Obstructive sleep apnea syndrome: association of serum melatonin, increased daytime sleepiness, and intermitting night hypoxemia

The relevance of studies related to the features of respiratory disorders during sleep is undeniable due to the steady growth of the worldwide prevalence of apnea syndrome, which leads to a decrease in quality of life, the risk of early cardiovascular diseases together with cerebrovascular, endocrine, and pulmonary disorders.The aim of this study was to determine the relationship between the morning serum melatonin, blood oxygen saturation (SрO2), and increased daytime sleepiness in patients with SOAS, as well as to assess changes in the production of endogenous melatonin after eliminating clinical manifestations of nocturnal hypoxemia, through a 3-month course of non-invasive continuous positive airway pressure (CPAP) therapy. The study enrolled 30 male patients who came to the Federal State Public Scientific Institution “Scientific Centre of Family Health and Human Reproduction Problems” because of snoring, sleep apnea, and increased daytime sleepiness.Methods. Polysomnography, questionnaire, HPLC-MS/MS analysis of serum melatonin levels, CPAP-therapy for the respiratory support at home for 3 months, monitoring of the sleep scores, serum melatonin, and daytime sleepiness after the treatment.Results. A comparative assessment of the sleep scores before and after the respiratory support for 3 months revealed a significant improvement in sleep structure, elimination of the apnea episodes, and restoration of blood SрO2 after the therapy. Analysis of the serum melatonin vales confirmed a statistically significant increase of melatonin level against baseline in patients with SOAS after the treatment. A correlation analysis showed a relationship between the melatonin level, daytime sleepiness, and blood SрO2.Conclusion. The results of this study and the data of other researchers demonstrate that the elimination of intermittent nocturnal hypoxia in patients with SOAS allows reducing the morning serum melatonin level, thereby reducing the daytime sleepiness and subsequently improving the quality of life.

Background and aims. Obstructive sleep apnea syndrome (OSA) affects the quality of life (QOL) due to the effects on the patient’s physical and mental function. QOL in sleep apnea may improve under continuous airway positive pressure (CPAP) therapy. The purpose of this study was to assess the OSA patients QOL before and after 3 months of CPAP therapy using Calgary Sleep Apnea Quality of Life Index (SAQLI).Methods. We conducted a study in 79 sleep apnea subjects diagnosed using cardiorespiratory portable monitoring, under CPAP therapy, monitored in our Sleep Laboratory from January 2011 to December 2014. This is a cross-sectional study, achieved through quantitative research (SAQLI questionnaire application) about the perception of quality of life in patients with sleep apnea in the moment of diagnosis and 3 months after CPAP therapy. Results. Of the 79 subjects, 59 (74.7%) were men and 20 (26.3%) women; mean age was 54.13 years (SD±10.87), the mean apnea-hypopnea index (AHI) was 52.46±20.83 events/h. In all 4 domains of SAQLI: daily functioning with mean pretreatment score 4.13±0.58 versus mean post treatment score 5.43±0.52; social interactions with mean pretreatment score 3.68±0.55 versus post treatment mean score 5.36±0.57; emotional functioning with mean pretreatment score 3.83±0.53 versus mean post treatment mean 5.38±0.56 and symptoms with mean pretreatment score 0.81±0.12 versus mean post treatment score 1.15±0.14, quality of life was improved after 3 months of therapy, with significantly statistical correlation (p=0.00). Also, an improvement was seen in mean total score of SAQLI after therapy as compared to baseline 3.11±0.32 versus 4.24±0.39 (p<0.01). Conclusion. The quality of life in sleep apnea was better after CPAP therapy than from baseline, according Calgary Sleep Apnea Quality of Life Index. The SAQLI is a useful toll to evaluate quality of life in sleep apnea, especially to highlight the benefits of CPAP therapy, even with short time monitoring.

Objective. To determine the dynamics of the clinical and psychological characteristics on the background of 1 month of CPAP therapy in patients with obstructive sleep apnea syndrome (OSA) and arterial hypertension (AH), both adherent and non-adherent to the treatment. Methods. The study included 180 patients with OSA and AH. Upon enrollment, anthropometric data, the results of polysomnography and cardiorespiratory studies, Beck depression scale, Spielberger personal and situational anxiety scale, Epworth daytime sleepiness scale, Pittsburgh sleep quality questionnaire and Quality of Life (WHO QOL-100) questionnaire were analysed. Out of 40 patients undergoing CPAP therapy, 30 patients were adherent to the treatment within a month. The adherence criterion was considered to be the usage of the CPAP device more than 4 hours per night, more than 5 days a week. In this article, the dynamics of the questionnaire scales is given only for those who were adherent to CPAP therapy. Results. Patients with OSA and AH adherent to CPAP therapy showed a statistically significant reduction in daytime sleepiness and depression, as well as improved quality of sleep and quality of life in the physical domain within 1 month of using CPAP therapy. Conclusion. Even short-term use of CPAP therapy in patients with OSA and AH leads to a reduction in daytime sleepiness and depression, improved quality of sleep and quality of life in the physical domain.

ABSTRACT Objective: To investigate whether the presence of obstructive sleep apnea syndrome (OSAS) alters the perception of respiratory symptoms and quality of life in COPD patients, by using specific questionnaires, as well as to determine whether scales for assessing daytime sleepiness and for screening for OSAS can be used in the triad of OSAS, COPD, and obesity. Methods: We included 66 patients diagnosed with mild-to-moderate or severe COPD and presenting with a body mass index > 27 kg/m2. After polysomnography, patients completed the Epworth sleepiness scale (ESS), the Berlin questionnaire (BQ), the modified Medical Research Council (mMRC) scale, the Baseline Dyspnea Index (BDI), and the Saint George’s Respiratory Questionnaire (SGRQ). Results: Patients were first divided into two groups: COPD + OSAS (n = 46); and COPD-only (n = 20). The COPD + OSAS group was subdivided into a COPD + mild-to-moderate OSAS group (n = 32) and a COPD + severe OSAS group (n = 14), all of which were compared with the COPD-only group. There was a significant difference in mean FEV1 (L) between the COPD + OSAS groups and the COPD-only group (p = 0.073). The presence of the triad did not lead to significantly higher ESS scores, and scores > 10 had a specificity of 0.58. The BQ did not identify high risk for OSAS in the presence of the triad (specificity of 0.31). There were no significant differences in domain or total scores of the SGRQ between the COPD + OSAS groups and the COPD-only group. Conclusions: The confounding factors present in the triad of OSAS, COPD, and obesity prevented the perception of increased daytime sleepiness and high risk for OSAS. We observed no worsening of dyspnea perception or quality of life.
