ABSTRACT
BACKGROUND: Sleep disturbances such as nonrestorative sleep and nighttime awakenings play a crucial role in fibromyalgia (FMS). Pain and sleep disturbances show a bidirectional relationship which affect outcomes in FMS. This study aims to compare sleep structures between patients with fibromyalgia and healthy controls. METHODS: We evaluated subjective and objective sleep structures of 33 patients with fibromyalgia and 34 healthy controls using the Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, and polysomnography. Student's T test, chi-square, discriminant analysis, the Kruskal-Wallis, and Mann-Whitney U test were used for statistical analysis. RESULTS: Patients with FMS reported poorer sleep quality than controls (p = 0.003). Polysomnography data showed patients with FMS exhibited a greater number of awakenings (p = 0.01), more arousals (p = 0.00), higher arousal index (p = 0.00), greater apnea hypopnea index (p = 0.03), and less N1 sleep (p = 0.02) than healthy controls. The discriminant analysis revealed that number of arousals, arousal index, and N1 sleep were able to distinguish patients with FMS from healthy controls with 78.5% accuracy. Twelve of the 33 patients with FMS were diagnosed with obstructive sleep apnea syndrome (OSAS). When we excluded patients with OSAS, a statistically significant difference was maintained. CONCLUSIONS: Our findings may explain the deterioration of subjective sleep, symptoms as unrefreshing sleep, fatigue, and pain in patients with FMS. Despite similar clinical manifestations, patients with FMS should be evaluated for OSAS due to treatment differences. The role of sleep alterations in the clinical manifestation and severity of FMS suggest that effective treatments to improve sleep quality may lead to more effective management of FMS.

We aimed to investigate the changes in the objective and subjective sleep variables during painful episodes of fibromyalgia and post-episode period, and to evaluate the impact of the sleep variables on the current clinical, psychological, and immunologic parameters. Thirty-one consecutive patients who were referred to the Erenköy Physical Therapy and Rehabilitation Polyclinic with a diagnosis of fibromyalgia were evaluated before and in the sixth week of the acute pain treatment. The sleep variables were measured by polysomnography, Pittsburgh Sleep Quality Index, and Epworth Sleepiness Scale. The clinical and psychiatric assessment of patients was performed by using Fibromyalgia Impact Questionnaire; Patient Health Questionnaire-Somatic, Anxiety, and Depressive Symptoms; and Visual Analog Scale. Serum pro-inflammatory molecules were measured to evaluate the immunological status. The pain treatment significantly affected subjective sleep variables, psychiatric variables, clinical variables, and IL-6 levels. The subjective sleep parameters, clinical and psychiatric variables, and IL-6 levels were improved with pain treatment in fibromyalgia. The objective sleep variables, IL-1 and TNF-alpha levels were not significantly improved with the pain treatment, and they were not related to clinical presentation of patients with fibromyalgia. Subjective variability of sleep contributes to the clinical presentation, suggesting that the objective structure is trait-specific with IL-1 and TNF-alpha.

The aim of this study was to determine the quality of life (QoL) at the third month after stroke and to identify the factors related with and determinants of QoL in geriatric stroke patients. Eighty of 122 patients who were assessed within the first week after stroke were reevaluated at the third month. Patients were divided into two groups as those of ≥65 years old (geriatric group) and those of <65 years old (non-geriatric group). The stroke severity, functional status, and ambulation level were assessed by the Canadian neurological scale (CNS), the functional independence measure (FIM), and the functional ambulation classification scale (FACS) within the first week of stroke, respectively. Depression and QoL levels were also determined at the third month using the Zung self-rating depression scale (ZDS) and both the Short Form-36 (SF-36) survey and the stroke-specific quality of life (SSQoL) scale, respectively. The QoL of 80 patients according to the SF-36 were lower than those of general population. No significant difference was found in stroke severity, functional status at baseline and third month, depression and QoL between geriatric and non-geriatric patients (p>0.05). The most influenced subscale of QoL was work/productivity in geriatric patients, and the main determinant of QoL was the functional status during the assessment. Stroke patients had an impaired QoL, and geriatric patients did not demonstrate a difference in terms of QoL compared to non-geriatric patients. The fact that the main determinant of QoL was functional status has been suggested that improving of physical function may be helpful to provide a better QoL for stroke patients.
