Hidradenitis suppurativa (HS) is a chronic inflammatory disease manifesting in inverse body regions. In a systematic review, the role of hormones in HS will be presented to better understand the pathomechanisms of HS. The review is based on the PRISMA criteria. Systematic research was carried out using keywords. Subsequently, the data were analyzed based on the clinical response and other relevant information. The main focus of our systematic review was on HS manifestation, exacerbation, sex hormones, antiandrogen therapy, thyroid function, polycystic ovary syndrome, insulin resistance, and adipokines. In HS, there appears to be a dysregulated adipokine release that is shifted towards pro-inflammatory adipokines. Insulin resistance is significantly more common in HS than in healthy patients regardless of BMI, age, and gender. Insulin resistance in HS patients leads to further cardiovascular disease. The mechanism of insulin resistance and role of adipokines should be investigated in future studies to better provide the pathomechanisms of HS. The role of androgens seems to be important in a certain subgroup of female patients. Anti-androgenic therapy can be useful and helpful in some patients. However, further studies are needed to better understand the hormonal relationship in HS.

Background: Vogt–Koyanagi–Harada disease (VKHD)-like symptoms have previously been reported in 11 melanoma patients treated with immune checkpoint inhibitors. Materials & methods: We report a female patient with multilocular metastatic melanoma who was treated with nivolumab. Results: Following the first nivolumab dose, she experienced bilateral blurry vision, hearing loss, vertigo and ataxia. Ocular ultrasound was consistent with the diagnosis of uveitis. Audiography revealed severe bilateral sensorineural hearing loss. A high-dose corticosteroid regimen was initiated under which the patient developed generalized vitiligo. Abdominal and thoracic CT scans showed an almost complete response to nivolumab therapy. This patient fulfilled all criteria of VKHD which is characterized pathogenetically by an antimelanocytic autoimmune process. Conclusion: The present case showed an impressive response to antimelanoma immunotherapy. Based on these data, the occurrence of VKHD in melanoma patients appears to be a strong indicator for immune checkpoint inhibitor efficacy.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease presenting with recurrent inflammatory lesions in intertriginous body regions. HS has a pronounced impact on patients’ quality of life and is associated with a variety of comorbidities. Treatment of HS is often complex, requiring an individual approach with medical and surgical treatments available. However, especially in moderate-to-severe HS, there is an urgent need for new treatment approaches. In recent years, increased research has led to the identification of new potential therapeutic targets. This review aims to give a comprehensive and practical overview of current treatment options for HS. Furthermore, the clinically most advanced novel treatment approaches will be discussed.
