A comprehensive study on effect of recombinant human epidermal growth factor gel in diabetic foot ulcer

Background: Ulcer healing in the diabetic patients is challenging due to a prolonged inflammatory response, extracellular matrix degradation irregularities, and increased bacteria presence. Recombinant human epidermal growth factor (REGEN-D 150), which was cloned and over expressed in E. coli, has shown enhanced healing of chronic diabetic foot ulcers (DFU) by significantly reducing the duration of healing in addition to providing excellent quality of wound healing and re-epithelization. Aim: To compare the efficacy and safety of collagen granule dressings and conventional dressing in deep wounds in terms of reduced healing time, number of dressing, healing quality and complications. Materials and methods: Thirty patients with foot ulcer were evaluated. A recombinant human Epidermal growth factor gel or conventional dressings were applied, and the patients were followed as per standard post-application treatment protocol. Patients underwent dressing changes every day until wound healing or for maximum period of 12 weeks. Changes in wound size were recorded when the dressing was removed; and at 4 and 12 weeks. Results: Common age groups were 41-50 and 51-60 years of age. Complete healing was present in 12 cases. Conclusion: There was statistically significant difference between the results of Recombinant human epidermal growth factor gel and saline dressings as collagen dressings had better healing response rate as compared to placebo when given along with standard treatment of diabetic foot ulcer.
