The Effect of Kiwifruit Therapeutics in the Treatment of Diabetic Foot Ulcer.

Diabetes mellitus is considered a silent disease with possible late chronic complications such as diabetic foot ulcer. This condition is managed by surgical debridement. To improve surgical outcome, some surgeons use proteolytic agents after surgery. Kiwifruit contains a type of proteolytic enzyme called actinidin that may play a role in the treatment of such complication. In the current study, we evaluate the role of kiwifruit extract in the treatment of diabetic foot ulcer. Eighteen diabetic foot ulcer patients were included in a randomized, double-blind clinical trial. The patients were divided randomly to control and experimental groups. Patients in the control group underwent daily wound dressing using base ointment (Eucerin). In the experimental group, we added kiwifruit extract to the standard wound dressing. Clinical data including general appearance of wound (according to recorded photographs before and after medical intervention) were analyzed using SPSS version 22. The mean wound area of the experimental group was significantly less than in the control group ( = .005) after 4 weeks of treatment. Comparison of the average of size difference, before and after the treatment in the experimental group and the control group, shows that kiwifruit can have a good impact on wound healing ( = .0001). In patients with diabetic foot ulcer, wound dressing using kiwifruit extract may help reduce time of treatment and may replace surgical debridement for some selected cases.
