Understanding latex allergy.
Latex allergy is an increasingly important problem in both health-care workers and patients. Predisposing factors to development of latex allergies include a history of atopy or allergy and frequent exposure to latex products. Identified allergens include latex proteins from the rubber tree that remain in manufactured products, as well as smaller molecules that remain from the latex purification and manufacturing process. Latex proteins absorbed to powder in latex surgical and examination gloves may be aerosolized and inhaled. Powder-absorbed latex proteins are thought to be important in triggering of sensitization in susceptible individuals, as well as in elicitation of symptoms in previously sensitized patients. Allergic reactions to latex can include local dermal reactions or generalized immediate hypersensitivity (anaphylactic) reactions. Pathophysiology, signs and symptoms, and treatment of each type of reaction are discussed. Measures to address latex allergy, however, must include measures to decrease exposure to latex antigens both in latex-allergic subjects, to prevent symptoms, and in naive subjects, to prevent sensitization. These measures may include finding, acceptable substitutes for latex in many products.
