Treatment of atopic dermatitis in pregnancy

Maternal, Fetal, and Labour Outcomes of Dupilumab Use for Atopic Dermatitis During Pregnancy: A Systematic Review

Atopic dermatitis is a chronic complex inflammatory disease that significantly impacts maternal well-being and quality of life during pregnancy, warranting effective therapeutic interventions that prioritize maternal health and fetal safety. Dupilumab is approved for moderate-to-severe atopic dermatitis, but limited data exist regarding its safety during pregnancy. We conducted a systematic review to review and analyze maternal, fetal, and labour outcomes in patients receiving dupilumab for atopic dermatitis during pregnancy. Comprehensive searches were conducted using databases including OVID, Scopus, and Web of Science, covering studies published until May 2024. Our search yielded 285 studies, of which 13 met the eligibility criteria. These studies included 68 patients with 69 pregnancies, revealing 58 live births and 11 spontaneous abortions. Dupilumab therapy was administered continuously throughout pregnancy in 22.2% of cases, while 77.8% received intermittent treatment. Maternal atopic dermatitis outcomes showed significant improvement in disease severity. Most pregnancies (86.3%) progressed without complications. Labour-associated outcomes varied, with 82.4% of women undergoing vaginal deliveries. The majority of births occurred at full term (82.5%), with a mean gestational age of 38.4 weeks. Fetal outcomes demonstrated a normal birth weight in 92.3% of cases, with no reported congenital defects. Our review suggests that dupilumab use during pregnancy is associated with improvement of atopic dermatitis and low or minimal risk of major adverse outcomes in treated patients or their newborns. Prospective studies with long-term follow-up are warranted to confirm the safety of dupilumab in this population.

The Impact of Atopic Dermatitis on Sexual Function and Reproductive Desires in Women

Atopic dermatitis is a prevalent skin condition that affects up to 17% of adult population. It can lead to itching, pain, and other symptoms such as sleep disturbance, anxiety, and depression. Due to its high prevalence and limiting symptoms, atopic dermatitis often has a great impact on patients' quality of life but there is scarce information regarding how atopic dermatitis affects women's sexual health and reproductive desires. The purpose of this article was to assess the impact of atopic dermatitis on sexual function and reproductive wishes in women. A cross-sectional study was conducted from February to March 2022. A total of 102 women with atopic dermatitis were recruited through online questionnaires sent through the Spanish Atopic Dermatitis Association; 68.6% of the patients acknowledged impairment in sexual function, especially those with more severe disease and those with genital and gluteal involvement. In addition, 51% of the women considered that atopic dermatitis may have an influence on their gestational desire, particularly those with gluteal involvement. In conclusion, atopic dermatitis has a great impact on sexual function and reproductive desires in women.

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.

Investigations on incidence and relevant factors of allergies in 5725 urban pregnant women: a cohort study in China

BACKGROUND

Allergic diseases are highly prevalent in the women of childbearing age. As we know, the immune system could change when pregnancy, which may affect the course of allergic diseases. Meanwhile, they also can affect the course and outcome of pregnancy. The data on incidence of allergies during pregnancy is lacking and conducting clinical trials in pregnant women was limited, therefore, we observed a prebirth cohort to supplement the relevant data and strengthen concerned research conductions.

OBJECTIVE

We aim to obtain the incidence of allergies in urban pregnancy and explore the relevant factors of allergic diseases in urban pregnancy.

METHODS

We design a multicenter and prospective cohort in 20 institutions above municipal level which were eligible according to the study design from 14 provinces covering all-side of China. This cohort was conducted from 13+6 weeks of gestation to 12 months postpartum and in our study, we chose the prenatal part to analyze. The outcome was developing allergies during pregnancy, which were diagnosed by clinicians according to the uniform criterion from National Health Commission. All the data was collected by electronic questionnaires through tablet computers.

RESULTS

The incidence of allergic diseases in urban pregnant women was 21.0% (95%CI 20.0% ~ 22.0%). From social demography data, the history of allergies of pregnant women and their parents had statistical significance(p < 0.01); For exposure to living or working environment, house decoration for less than half a year, exposure to plush toys, disinfectants, insecticides, antihistamines, glucocorticoids, antipyretic analgesics, tocolytic agent and probiotics had statistical significance (all p < 0.05); For psychological status, self-rated depression and anxiety had statistical significance (p = 0.026;p = 0.006).

