Abstract:
Objective To investigate the predictive value of serum interleukin-6(IL-6)and procalcitonin(PCT)levels on the prognosis of patients with acute respiratory distress syndrome(ARDS).Methods A total of 99 ARDS patients admitted to Lianyungang Hospital affiliated to Xuzhou Medical University from January 2021 to December 2023 were included in the study.According to the Berlin definition,the patients were divided into mild group(n=22),moderate group(n=42)and severe group(n=35)groups.Based on their 28-day outcomes,they were also divided into survival group(n=65)and death group(n=34).The levels of IL-6 and PCT in each group were compared.The predictive value of IL-6 and PCT for the prognosis of ARDS patients was analyzed using receiver operat-ing characteristic(ROC)curve and the area under the curve(AUC).The Kaplan-Meier method was used to plot survival curves for ARDS patients with different levels of IL-6 and PCT.Results Among the three groups with varying severity of ARDS,the severe group had the highest IL-6 and PCT levels,followed by the moderate group,and the mild group had the lowest levels.The differences among the groups were statistically significant(P<0.05).The levels of IL-6 and PCT in the death group were significantly higher than those in the survival group,and the difference was statistically significant(P<0.05).The AUC of IL-6 and PCT in predicting the prognosis of ARDS patients were 0.793 and 0.776,with the sensitivity of 79.4%and 94.1%,and the specificity of 70.8%and 61.5%,respective-ly.Kaplan-Meier survival curve analysis showed that when IL-6 was ≥110.700pg/ml and PCT was ≥ 1.700ng/ml,the 28-day sur-vival rate of ARDS patients was significantly lower than that of patients with IL-6<110.700pg/ml and PCT<1.700ng/ml(P<0.001).Conclusion PCT and IL-6 levels have good value in predicting the short-term prognosis of ARDS patients,and can be used as effective indicators for prognosis evaluation in ARDS patients.
