Patient Handbook Questions How do we treat allergic diseases?
- Avoid the allergen(s) - The most direct and effective treatment is
avoidance of the offending allergen or allergens. Although many
allergens, cannot be completely avoided, even a decreased exposure
may be helpful. Furthermore, avoidance of one allergen may increase
tolerance of other, less easily avoided allergens.
- Medication - A variety of specific and effective medication is now
available. When taken in proper dosage according to a specific
schedule, these medications offer relief to a large number of
allergic patients.
- Specific Immunotherapy (allergy shots,
desensitization): The only treatment which modifies the underlying
allergic inflammatory response and can alter the natural history of
allergy. Immunotherapy may improve allergy sx as well as induce a
tolerance to the specific allergens. This tolerance persists even after
immunotherapy is discontinued. Immunotherapy is considered when
avoidance measures and medications do not provide adequate relief.
| What is involved in an Allergy Evaluation?We will conduct a thorough interview to examine your history of symptoms and conditions. After the interview the visit may include skin testing to evaluate for specific allergens that may be relevant to you. If you have breathing problems we may conduct a specialized lung function test called spirometry. We will then discuss these findings and outline with you a plan to address your condition and concerns. | How do allergens cause allergic symptoms?Allergic inpiduals have a genetic predilection to develop an allergic
inflammatory response on exposure to specific allergens in their
environment or diet. This includes production of allergic antibody
(called immunoglobin E, or IgE). Subsequent exposure to the same
allergen results in binding of the allergen with the IgE antibody
found on cells in the skin, eyes, nose, sinuses, lungs and gut. This
triggers release of chemicals called mediators, such as histamine, from
these cells within the body. These mediators then cause the allergic
symptoms seen in allergic inpiduals. With ongoing stimulation a
chronic inflammation occurs.
| What can cause or aggravate asthma and allergic conditions?
- Airborne (inhalant) allergens
- Pollens
- Animal danders
- Molds
- Dust Mites
- Infection usually viral or the "common cold"
- Exercise
- Non-specific irritants
- Cold air, tobacco smoke, strong odors or fumes, dust, newsprint
- Medications
- Insect stings
- Foods
| What diseases and conditions may be caused or aggravated by Allergy? Asthma or asthmatic bronchitis - wheezing and coughing, shortness of breath, tight chest Allergic rhinitis or hayfever sneezing, itching of eyes and nose, nasal congestion Urticaria (hives) and Angioedema (swelling) Eczema Intestinal allergy - diarrhea, vomiting, or cramps from foods Recurrent respiratory infections, such as recurrent ear infections and sinusitis Sinus headaches Recurrent pneumonia or bronchitis Insect sting reactions Drug allergies Food allergies Generalized allergic reactions (anaphylaxis)
| Why an Allergist?If you have an allergic condition, it means that your immune system
responds to certain substances or situations with an allergic
inflammatory response rather than the normal response seen in the
population without allergy. Allergic symptoms may result from exposure
to pollens, animal danders, insect stings, foods, drugs, as well as
other allergens. This response may result in conditions affecting your
eyes, nose, sinuses, skin, and lungs. An Allergist is uniquely trained
to evaluate and treat both the underlying conditions and identify the
triggers aggravating or causing them.
|
General Should immunization be any different for the allergic child?Smallpox vaccination is no longer recommended. It did cause serious
problems in some children with eczema. Measles, mumps, and rubella
vaccines are grown in chicken tissue, and were avoided in egg
sensitive inpiduals. Now we realize that the amount of egg in these
vaccines is to small to produce a reaction and can be given to
inpiduals who are egg-sensitive. Influenza vaccines, and several
others are grown on egg protein and should not be given to inpiduals
who are highly sensitive to egg. Please consult your physician before
administration of any of these vaccines.
| Should exercise be avoided if it produces or aggravates wheezing or coughing?No. Many people with asthma have some wheezing with exercise. The
amount of difficulty varies with the inpidual and the duration of
exercise. This "exercise-induced bronchospasm," is generally
prevented by the use of medication before anticipated exercise.
Conditioning may also play some role. Specific medicines for this
problem should be reviewed with us to avoid unnecessary restriction
of physical activity.
| Are there any medications which make allergy problems worse?"Beta-blocking" agents, such as those used to control high blood
pressure, can aggravate asthma, and potentiate allergic reactions.
