Etiology and pathogenesis in fibromyalgia have not been fully elucidated. Many mechanisms contribute to the formation of FMS. Many evidence has been found for dysfunction of the central and autonomic nervous system, immune system, cytokines, neurotransmitters and hormones, which are thought to play a role in the disease. Since increasing systemic inflammation is thought to have a role in the etiopathogenesis of FMS, there are increasing numbers of studies focusing on this aspect of fibromyalgia. Neutrophil / lymphocyte ratio (NLR) and platelet / lymphocyte ratio (PLR) in peripheral blood are simple markers of systemic inflammatory response. Another factor thought to have a role in etiopathogenesis is autonomic nervous system dysfunction. It has been found that there is autonomic dysfunction in the sympathetic nervous system in patients with FMS. Sympathetic skin response measurements are frequently used electrophysiological methods to evaluate the functionality of the sympathetic nervous system, which is a component of the autonomic nervous system. In addition, vitamin D deficiency is common in FMS patients. In a study, inadequate vitamin D levels were found in 45% of fibromyalgia patients. When a literature review is performed, it is seen that electrophysiological studies are performed to evaluate autonomic dysfunction in patients with fibromyalgia. No studies were found showing the relationship between vitamin D levels and inflammatory parameters in patients with fibromyalgia and electrophysiological findings. In our study, it was aimed to compare the autonomic dysfunction of fibromyalgia patients with healthy volunteers by electrophysiological evaluation and to investigate the relationship between vitamin D levels and inflammatory parameters in fibromyalgia patients and the data obtained from electrophysiological studies. In this way, we aimed to contribute to a better understanding of the physiopathology of fibromyalgia patients with autonomic dysfunction.
