Daytime Sleepiness in Patients Diagnosed with Sarcoidosis Compared with the General Population.

Background: The aim of this study was to analyze daytime sleepiness in a sample of patients diagnosed with sarcoidosis.

Methods: A sample of 1197 German sarcoidosis patients was examined with the Epworth Sleepiness Scale (ESS), the Fatigue Assessment Scale, the Hospital Anxiety and Depression Scale, the Pittsburgh Sleep Quality Index, and the Short-Form Health Survey (SF-8). The patients' ESS mean scores were compared with those obtained from a large general population sample.

Fatigue and Excessive Daytime Sleepiness in Sarcoidosis: Prevalence, Predictors, and Relationships between the Two Symptoms.

Background: Fatigue is common among patients with sarcoidosis. The etiology of this problem is unknown and multifactorial. Fatigue can be confounded with excessive daytime sleepiness (EDS).

Subjective sleep quality in sarcoidosis.

Background: Poor sleep is common among patients with medical disorders. Sleep disturbances can be a cause of fatigue and poor quality of life for patients suffering from sarcoidosis. Studies on subjective sleep quality or prevalence of insomnia have not been reported so far.

Objective markers for sleep propensity: comparison between the Multiple Sleep Latency Test and the Vigilance Algorithm Leipzig.

The regulation of wakefulness is important for high-order organisms. Its dysregulation is involved in the pathomechanism of several psychiatric disorders. Thus, a tool for its objective but little time-consuming assessment would be of importance.

Factors associated with fatigue in sarcoidosis.

Background: Fatigue is a frequent symptom of patients with sarcoidosis. The origin of fatigue associated with sarcoidosis is unclear. The aim of this study was to assess the impact of affected organs, medication, and comorbidity on fatigue related to sarcoidosis.

Circulating anandamide and blood pressure in patients with obstructive sleep apnea.

Objective: Obstructive sleep apnea chronically increases blood pressure through sympathetic nervous system activation. In animals, hypertension and sympathetic activity are restrained by cannabinoid receptor activation. Therefore, we hypothesized that increased blood pressure in patients with obstructive sleep apnea is associated with increased circulating endocannabinoid concentrations.

Fatigue in patients with sarcoidosis, compared with the general population.

Objective: Fatigue is a significant symptom in sarcoidosis patients. The causes for this symptom are unclear. The aims of this study were to analyze age and gender differences in fatigue, compared with the general population, and to test the psychometric properties of two questionnaires measuring fatigue in sarcoidosis.
