Pregnancy Outcomes in Women With Moderate-to-Severe Psoriasis From the Psoriasis Longitudinal Assessment and Registry (PSOLAR)

Need for individualized counseling regarding psoriasis systemic therapy in women of childbearing age: analysis of the PsoFem study at the University Medical Center Hamburg

Background

For patients with moderate-to-severe psoriasis and current childbearing/pregnancy, the choice of therapy is limited.

Objectives

The present study compared the disease burden and treatment choices in women of childbearing age (WoCBA) with and without a current wish for pregnancy.

Methods

Female patients aged 18 to 45 years, with moderate-to-severe psoriasis vulgaris, were consecutively recruited. The patients reported on sociodemographic/reproductive characteristics and quality of life impairments. The physicians assessed disease severity, comorbidities, and current treatment(s). Both patients' and dermatologists' perceptions of shared decision-making for the current systemic treatment were surveyed.

Results

Participants were 145 WoCBA with psoriasis: 73 were pregnant or reported a desire to conceive (group CB+) and 72 reported no wish to have (more) children (group CB-). Patients without childbearing wishes were older and often had previous children; no significant differences in clinical features or quality of life impairments were found. A significantly higher proportion of patients in the CB+ group were prescribed tumor necrosis factor alpha blockers, particularly certolizumab pegol. This treatment option was associated with previous children and the desire to conceive, but not with disease variables. Family planning was more often discussed and considered in the clinical decision for the CB+ group, but patient-doctor agreement for shared decision-making was fair-to-moderate.

Limitations

The small sample size prevented comparative analyses between patients planning a pregnancy in the short- vs long-term future. In addition, specific variables related to the decision-making process for the current therapy need to be assessed and examined in more detail in further research.

Conclusion

For WoCBA with childbearing wishes, tumor necrosis factor alpha blockers were most frequently prescribed, in accordance with current guidelines/recommendations. Decision-making for continuing or changing systemic therapy during pregnancy must take into account medication specificities and the vulnerable stages in pregnancy, as well as the limited amount of pregnancy-compatible drugs.

Hidradenitis Suppurativa and Maternal and Offspring Outcomes

Importance

Hidradenitis suppurativa (HS) is associated with morbidity in persons of reproductive age, but the effect on maternal and offspring outcomes is understudied.

Objective

To determine the association of HS with pregnancy outcomes and maternal and child morbidity in the long term.

Design, Setting, and Participants

This population-based longitudinal cohort study with up to 16 years of follow-up took place between 2006 and 2022 in Quebec, Canada. .

Exposure

Maternal HS.

Main Outcomes and Measures

Outcomes included hypertensive disorders of pregnancy, gestational diabetes, and other birth outcomes as well as the long-term risk of hospitalization up to 16 years after delivery. The study used adjusted log-binomial and Cox proportional hazards regression models to estimate the association between maternal HS and pregnancy outcomes or hospitalization following pregnancy. Outcomes in both mothers and offspring were assessed.

Results

There were 1 324 488 deliveries during the study, including 1332 (0.1%) among mothers with HS. Compared with patients without HS, patients with HS had a greater risk of hypertensive disorders of pregnancy (risk ratio [RR], 1.55 [95% CI, 1.29-1.87]), gestational diabetes (RR, 1.61 [95% CI, 1.40-1.85]), and severe maternal morbidity (RR, 1.38 [95% CI, 1.03-1.84]). In neonates, maternal HS was associated with risk of preterm birth (RR, 1.28 [95% CI, 1.07-1.53]) and birth defects (RR, 1.29 [95% CI, 1.07-1.56]). In the long term, HS was associated with 2.29 times the risk of maternal hospitalization (95% CI, 2.07-2.55) and 1.31 times the risk of childhood hospitalization (95% CI, 1.18-1.45), including hospitalization for respiratory, metabolic, psychiatric, and immune-related morbidity over time.

Conclusions and Relevance

This cohort study found that HS is associated with adverse maternal and offspring outcomes in the peripartum period and in the long term. Early detection and management of HS may help mitigate these outcomes.

