Summary

This study examined skin samples from 15 people with hidradenitis suppurativa (HS) and 15 healthy volunteers to measure certain genes and proteins linked to inflammation. The goal was to better understand what causes HS and find possible markers of disease severity. No treatment was given; it was purely an observational study to gather knowledge.

Who is studied

The study population consists of adult patients aged 18 years and older with a clinical and/or histopathological diagnosis of hidradenitis suppurativa, as well as healthy control individuals aged 18 years and older without autoimmune or inflammatory disease. Healthy controls were selected to be similar to the hidradenitis suppurativa group in terms of age, sex, and metabolic characteristics. Control participants were recruited among individuals presenting for benign nevus excision at the Trakya University Medical Faculty Department of Dermatology.
