Fasudil inhibits tissue factor and plasminogen activator Inhibitor-1 secretion by peripheral blood mononuclear cells in CAPD patients

Disturbances in hemostasis are common complications of kidney diseases and correlate well with cardiovascular mortality. Little is known about the effects of fasudil on tissue factor (TF) and plasminogen activator inhibitor-1 (PAI-1) expression in peripheral blood mononuclear cells (PBMCs) in CAPD patients. PBMCs were isolated from 13 individuals with CAPD and 13 healthy subjects. After 4 h of incubation with or without LPS (10 ng/mL), TF and PAI-1 mRNA of PBMCs were detected by RT-PCR. The levels of TF and PAI-1 in culture supernatants of PBMCs were determined by ELISA. Compared with healthy controls, CAPD patients had increased TF, PAI-1 protein and mRNA expression by PBMCs at baseline and after stimulated by LPS (10 ng/mL) [p < 0.001]. The fasudil treatment resulted in a significant effect in decreasing TF and PAI-1 [p < 0.05] synthesis in PBMCs. TF and PAI-1 mRNA expression and activities in PBMCs were increased in CAPD patients. Fasudil reduced LPS-mediated TF and PAI-1 expression and activity in PBMCs. These effects may partially be relevant to the clinical benefits of fasudil in the treatment of CAPD patients.
