BACKGROUND: Relapse risk after delivery is increased in women with active multiple sclerosis (MS), the best strategy to reduce it is unknown. We aimed to assess the association of four different postpartum strategies with relapses during the first 6 months post partum.

METHODS: This cohort study includes data prospectively collected through structured telephone interviews from the German Multiple Sclerosis and Pregnancy Registry. Pregnancies with active MS (fingolimod or natalizumab treatment OR relapse within 1 year before pregnancy) and postpartum follow-up of ≥6 months were included. We compared four strategies: (1) intention to breastfeed exclusively without disease-modifying therapy (DMT) (exclusive breast feeding ≥2 months or switching to non-exclusive/weaning within 2 weeks after a relapse during the first 2 months), (2) early treatment with natalizumab/fingolimod and (3) other DMT initiated within 6 weeks post partum before a relapse. If women did not or only partially breastfed, or started DMT≤6 weeks after delivery after a relapse or later, we assumed (4) no-DMT-no-exclusive- breastfeeding-strategy. Main outcome was time to postpartum MS relapses.

RESULTS: In 867 women with 911 pregnancies, most (n=416) intended to breastfeed exclusively or had no-DMT-no-exclusive-breastfeeding-strategy (n=290); fewer started fingolimod (n=38), natalizumab (n=74) or another DMT (n=93) early. Recurrent time-to-event analysis showed a statistically significant reduction in relapse hazard only with the natalizumab/fingolimod-strategy as of months 3-4 post partum compared with intention-to-breastfeed-exclusively-strategy. The very early relapse risk was highest in no-DMT-no-exclusive-breastfeeding-strategy.

CONCLUSION: In active MS, an early postpartum treatment strategy should be determined well before delivery. Natalizumab/fingolimod-strategy reduced postpartum relapse hazard from month 3, but none diminished the early postpartum relapse hazard.
