808 nm diode laser in the treatment of Hidradenitis Suppurativa: a retrospective study

Abstract

Hidradenitis suppurativa (HS) is a chronic, recurrent inflammatory disease characterized by painful lesions such as nodules, abscesses, and sinus tracts, primarily affecting intertriginous areas. Traditional treatments range from antibiotics and hormonal therapies to biologics and surgical options. Recently, lasers and light-based treatments has gained attention as a non-systemic treatment for HS, targeting hair follicles to potentially alleviate symptoms and improve quality of life. This study evaluated the efficacy of 808 nm Diode laser therapy in managing HS by retrospectively reviewing data from 16 patients (13 men, 3 women) aged 23–61 who underwent between two and four sessions. Patients had not received systemic treatment in the three months preceding or during the therapy. Key outcome measures included the Modified Hidradenitis Suppurativa Score (MHSS), Hidradenitis Suppurativa Physician’s Global Assessment (HS-PGA), Hidradenitis Suppurativa Clinical Response (HiSCR), and Dermatology Life Quality Index (DLQI). Results indicated a significant reduction in MHSS from a median of 20.0 before treatment to 9.0 at six months (p = 0.001). The HS-PGA score also significantly decreased from a median of 3.0 to 2.0 (p = 0.012). Of the 10 patients evaluated for HiSCR, 8 showed a positive response. DLQI scores improved from a median of 4.5 to 1.0 (p = 0.002). The treatment was well-tolerated, with only mild pain reported and no severe adverse effects. In conclusion, 808 nm Diode laser therapy appears to be an effective modality for reducing disease severity and enhancing quality of life in HS patients, likely due to its anti-inflammatory effects. These findings suggest that Diode laser therapy could be a valuable addition to current HS management strategies, with further research needed to explore its long-term efficacy.