CONCLUSION

The incidence of allergic diseases in urban pregnant women was similar to the former study and kept a medium-high level. The history of allergies of pregnant women and their parents, house decoration time, exposure to plush toys, disinfectants, insecticides, antihistamines, glucocorticoids, antipyretic analgesics, tocolytic agents, probiotics, self-rated depression, and anxiety were relevant factors of allergic diseases during pregnancy.

Urticaria in Pregnancy and Lactation

Chronic urticaria (CU) is a mast cell-driven chronic inflammatory disease with a female predominance. Since CU affects mostly females in reproductive age, pregnancy is an important aspect to consider in the context of this disease. Sex hormones affect mast cell (MC) biology, and the hormonal changes that come with pregnancy can modulate the course of chronic inflammatory conditions, and they often do. Also, pregnancy-associated changes in the immune system, including local adaptation of innate and adaptive immune responses and skewing of adaptive immunity toward a Th2/Treg profile have been linked to changes in the course of inflammatory diseases. As of now, little is known about the effects of pregnancy on CU and the outcomes of pregnancy in CU patients. Also, there are no real-life studies to show the safety of urticaria medications during pregnancy. The recent PREG-CU study provided the first insights on this and showed that CU improves during pregnancy in half of the patients, whereas it worsens in one-third; and two of five CU patients experience flare-ups of their CU during pregnancy. The international EAACI/GA2LEN/EuroGuiDerm/APAAACI guideline for urticaria recommends adopting the same management strategy in pregnant and lactating CU patients; starting treatment with standard doses of second-generation (non-sedative) H1 antihistamines, to increase the dose up to 4-folds in case of no response, and to add omalizumab in antihistamine-refractory patients; but also emphasizes the lack of evidence-based information on the safety and efficacy of urticaria treatments during pregnancy. The PREG-CU study assessed treatments and their outcomes during pregnancy. Here, we review the reported effects of sex hormones and pregnancy-specific immunological changes on urticaria, we discuss the impact of pregnancy on urticaria, and we provide information and guidance on the management of urticaria during pregnancy and lactation.

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

BACKGROUND

Atopic dermatitis is a common chronic skin disease that can occur in pregnancy. Current treatments include topical and systemic glucocorticoids and cyclosporine. Presently, the only biologic approved for atopic dermatitis is dupilumab with limited data available regarding its safety profile in pregnancy.

CASE PRESENTATION

We report a case of severe atopic dermatitis treated safely with dupilumab with no adverse maternal or fetal outcomes and resolution of atopic dermatitis postpartum in the absence of maintenance dupilumab therapy.

CONCLUSION

Here we demonstrate the safe use of dupilumab in pregnancy. Further research is needed to elucidate the role of dupilumab in the management of atopic dermatitis during pregnancy.

When topical therapy of atopic dermatitis fails: a guide for the clinician

INTRODUCTION

While topical medications are the first line of treatment for mild-to-moderate atopic dermatitis, they are ineffective in individuals with diffuse disease and moderate-to-severe atopic itch. For these individuals, as well as those who do not respond to topical treatments, systemic medicines are typically essential and helpful.

AREAS COVERED

We conducted a review of the literature to identify established systemic therapies, novel biologic agents, and recent advances in the pathophysiology of atopic dermatitis. The review discusses these data, which show that the majority of atopic itch medications now in development target the type 2 immune axis and brain sensitization, two main etiologies of atopic itch. We emphasize the evidence, efficacy, and side effect profiles of currently available systemic medications for atopic itch, as well as future potential for tailored therapy.

EXPERT OPINION

We give our professional opinion on the current state of knowledge about atopic eczema pathogenesis and the innovative targets and therapies for atopic itch that include MRGPRX2, periostin, gabaergic medicines, and JAK/STAT inhibitors. Additionally, we discuss patient populations that stand to benefit the most from targeting these molecules or utilizing these drugs, as well as those who may face a disproportionate weight of adverse effects.

Atopic Dermatitis Treated Safely with Dupilumab during Pregnancy: A Case Report and Review of the Literature

Dupilumab is currently the only biologic treatment approved for moderate-to-severe atopic dermatitis. Though limited, available clinical data describing dupilumab use in pregnancy have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Systemic treatment in pregnant women with atopic dermatitis is currently restricted to corticosteroids, cyclosporine A, and azathioprine. Atopic dermatitis often has a deleterious course in pregnancy which can cause substantial distress and significantly impact on global health and quality of life. We report a case of severe atopic dermatitis treated safely with dupilumab during pregnancy with no adverse maternal or fetal outcomes observed. Our case highlights that dupilumab use in pregnancy has its place but should always be preceded by careful assessment of the risks and benefits. Clinicians are encouraged to enroll their patients in relevant pregnancy registry studies to monitor outcomes in women exposed to dupilumab during pregnancy and lactation.

