First trimester exposure to corticosteroids and oral clefts

Increased prevalence of negative pregnancy and fetal outcomes in women with primary adrenal insufficiency. A systematic review and meta-analysis

Maternal primary adrenal insufficiency (PAI) during pregnancy, due to either Addison disease (AD) or congenital adrenal hyperplasia (CAH), is rare. Only few studies have examined the subsequent important outcomes of maternal glucocorticoid and mineralocorticoid deficiencies during pregnancy upon the fetus and the neonate. Therefore, this systematic review and meta-analysis evaluated the impact of these deficiencies, with data from PubMed/Medline, Cochrane/CENTRAL, and Google Scholar. A total of 31 studies were included for qualitative analysis and 11 for quantitative analysis. Studies examining the prevalence of spontaneous abortion, preterm birth, the occurrence of small for gestational age (SGA) neonates, as well as the neonatal birth weight were included. The systematic review revealed a substantial number of spontaneous abortions, preterm births and SGA neonates in pregnant women with PAI. The meta-analysis showed a mean spontaneous abortion prevalence of 18%, 18% and 17% in women with PAI, AD or CAH, respectively. The mean preterm birth prevalence was 11% when women with AD or CAH were analyzed together, and 13% and 9% in women with AD or CAH, respectively, when these women were analyzed separately. The mean prevalence of SGA neonates was 8% when women with AD or CAH were analyzed together, and 5% and 10% in women with AD or CAH, respectively, when these women were analyzed separately. The mean fetal birth weight was within normalcy in all women with PAI, as well as in women with AD or CAH. In conclusion the executed systematic review of 31 studies followed by a meta-analysis of 11 studies in pregnant women with PAI has shown a greater prevalence of pregnancies with negative outcome (spontaneous abortion, preterm birth) and of negative fetal outcome (SGA) in women with either AD or CAH, as compared to control pregnant women.

Inflammatory Bowel Disease and Reproductive Health: A Focus on Pregnancy Planning and Outcomes

Reproductive counseling is crucial for women's health, especially for those with inflammatory bowel disease (IBD), which often affects younger patients during their childbearing years. Patients with IBD need special considerations when planning for pregnancy. Preconception counseling is important as it helps patients make informed decisions about pregnancy and allows for optimal management of IBD before, during, and after pregnancy. In this review, we aim to provide guidance for managing and treating patients with IBD throughout the preconception, pregnancy, and postpartum period.

Medication use before and during pregnancy in Japan: the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study

PURPOSE

To elucidate the status of medication use among pregnant women in Japan, by means of a multigenerational genome and birth cohort study: the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study (TMM BirThree Cohort Study).

METHODS

Questionnaires were distributed to pregnant women participating in the TMM BirThree Cohort Study (from July 2013 to March 2017) around 12 weeks (early pregnancy) and 26 weeks (middle pregnancy). We analysed medication use over three periods: (1) 12 months prior to pregnancy diagnosis, (2) the period between pregnancy diagnosis and around week 12 of pregnancy, and (3) post around week 12 of pregnancy.

RESULTS

In total, 19,297 women were included in the analysis. The proportion of pregnant women using medications was 49.0% prior to pregnancy diagnosis, 52.1% from diagnosis to week 12, and 58.4% post week 12 of pregnancy. The most frequently prescribed medications were loxoprofen sodium hydrate (5.5%) prior to pregnancy diagnosis, magnesium oxide (5.9%) from diagnosis to week 12, and ritodrine hydrochloride (10.5%) post week 12 of pregnancy. The number of women who used suspected teratogenic medications during early pregnancy was 96 prior to pregnancy diagnosis, 48 from diagnosis to week 12, and 54 post week 12 of pregnancy.

CONCLUSION

We found that ~ 50% of the pregnant women used medications before and during pregnancy and some took potential teratogenic medications during pregnancy. In birth genomic cohort study, it is expected that investigations into the safety and effectiveness of medications used during pregnancy will advance.

Characteristics of Factors Influencing the Occurrence of Cleft Lip and/or Palate: A Case Analysis and Literature Review

INTRODUCTION

Cleft lip with or without cleft palate (CL/P) stands as the most common congenital facial anomaly, stemming from multifactorial causes.

OBJECTIVE

Our study aimed to ascertain the prevalence and characteristics of cleft palates, identify associated risk factors to inform prevention and prenatal detection for early intervention, and assess postoperative rehabilitation protocols for cleft palates.

DESIGN

This study employs a retrospective descriptive and clinical approach.

PATIENTS

The study includes 103 children with cleft palates treated at the Department of Head and Neck Surgery Clinic for Children and Young Adults, Department of Clinical Pediatrics, University of Warmia and Mazury.

METHODS

We conducted a thorough evaluation of records, considering variables such as sex, cleft type, maternal occupation, parental education, and family history of clefts. Data analysis was carried out using R software version GPL-3 and ordinal logistic regression analyses.

RESULTS

Notably, children born to mothers who experienced significant stress during pregnancy exhibited a 9.4-fold increase in the odds of having bilateral cleft palates. Conversely, no substantial evidence was found to support the influence of the child's sex, birth order, body mass, maternal exposure to workplace toxins, infections, or drug toxicity on the dependent variable.

CONCLUSIONS

Our findings suggest that children with parents who have a history of clefts and those with less educated mothers are more likely to develop bilateral cleft palates. Additionally, children born to mothers experiencing stress during pregnancy face an increased risk of bilateral cleft palates. It is important to note that there is a paucity of literature on rehabilitation following various cleft palate surgical techniques in children.

Safety of Antenatal Predniso(lo)ne and Dexamethasone on Fetal, Neonatal and Childhood Outcomes: A Systematic Review

CONTEXT

Due to ethical considerations, antenatal dose finding for prednisolone and dexamethasone in pregnant women is limited, leading to a knowledge gap.

OBJECTIVE

In order to guide the clinician in weighing benefits vs risks, the aim is to systematically review the current literature on the side effects of antenatal predniso(lo)ne and dexamethasone use on the fetus, newborn, and (pre)pubertal child.

EVIDENCE ACQUISITION

The search was performed in PubMed/MEDLINE and Embase using prespecified keywords and Medical Subject Headings. This systematic review investigated studies published until August 2022, with the following inclusion criteria: studies were conducted in humans and assessed side effects of long-term antenatal predniso(lo)ne and dexamethasone use during at least one of the trimesters on the child during the fetal period, neonatal phase, and during childhood.

EVIDENCE SYNTHESIS

In total, 328 papers in PubMed and 193 in Embase were identified. Fifteen studies were eligible for inclusion. Seven records were added through references. Antenatal predniso(lo)ne use may be associated with lower gestational age, but was not associated with miscarriages and stillbirths, congenital abnormalities, differences in blood pressure or low blood glucose levels at birth, or with low bone mass, long-term elevated cortisol and cortisone, or high blood pressure at prepubertal age. Increased risks of antenatal dexamethasone use include association with miscarriages and stillbirths, and from age 16 years, associations with disturbed insulin secretion and higher glucose and cholesterol levels.

CONCLUSIONS

Based on the limited evidence found, predniso(lo)ne may have less side effects compared with dexamethasone in short- and long-term outcomes. Current literature shows minimal risk of side effects in the newborn from administration of a prenatal predniso(lo)ne dose of up to 10 mg per day.

