The relationship between maternal corticosteroid use and orofacial clefts-a meta-analysis

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.

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.

Maternal Exposure to Stress During Covid-19 and Non-Syndromic Orofacial Clefts: A Cohort Retrospective Study

OBJECTIVE

The coronavirus (COVID-19) pandemic presents an opportunity to study stress's effect on the development of non-syndromic orofacial clefts (NSOFCs). This study was aimed at assessing maternal stress exposure during the pregestational to first trimester pregnancy periods and the development of NSOFCs during a year of the COVID-19 pandemic.

DESIGN

Cohort study of infants with NSOFCs and controls matched based on recruitment site and age.

SETTING

Government hospitals in Saudi Arabia between November 2020 and November 2021.

MAIN OUTCOME MEASURES

Data collection included NSOFC clinical examination and maternal stress exposure assessment using the Modified Life Events Questionnaire, the Fear of COVID-19 Scale, and a focus on the lack of pregnancy planning and a threatened miscarriage.

RESULTS

Of the 557 infants recruited, 191 had NSOFCs. Logistic regression analysis with adjusted odds ratios (AORs) that removed the effects of confounders showed that any of the seven stressful life events (AOR:3.78, P < .001) and the family histories of relatives with NSOFCs (AOR:9.73, P < .001) increased the AOR for NSOFC development. In contrast, maternal folic acid (AOR:0.56, P.010), threatened miscarriage (AOR:0.17, P = .001), fear of COVID-19 (AOR:0.83, P = .038), and suspected COVID-19 infection (AOR:0.43, P = .008) decreased the AOR for NSOFC development.

CONCLUSION

Along with an established risk associated with family history of birth defects, stressful life events may be a risk factor for NSOFC development. Beyond folic acid's known benefit, it may be that higher maternal health concerns contribute to increased protective health behaviors during pregnancy. Ongoing research is needed to specify the maternal risk factors for NSOFC.

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.

COVID-19 related risk factors and their association with non-syndromic orofacial clefts in five Arab countries: a case-control study

BACKGROUND

The environmental etiology of non-syndromic orofacial clefts (NSOFCs) is still under research. The aim of this case-control study is to assess COVID-19 associated factors that may be related to the risk of NSOFC in five Arab countries. These factors include COVID-19 infection, COVID-19 symptoms, family member or friends infected with COVID-19, stress, smoking, socioeconomic status and fear of COVID-19.

METHODS

The study took place in governmental hospitals in five Arab countries from November 2020 to November 2021. Controls are matched in the month of delivery and site of recruitment. A clinical examination was carried out using LASHAL classification. Maternal exposure to medication, illnesses, supplementation, COVID-19 infection during their pregestation and 1st trimester periods were evaluated using a validated questionnaire. Maternal exposure to stress was assessed using the Life Events scale, fear of covid-19 scale, family member or friend affected with covid-19 infection, pregnancy planning and threatened abortion.

RESULTS

The study recruited 1135 infants (386 NSOFC and 749 controls). Living in urban areas, maternal exposure to medications 3-months pregestation, maternal exposure to any of the prenatal life events and maternal fear of COVID-19 significantly increased the risk of having a child with NSOFC. On the other hand, mothers exposed to supplementation 3-months pregestation, mothers suspected of having COVID-19 infection, family members or friends testing positive with COVID-19 significantly decreased the risk of having a child with NSOFC.

CONCLUSIONS

This study suggests that NSOFC may be associated with maternal exposure to lifetime stress and COVID-19 fear in particular, with no direct effect of the COVID-19 infection itself. This highlights the importance of providing psychological support for expecting mothers during stressful events that affect populations such as the COVID-19 pandemic, in addition to the usual antenatal care.

Maternal stress as a risk factor for non-syndromic orofacial clefts: Systematic review and meta-analysis

Background

Non-syndromic orofacial clefts (NSOFC) are among the most common congenital malformations. Several studies have investigated the association between stress and NSOFC; however, they have reported different and heterogeneous results. Therefore, this systematic review was conducted to investigate the association between maternal periconceptional stress and non-syndromic orofacial clefts in infants.The research question was "Is maternal periconceptional stress an etiological factor for non-syndromic orofacial clefts in infants"?

