John Shea, MD

Looking for front office employee for fast paced ENT office.

The 'gold standard' for evaluation and treatment of delayed food allergies has been elimination diets.
Diets are difficult, time consuming, and ineffective. They do not alter the immune response to foods.
The Allertol Method is simple, safe, and effective for testing and treating delayed food allergies.

Allertol can save money with less need for decongestants and nasal sprays, nasal strips and doctor trips, and reduces the need for sinus surgeries.

Multiple body systems can be affected by delayed food allergies producing multiple symptoms including nighttime nasal blockage with snoring, restless sleep and fatigue. Chronic throat clearing and nagging cough are common. Shortness of breath sensations and a lump in the throat sensations can cause anxiety. Eczema, rashes and skin itching can occur.

Migraine and common headache are common, especially menstrual migraine.

Meniere's symptoms of intermittent ear fullness, noise sensitivity, tinnitus and dizziness have been studied, documenting relief using the Allertol Method.

Delayed food allergies can be responsible for GERD, abdominal pain and bloating, IBS-Diarrhea, Eosinophilic Esophagitis (EoE) with trouble swallowing and itching of the middle of the upper back.

WHAT?
Allertol is a proven and patented revolutionary solution for T cell mediated delayed food allergies.

Allertol sublingual drops have FDA approved food allergy extracts, glycerin and water.

HOW?
The Allertol Method utilizes sublingual food drop tests to identify guilty food proteins. These food allergens are then placed in an allergy drop solution for sublingual immunotherapy. This provides long term relief of multiple system symptoms.

Airborne allergies, also called inhalant allergies, are typical seasonal allergies or “hayfever” that many suffer from March through June when tree and grass pollens are prevalent, and in the fall when weeds including ragweed are in the air, and November through February in Texas when mountain cedar is prevalent. Usual symptoms consist of nasal blockage, itchy runny nose, and eye itching. Seasonal asthma is less common. These seasonal allergies change with the direction of the wind, usually decrease when indoors and when traveling to another area. Some airborne allergy symptoms can be perennial, from animal dander such as cat, from house dust mites in bedding, and from mold.

The immune system makes an antibody called Immunoglobulin E (IgE), which reacts with airborne allergens. This antibody can be detected with a high level of accuracy in a blood test. Skin testing may not be a reliable test.

Medications such as nasal steroid sprays, antihistamines and oral steroids are temporarily effective, When these medications are needed perennially, all days, all seasons, all year..... the problem is most likely a T cell mediated delayed food allergy, for which allergy shots or airborne allergy drops, as well as medications, are of little help.

ALLERTOL is a portmanteau combining the words “allergen” and “tolerance”: aller + tol.

Allertol is an allergy drop solution inducing immune tolerance.

Fresh from his training program in Galveston, Dr. John P Shea attended a lecture in 1980 presented by the renowned Harvard trained allergist, Dr. Theron Randolph. Presented was the concept of immune reactions to multiple common foods, and the multitude of delayed symptoms that can be produced. He also discussed the oral route for immunotherapy as an alternative to allergy shots. In 1982, Dr. Shea began offering allergy drops to his patients. In 2007, after 25 years of evaluating allergy drops, ALLERTOL was born, providing an allergy drop solution for common delayed food allergies. The ALLERTOL METHOD of sublingual testing and long term immunotherapy using groups of common food favorites resulted in dramatic long term multi-symptom improvement. The delayed food allergy drops dramatically reduced need for allergy medications, clinic visits, and nasal / sinus procedures.

Allergy drops proved to have many advantages, especially safety.

ALLERTOL for delayed food allergy has helped with nasal complaints especially nasal blockage that worsens nocturnally, deep ear, eye and throat itching; headache including migraine, repeated cough, throat clearing, and wheezing; fatigue; skin itching and eczema; Menieres symptoms of intermittent blocked ear, tinnitus, dizziness.

Favorite foods, like Mexican food and pizza, most commonly cause delayed food allergy symptoms.

Testing for delayed food reactions has been difficult in the past. The “gold standard” has been elimination diets and food challenge. There are no available standard blood tests for delayed food allergies. Specialized skin testing by experienced allergy technicians can reveal delayed food allergy culprits by temporary symptom provocation and temporary relief.

Single food skin tests of IgE responses and needless ineffective blood tests of single foods have been replaced by simple, safe and inexpensive sublingual testing of common groups of food favorites.

ALLERTOL is formulated using food allergy extract approved for injection, by the FDA (Food and Drug Administraton).

What Are Allergy Drops?
They are drops of offending allergen, food or airborne, placed under the tongue, creating allergen tolerance.

How Do They Work?
Receptors under the tongue called Langerhans Giant Cells take up and partially digest protein molecules in the allergy drop solution and present them to immune system T cells. These T-regulatory cells induce ALLERgen TOLerance. They do this by training the immune system by a process called “down regulation”. Each time an allergy drop is placed under the tongue, the immune system becomes more tolerant. This results in significant symptom reduction and less need for medications and procedures..

