Allergic Rhinitis (Nasal Allergies, Hay Fever)

Allergic rhinitis, commonly known as hay fever, is the most common allergic disorder affecting approximately 20% to 25% of the population. The most frequent symptoms are nasal congestion, itchy runny nose, itchy runny eyes, and fits of sneezing. Other frequently accompanying symptoms are headache around the eye area, drainage in the throat, fatigue, and lack of energy. There can also be intense itching of the throat and deep in the ears. The term hay fever is really a misnomer in that it is rarely due to hay, and there is no fever associated with it even though patients feel feverish as the result of the effects of histamine on the blood vessels causing them to dilate and feel warm.

Allergic respiratory symptoms are a result of histamine release along with other chemicals that are either preformed or formed in allergy cells as a result of an antigen antibody interaction.

The job of the allergist is to determine whether the above symptoms are due to allergies or not. Allergic rhinitis is typically classified as seasonal (intermittent) or perennial (persistent), or both. Frequent triggers of true hay fever symptoms include the pollens from grass, tree, and weeds, house dust mite, mold spores, and animal dander. If the above described symptoms are triggered by cleaning one’s home, playing with pets, mowing the grass, etc., then there is high likelihood that symptoms are due to allergies. If your doctor cannot make a correlation of your symptoms with the above triggers, then you need to start thinking outside the allergy box.

The correct diagnostic term for nasal symptoms not due to allergies is non-allergic or vasomotor rhinitis. We don’t understand the mechanism of this condition totally. As the name applies, it is not on an allergic basis, that is to say an antigen antibody interaction. Triggers of non-allergic rhinitis include irritants such as tobacco smoke, chemical odors, cold air, strong perfumes, etc.

Other conditions to consider in people with symptoms of a stuffy nose are hypothyroidism (low thyroid), nasal polyps, tumors (cancer), foreign bodies, infection, and deviated nasal septum. There is also another condition that goes by the acronym N.A.R.E.S. which stands for nonallergic rhinitis with eosinophilia. This means that a person can have all of the symptoms of allergies but are skin test negative, and yet paradoxically have an abundance of allergy cells called eosinophils in their nasal mucus. This condition responds nicely to intranasal steroid sprays.

The nose is the center of the universe to an allergist. If a person does not describe classic nasal symptoms, and for instance only complains that ears or eyes bother them, then the likelihood of symptoms being due to allergies is lessened.

Better Identification of Sesame in Food Packaging Needed to Avoid Anaphylaxis

Study shows more than 50% of products did not declare sesame on the label

In 2021, the US Congress passed the Food Allergy Safety, Treatment, Education & Research Act which, among other things, added sesame to the list of allergens which are mandatory for inclusion on food labels by 2023. A new study in Annals of Allergy, Asthma and Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI), found that among those who self-reported an allergic reaction to sesame, more than 56% of products which contained sesame did not declare sesame on the label.

“Sesame is the ninth most common childhood food allergy in the US, yet many people don’t recognize it on food labels, or it’s missing entirely,” says allergist Katie Kennedy, MD, ACAAI member and senior author on the paper. “What we discovered in our study was that amongst those who reported events related to accidental ingestion of sesame, many reported they didn’t know that words such as ‘tahini’ meant sesame. Because the word ‘sesame’ is often not used on labels, accidents happen at a greater rate.”

The study examined 379 self-reported events related to sesame involving 327 individuals with 360 distinct adverse clinical reactions. 19 events involved a sesame labeling issue that did not result in a clinical reaction. Most of the reports (85%) were from parents providing information on events with their children.

“About 48% of the allergic reactions required hospitalizations or an emergency room visit,” says allergist Kim Nguyen, MD, ACAAI member and co-author of the paper. “Most of the events (63%) occurred at home; about 11% of events occurred at a restaurant, 5% at a friend’s house and 4% of events occurred at school. The most common reason for reporting an event was the occurrence of an allergic reaction following ingestion (99%) as opposed to contact-only exposure.”

“Some of the reports were due to products declared as containing ‘spices’ or ‘natural flavors’ and required consumers to call the company or manufacturer to clarify the ingredients,” says Dr. Kennedy. One of the reported events occurred in a child with a known sesame allergy, and she had eaten meatloaf made with breadcrumbs. The parents later learned that the “spices” labeled on the breadcrumbs contained sesame.

The authors conclude that clear and specific product labeling for sesame is crucial for the prevention of adverse reactions, especially anaphylaxis, in food-allergic people.
