Acne inversa

BACKGROUND AND OBJECTIVES: Hidradenitis suppurativa (HS)/acne inversa is an intractable skin disease that is characterized by destructive lesions - primarily on the flexural areas. Although its etiology is unknown, genetics is considered to be a factor of its pathology - mutations in γ-secretase genes have been identified in certain familial HS patients, and follicular occlusion is widely accepted as the primary cause of HS. But, no relationship between these mutations and the components of hair follicles has been reported...

Background: Hidradenitis suppurativa is manifested by painful abscesses and scarring of sweat glands. Axillary, inguinal and genital regions are mostly affected. Multiple options exist in the treatment of hidradenitis suppurativa. The aim of this retrospective, mono-center cohort study was to analyze the outcome of different treatment methods after radical excision of hidradenitis suppurativa. Methods: We retrospectively evaluated the treatment strategy and recurrence rate of hidradenitis suppurativa...

Hidradenitis suppurativa/acne inversa (HS) is a chronic inflammatory disease of the pilosebaceous unit leading to formation of painful, inflammatory nodules, abscesses and tunnels in apocrine gland-bearing areas of the skin. Pain and drainage are the most important symptoms associated with reduction of quality of life in HS. On the other hand, an overlooked symptom in quality of life studies is itch, despite the fact that several studies have reported its importance. Various theories have tried to explain the pathogenesis of itch in HS, such as the presence of mast cells in the cell infiltrates and elevated Ig E levels in the lesional skin...

Introduction: Hidradenitis suppurativa (HS) is a chronic inflammatory disease characterized by recurrent nodules, abscesses, and sinus tracts, resulting in scarring. Patients suffer significantly impacted quality of life (QoL), manifested by anxiety and depression. We describe microbial isolates identified from active sites in adults with HS, and explore associations between organisms isolated, disease severity, and QoL. Methods: Observational study over 2 years...

Introduction: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease associated with various comorbidities and diminished quality of life (QoL). Among dermatological conditions, HS is reported to most severely diminish QoL. This study aimed to analyse the health-related QoL (HRQoL) of patients with HS in more detail by using generic to disease-specific HRQoL questionnaires. Correlations between the HRQoL measures and HS disease severity measures were assessed. Methods: We analysed the HRQoL and clinical severity of patients with HS ( N = 92) treated in 5 Finnish hospitals using HRQoL measurement tools most often used in dermatological clinics, as well as the generic 15D instrument (standardized and self-administered 15-dimensional measure of HRQoL)...

Hidradenitis suppurativa (HS) is a recurrent inflammatory skin disease with a complex etiopathogenesis whose treatment poses a challenge in the clinical practice. Here, we present a novel integrated pipeline produced by the European consortium BATMAN (Biomolecular Analysis for Tailored Medicine in Acne iNversa) aimed at investigating the molecular pathways involved in HS by developing new diagnosis algorithms and building cellular models to pave the way for personalized treatments. The objectives of our european Consortium are the following: (1) identify genetic variants and alterations in biological pathways associated with HS susceptibility, severity and response to treatment; (2) design in vitro two-dimensional epithelial cell and tri-dimensional skin models to unravel the HS molecular mechanisms; and (3) produce holistic health records HHR to complement medical observations by developing a smartphone application to monitor patients remotely...

Down syndrome (DS) has been related to a higher risk of hidradenitis suppurativa (HS). This cross-sectional study assessed DS patients with HS in a Spanish single-centre sample. DS participants presented a lower age of onset, age at diagnosis and time to diagnosis. Also, DS was not associated with the severity of HS measured by baseline IHS4 .

BACKGROUND: Inflammatory markers and leukocyte profiles have not been longitudinally evaluated as objective signs of hidradenitis suppurativa (HS) severity. We sought to assess C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), interleukin-6 (IL-6), and leukocyte profiles as reliable indicators of HS severity. METHODS: Retrospective cohort study of 404 patients seen at the Einstein/Montefiore HS Center, Bronx, New York, between March 2019 and November 2020...

Acne vulgaris and hidradenitis suppurativa (HS) are chronic inflammatory, multifactorial skin disorders that often develop in adolescence and young adulthood. Both acne vulgaris and HS can cause significant morbidity and psychologic distress, with a negative effect on the quality of life. The relationship among diet, acne, and HS remains somewhat controversial; however, there is increasing evidence that high-glycemic diets and consumption of milk and dairy products promote acne. Studies suggest that weight loss through dietary interventions or bariatric surgery and brewer's yeast exclusion diets have the potential to ameliorate the signs of HS...

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition that is more common in females, especially during puberty and menopause. These inflammatory lesions include painful deep-seated nodules and abscesses, draining sinus tracts, and fibrotic scars. This article is a narrative review to explain whole disease aspects, including complication, causes, epidemiology, history, classification, prognosis, comorbidities, the effect of sex hormone, and potent treatments. Most patients with HS, who are not aware of their primary disease, visit primary care physicians to superinfection lesions instead of specialists...

