Notes:
An epidemiological study is made to evaluate the present or past relevance of positivity to the allergens pertaining to the GEIDC standard series. A retrospective study was made of patients evaluated with patch tests corresponding to the GEIDC standard series by 14 GEIDC dermatologists in the course of 2001. The following parameters were evaluated: age, sex, positive allergens, and present, past and total relevance. A total of 3343 patients were studied, of which 1892 had at least one positive test (56.59%). The most relevant allergens were mercaptobenzothiazole (93,93%), thiuram mix (93%) and nickel sulfate (92.33%). In women, paraphenylenediamine was moreover also very relevant, while in males epoxy resin, butylphenol formaldehyde resin and colophony were particularly relevant. Among the less relevant allergens in both sexes, we found the following in relation to the total: quinolein (44.44%), lactones (45.45%) and caine mix (48.07%). In 1783 patients with at least one positive test, an evaluation was made of whether allergen relevance was past or present. In 60.78% of the positive tests present relevance was established. The allergens of greatest present relevance were ethylenediamine (100%), budesonide (100%), euxyl K 400 (96.96%), epoxy resin (93.33%), and Quaternium 15 (92.85%). The allergens of least present relevance were nickel sulfate (36.38%), caine mix (40%), and neomycin (41.37%).Determination of the relevance of positive patch test is fundamental in all cases. In our study nickel and rubbers were the most relevant allergens, though nickel was essentially of past relevance. Few studies have addressed the present or past relevance of the standard allergen series.
