[30 cases of occupational latex allergy]

We experienced 30 patients with occupational latex allergy (LA) in a 4-year period between 1995 and 1998 in Fujita Health University Hospital. All of them were medical personnel. We studied clinical symptoms and the clinical relevance of latex specific IgE and skin test (prick test and use test) in 30 cases. As a result, skin test result was most related of the diagnosis and the severity of LA. The average of the duration to decide LA diagnosis was 21.2 months. The reasons of the delayed diagnosis were that they were left and treated as an unexplained urticaria or asthma. Therefore, we have to warn about LA to the medical personnel who are frequently exposed to latex in Japan.
