Abstract (original English)

Diabetic foot ulcers (DFUs) are one of the most serious and devastating complication of diabetes mellitus, affecting about 15% of diabetic patients. This review describes the innovative treatment options currently available in the treatment of non-healing DFUs. The use of Platelet-Rich-Plasma (PRP) is a safe and valid approach in the treatment of DFUs. However, the methods used to obtain and prepare autologous PRP vary between the studies, thus further evidences are eagerly awaited. Adipose tissue-derived mesenchymal stem cells (ADSCs) are a promising tool in the treatment of DFUs, but additional largescale and long-term follow-up clinical trials are needed. Bone marrow mesenchymal stem cells (BM-MSCs) transplantation, on the other hand, revealed effective in reducing incidents and improving the quality of life of patients with amputations. Autologous Peripheral Blood Mononuclear Cells (A-PBMNCs) showed a good efficacy in the treatment of diabetic patients with CLI, but further RCTs are awaited to best investigate this new therapeutic approach. Photobiomodulation (PBM) therapy revealed effective in the treatment of DFUs in two RCTs, but a standardization of therapeutic protocols as well as level-I studies are needed.
