An enzyme known as neuron-specific enolase becomes elevated in diabetes patients and even higher in those suffering from diabetic neuropathy, according to a study conducted at Nanjing Medical University in China. The association is independent of the patient's glycemic state, age, sex or kidney function. "This may provide a potential blood marker for diabetic neuropathy," said Nanjing lead researcher Dr. Li Jianbo. Although diagnostic tools for diabetic neuropathy exist, there are as yet no specific biomarkers specifically for neural damage.
