Objective: To evaluate the efficacy, tolerance and acceptability of UrgoStart Contact (Laboratoires Urgo), a new wound dressing impregnated with NOSF, as an MMP regulator in the management of neuropathic diabetic foot ulcers.
Method: A multicentre, pilot, prospective, non-controlled open-label clinical trial. Adult patients with type 1 or 2 diabetes mellitus, who had a grade 1A (Texas classification), uninfected, neuropathic foot ulcer, 1-15cm2 in size and of 1-20 months' duration (mean 6.7 ± 5.2 months) were included in the study. The primary endpoint was the relative reduction of the wound surface area (%) at the end of the study. Secondary endpoints included rate of complete healing, and tolerability and acceptability of the dressing. The wound dressing was changed regularly at the investigator's discretion, in accordance with the wound status and exudate level. Patients were followed up every 2 weeks for a 12-week period. At each visit, patients underwent clinical assessments, and ulcer surface area was measured by planimetry and photographs.
Results: Thirty-four diabetic patients with a neuropathic foot ulcer were included but only 33 cases were analysed, as data were completely lost for one patient. At baseline, mean surface area was 2.7±2.4cm2. At the 12-week follow-up, the median surface area reduction was 82.7% (mean reduction 62.7 ± 49.9%) and in 10 of the 33 analysed patients (30%) the wound was healed. Only two of the seven documented local adverse events were deemed to be dressing related. According to the nursing staff, acceptability was considered very satisfactory, particularly in term of conformability and ease of use.
Conclusion: This pilot study indicates that use of the new UrgoStart Contact dressing, combined with offloading and debridement,may help promote the healing process of the neuropathic diabetic foot ulcers, and was well tolerated and accepted.
