Pregnancy outcomes in women with moderate-to-severe psoriasis

Psoriasis knowledge gaps and misconceptions in the Middle East and North Africa (MENA) regions: patients' survey-based study

BACKGROUND

Misconceptions among psoriatic patients often lead to a negative impact on disease outcomes.

OBJECTIVES

Our main target was knowledge assessment among a sample of psoriatic patients in the Middle East and North Africa (MENA) region where data are scarce.

METHODS

The present study is a cross-sectional descriptive survey. It consists of an online questionnaire comprising 19 questions designed to assess psoriasis knowledge and five demographic questions. The questionnaire link was posted on the official Facebook page of the Kasr Al Ainy Psoriasis Unit (KAPU).

RESULTS

The questionnaire was taken by 527 participants, but only 396 responses were complete and adequate for analysis. The mean psoriasis knowledge score was higher in females (P = 0.005) and participants with advanced education degrees (P < 0.001). Patients reporting regular follow-ups with dermatologists were more likely to acknowledge joint involvement (P = 0.044) but also incorrectly assume biologics are a final cure (P = 0.038). In addition, they were more likely to assume psoriasis affects pregnancy (P = 0.013). Patients with a family history of psoriasis showed a better mean knowledge score than those without (P = 0.01). Only 54.55% of participants reported knowledge of possible disease exacerbation by drugs. A minority (26.77%) of our patients responded that a diet change could not permanently cure psoriasis.

CONCLUSION

This study reports knowledge gaps in a cohort of Arabic-speaking psoriasis patients, especially regarding areas of extracutaneous involvement, the hereditary nature of the disease, and the effect of psoriasis on pregnancy and fertility. Most participants were unaware that biological therapy and a change in diet do not offer a permanent cure. Dermatologists in our region must reach out to their patients and correct the various misconceptions reported in this study.

Medication use patterns in pregnant women with psoriasis: a nationwide study in Taiwan

BACKGROUND

Psoriasis, an autoimmune skin condition, affects 2-4% of the global population, with significant prevalence among women of childbearing age. Pregnancy presents challenges in managing psoriasis because of hormonal changes and treatment safety concerns. Understanding treatment patterns in pregnant women is crucial, given limited real-world evidence.

OBJECTIVES

To explore the utilization patterns of medications among pregnant women diagnosed with psoriasis within real-world data, utilizing data sourced from a nationwide database in Taiwan.

METHODS

This nationwide study utilized Taiwan's National Health Insurance (NHI) database and birth certificate application records. It included registered pregnant women diagnosed with psoriasis from 2005 to 2014. Medication usage was tracked 3 years before conception to 3 years after delivery. Medications were categorized based on Anatomical Therapeutic Chemical codes, and statistical analyses were conducted using SAS software.

RESULTS

In total, 30 267 pregnant women with psoriasis were studied. In total, 11 651 (38.5%) mothers had received ≥ 1 prescription during follow-up (exposed group) and 61.5% (18 616) had never received medication (unexposed group). Demographics and comorbidities were similar between these two groups. Topical corticosteroids were the most prescribed treatment, followed by phototherapy, with systemic drugs and biologics less common. During the study period, 11 096 women with psoriasis had used topical corticosteroids, 3376 had used nonsteroidal topical agents, 218 had used systemic agents or biologics and 519 had received treatment with phototherapy. Medication usage declined during pregnancy, reaching its lowest in the third trimester but rebounded postpartum.

CONCLUSIONS

Psoriasis medications, systemic, biological or topical, were largely discontinued during pregnancy, sometimes up to 2 years before and extending postpartum. Research is needed to understand its impact on maternal and child health.

Impact of Psoriasis on Pregnancy Desire and Possible Consequences on Fertility

INTRODUCTION

Approximately half of patients affected by psoriasis are women, and the management of female patients of childbearing age is an under-investigated topic. Some studies have shown a significant decrease in births in psoriatic patients due to intimacy and pregnancy avoidance and to potential birth complications.

OBJECTIVES

We sought to evaluate data on reproductive health in a cohort of female patients, to compare them with similar data in the general population and to assess the impact of psoriasis, especially genital psoriasis, on pregnancy desire and the prevalence of psoriasis in the children of patients with psoriasis.

METHODS

This retrospective observational study involved adult female patients with a diagnosis of psoriasis made during or before childbearing age. The enrolled patients were asked questions concerning fertility and previous pregnancies in relation to their dermatologic disease.

RESULTS

Of 100 women enrolled, 73 reported a history of pregnancy, for a total of 170 pregnancies. The average number of pregnancies to term and the average number of children per woman (1.2 ± 1) were lower than the national average. The percentage of miscarriages was 18.2%, higher than the national average; in particular, women with psoriatic arthritis had a greater percentage of miscarriages (27.4%). During the pregnancies, psoriasis was mainly stable (36.1%) or improved (29.2%), even though most patients (91.5%) did not follow any treatment.

CONCLUSIONS

Psoriasis impacts pregnancy desire and course. The management of psoriasis in women of childbearing age is crucial to minimize its burden on this vulnerable population.

Pregnancy Outcomes in Patients Treated with Upadacitinib: Analysis of Data from Clinical Trials and Postmarketing Reports

BACKGROUND AND OBJECTIVE

Upadacitinib is indicated for diseases affecting persons of childbearing potential including rheumatoid arthritis, psoriatic arthritis, axial spondyloarthritis, atopic dermatitis, Crohn's disease, and ulcerative colitis; however, teratogenicity was observed in animal studies. Given the potential for human fetal risk, pregnancy avoidance measures were required during clinical trials. This analysis describes pregnancy outcomes in patients exposed to upadacitinib during pregnancy.

