Abstract:
Objective To explore the correlation between the expression level of serum peptidylarginine deiminase type 2(PAD2)and acute physiology and chronic health evaluationⅡ(APACHE Ⅱ)scores in patients with septic shock.Methods A total of 103 patients with septic shock admitted to the First People's Hospital of Neijiang from June 2020 to June 22 were regarded as the study group.According to the severity of the condition,the APACHE Ⅱ scores were used to classify study group into mild group(n=39),moderate group(n=51)and severe group(n=13).In addition,103 healthy individuals who underwent physical examination in the hospital during the same period,whose general information matched the study group patients,were selected as the control group.Serum PAD2 expression level in patients with septic shock was determined by enzyme-linked immunosorbent assay.Spearman method was applied to analyze the correlation between serum PAD2 expression level and APACHE Ⅱ scores in patients with septic shock.Logistic regression was applied to analyze the factors affecting the severity of patients with septic shock.The diagnostic value of serum PAD2 in moderate and severe septic shock was evaluated using receiver operating characteristic(ROC)curve analysis.Results The differences in blood creatinine levels(137.52±9.01μmol/L vs 112.22±8.67μmol/L)and platelet counts(74.58±5.19 vs 86.02±5.34)×109/L between study group and control group were statistically significant(t=20.535,15.591,all P<0.05).The expression level of PAD2 in the study group(42.47±6.62 ng/ml)was higher than that in the control group(38.59±5.31 ng/ml),with significant difference(t=4.815,P<0.05).The expression level of serum PAD2 and APACHE Ⅱ scores in patients with septic shock gradually increased with the severity of the condition(F=3.777,176.582,all P<0.05).The expression level of serum PAD2 in patients with septic shock was positively correlated with APACHE Ⅱ scores(r=0.859,P<0.05).Serum creatinine(OR=1.927),PAD2(OR=1.803)and APACHE Ⅱscores(OR=1.657)were risk factors for moderate and severe septic shock(P<0.05),while platelet count(OR=0.781)was a protective factor(P<0.05).The area under the curve(AUC)of serum PAD2 in the diagnosis of moderate and severe septic shock was 0.880,and the sensitivity and specificity were 75.73%(95%CI:0.701～0.826)and 90.29%(95%CI:0.851～0.935),respectively,indicating it had high diagnostic value for moderate and severe septic shock.Conclusion The expression level of serum PAD2 was positively correlated with APACHE Ⅱ scores,and may have a good diagnostic value for moderate and severe septic shock.
