Abstract
BACKGROUND Women's reproductive health is associated with cardiovascular morbidity. However, an association of vaginal bleeding (VB) in pregnancy with diabetes and cardiovascular outcomes has scarcely been investigated. METHODS We conducted a population-based cohort study in Denmark (1994-2018). Using nationwide registries, among 903 327 women we identified 1 901 725 pregnancies: 39 265 ended in childbirth and were affected by VB; 1 389 285 ended in childbirth and were unaffected by VB; 333 785 ended in a termination, and 139 390 ended in a miscarriage. The outcomes were diabetes types 1 and 2, hypertension, ischaemic heart disease including myocardial infarction, atrial fibrillation or flutter, heart failure and ischaemic and haemorrhagic stroke. We computed incidence rates and hazard ratios (HRs) with 95% confidence intervals (CIs) adjusted for age, calendar year of pregnancy end, morbidities and reproductive and socioeconomic factors, using inverse probability of treatment-weighted Cox proportional hazards regression. RESULTS In analyses of VB-affected vs VB-unaffected pregnancies, aHRs were 1.15 (1.03-1.28) for diabetes type 1, 1.19 (1.13-1.26) for diabetes type 2, 1.19 (1.14-1.25) for hypertension, 1.26 (1.16-1.37) for ischaemic heart disease, 1.21 (1.03-1.42) for myocardial infarction, 1.32 (1.14-1.51) for atrial fibrillation or flutter and 1.23 (0.99-1.52) for heart failure. aHRs were 1.41 (1.26-1.57) and 1.46 (1.23-1.72) for ischaemic and haemorrhagic stroke, respectively. When contrasting VB-affected pregnancies with terminations, aHRs were up to 1.3-fold increased for diabetes and hypertension; however, when contrasting VB-affected pregnancies with miscarriages, estimates were below or close to the null value. CONCLUSIONS Women's risks of diabetes and cardiovascular outcomes later in life were increased following VB-affected vs VB-unaffected pregnancy or termination, but not following VB-affected pregnancy vs miscarriage.

Front Pharmacol 2023; 14:1138968. [PMID: 37332346 PMCID: PMC10275364 DOI: 10.3389/fphar.2023.1138968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Accepted: 05/22/2023] [Indexed: 06/20/2023] Open
Abstract
Background: Despite some progress has been made in the pathogenesis and treatment of threatened miscarriage (TM), conventional treatment remains suboptimal. Thus, complementary medicine gradually become a new treatment option for treating threatened miscarriage. Gushen Antai Pills (GAP), a classic prescription of Traditional Chinese medicine (TCM), has became a popular complementary therapy to conventional western medicine (dydrogesterone) in treating threatened miscarriage in recent years. However, a systematic summary and analysis for its therapeutic effects is lacking. This meta-analysis aimed to systematically evaluate the effectiveness and safety of Gushen Antai Pills combined with dydrogesterone in the treatment of threatened miscarriage. Methods: A systematic search across seven electronic databases was conducted from inception to 17 September 2022. Studies were included if they were randomized controlled trials (RCTs) evaluating the effect of integrating Gushen Antai Pills and dydrogesterone in patients with threatened miscarriage, and reported the outcomes of interest. All statistical analyses were conducted using the Revman5.3 and Stata 13 software. The GRADE system was used to evaluate the quality of evidence. Results: Ten eligible randomized controlled trials involving 950 participants were contained in this meta-analysis. The pooled analysis showed that Gushen Antai Pills combined with dydrogesterone can significantly reduce the incidence of early pregnancy loss (RR: 0.29; 95% CI: 0.19-0.42; p < 0.00001) and alleviate clinical symptoms (RR: 1.39; 95% CI: 1.22-1.59; p < 0.00001), compared with treatment of dydrogesterone alone. Also, meta-analysis indicated that integrating Gushen Antai Pills and dydrogesterone is more effective than using dydrogesterone alone in improving hormone levels (serum levels of progesterone, β-HCG and estradiol) for women with threatened miscarriage (all p < 0.00001). Meanwhile, the combined effects with significant heterogeneity also showed favorable consistency in the sensitivity analyses, indicating a good stability of present results. Moreover, no significant differences between Gushen Antai Pills combined with dydrogesterone and control group on adverse events was identified. The overall GRADE qualities were low to moderate. Conclusion: The overall available evidence suggested that Gushen Antai Pills combined with dydrogesterone had significant effects in improving pregnancy success rate, clinical symptoms and hormone levels for women with threatened miscarriage, with considerable safety and reliability. However, due to the partial heterogeneity, suboptimal quality and high risk of bias of some included studies, further rigorously designed randomized controlled trials are required.