Psoriasis in Childbearing Age: A Real-Life, Retrospective, Single-Center Study on Anti-IL17 and IL-23 Agents

Background: Psoriasis (PSO) involves about 1-3% of the population, and around 75% of women develop PSO before the age of 40. Official guidelines on the treatment of woman with anti-IL17 and anti-IL23 during this potential childbearing time are not currently available. Objective: To investigate the effectiveness and safety of biologic treatments in women of childbearing age. Methods: At the Dermatology Clinic of the University of Turin, Italy, 172 women aged 20-55 years underwent IL-17 and IL-23 inhibitor therapy for moderate-severe PSO and were followed up to 52 weeks in a real-life, retrospective, single-center study. Results: Overall, 40% of patients achieved PASI 100 at week 16, and 72% at week 52. A similar trend was observed for PASI 90 and PASI < 3 with almost 80% and 90% of patients achieving the target at 52 weeks. As for PASI 100, a statistically significant difference (p = 0.004) was found at 16 weeks, with 23.84% of patients achieving PASI 100, with IL-17 and 15.70% with the IL-23 inhibitor. No statistically significant differences were found at 28 and 52 weeks. No statistically significant differences in PASIs at any time points were recorded across the different biologic agents. Forty-six patients discontinued treatment. The most reported side effects were headache, nausea, asthenia, injection site pain, and rhinitis. Conclusions: This study showed that biologic drugs are effective and safe in women of childbearing age, with negligible side effects.

Research trends and hotspots in biologics for plaque psoriasis: A bibliometric study from 2004 to 2023

Background and objective

Biologics have revolutionized the management of plaque psoriasis and are flourishing. We aimed to construct a knowledge structure in this field through bibliometrics, analyze research trends and cutting-edge hotspots to inspire future research directions, and provide valuable references for clinical decisions.

Methods

Publications on biologics for plaque psoriasis in the Web of Science database core collection from 2004 to 2023 were searched. Bibliometric analysis and scientific knowledge mapping were performed with R, CiteSpace, and VOSviewer software.

Results

2,672 articles written by 9,474 authors from 67 countries were included in the study. The number of annual publications has steadily increased over the last 20 years. The most prolific countries, institutions, and authors were the United States, Novartis, and Prof. Reick K., respectively. Reference analysis categorized the research base of the field into 10 main clusters. "Efficacy" and "safety" were the most frequent keywords, and cluster analysis categorized the research in this area into four groups. Burst detection captured current hot keywords including interleukin (IL)-17 inhibitors, IL-23 inhibitors, "drug survival," "discontinuation," "Covid-19," "real-world," and "clinical features."

Conclusion

Global publications on biologics research in plaque psoriasis have grown steadily and rapidly over the past two decades. Efficacy and safety are the highest topics of concern for researchers, and IL-17 inhibitors, IL-23 inhibitors, real-world studies, efficacy prediction, and retreatment after biologics failure or discontinuation are current research hotspots.

Exposure to biologic therapy before and during pregnancy in patients with psoriasis: Systematic review and meta-analysis

Biologicals have transformed the management of severe disease phenotypes in psoriasis and are often prescribed in women of childbearing age. However, information on safety of biologicals in pregnancy are lacking. We conducted a systematic review and meta-analysis aimed to describe the characteristics and pregnancy outcomes in women with psoriasis exposed to biologics within 3 months before or during pregnancy, and to estimate the pooled prevalence of spontaneous, elective and total abortions, and congenital malformations in their newborns. Bibliographic searches were performed in the PubMed, Embase, Scopus and Web of Science databases up to 14 April 2022. No restrictions on sample size or publication date were applied. Review performance complied with PRISMA guidelines, and two reviewers assessed randomized controlled trials and nonrandomized studies reporting pregnancy outcomes in women exposed to biologics indicated for psoriasis during the pre-gestational and/or gestational period. Studies focusing on rheumatologic or gastroenterological immune-mediated inflammatory diseases were excluded. Regardless of data heterogeneity, a random-effects model was used to pool prevalence estimates. We included 51 observational studies, involving 739 pregnancies exposed to approved biologics for psoriasis. Administration was mostly (70.4%) limited to the first trimester, and the most common drug was ustekinumab (36.0%). The estimated prevalence of miscarriage was 15.3% (95% confidence interval [CI] 12.7-18.0) and elective abortions, 10.8% (95% CI 7.7-14.3). Congenital malformations occurred in about 3.0% (95% CI 1.6-4.8) of live births exposed to biologics during pregnancy. Altogether, exposure to biologics for psoriasis during pregnancy and/or conception does not seem to be associated with an increased risk of miscarriage/abortion or congenital malformations, showing similar rates to the general population. These results suggest that biologic drugs are safe and pose an acceptable risk to the foetuses/neonates.

