Cindy Heller asked:


Most everyone has an idea of what an allergy is. Allergies are so common, in fact, that it seems acceptable to discuss allergy symptoms at a cocktail party with perfect strangers.

An allergy is an abnormal reaction by a person’s immune system to a normally harmless substance. A person without allergies would have no reaction to this substance, but when a person who is allergic encounters the trigger, the body reacts by releasing chemicals which cause allergy symptoms.

In children, allergic disease first occurs as atopic dermatitis (eczema) or food allergies. Children with atopic dermatitis are then at an increased risk of developing allergic rhinitis and asthma; both are more likely to occur in school-age children.

Typically, atopic dermatitis goes away by adulthood, as do many types of food allergies.

Allergic rhinitis and asthma, however, most often start during the adolescent, teenage and young adult years, and are likely to persist throughout a person’s life. The severity of allergic symptoms, however, may wax and wane, and even temporarily disappear during a person’s life.

Atopic Dermatitis

This is typically the first sign of allergies and is seen in 10 to 20% of all children, frequently during infancy. Atopic dermatitis, or eczema, is characterized by itching, with rash formation at the sites of scratching. The rash is typically red and dry, may have small blisters, and can flake and ooze over time.

In infants and very young children, this rash involves the face (especially the cheeks), chest and trunk, back of the scalp and may involve the arms and legs. This distribution reflects where the child is able to scratch, and therefore usually spares the diaper area. The location of the rash changes in older children and adults to classically involve the skin in front of the elbows and behind the knees. Food and environmental allergies have been shown to worsen atopic dermatitis.

Food Allergies

Food allergies can occur at any age. Almost all people with food allergies will have a skin symptom, such as hives, swelling, itching or redness of the skin, as a result of eating the culprit food. These symptoms typically occur within a few minutes of eating the food in question, although they can be delayed up to a couple of hours.

Other symptoms of food allergies can include nausea, vomiting, stomach aches, diarrhea, breathing difficulties (asthma symptoms), runny nose, sneezing, and lightheadedness. In some cases, children can experience a severe allergic reaction, called anaphylaxis, which can be life-threatening.

Nasal Allergies

Allergic rhinitis occurs in up to 30% of adults and up to 40% of children. Symptoms of allergic rhinitis include sneezing, runny nose, itchy nose and eyes and nasal congestion. Some people may also experience post-nasal drip, allergic shiners (dark circles under the eyes), and a line across the nasal bridge from an upward rubbing of the palm of the hand on the nose, a sign called the “allergic salute.”

Asthma

Allergies are a major cause of asthma, a condition that occurs in about 8% of all people. Though it can occur at any age, it is most often seen in males in the pre-teen years and in females in the teenage years; asthma is the most common chronic disease in children and young adults. Sometimes asthma is difficult to diagnose in very young children, and may require a physician who is an asthma specialist.

Symptoms of asthma may include:

- Coughing — This can be the only symptom in some people who have “cough-variant asthma.” The cough is often dry, hacking, and may be worse with allergic triggers and after exercise. The cough may only be present at night. Cold air may also trigger this symptom.

- Wheezing — This is a high-pitched, musical-like sound that can occur with breathing in and out in people with asthma. Wheezing usually occurs along with other asthma symptoms, may get worse with exercise and with allergic triggers.

- Shortness of breath — Most people with asthma feel as if they’re not getting enough air at times, particularly when they are physically exerting themselves or when an allergic trigger is present. People with more severe asthma have shortness of breath at rest or wake-up with this symptom during the night.

- Chest tightness — Some people describe this as a sensation that someone is squeezing or hugging them. Children may say that their chest hurts or feels “funny.”

Many asthmatics have symptoms with exercise; this does not necessarily mean that their asthma is severe or uncontrolled.

Neelima Reddy asked:


Itchiness, watery eyes, runny nose, sneezing, and redness are some of the common symptoms that majority of the people experiences as allergy symptoms.

The most effective way to fight against particular allergen is immunotherapy or allergy shot, but some people will get frightened to get allergy shot.

