Effects of defibrotide on peripheral obliterative vascular diseases
Insights
Defibrotide therapy improved blood flow and reduced pain in patients with vascular disorders like atherosclerotic obliterative vascular disorder and Buerger
Area of Science:
- Vascular Medicine
- Pharmacology
Background:
- Atherosclerotic obliterative vascular disorder and Buerger's disease cause significant pain and reduced mobility.
- Effective treatments for these conditions are crucial for improving patient quality of life.
Purpose of the Study:
- To evaluate the efficacy of defibrotide in patients with atherosclerotic obliterative vascular disorder and Buerger's disease.
- To assess the impact of defibrotide on pain, vascular function, and blood flow.
Main Methods:
- A study involving 29 patients with atherosclerotic obliterative vascular disorder and 9 with Buerger's disease.
- Treatment with 600 mg defibrotide daily for 10 days, followed by thrice-weekly for 3 months.
- Evaluation using hemostatic parameters, venostasis (cuff) test, treadmill testing, and radionuclide arteriography.
Main Results:
- Patients experienced increased pain-free intervals in daily life and during treadmill tests.
- Significant improvements were observed in the cuff test results.
- Radionuclide arteriography indicated enhanced blood perfusion.
Conclusions:
- Defibrotide therapy shows promise in improving clinical outcomes for patients with atherosclerotic obliterative vascular disorder and Buerger's disease.
- The drug positively impacts pain reduction, vascular function, and blood flow in these patient populations.
Abstract:
Twenty-nine patients with atherosclerotic obliterative vascular disorder and 9 cases of Buerger's disease were treated with 600 mg defibrotide daily for 10 days and then three times weekly for 3 months. The response to therapy was evaluated from hemostatic parameters, venostasis test (cuff test), treadmill testing, and radionuclide arteriography. We observed increased pain-free intervals in daily life and during treadmill testing. There was also a significantly higher response in the cuff test and improved perfusion as seen by radionuclide arteriography.
