Presepsin, calprotectin, and interleukin-6 levels were measured in both groups and subjected to statistical analyses.</p><p><strong>Results: </strong>To ensure equality between the two groups participating in the study, 17 female and 28 male patients were included in each group. The presepsin, calprotectin, and interleukin-6 levels of the patients with appendicitis were significantly higher than those of the healthy group (<i>p</i> < 0.001 for all). However, presepsin, calprotectin, and interleukin-6 were not significant parameters in differentiating between complicated and uncomplicated appendicitis (<i>p</i> = 0.493, <i>p</i> = 0.202, and <i>p</i> = 0.448, respectively).</p><p><strong>Conclusion: </strong>Presepsin, calprotectin, and interleukin-6 levels may be useful in diagnosing acute appendicitis but would be insufficient in identifying complicated cases.</p>","PeriodicalId":8921,"journal":{"name":"Biomarkers","volume":" ","pages":"479-484"},"PeriodicalIF":4.6,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142406000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