Association of Commonly Prescribed Antepartum Medications and Incidence of Orofacial Clefting

BACKGROUND

Pharmacologic agents are often used in the antepartum period, however, studies on their effect on fetal development are limited. Thus, this study aims to examine the effect of commonly prescribed antepartum medications on the development of orofacial clefting.

METHODS

Utilizing EPIC Cosmos deidentified data from approximately 180 US institutions was queried. Patients born between January 1, 2013, to January 1, 2023, were included. Eight OC cohorts were identified. Gestational medication use was identified by medications prescribed, provider-administered, or reported use by mothers. Medications used in at least 1 in 10,000 pregnancies were included in this analysis.

RESULTS

A total of 12 098 newborns with available maternal pharmacologic data were born with any type of orofacial clefting. Prevalence for all oral clefts, any cleft palate, and any cleft lip were 20.56, 18.10, and 10.60 per 10 000 individuals, respectively. Notable significant exposures include most anticonvulsants, such as lamotrigine (OR1.33, CI 1.10-1.62), and topiramate (OR1.35, CI 1.13-1.62), as well as nearly all SSRIs/SNRIs, including fluoxetine (OR1.34, CI 1.19-1.51), sertraline (OR1.25, CI 1.16-1.34), and citalopram (OR1.28, CI 1.11-1.47). Corticosteroids were also correlated including dexamethasone (OR1.19, CI 1.12-1.27), and betamethasone (OR1.64, CI 1.55-1.73), as were antibiotics, including amoxicillin (OR1.22, CI 1.14-1.30), doxycycline (OR1.29, CI 1.10-1.52), and nitrofuran derivatives (OR1.10, CI 1.03-1.17).

CONCLUSION

New associations between commonly prescribed antepartum medications and orofacial clefting were found. These findings should be confirmed as causality is not assessed in this report. Practitioners should be aware of the potential increased risk associated with these medications.

Clinical Pharmacology in Sarcoidosis: How to Use and Monitor Sarcoidosis Medications

When sarcoidosis needs treatment, pharmacotherapy is usually required. Although glucocorticoids work reliably and relatively quickly for sarcoidosis, these drugs are associated with numerous significant side effects. Such side effects are common in sarcoidosis patients, as the disease frequently has a chronic course and glucocorticoid treatment courses are often prolonged. For these reasons, corticosteroid-sparing and corticosteroid-replacing therapies are often required for sarcoidosis. Unfortunately, many healthcare providers who care for sarcoidosis patients are not familiar with the use of these agents. In this manuscript, we provide a review of the pharmacotherapy of sarcoidosis. We discuss the mechanism of action, dosing, side-effect profile, approach to monitoring and patient counselling concerning glucocorticoids, and the common alternative drugs recommended for use in the recent European Respiratory Society (Lausanne, Switzerland) Sarcoidosis Treatment Guidelines. We also discuss the use of these agents in special situations including hepatic insufficiency, renal insufficiency, pregnancy, breastfeeding, vaccination, and drug-drug interactions. It is hoped that this manuscript will provide valuable practical guidance to clinicians who care for sarcoidosis patients.

Occupational and environmental noise exposure during pregnancy and rare health outcomes of offspring: a scoping review focusing on congenital anomalies and perinatal mortality

As environmental and occupational noise can be health hazards, recent studies have investigated the effects of noise exposure during pregnancy. Despite biological plausibility and animal studies supporting an association, studies focusing on congenital anomalies and perinatal mortality as outcomes of noise exposure are still scarce. We performed a scoping review to collect, summarise, and discuss the existing scientific research about the relationships between noise exposure during pregnancy and congenital anomalies and/or perinatal mortality. We searched electronic databases for papers published between 1970 and March 2021. We included 16 studies (seven on congenital anomalies, three on perinatal mortality, and two on both congenital anomalies and perinatal mortality). We assessed four studies on congenital hearing dysfunction as the definition of congenital anomalies includes functional anomalies. We found few studies on this topic and no studies on the combined effects of occupational and environmental noise exposures. Evidence suggests a small increase in the risk of congenital anomalies in relation to occupational and to a lesser extent environmental noise exposure. In addition, few studies investigated perinatal mortality and the ones that did, used different outcome definitions, so no conclusions could be made. However, a recent big cross-sectional study demonstrated an association between road traffic noise and stillbirth. A few studies suggest a possible association between congenital hearing dysfunction and occupational noise exposure during pregnancy. Future studies with larger samples, better exposure assessments, and better statistical modelling strategies are needed to investigate these relationships further.

Maternal Common Cold or Fever During Pregnancy and the Risk of Orofacial Clefts in the Offspring: A Systematic Review and Meta-analysis

The common cold and/or an associated fever during pregnancy have/has been suspected to harm the developing fetus. We sought possible correlations between a maternal common cold or fever during pregnancy and the risk of orofacial clefts in the offspring.

We systematically searched PubMed and Embase using appropriate keywords, and we checked the reference lists of retrieved articles. We used random-effects models to estimate overall relative risks.

Incidence of orofacial clefts.

We included 13 case-control studies. Modest but statistically significant associations were found between a maternal common cold and cleft lip with or without a cleft palate (CL/CP) (odds ratio [OR] 2.17; 95% confidence interval [CI] 1.66-2.83) and a cleft palate only (CPO) (OR 3.08; 95% CI 1.5-6.34). Furthermore, maternal fever was also associated with an increased risk of CL/CP (OR 1.91, 95% CI 1.3-2.8) and CPO (OR 1.48, 95% CI 0.83-2.63) in the offspring. Further analyses of maternal influenza (alone) yielded similar results.

Although evidence of heterogeneity should be carefully evaluated, our findings suggest that maternal common cold or fever during pregnancy may be associated with a greater risk of CL/CP or CPO in the offspring. Future cohort studies using valid assessments of maternal common cold exposure during pregnancy that consider the severity of fever are needed to clarify the contribution of maternal common cold or fever status to the risk of orofacial clefts in children.

MicroRNAs and Gene Regulatory Networks Related to Cleft Lip and Palate

Cleft lip and palate is one of the most common congenital birth defects and has a complex etiology. Either genetic or environmental factors, or both, are involved at various degrees, and the type and severity of clefts vary. One of the longstanding questions is how environmental factors lead to craniofacial developmental anomalies. Recent studies highlight non-coding RNAs as potential epigenetic regulators in cleft lip and palate. In this review, we will discuss microRNAs, a type of small non-coding RNAs that can simultaneously regulate expression of many downstream target genes, as a causative mechanism of cleft lip and palate in humans and mice.

Pregnancy outcomes after early fetal exposure to injectable first-line treatments, dimethyl fumarate, or natalizumab in Danish women with multiple sclerosis

BACKGROUND AND PURPOSE

Data on pregnancy outcomes following fetal exposure to disease-modifying drugs (DMDs) in women with multiple sclerosis (MS) are sparse although growing.

METHODS

Data from the Danish Multiple Sclerosis Registry were linked with nationwide registries enabling an investigation of adverse pregnancy outcomes in newborns of women with MS following fetal exposure to injectable first-line treatments, dimethyl fumarate, glatiramer acetate, or natalizumab. Logistic regression models accounting for clustered data were used to estimate odds ratios (ORs) with 95% confidence intervals (CIs) for individual and composite adverse outcomes after adjusting for relevant covariates.

