title: Plasma prothrombotic markers after a short- and middle term treatment with iloprost in arteriopathic patients with critical limb ischemia.
abstract: The authors carried out an investigation on the "short" and "middle-term" effect of the prostanoid derivate iloprost on some molecular haemostatic markers in a group of peripheral vasculopathic patients with critical limb ischemia. The series consists of 10 patients (6 males, 4 females, age 52 +/- 5) suffering from peripheral obstructive vasculopathy at the III-IV stage by Fontaine. After overnight fasting, each patient was given an intravenous infusion of iloprost lasting six hours at the rate of 2 ng/kg/min and reaching approximately the global dosage of 50 gamma; before and after the infusion a venous blood sample was withdrawn; the experiment was repeated under the same conditions after a four week treatment with the drug administered daily at the same dosage. For each sample the plasma levels of betathromboglobulin (BTG) fibrinopeptide A (FPA), tissue plasminogen activator (tPA), plasminogen activator inhibitor (PAI-I) and D-dimer (D-D) (ELISA, methods, kits Boehringer) were measured. The basal values of BTG, FPA, tPA, PAI-I and D-D were significantly increased compared to those of a control group; after the iloprost infusion (acute effect) significant changes of the BTG, FPA, tPA and PAI-I were not found; D-D only showed a marked reduction (p < 0.05); after the four week treatment with infusion the basal values of BTG, FPA, tPA and PAI-I resulted almost unchanged; D-D only showed a marked reduction (p < 0.05) both as regards the basal value and those after the infusion.(ABSTRACT TRUNCATED AT 250 WORDS)