METHODS

Clinical trial and postmarketing cases of in utero exposure to upadacitinib were identified in AbbVie's safety database through 25 April, 2023. Analysis of clinical trial cases and postmarketing reports are presented separately; prospective and retrospectively reported pregnancy outcomes are integrated for each. Descriptive rates are presented to summarize outcomes.

RESULTS

There were 128 maternal upadacitinib-exposed pregnancies with known outcomes identified; 80 and 48 pregnancies were reported in clinical trials and the postmarketing setting, respectively. In clinical trials (mean in utero exposure of 5 weeks, 3 days), live births (54%), spontaneous abortions (24%), elective terminations (21%), and ectopic pregnancy (1%) were reported. There was one report of a congenital malformation: a 35-week infant with an atrial septal defect. In postmarketing cases, live births (46%), spontaneous abortions (38%), elective terminations (15%), and ectopic pregnancy (2%) were reported.

CONCLUSIONS

As the data are limited for in utero exposure to upadacitinib, definitive conclusions cannot be drawn regarding the effect of upadacitinib on pregnancy outcomes. Rates of adverse pregnancy outcomes with upadacitinib exposure were comparable to rates observed in the general population or patients with autoimmune inflammatory diseases. To date, no apparent evidence of teratogenicity exists in the analyses of human pregnancies exposed to upadacitinib during the first trimester.

Impact of maternal psoriasis on adverse maternal and neonatal outcomes: a systematic review and meta-analysis

BACKGROUND

There is a dearth of robust evidence regarding the correlation between psoriasis with maternal and neonatal outcomes, making it challenging to establish definitive recommendations for the management of these patients. This systematic review and meta-analysis aimed to review the evidence with regard to the impact of maternal psoriasis on maternal and neonatal outcomes.

METHODS

Following the PRISMA guideline, a systematic search of English articles using PubMed, Embase, Scopus, ScienceDirect, Web of Science, Google Scholar, and the Cochrane Library was conducted. The search was performed from inception to 22nd of May 2022.

RESULT

A significant association was observed between psoriasis and maternal outcomes, including cesarean delivery [OR = 1.25 (95% CI: 1.13-1.30, p-value = 0.001)], (pre)eclampsia [OR = 1.29 (95% CI: 1.15-1.44, p-value = 0.0001)], gestational diabetes [Odds Ratio (OR) = 1.23 (95% Confidence Intervals (CI): 1.15-1.30, p-value = 0.001)], gestational hypertension [OR = 1.31 (95% CI: 1.18-1.45, p-value = 0.001)] and preterm birth [OR = 1.22 (95% CI: 1.10-1.35, p-value = 0.001)]. Also, there was a significant association between psoriasis and neonatal outcomes, including small for gestational age [OR = 1.07 (95% CI: 1.02-1.11, p-value = 0.053)], low birth weight [OR = 1.19 (95% CI: 1.02-1.38, p-value = 0.001)] and stillbirth [OR = 1.27 (95% CI: 1.04-1.55, p-value = 0.023)].

CONCLUSION

Maternal psoriasis could negatively impact maternal and neonatal outcomes. Our results strengthen the importance of close monitoring of the mothers' psoriasis status before and during pregnancy.

The effect of paternal psoriasis on neonatal outcomes: a nationwide population-based study

Background

Psoriasis is a chronic autoimmune disease involving both environmental and genetic risk factors. Maternal psoriasis often results in poor pregnancies that influence both mothers and newborns. However, the influence of paternal psoriasis on the newborn remains unknown. The aim of this study was to investigate whether paternal psoriasis is associated with increased risk of adverse neonatal outcomes, within a nationwide population-based data setting.

Methods

Singleton pregnancies were identified in the Taiwan National Health Insurance database and National Birth Registry between 2004-2011 and classified into four study groups according to whether mothers and spouses had psoriasis (paternal(-)/maternal(-), paternal(+)/maternal(-), paternal(-)/maternal(+), and paternal(+)/maternal(+)). Data were analyzed retrospectively. Adjusted odds ratios (aOR) or hazard ratios (aHR) were calculated to evaluate the risk of neonatal outcomes between groups.

Results

A total of 1,498,892 singleton pregnancies were recruited. Newborns of fathers with psoriasis but not of mothers with psoriasis were associated with an aHR (95% CI) of 3.69 (1.65-8.26) for psoriasis, 1.13 (1.06-1.21) for atopic dermatitis and 1.05 (1.01-1.10) for allergic rhinitis. Newborns of mothers with psoriasis but not of fathers with psoriasis were associated with an aOR (95% CI) of 1.26 (1.12-1.43) for low birth weight (<2500 g) and 1.64 (1.10-2.43) for low Apgar scores, and an aHR of 5.70 (2.71-11.99) for psoriasis.

Conclusion

Newborns of fathers with psoriasis are associated with significantly higher risk of developing atopic dermatitis, allergic rhinitis and psoriasis. Caution is advised for adverse neonatal outcomes when either or both parents have psoriasis.

Therapy of PsO in Special Subsets of Patients

Psoriasis is a chronic, inflammatory skin disease that may occur at any age, with a bimodal peak of incidence around the age of 16-20 years of age (early onset) and 57-60 years (late-onset). It is estimated that roughly 70% of patients develop the disease before the age of 40, which coincides with the reproductive years. Moreover, psoriasis is a chronic disease, meaning that, with increased life-duration expectancy, the number of patients affected with psoriasis aged over 65 years is going to increase and represent a big therapeutic challenge. Actually, no specific drug recommendation is available, based only on the age of the patients, while therapeutic prescription should take into account that elderly patients have more comorbidities than younger patients, with polypharmacy and an increased risk of drug interactions. Women with psoriasis are more likely to report a worse influence of the disease on their quality of life, and they are more susceptible to the development of depression. Furthermore, pregnancy and lactation represent a major contraindication to several systemic agents, and only a few studies exist providing the safety of certain drugs during these periods of life of a woman, such as certolizumab pegol. In this paper, we discuss systemic therapeutic strategies, including conventional and biological therapies, in a special subset of patients affected with moderate-to-severe psoriasis focusing on elderly patients and on female patients in fertile age, pregnancy, and lactation.

