Brief Summary

Hidradenitis suppurativa (HS) is a chronic, recurrent and debilitating inflammatory skin disorder, characterized by painful inflamed nodules, abscesses and tunnels in the skin folds such as the axilla, inguinal region and gluteal area. The primary event in HS is occlusion of the hair follicle. HS is a notoriously difficult to treat disease, because treatment options are limited and evidence based treatments are scarce. Prevention of diseases is an important topic in medicine. However, current clinical trials in HS are focusing on anti-inflammatory drugs in patients with severe HS, whereas prevention and treatment of patients with more common mild HS is neglected. Laser hair removal therapy is a non-invasive procedure with minimal treatment discomfort for patients. Previous limited studies have suggested positive results in favor of laser hair removal therapy in HS. We therefore hypothesize that hair depilation using laser hair removal therapy may prevent the formation of new lesions and flares of the disease. The objective is to assess the efficacy of laser hair removal therapy in patients with mild to moderate HS.

Outcome Measures

Primary Outcomes (1)

  • Difference in IHS4 over time, measured between month 7 to month 12

    The IHS4 will be assessed monthly.

    between month 7 to 12

Secondary Outcomes (21)

  • Cumulative IHS4 over month 7 to month 12 between the two groups

    month 7 to 12

  • Change in skin related pain of the axillae, on a numerical rating scale (NRS), between baseline and month 12, and between groups.

    every month for 12 months

  • Change in skin related itch of the axillae, on a NRS, between baseline and month 12, and between groups.

    every month for 12 months

  • Difference in number of self-reported flares (number of flares reported by the patients in the last 4 weeks), between the two groups during this study

    every month for 12

  • Difference and change in quality of life measured with the Dermatologic Life Quality Index (DLQI) between baseline and month 12 and between groups.

    every month for 12 months

  • +16 more secondary outcomes

Study Arms (2)

Intervention group, laser hair removal therapy

EXPERIMENTAL

Patients will undergo 6 monthly laser hair removal treatments with de Nd:YAG laser. After 6 months, a 6 follow up will start, using clindamycin 1% lotion if needed.

Procedure: Nd:YAG laser hair removal

Control group, clindamycin 1% lotion if needed, standard care

ACTIVE COMPARATOR

Patients will use clindamycin 1% lotion of needed for 1 year.

Drug: Clindamycin 1 % Topical Lotion

Interventions

Using the Nd:YAG laser (cynergy), hair of the axillae will be removed.

Intervention group, laser hair removal therapy

Clindamycin 1% lotion if needed

Control group, clindamycin 1% lotion if needed, standard care

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • IHS4 mild to moderate, without tunnels in the axillae.
  • HS activity in at least one axilla.
  • Age 18 years and over.

You may not qualify if:

  • If the patient is not able or willing to provide informed consent.
