Brief summary
The overall aim of this study was to assess the effects of nutritional supplementation and education on the healing of foot ulcers in diabetic patients. The hypothesis was that improving dietary intake can promote wound healing by improving nutritional status, blood flow, and decreasing inflammatory biomarkers while increasing anti-inflammatory factors.
Interventions
DIETARY_SUPPLEMENTglucose control nutritional shake, nutrition education
Participants in the treatment group were educated about improving their diet by consuming more low-fat high-quality protein sources, vegetables, complex carbohydrates and less simple carbohydrates. They were also instructed to consume two servings (474 ml) of a commercially produced Glucose Control Nutritional Shake between meals throughout the day for 12 weeks or until complete healing. The supplements provided a total of 500 kilocalories, 28 grams of high-quality protein and essential vitamins and minerals.

| Change in inflammatory biomarkers | 12 weeks | Mean change from baseline in c-reactive protein(ng/ml), interleukin 6(pg/ml), interleukin 10(pg/ml), and tristetraprolin(pg/ml) at weeks 4, 8, and 12 |
| Change in lean body mass and body fat | 12 weeks | Mean change from baseline in lean body mass(lb) and body fat(lb) at weeks 4, 8, and 12 |
| Change in dietary intake of nutrients | 12 weeks | Mean change from baseline in dietary intake of energy(kcal), protein(g), vitamin C(mg), vitamin E(IU), vitamin A(IU), Zinc(mg), Copper(mg), and Manganese(mg) at weeks 4, 8, and 12. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in basal metabolic rate | 12 weeks | Mean change from baseline in basal metabolic rate(kcal) at weeks 4, 8, and 12. |
| Change in Ankle Brachial Index(ABI) | 12 weeks | Mean change from baseline in ABI by comparing the blood pressure in the upper and lower limbs at weeks 4,8, and 12. |
| Length of time that a wound achieves complete wound closure | 12 weeks | Duration (number of days) to achieve complete wound closure from baseline assessed between both groups. |