Oversight and Management of Women with Psoriasis in Childbearing Age

Psoriasis is a complex disease with many associated comorbidities, all of which have a negative impact on a patient's personal, social, and sexual life. There are some unique considerations in the effects of this disease among women. The average age of diagnosis in women with psoriasis is 28 years, and this onset corresponds to the fertile life of women. There is conflicting information about the effects of psoriasis on female fertility. Some studies suggest that this condition's associated comorbidities, personal behaviors, and reduced ovarian reserve, especially due to chronic inflammation, affect women's fertility. Another possible reason women with psoriasis are less likely to become pregnant is that their sexual intercourse frequency decreases after the condition's onset. The available information on the effects of pregnancy on women with psoriasis is limited. According to current evidence, most women will experience an improvement in their skin condition. Studies show that patients with moderate-to-severe psoriasis are more prone to experience pregnancy complications. The management of pregnant and lactating women with psoriasis is also difficult, as the safety profile of commonly used drugs in patients with psoriasis is not entirely known.

Psoriasis and adverse pregnancy outcomes: A nationwide case-control study in 491,274 women in Denmark

Background

The chronic systemic inflammation associated with psoriasis supposedly creates an undesirable milieu for a pregnancy, resulting in an increased risk of adverse pregnancy outcomes (APOs).

Objective

To investigate the association between psoriasis and APOs as well as how the association differs according to psoriasis severity (mild and moderate-to-severe).

Methods

This nationwide register-based case-control study collected data from 1973 to 2017. Cases were APOs (spontaneous abortion, ectopic pregnancy [EP], intrauterine fetal death, and stillbirth). Singleton live births were controls. Adjusted logistic regression models were used for statistical analyses.

Results

In total, 42,041 (8.56%) APOs and 449,233 (91.44%) controls were included. EP was the only APO that was found to be statistically associated with psoriasis (odds ratio, 1.34; 95% CI, 1.06-1.68). Odds ratio for EP was the highest for women with moderate-to-severe psoriasis (odds ratio, 2.77; 95% CI, 1.13-6.76). The absolute risk of EP was 2.48% higher for women with moderate-to-severe psoriasis compared with women without psoriasis (3.98% vs 1.50%).

Limitations

No access to clinical data confirming psoriasis severity.

Conclusion

The present study found a significant association between EP and psoriasis (absolute risk of 3.98%). As EP is the leading cause of maternal morbidity and mortality in the first trimester of pregnancy, our findings call for particular care for women of reproductive age with psoriasis.

Oxidative stress induces meiotic defects of oocytes in a mouse psoriasis model

Psoriasis, an immune-mediated inflammatory disease, is associated with poor pregnancy outcomes. Emerging evidence indicates that these defects are likely attributed to compromised oocyte competence. Nevertheless, little is known about the underlying associated mechanisms between psoriasis and poor oocyte quality. In this study, we construct an imiquimod-induced chronic psoriasis-like mouse model to review the effects of psoriasis on oocyte quality. We discover that oocytes from psoriasis-like mice display spindle/chromosome disorganization, kinetochore-microtubule mis-attachment, and aneuploidy. Importantly, our results show that melatonin supplement in vitro and in vivo not only increases the rate of matured oocytes but also significantly attenuates oxidative stress and meiotic defects by restoring mitochondrial function in oocytes from psoriasis-like mice. Altogether, our data uncover the adverse effects of psoriasis symptoms on oocytes, and melatonin supplement ameliorates oxidative stress and meiotic defects of oocytes from psoriatic mice.

Therapy of psoriasis during pregnancy and breast-feeding

There have been multiple systemic drugs approved for the therapy of psoriasis vulgaris and psoriasis arthritis (PsA) in the last decade. However, treatment decisions are difficult to make in women planning a pregnancy and in pregnant and lactating women due to the paucity of data for such cases. The strongest evidence for psoriasis therapy during pregnancy exists for topical corticosteroids. Medically controlled use of UVB-therapy is also considered safe. The best evidence regarding systemic therapy during pregnancy and lactation is available for the group of TNF-alpha inhibitors, which is also reflected in the respective medical product information. This is especially important in cases of psoriatic arthritis. Among traditional systemic therapeutics, the largest clinical experience exists for ciclosporin, which, if medically necessary, may be continued during gestation. However, TNF-alpha inhibitors, especially the pegylated form, should be preferred in case of pregnancy. Furthermore, an elective pregnancy termination is not necessary due to systemic therapy of psoriasis with many further substances during the first pregnancy weeks. The current work provides a comprehensive review of the scientific literature on treatment of psoriasis during pregnancy and lactation. Based on the available scientific information, severity of psoriasis and patient's comorbidities, the best possible therapeutic approach can be found in consensus with the patient.

Maternal and neonatal outcomes of births to women with psoriasis: a population-based cohort of 13 million births

PURPOSE

Psoriasis is a common auto-immune disease affecting the skin and joints for which the current literature remains limited and contradictory in the context of pregnancy. The purpose of our study was to evaluate the association between psoriasis in pregnancy and maternal and newborn outcomes.

METHODS

A population based retrospective cohort study was conducted using the 1999-2015 United States' Healthcare Cost and Utilization Project Nationwide Inpatient Sample. ICD-9 codes were used to identify delivery admissions to women with or without psoriasis, as well as maternal and fetal outcomes. Adjusting for baseline characteristics, multivariate logistic regression models were performed to estimate the effects of psoriasis on maternal and newborn outcomes.

