“…In other patients, it may occur in the context of systemic autoimmune disease [3,4], and autonomic neuropathy may be the initial manifestation of Sjogren syndrome [5] or the antiphospholipid syndrome [6], which may coexist. Dysautonomia may also occur in association with most other autoimmune diseases, including some cases of Hashimoto thyroiditis [4], rheumatoid arthritis, [7] spondyloarthropathy [8], lupus [9], systemic sclerosis [10], celiac disease [11], inflammatory bowel disease [12], myasthenia gravis [13], and multiple sclerosis [1]. Indeed, it has been hypothesized that autonomic dysregulation may be involved in the etiopathogenesis of systemic autoimmunity as a result of the complex interactions between the immune system and the autonomic nervous system [14].…”
