[Latex allergy--an increasing problem in clinical practice].
In the last few years the allergenic potential of rubber has been receiving more and more attention. Its widespread application in medical devices and everyday objects has increased exposure to this allergen. The central role of rubber in the prevention of HIV infection has certainly played a part in this development. Latex allergy manifests itself as immediate type allergy (type I), delayed type allergy (type IV) or as a combination of both types of hypersensitivity. In this review the different types of latex allergy are illustrated by means of selected case reports. Immediate type allergy to latex leads to contact urticaria, but it may also cause generalized urticaria, bronchial asthma or even anaphylactic reactions (contact urticaria syndrome). Hence, not only dermatologists and allergologists are confronted with latex allergy. Immediate type hypersensitivity can be proven by skin prick test and RAST (radio allergosorbent test). Contact dermatitis in patients using rubber gloves is generally due to delayed type hypersensitivity to rubber additives. However, a recently observed case suggests the possibility of isolated delayed type hypersensitivity to natural latex.
