Abstract
UNLABELLED
The aim of this study was to investigate the role of Sudoscan asymmetry parameters in the diabetic foot.
PATIENTS AND METHODS
In this study we included 165 participants: 84 type 2 diabetes patients divided into three HbA1c matched groups - group 1: newly diagnosed diabetics (n = 31), group 2: people with longer diabetes duration and established neuropathy (n = 33), group 3: patients with diabetic foot ulcer (n = 20), and a control group of 81 people with prediabetes. All subjects underwent peripheral sudomotor evaluation using Sudoscan device (Impeto Medical, Paris).
RESULTS
Patients with diabetic foot had significantly higher Sudoscan feet asymmetry (19.6%) compared to those with only diabetic neuropathy (7.9%), compared to the group with newly diagnosed diabetes (7.44%), and compared to controls (2.5%). This test has shown a good discriminative value (with a threshold of 9.5%) for diabetic foot with area under the ROC curve of 0.955 (p = 0.001). Additionally, in a regression model feet asymmetry proved its predictive value for participants with diabetic foot.
CONCLUSION
In this study Sudoscan feet asymmetry proved to be a novel discriminator and predictor for diabetic foot patients. It might be considered as a marker for early damage in the neuropathy evaluation protocol.
