Key clinical point: Methotrexate use before conception increased the risk for pregnancy losses and abortion in childbearing-age women with rheumatoid arthritis (RA), with the risk for elective termination of pregnancy (ETOP) being significantly higher with methotrexate use in the period close to conception.
Major finding: Methotrexate use any time before conception was significantly associated with a higher risk for pregnancy losses (adjusted odds ratio [aOR] 2.22; P < .001) and abortion (aOR 1.76; P < .01) in women with vs without RA, with the risk for ETOP being almost 4-fold higher with methotrexate use in the 3-month window before conception (aOR 4.77; P < .05).
Study details: Findings are from a retrospective cohort study including childbearing-age women with RA who did (n = 223) and did not (n = 323) receive methotrexate and those without RA who did not receive methotrexate (n = 1690).
