[Diabetic neuropathy: therapeutic nihilism is no longer acceptable]

The repeatedly expressed doubts about the value of an effective therapy for diabetic neuropathies are no longer acceptable. Today a number of excellent longitudinal and cross-sectional studies, i.e. DCCT, Steno 2, DCCT/EDIC, European Diabetes Prospective Complications Study, are available. The attending physician should make every effort to diagnose diabetic neuropathies as soon as possible with all their multivarious manifestations. Treatment must be promptly, aggressively and multifactorially as described in evidence-based guidelines. In principle, the same risk factors apply to neuropathy in type 1 and type 2 diabetes as for macro-angiopathy and microangiopathy. Therapy focuses on establishing near-normal diabetes and blood pressure control, lipid management, intensive patient education, avoidance of exogenous noxae such as alcohol and nicotine and if necessary, an effective therapy of neuropathic pain. The objective of all diagnostic and preventive efforts must be always to avoid the development of the diabetic neuropathic foot syndrome, which is the most important end stage of somatic and autonomic diabetic neuropathy.
