Application value of heparin binding protein in the early diagnosis of sepsis in children

Department of Pediatrics, the First Affiliated Hospital of Bengbu Medical College, Bengbu, Anhui 233004, China

摘要

摘要: 目的研究肝素结合蛋白(heparin-binding protein, HBP)对早期诊断儿童脓毒症及病情评估的临床价值。方法选取2019年1月—2020年2月于蚌埠医学院第一附属医院住院治疗并诊断为脓毒症的患儿61例，根据患儿病情严重程度分为脓毒症组(35例)、严重脓毒症组(16例)以及脓毒性休克组(10例)，同期因局部感染住院治疗的患儿(30例)设为局部感染组。比较各组患儿血清HBP、降钙素原(procalcitonin，PCT)、C反应蛋白(C-reactive protein，CRP)水平，对比分析各指标诊断脓毒症的诊断效能。结果 4组患儿HBP、PCT、CRP组间总体比较差异均具有统计学意义(F=162.024、78.944、10.982，均P < 0.05);HBP水平分别为(19.74±15.20)μg/L、(34.79±14.08)μg/L、(57.42±14.63)μg/L、(191.20±53.28)μg/L，PCT水平分别为(1.33±1.07)ng/mL、(3.38±2.63)ng/mL、(9.93±6.65)ng/mL、(18.13±1.45)ng/mL，随病情加重而升高，差异均具有统计学意义(均P < 0.05);脓毒性休克组CRP[(79.47±18.94)mg/L]与严重脓毒症组[(73.60±26.22)mg/L]比较差异无统计学意义(P>0.05)，其余各组CRP水平组间两两比较差异均具有统计学意义(均P < 0.05)。ROC曲线分析显示，3项指标联合检测诊断脓毒症时具有最大的曲线下面积(AUC=0.922)，敏感度为72.13%，特异度为96.67%。结论血清HBP在儿童脓毒症诊断方面具有良好价值，3项指标联合检测诊断效能优于单一检测。

Abstract: Objective To examine the clinical value of heparin-binding protein (HBP) in the early diagnosis and evaluation of childhood sepsis. Methods Total 61 children with sepsis who were hospitalized in the First Affiliated Hospital of Bengbu Medical College from January 2019 to February 2020 were selected and divided into sepsis group (35 cases), severe sepsis group (16 cases) and septic shock group (10 cases) according to the severity of the disease. Meanwhile, 30 children who were hospitalized due to local infection were set as local infection group. The levels of HBP, procalcitonin (PCT), and C-reactive protein (CRP) were compared per group, and the efficacy of each indicator in diagnosing sepsis was compared and analysed. Results The overall differences amongst the four groups were statistically significant (F=162.024, 78.944, 10.982, all P < 0.05). The levels of HBP were (19.74±15.2) μg/L, (34.79±14.08) μg/L, (57.42±14.63) μg/L, (191.20±53.28) μg/L; the levels of PCT were (1.33±1.07) ng/mL, (3.38±2.63) ng/mL, (9.93±6.65) ng/mL, (18.13±1.45) ng/mL, respectively, and increased with the aggravation of the disease (all P < 0.05). No statistically significant difference in CRP level existed between the septic shock group [(79.47±18.94) mg/L] and the severe sepsis group [(73.60±26.22) mg/L, P>0.05], and pausal differences between the other groups were statistically significant (all P < 0.05). ROC curve analysis showed that the maximum area under the curve (AUC) was 0.922, sensitivity was 72.13%, and specificity was 96.67% when the three indicators were combined to diagnose sepsis. Conclusion Serum HBP has good value in diagnosing childhood sepsis, and the combined detection of the three indices is better than single detection.