Methods

Search strategy, inclusion/exclusion criteria, and data extraction from studies reporting periconceptional maternal exposure to stress and NSOFC were implemented without language restrictions. The risks of bias in the identified studies was assessed, and this information was used in the sensitivity analyses to explain heterogeneity. A meta-analysis of the extracted data was performed.

Results

Twelve eligible studies were included. Forest plot for meta-analysis of the association between maternal periconceptional exposure to stress and NSOFC among studies with adjustment for potential confounders showed a statistically significant association with an increased risk of NSOFC (odds ratio [OR]:1.17; P = 0.03), which was apparent for both cleft lip with and without palate (OR:2.07; P = 0.007) and cleft palate (OR:1.72; P = 0.003). There was a substantial heterogeneity between studies, which improved when analyzing only studies that were adjusted for potential confounders.

Conclusion

Based on the currently available evidence, maternal exposure to periconceptional stress could be considered a risk factor for NSOFCs. Therefore, we strongly recommend research investigating the effect of stress caused by the coronavirus disease-2019 pandemic on the incidence of clefts.

Pregnancy and neuromyelitis optica spectrum disorders: 2022 recommendations from the French Multiple Sclerosis Society

BACKGROUND

In 2020, the French Multiple Sclerosis (MS) Society (SFSEP) decided to develop a national evidence-based consensus on pregnancy in MS. As neuromyelitis optica spectrum disorders (NMOSD) shares a series of commonalities with MS, but also some significant differences, specific recommendations had to be developed.

OBJECTIVES

To establish recommendations on pregnancy in women with NMOSD.

METHODS

The French Group for Recommendations in Multiple Sclerosis (France4MS) reviewed PubMed and universities databases (January 1975 through June 2021). The RAND/UCLA appropriateness method, which was developed to synthesise the scientific literature and expert opinions on health care topics, was used to reach a formal agreement. Fifty-six MS experts worked on the full-text review and initial wording of recommendations. A sub-group of nine NMOSD experts was dedicated to analysing available data on NMOSD. A group of 62 multidisciplinary healthcare specialists validated the final proposal of summarised evidence.

RESULTS

A strong agreement was reached for all 66 proposed recommendations. They cover diverse topics, such as pregnancy planning, follow-up during pregnancy and postpartum, delivery routes, loco-regional analgesia or anaesthesia, prevention of postpartum relapses, breastfeeding, vaccinations, reproductive assistance, management of relapses, and disease-modifying treatments.

CONCLUSION

Physicians and patients should be aware of the new and specific evidence-based recommendations of the French MS Society for pregnancy in women with NMOSD. They should help harmonise counselling and treatment practise, allowing for better individualised choices.

Pregnancy and multiple sclerosis: 2022 recommendations from the French multiple sclerosis society

OBJECTIVE

The objective of this study was to develop evidence-based recommendations on pregnancy management for persons with multiple sclerosis (MS).

BACKGROUND

MS typically affects young women in their childbearing years. Increasing evidence is available to inform questions raised by MS patients and health professionals about pregnancy issues.

METHODS

The French Group for Recommendations in Multiple Sclerosis (France4MS) reviewed PubMed and university databases (January 1975 through June 2021). The RAND/UCLA appropriateness method was developed to synthesise the scientific literature and expert opinions on healthcare topics; it was used to reach a formal agreement. Fifty-six MS experts worked on the full-text review and initial wording of recommendations. A group of 62 multidisciplinary healthcare specialists validated the final proposal of summarised evidence.

RESULTS

A strong agreement was reached for all 104 proposed recommendations. They cover diverse topics, such as pregnancy planning, follow-up during pregnancy and postpartum, delivery routes, locoregional analgesia or anaesthesia, prevention of postpartum relapses, breastfeeding, vaccinations, reproductive assistance, management of relapses and disease-modifying treatments.

CONCLUSION

The 2022 recommendations of the French MS society should be helpful to harmonise counselling and treatment practice for pregnancy in persons with MS, allowing for better and individualised choices.

