Abstract

PURPOSE
Diabetic foot ulcer is a representative disease of chronic would with multiple defects of wound healing factors. Many nutrition factors have been known to be essential for wound healing, but objective data are lacking. The purpose of this study is to determine those factors essential for wound healing, and to find out which of those factors are lacking in diabetic foot ulcer patients through this pilot study. METHODS: We studied 100 patients who visited our clinic from March 2005 to February 2006 for treatment of diabetic foot ulcers with a duration of more than 6 weeks. We checked serum levels of protein, albumin, vitamin A, C, E, iron, magnesium, zinc, copper and hemoglobin by drawing 23cc blood after 8 hours of fasting. Protein, albumin, iron, magnesium levels were measured by colorimetry; hemoglobin levels were measured by auto analysis. Vitamin levels were measured by high performance liquid chromatography (HPLC), copper and zinc levels were measured by Inductively coupled plasma (ICP). They were compared with normal values. The patients were divided by transcutaneous oxygen pressure levels, age and sex to study the effects of these parameters.
RESULTS
76% and 61% of patients had within-normal range serum protein and albumin levels, respectively. Among vitamins, only the level of vitamin C was low in 55% of the patients. Levels of vitamin A, E were normal or high in 93% and 100% of patients. As for trace elements, levels of iron and zinc were low in 63% and 60% of patients, but levels of magnesium and copper were usually normal or high. Levels of vitamin C, iron and zinc were lower in the low-transcutaneous oxygen pressure group. There were no definite differences according to age and sex.
CONCLUSION
Serum levels of Hb, vitamin C, iron, zinc were low in most diabetic foot ulcer patients. The deficit was very severe in the low-transcutaneous oxygen pressure group.
