A Review of Systemic Corticosteroid Use in Pregnancy and the Risk of Select Pregnancy and Birth Outcomes

Pyoderma Gangrenosum, a Challenging Postpartum Diagnosis-Case Report and Literature Review

Background/Objectives: The infrequent occurrence of pyoderma gangrenosum (PG) during pregnancy and in postpartum, with its subsequent diagnostic intricacies, caused us to present the following case. Methods: This article describes a rare case of PG in postpartum in a patient without any prior pathology and a short review of the literature, aiming to identify similar rare instances. Results: We conducted a literature review to ascertain the prevalence of postpartum pyoderma gangrenosum, and we identified a total of 41 cases. Conclusions: Our article underlines again the importance of interdisciplinary collaboration for the prompt identification and commencement of necessary therapeutic interventions in postpartum women afflicted by pyoderma gangrenosum.

Pregnancy after transplant in the older adolescent: Anticipatory guidance for the pediatric provider

BACKGROUND

Healthcare providers who care for adolescent and young adult transplant recipients should be aware of contraception counseling and potential for pregnancy in this at-risk cohort.

METHODS

This paper will review contraceptive options in general for transplant recipients. There will also be a review of common immunosuppressive medications and their risk profile regarding pregnancy after transplantation. Data from the Transplant Pregnancy Registry International were analyzed looking at recipients conceiving under the age of 21 and were compared to overall pregnancy outcomes.

RESULTS

Overall pregnancy outcomes in recipients under the age of 21 are like the adult cohort.

CONCLUSION

It is imperative to provide contraception counseling to the adolescent and young adult and inform their caregiver that pregnancy can happen if the recipient is sexually active. Pregnant adolescent and young adult transplant recipients should be followed by a multidisciplinary team to assure a positive outcome for the recipient, transplant, and neonate.

Clinical Characteristics, Outcomes, and Risk Factors for Mortality in Pregnant/Puerperal Women with COVID-19 Admitted to ICU in Turkey: A Multicenter, Retrospective Study from a Middle-Income Country

BACKGROUND

Coronaviruses have been the cause of 3 major outbreaks during the last 2 decades. Information on coronavirus diseases in pregnant women is limited, and even less is known about seriously ill pregnant women. Data are also lacking regarding the real burden of coronavirus disease 2019 (COVID-19) infection in pregnant women from low/middle-income countries. The aim of this study was to determine the characteristics and clinical course of COVID-19 in pregnant/puerperal women admitted to ICUs in Turkey.

METHODS

This was a national, multicenter, retrospective study. The study population comprised all SARS-CoV-2-infected pregnant/puerperal women admitted to participating ICUs between 1 March 2020 and 1 January 2022. Data regarding demographics, comorbidities, illness severity, therapies, extrapulmonary organ injuries, non-COVID-19 infections, and maternal and fetal/neonatal outcomes were recorded. LASSO logistic regression and multiple logistic regression analyses were used to identify predictive variables in terms of ICU mortality.

RESULTS

A total of 597 patients (341 pregnant women, 255 puerperal women) from 59 ICUs in 44 hospitals were included and of these patients, 87.1% were unvaccinated. The primary reason for ICU admission was acute hypoxemic respiratory failure in 522 (87.4%), acute hypoxemic respiratory failure plus shock in 14 (2.3%), ischemic cerebrovascular accident (CVA) in 5 (0.8%), preeclampsia/eclampsia/HELLP syndrome in 6 (1.0%), and post-caesarean follow-up in 36 (6.0%). Nonsurvivors were sicker than survivors upon ICU admission, with higher APACHE II (p < 0.001) and SOFA scores (p < 0.001). A total of 181 (30.3%) women died and 280 (46.6%) had received invasive mechanical ventilation (IMV). Myocardial injury, the highest SOFA score during ICU stay, LDH levels on admission, the highest levels of AST during ICU stay, average daily dose of corticosteroids, IMV, prophylactic dose anticoagulation (compared with therapeutic dose anticoagulation), PaO2/FiO2 ratio <100, pulmonary embolism, and shock were identified as predictors of mortality. Rates of premature birth (46.4%), cesarean section (53.7%), fetal distress (15.3%), stillbirth (6.5%), and low birth weight (19.4%) were high. Rates of neonatal death (8%) and respiratory distress syndrome (21%) were also high among live-born infants.

CONCLUSIONS

Severe/critical COVID-19 infection during the pregnancy/puerperal period was associated with high maternal mortality and fetal/neonatal complication rates in Turkey.

Environmental Exposures and Risks During Pregnancy

The Women in Wilderness Medicine Research Committee of the Wilderness Medical Society conducted a narrative review to address considerations for pregnant individuals in wilderness environments. There is limited evidence behind many opinion-based recommendations on the safety of various environmental exposures in pregnancy. The authors reviewed the literature for the best available evidence, including observational studies, case series, limited controlled trials, and extrapolation from physiological data, as well as evaluating expert consensus statements. The benefits of exposure to natural environments include better pregnancy outcomes and improved maternal mental and physical health. Risks are similar to nonpregnant individuals with the added risks associated with maternal-fetal physiology in wilderness environments and difficulties of evacuation. This narrative review discusses pregnancy-specific concerns in extreme environments, including high altitude, hypothermia, hyperthermia, lightning strikes, envenomations, and common outdoor exposures.

Task force of the Brazilian Society of Otology - evaluation and management of peripheral facial palsy

OBJECTIVE

To review key evidence-based recommendations for the diagnosis and treatment of peripheral facial palsy in children and adults.

METHODS

Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on peripheral facial palsy were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions.

RESULTS

The topics were divided into 2 main parts: (1) Evaluation and diagnosis of facial palsy: electrophysiologic tests, idiopathic facial palsy, Ramsay Hunt syndrome, traumatic peripheral facial palsy, recurrent peripheral facial palsy, facial nerve tumors, and peripheral facial palsy in children; and (2) Rehabilitation procedures: surgical decompression of the facial nerve, facial nerve grafting, surgical treatment of long-term peripheral facial palsy, and non-surgical rehabilitation of the facial nerve.

CONCLUSIONS

Peripheral facial palsy is a condition of diverse etiology. Treatment should be individualized according to the cause of facial nerve dysfunction, but the literature presents better evidence-based recommendations for systemic corticosteroid therapy.

Parvovirus B19 in Pregnancy

Importance

Although the risk of parvovirus B19 infection during pregnancy and subsequent risk of adverse fetal outcome are low, understanding management practices is essential for proper treatment of fetuses with nonimmune hydrops fetalis. In addition, continued investigation into delivery management, breastfeeding recommendations, and congenital abnormalities associated with pregnancies complicated by parvovirus B19 infection is needed.

Objective

This review describes the risks associated with parvovirus B19 infection during pregnancy and the management strategies for fetuses with vertically transmitted infections.

Evidence Acquisition

Original articles were obtained from literature search in PubMed, Medline, and OVID; pertinent articles were reviewed.

Results

Parvovirus B19 is a viral infection associated with negative pregnancy outcomes. Up to 50% of people of reproductive age are susceptible to the virus. The incidence of B19 in pregnancy is between 0.61% and 1.24%, and, overall, there is 30% risk of vertical transmission when infection is acquired during pregnancy. Although most pregnancies progress without negative outcomes, viral infection of the fetus may result in severe anemia, congestive heart failure, and hydrops fetalis. In addition, vertical transmission carries a 5% to 10% chance of fetal loss. In pregnancies affected by fetal B19 infection, Doppler examination of the middle cerebral artery peak systolic velocity should be initiated to surveil for fetal anemia. In the case of severe fetal anemia, standard fetal therapy involves an intrauterine transfusion of red blood cells with the goal of raising hematocrit levels to approximately 40% to 50% of total blood volume. One transfusion is usually sufficient, although continued surveillance may indicate the need for subsequent transfusions. There are fewer epidemiologic data concerning neonatal risks of congenital parvovirus, although case reports have shown that fetuses with severe anemia in utero may have persistent anemia, thrombocytopenia, and edema in the neonatal period.

