Moreover, Gal-3 and IL-6 were identified as having predictive value for mortality in hospitalized patients, while both IL-6 and TNF-α demonstrated diagnostic accuracy across all patient groups.</p><p><strong>Conclusions: </strong>The study results indicate that the levels of IL-6 TNF-α play a crucial role in determining the hospitalization and mortality of COVID-19 patients. Additionally, it was observed that Gal-3 and IL-6 levels can be utilized to assess the severity of the disease and predict mortality in patients who require hospitalization.</p>","PeriodicalId":49160,"journal":{"name":"Journal of Infection in Developing Countries","volume":"18 9.1","pages":"S33-S39"},"PeriodicalIF":1.4,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142583664","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}
