Abstract | BACKGROUND: Contact allergy develops in predisposed individuals as a consequence of environmental exposure to allergens. Exposure patterns change over time because of many factors (sex, age, occupation, fashion trends, official regulations), and the delayed hypersensitivity response depends significantly on the age of the subject. OBJECTIVE: The aim of the present study was to investigate the prevalence of contact sensitization in older patients (older than 65 years) referred to our allergologic clinic. METHODS: All patients were patch-tested with the standard series of the Societè Italiana di Dermatologia Allergologica, Professionale e Ambientale, and 32 patients were also tested with additional series. RESULTS: CONCLUSION: These findings suggest an age-dependent decline of overall positive patch-test reactions but a higher sensitization rate to some allergens.
