View products | | | Allergy is a term generally used to describe an adverse reaction to
any substance which the affected individual ingests, inhales, or touches.
Strictly, allergy refers to reactions incited by an abnormal immunological
response to an allergen. Susceptibility has a strong genetic component and
is usually initiated by a high immunoglobulin E response (see
immunity) to substances such as insect venom, egg proteins,
peanuts, and grass pollen. Severe reactions are often termed
anaphylaxis which may be local or systemic. Other immune mechanisms
also contribute to allergic disorders. However adverse reactions to drugs,
diagnostic materials, and other substances often do not involve recognized
immunological mechanisms when the term `hypersensitivity' is preferable.
Adverse reactions may manifest themselves as urticaria wheezing
or difficulty in breathing owing to spasm of the bronchioles,
swollen joints, nausea and headaches. Severe allergic reactions may cause
a person to go into shock. Prevention is the best treatment with
the sensitive individual avoiding the food or other factor such as pollen
known to cause an allergic reaction. This may require extensive testing to
establish the allergen. Sometimes an allergy may be cured by desensitizing
the individual with small doses of the allergen. Severe allergic symptoms
may require treatment with sympathomimetic drugs such as
adrenaline, with antihistamines or with steroids. Expert medical
attention is needed for patients with severe reactions.
Allergies
are responses mounted by the immune system to a particular food, inhalant
(airborne substance), or chemical. In popular terminology, the terms
"allergies" and "sensitivities" are often used to mean
the same thing, although many sensitivities are not true allergies. The
term "sensitivity" is general and may include true allergies,
reactions that do not affect the immune system (and therefore are not
technically allergies), and reactions for which the cause has yet to be
determined.
Some non-allergic types of sensitivity are called
intolerances and may be caused by toxins, enzyme inadequacies, drug-like
chemical reactions, psychological associations, and other mechanisms.1
Examples of well-understood intolerances are lactose intolerance and
phenylketonuria. Environmental sensitivity or intolerance are terms
sometimes used for reactions to chemicals found either indoors or outdoors
in food, water, medications, cosmetics, perfumes, textiles, building
materials, and plastics. Detecting allergies and other sensitivities and
then eliminating or reducing exposure to the sources is often a
time-consuming and challenging task that is difficult to undertake without
the assistance of an expert.
What are the symptoms of
allergies? Common symptoms may include itchy, watery eyes; sneezing;
headache; fatigue; postnasal drip; runny, stuffy, or itchy nose; sore
throat; dark circles under the eyes; an itchy feeling in the mouth or
throat; abdominal pain; diarrhea; and the appearance of an itchy, red skin
rash. Life-threatening allergic reactions-most commonly to peanuts, nuts,
shellfish, and some drugs-are uncommon. When they do occur, initial
symptoms may include trouble breathing and difficulty
swallowing.
Conventional Treatment Options: People with
allergies and sensitivities are typically advised to avoid exposure to
particular allergens, such as tree and grass pollens, dust mites, molds,
specific foods, latex, or environmental and household irritants.
Conventional treatment also includes medications such as antihistamines
and bronchodilators, in addition to weekly allergy shots (desensitization
immunotherapy). Doctors may also recommend that people with severe
allergies wear a medical alert tag and carry an auto-injector syringe of
epinephrine (EpiPen) for use during an attack.
What conditions
are related to allergies? According to J. C. Breneman, M.D., author of
the book Basics of Food Allergy, many health conditions are related to
allergies and have been the subject of independent studies. Even so, any
relationship between the condition and the allergy needs to be considered
with the aid of a doctor.
The following conditions may also be
related to allergies and other sensitivities:
Bed-wetting
(Nocturnal enuresis) If there is no medical cause for bed-wetting,
allergies should be investigated. Several researchers have reported that
allergies appear to be an important cause of bed-wetting.
