Top in allergy/asthma: Alcohol worsens nut allergy reactions; asthma linked to suicide

Alcohol consumption may trigger worse allergic reactions in patients with nut allergies, according to a study published in International Archives of Allergy and Immunology.
The researchers found an association between alcohol consumption and severe undefined nut-induced anaphylaxis among adults who presented with anaphylaxis between 2011 and 2023. They theorize that this could be due to ethanol’s vasodilation effect, which could contribute to more severe shock from food allergy.
Additionally, alcohol consumption causes elevated acetaldehyde levels that could induce the release of histamine from airway mast cells, thereby increasing reaction severity.
“This observation raises questions about the safety of artificial flavorings in alcohol, which often contain nut-derived components, for patients with nut allergies,” Roy Khalaf, fourth-year medical student, faculty of medicine and health sciences at McGill University, told Healio.
It was the top story in allergy/asthma last week.
In another top story, adults in South Korea with asthma were 26% more likely to die by suicide compared with those who did not have asthma.