RESULTS

The cohort consisted of 3737 women with psoriasis, among a total of 13,792,544 pregnancy admissions in US hospitals between the years 1999 and 2015, for a period prevalence of 27.1 cases per 100,000 pregnant women. Psoriasis was associated with preeclampsia, OR 1.4 (95% CI 1.2-1.6), gestational diabetes, 1.27 (1.13-1.42), myocardial infarction, 13.4 (3.3-54.6), chorioamnionitis, 1.3 (1.0-1.6), delivery by cesarean section, 1.2 (1.1-1.3), anemia, 1.74 (1.18-2.57), and requiring blood transfusions, 1.4 (1.0-1.8). Their newborns were at higher risk of being born preterm, 1.2 (1.1-1.4), congenital anomalies, 1.7 (1.2-2.4), and intra-uterine growth restriction, 1.5 (1.2-1.7).

CONCLUSION

Women with psoriasis and their newborns appear more prone to adverse outcomes of pregnancy. It would be prudent for these women to be followed closely during pregnancy by their obstetrical caregiver and dermatologist. Further investigation is warranted regarding the management of psoriasis during pregnancy.

Papulosquamous Disorders and Pregnancy

Pregnancy can influence the course of a number of dermatologic disorders. Interestingly, these disorders can also influence pregnancy outcomes negatively, due to a variety of underlying pathogenic mechanisms. These outcomes may range from low fetal birth weight, preterm birth, and miscarriages to perineal lacerations complicating deliveries. Our review highlights the impact that papulosquamous disorders may have on pregnancy and their course throughout pregnancy. We chose papulosquamous disorders due to their relatively high prevalence worldwide compared to other dermatologic disorders. This review also sheds light on any gaps in the literature relevant to this topic that should be addressed. 

Psoriasis and its management in women of childbearing age: tools to increase awareness in dermatologists and patients

Psoriasis is a common, chronic inflammatory disease with a multifactorial pathogenesis. Mean age at presentation of psoriasis is 28 years in women, which is almost the height of fertility age. Since women of childbearing potential represent a significant proportion of psoriatic patients, the impact of psoriasis and its treatment on fertility, pregnancy, and breastfeeding should be highlighted for a proper management. Therefore, when approaching to a psoriatic woman of childbearing age, Healthcare Providers should be adequately informed and ready to provide the patients with answers to the most frequently asked questions. The Italian Society of Dermatology and Venereology (SIDeMaST) has fostered a Task Force named "Psoriasis in Women of Childbearing Age" which is composed by a group of Italian female dermatologists with a high expertise in psoriasis treatment. The aims of the Task Force are to increase awareness of the disease and its treatment in patients of childbearing age among both dermatologists and women affected by psoriasis and to encourage counselling on family planning. With the aim of providing a real support for the proper management of the delicate journey to motherhood, the Italian Task Force has published two different informative booklets addressed to patients and dermatologists which focus on the main issues regarding psoriasis in women of childbearing age.

Safety of anti-TNF agents in pregnancy

Inflammatory bowel disease, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and psoriasis are associated with adverse pregnancy outcomes. Active maternal disease during pregnancy is associated with additional negative outcomes. Anti-TNF agents are effective treatments for inflammatory bowel disease, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and psoriasis. These agents cross the placenta starting in the second trimester, with levels detected for several months after birth. This has led to safety concerns, with continued therapy during pregnancy for both the mother and the infant. This review covers retrospective and prospective data published from various cohorts of pregnant women exposed to anti-TNF agents during pregnancy. It highlights the safety of anti-TNF drugs in pregnancy, breast-feeding, and during the first year of life of the infant.

State-of-the-Art Review of Pregnancy-Related Psoriasis

Psoriasis is a chronic immunologic disease involving inflammation that can target internal organs, the skin, and joints. The peak incidence occurs between the age of 30 and 40 years, which overlaps with the typical reproductive period of women. Because of comorbidities that can accompany psoriasis, including metabolic syndrome, cardiovascular involvement, and major depressive disorders, the condition is a complex one. The role of hormones during pregnancy in the lesion dynamics of psoriasis is unclear, and it is important to resolve the implications of this pathology during pregnancy are. Furthermore, treating pregnant women who have psoriasis represents a challenge as most drugs generally prescribed for this pathology are contraindicated in pregnancy because of teratogenic effects. This review covers the state of the art in psoriasis associated with pregnancy. Careful pregnancy monitoring in moderate-to-severe psoriasis vulgaris is required given the high risk of related complications in pregnancy, including pregnancy-induced hypertensive disorders, low birth weight for gestational age, and gestational diabetes. Topical corticosteroids are safe during pregnancy but effective only for localised forms of psoriasis. Monoclonal antibodies targeting cytokines specifically upregulated in psoriasis, such as ustekinumab (IL-12/23 inhibitor), secukinumab (IL-17 inhibitor) can be effective for the severe form of psoriasis during pregnancy. A multidisciplinary team must choose optimal treatment, taking into account fetal and maternal risks and benefits.

Maternal and Neonatal Outcomes in Pregnant Women with Psoriasis and Psoriatic Arthritis: A Systematic Review and Meta-Analysis

OBJECTIVE

Psoriasis and psoriatic arthritis (PsA) are inflammatory diseases that affect women in their reproductive years. We aimed to investigate whether maternal psoriasis and PsA are associated with adverse pregnancy outcomes.

METHODS

We searched multiple electronic databases from inception to 3 August 2020, and reference lists of selected articles. Observational studies reporting at least one pregnancy outcomes in women with psoriasis or PsA with a comparator of general population or healthy subjects were included. Data were pooled by random-effects models and expressed as odds ratio (OR) and 95% confidence interval (CI).