Cyclic
vomiting syndrome Allergies to foods, especially cows' milk, may
play a role in cyclic vomiting syndrome, a disorder characterized by
repeated unpredictable, explosive and unexplained bouts of vomiting. This
condition affects nearly 2% of school-aged
children.
Gastrointestinal symptoms Vague
gastrointestinal (GI) symptoms (such as abdominal pain, bloating, gas, and
diarrhea) that are not caused by serious disease can sometimes be
triggered by food sensitivities. In one double-blind trial, people with
vague GI problems believed to be caused by dairy were given dairy to see
how their bodies would react. These people were not lactose intolerant.
Various indicators of immunity changed as a result of the dairy challenge,
showing their bodies were reacting to the dairy in an abnormal way.
However, the indicator of a true dairy allergy (milk-specific
immunoglobulin E) was normal in most of these people. This study suggests
that vague GI symptoms unrelated to serious disease can be caused by food
sensitivities that reflect neither lactose intolerance nor true
allergies.
IgA nephropathy (autoimmune kidney disease) In
a small, preliminary trial, people with IgA nephropathy consumed a
hypoallergenic diet (rice, olive oil, turkey, rabbit, lamb, green
vegetables, potatoes, pears, apples, salt, and water) for 14 to 23 weeks.
Laboratory parameters for kidney function improved significantly, and all
participants remained relapse-free while maintaining the
diet.
Multiple Food Protein Intolerance (MFPI) of
infancy Many infants who are intolerant to one food have been found
to also be intolerant to several other food proteins, including soy
formula and extensively hydrolyzed formula. This syndrome has recently
been dubbed Multiple Food Protein Intolerance (MFPI) of infancy. As a
group, these infants tend to have symptoms of severe colic,
gastroesophageal reflux and esophagitis (inflammation of the esophagus due
to irritation by stomach acids from repeated episodes of reflux), or
atopic dermatitis (eczema). As many as 30% of infants may suffer from
these symptoms, but it is not yet clear how many of them may be suffering
from this syndrome.
Multiple chemical
sensitivity Multiple chemical sensitivity, also known as idiopathic
environmental intolerances, is a poorly understood and controversial
chronic disorder in which a person may have a variety of recurring
symptoms believed to be due to reactions to very small amounts of
substances in the environment.106 107 108 Avoidance of these substances,
though often difficult, has been reported to bring at least partial
relief, and psychological counseling has also been reported to be
helpful.
Musculoskeletal pain (including back
pain) Ingestion of allergenic foods has been reported to produce a
variety of musculoskeletal syndromes in susceptible
people.
Nephrotic syndrome Several studies have found a
link between nephrotic syndrome (a kidney disease) and allergies. In one
study nephrotic syndrome patients responded when the allergens were
removed from their diet; however, in another study patients did not
respond.
Leaky gut syndrome Allergy to food has been
associated with increased permeability, or "leakiness," of the
intestine. Some alternative health practitioners believe that this
increased permeability, sometimes referred to as the "leaky gut
syndrome," is an important treatable cause of food allergy. However,
the reverse may also be possible. Allergic reactions in the intestine tend
to cause temporary increases in permeability, which would explain the
apparent connection between the two. More research is needed to better
understand the role of intestinal permeability in the development and
treatment of food allergies.
Dietary changes that may be
helpful: A low-allergen diet, also known as an elimination diet or a
hypoallergenic diet is often recommended to people with suspected food
allergies to find out if avoiding foods that commonly trigger allergies
will provide relief from symptoms. This diet eliminates foods and food
additives considered to be common allergens, such as wheat, dairy, eggs,
corn, soy, citrus fruits, nuts, peanuts, tomatoes, food coloring and
preservatives, coffee, and chocolate. Some popular books offer guidance to
people who want to attempt this type of diet. The low-allergen diet is not
a treatment for people with food allergies, however. Rather, it is a
diagnostic tool used to help discover which foods a person is sensitive
to. It is maintained only until a reaction to a food or foods has been
diagnosed or ruled out. Once food reactions have been identified, only
those foods that are causing a reaction are subsequently avoided; all
other foods that had previously been eaten are once again added to the
diet. While individual recommendations regarding how long a low-allergen
diet should be adhered to vary from five days to three weeks, many
nutritionally oriented doctors believe that a two-week trial is generally
sufficient for the purpose of diagnosing food reactions.
