Some Misconceptions About Rhinitis
• Rhinitis is a trivial illness.
• All rhinitis is allergic.
• All non-allergic rhinitis is homogeneous.
Outline of Presentation
Practical classification of chronic rhinitis
Diagnostic approach in primary care
Specific syndromes
Distinguishing features
Treatment
Practical Classification
Allergic Rhinitis
Seasonal versus Perennial
Frequency
Persistent (> 4 days/week for > 4 weeks/year)
Intermittent (less than above)
Severity
Mild
Moderate-severe (interference with sleep or daily activities
or “troublesome symptoms”)
Other
Practical Classification: Other

Rhinitis medicamentosa

Chronic Rhinitis: Diagnostic Approach
1.History
2.Physical Exam
3.Tests
Chronic Rhinitis: Diagnostic Tests
Nasal smear (eosinophilic disease)
Specific IgE (allergic versus non-allergic)
Skin tests
RAST (blood tests)
Total IgE (AFS)
Immunoglobulins G, A, M
(hypogammaglobulinemia with chronic sinusitis)
Fungal precipitating antibody
Sinus radiology
Skin Tests versus Blood Tests
Skin Tests
Time-honored method
Results immediately available
More sensitive for some allergens or patients
Potential for systemic reactions
Antihistamines interfere
Blood tests
Easier for patient
May be more specific
No interference by medications or potential for systemic
reactions
Outline of Presentation
Practical classification of chronic rhinitis
Diagnostic approach in primary care
Specific syndromes
Distinguishing features
Treatment
Allergic Rhinitis
Distinguishing Features
Sneezing, itching, rhinorrhea prominent
May be seasonal
Triggered by freshly cut grass, cleaning house, or pet
exposure
Treatment
Indoor allergen avoidance
Intermittent: Antihistamines, intranasal corticosteroids
(INS) as needed
Persistent: Regular INS; add antihistamines (oral and/or
intranasal) and montelukast if needed)
Consider immunotherapy
Immunotherapy
Consider for patients with definite allergic
rhinitis not controlled by other means
Because of potentially life-threatening allergic
reaction, it should be carried out only by
specialists trained in its use
Goal: symptom and/or medication reduction,
not usually eradication or cure
Immunotherapy 2
Used less for rhinitis now than it used to be due
to better medications
Less effectiveness data for mold and animal
dander
One year trial
If effective, continue for 3-5 years and then
consider discontinuation
Sublingual immunotherapy (SLIT) now being
studied
Eosinophilic Non-Allergic Rhinitis
Distinguishing features
Prominent mucosal edema
Nasal eosinophilia
No relevant allergy
Treatment
Intranasal corticosteroids
Oral antihistamine or antihistamine-decongestant
combination if needed
Oral prednisone for recalcitrant disease
Nasal Polyps
Distinguishing Features
Nasal obstruction
Anosmia
Nasal polyps on exam
Treatment
Intranasal corticosteroids
Course of doxycycline (20 days)
Oral corticosteroids
Treatment of complicating infection
Consider montelukast
Surgery (polyp, sinus)
GERD Induced “Post Nasal Drip”
Distinguishing features
Feeling of post-nasal drip or mucus in throat with
minimal or no other nasal symptoms
May be associated with hoarseness, throat clearing,
cough, pyrosis, regurgitation
May be worse after eating
Treatment
Reflux precautions
Protein pump inhibitors
Practical Classification: Other
Other
Rhinitis medicamentosa
Septal deviation
Eosinophilic non-allergic rhinitis
Nasal polyps
Cholinergic rhinitis
Vasomotor rhinitis
GERD induced “post nasal drip”
Turbinate hypertrophy
Chronic
sinusitis
Symptoms Suggestive of Chronic
Sinusitis
Nasal congestion
Pain or pressure around the forehead, nose, or
eyes
Discolored nasal discharge or discolored mucus
in the throat
Reduced sense of smell
Symptoms for > 12 weeks by definition
Tomassen P, et al. Allergy 2011; 66:556
Allergy and Chronic Sinusitis
Conflicting data regarding increased prevalence
of chronic sinusitis in allergic patients
Data suggests chronic sinusitis may be more
severe in allergic patients
Appropriate to aggressively treat allergic rhinitis
in patients with coexistent chronic sinusitis
Immunotherapy not convincingly shown to
improve sinusitis in allergic patients
Medical Approach to Chronic
Sinusitis
Saline lavage
Intranasal corticosteroids
Treat acute infections
Treat coexistent allergic rhinitis
Rule out hypogammaglobulinemia
Medical treatment of hyperplastic eosinophilic
sinusitis
Post operative treatment of Allergic Fungal
Sinusitis
Chronic Hyperplastic Eosinophilic
Sinusitis
Eosinophilia does not indicate allergy
Associated with nasal polyps, asthma, aspirin
sensitivity
Poorer prognosis after surgery
Consider montelukast
Aspirin desensitization for patients with aspirin
sensitivity
Allergic Fungal Sinusitis: Diagnostic
Criteria
Radiologic evidence of sinusitis
Allergic mucin in the sinus
Fungal hyphae in the mucin or positive sinus
fungal culture
Absence of diabetes, immunodeficiency, or
immunosuppressive therapy
Absence of fungal invasion
Allergic Fungal Sinusitis:
Immunologic Findings
Elevated total IgE level (67-74 %)
May correlate with course of disease
Increases ≥ 10 % provides high sensitivity for
disease progression but lower specificity
Atopy (76-100 %)
Specific IgE against fungus (58-100 % positive
skin tests)
Precipitating antibody against fungus (8-89 %)
Allergic Fungal Sinusitis:
Management
Surgery
Post-operative prednisone
0.5 mg/kg daily for 14 days
0.5 mg/kg every other day, tapered over 3 months to
5 mg every other day
Continue 5 mg every other day for at least 12
months
Intranasal steroids
? Antifungal agents
Conclusions
Rhinitis is NOT a trivial illness
All rhinitis is NOT allergic
All non-allergic rhinitis is NOT homogeneous
Appropriate diagnosis and management (medical
and surgical) can substantially improve the
quality of life of patients with chronic rhinitis or
sinusitis and improve asthma control as well
