Allergic Rhinitis

What is allergic rhinitis?

Allergic rhinitis is an inflammation of the nasal mucosa which is triggered by an allergic reaction. The inflammation is caused by an excessive degranulation of mast cells. Increased IgE levels to certain allergens are thought to be responsible for this phenomenon. When exposed to these allergens, the IgE covered mast cells degranulate releasing inflammatory mediators and cytokines which results in a local inflammatory reaction.


Over the last couple of decades, there appears to have been an increase in the prevalence of allergic rhinitis. This increase is partially attributable to the limited ventilation in most modern housing. Some have also suggested pollution may have a role. Recent studies however suggest this is probably not the case. In one study comparing the rates of allergic rhinitis in two German cites, no significant difference was found despite the significantly higher levels of pollution in the eastern city.

Inciting Factors

The triggers responsible for allergic rhinitis may be classified as either seasonal or perennial. Seasonal allergens are for the most part found outdoors. Common seasonal allergens include tree, grass and weed pollens, and airborne molds. As one would suspect, these allergens depend very much on the geographic area. Perennial allergens tend to be found indoors and include among others things, dust mites and animal dander (especially from cats).

Signs and Symptoms

People suffering from allergic rhinitis usually complain of itchy eyes, nose and palate, watery rhinorrhea, nasal obstruction, sneezing attacks that are often violent and prolonged, conjunctival irritation and lacrimation. They often have edematous nasal mucosa which is classically pale or violet in colour (see Figure) and excessive clear mucus within the nose which often contains large numbers of eosinophils. Children may have a nasal skin crease as a result of chronically trying open their nasal airway, the "allergic salute".


The most important part of the physician's workup is taking a thorough history. A temporal relationship between allergen exposure and symptoms is almost diagnostic. The person who suffers all week but is fine on the weekend is very likely allergic to something at work. Skin testing is valuable to help pinpoint possible allergens but is never absolutely definitive. It should not be used to do screening without a clinical suspicion because of its high rate of false positives. In vitro tests for allergen-specific IgE are indicated for those patients with contact dermatitis or a questionable false skin test. A high serum IgE level can also provide some information but, in general, it is not sought because it is very non-specific.


The first step in managing a patient with allergic rhinitis is to educate them about the importance of avoiding allergen contact. Even the best medical therapies are ineffective in the face of a high allergen load.

Antihistamines are very effective in acute episodes. Generally, the non-sedative antihistamines are preferred to sedative ones. However, if for financial reasons the non-sedative antihistamines are not an option the patient should be instructed to take their antihistamines before bed.
Topical vasoconstrictors (see Nasal Sprays) may be added to the antihistamines for temporary relief but their use should be limited to less than 5 days to minimize the risk of developing rebound nasal congestion.
For patients with moderate disease, sodium cromoglycate may be taken prophylactically. However, this might not be popular with patients because it requires them to take medications four times a day.
When antihistamines and decongestants are insufficient or patients require daily medications, topical steroids should be considered. In general, they are very effective. Patients starting topical steroids should be taught that it takes three or four days before they will see any beneficial effects.
For severe cases, desensitization therapy has also been shown to be effective.
Surgery has a role for patients who have either septal deviations or large turbinates and chronic rhinitis.

Not all rhinitis is allergic! Check the Differential Diagnosis of Rhinitis for other ideas.

Differential Diagnosis of Rhinitis:


Seasonal allergic rhinitis (pollens)
Perennial allergic rhinitis (dusts, molds)


Idiopathic (vasomotor rhinitis)
Abuse of nasal decongestants (rhinitis medicamentosa)
Drugs (reserpine, prazosin, cocaine abuse)
Psychological stimulation (anger, sexual arousal)


Deviated septum
Hypertrophied turbinates (chronic vasomotor rhinitis)
Foreign body
CSF leak

Chronic Inflammatory

Cystic fibrosis
Wegener's granulomatosis
Midline granuloma


Acute viral infection
Acute or chronic sinusitis
Rare nasal infections: syphilis, diphtheria, leprosy, tuberculosis





Sinusitis is defined as a condition manifested by inflammation of the mucous membranes of the nasal cavity and paranasal sinuses, fluids within these cavities, and/or the underlying bone.

