Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition that can be challenging to treat. Biologics and targeted small molecules have become an increasingly popular area of investigation for therapeutic development for moderate-to-severe HS, though only three biologics-adalimumab, secukinumab, and bimekizumab-have received US Food and Drug Administration (FDA) or European Medicines Evaluation Agency approval for treating HS. Promising agents under investigation are targeting interleukin 17A/F, JAK/STAT pathway, interleukin 36, interleukin 1, and more.

Lai PT, Tseng HC. Adopting adalimumab combined surgery in the management of moderate to severe hidradenitis suppurativa: Experience from a single medical center in southern Taiwan. J Dermatol 2024. [PMID: 39032108 DOI: 10.1111/1346-8138.17375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2024] [Revised: 06/05/2024] [Accepted: 06/21/2024] [Indexed: 07/22/2024]
Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory disorder primarily affecting the intertriginous and anogenital regions. Guidelines recommend various treatments for HS, including biologic agents like adalimumab for moderate to severe cases. Adalimumab is a type of human monoclonal IgG1 antibody designed to target tumor necrosis factor α. Recent studies have shown the effectiveness of adalimumab, either alone or combined with surgery, in managing HS. We retrospectively analyzed the medical chart of HS patients in a southern Taiwan medical center from 2019 to 2022 and investigated clinical features and treatment response. The institutional review board at Chang Gung Medical Foundation granted approval for the study. We primarily focused on moderate to severely affected patients. One hundred and two clinically diagnosed HS patients participated, with a male-to-female ratio of 2:1 and an average age of 31.8 at diagnosis. Among them, 41.2% were in Hurley stage III and 32.4% in stage II. Nineteen patients received excision with pre-surgical adalimumab; their average age at diagnosis was 31.1, with a gender ratio of 5.3:1. Surgery was most common on the buttocks (68%), axillae (21%), and groin (10%). Excision patients were primarily in advanced stages (Hurley III 94.7%, II 5.3%) with high body mass index. Adalimumab and surgery combined yielded a 68.4% improvement rate, while 15.8% remained stable and 15.8% did not respond as expected. In addition, smoking and obesity were prevalent among patients. Adalimumab showed promising results in moderate to severe HS, with significant improvement observed in our cases. The combination of adalimumab and surgery appeared effective in advanced HS patients with larger involved areas and more tunnels. No severe adverse events were reported. However, our study was limited by its retrospective nature and the lack of a control group. Despite these limitations, our study revealed the benefits of integrating adalimumab with suitable surgical procedures in managing patients experiencing moderate to severe HS in real-world scenarios.

Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory disease manifesting as painful dermal nodules, abscesses, and tunnels. Activation of the IL-1R/toll-like receptor (TLR) pathway is strongly implicated in the pathogenesis of HS; thus, the role of a key signaling node, IL-1R-associated kinase 4 (IRAK4), was investigated in a noninterventional study (NCT04440410) that enrolled 30 patients with HS. IRAK4 expression was evaluated in blood and lesional, perilesional, and nonlesional skin biopsies. Peripheral blood mononuclear cells (PBMCs) expressed IRAK4, with significantly higher levels in monocytes (P ≤ 0.0001). Ex vivo treatment of PBMCs with KT-474, a targeted degrader of IRAK4, robustly decreased IRAK4 in all immune cell types from healthy volunteers and patients with HS. Ex vivo treatment of TLR-stimulated healthy donor monocytes with KT-474 decreased IRAK4 protein levels and inhibited inflammatory cytokine production. In HS skin samples, IRAK4 protein levels were significantly higher in lesional versus nonlesional tissue (P ≤ 0.0001), and IRAK4-positive immune infiltrate increased with greater disease severity. Multiple inflammatory mediators were upregulated in HS lesional skin, correlating with IRAK4 overexpression. These data confirm the significance of the IL-1R/TLR pathway in the pathogenesis of HS and provide support for ongoing clinical studies evaluating KT-474 in the treatment of HS.

Abstract
OBJECTIVES Hidradenitis suppurativa (HS) is a chronic inflammatory condition characterized by painful nodules, draining tunnels, and fibrotic scarring in intertriginous, hair-bearing areas. The pathogenesis involves follicular occlusion and subsequent rupture, leading to uncontrolled inflammation. Treatment options for HS are limited and lack universal effectiveness. Laser hair removal (LHR) has been explored as a potential treatment; however, the efficacy and appropriate laser modalities remain unclear. This systematic review examined the efficacy and adverse effects of LHR in HS. METHODS A comprehensive literature search was conducted from inception to September 2023 in Ovid MEDLINE, Ovid Embase, and The Cochrane Library (Wiley) with predefined inclusion and exclusion criteria, and a meta-analysis was conducted. RESULTS Ten studies were selected (n = 227 total patients) and included six randomized controlled trials, two nonrandomized experimental studies, and two case series. Various laser modalities, including long-pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG) (n = 115), intense pulsed light (n = 18), Alexandrite (n = 54), intralesional 1064 nm diode (n = 20), and combined fractional CO2 and long-pulsed Nd:YAG laser (n = 20), consistently demonstrated significant improvement in HS disease severity, irrespective of the disease scoring method used. Minimal adverse effects (primarily mild pain and erythema) were reported. A meta-analysis of three studies utilizing long-pulsed Nd:YAG laser demonstrated a standardized mean difference in disease severity of -1.68 (95% confidence interval: -2.99; -0.37), favoring treatment with LHR for HS. CONCLUSIONS Hair follicles are key in HS pathogenesis and all included studies showed a significant improvement in HS disease severity after LHR regardless of the laser device used, likely related to hair follicle unit destruction. HS is a complex and heterogenous condition, and multiple disease scoring methods complicate outcome comparisons across studies. However, LHR, utilizing various techniques, is an effective treatment option for HS with minimal adverse effects.

Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory skin and systemic disease that is associated with considerable discomfort and a significant reduction in the quality of life. Despite a significantly increased understanding of the disease, the diagnosis is still delayed for many years. Delayed patient access to suitable treatment often leads to disease progression with increased surgical interventions and the occurrence of possible comorbidities. In recent years, there has been an improved understanding of the pathophysiology and, as a result the authorization of modern therapeutic agents for HS. The treatment of HS is based on three treatment pillars: surgery, antibiotics and biologics. Additionally, risk factors, such as smoking and obesity should be positively influenced. Knowledge of comorbidities and their interdisciplinary treatment is important for the individualized care of patients.

Abstract
INTRODUCTION Hidradenitis suppurativa (HS) is an autoinflammatory skin disease with a high unmet need for effective medical management. Clinically, it is characterized by inflammatory nodules that may progress into abscesses, draining tunnels and extensive scarring, mainly affecting apocrine gland-bearing areas. AREAS COVERED Treatment options include topical and systemic medications and a variety of surgical procedures. The anti-TNF-α antibody adalimumab and the anti-IL-17 secukinumab are the only two approved biologics for HS, showing moderate efficacy. HS research is a rapidly growing field, with a wide range of agents leveraging distinct mechanisms of action currently under development. Drugs targeting the IL-17 and Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathways are the most advanced in both ongoing and completed Phase 3 studies, promising deeper levels of response. Use of other, off-label biologics is also discussed. EXPERT OPINION A therapeutic algorithm is proposed based on comorbidities and existing evidence. Patient-tailored combinations between biologics and other biologics or small molecules will hopefully allow clinicians to target most events in HS pathophysiology in a complementary way while obtaining a meaningful effect on their devastating manifestations.

Abstract
BACKGROUND Adalimumab monotherapy for hidradenitis suppurativa (HS) is often insufficient with a maximum clinical efficacy of 60% in Hidradenitis Suppurativa Clinical Response (HiSCR) and limited effect on draining tunnels. Data suggest that adalimumab therapy could be improved by concomitant antibiotics. OBJECTIVE To compare the clinical effectiveness of adalimumab with clindamycin and rifampicin versus adalimumab monotherapy after 12 weeks. METHODS This retrospective study included patients who started adalimumab with additional clindamycin and rifampicin and patients treated with adalimumab monotherapy, matched on sex and refined Hurley score. The primary outcome measure was the difference in change in the International Hidradenitis Suppurativa Severity Score System (IHS4) at 12 weeks. RESULTS In total, 62 patients were included in the combination therapy group (n = 31) and adalimumab monotherapy group (n = 31), showing comparable IHS4 scores; 32.5 versus 29, p = 0.87 at baseline respectively. The combination therapy demonstrated greater clinical effectiveness expressed in median IHS4 improvement (-20 vs. -9, p < 0.001), IHS4-55 (74% vs. 36%, p = 0.002), median draining tunnel reduction (-4 vs. -2, p < 0.001) and pain response (47% vs. 27%, p = 0.02). CONCLUSION Adalimumab initiated with clindamycin and rifampicin shows greater clinical effectiveness than adalimumab monotherapy. An important difference in effect was observed in the decrease of draining tunnels, addressing a serious limitation of adalimumab monotherapy.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a debilitating chronic skin disease; its therapeutic approach often requires combined medical and surgical treatment. METHODS The aim of this study was to assess the efficacy and safety of the surgical approach combined with different pharmacological treatments, evaluating the proportion of patients achieving the hidradenitis suppurativa clinical response (HiSCR), along with the incidence of postoperative complications, and local recurrence. A retrospective study of HS patients (Hurley I-III) presenting at least one skin lesion requiring surgery was performed. Demographic and clinical data were collected (kind and anatomical location of lesion excised, type of surgical procedure). Further data included: Hurley stage and IHS4 at baseline and week 16, HiSCR at week 16 after surgery, ongoing therapy at the time of surgery (topical, systemic antibiotic, biologics), postoperative complications and local recurrence at week 16. RESULTS Forty-two patients with female predominance (66.7%, 28/42), with a mean age of 30.3 (SD±10.5) years, were enrolled. At week 16, 53% of patients achieved HiSCR, with baseline Hurley III inversely related to HiSCR achievement (P<0.05). No increased incidence of postoperative complications was detected. Three cases of local recurrence were reported at week 16. CONCLUSIONS The results support the efficacy and safety of the combined therapy in the management of HS; no increased risk of complications emerged among patients concomitantly treated with biologics, compared to those on conventional systemic therapy or exclusively treated with surgery.

Abstract
Hidradenitis suppurativa (HS) is a multifactorial disease involving the skin and subcutaneous tissues characterized by deep-seated, painful nodules and abscesses with draining sinus tracts. It affects mostly younger individuals between the ages of 18 and 34. The discomfort and embarrassment that patients affected by HS experience negatively impact their daily lives. It is associated with decreased quality of life and high rates of comorbid depression and anxiety. The rate of depression in HS was reported to be as high as 26%. Its pathogenesis is multifactorial and as such requires a multimodal approach to treatment, which subsequently is reviewed here. Moreover, the pathogenesis of HS is complex and only partially understood. Autoinflammation is the key driver of disease development and is linked with dysregulated inflammasome activation with the subsequent production of inflammatory cytokines. Genetics and cutaneous microbiome play a role in the development of chronic inflammation and lesion formation. Risk factors such as obesity, metabolic syndrome, diabetes, and smoking also add to the systemic inflammation. Targeting these risk factors is a key aspect of the treatment of HS. Lifestyle modifications are used in conjunction with pharmacotherapy and procedures to effectively manage the disease.