Abstract
OBJECTIVE To study differences in cytokine expression profiles between women with ongoing pregnancy and those experiencing spontaneous miscarriage, among women who presented with threatened miscarriage before week 16 of gestation. DESIGN Prospective cohort study. SETTING Academic hospital. PATIENT(S) In this prospective cohort study, 155 pregnant women, comprising normal pregnant women recruited from antenatal clinics (n = 97) and women with threatened miscarriage recruited from an emergency walk-in clinic (n = 58). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Sixty-five serum cytokines quantified using multiplex immunoassay correlated with miscarriage outcomes. RESULT(S) Among women presenting with threatened miscarriage, those who eventually miscarried had significantly lower levels of interleukin (IL)-2, IL-12p70, IL-17A, B-cell-activating factor, B lymphocyte chemoattractant, basic nerve growth factor, interferon-γ, tumor necrosis factor-related apoptosis-inducing ligand, thymic stromal lymphopoietin, and tumor necrosis factor-α and higher levels of vascular endothelial growth factor A, IL-21, and stromal cell-derived factor 1α than those with ongoing pregnancy. Comparisons between normal pregnancies and women with threatened miscarriage who eventually miscarried revealed significant differences across 7 cytokines: B-cell-activating factor; B lymphocyte chemoattractant; basic nerve growth factor; IL-17A; fractalkine/CX3CL1; vascular endothelial growth factor A; and CCL22. Vascular endothelial growth factor A exhibited a negative correlation with the progesterone level (r = -0.270). The cluster of significant cytokines alludes to T cell proliferation, B-cell proliferation, natural killer cell-mediated cytotoxicity, and apoptosis as important pathways that determine pregnancy outcomes. Bioinformatic analysis further revealed alteration of the suppressor of cytokine signaling proteins family of Janus kinase-signal transducer and activator of transcription signaling axis by cytokines as a plausible key molecular mechanism in spontaneous miscarriage. CONCLUSION(S) This study demonstrates that the regulated balance between the proinflammatory and anti-inflammatory pathways is crucial to maintaining pregnancy. A better understanding of the cytokines associated with immunomodulatory effects may lead to novel targets for the prediction and treatment of spontaneous miscarriage.

Abstract
Energy metabolism plays a crucial role in the immune system. In addition to providing vital energy for cell growth, reproduction and other cell activities, the metabolism of nutrients such as glucose and lipids also have significant effects on cell function through metabolites, metabolic enzymes, and changing metabolic status. Interleukin-10 (IL-10), as a pleiotropic regulator, can be secreted by a diverse set of cells and can also participate in regulating the functions of various cells, thereby playing an essential role in the formation and maintenance of immune tolerance in pregnancy. Studies on the regulatory effects and mechanisms of IL-10 on immune cells are extensive; however, research from a metabolic perspective is relatively negligible. Here, we have discussed old and new data on the relationship between IL-10 and metabolism. The data show that alterations in cellular metabolism and specific metabolites regulate IL-10 production of immune cells. Moreover, IL-10 regulates immune cell phenotypes and functions by modulating oxidative phosphorylation and glycolysis. This review summarizes some earlier observations regarding IL-10 and its relationship with immune cells in pregnancy, and also presents recent research on the link between IL-10 and metabolism, highlighting the potential relationship between IL-10, immune cells, and energy metabolism during pregnancy.

