title: Allergic reaction to latex: a risk factor for unsuspected anaphylaxis.
abstract: Allergic reactions to latex, including anaphylaxis may be a problem in certain individuals exposed to latex. Four atopic patients with symptoms of rhinitis, asthma, anaphylaxis, and/or urticaria upon contact with latex products were studied. The patients showed IgE binding to latex RAST disks ranging from 1.0 to 27.3 times the negative control. Latex products (gloves, balloons, and condoms) directly bound IgE from all four patients. Eluted proteins from the latex products inhibited IgE binding to commercial latex RAST disks. SDS-PAGE demonstrated multiple latex protein bands by Coomassie Blue staining between 14 and 66 kD. Immunoblotting showed specific IgE binding to latex proteins at 30 and 66 kD. These results indicate that latex-allergic patients have IgE directed against specific latex proteins. Allergy to latex can pose a substantial health risk to susceptible individuals.
