Pruritus of the elderly

Area of Science:

• Geriatrics
• Dermatology
• Internal Medicine

Background:

• Pruritus, an unpleasant itching sensation, is frequently observed in the elderly population.
• While often indicative of underlying skin disease, pruritus in older adults can present unique diagnostic challenges.
• Bullous pemphigoid is a notable dermatological condition that frequently manifests with pruritus in elderly patients.

Purpose of the Study:

• To review the common etiologies of pruritus in the elderly.
• To highlight the differential diagnosis of pruritus, including skin diseases, drug side effects, and idiopathic causes.
• To emphasize the increased prevalence of bullous pemphigoid as a cause of pruritus in this demographic.

Main Methods:

• Literature review of studies on pruritus in the elderly.
• Analysis of diagnostic approaches for elderly patients presenting with pruritus.
• Discussion of specific conditions associated with geriatric pruritus, such as bullous pemphigoid and drug-induced pruritus.

Main Results:

• Pruritus in the elderly is commonly associated with skin diseases, similar to younger individuals.
• Bullous pemphigoid is a more frequent cause of pruritus in the elderly compared to other age groups.
• Pruritus sine materia (without apparent skin disease) is common, with potential causes including drug side effects and idiopathic senile pruritus.

Conclusions:

• A thorough diagnostic evaluation is essential for managing pruritus in the elderly.
• Clinicians should consider bullous pemphigoid and medication side effects in the differential diagnosis.
• Idiopathic senile pruritus, likely related to aging, remains a diagnosis of exclusion.
