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. Sulodexide (10 mg/kg b.w.) was used acutely as supplement to the dialysis fluid or chronically, during 7 days preceding the study by intramuscular (i.m.) injection.
Results:
In rats given i.m. sulodexide the dialysate cell count was lower by 45% (p < 0.001) versus untreated rats with peritonitis. Dialysate elastase activity in i.m. sulodexide-treated rats was lower by 22% (p < 0.05) compared to peritonitis. In rats treated with i.m. sulodexide the increase of plasma tumor necrosis factor-alpha was reduced by 53% (p < 0.002). Pretreatment with i.m. sulodexide reduced transperitoneal loss of total protein and albumin during peritonitis by 26% (p < 0.002) and by 16% (p < 0.05), respectively.
Conclusion:
Sulodexide given systemically reduces the intraperitoneal and vascular inflammatory response during acute peritonitis in rats.