Local Glucocorticoid Administration Impairs Embryonic Wound Healing

Understanding the complex processes of fetal wound healing and skin regeneration can help to improve fetal surgery. As part of the integumentary system, the skin protects the newborn organism against environmental factors and serves various functions. Glucocorticoids can enter the fetal circulatory system by either elevated maternal stress perception or through therapeutic administration and are known to affect adult skin composition and wound regeneration. In the present study, we aimed at investigating the effects of local glucocorticoid administration on the process of embryonic wound healing. We performed in-ovo bead implantation of dexamethasone beads into skin incisional wounds of avian embryos and observed the local effects of the glucocorticoid on the process of skin regeneration through histology, immunohistochemistry and in-situ hybridization, using vimentin, fibronectin, E-cadherin, Dermo-1 and phospho-Histone H3 as investigational markers. Local glucocorticoid administration decelerated the healing of the skin incisional wounds by impairing mesenchymal contraction and re-epithelialization resulting in morphological changes, such as increased epithelialization and disorganized matrix formation. The results contribute to a better understanding of scarless embryonic wound healing and how glucocorticoids might interfere with the underlying molecular processes, possibly indicating that glucocorticoid therapies in prenatal clinical practice should be carefully evaluated.

Prednisolone and enoxaparin (clexane) therapy ('the Bondi protocol') for repeated IVF failure

PROBLEM

What is the impact of an empirical immune therapy protocol of prednisolone and enoxaparin (clexane) (the 'Bondi protocol') on women with repeated in vitro fertilization (IVF) failure?

METHOD OF STUDY

This was a retrospective review of live birth outcomes conducted on all transfer cycles performed by a single clinician (GS) at IVFAustralia between February 2016 and April 2020. This study consisted of 1786 transfer cycles, including 460 cycles treated with the Bondi protocol and 1326 without. Women with repeated IVF failure were given the Bondi protocol based on blood NK cell activity. Primary outcome was live birth and statistical analysis was performed with GraphPad Prism software with significance for P-values < .05.

RESULTS

Overall 'Bondi' and 'normal' protocol cycles had similar rates of IVF/ICSI, fresh/frozen transfers and use of preimplantation genetic testing (PGT). Women given the Bondi protocol were older, had more previous cycles and had higher blood NK cell activity. There was no significant difference in live birth rates (Bondi 26%, normal 28%). Bondi protocol live birth rates per transfer cycle were as high as 40% in patients under 38 years old. The Bondi protocol was more effective as NK activity increased from 'normal' to 'borderline' to 'high'. For high NK cell activity levels, live birth rates were over four times higher for women on the Bondi protocol (28%) than those on normal protocols (6%, P = .0007).

CONCLUSION

This study describes a simple and relatively safe immune therapy protocol that may improve IVF success rates in women with evidence of immune dysfunction.

Assessing the Risk of Relapse Requiring Corticosteroids After In Vitro Fertilization in Women With Multiple Sclerosis

BACKGROUND AND OBJECTIVES

Several studies have shown an increased risk of relapse after in vitro fertilization (IVF) in women with multiple sclerosis (MS), especially when a gonadotrophin-releasing hormone (GnRH) agonist stimulation protocol was used. Our objective was to investigate the risk of relapse after IVF in women with MS, overall and according to stimulation protocol (GnRH agonists vs antagonists), using data from the French national health insurance database.

METHODS

This retrospective cohort study included all women with MS who have benefited from IVF between January 1, 2010, and December 31, 2015, in France. Three-month exposed periods after IVF were compared with unexposed periods before IVF, each woman being her own control. Four outcomes were considered: annualized relapse rate (ARR), proportion of IVF with relapse, difference in the number of relapses "after-before," and the delay from IVF to the first relapse. Relapses were identified by an algorithm based on MS-related hospital admissions and the use of corticosteroid therapy. Stimulation protocols and disease-modifying therapies (DMTs) were identified using drug claims. Zero-inflated Poisson regression models adjusted for age at IVF and the presence of DMT were used. A random effect on women was included because women may undergo multiple IVF procedures. Subgroup analyses by stimulation protocol and IVF outcome (pregnancy or failure) were conducted.

