MS: Breastfeeding May Offer Protection Against Postpartum Relapse

Key clinical point: Breastfeeding may prevent postpartum relapses in women with multiple sclerosis (MS). Major finding: Women with MS who breastfed had a 37% lower risk of postpartum relapse, compared with those who did not breastfeed (P = .006); exclusive breastfeeding had a greater benefit than nonexclusive breastfeeding.

Study details: A systematic review and meta-analysis of 24 studies, including 2,974 women.

Disclosures: The National Multiple Sclerosis Society supported the study through a Sylvia Lawry Physician Fellowship awarded to Dr. Krysko.
