Familial Mediterranean Fever (FMF) is the most common inherited autoinflammatory disease affecting 150,000 patients worldwide. Periodic febrile exacerbations, peritonitis, and pleuritis are characteristic disease features. Dysregulation of IL-1β secretion has an important role in the pathophysiology of the disease, and IL-1β also serves as a therapeutic target. Chronic inflammation has been associated with early atherosclerotic and cardiovascular disease in various rheumatic diseases. An increased risk for cardiovascular events associated with disease activity has been described in rheumatoid arthritis, psoriatic arthritis, and systemic lupus erythematosus. In addition, autonomic nervous system dysfunction may contribute to increased cardiovascular risk in patients with inflammatory disease. For example, decreased heart rate variability is an important feature of cardiac autonomic dysfunction and is an isolated risk factor for cardiovascular events. Autonomic dysfunction studies related to FMF have conflicting results. The aim of this study was to determine autonomic dysfunction symptoms and objective findings in patients with FMF; Demographic characteristics, disease characteristics, inflammatory burden, fatigue level, sleep quality, presence of fibromyalgia and their relationship with quality of life were evaluated and compared with healthy controls.
