Isolated Autonomic Cardiovascular Neuropathy in a Patient with Primary Sjögren Syndrome: A Case of Successful Treatment with Glucocorticoid

ABSTRACT Autonomic failure is rare in patients with Sjogren syndrome (SS). We report the case of a 46-year-old woman with severe autonomic cardiovascular failure, manifested by incapacitating postural hypotension, as the first symptom of primary SS. Treatment with glucocorticoid resulted in a dramatic improvement of her symptoms and objective findings of autonomic cardiovascular dysfunction. We suggest that SS should be considered in patients with idiopathic autonomic cardiovascular neuropathy, especially in those with idiopathic orthostatic hypotension. Furthermore, glucocorticoid therapy seems to be very efficacious in the treatment of SS-associated autonomic cardiovascular neuropathy.
