Chronic Pruritus in the Geriatric Population

Area of Science:

• Geriatric Medicine
• Dermatology
• Neuroscience

Background:

• Chronic pruritus, defined as itching lasting over six weeks, significantly impacts the geriatric population (≥65 years old).
• Pathophysiological factors include compromised epidermal barrier function, immune system dysregulation, and nervous system abnormalities.
• Pruritus in the elderly can be classified into histaminergic and nonhistaminergic subtypes, influencing treatment strategies.

Purpose of the Study:

• To review the current understanding of chronic pruritus in the geriatric population.
• To discuss the underlying pathophysiological mechanisms and etiological factors.
• To explore existing and emerging therapeutic options for geriatric pruritus.

Main Methods:

• Literature review of studies on chronic pruritus in older adults.
• Analysis of pathophysiological factors contributing to geriatric pruritus.
• Evaluation of current treatment modalities, including topical and systemic approaches.

Main Results:

• Abnormalities in the epidermal barrier, immune, and nervous systems are key predisposing factors.
• Treatment decisions for systemic therapies consider the specific condition, comorbidities, and potential drug interactions.
• Despite limited current options, significant progress in identifying itch-specific mediators is paving the way for novel therapies.

Conclusions:

• Chronic pruritus in the elderly is a complex multifactorial condition requiring tailored management.
• Topical treatments are generally safe, while systemic treatments necessitate careful consideration of patient-specific factors.
• Advances in understanding itch mediators and ongoing clinical trials promise improved future treatments for geriatric pruritus.
