ABSTRACT
Objective@#To demonstrate the relevance of heart-type fatty acid binding protein(H-FABP) and brain glycogen phosphorylase isoenzyme type(GPBB) with myocardial injury in sepsis.To explore the effect of H-FABP and GPBB on the severity of disease and clinical prognosis.@*Methods@#A total of 40 cases of children with sepsis were selected in this study from January 1, 2017 to October 31, 2017.According to the illness severity, they were divided into sepsis group(n=15), severe sepsis group(n=13) and septic shock group(n=12), 19 cases of children with non-infectious diseases were selected as the control group for the same period.The levels of serum WBC, C-reactive protein, procalcitonin, cTnI, CK, CK-MB, CK-MB isoenzyme quality and NT-proBNP were collected within 24 hours of admission.The APECHEⅡ scores were calculated for each child.The peripheral blood of the patients within 24 hours after admission was used to determine the levels of serum H-FABP and GPBB by ELISA method.The differences of clinical indicators among the groups were analyzed.According to the survival of patients with sepsis, they were divided into 37 cases in the improved group and 3 cases in the death group.All patients with sepsis were divided into left ventricular ejection fraction(LVEF) normal group(n=26) and LVEF decreased group(n=14). According to whether the serum cTnI was elevated, all children with sepsis were divided into cTnI normal group (n=29) and cTnI increased group (n=11). The differences of H-FABP and GPBB levels were compared.According to the presence or absence of LVEF decline, the area under the ROC curve was used to evaluate the predictive power of each index for myocardial injury in sepsis.Based on the decrease of LVEF, the area under the ROC curve was used to evaluate the prediction of each index for myocardial injury in sepsis.@*Results@#There were significant differences in H-FABP and GPBB levels among the control group, sepsis group, severe sepsis group and the septic shock group (H=42.241, P<0.05; H=32.486, P<0.05). Although there was no significant difference between the improved group and the death group(P>0.05), there was an elevated trend of H-FABP and GPBB in the death group.The levels of H-FABP (t=-3.770, P=0.001) and GPBB (Z=-2.113, P=0.033) were statistically significant in the LVEF normal group and the LVEF decreased group (LVEF≤60%). There were no significant differences in the levels of H-FABP and GPBB between the cTnI normal group and the cTnI increased group (P>0.05), but the cTnI increased group had an increasing trend.The area under the ROC curve in the diagnosis of myocardial injury in sepsis were H-FABP 0.821, NT-ProBNP 0.738, GPBB 0.661, CK 0.560, cTnI 0.512, in which the sensitivity(0.833) and specificity(0.786)of H-FABP were both higher.@*Conclusion@#The serum H-FABP and the GPBB levels can be used to monitor for myocardial damage, and it has a correlation with the severity of the disease and the prognosis.H-FABP has a significant advantage over traditional myocardial markers in sensitivity and specificity to determine the myocardial injury of sepsis.
ABSTRACT
The incidence of sepsis is on the rise, and the mortality is also high. Myocardial injury caused by sepsis is one of the important causes of death. However,there is no clear and unified diagnostic criteria to sepsis complicated with myocardial injury. The clinical diagnostic criteria of myocardial injury is mainly based on cardiac ultrasound,myocardial markers and so on. But the measurement of ejection fraction is needed to consider the impact of preload and afterload of left ventricula,also the subjective level of opera-tors. So cardiac markers play an important role in the detection of myocardial injury in sepsis and can reflect the severity of myocardial injury and sepsis,especially in the early diagnosis and prognosis. Heart-type fatty acid binding protein and brain glycogen phosphorylase isoenzyme type exhibit higher sensitivity, specificity and stability compared to other traditional cardiac markers in the clinical diagnosis of myocardial injury, which are worth to be studied and applied in the clinical diagnosis of myocardial injury.