Please tell us all the medications you are taking so that we can be
certain there are no issues.
| Should aspirin be avoided by people with allergies?Aspirin can cause reactions in some people, including asthmas, hives,
and nasal congestion. Aspirin should be avoided if there is any
suspicion that symptoms are aggravated by this medication. Many
aspirin substitutes (e.g., ibuprofen) can cause similar reactions,
and should also be avoided in aspirin-sensitive individuals.
| Why do such things as perfumes, strong odors, and aerosol sprays seem to cause "allergic" symptoms"Most people with allergies have unusually sensitive airways. Factors
that may cause only mild irritation in non-allergic people can cause
a great deal of aggravation and discomfort in those with allergies,
and can actually reproduce their allergic symptoms. Avoidance of
these irritants is the best treatment, but good control of the
underlying allergy may improve tolerance.
| Do people outgrow their allergies?The allergic diseases, especially in children, tend to eventually
become more easily controlled, or even seem to be "outgrown" or
dormant. This may take years, however, so that allergy treatment may
be necessary for prolonged periods. Asthma may occur in childhood,
resolve, then recur as an older adult.
| Are Allergies inherited?The allergic tendency is inherited but the mechanism is not as yet
well-defined. The stronger the family history of allergy, the more
likely it will be that other family members will be allergic.
|
Treatment of Allergic Disease Will a humidifier help?Humidification of the air, especially in the winter, will sometimes
help the allergic patient. However, some patients are made worse by
humidification if excessive, particularly those who are mold or mite
sensitive. Ideal humidity for respiration is 25-50%
| Will a fan help my allergy?Fans potentially make respiratory allergies worse. Anything which
circulates air and allergy particles without filtering tends to make
allergy sufferers have more trouble. This same principle applies to
riding around in open cars in pollen season, walking in fields or
wood on dry, windy days, etc.
|
Allergy Shots How effective are allergy injections?The amount of relief depends in part upon the disease being treated, the age of the patient, and the allergen involved. Most patients do derive significant relief from their symptoms and some become completely free of symptoms. Unfortunately, a few patients derive no benefit and other means of therapy must be found. | Are there any side effects of allergy immunotherapy?Since the shots contain materials to which the patients is allergic, it
is possible to produce allergic symptoms with the injections. Many
patients experience short term itching or swelling at the injection
site. Taking an antihistamine on the day of the injection can
minimize this reaction. Rarely hives, trouble breathing, or a
generalized allergic reaction may occur. A reaction is more common if
the injection is given in a setting of active asthma symptoms. Always
report any breathing difficulties before receiving allergy
immunotherapy. A 30 minute observation period following an allergy
injection is necessary so that in the unlikely event of a reaction it
can be treated promptly.
| How long must the shots be continued?This varies with the allergy being treated and the response of the
patient. In general, patients require injections at regular intervals
for three to five years. This will vary with the allergies being
treated, and the response of the patient.
| Must the injections be given regularly?Since development of tolerance is a slow process, and since very low
doses of the allergenic substances must be used at the start, the
injections should be given at the prescribed intervals. If injections
are given irregularly, control of symptoms may be reduced or delayed,
and risk of allergic reactions to the injections is increased.
| How often must injections be given?In general, allergy shots are given at intervals which can be as often
as twice a week, to as little as once a month. Most schedules require
injections once or twice a week at the start, until the desired
maintenance dose is achieved, then extending to monthly for the
duration of therapy.
| What is the allergy shot?Allergy injections contain small amounts of the substances (allergens)
to which the particular patients is allergic. Allergy injections may
be prescribed for stinging insects, pollens, mites, molds and animal
danders. Food allergy cannot be treated with allergy immunotherapy.
| Does it "cure" the allergy?No, but a tolerance is induced which can be long lasting, even after the injections are discontinued.
| What is allergy immunotherapy?A series of injections to the allergens to which the patient is
allergic, a tolerance to these allergens is gradually build up so
that exposure to the allergen can occur without developing the same
degree of allergic symptoms.
|
Skin Testing How accurate is skin testing?In general, skin test results correlate very well with clinical
sensitivity. As is true in all of medicine, however, there are some
patients who do not follow the rule, and correlation with the
clinical history is, therefore, a very important part of allergy
evaluation.
| How is skin testing done?In this office, two methods are generally used. A majority of tests are
done by "prick" method. Drops of the skin test material are applied
in rows across the back as tiny pricks are made through each drop,
pressing the allergen into the skin. Results are usually read in 10
to 20 minutes. Also, some "intradermal" tests are may done. These
involve a small injection into the superficial layers of the skin of
the arm. "Patch" tests are used to identify materials causing skin
reactions on contact. Small amounts of these materials or gauze
patches are taped on the skin and left for 48 to 72 hours before
being read.
| What is "skin testing"?Skin testing is performed to detect the presence of allergic antibody
to an allergen by introducing the allergen to the allergy cells in
the area of the back or arm. If allergic antibody is present, a small
wheal and flare (hive) will occur at the skin test site.
|
Specific Allergens UrticariaUrticaria (hives) are itchy welts which can occur anywhere on the
skin. Acute hives can be due to an allergic reaction to any of a
variety of agents (foods, infections, drugs, insect stings, allergy
injections, etc.). They may also be of non-allergic origin.
Hives can also become a more chronic problem and often are not due
to allergy. An exact cause may remain undetermined in spite of
extensive investigations. Even then, it is usually possible to
control symptoms with medications.
| EczemaThere are allergic inflammatory cells which are permanent residents
in the skin, and this leads to the chronic dry itchy red skin seen in
eczema. Routine treatment to minimize further inflammation is
necessary to control the symptoms.
Swimming and bathing are useful to reduce the bacterial burden found
in eczematous skin. However this does tend to dry out the skin.
