Topical Chinese Medicine and Exosome Mechanisms for Atopic Dermatitis

3. juli 2026 opdateret af: Chien-Chen Huang, Taiwan Municipal An-Nan Hospital-China Medical University

Efficacy of Distal Topical Application of a Traditional Chinese Medicinal Ingredient for Atopic Dermatitis and Its Exosome-Mediated Regulatory Mechanisms: Basic and Clinical Studies

The goal of this clinical trial is to learn if menthol works to relieve pruritus in atopic dermatitis. The primary objectives are to evaluate the safety and clinical efficacy of menthol-containing gloves and foot-covers, specifically whether they can improve patient-reported Peak Pruritus Numerical Rating Scale (PP-NRS). Secondary objectives include assessing the Eczema Area Severity Index (EASI), the Dermatology Life Quality Index (DLQI), biochemical examinations (including white blood cell count, hemoglobin, GOT, GPT, creatinine, platelet count, and HbA1c), and exosome analysis. Participants will be asked to: Wear menthol-containing gloves and foot-covers (or shams) for 5 minutes per session, following a schedule of 5 consecutive days of use and 2 days of rest each week, over a total period of 28 days. Attend clinic visits on Days 1, 14, 28, and 42 for evaluations and tests.

Foranstaltningsbeskrivelse
Tidsramme
The Peak Pruritus Numerical Rating Scale (PP-NRS)
Tidsramme: PP-NRS will be assessed at Baseline (Day 1), Day 14, Day 28 (end of intervention), and Day 42 (end of study).
This scale uses an 11-point score, from 0 (no itch) to 10 (worst imaginable itch). The scale evaluates the peak pruritus during the past 24 hours.
PP-NRS will be assessed at Baseline (Day 1), Day 14, Day 28 (end of intervention), and Day 42 (end of study).

Foranstaltningsbeskrivelse
Tidsramme
The validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD)
Tidsramme: vIGA-AD will be assessed at Baseline (Day 1), Day 14, Day 28 (end of intervention), and Day 42 (end of study).
It utilizes a 5-point ordinal scale: 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate), and 4 (severe). Each score is anchored to specific morphologic descriptors of skin findings, such as erythema, induration/papulation, oozing/crusting, and lichenification.
vIGA-AD will be assessed at Baseline (Day 1), Day 14, Day 28 (end of intervention), and Day 42 (end of study).
Eczema Area Severity Index (EASI)
Tidsramme: EASI will be assessed at Baseline (Day 1), Day 14, Day 28 (end of intervention), and Day 42 (end of study).
EASI is a standardized tool used to assess the severity of AD. The score integrates the involved body surface area and the severity of skin lesions. Four body regions, including the head and neck, arms, trunk, and legs, are evaluated separately. Each region is assigned a score from 1 to 6 based on the percentage of involvement. Four clinical signs, erythema, papulation or edema, excoriation and lichenification, are rated from 0 to 3. The final EASI score is calculated by the summing of the 4 regional scores, from 0 to 72.
EASI will be assessed at Baseline (Day 1), Day 14, Day 28 (end of intervention), and Day 42 (end of study).
The Dermatology Life Quality Index (DLQI)
Tidsramme: DLQI will be assessed at Baseline (Day 1), Day 14, Day 28 (end of intervention), and Day 42 (end of study).
The index consists of ten questions with four possible responses: 'not at all', 'a little', 'a lot' or 'very much' with corresponding scores of 0, 1, 2, and 3 [48]. The total score ranges from 0 to 30.
DLQI will be assessed at Baseline (Day 1), Day 14, Day 28 (end of intervention), and Day 42 (end of study).
