Teenagers with asthma at increased risk of life-threatening anaphylaxis

Teenagers with food allergy are four times more likely to report having asthma than those without food allergy. People with multiple food allergies report 10 times the incidence.

According to Professor Katie Allen, the concern is that for these teens, an anaphylactic reaction may be more likely to be mistaken for an asthma attack, resulting in delayed administration of an adrenaline (epinephrine) autoinjector and increasing the risk of fatal attacks.

“When someone has both asthma and a severe food allergy, an allergic reaction can easily be mistaken for an asthma attack. Instead of immediately administering adrenaline (epinephrine) valuable time can be wasted administering the asthma inhaler.

“Teens and young adults are already identified as a high risk group for fatal anaphylaxis. This new research adds even greater emphasis on the importance of education and resources around teens with allergy. Not just for the allergy sufferers themselves, but for their families, friends, schools, food outlets, sporting clubs and the wider community.

“The importance of people recognising anaphylaxis and administering adrenaline cannot be stressed enough,” said Professor Allen. 

Heartbreakingly, for 15-year-old Jack Irvine, the combination of anaphylaxis and asthma were factors contributing to the young schoolboy’s death in 2012. Suffering from nut allergies and asthma, Jack inadvertently ate a biscuit containing macadamia nuts while attending a catered go-karting camp. Jack thought he was eating white chocolate chips.

Jack had a delay in onset of symptoms and when they appeared they were interpreted as asthma. It was not until an ambulance arrived that Jack’s father realised the reaction was anaphylaxis. Jack tragically passed away in hospital six days later.

The new research and Jack’s story was shared at the launch of Food Allergy Week 2016. According to Maria Said, President of Allergy & Anaphylaxis Australia (A&AA) Jack’s story tragically shows why ongoing allergy education is so important and why it needs the support of the entire community.

“Australia has one of the highest rates of food allergy in the world and the incidence continues to grow at an alarming rate. With such a rapid increase in food allergy over the last 10 to 15 years, our current generation of teenagers is one of the fastest growing demographics for allergy management,” commented Ms. Said. 

Food Allergy Week runs from 15 May to 21 May and continues to help raise awareness of the prevalence of food allergies and best ways communities can work together to support people with food allergy to minimise risk and help manage emergencies when they happen.

“There are approximately 30,000 new cases of food allergy in Australia each year and the incidence is increasing. Experts estimate that if the prevalence of allergy continues to increase at the current rate, there will be 7.7 million Australians with allergy by 2050.

 “With so many people at risk, food allergy is a challenge for us all; we need to learn from each other and follow best practise. This is a community concern that needs to be managed by everyone involved – children, teens and young people especially cannot do it on their own,” concluded Said.
