A recent study has identified 14 biomarkers that could potentially predict the risk of sudden infant death syndrome (SIDS) in infants. SIDS is a perplexing condition that has baffled doctors for years.
The researchers analyzed data from over 350 infants who tragically died from SIDS and compared them to a control group of over 1,400 babies who did not succumb to SIDS.
Interestingly, the study also found that infants born to Hispanic and Asian mothers had the lowest risk of SIDS.
SIDS refers to the sudden, unexplained death of a newborn under the age of one, often occurring during sleep. While its exact cause remains unknown, it is believed that infants who die from SIDS have underlying issues related to stress responses, heart rate regulation, breathing, and temperature control.
One significant finding of this study is the association between lower levels of certain metabolites in infants who experienced SIDS compared to those who did not.
The researchers particularly emphasize the importance of acylcarnitines in identifying the likelihood of SIDS. Acylcarnitines play a vital role in transporting fatty acids for energy metabolism, and atypical levels may indicate systemic dysfunction in this process.
According to Warsh, a researcher involved in the study, abnormalities in energy metabolism could result in insufficient energy supply to critical tissues such as the brain and heart, potentially contributing to sudden death.
Furthermore, two other metabolites stood out in this research: 17-hydroxyprogesterone and tyrosine. Elevated levels of 17-hydroxyprogesterone may indicate a disrupted endocrine system, which can affect breathing and stress responses. Tyrosine is involved in the production of neurotransmitters that regulate stress and emotional responses, such as dopamine and norepinephrine.