RESULTS

Overall, 16 studies were included in the meta-analysis. The pooled analyses showed pregnant women with psoriatic diseases have significantly higher risk of adverse maternal outcomes compared with general population (caesarean delivery: 1.33 (1.17-1.52); preterm birth: 1.32 (1.15-1.52); (pre)eclampsia: 1.28 (1.14-1.43); gestational diabetes: 1.19 (1.10-1.30); gestational hypertension: 1.30 (1.18-1.44). However, no statistically increased risks of fetal complications were observed in women with psoriatic diseases (small for gestational age: 1.02 (0.93-1.11); low birth weight: 1.15 (0.93-1.42); congenital malformations: 1.03 (0.93-1.14); Apgar score <7: 1.07 (0.81-1.39); neonatal mortality: 1.13 (0.90-1.43); stillbirth: 1.19 (0.95-1.50)). Subgroup analysis found similar results in women with either psoriasis or PsA regarding maternal outcomes and the magnitude of risk estimates seems to be greater in PsA though without statistical difference.

CONCLUSIONS

Pregnant women with psoriasis and PsA have excess risk of adverse maternal events, but not adverse neonatal events. Close monitoring of the mothers' clinical status before and during pregnancy is decidedly required in daily practice.

Management of Psoriasis During Preconception, Pregnancy, Postpartum, and Breastfeeding: A Consensus Statement

OBJECTIVE

To develop evidence- and experience-based recommendations for the management of psoriasis during preconception, pregnancy, postpartum, and breastfeeding.

METHODS

The nominal group technique and the Delphi method were used. Fifteen experts (12 dermatologists, 2 of whom were appointed coordinators; 1 rheumatologist; and 2 gynecologists) were selected to form an expert panel. Following a systematic review of the literature on fertility, pregnancy, postpartum, and breastfeeding in women with psoriasis, the coordinators drew up a series of preliminary recommendations for discussion by the panel at a nominal group meeting. The experts defined the scope, sections, and intended users of the statement and prepared a final list of recommendations. Consensus was obtained using a Delphi process in which an additional 51 dermatologists rated their level of agreement with each recommendation on a scale of 1 (total disagreement) to 10 (total agreement). Consensus was defined by a score of 7 or higher assigned by at least 70% of participants. Level of evidence and strength of recommendation were reported using the Oxford Center for Evidence-Based Medicine categories. The final statement was approved by the expert panel.

RESULTS

The resulting consensus statement includes 23 recommendations on preconception (fertility and contraception), pregnancy (planning, pharmacological management, and follow-up), and breastfeeding (management and follow-up). Consensus was achieved for all recommendations generated except one.

CONCLUSIONS

These recommendations for the better management of psoriasis in women of childbearing age could improve outcomes and prognosis.

Management of Plaque Psoriasis With Biologic Therapies in Women of Child-Bearing Potential Consensus Paper

BACKGROUND

Plaque psoriasis (PsO) is a chronic inflammatory disease that often presents at peak reproductive age in women of child-bearing potential (WOCBP). With the emergence of biologic therapies to treat PsO, guidance on disease management in WOCBP is needed to inform treatment decisions before, during, and after pregnancy.

OBJECTIVES

To develop a practical, up-to-date consensus document, based on available evidence and expert opinion where evidence was lacking, in order to guide both Canadian and international clinicians treating PsO in WOCBP.

METHODS

A panel of 9 Canadian dermatologists with extensive clinical experience managing PsO reviewed the relevant literature from the past 25 years in 3 key domains: overview of PsO in WOCBP and clinical considerations, treatment considerations, and postpartum considerations. The structured literature search focused on WOCBP treated with TNF-alpha inhibitors (adalimumab, certolizumab, etanercept, golimumab, infliximab), IL-23 inhibitors (guselkumab, risankizumab, tildrakizumab), IL-12/23 inhibitors (ustekinumab), and IL-17 inhibitors (brodalumab, ixekizumab, secukinumab). This literature review, along with clinical expertise and opinion, was used to develop concise and clinically relevant consensus statements to guide practical management of PsO in WOCBP. Experts voted on the statements using a modified Delphi process and prespecified agreement cut-off of 75%.

RESULTS AND IMPLICATIONS

After review, discussion, and voting on 19 draft consensus statements at an in-person meeting and remotely, 12 consensus statements were approved by the expert panel. The statements presented here will guide healthcare providers in practical disease management using biologic therapies for the treatment of PsO in WOCBP.

[Psoriasis and pregnancy : Clinical algorithm and monitoring of systemic therapy]

The recently expanded approval of some TNF‑α blockers for the treatment of moderate to severe psoriasis in pregnancy has facilitated therapy of this group of patients with approved drugs. To date, there are no evidence-based structured therapy recommendations for these psoriasis patients with the result that the uncertainties of the treating physicians usually lead to individual decisions. On the basis of our clinical experience and the currently valid approval for systemic therapeutics, we have developed a therapy algorithm that enables an interdisciplinary, structured approach to counseling and supporting pregnant women with psoriasis, which makes decision-making for colleagues in other disciplines, in particular gynecology, transparent.

Moderate-to-severe psoriasis and pregnancy: impact on fertility, pregnancy outcome and treatment perspectives

Psoriasis affects 2-4% of the world's population, with no difference between men and women and 70% of patients experiencing disease onset before the age of 40, which coincides with the reproductive years. Few data are available from literature on impact of psoriasis on fertility, course and outcome of pregnancy and risk associated with treatments. Recent studies on other immune-mediated inflammatory diseases, among which psoriasis is also included, indicate that rheumatoid arthritis and inflammatory bowel diseases can impact female fertility and pregnancy outcomes especially during active disease episodes. In psoriasis hormonal and metabolic comorbidities, unhealthy lifestyles and systemic inflammation could also influence the ability to conceive, pregnancy course and birth outcomes. In this article we review current knowledge on reproductive function, course and outcome of pregnancy in women affected by moderate-to-severe psoriasis. Systemic treatments are also considered with a special focus on TNF-alpha blocking agents and implication of molecular structure on placental transportation and fetal exposure.

