Tabriz University of Medical Sciences, Tabriz, Iran, between 2014 and 2015 were recruited. Demographic and laboratory findings were recorded and all patients underwent clinical neurological examination and electrophysiologic studies.Results: According to electrophysiologic studies, DPN was found in 57.5% of patients including early stage of neuropathy (15%), mild sensory axonal neuropathy (25%), mild sensory motor axonal neuropathy (10%), and moderate sensory motor axonal neuropathy (7.5%). Age, duration of diabetes, fasting blood sugar, and glycosylated hemoglobin levels had no significant difference between patients with and without DPN. Reduced deep tendon reflexes were observed in the upper limb (30%) and lower limb (47.5%) of patients, which were both significantly higher in DPN patients (upper limb [p=0.03] and lower limb [p=0.04]). The most frequent electrophysiologic findings were unobtainable H-reflex, low amplitude sural, and median sensory responses.Conclusion: Subclinical DPN is a common complication found in children and adolescents with TIDM and peripheral sensory axonal neuropathy is the most frequent type. Nerve conduction study is recommended for early detection of DPN and prevention of its progress.
