Efficacy and Tolerability of a Fractional Ablative Erbium Laser for Axillary Scarring for Hidradenitis Suppurativa Patients

Montefiore Medical Center

Overview

Single center, open-label, baseline-controlled study evaluating the use of a Sciton fractionated ablative laser in the treatment of Hidradenitis Suppurativa (HS) scarring.

Single center, open-label, baseline-controlled study evaluating the use of a Sciton fractionated ablative laser in the treatment of Hidradenitis Suppurativa (HS) scarring. The device is FDA approved for the treatment of scarring in all skin types. The study team seeks to observe the efficacy and tolerability in patients without active HS lesions. The study may enroll up to 19 subjects looking for improvement in their HS scarring in the axillary region. The subjects will receive treatment with the Sciton Joule Er:YAG 2940nm laser along with treatment with topical tretinoin, hydroquinone, and hydrocortisone starting 1 month prior to first laser treatment as per standard of care for scar treatment. Each patient will receive 3 treatments spaced approximately one month apart. The patients will be surveyed about their quality of life due to HS scarring, as well as their perspectives on their axillary scarring before and after their assigned treatments. All patients included in the study will have no contraindications to either laser or the use of standard treatment protocol (tretinoin and hydroquinone). Subjects in the laser group will complete a DLQI (Dermatology Life Quality Index) survey, patient satisfaction survey, and clinical photographs at each treatment visit and at follow-up 1, 2, and 3 months after the last treatment. Subjects in the topical treatment group will be evaluated at the initial visit, month 3 and month 6.

Outcomes

Primary Outcomes

Modified Scale for HS Scar Severity (mSHSS)

HS Scar Severity will be assessed in participants using mSHSS as follows: Clear - 0 - No visible scars from HS Almost Clear -1 - Hardly visible from 2.5 m away Mild - 2-Easily recognizable; less than half the affected area Moderate - 3 - More than half the affected area involved Severe - 4 - Entire area involved Very Severe - 5 - Entire area with prominent atrophic or hypertrophic scars

Time frame: Month 0

Modified Scale for HS Scar Severity (mSHSS)

Time frame: Month 6

Secondary Outcomes

Subject Satisfaction Survey

Following treatment participants will be asked to complete a survey in the clinic while referring to their image in a mirror and comparing post-treatment photos versus baseline photos. Scoring will be assessed as follows (-3 = Greatly decreased, -2 = Moderately decreased, -1 = Slightly decreased, 0 = No change, 1 = Slightly increased, 2 = Moderately increased, 3 = Greatly increased) with a lower overall score denoting improvement in appearance.

Physician graded assessment of scar severity

Scar severity will be assessed in participants by way of GAIS (Global Aesthetic Improvement Scale) using photographic assessments. Scoring will range from -3 (greatly worsened scar severity) to 3 (greatly improved scar severity). A score of zero represents no change in scar severity.