[Psoriasis therapy in pregnancy : Consultation of pregnant patients]

Systemic therapy of pregnant patients with psoriasis requires special attention and has to be adapted to disease activity throughout the pregnancy. With the approval of the first tumor necrosis factor alpha inhibitors for the treatment of these patients, a new range of options has to be discussed with the women. If the inflammatory presentation of the psoriasis demands systemic therapy, the decision for treatment should be made as early as possible, preferably before the onset of pregnancy.

A Population-level Analysis of the Differing Effects of Rheumatoid Arthritis and Spondyloarthritis on Peripartum Outcomes

OBJECTIVE

The effects of rheumatoid arthritis (RA) and spondyloarthritis (SpA) on maternal and neonatal outcomes at a population level have not previously been well compared.

METHODS

A contemporary pregnancy cohort of 312,081 women and corresponding birth events was assembled for the province of Alberta from the random selection of 1 live birth event per woman. We identified 3 groups: (1) no inflammatory arthritis (no IA, n = 308,989), (2) RA (n = 631), and (3) SpA (n = 2461). We compared maternal and neonatal outcomes, comorbid conditions, and medication use among the 3 groups. Multivariable logistic regression models evaluated the independent association between RA and SpA, relative to no IA, and the outcomes of small for gestation age (SGA) and hypertensive disorders during pregnancy.

RESULTS

Pregnant women with RA were significantly more likely to have preterm delivery (13.5%), cesarean delivery (33.9%), hypertensive disorders in pregnancy (10.5%), and SGA babies (15.6%), compared to pregnant women with either SpA or no IA. Nonsteroidal antiinflammatory drugs and corticosteroid use were significantly higher in pregnant women with RA compared to the other groups. Women with RA were significantly more likely to have an SGA baby (OR 1.51, 95% CI 1.21-1.88; p < 0.01), and hypertensive disorder in pregnancy (OR 1.51, 95% CI 1.16-1.97; p < 0.01), compared to women with no IA, while no difference was found between women with SpA and those with no IA.

CONCLUSION

Women with RA have a higher risk of worse maternal and neonatal outcomes, whereas the risk of these events is similar between women with and without SpA.

Clinical considerations for the management of psoriasis in women

The burden of psoriasis is particularly high for women, who report lower levels of happiness (women: 18.5%; men: 11.3% lower vs. general population) and are more likely to experience stress (women: > 60%; men: 42%), loneliness (women: 25-28%; men: 19-24%), stigmatization (Feelings of Stigmatization Questionnaire score; women: 93.2; men: 78.0), and reduced sexual activity (women: 33%; men: 19%) compared with men. The onset of psoriasis is bimodal, with one incidence peak (15-30 years) that coincides with the prime reproductive age for women, which poses specific challenges for their treatment. However, well-established guidelines for the treatment of women of childbearing age are lacking. Many women experience stabilization (21%) or improvement (55%) of their skin during pregnancy, but up to a quarter can experience disease worsening, and postpartum flares are common (> 50%). Therefore, balancing the risk of treatment with the risk of uncontrolled disease is important. Because half of pregnancies are unplanned, the implications of therapeutic options must be considered for all women with psoriasis who are sexually active, irrespective of intentions to start a family. Timely initiation of these discussions by health care professionals is paramount to prevent unintentional toxicity to the developing fetus. For example, acitretin, methotrexate, and oral psoralen/ultraviolet A are all contraindicated in pregnancy. Reassuringly, safety data for other psoriasis treatments during pregnancy are increasingly available, particularly for anti-tumor necrosis factor therapies. Despite encouraging data from pregnancy exposure registries and clinical studies now being included in anti-tumor necrosis factor drug labels, comfort with prescribing these therapies to pregnant women remains low (U.S. dermatologists: 21%; EU-5 dermatologists: 10%). In this article, we review issues specific to treating women of childbearing age with psoriasis and highlight the need for treatment guidelines to ensure consistent care and optimal outcomes for these patients.

The Effect of Pregnancy on Disease Activity in Patients with Psoriatic Arthritis

OBJECTIVE

To evaluate the effect of pregnancy on disease activity in psoriatic arthritis (PsA).

METHODS

This is a retrospective case series. Review of the medical files of all female patients followed at the PsA clinic of 2 medical centers identified those with at least 1 pregnancy during followup and 1 visit during or soon after pregnancy.

RESULTS

Twenty-five women with PsA (out of 107 women of reproductive age followed up in our PsA clinics) and 35 pregnancies were enrolled. Thirty-three pregnancies resulted in live healthy babies. In the whole group, there was no significant change in disease activity throughout pregnancy, while in 16 (48%) of pregnancies, patients worsened during the first postpartum year. In 15 out of 21 pregnancies, in which the women had been treated before conception with biologics, treatment was discontinued close to pregnancy or during the first trimester. Five of those 15 patients had been classified as having mild to severe PsA activity prior to pregnancy. That number increased to 8, 9, and 14 during the first and second trimesters and postpartum period, respectively. There was no significant change in degree of disease activity in 6 patients whose biologics were continued beyond the first trimester. Improvement in disease activity was observed during pregnancy among the nonbiologics-treated patients. Corticosteroids were initiated or the dosage was increased during 6 pregnancies, all involving patients whose biologics were stopped before pregnancy.

CONCLUSION

Continuation of biologics therapy was associated with a low level of disease activity and a low probability of flare during pregnancy. Stopping treatment with biologics before pregnancy is associated with flare during pregnancy and the postpartum period.