Efficacy and safety of biological agents for the treatment of pediatric patients with psoriasis: A bayesian analysis of six high-quality randomized controlled trials

Background

Biological agents have been used with extreme caution in children because of their possible adverse effects.

Objectives

This study used high-quality randomized controlled trials (RCTs) to provide high-level evidence to assess the effectiveness and safety of biological agents for treating children with psoriasis.

Methods

We searched PubMed, Embase, Cochrane, and Web of Science databases through October 31, 2021. We included trials reporting at least one adverse event after treatment with biological agents of patients less than 18-year-old diagnosed with psoriasis. RevMan 5.3 and Stata 15.0 software were used for meta and Bayesian analyses.

Results

Six trials with 864 participants were included in the analysis. The results showed a 2.37-fold higher response rate in all biologics groups than in the control group for psoriasis area and severity index 75 (PASI75) (RR= 2.37, P-value < 0.01, 95% confidence interval [CI] [1.22, 4.62]). Compared with placebo, the PASI75 response rates of etanercept (RR= 2.82, 95% [CI] [1.10, 7.21]), ustekinumab low dose (RR= 7.45, 95%[CI] [1.25, 44.58]), and ustekinumab high dose (RR= 7.25, 95%[CI] [1.21, 43.41]) were superior. Additionally, the incidence of total adverse reactions was 1.05 times higher for biologics than for controls, indicating a good safety profile (RR= 1.05, P-value = 0.53, 95%[CI] [0.92, 1.19]). Overall, these six high-quality randomized controlled trials suggest that biologics are effective and safe for pediatric patients with psoriasis.

Limitations

Inclusion of few relevant, high-quality RCTs.

Conclusion

The results of this study indicate that biologics can be used to treat children with moderate-to-severe psoriasis without the risk of adverse effects. Ustekinumab showed the best efficacy and the fewest adverse effects.

Pregnancy outcomes following periconceptional or gestational exposure to ustekinumab: Review of cases reported to the manufacturer's global safety database

BACKGROUND

Ustekinumab, a human immunoglobulin G1 monoclonal antibody that binds to and inhibits interleukin (IL)-12/IL-23, is indicated for multiple immune-mediated diseases. Ustekinumab is actively transported across the placenta and theoretically could impact pregnancy outcomes. Limited data on pregnancy outcomes with ustekinumab exposure are available.

AIM

To assess pregnancy outcomes in patients exposed to ustekinumab during pregnancy METHODS: Cumulative data on medically confirmed ustekinumab-exposed pregnancies from the manufacturer's Global Safety Database were summarised. Descriptive data for pregnancy outcomes were presented overall and by patient subgroups.

RESULTS

As of 31 August 2020, 408 medically confirmed, prospective, maternal ustekinumab-exposed pregnancies with reported outcomes were identified. The mean maternal age was 31 years. Of the 420 pregnancy outcomes (including 4 sets of twins),^{a , b} 340 (81%) were live births, 51 (12.1%) spontaneous abortions, 25 (6%) elective/induced abortions, 3 (0.7%) stillbirths and 1 (0.2%) ongoing pregnancy with foetal congenital anomaly (CA). Among 340 live births, 33 (9.7%) were born pre-term. The rate of major CAs was similar by indication (Crohn's disease vs psoriasis), ustekinumab dose (45 mg vs 90 mg) and timing and duration of maternal exposure to ustekinumab. Prospective outcomes of pregnancies with paternal periconceptional ustekinumab exposure (n = 87) included 92% live births (1.2% major CA), 5.7% spontaneous abortions and 2.3% elective/induced abortions.

CONCLUSIONS

Rates of adverse pregnancy outcomes or CAs with ustekinumab exposure were consistent with rates reported for the US general population and do not suggest a higher risk associated with maternal or paternal exposure to ustekinumab.

Ustekinumab Exposure in Pregnant Women From Inflammatory Bowel Disease Clinical Trials: Pregnancy Outcomes Through Up To 5 Years in Crohn's Disease and 2 Years in Ulcerative Colitis

Background

While no adverse developmental outcomes were observed in preclinical animal studies, limited data exist regarding effects of ustekinumab on human pregnancies. Previously, no data have been reported for women treated with ustekinumab in inflammatory bowel disease (IBD) clinical trials and corresponding pregnancy outcomes. Here, we present pregnancy outcomes from IBD clinical trials, incorporating 5 years of treatment in Crohn's disease (CD) and 2 in ulcerative colitis (UC).

