What is a severe allergic rhinitis ?
Classification of allergic rhinitis*:
New classification developed in 2001 by the ARIA consensus (Allergic
Rhinitis and its Impact on Asthma) in order to characterise rhinitis and its
impact on the quality of life according to its duration (intermittent or
persistent) and the severity of the symptoms.
Intermittent
Symptoms
< 4 days per week
or < 4 weeks
Slight
• normal sleep
• normal social and leisure activities
• normal work and school life
• symptoms causing minimal discomfort
Persistent
Symptoms
> 4 days per week
and > 4 weeks
Moderate - Severe
• sleep disturbed
• disrupted social and leisure activities
• disrupted work and school life
• unpleasant symptoms

WHO – Initiative 2000
ALLERGIC RHINITIS AND ITS IMPACT ON ASTHMA (ARIA)
Allergic rhinitis has been defined by the WHO as
major chronic disease of the airways
Allergic rhinitis is a risk factor for asthma
Expand the diagnosis: think of rhinitis in patients
with asthma, think of asthma in patients with rhinitis
A common treatment strategy for rhinitis
and asthma patients is recommended!
Why the allergic patient is underdiagnosed ?
How the allergy diagnosis must be performed ?
How the GPs diagnose the allergic diseases ?
What’s going wrong with the allergy diagnosis ?
Diagnosis Process in Allergology
Patient with suspected respiratory allergy symptoms
Clinical history for allergy
Allergy testing
Skin prick-tests method
Allergens

Consultation is not frequent
“How recently have you been seen by a health care professional?”
-Internet and telephone survey
conducted in 2005 in general
population from UK, Germany, Italy
and Spain
-N=2966 randomly selected adults
with allergies
~10% of the European population with rhinitis symptoms was
never seen by a health care professional (nurse or doctor) for their
condition
Maurer M, Zuberbier T, Allergy 2007: 62: 1057-1063.
Only 1 patient over 5 consulted a specialist
TNS STUDY:
TNS survey conducted in France 2009. N= 623 subjects with AR symptoms from 2003 general
population
TYPE OF DOCTORS CONSULTED BY PATIENTS:

19% have consulted a
specialist
13%*

Allergist
5%*

*Several consultations per doctor were possible

**in France, a first consultation with a GP is
mandatory before referral to a specialist

What are the unmet needs ?
Patient expectation: a long term efficacy
Why AIT can satisfy the unmet needs ?
Immunomodulatory effect
Long term and sustained effect
Definition
Specific immunotherapy is the repeated
administration of allergen products to allergic
subjects to activate immunomodulatory
mechanisms and provide sustained relief of
symptoms during subsequent natural allergen
exposure

life due to the allergic symptoms
•

satisfied by the pharmacotherapy

Posology - arguments to increase to 8 drops per day
Patient follow up
Post graduate course: presentation and arguments
Grass rationalisation
5 Grasses / 4 cereals mixture: is it still relevant ?
High level of allergens cross-reactivity between 5 grasses
and cereals
5 grasses alone is sufficient to treat the allergic patient
sensitized to grass pollen and cereal pollen.
RATIONALE TO INCREASE TO 8 DROPS
PER DAY
STALORAL pollen: The optimal posology
Currently:STALORAL 4 press/day = 120 IR/day
ORALAIR clinical trial:
100 IR/day = No efficacy
300 IR/day = Efficacy
STALORAL 8 press/day = 240 IR/day

Patient Information/Communication
Give the right message to the patient !!
“Allergy is a chronic disease not curable by pharmacotherapy
alone..”
“Rhinitis will develop into asthma in 50 % of the patients..”
“You may develop new allergic sensitizations..”
“The only way to affect the disease is by immune
intervention..”
“ SIT is a three years treatment but compared to lifelong drug
intake..”
“ Efficacy of SIT persists longtime after cessation “
“ SIT would positivily affect your quality of life…”
Key success factors for SIT
Patient Information/Education needs from the doctor

-
Before taking the decision to Stop, Check:
Compliance :
vials renewal; missing periods : changes in personal or
familial conditions , cost issue, willingness to pursue the
treatment
Environmental changes:
increase in allergenic load/ Co-factors irritant
Co-morbidities :
not treated
If none of these factors are found, go-back to the diagnosis
and recheck the indications
Key Message
To be successful SLIT needs:
A good indication
The best candidate
An optimal patient management