Conclusions and Relevance

Parvovirus B19 is a common virus; seropositivity in the geriatric population reportedly reaches 85%. Within the pregnant population, up to 50% of patients have not previously been exposed to the virus and consequently lack protective immunity. Concern for parvovirus B19 infection in pregnancy largely surrounds the consequences of vertical transmission of the virus to the fetus. Should vertical transmission occur, the overall risk of fetal loss is between 5% and 10%. Thus, understanding the incidence, risks, and management strategies of pregnancies complicated by parvovirus B19 is essential to optimizing care and outcomes. Further, there is currently a gap in evidence regarding delivery management, breastfeeding recommendations, and the risks of congenital abnormalities in pregnancies complicated by parvovirus B19. Additional investigations into optimal delivery management, feeding plans, and recommended neonatal surveillance are needed in this cohort of patients.

Asthma in pregnancy: a review of recent literature

PURPOSE OF REVIEW

Asthma remains the most common respiratory disease in pregnancy. Identifying risk factors for asthma exacerbations during pregnancy is critical, as uncontrolled asthma can have detrimental effects for both mother and baby. In this review, we discuss recent literature exploring risk factors, fetal and maternal effects, and treatment options for asthma during pregnancy.

RECENT FINDINGS

Recent literature suggests that optimizing asthma during pregnancy improves outcomes for both mother and baby, as well as later in childhood. Current research affirms that the benefit of asthma medication use outweighs any potential risks related to the medications themselves. Limited information is available regarding the use of newer therapies such as biologics during pregnancy.

SUMMARY

Identifying risk factors for asthma exacerbations during pregnancy is critical to prevent adverse outcomes for both mother and baby. Recent evidence continues to affirm the safety of asthma medication use; more studies are needed regarding the use of new therapies during pregnancy.

COVID-19 and pregnancy: A European study on pre- and post-infection medication use

PURPOSE

The COVID-19 pandemic has impacted medication needs and prescribing practices, including those affecting pregnant women. Our goal was to investigate patterns of medication use among pregnant women with COVID-19, focusing on variations by trimester of infection and location.

METHODS

We conducted an observational study using six electronic healthcare databases from six European regions (Aragon/Spain; France; Norway; Tuscany, Italy; Valencia/Spain; and Wales/UK). The prevalence of primary care prescribing or dispensing was compared in the 30-day periods before and after a positive COVID-19 test or diagnosis.

RESULTS

The study included 294,126 pregnant women, of whom 8943 (3.0%) tested positive for, or were diagnosed with, COVID-19 during their pregnancy. A significantly higher use of antithrombotic medications was observed particularly after COVID-19 infection in the second and third trimesters. The highest increase was observed in the Valencia region where use of antithrombotic medications in the third trimester increased from 3.8% before COVID-19 to 61.9% after the infection. Increases in other countries were lower; for example, in Norway, the prevalence of antithrombotic medication use changed from around 1-2% before to around 6% after COVID-19 in the third trimester. Smaller and less consistent increases were observed in the use of other drug classes, such as antimicrobials and systemic corticosteroids.

CONCLUSION

Our findings highlight the substantial impact of COVID-19 on primary care medication use among pregnant women, with a marked increase in the use of antithrombotic medications post-COVID-19. These results underscore the need for further research to understand the broader implications of these patterns on maternal and neonatal/fetal health outcomes.

Considerations in the management of ocular toxoplasmosis in pregnancy: a review of literature

Ocular toxoplasmosis is the most common cause of infectious posterior uveitis. Available literature is still conflicting regarding the incidence of recurrence during pregnancy as various calculations were employed in the different published studies. Although earlier reports have suggested a difference in presentation and an increase in severity during pregnancy, newer studies appear to show otherwise. Further diagnostic testing, including serologic and intraocular fluid sampling, may be indicated to increase the diagnostic accuracy in this special population of patients. The management of ocular toxoplasmosis during pregnancy is challenging as the foetus is additionally considered in the choice of treatment. Traditionally preferred anti-toxoplasmosis regimens containing antifolate drugs, such as pyrimethamine and trimethoprim-sulfamethoxazole, cannot be used routinely in pregnant patients, especially during the first trimester. This review includes literature on alternative treatments for ocular toxoplasmosis during pregnancy, including spiramycin and intravitreal treatment options.

[Pregnancy and breastfeeding in women with multiple sclerosis]

The diagnosis of multiple sclerosis (MS) in women of reproductive age is associated with many uncertainties regarding childbearing and lactation. Pregnancies of MS patients are not usually considered high-risk pregnancies per se. The likelihood of pregnancy complications or adverse pregnancy outcomes is not increased by the disease; however, a careful planning of pregnancy is important in order to choose the treatment option with the greatest benefit for the mother and the least possible risk for the baby. For highly active courses of the disease, anti-CD20 antibodies, cladribine, or continued administration of natalizumab show the best data. Patients with MS can be supported in their desire to breastfeed. If women have had a very active disease course, it is recommended that treatment should be started as soon as possible postpartum. Interferon-beta preparations, glatiramer acetate and ofatumumab are also approved for use during breastfeeding but off-label breastfeeding is also possible with other monoclonal antibodies.

Does anti-HPA-1a affect birthweight in fetal and neonatal alloimmune thrombocytopenia?

BACKGROUND

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) ensues from parental incompatibility for platelet alloantigens with maternal sensitization. HPA-1a/1b incompatibility is the most common cause of FNAIT in Caucasians. Placental villitis and lower birthweight in FNAIT suggest anti-HPA-1a may have effects beyond inducing thrombocytopenia.

OBJECTIVES

Does FNAIT secondary to anti-HPA-1a result in smaller newborns and, the corollary, does antenatal management of FNAIT increase birthweight?

STUDY DESIGN

Birthweights of 270 FNAIT-affected newborns from a randomized clinical trial and a NAITbabies.org survey (135 paired siblings) were compared with those of published controls and treated to untreated FNAIT-affected siblings. Birthweights were converted to percentiles to account for gestational age, sex, and role of birth order in birth weight. Body weights of FNAIT-affected and -unaffected pups in a mouse FNAIT model were analyzed.

RESULTS

Untreated siblings in both the clinical trial and NAITbabies.org cohorts were not small, compared with normal controls. However, treated siblings in both cohorts had significantly higher birthweight percentiles compared with their previous untreated affected sibling. After accounting for gestational age, sex, and birth order, increased birthweight percentile in treated compared with the untreated siblings remained significant in both cohorts. FNAIT-affected neonatal mice had lower bodyweights than FNAIT-unaffected pups.

CONCLUSIONS

Untreated FNAIT-affected newborns were not small; however, treatment of FNAIT-affected pregnancies increased newborn birthweights despite corrections to account for other factors that might have influenced the results. High dose IVIG is believed to "block" FcRn and lower maternal anti-HPA-1a levels, and thus increase birthweights by reducing levels of maternal anti-HPA-1a and reducing placental villitis.

Vogt-Koyanagi-Harada disease in pregnancy: Case report and review of 32 patients in the literature

Key Clinical Message

Systemic prednisolone including steroid pulse therapy would be safe in 32 pregnant women, who developed Vogt-Koyanagi-Harada disease in the literature. Prednisolone administration would be shortened by monitoring of serous retinal detachment with optical coherence tomography.

