A new study correlates SIDS to a biological marker present in normal amounts babies at birth for babies who survive and lower in babies who don’t.
BChEsa, measured in dried blood spots taken 2-3 days after birth, was lower in babies who subsequently died of SIDS compared to surviving controls and other Non-SIDS deaths. We conclude that a previously unidentified cholinergic deficit, identifiable by abnormal -BChEsa, is present at birth in SIDS babies and represents a measurable, specific vulnerability prior to their death.Carmel Therese Harrington, Naz Al Hafid, Karen Ann Waters, Butyrylcholinesterase is a potential biomarker for Sudden Infant Death Syndrome, eBioMedicine, Volume 80, 2022, 104041, ISSN 2352-3964, https://doi.org/10.1016/j.ebiom.2022.104041.
Correlation does not mean causation, but it is an intriguing area for more exploration to find a solution to a devastating problem for parents.
Parents receive a lot of sometimes contradictory advice on how to prevent SIDS. And should they lose a child to it, they could wonder what they did wrong.
