Exclusive Breastfeeding and the Effect on Postpartum Multiple Sclerosis Relapses

Area of Science:

• Neurology
• Immunology
• Reproductive Medicine

Background:

• Women with multiple sclerosis (MS) face an increased risk of relapse after childbirth.
• The impact of exclusive breastfeeding on postpartum MS relapse rates remains unclear.

Purpose of the Study:

• To evaluate the effect of exclusive breastfeeding on postpartum MS relapse risk.
• To investigate how introducing supplemental feedings influences this risk.

Main Methods:

• Prospective data collection from 201 pregnant women with relapsing-remitting MS.
• Analysis of exclusive breastfeeding (≥2 months) versus non-exclusive breastfeeding using Cox regression.
• 1-year postpartum follow-up within the German MS and pregnancy registry.

Main Results:

• Women not exclusively breastfeeding had a higher risk of relapse within 6 months postpartum (38.3% vs. 24.2%).
• Exclusive breastfeeding was associated with a reduced risk of postpartum MS relapse (adjusted hazard ratio, 1.70; P=.04).
• No significant difference in relapse time was observed after introducing supplemental feedings.

Conclusions:

• Exclusive breastfeeding appears to be a modestly effective, time-limited intervention for managing MS postpartum.
• Supporting exclusive breastfeeding for mothers with MS is recommended as it does not elevate postpartum relapse risk.
