Diabetes is the leading cause for non-traumatic amputations and hospitalization. Current treatments are challenging, lengthy, costly and associated with failure to heal and relapse. In recent years emphasis has been directed at using low level laser therapy (LLLT), or phototherapy, to accentuate cellular processes to contribute to more efficient resolution of wound healing. This study aimed to determine the effects of laser irradiation on diabetic wound healing. An in vitro diabetic wound model was irradiated with visible red (636 or 632.8 nm) and near infra-red (830 nm) light at a fluence of 5 J/cm2. Various cellular and molecular events were evaluated post-irradiation. A pilot study was also conducted on chronic ulcers in diabetic patients using a combination of red and infra-red light. Patients were treated twice a week for a maximum of 12 weeks with standard podiatric care and phototherapy. In vitro studies showed that laser irradiation stimulated cellular viability and proliferation, and increased collagen production. Treating patients with LLLT in combination with standard treatment of care was advantageous over treating ulcers with podiatric methods alone, and some ulcers resolved completely within 8 weeks. It is evident that a combination of conventional podiatric intervention and phototherapy has the ability to improve wound regeneration. Phototherapy can be an important tool in speeding up the healing process as well as alleviating pain and inflammation. There is a need to study the underlying mechanisms involved in LLLT so that this form of therapy, which has no reported side-effects, can be used as an adjunctive therapy for the treatment of diabetic ulcers.