Abstract

A 30-year-old woman in 31 weeks of pregnancy with metamorphopsia and headache was diagnosed Vogt-Koyanagi-Harada disease. She underwent steroid pulse therapy and oral prednisolone 20 mg daily for 3 weeks until complete resolution of serous retinal detachment monitored by optical coherence tomography. Oral prednisolone was tapered and discontinued until uneventful delivery.

Gestational diabetes mellitus and late preterm birth: outcomes with and without antenatal corticosteroid exposure

BACKGROUND

Unlike pregestational diabetes mellitus, the American College of Obstetricians and Gynecologists recommends antenatal corticosteroids in those with gestational diabetes mellitus at risk for preterm birth. However, this recommendation is based on limited data, only 10.6% of the Antenatal Late Preterm Steroids study sample had gestational diabetes mellitus. There is a paucity of data on the risk of neonatal respiratory and other morbidity in this population.

OBJECTIVE

This study aimed to examine respiratory outcomes in parturients with gestational diabetes mellitus who received antenatal corticosteroids and delivered during the late preterm period vs those who did not.

STUDY DESIGN

This population-based cohort study used the US Vital Statistics dataset between 2016 to 2020. The inclusion criteria were singleton, nonanomalous individuals who delivered between 34.0 to 36.6 weeks with gestational diabetes mellitus and known status of antepartum corticosteroid exposure. The primary outcome, a composite neonatal adverse outcome, included Apgar score <5 at 5 minutes, immediate assisted ventilation, assisted ventilation >6 hours, surfactant use, seizure, or neonatal mortality. The secondary outcome was a composite maternal adverse outcome, including maternal blood transfusion, ruptured uterus, unplanned hysterectomy, and admission to the intensive care unit. Multivariable Poisson regression models were used to estimate adjusted relative risks and 95% confidence intervals. Average annual percent change was calculated to assess changes in rates of corticosteroid exposure over the study period.

RESULTS

Of 19 million births during the study period, 110,197 (0.6%) met the inclusion criteria, and among them, 23,028 (20.9%) individuals with gestational diabetes mellitus received antenatal corticosteroids. The rate of antenatal steroid exposure remained stable over the 5 years (APC=10.7; 95% confidence interval, -5.4 to 29.4). The composite neonatal adverse outcome was significantly higher among those who received corticosteroids than among those who did not (137.1 vs 216.5 per 1000 live births; adjusted relative risk 1.24; 95% confidence interval, 1.20-1.28). Three components of the composite neonatal adverse outcome-immediate assisted ventilation, intubation >6 hours, and surfactant use-were significantly higher with exposure than without. In addition, the composite maternal adverse outcome was significantly higher among those who received corticosteroids (adjusted relative risk, 1.34; 95% confidence interval, 1.18-1.52). Three components of the composite maternal adverse outcome-admission to intensive care unit, blood transfusion, and unplanned hysterectomy-were significantly higher among the exposed group. Subgroup analysis, among large for gestational age, by gestational age, and race and ethnicity, confirm the trend of increased likelihood of adverse outcomes with exposure to corticosteroid.

CONCLUSION

Individuals with gestational diabetes mellitus and antenatal corticosteroid exposure, who delivered in the late preterm, were at higher risk of neonatal and maternal adverse outcomes than those unexposed to corticosteroid.

Critical deterioration of chronic eosinophilic pneumonia during pregnancy

Chronic eosinophilic pneumonia (CEP) is a rare, idiopathic interstitial lung disease characterised by the accumulation of eosinophils in the pulmonary interstitia and alveoli. Patients with CEP respond well to systemic corticosteroid therapy and infrequently progress to end-stage lung disease. We report a case of a woman in her 40s with previously stable, steroid-responsive CEP who experienced a critical deterioration of her CEP at 25 weeks of gestation during her third pregnancy. The patient was admitted to the intensive care unit due to respiratory failure requiring intubation and mechanical ventilation. Follow-up investigation revealed advanced fibrotic lung disease requiring long-term oxygen therapy and referral for double lung transplantation. While CEP infrequently advances to permanent parenchymal damage, this case demonstrates the potential for severe exacerbations in the setting of pregnancy and highlights pregnancy as a potential risk factor for disease progression, reinforcing the need for further research to define optimal monitoring and treatment strategies.

Canadian Consensus Guidelines for the Diagnosis and Treatment of Autoimmune Encephalitis in Adults

Autoimmune encephalitis is increasingly recognized as a neurologic cause of acute mental status changes with similar prevalence to infectious encephalitis. Despite rising awareness, approaches to diagnosis remain inconsistent and evidence for optimal treatment is limited. The following Canadian guidelines represent a consensus and evidence (where available) based approach to both the diagnosis and treatment of adult patients with autoimmune encephalitis. The guidelines were developed using a modified RAND process and included input from specialists in autoimmune neurology, neuropsychiatry and infectious diseases. These guidelines are targeted at front line clinicians and were created to provide a pragmatic and practical approach to managing such patients in the acute setting.

Immunosuppressive and immunomodulating therapy for atopic dermatitis in pregnancy: an appraisal of the literature

Atopic dermatitis (AD) is the most common dermatological diagnosis during pregnancy. Treatment of AD during pregnancy can be challenging, due to the unpredictable course and the fact that the therapy needs to be safe for both the mother and the fetus. Here we present an up-to-date appraisal of the literature on the treatment options available for AD in patients planning pregnancy, during pregnancy, and during breastfeeding. All patients with AD are recommended to supplement any medical treatment with daily applications of emollients. The first step in the medical treatment for AD during pregnancy are topical corticosteroids, and/or topical tacrolimus. If required, UV-light therapy can also be considered. Treatment with systemic therapy during pregnancy should always rely on a careful risk-benefit assessment and be based on shared-decision making between the treating physician and patient. The first-line systemic treatment option is cyclosporine A, whereas azathioprine may be considered in patients already receiving this treatment prior to pregnancy. Systemic glucocorticoids may also be used. Treatment with systemic JAK inhibitors is not recommended, whereas treatment with mycophenolate mofetil and methotrexate is contraindicated. Targeted therapy with dupilumab is not generally recommended, due to lack of experience in human pregnancies, yet some case-reports on their use are emerging. These recommendations are based on the authors appraisal of existing literature and the current recommendation from the European Task Force on Atopic Dermatitis. It is always the responsibility of the treating physician to stay updated on the newest guidelines and literature when treating patients with AD during pregnancy.

Risks and outcomes of pregnancy in neuromyelitis optica spectrum disorder: A comprehensive review

Neuromyelitis optica spectrum disorder (NMOSD) is a rare central nervous system autoimmune disease. Aquaporin-4 antibody (AQP4-IgG) is present in over 75% of cases and criteria also exist for the diagnosis of seronegative NMOSD. AQP4-IgG NMOSD has a strong female predominance (9:1 ratio), with a median onset age of 40 years. Pregnancy in those with NMOSD is therefore an important topic. Fecundity in NMOSD is likely impaired, and for females who conceive, obstetric complications including miscarriages and pre-eclampsia are significantly higher in NMOSD compared to the general population and in related conditions such as multiple sclerosis (MS). In contrast to MS, NMOSD disease activity does not subside during pregnancy. Also, relapse risk substantially rises above pre-pregnancy rates in the early postpartum period. In view of the evolving landscape of NMOSD, we provide a contemporary update of the impacts of pregnancy in NMOSD.

