Abstract Background Elevated level of D-dimer increases the risk of ischemic stroke, stroke severity and progression of stroke status, but the association between D-dimer and functional outcome is unclear. The aim of this study is to investigate whether Plasma D-dimer level is a determinant of short-term poor functional outcomes in patients with acute ischemic stroke (AIS). Methods This prospective study included 877 patients with AIS provided plasma D-dimer level after stroke onset. Patients were categorized per D-dimer level: Quartile 1(≤0.24 mg /L), Quartile 2 (0.25–0.56 mg /L), Quartile 3 (0.57–1.78 mg /L), and Quartile 4 (>1.78mg /L). Each patient’s medical record was reviewed, and demographic, clinical, laboratory and neuroimaging information was abstracted. Functional outcome at 90 days was assessed with the modified Rankin Scale (mRS). Results Of 877 patients were included (mean age, 64 years; male, 68.5%), poor outcome was present in 302 (34.4%) patients. After adjustment for potential confounding variables, higher D-dimer level on admission was associated with poor outcome (adjusted odds ratio [aOR] 2.257, 95% CI1.349-3.777 for Q4:Q1; P trend = 0.004). According to receiver operating characteristic (ROC) analysis, the best discriminating factor was a D-dimer level ≥0.315 mg/L for pour outcome [area under the ROC curve (AUC) 0.657; sensitivity 83.8%; specificity 41.4%]. Conclusion Elevated plasma D-dimer level on admission was significantly associated with increased poor outcome after admission for AIS, suggesting the potential role of D-dimer as a predictive marker for short-term poor outcomes in patients with AIS.

Abstract Background: Elevated level of plasma D-dimer increases the risk of ischemic stroke, stroke severity and progression of stroke status, but the association between plasma D-dimer level and functional outcome is unclear. The aim of this study is to investigate whether Plasma D-dimer level is a determinant of short-term poor functional outcome in patients with acute ischemic stroke (AIS). Methods: This prospective study included 877 Chinese patients with AIS admitted to Renmin Hospital of Wuhan University within 72 hours of symptom onset. Patients were categorized per plasma D-dimer level: Quartile 1(0.24 mg /L), Quartile 2 (0.25–0.56 mg /L), Quartile 3 (0.57–1.78 mg /L), and Quartile 4 (1.78mg /L). Each patient’s medical record was reviewed, and demographic, clinical, laboratory and neuroimaging information was abstracted. Functional outcome at 90 days was assessed with the modified Rankin Scale (mRS). Results: Of 877 patients were included (mean age, 64 years; male, 68.5%), poor outcome was present in 302 (34.4%) patients.

SummaryLiver disease is associated with markedly elevated plasma factor VIII (FVIII) levels, whereas the synthesis of many other coagulation factors and proteins is reduced. In order to define the mechanism of FVIII increase, we have determined the expression levels of FVIII, both at mRNA and protein level, in patients with liver disease who underwent partial liver resection. In addition, the expression of von Willebrand factor (VWF) and low density lipoprotein receptor-related protein (LRP), proteins known for their ability to modulate FVIII plasma levels, were examined. Tissue samples for RNA extraction were obtained from 4 patients with cirrhosis, 9 patients with liver failure without cirrhosis and 6 patients with liver metastasis of a colon or rectum carcinoma (control group). In patients with liver cirrhosis hepatic FVIII and LRP mRNA levels were significantly lower than controls (p ≤ 0.010), while VWF mRNA was significantly higher (p ≤ 0.050). Immunohistochemical analysis revealed that cellular VWF protein distribution was also increased in cirrhotic livers compared to liver tissue from patients with non-cirrhotic liver disease. In cirrhotic tissue enlarged portal veins appeared to overgrow FVIII producing sinusoidal endothelial cells. Similarly, the number of LRP-producing cells appeared to be lower in cirrhotic tissue than in controls. The plasma concentration of both FVIII and VWF was significantly higher in patients with cirrhosis than control subjects (p = 0.038 and 0.010 respectively). These results demonstrate that elevated plasma FVIII levels in liver cirrhosis are associated with increased hepatic biosynthesis of VWF and decreased expression of LRP, rather than increased FVIII synthesis.