Pregnancy After Tubal Sterilization in a Woman Treated with Biologics for Severe Psoriasis

Little is known about whether immunosuppressed patients mount the immunological response necessary to ensure tubal occlusion. Theoretical concern for non-occlusion has limited the use of hysteroscopic sterilization in patients on immunosuppressive therapies. The effects of tumor necrosis factor-alpha (TNF-α) blockers and interleukin (IL)-17 inhibitors on contraception and pregnancy for patients with psoriasis are poorly documented. We report a case of pregnancy that ended in miscarriage in a patient treated first with TNF-α and then with IL-17 inhibitors for severe psoriasis after tubal sterilization with micro-inserts. Our observation suggests that the efficacy of tubal sterilization by micro-inserts may be impaired by these two biologics and that the risk of miscarriage may be increased in women with psoriasis treated with secukinumab.

Pregnancy Outcomes in the Tofacitinib Safety Databases for Rheumatoid Arthritis and Psoriasis

INTRODUCTION

Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA), and is being investigated for the treatment of psoriasis. Both conditions can present in women of child-bearing potential, but pregnancy was an exclusion and discontinuation criterion in tofacitinib randomized controlled trials (RCTs) because of the unknown effects of tofacitinib on mother and child. Tofacitinib is a small molecule that has the potential to cross the placenta.

OBJECTIVE

The objective was to report outcomes of pregnancy cases identified through April 2014 from tofacitinib RA/psoriasis RCTs, RA post-approval non-interventional studies, and spontaneous adverse-event reporting.

METHODS

Pregnancy outcomes were categorized as follows: healthy newborn, medical termination, fetal death, congenital malformation, spontaneous abortion, or pending/lost to follow-up.

RESULTS

Out of 9815 patients, 1821 female patients of child-bearing age were enrolled in the RA/psoriasis RCTs; 47 women became pregnant, including 33 who received tofacitinib monotherapy, 13 who received combination therapy with methotrexate (RA patients only), and one patient whose therapy was still blinded. No fetal deaths were reported. One congenital pulmonary valve stenosis (monotherapy, n = 1), seven spontaneous abortions (monotherapy, n = 4; combination therapy, n = 3), and eight medical terminations (monotherapy, n = 4; combination therapy, n = 3; blinded therapy, n = 1) were identified. Remaining cases reported healthy newborns (n = 25) or were pending/lost to follow-up (n = 6). Forty-four cases of paternal exposure to tofacitinib were reported (monotherapy, n = 43; combination therapy, n = 1), including five spontaneous abortions (monotherapy, n = 4; combination therapy, n = 1), 23 healthy newborns, and 16 pending/lost to follow-up.

CONCLUSIONS

The pregnancy outcomes reported in this small number of RA/psoriasis patients appear similar to those observed in the general population and in patients treated with biologic therapies for inflammatory diseases. However, definitive conclusions cannot be drawn, and pregnancy outcomes in patients receiving tofacitinib will continue to be monitored.

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.

Psoriasis and adverse pregnancy outcomes: a systematic review of observational studies

Psoriasis is a chronic inflammatory disorder with significant physical and psychological sequelae. The majority of individuals experience disease onset in early adult life - for women this often occurs during their reproductive years. While some autoimmune diseases have been shown to affect pregnancy outcomes adversely, such a relationship has not been well studied in psoriasis. We searched PubMed, Embase and the Cochrane database for published articles examining psoriasis and adverse pregnancy outcomes, and included observational studies and clinical trials evaluating direct measures of maternal and fetal morbidity and mortality. Four of the nine included articles reported a statistically significant increase in the risk of at least one outcome, including spontaneous abortion, caesarean delivery, low birth weight, macrosomia, large-for-gestational age, and a composite outcome consisting of both prematurity and low birth weight. However, these associations were not always consistent across studies. Overall, there was no clear evidence of increased adverse outcomes in pregnant women with psoriasis.

The role of hormones in the pathogenesis of psoriasis vulgaris

Psoriasis vulgaris is a chronic, common skin disease, which affects the patient’s quality of life to the highest degree. Several exogenous factors and endogenous hormonal changes may act as triggers for psoriasis.

The skin possesses a true endocrine system, which is very important in multiple systemic diseases. A number of conditions are associated with psoriasis, and its severity can also be influenced by hormones. Even though the sex hormones and prolactin have a major role in psoriasis pathogenicity, there are a lot of other hormones which can influence the psoriasis clinical manifestations: glucocorticoids, epinephrine, thyroid hormones, and insulin.

Treating Psoriasis During Pregnancy: Safety and Efficacy of Treatments

Psoriasis is a chronic inflammatory disease with a well-documented negative effect on the quality of life of affected patients. Psoriasis often occurs in the reproductive years, during which the issue of pregnancy needs to be addressed. The course of psoriasis during pregnancy is unpredictable, and many patients face the challenge of needing treatment during pregnancy. In this review we provide an overview of the key considerations for managing psoriasis in pregnant women, covering the potential effects of active psoriasis and co-morbid conditions on the health of the mother and fetus, as well as the effects of psoriasis treatment options on the developing fetus. Although there are no robust data on the safety of systemic treatment of pregnant women, increasing evidence regarding the safety of cyclosporine (ciclosporin) treatment as well as anti-tumor necrosis factor-α is available and should be considered in pregnant women with moderate to severe psoriasis unresponsive to local corticosteroids and UVB light treatment.