Evolution of Fetal Growth in Symptomatic Sars-Cov-2 Pregnancies

INTRODUCTION

SARS-CoV-2 is a viral disease with potentially devastating effects. Observational studies of pregnant women infected with SARS-CoV-2 report an increased risk for FGR. This study utilizes data from a prospective SARS-CoV-2 registry in pregnancy, investigating the progression of fetuses to fetal growth restriction (FGR) at birth following maternal SARS-CoV-2 and evaluating the hypothesis of whether the percentage of SGA at birth is increased after maternal SARS-CoV-2 taking into account the time interval between infection and birth.

MATERIALS & METHODS

CRONOS is a prospective German registry enrolling pregnant women with confirmed SARS-CoV-2 infection during their pregnancy. SARS-CoV-2 symptoms, pregnancy- and delivery-specific information were recorded. The data evaluated in this study range from March 2020 until August 2021. Women with SARS-CoV-2 were divided into three groups according to the time of infection/symptoms to delivery: Group I<2 weeks, Group II 2-4 weeks, and Group III>4 weeks. FGR was defined as estimated and/or birth weight<10% ile, appropriate for gestational age (AGA) was within 10 and 90%ile, and large for gestational age (LGA) was defined as fetal or neonatal weight>90%ile.

RESULTS

Data for a total of 2,650 SARS-CoV-2-positive pregnant women were available. The analysis was restricted to symptomatic cases that delivered after 24+0 weeks of gestation. Excluding those cases with missing values for estimated fetal weight at time of infection and/or birth weight centile, 900 datasets remained for analyses. Group I consisted of 551 women, Group II of 112 women, and Group III of 237 women. The percentage of changes from AGA to FGR did not differ between groups. However, there was a significantly higher rate of large for gestational age (LGA) newborns at the time of birth compared to the time of SARS-CoV-2 infection in Group III (p=0.0024), respectively.

CONCLUSION

FGR rates did not differ between symptomatic COVID infections occurring within 2 weeks and>4 weeks before birth. On the contrary, it presented a significant increase in LGA pregnancies in Group III. However, in this study population, an increase in the percentage of LGA may be attributed to pandemic measures and a reduction in daily activity.

Non-Infectious Uveitis and Pregnancy, is There an Optimal Treatment? Uveitis Course and Safety of Uveitis Treatment in Pregnancy

In pregnancy, a plethora of factors causes changes in maternal immunity. Uveitis flare-ups are more frequent in the first trimester and in undertreated patients. Management of non-infectious uveitis during pregnancy remains understudied. A bibliographic review to consolidate existing evidence was performed by a multidisciplinary group of Ophthalmologists, Gynaecologists and Rheumatologists. Our group recommends initial management with minimum-required doses of corticosteroids, preferably locally, to treat intraocular inflammation whilst ensuring good neonatal outcomes. If ineffective, clinicians should consider addition of Cyclosporine, Azathioprine or Certolizumab pegol, which are seemingly safe in pregnancy. Other therapies (such as Methotrexate, Mycophenolate Mofetil and alkylating agents) are teratogenic or have a detrimental effect on the foetus. Furthermore, careful multidisciplinary preconception discussions and close follow-up are recommended, monitoring for flare-ups and actively tapering medication doses, with a primary endpoint focused on protecting ocular tissues from inflammation, whilst giving minimal risk of poor pregnancy and foetal outcomes.

Updating an Overview of Teratology

In this chapter, the authors aim to update an overview of the principles of teratology, beginning with the definition of teratology, the critical point at which this process occurs, and some of the most common etiological agents that improve our understanding of teratology.Modern teratology has greatly improved in recent years with advances in new methods in molecular biology, toxicology, animal laboratory science, and genetics, increasing our knowledge of ambient influences. Nevertheless, there is a lot to do to reduce the influence of hazardous intervening agents, whether they target our genetics or not, that can negatively affect pregnancy and induce congenital development disorders, including morphological, biochemical, or behavioral defects.Certain agents might indeed be related to certain defects, but we have not been able to identify the cause of most congenital defects, which highlights the importance of finding and testing out new genetics techniques and conducting laboratory animal science to unravel the etiology and pathogenicity of each congenital defect.

Liver Transplantation for Acute Liver Failure During Pregnancy: Case Report and Literature Review

Liver failure during pregnancy is a rare and highly fatal condition frequently resulting from the patient's pre-existing chronic liver disease. There is no established protocol for managing this condition, and physicians tend to adopt a conservative approach due to concerns about the impact of liver transplantation on fetal development. However, conservative treatment may exacerbate the condition, increasing the risk of fetal and miscarriage deaths. In this study, we present a case of acute-on-chronic liver failure resulting from chronic hepatitis during the 19th week of gestation. Despite undergoing conservative treatment, the fetus tragically died, but the patient achieved an excellent clinical outcome after emergency liver transplantation. We also conducted a systematic review of the literature on liver transplantation during pregnancy from the last decade, examining the causes of liver failure and transplantation during pregnancy. Our research complied with the principles outlined in the Declaration of Helsinki and the Istanbul Declaration.

Bell's palsy in pregnancy: A scoping review of risk factors, treatment and outcomes

Objective

There are limited studies reporting on Bell's palsy and pregnancy. Our study aimed to evaluate risk factors, current treatment options and facial function outcomes in women who developed Bell's palsy in pregnancy. To our knowledge this is the first review analyzing these factors.

Data sources/review methods

A search of PubMed/MEDLINE, Embase, Web of Sciences and Scopus was carried out. Studies describing risk factors, treatment and/or facial function outcomes of Bell's palsy in pregnancy were included. PRISMA-Scr guidelines were followed.

Results

The search yielded 392 abstracts, of which 15 studies were included for analysis. It was not possible to perform a meta-analysis due to small numbers and quality of studies. There were 559 patients included from the 15 studies. The third trimester was the most common time for Bell's palsy to occur (n = 364, 65%). Pre-eclampsia was the most common co-morbidity reported. The most common treatment was corticosteroids and the majority of patients had a complete recovery of their palsy (58%, n = 192).

Conclusion

This analysis has evaluated all available data concerning risk factors, treatment and facial function outcomes of BP in pregnancy. The third trimester is the most common time for Bell's palsy to occur in pregnancy. There is currently a lack of high quality evidence into this condition in pregnancy.

Pregnancy and Inflammatory Rheumatological Diseases: A Single-Center Retrospective Cohort Study

Background Rheumatic diseases pose risks to pregnant women, leading to complications like preterm birth, congenital heart block, and pregnancy loss. These diseases are expected to deteriorate during pregnancy and further in the postpartum period. The impact of these diseases on the pregnancy will add further burden on the patient, fetus, physician, and healthcare system. Advances in diagnosis and treatment have improved outcomes making them similar to that of healthy women, but close follow-up in a multidisciplinary clinic is essential. The objective of this study is to study the outcome of pregnancy in women with rheumatological disease and the behavior of the disease during pregnancy. Methods A retrospective cohort study was conducted in King Abdulaziz Medical City (KAMC) in Riyadh, Saudi Arabia, to compare the outcomes of pregnancy across three rheumatological diseases: Sjogren syndrome (SS), systemic lupus erythematosus (SLE), and rheumatoid arthritis (RA) from 2016 to 2021. A total of 128 pregnancies in 107 women with rheumatological diseases were included in this study. Pregnancy measures and outcomes were investigated by assessing maternal health, fetal health, and pregnancy complications, specifically maternal disease activity, medications to control the disease, infection, preterm birth, birth weight, abortions/stillbirths, mode of delivery, bleeding, preeclampsia, congenital heart block, and neonatal lupus. Results There were 55 patients with RA (63 RA pregnancies), 44 with SLE (54 SLE pregnancies), and eight with primary SS (11 SS pregnancies). In most of the pregnancies (n= 108; 95.58%), the patients were in clinical remission before pregnancy. Lupus nephritis, which was in remission before pregnancy, has been reported in nine (16.67%) out of 54 SLE pregnancies. Vaginal delivery was the most common mode of delivery (n=87; 67.97%). On the other hand, there were 38 cesarean sections (29.69%). Rheumatological disease flares occurred in 10 pregnancies (7.87%). One hundred and twenty-two live births were delivered. Preterm infants were born in 25 pregnancies (20.16%), and 16 (13.22%) of the newborns needed neonatal intensive care unit (NICU) care. Interestingly, congenital heart block (CHB) was found in five (12.2%) neonates out of 41 anti-SS-related antigen A (anti-SSA) positive mothers; one of those five died from heart block. Eleven neonates were delivered with positive serology, and five were diagnosed with neonatal lupus. Conclusion The outcome of pregnancy in patients with rheumatological disease is favorable. A multidisciplinary team approach and close clinical follow-up are the cornerstone for such success. A small dose of prednisolone (5 mg or less) is safe and will not have a negative impact on maternal or fetal health. CHB is a concern for pregnant women with positive anti-SSA.

