[Autonomic dysfunction in metabolic diseases].

Abstract
Among many metabolic disorders, porphyrias and Fabry disease are known to affect autonomic nervous system. In patients with acute intermittent porphyria, hereditary coproporphyria, and variegate porphyria, autonomic symptoms such as abdominal pain, vomiting, hypertension and tachycardia are among the most prominent clinical manifestations. Fabry disease is clinically characterized by severe limb pain, hypohidrosis, angiokeratomas and various autonomic symptoms. In both porphyrias and Fabry disease, pathological changes in the central and peripheral autonomic nervous system have been documented. In porphyrias, a loss of myelinated fibers, axonal degeneration, and segmental demyelination in peripheral autonomic nerves as well as chromatolysis of several brain stem nuclei have been found. In Fabry disease, abnormal amount of the substrates of alpha-galactosidase, i.e. ceramide di- and trihexoside, are found to be accumulated in the central and peripheral autonomic nerves.
