BMC Gastroenterology:肝素结合蛋白显着升高急性胰腺炎患者疾病严重程度相关

2021-09-26 MedSci原创 MedSci原创

大多数急性胰腺炎 (AP) 患者表现为轻度、自限性疾病,几乎不需要住院治疗。然而,20-25% 的患者会出现严重且可能危及生命的并发症。

      大多数急性胰腺炎 (AP) 患者表现为轻度、自限性疾病,几乎不需要住院治疗。然而,20-25% 的患者会出现严重且可能危及生命的并发症,伴有进行性全身炎症反应综合征 (SIRS) 和多器官衰竭,导致很高的死亡率,因此,早期识别潜在严重疾病的患者至关重要。此外,即时支持治疗已被证明可以降低 SIRS 和器官衰竭的发生率,从而改善患者的预后。液体复苏在急性胰腺炎中的作用最近越来越受到关注。使用早期补液来对抗低血压和血液浓缩被认为可以保护胰腺中的微循环,防止进一步的损伤和坏死。然而,关于这些患者的最佳输液速度和液体量存在争议。因此,分析每个患者的液体需求量的方法将具有重要的临床价值。

 

      肝素结合蛋白 (HBP),也称为 CAP37或azurocidin,是一种储存在中性粒细胞中的嗜天青颗粒和囊泡中的糖蛋白,在全身炎症反应的早期中性粒细胞激活时释放。此外,HBP 已被证明会增加内皮细胞通透性,导致败血症和其他炎症性疾病中的。血管功能障碍和血浆液体渗漏。几项研究报告称,脓毒症和感染性休克患者的 HBP 水平升高。由于 HBP 水平先于其他已知生物标志物(例如C 反应蛋白 (CRP)、降钙素原、白细胞计数 (WBC) 和乳酸)升高,因此它可能是严重脓毒症伴器官功能障碍的早期预测指标。

 

 

       因此,本研究的目的是探究AP患者中HBP的浓度是否升高以及HBP是否可以用作严重疾病的早期预测生物标志物。

 

 

      研究人员将2010 年至 2013 年间入住马尔默斯科讷大学医院且符合 AP 标准的患者前瞻性地纳入本研究。主要观察结果是确诊的 AP 患者入院时测量的 HBP 水平。HBP 浓度、疾病严重程度和体液平衡之间的相关性被认为是次要终点。使用 Pearson 相关分析 HBP 水平与体液平衡之间的相关性,使用受试者工作特征 (ROC) 曲线评估 HBP 预测中重度/重度 AP 的能力。

      

      本研究中的总体 HBP 中位数水平为 529 (307–898) ng/ml。基于 AP 严重程度的 HBP 水平没有显着的组间差异。轻度、中度和重度胰腺炎患者的体液平衡存在显着差异,但研究人员发现 HBP 浓度与体液平衡之间没有相关性。

 

      本项研究证实AP 患者的 HBP 水平显着升高,并且这些水平远远超过先前在其他疾病情况下报道的水平。在这项研究中,研究人员没有观察到 HBP 水平与疾病严重程度或静脉输液需求之间的任何显着相关性。因此,需要进一步研究 HBP 以进一步探讨 HBP 在 AP 发病机制中的作用及其可能的临床意义。