IBD and Motherhood: A Journey through Conception, Pregnancy and Beyond

Inflammatory Bowel Disease (IBD) presents distinct challenges during pregnancy due to its influence on maternal health and pregnancy outcomes. This literature review aims to dissect the existing scientific evidence on pregnancy in women with IBD and provide evidence-based recommendations for clinical management. A comprehensive search was conducted across scientific databases, selecting clinical studies, systematic reviews, and other pertinent resources. Numerous studies have underscored an increased risk of complications during pregnancy for women with IBD, including preterm birth, low birth weight, neonates small for gestational age, and congenital malformations. Nevertheless, it's evident that proactive disease management before and throughout pregnancy can mitigate these risks. Continuation of IBD treatment during pregnancy and breastfeeding is deemed safe with agents like thiopurines, anti-TNF, vedolizumab, or ustekinumab. However, there's a call for caution when combining treatments due to the heightened risk of severe infections in the first year of life. For small molecules, their use is advised against in both scenarios. Effective disease management, minimizing disease activity, and interdisciplinary care are pivotal in attending to women with IBD. The emphasis is placed on the continual assessment of maternal and infant outcomes and an expressed need for further research to enhance the understanding of the ties between IBD and adverse pregnancy outcomes.

EASL Clinical Practice Guidelines on the management of liver diseases in pregnancy

Liver diseases in pregnancy comprise both gestational liver disorders and acute and chronic hepatic disorders occurring coincidentally in pregnancy. Whether related to pregnancy or pre-existing, liver diseases in pregnancy are associated with a significant risk of maternal and fetal morbidity and mortality. Thus, the European Association for the Study of Liver Disease invited a panel of experts to develop clinical practice guidelines aimed at providing recommendations, based on the best available evidence, for the management of liver disease in pregnancy for hepatologists, gastroenterologists, obstetric physicians, general physicians, obstetricians, specialists in training and other healthcare professionals who provide care for this patient population.

Maternal Risk Factors for Congenital Vertebral Anomalies: A Population-Based Study

BACKGROUND

The spectrum of congenital vertebral defects varies from benign lesions to severe, life-threatening conditions. The etiology and maternal risk factors remain mainly unclear in isolated cases. Hence, we aimed to assess and identify potential maternal risk factors for these anomalies. Based on previous studies, we hypothesized that maternal diabetes, smoking, advanced maternal age, obesity, chronic diseases, and medication used during the first trimester of pregnancy might increase the risk of congenital vertebral malformations.

METHODS

We performed a nationwide register-based case-control study. All cases with vertebral anomalies (including live births, stillbirths, and terminations for fetal anomaly) were identified in the Finnish Register of Congenital Malformations from 1997 to 2016. Five matched controls from the same geographic region were randomly selected for each case. Analyzed maternal risk factors included age, body mass index (BMI), parity, smoking, history of miscarriages, chronic diseases, and prescription drugs dispensed during the first trimester of pregnancy.

RESULTS

In total, 256 cases with diagnosed congenital vertebral anomalies were identified. After excluding 66 malformations associated with known syndromes, 190 nonsyndromic malformation cases were included. These were compared with 950 matched controls. Maternal pregestational diabetes was a significant risk factor for congenital vertebral anomalies (adjusted odds ratio [OR], 7.30 [95% confidence interval (CI), 2.53 to 21.09). Also, rheumatoid arthritis (adjusted OR, 22.91 [95% CI, 2.67 to 196.40]), estrogens (adjusted OR, 5.30 [95% CI, 1.57 to 17.8]), and heparins (adjusted OR, 8.94 [95% CI, 1.38 to 57.9]) were associated with elevated risk. In a sensitivity analysis using imputation, maternal smoking was also significantly associated with an elevated risk (adjusted OR, 1.57 [95% CI, 1.05 to 2.34]).

CONCLUSIONS

Maternal pregestational diabetes and rheumatoid arthritis increased the risk of congenital vertebral anomalies. Also, estrogens and heparins, both of which are frequently used in assisted reproductive technologies, were associated with an increased risk. Sensitivity analysis suggested an increased risk of vertebral anomalies with maternal smoking, warranting further studies.

Elevated third trimester corticosteroid levels are associated with fewer offspring infections

Respiratory infections are a leading cause of morbidity and mortality in early life, and recurrent infections increase the risk of developing chronic diseases. The maternal environment during pregnancy can impact offspring health, but the factors leading to increased infection proneness have not been well characterized during this period. Steroids have been implicated in respiratory health outcomes and may similarly influence infection susceptibility. Our objective was to describe relationships between maternal steroid levels and offspring infection proneness. Using adjusted Poisson regression models, we evaluated associations between sixteen androgenic and corticosteroid metabolites during pregnancy and offspring respiratory infection incidence across two pre-birth cohorts (N = 774 in VDAART and N = 729 in COPSAC). Steroid metabolites were measured in plasma samples from pregnant mothers across all trimesters of pregnancy by ultrahigh-performance-liquid-chromatography/mass-spectrometry. We conducted further inquiry into associations of steroids with related respiratory outcomes: asthma and lung function spirometry. Higher plasma corticosteroid levels in the third trimester of pregnancy were associated with lower incidence of offspring respiratory infections (P = 4.45 × 10-7 to 0.002) and improved lung function metrics (P = 0.020-0.036). Elevated maternal androgens were generally associated with increased offspring respiratory infections and worse lung function, with some associations demonstrating nominal significance at P < 0.05, but these trends were inconsistent across individual androgens. Increased maternal plasma corticosteroid levels in the late second and third trimesters were associated with lower infections and better lung function in offspring, which may represent a potential avenue for intervention through corticosteroid supplementation in late pregnancy to reduce offspring respiratory infection susceptibility in early life.Clinical Trial Registry information: VDAART and COPSAC were originally conducted as clinical trials; VDAART: ClinicalTrials.gov identifier NCT00920621; COPSAC: ClinicalTrials.gov identifier NCT00798226.

Obstetric and Gynecologic Disorders and the Nervous System

OBJECTIVE

This article discusses obstetric and gynecologic associations with common neurologic disorders.

LATEST DEVELOPMENTS

Neurologic complications of obstetric and gynecologic disorders can arise throughout the lifespan. Caution should be exercised when prescribing fingolimod and natalizumab to patients with multiple sclerosis who are of childbearing potential because of the risk of disease rebound when they are discontinued. OnabotulinumtoxinA is considered safe in pregnancy and lactation based on long-term observational data. Hypertensive disorders of pregnancy are associated with higher subsequent cerebrovascular risk, likely via multiple mechanisms.

