Emerging Methods to Objectively Assess Pruritus in Atopic Dermatitis.

Area of Science:

• Dermatology
• Medical Technology
• Biomedical Engineering

Background:

• Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by intense pruritus (itch).
• Pruritus significantly impacts patient quality of life, yet objective measurement tools are lacking.
• Standardized methods are needed for accurate pruritus assessment in AD.

Purpose of the Study:

• To review emerging objective, patient-centered tools for assessing pruritus in atopic dermatitis.
• To highlight technologies developed or enhanced over the last decade.
• To provide clinicians and researchers with an overview of novel assessment methods.

Main Methods:

• Literature search conducted in Medline, Embase, and Web of Science databases (February 2019).
• Keywords included "pruritus," "itch," "atopic dermatitis," and various measurement technologies (e.g., accelerometer, MRI).
• Prioritization of studies from the last decade (2009-2019) focusing on emerging methods.

Main Results:

• Identified emerging methods including video/acoustic surveillance, wrist actigraphy, smart devices, vibration transducers, and neurological imaging.
• Reviewed technologies for their mechanisms, applications in research/clinical practice, and validation status.
• Categorized findings based on surveillance, wearable devices, and advanced imaging techniques.

Conclusions:

• A growing array of novel methods for pruritus evaluation in AD offers promise for improved patient care.
• Future research directions include advanced smart devices, biomarker identification, and machine learning for itch processing.
• Emphasis on patient-centered development is crucial for accurate, comfortable, and privacy-respecting itch management in AD.
