Morning Headache

Morning headache is accepted as part of clinical findings of obstructive sleep apnoea syndrome (OSAS). The prevalence of morning headache is at variable levels from 18% to 74% in patients with OSAS. However, there is controversy over the association of morning headache and OSAS. We studied morning headache prevalance and characteristics in 101 controls with apnoea-hypnoea index (AHI) < 5 and 462 OSAS patients with AHI ≥ 5. Morning headache was reported by only nine (8.9%) subjects in a control group compared with 156 (33.6%) of OSAS patients ( P < 0.01). Morning headache prevalance was significantly higher in severe and moderate OSAS groups. AHI was significantly higher in OSAS patients with morning headache compared with patients without morning headaches. Oxygen saturation nadir during rapid eye movement and non-rapid eye movement sleep as well as mean oxygen saturation value during total sleep time were also found to be significantly lower in morning headache group. However, none of the sleep parameters was found to be determinants of morning headache. Morning headache was more frequently reported by patients of female gender and with primary headache history. Morning headache was totally resolved in 90% of patients treated with nasal continuous positive airway pressure. The history of OSAS should be considered in the differential diagnosis of morning headache.

Background: Rapid eye movement (REM) obstructive sleep apnea (OSA) represents 13 to 35% of all OSA cases and is more common in women. Continuous positive airway pressure (CPAP) is the gold standard for treatment of all forms of OSA but we do not know if patients with REM OSA have different pressure requirements than those with non-stage dependent OSA. Methods: This was a retrospective case control study. We first identified individuals with REM OSA and then tried to identify apnea hypopnea index (AHI), gender, and body mass index (BMI) matching controls that had non-stage specific OSA. Individuals were considered to have REM OSA if the REM AHI was greater than 5 events/hour, and the ratio of REM AHI / non-rapid eye movement (NREM) AHI was greater than 2. Demographic variables and the recommended CPAP pressure were analyzed using paired Student’s T-Tests. Results: Our study included a total of 16 individuals with REM OSA and equal number of AHI, gender, and BMI matching controls. Both groups had similar demographic and polysomnographic characteristics.  Individuals with REM OSA required similar CPAP pressures as controls (7.5 cm H 2O vs 7.4 cm H 2O p=0.78). Conclusion: Individuals with REM might require similar CPAP pressures as their AHI, gender, and BMI matching controls.

Predictors Of Adherence

Objective Rapid eye movement (REM)-related obstructive sleep apnea (OSA) is characterized by respiratory events such as apnea and hypopnea predominately or exclusively during REM sleep. Several studies have revealed clinical predictors of adherence to the use of continuous positive airway pressure (CPAP). However, the effect of REM-related OSA on adherence to CPAP use remains unclear. Therefore, we investigated the effects of REM-related OSA on adherence to CPAP use 6 months after treatment initiation. Methods We enrolled 161 patients in this study and divided them into 3 groups: the good adherence, poor adherence, and dropout groups. We compared polysomnographic data and clinical findings, including those regarding morbidity of REM-related OSA, among the three groups to identify predictors of adherence to CPAP use. Results None of the 43 patients in the good adherence group had REM-related OSA. Multivariate logistic regression analysis of the good adherence and dropout groups indicated that REM-related OSA was the only factor associated with adherence to CPAP use (odds ratio, 41.984; 95% confidence interval, 2.257–781.007). Conclusions REM-related OSA is a reliable risk factor for dropout from CPAP therapy.

The Impact

The aim of the present study was to evaluate the impact of obstructive sleep apnoea syndrome (OSAS) and the effects of nasal continuous positive airway pressure (CPAP) on circulating ischaemia-modified albumin (IMA) concentrations. The study included 97 newly diagnosed OSAS patients and 30 nonapnoeic controls. Blood samples were obtained in the morning after polysomnography. After 3 months of CPAP treatment, 31 patients with moderate-severe OSAS were reassessed for serum IMA concentrations. Significantly higher serum IMA concentrations were measured in the OSAS group than in the control group [0.518±0.091absorbance units (ABSU),0.415±0.068ABSU,P<0.001]. Serum IMA concentrations correlated significantly with the apnoea-hypopnoea index, mean SaO2, desaturation index, and C-reactive protein concentrations. Multiple logistic regression analyses showed that OSAS increased the serum IMA concentration independent of age, sex, body mass index, smoking habit, and cardiovascular disease. After 3 months of treatment with CPAP, OSAS patients had significantly lower serum IMA concentrations (0.555±0.062ABSU to0.431±0.063ABSU,P<0.001). The results showed that OSAS is associated with elevated concentrations of IMA, which can be reversed by effective CPAP treatment.

