Many pets suffer recurrent skin problems
relating to allergies. Allergic reactions are
caused by overzealous response of the body’s immune system to a
stimulant. When the immune system is exposed to an inhaled
substance, it may produce antibodies directed against that
substance. On repeated exposure, these
antibodies cause the release of chemicals that cause the allergic
symptoms. In people, of inhalant allergies
involve the upper respiratory system and include, watery eyes, runny
nose, sneezing etc. In dogs and cats, the
response to these same allergens tends to cause generalized
itchiness more so than upper respiratory symptoms.
In your pet, the results or inhalant allergy may be any of
the following:
·
Chronic ear infections
·
Chronic itchiness
·
Thickening of the skin
·
Skin pigmentation (blackening)
·
Greasiness of the coat
·
Flakiness of the skin
·
Bad skin odor
·
Sores on the skin
Most often, the symptoms of inhalant allergies
worsen in the spring and summer months as the amount of allergens in the
air increases from all of the flowering plants, grasses and trees.
In our area, the growing season is virtually year round so many
pets seem to suffer all year round with certain times being worse than
others.
How do we diagnose inhalant allergies?
There are two methods to test for inhalant
allergies; intra-dermal skin testing and blood testing.
Intra-dermal skin testing is an involved process that requires
shaving the hair off the side of your pet and injecting 60 or more
potential allergens into the skin to see what kind of response the pet
makes to it. While this technology is the “gold
standard” by which to diagnose this condition, it is cumbersome and
expensive. Recently, advances in blood test
technology have made this type of test much more attractive in helping
us diagnose inhalant allergy. A small sample of
blood collected on an empty stomach will give us results within a week
as to whether or not your pet is allergic and to what allergens he/she
is allergic.
How do we treat inhalant allergies:
Inhalant allergies can be successfully treated by
use of a technique called
desensitization.
In this process, a “vaccine” is created specifically for your pet
that includes minute amounts of each of the offending allergens detected
during the test. We inject small amounts of this
vaccine under the pet’s skin at prescribed intervals so that the body is
continually being exposed to the allergens. After a
time (generally 1-year to 18 months) the body begins to get used to the
allergens and stops making such a big response to them when they come in
through the respiratory tract. .
Desensitization is an on going process. In order to
be successful, it generally has to continue throughout the pet’s life.
Usually, injections are given just once a month after the initial
induction process.
What can we expect from desensitization therapy?
Desensitization is a slow and gradual process.
Before beginning it, we like owners to make a commitment to stick
with the program for at least 18 months before making a judgement on its
efficacy. In most cases, owners report a 75 85%
reduction in symptoms in their pets usually beginning around 10
to 12 months into the therapy. This translates
into a much more comfortable pet, fewer flare-ups of allergy based
problems and less potentially harmful drug therapy needed.
Are there risks involved with desensitization?
The allergy serum created for your pet is a
biologic product. When injected into the pet, there
is a very small (less than 1 in 10,000) chance that your pet could have
an anaphylactic (severe allergic) reaction to the injections.
For this reason, the first 5 injections are generally
administered here at our facility under the supervision of a
veterinarian. Each serum is tested for sterility
prior to being shipped to us. Because there are no
preservatives in the serum, it must be refrigerated and there is a very
small chance of infection associated with the injections.
You will be taught proper technique in handling the serum, which
should minimize this risk.
What do we do to take care of my pet’s skin
problem while desensitization is proceeding?
Once we have made the diagnosis of inhalant
allergy, we will be free to use drugs to give your pet relief. These
drugs typically may include prednisone (a form of
cortisone), antihistamines, medicated shampoos
and conditioners, essential fatty acid
supplementation and hypoallergenic diets.
Once we get the current problem under control, maintaining your
pet’s comfort should be much easier.
What are the costs involved in this Diagnosis and
Therapy?
Allergy testing and treatment has never been more
affordable. Frequently the costs incurred in this treatment are offset
by reduced costs involved with treating the chronic skin problem that
has plagued your pet. Our veterinarians will be
happy to give you an estimate of the cost of testing and treating your
pet.
