Prevalence of pruritus in the elderly in an outpatient dermatologic clinic: a monocentric pilot study.

Abstract

Few studies have examined pruritus in elderly patients, a common dermatological condition. The study examines pruritus prevalence and characteristics in elderly patients referred to the Dermatology Unit, at Genoa's Galliera Hospital. The demographic characteristics of all Outpatient Clinic patients with any skin condition were examined, focusing on pruritus patients over 65. Pruritus was present in 36/262 patients (14%; M:F =20:16; mean age: 59.55 years). About 14% of 140 patients aged ≥65 years had pruritus, with 20/262 (8%; M:F =14:6; mean age: 74.6 years) exhibiting it. Visual analog score pruritus did not differ between patients aged ≥65 years (20/36) and <65 years (16/36) statistically. In 89% of patients, itch was related to a dermatological condition, mainly psoriasis. Only extracutaneous diseases resulted more frequently in the patients aged >65. No anamnestic link was found between drug use and pruritus in these patients. We confirm that pruritus is a common skin problem that affects both sexes, young and old, and is almost always caused by an underlying skin condition (mainly psoriasis). It is rarely caused by a new drug.
