Sleep Hypoxemia and Urinary Free Cortisol in Patients with Obstructive Sleep Apnea
Author(s): Suelem Izumi, Fernando Flexa Ribeiro-Filho, Glaucia Carneiro, Sonia M Togeiro, Sergio Tufik and Maria Teresa Zanella
Objective: This study evaluated the influence of obstructive sleep apnea (OSA) on hypothalamic–pituitary–adrenal (HPA) axis aiming to identify the polysomnographic data associated with cortisol abnormalities.
Methods: Forty-one men referred for suspected OSA underwent polysomnography and were classified according to the apneahypopnea index (AHI) into control group (n=16) and OSA group (n=25). The assessment of the HPA axis function included low-dose (0.25 mg) dexamethasone suppression test, the circadian rhythm of salivary cortisol secretion and the measurement of urinary free cortisol (UFC) excretion in a 24-hour urine collection.
Results: No differences were found be... view more»
