Type I[ edit ] The most serious and rare form of latex allergy, Type I hypersensitivity can cause an immediate and potentially life-threatening reaction, not unlike the severe reaction some people have to bee stings.
Many latex mattress companies claim the proteins have been washed out of their latex mattresses. Studies have confirmed that most proteins in latex extract are not present in mattresses and thus must have been washed out or denatured in the processing.
However, some proteins were still present in all 4 natural latex mattresses that were tested. The amount of protein varied greatly. Two had more protein per gram than gloves a known cause of latex allergies. Unfortunately the processing method used when manufacturing the mattresses or even whether they were Dunlop or Talalay mattresses was not specified.
Not all proteins cause allergies. Although we know that proteins are present in latex mattresses, are any of them actually allergens? The studies found that the serum of only 3 out of 21 latex sensitive humans showed an immune response when mixed with the proteins in the mattresses that were tested.
All 21 serums reacted with unprocessed latex extract. Thus most allergens not just most proteins had been removed or denatured during processing; otherwise all the serums would have reacted to the mattresses.
It is important to note that, one of the reactive serums reacted to all 4 natural latex mattresses. Thus some latex allergens were still present in all the mattresses tested.
The reduced number of allergens in mattresses would probably reduce the chance of sensitization to latex and may also mean that even some people with latex allergies would not have a sensitivity to latex mattresses. Nevertheless there are still some latex allergens in latex mattresses.
The question is do people actually become latex sensitized from latex mattresses in real world conditions. After all extreme extraction methods freezing, crushing, and solvents were used to obtain the results above and the extract was directly mixed with serum from the blood of latex sensitive people.
This is very different than lying on a latex mattress where the allergens are bound up in a latex matrix, there are layers of fabric between you and the mattress, and no allergens are being injected into your bloodstream.
Clearly it is possible to get latex allergies from real world exposure to latex without the extreme conditions in the studies. After all tens of millions of people have latex allergies. However, most of these people medical workers, workers in the latex industry, people who have had multiple surgeries — especially at young ages have had very unusual types of exposure to latex.
For instance, latex gloves used by medical workers cause allergies primarily because the latex proteins attach to the powder in the gloves and become airborne and inhaled when the gloves are removed.
This bypasses the protection of the skin. Also, people working in the latex industry are exposed to the raw latex extract which contains far more allergens than latex products.
Furthermore manufacturing puts the latex through mechanical and thermal processes that could cause the allergens to become airborne. Having surgeries involve contact with surgical gloves inside the body.
These are all unusual methods of contact with latex. They do not seem applicable to a latex mattress where the latex itself is rarely touched. Thus the question still remains, is it possible to get allergies from mattresses simply by sleeping on one for a long time.
To my knowledge there has only been one study that looked into whether latex mattresses in real world conditions actually cause latex allergies in humans not just serum in test tubes.
At the age of 3 years, having slept on a latex mattress did not affect whether a child developed a latex allergy. The number was simply the same for the ones who slept on latex mattresses as is was for the ones that did not.Latex is a stable dispersion of polymer microparticles in an aqueous tranceformingnlp.com is found in nature, but synthetic latexes can be made by polymerizing a monomer such as styrene that has been emulsified with surfactants..
Latex as found in nature is a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion consisting of proteins, alkaloids, starches, sugars, oils.
*Most "latex" paints will not cause allergic reactions, but some waterproofing paints will. Check with the manufacturer to be sure. The EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA Panel) has recently updated its previous scientific opinions relating to food ingredients or substances with known allergenic potential.
Disease and Injury. Eight of the 21 priority research areas are grouped in the category of adverse health effects–namely, disease and injury. An earlier effort by NIOSH in the s identified the “top ten” leading workplace diseases and injuries.
Latex allergy and food. Latex allergic people may experience allergic symptoms when they eat certain fruits, vegetables and nuts. Latex is extracted from the sap from the gum tree, Hevea brasiliensis.
