摘要
Diabetic neuropathy, the most common form of peripheral neuropathy, presents as different forms of focal or diffuse neuropathy, including the disabling, or potentially life-threatening clinical entities of painful diabetic neuropathy, autonomic neuropathy, and diabetic foot. The pathogenesis of diabetic neuropathy results from the concurrent action of various intersecting factors of nerve damage, such as oxidative stress and mitochondrial dysfunction, inflammation, microangiopathy and ischemia, triggered by hyperglycemia and related biochemical changes. Symptomatic treatment of diabetic neuropathy mainly concerns therapies for neuropathic pain, interventions targeted at the organ systems involved in autonomic neuropathy, and management of diabetic foot. Therapeutic approaches to the pathogenesis of diabetic neuropathy have focused on the different components of the causes of nerve damage, particularly oxidative stress, which has been demonstrated to play a central role. Alpha-lipoic acid, a potent lipophilic free radical scavenger, has been used in treatment of patients with diabetic neuropathy, displaying efficacy on the chief symptoms, including neuropathic pain, and showing that neuropathic deficits may be improved by treatment. Current evidence suggests a possible efficacy of alpha-lipoic acid not only for neuropathic symptoms, but also for reducing the risk factors for diabetic neuropathy.