RESULTS

A total of 1009 DMD-exposed pregnancies were compared with 1073 DMD-unexposed pregnancies as well as 91,112 pregnancies from the general population. No association of an increased risk of any perinatal outcome was found when comparing newborns with fetal exposure with the general population, including preterm birth (OR = 1.19, 95% CI = 0.86-1.64), small for gestational age (OR = 1.38, 95% CI = 0.92-2.07), spontaneous abortion (OR = 1.04, 95% CI = 0.84-1.27), congenital malformation (OR = 0.99, 95% CI = 0.68-1.45), low Apgar score (OR = 0.62, 95% CI = 0.23-1.65), stillbirth (OR = 1.05, 95% CI = 0.33-3.31), placenta complication (OR = 0.53, 95% CI = 0.22-1.27), and any adverse event (OR = 1.10, 95% CI = 0.93-1.30). Similar results were found when comparing DMD-exposed pregnancies with DMD-unexposed pregnancies.

CONCLUSIONS

We found no increased association of adverse pregnancy outcomes in newborns with fetal exposure to DMDs when compared with either DMD-unexposed pregnancies or the general population.

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.

A case of minimal change disease during pregnancy - benefits of early diagnosis and use of corticosteroids

Nephrotic syndrome presenting in pregnancy is rare and poses a diagnostic and therapeutic challenge. Timing of renal biopsy is important given the increased risk of bleeding and miscarriage, and the choice of immunosuppression is limited due to the teratogenicity profiles of standard drugs. We report and discuss a case of minimal change disease diagnosed by renal biopsy during early pregnancy and treated with corticosteroids throughout the pregnancy. Prompt diagnosis and treatment of glomerular disease in pregnancy are vital to prevent poor maternal and fetal outcomes.

Exposure to corticosteroids in the first trimester is associated with an increased risk of urogenital congenital anomalies

STUDY QUESTION

Does maternal exposure to first trimester corticosteroids in IVF/ICSI treatment result in an increased risk of congenital anomalies?

SUMMARY ANSWER

Children born with the aid of IVF/ICSI whose mothers were treated with adjuvant corticosteroids during the first trimester had an increased risk of cryptorchidism, hypospadias and talipes.

WHAT IS KNOWN ALREADY

Maternal exposure to corticosteroids may increase the risk of congenital anomalies such as cleft palate and neural tube defects. However, the existing studies have conflicting outcomes, are underpowered, and do not study a population undergoing IVF/ICSI, a group known to be at increased risk of abnormalities.

STUDY DESIGN, SIZE, DURATION

This retrospective cohort analysis covering Monash IVF fertility clinics in Melbourne, Australia assessed the outcomes of 12 426 live births from both fresh and frozen embryo transfers between 2010 and 2016.

PARTICIPANTS/MATERIALS, SETTING, METHODS

There were 618 live births included in our study group of mothers exposed to corticosteroids (oral prednisolone or dexamethasone) during their IVF/ICSI treatment, with the remainder of births not exposed to steroids (control, n = 11 808). The primary outcome measured was the presence of congenital anomalies and secondary outcomes were birth weight and gestation length. Multivariate binary logistic regression was used to assess the independent effects of corticosteroid exposure and the freezing of embryos, with adjustment for maternal age at oocyte retrieval, smoking status, number of cycles taken, BMI, etiology of the infertility and the use of ICSI. Results are presented as incidence rate ratios (IRRs) with 95% CIs.

MAIN RESULTS AND THE ROLE OF CHANCE

Amongst 12 426 live births, and 597 birth defects, multivariate logistic regression demonstrated there was an increased incidence in talipes equinovarus (1.33% vs 0.32%, adjusted IRR = 4.30, 95% CI = 1.93, 9.58; P < 0.001), hypospadias (0.66% vs 0.18%, adjusted IRR = 5.90, 95% CI = 2.09, 16.69; P = 0.001) and cryptorchidism (0.83% vs 0.19%, adjusted IRR = 5.53, 95% CI = 1.91, 15.42; P = 0.001) in the offspring of mothers exposed to corticosteroids compared to those who were unexposed. The incidence of neither neural tube defects nor cleft palate were significantly increased in babies exposed to corticosteroids. The sex ratio of infants exposed to corticosteroids during a fresh embryo transfer cycle significantly favored males but reverted to the normal sex ratio in infants conceived in frozen embryo transfer cycles.

LIMITATIONS, REASONS FOR CAUTION

This was a retrospective observational cohort study using administrative datasets with the potential for measurement error and unobserved confounding. Missing outcome data were obtained from patients using self-report leading to possible ascertainment bias. Given the rare incidence of some of the anomalies assessed, the study was underpowered to identify differences in abnormality rates for some specific anomalies.

WIDER IMPLICATIONS OF THE FINDINGS

The findings of this study, the largest of its kind, suggest that caution should be heeded when prescribing corticosteroids to women undergoing IVF/ICSI, given that this study has now identified three previously unassociated serious neonatal complications (talipes, hypospadias and cryptorchidism), plus a potential alteration in sex ratio. Physicians should be careful in using corticosteroids in the critical first trimester and should counsel patients regarding the potential risks of this treatment.

STUDY FUNDING/COMPETING INTEREST(S)

There was no funding sought or obtained for this study. K.T., V.T., B.V. and D.Z.-F. are employees or contractors to Monash IVF and hold a minority stock position in Monash IVF. R.J.W. reports no conflict of interest.

Management of Critically Ill Pregnant Patients with COVID-19 Infection in a Rural State

OBJECTIVE

There is limited data on the treatment of coronavirus disease 2019 (COVID-19) in pregnancy. Arkansas saw an increase in COVID-19 cases in June 2020. The first critically ill pregnant patient was admitted to our institution on May 21^st, 2020. The objective of this study was to evaluate outcomes in critically ill pregnant women with COVID-19 at a single tertiary care center who received remdesivir and convalescent plasma (CCP).

STUDY DESIGN

This is a retrospective observational review of critically ill pregnant women with COVID-19 who received remdesivir and CCP. This study was approved by the institutional review board (#261354).

RESULTS

Seven pregnant patients with COVID-19 were admitted to the intensive care unit (ICU). All received remdesivir and CCP. Six received dexamethasone. The median ICU length of stay (LOS) was 8 days (range 3-17). Patient 1 had multi-organ failure requiring vasopressors, renal dialysis, and had an intrauterine fetal demise. Patients 4 and 6 required mechanical ventilation, were delivered for respiratory distress and were extubated at 2 and 1 days postpartum, respectively. The only common risk factor was obesity. There were no adverse events noted with remdesivir or CCP.

CONCLUSION

There is little data regarding the use of remdesivir or CCP for the treatment of COVID-19 in pregnant women. In our cohort, these were well tolerated with no adverse events. Previously reported median ICU LOS in critically ill pregnant women with COVID-19 was 8 days (range 4-15).1 Our study found a similar ICU LOS (8 days; range 3-17). Patient 1 did not receive remdesivir or CCP until transport to our facility on hospital day 3. Excluding patient 1, median ICU LOS was 6.5 days (range 3-9). Our institution's treatment of pregnant women with critical illness with remdesivir, CCP and dexamethasone combined with delivery in select cases has thus far had good outcomes.

KEY POINTS

· Combined therapy: remdesivir, CCP, dexamethasone.. · Remdesivir, CCP and dexamethasone was effective in treating critically ill pregnant women with COVID-19.. · No adverse events were associated with combined therapy.. · Delivery improved respiratory status..

