Objective To determine the independent role of nasal congestion in positive airway pressure (PAP) therapy compliance and factors associated with an unfavorable shift of PAP compliance. Study Design Prospective cohort study. Setting Tertiary care center. Methods This follow-up study comprised 174 patients with newly diagnosed obstructive sleep apnea (OSA) who accepted PAP therapy from January 2017 to June 2019. Information was collected on basic demographics, comorbidities, sleep-related symptoms, nasal symptoms, and upper airway assessment. PAP adherence data were collected at the end of the first week and the third month. Results After 3 months of follow-up, 147 participants were included for final data analysis. The proportion of nasal congestion (29.2% vs 52.0%, P = .005) and its severity (mean rank, 58.5 vs 75.1; P = .007) were significantly higher in the noncompliance group as compared with the compliance group. After adjustment for basic demographics, comorbidities, sleep-related symptoms or sleep study parameters, and Friedman clinical staging, multinomial logistic regression models showed that nasal congestion (all odds ratios >2.0, P < .05) was independently associated with a higher odds of PAP noncompliance. Patients with an unfavorable shift of PAP compliance were younger (mean ± SD, 47.5 ± 10.6 vs 53.1 ± 12.6 years; P = .021) and had a lower body mass index (27.2 ± 3.7 vs 29.3 ± 5.0, P = .027) than those who consistently complied. OSA severity was associated with PAP compliance, initially and in the long term. Conclusion Nasal congestion is an independent predictor of PAP noncompliance. Younger patients with lower BMI were more likely to have an unfavorable shift of PAP compliance. Initial and long-term adherence to PAP therapy was affected by OSA severity.

OBJECTIVE: Outcome data on the surgical treatment of obstructive sleep apnea are, in general, based on short-term follow-up (<6–9 months). This examination was undertaken to assess long-term results. METHODS: Forty patients who underwent soft tissue and skeletal surgery were the subjects of this review. Methods of evaluation included polysomnographic variables (respiratory disturbance index [RDI], low oxyhemoglobin desaturation [LSATT]), body mass index, quality-of-life assessments, roentgenographic analysis, and complications. Statistical analysis used the SAS 6.12 system. RESULTS: Thirty-six of 40 patients (90%) showed long-term clinical success. The mean preoperative RDI, nasal continuous positive airway pressure RDI, and long-term RDI were 71.2 ± 27.0, 7.6 ± 5.2 and 7.6 ± 5.1, respectively. The mean preoperative LSAT, nasal continuous positive airway pressure LSAT, and long-term LSAT were 67.5% ± 14.8%, 87.1% ± 3.2%, and 86.3% ± 3.9%, respectively. The mean follow-up was 50.7 ± 31.9 months. The patients showed a statistically significant long-term weight gain ( P = 0.0002) compared with their 6-month postoperative level (body mass index 31.4 ± 6.7 vs 32.2 ± 6.3). There was a positive correlation with the amount of skeletal advancement and clinical outcome. CONCLUSION: Comprehensive evaluation and surgical treatment can result in successful long-term clinical outcome.

Background: We sought to investigate whether long-term continuous positive airway pressure (CPAP) treatment in patients with obstructive sleep apnea (OSA) and resistant hypertension (RHTN) could attenuate the cardiovascular disease risk by lowering their body-mass index (BMI). Methods: This was a long-term observational study of RHTN patients diagnosed with OSA. Patients were evaluated with polysomnography initially and after a mean follow-up period of four years. The patients were divided into two groups based on their compliance to CPAP therapy. Results: 33 patients (aged 54.67 ± 7.5, 18 men, 54.5%) were included in the study, of which 12 were compliant to CPAP therapy. A significant reduction in BMI at follow-up was noted in patients compliant to CPAP therapy (1.4 ± 3.5 vs. −1.6 ± 2.5, p = 0.006). We also noted a large effect size reduction in abdominal circumference at follow-up in the CPAP group. At follow-up evaluation, the mean heart rate (b/min) was lower in the CPAP group (58.6 ± 9.5 vs. 67.8 ± 7.8), while arrhythmia prevalence increased between initial (28.6%) and follow-up (42.9%) evaluation with an intermediate effect size in non-compliant patients. Conclusions: In our cohort of OSA patients with RHTN, long-term adherence to CPAP therapy was associated with weight loss and improvement in cardiac rhythm outcomes.

AbstractObstructive sleep apnea (OSA) is a common cause of hypertension. Previous studies have demonstrated beneficial short-term effects of continuous positive airway pressure (CPAP) therapy on blood pressure. However, long-term antihypertensive effects of CPAP have not been properly verified. This study examined the longitudinal effect of CPAP therapy adherence on blood pressure among OSA patients. All patients diagnosed with OSA and undergoing subsequent CPAP therapy at a Kanagawa-area sleep clinic were clinically followed for 24 months to examine CPAP adherence, as well as longitudinal changes in blood pressure and body weight because it may become a confound factor for changes in blood pressure. The hours of CPAP usage were collected over the course of 30 nights prior to each follow-up visit (1st, 3rd, 6th, 12th, and 24th month). The relationship between CPAP adherence and blood pressure was analyzed using mixed-effect logistic regression models. A total of 918 OSA patients were enrolled in the study. We found a significant reduction in diastolic blood pressure among patients with good CPAP adherence during the 24-month follow-up period (β = − 0.13, p = 0.03), when compared to the group with poor CPAP adherence. No significant association was found between CPAP adherence and weight loss (β = − 0.02, p = 0.59). Long-term, good CPAP therapy adherence was associated with lower diastolic blood pressure without significant weight loss.