Strict
avoidance of allergenic foods for a period of time (usually months or
years) sometimes results in the foods no longer causing allergic
reactions. Restrictive elimination diets and food reintroduction should be
supervised by a qualified healthcare professional.
Lifestyle
changes that may be helpful: People with inhalant allergies are often
advised to reduce exposure to common household allergens like dust, mold,
and animal dander, in the hope that this will reduce symptoms even if
other, non-household allergens cannot be avoided. Strategies include
removing carpets, frequent cleaning and vacuuming, using special air
filters in the home heating system, choosing allergen-reducing bed and
pillow coverings, and limiting household pets' access to sleeping
areas.
Nutritional supplements that may be helpful:
Probiotics may be important in the control of food allergies because of
their ability to improve digestion, by helping the intestinal tract
control the absorption of food allergens and/or by changing immune system
responses to foods. One group of researchers has reported using probiotics
to successfully treat infants with food allergies in two trials: a
double-blind trial using Lactobacillus GG bacteria in infant formula, and
a preliminary trial giving the same bacteria to nursing mothers.
Probiotics may also be important in non-allergy types of food intolerance
caused by imbalances in the normal intestinal flora.
Thymomodulin
is a special preparation of the thymus gland of calves. In a double-blind
study of allergic children who had successfully completed an elimination
diet, 120 mg per day of thymomodulin prevented allergic skin reactions to
food and lowered blood levels of antibodies associated with those foods.
These results confirmed similar findings in an earlier, controlled
trial.
According to one theory, allergies are triggered by
partially undigested protein. Proteolytic enzymes may reduce allergy
symptoms by further breaking down undigested protein to sizes that are too
small to cause allergic reactions. Preliminary human evidence supports
this theory. Hydrochloric acid secreted by the stomach also helps the
digestion of protein, and preliminary research suggests that some people
with allergies may not produce adequate amounts of stomach acid. However,
no controlled trials have investigated the use of enzyme supplements to
improve digestion as a treatment for food allergies.
Many of the
effects of allergic reactions are caused by the release of histamine,
which is the reason antihistamine medication is often used by allergy
sufferers. Some natural substances, such as vitamin C and flavonoids,
including quercetin, have demonstrated antihistamine effects in test tube,
animal, and other preliminary studies. However, no research has
investigated whether these substances can specifically reduce allergic
reactions in humans.
Are there any side effects or
interactions? Refer to the individual supplement for information about
any side effects or interactions.
Other integrative approaches
that may be helpful: Acupuncture may be helpful in the treatment of
some types of allergy. Studies of mice treated with acupuncture provide
evidence of an anti-allergic effect with results similar to treatment with
corticosteroids (cortisone-like drugs). A preliminary trial found a
significant decrease in allergy symptoms following acupuncture treatment.
It was found that the decline in symptoms coincided with a decline in
laboratory measures of allergy. Relief persisted for two months following
the treatment. Other preliminary trials have also demonstrated positive
results. One controlled trial reported a reduction in allergic complaints
following acupuncture treatment, but the results were not statistically
significant. In the future, controlled trials with larger numbers of
subjects may help to determine conclusively whether allergies can be
successfully treated with acupuncture
therapy.
Provocation-neutralization is a controversial method of
both allergy testing and treatment. Treatment consists of injecting minute
dilutions of foods, inhalants, or (in some cases) chemicals into the lower
layers of the skin. This approach is not the same as traditional
desensitization injections given by medical allergy specialists.
Preliminary and double-blind research suggests treatment of allergies by
provocation-neutralization may be effective, though negative double-blind
research also exists.