ESSENTIAL POINTS

Neurologic disorders may present in a variety of obstetric and gynecologic contexts, with meaningful implications for recognition and treatment. These interactions must be considered when treating women with neurologic conditions.

A framework for testing pathways from prenatal stress-responsive hormones to cardiovascular disease risk

Cardiovascular disease (CVD) is a leading cause of death globally, with the prevalence projected to keep rising. Risk factors for adult CVD emerge at least as early as the prenatal period. Alterations in stress-responsive hormones in the prenatal period are hypothesized to contribute to CVD in adulthood, but little is known about relations between prenatal stress-responsive hormones and early precursors of CVD, such as cardiometabolic risk and health behaviors. The current review presents a theoretical model of the relation between prenatal stress-responsive hormones and adult CVD through cardiometabolic risk markers (e.g., rapid catch-up growth, high BMI/adiposity, high blood pressure, and altered blood glucose, lipids, and metabolic hormones) and health behaviors (e.g., substance use, poor sleep, poor diet and eating behaviors, and low physical activity levels). Emerging evidence in human and non-human animal literatures suggest that altered stress-responsive hormones during gestation predict higher cardiometabolic risk and poorer health behaviors in offspring. This review additionally highlights limitations of the current literature (e.g., lack of racial/ethnic diversity, lack of examination of sex differences), and discusses future directions for this promising area of research.

Pharmacotherapy for Sydenham's chorea: where are we and where do we need to be?

INTRODUCTION

Sydenham's chorea (SC) is the most common cause of acquired chorea in children. The existing literature describes it as a benign, self-remitting condition. However, recent evidence discloses the persistence of long-course neuropsychiatric and cognitive complications in adulthood, which imposes to redefine the concept of 'benignity' of such condition. In addition, therapies are mostly empirical and non-evidence based.

AREAS COVERED

Here, we conducted an electronic exploration of the PubMed database and selected 165 relevant studies directly correlated to SC treatment. Critical data from selected articles were synthesized to provide an update on pharmacotherapy in SC, which basically consists of three pillars: antibiotic, symptomatic and immunomodulant treatments. Moreover, since SC mostly affects females with recurrences occurring in pregnancy (chorea gravidarum), we focused on the management in pregnancy.

EXPERT OPINION

SC is still a major burden in developing countries. The first therapeutic strategy should be the primary prevention of group A beta-hemolytic streptococcal (GABHS) infection. Secondary antibiotic prophylaxis should be performed in every SC patient as the World Health Organization (WHO) guidelines recommend. Symptomatic or immunomodulant treatments are administered according to clinical judgment. However, a greater effort to understand SC physiopathology is needed, together with larger trials, to outline appropriate therapeutic indications.

Adverse birth outcomes and early-life infections after in utero exposure to corticosteroids for inflammatory bowel disease: a Danish nationwide cohort study

BACKGROUND

Systemic corticosteroids are often used to treat inflammatory bowel disease (IBD) flares during pregnancy as maintenance of disease remission is crucial to optimize pregnancy outcomes. However, there is little data regarding the effect of in utero exposure to corticosteroids on the risk of adverse birth outcomes and early-life infections in the offspring.

METHODS

We used the Danish national registries to establish a nationwide cohort of all singleton live births in women with IBD from 1995 to 2015. Outcomes in children exposed in utero to corticosteroids were compared to those who were not exposed. In logistic and Cox proportional hazard regression models, we adjusted the outcomes (major congenital malformation, preterm birth, small for gestational age, low 5-min Apgar score, and infections) for confounders such as body mass index, smoking, comorbidity, and additional medical IBD treatment.

RESULTS

After in utero exposure to corticosteroids at any time between 30 days prior to conception through the first trimester (n = 707), the adjusted hazard ratio of major congenital malformation was 1.28 (95% CI: 0.82-2.00) compared to children born to women with IBD, but not exposed to corticosteroids in utero (n = 9371). After in utero exposure to corticosteroids at any time during pregnancy (n = 1336), the adjusted odds ratios for preterm birth, small for gestational age, and low 5-min Apgar score were 2.45 (95% CI: 1.91-3.13), 1.21 (95% CI: 0.76-1.90), and 0.91 (95% CI: 0.33-2.52), respectively. Finally, the adjusted hazard ratio of overall infections in the first year of life was 1.14 (95% CI: 0.94-1.39).

CONCLUSIONS

This nationwide cohort study suggests that children of women with IBD exposed to corticosteroids in utero had an almost 2.5-fold increased risk of preterm birth. Use of corticosteroids is closely related to disease activity and we cannot adjust for the independent role of disease activity. It is however reassuring that the other examined birth and early-life outcomes were not statistically significantly increased.

Inflammatory bowel disease in pregnancy and breastfeeding

Inflammatory bowel disease (IBD) has a peak age of diagnosis before the age of 35 years. Concerns about infertility, adverse pregnancy outcomes, and heritability of IBD have influenced decision-making for patients of childbearing age and their care providers. The interplay between the complex physiology in pregnancy and IBD can affect placental development, microbiome composition and responses to therapy. Current evidence has shown that effective disease management, including pre-conception counselling, multidisciplinary care and therapeutic agents to minimize disease activity, can improve pregnancy outcomes. This Review outlines the management of IBD in pregnancy and the safety of IBD therapies, including novel agents, with regard to both maternal and fetal health. The vast majority of IBD therapies can be used with low risk during pregnancy and lactation without substantial effects on neonatal outcomes.

Prolonged maternal exposure to glucocorticoids alters selenoprotein expression in the developing brain

Aberrant activation of the stress-response system in early life can alter neurodevelopment and cause long-term neurological changes. Activation of the hypothalamic-pituitary-adrenal axis releases glucocorticoids into the bloodstream, to help the organism adapt to the stressful stimulus. Elevated glucocorticoid levels can promote the accumulation of reactive oxygen species, and the brain is highly susceptible to oxidative stress. The essential trace element selenium is obtained through diet, is used to synthesize antioxidant selenoproteins, and can mitigate glucocorticoid-mediated oxidative damage. Glucocorticoids can impair antioxidant enzymes in the brain, and could potentially influence selenoprotein expression. We hypothesized that exposure to high levels of glucocorticoids would disrupt selenoprotein expression in the developing brain. C57 wild-type dams of recently birthed litters were fed either a moderate (0.25 ppm) or high (1 ppm) selenium diet and administered corticosterone (75 μg/ml) via drinking water during postnatal days 1 to 15, after which the brains of the offspring were collected for western blot analysis. Glutathione peroxidase 1 and 4 levels were increased by maternal corticosterone exposure within the prefrontal cortex, hippocampus, and hypothalamus of offspring. Additionally, levels of the glucocorticoid receptor were decreased in the hippocampus and selenoprotein W was elevated in the hypothalamus by corticosterone. Maternal consumption of a high selenium diet independently decreased glucocorticoid receptor levels in the hippocampus of offspring of both sexes, as well as in the prefrontal cortex of female offspring. This study demonstrates that early life exposure to excess glucocorticoid levels can alter selenoprotein levels in the developing brain.

