Ice-age abrupt climate shifts were not as fast as thought, new study finds
Confirmed
In Short: A new study finds that more than one-third of infants thought to have a peanut allergy do not actually have it.
Researchers from the Murdoch Children's Research Institute and the National Allergy Centre of Excellence published their findings in The Journal of Allergy and Clinical Immunology.
The study involved infants who tested positive for a peanut allergy but were then given small, gradually increasing doses of peanuts under strict medical supervision.
Lead author Jamie Woodward, in the paper '9. Ice cores, abrupt climate shifts, and ecosystem change,' published in The Ice Age in 2014, emphasized the importance of clinical history and allergy testing.
However, the study highlights that these methods alone are not sufficient to accurately diagnose peanut allergies in many cases.
Infants who did not have an adverse reaction during the oral food challenge were considered peanut tolerant and had their allergy label removed.
The study underscores the need for more routine use of oral food challenges to confirm peanut allergy diagnoses before starting oral immunotherapy.
Further studies are needed to explore the long-term implications of these findings and to develop more accurate diagnostic tools.