Psoriasis in pregnancy: challenges and solutions

The available information about the effects of pregnancy on psoriasis and those of psoriasis on pregnancy is almost limited, despite the high frequency of the disease in the general population, as well as in women in reproductive years. Considering the existing evidence, pregnancy does not tend to have a negative influence on psoriasis, as in most women who experience a change in the severity and course of their psoriasis during pregnancy, the change is more likely to be reported as an improvement. This assumption can be applied more convincingly to plaque-type psoriasis, while an exception may be represented by generalized pustular psoriasis, which has been somehow linked to impetigo herpetiformis. Conflicting findings emerged from the few available studies that explored the effect of psoriasis on pregnancy outcomes. Recent studies found an association between moderate-to-severe psoriasis and some pregnancy complications, including pregnancy-induced hypertensive diseases, and have emphasized a trend toward a newborn with low birth weight in patients with psoriasis, especially in those suffering from severe forms. The safety profile during pregnancy is not completely known for many drugs used to treat psoriasis. Moisturizers and low- to moderate-potency topical steroids or ultraviolet B phototherapy represent the first-line therapy for pregnant patients. Many dermatologists may, however, recommend discontinuing all drugs during pregnancy, in consideration of medico-legal issues, and also taking into account that common forms of psoriasis do not compromise the maternal and fetal health. Anyway, for those women whose psoriasis improves during pregnancy, the interruption of any therapy for psoriasis can be a reasonable strategy. The objective of this paper was to review the most relevant literature data on psoriasis in pregnancy, trying to give concurrently practical information about clinical and prognostic aspects, as well as counseling and management.

Pregnancy during Ustekinumab Treatment for Severe Psoriasis

We report the case of a 25-year-old patient who became pregnant during ustekinumab therapy. Treatment was suspended immediately after pregnancy had been confirmed. The patient had an uneventful pregnancy and her child is currently 14 months old, with adequate development to her age. Four reports of pregnancy during ustekinumab treatment have been reported and one resulted in miscarriage.

Associations of maternal atopic diseases with adverse pregnancy outcomes: a national cohort study

BACKGROUND

Maternal asthma has been associated with adverse pregnancy outcomes. Little is known about the influence of other atopic diseases on pregnancy outcomes. We assessed how various maternal atopic diseases might affect preterm birth, stillbirth, and neonatal death.

METHODS

By linking Norwegian national registries, we acquired information on maternal health, socio-demographic factors, pregnancy, birth, and neonatal outcome on all births in Norway from 1967 to 2003.

RESULTS

A total of 1 974 226 births were included. Of these, 1.8% had a record of maternal asthma, 3.4% of maternal atopic dermatitis, and 0.4% of maternal allergic rhinoconjunctivitis. Overall rates of preterm birth, stillbirth, and neonatal death were 6.0%, 0.6%, and 0.5%, respectively. After adjustments for possible confounders, maternal asthma was associated with increased risk of preterm birth (relative risk (RR), 1.15, [95% confidence interval (CI) 1.10, 1.21]). In contrast, maternal atopic dermatitis was associated with decreased risk of preterm birth (RR 0.90, [95% CI 0.86, 0.93]), stillbirth (RR 0.70, [95% CI 0.62, 0.79]), and neonatal death (RR 0.76, [95% CI 0.65, 0.90]). Similarly, maternal allergic rhinoconjunctivitis was associated with decreased risk of preterm birth (RR 0.84, [95% CI 0.76, 0.94]) and stillbirth (RR 0.40, [95% CI 0.25, 0.66]).

CONCLUSIONS

We confirmed the previously reported association of maternal asthma with increased risk for preterm birth. Unexpectedly, maternal atopic dermatitis and allergic rhinoconjunctivitis were associated with decreased risk of preterm birth and stillbirth. Mechanisms for these protective associations are unclear, and our findings require confirmation in further studies.

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.

Long term efficacy and safety of etanercept in the treatment of psoriasis and psoriatic arthritis

Psoriasis is a chronic, immune-mediated inflammatory disease affecting both the skin and joints. Approximately 20% of patients suffer a moderate to severe form of skin disease and up to 30% have joint involvement. Standard therapies for psoriasis include topical medications, phototherapy, and both oral systemic and biological therapies whereas therapies for psoriatic arthritis include nonsteroidal anti-inflammatory drugs followed by disease modifying antirheumatic drugs and/or tumor necrosis factor (TNF)-α inhibitors and interleukin-12/23p40 inhibitors. Treatment of both diseases is typically driven by disease severity. In the past decade, major advances in the understanding of the immunopathogenesis of psoriasis and psoriatic arthritis have led to the development of numerous biological therapies, which have revolutionized the treatment for moderate to severe plaque psoriasis and psoriatic arthritis. Anti-TNF-α agents are currently considered as first line biological therapies for the treatment of moderate to severe psoriasis and psoriatic arthritis. Currently approved anti-TNF-α agents include etanercept, adalimumab, and infliximab for psoriasis and psoriatic arthritis as well as golimumab and certolizumab for psoriatic arthritis. In this article, we aim to evaluate the long term safety and efficacy of etanercept in psoriasis and psoriatic arthritis.

Spontaneous abortion during ustekinumab therapy

BACKGROUND

Psoriasis affects a considerable proportion of women in their reproductive years. Limited published data exist about the possible negative impact of the disease itself in the prognosis of pregnancy. On this background, the emergence of newer biologic agents for psoriasis treatment - such as ustekinumab - raises safety issues concerning the exposure to the drug during pregnancy. To our knowledge this is the first report in the literature describing a pregnancy outcome under ustekinumab treatment.

OBSERVATION

We report a 35-year-old female psoriasis patient who was under treatment with ustekinumab for a year when she inadvertedly became pregnant. The drug was discontinued immediately and the patient did not opt for termination. During the 12th week of gestation she experienced a spontaneous abortion.

CONCLUSION

Although the patient's profile fulfilled 2 general risk factors for spontaneous abortion - she was a smoker and this was her third pregnancy - one could not underestimate the possible role of the drug and of psoriasis per se in this adverse pregnancy outcome. Pregnancy registries and large prospective studies are needed in order to determine whether poorer pregnancies outcomes in psoriatic women are due to the disease itself, associated comorbidities or side-effects of new therapies such as ustekinumab.