Allergy treatment using extracts of allergens
taken orally is another controversial method advocated by some alternative
healthcare practitioners. Most but not all double-blind trials have found
this approach effective for house dust allergy. Preliminary and
double-blind trials have reported success using this method for other
allergies as well.
Treatment of food allergy using very small but
increasing daily doses of actual foods has been reported, and in one
controlled trial 12 of 14 patients successfully completed the program and
could tolerate previously allergenic foods.
All desensitization
programs require the guidance of a healthcare professional. While none of
these approaches has been unequivocally proven, several show promise that
people with allergies may be treatable by means other than simple
avoidance of the offending food or inhalant substance.
What
tests can detect allergies? Several tests or procedures are used by
physicians to detect allergies. Most of these tests remain controversial.
Some clinicians (cited below), however, believe some of these tests can be
effective.
Scratch Testing This form of testing is one
of the most widely used. A patient's skin is scratched with a needle that
contains a portion of the food, inhalant, or chemical that is being
tested. After a period of time, the skin is examined for reactions. If
there is a reaction, it is determined that an allergy exists. Although
this test is accepted by most allergists, scratch testing is subject to a
relatively high incidence of inaccurate results, some tests showing
positive when the person is not truly allergic to the substance (false
positive) and some tests showing negative when an allergy really exists
(false negative).
RAST/MAST/PRIST/ELISA (and other tests that
measure immunoglobulins) The radioallergosorbent test (RAST)
indirectly measures antibodies in the blood that react to specific foods.
It is used by many physicians and has been shown to be a somewhat reliable
indicator of allergies. It does not, however, help diagnose non-allergic
food sensitivities and is therefore associated with a high risk of false
negative readings. In an attempt to avoid this problem, a variety of
modifications have been made to tests related to RAST (such as MAST,
PRIST, and ELISA). Some of these changes may have reduced the risk of
false negative readings somewhat but are likely to have increased the risk
of false positive readings. A number of conditions associated with food
sensitivities, such as migraine headaches and irritable bowel syndrome,
have shown remarkably poor correlation between RAST results and the actual
sensitivities of patients.
Cytotoxic testing The
cytotoxic test views a patient's serum under a microscope to see whether
it is reacting to certain substances. The test is subject to numerous
errors and is not generally considered to be reliable.
Clinical
ecology (provocation-neutralization; end-point titration) This
branch of medicine is considered very controversial. Testing is done using
intra-dermal (under the skin) injections of minute dilutions of foods,
inhalants or (in some cases) chemicals. Based on reactions, additional
dilutions are used. This test not only determines whether an allergy
exists but also operates on the theory that one dilution can trigger a
reaction while another can neutralize a reaction. Preliminary research
suggests this approach may have beneficial effects, A similar method uses
these dilutions under the tongue to test for allergies. Double-blind
research has not found this method effective.
Elimination and
reintroduction The most reliable way to determine a food allergy is
to have the patient eliminate a suspected food from the diet for a period
of time and then reintroduce it later. Once a food is eliminated, the
symptoms it may be causing either improve or resolve, typically after
several days to three weeks. The body then becomes more sensitive to the
food, so when the food is reintroduced, the symptom is more likely to
recur. This tool shows with a high degree of certainty which foods are
problem foods. The testing requires a great deal of patience and, as with
all other forms of allergy testing, is best undertaken with the help of a
physician who can monitor the diet. Reintroduction of an allergenic food
has been reported to lead occasionally to dangerous reactions in some
people with certain conditions, particularly asthma-another reason this
approach should not be attempted without supervision.
Other
tests Bioelectric tests are controversial procedures that attempt
to measure changes in electrical activity at acupuncture points when a
potential allergen is brought into proximity. A preliminary study reported
that the EAV (Electroacupuncture According to Voll) device, also called
the Vega test, identified the same allergens as RAST testing in 70.5
percent of tests. Another preliminary study found the Vega test identified
the same neutralization doses as clinical ecology testing (see above) in
66% of tests. More research is needed to better evaluate these testing
techniques.
