What Are Risk Factors for Latex Allergy?

Discussion Latex comes from the Hevea brasiliensis plants. There are multiple potentially allergenic polypeptides within the plant’s fluid called Heb b 1-13. True sensitizers are Heb b 1, 5 and 6. Heb b 8 and 12 are cross-reacting proteins. The type of the latex product and how it is prepared makes a difference in exposure to the latex allergens. Certain extruded latex products such as catheters and rubber stoppers have higher concentrations of true sensitizer allergens. Products made from molds such as gloves have higher concentrations of potential allergens than latex made in sheets such as such as dental dams. Use of powder substances in gloves also increases latex allergen exposure. Cross reactivity with certain foods is called latex-fruit syndrome and includes apples, avocado, chestnuts, banana, kiwi, tomato, bell pepper and carrot. Ficus trees also have some cross-reactivity. Diagnosis of latex sensitivity and true allergy in the US is usually made by skin prick test conducted in a clinical setting by an allergist. Treatment can include various immunotherapies with the assistance of an allergist. Indications for allergy testing can be found here. Avoidance of latex products is the best option but it’s difficult to do as latex products are all around us in our environment including clothing (undergarments, socks, bathing suits), sports equipment (balls, grips, masks), condoms, rubber bands or erasers, carpet backing, etc.. In the medical areas, latex in glov...
