Dr. Morrow’s Show Notes

Allergies

• When you hear someone talk about having allergies, usually they mean rhinitis or upper respiratory symptoms (runny nose, watery eyes, itching eyes and ears and nose, sneezing).
• Allergies also can be due to food, medications, animal dander or plants.

Allergic Rhinitis

• The diagnosis of allergic rhinitis should be made when history and physical findings are consistent with an allergic cause
  • g., clear rhinorrhea,
  • pale discoloration of nasal mucosa,
  • red and watery eyes
  • and one or more of the following symptoms:
    • nasal congestion,
    • runny nose,
    • itchy nose,
    • or sneezing.
  • Individuals with allergic rhinitis should be assessed for the presence of associated conditions such as
    • asthma,
    • atopic dermatitis,
    • sleep-disordered breathing,
    • conjunctivitis,
    • rhinosinusitis,
    • and otitis media.
  • Specific testing (blood or skin) should be performed for patients with a clinical diagnosis of allergic rhinitis

• • who do not respond to empiric treatment,
  • or when diagnosis is uncertain,
  • or when determination of specific target allergen is needed.

• Sinus imaging should not routinely be performed in patients presenting with symptoms consistent with allergic rhinitis.
• Intranasal steroids should be prescribed for patients with allergic rhinitis whose symptoms affect quality of life.
• Oral second-generation/less sedating antihistamines should be suggested for patients with allergic rhinitis and primary complaints of sneezing and itching.
• Intranasal antihistamines may be prescribed for patients with
  • seasonal,
  • perennial,
  • or episodic allergic rhinitis.
• Oral leukotriene receptor antagonists should not be prescribed as initial therapy for patients with AR.
• Combination pharmacologic therapy may be prescribed for patients with allergic rhinitis who have inadequate response to monotherapy.
  • The most effective combination therapy is
    • an intranasal steroid
    • and an intranasal antihistamine.
  • Immunotherapy should be prescribed for patients with allergic rhinitis who have inadequate response to pharmacologic therapy.
  • Avoidance of known allergens or environmental control may be considered in patients with allergic rhinitis who have identified allergens that correlate with their clinical symptoms.

Allergy Testing

• There are many types of allergies:
  • environmental,
  • foods,
  • drug,
• An estimated 10% to 30% of the global population has an allergic disease.
• Clinical presentations of allergic diseases, respiratory infections, and autoimmune conditions have similar features.
• Allergy and immunologic testing can help clarify the diagnosis and guide treatment.
• The allergens suspected in an allergy are identified through
  • antibody
  • or skin testing.
• For patients with an inhalant allergy, skin testing is preferred.
• In patients with food allergies, eliminating the suspected allergenic food from the diet is the initial treatment.
• If this is ineffective, antibody or skin testing can exclude allergens.
• Patients with an anaphylactic reaction to an insect sting should undergo specific antibody or skin testing.
• Skin testing for penicillin can help when penicillin administration is indicated
  • and there are limited alternatives.
  • Testing for other drug allergies has less well-determined sensitivity and specificity,
    • but can guide the diagnosis.
  • Patch testing can help identify the allergen responsible for contact dermatitis.

Food Allergies

• Patients with suspected food allergies are commonly seen in clinical practice.
• Although up to 15 percent of parents believe their children have food allergies,
  • these allergies have been confirmed in only 1 to 3 percent of all Americans.
• Family physicians must be able to separate true food allergies from
  • food intolerance,
  • food dislikes,
  • and other conditions that mimic food allergy.
• The most common foods that produce allergic symptoms are
  • milk,
  • eggs,
  • seafood,
  • peanuts,
  • and tree nuts.
• Although skin testing and blood assays may help in the evaluation of suspected food allergies,
  • they should not be performed unless the clinical history suggests a specific food allergen to which testing can be targeted.
• Furthermore, these tests do not confirm food allergy.
  • Confirmation requires a positive food challenge
    • or a clear history of an allergic reaction to a food
    • and resolution of symptoms after eliminating that food from the diet.
  • More than 70 percent of children will outgrow milk and egg allergies by early adolescence,
    • whereas peanut allergies usually remain throughout life.
  • The most serious allergic response to food allergy is anaphylaxis.
    • It requires emergency care that should be initiated by the patient or family using an epinephrine auto-injector,
      • which should be carried by anyone with a diagnosed food allergy.

• There are no recommended medications to prevent allergic reactions to food.
  • Allergen-specific immunotherapy or immunotherapy with cross-reacting allergens
    • is not recommended to treat food allergy.
  • Some environmental allergens cross-react with foods, such as:

Nonallergic Rhinitis

• Chronic nonallergic rhinitis encompasses a group of rhinitis subtypes
  • without allergic or infectious etiologies.
• Although chronic nonallergic rhinitis represents about one-fourth of rhinitis cases and impacts 20 to 30 million patients in the United States,
  • its pathophysiology is unclear
  • and diagnostic testing is not available.
• Characteristics such as no evidence of allergy or defined triggers help define clinical subtypes.
• There are several subtypes with overlapping presentations, including:
  • nonallergic runny nose,
  • senile or geriatric rhinitis,
  • gustatory rhinitis,
  • drug-induced rhinitis,
  • hormonal rhinitis, and
  • occupational rhinitis.
• Treatment is symptom-driven and similar to that of allergic rhinitis.
  • Patients should avoid known triggers when possible.
• First-line therapies include
  • intranasal corticosteroids,
  • intranasal antihistamines,
  • and intranasal ipratropium (a drying agent).
• Combination therapy with decongestants and first-generation antihistamines can be considered
  • if monotherapy does not adequately control symptoms.
• Nasal irrigation and intranasal capsaicin may be helpful but need further investigation.