The therapeutic versatility of antihistamines: A comprehensive review

Antihistamines are common and readily available medications for primary care patients and those seeking over-the-counter treatments. This article provides an overview of available antihistamines, their mechanisms of action, safety concerns in specific populations, and their therapeutic uses in several common conditions.

Changing perspectives in atopic dermatitis

Atopic dermatitis (AD) is a multifaceted disease that involves a complex interplay between the skin and the immune system. The course of the disease depends strongly on the genetic background of the patient and on yet poorly-defined environmental factors. Changes in lifestyle could be behind the dramatic rise in the prevalence of AD across continents; including hygienic conditions, food, social habits, skin microbiome or exposure to a number of allergens. Although AD typically develops in childhood and disappears after a few years, in a relatively large number of patients it continues into adulthood. Adult AD can also appear de novo but it is often underdiagnosed and its treatment can be challenging. New, highly effective drugs are being developed to manage moderate and severe forms of the disease in adults. In this review, we highlight the most recent developments in diagnostic tools, current insights into the mechanistic basis of this disease, and therapeutic innovations.

A safety review of the medications used to treat atopic dermatitis

INTRODUCTION

Atopic dermatitis (AD) is a common disease in children and adults which causes severe physical discomfort and psychosocial distress. Recently novel therapies for AD have been FDA approved for use which creates the need to review the safety surrounding current FDA approved AD medications.

AREAS COVERED

Published clinical studies involving topical and oral FDA approved medications for AD are included in this review. Authors used PubMed research database to search for clinical trials involving AD patients.

EXPERT OPINION

AD is a common disease which currently has limited FDA approved medications. Given the chronicity of this disease, medications are needed which control disease while minimizing side effects to allow for long term use. Newer approved medications show promise but safety data is limited given their relatively new utilization for AD.

Allergic diseases and asthma in pregnancy, a secondary publication

Every fifth pregnant woman is affected by allergies, especially rhinitis and asthma. Allergic symptoms existing before pregnancy may be either attenuated, or equally often promoted through pregnancy. Optimal allergy and asthma diagnosis and management during pregnancy is vital to ensure the welfare of mother and baby. For allergy diagnosis in pregnancy, preferentially anamnestic investigation as well as in vitro testing should be applied, whereas skin testing or provocation tests should be postponed until after birth. Pregnant women with confirmed allergy should avoid exposure to, or consumption of the offending allergen. Allergen immunotherapy should not be initiated during pregnancy. In patients on immunotherapy since before pregnancy, maintenance treatment may be continued, but the allergen dose should not be increased further. Applicable medications for asthma, rhinitis or skin symptoms in pregnancy are discussed and listed. In conclusion, i) allergies in pregnancy should preferentially be diagnosed in vitro; ii) AIT may be continued, but not started, and symptomatic medications must be carefully selected; iii) management of asthma and allergic diseases is important during pregnancy for welfare of mother and child.

Mast cell-mediated and associated disorders in pregnancy: a risky game with an uncertain outcome?

During pregnancy, the maternal organism is under the influence of tremendous endocrine as well as immunological changes as an adaptation to the implanted and developing fetus. In most cases, the maternal adaptations to pregnancy ensure both, the protection against harmful pathogens and the tolerance toward the growing semi-allogeneic fetus. However, under certain circumstances the unique hormonal milieu during pregnancy is causative of a shift into an unfavorable direction. Of particular importance are cellular disorders previous to pregnancy that involve cell types known for their susceptibility to hormones. One interesting cell type is the mast cell (MC), one of the key figures in allergic disorders. While physiological numbers of MCs were shown to positively influence pregnancy outcome, at least in mouse models, uncontrolled augmentations in quantity, and/or activation can lead to pregnancy complications. Women that have the desire of getting pregnant and been diagnosed with MC mediated disorders such as urticaria and mastocytosis or chronic inflammatory diseases in which MCs are involved, including atopic dermatitis, asthma, or psoriasis, may benefit from specialized medical assistance to ensure a positive pregnancy outcome. In the present review, we address the course of pregnancy in women affected by MC mediated or associated disorders.