Methods

All patients in the clinical trials agreed to use adequate birth control and were discontinued from treatment upon pregnancy confirmation. Nonetheless, 39 pregnancies occurred with maternal ustekinumab exposure from 4 CD and 1 UC study. Maternal and neonatal outcomes and data are presented with summary statistics, where available.

Results

Of 1289 women who received ≥1 dose of ustekinumab, 39 maternal pregnancies with outcomes were reported (pregnancy cohort). Median maternal age was 28.0 years and median duration of ustekinumab treatment before pregnancy was 63.7 weeks with the last dose of ustekinumab administered prior to or during the first trimester (terminal half-life of ~3 weeks). Outcomes for the 39 pregnancies were: 26 live births (all normal newborns), 8 spontaneous abortions, and 5 elective abortions. No congenital anomalies were reported among normal newborns and no safety signals emerged with neonatal outcomes.

Conclusions

Based on this series of 39 pregnancies with outcomes from IBD clinical trials, mothers treated with ustekinumab (limited to up to the first trimester) did not demonstrate a risk of negative outcomes. More data are needed to characterize the safety profile of ustekinumab use during pregnancy.

Fetal and maternal outcomes after maternal biologic use during conception and pregnancy: A systematic review and meta-analysis

BACKGROUND

Biologic medications, specifically tumour necrosis factor-α (TNF-α) inhibitors, have become increasingly prevalent in the treatment of chronic inflammatory disease (CID) in pregnancy.

OBJECTIVE

To determine pregnancy outcomes in women with CID exposed to biologics during pregnancy.

SEARCH STRATEGY

PubMed and EMBASE databases were searched through January 1998-July 2021.

SELECTION CRITERIA

Peer-reviewed, English-language cohort, case-control, cross-sectional studies, and case series that contained original data.

DATA COLLECTION AND ANALYSIS

Two authors independently conducted data extraction. A meta-analysis of proportions using a random-effects model was used to pool outcomes. Linear regression analysis was used to compare the mean of proportions of outcomes across exposure groups using the 'treated' group as the reference category. All studies were evaluated using an appropriate quality assessment tool. The GRADE approach was used to assess the overall certainty of evidence.

MAIN RESULTS

Thirty-five studies, describing 11 172 pregnancies, were eligible for inclusion. Analysis showed pooled proportions for congenital malformations as follows: treated 0.04 (95% CI 0.03-0.04; I2  = 77) versus disease-matched 0.04 (95% CI 0.03-0.05. I2  = 86; p = 0.238); preterm delivery treated 0.04 (95% CI 0.10-0.14; I2  = 88) versus disease-matched 0.10 (95% CI 0.09-0.12; I2  = 87; p = 0.250); severe neonatal infection: treated 0.05 (95% CI 0.03-0.07; I2  = 88) versus disease-matched 0.05 (95% CI 0.02-0.07; I2  = 94; p = 0.970); low birthweight: treated 0.10 (95% CI 0.07-0.12; I2  = 93) versus disease-matched 0.08 (95% CI 0.07-0.09; I2  = 0; p = 0.241); pooled miscarriage: treated 0.13 (95% CI 0.10-0.15; I2  = 77) versus disease-matched 0.08 (95% CI 0.04-0.11; I2  = 5; p = 0.078); pre-eclampsia; treated 0.01 (95% CI 0.01-0.02; I2  = 0) versus disease-matched 0.01 (95% CI 0.00-0.01; I2  = 0; p = 0.193). No statistical differences in proportions were observed. GRADE certainty of findings was low to very low.

CONCLUSION

We demonstrated comparable pregnancy outcomes in pregnancies exposed to biologics, disease-matched controls and CID-free pregnancies using the GRADE approach.

The impact of gender and sex in psoriasis: What to be aware of when treating women with psoriasis

Psoriasis is a common chronic inflammatory skin disease with an exceptionally high burden for women.

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.

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.

Pharmacovigilance pregnancy data in a large population of patients with chronic inflammatory disease exposed to certolizumab pegol

Introduction:

Chronic inflammatory diseases (CIDs), including rheumatic diseases and other inflammatory conditions, often affect women of reproductive age. Tumor necrosis factor inhibitors (TNFi) are widely used to treat CID, but there is limited information on outcomes of TNFi-exposed pregnancies. We evaluated pregnancy outcomes from 1392 prospectively reported pregnancies exposed to certolizumab pegol (CZP), a PEGylated, Fc-free TNFi with no to minimal placental transfer.

