Efficacy of the Combination of Isosorbide Dinitrate Spray and Chitosan in Diabetic Foot Ulcers

Detailed Summary

The prevalence of diabetic foot ulceration in the diabetic population is 4-10%; the condition is more frequent in elder patients. It is estimated that about 5% of all patients with diabetes present a history of foot ulceration, while the lifetime risk of diabetic patients developing this complication is 15%. The majority (60-80%) of foot ulcers will heal, while 10-15% of them will remain active, and 5-24% of them will finally lead to limb amputation within a period of 6-18 months after the first evaluation , 2 out of 3 patients with a limb amputation could also be involved in a new amputation in the next year; higher or in the other leg , Eighty-five percent of lower-limb amputations in patients with diabetes are preceded by foot ulceration. The management of chronic diabetic foot ulcers (DFU) suggests multi-disciplinary approaches including control of diabetes, orthotic shoe wear, off-loading device, wound care and surgery in selected cases. However, treatment of DFU remains challenging because of unsatisfactory results from surgical and non-surgical treatments. Many adjunctive therapies are designed to improve the care of DFU including negative pressure wound therapy , ultrasound, recombinant human platelet-derived growth factor-BB (rPDGF-BB) Hyperbaric oxygen and acellular matrix product among others.
