In utero exposure to biologic disease-modifying anti-rheumatic drugs and effects to the infant: infectious complications, vaccine response, and safety of live vaccine administration

Abstract

Introduction: Biologic disease-modifying anti-rheumatic drugs (bDMARDS) are increasingly used in clinical practice for a variety of conditions. Due to concerns surrounding persistence of drug levels and resulting immunosuppression, current case reports recommend against live vaccine administration in the first year of life for an infant exposed to perinatal bDMARDS. As a result, this significantly impacts receipt of rotavirus vaccination, a vaccine recommended in many countries' national immunization program. Area covered: We have reviewed all available published literature to explore the effect of peripartum bDMARDS exposure on infant immune responses, safety of live vaccines, and vaccine efficacy in the first year of life. Expert opinion: We recommend that otherwise healthy newborns with a history of perinatal exposure to bDMARDS should receive rotavirus vaccinations as per the recommended schedule. Bacille Calmette et Guerin vaccine should be withheld in the first year of life. No additional booster doses of inactivated vaccines are required as they appear to mount adequate immune responses to the routine schedule.Date of Electronic Publication: 2019 Apr 05.