Abstract
BACKGROUND Pregnancies complicated by threatened miscarriage (TM) may be associated with adverse pregnancy outcomes. The objective of this study was to compare the differences in pregnancy outcomes between the women who experienced TM and asymptomatic controls. METHODS This was a 10-year retrospective review. Case records of 117 women who were managed for TM from January 1, 2010, to December 31, 2019, were retrieved and studied. The control group was developed from an equal number of asymptomatic clients matched for age, parity, and BMI who were receiving antenatal care (ANC) during the same period. Data on demography, clinical and ultrasound findings, treatment, and pregnancy outcomes were retrieved and analyzed. RESULTS Spontaneous abortion rate of 13.7% was recorded among the study group compared with 3.4% in the control (P-value [p] = 0.005, odds ratio [OR]: 4.475; 95% confidence interval [CI]: 1.445 - 13.827). Women with TM had higher odds for placenta previa (p = 0.049, OR: 4.77, 95% CI: 2.19 - 23.04), premature rupture of membranes (PROM) (p = 0.028, OR: 1.918, 95% CI: 1.419 - 2.592), postpartum hemorrhage (PPH) (p = 0.001, OR: 2.66, 95% CI: 20.8 - 8.94), and preterm birth (OR: 2.5, 95% CI: 1.75 - 3.65). They were also more likely to undergo cesarean section (p = 0.020, OR: 1.70, 95% CI: 1.053 - 2.964). There was no statistically significant difference in their infants' mean birth weight (3.113 ± 0.585kg for the TM group and 3.285± 0.536kg for the control, P=0.074). Other maternal and perinatal complications were similar. Admission for bed rest significantly improved fetal survival. Women who were not admitted for bed rest had higher odds of pregnancy loss (OR: 3.443, 95% CI: 1.701-7.99). Other treatment plans did not significantly contribute to a positive outcome. CONCLUSION Threatened miscarriage is a significant threat to fetal survival and may increase the risk for operative delivery. Bed rest improves the live birth rate.

Abstract
BACKGROUND The birth of a child affected by a threatened abortion (TAB) in utero is associated with autism spectrum disorder; association with other neurological disorders is unknown. METHODS This nationwide registry-based cohort study included singletons live-born in Denmark (1979-2010), followed through 2016. The outcomes were epilepsy, cerebral palsy (CP) and attention-deficit/hyperactivity disorder (ADHD). We used Cox regression to compute hazard ratios (HRs), adjusted for birth year, birth order, parental age, morbidity, medication use and maternal socio-economic factors. To remove time-invariant family-shared confounding, we applied sibling analyses. RESULTS The study population included 1 864 221 singletons live-born in 1979-2010. Among the TAB-affected children (N = 59 134) vs TAB-unaffected children, at the end of follow-up, the cumulative incidence was 2.2% vs 1.6% for epilepsy, 0.4% vs 0.2% for CP and 5.5% vs 4.2% for ADHD (for children born in 1995-2010). The adjusted HRs were 1.25 [95% confidence interval (CI) 1.16-1.34] for epilepsy, 1.42 (95% CI 1.20-1.68) for CP and 1.21 (95% CI 1.14-1.29) for ADHD. In the sibling design, the adjusted HRs were unity for epilepsy (full siblings: 0.96, 95% CI 0.82-1.12; maternal: 1.04, 95% CI 0.90-1.20; paternal: 1.08, 95% CI 0.93-1.25) and ADHD (full: 1.08, 95% CI 0.92-1.27; maternal: 1.04, 95% CI 0.90-1.20; paternal: 1.08, 95% CI 0.93-1.25). For CP, HRs shifted away from unity among sibling pairs (full: 2.92, 95% CI 1.33-6.39; maternal: 2.03, 95% CI 1.15-3.57; paternal: 3.28, 95% CI 1.36-7.91). CONCLUSIONS The birth of a child affected by TAB in utero was associated with a greater risk of CP, but not epilepsy or ADHD.

