previous years Now having lots of problems with
sneezing and coughing in the mornings

Jack
Initially Jack would get wheezy in winter months usually associated with URTI or when playing in evening when cold air. He has only ever used Salbutamol as needed. He does not use a spacer. He required one 3 day course of prednisone last winter.
For the last 6 months he has been getting short of breath when playing footy or soccer and will have to stop to catch his breath.
He is coughing every morning and wakes a couple of times a week at night.

His mother asks could milk be the cause of his nasal symptoms?
What do you think might be implicated in his AR?

How will you manage his AR?
Investigations – SPT – RAST
Avoidance strategies – Bedding – Toys – Carpets – Pets

Treatment of allergic rhinitis
Pharmacotherapy – Nasal corticosteroids – Antihistamines – Immunotherapy – Other

Is there any relationship between asthma and AR?
A. Yes B. No

ARIA
The link between Asthma and Allergic Rhinitis
![Page 29: Nothing to sneeze at - allergic rhinitis and the impact on asthma · 2018. 11. 17. · Asthma and allergic rhinitis frequently coexist Asthma – 3-5% of general population – 20-40%](https://reader033.vdocuments.us/reader033/viewer/2022052011/60277e30414a2378b370bc43/html5/thumbnails/29.jpg)
ARIA – United airway disease
Asthma and allergic rhinitis frequently coexist Asthma
– 3-5% of general population – 20-40% of people with a history of AR
Up to 80% of people with asthma have nasal allergy symptoms versus 20% in the general population
Treatment of one condition can improve control of the other
![Page 30: Nothing to sneeze at - allergic rhinitis and the impact on asthma · 2018. 11. 17. · Asthma and allergic rhinitis frequently coexist Asthma – 3-5% of general population – 20-40%](https://reader033.vdocuments.us/reader033/viewer/2022052011/60277e30414a2378b370bc43/html5/thumbnails/30.jpg)
Implications for management
Treatment of rhinitis can reduce asthma symptoms
Intranasal corticosteroids reduce need for asthma-related hospitalisation
– Risk of asthma related event (DEM presentation or admission) half in those treated for AR compared with those untreated

Think about AR in patients with asthma
Examine the nose and recognise signs of rhinitis
Ask about specific symptoms Routinely ask about symptom control Provide advice about minimising known
rhinitis triggers
