Utah Spring Brings Flying Insect Sting Allergies

Spring has finally arrived in Utah! Spring weather means gardening, beautiful flowers, and flying insects of the stinging variety! Honey bees start leaving their hives and looking for pollen and nectar at about 54 degrees Fahrenheit.   Wasps, hornets, and yellow jackets may become active between 45-50 degrees Fahrenheit.   You may have noticed they are already out this spring looking for victims!

Each year in the U.S. as many as 225,000 people are seen in the emergency room for flying insect stings and up to 100 people die as the result of insect sting anaphylaxis.  It is possible that the number of deaths from insect stings is significantly underestimated, since many of the deaths may be falsely attributed to heart attacks or other causes if the insect sting wasn’t observed.

Are Flying Insects Aggressive?

At Intermountain Allergy and Asthma, I see many patients that come in for evaluation after a “bee sting”.  However, of all the possible insects that sting, honey bees are probably the least likely to cause problems.  Bees usually ignore nearby people unless the person is close to their hive.  You may need to intentionally annoy a bee in your garden in order for it to pay any attention to you.  Wasps, hornets, and especially yellow jackets are a different matter.  They tend to be much more aggressive than honey bees, and will sometimes go out of their way to sting – even when the person poses no threat to the insect or to their nest.

Are Flying Insect Stings Dangerous?

Most single insect stings, while painful, are not at all dangerous.  A fairly large area of swelling, redness, and itching is common and does not indicate that the person has a significant “allergy” to the insect.  Even a very large local reaction (i.e., sting on the finger with swelling to the elbow) may be nothing but a giant nuisance.

However, reactions distant from the site of the sting can indicate a much more severe problem and need to be evaluated.  These symptoms are:

  • Swelling in the throat
  • Chest tightness
  • Head-to-toe hives
  • Significant stomach or intestinal problems

A particularly concerning symptom after an insect sting is light headedness, dizziness, or loss of consciousness.  These symptoms indicate a dangerous, potentially life-threatening, reaction to the sting.

What Should I Do If I Am Stung By a Flying Insect?

Anyone with a potentially dangerous insect sting reaction should be evaluated by an allergist, and should carry an epinephrine injector when outside.   These people can be tested to determine what the actual stinging insect culprit was and then can be desensitized to the venom.  The desensitization process can be a bit of a commitment in time, but it almost always works very well.  Venom desensitizing is one of the most effective things that allergists do.

Milder stings can be treated with cool or cold compresses, hydro-cortisone cream, and oral antihistamines for itch.  Definitely check for an embedded stinger (much more common with bee stings than other insects) and remove it before doing anything else.

How Can I Avoid Flying Insect Stings?

All people with any level of insect sensitivity should try to avoid getting stung in the first place – but this can be a challenge.  Insect repellents don’t seem to help much.  Some people feel that wearing brightly colored clothing attracts flying insects, but not all agree.

Something that does seem to help includes simply staying indoors if there are obvious numbers of insects flying about (but of course that’s not a lot of fun on a nice summer day).  Also, be careful around garbage cans or garbage piles where food has been thrown away and be very cautious drinking sugared or flavored drinks in the summer.  Proteins and sugar can and do attract the little critters.

Enjoy the spring and upcoming summer, but stay alert and “bee vigilant” for stinging insects. If you want to prepare for potential allergic reactions to flying insect stings, make an appointment to see your allergist.

Asthma Season: 4 Steps to Improve Asthma Control

The peak time for asthma symptoms in northern Utah is usually late December thru mid-February.  That’s because three things in winter can worsen asthma:

1. Cold, dry air

2. Poor air quality (an inversion)

3. Viral infections

Since we have an abundance of these three things in Utah during the winter, right now tends to be the worst time of year for asthma.

If you have asthma, there are four things that you should be doing to keep asthma symptoms under control and potentially prevent asthma attacks:

Asthma Control Tip 1: Exercise indoors. I know, I know – running or walking on a treadmill is not nearly as enjoyable as running or walking outside.  However, aerobic exercise in the cold, winter air frequently brings on exercise-induced asthma in those who are at all susceptible to it.  This applies even more so if we have a winter inversion in place!  This last summer, I saw many patients who were having breathing problems because of the smoke in the air.  As bad as the smoke from forest fires was or can be, the trapped car exhaust and other pollutants in an inversion is usually worse.  Your lungs will thank you if you get a membership at the local gym and exercise inside until after Valentine’s Day. 

Asthma Control Tip 2: Make sure that you are taking any regular, preventive asthma medicines daily.  The best medicines for asthma are the daily, preventive ones. They all take a while to ‘kick in’ and have full effect.  Preventative asthma medications can eventually help if you want to wait and start using them daily at the first sign of problems, but they work best if you are already using them consistently before problems arise.  If your asthma prescriptions need refilling – now is the time to see your physician and get new ones.  If you are one of the ‘lucky’ patients with asthma who usually don’t have problems in the winter, at least make sure you have your asthma medications on hand – even if you aren’t using them regularly.  This includes the fast acting ‘rescue’ medicine albuterol.

Asthma Control Tip 3: See your doctor.  If it has been a while since you’ve seen your asthma doctor and had a physical exam and spirometry (pulmonary function tests) done, make an appointment. Many people with asthma are unaware of just how bad their asthma is until things get really bad.  If your asthma gets worse gradually, you may not notice that you’re doing worse, and what should be bothering you can feel like ‘normal’.  This is a very common problem in patients with asthma.  Being worse and unaware at the same time is more likely in the winter.  So, if it’s been a while since you were seen, call your asthma doctor and make an appointment.  Call today – right now!

