[Allergy to latex: an underestimated problem]

Three patients who showed an allergic reaction to latex products are described. By means of history, skin tests, measurement of IgE antibodies against latex and challenge tests the diagnosis could be established. To prevent the spread of infectious diseases the use of latex gloves and condoms is increasing. Therefore, the incidence of allergic reactions to latex may also rise. Latex allergy should be considered when evaluating 'idiopathic' anaphylaxis during an operation. Moreover, latex allergy may be the cause of occupational rhinitis and asthma.
