Do latex allergens potentiate other skin tests?
We report the case of a 33 year old atopic female patient, who worked for the last 4 years as a cleaner in the surgical area of a hospital. One year after starting the work in this area, the patient noticed upper respiratory symptoms and soon later dyspnea immediately after entering the operating room. Other allergic symptoms were perennial rhinoconjunctivitis and urticaria after contact with peaches. Common skin prick tests were positive for Dermatophagoides pteronyssinus. Fifteen min later a skin prick test with latex was done with a strong positive result after 10 min. At the same time, several allergens (cat dander, grass and olive pollens) showed positive results. The patient experienced a fall in the FEV1 that returned to basal levels after two inhalations of a bronchodilator. New skin tests to common allergens performed one week later were only positive to mites.
