Selective effects of CPAP on sleep apnoea-associated manifestations.
Visceral adiposity and obstructive sleep apnoea (OSA) may be independently associated with daytime sleepiness/low performance, insulin resistance, hypercytokinaemia, and/or hypertension. The objectives of this study are to simultaneously test these associations at baseline and after 3 months of continuous positive airway pressure (CPAP) therapy. ⋯ In obese sleep apnoeics, visceral fat is strongly associated with insulin resistance and inflammation. CPAP decreases sleepiness and moderates hypertension but does not affect visceral adiposity, insulin resistance, hypoadiponectinaemia or hypercytokinaemia, all of which are independent risk factors for cardiovascular disease and diabetes.
