Proceedings Report of the Fifth Symposium on Hidradenitis Suppurativa Advances (SHSA) 2020.

The Symposium on Hidradenitis Suppurativa Advances (SHSA) is a joint meeting of the United States Hidradenitis Suppurativa Foundation (HSF) and the Canadian Hidradenitis Suppurativa Foundation (CHSF). This annual cross-disciplinary meeting brings together experts from around the world in an opportunity to discuss the most recent advances in the study of hidradenitis suppurativa (HS). The fifth annual meeting was held virtually on 9-11 October 2020. A record 347 attendees, including 79 people with HS, from 20 different countries attended. Key take-home points included: Clinicians can optimize each visit by listening, provide education, and discuss treatments; a patient decision aid for HS (HS-PDA) is a freely available tool (www.informed-decisions.org); COVID-19 severity in HS patients was not different for patients treated with/without a biologic; comorbidity screening recommendations will be published soon; neutrophil extracellular traps (NETs) may play a role in HS; memory B cells, T helper 1 cytokines, and interleukin 1 signaling contributes to HS pathogenesis and are targets for new therapies; novel therapies are showing promise including a new JAK1 inhibitor (INCB054707) and brodalumab; and HS-specific outcome measures have emerged to better monitor disease severity, flare, and progression including a patient reported measure (HiSQOL) and an HS-specific investigator global assessment.

Remote consultations for patients with hidradenitis suppurativa during the COVID-19 pandemic: a single-centre experience.

Remote dermatology consultations largely superseded face-to-face (FTF) consultations during the peak of the COVID-19 pandemic in the UK. Remote examination of patients with hidradenitis suppurativa (HS) brings particular challenges, given the propensity of HS to affect intimate body areas. To understand the impact of remote consultations on the care of patients with HS, a retrospective analysis was conducted of all consultations from 2 April to 29 October 2020 at the HS clinic at Imperial College Healthcare NHS Trust. In this group of patients with HS, 46.3% were black, compared with 7.0% of patients attending general dermatology clinics (P < 0.001). The majority (65.9%) of patients had previously received or were currently taking adalimumab. All consultations were performed by telephone and in 50.7% of the consultations, patients were assessed as having unstable (u)HS, with 81.1% of these uHS episodes leading to a change in pharmacological therapy. The decision-making process was aided by patient-submitted photographs at only 8.1% of consultations involving uHS, for reasons of patient privacy, comfort and data security. The data suggest that HS is an inherently unstable disease despite maximal medical therapy, and this study highlights important reasons for the assessment of patients with HS by FTF consultations where safely possible.

The most recent advances in understanding and managing hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a chronic, inflammatory, recurrent, and debilitating skin disease of the hair follicle unit that typically develops after puberty. HS has a significant negative impact on both the quality of life (QOL) of patients affected by this disease as well as family members and caregivers. However, the pathogenesis of HS is multifactorial and still remains to be fully elucidated, which makes the development of treatments difficult. The last 10 years have seen a surge in HS research, and many new findings have come to light, yet much more remains to be elucidated. Physicians must employ a multidisciplinary approach to maximally address all facets of HS. Clinical characteristics of the disease that differ between females and males as well as across different races and ethnic groups must be considered. Targeted topical, oral, and injectable therapies continue to be developed for HS as a greater understanding of the pathogenesis is reached. However, randomized controlled trials regarding dietary factors that may contribute to HS are needed to meet our patients' growing concerns and questions about the role of diet in HS pathogenesis. Finally, improved outcome measures are needed to standardize HS severity and grading between physicians and clinical trials, and a more diverse representation of HS populations is needed in clinical trials.

Management of patients with hidradenitis suppurativa during the COVID-19 pandemic: Risk and benefit of immunomodulatory therapy.

Coronavirus disease 2019 (COVID-19) is a clinical syndrome caused by a new coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Italy has been the first nation affected by the coronavirus pandemic and is the second in the number of reported deaths in the European Union. In the United Hospital of Ancona, a specialist outpatient clinic dealing with diagnosis and treatment of immunomediated skin diseases has been operating since 1985, and 291 patients with hidradenitis suppurativa (HS) are currently being treated. Several cutaneous immunomediated diseases, including HS, are treated with biologic and nonbiologic immunosuppressive and immunomodulatory drugs. Since the end of February 2020, when the SARS-CoV-2 pandemic had already spread in most of Italy, a task force comprised of seven specialists has been set up with the aim of addressing problems relating to the specific risk for this class of patients in relation to SARS-CoV-2 infection and immunosuppressive ongoing therapy. In this article, the management of HS disease during the COVID-19 pandemic is discussed. The main goal was to evaluate the risk/benefit in modulating treatment taking into consideration patients' risk of exposure to SARS-CoV-2 virus.
