Notes:
Sensitization rates to contact allergens vary between centers and are influenced by sex and age. Eliminating the latter 2 factors by standardization of data by age and sex, the present analysis address possible differences between centers remaining after elimination of these confounders, and analyzes other factors which might influence rates, e.g. the MOAHL index. Overall standardized rates were well within the range reported in previous studies and may be regarded as representing the rates of the “patch test population” in Central Europe (e.g. nickel sulfate 12.9%, fragrance mix 10.5″. balsam of Peru 7.3%. thimerosal 5.6%). For this analysis, data of those departments which contributed more than 2000 patients or of those with extreme proportion concerning sex, age and occupational cases were selected. Patients from these 10 departments differed considerably will regard to the items of the MOAHL index and with regard to standardized rates. The items of the MOAHL index proved to be suitable for describing different patch test populations and for explaining some differences between centers. Only ‘atopic dermatitis’ seems to have little influence on (standardized) rates. Face dermatitis is not yet represented in the MOAHL index, but should be included, together with age 〉 40 years, in an extended index (acronym: MOAHLFA). Regional allergen exposure (with striking differences between East Germany, West Germany and to a lesser extent Austria) seems to have a great influence on the sensitization pattern observed in a department. In addition, sociological factors may influence sensitization rates, which is exemplified by high rates of nickel allergy in a socially delined subgroup. Future studies should focus on these factors, as well as on factors concerning patch test practices and quality control.
