Experts report allergy season will worsen each year due to environmental changes.

Allergy season usually begins in March with the start of Spring and can extend to the Fall even leading to new Fall allergies.

Each year we find allergy season starting a few weeks earlier as temperature changes prompt early blooms.

Tree pollens start first in January and then taper off in April.  Grass pollen starts to rise in February and March.   Finally weed pollens join the party by the Spring and extends through the Summer and Fall.

Dr. Jeffrey Demain, Board Certified Allergist and Immunologist reported at the March meeting of the American Academy of Allergy, Asthma and Immunology the following, “We have higher temperatures and expanding levels of carbon dioxide.

“When you look at a pollen grain, there are certain proteins that cause the allergy, they are the allergenic peptides,” he said. “It’s been shown that in rising carbon dioxide, the allergenic peptide of each pollen grain goes up.”

Plants utilize carbon dioxide for respiration as humans use oxygen.  The higher carbon dioxide levels, the higher the pollen counts and proteins in pollens that contribute to allergies.

The increase in storms may contribute to allergy season as well as moisture in the air causes pollen to swell and “explode” into multiple little pollen particles, smaller and easier to breathe in.

Moreover stagnant flood water may cause fungi, mold and spores to grow, also leading to allergies.

The Allergy Capitals Spring 2018 report found many cities are worse off this year than they were in previous seasons. McAllen, TX , Louisville, KY, Jackson, MS, Memphis, TN  and San Antonio, TX ranked in the top 5 in “Most Challenging Places to Live With Spring Allergies.” The copy of the report is below:

Let’s review allergies…..

What are allergies?

 

Allergies are the result of the immune response to a foreign particulate that our body senses.  One could be allergic to pollen, dust, dander, food, insects, mold, metals, transfused blood, grafts, medicine and anything the body senses as a foreign intruder.  Even though these may be individually harmless, a hypersensitivity reaction occurs as a result of their intrusion into the body.  IgE antibodies find the allergen (intruder) and activate mast cells in the tissue and basophils in the blood.  When these cells get activated, they release substances to help protect the body, including histamines, leukotrienes, and cytokines. These help the body attempt to sneeze and cough the allergen out, wall off the antigen, signal more antibodies, or produce tears and nasal secretions to flush it out.

What are symptoms of seasonal allergies?

 

Symptoms of allergies could include any or a combination of the following:

  • Sneezing
  • Coughing
  • Wheezing
  • Runny nose
  • Eye watering
  • Red Eyes
  • Itchy eyes
  • Itchy skin
  • Rash
  • Itchy throat
  • Fatigue
  • Congestion….. to name a few.

How do they differ from a cold?

 

Colds may have very similar symptoms to allergies.  However they are different. The common cold is caused by a virus.  When one gets infected by the virus they may feel malaise, fever, and achy.  This does not occur with allergies. Moreover, nasal secretions from allergies are usually clear.  In a cold, the mucous could be thicker and with color. The same holds true with sputum.  During an allergy the cough may have little to no mucous and if so, be light colored.  Thick mucus could be a sign of an infection. An allergic sore throat will seem more dry and scratchy.  A sore throat from a cold is more uncomfortable and less easy to soothe. Allergies may persist or be cyclical.  Cold symptoms will usually subside after a few days and rarely persist longer than 10 days.

Can allergies lead to a cold?

 

Yes and no.  Allergies should not in and of themselves cause an infection. However they may make one more vulnerable for a virus or bacteria to take over.    Hence a bronchitis, sinus infection, or pneumonia could uncommonly follow an asthma attack.

Are seasonal allergies dangerous?

 

As stated previously, if one is susceptible to colds, an allergic attack could make them vulnerable. Moreover if one suffers from asthma, an allergy attack could incite an asthma attack.  Very rarely would we see a life threatening anaphylaxis to an allergen such as pollen.

How can we prevent and treat allergies?

 

Avoiding, or decreasing exposure to the allergen is key.   We suggest the following:

  1. Be aware of your local weather and pollen counts.  If the weather begins to warm and regional vegetation is blooming, allergy season may be upon you sooner than you know.
  2. Avoid outside pollen from coming into your house.  Avoid the urge to open all the windows during Springtime as wind will bring the pollen in.
  3. Clean your air filters.  Replace air filters frequently and consider using HEPA Filters
  4. Wash off pollen from your hair and clothes before you sit on the couch or jump into bed.
  5. Close your car windows when you park.
  6. “Recirculate” the air in your car
  7. Discuss with your medical provider if you are a candidate for medications such as antihistamines, nasal corticosteroids or leukotriene antagonists.  
  8. If you suffer from respiratory illnesses or a chronic medical condition, discuss with your medical provider if you need to start your allergy medication before allergy season hits. Some of these medications may take a couple of weeks to reach therapeutic levels.

