Natural rubber latex allergy in the occupational setting

Over the last decade, the prevalence of natural rubber latex (NRL) allergy has reached epidemic proportions among workers who use or who are exposed to powdered latex products. NRL-associated occupational asthma is confined largely to those exposed to powdered latex glove use or other latex aerosols. The most frequent presenting symptom of NRL allergy is contact urticaria; inhalation may cause symptoms of allergic rhinitis and asthma. Skin prick testing is the most accurate tool for diagnosis of NRL allergy. The cornerstone of management is cessation of exposure; substitution with non-NRL or nonpowdered NRL gloves results in predictable rapid disappearance of latex aeroallergen.
