Latex allergy: Feature Article

What many people might not realize is that latex allergies are actually on the rise, in fact it has dramatically increased since 1987. The reason for this is that in 1987 there was a huge movement throughout the world to take certain precautions that would help to stop the spread of infectious diseases, such as AIDS. And this movement actually resulted in the universal application of some kind of protective barrier, which was designed to protect a person from infectious material. The most popular type of protective barrier was of course the latex glove and since 1987 it has been reported that the annual usage of latex gloves in the United States alone has been over 10 billion. And because of this huge increase of people using these gloves there has been a huge rise in the allergy to latex. In fact health care workers are at a higher risk because of how often they come into contact with latex, it has actually been shown that the latex allergy affects 2% of all hospital employees. But the scariest thing is that latex is used in over 40,000 products, but the good news is that not all of the products that latex is used in will create an allergic reaction because of the way the product is used.

What is a latex allergy?
The protein that is found in rubber is something that can cause an allergic reaction in some people. And something interesting to note is that the thin stretchy latex rubber that comes in gloves, condoms and balloons to name a few things actually carry the highest amount of this protein, which makes these items more dangerous to people with a latex allergy than other rubber items. But something else that you need to keep in mind if you have a latex allergy is that because of the fact that some latex gloves are coated with cornstarch powder. And because these gloves are coated with cornstarch powder what can happen is that the latex particles can stick to the cornstarch powder and can fly into the air when the gloves are being taken off, which means that you can actually inhale the latex. This is bad for people who have a latex allergy because they might be breathing in this particles without realizing it and by breathing in these latex particles you can suffer from an allergic reaction, just like putting on latex gloves or something similar.

What is latex?
Now that you know what a latex allergy is you might be wondering just what latex is exactly. What you might be surprised to learn is that latex is actually a natural substance. Natural rubber latex comes from a liquid in tropical rubber trees. What happens is that the liquid is processes to make the numerous rubber products that we use both at home and at work. Some examples of the products that are made from latex are:
- Balloons
- Rubber toys
- Pacifiers and baby bottle nipples
- Rubber bands
- Adhesive tape and bandages
- Diapers and sanitary pads
- Condoms
- Medical and dental supplies
- Gloves
- Urinary catheters
- Dental dams
- Material used to fill root canals
- Tourniquets
- Resuscitation equipment
How is a latex allergy detected?
One thing that people don't realize is that the latex allergy can actually come in two different forms, which means that detecting the allergy is going to depend on the form of latex allergy that you have.
- Delayed hypersensitivity - this form of the allergy is usually seen as a skin rash at the site where the latex product contacts the skin. But keep in mind that this rash can actually be very severe. The best way to detect this form of the latex allergy is to place the latex preservatives and accelerators on the skin using a standard patch test. But doctors must use caution with this type of testing because an immediate reaction is possible through the patch testing.
- Immediate reaction - this form is also referred to as anaphylaxis. This type of reaction can result in seriously low blood pressure, breathing difficulty, and can even result in death if severe enough. But you might also see some people who experience irritation of the nasal passages, similar to hay fever. To detect this type of reaction you are going to need to take either a blood or skin test. Something you might want to know is that with how severe a reaction you can get from a skin test the blood test is usually performed first.
What are the symptoms of a latex allergy?
If you have a latex allergy or think that you might have one it is important that you learn some of the basic symptoms of the allergy, but like anything else your latex allergy can be mild or severe, not to mention the fact that you can present some, all or none of the symptoms of a latex allergy. But something else that you need to keep in mind is that a person who is latex sensitive can also have a life threatening allergic reaction with no prior warning to the allergy or any exhibition of symptoms. Here are some of the common symptoms of a latex allergy:
- Itchy, red, watery eyes
- Sneezing or runny nose
- Coughing
- Rash or hives
- Chest tightness and shortness of breath
- Shock
- Bumps, sores, cracks or red raised areas on hands
- Usually appears 12 to 36 hours after contact with latex
Who is at risk of a latex allergy?
Like other types of allergies there are some people who are born with a genetic predisposition to be allergic to latex, although the number of people who are born with this allergy is actually quite low. In fact according to numerous studies in order to become allergic to latex you are going to need to be repeatedly exposed to latex in order to develop the allergy. What this amounts to is that the more you are exposed to latex, especially products that are "dipped" the higher your chances of developing an allergy to latex.
This actually means that the people who are at the highest risk for developing a latex allergy are health care workers because of how often they wear rubber gloves, not to mention the fact that they are constantly in contact with other latex products. But other people who are at a high risk of becoming allergic to latex are people who require frequent surgery or catheter use, and people who work in the manufacturing and/or distribution of latex products. Something to keep in mind is that people who have surgeries of the spine or urinary tract actually have a much higher risk of developing the latex allergy than others. Something interesting that has been discovered when it comes to people being allergic to latex is that there is an association of unique food allergies among people who are allergic to latex. Usually people who are allergic to latex are also usually allergic to bananas. But in some quite a few cases people are also allergic to kiwi, papaya, avocados and apricots. And while the association with the food allergy is real it is still uncertain about the relationship between the two allergies.
How is the latex allergy treated?
Basically if you know you are allergic to latex than you should do everything that you can to avoid any and all latex products. You even want to avoid products that are labeled "safe latex" because they can still cause allergic reactions. If you are allergic to latex the sad news is that there is no current treatment available that will desensitize you to latex. The only known treatments are treatments of the reactions; these options can include antihistamines, adrenaline, and steroids.
Here is an example of a screening questionnaire that can be used to determine latex sensitivity.
