title: Effectiveness and safety of a novel gel dressing in the management of neuropathic leg ulcers in diabetic patients: a prospective double-blind randomized trial.
abstract: Neuropathic leg ulcers (NLUs) affect more than 10% of diabetic patients with peripheral neuropathy and represent the most common cause of ulceration of the leg in these patients. Though their pathogenesis is well known, related to the chronic neuropathic edema, the management of NLUs, mainly based on elastocompression, is still controversial, with lower healing rates than nondiabetic venous leg ulcers. The authors tested if a novel gel formulation, containing amino acids and hyaluronic acid (Vulnamin)gel; Errekappa, Milan, Italy), will improve the outcomes of NLUs when used together with elastocompression. Thirty patients affected by NLU were randomized into 2 groups, both treated with 4-layer elastocompressive bandaging: patients in group A were topically treated with the application of Vulnamin) gel, whereas patients in group B received only the inert gel vehicle. The healing rate at 3 months was evaluated as the primary endpoint, whereas the secondary endpoints were healing time, reduction in ulcer area and ulceration score in 4 weeks, number of infective complications, and overall satisfaction of patients. Healing rate was significantly (P < .05) higher in patients in group A when compared with those in group B; healing time, patients' satisfaction, and reduction in ulcer area and ulceration score in 4 weeks were also higher in patients in group A. However, no significant differences were found in the prevalence of infections and other adverse events. The use of Vulnamin) gel with elastocompression is safe and effective in the management of NLUs of diabetic patients.