Methods:

CZP-exposed pregnancies in patients with CID from the UCB Pharmacovigilance global safety database were reviewed from the start of CZP clinical development (July 2001) to 1 November 2020. To limit bias, the analysis focused on prospectively reported cases with known pregnancy outcomes.

Results:

In total, 1392 prospective pregnancies with maternal CZP exposure and known pregnancy outcomes (n = 1425) were reported; 1021 had at least first-trimester CZP exposure. Live birth was reported in 1259/1425 (88.4%) of all prospective outcomes. There were 150/1425 (10.5%) pregnancy losses before 20 weeks (miscarriage/induced abortion), 11/1425 (0.8%) stillbirths, and 5/1392 (0.4%) ectopic pregnancies. Congenital malformations were present in 30/1259 (2.4%) live-born infants, of which 26 (2.1%) were considered major according to the Metropolitan Atlanta Congenital Defects Program criteria. There was no pattern of congenital malformations.

Discussion and conclusion:

No signal for adverse pregnancy outcomes or congenital malformations was observed in CZP-exposed pregnancies. Although the limitations of data collected through this methodology (including underreporting, missing information, and absence of a comparator group) should be considered, these data provide reassurance for women with CID who require CZP treatment during pregnancy, and their treating physicians.

Impact of Psoriasis and Hidradenitis Suppurativa in Pregnancy, a Systematic Review

Psoriasis and hidradenitis suppurativa (HS) are chronic inflammatory skin diseases that frequently develop in young women. The aim of this study is to evaluate how hidradenitis suppurativa and psoriasis impact women desiring to conceive, and their influence on fertility and gestation. A systematic review of articles dating from January 2015 to April 2021 was performed using the Scopus (Elsevier) database. The search terms were (psoriasis and (birth or pregnancy or fertility)) and ((hidradenitis suppurativa or acne inversa) and (birth or pregnancy or fertility)). The search was limited to human data. Systematic reviews, case reports, clinical practice guidelines, expert consensus and conference papers were excluded. The impact of HS on pregnancy includes an impaired desire for pregnancy, a decrease in fertility, the worsening of the disease during pregnancy and potential adverse events during pregnancy. Moreover, the pregnancy might imply a change on the treatment of HS. The impact of psoriasis on pregnancy includes a decrease in fertility, potential adverse events during pregnancy and an unpredictable evolution of the disease. Moreover, the pregnancy might imply a change on the treatment of psoriasis, although biologic therapies do not appear to increase the risk of adverse events. In conclusion, both HS and psoriasis have an impact on pregnancy. A decrease of fertility has been reported. Moreover, both diseases have an unpredictable evolution during pregnancy. Pregnant women who are under biologic therapy do not seem to have a higher rate of adverse events. Treatment of both conditions is usually halted during pregnancy since scientific evidence about their safety is not conclusive, or teratogenic risk has been proven.

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. 

[Current aspects of antirheumatic therapy in pregnancy planning, during pregnancy and breastfeeding]

Active rheumatic disease is a known factor for increased fetomaternal risks during pregnancy. Remission or inactive disease should therefore be targeted to reduce these risks by using pregnancy-compatible antirheumatic drugs as recommended by international guidelines. Teratogenic antirheumatic drugs, such as mycophenolate, methotrexate, cyclophosphamide and thalidomide should be stopped about 3 months prior to conception. Leflunomide is a weak human teratogen that should be stopped and eliminated with cholestyramine prior to conception. Furthermore, drugs with limited data, such as apremilast and JAK inhibitors as well as new biologics should be avoided during gestation. Pregnancy-compatible drugs are the antirheumatic drugs hydroxychloroquine, sulfasalazine, azathioprine, cyclosporine, tacrolimus, colchicine, non-selective NSAIDs, low-dose prednisone/prednisolone and TNF inhibitors. These drugs as well as other biologics, such as rituximab can be used during lactation. In a preconception counselling visit, the benefits and the international recommendations of pregnancy-compatible antirheumatic drugs should be discussed with the patient and be weighed against the possible fetomaternal risks of an active disease to enable a shared decision-making.

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.
