[Clinical significance of combined sST2 and NT-proBNP detection for the short-term prognosis of acute organophosphorus pesticide poisoning].

Objective: To explore the value of soluble growth stimulation expression gene 2 protein (soluble suppression of tumorigenicity 2; sST2) and N terminal B type brain natriuretic peptide (N-terminal probrainnatriuretic peptide, NT-proBNP) in evaluating the short-term prognosis of acute organophosphorus pesticide poisoning. Methods: select 228 patients with acute organophosphorus pesticide poisoning in our hospital from October 2017 to March 2020. According to the grade of poisoning degree, it was divided into 82 cases in mild and moderate group and 146 cases in severe group. hs-cTnI、CK-MB、sST2、NT-proBNP、APACHE Ⅱ score and cholinesterase activity were detected 4 h、12 h、24 h after admission. ROC curve was used to evaluate sST2 and NT-proBNP to predict the prognosis of AOPP. Results: 4 hours after admission, there was no significant difference in the scores of hs-cTnI, APACHE Ⅱ, cholinesterase and CK-MB between the Severe Group and the mild and moderate Group (P<0.05) . At 12 and 24 hours after admission, the scores of hs-cTnI, CK-MB and APACHE Ⅱ in severe group were higher than those in mild and moderate group, and the changes of Cholinesterase were more significant than those in 12 hours after Admission (P<0.05) . 4 hours after admission, SST2 and NT-proBNP levels were significantly higher in severe group than those in mild and moderate Group (P<0.05) . The level of SST2 and NT-proBNP in the severe group was significantly higher than that in the mild and moderate group 12 and 24 hours after Admission (P<0.01) , and the level of SST2 and NT-proBNP was significantly higher than that in the mild group 12 hours after Admission (P<0.05) . Correlation analysis showed that 24 hours after admission, sST2, NT-proBNP were positively correlated with APACHE-Ⅱ scores (R=0.634, 0.723, P<0.01) . The area under sST2 combined with NT-proBNP was 0.891, higher than that under sST2 and NT-proBNP at 12 h after admission. The 24 h APACHE Ⅱ score after admission area under the curve was 0.838. Conclusion: sST2 and NT-proBNP combined detection can early predict the occurrence of recent complications in AOPP patients.
