The use of dupilumab in severe atopic dermatitis during pregnancy: a case report

Maternal influences on offspring food allergy

The prevalence of allergies has been globally escalating. While allergies could appear at any age, they often develop in early life. However, the significant knowledge gap in the field is the mechanisms by which allergies affect certain people but not others. Investigating early factors and events in neonatal life that have a lasting impact on determining the susceptibilities of children to develop allergies is a significant area of the investigation as it promotes the understanding of neonatal immune system that mediates tolerance versus allergies. This review focuses on the research over the recent 10 years regarding the potential maternal factors that influence offspring allergies with a view to food allergy, a potentially life-threatening cause of anaphylaxis. The role of breast milk, maternal diet, maternal antibodies, and microbiota that have been suggested as key maternal factors regulating offspring allergies are discussed here. We also suggest future research area to expand our knowledge of maternal-offspring interactions on the pathogenesis of food allergy.

Association between maternal dupilumab exposure and pregnancy outcomes in patients with moderate-to-severe atopic dermatitis: A nationwide retrospective cohort study

BACKGROUND

There is limited epidemiological evidence on outcomes associated with dupilumab exposure during pregnancy; monitoring pregnancy outcomes in large populations is required.

OBJECTIVE

To investigate the potential association between exposure to dupilumab in pregnant women with atopic dermatitis and any adverse pregnancy, neonatal, congenital and post-partum outcomes.

METHODS

We performed a multicentre retrospective cohort study across 19 Italian tertiary referral hospital. Childbearing women were eligible if aged 18-49 years and carried out the pregnancy between 1 October 2018 and 1 September 2022.

RESULTS

We retrospectively screened records of 5062 patients receiving dupilumab regardless of age and gender, identifying 951 female atopic dermatitis patients of childbearing age, 29 of whom had been exposed to the drug during pregnancy (3%). The median duration of dupilumab treatment prior to conception was 22.5 weeks (range: 3-118). The median time of exposure to the drug during pregnancy was 6 weeks (range: 2-24). All the documented pregnancies were unplanned, and the drug was discontinued in all cases once pregnancy status was reported. The comparison of the study cohort and the control group found no significant drug-associated risk for adverse pregnancy, congenital, neonatal or post-partum outcomes. The absence of a statistically significant effect of exposure on the event was confirmed by bivariate analysis and multivariate analysis adjusted for other confounding factors.

CONCLUSIONS

This cohort of pregnant patients exposed to dupilumab adds to the existing evidence concerning the safety of biologic agents in pregnancy. No safety issues were identified regarding the primary outcome assessed. In clinical practice, these data provide reassurance in case of dupilumab exposure during the first trimester. However, the continuous use of dupilumab throughout pregnancy warrants further research.

An international consensus on the use of asthma biologics in pregnancy

Uncontrolled asthma is associated with an increased risk of adverse perinatal outcomes. Asthma biologics reduce exacerbation frequency, are steroid sparing, and improve quality of life in people with severe asthma. However, evidence for the use and safety of asthma biologics during pregnancy is scarce, largely because pregnant women were excluded from clinical trials. To help to support clinical teams, we conducted an international modified Delphi study. 141 panellists from 32 countries who were involved in the care of people with severe asthma completed two rounds of online surveys covering key areas surrounding the use of asthma biologics in pregnancy. The results from this international Delphi study emphasise risk versus benefit discussions and shared clinical decision making, with consensus among panellists that asthma biologics can be used during conception and throughout pregnancy, initiated during pregnancy in line with prescribing criteria for non-pregnant people, and initiated or continued during breastfeeding. Collating data through international registries remains essential to inform clinical guidelines.

Atopic dermatitis in women: special considerations in the childbearing years

Background

Atopic dermatitis (AD) is one of the most common inflammatory dermatoses in adults. Women are disproportionately impacted by AD and report significant impacts on quality of life compared to men.

Objective

Given the absence of formal guidelines for the treatment of AD in women of childbearing age, we will review special considerations for treating women of childbearing age with AD to ensure consistent care and optimal outcomes for these patients.

Methods

PubMed and Google Scholar databases were searched for relevant articles from database inception through May of 2023.

Results

There are several treatments including topical therapies, systemic therapies, and phototherapy that are considered safe during preconception, pregnancy and breastfeeding. Given the negative consequences of uncontrolled AD for both the mother and the unborn baby, the risks and benefits of potential therapies should be reviewed with all women of childbearing age suffering from AD.

