Maternal and fetal outcomes in women with cerebrovascular malformations in pregnancy: A multicentre retrospective cohort study.

OBJECTIVE: To determine maternal, obstetric and neonatal outcomes in a cohort of women with cerebrovascular malformations (CVMs) that include arterial venous malformations (AVMs) and cavernomas. DESIGN: Retrospective cohort study. SETTING: Six specialist centres managing pregnant women with neurological disorders. POPULATION: Sixty-three women with CVMs in 83 pregnancies of ≥20 completed weeks' gestation. METHODS: Retrospective case notes review. MAIN OUTCOME MEASURES: Neurological outcomes including rates of acute cerebral bleeding in pregnancy and reported seizures during pregnancy. Maternal outcomes included number of women with a livebirth and the proportion of women being delivered by caesarean section. RESULTS: Most women had a good pregnancy outcome with high rates of vaginal delivery (73%) at term. There were no maternal deaths. Six women had an acute cerebral bleed, all of whom were delivered by planned caesarean section. In total, ten women had seizures in pregnancy (of whom four also had a bleed). Six (7%) babies were admitted to a neonatal unit. There was no significant difference in outcomes between women with AVMs and those with cavernomas. CONCLUSION: In the majority of cases, pregnancy outcomes were favourable, with most women having a vaginal delivery. All cases of cerebral bleeds that occurred were at a remove from the peripartum period. TWEETABLE ABSTRACT: Women with cerebrovascular malformations have high rates of vaginal delivery.

Use of interleukin-6 receptor antibodies in the second and third trimester of pregnancy: a retrospective cohort study.

BACKGROUND: A paucity of data exists to inform the use of interleukin (IL)-6 receptor antibodies (anti-IL-6) in pregnancy, particularly in the third trimester. This study aimed to describe outcomes of pregnant women and their neonates exposed to these medications given after the first trimester to treat COVID-19. METHODS: In this retrospective cohort study, we included all women with COVID-19 who were treated with an anti-IL-6 during pregnancy at two tertiary hospitals in London, UK-Guy's and St Thomas' NHS Foundation Trust and Imperial College Healthcare NHS Trust-between March 1, 2020, and Sept 30, 2022. Maternal demographics, clinical data, administered medications, and maternal and neonatal outcomes were assessed for all included women via a review of medical records and through maternal medicine networks. FINDINGS: 25 women received an anti-IL-6 for COVID-19 in pregnancy during the study period and were followed up for 12 months. The group described were a population at high risk, with 24 requiring level two or three critical care. 24 women received tocilizumab and one received sarilumab. All women were prescribed at least three concomitant medications. 16 received the anti-IL-6 in the third trimester of pregnancy and nine during the seocnd trimester. There were no women with maternal neutropenia or pancytopenia; increases in liver enzymes in 16 of 20 women with available alanine aminotransferase data were in keeping with the severity of COVID-19 reported and all three women who developed a secondary bacterial infection mounted a C-reactive protein response. There was one maternal death due to COVID-19. All pregnancies resulted in livebirths and there was one twin pregnancy. 16 of 26 babies were born preterm. One baby died at age 6 months due to complications of extreme prematurity. A transient neonatal cytopenia was described in six of 19 babies in whom a full blood count was performed. Although these findings are likely to be in keeping with prematurity alone, we cannot exclude the possibility that transplacental transfer of anti-IL-6 was contributory. INTERPRETATION: We report further data on the use of anti-IL-6 in the second and third trimesters of pregnancy for the management of COVID-19. When extrapolated, our data can inform shared decision making for individuals who would benefit from the use of anti-IL-6 into the third trimester of pregnancy for management of rheumatological disease. FUNDING: None.

A national cohort study and confidential enquiry to investigate ethnic disparities in maternal mortality.

BACKGROUND: Ethnic disparities in maternal mortality were first documented in the UK in the early 2000s but are known to be widening. This project aimed to describe the women who died in the UK during or up to a year after the end of pregnancy, to compare the quality of care received by women from different aggregated ethnic groups, and to identify any structural or cultural biases or discrimination affecting their care. METHODS: National surveillance data was used to identify all 1894 women who died during or up to a year after the end of pregnancy between 2009 and 18 in the UK. Their characteristics and causes of death were described. A Confidential Enquiry was undertaken to describe the quality of care women received. The care of a stratified random sample of 54 women who died during or up to a year after the end of pregnancy between 2009 and 18, (18 from the aggregated group of Black women, 19 from the Asian aggregated group and 17 from the White aggregated group) was re-examined specifically to describe any structural or cultural biases or discrimination identified. FINDINGS: There were no major differences causes of death between women from different aggregated ethnic groups, with cardiovascular disease the leading cause of death in all groups. Multiple areas of bias were identified in the care women received, including lack of nuanced care (notable amongst women from Black aggregated ethnic groups who died), microaggressions (most prominent in the care of women from Asian aggregated ethnic groups who died) and clinical, social and cultural complexity (evident across all ethnic groups). INTERPRETATION: This confidential enquiry suggests that multiple structural and other biases exist in UK maternity care. Further research on the role of microaggressions is warranted.

