry data from the Human Fertilisation and Embryology Authority (HFEA) show an increase of 40% in IUI and 377% in IVF cases using donor sperm between 2006 and 2016. OBJECTIVE AND RATIONALE The objective of this study was to establish whether pregnancies conceived using donor sperm are at higher risk of obstetric and perinatal complications than those conceived with partner sperm. As more treatments are being carried out using donor sperm, attention is being given to obstetric and perinatal outcomes, as events in utero and at delivery have implications for long-term health. There is a need to know if there is any difference in the outcomes of pregnancies between those conceived using donor versus partner sperm in order to adequately inform and counsel couples. SEARCH METHODS We performed a systematic review and meta-analysis of the outcomes of pregnancies conceived using donor sperm compared with partner sperm. Searches were performed in the OVID MEDLINE, OVID Embase, CENTRAL and CINAHL databases, including all studies published before 11 February 2019. The search strategy involved search terms for pregnancy, infant, donor sperm, heterologous artificial insemination, donor gametes, pregnancy outcomes and perinatal outcomes. Studies were included if they assessed pregnancies conceived by any method using, or infants born from, donor sperm compared with partner sperm and described early pregnancy, obstetric or perinatal outcomes. The Downs and Black tool was used for quality and bias assessment of studies. OUTCOMES Of 3391 studies identified from the search, 37 studies were included in the review and 36 were included in the meta-analysis. For pregnancies conceived with donor sperm, versus partner sperm, there was an increase in the relative risk (RR) (95% CI) of combined hypertensive disorders of pregnancy: 1.44 (1.17-1.78), pre-eclampsia: 1.49 (1.05-2.09) and small for gestational age (SGA): 1.42 (1.17-1.79) but a reduced risk of ectopic pregnancy: 0.69 (0.48-0.98). There was no difference in the overall RR (95% CI) of miscarriage: 0.94 (0.80-1.11), gestational diabetes: 1.49 (0.62-3.59), pregnancy-induced hypertension (PIH): 1.24 (0.87-1.76), placental abruption: 0.65 (0.04-10.37), placenta praevia: 1.19 (0.64-2.21), preterm birth: 0.98 (0.88-1.08), low birth weight: 0.97 (0.82-1.15), high birthweight: 1.28 (0.94-1.73): large for gestational age (LGA): 1.01 (0.84-1.22), stillbirth: 1.23 (0.97-1.57), neonatal death: 0.79 (0.36-1.73) and congenital anomaly: 1.15 (0.86-1.53). WIDER IMPLICATIONS The majority of our findings are reassuring, except for the mild increased risk of hypertensive disorders of pregnancy and SGA in pregnancies resulting from donor sperm. However, the evidence for this is limited and should be interpreted with caution because the evidence was based on observational studies which varied in their quality and risk of bias. Further high-quality population-based studies reporting obstetric outcomes in detail are required to confirm these findings.

Analysis of TCR Repertoire and PD-1 Expression in Decidual and Peripheral CD8 + T Cells Reveals Distinct Immune Mechanisms in Miscarriage and Preeclampsia. Front Immunol 2020; 11:1082.

Abstract
CD8+ T cells, the most abundant T cell subset in the decidua, play a critical role in the maintenance of pregnancy. The majority of decidual CD8+ T cells have an effector memory phenotype, while those in the peripheral blood display a naive phenotype. An increased amount of highly differentiated CD8+ T cells in the decidua indicates local antigen stimulation and expansion, albeit these CD8+ T cells are suppressed. In decidual CD8+ T cells, co-inhibitory molecules such as PD-1, TIM-3, LAG-3, and CTLA-4 are upregulated, reflecting the suppression of cytotoxicity. Previous studies established the importance of the PD-1/PD-L1 interaction for feto-maternal tolerance. CD8+ T cells could directly recognize fetal-specific antigens, such as HLA-C, expressed by trophoblasts. However, although fetal-specific CD8+ T cells have been reported, their TCR repertoires have not been identified. In this study, we analyzed the TCR repertoires of effector memory CD8+ T cells (CD8+ EM cells) and naive CD8+ T cells (CD8+ N cells) in the decidua and peripheral blood of women with normal or complicated pregnancy and examined PD-1 expression at a single-cell level to verify whether antigen-specific CD8+ T cells accumulate in the decidua and to identify immunological differences related to the suppression of antigen-specific CD8+ T cells between normal pregnancy, miscarriage, and preeclampsia. We observed that some TCRβ repertoires, which might recognize fetal or placental antigens, were clonally expanded. The population size of clonally expanded CD8+ EM cells was higher in the decidua than in the peripheral blood. CD8+ EM cells began to express PD-1 during the course of normal pregnancy. We found that the total proportion of decidual CD8+ EM cells not expressing PD-1 was increased both in miscarriage and in preeclampsia cases, although a different mechanism was responsible for this increase. The amount of cytotoxic CD8+ EM cells increased in cases of miscarriage, whereas the expression of PD-1 in clonally expanded CD8+ EM cells was downregulated in preeclampsia cases. These results demonstrated that decidual CD8+ EM cells were able to recognize fetal-specific antigens at the feto-maternal interface and could easily induce fetal rejection.

