Obstructive sleep apnoea (OSA) is a recognised risk factor for hypertension (HT). The current authors investigated confounders of this association in a sex-balanced community-based sample of patients with HT (n=161) from the Skaraborg Hypertension and Diabetes Project (n=1,149) and normotensive controls (n=183) from an age and sex stratified community-based population sample (n=1,109). All part...

Obstructive sleep apnoea (OSA) is associated with high cardiovascular morbidity and mortality. Several randomised controlled trials have shown that continuous positive airway pressure (CPAP) treatment of OSA reduces blood pressure (BP). This randomised, sham-placebo controlled crossover trial assesses whether CPAP produces a similar clinically significant fall in BP in hypertensive OSA patients...

Obstructive sleep apnoea (OSA) is associated with increased risk of dysglycaemia but the intimate link of these conditions with obesity makes discerning an independent relationship between them challenging. Glycosylated haemoglobin (HbA1c) levels predict adverse cardiovascular outcomes in nondiabetics but there is a lack of population-level data exploring the relationship of HbA1c with OSA. A c...

Objective: To establish the association between airway inflammation and severity of obstructive sleep apnoea (OSA) in children. Methods: Consecutive children presenting with symptoms suggestive of OSA were recruited. They completed a sleep apnoea symptom questionnaire, underwent physical examination, spirometry, sputum induction and an overnight polysomnography. Adequate sputum contained ,50% s...

Obstructive sleep apnoea (OSA) is highly prevalent, with recent general population studies indicating that up to 50% of males and 23% of females have moderate or severe sleep disordered breathing (SDB) based on an apnoea–hypopnoea index (AHI) of >15 events·h [1, 2]. OSA is recognised as an independent risk factor for systemic hypertension [3] and a nondipping nocturnal blood pressure profile is...

Mucosal haemangiomas are unusual and typically involve frequently traumatised areas such as the lip, buccal mucosa and lateral borders of the tongue. Uvular haemangioma is rare and to our knowledge, has never been reported to cause obstructive sleep apnoea (OSA). We report an unusual case of uvular haemangioma causing loud habitual snoring and symptoms suggestive of OSA. This case report illust...

The aim of the present study was to examine the natural evolution of primary snoring and obstructive sleep apnoea (OSA) in adult male patients. Retrospective analysis was performed on 160 untreated patients with primary snoring and mild, moderate and severe OSA who had two polysomnographic recordings. The mean time between recordings (TBR) was 5.1+/-3 yrs. The mean apnoea/hypopnoea index (AHI),...

BACKGROUND Childhood obstructive sleep apnoea (OSA) is increasingly being recognised. Its effects on blood pressure (BP) elevation and hypertension are still controversial. OBJECTIVE To evaluate the association between OSA and ambulatory BP in children. METHODS Children aged 6-13 years from randomly selected schools were invited to undergo overnight sleep study and ambulatory BP monitoring ...

The aim of the present study was to explore morbidity and healthcare utilisation among young adult males with obstructive sleep apnoea (OSA) compared with middle-aged OSA patients over the 5-yr period preceding diagnosis. A prospective case-control study was performed; 117 young (22-39-yr-old) males with OSA were matched with 117 middle-aged (40-64-yr-old) OSA males for body mass index, apnoea/...
