Sleep disorders in Venezuelan fibromyalgia patients

Abstract

Sleep disorder is thought to be responsible, at least in part, for poor neurocognitive outcomes in much pathology while obstructive respiratory events are associated. Fibromyalgia (FM) patients report early morning awakenings, awakening feeling tired or unrefreshed, insomnia, as well as mood and cognitive disturbances; they may also experience primary sleep disorders including sleep apnea. FM is a chronic condition characterized by widespread pain and associated with symptoms like fatigue, irritable bowel, sleep disorder, chronic headaches, jaw pain, cognitive or memory impairment, sleep disorders etc. However, polysomnography study was not used as a routine diagnosis methodology in FM patients. The aim of this study was to evaluate the value of the polisomnography studies to diagnose sleep disorder in Fibromyalgia patients. We evaluated 194 FM patients who assisted to Neurological and Neurosciences Institute, Caracas, Venezuela, by a multidisciplinary team work, we performed physical exam including ACR criteria for fibromyalgia diagnosis, neurological and cognitive evaluation, Hamilton depression and anxiety scales, visual analogical pain scale. Sleep disruption or fragmentation was evaluated with a polysomnography study. The mean age of patients was 48.39 + 13.75. According to American academy of sleep medicine we found that all FM patients had sleep disruption. 31.38 had sleep disorder related to their medical condition, 23.19 had sleep apnea and 45.43 has restless legs syndrome (RLS). We found a correlation ( p = 0.069) between sleep efficiency and awake. We also found that moderate to severe apnea was found in 26% of FM patients.The median value of PLM in sleep of FM patients was 84.31. It is important to note that 100% of FM patients had non reparatory sleep and sleep disorder was present first than the other FM symptom. Our data confirm that sleep disruption had been consider as one of the main symptoms in the criteria of FM patients according to the new criteria of Americam college of reumathology. INNAP PERSONAL.
