[Latex allergy].

Latex allergy has been described with increasing frequency throughout the last years. The prevalence in Denmark is not yet known. The growing frequency is partly explained by the extensive use of latex-containing products (especially gloves), which has followed the appearance of the HIV-epidemic. The symptoms of latex allergy are usually those produced by type-I hypersensitivity. Type-IV allergy (contact dermatitis) to rubber chemicals is well described but is not directly associated with the latex proteins. The allergens in latex have nearly been identified; diagnostic tools are known but are not yet satisfactory. Cross-reacting antigens are found in banana, kiwi, avocado, chestnut and other plants. It is concluded, that attention to latex allergy has to be intensified and the risk factors reduced, especially concerning the health care units.