Limitations

The gold standard in recommending therapies is randomized controlled trials; however, pregnant and lactating women are often excluded from these trials.

Conclusion

Through shared decision-making between the dermatologist, obstetrician, and patient, the risks and benefits of any therapy should be thoroughly discussed and considered with all women of childbearing age, to optimize care and outcomes for this unique population.

Asthma in pregnancy: a review of recent literature

PURPOSE OF REVIEW

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

RECENT FINDINGS

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

SUMMARY

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

Targeted Systemic Therapies for Adults with Atopic Dermatitis: Selecting from Biologics and JAK Inhibitors

Therapeutic options for people with moderate or severe atopic dermatitis refractory to topical therapy have rapidly expanded in recent years. These new targeted immunomodulatory agents-biologics and Janus kinase (JAK) inhibitors-have each demonstrated high levels of efficacy and acceptable safety in mostly placebo-controlled clinical trials for atopic dermatitis, but there is no universally applicable algorithm to help choose between them for a given patient. Hence, patients and physicians should utilize shared decision making, discussing efficacy, safety, mode of delivery, monitoring, costs, speed of onset, and other factors to reach individualized treatment decisions. In this review, we try to aid shared decision making by summarizing the efficacy, safety, and monitoring of biologics and oral JAK inhibitors for adults with atopic dermatitis. Network meta-analyses suggest that higher doses of abrocitinib and upadacitinib are more effective than biologics. They also show that, among biologics, dupilumab is likely more effective than tralokinumab and lebrikizumab. Biologics are generally considered safer than JAK inhibitors, although concerns about JAK inhibitors are mainly extrapolated from older generation JAK inhibitors used in higher-risk populations. We also outline evidence and considerations for choosing and using systemic immunomodulatory treatments for special populations including pregnant individuals, those with human immunodeficiency virus (HIV), hepatitis B and C, end stage kidney disease, and older adults.

Systemic anti-inflammatory treatment of atopic dermatitis during conception, pregnancy and breastfeeding: Interdisciplinary expert consensus in Northern Europe

Treating atopic dermatitis (AD) in pregnant or breastfeeding women, and in women and men with AD aspiring to be parents is difficult and characterized by uncertainty, as evidence to inform decision-making on systemic anti-inflammatory treatment is limited. This project mapped consensus across dermatologists, obstetricians and patients in Northwestern Europe to build practical advice for managing AD with systemic anti-inflammatory treatment in men and women of reproductive age. Twenty-one individuals (sixteen dermatologists, two obstetricians and three patients) participated in a two-round Delphi process. Full consensus was reached on 32 statements, partial consensus on four statements and no consensus on four statements. Cyclosporine A was the first-choice long-term systemic AD treatment for women preconception, during pregnancy and when breastfeeding, with short-course prednisolone for flare management. No consensus was reached on second-choice systemics preconception or during pregnancy, although during breastfeeding dupilumab and azathioprine were deemed suitable. It may be appropriate to discuss continuing an existing systemic AD medication with a woman if it provides good disease control and its benefits in pregnancy outweigh its risks. Janus kinase (JAK) inhibitors, methotrexate and mycophenolate mofetil should be avoided by women during preconception, pregnancy and breastfeeding, with medication-specific washout periods advised. For men preconception: cyclosporine A, azathioprine, dupilumab and corticosteroids are appropriate; a 3-month washout prior to conception is desirable for methotrexate and mycophenolate mofetil; there was no consensus on JAK inhibitors. Patient and clinician education on appropriate (and inappropriate) AD treatments for use in pregnancy is vital. A shared-care framework for interdisciplinary management of AD patients is advocated and outlined. This consensus provides interdisciplinary clinical guidance to clinicians who care for patients with AD before, during and after pregnancy. While systemic AD medications are used uncommonly in this patient group, considerations in this article may help patients with severe refractory AD.