RESULTS

A total of 225 women accounting for 338 IVF procedures were included (the mean age at the first IVF 34.6 ± 4.5 years; 36% of women underwent at least 2 IVF procedures during the period). No increase in the risk of relapse after IVF was found overall (before vs after IVF: 0.20 vs 0.18 relapse per patient-year; 7.7% vs 7.1% of IVF with women having at least one relapse) and in subgroups. A lower ARR before and after IVF was observed among women who remained treated until IVF.

DISCUSSION

The maintenance of DMT until IVF seemed to be a determining factor in reducing the risk of relapse. Women with MS should be reassured because we did not show an increased risk of relapse requiring the use of corticosteroid therapy after IVF neither with GnRH agonists nor with GnRH antagonists.

Management of allergic diseases in pregnancy

Allergic diseases like asthma, allergic rhinitis, food allergy, hymenoptera allergy, or atopic dermatitis are highly prevalent in women of childbearing age and may affect up to 30% of this age group. This review focuses on the management of allergic diseases during pregnancy. Furthermore, we discuss the challenges of counseling women with allergic diseases in the reproductive age, including considerations relevant to the ongoing SARS-CoV-2 pandemic. To create the optimal milieu for the unborn child, a multitude of immunological changes occur during pregnancy which may favor type 2 responses and aggravate disease phenotypes. In co-occurrence with suboptimal preconception disease control, this elevated Th2 responses may aggravate allergic disease manifestations during pregnancy and pose a risk for mother and child. Due to limitations in conducting clinical trials in pregnant women, safety data on anti-allergic drugs during pregnancy are limited. The lack of information and concerns among pregnant patients demands counseling on the benefits of anti-allergic drugs and the potential and known risks. This includes information on the risk for mother and child of disease aggravation in the absence of treatment. By doing so, informed decisions and shared decision-making can take place.

Congenital Adrenal Hyperplasia-Current Insights in Pathophysiology, Diagnostics, and Management

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders affecting cortisol biosynthesis. Reduced activity of an enzyme required for cortisol production leads to chronic overstimulation of the adrenal cortex and accumulation of precursors proximal to the blocked enzymatic step. The most common form of CAH is caused by steroid 21-hydroxylase deficiency due to mutations in CYP21A2. Since the last publication summarizing CAH in Endocrine Reviews in 2000, there have been numerous new developments. These include more detailed understanding of steroidogenic pathways, refinements in neonatal screening, improved diagnostic measurements utilizing chromatography and mass spectrometry coupled with steroid profiling, and improved genotyping methods. Clinical trials of alternative medications and modes of delivery have been recently completed or are under way. Genetic and cell-based treatments are being explored. A large body of data concerning long-term outcomes in patients affected by CAH, including psychosexual well-being, has been enhanced by the establishment of disease registries. This review provides the reader with current insights in CAH with special attention to these new developments.

Environmental factors in non-syndromic orofacial clefts: A review based on meta-analyses results

Non-syndromic orofacial clefts (NSOFCs) are prevalent birth defects with a complex etiology where several interacting genetic and environmental factors have been observed. This narrative review describes maternal exposures that have been significantly associated with protective effects or risk factors. The statistically significant information reported here was found in meta-analysis studies, taking advantage of their precision in defining intervention effects and their management of heterogeneity between studies. In addition, I propose a hypothesis explaining the biological basis for the results of the meta-analyses. This review aims to improve the evidence available in parent counseling, to prevent the occurrence of orofacial clefts by suggesting lifestyle changes.

Commonly used immunosuppressive drugs for kidney diseases and pregnancy: focus on open questions

Pregnancy is still a challenge in women with autoimmune diseases or kidney transplantation. In this context, management of the immunosuppressive therapy is critical, but, in spite of more than 60 years of experience, many issues remain open, also because of the difficulty in disentangling, in complex patients, the effect of the disease and of the frequent multiple treatments. For this purpose, we have tried to synthesize the existing knowledge and the unresolved issues, to support counseling and promote patient empowerment.

Maternal exposure to hydroxychloroquine and birth defects

Background

Hydroxychloroquine is a treatment for rheumatic disease and considered safe during pregnancy. Interest in hydroxychloroquine has increased as it is being examined as a potential treatment and prophylaxis for coronavirus disease 2019. Data on the risks of specific birth defects associated with hydroxychloroquine use are sparse.

