Brief Summary

Hidradenitis suppurativa (HS) is a debilitating and chronic condition characterized by recurrent episodes of inflammation associated with the formation of abscesses, inflammatory nodules, pain, and drainage ultimately culminating in the formation of scarring in moderate to severe disease. HS affects more women than men in a ratio of approximately 3:1, and onset of the disease is typically after puberty. The axillae, breasts, groin, buttocks, and lower abdomen are common intertriginous regions which are affected by HS, and significant impacts on quality of life are reported in the literature.

The Hurley Staging system is commonly utilized to classify the severity of a patient's hidradenitis suppurativa. Stage 1 disease consists of one or more abscesses with no sinus tract formation or scarring. Stage 2 disease involves one or more widely separated recurrent abscesses, with formation of a sinus tract and/or scarring. Stage 3 involves multiple interconnected sinus tracts and/or abscesses throughout an anatomical area.

Histologic studies of HS suggest that follicular hyperkeratosis and obstruction is the primary event in the pathogenesis. Subsequently, there is rupture of the follicular infundibulum and a resulting inflammatory cascade. Despite recurrent episodes of purulent drainage, bacteria do not appear to play a primary role in the pathogenesis.

The traditional repertoire of treatment options for HS can be divided into medical and surgical options, however there is currently no cure for HS and treatments focus on symptomatic control. Medical treatments including topical and systemic antibiotics, hormonal agents, and biologic medications can successfully control symptoms however discontinuation of many of these is associated with relapses in disease symptoms. Conversely, surgical interventions such as traditional surgical excision performed in an operating room, or carbon dioxide laser excision performed under local anesthetic in an outpatient setting can induce long term symptom control however may not be appropriate for all patients considering the risk of general anesthesia, high cost of inpatient hospitalizations, and cumbersome healing process for procedures which heal by secondary intention. Despite numerous treatment options for HS, efficacious and non-invasive treatment options which result in long term remission of disease are needed to meet the needs of HS patients.

Detailed Description

Subjects receive treatment every 2 weeks for a total of 22 weeks, 10 treatments. Subject treatment side will be randomized via computer generated assignments.

Ultrasound imaging will be utilized to assess abscesses, nodules, and sinus tracts at investigator discretion. Patient-reported outcome measures include DLQI and Pain VAS. Physician-reported outcome measures include: HS-PGA, IHS4, Hurley Staging, and HiSCR.

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: CROSSOVER
• Primary Study Purpose: OTHER
• Blinding Strategy: NONE

Study Groups

Intervention

This is a split body study. The patients will serve as their own control. The side that receives Laight therapy will be randomized. For example, if the patient receives Laight therapy on the right, then the control will be the left.

Group Type: EXPERIMENTAL

Laight therapy, NICE V3.1 device

Intervention Type: DEVICE

Laight therapy is a non-invasive method of treatment for HS and acne developed in Germany which utilizes a combination of radiofrequency and intense pulsed light exposure. Three passes of the device, all coupled with radiofrequency, are used in the proposed treatment area. The first pass encompasses wavelengths between 420 nm and 1200 nm, the second between 510 nm and 1200 nm, and the third pass between 690 nm and 1200 nm.

Control

This is a split body study. The patients will serve as their own control. The control side of the body will be randomized. For example, if the patient receives Laight therapy on the right, then the control will be the left.

Group Type: NO_INTERVENTION

No interventions assigned to this group
