BACKGROUND: Obstructive sleep apnea (OSA) has been linked to vestibular dysfunction, but no prior studies have investigated the relationship between Persistent Postural Perceptual Dizziness (PPPD), a common cause of chronic dizziness, and OSA. OBJECTIVE AND METHODS: We determined the frequency of OSA in an uncontrolled group of PPPD patients from a tertiary dizziness clinic based on polysomnogram (PSG). We then assessed the sensitivity and specificity of common OSA questionnaires in this population. RESULTS: Twenty-five patients with PPPD underwent PSG (mean age 47, 60% female, mean BMI 29.5). A majority, or 56%, of patients were diagnosed with OSA, and in most, the OSA was severe. OSA patients were older (56 years versus 40 years, p = 0.0006) and had higher BMI (32 versus 26, p = 0.0078), but there was no clear gender bias (56% versus 64% female, p = 1.00). The mean sensitivity and specificity of the STOP BANG questionnaire for detecting OSA was 86% and 55%, respectively. Sensitivity and specificity of the Berlin Questionnaire was 79% and 45%, respectively. CONCLUSIONS: The prevalence of OSA was much higher in our small PPPD group than in the general population. Screening questionnaires appear to demonstrate good sensitivity to detect PPPD patients at risk of OSA in this small study. Future studies should confirm these findings and determine whether treatment of OSA improves symptoms in PPPD.

Abstract Background To evaluate the effect of arterial bicarbonate (HCO3−) concentration on the accuracy of STOP-Bang questionnaire (SBQ) screening for obstructive sleep apnea (OSA). Methods A total of 144 patients with suspected OSA were included. Polysomnograms (PSG) and blood gas analysis were performed, and the Epworth Sleepiness Scale (ESS), STOP-Bang questionnaire, and Berlin questionnaire were completed. The correlation between the arterial HCO3− concentration, apnea hypopnea index (AHI), and other related indicators was analyzed. The scoring results of the ESS, SBQ, and Berlin questionnaire were compared with the PSG results, and the sensitivity and specificity were calculated in the form of a four-cell table. The changes in the sensitivity and specificity of OSA screening after SBQ alone and combined with HCO3− concentration were compared, and ROC curves were drawn. Results Arterial HCO3− concentration was positively correlated with AHI (r = 0.537, P < 0.001). The ratio of HCO3− concentration ≥ 24.6 mmol/L in the non-OSA group was significantly lower than that in the OSA group (25.0% VS 80.8%, P < 0.001). The sensitivity of the SBQ was higher than that of the ESS (97.5% VS 81.7%, P < 0.001) and the Berlin questionnaire (97.5% VS 79.2%, P < 0.001). There was no statistical significance in the specificity of the three scales (25%, 37.5%, 37.5%). A combined SBQ score ≥ 3 and HCO3− concentration ≥ 24.6 mmol/L showed increased specificity and decreased sensitivity compared with an SBQ score ≥ 3 alone, with a corresponding AUC of 0.771 (P < 0.01) and 0.613 (P > 0.05), respectively. Conclusion The sensitivity of the SBQ was better than that of the Berlin questionnaire and ESS. After combining arterial blood HCO3− concentration, the SBQ questionnaire increased the specificity of OSA prediction and decreased the sensitivity, which improved the accuracy of screening.

Background: Obstructive sleep apnea (OSA) is frequent in acute stroke patients and is associated with increased mortality and poor functional outcome. Polysomnography (PSG) is the gold standard diagnostic method for OSA, but it is impracticable as a routine for all acute stroke patients. We evaluated how OSA screening tools such as the Berlin Questionnaire (BQ) and the Epworth Sleepiness Scale (ESS) would perform when administered to relatives of stroke patients in the acute setting, and compared these individual tools against a combined screening score (SOS score). Methods: Ischemic stroke patients were submitted to a full PSG at the first night after symptoms onset. OSA severity was measured by apnea-hypopnea index (AHI). BQ and ESS were administered to relatives of stroke patients before the PSG. We combined elements of the BQ and ESS to create a new screening tool for OSA named Sleep Obstructive apnea score optimized for Stroke (SOS score). Results: Thirty-nine consecutives ischemic stroke patients were enrolled in our study. The mean age was 62.3 ±12.2 years. Age was significantly different between those with and without OSA (p=0.02). The mean body mass index and neck circumference were 26.7 ± 4.7 and 38.9 ± 4.0cm, respectively. OSA (AHI ≥ 10) was present in 76.9%. The area under the curve for SOS score (AUC:0.812; p=0.005) was superior to BQ (AUC:0.567; p=0.549) and also to ESS (AUC:0.646; p=0.119 vs. AUC:0.686; p=0.048) for severe OSA (IAH ≥ 30). The threshold of SOS ≤ 10 (present in 20.5% of patients) showed high sensitivity (90%) and negative predictive value (96.2%) for OSA; SOS ≥20 (17.9% of patients) showed high specificity (100%) and positive predictive value (92.5%) for severe OSA. Using SOS as a screening approach would decrease by around 40% the demand for PSG during the acute stroke setting. Conclusions: The SOS score when administered to relatives of stroke patients appears to be an appropriate tool to screen acute stroke patients for OSA, while decreasing the need for a formal sleep study during the acute stroke setting. The new derived SOS score is superior to BQ and ESS for identifying patients with OSA and Severe OSA during the acute phase of stroke.

Abstract Objectives The purpose of this pilot study was to determine whether compliance to auto-adjusting positive airway pressure (APAP) improves with the addition of a mandibular advancement device (MAD). Secondary outcome measures included were APAP pressure, subjective daytime sleepiness, apnea–hypopnea index (AHI), and mask leaks. Setting and Sample Population Participants included were diagnosed with moderate-to-severe obstructive sleep apnea (OSA) and became noncompliant to prescribed APAP. Thirteen participants with a mean age of 61.6 years were recruited for this study. Materials and Methods All participants were given a MAD to use with their APAP. Parameters measured included APAP pressure, AHI, mask leak reported via ResMed AirViewTM software, and self-reported daytime sleepiness (Epworth Sleepiness Scale [ESS]). A paired two-sample for mean t-test was performed to determine significance. Results The mean difference of pre- and postintervention APAP compliance was 23.1%, which was statistically significant (p = 0.015). The mean APAP air pressures were unchanged. The difference between pre- and postintervention mean ESS scores was 1.4 and was statistically significant (p = 0.027). The mean difference between pre- and postintervention AHI values and mask leak showed no significant difference. Conclusion This study showed that combination of APAP-MAD therapy, for patients with moderate-to-severe OSA who were noncompliant to APAP use, significantly increased compliance with APAP therapy, and significantly decreased the daytime sleepiness of participants.

The purpose of this integrative review was to synthesize evidence concerning the relationship between comorbid obstructive sleep apnea and insomnia (OSA+I), and depressive symptoms. OSA and insomnia are common sleep disorders, recently comorbid OSA+I has been recognized as prevalent in adults. Although each sleep disorder increases the risk and severity of depressive symptoms, the effect of comorbid OSA+I on depressive symptoms remains unclear. A systematic search of PubMed, CINAHL, and PsycINFO identified 15 data-based studies. All the studies were observational with either a cross-sectional (n = 14) or a case-control design (n = 1). Study quality was assessed. Most of the studies (n = 14) indicated that comorbid OSA+I had an additive role on depressive symptoms. Insomnia appeared to have a more important role than OSA in increasing the severity of depressive symptoms in persons with comorbid OSA+I.
