Pressure ulcer is a common occurrence in spinal cord injured (SCI) patients and can lead to serious complications. With proper management, some patients exhibit satisfactory healing whereas others show slow or nonhealing ulcers. Fibronectin has been shown to accumulate in wound, opsonize macroaggregate debris for phagocytosis, promote revascularization, and facilitate fibroblast migration and proliferation. We explored the relationship of plasma fibronectin with healing potential in 21 SCI men with pressure ulcer. They received standard wound care and were observed for eight weeks. Ten otherwise healthy SCI men without pressure ulcer (SCI-controls) and 32 able-bodied normal individuals (normal controls) were also studied. Plasma fibronectin and related proteins, ie, fibrinogen, plasminogen, alpha 2-antiplasmin and Factor XIII, were measured. Ten of 21 SCI patients with pressure ulcer showed rapid healing within four weeks and had significantly higher fibronectin levels as compared with the 11 patients with poor healing ulcers, SCI controls, and normal controls. Factor XIII and alpha 2-antiplasmin were mildly reduced and fibrinogen values were significantly increased in all SCI groups. Plasminogen concentrations were comparable in all groups studied. It thus appears that plasma fibronectin rises in patients with fast healing ulcers but fails to do so in those with poor healing ulcers and as such may be predictive of the course of pressure ulcers. |
