- The effect of positive airway pressure treatment on weight and markers of central obesity in patients with obstructive sleep apnea remains unclear. We studied the change in body weight and anthropometric measures following positive airway pressure treatment in a large clinical cohort. Patients with obstructive sleep apnea with positive airway pressure treatment from the European Sleep Apnea Database registry (n=1,415, 77% male, age 54±11 [mean±SD] years, body mass index 31.7±6.4kg/m2 , apnea-hypopnea index 37±24n per hr, Epworth Sleepiness Scale 10.2±5.0) were selected. Changes in body mass index and neck/waist/hip circumferences at baseline and at follow-up visit were analysed. Overall, body mass index (0.0 [95% confidence interval, -0.1 to 0.2]kg/m2 ) and neck circumference (0.0 (95% confidence interval, -0.1 to 0.1]cm) were unchanged after positive airway pressure treatment compared with baseline (follow-up duration 1.1±1.0years and compliance 5.2±2.1hr per day). However, in non-obese (body mass index <30kg/m2 ) patients, positive airway pressure treatment was associated with an increased body mass index and waist circumference (0.4 [0.3-0.5]kg/m2 and 0.8 [0.4-1.2]cm, respectively, all p<0.05), and weight gain was significantly associated with higher positive airway pressure compliance and longer positive airway pressure treatment duration. In the obese subgroup, body mass index was reduced after positive airway pressure treatment (-0.3 [-0.5 to -0.1]kg/m2 , p<0.05) mainly in patients with a strong reduction in Epworth Sleepiness Scale. In conclusion, positive airway pressure therapy was not found to systematically change body mass index in the European Sleep Apnea Database cohort, but the response was heterogeneous. Our findings suggest that weight gain may be restricted to an obstructive sleep apnea phenotype without established obesity. Lifestyle intervention needs to be considered in both lean and obese patients with obstructive sleep apnea receiving positive airway pressure treatment.

Use of the Clinical Global Impression scale in sleep apnea patients-Results from the ESADA database.
- 2019

Journal article (peer-reviewed)abstract
- The Clinical Global Impression scale (CGI) reflects the clinician's assessment of the disease impact on patient's global functioning. We assessed predictors of CGI scale rating in patients with obstructive sleep apnea (OSA).Consecutive patients with suspected OSA (n=7581) were identified in the European Sleep Apnea Database (ESADA). Anthropometrics, comorbidities, apnea severity obtained by polygraphy or polysomnography, and daytime sleepiness [Epworth Sleepiness Scale (ESS)] were assessed. The CGI 7-point scale was completed at the end of the diagnostic process (CGI-severity, ie, CGI-S) and, in a subpopulation, at treatment follow-up (CGI-Improvement).CGI-S was rated mild to moderate in 44% of patients. CGI rating at any given apnea intensity was worse in women than in men (p<0.01). Patients undergoing polygraphy (n=5075) were more frequently rated as severely ill compared to those studied with polysomnography (19.0% vs 13.0%, p<0.001). In patients aged ≤65 years, CGI scoring was generally better than in the elderly despite a similar degree of OSA (eg, 'normal, not ill' 24.2% vs 15.3%, p<0.01, respectively). Independent predictors of CGI rating included age, BMI, AHI, ESS, cardio-metabolic comorbidities, and diagnosis based on polygraphy. CGI-improvement rating (Beta=-0.406, p<0.01) was superior to sleep apnea severity or ESS-score (Beta=0.052 and-0.021, p=0.154 and 0.538 respectively) at baseline for prediction of good CPAP compliance at follow-up.CGI rating is confounded by gender, age class and the type of sleep diagnostic method. As OSA phenotypes differ, CGI may contribute as a clinical tool to reflect the significance of clinical disease.

Current and novel treatment options for obstructive sleep apnoea
- 2022

In: ERJ Open Research. - : European Respiratory Society. - 2312-0541. ; 8:2

Research review (peer-reviewed)abstract
- Obstructive sleep apnoea is a challenging medical problem due to its prevalence, its impact on quality of life and performance in school and professionally, the implications for risk of accidents, and comorbidities and mortality. Current research has carved out a broad spectrum of clinical phenotypes and defined major pathophysiological components. These findings point to the concept of personalised therapy, oriented on both the distinct clinical presentation and the most relevant pathophysiology in the individual patient. This leads to questions of whether sufficient therapeutic options other than positive airway pressure (PAP) alone are available, for which patients they may be useful, if there are specific indications for single or combined treatment, and whether there is solid scientific evidence for recommendations. This review describes our knowledge on PAP and non-PAP therapies to address upper airway collapsibility, muscle responsiveness, arousability and respiratory drive. The spectrum is broad and heterogeneous, including technical and pharmaceutical options already in clinical use or at an advanced experimental stage. Although there is an obvious need for more research on single or combined therapies, the available data demonstrate the variety of effective options, which should replace the unidirectional focus on PAP therapy.

European Respiratory Society guideline on non-CPAP therapies for obstructive sleep apnoea
- 2021

In: European Respiratory Review. - : ERS Publications. - 0905-9180 .- 1600-0617. ; 30:162

Journal article (peer-reviewed)abstract
- Treatment of obstructive sleep apnoea (OSA) in adults is evolving, as new therapies have been explored and introduced in clinical practice, while other approaches have been refined or reconsidered. In this European Respiratory Society (ERS) guideline on non-continuous positive airway pressure (CPAP) therapies for OSA, we present recommendations determined by a systematic review of the literature. It is an update of the 2011 ERS statement on non-CPAP therapies, advanced into a clinical guideline. A multidisciplinary group of experts, including pulmonary, surgical, dentistry and ear-nose-throat specialists, methodologists and patient representatives considered the most relevant clinical questions (for both clinicians and patients) relating to the management of OSA. Eight key clinical questions were generated and a systematic review was conducted to identify published randomised clinical trials that answered these questions. We used the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach to assess the quality of the evidence and the strength of recommendations. The resulting guideline addresses gastric bypass surgery, custom-made dual-block mandibular advancement devices, hypoglossal nerve stimulation, myofunctional therapy, maxillo-mandibular osteotomy, carbonic anhydrase inhibitors and positional therapy. These recommendations can be used to benchmark quality of care for people with OSA across Europe and to improve outcomes.