Abstract
OBJECTIVE To compare the changing peripheral levels of inflammation-related cytokine profile during a 9-day period after blastocyst transfer between women who did and did not conceive. DESIGN Prospective, observational, and longitudinal study. SETTING University-affiliated hospital. PATIENT(S) Forty-seven women with infertility who were undergoing single day-5 blastocyst transfer were recruited. INTERVENTION(S) This prospective observational and longitudinal study on 47 women with infertility was performed in an in vitro fertilization unit from December 2018 to August 2019. The amounts of a range of cytokines was measured on serial blood samples obtained during a 9-day period after blastocyst transfer. MAIN OUTCOME MEASURE(S) Serial blood samples were obtained on the day of embryo transfer, and 3, 6, and 9 days afterward for measurement of serum interferon gamma (IFN-γ), tumor necrosis factor alpha, interleukin (IL)-2, IL-4, IL-10, IL-12, IL-13, IL-17, IL-18, and IL-22 using cytometric bead arrays; transforming growth factor beta 1 (TGF-β1) was measured using commercial enzyme-linked immunosorbent assay kits. RESULT(S) The cytokine profile was similar between the women who conceived and those who did not on the day of blastocyst transfer. In women who conceived, IFN-γ and IL-17 (pro-inflammatory cytokines) exhibited a transient and significant increase on day 3 after blastocyst transfer, which decreased to the baseline levels by day 6. Meanwhile, IL-10 (anti-inflammatory cytokine) was increased significantly on days 6 and 9, and TGF-β1 (anti-inflammatory cytokine) was increased significantly on day 9 after blastocyst transfer. In women who did not conceive, there was a more pronounced increase in IFN-γ and IL-17 (pro-inflammatory cytokines) on day 3, which was sustained on days 6 and 9 without a switch to an anti-inflammatory cytokine profile. CONCLUSION(S) Among women who conceived after blastocyst embryo transfer, there was a transient and modest increase in serum pro-inflammatory cytokine profile (IFN-γ and IL-17) 3 days after blastocyst transfer, which was followed by a switch to anti-inflammatory cytokine profile (increase IL-10 and TGF-β1) by 6 days after blastocyst transfer and the latter increase was sustained 9 days after blastocyst transfer, when pregnancy was confirmed.

Abstract
PROBLEM It is unknown whether maternal cytokine production differs between twin and singleton gestations in the implantation phase. A difference in maternal serum cytokine concentrations in twins would imply a dose-response to the invading embryos, as opposed to a general immune reaction. METHOD OF STUDY A prospective longitudinal cohort of women aged 18-45 at an academic fertility center undergoing in vitro fertilization and embryo transfer (IVF-ET) underwent routine collection of serial serum samples starting 9 days after ET and then approximately every 48 hours thereafter. Cryopreserved aliquots of these samples were assayed for interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α), and C-X-C motif chemokine ligand 10 (CXCL10) using the SimplePlex immunoassay platform. Pregnancies were followed until delivery. Serial measures of serum concentrations of IL-10, CXCL10, and TNF-α in singleton or di-di twin pregnancies from 9 to 15 days after IVF-ET were compared. RESULTS Maternal serum levels of CXCL10 are significantly lower in women with di-di twin pregnancies in early implantation compared to those with singleton gestation (day 9-11, P = .02). Serum levels of TNF-α and IL-10 were comparable at all studied time points (P > .05). CONCLUSION Maternal serum levels of CXCL10 are significantly lower in the earliest implantation phase in di-di twins compared to singleton conceptions. Given the known anti-angiogenic role of CXCL10, we hypothesize that lower CXCL10 levels in twin implantations allow an environment that is conducive for the greater vascularization required for the establishment of dual placentation in di-di twins.

