However, there is a lack of comprehensive evaluations that consider a variety of clinical and demographic factors, and the risk of developing HS in PSO patients remains unclear. Our study aims to examine HS risk over time among PSO patients versus matched controls while considering the influence of confounders to provide insights into the potential link between these two diseases. Method: In this multi-institutional cohort study using the TriNetX database, we matched 202,318 patients with PSO with an equivalent number of individuals without PSO, using propensity score matching. The study period extended from 1 January 2005 to 31 December 2018. We computed hazard ratios and their respective 95% confidence intervals (CIs) to evaluate the probability of HS manifestation over a period of 5 years in patients with PSO in comparison to those without PSO. Results: PSO patients demonstrated a consistently higher risk of developing HS than matched controls across all analytic models with the hazard ratios (HR) ranging from 1.43 (95% CI 1.30\u20131.56) to 5.91 (95% CI 2.49\u201314.04). Stratified analyses showed the increased HS risk was observed in both genders but only significant in those aged 18\u201364 years. Kaplan\u2013Meier analysis indicated PSO patients had a higher cumulative probability of developing HS over time (HR 1.77, 95% CI 1.49\u20131.89). Conclusions: PSO was associated with increased HS risk, highlighting the importance of considering HS as a potential comorbidity in PSO patients and may have implications for early detection, prevention, and management strategies for both conditions. Shared inflammatory pathways, genetic components, and skin dysbiosis may contribute. Further research should elucidate underlying mechanisms.<\/jats:p>","DOI":"10.3390\/life14060730","type":"journal-article","created":{"date-parts":[[2024,6,6]],"date-time":"2024-06-06T08:45:37Z","timestamp":1717663537000},"page":"730","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["New-Onset Hidradenitis Suppurativa in Psoriasis Patients: A Multi-Center, Retrospective Cohort Study"],"prefix":"10.3390","volume":"14","author":[{"given":"Chen-Pi","family":"Li","sequence":"first","affiliation":[{"name":"Department of Nursing, Tungs\u2019 Taichung MetroHarbor Hospital, Taichung 435403, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-7027-3132","authenticated-orcid":false,"given":"Shao-Wei","family":"Lo","sequence":"additional","affiliation":[{"name":"Education Center, National Cheng Kung University Hospital, College of Medicine, National Cheng Kung University, Tainan 701, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9556-8907","authenticated-orcid":false,"given":"Ru-Yin","family":"Tsai","sequence":"additional","affiliation":[{"name":"Department of Anatomy, School of Medicine, Chung Shan Medical University, Taichung 40201, Taiwan"},{"name":"Department of Medical Education, Chung Shan Medical University Hospital, Taichung 40201, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hui-Chin","family":"Chang","sequence":"additional","affiliation":[{"name":"Evidence-Based Medicine Center, Chung Shan Medical University Hospital, Taichung 40201, Taiwan"},{"name":"Library, Chung Shan Medical University Hospital, Taichung 40201, Taiwan"},{"name":"School of Medicine, Chung Shan Medical University, Taichung 40201, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8897-5635","authenticated-orcid":false,"given":"Shuo-Yan","family":"Gau","sequence":"additional","affiliation":[{"name":"School of Medicine, Chung Shan Medical University, Taichung 40201, Taiwan"},{"name":"Department of Medical Education, Kaohsiung Chang Gung Memorial Hospital, Kaohsiung 833, Taiwan"},{"name":"Orthopedics Department, Chi-Mei Medical Center, Tainan 71004, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"377","DOI":"10.1038\/jid.2012.339","article-title":"Global epidemiology of psoriasis: A systematic review of incidence and prevalence","volume":"133","author":"Parisi","year":"2013","journal-title":"J.
