Sulodexide reduces glucose induced senescence in human retinal endothelial cells.

Chronic exposure of retinal endothelium cells to hyperglycemia is the leading cause of diabetic retinopathy. We evaluated the effect of high glucose concentration on senescence in human retinal endothelial cells (HREC) and modulation of that effect by Sulodexide. Experiments were performed on HREC undergoing in vitro replicative senescence in standard medium or medium supplemented with glucose 20 mmol/L (GLU) or mannitol 20 mnol/L (MAN).

Sulodexide Slows Down the Senescence of Aortic Endothelial Cells Exposed to Serum from Patients with Peripheral Artery Diseases.

Background/aims: Aging of the arterial endothelial cells results in the appearance of their inflammatory phenotype, which may predispose patients to the acceleration of arteriosclerosis. We studied the effect of serum from patients with peripheral artery disease (PAD) on the senescence of human aortic endothelial cells (HAEC) and how that process is modulated by sulodexide.

Methods: HAEC replicative aging in vitro was studied in the presence of 10% PAD-serum (PAD Group) or10%PAD serum and Sulodexide 0.

Sulodexide Reduces the Proinflammatory Effect of Serum from Patients with Peripheral Artery Disease in Human Arterial Endothelial Cells.

Background/aims: Dysfunction of the arterial endothelial cells promotes the progression of atherosclerosis. We studied how exposure of human arterial endothelial cells to atherosclerotic serum from patients with peripheral artery disease changes the secretory activity of these cells, and whether that reaction is modified by sulodexide.

Methods: Endothelial cells in in vitro culture were exposed to standard culture medium ± 100pg/mL Interleukin-1(IL-1) or to medium supplemented with 20% atherosclerotic serum.

Sulodexide reduces the inflammatory reaction and senescence of endothelial cells in conditions involving chronic venous disease.

Background: According to previous studies, sulodexide suppresses intravascular inflammation when used in patients with chronic venous disease (CVD). In the current study, we tested the effect of prolonged in vitro exposure of human venous endothelial cells to the serum from patients with CVD, examining the function of these cells and how it is modified when these cells are simultaneously exposed to sulodexide.

Methods: Human umbilical venous cells (HUVEC) were cultured in standard medium (control), in medium supplemented with 5% serum pooled from CVD patients (CVD-serum) or in medium from CVD patients who were treated with sulodexide (CVD-serum-SUL).

Sulodexide modifies intravascular homeostasis what affects function of the endothelium.

Purpose: Sulodexide is a mixture of heparin and dermatan sulphate which has an antithrombotic action. It was shown that it has also direct effect on the endothelial cells. We tested the effect of sulodexide on the intravascular homeostasis in patients with peripheral vascular disease.

Sulodexide reduces senescence-related changes in human endothelial cells.

Background: Senescent endothelial cells acquire functional properties that make the vascular wall more prone to atherosclerotic changes. We tested whether senescence of the endothelial cells maintained in in vitro culture can be moderated by their simultaneous exposure to sulodexide.

Material/methods: Replicative aging of the endothelial cells was studied during their 15 passages performed every 4 days in cells cultured in standard medium or in medium supplemented with sulodexide 0.

Sulodexide suppresses inflammation in human endothelial cells and prevents glucose cytotoxicity.

Sulodexide is a mixture of heparin and dermatan sulfate with antithrombotic and profibrynolytic activity. Individual reports suggest the anti-inflammatory action of sulodexin. The goal of this study was to evaluate the effect of sulodexide on the release of the inflammatory mediators from endothelium in normal conditions and in cells chronically exposed to glucose.

Anti-inflammatory effect of sulodexide during acute peritonitis in rats.

Background/aims: Peritonitis is one of the complications of peritoneal dialysis. We demonstrate the systemic and intraperitoneal anti-inflammatory action of sulodexide given systemically.

Methods: Dialysis was performed in male Wistar rats with acute peritonitis induced by addition of endotoxin to the fluid.
