Objective:To explore the predictive value of MB isoenzyme of creatine kinase (CK-MB) and poisoning severity score (PSS) in the clinical prognosis of patients with wasp sting.Methods:A retrospective study was conducted. The clinical data of patients who were stung by wasps admitted to emergency department of the First Affiliated Hospital of Henan University of Science and Technology from July 2017 to November 2019 were collected. The 24-hour acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), CK-MB and PSS scores of the patients were collected after admission, and 28-day outcome was recorded. Spearman correlation analysis method was used to analyze the correlation between CK-MB and PSS score. Logistic regression model was used to construct joint predictors, and the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of various indicators for 28-day prognosis of patients with wasp stings.Results:Finally 90 patients were included in the analysis. There were 67 patients survived at 28 days, and 23 dead with the 28-day mortality of 25.6%. APACHEⅡ score, CK-MB and PSS score in the death group were significantly higher than those in the survival group [APACHEⅡscore: 19.7±2.7 vs. 13.7±2.3, CK-MB (U/L): 183 (151, 243) vs. 36 (21, 75), PSS score: 17.7±2.6 vs. 9.3±4.5, all P < 0.01]. The correlation analysis showed that CK-MB and PSS score were positively correlated ( r = 0.843, P < 0.01). Logistic regression model fitted CK-MB and PSS score, and Hosmer-Lemeshow test showed that the model fitted well. ROC curve analysis showed that the area under ROC curve (AUC) of CK-MB for predicting 28-day outcome was 0.957, the sensitivity was 91.3%, and the specificity was 88.1%; the AUC of PSS score was 0.908, the sensitivity was 91.3%, and the specificity was 90.8%. The AUC of CK-MB combined with PSS score was 0.964, the sensitivity was 100%, and the specificity was 79.4%, indicating that CK-MB combined with PSS score had higher predictive value and higher sensitivity for 28-day prognosis of patients with wasp sting. Conclusions:High CK-MB level and high PSS score in early stage of wasp sting injury indicate poor prognosis. Both CK-MB and PSS score can be used as predictors for predicting the prognosis of patients with wasp stings. In addition, CK-MB combined with PSS score have greater predictive value .
