Abstract STUDY QUESTION Does the cause of infertility affect the perinatal outcomes preterm birth (PTB) and low birth weight (LBW) following IVF treatment? SUMMARY ANSWER The risk of PTB and LBW was higher with female causes of infertility—ovulatory disorders, tubal disorders and endometriosis—compared to unexplained infertility but the absolute increase in risk was low. WHAT IS KNOWN ALREADY Infertility is associated with an increased risk of adverse perinatal outcomes. Risk of adverse perinatal outcomes is also higher following ART compared to spontaneous conceptions. Infertility can result from female and/or male factors or is unexplained when the cause cannot be delineated by standard investigations. Given that infertility and ART are contributory to the adverse perinatal outcomes, it is a matter of interest to delineate if the specific cause of infertility influences perinatal outcomes following IVF treatment. STUDY DESIGN, SIZE, DURATION Anonymous data were obtained from the Human Fertilization and Embryology Authority (HFEA). The HFEA has collected data prospectively on all ART cycles performed in the UK since 1991. Data from 1991 to 2016 comprising a total of 117 401 singleton live births following IVF with or without ICSI (IVF ± ICSI) for sole causes of infertility were analysed for PTB and LBW. Cycles having more than one cause of infertility and/or multiple births were excluded. PARTICIPANTS/MATERIALS, SETTING, METHODS Data on all women undergoing stimulated IVF ± ICSI treatment cycles were analysed to compare perinatal outcomes of PTB and LBW among singleton live births based on the cause of infertility (ovulatory disorders, tubal disorders, endometriosis, male factor, unexplained). Logistic regression analysis was performed, adjusting for female age category, period of treatment, previous live births, IVF or ICSI, number of embryos transferred and fresh or frozen embryo transfer cycles. MAIN RESULTS AND THE ROLE OF CHANCE Compared to unexplained infertility, the risk of PTB was significantly higher with ovulatory disorders (adjusted odds ratio (aOR) 1.31, 99.5% CI 1.17 to 1.46); tubal disorders (aOR 1.25, 99.5% CI 1.14 to 1.38) and endometriosis (aOR 1.17, 99.5% CI 1.01 to 1.35). There was no significant difference in the risk of PTB with male factor causes compared to unexplained infertility (aOR 1.01, 99.5% CI 0.93, 1.10). The risk of LBW was significantly higher with ovulatory disorders (aOR 1. 29, 99.5% CI 1.16 to 1.44) and tubal disorders (aOR 1.12, 99.5% CI 1.02 to 1.23) and there was no increase in the risk of LBW with endometriosis (aOR 1.11, 99.5% CI 0.96 to 1.30) and male factor causes (aOR 0.94, 99.5% CI 0.87, 1.03), compared to unexplained infertility. LIMITATIONS, REASONS FOR CAUTION Although the analysis was adjusted for several important confounders, there was no information on the medical history of women during pregnancy to allow adjustment. The limitations with observational data would apply to this study, including residual confounding. WIDER IMPLICATIONS OF THE FINDINGS This is the largest study to address the causes of infertility affecting perinatal outcomes of PTB and LBW. The information is important for the management of pregnancies and the underlying reasons for the associations observed need to be further understood.

Pregnancy Risk

Background: Pregnancy may increase the risk of Human Papillomavirus (HPV) infection because of pregnancy induced immune suppression. The objective of this study was to use a large population-based dataset to estimate the prevalence of HPV infection and its association with adverse outcomes among pregnant women. Methods: We analyzed Pregnancy Risk Monitoring System data from 2004-2011 (N=26,085) to estimate the self-reported HPV infection. Survey logistic procedures were used to examine the relationship between HPV infection and adverse perinatal outcomes. Results: Approximately 1.4% of women were estimated to have HPV infection during their pregnancy. The prevalence of adverse outcomes in this sample was preterm birth (8.4%), preeclampsia (7.5%), low birth weight (6.3%) and premature rupture of membranes (2.8%). Compared to women without HPV infection, HPV infection positive women were much more likely to have had other infections such as chlamydia (9.23% vs. 2.12%, p-value <.0001), Group B Strep (21.7% vs. 10.04%, p-value <.0001), and herpes (7.17% vs. 1.07%, p-value <.0001). After adjusting for other risk factors including other infections, HPV infection was significantly associated with low birth weight (OR: 1.94, 95% CI: 1.14-3.30). Conclusion: The study indicated a potential association between HPV infection and low birth weight. Because pregnant women with HPV infection are at higher risk of other infections, future research may focus on the roles of co-infection in the development of adverse perinatal effects.

