Biomarker-Based Diagnosis of Contact Dermatitis: A Step Towards More Accurate and Patient-Friendly Testing

Year: 2025

Type: article

Abstract: BACKGROUND: Contact dermatitis (CD) is a prevalent inflammatory skin condition, with diagnostic challenges in distinguishing allergic (ACD) from irritant contact dermatitis (ICD). This study aimed to explore cholesterol-derived biomarkers as potential diagnostic tools. As cholesterol derivatives play key roles in skin barrier integrity and inflammation, they are promising candidates for assessing skin barrier disruption in CD. METHODS: Stratum corneum samples were collected by tape stripping from experimentally induced and chronic lesions, as well as healthy non-lesional skin. Biomarkers Cholesterol Sulfate (Chol-Sulf), Cholesterol Glucosyl (Chol-Glc) and their ratio were quantified. Data were analyzed using ANOVA, Pearson's correlation, logistic regression and ROC curves. RESULTS: Chol-Glc and the Chol-Glc/Chol-Sulf ratio differed significantly across the diagnostic groups, while Chol-Sulf did not. Logistic regression and ROC analyses revealed a limited standalone diagnostic accuracy for the individual biomarkers (all AUC < 0.6). CONCLUSIONS: Chol-Glc and the ratio exhibit disease-specific patterns relevant for subtype discrimination. Although insufficient as independent diagnostic tools, these markers may contribute to future multivariate diagnostic models for CD diagnosis.
