Investigation of Estrogen Receptor 1 Gene Polymorphism Frequency in Patients With Fibromyalgia Syndrome

Nigde Omer Halisdemir University·observational·Posted Dec 26, 2018·Updated Sep 1, 2021

In Brief

An observational study evaluating ACR 1990 fibromyalgia critters for Fibromyalgia. Completed, enrolled 200 participants across 1 site.

Detailed Summary

Fibromyalgia Syndrome (FMS) is a chronic musculoskeletal disorder accompanied by diffuse body pain, increased fatigue and tenderness in specific anatomical regions, and sleep disturbance. The higher prevalence of FMS in women and the observation of it from young adulthood suggest the effect of sex hormones on the pathophysiology of this condition. Steroid hormones, especially estrogen, have effects on both the peripheral and central nervous system receptors (estrogen receptor-a \[ERa\] and estrogen receptor-b \[ERb\]), on the inflammatory process, and on central pain delivery. However, the mechanism of action of these hormonal effects is still unknown and is a matter of debate. The fact that fibromyalgia syndrome and migraine are more common in women of reproductive age and their incidence is higher than other populations suggests that these two diseases may have a common genetic basis. Previous studies have shown that ESR-1 594G\> A (rs2228480), ESR-1 325C\> G (rs2295190) polymorphisms significantly increase the risk of migraine occurrence. However, there are no studies investigating these polymorphisms in FMS. In this study, it was aimed to investigate whether there is a relationship between ESR-1 594G\> A (rs2228480) and ESR-1 325C\> G (rs2295190) polymorphisms and fibromyalgia disease.
