Allergy Type Inhalant Allergens Dr. Sherry Dyer Adult and Pediatric Allergist & Immunologist
Slide 2-

Inhalant Allergens are substances that are distributed in the atmosphere and contact the nasal or buccal mucosa during our respiration process. Defining Inhalant Allergens
Slide 3-

Inhalant Allergens: Allergic symptoms
Slide 4-

Repetitive sneezing, release of watery fluids, swelling of nose, itching, redness and lacrimation of eyes. The allergic reactions are localized because the symptoms are restricted to face only. Similar symptoms may appear in case of other allergies like ingestant allergy.
Slide 5-

The allergic condition or condition of the body is known as sinusitis (inflammation of sinuses or nasal passage) or hayfever. Types of Hayfever: Seasonal Hayfever or pollinosis Non-seasonal Hayfever or perennial rhinitis Inhalant Allergens: Condition
Slide 6-

SEASONAL HAYFEVER
Slide 7-

SEASONAL HAYFEVER: the allergic symptoms may be develop during certain season (months) of the year. This condition is also known as pollinosis because it is related with the release of pollen grains from certain plants. Types of seasons on the basis of pollen grains There are three pollen seasons
Slide 8-

The tree season, in spring which extends from feb. to june. The grasses season, after spring or early summer from april to Aug. The ragweed season in late summer from Aug. to mid Oct. Thus the season in which allergic symptoms occur can be identified the types of pollens grains responsible for the allergy.
Slide 9-

Composition of Pollen Grains Pollen grains can be distinguished and identified easily due to their heterogeneous nature. They may be oval, round, annular, square or rectangular in shape. The outer surface of pollen grains is called “exine” while the inner surface is “intine”. Due to shape and surface appearance of exine, the type of specific pollen grains may be identified.
Slide 10-

The pollen grains may be spread through wind or insects. So the pollens liberated through the anemophilous plants are called atmospheric pollens. These are wind pollinated pollens e.g. pollens of tree such as oak and walnut, pollens of grasses bermuda and timothy, pollens of weeds such as ragweed and plantain. The pollens liberated through entomophilous plants (insects pollinated) are called insect pollinated pollens e.g. pollens of clover, hollyhock and honeysuckle etc.
Slide 11-

Non-seasonal Hayfever
Slide 12-

In case of non seasonal hay fever the allergic symptoms may be developed through out the year with out regularity. It is caused by inhalant allergens other than pollen grains like fungus spore, dust etc. it is also called perennial rhinitis The condition may be for a few days, then disappear and reaper after few days or month or some time it is not regular.
Slide 13-

Causes of Non-seasonal Hay fever It is due to inhalant allergens at the place of living or work. These allergens are: Cotton pillow cases: in home cotton may cause allergy to hypersensitive person. Odor and perfumes: cosmetics contain volatile oils which are inhaled and cause Hay fever. Animal Epidermis or Dander: the epithelial scales called dandra of pet animals (cats, dogs) also cause allergy or Hay fever.
Slide 14-

4. Castor beans: the castor oil seeds contains allergens in the oil cake which cause severe allergy to the person in industry (use castor beans). 5. Fungus spores: the spores are produce by the fungi and distribute in air and cause allergy when inhaled. 7. Dust: it is mixture of different pollens, mold spores, cotton, animal dander, and several other substances. All these substances produce non-seasonal Hay fever. The test for dust allergy is difficult then other tests of allergy.
Slide 15-

The diagnosis of inhalant allergy can be made by prick skin testing or quantitative serum IgE levels against specific inhalant allergens. Prolonged avoidance of house dust mites in eczema patients known to be allergic to dust mites has been reported to result in improvement of their skin disease. Inhalant Allergens: Diagnosis
Slide 16-

Avoidance measures of inhalant allergens include use of house dust mite-proof encasings on pillows, mattresses, and box springs; washing bedding in hot water weekly; removing bedroom carpeting; and decreasing indoor humidity levels. Inhalant Allergens: Avoidance
