Diabetic kidney disease (DKD) is the most common cause of end-stage renal disease (ESRD). The incidence of diabetes worldwide is increasing, hence the incidence ofDKDis also increasing.Several previous studies suggested that there may be a relationship between appearance of diabetic peripheral neuropathy (DPN) and impairment of kidney function.
The primary aim of this study was to evaluate the correlation between peripheral nerve conduction study parameters and urinary albumin excretion (UAE) level in diabetic patients. This is a cross-sectional studyperformed in 37 patients with diabetes. After the study, we identified asignificantnegative correlation between level of UAE and action potential (AP), and between level of UAE and nerve conduction velocity (NCV) of motor nerves (R = - 0.33 to R = - 0.65, p < 0.05). We also found asignificantnegative correlation between level of UAE and NCV ((R = - 0.36 to R = - 0.48, p < 0.05), and a significantpositive correlation between level of UAE and DSL (R = 0.37 to R = 0.74, p < 0.05) of sensory nerves.
Our results suggested that the presence of microvascular diabetic complications aresimultaneous, and the earliest presence is the DPN, especially abnormal NCSparameters. This could be a recommendation for the endocrinologist and nephrologist in early detection and treatment of DKD. We suggest that the peripheral NCS should be routinelyscreened for microvascular complications in diabetic patients.
