Key clinical point: Pregnancy may have a protective effect on the risk of developing multiple sclerosis (MS) in addition to a hypothesized reverse causality.
Major finding: Women with MS vs. women without any autoimmune disease were less likely to record the 18 pregnancy-related gynecological International Classification of Diseases 10th Revision codes, with strongest negative correlation observed for the supervision of normal pregnancy (adjusted P = 9.12 × 10−27) and high-risk pregnancy (adjusted P = 2.49 × 10−12).
Study details: Findings are from a retrospective case-control study including women with newly diagnosed MS (n = 5720) and three control cohorts of women with newly diagnosed Crohn’s Disease (n = 6280), psoriasis (n = 26,729), and women without any of the three autoimmune diseases (n = 40,555).
Disclosures: The study was funded by European Union’s Horizon 2020 Research and Innovation Program, Hertie Foundation, and the Hans and Klementia Langmatz Stiftung, among others. B Hemmer declared serving on scientific advisory boards and receiving speaker honoraria and research funding from various sources. The other authors declared no conflicts of interest.
