Latex allergy is usually diagnosed in patients from high risk groups (eg. chronically instrumented patients, health care workers, rubber industry workers). The prevalence of latex allergy in non-risk populations is not well documented. We aimed to study the prevalence of skin prick test positivity to latex allergens in patients referred to allergy clinic for consultations unrelated to latex allergy.
The study included 434 consecutive patients admitted to allergy clinic. Skin prick tests with a battery of inhalant allergens were performed. Skin prick test with two different extracts of latex allergen (Soluprick-Alk 1:20 and Alyostal-Stallergens 1:100) were positive (at least 3 mm weal response) in 31 patients (7% of the population studied). Atopy was more prevalent among patients with positive SPT to latex than in SPT-negative patients. Out of 28 patients SPT-positive for latex, there was 11 (39%), who reported immediate local reactions (erythema, pruritius, urticaria) on contact with latex. Latex specific IgE in serum (ELISA) was undetectable in all patients with symptoms of latex allergy.
Our study documented relativelly high prevalence of sensitization to latex allergens in patients referred to allergy clinic, suggesting higher risk of latex allergy in this group of patients.
