Abstract:
This study determined the prevalence of diabetic peripheral neuropathy (DPN) and subclinical DPN (sDPN) in patients with type 2 diabetes mellitus (T2DM) using nerve conduction study (NCS) as a diagnostic tool.We also investigated the factors associated with the development of sDPN and compared factors between the sDPN and confirmed DPN (cDPN).This cross-sectional study involved 240 T2DM patients who were successively admitted to the endocrinology wards of Wuhan Union Hospital over the period of January to December 2014.Data on the medical history,physical and laboratory examinations were collected.DPN was diagnosed using NCS.One-way ANOVA with least significant difference (LSD) analysis or chi-square tests was used to compare parameters among DNP-free,sDPN and cDPN patients.Independent factors associated with sDPN were determined using logistic regression.The results showed that 50.8％ of the participants had DPN,and among them,17.1％ had sDPN.sDPN showed significant independent associations with age,height,HbA1c,presence of atherosclerosis and diabetic retinopathy.Patients with DPN differed significantly from those without DPN with respect to age,duration of disease (DOD),HbA1c,presence of atherosclerosis,diabetic retinopathy,nephropathy and hypertension.Patients with cDPN,relative to those with sDPN,had significantly longer DOD and higher prevalence of peripheral artery disease (PAD) and coronary artery disease (CAD).Our study suggests that a significant number of T2DM patients are affected by sDPN,and the development of this condition is associated with advanced age,tall stature,poor glycaemic control,presence of diabetic retinopathy and atherosclerosis.On the other hand,patients with cDPN tend to have a longer DOD and are more likely to suffer from PAD and CAD.