Macroprolactinomas and Nonfunctioning Pituitary Adenomas and Pregnancy Outcomes.

OBJECTIVE: To examine the monitoring, management, and outcomes of pituitary tumors in pregnancy. METHODS: A national, prospective, observational, population-based case series study was conducted in all U.K. consultant-led obstetric units over 3 years using the U.K. Obstetric Surveillance System. To evaluate rates of adverse pregnancy outcomes, women with a macroprolactinoma (10 mm or greater) or nonfunctioning pituitary adenoma, diagnosed before or during pregnancy, were compared with two comparison groups: 1) a U.K. Obstetric Surveillance System cohort with singleton (n=2,205) or twin (n=27) pregnancy; and 2) data from the Office of National Statistics (n=2,703,102). Main outcome measures were the incidence, management, and frequency of adverse maternal and offspring outcomes of pituitary tumors in pregnancy. RESULTS: There were 71 confirmed cases of pituitary tumors in pregnancy (49 macrolactinoma, 16 nonfunctioning adenomas, three acromegaly, three Cushing's disease). The women with pituitary tumors were 4 years older than comparison women (P<.001). None of the nine women treated with surgery or radiotherapy before pregnancy had symptomatic tumor expansion. This occurred in 6 of 40 women with macroprolactinomas and one of seven nonfunctioning adenomas diagnosed before conception and in three of five women with nonfunctioning adenomas diagnosed in pregnancy. Two women had pituitary apoplexy, both of whom also had symptoms of expansion of tumor or surrounding pituitary tissue. To within the level of accuracy possible, there was no evidence that pituitary tumors were associated with adverse pregnancy outcomes (pregnancy-induced hypertension, preeclampsia, preterm labor, stillbirth). Women with nonfunctioning adenomas were more likely to have cesarean delivery compared with women in a control group (relative risk 2.06, confidence interval 1.26-3.36, P=.035). CONCLUSION: The majority of women with macroprolactinomas and nonfunctioning adenomas have good pregnancy outcomes. Nonfunctioning pituitary adenomas occur more commonly in pregnancy than previously thought and can present de novo with symptoms of pituitary expansion in pregnancy.

Cytomegalovirus may mimic the presentation of intrahepatic cholestasis and hemolysis, elevated liver enzymes and low platelets in immunosuppressed pregnant women.

Most published cases of cytomegalovirus infection in pregnancy relate to congenital abnormalities in neonates infected in early pregnancy, while the mother remains asymptomatic. We describe a diagnostically challenging case of an immunosuppressed woman with scleroderma who developed deranged liver function tests attributed to intrahepatic cholestasis of pregnancy and haemolysis, elevated liver enzymes and low platelets syndrome but was ultimately found to have disseminated cytomegalovirus. Cytomegalovirus can present in a myriad of ways. Clinicians caring for immunocompromised pregnant women should consider cytomegalovirus as a possible differential diagnosis when reviewing abnormal liver function tests.

Contraception in women with medical problems.

Women with medical disease have a higher incidence of maternal mortality compared with healthy women, with cardiac disease now being the most common cause of maternal death in the UK. A handful of medical conditions exist where pregnancy is not recommended due to mortality rates approaching 50%. It is imperative that such women have the most reliable methods of contraception available. Contraceptive agents may themselves affect medical disease, or may interact with medications used by such women. There may be a range of contraceptive agents suitable for each medical condition. The contraceptive selected should be tailored to suit the individual. The following points should be considered when deciding on the most appropriate contraceptive agent: efficacy, thrombotic risk (oestrogen containing contraceptives), arterial risks (oestrogen containing contraceptives), infective risk (e.g. insertion of intrauterine device [IUD]), vagal stimulation (e.g. insertion of IUD, ESSURE(®)), bleeding risks with patients on anticoagulants, interaction with concomitant drugs, effects of anaesthesia and ease of use. This review aims to cover the different contraceptive agents available and the best ones to use for certain medical illnesses.