A review of pruritus in pregnancy

Pruritus is a common dermatologic complaint during pregnancy. Pruritus is reported by 23-38% of women during pregnancy, and 2% report severe pruritus. In addition to interfering with sleep and reducing overall quality of life during pregnancy, pruritus may be the first, or only, symptom of an underlying disorder that may impact maternal and fetal outcomes. It is therefore critical for all providers caring for pregnant women to be familiar with pregnancy-specific and non-specific conditions associated with pruritus to most effectively manage this unique population. In this review, we discuss clinical classification of pruritus, a practical approach to the differential diagnosis of pruritus in pregnancy, and focus on updates in the clinical features, diagnosis, management, and prognosis of pregnancy-specific causes of pruritus.

Glucocorticoids for therapeutic immunosuppression: Clinical pearls for the practicing neurologist

Given widespread use of glucocorticoid therapy in neurologic disease, understanding glucocorticoid pharmacology and risk is paramount for the practicing neurologist. While dosing and tapering regimens vary depending on the neurological disease and indication being treated, there are important general principles of glucocorticoid prescribing and monitoring that can guide clinical decision-making. Glucocorticoid-related toxicities can occur across multiple organ systems, including hypertension; dyslipidemia; weight gain; hyperglycemia; osteoporosis and avascular necrosis; myopathy; gastrointestinal bleeding; infection; and neuropsychiatric effects with sleep, mood disturbance and cognition. This narrative review provides a practical framework for safe and responsible prescribing of this therapeutic class of medications, including appreciation of immunosuppressive consequences, risk mitigation strategies, dosing and tapering, and recognition of adrenal insufficiency and glucocorticoid withdrawal.

Impact of Parental Consanguinity on the Frequency of Orofacial Clefts in Jordan

ABSTRACT

Orofacial clefts (OFCs) are the most common craniofacial congenital anomalies, and its prevalence is highest among Asian populations. The aim of this retrospective case-control study is to evaluate the effect of parental consanguinity on the frequency of OFCs at Jordan University Hospital over a 15-year-period. The study group consists of all patients with OFCs presented to the major tertiary referral center in Jordan during the last 15 years, along with age and gender-matched controls. The authors analyzed the risk of different predictors, including consanguinity, on the development of OFCs, both cleft lip with or without cleft palate (CL/P) and cleft palate only. A total of 332 participants were included in this study, with a mean age of 74.36 (±48.75) months. The authors included 129 (38.9%) OFCs, and 203 (61.1%) controls. The percentage of parental consanguinity among OFCs group was 41.1%, compared to only 24.1% for controls, a difference that was statistically significant (P = 0.001). On logistic regression analysis, the authors found that parental consanguinity is a significant predictor for the occurrence of OFCs (P = 0.007), where people with consanguineous marriage have 2 times higher risk (odds ratio of 0.504, with 95% confidence interval 0.306-0.830) to have offspring with OFCs. Moreover, lower birth weight babies are also significantly more associated with OFCs (P = 0.014), with an odds ratio of 1.819 (95% confidence interval 1.131 2.926). Among the Jordanian population, the authors found that consanguinity and lower birth weight were the only variables significantly associated with the development of OFCs.

Available medications used as potential therapeutics for COVID-19: What are the known safety profiles in pregnancy

BACKGROUND

Medications already available to treat other conditions are presently being studied in clinical trials as potential treatments for COVID-19. Given that pregnant women are excluded from these trials, we aimed to investigate their safety when used during pregnancy within a unique population source.

METHODS

Using the population-based Quebec Pregnancy Cohort, we identified women who delivered a singleton liveborn (1998-2015). Taking potential confounders into account including indications for use, the risk of prematurity, low birth weight (LBW), small for gestational age (SGA), and major congenital malformation (MCM) associated with COVID-19 repurposed drug use during pregnancy were quantified using generalized estimation equations.

RESULTS

Of the 231,075 eligible pregnancies, 107 were exposed to dexamethasone (0.05%), 31 to interferons (0.01%), 1,398 to heparins (0.60%), 24 to angiotensin-receptor blockers (ARB) (0.01%), 182 to chloroquine (0.08%), 103 to hydroxychloroquine (0.05%), 6,206 to azithromycin (2.70%), 230 to oseltamivir (0.10%), and 114 to HIV medications (0.05%). Adjusting for potential confounders, we observed an increased risk of prematurity related to dexamethasone (aOR 1.92, 95%CI 1.11-3.33; 15 exposed cases), anti-thrombotics (aOR 1.58, 95%CI 1.31-1.91; 177 exposed cases), and HIV medications (aOR 2.04, 95%CI 1.01-4.11; 20 exposed cases) use. An increased risk for LBW associated with anti-thrombotics (aOR 1.72, 95%CI 1.41-2.11; 152 exposed cases), and HIV medications (aOR 2.48, 95%CI 1.25-4.90; 21 exposed cases) use were also found. Gestational exposure to anti-thrombotics (aOR 1.20, 95%CI 1.00-1.44; 176 exposed cases), and HIV medications (aOR 2.61, 95%CI 1.51-4.51; 30 exposed cases) were associated with SGA. First-trimester dexamethasone (aOR 1.66, 95%CI 1.02-2.69; 20 exposed cases) and azithromycin (aOR 1.10, 95%CI 1.02-1.19; 747 exposed cases) exposures were associated with MCM.

CONCLUSIONS

Many available medications considered as treatments for COVID-19 are associated with adverse pregnancy outcomes. Caution is warranted when considering these medications during the gestational period.

Pregnancy and medications in inflammatory bowel disease

Inflammatory bowel disease (IBD) affects patients at a significant time in their lives, often coinciding with family planning or pregnancy. While advances in IBD therapies have afforded women greater opportunities for successful conception and pregnancy outcomes, there still remains considerable maternal fear surrounding continuation of treatment in pregnancy. With the exception of methotrexate, most IBD drugs are safe and well tolerated during pregnancy and are not associated with significant risk of adverse fetal or pregnancy outcomes. Furthermore, the current evidence overwhelmingly suggests that good control of disease activity and clinical remission at time of conception are the greatest prognostic factors for an uncomplicated pregnancy and maintenance of quiescent disease. Management of pregnant women with IBD should involve discussions with the mother and family about fears or concerns surrounding the impact of IBD on pregnancy. Mothers should be supported and counselled carefully on the safety and importance of adherence to therapy in maintaining remission. Optimal management of these women requires an inter-disciplinary team effort, involving the general practitioner, in close consultation with both gastroenterologists and obstetricians.

Orofacial clefts embryology, classification, epidemiology, and genetics

Orofacial clefts (OFCs) rank as the second most common congenital birth defect in the United States after Down syndrome and are the most common head and neck congenital malformations. They are classified as cleft lip with or without cleft palate (CL/P) and cleft palate only (CPO). OFCs have significant psychological and socio-economic impact on patients and their families and require a multidisciplinary approach for management and counseling. A complex interaction between genetic and environmental factors contributes to the incidence and clinical presentation of OFCs. In this comprehensive review, the embryology, classification, epidemiology and etiology of clefts are thoroughly discussed and a "state-of-the-art" snapshot of the recent advances in the genetics of OFCs is presented.

