Our goal was to establish the optimal suPAR cut-off point for predicting the need for kidney replacement therapy (KRT) use in sepsis patients and to analyze survival rates based on the suPAR level, AKI diagnosis, and the requirement for KRT. In total, 51 septic patients were included (82% septic shock; 96% mechanically ventilated, 35% KRT). Patients were stratified according to the AKI diagnosis and the need for KRT into three groups: AKI(+)\/KRT(+), AKI(+)\/KRT(\u2212), and AKI(\u2212)\/KRT(\u2212). A control group (N = 20) without sepsis and kidney failure was included. Sepsis patients had higher levels of the suPAR than control (13.01 vs. 4.05 ng\/mL, p &lt; 0.001). On ICU admission, the suPAR level was significantly higher in the AKI(+)\/KRT(+) group than in the AKI(+)\/KRT(\u2212) and AKI(\u2212)\/KRT(\u2212) groups (18.5 vs. 10.6 and 9.5 ng\/mL, respectively; p = 0.001). The optimal suPAR cut-off point for predicting the need for KRT was established at 10.422 ng\/mL (area under the curve 0.801, sensitivity 0.889, specificity 0.636). Moreover, patients AKI(+)\/KRT(+) had the lowest probability of survival compared to patients AKI(+)\/KRT(\u2212) and AKI(\u2212)\/KRT(\u2212) (p = 0.0003). The results indicate that the suPAR measurements may constitute an important element in the diagnosis of a patient with sepsis.<\/jats:p>","DOI":"10.3390\/jcm11061717","type":"journal-article","created":{"date-parts":[[2022,3,20]],"date-time":"2022-03-20T21:30:14Z","timestamp":1647811814000},"page":"1717","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Soluble Urokinase-Type Plasminogen Activator Receptor Levels as a Predictor of Kidney Replacement Therapy in Septic Patients with Acute Kidney Injury: An Observational Study"],"prefix":"10.3390","volume":"11","author":[{"given":"Tomasz","family":"Skalec","sequence":"first","affiliation":[{"name":"Clinical Department of Anaesthesiology and Intensive Therapy, Wroclaw Medical University, Borowska St. 213, 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0541-841X","authenticated-orcid":false,"given":"Barbara","family":"Adamik","sequence":"additional","affiliation":[{"name":"Clinical Department of Anaesthesiology and Intensive Therapy, Wroclaw Medical University, Borowska St. 213, 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0292-4982","authenticated-orcid":false,"given":"Katarzyna","family":"Kobylinska","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics, Informatics and Mechanics, University of Warsaw, Banacha 2, 02-097 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8668-1641","authenticated-orcid":false,"given":"Waldemar","family":"Gozdzik","sequence":"additional","affiliation":[{"name":"Clinical Department of Anaesthesiology and Intensive Therapy, Wroclaw Medical University, Borowska St. 213, 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1038\/nrm2821","article-title":"Regulation of cell signalling by uPAR","volume":"11","author":"Smith","year":"2010","journal-title":"Nat.
