The New England Journal of Medicine published a study on the rate of pregnancy-related relapse in multiple sclerosis (MS). The study followed 254 women with MS across 12 European countries, examining 269 pregnancies. The women were monitored during their pregnancies and for up to 12 months postpartum to assess relapse rates and disability scores. The results showed that the relapse rate decreased during pregnancy, especially in the third trimester, and increased in the first three months postpartum before returning to the pre-pregnancy rate. The Kurtzke Expanded Disability Status Scale (EDSS) scores, which measure disability, did not worsen significantly during the postpartum period. Neither epidural analgesia nor breastfeeding was found to increase the risk of relapse or disability progression. The study concluded that pregnancy is associated with a reduced relapse rate in MS, particularly in the third trimester, followed by an increase in the first three months postpartum. The findings suggest that MS activity may be influenced by hormonal changes during pregnancy, with a possible shift toward increased humoral immunity. The study highlights the importance of understanding the impact of pregnancy on MS and its potential implications for treatment and management strategies.The New England Journal of Medicine published a study on the rate of pregnancy-related relapse in multiple sclerosis (MS).
