Background: Monitoring biologic drug therapy during pregnancy in women with immune-mediated inflammatory diseases (IMIDs) is crucial to ensure treatments align with evidence-based practices.
Research Design And Methods: A retrospective cohort study based on healthcare claims data from eight Italian regions was conducted, analyzing deliveries between 2009 and 2021. The study included women receiving biologic drugs within nine months before their last menstruation. Exposures to biologics, conventional disease-modifying anti-rheumatic drugs (DMARDs) and symptom-relieving medications were assessed in the trimesters (T) before, during and after pregnancy. Factors influencing biologic treatment persistence during pregnancy were analyzed.
Results: A cohort of 1,763 deliveries was considered. Biologic drugs were prescribed for rheumatic (33.6%), dermatological (32.6%), and gastrointestinal diseases (28.4%). Biologic use declined during pregnancy (TI = 37.3%; TII = 17.6%; TIII = 11.3%), increasing again postpartum. During pregnancy, there was increased use of symptom-relieving medications for rheumatic diseases and DMARDs for gastrointestinal diseases. Factors associated with continued biologic treatment included being older than 35 years and the region of delivery.
Conclusions: This study found a decrease in biologics drug use during pregnancy and highlights the necessity for personalized therapeutic approaches. Geographic variations in biologic drug use emphasize the need for educational initiatives about the risk-benefit profiles of these therapies during pregnancy.
