Summary

The pathogenesis of HS is still poorly understood: the pilosebaceous tropism and the fact that patients respond to combinations of antibiotics and/or immunosuppressive treatments suggest the involvement of 3 factors that would be intimately linked: the presence of (i) a microbial dysbiosis, (ii) a dysfunction of the pilosebaceous apparatus and (iii) an inappropriate immune response. But how these 3 elements interact with each other remains unestablished, with few studies that have analyzed them from a kinetic point of view. Beyond a possible dysfunction of the pilosebaceous apparatus, we hypothesize a bacterial dysbiosis in connection with abnormalities of autophagy function with secondary development of an inappropriate immune response. Because of its functions of bacterial clearance and activation of local immune response, a defect in the autophagic process may be associated with the development of inflammatory pathologies related to microbial dysbiosis. Crohn's disease (CD), an inflammatory pathology of the gastrointestinal tract associated with intestinal dysbiosis, has been associated with alterations in autophagy, with approximately 50% of patients having single nucleotide polymorphisms (SNPs) associated with autophagy deficiency (Ellinghaus et al., 2013). The epidemiological association of CD/HS, the presence of skin dysbiosis and a chronic inflammatory response during HS, make us suspect a deficit of autophagic function in these patients, in a similar way to what is observed during Crohn's disease.

The aim of this study is to analyze the frequency of 100 SNPs, reported to be associated with autophagy deficiency, in a cohort of moderate-to-severe HS patients.
