Clinical and electrophysiological signs of diabetic polyneuropathy -- effect of glycemia and duration of diabetes mellitus.
Diabetic polyneuropathy occurs in around 50% of diabetic patients. Its pathophysiological mechanism is not completely clarified and major occurrences boil down to the change in neural phenotype and vasa nervorum. As glucose neurotoxicity has been suggested by plenty of evidence, the aim of the study was to assess the effect of glycemia on the severity of diabetic polyneuropathy. ⋯ Diabetes duration was associated with a growing number of sensory symptoms, among which the sensation of pain similar to electric shock was present in 63% of patients. In addition, it also had negative impact on the sensory and motor nerve conduction velocity. HbA1c influenced the whole range of electrophysiological indicators of diabetic polyneuropathy.