Asthma in pregnancy

Background: Asthma is a frequent and potentially life-threatening disease that complicates many pregnancies. There are extensive data with regard to the diagnosis and treatment of asthma during pregnancy. Medical providers require an up-to-date summary of the critical aspects of asthma management during pregnancy. Objective: This review aimed to summarize the available data from clinical trials, cohort studies, expert opinions, and guideline recommendations with regard to asthma in pregnancy. Methods: A search through PubMed was conducted by using keywords previously mentioned and MeSH (Medical Subject Headings) terminology. Clinical trials, observational studies, expert opinions, guidelines, and other reviews were included. The quality of the studies was assessed, and data were extracted and summarized. Results: Asthma worsens in ∼40% of pregnant women, which can be associated with maternal and fetal complications. Physiologic changes in the respiratory, cardiovascular, and immune systems during pregnancy play a critical role in the manifestations of asthma. The diagnosis and the treatment of asthma are similar to that of patients who are not pregnant. Nonetheless, concern for fetal malformations, preterm birth, and low birth weight must be considered when managing pregnant patients with asthma. Importantly, cornerstones of the pharmacotherapy of asthma seem to be safe during pregnancy. Conclusion: Asthma in pregnancy is associated with adverse outcomes. Roadblocks to management include associated comorbidities, medication nonadherence, atopy, lack of education, and smoking habits. These need to be acknowledged and addressed for successful asthma management during pregnancy.

Safety of Biologics for Atopic Diseases During Pregnancy

The high prevalence of atopic diseases in women of childbearing age reveals the need to determine the safety of biologics during pregnancy. This review summarizes the effects of 7 Food and Drug Administration-approved biologics (omalizumab, mepolizumab, reslizumab, benralizumab, dupilumab, tezepelumab, and tralokinumab) on maternal and fetal outcomes. For this purpose, we reviewed English-language publications to investigate whether the use of biologics for atopic diseases during pregnancy increased the risk of preterm delivery, stillbirth, low birth weight, or congenital malformations. Most publications found were case reports, case series, or observational studies reporting outcomes in a total of 313 pregnancies. No randomized controlled studies were identified. We found that biologics do not seem to influence maternal or fetal outcomes. Indeed, worsening of the underlying atopic disease during pregnancy appears to be more detrimental to the viability of the pregnancy. Given the small sample size and scarcity of studies, future research should include prospective studies with comparable control groups without exposure to biologics and multicenter registries for long-term follow-up.

Atopic Dermatitis with Multiple Comorbidities Treated with Dupilumab. A Case Report and Review of the Literature Regarding the Safety of Dupilumab

Dupilumab is the only available biological treatment for moderate-to-severe atopic dermatitis (AD). Even so, limited clinical data regarding its safety profile are available. Interactions with other drugs and the adverse effects of Dupilumab on patients with multiple comorbidities, such as chronic heart disease, diabetes, chronic kidney disease, etc., are not known yet. Moreover, there have been described cases of cutaneous lymphomas induced by Dupilumab. Therefore, the clinician that wants to start treatment for moderate-to-severe atopic dermatitis, which does not respond to conventional drugs, might be reluctant to choose biologic agents such as Dupilumab. In this paper, we reported a case of severe atopic dermatitis with multiple comorbidities in which the patient was successfully treated with Dupilumab despite numerous underlying conditions. We also conducted a review of the current literature on the safety profile of Dupilumab in special categories of patients with comorbidities, such as heart, kidney, and liver disease, oncologic conditions, and during pregnancy.

Dupilumab therapy in Atopic Dermatitis is safe during COVID-19 infection era: A systematic review and meta-analysis of 1611 patients

The aim of this meta‐analysis is to evaluate the safety of dupilumab use in the management of atopic dermatitis (AD) during the current pandemic regarding the risk and the hazards of COVID‐19 infection. Seven databases (Google Scholar, Web of Science, Scopus, Virtual Health Library, PubMed, System for Information on Gray Literature in Europe, and The New York Academy of Medicine) were searched for eligible studies from inception until November 24, 2021. The quality of evidence was rated using the National Institute of Health and the Joanna Briggs Institute Critical Appraisal tool. Meta‐analysis was performed when the outcome is presented ≥2 studies. A total of 12 papers including 1611 AD patients were included in the study. The prevalence of COVID‐19 in AD treated with dupilumab was 3.2% (95% confidence interval [CI]: 1.7–5.8). COVID‐19 symptoms were reported by five patients who were presented with one or more of the following symptoms (fatigue, loss of taste and smell, runny nose, conjunctivitis, gastrointestinal symptoms, fever, cough, and dyspnea). Only three cases of COVID‐19 were hospitalized with a prevalence of 4.5%, while no patients with COVID‐19 died. Dupilumab is safe regarding the risk and the hazards of COVID‐19 in AD patients. Thus, based on these results continuation of dupilumab in AD patients is recommended, since dupilumab seems to be safe and crucial for a better disease outcome.