Therefore bathing should be followed immediately by lubrication.
Creams or ointment are preferable to lotions. Children's faces may be
irritated by wiping with a damp cloth after meals. To avoid this,
vaseline can be applied to the child's face before meals. The food
can then be easily removed after meals without using soap and water.
Overheating and sweating can cause itching. Clothing should be
selected which will not cause overheating. For the same reason, nylon
leotards and sneakers or rubber packs should not be worn for long
intervals. Wool is very irritating and should not be worn next to the
skin. Cotton or soft corduroy are good materials to select.
Skin testing may reveal food and other sensitivities which
contribute to the inflammation underlying eczema. Topical steroid
creams or ointments, and some non steroidal anti-inflammatory agents
(elidel, protopic) used on the skin help control the eczema by
decreasing inflammation and controlling infection.
There is no question that much effort and continuing care are
required to help the patient with eczema, but the results can be
gratifying and long-lasting.
| Stinging InsectsThe venom of yellow jackets, hornets, honeybees, and wasps is a very
potent allergen and can cause serious allergic reactions in
sensitized inpiduals. Inpiduals who have had an allergic reaction to
a sting should be evaluated by an allergist for consideration of
allergy testing and immunotherapy. Immunotherapy for stinging insects
is highly successful in preventing serious allergic reaction on
subsequent stings.
| Pets in the homeIndoor warm blooded pets are frequent allergens. Efforts to reduce
dander levels while the pet remains in the home are uniformly
unsuccessful. Many products are marketed with claims they will help a
patients allergies; but the only proven effective means to reduce
allergen levels below those which trigger allergic inflammatory
responses is to remove the animal from the home environment. Preventing
the animal from entering the bedroom area, use of HEPA filters,
removing carpeting, and "mite control" measures may be of some
limited benefit.
| MoldsMolds are fungi. They produce seeds, or spores, which are even
smaller than pollen and are found in the air in large numbers at
certain times of the year. For most inpiduals outdoor molds are the
primary source of mold problems.
Outdoors they are abundant in soil, grass, dead leaves, haystacks,
barns, and stables. Indoors, they are prevalent in areas with
moisture. They are responsible for the familiar musty smell
noticeable in such places. Areas of visible mold or areas with
flooding are the most problematic.
It is quite difficult to eliminate molds from the home environment.
Special attention to ventilation and drainage may help decrease
indoor molds.
| Dust MitesDust mites are a major part of household dust in most homes in our
climate. They live on human dander and are therefore found largely in
areas where dander accumulates. This includes bedding (mattresses,
pillows, blankets, and carpets in bedrooms). It is very important
therefore to cover mattresses, and pillows with dust proof, air tight
encasings. These covers should be cleaned with a damp sponge with
each bedding change. All bedding should be laundered in hot (rather
than warm or cold) water to remove dust mites. Comforters or quilts
that are not easily laundered are therefore not recommended.
| House DustOrdinary house dust represents one of the most troublesome materials to
which allergic patients are exposed. House dust is made up of many
tiny organic and inorganic particles. These organic particles may
include house dust mites, animal and human danders, pollens, and
molds. Therefore, house dust control is an important part of the
overall treatment of many allergic people. Since a person spends more
time breathing the air of his bedroom than of any other roomin fact
one-half of his time in childhood-the focus centers largely in the
bedroom.

| Primary Medical careWe encourage all our patients to initiate or continue care with a
primary care physician (pediatric, family physician, internist). Your
medical care, including that involving allergic problems, will best
be coordinated in this fashion.
A summary of your allergy evaluation and our specific
recommendations will be sent to your physician. You should therefore,
contact your personal physician for any ongoing care (medications,
prescriptions, etc.) and for treatment of any immediate problems.
| Medications containing antihistaminesMedications containing antihistamines can suppress skin tests
reactions. Antihistamines are present in many cold remedies, allergy
medicines, and motion sickness pills. Most antihistamines must be
stopped at least forty-eight to seventy-two hours prior to skin
testing. Some antidepressants also have anti histamine activity and
may interfere with skin tests. If you cannot go without these
medications, or question whether or not your particular medication
should be stopped, check with your doctor or have them call our
office.
~Common Antihistamine Medications : Discontinue 7 days before skin testing ~Fexofenadine (Allegra Hydroxyzine (Atarax) ~Loratidine (Claritin, Alavert) ~Chlorpheniramine (Chlortrimaton) ~Cetirizine (Zyrtec) ~Diphenhydramine (Benadryl) ~Desloratidine (Clarinex)
ASTHMA MEDICATIONS SHOULD BE CONTINUED Aspirin, prednisone, inhaled steroids, bronchodilators, and most other
medications including allergy shots do not interfere with allergy
test results, and can be continued.
- Unless otherwise stated, allergy patients on injection therapy should be re-evaluated every six to twelve months.
- Allergy solutions for injection therapy will usually be mailed
directly to your physicians office. The solution then should be brought
to your local physician for administration. Dosage schedules and
instructions are included with the solutions.
