          Aim: Damage to the endothelium is an important component of atherosclerosis. It has been suggested to be quantified by measuring plasma markers, such as von Willebrand factor and thrombomodulin and soluble adhesion molecules. We hypothesized there may exist a correlation between the plasma levels of von Willebrand factor and thrombomodulin as markers of endothelial cell dysfunction and the serum concentrations of soluble adhesion molecules and monocyte chemoattractant protein-1 (MCP-1) in patients with renal insufficiency, and in patients on peritoneal dialysis or hemodialysis since these three groups of kidney patients are highly prone to develop cardiovascular diseases. Results: The concentrations of von Willebrand factor and thrombomodulin in plasma were significantly higher in patients with kidney diseases as compared to healthy subjects (p = 0.017 and p < 0.001, respectively). The patients also had significantly higher concentrations of soluble vascular cell adhesion molecule-1 (sVCAM-1) and MCP-1 compared to healthy controls (p < 0.001 for both comparisons). There were strong correlations between the concentration of soluble intercellular adhesion molecule-1 (sICAM-1) and von Willebrand factor in patients with kidney failure (r = 0.63, p < 0.001) and between the concentration of thrombomodulin and sVCAM-1 (r = 0.61, p < 0.001). Furthermore, a negative correlation was observed between the concentration of thrombomodulin and the cell surface expression of CD11b on monocytes and granulocytes in the peripheral circulation (p < 0.01 in both cases). Conclusion: The strong correlation between markers of endothelial dysfunction and soluble adhesion molecules in patients with renal insufficiency and on dialysis strengthen the view that an ongoing stress on endothelial cells is present in this group of patients. This may play a pathophysiological role in the development of cardiovascular disease.

          Relationship between endothelial cell markers and arterial stenosis in peripheral and carotid artery disease.

          Damage to the endothelium is an important component of atherosclerosis and can be quantified by measuring plasma markers, such as von Willebrand factor, thrombomodulin, intercellular adhesion molecule-1, and E-selectin. We hypothesized that increased levels of these markers would be related to objectively defined disease severity among patients with peripheral atherosclerosis or carotid atherosclerosis. To test this, we measured the markers by using ELISA in the plasma of 45 patients with intermittent claudication alone and in 53 patients presenting with transient ischemic attack. Disease severity in the former was by ankle-brachial pressure index and in the latter by ultrasound defined % stenosis. Any symptomatic dual disease or history or present coronary atherosclerosis warranted exclusion. Data were correlated according to Spearman's method. The only significant correlation was between von Willebrand factor and ankle-brachial pressure index (r = -0.39, p = 0.008). Our data suggest that von Willebrand factor is the most sensitive marker of peripheral atherosclerosis and that none of the plasma markers seems to be a useful marker of the degree of carotid artery stenosis.

            Monocyte-Related Determinants of Inflammation in Patients on Peritoneal Dialysis

            Aims: We studied markers of monocyte activation, i.e., the cell surface expression of CD11b and CD62L, and the serum concentrations of monocyte chemotactic protein 1 (MCP-1; a monocyte-specific chemoattractant) and soluble vascular cell adhesion molecule 1 (sVCAM-1; an adhesion molecule involved in monocyte recruitment) in 20 patients on peritoneal dialysis (PD), in 25 patients with chronic renal insufficiency, and in 27 healthy subjects. Results: Monocytes obtained from the peripheral blood of PD patients had a significantly higher expression of CD62L (p = 0.02) as compared with monocytes from healthy subjects and a lower CD11b/CD18 expression as compared with monocytes collected from healthy subjects (p high /CD11b low phenotype, indicating that they have not undergone complete differentiation. Patients also have an increase in the systemic chemotactic activity for monocytes in combination with increased levels of sVCAM-1 and C-reactive protein. These inflammatory aberrations may play a pathophysiological role in the response to inflammatory and infectious diseases in patients on PD.
