The reduction in blood pressure (BP) with continuous positive airway pressure (CPAP) is modest and highly variable. In this study, we identified the variables that predict BP response to CPAP.24-h ambulatory BP monitoring (ABPM), C-reactive protein (CRP), leptin, adiponectin and 24-h urinary catecholamine were measured before and after 6 months of CPAP in obstructive sleep apnoea (OSA) patients.Overall, 88 middle-aged, obese male patients with severe OSA (median apnoea–hypopnoea index 42 events·h−1) were included; 28.4% had hypertension. 62 patients finished the study, and 60 were analysed. The daytime diastolic BP (−2 mmHg) and norepinephrine (−109.5 nmol·day-1) were reduced after CPAP, but no changes in the 24-h BP, night-time BP, dopamine, epinephrine, CRP, leptin or adiponectin were detected. The nocturnal normotension was associated with an increased night-time-BP (+4 mmHg) after CPAP, whereas nocturnal hypertension was associated with a reduction of 24-h BP (−3 mmHg). A multivariate linear regression model showed differential night-time BP changes after CPAP. Specifically, low night-time heart rate (<68 bpm) and BP dipper profile were associated with increased night-time BP and new diagnosis of nocturnal hypertension.Our results suggest that nocturnal hypertension, circadian BP pattern and night-time heart rate could be clinical predictors of BP response to CPAP and support the usefulness of 24-h ABPM for OSA patients before treatment initiation. These results need to be confirmed in further studies.

Load Indices

Aim. To assess the specifics of 24-hour blood pressure monitoring (BPM) parameters and their association with body mass index (BMI) in patients with arterial hypertension (AH) and obstructive sleep apnoea (OSA) syndrome. Material and methods. The study included 120 AH patients with BMI under or over 25 kg/m2, who underwent 24-hour BMP and combined monitoring of electrocardiogram (ECG) and breathing. Results. AH patients with OSA syndrome demonstrated increased mean daytime and nighttime levels of systolic and diastolic BP (SBP, DBP) and a 1,5-fold increase in SBP and DBP pressure load indices. Patients with increased BMI had disturbed circadian BP profile, with reduced mean 24-hour difference, more pronounced for DBP (2,4-fold difference), and an increase in the “over-dipper” prevalence (from 13,3 % to 42,1 %). Conclusion. The combination of AH, OSA syndrome, and increased BMI substantially affected 24-hour BPM parameters. Increased BMI was associated with disturbed circadian BP profile and increased levels of mean 24-hour BP and nighttime BP

The Impact

OSA (obstructive sleep apnoea) stimulates sympathetic nervous activity and elevates resting HR (heart rate) and BP (blood pressure). In the present study in a cohort of 309 untreated OSA patients, the resting HR and BP during the daytime were correlated with AHI (apnoea/hypopnea index) and compared with patients with R389R (n=162), R389G (n=125) and G389G (n=22) genotypes of the β1-adrenoreceptor R389G polymorphism. We analysed the impact of the genotype on the decline of HR and BP in a subgroup of 148 patients (R389R, n=86; R389G, n=54; G389G, n=8) during a 6-month follow-up period under CPAP (continuous positive airway pressure) therapy during which cardiovascular medication remained unchanged. In untreated OSA patients, we found an independent relationship between AHI and resting HR (β=0.096, P<0.001), systolic BP (β=0.09, P=0.021) and diastolic BP (β=0.059, P=0.016). The resting HR/BP, however, did not differ among carriers with the R389R, R389G and G389G genotypes. CPAP therapy significantly reduced HR [−2.5 (−1.1 to −4.0) beats/min; values are mean difference (95% confidence intervals)] and diastolic BP [−3.2 (−1.5 to −5.0) mmHg]. The decline in HR was more significantly pronounced in the R389R group compared with the Gly389 carriers [−4.1 (−2.3 to −5.9) beats/min (P<0.001) compared with −0.2 (2.1 to −2.6) beats/min (P=0.854) respectively; Student's t test between groups, P=0.008]. Diastolic BP was decreased significantly (P<0.001) only in Gly389 carriers (R389G or G389G) compared with R389R carriers [−5.0 (−2.3 to −7.6) mmHg compared with −2.0 (0.4 to −4.3) mmHg respectively]. ANOVA revealed a significant difference (P=0.023) in HR reduction between the three genotypes [−4.1 (±8.4) beats/min for R389R, −0.5 (±9.3) beats/min for R389G and +1.9 (±7.2) beats/min for G389G]. In conclusion, although the R389G polymorphism of the β1-adrenoceptor gene did not influence resting HR or BP in untreated OSA patients, it may modify the beneficial effects of CPAP therapy on these parameters.

Obesity Hypertension

IntroductionChildhood obstructive sleep apnoea (OSA) is a highly prevalent disorder that may directly contribute to the development of obesity, hypertension and renal injury. Although those associations seem to be clearer in adults, studies in children have revealed conflicting results and updated synthesis of the evidence is lacking. The aim of this systematic review is to summarise the available evidence on the effect of OSA on obesity, systemic blood pressure and kidney function, to help to elucidate whether respiratory interventions to correct OSA would have the potential to improve those outcomes.Methods and analysisA systematic literature review search was created by a medical librarian and peer-reviewed by a second librarian prior to running. Ovid Medline, Ovid Embase, CINAHL via EbscoHOST, Wiley Cochrane Library and ProQuest Dissertations and Theses Global were searched on 25 February 2020. Titles and abstracts will be screened by two independent reviewers for inclusion, followed by full-text screening of relevant articles. Studies in children will be included if they report data on OSA and weight, systemic blood pressure or kidney parameters. The extracted data will be combined for analysis and the information subcategorised in groups based on outcome. Risk of bias will be determined using tools specific to study methodology and certainty of the evidence using the Grading of Recommendations, Assessment, Development and Evaluations approach.Ethics and disseminationThis study will provide essential information for healthcare professionals to better understand the relationship between childhood OSA and changes in body mass index, systemic blood pressure and kidney function indicators. Our findings will be disseminated through conferences and publications. The results of this review may guide the initiation of new strategies and the development of future research studies. This research did not involve human subjects and therefore did not undergo research ethical review.PROSPERO registration numberCRD42020171186.
