Hidradenitis suppurativa (HS) is a chronic, recurrent inflammatory skin disease that affects hair follicle-bearing areas, particularly the axillae, groin, and anogenital regions. The exact pathogenesis of HS is not fully understood, but a combination of genetic, hormonal, and environmental factors are believed to contribute to its development.
Currently, the prevailing theory is that HS is caused by an interaction between androgens, which are male hormones that are also present in females, and the anaerobic bacteria found in hair follicles. This interaction leads to follicular occlusion and the formation of microcomedones, which then become inflamed and eventually lead to the characteristic nodules, abscesses, and tunnels of HS.
Studies have shown that genetic predisposition plays a role in the development of HS. For example, genetic mutations in the genes involved in the immune response and inflammation have been identified in patients with HS. In addition, hormonal imbalances, particularly those associated with androgen excess, have also been implicated in the development of HS.
Despite ongoing research, there is still much that is unknown about the pathogenesis of HS. However, there has been significant progress in our understanding of the disease in recent years, and new therapeutic approaches, such as biologic drugs, are being developed to treat the condition. Currently, the best treatment approach for HS is multidisciplinary, and may include a combination of medical and surgical treatments, as well as lifestyle changes, to manage symptoms and improve quality of life for patients.
