Daily Diet: Milk Allergy Relief Drug on the Horizon
Allergies affect approximately 40 percent of children in America and allergic disorders rank #1 among children’s chronic diseases. Food allergies, which affect 5 percent of children, can be one of the more dangerous types, and in some cases requires constant vigilance of every bite of food a child takes. But help may be on the way for those with milk allergies, and maybe even those who suffer from reactions to peanuts, eggs, and other common foodstuffs.

Xolair, manufactured by Genentech, is an asthma drug that is in trials to test the effects of allergy desensitization. A small preliminary study was conducted simultaneously at Stanford University Hospital and Children’s Hospital Boston, where they found that the drug helped to quiet an overactive immune response to dairy. Due to its success, a larger study has already been launched and is currently ongoing.

The initial study involved eleven children with severe dairy allergy. On an allergy scale of 1 to 100, the children ranked at the high end, all in the 90th percentile, which equates to severe allergic—and possibly life-threatening—reactions. Over the course of nine weeks, the children received injections of Xolair, which blocks the immune protein IgE. They then took the medication for an additional two to three months, while slowly increasing their intake of milk, working up to two ounces per day. For two more months, the children had a daily milk intake of two ounces.

If you still have symptoms despite efforts to avoid allergens, you might explore medication options. Whether you choose medication, read the product labels and know the side effects. The following list includes the treatment of allergy more common (both OTC and prescription) and specific allergic conditions and their treatments. In particular, when treating children for allergies, it is wise to consult with your health care provider of the new systems. Some medications are not as effective in children, and some medications can affect the behavior and sleep, and cause serious side effects.


Antihistamines - As the name implies, antihistamines counter the effects of histamine released during an allergic reaction. They are widely used to treat many allergy-related conditions. They are often combined with decongestants and are available in a variety of formulas over the counter (such as Advil ® Allergy Sinus, Alavert Allergy & Sinus, Benadryl, Chlor-Trimeton, Claritin, Contact, Dimetap, Robitussin cough and allergy Triaminic Cold and Allergy, Allergy and Tylenol) and prescription (such as Allegra, Clarinex and Zyrtec). Some may cause drowsiness and slowed reactions. Others do not. antihistamine nasal sprays are also available to treat allergic rhinitis (eg, Astelin). Antihistamine eye drops can also be used for quick relief of itchy eyes associated with allergies (such as Patanol).

Leukotriene blockers - Leukotrienes are another substance released in the body that trigger allergy symptoms such as runny or stuffy nose, sneezing, itchy eyes, runny nose or wheezing. Montelukast sodium (Singulair) is a prescription drug that can prevent symptoms by blocking leukotrienes. It is used in adults and children as young as 2 years. Also used to treat asthma.

Decongestants - People who experience nasal congestion (stuffiness) due to allergies or sinusitis sometimes consider oral decongestant or nasal spray for relief. Decongestants are also included in eye drops to reduce redness caused by conjunctivitis. They work by constricting blood vessels and reduce swelling. Be careful when using some nasal spray decongestants. If used for a long time (more than 3-4 days), you may experience a rebound effect, where nasal congestion symptoms return. Concerns have been raised about oral decongestants and their side effects and abuse potential. Now available behind the counter. Consult your pharmacist.

Corticosteroids - These anti-inflammatory agents used to treat itching and swelling associated with a variety of allergic disorders. The most commonly used forms are corticosteroid nasal sprays for allergic rhinitis and sinusitis (such as Flonase, Nasalide, Nasocort, Nasonex, Rhinocort), nonprescription, topical corticosteroid creams for hives, dermatitis, insect stings and reactions , and inhaled corticosteroids for asthma. Corticosteroids orally or injected less frequently used for more severe cases of asthma, dermatitis or other allergic reactions.

Cromolyn Sodium / Nedocromil Sodium - These are another type of anti-inflammatory drug. Cromolyn sodium nasal spray can be used to treat and sometimes prevent allergic rhinitis. It works by preventing the release of histamine from mast cells. Cromolyn nasal spray is available without a prescription and is gentle and effective. It usually takes a few days to start working. Eyedrop versions are available for itchy, bloodshot eyes. Inhaled nedocromil sodium is used to treat asthma inflammation, which can be exacerbated by allergies.

