This study was designed to investigate the prevalence of bronchial hyperreactivity (BH) in
patients with obstructive sleep apnea syndrome (OSAS), heavy snorers, and light snorers; its …

BACKGROUND: Obstructive sleep apnea syndrome (OSA) is associated with systemic and
upper airway inflammation. Pharyngeal inflammation has a potential role in upper airway …

Numerous studies have reported an association between nasal obstruction and obstructive
sleep apnea syndrome (OSAS), but the precise nature of this relationship remains to be …

Background The pathogenesis of daytime hypercapnia (Pa co 2≥ 45 mm Hg) may be
directly linked to the existence of obstructive sleep apnea syndrome (OSAS) per se …

Anecdotal reports suggest that obstructive sleep apnea syndrome (OSAS) patients may
suffer from frequent nocturnal gastroesophageal reflux (GER) and that nasal continuous …

The mechanisms responsible for the development of chronic hypercapnia in patients with
obstructive sleep apnea (OSA) are not well defined. Therefore, we tested the hypothesis that …

Obstructive sleep apnea syndrome (OSAS) is a condition characterized by recurrent
episodes of obstruction of the upper airway. The aim of this study was to evaluate whether …

To determine whether pulmonary hypertension (PH) can occur in obstructive sleep apnea
syndrome (OSAS) in the absence of lung or primary cardiac disease, we studied 27 patients …

Background: Obstructive sleep apnea syndrome (OSAS) has been shown to be associated
to upper and lower airways inflammation. Continuous positive airway pressure (CPAP) is the …

There have been very few studies assessing the long-term physiological effects of nasal
continuous positive airway pressure (CPAP) for the obstructive sleep apnoea syndrome. We …
