Study of Vitamin D Status in Patients Suffering from Diabetic for Ulcer Cured in Medical Centers of Hamedan

Abstract
Foot ulcer is one of the most important effects of diabetes which appears as wounds or ulcers on the foot; and it leads to amputation in case of lack of treatment at the end. Besides all the documents about the role of vitamin D in diabetes pathophysiology, some others have been reported recently about its role in controlling the effects such as diabetic foot. The aim of this study is to investigate the status of vitamin D in people suffering from diabetes and have diabetic foot. Materials and methods: This is a descriptive and cross-sectional study in which 140 patients suffering from diabetic foot ulcer have participated in Hamedan. Serum 25 hydroxy vitamin D has been measured by immunofluorescence method. In this study, vitamin D deficient of serum is defined as 25 hydroxy vitamin D less than 29 ng/ml, and amounts of 21-29 ng/ml are considered as insufficient vitamin D. Findings: The average of vitamin D serum level in these patients was 19.9 ng/ml. 73.6 % of these patients had vitamin D deficient and 12.9 % of them had insufficient vitamin D serum level, and in fact, only 24 % of patients had the natural amount of vitamin D. Conclusion: Findings of this study have shown that the prevalence of vitamin D deficiency in patients suffering from diabetic foot ulcer is high, therefore, it is needed to investigate the status of vitamin D in these patients; and in case of deficiency, essential actions must be taken to compensate.
