[Diabetic thoracoabdominal neuropathy. Clinical and electrophysiological study with evaluation of the autonomic nervous system].
We report on eight patients with diabetic thoracoabdominal neuropathy in whom careful evaluation of peripheral and autonomic nervous system function was performed. All patients had non insulin-dependent diabetes mellitus of 10.5 +/- 6.7 years mean (+/- SD) known duration with poor glycemic control. Thoracic (n = 7) or abdominal (n = 1) pain of sudden onset involved several adjacent dermatomal segments and was bilateral and asymmetrical in 7/8 patients. Four patients had hypoesthesia in the painful zone and six presented with significant weight loss (6.2 +/- 4.3 kg) which reversed after the relief of pain. Truncal electromyogram was abnormal in 7/7 patients. Nerve damage was not limited to thoracic nerves since electrophysiological studies evidenced distal polyneuropathy in all patients. The autonomic nervous system was also involved. Sympathetic skin response was abnormal in 7/7 patients and autonomic cardiovascular function tests demonstrated cardiac denervation in 5/5 patients. In 4/4 patients a marked relief of pain was noted within one week with amitriptyline treatment. This report confirms the characteristic clinical presentation of diabetic thoracoabdominal neuropathy. Moreover, it suggests that this neuropathy is part of a diffuse damage that also involves peripheral nerves of the limbs and autonomic nervous system.
