Key clinical point: Discontinuation of biologic disease-modifying antirheumatic drugs (bDMARD) upon testing positive for pregnancy is associated with and a major risk factor for disease flare during pregnancy in a large proportion of women with rheumatoid arthritis (RA) and good disease control prior to conception.
Major finding: Overall, flare was reported by 37% of patients during pregnancy and was associated with discontinuing bDMARD upon testing positive for pregnancy (odds ratio [OR] 2.857; P = .034) and previous use of >1 bDMARD (OR 4.1; P = .019). Patients with vs without disease flare during pregnancy were more likely to report preterm delivery (27% vs 7%; OR 4.625; P = .034).
Study details: This study analyzed the retrospectively collected data of 73 pregnancies in 63 women with RA and good disease control during conception who were prospectively followed through their pregnancies.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
