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.
