Intralesional epidermal growth factor therapy fordiabetic foot ulcers: an evaluation of 15 cases

Background/aim: Intralesional recombinant epidermal growth factor (EGF) is a new treatment approach for diabetic foot ulcer, approved in 2006. EGF therapy is given as an adjunct to the standard treatment regimen of antibiotics, surgery, and hyperbaric oxygen. EGF accelerates the healing of diabetic foot ulcers and reduces healing time. This single-center study was conducted to evaluate the outcomes of intralesional EGF therapy in patients with diabetic foot ulcers.Materials and methods: We present the data of the follow-up patients treated in our clinics. Fifteen patients with diabetic foot ulcers or infections, who had been followed up and treated in our clinics, were included in this retrospective study. All patients were administered intralesional injections of 75 μg of EGF after treatment for infection on their diabetic foot ulcers, three times a week on alternate days. The patients were monitored with respect to treatment response and side effects of EGF.Results: Thirteen patients (86.7%) developed new granulation tissue, 10 patients (66.7%) had complete wound closure, and three patients (20%) showed partial wound closure. No serious side effects requiring discontinuation of EGF therapy were observed. A total of twenty-one bacterial agents were isolated in thirteen patients, and no bacterial growth was observed in the tissue cultures of two patients. Pseudomonas aeruginosa was the most common isolated infectious agent in the tissue cultures (n: 6, 28%). Conclusion: Intralesional injection of EGF on top of the standard treatment regimen appears to be a useful adjuvant therapy option in selected patients.