The EpiPen® auto-injector contains epinephrine, used during an emergency to treat severe allergic reactions, or anaphylaxis.

If one is allergic to an insect or food, a severe allergic reaction may ensue upon exposure, in which the immune system releases a flood of chemicals that can cause throat tightness, hives, lip and facial swelling, difficulty breathing, nausea, vomiting, low blood pressure, rapid heart rate, cardiac arrest and possibly death.

Epinephrine stimulates the heart to increase cardiac muscle contractility, cardiac output, subsequently raising the blood pressure. Additionally it relaxes the muscles surrounding the airways, allowing one to breathe easier and take in more oxygen. Moreover it helps to stop the release of additional immune chemicals.

The EpiPen® is manufactured by Mylan. Its cost made headlines when the EpiPen two-pack recently stickered for close to $600. Now generic forms are available costing anywhere from $109-$300 for a dual pack.

The disposable auto-injector, for an adult, delivers 0.3 mg of epinephrine, while the EpiPen Jr., used in pediatric populations, delivers 0.15mg of the medication.  It can be self-administered, through clothing if necessary, into the thigh muscle in one smooth movement once the safety release is removed.

After 0.3 ml is administered during the single adult dose, the EpiPen® unit is discarded.

However many are not aware that 1.7 ml of solution remains within the cartridge.  This could, in theory, be used for an additional 5 doses if in a remote, “wilderness” setting.

Dr. Arthur (Tony) Islas, Fellow of the Academy of Wilderness Medicine, and professor at the University of Nevada, Reno School of Medicine’s Department of Family Medicine, demonstrated how to extract the remaining doses from the autoinjector at the January Nevada Academy of Family Physicians meeting in Lake Tahoe.

Although it's recommended that all users follow the manufacturer’s labels, those trained in emergency and wilderness medicine may take the used cartridge, cut off the top plastic, and extract the syringe with the remaining fluid.

Dr. Islas states the initial 0.3 mg dose of epinephrine lasts for 20 minutes.  For most people this allows plenty of time for emergency responders to come to the site of the victim.  However, in a “wilderness” or remote setting, another dose may need to be administered during a very severe case of anaphylaxis.

PLEASE NOTE MANIPULATION, DESTRUCTION, AND OFF-LABEL USE OF AN EPIPEN CARTRIDGE COULD BE DANGEROUS AND SHOULD ONLY BE PERFORMED BY A TRAINED PROFESSIONAL.

Allergy season may start early this year

Multiple states are reporting “early” allergy seasons.

We still have a month left of winter yet grass is sprouting, leaves are growing and flowers are blooming.  Add warmer than normal temperatures to the mix and this is the perfect recipe for an early allergy season.

Allergy season usually begins with the start of Spring in March.  Yet many may start their symptoms as early as February if they are allergic to what’s blooming.

Tree pollens start first in January and then taper off in April.  Grass pollen starts to rise in February and March.   Finally weed pollens join the party by the Spring and extend through the Summer and Fall.

Allergies to Marijuana on the Rise

In 2015 Dr. Thad Ocampo and Dr. Tonya Rans published a paper looking at cannabis allergies that ranged from eczema to asthma to anaphylaxis.

 

Daily Mail now reports 36 million Americans could be allergic to marijuana, stating 73 percent of the 50 million people who react to pollen also have issues with cannabis – and the figure is rising. This comes as no surprise as marijuana is a plant that carries pollen. Those exposed to second hand cannabis may be at risk as well. In 1971, a 29 year old woman claimed to have smoked marijuana for the first time when she went into a full anaphylactic reaction, being unable to breath.

 

Cannabis sativa is one of the more common strains of cannabis used and its hypersensitivity could cause one to have any of  the following:

 

Cough

 

Sneezing

 

Wheezing

 

Rash

 

Itch

 

Hives

 

Runny eyes, conjunctivitis

 

Difficulty breathing

Cannabis indicia is the other more common strain, whose leaves are wider and may pose allergic risks as well. Dr. Ocampo and Rans also discusses cannabis seed encrusted seafood which caused an anaphylactic reaction in a patient who was not allergic to seafood.

 

EpiPens could provide support for those suffering reactions and may need to be on hand for those who smoke or are exposed to marijuana smoke.

 

Allergic reactions occur when an allergen enters the body and the immune system tries to reject it. This defense mechanism, however, could cause many symptoms, including bronchoconstriction, preventing one from being able to breathe.  EpiPens provide epinephrine opening up the bronchioles and therefore allowing air exchange.
