Can Breastfeeding Protect from Multi-System Inflammatory Syndrome in Children (MIS-C)? A Preliminary Study

Le résumé fourni par la source

BACKGROUND: Breastfeeding prevents Kawasaki disease (KD), as well as several autoimmune disorders. Since there is an overlap between the Multi-System Inflammatory Syndrome in children following SARS-CoV-2 infection (MIS-C) and KD, this case series aims to analyze the association between breastfeeding and MIS-C. METHODS: A series of 16 cases of children with MIS-C admitted to three pediatric facilities between January 2021 and May 2022 were conducted. Breastfeeding rate was estimated through the Brief Breastfeeding and Milk Expression Recall Survey. RESULTS: Out of 16 children, 9 (56%) had been breastfed at birth. DISCUSSION: Our breastfeeding rate is below the median Spanish rate for initial breastfeeding. These findings do not clearly support the hypothesis that breastfeeding might prevent MIS-C. CONCLUSION: Contrary to the role of breastfeeding in KD prevention, our case series cannot answer with certainty the question about whether or not breastfeeding does protect children against MIS-C. These findings require confirmation in larger studies.