Management Considerations for Recalcitrant Hyperemesis

Importance

Hyperemesis gravidarum (HEG) affects 0.3% to 3% of pregnancies and requires additional therapies beyond those commonly used for less severe instances of nausea and vomiting of pregnancy (NVP). Differentiating between NVP and HEG is a vital yet challenging function for any obstetrician. The literature for management of HEG is lacking compared with that of NVP.

Objective

Review etiology of NVP/HEG highlights key considerations in the workup of HEG as they compare to NVP and explore management options for recalcitrant HEG focusing principally on how they affect maternal and fetal outcomes and secondarily on where data are nonprescriptive.

Evidence Acquisition

This was a literature review primarily using PubMed and Google Scholar.

Results

Short-course corticosteroids and treatment for Helicobacter pylori have the most favorable risk-reward profiles of the 4 pharmacologic therapies evaluated. Mirtazapine and diazepam may have a place in highly selected patients. If nutritional supplementation is required, enteral nutrition is strictly preferred to parenteral nutrition. Postpyloric feeding approaches are less likely to induce vomiting. Surgically placed feeding tubes are less likely to be dislodged and may be worth the invasive insertion procedure if nasogastric or nasojejunal tubes are not tolerated.

Conclusions and Relevance

Hyperemesis gravidarum is a diagnosis reserved for refractory cases of NVP and therefore by definition poses treatment challenges. Any clinical presentation that lent itself to prescriptive, algorithmic management would likely fall short of the diagnostic criteria for HEG. However, data can inform management on a patient-by-patient basis or at least help patient and provider understand risks and benefits of therapies reserved for refractory cases.

Oral corticosteroids during pregnancy and offspring risk of congenital heart defects: a nationwide cohort study

BACKGROUND

Pre-pregnancy diabetes is a strong risk factor for congenital heart defects (CHDs), suggesting a role for glucose in the causal pathway. Oral corticosteroids may cause hyperglycemia and maternal use could affect embryonic heart development. The objective of this study was to determine the association between maternal intake of oral corticosteroids 0-8 weeks after conception and CHDs in offspring.

METHODS

A register-based nationwide prevalence study including all live singleton births in Denmark, 1996-2016, was conducted. In total, 1 194 687 individuals and their mothers were identified and linked with information on offspring CHDs and the mothers' use of oral corticosteroids in early pregnancy. Corticosteroid use was defined as a filled prescription for maternal use of oral corticosteroid 0-8 weeks after conception. CHDs were identified through International Classification of Diseases codes. The association was estimated by prevalence (odds) ratios using logistic regression and propensity score-matched analyses.

RESULTS

Among 1 194 687 live births, 2032 had a mother who had used oral corticosteroids 0-8 weeks from conception. Of these offspring, 32 had a heart defect. Among the offspring of never-users of oral corticosteroids, 10 534 had a heart defect. The adjusted prevalence ratio was 1.29 (95% confidence interval, 0.90-1.84) comparing offspring prevalence of heart defects in oral corticosteroid users with that in oral corticosteroid never-users. Propensity score-matched analysis yielded similar results (prevalence ratio 1.38; 95% confidence interval, 0.95-2.02).

CONCLUSIONS

This study supports that there is no association between maternal use of oral corticosteroids in the first 8 weeks after conception and CHDs.

Neuromyelitis optica spectrum disorders and pregnancy: therapeutic considerations

Neuromyelitis optica spectrum disorders (NMOSD) are a type of neurological autoimmune disease characterized by attacks of CNS inflammation that are often severe and predominantly affect the spinal cord and optic nerve. The majority of individuals with NMOSD are women, many of whom are of childbearing age. Although NMOSD are rare, several small retrospective studies and case reports have indicated that pregnancy can worsen disease activity and might contribute to disease onset. NMOSD disease activity seems to negatively affect pregnancy outcomes. Moreover, some of the current NMOSD treatments are known to pose risks to the developing fetus and only limited safety data are available for others. Here, we review published studies regarding the relationship between pregnancy outcomes and NMOSD disease activity. We also assess the risks associated with using disease-modifying therapies for NMOSD during the course of pregnancy and breastfeeding. On the basis of the available evidence, we offer recommendations regarding the use of these therapies in the course of pregnancy planning in individuals with NMOSD.

Management of immune thrombocytopenia in women: current standards and special considerations

Introduction: Immune thrombocytopenia (ITP) is an acquired autoimmune disorder, with an incidence rate of 20-40/million adults/year and an estimated prevalence in women of childbearing age of 24.5/million.Areas covered: Authors discuss management of ITP in pregnancy, treatment-related toxicity, delivery, neonatal thrombocytopenia and breastfeeding, and other women's specific issues. The search of papers published between January 1990 and December 2019 was done on PubMed using combinations of the keywords below. The distinction between ITP and other thrombocytopenias in pregnancy is of paramount importance. The current belief (at variance with the past) that ITP is a relatively benign disease pregnancy is emphasized.Expert opinion: The lack of randomized, prospective, controlled studies hampers evidence-based statements. Remarkably, ITP diagnosis is still one of exclusion, there are no clinical or laboratory criteria for prognosis and we still need more solid data on the risks related to neonatal thrombocytopenia. Corticosteroids and IVIG remain the mainstay of treatment, since rituximab, thrombopoietin-receptor agonists, fostamatinib may be toxic in pregnancy. Safety and efficacy of recombinant-human-thrombopoietin, available in China, require confirmation studies. Quality of life and women-related toxicity of treatments in young girls, adults, and elders are still an orphan area of investigation.

Benign and malignant tumors of the central nervous system and pregnancy

Tumors of the central nervous system (CNS) are rare entities, typically affecting the very young or the very old, but span a spectrum of disease that may present in any age group. Women of reproductive age are more likely to be affected by benign tumors, including pituitary adenomas and meningiomas, and aggressive intracranial malignancies, such as brain metastases and glioblastoma, rarely present in pregnancy. Definitive management of CNS tumors may involve multimodal therapy, including surgery, radiation, and chemotherapy, and each of these treatments carries risk to the mother and developing fetus. CNS tumors often present with challenging and morbid symptoms such as headache and seizure, which need to be managed throughout a pregnancy. Decisions about timing treatment during pregnancy or delaying until after delivery, continuing or electively terminating a pregnancy, and future family planning and fertility are complex and require a multidisciplinary care team to evaluate the implications to both mother and baby. There are no guidelines or consensus recommendations regarding brain tumor management in pregnancy, and thus, individual treatment decisions are made by the care team based on experiential evidence, extrapolation of guidelines for nonpregnant patients, and patient values and preferences.

Multi‑organ assessment via a 9.4‑Tesla MRS evaluation of metabolites during the embryonic development of cleft palate induced by dexamethasone

The aim of the present study was to determine the association between maternal metabolism and development of the fetal palate, and to suggest a potential non‑invasive prenatal diagnostic method for fetal cleft palate (CP). Dexamethasone (DXM) was used to create a CP mouse model. A 9.4‑Tesla (T) magnetic resonance spectroscopy (MRS) imager was used to measure an array of metabolites in the maternal serum, placental tissue, amniotic fluid and fetal palates. Multivariate statistical analysis was performed using SIMCA‑P 14.1 software. Following DXM treatment, variations were detected in multiple metabolites in the female mice and their fetuses based on 9.4T MRS. It was indicated that in the experimental group during CP formation, leucine, valine, creatine, acetate and citrate levels in the palatal tissue were lower, whereas lactate, alanine, proline/inositol and glutamate‑containing metabolite levels were higher, compared with the levels in the control group. In placental tissue and amniotic fluid, succinate and choline levels were lower in the experimental group. The relative concentrations of cholesterol and lipids in palatal tissues from mice treated with DXM were higher compared with the concentrations in tissues from mice in the control group, with the exception of (CH2)n lipids. In the placental tissue, the alteration in cholesterol level exhibited the opposite trend. Lipid levels for the different lipid forms varied and most of them were unsaturated lipids.