Abstract
BACKGROUND Endocannabinoids/endovanilloid (EC/EV) system and inflammation are recognized as key regulators of cell-signaling pathways in female reproduction. The knowledge of predictive biomarkers involved in preterm birth (PTB) represents an important goal to make an early diagnosis. The aim of the study was to investigate the role of EC/EV system and inflammation in human delivery, in placental samples from spontaneous deliveries. METHODS We examined the expression of genes encoding for the components of EC/EV system (CB1, CB2, TRPV1, MAGL, FAAH, DAGL, NAPE-PLD) and for inflammatory cytokines (IL-6, TNF-α) with qRT-PCR techniques, in human placental samples from preterm delivery (at 30 and at 34 weeks) compared to term delivery (40 weeks, control group). RESULTS We found a marked increase of CB1, anandamide, and inflammatory cytokines, mainly TNF-α, together with TRPV1 down-regulation in term delivery group, compared to preterm groups (P<0.05). CONCLUSIONS Our findings highlighted the emergent pivotal role of the EC/EV system and inflammation in spontaneous term delivery and provided the framework for future studies that investigate the CB1/TRPV1 crosstalk in preterm birth. Particularly, we found a link between the stimulation of CB1 receptors and the antagonism of TRPV1 channels, that could be used in PTB prevention, through selected molecules.

IL-10 to TNFα ratios throughout early first trimester can discriminate healthy pregnancies from pregnancy losses. Am J Reprod Immunol 2019; 83:e13195. [PMID: 31585488 DOI: 10.1111/aji.13195] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 09/04/2019] [Accepted: 09/06/2019] [Indexed: 12/30/2022] Open
Abstract
PROBLEM Embryo implantation and placentation require a careful immunological balance. Cytokines such as IL-10 and TNFα have been implicated as markers of dysregulation, but have only been studied at a single time point or after a pregnancy loss. Our objective was to determine normative patterns of serum levels of IL-10 and TNFα and their ratio throughout the first trimester in healthy pregnancies and to determine if this pattern differs from pregnancy loss. METHOD OF STUDY Two prospective longitudinal cohorts of gravidae including in vitro fertilization (IVF) and naturally conceived pregnancies with serial blood draws. Cytokines were assayed using Simple Plex. In the IVF cohort, we monitored from the implantation day up to 6 weeks of gestation; whereas in the naturally conceived cohort, sample collection began at 4 weeks and throughout the whole first trimester. RESULTS IL-10 concentrations in normal pregnancies were significantly higher than in pregnancies ending in a loss starting at 6-8 weeks of gestation, while TNFα concentrations were significantly lower in normal than in pregnancies ending in a loss starting at 3-5 of gestation weeks. The IL-10 to TNFα ratio in normal pregnancies was significantly higher from 4 to 9 weeks compared to pregnancies that were lost (t test, P < .05). Changes were observed before any symptoms of miscarriage were present. CONCLUSION We provide evidences of differences in early immunomodulation in healthy pregnancies vs those destined to end in first-trimester loss. The ratio of IL-10 to TNFα rises significantly higher in viable pregnancies as early as 4.5 weeks compared to pregnancies loss.

