The use of biologics in women with psoriasis who are either pregnant or planning to conceive is not associated with an increased risk of miscarriage, abortion or congenital malformations, according to the findings of a recent study.
The available literature suggests that psoriasis improves during pregnancy although there is a slight risk of a disease flare following delivery. Although biologics are used for patients with moderate to severe psoriasis, the continued use of biologic therapy in pregnancy is a difficult decision to make because of the lack of safety data. Moreover, these decisions are further hampered by the fact that pregnant women are invariably excluded from clinical trials using biologics.
With uncertainty over the safety of biologics in pregnancy, in the current study, published in Journal of the European Academy of Dermatology and Venereology, Spanish researchers conducted a systematic review and meta-analysis to examine examine pregnancy outcomes in women with psoriasis exposed to biologics within three months before or during pregnancy. The team also included studies where women were planning to conceive and who were exposed to biologics.
Biologics and outcomes
A total of 51 observational studies in women with a mean age of 30.3 years and with 739 pregnancies exposed to approved biologics were included in the analysis. In most cases (70.4%) the biologics were administered during the first trimester, with the most common agent being ustekinumab (36.0%), followed by etanercept (19.3%). However, there were no studies with newer agents such as brodalumab, risankizumab or bimekizumab.
The estimated prevalence of miscarriage was 15.3% (95% 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. These estimates were similar to those reported in the general population.
The researchers concluded that biologics used in psoriasis are safe and pose an acceptable risk to foetuses and neonates.
