Optimization of Treatment in Patients With Severe Peripheral Ischemia (Fontaine Stage IIb)

Phase 4
Completed
Conditions
Peripheral Arterial Disease
Interventions
Drug: Standard Treatment (aspirin.....),
Registration Number
NCT01718288
Lead Sponsor
Fadoi Foundation, Italy
Brief Summary

Evaluate the possibility of optimization of therapy with prostanoids (iloprost), in patients with Fontaine's stage IIb severe chronic ischemia, both in patients eligible for surgery both in patients for which it is only possible medical therapy

Detailed Description

The management of patients with peripheral arterial disease (PAD) stage IIb and pain-free walking distance (PFWD) less than 100 meters is a major clinical problem, in view of the significant cooling of the quality of life and evolution often severe that characterizes the clinical course of these patients. Revascularization Surgery is the treatment of choice, but about half of patients with severe PAD IIb is not eligible for surgery or endovascular treatment. The usefulness of use of vasodilators or hemorheological is controversial, and medical treatment of these patients is therefore heterogeneous understanding the various pharmacologic options (for the correction of risk factors, prevention of cardiovascular events, improvement of claudication), and rehabilitative programs. Iloprost, a synthetic analogue of prostacyclin, is effective in the treatment of patients with chronic critical ischemia, and its pharmacological profile (effective vasodilator, anti-platelet, and leukocyte activation) is particularly suitable to modulate multiple components pathogenesis of peripheral arterial disease. Specifically, in the treatment of patients with PAD IIb severe, the current state is available only a retrospective study that compared the use of iloprost with that of vasodilators. Aim of the study FADOI-2bPILOT is to evaluate prospectively and for an observation period of 13 months, if you can get a benefit on the pain-free walking distance and on clinical outcome from "anticipated" and additional use of iloprost, in patients with severe IIb stage PAD treated according to current "best medical practice".

Primary Outcome Measures
NameTimeMethod
Measure of PFWD(pain-free walking distance)in patients with 2b stage PAD13 months

Aim of this multicenter, randomized, controlled study was prospectively evaluate the effects of iloprost, added to standard therapy, in patients with 2b stage PAD and PFWD (pain-free walking distance) less than 100 metres, eligible and non-eligible for surgical revascularization. A treadmill test 3-6-9-12 months (before iloprost cycle for patients group 1B and 2B). A final evaluation 13 months (for one month to the conclusion of the 12 months treatment of iloprost for patients group 1B and 2B, and after 13 months from enrolling for patients in the study group 1A and 2A)

Secondary Outcome Measures
NameTimeMethod
Assessing changes in endurance13 months

A clinical evaluation 3-6-9-12 months (before iloprost cycle for patients group 1B and 2B). A final evaluation 13 months (for one month to the conclusion of the 12 months treatment of iloprost for patients group 1B and 2B, and after 13 months from enrolling for patients in the study group 1A and 2A)

The possible occurrence of major complications13 months

The study reported the number of events during all the study (13 months). The major complication were: Ischemic cardiopathy, critical limb ischemia, cerebrovascular event, critical limb ischemia

Quality of life13 months

For the Quality of life, the study used a specific questionnaire administrated to all patients enrolled in the study (13 months of observation): IQOLA (International Quality of Life Assessment),SF-36 Italian Version 1.6