Abstract
RESEARCH QUESTION To evaluate pre-existing comorbidities, obstetric risk factors and adverse obstetric and neonatal outcomes in pregnancies conceived by oocyte donation, compared with naturally conceived pregnancies or by conventional IVF/intracytoplasmic sperm injection (IVF/ICSI). DESIGN This retrospective single-centre contemporary cohort study reviewed data from singleton deliveries at the University Hospital of Careggi, Florence, from 2009 to 2017. Maternal and perinatal outcomes were analysed. RESULTS The study included 25,851 pregnancies and newborns: 276 (1.1%) children were conceived after oocyte donation, 925 (3.6%) after IVF/ICSI and 24,650 (95.4%) after natural conception. Women in the oocyte donation group were significantly older compared with IVF/ICSI and natural conception groups (P < 0.0001) and had a higher prevalence of chronic hypertension compared with the natural conception group (P = 0.0090). They were administered anticoagulant medications more frequently during pregnancy. The incidence of gestational hypertension was significantly higher than in natural conception (aOR 3.6) and IVF/ICSI pregnancies (aOR 2.7). The incidence of Caesarean section in oocyte donation pregnancies was higher than in natural conception and IVF/ICSI groups (aOR 3.4 and 2.3, respectively). An 11-fold increased risk of post-partum haemorrhage (PPH) was found in oocyte donation versus natural conception and an almost four-fold increased risk was found in oocyte donation versus IVF/ICSI; prematurity and low birthweight were more frequent after oocyte donation versus natural conception (aOR 2.4 and 1.8, respectively). CONCLUSIONS Patients undergoing oocyte donation represent a group with increased comorbidities and risk factors for adverse obstetric outcomes. Oocyte donation seems to be independently associated with gestational hypertension and PPH. Pregnancies after oocyte donation warrant clinical surveillance with proper screening and, possibly, preventive strategies.

Abstract
Objectives: Oocyte donation pregnancies are more frequently complicated by preeclampsia (PE), which cause significant fetal-maternal morbidity and mortality. Our objective was to determine risk factors for PE in oocyte recipients (OR). Our secondary objective was to describe the course of pregnancy and the neonatal outcome in this group. Methods: This was a historical-prospective study. One hundred and fifty OR who gave birth to children at over 22 weeks of amenorrhea between January 2010 and June 2018 were included in the study. Results: Risk factors for PE in OR found in univariate analysis were as follows: primiparity, primipaternity, body mass index (BMI), and anti-Müllerian hormone (AMH) of the OR and age and AMH of the oocyte donors (OD). In multivariate analysis, the BMI of the OR (odds ratio [OR]: 1.2, 95% confidence interval [CI]: [1.1–1.4], P = 0.0474) and the AMH of the OD (OR: 1.2, 95% CI: [1.2–1.4], P = 0.0481) were found to be statistically significant risk factors for PE. In addition, we observed an increase in the rate of prematurity in the OR that were not associated with fetal growth retardation, despite the occurrence of PE. Conclusion: In OR, the allogeneic nature of pregnancy induces an increased risk of PE, the pathophysiology of which seems different from that in other methods of conception. Thus, risk factors for PE should be reconsidered to take into account the impact of certain characteristics of OD such as age and AMH.

Abstract
RESEARCH QUESTION In women with singleton pregnancies conceived after assisted reproductive technologies, does the in vitro fertilization with oocyte donation (IVF-OD) affect the perinatal and maternal outcomes compared to autologous in vitro fertilization (IVF-AO)? DESIGN Systematic review and meta-analysis of studies comparing perinatal and maternal outcomes in singleton pregnancies resulting from IVF-OD versus IVF-AO. An electronic literature search in Pubmed, MEDLINE, and Cochrane database was performed. The main outcome measures were hypertensive disorders in pregnancy, preeclampsia, severe preeclampsia, pregnancy-induced hypertension, preterm birth, early preterm birth, low birth weight, and very low birth weight. RESULTS Twenty-three studies were included. IVF-OD is associated with a higher risk of hypertensive disorders in pregnancy (OR 2.63, 2.17-3.18), preeclampsia (OR 2.64; 2.29-3.04), severe preeclampsia (OR 3.22; 2.30-4.49), pregnancy-induced hypertension (OR 2.16; 1.79-2.62), preterm birth (OR 1.57; 1.33-1.86), early preterm birth (OR 1.80; 1.51-2.15), low birth weight (OR 1.25, 1.20-1.30), very low birth weight (OR 1.37, 1.22-1.54), gestational diabetes (OR 1.27; 1.03-1.56), and cesarean section (OR 2.28; 2.14-2.42). There was no significant difference in the risk of preterm birth or low birth weight when adjusted for preeclampsia. CONCLUSIONS IVF-OD patients should be considered an independent risk factor for some adverse perinatal outcomes, mainly hypertensive disorders in pregnancy, preeclampsia, and severe preeclampsia. Immunological and hormonal aspects may be involved in these results, and further research focusing in the etiopathogenesis of these pathologies are needed.

