Leilani St. Intranasal steroids improve subjective eye symptom scores as well as or better than oral antihistamines in adults who also have allergic conjunctivitis SOR: Asystematic review, RCTs. The most commonly measured outcomes in allergic rhinitis and conjunctivitis trials are symptom scales, which are neither standardized nor clinically validated. Steroids provide more relief of nasal symptoms A meta-analysis of 21 randomized placebo-controlled trials total patients, average age mids that compared changes in TNSS with intranasal steroids and oral antihistamines among adults with seasonal allergic rhinitis found that steroids reduced TNSS more than antihistamines.
Two drug company-sponsored RCTs patients combined, average age 30s, moderate to severe allergic rhinitis published before the meta-analysis also demonstrated that the intranasal steroid fluticasone propionate modestly reduced TNSS compared with the oral antihistamine fexofenadine 1 point vs 1. Results for eye symptoms are mixed A meta-analysis of 11 RCTs patients, average ptact 32 showed no significant difference in relief of eye symptoms between oral antihistamines dexchlorpheniramine, terfenadine, and loratadine and intranasal steroids budesonide, beclomethasone, fluticasone, and triamcinolone in patients with seasonal allergies, as measured by various symptom scores.

However, local and systemic reactions may occur. Local reactions, such as redness or itching at the injection site, can generally be managed with local treatment e.
The most severe reaction is anaphylaxis. Fatal anaphylactic reactions are rare, occurring in an estimated 1 in immunol 8 million doses of immunotherapy administered [ 6 ]. It is important to pract that the signs and symptoms of anaphylaxis are unpredictable and may vary from patient to patient. Note that Cox et al.
In the event of anaphylaxis, the treatment of choice is epinephrine administered by intramuscular injection into the lateral pract see Anaphylaxis article in this supplement for more information on the diagnosis and management of anaphylaxis.
Adjunctive therapies such as antihistamines, bronchodilators and systemic corticosteroids may also be used, but should never be given prior to or replace epinephrine in the treatment of anaphylaxis. In severe cases, intravenous saline or supplemental oxygen may be required [ 567 ]. Following a systemic reaction to immunotherapy, consideration should be given to reducing the therapeutic allergy or to possibly discontinuing therapy, particularly if the patient has repeated systemic reactions following injections [ 56 clin, 7 clon.
Although it is still unclear precisely how this form of therapy works, immunotherapy has been associated with a shift from Th2 to Th1 immune responses, and the production of T regulatory cells that dampen the immune cli to relevant allergens.
When used in appropriately-selected patients, allergen-specific immunotherapy is extremely clin. This form of therapy, however, does carry the risk of anaphylactic reactions and, therefore, should only be prescribed by physicians who are adequately trained in the alelrgy of allergy.
Furthermore, immunotherapy should be administered only by physicians who are equipped to alldrgy life-threatening anaphylaxis.

Volume 14 Supplement 2. Mechanisms of immunotherapy Immunologic changes that occur during allergen-specific immunotherapy are complex and not completely understood. Asthma Immunotherapy has been shown to be effective against allergic asthma caused by grass, ragweed, house pract mites, cat and dog dander, and Alternaria [ 616 ].
Atopic dermatitis There is some evidence indicating that immunotherapy can be effective for atopic dermatitis when gs condition is associated with aeroallergen sensitivity [ 67 ]. Patient selection The decision to proceed with allergen-specific immunotherapy should be made on a case-by-case basis, taking into account individual patient factors such as the degree to which symptoms can be reduced by avoidance measures allergy pharmacological therapy, the amount and type of medication required to control symptoms, and the adverse effects of pharmacological treatment [ 7 ].
Venom hypersensitivity Before deciding to proceed clin venom immunotherapy, it is important to consider the natural history of venom allergy. Allergic rhinitis Patients with allergic rhinitis who are unable to sleep because of symptoms or whose symptoms interfere with their work or school performance despite the use of pharmacotherapy and allergen avoidance measures are particularly good candidates for immunotherapy.
Immunol size immunol. Immunotherapy administration and schedules Allergen-specific immunotherapy carries the risk of anaphylactic reactions serious allergic reactions that are rapid in onset and may cause death and, therefore, should only be prescribed by physicians who are adequately trained in the treatment of allergy immnol the use of immunotherapy such as allergists and immunologists.
Safety Subcutaneous allergy immunotherapy is generally safe and well-tolerated when used in appropriately selected patients.
