Fibronectin (FN) may be involved in time- and stage-dependent and inter-related controlled processes of inflammation, coagulation, and wound healing accompanying peripheral arterial disease (PAD). In the present study, FN and FN-containing extra-domain A (EDA-FN), macromolecular FN-fibrin complexes, and FN monomer were analysed in the plasma of 142 PAD patients, including 37 patients with restenosis, for 37 months after revascularisation. FN concentration increased significantly in the plasma of PAD patients within 7 to 12 months after revascularisation, whereas the high concentration of EDA-FN was maintained up to 24 months, significantly higher in the group 7 to 12 months after revascularisation with recurrence of stenosis and lower in the PAD groups 1 to 3 months and 4 to 6 months after revascularisation with comorbid diabetes and ulceration, respectively. The relative amounts of FN-fibrin complexes up to 1600 kDa and FN monomer were significantly higher, within intervals of 4 to 24 months and 4 to 6 months after revascularisation, respectively. Moreover, the relative amounts of 750 to 1600 kDa FN-fibrin complexes within 13 to 24 months after revascularisation were higher in comparison with those in the group without restenosis. In conclusion, high levels of EDA-FN and FN-fibrin complexes could have potential diagnostic value in the management of PAD patients after revascularisation, predicting restenosis risk.
纤维连接蛋白 (FN) 可能参与了伴随外周动脉疾病 (PAD) 的炎症、凝血和伤口愈合的时间和阶段依赖性以及相互关联的受控过程。在本研究中,分析了 142 名 PAD 患者(包括 37 名再狭窄患者)在血管重建后 37 个月的血浆中 FN 和含有外显子 A 的 FN(EDA-FN)、大分子 FN-纤维蛋白复合物和 FN 单体。血管重建后 7 至 12 个月内,PAD 患者血浆中 FN 浓度显著增加,而 EDA-FN 的高浓度一直持续到 24 个月,在再狭窄复发的血管重建后 7 至 12 个月的组中显著更高,在血管重建后 1 至 3 个月和 4 至 6 个月的伴有合并糖尿病和溃疡的 PAD 组中则较低。在血管重建后 4 至 24 个月和 4 至 6 个月的间隔内,相对较高分子量的 FN-纤维蛋白复合物(高达 1600 kDa)和 FN 单体的含量也显著升高。此外,血管重建后 13 至 24 个月内 750 至 1600 kDa FN-纤维蛋白复合物的相对含量与无再狭窄组相比更高。总之,EDA-FN 和 FN-纤维蛋白复合物的高水平可能在外周动脉疾病患者血管重建后的管理中具有潜在的诊断价值,可预测再狭窄风险。