Maternal and fetal outcomes in pregnancies with long-term corticosteroid use

PURPOSE

Long-term corticosteroids are administered in pregnant patients with an array of autoimmune and inflammatory disorders. Our objective is to determine whether long-term corticosteroid use is associated with increased maternal and neonatal adverse outcomes.

MATERIALS AND METHODS

We performed a retrospective cohort study using the Healthcare Cost and Utilization Project-national Inpatient Sample from the USA. All pregnant patients on long-term corticosteroids were identified using International Classification of Disease-9 coding from 2003 to 2015. The effect of long-term corticosteroid use on maternal and neonatal outcomes was evaluated using multivariate logistic regression.

RESULTS

Out of the 10,491,798 births included in our study, 3999 were among women with long-term use of steroids, for an overall prevalence of 38 per 100,000 births. There was a steady increase in chronic steroid use from 2 to 81 per 100,000 births over the 13-year study period (p < .0001). Women on long-term steroids were more likely to have pregnancies complicated by preeclampsia, 1.72 (1.30-2.29) and were at greater risk of preterm premature rupture of membranes, 1.63 (1.01-2.44), pyelonephritis, 4.81 (1.18-19.61), and venous thromboembolisms, 2.50 (1.32-4.73). Neonates born from mothers on long-term steroids were more likely to suffer from prematurity, 1.51 (1.13-2.05), and lower weight for gestational age, 2.10 (1.34-3.30).

CONCLUSION

Long-term corticosteroids use in pregnancy is associated with maternal and fetal adverse outcomes. These patients would benefit from close follow-up throughout their pregnancy to minimize complications.

Management of autoimmune blistering diseases in pregnancy and the neonate

The management of autoimmune blistering diseases (AIBD) is therapeutically challenging, particularly in patients who plan to conceive, or are pregnant or breastfeeding. Not only is a patient's immune system altered by pregnancy-associated hormonal changes, but several medications used for AIBD treatment are not recommended for use in pregnancy or lactation. The data acquired regarding the safety and efficacy of these therapeutic interventions are gathered from studies or case reports from other diseases, as the treatment modalities are similar and randomized controlled trials are typically not performed in the setting of pregnancy. Although some medications for AIBD treatment are considered unsafe for use in pregnancy, many effective and tolerable therapies are able to provide benefit to these patients. In fact, most first-line agents may be used in pregnancy, to a given extent. This article discusses the medications used to treat AIBD prior to conception, during pregnancy, and while breastfeeding, as well as highlights those that are contraindicated. The preferred approach to management in these patients is also discussed. Additionally, we present the available information regarding neonates of mothers with a diagnosis of AIBD, including the likelihood, identification, and management of neonatal blistering and the effects from medication exposure in utero.

[Influence of dexamethasone on the cell polarity and PAR complex of the embryonic epithelial cells in the palate]

OBJECTIVE

This study aims to investigate whether dexamethasone (DEX) can down-regulate the PAR complex and disrupt the cell polarity in the palatal epithelium during palatal fusion.

METHODS

Pregnant rats were randomly divided into control and DEX groups, which were injected intraperitoneally with 0.9% sodium chloride (0.1 mL) and DEX (6 mg·kg ⁻¹), respectively, every day from E10 to E12. The palatal epithelial morphology was observed using hematoxylin and eosin staining and scanning electron microscopy. Immunofluorescence staining, Western Blot analysis, and real-time polymerase chain reaction were performed to detect the expression of PAR3, PAR6, and aPKC.

RESULTS

The incidence of cleft palate in DEX group (46.15%) was significantly higher than that in control group (3.92%), and the difference was statistically significant (χ2=24.335, P=0.00). DEX can also retard the growth of the palatal shelves and the short palatal shelves. The morphology and arrangement of MEE cells changed from polarized bilayer cells to nonpolarized monolayer ones. Additionally, the spherical structure decreased, which caused the cleft palate. PAR3 and PAR6 were only detected in the palatal epithelium, and aPKC was expressed in the palatal epithelium and mesenchyme. DEX can reduce the expression levels of PAR3, PAR6, and aPKC in the protein and gene levels.

CONCLUSIONS

DEX can down-regulate the complex gene expression in the MEE cells, thereby destroying the cell polarity and causing cleft palate.

Pharmacological Approach to Managing Childhood-Onset Systemic Lupus Erythematosus During Conception, Pregnancy and Breastfeeding

Pediatric patients often have poor pregnancy outcomes. Systemic lupus erythematosus predominantly impacts women in their second to fourth decade of life, with childhood-onset disease being particularly aggressive. Reproductive issues are an important clinical consideration for pediatric patients with systemic lupus erythematosus (SLE), as maintaining good disease control and planning a pregnancy are important for maternal and fetal outcomes. In this clinical review, we will consider the safety of medications in managing childhood-onset SLE during conception, pregnancy, and breastfeeding. The developing fetus is at highest risk for teratogenicity from maternal medications during the period of critical organogenesis, which occurs between the first 3-8 weeks following conception. Medications known to be teratogenic, leading to a specific pattern of malformations, include mycophenolic acid, methotrexate, and cyclophosphamide. These should be discontinued prior to a planned pregnancy or as soon as pregnancy is suspected. Hydroxychloroquine is safe and should be continued throughout pregnancy and breastfeeding in those without contraindications to it. Azathioprine and calcineurin inhibitors are felt to be compatible with pregnancy in usual doses and may be used prior to and throughout pregnancy and lactation. Non-fluorinated corticosteroids including methylprednisolone and prednisone are inactivated by the placenta and can be used if needed for maternal indication during gestation. Addition of aspirin may be considered around the 12th week of gestation for prevention of pre-eclampsia. Illustrative cases are presented that demonstrate management of adolescents with childhood-onset SLE through conception, pregnancy, and breastfeeding.

Maternal exposure to ambient air pollutant and risk of oral clefts in Wuhan, China

Maternal exposure to ambient air pollution has been related to oral clefts in offspring; however, the epidemiologic evidence is equivocal. Especially, the association between high levels of exposure to ambient air pollution during pregnancy and oral clefts remains unclear. The objective of this study was to evaluate whether high levels of maternal exposure to PM_2.5, PM₁₀, O₃, CO and SO₂ are related to increased risk of oral clefts in Wuhan, China. A population-based study was conducted using cohort of 105,927 live-born infants, fetal deaths, and stillbirths during a two-year period from 2011 to 2013. For each participant, weekly and monthly averages of daily mean concentrations for each pollutant were estimated. Multiple logistic regression analyses were constructed to quantify the adjusted odds ratios (aORs) for the relationship between each air pollutant and oral clefts while controlling for key covariates. Using monthly averages, a cleft lip with or without cleft palate (CLP) was associated with PM_2.5 (aORs _{2nd month} = 1.34, CI:1.19-1.49; aORs _{3rd month=}1.14, CI:1.02-1.28), PM₁₀ (aORs _{2nd month} = 1.11, CI:1.00-1.23) and CO (aORs _{2nd month} = 1.31, CI:1.14-1.51; aORs _{3rd month} = 1.17, CI:1.03-1.33). A cleft palate only (CPO) was associated with PM_2.5 (aORs _{2nd month} = 1.24, CI: 1.03-1.48), and O₃ (aORs _{2nd month} = 1.21, CI: 1.03-1.42; aORs _{3rd month} = 1.18, CI: 1.02-1.37). Our findings reveal an association between air pollutants exposure and the risk of oral clefts. Future studies are needed to confirm these associations, and clarify the causality related to specific pollutants during the most relevant vulnerable exposure time windows for oral clefts during pregnancy.