Abstract
Pre‐eclampsia (PE) is a multisystem disorder that typically affects 2%–5% of pregnant women and is one of the leading causes of maternal and perinatal morbidity and mortality, especially when the condition is of early onset. Globally, 76 000 women and 500 000 babies die each year from this disorder. Furthermore, women in low‐resource countries are at a higher risk of developing PE compared with those in high‐resource countries.
Although a complete understanding of the pathogenesis of PE remains unclear, the current theory suggests a two‐stage process. The first stage is caused by shallow invasion of the trophoblast, resulting in inadequate remodeling of the spiral arteries. This is presumed to lead to the second stage, which involves the maternal response to endothelial dysfunction and imbalance between angiogenic and antiangiogenic factors, resulting in the clinical features of the disorder.
Accurate prediction and uniform prevention continue to elude us. The quest to effectively predict PE in the first trimester of pregnancy is fueled by the desire to identify women who are at high risk of developing PE, so that necessary measures can be initiated early enough to improve placentation and thus prevent or at least reduce the frequency of its occurrence. Furthermore, identification of an “at risk” group will allow tailored prenatal surveillance to anticipate and recognize the onset of the clinical syndrome and manage it promptly.
PE has been previously defined as the onset of hypertension accompanied by significant proteinuria after 20 weeks of gestation. Recently, the definition of PE has been broadened. Now the internationally agreed definition of PE is the one proposed by the International Society for the Study of Hypertension in Pregnancy (ISSHP).
According to the ISSHP, PE is defined as systolic blood pressure at ≥140 mm Hg and/or diastolic blood pressure at ≥90 mm Hg on at least two occasions measured 4 hours apart in previously normotensive women and is accompanied by one or more of the following new‐onset conditions at or after 20 weeks of gestation:
1.Proteinuria (i.e. ≥30 mg/mol protein:creatinine ratio; ≥300 mg/24 hour; or ≥2 + dipstick);
2.Evidence of other maternal organ dysfunction, including: acute kidney injury (creatinine ≥90 μmol/L; 1 mg/dL); liver involvement (elevated transaminases, e.g. alanine aminotransferase or aspartate aminotransferase >40 IU/L) with or without right upper quadrant or epigastric abdominal pain; neurological complications (e.g. eclampsia, altered mental status, blindness, stroke, clonus, severe headaches, and persistent visual scotomata); or hematological complications (thrombocytopenia–platelet count <150 000/μL, disseminated intravascular coagulation, hemolysis); or
3.Uteroplacental dysfunction (such as fetal growth restriction, abnormal umbilical artery Doppler waveform analysis, or stillbirth).
It is well established that a number of maternal risk factors are associated with the development of PE: advanced maternal age; nulliparity; previous history of PE; short and long interpregnancy interval; use of assisted reproductive technologies; family history of PE; obesity; Afro‐Caribbean and South Asian racial origin; co‐morbid medical conditions including hyperglycemia in pregnancy; pre‐existing chronic hypertension; renal disease; and autoimmune diseases, such as systemic lupus erythematosus and antiphospholipid syndrome. These risk factors have been described by various professional organizations for the identification of women at risk of PE; however, this approach to screening is inadequate for effective prediction of PE.
PE can be subclassified into:
1.Early‐onset PE (with delivery at <34+0 weeks of gestation);
2.Preterm PE (with delivery at <37+0 weeks of gestation);
3.Late‐onset PE (with delivery at ≥34+0 weeks of gestation);
4.Term PE (with delivery at ≥37+0 weeks of gestation).
These subclassifications are not mutually exclusive. Early‐onset PE is associated with a much higher risk of short‐ and long‐term maternal and perinatal morbidity and mortality.
Obstetricians managing women with preterm PE are faced with the challenge of balancing the need to achieve fetal maturation in utero with the risks to the mother and fetus of continuing the pregnancy longer. These risks include progression to eclampsia, development of placental abruption and HELLP (hemolysis, elevated liver enzyme, low platelet) syndrome. On the other hand, preterm delivery is associated with higher infant mortality rates and increased morbidity resulting from small for gestational age (SGA), thrombocytopenia, bronchopulmonary dysplasia, cerebral palsy, and an increased risk of various chronic diseases in adult life, particularly type 2 diabetes, cardiovascular disease, and obesity. Women who have experienced PE may also face additional health problems in later life, as the condition is associated with an increased risk of death from future cardiovascular disease, hypertension, stroke, renal impairment, metabolic syndrome, and diabetes. The life expectancy of women who developed preterm PE is reduced on average by 10 years. There is also significant impact on the infants in the long term, such as increased risks of insulin resistance, diabetes mellitus, coronary artery disease, and hypertension in infants born to pre‐eclamptic women.
The International Federation of Gynecology and Obstetrics (FIGO) brought together international experts to discuss and evaluate current knowledge on PE and develop a document to frame the issues and suggest key actions to address the health burden posed by PE.
FIGO's objectives, as outlined in this document, are: (1) To raise awareness of the links between PE and poor maternal and perinatal outcomes, as well as to the future health risks to mother and offspring, and demand a clearly defined global health agenda to tackle this issue; and (2) To create a consensus document that provides guidance for the first‐trimester screening and prevention of preterm PE, and to disseminate and encourage its use.
Based on high‐quality evidence, the document outlines current global standards for the first‐trimester screening and prevention of preterm PE, which is in line with FIGO good clinical practice advice on first trimester screening and prevention of pre‐eclampsia in singleton pregnancy.1
It provides both the best and the most pragmatic recommendations according to the level of acceptability, feasibility, and ease of implementation that have the potential to produce the most significant impact in different resource settings. Suggestions are provided for a variety of different regional and resource settings based on their financial, human, and infrastructure resources, as well as for research priorities to bridge the current knowledge and evidence gap.
To deal with the issue of PE, FIGO recommends the following:
Public health focus: There should be greater international attention given to PE and to the links between maternal health and noncommunicable diseases (NCDs) on the Sustainable Developmental Goals agenda. Public health measures to increase awareness, access, affordability, and acceptance of preconception counselling, and prenatal and postnatal services for women of reproductive age should be prioritized. Greater efforts are required to raise awareness of the benefits of early prenatal visits targeted at reproductive‐aged women, particularly in low‐resource countries.
Universal screening: All pregnant women should be screened for preterm PE during early pregnancy by the first‐trimester combined test with maternal risk factors and biomarkers as a one‐step procedure. The risk calculator is available free of charge at https://fetalmedicine.org/research/assess/preeclampsia. FIGO encourages all countries and its member associations to adopt and promote strategies to ensure this. The best combined test is one that includes maternal risk factors, measurements of mean arterial pressure (MAP), serum placental growth factor (PLGF), and uterine artery pulsatility index (UTPI). Where it is not possible to measure PLGF and/or UTPI, the baseline screening test should be a combination of maternal risk factors with MAP, and not maternal risk factors alone. If maternal serum pregnancy‐associated plasma protein A (PAPP‐A) is measured for routine first‐trimester screening for fetal aneuploidies, the result can be included for PE risk assessment. Variations to the full combined test would lead to a reduction in the performance screening. A woman is considered high risk when the risk is 1 in 100 or more based on the first‐trimester combined test with maternal risk factors, MAP, PLGF, and UTPI.
Contingent screening: Where resources are limited, routine screening for preterm PE by maternal factors and MAP in all pregnancies and reserving measurements of PLGF and UTPI for a subgroup of the population (selected on the basis of the risk derived from screening by maternal factors and MAP) can be considered.
Prophylactic measures: Following first‐trimester screening for preterm PE, women identified at high risk should receive aspirin prophylaxis commencing at 11–14+6 weeks of gestation at a dose of ~150 mg to be taken every night until 36 weeks of gestation, when delivery occurs, or when PE is diagnosed. Low‐dose aspirin should not be prescribed to all pregnant women. In women with low calcium intake (<800 mg/d), either calcium replacement (≤1 g elemental calcium/d) or calcium supplementation (1.5–2 g elemental calcium/d) may reduce the burden of both early‐ and late‐onset PE.

