Intralesional epidermal growth factor for diabetic foot wounds: The first cases in Turkey

Background: Intralesional recombinant epidermal growth factor (EGF) was produced in the Centre for Genetic Engineering and Biotechnology (CIGB), Cuba, in 1988 and licensed in 2006. Because it may accelerate wound healing, it is a potential new treatment option in patients with a diabetic foot wound (whether infected or not) as an adjunct to standard treatment (i.e. debridement, antibiotics).We conducted the initial evaluation of EGF for diabetic foot wounds in Turkey. Methods: We enrolled 17 patients who were hospitalized in various medical centers for a foot ulcer and/or infection and for whom below the knee amputation was suggested to all except one. All patients received 75 mg intralesional EGF three times per week on alternate days. Results: The appearance of new granulation tissue on thewound site (?75%) was observed in 13 patients (76%), and complete wound closure was observed in 3 patients (18%), yielding a ‘complete recovery’ rate of 94%. The most common side effects were tremor (n=10, 59%) and nausea (n=6, 35%). In only one case,a serious side effect requiring cessation of EGF treatment was noted. That patient experienced severe hypotension at the 16th application session, and treatment was discontinued. At baseline, a total of 21 causative bacteria were isolated from 15 patients, whereascultures were sterile in two patients. The most frequently isolated species was Pseudomonas aeruginosa. Conclusion: Thus, this preliminary study suggests that EGF seems to be a potential adjunctive treatment option in patients with limb-threatening diabetic foot wounds. © 2015 Bulent M. Ertugrul et al
