Peanut Allergy: A Lifelong Threat to Take Seriously
Early introduction in infancy reduces later allergy.
Dr. Sophie Renard
Allergist
Hives, lip/tongue swelling, throat tightness, wheezing, abdominal pain, vomiting, hypotension. Symptoms can appear within minutes.
Diagnosis
Specific IgE and component testing (Ara h 2) help confirm true allergy versus sensitisation. Oral food challenge is the gold standard.
Emergency action
Adrenaline (intramuscular thigh) is first-line for any suspected anaphylaxis. Antihistamines are not a substitute.
Prevention
LEAP and EAT studies showed introducing peanut foods between 4-11 months sharply reduces peanut allergy in at-risk infants.
Oral immunotherapy is now an option for selected children to reduce the severity of reactions to accidental exposure.