Abstract
Soluble HLA-G (sHLA-G) levels in human seminal plasma (SP) can be diverse and may affect the establishment of maternal-fetal tolerance and thereby the outcome of pregnancy. We investigated whether sHLA-G levels in SP are associated with polymorphisms in the 3'-untranslated region (UTR) and UTR haplotypes of the HLA-G gene. Furthermore, we compared the HLA-G genotype distribution and sHLA-G levels between men, whose partner experienced unexplained recurrent miscarriage (RM), and controls. Soluble HLA-G levels (n = 156) and HLA-G genotyping (n = 176) were determined in SP samples. The concentration of sHLA-G was significantly associated with several single-nucleotide polymorphisms (SNPs): the 14 base pair (bp) insertion/deletion (indel), +3010, +3142, +3187, +3196, and + 3509. High levels of sHLA-G were associated with UTR-1 and low levels with UTR-2, UTR-4, and UTR-7 (P < .0001). HLA-G genotype distribution and sHLA-G levels in SP were not significantly different between the RM group (n = 44) and controls (n = 31). In conclusion, seminal sHLA-G levels are associated with both singular SNPs and 3UTR haplotypes. HLA-G genotype and sHLA-G levels in SP are not different between men whose partner experienced RM and controls, indicating that miscarriages are not solely the result of low sHLA-G levels in SP. Instead, it is more likely that these miscarriages are the result of a multifactorial immunologic mechanism, whereby the HLA-G 3'UTR 14 bp ins/ins genotype plays a role in a proportion of the cases. Future studies should look into the functions of sHLA-G in SP and the consequences of low or high levels on the chance to conceive.

Abstract
PURPOSE To explore associations between infertility treatment and hypertensive disorders of pregnancy. METHODS We collated multi-year as well as multi-state data from a national representative survey examining the association between self-reported infertility treatment (i.e., medication, intrauterine insemination, or assisted reproductive technology) and hypertensive disorders of pregnancy (i.e., high blood pressure, pregnancy-induced hypertension (PIH), preeclampsia, and toxemia). Data were analyzed using logistic regression. A total of 21,884 women in the United States (U.S.), from the Centers for Disease Control and Prevention's (CDC) Pregnancy Risk Assessment Monitoring System (PRAMS) survey (2009-2015), participated in the study. RESULTS In our analysis, 12.91% women reported a history of infertility treatment and 15.19% reported a history of hypertensive disorder of pregnancy. Compared with women who had never had infertility treatment, women who reported infertility treatment had 1.18 (adjusted OR, 95% confidence interval (CI) 1.05, 1.33) higher odds of reporting hypertensive disorder of pregnancy. Neither types of infertility treatment nor proximity of treatment to pregnancy were independently associated with hypertensive disorder of pregnancy. CONCLUSIONS Our results suggest that among U.S. women, the treatment of infertility may be associated with hypertension disorder of pregnancy regardless of type of treatment.