Clinical Criteria for Diagnosis

Major Factors

Facial pain/pressure
Facial congestion/fullness
Nasal obstruction
Nasal discharge: purulent, or discoloured postnasal drainage
Purulent discharge in nose
Fever (acute sinusitis)

Minor Factors

Dental pain
Ear pressure/fullness

In General Terms:

To diagnose sinusitis the patient must have more than 2 major factors or 1 major and 2 minor factors


Acute Sinusitis:
4 or fewer weeks in duration

Chronic Sinusitis:
More than 4 weeks in duration

Recurrent Acute Sinusitis:
Four or more episodes per year, each episode lasting at least 10 days, without signs of chronic sinusitis between

Physical Signs of Sinusitis

Swelling and erythema: maxillary, orbital, or frontal region

Anterior rhinoscopy (nasal speculum exam):
Nasal endoscopy:
Bluish colour of turbinates
Pus in middle meatus/sinus ostia
Concha bullosa (large pneumatized middle turbinate)
Anatomic anomalies (deviated nasal septum)

Inciting Factors in Sinusitis

All of these lead to sinus outflow obstruction (either anatomical or functional).

Host Factors
Allergic/immune conditions
Anatomic abnormalities
Genetic conditions
Cystic fibrosis
Immotile cilia syndrome
Systemic diseases
Environmental Factors
Infectious/viral agents
Noxious chemicals


Best imaging modality is CT (coronal and axial) to demonstrate mucosal thickening, polyps, fluid levels in sinuses, as well as underlying anatomical abnormalities predisposing to sinusitis. Plain sinus films may show opacification or air-fluid levels, but can appear normal in true sinusitis.

Other investigations depend on the clinical situation:

Patients with underlying allergic rhinitis:
Skin tests for allergies
Total IgE
Nasal secretions cytology (abundant eosinophils)
Patients with serious complications:
Cultures: antral aspiration
Patients with suspected immunodeficiency:
CBC with differential and smear
Serum immunoglobulins: IgG, IgA, IgM, IgG subclasses
Antibody titers
Delayed hypersensitivity skin tests
Other immunological tests
Patients with suspected autoimmune disorders:
Sarcoidosis: ACE levels
Wegener's granulomatosis: Antineutrophil cytoplasmic antibody (cANCA)
Patients with suspected cystic fibrosis:
Sweat test
EM of respiratory epithelium

Treatment of Acute Sinusitis

Saline nasal spray
Clears nasal crusts and thick mucus
Only in dry environments
Guard against fungal growth in the humidifier
Guaifenesin thins mucus allowing better clearance
Topical decongestants
Stimulates alpha-adrenergic receptors in nasal mucosa which vasoconstricts and shrinks swollen mucosa.
Oxymetazoline relieves nasal obstruction quickly
Short term use only
Some experimental evidence that topical decongestants result in increased mucosal inflammation, presumably by decreasing mucosal blood flow
Systemic decongestants
Helps relieve symptoms quickly
Minimal drying effects, so mucus can still be cleared
Careful with patients with other medical conditions
70% of acute sinusitis is caused by S. pneumoniae or H. influenzae
Treat for 10-14 days
Some recommended antibiotics are:
Amoxicillin or Amoxicillin-clavulanate
Clarithromycin or Azithromycin
Cefuroxime axetil
NOT Penicillin, Erythromycin, Cephalexin, Tetracycline

Treatment of Chronic Sinusitis

Antibiotics vs. Strep and Staph (Antibiotics as above plus:)
Because anaerobic bacteria are associated with chronic sinusitis
If there is an allergic component:
Avoidance of allergens
Topical nasal steroids
Topical cromolyn sodium
Systemic steroids
