Abstract:
Abstract Autonomic neuropathy, although often reported to occur in patients with AL (amyloid of light chain of immunoglobulin) amyloidosis, is extremely rare in AA (amyloid A) amyloidosis. We describe a patient with AA amyloidosis secondary to rheumatoid arthritis (RA) in whom autonomic neuropathy resulted in gustatory sweating during the end stage of RA. We discuss the importance of gustatory sweating as a characteristic sign of autonomic nervous system dysfunction in AA amyloidosis secondary to RA, and stress the availability of cardiovascular autonomic tests as an indicator of autonomic neuropathy in not only AL amyloidosis but also AA amyloidosis.