Abstract
INTRODUCTION Turner syndrome is one of the most frequent chromosomal abnormalities in women, with a prevalence estimated to be 1 of 2500 live birth. Pregnancy in women with Turner syndrome is known to be at high risk, whether it is spontaneous or after oocyte donation, because of miscarriages and potential cardio-vascular complications which can be life-threatening. All of these patients should therefore be screened with a comprehensive cardio-vascular assessment before pregnancy, and have a close follow-up during and after pregnancy. PATIENTS AND METHODS It is a retrospective study, conducted in 10 of the 27 French oocyte donation centers between 2012 and 2016, on all the patients presenting with Turner syndrome included in an oocyte donation program. RESULTS 151 embryo transfers were realized in 73 patients, resulting in 39 pregnancies. Among these pregnancies, 24 children were born healthy, 11 spontaneous miscarriages, 3 voluntary abortions, 1 extra-uterine pregnancy and 1 maternal death from non-cardio-vascular origin occurred. Pregnancies were complicated by gravid arterial hypertension in 28.2% of cases, preeclampsia in 10.3% of cases, and gestational diabetes in 7.7% of cases. CONCLUSION This study bring out obstetrical complications of the same magnitude than the ones described in the literature. Lead over a period of 4 years, in 10 French oocyte donation centers, it doesn't reveal any cardio-vascular complications, conversely to other studies published before French and American recommendations. This study reinforces the usefulness of specific recommendations for the care of these particular patients.

Abstract
Autophagy is an evolutionarily conserved process in eukaryotes to maintain cellular homeostasis under environmental stress. Intracellular control is exerted to produce energy or maintain intracellular protein quality controls. Autophagy plays an important role in embryogenesis, implantation, and maintenance of pregnancy. This role includes supporting extravillous trophoblasts (EVTs) that invade the decidua (endometrium) until the first third of uterine myometrium and migrate along the lumina of spiral arterioles under hypoxic and low-nutrient conditions in early pregnancy. In addition, autophagy inhibition has been linked to poor placentation—a feature of preeclamptic placentas—in a placenta-specific autophagy knockout mouse model. Studies of autophagy in human placentas have revealed controversial results, especially with regard to preeclampsia and gestational diabetes mellitus (GDM). Without precise estimation of autophagy flux, wrong interpretation would lead to fixed tissues. This paper presents a review of the role of autophagy in pregnancy and elaborates on the interpretation of autophagy in human placental tissues.

Abstract
Background The objective of this systematic review and meta-analyses was to assess the risk of preeclampsia among women who conceived with assisted reproductive technology (ART). Methods We searched the ISI Web of Knowledge, Medline/PubMed, Scopus, and Embase (from inception to May 2017) for English language articles using a list of key words. In addition, reference lists from identified studies and relevant review articles were also searched. Data extraction was performed by two authors, and the study quality was assessed using the Newcastle–Ottawa Scale. Random-effects model meta-analysis was applied to pool the relative risks (RR) across studies. Results A total of 48 studies (5 case-control studies and 43 cohort studies) were included in this meta-analysis. The Cochran Q test and I2 statistics revealed substantial heterogeneity (Q = 26,313.92, d.f. = 47, p < 0.001 and I2 = 99.8%). Meta-analysis showed a significant increase in preeclampsia in women who conceived by ART compared with those who conceived spontaneously (RR = 1.71, 95% CI = 1.11–2.62, p = 0.015). Conclusions The findings of this systematic review indicate that the use of ART treatment is associated with a 1.71-fold increase in preeclampsia.

Abstract
Semi-allogenic fetuses are not rejected by the maternal immune system because feto-maternal tolerance induced by CD4+CD25+FoxP3+ regulatory T (Treg) cells is established during pregnancy. Paternal antigen-specific Treg cells accumulate during pregnancy, and seminal plasma priming plays an important role in expanding paternal antigen-specific Treg cells in mouse models. Although paternal-antigen specific Treg cells have not been identified in humans, recent studies suggest that antigen-specific Treg cells exist and expand at the feto-maternal interface in humans. Studies have also revealed that reduction of decidual functional Treg cells occurs during miscarriage with normal fetal chromosomal content, whereas insufficient clonal expansion of decidual Treg cells is observed in preeclampsia. In this review, we will discuss the recent advances in the investigation of mechanisms underlying Treg cell-dependent maintenance of feto-maternal tolerance.

Abstract
Objective: Previous studies have indicated that women with assisted reproductive technology (ART) pregnancy have an increased risk of preeclampsia. The aim of this current study was to estimate, through a systematic review and meta-analysis of cohort studies, the risk of preeclampsia in women who conceived with ART.Materials and methods: We searched ISI Web of Knowledge, Medline/PubMed, Scopus and Embase up to August 2017 for English-language articles pertaining to risk of preeclampsia in ART pregnancy using standard keywords. Data extraction was conducted by two authors and quality of the studies was assessed using the Newcastle-Ottawa Scale. A random-effects model was used for the meta-analysis.Results: In total, 72 cohort studies (n = 164 870) were included. The results of Cochran test and I2 statistic indicated considerable heterogeneity among studies (Q = 15 415.61, df = 71, p < .001, I2=99.5%). The pooled estimate of preeclampsia risk using the random effects model was 10.8% (95% CI: 9.10-12.5). Furthermore, the funnel plot and Begg's test showed evidence of publication bias.Conclusions: We found that the risk of preeclampsia was very high among women who conceived with ART. Women should be counseled carefully before undergoing ART treatment.

