Filter by:Hidradenitis Suppurativa is a recurrent chronic inflammatory follicular occlusive disease affecting hair follicles. HS is notoriously difficult and challenging to treat with a high morbidity impact and could be classified as an unmet medical need with no efficient therapeutic options. Objective: Investigators previously showed that Outer Root Sheath Cells (ORS) isolated from hair follicle of HS patients (HS-ORS) have a pro-inflammatory phenotype and secrete spontaneously IP-10 and RANTES. To identify the mechanisms involved in the pro-inflammatory phenotype of HS-ORS, investigators performed a transcriptomic analysis in healthy and HS patients. This revealed: (i) an IFN signature, (i) a dysregulation of genes involved in cell proliferation and differentiation, and (iii) an upregulation of DNA damage response and cell cycle G2/M checkpoint pathways in HS-ORS. These findings support the notion that, in HS patients, a perturbation of HF-SC homeostasis leading to an increased proliferation induces a replicative stress and an accumulation of cytoplasmic ssDNA, stimulating IFN synthesis through IFI16-STING pathway. Interestingly, replicative stress in ORS were present in some but not all patients with Hidradenitis Suppurativa. The goal of study is to determine replicative stress in ORS in a large cohort of HS patients. Method Patients will be enrolled in the Mondor Dermatology department, during routine care. A dermatologist will check all inclusion and exclusion criteria with the technical support of a research technician of the Henri Mondor Clinical Investigation Center. Medical history, clinical data, comorbidities and concomitant therapies will be prospectively recorded in a dedicated case report form. Skin biopsies will be performed in perilesional zone rich in hair follicles. mRNA will be extracted from freshly isolated hair follicle cells and some slides will be prepared and stored at -80°C to perform immunohistochemistry analysis on freshly isolated hair follicle cells. PBMC and serum will be collected. All these biological samples will allow us to quantify the replicative stress in HS-ORS of each patient, and to quantify several cytokine of interest : IFN de type 1, IL-17, IL-6, TNF-α, IL-10 This study will allow investigators to evaluate the rate of patients with replicative stress in hair follicle stem cells in Hidradenitis Suppurativa. The investigator will also determine whether HF-SC replication stress correlates with clinical characteristics and/or with clinical course and/or comorbidities.
The purpose of this protocol is to examine the cytokine profi le of pati ents with hidradeniti s suppurati va (HS) and idemechanisms responsible for post-transcripti onal regulati on of these genes. The primary objecti ve is to determinfollowing cytokines linked to hidradeniti s suppurati va are diff erenti ally expressed in hidradeniti s pati ents versus controlalso doing a sub-study to determine the eff ect of childhood trauma on HS.

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.
This will be a prospective, interventional, single-center, randomized, controlled, comparative study comparing a total of 10 patients treated with BTM and SOC in wounds diagnosed with Hidradenitis suppurativa (5 in each group).
Single center, open-label, baseline-controlled study evaluating the use of a Sciton fractionated ablative laser in the treatment of Hidradenitis Suppurativa (HS) scarring.
This study will build on data from mice and humans implicating TRPV1 nociceptors in the pathogenesis of the type-17 chronic inflammatory skin disease Hidradenitis Suppurativa (HS). In this study, the investigators will test the hypothesis that inhibiting neuropeptide activity with botulinum toxin reduces pathogenic inflammation.
Izokibep is a potent and selective inhibitor of interleukin 17A (IL-17A) that is being developed for treatment of hidradenitis suppurativa (HS). This study will evaluate the efficacy, safety, and immunogenicity of izokibep administered subcutaneously (SC) in adult subjects with moderate to severe HS.
A Randomized, Double-blinded, Placebo-controlled, Phase 2a Study to Evaluate the Efficacy and Safety of RIST4721 in Subjects with Hidradenitis Suppurativa
This is a study to demonstrate the clinical efficacy and safety of the nanobody® sonelokimab administered subcutaneously (sc) compared with placebo in the treatment of adult participants with moderate to severe hidradenitis suppurativa.
This is a 16-week treatment, randomized, double-blind, proof-of-concept study designed to assess the safety and efficacy of RGRN-305 compared to placebo for use in future efficacy Phase 2 trials. Male or female subjects aged 18 years or older with moderate to severe hidradenitis suppurativa will be included in this study. Objectives are to determine the efficacy and safety of RGRN-305 in patients with moderate to severe hidradenitis supppurativa.
