Use of topical recombinant human platelet-derived growth factor-BB (becaplermin) in healing of chronic mixed arteriovenous lower extremity diabetic ulcers

Abstract

Lower extremity ulcers cause significant morbidity and mortality in patients with diabetes. The primary factors that contribute to the development of this type of ulcer are peripheral neuropathy and peripheral vascular disease, which are often accompanied by infection. Lower extremity diabetic ulcers are chronic and difficult to treat, in part due to underlying pathologic conditions in individuals with diabetes that can contribute to impaired wound healing. This article reports the author's experience with treatment of chronic lower extremity ulcers of mixed etiologies with recombinant human platelet-derived growth factor--BB [rhPDGF-BB, REGRANEX (becaplermin) Gel 0.01%] in a patient with multiple risk factors including long-standing insulin-dependent type 2 diabetes.