COVID-19 Pharmacotherapy in Pregnancy: A Literature Review of Current Therapeutic Choices

The clinical management of COVID-19 in pregnant women, who are considered a vulnerable population, remains uncertain even as the pandemic subsides. SARS-CoV-2 affects pregnant individuals in multiple ways and has been associated with severe maternal morbidity and mortality, as well as neonatal complications. The unique anatomy and physiology of gestation make managing COVID-19 in this population a complex and challenging task, emphasizing the importance of spreading knowledge and expertise in this area. Therapeutic interventions require distinct clinical consideration, taking into account differences in pharmacokinetics, vertical transmission, drug toxicities, and postnatal care. Currently, there is limited data on antiviral and immunomodulating COVID-19 pharmacotherapy in pregnancy. Some medication has been shown to be safe and well tolerated among pregnant women with COVID-19; however, the lack of randomized clinical trials and studies in this patient population is evident. Available vaccines are considered safe and effective, with no evidence of harm to the fetus, embryo development, or short-term postnatal development. Pregnant women should be counseled about the risks of SARS-CoV-2 infection and informed of available ways to protect themselves and their families. Effective treatments for COVID-19 should not be withheld from pregnant individuals, and more research is needed to ensure the best outcomes.

Maternal and fetal outcomes in pregnant women with rheumatoid arthritis: a systematic review and meta-analysis

OBJECTIVE

Rheumatoid arthritis (RA) is a common chronic systemic autoimmune disease affecting women of childbearing age. We aimed to conduct a meta-analysis of published observational studies to systematically evaluate the association between RA and adverse pregnancy outcomes.

METHODS

Medline (PubMed), EMBASE, and Web of Science were searched for keywords from the date of inception to December 28, 2021, to identify relevant studies reporting adverse maternal and/or fetal outcomes in RA pregnancies. Data from individual studies were pooled using random-effects models and presented as odds ratios (ORs) with 95% confidence intervals (CIs).

RESULTS

Eighteen studies with a total number of over 50 million participants were eligible for inclusion. This current analysis showed that in pregnant women with RA, there was a significantly increased risk of adverse maternal outcomes, including caesarean section (OR, 1.39; 95% CI 1.24-1.55), pre-eclampsia (OR, 1.48; 95% CI 1.19-1.83), gestational hypertension (OR, 1.34; 95% CI 1.07-1.68) and spontaneous abortion (OR, 1.16; 95% CI 1.04-1.29). Similarly, maternal RA during pregnancy was also associated with a significantly increased risk of adverse fetal outcomes, including preterm birth (OR, 1.58; 95% CI 1.44-1.74), small for gestational age (OR, 1.49; 95% CI 1.22-1.82), low birth weight (OR, 1.45; 95% CI 1.30-1.63), congenital anomalies (OR, 1.36; 95% CI 1.01-1.83) and stillborn (OR, 1.38; 95% CI 1.09-1.74).

CONCLUSION

Maternal RA is significantly associated with an increased risk of adverse maternal and fetal outcomes. Close monitoring of the clinical status of RA patients before and during pregnancy is essential in clinical practice. Key Points • Pregnant women with rheumatoid arthritis (RA) are at significantly increased risk for adverse maternal and fetal outcomes. • The increased risk of adverse pregnancy outcomes in women with RA may be closely related to medication use and disease activity. • Close monitoring of the clinical status of RA patients before and during pregnancy is essential in clinical practice.

Acquired haemophilia A diagnosed during pregnancy

Pregnancy-associated haemophilia A is an uncommon, acquired bleeding disorder which usually presents post-partum; very rarely it may present during pregnancy. No consensus guidelines exist on the management of this condition in pregnancy and very few cases have been reported in the literature. Here we describe the case of a woman presenting with acquired haemophilia A during pregnancy and outline the management of her bleeding disorder. We contrast her case with that of two other women, presenting to the same tertiary referral centre, with acquired haemophilia A presenting post-partum. These cases highlight the heterogeneous management of this condition and how it may be successfully managed in pregnancy.

CORRELATION BETWEEN INFLAMMATORY FOCI REACTIVATION AND ATROPHY GROWTH IN EYES WITH IDIOPATHIC MULTIFOCAL CHOROIDITIS

PURPOSE

To correlate the number of inflammatory reactivations in atrophic foci of multifocal choroiditis (MFC) with their growth rate over a 4-year span.

METHODS

Comparative case series. Optical coherence tomography scans of patients affected by MFC were reviewed to identify reactivations within or at the margin of atrophic MFC foci. The area of selected lesions was semiautomatically delineated on fundus autofluorescence images and recorded at yearly intervals for a total follow-up of 4 years. The main outcome was the difference in annual square-root transformed area growth rate between lesions that reactivated and lesions that did not.

RESULTS

Sixty-six foci of 30 eyes of 24 patients were included. All MFC foci enlarged over time, but the annual growth rate was more than double in lesions that reactivated compared with those that did not (mean [SD], 0.051 [0.035] vs. 0.021 [0.015] mm/year, P < 0.001), despite starting from comparable baseline areas. For each additional inflammatory reactivation, the annual growth rate increased by more than 20% (+0.009 mm/year, 95% CI [0.006, 0.012], P < 0.001).

CONCLUSION

Increasing number of reactivations of atrophic foci led to proportional increments in their growth rate, highlighting the need for a tight control of inflammatory relapses in patients affected by MFC.

Study of the Mechanisms and Therapeutic Approaches of Migraine in Women and Pregnancy: A Literature Review

Headache is a significant and debilitating health problem, affecting more than half of the population worldwide. Migraine is a type of headache that is strongly associated with women and accounts for the high number of years lived with disability among women. The pathophysiology of migraine attacks may begin with a premonitory phase, followed by an aura phase and migraine headache. In women, many factors influence the prevalence of migraine, and sex hormone fluctuations around the menstruation cycle were believed to impact the pathogenesis of migraine. The International Classification of Headache Disorders, 3rd edition identifies menstrual migraine as pure menstrual migraine without aura and menstrually related migraine without aura. While migraine without aura (MwoA) was clearly associated with menstruation, migraine with aura (MwA) was generally unrelated to menstruation. Studies suggested that estrogen withdrawal is a trigger for MwoA, but high estrogen states are a trigger for MwA. During pregnancy, the increase in estrogen hypothetically prevents migraine attacks. There are several strategies for managing menstrual migraine, from acute/abortive, mini-preventive, and continuous preventive treatment. Managing migraine during pregnancy follows a similar strategy, but the drugs' safety profile should be considered.

Anaphylaxis in Pregnancy

Anaphylaxis in pregnancy is a rare event, but has important implications for the pregnant patient and fetus. The epidemiology, pathophysiology, diagnosis, and treatment all carry important considerations unique to the pregnant patient. Common culprits of anaphylaxis are primarily medications, particularly antibiotics and anesthetic agents. Diagnosis can be difficult given the relative lack of cutaneous symptoms, and normal physiologic changes in pregnancy such as low blood pressure and tachycardia. Apart from patient positioning, treatment is similar to that of the general population, with a focus on prompt epinephrine administration.

Neuroimmunological Disorders

Multiple sclerosis is a disease that tends to affect women during their childbearing years. Although relapse risk decreases during pregnancy, patients should still be optimized on disease-modifying therapy before and after pregnancy to minimize gaps in treatment. Exclusive breastfeeding may reduce the chances of disease relapse postpartum, and many disease-modifying therapies are considered to be safe while breastfeeding. Treatments for other neuroimmunologic disorders such as neuromyelitis optica spectrum disorder, myelin oligodendrocyte glycoprotein antibody-associated disease, neurosarcoidosis, and central nervous system vasculitis may require rituximab before and prednisone or intravenous immunoglobulin therapy during pregnancy.

