The role of nerve growth factor in the prophylaxis and treatment of diabetic foot ulcers.

Abstract

Diabetic foot ulcers are still particularly difficult to heal. Therefore, preventing and therapeutic adjuncts are increasingly being explored. Nerve growth factor (NGF) is a promising agent exhibiting beneficial actions on both diabetic peripheral neuropathy, one of the main causes of foot ulcers, and on ulcer healing. Indeed, preclinical research in animal models of diabetes has revealed the trophic effect of NGF on small C-fibres, while phase 2 human trials have provided evidence for a favourable effect on sensory neuropathy. However, the results of a phase 3 trial were moderate and, therefore, not enough to encourage widespread use of NGF in the treatment of diabetic neuropathy. Available literature on the role of NGF on diabetic wound healing is sparse but encouraging. Exogenous supplementation of NGF or the use of alternative techniques to increase its endogenous expression could emerge as a protective and therapeutic modality for diabetic foot ulcers in addition to standard treatment and other growth factors. The present review provides an outlook on the role of NGF in the prophylaxis and treatment of diabetic foot ulcers.