Methods

Using data from two case–control studies (National Birth Defects Prevention Study and Slone Epidemiology Center Birth Defects Study), we described women who reported hydroxychloroquine use in pregnancy and the presence of specific major birth defects in their offspring. Cases had at least one major birth defect and controls were live‐born healthy infants. Women self‐reported medication use information in the few months before pregnancy through delivery.

Results

In total, 0.06% (19/31,468) of case and 0.04% (5/11,614) of control mothers in National Birth Defects Prevention Study, and 0.04% (11/29,838) of case and 0.05% (7/12,868) of control mothers in Birth Defects Study reported hydroxychloroquine use. Hydroxychloroquine users had complicated medical histories and frequent medication use for a variety of conditions. The observed birth defects among women taking hydroxychloroquine were varied and included nine oral cleft cases; the elevated observed:expected ratios for specific oral cleft phenotypes and for oral clefts overall had 95% confidence intervals that included 1.0.

Conclusion

While teratogens typically produce a specific pattern of birth defects, the observed birth defects among the hydroxychloroquine‐exposed women did not present a clear pattern, suggesting no meaningful evidence for the risk of specific birth defects. The number of exposed cases is small; results should be interpreted cautiously.

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.

Asthma Medication Use and Risk of Birth Defects: National Birth Defects Prevention Study, 1997-2011

BACKGROUND

Evidence regarding associations between maternal asthma medication use and birth defects is mixed.

OBJECTIVE

Estimate associations between asthma medciation use and 52 birth defects using National Birth Defects Prevention Study data from 1997 to 2011.

METHODS

We compared self-reported maternal asthma medication use for 28,481 birth defect cases and 10,894 nonmalformed controls. We calculated adjusted odds ratios (95% CIs) to estimate the risk of birth defects associated with early pregnancy asthma medication use (the month before through the third month of pregnancy), controlling for maternal age, race/ethnicity, body mass index, smoking, folic acid-containing supplement use, and parity. We calculated risks by medication groupings: bronchodilators, anti-inflammatories, and both.

RESULTS

Overall, 1304 (5%) case and 449 (4%) control women reported early pregnancy asthma medication use. We observed an association between asthma medication use and longitudinal limb deficiency (1.81; 95% CI, 1.27-2.58). Early pregnancy bronchodilator-only use was associated with cleft palate (1.50; 95% CI, 1.11-2.02), cleft lip (1.58; 95% CI, 1.12-2.23), longitudinal limb deficiency (2.35; 95% CI, 1.55-3.54), and truncus arteriosus (2.48; 95% CI, 1.13-5.42). Although early pregnancy anti-inflammatory-only use was not associated with the birth defects studied, use of both medications was associated with biliary atresia (3.60; 95% CI, 1.55-8.35) and pulmonary atresia (2.50; 95% CI, 1.09-5.78).

CONCLUSIONS

Consistent with previous National Birth Defects Prevention Study analyses, asthma medication use was not associated with most birth defects examined, but we observed modest risks for bronchodilator use and several birth defects. Our findings support maintaining adequate asthma treatment during pregnancy, because early pregnancy asthma exacerbations have been associated with adverse birth outcomes, including birth defects.

In vivo High-Content Screening in Zebrafish for Developmental Nephrotoxicity of Approved Drugs

