Diabetes Peripheral Neuropathy and Small-fibre Nerve Damage: A Comparative Study

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01160887

Brief Summary:
The purpose of this study is to investigate whether patients with diabetes-related peripheral neuropathic pain also have non-recognized damage to the intestine caused by autonomic neuropathy. The model will shed light on aspects of peripheral nerve injuries on both somatic and as well as visceral sensory nerves. Classical autonomic parameters from electrocardiography (ECG) and Holter (24-h ECG and blood pressure) are compared with peripheral nerve injuries. The damage of autonomic nerves often recognized late in the course when patients develop gastroparesis, however an earlier recognition of this nerve damage may help clarifying the fundamental pathomechanisms and thereby optimize treatment for this patient group in the future.
