Abstract:
Objective:To explore relationship between early fluid balance and phenotypic changes of Treg in patients with sep-sis in ICU and its influence on prognosis.Methods:Ninety-eight patients with sepsis admitted to Wuxi Fifth People's Hospital from June 2018 to June 2023 were selected as study objects,and divided into death group(n=34)and survival group(n=64)according to whether patients died within 28 days after admission to ICU.Clinical data,fluid balance,CD4+CD25+Foxp3+Treg and CD4+CD25+Treg levels after 24 h and 72 h in ICU were compared between two groups.Multivariate Logistic regression was used to analyze correlation between fluid balance and CD4+CD25+Foxp3+Treg and CD4+CD25+Treg.Influencing factors of death in patients with sepsis in ICU were screened and corresponding prediction model was established.Results:Age,sequential organ failure assessment(SOFA)score,acute physiology and chronic health evaluation(APACHE Ⅱ)score,fluid balance 24 h and 72 h after ICU admission,CD4+CD25+Foxp3+Treg and CD4+CD25+Treg levels were significantly higher than survival group(P<0.05).Multivariate Logistic regres-sion analysis showed that age,SOFA score,APACHE Ⅱ score,fluid balance at 24 h and 72 h after ICU admission,CD4+CD25+Foxp3+Treg and CD4+CD25+Treg levels at 24 h after ICU admission were all risk factors for death at 28 days after ICU admission(P<0.05).Combined with the above five factors to build a predictive model with high sensitivity and accuracy.Conclusion:Higher fluid balance and CD4+CD25+Foxp3+Treg and CD4+CD25+Treg levels are risk factors for death in patients with sepsis in ICU,and they are significantly positively correlated.
