Insights into hidradenitis suppurativa

Area of Science:

• Dermatology
• Immunology
• Genetics

Background:

• Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition impacting approximately 1% of the population.
• It is characterized by painful nodules, abscesses, and sinus tracts, primarily affecting the axillae, inguinal, and gluteal regions.
• HS significantly diminishes patients' quality of life and is linked to various comorbidities.

Purpose of the Study:

• To provide a comprehensive overview of the current understanding of HS.
• To discuss the multifactorial etiology, including genetic, hormonal, and environmental factors.
• To review existing treatment modalities and the ongoing search for more effective therapies.

Main Methods:

• Literature review of HS pathogenesis, clinical presentation, and treatment options.
• Analysis of the interplay between genetic predisposition, hormonal influences, obesity, and smoking.
• Examination of the inflammatory pathways involving IL-1β, IL-17, and TNF.

Main Results:

• HS arises from a hair follicle defect leading to inflammation and fibrosis.
• The disease is associated with immune-mediated, metabolic, cardiovascular, and psychiatric conditions.
• Current treatments, often repurposed, show limited universal efficacy.

Conclusions:

• Effective management of HS requires a combination of medical and surgical approaches.
• Further research into early disease stages is crucial for developing preventative treatments.
• Development of appropriate in vitro and animal models is essential for advancing HS research.