Abstract
OBJECTIVE Limited data exist on child abuse-related immune variation during pregnancy, despite implications for maternal and infant health and extensive data showing that abuse history and depression are related to increased inflammation in other populations. This study examined associations among child abuse, depression, circulating levels of inflammatory markers, and perinatal health in pregnant adolescents, a group at high risk for childhood abuse and poor birth outcomes. METHODS Pregnant teenagers (n = 133; 14-19 years; 89.5% Latina) reported on abuse and depression and had two blood draws (24-27 and 34-37 gestational weeks, second and third trimesters, respectively) for interleukin-6 (IL-6) and C-reactive protein; birth outcomes were collected. RESULTS Abuse and depression interacted to predict higher IL-6 at second trimester (B = 0.006, p = .011) such that severely abused adolescents with high depression had higher IL-6 relative to severely abused adolescents with low depression; depression did not differentiate IL-6 levels for those with low abuse severity. Abuse and IL-6 also interacted to predict gestational age at birth (B = 0.004, p = .040) such that those with low abuse and high IL-6 and those with high abuse and low IL-6 had infants with earlier gestational age at birth. Cortisol at the second trimester mediated the association between IL-6 and gestational age at birth (indirect effect estimate=-0.143, p < .039). CONCLUSIONS Depression severity distinguished IL-6 levels among more severely abused pregnant Latina adolescents, but it was unrelated to IL-6 among less severely abused adolescents. Cortisol explained the relationship between IL-6 and earlier gestational age at birth. Multiple adversities and inflammation may influence birth outcomes and potentially affect intergenerational health.

Abstract
The aetiology of spontaneous miscarriage, the most common pregnancy complication, remains undefined. One of postulated factors involved in miscarriage pathology is interleukin 6 (IL-6). Therefore, the aim of the study was to evaluate IL-6 and interleukin 6 receptor (IL-6R) gene polymorphisms in patients with spontaneous miscarriage. One hundred fifty-seven patients diagnosed with spontaneous miscarriage and age and gestational time matched controls were included in the case-control study. In all study participants circulating IL-6 levels (chemiluminescent immunoassay) and IL6-174G>C as well as IL6R rs2228145:A>C polymorphisms were evaluated. The distribution of IL6 as well as IL6R alleles and genotypes were similar in the controls and patients with miscarriage. Only a trend of more frequent appearance of -174GC+CC and C allele in the patients with miscarriage was noted. Blood serum concentrations of IL-6 were significantly elevated in patients with miscarriage vs those with physiological pregnancy. Likewise, IL-6 concentrations differ significantly with the types of miscarriage. The highest concentrations of the cytokine was seen in subjects with incomplete miscarriage (4.28 ± 4.88 pg/ml) followed by imminent miscarriage (2.97 ± 2.42 pg/ml), and then missed miscarriage (2.07 ± 1.90 pg/ml), being significantly the lowest in missed miscarriage group. No association between the IL6 genotype and IL-6 serum concentration were noted, both in the miscarriage group and in the control group. The findings of the study support the role of IL-6 in spontaneous miscarriage irrespectively of its type. However, no correlation between circulating IL-6 and IL6 gene polymorphism, as well as IL-6 and IL-6R polymorphisms associations with spontaneous miscarriage were revealed.

Cyclosporine A enhances Th2 bias at the maternal-fetal interface in early human pregnancy with aid of the interaction between maternal and fetal cells. PLoS One 2012; 7:e45275.

Abstract
Our previous study has demonstrated that cyclosporine A (CsA) administration in vivo induces Th2 bias at the maternal-fetal interface, leading to improved murine pregnancy outcomes. Here, we investigated how CsA treatment in vitro induced Th2 bias at the human maternal-fetal interface in early pregnancy. The cell co-culture in vitro in different combination of component cells at the maternal-fetal interface was established to investigate the regulation of CsA on cytokine production from the interaction of these cells. It was found that interferon (IFN)-γ was produced only by decidual immune cells (DICs), and not by trophoblasts or decidual stromal cells (DSCs); all these cells secreted interleukin (IL)-4, IL-10, and tumor necrosis factor (TNF)-α. Treatment with CsA completely blocked IFN-γ production in DICs and inhibited TNF-α production in all examined cells. CsA increased IL-10 and IL-4 production in trophoblasts co-cultured with DSCs and DICs although CsA treatment did not affect IL-10 or IL-4 production in any of the cells when cultured alone. These results suggest that CsA promotes Th2 bias at the maternal-fetal interface by increasing Th2-type cytokine production in trophoblasts with the aid of DSCs and DICs, while inhibiting Th1-type cytokine production in DICs and TNF-α production in all investigated cells. Our study might be useful in clinical therapeutics for spontaneous pregnancy wastage and other pregnancy complications.