Pharmacoethics and pregnancy: Overcoming the therapeutic orphan stigma

There is paucity of evidence to support clinical decision making and counselling related to medication use in pregnancy. Despite multiple efforts from legislative bodies and advocacy groups, the inclusion of pregnant women in clinical drug trials assessing efficacy and safety remains scarce. Pregnancy can be complicated by multiple comorbidities that require pharmacological intervention; these interventions primarily target the pregnant woman but also sometimes have secondary effects for the foetus. The US Food and Drug Administration has issued multiple guidance documents on incorporating pregnant women in clinical trials to aid pharmaceutical companies in designing a protocol to ensure safety and adherence to ethical standards. Advances in paediatric pharmacology studies provide lessons for researchers on the best practice of designing clinical trials with inclusion of patients from special populations. In this review, we present the status of pregnant women in clinical trials, highlighting the ethical stigma and possible future directives.

Outcomes of Prospectively Followed Pregnancies in Rheumatoid Arthritis: A Multicenter Study from Romania

Women with rheumatoid arthritis (RA) may carry an increased risk of adverse pregnancy outcomes (APO). The aims of this study were to compare pregnancy outcomes in RA patients as compared to the general obstetric population (GOP) and to identify a risk profile in RA. A case-control study was conducted on 82 prospectively followed pregnancies in RA and 299 pregnancies from the GOP. The mean age at conception was 31.50 ± 4.5 years, with a mean disease duration of 8.96 ± 6.3 years. The frequency of APO in RA patients was 41.5%, 18.3% experienced spontaneous abortions, 11.0% underwent preterm deliveries, 7.3% had small for gestational age infants, 4.9% experienced intrauterine growth restriction, 1.2% experienced stillbirth, and 1.2% suffered from eclampsia. The risk of APO was correlated with a maternal age higher than 35 years (p = 0.028, OR = 5.59). The rate of planned pregnancies was 76.8%, and the subfertility rate was 4.9%. Disease activity improved every trimester, and approximately 20% experienced an improvement in the second trimester. Planned pregnancies and corticosteroids use (≤10 mg daily) were protective factors for APO in RA pregnancies (p < 0.001, OR = 0.12, p = 0.016, OR = 0.19, respectively). There was no significant association between APO and disease activity or DMARDs used before and during pregnancy. Regarding the comparison between the RA group and the controls, RA mothers were significantly older (p = 0.001), had shorter pregnancies (p < 0.001), and had neonates with a lower birth weight (p < 0.001).

Inflammatory Bowel Disease in the Childbearing Adult and Newborn

Inflammatory bowel disease (IBD) often affects people in their childbearing years and has implications for pregnancy outcomes, particularly as related to increased risk of preterm delivery and effects of immunosuppressive medications on the fetus. Ideally, people with IBD should attempt conception at a time when their disease is in remission to optimize pregnancy outcomes and reduce risks of flares. Generally, pregnant individuals should continue immunosuppressive medications throughout gestation in an attempt to control the disease. Maternal risks of IBD in pregnancy include exacerbated anemia, disease flare, cesarean delivery, and treatment risks. Fetal and neonatal risks include preterm birth, low birthweight, and medication exposures. There are too few clinical trials that include pregnant or breastfeeding patients to analyze the risk/benefit profile of immunosuppressive medications for IBD treatment during pregnancy, limiting the amount of data available to guide medical treatment in this population. More studies are needed on IBD therapies, particularly as more biologics are developed and become the mainstay of treatment. Neonatal clinicians should be aware of in utero medication exposure to help guide decisions regarding newborn care.

A review of COVID-19 therapeutics in pregnancy and lactation

Pregnant people have an elevated risk of severe COVID-19-related complications compared to their non-pregnant counterparts, underscoring the need for safe and effective therapies. In this review, we summarize published data on COVID-19 therapeutics in pregnancy and lactation to help inform clinical decision-making about their use in this population. Although no serious safety signals have been raised for many agents, data clearly have serious limitations and there are many important knowledge gaps about the safety and efficacy of key therapeutics used for COVID-19. Moving forward, diligent follow-up and documentation of outcomes in pregnant people treated with these agents will be essential to advance our understanding. Greater regulatory push and incentives are needed to ensure studies to obtain pregnancy data are expedited.

Treatment of Acne Vulgaris During Pregnancy and Lactation: A Narrative Review

Acne vulgaris frequently affects women during pregnancy and lactation. Hormonal and physiologic changes in pregnancy contribute to the pathogenesis of acne during the various phases of pregnancy. Several effective acne treatments commonly prescribed in the general population are contraindicated during pregnancy or lactation. There is a lack of guidelines and updated resources on acne management in these populations. In this narrative review, we summarize existing evidence on the safety and efficacy of acne treatments during pregnancy and breastfeeding. Acne management in pregnancy and lactation should follow a stepwise approach based on severity to minimize risk. Topical therapies, such as benzoyl peroxide, azelaic acid, or keratolytics, can be used to treat mild-to-moderate disease. Moderate-to-severe acne may require systemic treatments, including penicillin, amoxicillin, cephalexin, and erythromycin, with special consideration for trimester-specific teratogenicity of medications and relevant medical history of the mother and infant. For refractory cases, oral or intralesional corticosteroids as well as laser and light therapies may be considered. This review provides an updated reference to aid patient-physician decision-making on acne management in these special populations.

COVID-19-related medicine utilization study in pregnancy: The COVI-PREG cohort

AIM

The objective of this study was to describe the use of COVID-19-related medicines during pregnancy and their evolution between the early/late periods of the pandemic.

METHODS

Pregnant women who tested positive for SARS-CoV-2 from March 2020 to July 2021 were included using the COVI-PREG registry. Exposure to the following COVID-19-related medicines was recorded: antibiotics, antivirals, hydroxychloroquine, corticosteroids, anti-interleukin-6 and immunoglobulins. We described the prevalence of medicines used, by trimester of pregnancy, maternal COVID-19 severity level and early/late period of the pandemic (before and after 1 July 2020).

FINDINGS

We included 1964 pregnant patients who tested positive for SARS-CoV-2. Overall, 10.4% (205/1964) received at least one COVID-19-related medicine including antibiotics (8.6%; 169/1694), corticosteroids (3.2%; 62/1964), antivirals (2.0%; 39/1964), hydroxychloroquine (1.4%; 27/1964) and anti-interleukin-6 (0.3%; 5/1964). The use of at least one COVID-19-related medicine was 3.1% (12/381) in asymptomatic individuals, 4.2% (52/1233) in outpatients, 19.7% (46/233) in inpatients without oxygen, 72.1% (44/61) in those requiring standard oxygen, 95.7% (22/23) in those requiring high flow oxygen, 96.2% (25/26) in patients who required intubation and 57.1% (4/7) among patients who died. The proportion who received medicines to treat COVID-19 was higher before than after July 2020 (16.7% vs. 7.7%). Antibiotics, antivirals and hydroxychloroquine had lower rates of use during the late period.

CONCLUSION

Medicine use in pregnancy increased with disease severity. The trend towards increased use of corticosteroids seems to be aligned with changing guidelines. Evidence is still needed regarding the effectiveness and safety of COVID-19-related medicines in pregnancy.

Gene×environment associations in orofacial clefting

This chapter reviews the evidence of gene×environment interactions (G×E) in the etiology of orofacial cleft birth defects (OFCs), specifically cleft lip (CL), cleft palate (CP), and cleft lip with or without cleft palate (CL/P). We summarize the current state of our understanding of the genetic architecture of nonsyndromic OFCs and the evidence that maternal exposures during pregnancy influence risk of OFCs. Further, we present possible candidate gene pathways for these exposures including metabolism of folates, metabolism of retinoids, retinoic acid receptor signaling, aryl hydrocarbon receptor signaling, glucocorticoid receptor signaling, and biotransformation and transport. We review genes in these pathways with prior evidence of association with OFCs, genes with evidence from prior candidate gene G×E studies, and genes identified from genome-wide searches specifically for identifying G×E. Finally, we suggest future directions for G×E research in OFCs.
