HS is often challenging to treat. In this review, we discuss the unique characteristics of HS in four special populations: children, the elderly, pregnant individuals, and breastfeeding mothers. In children, diagnosis may be delayed due to atypical and early HS disease presentations. HS management plans must take into consideration the lack of rigorous efficacy and safety data of HS treatments in this population. However, it is important to weigh the risk of treatments against the risk of untreated HS and the morbidity and mortality risk that having HS confers. Pregnancy poses unique challenges for women with HS, with their condition possibly worsening during pregnancy and increased risk of fetal death. Management strategies during pregnancy must consider both maternal and fetal safety. Similarly, breastfeeding mothers require thoughtful medication selection to balance symptom management with infant safety. In the elderly, HS may present more severely and is often complicated by comorbidities. Treating HS in this population should safely accommodate patients' additional health conditions. Furthermore, this review highlights the overall paucity of primary literature addressing management in these populations, underscoring the need for further research to optimize HS care across all stages of life.</p>","PeriodicalId":11186,"journal":{"name":"Dermatology and Therapy","volume":" ","pages":"2407-2425"},"PeriodicalIF":3.5,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11393272/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142125127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated the long-term safety of risankizumab in psoriatic disease.</p><p><strong>Methods: </strong>Long-term safety was evaluated by analysing data from 20 (phase 1-4) clinical trials for plaque PsO and four (phase 2-3) trials for PsA. Treatment-emergent adverse events (TEAEs) and AEs in areas of special interest were reported among patients receiving ≥ 1 dose of risankizumab. Exposure-adjusted event rates were presented as events (E) per 100 patient-years (PY).</p><p><strong>Results: </strong>The long-term safety data analyses included 3658 patients with PsO (13,329.3 PY) and 1542 patients with PsA (3803.0 PY). The median (range) treatment duration for patients with PsO and PsA was 4.1 (0.2-8.8) years and 2.8 (0.2-4.0) years, respectively. In the PsO population, rates of TEAEs, serious AEs and AEs leading to discontinuation were 145.5 E/100 PY, 7.4 E/100 PY and 1.9 E/100 PY, respectively; in the PsA population, these rates were 142.6 E/100 PY, 8.6 E/100 PY, and 1.8 E/100 PY, respectively. The rates of serious infections (excluding COVID-19-related infections) in the PsO and PsA populations were 1.2 and 1.4 E/100 PY, respectively. The rates of opportunistic infections (excluding tuberculosis and herpes zoster) were low (< 0.1 E/100 PY) in both populations. The rates of both nonmelanoma skin cancer (NMSC) and malignant tumours excluding NMSC were 0.6 and 0.5 E/100 PY in PsO and PsA, respectively, which are within the benchmarks of prior epidemiological studies. Adjudicated major cardiovascular event rates were 0.5 E/100 PY in PsO and 0.3 E/100 PY in PsA, which are within the epidemiologic reference benchmarks for both indications. No additional safety concerns were identified with this long-term exposure.</p><p><strong>Conclusions: </strong>The results support the favourable safety profile of risankizumab for long-term treatment of psoriatic disease with no new safety concerns and similar safety profiles among both PsO and PsA populations.</p>","PeriodicalId":11186,"journal":{"name":"Dermatology and Therapy","volume":" ","pages":"2523-2538"},"PeriodicalIF":3.5,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11393270/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141995483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