Despite widespread drug exposure, for example during gestation or in prematurely born children, organ-specific developmental toxicity of most drugs is poorly understood. Developmental and functional abnormalities are a major cause of kidney diseases during childhood; however, the potential causal relationship to exposure with nephrotoxic drugs during nephrogenesis is widely unknown. To identify developmental nephrotoxic drugs in a large scale, we established and performed an automated high-content screen to score for phenotypic renal alterations in the Tg(wt1b:EGFP) zebrafish line. During early nephrogenesis, embryos were exposed to a compound library of approved drugs. After treatment, embryos were aligned within microtiter plates using 3D-printed orientation tools enabling the robust acquisition of consistent dorsal views of pronephric kidneys by automated microscopy. To qualitatively and quantitatively score and visualize phenotypes, we developed software tools for the semi-automated analysis, processing and visualization of this large image-based dataset. Using this scoring scheme, we were able to categorize compounds based on their potential developmental nephrotoxic effects. About 10% of tested drugs induced pronephric phenotypes including glomerular and tubular malformations, or overall changes in kidney morphology. Major chemical compound groups identified to cause glomerular and tubular alterations included dihydropyridine derivatives, HMG CoA reductase inhibitors, fibrates, imidazole, benzimidazole and triazole derivatives, corticosteroids, glucocorticoids, acetic acid derivatives and propionic acid derivatives. In conclusion, the presented study demonstrates the large-scale screening of kidney-specific toxicity of approved drugs in a live vertebrate embryo. The associated technology and tool-sets can be easily adapted for other organ systems providing a unique platform for in vivo large-scale assessment of organ-specific developmental toxicity or other biomedical applications. Ultimately, the presented data and associated visualization and browsing tools provide a resource for potentially nephrotoxic drugs and for further investigations.

Pregnancy in Liver Transplantation

Pregnancy after liver transplantation (LT) is increasingly common and is a frequent scenario that transplant physicians, obstetricians, and midwives encounter. This review summarizes the key issues surrounding preconception, pregnancy-related outcomes, immunosuppression, and breastfeeding in female LT recipients. Prepregnancy counseling in these patients should include recommendations to delay conception for at least 1-2 years after LT and discussions about effective methods of contraception. Female LT recipients are generally recommended to continue immunosuppression during pregnancy to prevent allograft rejection; however, individual regimens may need to be altered. Although pregnancy outcomes are overall favorable, there is an increased risk of maternal and fetal complications. Pregnancy in this cohort remains high risk and should be managed vigilantly in a multidisciplinary setting. We aim to review the available evidence from national registries, population-based studies, and case series and to provide recommendations for attending clinicians.

Preconception counseling of females with inflammatory bowel disease

Inflammatory bowel diseases (IBD) are commonly diagnosed in women of childbearing age. As such, pregnancy is often encountered in this subset of patients. Management of pregnancy in IBD patients poses numerous challenges as ensuring the safety of the mother and the fetus is required. Disease remission prior to pregnancy is a key determinant of both the course of IBD throughout gestation and pregnancy outcome. Thus, adequate preconception care is of paramount importance in order to achieve optimal maternal and perinatal outcomes and maintain disease quiescence throughout gestation. In addition, preconception care has a major role in improving patient's knowledge, concerns and misbeliefs related to reproductive-health issues among IBD patients. In this review, we discuss the various aspects involved in the preconception care of IBD patients.

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.

Autoimmune bullous diseases during pregnancy: Solving common and uncommon issues

Autoimmune bullous diseases during pregnancy pose a therapeutic challenge for medical dermatologists. There are main concerns with regard to the regimen, dose, route of administration, and potential harm to the fetus. Many therapeutic options may be safe during pregnancy despite official classifications. Furthermore, there are always questions regarding management during the lactation period. Additionally, issues exist about male and female fertility and the time of discontinuation of certain medications before conception. In this article, we present an overview of the literature based on answers to these issues to solve common and uncommon management problems that arise about a spectrum of autoimmune bullous diseases before conception, as well as during pregnancy and the lactation period.

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.

Insights into the treatment of inflammatory bowel disease in pregnancy

Patients diagnosed with inflammatory bowel disease (IBD) are most commonly diagnosed in late adolescence or early adulthood, with half of patients being diagnosed before age 32, thus impacting peak years of reproduction and family planning. While controlled IBD has no negative effects on the ability to conceive, there is overall a trend towards voluntary childlessness due to patients' concerns for adverse fetal outcomes from underlying IBD and from adverse medication effects. Active disease at the time of conception is associated with worsening disease activity during pregnancy and carries a higher risk of poor fetal outcomes. It is therefore important to maintain remission during pregnancy, which is often achieved with pharmacologic therapy. The goal of this paper is to provide a comprehensive review of the current literature and safety data for pharmacologic treatment of IBD in pregnancy, in breastfeeding women, and in men planning to have children.

