BACKGROUND
EZSCAN is a new, noninvasive technique to detect sudomotor dysfunction and thus neuropathy in diabetes patients at an early stage. It further predicts chances of development of other microvascular complications. In this study, we evaluated EZSCAN for detection of microvascular complications in Type 2 diabetes patients and compared accuracy of EZSCAN with standard screening methods.
MATERIALS AND METHODS
104 known diabetes patients, 56 males and 48 females, were studied. All cases underwent the EZSCAN test, Nerve Conduction Study (NCS) test, Vibration perception threshold test (VPT), Monofilament test, Fundus examination and Urine micral test. The results of EZSCAN were compared with standard screening methods. The data has been analysed and assessed by applying appropriate statistical tests within different groups.
RESULTS
Mean age of the subjects was 53.5 ± 11.4 years. For detection of diabetic neuropathy, sensitivity and specificity of EZSCAN was found to be 77.0 % and 95.3%, respectively. Odd’s ratio (OR) was 68.82 with p < 0.0001. AUC in ROC curve was 0.930. Sensitivity and specificity of EZSCAN for detection of nephropathy were 67.1% and 94.1%, respectively. OR = 32.69 with p < 0.0001. AUC was 0.926. Sensitivity of EZSCAN for detection of retinopathy was 90% while specificity is 70.3%. OR = 21.27; p< 0.0001). AUC came out to be 0.920.
CONCLUSION
Results of EZSCAN test compared significantly to the standard screening methods for the detection of microvascular complications of diabetes and can be used as a simple, noninvasive and quick method to detect microvascular complications of diabetes.