Adverse Perinatal Outcomes

Abstract Background Racial disparities in adverse perinatal outcomes have been studied in other countries, but little has been done for the Canadian population. In this study, we sought to examine the disparities in adverse perinatal outcomes between Asians and Caucasians in Ontario, Canada. Methods We conducted a population-based retrospective cohort study that included all Asian and Caucasian women who attended a prenatal screening and resulted in a singleton birth in an Ontario hospital (April 1st, 2015-March 31st, 2017). Generalized estimating equation models were used to estimate the independent adjusted relative risks and adjusted risk difference of adverse perinatal outcomes for Asians compared with Caucasians. Results Among 237,293 eligible women, 31% were Asian and 69% were Caucasian. Asians were at an increased risk of gestational diabetes mellitus, placental previa, early preterm birth (< 32 weeks), preterm birth, emergency cesarean section, 3rd and 4th degree perineal tears, low birth weight (< 2500 g, < 1500 g), small-for-gestational-age (<10th percentile, <3rd percentile), neonatal intensive care unit admission, and hyperbilirubinemia requiring treatment, but had lower risks of preeclampsia, macrosomia (birth weight > 4000 g), large-for-gestational-age neonates, 5-min Apgar score < 7, and arterial cord pH ≤7.1, as compared with Caucasians. No difference in risk of elective cesarean section was observed between Asians and Caucasians. Conclusion There are significant differences in several adverse perinatal outcomes between Asians and Caucasians. These differences should be taken into consideration for clinical practices due to the large Asian population in Canada.

Background: Cardiac disease is one of the non obstetric problems causing mortality both in pregnancy and labor due to the complications. Preventions for the complications have not been implemented, thus the number of patients which have cardiac disease with complications and perinatal outcome with low birth weight is still high. Objective : To identify maternal and neonatal outcome of pregnant women with cardiac disease in dr. Soetomo Surabaya hospital in 2018. Method: Descriptive retrospective study using medical records in dr. Soetomo Surabaya hospital 2018. Result: We found 1433 pregnancy cases with 51 (3,6 %) patients were having cardiac disease and included in this research. The most common maternal complication was pulmonary hypertension 16 cases. A dead case was found 1 case (1,9 %) with eissenmenger syndrome. We found the perinatal outcome of 30 babies (58.8%) born with a weight of 2500 gram and under. There are 7 patients with cardiac disease that have been corrected (13,7%). Among those 7 patients, 6 had a perinatal outcome with a birth weight of more than 2500 gram. Conclusion : Most pregnant patients with cardiac disease in dr. Soetomo Surabaya hospital 2018 are already having some complications with perinatal outcomes of low birth weight. Therefore, management of cardiac disease in pregnancy to prevent complications by means of preconception counseling, good antenatal care, and appropriate referrels are still needed to improve the quality of maternal and neonatal outcomes.

Abstract STUDY QUESTION Is the use of donor oocytes in women <35 years of age associated with an increased risk of adverse perinatal outcomes compared to use of autologous oocytes? SUMMARY ANSWER Among fresh assisted reproductive technology (ART) cycles performed in women under age 35, donor oocyte use is associated with a higher risk of preterm birth, low birth weight and stillbirth (when zero embryos were cryopreserved) as compared to autologous oocytes. WHAT IS KNOWN ALREADY Previous studies demonstrated elevated risk of poor perinatal outcomes with donor versus autologous oocytes during ART, primarily among older women. STUDY DESIGN, SIZE, DURATION Retrospective cohort study using data reported to Centers for Disease Control and Prevention’s National ART Surveillance System (NASS) during the period from 2010 to 2015 in order to best reflect advances in clinical practice. Approximately 98% of all US ART cycles are reported to NASS, and discrepancy rates were <6% for all fields evaluated in 2015. PARTICIPANTS/MATERIALS, SETTING, METHODS We included all non-banking fresh and frozen ART cycles performed between 2010 and 2015 in women under age 35 using autologous or donor eggs. Cycles using cryopreserved eggs, donated embryos or a gestational carrier were excluded. Among fresh embryo transfer cycles, we calculated predicted marginal proportions to estimate the unadjusted and adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) for the association between donor versus autologous oocyte use and stillbirth, spontaneous abortion, preterm delivery and low birth weight among singleton pregnancies or births. Stillbirth models were stratified by number of embryos cryopreserved. All models were adjusted for patient and treatment characteristics. MAIN RESULTS AND THE ROLE OF CHANCE Among the 71 720 singleton pregnancies occurring during 2010–2015, singletons resulting from donor oocytes were more likely to be preterm (15.6% versus 11.0%; aRRs 1.39: CI 1.20–1.61) and have low birth weight (11.8% versus 8.8%; aRRs 1.34; CI 1.16–1.55) than those resulting from autologous oocytes. With zero embryos cryopreserved, donor versus autologous oocyte use was associated with increased risk for stillbirth (2.1% versus 0.6%; aRRs 3.73; CI 1.96–7.11); no association with stillbirth was found when ≥1 embryo was cryopreserved (0.54% versus 0.56%; aRR 1.15; CI 0.59–2.25). LIMITATIONS, REASONS FOR CAUTION The data come from a national surveillance system and is thus limited by the accuracy of the data entered by individual providers and clinics. There may be unmeasured differences between women using donor eggs versus their own eggs that could be contributing to the reported associations. Given the large sample size, statistically significant findings may not reflect clinically important variations. WIDER IMPLICATIONS OF THE FINDINGS Risks of preterm birth, low birth weight and stillbirth among singleton pregnancies using donor oocytes were increased compared to those using autologous oocytes. Further study regarding the pathophysiology of the potentially increased risks among donor oocyte recipient pregnancy is warranted. STUDY FUNDING/COMPETING INTEREST(S) None.
