Hidradenitis Suppurativa Clinical Trial
Official title:
Local Control of Hidradenitis Suppurativa After Combination Deroofing and Long-Pulsed 1064-nm Nd:YAG Laser
The purpose of the study is to determine whether a series of laser hair removal treatments can improve participant outcomes after deroofing procedures. A deroofing procedure is a surgery where larger hidradenitis suppurativa bumps (called nodules) and hidradenitis suppurativa tunnels (called sinus tracts) are removed and left to heal open without stitches.

Primary | Disease Activity Changes as Assessed by the Hidradenitis Suppurativa Clinical Response | The Hidradenitis Suppurativa Clinical Response (HiSCR) is a validated score defined as a 50% or greater reduction in abscesses and inflammatory nodule counts with no increase in abscesses and draining sinus tracts at the end of the study period, as compared to baseline. A participant will be considered either positive, or achieving HiSCR, which indicates that the study intervention significantly improved the participant's disease, or the patient will be negative, or did not achieve HiSCR, indicating that the intervention did not significantly impact the participant's disease. Study researchers will calculate this score based on clinical assessment and lesion counts assessed at the first study visit and the last two study visits. The percent of participants who achieve HiSCR at the last two study visits will be reported. | 12 months | |
Primary | Disease Activity Changes as Assessed by the International Hidradenitis Suppurativa Severity Score System | International Hidradenitis Suppurativa Severity Score System (IHS4) changes over the study period will be reported. At each study visit the number of nodules, abscesses, and draining tunnels will be counted in each axilla. The IHS4 score is the number of nodules + abscess count (multiplied by 2) + number of draining tunnels (multiplied by 4). The score can range from 0 lesions and the maximum value is dependent on how many lesions the participant has. The score is used to assess disease severity and can be used to assess how disease severity changes after an intervention. A higher score indicates more active or severe disease, while a lower score indicates less active or less severe disease. Scores throughout the study visits will be reported as well as how these scores change. | 12 months | |
Primary | Disease Recurrence after the Intervention as Assessed by Clinical Exam | During study visits, a study team member will count the number of nodules, abscesses, and tunnels in each axilla. A higher count indicates more active or severe disease, whereas a lower count indicates less active or less severe disease. Scores can range from 0 lesions to as many as the participant has. Differences between the counts throughout the study visits will be reported. | 12 months | |
Secondary | Quality of Life Changes as Assessed by the Dermatology Quality of Life Index | The Dermatology Life Quality Index (DLQI) tool is a validated questionnaire with 10 questions which asks questions related to activities of daily living and how challenging these are in relation a person's skin disease. Answer choices are either yes or no answers or ratings from "not relevant" or "not at all" to "very much" for each question, regarding how their activities of daily living are affected. Scores range from a minimum of 0 to a maximum of 30 with a higher score indicating a worse quality of life. DLQI surveys will be obtained at the first study visit and the final study visit. Score differences between these two visits will be reported. | 12 months | |
Secondary | Pain as assessed by the Visual Analog Scale | The Visual Analog Scale is a 10-point validated pain scale which allows a patient to choose a score between 0 to 10 with depictions of faces showing emotions, with 0 being no pain and 10 being the worst possible pain. This questionnaire will be administered at various points throughout the study and changes over time will be reported. | 12 months |