RationaleThe impact of treatment for obstructive sleep apnoea (OSA) on reduction of cardiovascular risk is unclear. This study aimed to examine the effect of continuous positive airway pressure (CPAP) on ambulatory blood pressure (BP) and subclinical myocardial injury in subjects with OSA and hypertension.MethodsSubjects with hypertension requiring at least three anti-hypertensive medications and moderate-severe OSA were enrolled. Eligible subjects were randomized (1:1) to receive either CPAP treatment or control (no CPAP) for eight weeks. Changes in ambulatory BP and serum biomarkers were compared. Stratified analysis according to circadian BP pattern was performed.Main resultsNinety two subjects (75% men; age, 51±8 years; apnoea-hypopnoea index 40±8 events·h−1, taking average of 3.4 anti-hypertensive drugs [range 3–6]) were randomised. The group on CPAP treatment, compared to the control group, demonstrated significant reduction in 24-h systolic BP (−4.4 mmHg, 95% CI −8.7 to −0.1, p=0.046), 24-h diastolic BP (−2.9 mmHg, 95% CI −5.5 to −0.2, p=0.032), daytime systolic BP (−5.4 mmHg, −9.7 to −1.0, p=0.016) and daytime diastolic BP (−3.4 mmHg, 95% CI −6.1 to −0.8, p=0.012). CPAP treatment was associated with significant BP lowering only in non-dippers, but not in dippers. Serum troponin I (mean difference −1.74 pg·mL−1, 95% CI −2.97 to −0.5, p=0.006) and brain natriuretic peptide (−9.1 pg·mL−1, 95% CI −17.6 to −0.6, p=0.036) were significantly reduced in CPAP compared to control group.ConclusionIn a cohort with OSA and multiple cardiovascular risk factors including difficult-to-control hypertension, short-term CPAP treatment improved ambulatory BP and alleviated subclinical myocardial injury and strain.

Disordered Breathing

Introduction To date, continuous positive airway pressure (CPAP) remains the cornerstone of obstructive sleep apnoea treatment. CPAP data describing residual sleep-disordered breathing events (ie, the CPAP-measured apnoea–hypopnoea indices (AHI-CPAPflow)) is difficult to interpret because it is an entirely different metric than the polysomnography (PSG) measured AHI gold standard (AHI-PSGgold). Moreover, manufacturer definitions for apnoea and hypopnoea are not only different from those recommended for PSG scoring, but also different between manufacturers. In the context of CPAP initiation and widespread telemedicine at home to facilitate sleep apnoea care, there is a need for concrete evidence that AHI-CPAPflow can be used as a surrogate for AHI-PSGgold. Methods and analysis No published systematic review and meta-analysis (SRMA) has compared the accuracy of AHI-CPAPflow against AHI-PSGgold and the primary objective of this study is therefore to do so using published data. The secondary objectives are to similarly evaluate other sleep disordered breathing indices and to perform subgroup analyses focusing on the inclusion/exclusion of central apnoea patients, body mass index levels, CPAP device brands, pressure titration modes, use of a predetermined and fixed pressure level or not, and the impact of a 4% PSG desaturation criteria versus 3% PSG on accuracy. The Preferred Reporting Items for SRMA protocols statement guided study design. Randomised controlled trials and observational studies of adult patients (≥18 years old) treated by a CPAP device will be included. The CPAP intervention and PSG comparator must be performed synchronously. PSGs must be scored manually and follow the American Academy of Sleep Medicine guidelines (2007 AASM criteria or more recent). To assess the risk of bias in each study, the Quality Assessment of Diagnostic Accuracy Studies 2 tool will be used. Ethics and dissemination This protocol received ethics committee approval on 16 July 2020 (IRB_MTP_2020_07_2020000404) and results will be disseminated via peer-reviewed publications.
