We studied some endothelial cell activity plasma markers, nitric oxide (NO), thrombomodulin (TM), selectins (sP-, sE-,sL-selectin:platelet-P, endothelium-E, leukocyte-L), and tissue factor pathway inhibitor (TFPI) in 14 patients with chronic obstructive pulmonary disease (COPD), matched with 20 normal controls, to evaluate their endothelial cell dysfunction. Both NO (patients: 23.42 ± 1.67 μg/mL; controls: 40.0 ± 3.38 μg/mL) and TM levels (patients: 5.46 ± 1.32 ng/mL; controls : 12.9 ± 0.51 ng/mL) were significantly decreased in COPD (p < 0.001). sP-selectin levels (patients: 79.42 ± 18.20 ng/mL, controls: 37.5 ± 2.84 mg/mL) were significantly higher (p < 0.02), whereas sL-selectin levels (patients: 584.9 ± 78.98 ng/mL, controls: 1054.02 ± 61.28 ng/mL) were significantly decreased in patients with COPD (p < 0.001). In contrast, no differences were seen in sE-selectin. Patients with COPD showed a significantly higher (p < 0.001) TFPI antigen plasma level (mean 112.28 ± 6.45 ng/mL; controls 77.68 ± 0.28 ng/mL) than controls. Our data support the concept of some form of endothelial cell dysfunction, and coagulation abnormalities are present in patients with COPD. However, because the endothelium seems to produce a defense mechanism, the potential usefulness of an antithrombotic therapy in these patients needs further investigation.
我们研究了一些内皮细胞活性血浆标志物,包括
一氧化氮(NO)、凝血调节因子(TM)、选择素(sP-、sE-、sL-选择素:血小板-P、内皮-E、白细胞-L)和组织因子通路
抑制剂(
TFPI)在14名慢性阻塞性肺疾病(
COPD)患者中的表现,与20名正常对照组进行匹配,以评估他们的内皮细胞功能障碍。
COPD患者的NO(23.42±1.67μg/mL;对照组:40.0±3.38μg/mL)和TM
水平(患者:5.46±1.32 ng/mL;对照组:12.9±0.51 ng/mL)均显著降低(p<0.001)。sP-选择素
水平(患者:79.42±18.20 ng/mL,对照组:37.5±2.84 mg/mL)显著升高(p<0.02),而sL-选择素
水平(患者:584.9±78.98 ng/mL,对照组:1054.02±61.28 ng/mL)在
COPD患者中显著降低(p<0.001)。相反,sE-选择素没有差异。
COPD患者显示出显著较高的
TFPI抗原血浆
水平(平均112.28±6.45 ng/mL;对照组77.68±0.28 ng/mL)(p<0.001)。我们的数据支持内皮细胞功能障碍和凝血异常在
COPD患者中存在的概念。然而,由于内皮细胞似乎产生了一种防御机制,抗血栓治疗在这些患者中的潜在用途需要进一步研究。
