Nutritional Supplement on Wound Healing in Diabetic Foot
Clinical Effectiveness and Molecular Mechanisms of Nutritional Supplement on Wound Healing in Diabetic Patients With Limb-threatening Foot Ulcer
Diabetic foot ulcer (DFU) is the leading cause of non-traumatic limb loss in adult worldwide. One of the major causes of limb loss in patients with DFU is poor wound healing. It is known that nutrition plays a key role in wound healing, not only because of the required calories, but more importantly for collagen remodeling by specific amino acids (arginine, glutamine, and β-hydroxy-β-methylbutyrate).
Nevertheless, few studies have investigated nutritional supplements in patients with poor wound healing of DFU. Difficulties in assessing the severity of a wound and poor adherence to drug and food supplements at home may be important factors for the negative results shown in a most recent prospective randomized controlled trial. The diabetic foot center in Chang Gung Memorial hospital has extensive experience in caring for patients with limb-threatening DFU and we recently reported that poor nutritional status in our patients correlated to poor treatment outcomes. The aim of this study is to evaluate the clinical efficacy and possible molecular mechanisms in nutritional treatment for limb-threatening DFU. A total of 70 patients will be enrolled and randomized into study and control groups. All subjects will receive standard care. Additional amino acid supplements containing arginine, glutamine, and β-hydroxy-β-methylbutyrate or a control (high protein formula powder) will be given orally twice a day for 21 days, and the percentage change in wound size will then be measured. Complete healing time, recurrence or major adverse cardiac events will be recorded during one year of follow up. Data on wound size, nutritional status, and levels of matrix metallopeptidase (MMP)-2, MMP-9, nutrient molecules (measured by ABSOLUTE/DQ P180 KIT (LC MS/MS) will be recorded before and after the nutritional supplementation. In addition, the pioneer factor forkhead box protein A2 (FOXA2) that binds native chromatin and bookmarks genomic regions for transcriptional activity may play a role in nutritional supplements in acute stressed diabetic patients. Therefore, we intend to conduct a pilot study on the for FOXA2 gene in maintaining glucose homeostasis in diabetic foot patients after nutritional interventions.
