Abstract:

Worldwide, approximately 463 million people are estimated to suffer from a form of diabetes mellitus, with diabetic neuropathy being one of its most common complication. Using streptozotocin to induce diabetes in C57BL/6J mice, we assess the neuroprotective role of alpha thioctic acid and vitamin B complex in diabetic neuropathy. In order to highlight the peripheral nerve changes produced by diabetes, we performed an electroneurographic recording of the animals and compared the amplitude of the compound muscle action potential (CMAP). Treatment with alpha thioctic acid (A), or vitamin B complex (B), or A+B caused a smaller decrease in CMAP amplitude than if these therapies had not been applied. On the other hand, we found that in group A+B a smaller decrease of CMAP amplitude was observed compared to the control group (6 weeks after the onset of diabetes p<0.0001). Also, separate treatment with alpha thioctic acid alone caused a smaller decrease in CMAP amplitude compared to the control group (6 weeks after the onset of diabetes mellitus p<0.0436), but also separate treatment with vitamin B complex alone resulted in a smaller decrease of CMAP amplitude compared to the Control group (6 weeks after the onset of diabetes p<0.0070). The combined therapy with alpha thioctic acid and vitamin B complex has a greater effect in preventing axonal degeneration in diabetic neuropathy than the single therapy only with alpha thioctic acid or only with vitamin B complex.
