A Woman with Rheumatoid Arthritis Who Successfully Delivered a Healthy Child with Continuous Administration of Sarilumab Throughout Pregnancy

Abstract

We herein report a patient with rheumatoid arthritis (RA) who successfully delivered a healthy child with continuous administration of sarilumab throughout pregnancy. She delivered her first child, a healthy boy, following in vitro fertilization-embryo transfer (IVF-ET) while using etanercept and low-dose prednisolone. Disease activity persisted after delivery, so etanercept was switched to sarilumab. She became pregnant by IVFET again. Because RA was still active, sarilumab was continued during pregnancy. She delivered a healthy girl at the 38th week of gestation by Caesarean section. No abnormalities were detected at or within 6 months after birth. Sarilumab was safe and effective in this pregnant woman with RA.