Women's Health: Contemporary Management of MS in Pregnancy and Post-Partum

Multiple sclerosis (MS) primarily affects women in childbearing age and is associated with an increased risk of adverse post-partum outcomes. Relapses and now fetal exposure to disease modifying treatments in the early phase of pregnancy and thereafter are of concern. Safe and effective contraception is required for women who wish to delay or avoid pregnancy while on disease-modifying treatments. Counseling and planning is essential to assess the risk of both fetal and maternal complications, particularly now in the era of highly efficient and riskier therapies. The purpose of this review is to provide a practical framework using the available data surrounding pregnancy in MS with the goal of optimizing outcomes during this phase in MS.

Practical Evidence-Based Recommendations for Patients with Multiple Sclerosis Who Want to Have Children

Multiple sclerosis (MS) management presently aims to reach a state of no (or minimal) evidence of disease activity. The development and commercialization of new drugs has led to a renewed interest in family planning, since patients with MS may face a future with reduced (or no) disease-related neurological disability. The advice of neurologists is often sought by patients who want to have children and need to know more about disease control at conception and during pregnancy and the puerperium. When MS is well controlled, the simple withdrawal of drugs for patients who intend to conceive is not an option. On the other hand, not all treatments presently recommended for MS are considered safe during conception, pregnancy and/or breastfeeding. The objective of the present study was to summarize the practical and evidence-based recommendations for family planning when our patients (women and men) have MS.Funding TEVA Pharmaceutical Brazil.

Understanding the participation of GREM1 polymorphisms in nonsyndromic cleft lip with or without cleft palate in the Brazilian population

BACKGROUND

GREM1, which encodes Gremlin 1, an antagonist of bone morphogenic proteins with effects on proliferation and apoptosis, has been considered a candidate gene for nonsyndromic cleft lip with or without cleft palate (NSCL±P). In this study, we investigated potential associations of single nucleotide polymorphisms (SNP) in GREM1 and NSCL±P risk in the Brazilian population. Additionally, SNP-SNP interactions of GREM1 with previously reported rs1880646 variant in NTN1 (netrin 1), a gene also responsible for apoptotic phenotypes were verified.

METHODS

Applying Taqman allelic discrimination assays, we evaluated the variants rs16969681, rs16969816, rs16969862, and rs1258763 in 325 case-parent trios and in 1,588 isolated samples in a case-control study. Allelic and genotypic analyses, as well as interaction tests assessing gene-environmental factor (GxE) and SNP-SNP interaction with rs1880646 variant in NTN1, were performed based on logistic regression analysis adjusted for the effects of gender and genomic ancestry proportions.

RESULTS

The risk alleles of all SNP were undertransmitted in NSCL±P trios, though the case-control analysis confirmed only the association with rs16969862 alleles (OR: 0.78, 95% CI: 0.63-0.96, p = .02). The GxE interaction analysis revealed a significant interaction between maternal environmental contact with agrotoxics and rs16969816 (OR: 0.25, 95% CI: 0.08-0.74, p = .01), and pairwise interaction test with NTN1 rs1880646 yielded significant p values in the 1,000 permutation test for rs16969681, rs16969816, and rs16969862.

CONCLUSION

The GREM1 is involved in the etiology of NSCL±P in the Brazilian population and reveal that the interaction between GREM1 and NTN1 may be related with the pathogenesis of this common craniofacial malformation.

Treatment of Autoimmune Bullous Disorders in Pregnancy

Autoimmune bullous diseases (AIBD), including pemphigus, bullous pemphigoid, epidermolysis bullosa acquisita, mucous membrane pemphigoid, and pemphigoid gestationis, pose significant therapeutic challenges, especially in pregnant and post-partum breastfeeding patients or those planning to conceive. Data on the safety and efficacy of therapeutic interventions during the perinatal period are lacking because randomized controlled trials are typically not performed in this setting. However, many of the treatments for AIBD are also used in other diseases, so data can be extrapolated from studies or case reports in these other patient populations. It appears that many of the treatments for AIBD can adversely affect the fetus or neonate, and alterations in immune status caused by pregnancy-associated hormonal changes can negatively impact disease control. This article summarizes and weighs the risks and benefits of the various agents used to treat AIBD during pregnancy. We also present the available information on lactation as well as effects on male fertility.
