Background: Diabetic foot wound is an important health challenge throughout the world. Interleukin 8 (IL8) and macrophage-migration inhibitory factor (MIF) play a significant role in host defense and in wound healing. Immune perturbation and Vitamin D deficiency also contribute to nonhealing of diabetic foot wounds. We aimed to evaluate the serum concentration of IL8 and MIF in diabetic patients with and without foot infection and its association with Vitamin D status. Material and Methods: Serum concentrations of 25 dihydroxyvitamin Vitamin D and cytokines (IL8 and MIF) were measured by radioimmunoassay and enzyme-linked immunosorbent assay, respectively, from 100 subjects with diabetes and foot infection as cases and 73 subjects with diabetes without foot infection as controls. Data were presented as mean (± standard error of mean [SE]) unless otherwise indicated and were analyzed by SPSS 16.0. Results: There was no significant difference in the mean (±SE) of age, duration of diabetes, hemoglobin A1C, and body mass index between the two groups. The mean (±SE) concentration of IL8 was significantly higher and MIF was significantly lower in cases than controls. Vitamin D correlated negatively with IL8 (r = −0.191) and positively (r = 0.1) with MIF. However, only the former correlation was statistically significant (P = 0.01). IL8 was also significantly high in patients with severe Vitamin D deficiency (<10 ng/ml) compared to patients with Vitamin D more than 10 ng/ml. Conclusion: Serum concentration of IL8 is significantly higher in diabetic foot infections compared to controls. Severe Vitamin D deficiency was associated with IL8 concentration in patients with diabetes.
