Validated, inclusive and easy-to-use outcomes for hidradenitis suppurativa are essential both in the clinical trial setting practice. The continuous IHS4 is a validated tool that dynamically assesses nodules/abscesses/draining tunnels classifies disease severity as mild/moderate/severe. However, dichotomous often required trials reporting.To develop validate outcome based on can be used settings day-to-day practice.De-identified data from PIONEER-I -II studies were accessed through Vivli....

Hidradenitis suppurativa (HS) is a common and severely morbid chronic inflammatory skin disease that reported to be highly heritable. However, the genetic understanding of HS insufficient, limited genome-wide association studies (GWASs) have been performed for HS, which not identified significant risk loci.

Patients with Down syndrome (DS) have increased incidence of inflammatory conditions, including hidradenitis suppurativa (HS), which may require biologic medications for optimal disease management. This retrospective cohort study evaluated 27 patients DS and co-morbid HS demonstrated that biologics are well tolerated effective in this cohort.

Importance Various surgical approaches for hidradenitis suppurativa (HS) have been described in the literature, but nomenclature is inconsistent. Excisions as wide, local, radical, and regional with variable descriptions of margins. Deroofing procedures various though approach are generally more uniform. No international consensus has formed to globally standardize terminology HS procedures. Lack such agreement may contribute misunderstanding or misclassification procedural research studies...

Background: Previously, a new dichotomous outcome was developed, calculated as 55% reduction in the International Hidradenitis Suppurativa 4 (IHS4-55) score. It validated datasets of adalimumab and placebo-treated HS patients. External validation is an important aspect clinical outcomes. Objectives: We aimed to externally validate novel IHS4-55 non-biologic treated dataset Methods: Data from previously published European-wide prospective study antibiotic treatment patients were used assess...
