Abstract:
Objective:To observe the changes of serum histone H4 level and its predictive value in patients with septic cardiomyopathy.Methods:A prospective study was conducted. A total of 147 patients with sepsis and septic shock were collected in emergency department. The general data were recorded. Transthoracic echocardiography and plasma histone H4 were conducted within 24 hours and 7 days after admission.The scores of sequential organ failure assessment(SOFA), acute physiology and chronic health evaluationⅡ(APACHEⅡ), and nutritional risk screening 2002 (NRS2002) were evaluated within 24 hours. According to whether septic cardiomyopathy occurred, the patients were divided into two groups, and dynamic changes of histone H4 on the first and seventh day of the two groups were observed. The factors influencing the occurrence of septic cardiomyopathy were analyzed by multivariate logistic regression. The prediction ability of serum histone H4 on septic cardiomyopathy was evaluated by receiver operating curve (ROC).Results:The incidence of septic cardiomyopathy was 28.6% (42 / 147). The level of histone H4 in septic cardiomyopathy group was higher than that in non septic cardiomyopathy group ( Z = 4.449, P < 0.001), and dynamic detection showed that the level of histone H4 on the seventh day was lower than that on admission ( Z=3.057, P=0.002). Multivariate logistic regression showed that the high serum histone H4 level [Odd Ratio( OR)=1.337, 95% confidence interval (95% CI) was 1.173-1.522, P < 0.001], SOFA ( OR= 1.474, 95% CI 1.227-1.769, P < 0.001), older age ( OR = 1.074, 95% CI 1.019-1.132, P = 0.008) were independent risk factors for septic cardiomyopathy. The area of ROC curve for serum histone H4 to predict septic cardiomyopathy was 0.729 ( P < 0.001), the predictive cut-off value was 10.81 ng/ml, which yielded a sensitivity 0.524 and a specificity of 0.914. Conclusions:The level of histone H4 showed dynamic change in septic cardiomyopathy, and high serum histone H4 level has a good predictive value for the occurrence of septic cardiomyopathy.
