Polysomnographic data, sleep quality, sleepiness and co-morbidities in patients with REM-related obstructive sleep apnea

Purpose. To determine differences in polysomnographic values, sleep quality, sleep- related symptoms and co-morbidities between the patients suffering from REM-related OSA and controls suffering from OSA equally distributed in REM and non-REM. Methods. From the Split Sleep Medicine Center data pool of 500 patients with polysomnography (PSG) recordings, 38 patients with REM-related OSA were recruited, and 38 case control patients with non-REM OSA were identified when adjusted for age, gender, BMI and AHI. REM- related OSA was defined as follows: AHI≥5, AHI(REM)/AHI(NREM)≥2, and REM>30 min. Whole-night PSG studies were performed on all patients using the Alice 5LE, and they responded to STOP, STOP- BANG, Berlin questionnaire, Epworth Sleepiness Scale, Stanford Sleepiness Scale and Pittsburgh sleep quality index. Results. Patients with REM- related OSA were no different compared with controls on PSG data except they had greater snoring time (136.0±130.8 vs. 68.0±57.9 minutes, p<0.014). Arterial hypertension was more frequent in REM-related OSA group in comparison to control (18/35 vs. 10/38, p=0.027), and there was a tendency that they were less sleepy during the day in comparison to control on ESS score (6.4±5.3 vs. 7.8±4.8, p=0.224), and SSS score (2.6±1.4 vs. 3.1±1.3, p=0.099). Conclusion. There were no significant differences between patients with REM- related OSA and control patients in objective data from sleep studies, but they had prolonged period of snoring. Subjective data indicated a tendency toward less pronounced sleepiness and more frequent coexistence of arterial hypertension in patients with REM- related OSA.
