Abstract:
Objective To explore the predictive value of combined detection of serum interleukin-35(IL-35),proprotein convertase subtilisin/kexin type 9(PCSK9),and microRNA-155(miR-155)for sepsis-induced multiple organ dysfunction syndrome(MODS).Methods A total of 170 patients with sepsis admitted in the hospital from June 2020 to June 2023 were selected.Patients were divided into MODS group and non-MODS group according to whether they developed secondary MODS within 28 days.Clinical data and serum levels ofIL-35,PCSK9,and miR-155 were compared between the two groups.Pearson method and partial correlation coefficient were used to analyze the correlation between serum IL-35,PCSK9,and miR-155 and the severity of sepsis and the risk of MODS,and receiver operating characteristics(ROC)curve was used to evaluate the pre-dictive value of serum IL-35,PCSK9,and miR-155 alone and in combination for MODS.In addition,83 patients with sepsis in the hospital from July 2023 to July 2024 were selected as external validation data sets for exter-nal validation.Results Age,percentage of patients with diabetes mellitus,quick sequential organ function as-sessment scale(qSOFA)score,acute physiology and chronic health status evaluation scale Ⅱ(APACHE Ⅱ)score,and serum IL-35,PCSK9,and miR-155 levels in the MODS group were higher than those in the non-MODS group(P＜0.05).Pearson method showed that serum IL-35,PCSK9,and miR-155 were positively cor-related with qSOFA score and APACHE Ⅱ score(P＜0.05).Partial correlation coefficient analysis showed that after excluding other factors,serum IL-35,PCSK9,and miR-155 were still significantly associated with the risk of MODS(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of the combi-nation of serum IL-35,PCSK9,and miR-155 for predicting MODS was 0.907,which was greater than the AUC of each indicator alone.External validation ROC analysis showed that the AUC of combined detection of the three was 0.914.Conclusion The expression of serum IL-35,PCSK9,and miR-155 is significantly associated with the risk of sepsis-induced MODS.Combined detection has certain predictive value for the secondary de-velopment of MODS,and could be used as auxiliary indicators for clinical prediction for MODS,thereby guid-ing clinical prevention and treatment.
