Global Hidradenitis Suppurativa COVID-19 Registry: A Registry to Inform Data-Driven Management Practices.

Br J Dermatol 2020 Jun 29. Epub 2020 Jun 29.

Patientforeningen HS, Copenhagen, Denmark.

The management of hidradenitis suppurativa (HS), a chronic inflammatory skin disease, deserves special consideration in the context of the Coronavirus 2019 (COVID-19) pandemic. A new Global Hidradenitis Suppurativa COVID-19 Registry has been developed to capture data on risks, clinical course, and outcomes of COVID-19 in HS patients. Caused by the virus SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2), COVID-19 is an easily transmissible disease which, in its most severe form, is characterized by respiratory failure and multiple organ dysfunction triggered by a cytokine storm response that predominates in older adults and those with significant comorbidities.

Spironolactone is an economical potassium-sparing diuretic with an anti-androgenic effect and a good safety profile. Our experience suggests that this diuretic is underexploited in dermatology even though there is evidence supporting its use in several skin conditions. When prescribed for acne in female patients (level 1-2 evidence; strength of recommendation, B), for example, it can reduce the need for antibiotics and possibly isotretinoin. Read More

Veracity Clinical Research, Suite 18 Level 1 250 Ipswich Rd., Woolloongabba QLD 4102, Australia.

Hidradenitis suppurativa (HS), also known as acne inversa, is a chronic, relapsing inflammatory skin condition characterised by the presence of painful nodules, abscesses, and sinus tracts or scarring. Affecting up to 4% of the population, it is not uncommon and is seen predominantly in females at a ratio of 3 : 1. HS carries a substantial burden for those who suffer from it, from the significant psychosocial impact, to the cost of the multitude of topical and systemic treatments which often do not successfully control its symptoms.

Pleiotropic Role of Notch Signaling in Human Skin Diseases.

Int J Mol Sci 2020 Jun 13;21(12). Epub 2020 Jun 13.

Institute for Maternal and Child Health-IRCCS "Burlo Garofolo", 34137 Trieste, Italy.

Notch signaling orchestrates the regulation of cell proliferation, differentiation, migration and apoptosis of epidermal cells by strictly interacting with other cellular pathways. Any disruption of Notch signaling, either due to direct mutations or to an aberrant regulation of genes involved in the signaling route, might lead to both hyper- or hypo-activation of Notch signaling molecules and of target genes, ultimately inducing the onset of skin diseases. The mechanisms through which Notch contributes to the pathogenesis of skin diseases are multiple and still not fully understood. Read More

Dermatology Unit, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Department of Physiopathology and Transplantation, Università degli Studi di Milano Via Pace 9, Milan, Italy; Department of Pathophysiology and Transplantation, Università degli Studi di Milano, Milan, Italy. Electronic address:

Background: Diagnosis of pyoderma gangrenosum, acne and hidradenitis suppurativa (PASH) and pyogenic arthritis, pyoderma gangrenosum, acne, and hidradenitis suppurativa (PAPASH) patients, in spite of recently identified genetic variations, is just clinical, since most patients do not share the same mutations, and the mutations themselves are not informative of the biological pathways commonly disrupted in these patients.

Objective: To reveal genetic changes more closely related to PASH and PAPASH etiopathogenesis, identifying novel common pathways involved in these diseases.

Methods: Cohort study on PASH (n = 4) and PAPASH (n = 1) patients conducted using whole exome sequencing (WES) approach and a novel bioinformatic pipeline aimed at discovering potentially candidate genes selected from density mutations and involved in pathways relevant to the disease. Read More

MABp1 targeting interleukin-1alpha in hidradenitis suppurativa non-eligible for adalimumab treatment: Results of the open-label extension period.

Clin Exp Dermatol 2020 Jun 9. Epub 2020 Jun 9.

4th Department of Internal Medicine, National and Kapodistrian University of Athens, Athens, Greece.

The emerging situation of patients with moderate-to-severe hidradenitis suppurativa (HS) non-eligible for or not responding to adalimumab generates the unmet need for new therapies. In a previous small-scale randomized clinical trial, MABp1 (also known as bermekimab) showed 60% treatment efficacy compared to 10% of placebo in such patient population. Eight of patients originally randomized to placebo treatment were allowed to participate in an open-label extension (OLE) treatment with MABp1 7. Read More

Proposed Definitions of Typical Lesions in Hidradenitis Suppurativa.

Dermatology 2020 Jun 9:1-8. Epub 2020 Jun 9.

Private practice, Paris, France.

Background: Although not rare, hidradenitis suppurativa (HS) is often under-recognized by physicians. The diagnosis of HS is clinical via the recognition of lesions typical of the disease, but universally accepted definitions of these latter are currently lacking, which means that certain severity scores employed for HS classification/management are used differently by different physicians. Our aim was to develop a set of descriptive definitions and associated images of HS lesions, in order to enable doctors to better recognize and evaluate the disease. Read More

Pyoderma gangrenosum and suppurative hidradenitis association, overlap or spectrum of the same disease? Case report and discussion.

Exp Ther Med 2020 Jul 30;20(1):38-41. Epub 2019 Oct 30.

Department of Pathology, Colentina Clinical Hospital, 020125 Bucharest, Romania.

Suppurative hidradenitis and pyoderma gangrenosum are rare disorders that can be seen isolated or even more rare, as part of different autoinflammatory syndromes: Pyoderma gangrenosum, acne, and hidradenitis suppurativa (PASH), pyoderma gangrenosum, acne, pyogenic arthritis, and hidradenitis suppurativa (PAPASH) or psoriatic arthritis, pyoderma gangrenosum, acne, and hidradenitis suppurativa (PsAPASH). Although they have different clinical features, suppurative hidradenitis and pyoderma gangrenosum seem to share similar pathogenic pathways involving a dysregulated innate immune system, with neutrophilic inflammation, mediated by IL-1β, controlled by NALP3 inflammasome pathway. We report a case of a 53-year-old male patient previously diagnosed with HS in inguinal-scrotal area that developed rapidly after a traumatic injury on his left anterior calf, a painful inflammatory plaque with pustules on the surface that rapidly progressed (24-48 h) to form ulcers.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition, clinically characterized by boiled cysts, comedones, abscesses, hypertrophic scars, and/or sinus tracts typically in the apocrine-gland-rich areas such as the axillae, groin, and/or buttocks. Although its precise pathogenic mechanisms remain unknown, I herein emphasize the importance of the following three recent discoveries in the pathogenesis of HS: First, heterozygous loss-of-function mutations in the genes encoding γ-secretase, including , and , have been identified in some patients with HS. Such genetic alterations result in hyperkeratosis, dysregulated hair follicle differentiation, and cyst formation via aberrant Notch signaling. Read More

Mannose-binding lectin (MBL) deficiency is associated with recurrent infections, autoimmune and inflammatory skin disease, and vascular complications. MBL deficiency is not a recognized comorbidity in hidradenitis suppurativa (HS); the latter is associated with the group of autoinflammatory disorders. A 32-year-old woman presented with a history of recurrent painful, deep-seated abscesses and pustular lesions since the age of 13 years. Read More

Aim Of The Study: Hidradenitis suppurativa (HS) and psoriasis vulgaris (PSO) are chronic inflammatory dermatoses in which proinflammatory cytokines, such as IL-17, play a central role. The prevalence of keratoconjunctivitis sicca (KCS) is commonly higher in PSO than in healthy individuals. This study was thus set up to investigate the prevalence of KCS among patients with HS.