Safe, Painless, Effective, Low Cost, High Compliance
Allergy drops are administered at home, saving time and travel expense. The out of pocket cost is low, especially considering less need for medications and doctor trips. Allergy drop therapy has been safely administered in the U.S. and in Europe. A literature review by Southwestern Medical School in Dallas revealed no severe life-threatening reactions in 15 consecutive years of allergy drop therapy worldwide. Self limiting adverse reactions have been reported in less than 3 in 1000 doses. Studies have shown that the development of asthma is many times less likely to develop in children that receive allergy drop therapy. Because allergy drops are painless, they are an ideal allergy solution for children and infants. Long-term compliance is as high as 95%.

There are, several factors that make allergy drops a viable alternative to shots, as recommended by the World Health Organization and the Cochrane Study Group out of London.

Education
A Texas native who grew up in Fort Worth, Dr. Shea attended Paschal High School, Tarrant County College, and then University of Texas at Arlington, where he graduated with a Bachelor of Science degree. He then attended the University of Texas Medical Branch in Galveston where he finished medical school in 3 years, completed 2 years of general surgery, and 3 years of otolaryngology / head and neck surgery residency. In 1979 became certified by the American Board of Otolaryngology / Head and Neck Surgery after scoring in the top 10 out of 500 on this national board exam. That same year, he started practicing Otolaryngology in Fort Worth. In 1987 he sat for written and oral exams and became a Fellow of the American Board of Otolaryngic Allergy.

Allergies
Personal experience with allergies began with chronic food allergies during infancy, resulting in sinus and middle ear infections. "Hayfever" began in early teens. Then during adult years, multiple chronic food allergies: migraines from pork, gastrointestinal problems from onion, heart irregularities from processed soy, tinnitus from chocolate, etc.

Treatment has ranged from antihistamines, decongestants, steroid sprays, to a series of allergy shots from the Otolaryngology Clinic in Galveston. Eventually, sinus surgery was performed, but continued chronic delayed food allergy problems continued. Persistent nasal congestion and eventually sinus infections returned. Changing the diet was difficult and helped little. Finally, the solution was found: the ALLERTOL METHOD of sublingual testing and treatment of common foods resulted in resolution of nasal congestion, migraines, GI upset and an irregular pulse: bigeminy.

ALLERTOL® was born.

Patents for the method of testing and treating delayed food allergies were awarded in 2014 and 2018.

Delayed immune reactions to food will be described here as delayed food allergies. The reaction usually occur hours after eating or drinking, but can begin to occur before the end of a meal. Watch repeated sneezing in a restaurant for example, or frequent throat clearing / cough. Any food protein ingested can be a culprit; dairy products are common. Food and drink addictions are commonly associated with delayed food allergies.

Unlike acute food allergy, which can result in severe sudden reactions including anaphylaxis requiring emergency treatment, the delayed food allergy results in chronic problems / medications. And unlike the immediate reaction, which is caused by an antibody called IgE, the delayed immune response is caused by cells of the immune system, particularly the T cell. Immediate, severe food allergies can be tested reliably with Immunoglobulin E ( IgE) blood test, but there is not a blood test for delayed food allergies. Studies of T cells are ongoing, and someday there may well be a blood test available that uncovers the food proteins responsible for delayed food allergies.

Delayed food allergies are often “hidden” in the diet, and seldom suspected, as symptoms often occur several hours later. The patient will often state “I can’t be allergic to that; I love it and have it all the time!” The delayed food allergy patient may be allergic to many foods with different and confusing reactions with different delays.

The immediate food allergy patient becomes acutely aware of which food must be avoided, and experiences the same set of severe sudden symptoms. An example is severe asthma within minutes of eating peanut, tree nut, fish or seafood. Allertol is not used for these life-threatening food allergies.

Like allergy shots, allergy drops use FDA approved antigen extracts to create an allergy drop solution for each patient. In the United States, an increasing number of patients have received benefit from allergy drops. In much of Europe, allergy drop therapy is used more often than shots. Like a series of allergy shots, allergy drops are used to gradually build allergen tolerance over several years.

There are, several factors that make allergy drops a viable alternative to shots, as recommended by the World Health Organization and the Cochrane Study Group out of London.

How is testing done?
Sublingual testing is done by simply placing drops of suspected food proteins under the tongue several times a day, and observing symptom changes.

Benefits, Risks, Alternatives
1) Benefits: symptom reduction, limiting need for repeated doctor trips, medications, and procedures. This increases quality of life.

2) Risks: adverse reactions, such as temporary mouth itching and irritation, nasal blockage, headache, gastrointestinal upset, skin itching and dermatitis, and wheezing.

3) Alternatives: continued medical management, nasal procedures, and allergen avoidance by elimination diets.

Procedures to improve nasal symptoms include surgery to remove bone and cartilage from the septum, as well as and destructive procedures such as partial turbinate removal and freezing a nerve behind the nose.

Although eliminating common foods and food favorites is seldom done with any long terms success, you may try to completely omit those foods to which you are addicted several days, and then reintroduce. Note any symptoms. For example, chronic delayed allergy to dairy is common, so if you crave milk or cheese, try giving up all dairy products for 4 days, then re-introduce. Elimination of the offending food protein does not induce allergen tolerance. Even years later when the food is reintroduced, symptoms return.