Pro-inflammatory cytokine-stimulated first trimester decidual cells enhance macrophage-induced apoptosis of extravillous trophoblasts. Placenta 2011; 33:188-94. [PMID: 22212249 DOI: 10.1016/j.placenta.2011.12.007] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2011] [Revised: 12/08/2011] [Accepted: 12/09/2011] [Indexed: 01/13/2023]
Abstract
OBJECTIVE As human blastocyst-derived extravillous trophoblasts (EVTs) invade the early decidua, they are positioned to interact with immune cells and resident decidual cells, and remodel spiral arteries into high capacity vessels that increase blood flow to the developing fetal-placental unit. Shallow EVT invasion elicits incomplete vascular transformation and reduces uteroplacental blood flow that presages adverse pregnancy outcomes. Excess macrophages in the decidua induce EVT apoptosis via tumor necrosis factor-alpha (TNF-α) secretion. Our previous observation that pro-inflammatory cytokines enhance neutrophil and macrophage activator granulocyte-macrophage colony-stimulating factor (GM-CSF) expression in first trimester decidual cells is now extended to include: (1) the specific macrophage activator M-CSF; (2) macrophage activation and subsequent enhancement of EVT apoptosis by both GM-CSF and M-CSF. STUDY DESIGN Quantitative reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay assessed M-CSF expression in first trimester decidual cells incubated with interleukin-1 beta (IL-1β) or TNF-α. Peripheral monocyte-derived macrophages pre-incubated with conditioned media from decidual cell cultures were co-cultured with a first trimester EVT cell line, HTR-8/SVneo cells. Macrophage activation was examined and EVT apoptosis evaluated by DNA fragmentation, caspase activation and cell membrane asymmetry. RESULTS IL-1β or TNF-α significantly enhanced M-CSF expression in first trimester decidual cells. The conditioned media from these cultures activates macrophages, which promote caspase 3/7-dependent EVT apoptosis with antibodies against GM-CSF or M-CSF blocking this effect. CONCLUSIONS Pro-inflammatory cytokines increases synthesis of M-CSF in first trimester decidual cells. Both GM-CSF and M-CSF activate macrophages, which initiate caspase-dependent EVT apoptosis.

Abstract
BACKGROUND Vitamin D has been implicated in embryo/placental development and growth; however information in this regard is limited or unavailable. OBJECTIVE To assess 25-hydroxyvitamin D (25(OH)D), free β-human chorionic gonadotropin (β-hCG) and pregnancy associated plasma protein A (PAPP-A) status during pregnancy. METHODS Serum 25(OH)D, β-hCG, and PAPP-A levels were measured in the first trimester of otherwise healthy Spanish pregnant women (n=488). Rho Spearman coefficients were calculated to determine correlations between analytes. RESULTS Median serum 25(OH)D levels for the entire sample was 27.4 ng/ml (interquartile range=12.1). 25(OH)D levels were insufficient (20-29.99 ng/ml) and deficient (<20 ng/ml) in 40.6% and 23.2%, respectively, in relation to ethnics, body mass index values, tobacco use, and season/gestational age at blood sampling. β-hCG and PAPP-A levels significantly correlated (r²=0.47) yet neither of them with 25(OH)D levels. Despite this, the three analytes significantly correlated with gestational age at sampling. CONCLUSION First trimester 25(OH)D, β-hCG, and PAPP-A levels increase with gestational age; however, placental peptides do not correlate with vitamin D levels, suggesting a non-placental 25(OH)D production. More research is required in this regard.