Use of azathioprine and corticosteroids during pregnancy and birth outcome in women diagnosed with inflammatory bowel disease

BACKGROUND

The aim of this study was to describe prescription patterns for azathioprine and corticosteroids for pregnant women with inflammatory bowel diseases (IBD) before, during, and after pregnancy and to describe pregnancy outcomes.

METHODS

A cohort composed of all singleton pregnancies in Danish registries from 1996 to 2009 was divided by maternal IBD status: Crohn's disease (CD, n = 827), ulcerative colitis (UC, N = 1361), or no IBD diagnosis (background population, n = 814,231). The number of women with a prescription for azathioprine, local and systemic steroids within a 3-month period was computed for each of the pregnancy trimesters and the year before and after pregnancy. Outcomes of interest were stillbirth, perinatal mortality, low birth weight (LBW), preterm birth, and small for gestational age (SGA).

RESULTS

Number of prescriptions for azathioprine decreased just before and during pregnancy and increased after birth. Number of prescriptions for local and systemic corticosteroids decreased approximately 30% compared with before pregnancy and increased in the second trimester. There was an increased risk among mothers with IBD of LBW (adjusted odds ratio [adjOR]: CD: 2.25 [95% confidence interval {CI}, 1.74-2.91], UC: 1.81 [95% CI, 1.42-2.30]), preterm birth (adjOR: CD: 2.54 [95% CI, 2.04-3.15], UC: 1.86 [95% CI, 1.52-2.27]), and SGA (adjOR: CD: 1.99 [95% CI, 1.26-3.15], UC: 1.80 [95% CI, 1.18-2.75]).

CONCLUSION

Use of azathioprine and corticosteroids was often reduced or discontinued before or during early pregnancy followed by an increased use of corticosteroids later in pregnancy. Women diagnosed with IBD and with prescriptions for azathioprine and/or corticosteroids, have an increased risk of LBW, pre-term birth, and SGA.

Sexuality, Fertility, and Pregnancy in Crohn's Disease

Many factors influence the sexual health of people with Crohn's disease, but active disease and depression play key roles. The fertility rate in nonoperated patients with inflammatory bowel disease with quiescent disease is similar to that in the general population. Crohn's disease can increase the risk for adverse pregnancy outcomes, but being in remission on a stable, steroid-free medication regimen for at least 3 months before conception and adhering to the treatment throughout pregnancy can improve outcomes. Infants with intrauterine exposure to anti-tumor necrosis factor medications should avoid live vaccines for the first 9 months or until drug concentrations are undetectable.

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

The evidence to date regarding corticosteroid exposure in pregnancy and select pregnancy and birth outcomes is limited and inconsistent. The authors provide a narrative review of published literature summarizing the findings for oral clefts, preterm birth, birth weight, preeclampsia, and gestational diabetes mellitus. Whenever possible, the results are limited to oral or systemic administration with a further focus on use in autoimmune disease. Although previous studies of corticosteroid exposure in pregnancy reported an increased risk of oral clefts in the offspring, more recent studies have not replicated these findings.

Treatment options for hyperemesis gravidarum

Hyperemesis gravidarum (HG) is a severe and prolonged form of nausea and/or vomiting during pregnancy. HG affects 0.3-2% of pregnancies and is defined by dehydration, ketonuria, and more than 5% body weight loss. Initial pharmacologic treatment for HG includes a combination of doxylamine and pyridoxine. Additional interventions include ondansetron or dopamine antagonists such as metoclopramide or promethazine. The options are limited for women who are not adequately treated with these medications. We suggest that mirtazapine is a useful drug in this context and its efficacy has been described in case studies. Mirtazapine acts on noradrenergic, serotonergic, histaminergic, and muscarinic receptors to produce antidepressant, anxiolytic, antiemetic, sedative, and appetite-stimulating effects. Mirtazapine is not associated with an independent increased risk of birth defects. Further investigation of mirtazapine as a treatment for HG holds promise to expand treatment options for women suffering from HG.

Psoriasis in those planning a family, pregnant or breast-feeding. The Australasian Psoriasis Collaboration

The Australasian Psoriasis Collaboration has reviewed the evidence for managing moderate to severe psoriasis in those who are pregnant or are breast-feeding, or planning a family. The severity of the psoriasis, associated comorbidities and specific anti-psoriasis treatment, along with other exposures, can have a deleterious effect on pregnancy outcomes. Psoriasis itself increases the risk of preterm and low birthweight babies, along with spontaneous and induced abortions, but no specific birth defects have been otherwise demonstrated. The baseline risk for a live born baby to have a major birth defect is 3%, and significant neuro-developmental problem is 5%. In Australia, pregnant women with psoriasis are more likely to be overweight or obese, depressed, or smoke in their first trimester, and are also less likely to take prenatal vitamins or supplements. Preconception counselling to improve maternal, pregnancy and baby health is therefore strongly encouraged. The topical and systemic therapies commonly used in psoriasis are each discussed separately, with regards to pregnancy exposure, breast-feeding and effects on male fertility and mutagenicity. The systemic therapies included are acitretin, adalimumab, apremilast, certolizumab, ciclosporin, etanercept, infliximab, ixekizumab, methotrexate, NBUVB, prednisone, PUVA, secukinumab and ustekinumab. The topical therapies include dithranol (anthralin), calcipotriol, coal tar, corticosteroids (weak, potent and super-potent), moisturisers, salicylic acid, tacrolimus, and tazarotene. As a general recommendation, effective drugs that have been widely used for years are preferable to newer alternatives with less foetal safety data. It is equally important to evaluate the risks of not treating, as severe untreated disease may negatively impact both mother and the foetus.

Managing IBD Therapies in Pregnancy

OPINION STATEMENT

Inflammatory bowel disease is frequently diagnosed before or during key childbearing years. One of the most important factors for a healthy pregnancy is having quiescent disease prior to conception and maintaining disease remission for the duration of the pregnancy. In order to achieve that, most women will need to continue their inflammatory bowel disease (IBD) treatment during pregnancy. One of the main concerns these women have is whether these medications will have adverse effects on their growing fetus. Aminosalicylates, antibiotics, and steroids are all relatively low risk for use during pregnancy and breastfeeding. Recent studies also support the safety of continuing immunomodulators and anti-tumor necrosis factor agents during pregnancy and with breastfeeding. There seems to be an increased risk for infection, however, with use of combination therapy including both a biologic agent and an immunomodulator. Less evidence is available on the use of anti-integrins in pregnancy; however, the current data suggest they may be safe as well. Conversations about a patient's desire for pregnancy should occur between the patient and provider on a regular basis prior to conception and particularly with any change in disease activity or change in the treatment regimen. This chapter will review the current evidence on the safety of IBD medications during pregnancy and lactation so that providers can more easily discuss the importance of medication adherence for disease remission with their patients who are contemplating conception.

