title: [Contact eczema and "standard test"--do "International Standard Test Series" coincide with Austrian local characteristics?].
abstract: Testing with a "standard" group of substances has proved of great value when allergic contact dermatitis is suspected and the offending agent cannot be pinpointed by careful history-taking. But internationally standardized series do not take into account locally important and individual factors, changing consumer habits or economic aspects. We have, thus, compared the suitability of two standard series, the ICDRG-European and the DKG-German standard, for Austrian purposes. 1,478 patients with a clinical diagnosis of contact dermatitis were patch tested between 11/88 and 4/90 with the ICDRG allergens; the second collective of 505 patients was tested between 5/90 and 1/91 with the DKG series. Only 12 out of the 27 substances of the ICDRG series exceeded the critical incidence of 1%; 6 were below this limit but positive in more than 0.5% and 9 hardly ever aroused positive reactions. In the DKG series, 17 out of 23 substances surpassed the limit, 2 were positive in more than 0.5%, and 4 caused virtually no reactions. However, 4 allergens with frequent sensitization rates were included neither in the ICDRG nor in the DKG series and 2 others were missing in the over-dimensioned ICDRG standard. Our results demonstrate that internationally established standard series have to adapted for the local situation in Austria, and that a constant review is essential with replacement of allergens as necessary according to changing production techniques and consumer habits. Suggestions for an "Austrian standard patch test series" are proposed on the basis of our results but in spite of being helpful in general terms interpretation of such a test in the individual patient with eczema remains problematic.
