Immunomodulatory treatment in postural tachycardia syndrome: A case series

Postural tachycardia syndrome (POTS) is a form of autonomic dysfunction characterized by symptoms of orthostatic intolerance, often accompanied by sudomotor dysfunction and gastrointestinal dysmotility. Recently, evidence has accumulated that in a subset of patients, the pathogenesis of dysautonomia may be immune‐mediated. The aim of the current report was to evaluate the use of intravenous immunoglobulin (IVIG) treatment in patients with progressive and/or refractory immune‐mediated POTS.