Nausea and vomiting of pregnancy - What's new?

Nausea and vomiting of pregnancy (NVP) is one of the most common disorders of pregnancy. The symptoms occur predominantly during the first trimester, although in a subgroup of patients they can continue throughout the entire pregnancy and can affect the woman's quality of life. A small percentage of women develop a severe form of NVP called hyperemesis gravidarum (HG) that if left untreated may lead to significant maternal morbidity and adverse birth outcomes. Overall, the morbidity in pregnant women with NVP is significant, although it tends to be underestimated. The pathogenesis of NVP remains unclear, but there is consensus that the disorder is multifactorial and that various genetic, endocrine and infectious factors may be involved. The treatment of NVP can be challenging as the optimal targets for therapy are not known. Currently, the therapy used depends on the severity of the disorder and it is focused on improving the symptoms while minimizing risks to mother and fetus. Therapies range from dietary changes, pharmacologic treatment or hospitalization with intravenous fluid replacement and nutrition therapy. The aims of this review are 1) to provide an overview of NVP, 2) to present possible links between the most important factors associated with the pathogenesis of NVP and 3) to discuss the effectiveness and safety of the pharmacologic and non-pharmacologic options available to treat this disorder.

Maternal and neonatal outcomes of pregnancies in women with Addison's disease: a population-based cohort study on 7.7 million births

OBJECTIVE

To assess if pregnancies among women with Addison's disease (AD) are at higher risk of adverse maternal and neonatal outcomes.

DESIGN

Population-based retrospective cohort study.

SETTING/POPULATION

All births in the United States' Healthcare Cost and Utilization Project-Nationwide Inpatient Sample from 2003 to 2011.

METHODS

Baseline characteristics were compared between women with AD and those without, and prevalence over time was measured. Logistic regression was used to estimate the effect of AD on maternal and neonatal outcomes by calculating the crude and adjusted odds ratios (OR) and corresponding 95% confidence intervals (95% CI).

RESULTS

We calculated a prevalence of AD in pregnancy of 5.5/100 000, increasing from 5.6 to 9.6/100 000 (P = 0.0001) over the 9-year study period. Compared with women without AD, women with AD were more likely to deliver preterm (OR 1.50, 95% CI 1.16-1.95), deliver by caesarean section (OR 1.32, 95% CI 1.08-1.61), have impaired wound healing (OR 4.28, 95% CI 2.55-7.18), develop infections (OR 2.44, 95% CI 1.66-3.58) and develop thromboembolism (OR 5.21, 95% CI 2.15-12.63), require transfusions (OR 6.69, 95% CI 4.69-9.54), and have prolonged postpartum hospital admissions (OR 5.71, 95% CI 4.37-7.47). Maternal mortality was significantly higher than in the comparison group (OR 22.30, 95% CI 6.82-72.96). Congenital anomalies (OR 3.62, 95% CI 2.05-6.39) and small-for-gestational age infants (OR 1.78, 95% CI 1.15-2.75) were more likely in these pregnancies.

CONCLUSIONS

Addison's disease significantly increases the risk of severe adverse maternal and neonatal outcomes, so pregnant women with AD are best managed in tertiary-care centres.

TWEETABLE ABSTRACT

Pregnancies complicated by Addison's disease have an increased risk of adverse maternal and neonatal outcomes.

Environmental factors related to the occurrence of oral clefts in a Brazilian subpopulation

Background:

A cross-sectional study was conducted at the Craniofacial Rehabilitation Center in the General Hospital of the University of Cuiabá, Cuiabá city, Mato Grosso, Brazil.

Materials and Methods:

Poisson regression model was used to analyze the relationship between antenatal factors and the occurrence of oral clefts in 116 patients.

Results:

Oral clefts were more common in males (64.66%) and White race (46.02%). The mean age of the children was 21.91 months. The most common type of cleft was cleft lip and palate (CLP, 55.17%). Maternal and paternal smoking in the first trimester of pregnancy and parity were significantly associated with the occurrence of CLP. Parent's age, educational level, and occupation did not interfere in the occurrence of oral clefts. There was also no significant association between maternal illness, medication use, alcohol consumption, and maternal exposure to chemicals in the first trimester of pregnancy and the occurrence of clefts in this population.

Conclusion:

The analysis of the environmental factors present during the pregnancy of children with oral clefts revealed a significant association between parity (second onward), maternal smoking, and paternal smoking and the occurrence of CL and/or palate in this population.

Review article: acute severe ulcerative colitis - evidence-based consensus statements

BACKGROUND

Acute severe ulcerative colitis (ASUC) is a potentially life-threatening complication of ulcerative colitis.

AIM

To develop consensus statements based on a systematic review of the literature of the management of ASUC to improve patient outcome.

METHODS

Following a literature review, the Delphi method was used to develop the consensus statements. A steering committee, based in Australia, generated the statements of interest. Three rounds of anonymous voting were carried out to achieve the final results. Acceptance of statements was pre-determined by ≥80% votes in 'complete agreement' or 'agreement with minor reservation'.

RESULTS

Key recommendations include that patients with ASUC should be: hospitalised, undergo unprepared flexible sigmoidoscopy to assess severity and to exclude cytomegalovirus colitis, and be provided with venous thromboembolism prophylaxis and intravenous hydrocortisone 100 mg three or four times daily with close monitoring by a multidisciplinary team. Rescue therapy such as infliximab or ciclosporin should be started if insufficient response by day 3, and colectomy considered if no response to 7 days of rescue therapy or earlier if deterioration. With such an approach, it is expected that colectomy rate during admission will be below 30% and mortality less than 1% in specialist centres.

CONCLUSION

These evidenced-based consensus statements on acute severe ulcerative colitis, developed by a multidisciplinary group, provide up-to-date best practice recommendations that improve and harmonise management as well as provide auditable quality assessments.

Cluster Headache: Special Considerations for Treatment of Female Patients of Reproductive Age and Pediatric Patients

Cluster headache is a rare disorder that is more common in adult male patients. It has a unique phenotype of unilateral, severe, to very severe headaches lasting 15 to 180 min with ipsilateral autonomic symptoms. Time to correct diagnosis can be protracted. A number of treatment options exist for the standard cluster headache patient, but special considerations must be made for female patients of reproductive age and pediatric patients. The objective of this article is to explore the current literature pertaining to special considerations in cluster headache management, including treatment of pregnant or breastfeeding patients and pediatric patients.

Overcoming challenges of treating inflammatory bowel disease in pregnancy

Inflammatory bowel disease (IBD) is frequently diagnosed before or during the peak reproductive years. Overall management of inflammatory bowel disease is becoming more complex given the nuances involved with multiple mechanisms of action of the current treatment and need for therapeutic monitoring for safety and efficacy; another layer of complexity is added in the setting of a pregnancy. In this review, we have identified several key challenges that health care providers face when caring for patients with IBD during pregnancy. The goal of this review is to provide the most up-to-date evidence and provide our expert recommendations so that providers can more comfortably address patients' questions about pregnancy in IBD and the associated risks as well as optimize their care to ensure the best outcomes possible.
