Background:
Allergen immunotherapy (AIT) is a safe, effective and disease-modifying treatment for allergic rhinitis. It is indicated for children with moderate to severe disease whose symptoms persist despite conventional therapy. There is a high prevalence of allergic rhinitis amongst Irish children; however, levels of AIT prescribing in Ireland are lower than neighbouring countries.
Aims:
The aims of this study are to describe current patterns of AIT prescribing and referrals amongst Irish paediatricians and to identify barriers to accessing AIT in Ireland.
Methods:
An electronic questionnaire was distributed to all paediatricians and paediatric trainees caring for children with allergic rhinitis.
Results:
A lack of knowledge of AIT clinical criteria was the most frequently reported barrier with 50.5% (50/99) of general paediatricians unaware of the indications for referral compared to 27.3% (3/11) of respiratory physicians and 0% (0/8) of allergists. Accessibility is the next most cited barrier with 31.4% (37/118) of respondents unsure where to refer and 19.5% (23/118) reporting a lack of local services. Cost was reported to be a barrier by 12.7% (15/118). Paediatricians with an allergy or respiratory subspecialisation reported seeing significantly higher numbers of children with allergic rhinitis and were more likely to prescribe or refer a child for AIT.
Conclusions:
This study demonstrated positive attitudes towards AIT amongst all grades and specialities of paediatricians in Ireland. The main barriers to more widespread use are difficulties with the identification of suitable candidates by general paediatricians and a lack of local AIT services and referral pathways.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Hypersensitivities
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...
