Diet and physical activity as risk-reducing factors for hidradenitis suppurativa.

Background: Hidradenitis suppurativa (HS) is a multifactorial inflammatory skin disease that is considered to be an immune-mediated inflammatory disease (IMID). Up till now, the impact of lifestyle on (the development of) HS has not been thoroughly investigated.

Objectives: To investigate the effect of dietary intake and physical activity (PA) on (the development of) HS.

Assessment tools and phenotype classification for hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a heterogeneous chronic relapsing skin disease. Several assessment tools are used to assess disease severity and to classify disease phenotype; however, no consensus exists. This review evaluates the various assessment tools and phenotypes, assessing their validity and reliability.

Drug Survival of Oral Retinoids in Hidradenitis Suppurativa: A Real-Life Cohort Study.

Introduction: Cohort studies on the use of retinoids for hidradenitis suppurativa (HS) have yielded contradicting results. As the clinical presentation of HS is heterogeneous, with different predilection sites and hallmark features, it can be hypothesized that HS phenotypes are associated with the effectiveness of specific retinoid treatments.

Objectives: The aim of this study was to evaluate the drug survival of oral retinoids in the treatment of HS and to establish predictors for longer treatment duration.

New insights in hidradenitis suppurativa from a population-based Dutch cohort: prevalence, smoking behaviour, socioeconomic status and comorbidities.

Background: Hidradenitis suppurativa (HS) is a chronic autoinflammatory skin condition and is associated with several comorbidities. Previous studies report variable prevalence rates of HS, depending on the methodology. However, the exact prevalence remains unknown.