Abstract
Preeclampsia is a condition associated with high rates of maternal-fetal morbidity and mortality. It usually occurs in 3–10% of nulliparous women and 18% of previously affected women. Different lines of evidence have demonstrated the role of the father in the onset of preeclampsia. The placenta is the cornerstone of preeclampsia and poses important paternal genetic determinants; in fact, the existence of a “paternal antigen” has been proposed. Nulliparity is a well-known risk factor. Change of partner to a woman without history of preeclampsia increases the risk; however, this change decreases in women with history of the condition. High interval between pregnancies, short sexual intercourse before pregnancy, and conception by intracytoplasmic sperm injection suggest a limited exposure to the so-called paternal antigen. A man who was born from a mother with preeclampsia also increases the risk to his partner. Not only maternal but also paternal obesity is a risk factor for preeclampsia. Fetal HLA-G variants from the father increased the immune incompatibility with the mother and are also significantly associated with preeclampsia in multigravida pregnancies. An analysis of a group of Swedish pregnant women showed that the risk for preeclampsia is attributable to paternal factors in 13% of cases, which could be related to genetic interactions with maternal genetic factors. This review aimed to evaluate the evidences of the father’s contribution to the onset of preeclampsia and determine the importance of including them in future studies.

Abstract
INTRODUCTION Pregnancies after gamete donation are at higher risk of developing pre-eclampsia (PE) than those achieved by IVF with patient's own gametes. We aim to assess whether pregnancies achieved with both oocyte and sperm donation (double donation, DD) are at an increased risk of developing PE and gestational hypertension (GH) compared to those achieved by oocyte donation alone (OD). MATERIALS AND METHODS Retrospective cohort study of 433 patients who reached the 20th week of gestation with either DD (n = 81) or OD (n = 352) between March 2013 and April 2016 at a fertility clinic. The risk of preterm PE, term PE, and gestational hypertension (GH) are presented as unadjusted and adjusted odds ratio (OR). RESULTS DD have a higher risk of preterm PE than OD, with an OR of 3.02 (95%CI 1.11-8.24; p = 0.031). We found no difference in the risk of term PE (OR 0.26, 95%CI 0.03-1.98; p = 0.19) or of GH (OR 1.23, 95% CI 0.63-2.43; p = 0.55). DISCUSSION Pregnancies with DD are at higher risk of developing preterm PE than OD alone. Patients, and physicians treating them, should be made aware of the elevated risk of PE in these gestations, in order to start prophylactic measures during the first weeks of pregnancy.

Abstract
Objective Preeclampsia (PE) occurs in 4.6% of pregnancies worldwide. The social
phenomenon of increasing maternal age has raised the demand for donor
oocytes. Egg donation has allowed women with poor ovarian reserve, premature
ovarian failure, genetic disorders or surgical menopause to get pregnant.
Recipients provide a unique model of immune response because of the
differences in the genetic makeup of mothers and fetuses. In PE, immune
tolerance may be impaired as a result of having non-autologous eggs
implanted. Egg donation is a highly successful assisted reproductive
technology, despite the significant number of issues arising from the
implantation of non-autologous eggs. This study aimed to determine whether
there is an association between egg donation and preeclampsia. Methods A systematic review of the literature available in PubMed and Google Scholar
was carried out from January of 1995 to August of 2016 using the terms
'oocyte donation, preeclampsia', 'oocyte donation, in vitro
fertilization, preeclampsia', 'oocyte donation, preeclampsia, outcomes
pregnancies', 'oocyte donation, obstetric outcome.' Only six retrospective
cohort studies met the selection criteria. Result The meta-analysis revealed a statistically significant association between
egg donation and onset of preeclampsia (OR 4.50; 95% CI: 3.28-6.19;
p<0.0001). Conclusion Oocyte donation is associated with increased risk of preeclampsia in
singleton pregnancies. Therefore, it is crucial to properly record and
assess this finding when egg donation is the chosen assisted reproductive
technology to attain pregnancy.

Abstract
Although it is widely considered, in many cases, to involve two separable stages (poor placentation followed by oxidative stress/inflammation), the precise originating causes of preeclampsia (PE) remain elusive. We have previously brought together some of the considerable evidence that a (dormant) microbial component is commonly a significant part of its etiology. However, apart from recognizing, consistent with this view, that the many inflammatory markers of PE are also increased in infection, we had little to say about immunity, whether innate or adaptive. In addition, we focused on the gut, oral and female urinary tract microbiomes as the main sources of the infection. We here marshall further evidence for an infectious component in PE, focusing on the immunological tolerance characteristic of pregnancy, and the well-established fact that increased exposure to the father's semen assists this immunological tolerance. As well as these benefits, however, semen is not sterile, microbial tolerance mechanisms may exist, and we also review the evidence that semen may be responsible for inoculating the developing conceptus (and maybe the placenta) with microbes, not all of which are benign. It is suggested that when they are not, this may be a significant cause of PE. A variety of epidemiological and other evidence is entirely consistent with this, not least correlations between semen infection, infertility and PE. Our view also leads to a series of other, testable predictions. Overall, we argue for a significant paternal role in the development of PE through microbial infection of the mother via insemination.