Allergy shots hold a little amount of substance that fights against the particular allergen. For example, if the person is allergic to pollen, a small amount of substance called pollen will be added to the shot.

A small amount will be given so that the body will get used to fight against the allergen and if the body comes in contact with that substance next time, body will be familiar with that.

Who are not eligible to take allergy shot?

Allergy shots are not safe for everyone. Although most of the people experienced positive results from these shots, they are not suitable for all. People who are suffering from asthma, heart attack, and respiratory problems, pregnant women, and children under age of five are not recommended to receive allergy shot.

Alternatively, certain individuals are experiencing some side effects such as:

• Feelings of shock when the shot is initially injected

• Lightheadedness

• Nausea

So, for these reasons, the patient should stay in the doctor’s office for at least fifteen to twenty minutes after receiving the shot.

Benefits of allergy shots:

• Allergy shots improve allergic rhinitis, hay fever, bee sting allergies, drug allergies, and eye allergies.

• In some cases, allergy shots improve asthma symptoms also. The most common reaction to allergy shot is swelling at the place where the shot is given.

The success of this immunotherapy varies from person to person depending on the severity of the person’s allergy and the number of substances the person is allergic to.

In addition to the traditional allergy shots, there are new approaches to immunotherapy procedures to treat allergies.

Oral immunotherapy works similar to the allergy shot. In this method, increasing doses of allergen will be given to slowly build up the patient’s tolerance. The only difference with oral immunotherapy from allergy shot is with oral immunotherapy extract of allergen is used as drops. In this method, generally the drops are placed under the tongue and then swallowed.

Intranasal immunotherapy method involves intranasal administration of grass and house dust mite allergen extracts, which reduces the nasal symptoms such as “nasal allergy”.

The side effect with intranasal immunotherapy is nasal irritation. When compared to the traditional allergy shots, intranasal immunotherapy has no long lasting benefits.

Rush immunotherapy involves quick build up to the maintenance dose of extract. In this method of treatment, during early phase increasing doses of allergen will be given every few hours rather than a few days. Since there is a great risk involved with this rush immunotherapy, this should be done in hospital under close supervision.

Some people will experience severe reaction to the allergy shot, which is called “anaphylaxis”. In case of bad reaction with this shot, physicians will do appropriate treatment to stop this reaction.

Since allergy shots are not good for everyone, talking to the physician before taking this shot is more advisable. Visit Allergy Symptoms

Eric Morgan asked:

Here are some basic answers to questions you may have regarding allergen immunotherapy, also known as “allergy shots.”

Allergen immunotherapy is a treatment designed to decrease nasal allergies (also known as allergic rhinitis), allergic asthma and reactions caused by insect stings. Specific allergens are identified through allergy testing, so the allergist first knows what is causing the allergy symptoms, in order to effectively treat them. After the culprit has been identified, allergen immunotherapy involves getting injections of increasing amounts of specific allergens over the course of several months.

Does Immunology Work?

Aside from decreasing allergy symptoms like sneezing, runny nose and congestion, Immunotherapy can help prevent the development of new allergies. In children, Immunotherapy can help prevent allergic rhinitis from progressing into asthma. Even after the treatments have stopped, allergen immunotherapy often leads to long-lasting relief of allergy symptoms.

Many studies have shown that immunotherapy is effective for the treatment of nasal allergies, for both adults and children. A review of 18 published studies involving nearly 800 patients concluded that immunotherapy is highly effective in the treatment of allergic rhinitis. An extensive review of immunotherapy as a treatment for allergic rhinitis in children, showed that the only treatment able to affect the natural cause of the disease is immunotherapy. Studies showing the effectiveness of immunotherapy suggest that roughly 8 out of 10 allergy patients benefit significantly from immunotherapy.

Immunotherapy may also prevent the onset of asthma, and a review of multiple studies showed that allergen immunotherapy is also an effective treatment for asthma. These studies have indicated that treatment with immunotherapy results in reduced symptoms of asthma and improved pulmonary functions, and at the same time, reduces the need for asthma medications.