Epinephrine - Epinephrine (adrenaline) is used for emergency treatment in cases of anaphylaxis from insect bites, food or drug allergies. It is most commonly administered with a device called an injectable epinephrine kit (such as EpiPen or Twinject). Epinephrine constricts the small blood vessels in the skin and mucous membranes, which increases heart rate and blood pressure to normal levels. Epinephrine also is an antihistamine.

Pork Allergy

Posted by Gagan Masoun 0 comments

Almost everyone loves to eat pork. Swine meat is the most common meat in the market. Common as it may be for consumption, at present there are very rare cases of pork allergy. The immune system overreacts to the proteins found in pork. It can put up a variety of defense mechanisms (called antibodies) against these proteins that are perceived as “harmful” to the body.


Mechanism of the Allergic Reaction
Like most food allergies, proteins found in pork are what trigger an allergic reaction in humans. Specifically, the 65-kDa protein is the main allergen found in pork meat. For those who have this rare allergy, the body’s immune system reacts to the intake of the allergen stimulating a type 1 hypersensitivity reaction consequently casting symptoms abdominal symptoms, asthma, rashes, sneezing, and breathing problems. Allergy to pork is said to be prevalent in patients with severe food allergy. Those with a bad case of childhood asthma have a higher risk of developing complications from the allergic reaction.

In some cases, the allergic reaction may not be caused by the animal itself, but from the chemicals used to process pork meat such as papain (used as a meat tenderizer) or casein (used as a stabilizer). Certain chemicals and preservatives contaminate and mix with the protein of the food and are the major causes of food allergies. A least common source of pork allergy is the use of antibiotics to the farm animals. When the animal is injected with antibiotics such as penicillin prior to processing, these drugs may potentially enter into a person’s system who may be allergic to that certain drug.

What Your Doctor Can Do For You
What makes it difficult to identify the food allergen in some people is that they may not be aware of the relationship between the offending agent and their symptoms because the symptoms may appear at a later time. More often, people are sometimes confused with what really causes their allergies due to the variety of food they consume. This is why food challenges are performed. Food elimination diets may also be necessary to rule out any other culprits. However, they may take longer periods in order for the allergy to be diagnosed; hence, laboratory tests are the most frequent method of diagnosis.
A skin prick test must be properly conducted by medical professionals to detect if you have pork allergy. Once tested positive, be very wary of the following symptoms:

- Feeling of warmth
- Itchiness and hives
- Abdominal upset
- Headaches
- Nausea and vomiting
- Wheezing
- Breathing difficulties
- Asthma attacks

A more severe reaction would lead to anaphylaxis where in the body experiences generalized urticaria (hives), sudden drop in the blood pressure, swelling of the lips, tongue, and throat that may cause breathing difficulties. If the swelling continues, the airway may become fully obstructed compromising oxygenation which is highly fatal in a matter of minutes.

Allergies are a medical emergency as they have the potential to progress into anaphylactic shock. Fortunately, they are highly manageable with drugs like antihistamines and corticosteroids to relieve the symptoms. Individuals with food hypersensitivity should avoid the foods that cause their allergies.

What You Can Do
Many people lose their sensitivity to food allergens over time, although not entirely for some. You should always be mindful in what you take.

The safest way to prevent pork allergy is avoidance of pork meat and products that include it in the list of ingredients. Adults as well as children should learn to scrutinize food labels and ingredients carefully.

Some medications and food supplements will help ease the symptoms, such as quercitin, bromellain, vitamin A, eucalyptus, L-carnitine and iron.

Quercitine is more popularly known as flavanoid. These are potent antioxidants that can reduce inflammation, strengthen the immune system and blood vessels, thus improving overall blood circulation. It blocks the histamines effectively. Bromellain will further enhance the absorption of quercitin and must be taken along with it.

Vitamin A greatly improves the immune system’s function. While eucalyptus oil, poured into boiling water (inhalation of its steam) will provide relief of the respiratory symptoms. Iron is vital for blood production and is an important element of hemoglobin (oxygen-carrying substances in the blood).
L-Carnitine will act as a detoxifying agent to the cells and decrease the allergens in our system.
Remember that if you have confirmed your allergy to pork, always find a good doctor specializing in allergies first before practicing the do-it-yourself treatments aforementioned. This article is purely educational and informative. Always guard yourself by being safe.
