Abstract
BACKGROUND: Score concepts have been suggested for the standardised diagnosis of atopic dermatitis, incorporating various anamnestic and clinical minor criteria of atopy, including the 'Erlangen Score', developed in the hospital-based setting of a dermatitis clinic. OBJECTIVE: To evaluate the properties of this score in the context of a population-based epidemiological study. METHODS: The association between relevant atopic criteria and previous or current flexural eczema was evaluated in 2,352 hairdressing apprentices. RESULTS: The association was not as strong as in the patient-based studies, comparing the respective odds ratios. Accordingly, the discriminating power of the Erlangen Score was poor, resulting in low sensitivity (55.7%) and specificity (73.8%) for, e.g., 8 points as cutpoint. CONCLUSION: While the score appears useful to summarise minor criteria, the individual relevance of its point values should not be overestimated in view of a low positive predictive value in a population (compared to a clinical) setting.