For individuals with a previously demonstrated allergic susceptibility to insect stings, immunization with insect venom is an extremely effective treatment for preventing future allergic reactions. A review of nine published studies indicates that a course of immunotherapy is highly effective in the management of insect sting allergy. Immunology can be a great alternative if you have any of the following concerns:

Poor response to medications

Impractical or impossible to avoid the offending allergens

Negative medication side effects

Wanting to avoid long-term medications or reduce the cost of medications

Coexisting allergic rhinitis and asthma

Possible prevention of asthma in children

Individuals with allergic asthma

If Immunotherapy Works Why Doesn’t Everyone Do It?

People who have very light symptoms or have found an effective medication that eliminates symptoms, may not need immunotherapy. For others, the time and commitment involved in starting and undergoing immunotherapy can be seen as an obstacle, especially when looking for a “quick fix”. In time however, more and more patients are realizing that the long-term benefits of immunotherapy are much better than having to be on medications for the rest of their life.

Who Is a Good Candidate for Receiving Immunotherapy?

Immunotherapy is recommended for those with allergic asthma, allergic rhinitis (involving various nasal symptoms) and conjunctivitis, or stinging insect allergy. It may be the best option for those who have difficulty controlling symptoms through avoidance or medication. Other considerations are that you do not like the side effects of allergy medication, the allergy medications are inconvenient, or having to take multiple medications in order to control symptoms. Immunotherapy is not recommended for those with food allergies. The best treatment for severe food allergies is to strictly avoid the offending food. The decision to begin immunotherapy will be based on several factors including:

Length of allergy season and how severe symptoms are.

How well medications and/or environmental controls take care of the allergy symptoms.

Wanting to avoid long-term reliance on medication.

Immunotherapy will require a significant time commitment-are you willing to make the commitment to the therapy?

Cost: may vary depending on insurance coverage.

Will Insurance Pay For Immunology?

Most insurance companies and HMOs will pay for immunotherapy, especially if your primary care doctor refers you to an allergist and the allergist recommends immunotherapy as part of your treatment. Even patients with milder symptoms may be recommended immunotherapy to avoid worsening of symptoms, particularly if they cannot always avoid the things they are allergic to, such as a family pet, bee stings, or specific native plants.

How Is the Treatment Administered?

A very small hypodermic syringe is used to inject commercial allergen extracts. The injections are usually at the site of the loose tissue over the back of the upper arm, between the shoulder and elbow. This area is the least painful site for injection as there are very few nerve endings. Injections are given under the skin (”subcutaneous”). When administered correctly, the injections should only be slightly uncomfortable. They are not usually painful, and are well tolerated by adults, teenagers and most children. You may be advised to take an antihistamine a few hours before each injection to reduce the likelihood of any local allergic reaction and other side effects.

Can Young Children Receive Immunotherapy?

Children over the age of 5 may be good candidates for the therapy. Very young child will likely have difficulty cooperating with the immunotherapy regimen. However, immunotherapy can be a good option for children in general. Studies suggest that immunotherapy treatments may prevent the development of new allergies in children, and may help prevent the development of asthma in children who have rhinitis.

Is There an Age Limit to Receiving Immunotherapy?

Not really. Anyone from age 5 on up may benefit from receiving immunotherapy. With elderly persons, consideration should be given to the overall health and chronic medical conditions (such as cardiac disease), which could potentially cause problems. However most healthy children and adults can benefit from Immunotherapy treatments.

Where Does the Immunotherapy Take Place?

Ideally, immunotherapy should always be given in the prescribing allergist/immunologist’s office/clinic. If this is not possible for some extenuating circumstance, your allergist/immunologist should provide the supervising physician with all needed information about your specific treatment. Either way, you must always be in the care of an appropriate medical professional, who is qualified to administer Immunotherapy.

Darrin Reservitz asked:


The different types of allergies can also have varying manifestations. The most common allergy symptoms affect the nose, sinuses, eyes, air passages, ears, skin, and gastrointestinal tract. If we were to name the different types of allergies based on the manifestations they have, there would be three major groups: respiratory, skin, and anaphylaxis.