Asthma Control Tip 4: Buy a condo in Hawaii and live there from December thru February!  Aloha! This way you get to experience a little snow here at the end of the year, and then come back just as the trees and flowers are starting to bloom.  Perfect.  Just in time to be seen for your spring allergies…..

Allergy Myths 101: Animal Allergies

There are many old wives tales or popular myths about how a person can treat their allergies.  Here at Intermountain Allergy and Asthma, we have heard them all!  As a way to help dispel allergy myths, we’ve invited Dr. Harris to share a few his thoughts in our “Allergy Myths 101” blog posts.

Two popular animal allergy myths that we hear frequently are:

  1. “The new dog couldn’t be causing my current problems because it doesn’t shed”
  2. “I grew up with animals, so I won’t be allergic to them now”

Animal allergies are a significant part of what the typical allergist deals with on a daily basis.  Here are some facts about animal allergies and suggestions to help keep symptoms under control.

Animal Allergy Fact 1: Shedding – the vast majority of the time, the animal allergens that cause problems are from the dander (tiny skin particles or flakes – think dandruff in humans), or in the animal’s saliva.  The hair or fur has little or nothing to do with it.  It may be true that a long haired cat or dog could ‘hold – on’ to more dander in the fur than a short haired animal, but whether the fur stays on the pet or is shed doesn’t matter.  All furry/haired pets have dander because they all have skin.

Animal Allergy Fact 2: Pet Saliva There are proteins in pet saliva that can cause allergies.  Some people first know that they are allergic to dogs when they get hives (welts) after being licked by the animal.  Also, cats groom themselves by licking their fur.  When you pet a cat, then rub your eyes ……  cat ‘spit’ in the eye.  Yech! 

Animal Allergy Fact 3: Exposure to animals in the past:  People develop allergies to new things all the time — including animals, plants, and foods — that they weren’t sensitive to in the past.   Tolerating pets in the past doesn’t mean that you are ‘immune’ now.

More importantly, studies have shown that some people can develop a modest amount of clinical tolerance to an animal that they are around all the time.  The allergy skin tests are still positive, but the patient’s symptoms are subdued somewhat.  In many other cases, patients become accustomed to their allergy symptoms and just ignore them, even though they are as bad as ever.  These patients can then be miserable if they leave home for a while (school, marriage, work, world travel), and then return home, or if they decide to get a new pet after years of having none.  

Animal Allergy Solutions

There are some things you can do to decrease an animal’s potential to cause allergies:  Studies have shown that frequent washing, or rinsing an animal can, in some cases, lessen the dander that is deposited around the house.  Also, keeping an indoor animal out of the bedroom, off of the bed and off any fabric-covered furniture could help as well.

Measures that can actually decrease animal allergy problems:

  • Keep furry or feathered pets outside 24/7 when conditions allow (Nobody wants to do this!)
  • If indoors, keep pets off the beds and furniture
  • Wash/rinse pets weekly
  • Get a small animal. Toy poodles should produce less dander than Great Danes
  • Keep the animal’s pelt in good condition. Treat any eczema
  • Use a HEPA air filter in your personal room – or just use good furnace filters and change them frequently (less expensive and probably just as effective)

Animal fact: Cat dander can remain suspended in the air for long periods of time after the cat has left the room.  Cat allergic people can often tell that a cat lives in a home without ever seeing the pet.

Allergy Myths 101: Iodine Allergy

There are many old wives tales or popular myths about how a person can treat their allergies. Here at Intermountain Allergy and Asthma, we have heard them all! As a way to help dispel allergy myths, we’ve invited Dr. Harris to share a few his thoughts in our “Allergy Myths 101” blog posts. 

Here is a popular allergy myth: There are cross-reactions between seafood and iodinated contrast (x-ray contrast dye) caused by “Iodine allergy”. 

What is Iodinated Contrast?

“Iodinated contrast is a form of intravenous radiocontrast (radiographic dye) containing iodine, which enhances the visibility of vascular structures and organs during radiographic procedures. Some pathologies, such as cancer, have particularly improved visibility with iodinated contrast” – Wikipedia.

It is true that some people have allergy-like reactions if they are given iodinated contrast dye during an x-ray procedure, and of course there are many people that have life-threatening allergic reactions after eating fish or shellfish.  However, the truth is that there is no connection between these two types of reactions and no ‘allergy’ relationship at all between seafood and radiologic contrast dyes.

I suspect that this allergy myth got started because radiology dyes and seawater/ seafood both contain iodine.

It isn’t clear why some people react when they are given iodinated contrast dyes, but we do know that it isn’t a true “allergy” to the dye (or to iodine) in the vast majority of cases.  It may be that the iodinated contrast dyes can affect the osmolality (the balance between water and electrolytes) in allergy cells and thus cause the cells to release their active contents.

During a true allergic reaction (such as with a fish or shrimp sensitivity), the immune system is involved and ‘allergic’ antibodies recognize a substance that we are sensitive to, and they (the antibodies) cause the release of active chemicals.  The immune system isn’t involved in most iodinated contrast dye reactions.  The reactions look the same, but take place for very different reasons.

What about people who have terrible reactions to seafood, and then get hives during an x-ray when iodinated contrast was used?

Those people do exist, but that is probably an example of someone who has two common problems at the same time – purely coincidental.  Someone who is allergic to fish is not at dramatically greater risk than anyone else to have a reaction during an x-ray procedure.  Someone who has a reaction to contrast dyes has about the same risk as everyone else to develop a seafood allergy.

Neither a reaction to contrast dyes nor a seafood allergy will cause any problems when consuming iodinated salt in food.

A Tip from Dr. Harris

By the way – We all need a little iodine in our diet for proper thyroid function.