Abstract
Aims: The aim of this study is to evaluate and compare multiple obstetric and perinatal outcomes between donor-oocyte in vitro fertilization (IVF) and self-oocyte IVF group. Settings and Design: This study was done in a tertiary care center with ART unit. This was a retrospective comparative cohort study. Materials and Methods: The present study comprised all women between 20 and 45 years who conceived from oocyte donation (n = 78) between December 1, 2010, and December 31, 2016, and compared with all women who underwent self-oocyte IVF (n = 112). The process involved controlled ovarian stimulation and retrieval of the donor oocytes, preparation of recipient endometrium, and pregnancy management. Obstetric and perinatal outcomes were compared. Statistical Analysis Used: Chi-square test was used for categorical variables. Analysis for confounding variables was performed using multivariable linear and logistic regression analysis. Results: Baseline characteristics between the two groups were comparable. Miscarriage, first-trimester bleeding, pregnancy-induced hypertension (PIH), and gestational diabetes mellitus were significantly higher in donor-oocyte IVF group compared to self-oocyte cycles (P = 0.001). Using multiple logistic regression analysis, age class adjusted PIH incidence was significantly higher in donor-oocyte group as compared to self-oocyte group (P = 0.010). There was no significant variation in perinatal outcomes between the donor- and self-oocyte IVF cycles (P > 0.05). Conclusion: Oocyte donation should be treated as an independent risk factor for PIH.

Abstract
In the literature, there is growing evidence that subfertile patients who conceived after infertility treatments have an increased risk of pregnancy and perinatal complications and this is particularly true for patients who conceived through use of high technology infertility treatments. Moreover, high technology infertility treatments include many concomitant clinical and biological risk factors. This review aims to summarize in a systematic fashion the current evidence regarding the relative effect of the different procedures for high technology infertility treatments on the risk of adverse pregnancy and perinatal outcome. A literature search up to August 2016 was performed in IBSS, SocINDEX, Institute for Scientific Information, PubMed, Web of Science and Google Scholar and an evidence-based hierarchy was used to determine which articles to include and analyze. Data on prepregnancy maternal factors, low technology interventions, specific procedures for male factor, ovarian tissue/ovary and uterus transplantation, and chromosomal abnormalities and malformations of the offspring were excluded. The available evidences were analyzed assessing the level and the quality of evidence according to the Oxford Centre for Evidence-Based Medicine guidelines and the Grading of Recommendations Assessment, Development, and Evaluation system, respectively. Current review highlights that every single procedure of high technology infertility treatments can play a crucial role in increasing the risk of pregnancy and perinatal complications. Due to the suboptimal level and quality of the current evidence, further well-designed studies are needed.

Abstract
PURPOSE The objective of this study was to evaluate the effect of changing fertility status on perinatal outcomes of singleton siblings, conceived with and without assisted reproductive technology (ART). METHOD A longitudinal cohort study of Massachusetts resident women having two consecutive singleton births during 2004-2010 was performed. Women were classified as ART (A), subfertile (S), or fertile (F) and categorized by their fertility status in each birth as A-A, A-S, S-A, S-S, F-A, F-S, and F-F. Within categories, adjusted mean birthweights, gestations, and birthweight Z scores were estimated with linear generalized estimating equations. Risks of low birthweight (LBW, <2500 g), preterm birth (PTB, <37 weeks), and placental complications were modeled using logistic regression by fertility status as adjusted odds ratios (AORs) and 95 % confidence intervals (CIs). RESULTS Birthweights in second pregnancies averaged 74-155 g higher, except for births to F-A women, who averaged -16 g lower. Most women had a reduction in length of gestation in their second pregnancies, with F-A women having the largest decline (-0.5 weeks). In first birth models, the risks for LBW and placental complications were increased for subfertile (AOR 1.39 [1.07-1.81] and 1.97 [1.33-2.93], respectively) and ART women (AOR 1.58 [1.29-1.93] and 3.40 [2.64-4.37], respectively). Second birth models showed increased risks for ART births of LBW (AOR 3.13 [2.19-4.48]) and placental complications (AOR 2.45 [1.56-3.86]) and greater risks of PTB for both ART (AOR 2.37 [1.74-3.23]) and subfertile women (AOR 1.47 [1.02-2.13]). CONCLUSIONS Declining fertility status, with and without assisted reproductive technology treatment, is associated with increasing risks for adverse outcomes, greatest for women whose fertility status declined the most.

Abstract
Although the use of donor sperm as a treatment modality for male infertility has become common place, the health outcomes for those conceived has been poorly studied. A structured search of the literature using PubMed, EMBASE and Cochrane Reviews was performed to investigate the health outcomes of offspring conceived from donor sperm. Eight studies were eligible and included in the review, and of these, three were included in a meta-analysis. Meta-analysis of clinical outcomes showed that donor sperm neonates are not at increased risk of being born of low birth weight (<2500 g), preterm (<37 weeks) or with increased incidences of birth defects, than spontaneously conceived neonates.