The most common respiratory types of allergies involve rhinitis and asthma. These two usually manifest reaction in the nose, sinuses, and the other respiratory organs. Allergic rhinitis, for instance, is the inflammation of the nasal cavity and may cause symptoms such as a runny nose, fits of sneezing, congestion, and a sore throat. Allergic asthma, meanwhile, makes a person experience breathing problems, such as gasping, wheezing, chest tightness, et cetera. The most common allergy relief products that address the symptoms of both rhinitis and asthma are antihistamines.

Skin allergies, on the other hand, usually manifest themselves in the form of rashes. Some of the more common skin allergies are eczema, which is an inflamed thick rash that sometimes scales off; urticaria, which is an itchy rash that can be as small as pimples or as big as irritated insect bites; and contact dermatitis, which results in swollen rashes that may even ooze fluid and is sometimes caused by exposure to poisonous plants or highly allergenic materials. Skin allergy sufferers must refrain from touching their rashes. They can treat the irritation with allergy relief products such as specific salves or ointments. These types of allergies that involve the skin may call for consultation with a professional.

The most serious of allergic reactions is anaphylaxis. Different types of allergies may trigger anaphylactic shock, which can lead to death. Shellfish, nuts, eggs, insect stings, and some drugs can bring forth anaphylactic shock. Anaphylaxis affects your body by causing your blood pressure to drop, triggering fainting spells, making your face swell, and hindering normal respiration. There are allergy relief products that can address anaphylaxis and their immediate use is of great import.

It will serve anyone well to arm himself with information about various types of allergies and the specific allergy relief products to treat the symptoms. Even if a person does not have allergies, it would still be beneficial for him to know what to do in case he encounters somebody who is having an allergic reaction and may need his help. Knowing about allergies can save lives.

Alisha Dhamani asked:


Allergy shots are given to some people who have persistent and disruptive allergy symptoms. The shots do not treat symptoms, but by altering the immune response they prevent future reactions. (This is referred to as immunotherapy.) Treatment involves a series of shots, each containing a slightly greater amount of the antigen(s) that cause the reaction. Ideally, the person will become “desensitized” to the antigen(s) over time. The effectiveness of shots varies by individual.

Anti-allergy medications are of many types. The choice of medication and how it is given depends on the severity of the reaction.

For relief of long-term allergies such as hay fever or reactions to dust or animal dander, the following medications may be prescribed.

Long-acting prescription antihistamines, such as cetirizine (Zyrtec), fexofenadine (Allegra), and loratadine (Claritin), can relieve symptoms without causing sleepiness. They are meant to be taken for months at a time, even indefinitely. Most have to be taken only once a day and last for 24 hours.

Nasal corticosteroid sprays are widely prescribed for nasal symptoms not relieved by antihistamines. These prescription medications work very well and are safe, without the side effects of taking steroids by mouth or injection. These sprays take a few days to take effect, and must be used every day. Examples are fluticasone (Flonase), mometasone (Nasonex), and triamcinolone (Nasacort).

In some people, cromolyn sodium nasal spray prevents allergic rhinitis, inflammation of the nose that occurs as an allergic reaction. Decongestants can restore sinus drainage, relieving symptoms such as nasal congestion and swelling and runny nose and sinus pain (pain or pressure in the face, especially around the eyes). They are available in oral forms and as nasal sprays. They should be used for only a few days, as they may have side effects such as high blood pressure, rapid heartbeat, and nervousness.

Self-care at home is not enough in severe reactions. A severe reaction is a medical emergency. Do not attempt to treat or “wait out” severe reactions at home. Go immediately to a hospital emergency department. If no one is available to drive you right away, call 911 for emergency medical transport. For more information on what to do in a severe reaction, see Anaphylaxis.

An oral antihistamine, such as diphenhydramine (Benadryl). Caution these may make you too drowsy to drive or operate machinery safely. They can affect concentration and interfere with children’s learning in school. These medications should be taken for only a few days. For rashes, an anti-inflammatory steroid cream such as hydrocortisone