Hidradenitis suppurativa (HS) is a chronic, progressive, debilitating, recurrent inflammatory skin disease characterized by the occurrence of very severe, persistent, painful nodules, abscesses, and fistulas, most commonly found in the skin folds of the axilla, groin, gluteal, and perianal areas. The pathogenesis of HS is still not completely understood; currently, it is considered to be an immune-mediated inflammatory illness (IMID). Due to the significant decrease in the patients' quality of life and a delayed beginning of a treatment, the selection of the appropriate therapy is extremely important in these patients...

Introduction: Hidradenitis suppurativa (HS), once an orphan disease, has gained increased interest world-wide. The most highly cited works in HS are from North America and Europe despite known phenotypic and epidemiological differences globally. Herein, we perform a bibliometric analysis to characterize HS publication trends in Asia and Australasia (AA) over the last decade. Methods: PubMed database was searched to identify HS-related articles and were analyzed for senior authorship, country of origin, article topic, and study design...

Chronic inflammation and dysregulated epithelial differentiation, especially of hair follicle keratinocytes, have been suggested as the major pathogenetic pathways of hidradenitis suppurativa/acne inversa (HS). On the other hand, obesity and metabolic syndrome have additionally been considered as an important risk factor. With adalimumab, a drug has already been approved and numerous other compounds are in advanced-stage clinical studies. A systematic review was conducted to detect and corroborate HS pathogenetic mechanisms at the molecular level and identify HS molecular markers...

Hidradenitis suppurativa (HS) is a painful chronic skin disease characterized by abscesses, nodules, and tunnels in the skin. Adalimumab, a monoclonal antibody against tumor necrosis factor-α, is approved for the treatment of HS in Europe, the USA, and Japan. This multicenter, open-label, post-marketing, observational study (ClinicalTrials.gov: NCT03894956) evaluated the safety and effectiveness of adalimumab in routine clinical practice in Japan (March 2019-May 2021). Patients with HS were treated with s...

INTRODUCTION: Hidradenitis suppurativa (HS) is a chronic, inflammatory, recurrent disease, usually presenting after puberty with inflammatory lesions that mainly affect the apocrine gland-bearing areas of the body, most commonly the axillary, inguinal and anogenital regions. The treatment of HS is associated with certain challenges due to intrinsic resistance to various treatments and the presence of comorbidities and complications. The antibiotic dapsone is an established treatment for HS, but the current evidence base is limited...

Psoriasis and hidradenitis suppurativa (HS) are chronic inflammatory skin diseases that frequently develop in young women. The aim of this study is to evaluate how hidradenitis suppurativa and psoriasis impact women desiring to conceive, and their influence on fertility and gestation. A systematic review of articles dating from January 2015 to April 2021 was performed using the Scopus (Elsevier) database. The search terms were (psoriasis and (birth or pregnancy or fertility)) and ((hidradenitis suppurativa or acne inversa) and (birth or pregnancy or fertility))...

The Coronavirus Disease 2019 (COVID-19) pandemic, a global public health emergency, has changed dermatology practice and daily routine in just under two years. Much has been written in the literature about COVID-19-associated skin manifestations. Nevertheless, much less has been written regarding skin manifestations in patients affected by severe immune-mediated skin diseases, e.g., psoriasis and hidradenitis suppurativa, undergoing biological treatment during the COVID-19 outbreak. Thus, the aim of this article is to provide the reader with an overview of the cutaneous manifestations during the COVID-19 pandemic in this subset of patients...

BACKGROUND: Recurring nodules, abscesses, and lesions characterise hidradenitis suppurativa (HS): a chronic, inflammatory skin disorder. Globally the prevalence of HS is estimated to be around 1% of the population. Leakage, pain, and odour from HS wounds require substantial management. Little is known of the personal burdens that routine wound management imposes on the patient. OBJECTIVES: To evaluate how routine HS wound management impacts patients in terms of the time spent changing dressings, the number of dressings required per day, pain experienced during dressing changes, and negative impact on various domains of their personal lives...

Background   Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition that affects the apocrine gland-bearing areas of the body. It initially presents as painful nodules that eventually develop into abscesses, draining sinuses, and scarring. These manifestations have physical and psychological impacts, which lead to poor quality of life. This study examined the association between quality of life and disease severity, as well as identified the areas of the body most affected by HS among patients in Saudi Arabia...

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by the presence of painful nodules, abscesses, chronically draining fistulas, and scarring in apocrine gland-bearing areas of the body. The exact pathogenesis of HS is not yet well understood, but there is a consensus in considering HS a multifactorial disease with a genetic predisposition, an inflammatory dysregulation, and an influence of environmental modifying factors. Therapeutic approach of HS is challenging due to the wide clinical manifestations of the disease and the complex pathogenesis...