Abstract
Seminal fluid is often viewed as simply a vehicle to carry sperm to fertilize the oocyte, but a more complex function in influencing female reproductive physiology is now evident. Remarkably, seminal fluid contains soluble and exosome-born signaling agents that interact with the female reproductive tract to prime the immune response, with consequences for fertility and pregnancy outcome. Experiments in rodent models demonstrate a key role for seminal fluid in enabling robust embryo implantation and optimal placental development. In particular, seminal fluid promotes leukocyte recruitment and generation of regulatory T cells, which facilitate embryo implantation by suppressing inflammation, assisting uterine vascular adaptation, and sustaining tolerance of fetal antigens. There is emerging evidence of comparable effects in women, where seminal fluid provokes an adaptive immune response in the cervical tissues after contact at intercourse, and spermatozoa accessing the higher tract potentially affect the endometrium directly. These biological responses may have clinical significance, explaining why [1] intercourse in IVF ET cycles improves the likelihood of pregnancy, [2] inflammatory disorders of gestation are more common in women who conceive after limited exposure to seminal fluid of the prospective father, and [3] preeclampsia incidence is elevated after use of donor oocytes or donor sperm where prior contact with conceptus alloantigens has not occurred. It will be important to define the mechanisms through which seminal fluid interacts with female reproductive tissues, to provide knowledge that may assist in preconception planning and infertility treatment.

Abstract
BACKGROUND Important roles for G-protein-coupled receptors (GPCRs) have been identified in the maternal physiological adaptations to pregnancy and in the pathogenesis of preeclampsia. On this basis, GPCRs are potential therapeutic targets for preeclampsia. OBJECTIVES AND RATIONALE In this review, vasopressin and apelin are initially considered in this context before the focus on the hormone relaxin and its cognate receptor, the relaxin/insulin-like family peptide receptor 1 (RXFP1). Based on both compelling scientific rationale and a promising safety profile, the relaxin ligand-receptor system is comprehensively evaluated as a potential therapeutic endpoint in preeclampsia. SEARCH METHODS The published literature relating to the topic was searched through January 2016 using PubMed. OUTCOMES Relaxin is a peptide hormone secreted by the corpus luteum; it circulates in the luteal phase and during pregnancy. Activation of RXFP1 is vasodilatory; thus, relaxin supplementation is expected to at least partly restore the fundamental vasodilatory changes of normal pregnancy, thereby alleviating maternal organ hypoperfusion, which is a major pathogenic manifestation of severe preeclampsia. Specifically, by exploiting its pleiotropic hemodynamic attributes in preeclampsia, relaxin administration is predicted to (i) reverse robust arterial myogenic constriction; (ii) blunt systemic and renal vasoconstriction in response to activation of the angiotensin II receptor, type 1; (iii) mollify the action of endogenous vasoconstrictors on uterine spiral arteries with failed remodeling and retained smooth muscle; (iv) increase arterial compliance; (v) enhance insulin-mediated glucose disposal by promoting skeletal muscle vasodilation and (vi) mobilize and activate bone marrow-derived angiogenic progenitor cells, thereby repairing injured endothelium and improving maternal vascularity in organs such as breast, uterus, pancreas, skin and fat. By exploiting its pleiotropic molecular attributes in preeclampsia, relaxin supplementation is expected to (i) enhance endothelial nitric oxide synthesis and bioactivity, as well as directly reduce vascular smooth muscle cytosolic calcium, thus promoting vasodilation; (ii) improve the local angiogenic balance by augmenting arterial vascular endothelial and placental growth factor (VEGF and PLGF) activities; (iii) ameliorate vascular inflammation; (iv) enhance placental peroxisome proliferator-activated receptor gamma, coactivator 1 alpha (PCG1α) expression, and hence, peroxisome proliferator-activated receptor gamma (PPAR-γ) activity and (v) confer cytotrophoblast and endothelial cytoprotection. Insofar as impaired endometrial maturation (decidualization) predisposes to the development of preeclampsia, relaxin administration in the late secretory phase and during early pregnancy would be anticipated to improve decidualization, and hence trophoblast invasion and spiral artery remodeling, thereby reducing the risk of preeclampsia. Relaxin has a favorable safety profile both in the non-pregnant condition and during pregnancy. WIDER IMPLICATIONS There is a strong scientific rationale for RXFP1 activation in severe preeclampsia by administration of relaxin, relaxin analogs or small molecule mimetics, in order to mollify the disease pathogenesis for safe prolongation of pregnancy, thus allowing time for more complete fetal maturation, which is a primary therapeutic endpoint in treating the disease. In light of recent data implicating deficient or defective decidualization as a potential etiological factor in preeclampsia and the capacity of relaxin to promote endometrial maturation, the prophylactic application of relaxin to reduce the risk of preeclampsia is a plausible therapeutic approach to consider. Finally, given its pleiotropic and beneficial attributes particularly in the cardiovascular system, relaxin, although traditionally considered as a 'pregnancy' hormone, is likely to prove salutary for several disease indications in the non-pregnant population.
