Evaluation of the skin condition examination for the detection of lower extremity peripheral arterial disease among patients with diabetes mellitus

Abstract

 Objective：We assessed the value of the skin color and morphology in the detection of lower extremity peripheral arterial disease（PAD）in diabetic subjects. Methods：Setting：A advanced treatment hospital in Japan. Participants：32 outpatients with diabetes mellitus. Measurements：The presence of PAD defined as combination with ankle brachial index and thermography. Lower extremity skin condition was evaluated by skin color and skin morphology. Results：The skin variables, a and b were significantly associated with lower extremity PAD. a showed the area under the receiver operating characteristic curve of 0.706. a＜2.80（sensitivity 78.6%, specificity 55.6%）had the large positive likelihood ratio. Conclusions：The skin color with lower extremity PAD in diabetic patients had dark red color skin.
