[摘要] 目的 探討血清肝素結(jié)合蛋白(HBP)在膿毒血癥患者急性腎衰竭過程中的表達(dá)與意義,了解其臨床價(jià)值。方法 選取2014年9月~2017年9月于首都醫(yī)科大學(xué)附屬北京潞河醫(yī)院急診就診的124例膿毒血癥患者,根據(jù)是否發(fā)生急性腎衰竭分為膿毒血癥急性腎衰竭組42例(A組),膿毒血癥無急性腎衰竭組82例(B組),另選取非膿毒血癥急性腎衰竭患者60例(C組),以及60名健康志愿者(D組)作為健康對照組。每組分別在入院24 h內(nèi)及在相應(yīng)治療后采集靜脈血,測定血清中HBP和血肌酐濃度水平。 結(jié)果 治療前,膿毒血癥患者與健康對照組比較,A組和B組HBP水平明顯高于C組和D組(P < 0.05),而發(fā)生急性腎衰竭的A組血清中HBP濃度較B組明顯升高(P < 0.05)。治療后,只有A組HBP水平有明顯下降(P < 0.05)。 結(jié)論 HBP可作為評估膿毒血癥患者急性腎衰竭的發(fā)生指標(biāo),也可作為評價(jià)其治療效果的一種方法。

[Abstract] Objective To investigate the purpose of this study was to investigate the expression and significance of serum heparin binding protein (HBP) in the process of acute renal failure in patients with sepsis and to understand its clinical value. Methods From September 2014 to September 2015, 124 patients with sepsis admitted to the emergency Department of Beijing Luhe Hospital Affiliated to Capital Medical University were selected. According to the occurrence of acute renal failure, 42 patients in the acute renal failure group with sepsis (group A), 82 patients in the group without acute renal failure group with sepsis (group B), 60 patients with acute renal failure without sepsis (group C), and 60 healthy volunteers (group D) were selected as the healthy control group. Venous blood was collected in each group within 24 h after admission and after corresponding treatment, and serum HBP and serum creatinine concentrations were measured. Results Before treatment, compared with the healthy control group, the HBP level of group A and group B was significantly higher than that of group C and group D (P < 0.05), while the serum HBP level of group A with acute renal failure was significantly higher than that of group B (P < 0.05). After treatment, only group A showed A significant decrease in HBP level (P < 0.05). Conclusion HBP can be used as a method to evaluate the occurrence of acute renal failure in patients with sepsis and to evaluate its therapeutic effect.

在急診就診的各類患者中,許多患者體內(nèi)存在著感染病灶,無論是外傷后的軟組織感染、糖尿病足或者是以急腹癥為表現(xiàn)的腹腔臟器感染。隨著人口老齡化和糖尿病患者的增多,急診的重癥感染患者逐步增多,某些患者初次就診時(shí)即可診斷為膿毒血癥,而膿毒血癥患者最為常見的并發(fā)癥是急性腎損傷(AKI)。合并AKI的膿毒血癥患者其預(yù)后較差,如治療不及時(shí),死亡率也較高。因此,有必要找到一種準(zhǔn)確、靈敏的指標(biāo),用來診斷和評估膿毒血癥患者急性腎衰竭的發(fā)生和發(fā)展。目前,評估急性腎衰竭的主要指標(biāo)是血清肌酐濃度,但其缺乏靈敏性,無法預(yù)測急性腎衰竭是否加重,以及是否需要透析治療[1]。
研究[2-3]發(fā)現(xiàn),肝素是一種帶負(fù)電荷的黏多糖,與血清肝素結(jié)合蛋白(HBP)結(jié)合,發(fā)揮多種功能。肝素的諸多衍生產(chǎn)物或許有助于重癥感染的治療[4],并且在小鼠體內(nèi)可以減緩急性腎衰竭的發(fā)展[5]。肝素除了抗凝作用外,還具備其他多種生理學(xué)作用,其中就包括抗炎作用,這或許可以作為膿毒血癥治療的新的一條路徑。本研究探討了膿毒血癥所致急性腎衰竭患者HBP的表達(dá)水平,了解HBP在膿毒血癥急性腎衰竭診斷及治療評估中的臨床意義。
