Circadian Variations of Prostaglandin in Sleep Apnea
Summary
The purpose of this study is to evaluate the associations of circadian variations, sleep architecture, hypertension and prostanoids in the patients with sleep apnea. In addition, the patients introduced to continuous positive airway pressure(CPAP) treatment, the effects of CPAP are also evaluated.
Description
Obstructive sleep apnea (OSA) is characterized by repetitive episodes of upper airway obstruction during sleep that provoke frequents arousals, sleep fragmentation, oxygen desaturation, and excessive daytime sleepiness. OSA may contribute to the development of systemic hypertension, cardiovascular disease. Many studies has reported a crucial role for the prostaglandin D system in sleep regulation. In addition, it has been described urinary or blood levels of prostaglandins was higher in the patients with hypertension, diabetes mellitus, and these values were associated with the severity of coronary artery disease. However, the relation between alterations of prostaglandin D system and sleep architecture, sleepiness, and clinical outcomes such as hypertension, arteriosclerosis in the patients with OSA are not known. Additionally, after CPAP treatment, we will investigate the association between change of prostaglandin system and sleep architecture, sleepiness, clinical outcomes.

Medical and Biotech [MESH] Definitions
Sleep Apnea, Central
A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)
Sleep Apnea Syndromes
Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.
Sleep Disorders, Intrinsic
Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
Strychnine
An alkaloid found in the seeds of STRYCHNOS NUX-VOMICA. It is a competitive antagonist at glycine receptors and thus a convulsant. It has been used as an analeptic, in the treatment of nonketotic hyperglycinemia and sleep apnea, and as a rat poison.
Sleep Apnea, Obstructive
A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)
