Abdominal adipose tissue was assessed using magnetic resonance imaging. Intramyocellular lipid (IMCL) and skeletal muscle creatine were assessed using\n                    <jats:sup>1<\/jats:sup>\n                    H\u2010magnetic resonance spectroscopy. Fasting venous and arterial blood were collected. Glucose control was assessed using the homeostatic model. A subgroup of six patients were also evaluated for skeletal muscle pH, phosphocreatine (PCr) and mitochondrial function using\n                    <jats:sup>31<\/jats:sup>\n                    P\u2010magnetic resonance spectroscopy.

Regular CPAP use also produced an increase in skeletal muscle creatine and resting PCr and a decrease in muscle pH. Neither the regular nor irregular CPAP users showed any change in IMCL content, insulin sensitivity scores or mitochondrial function.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:\u2002<\/jats:bold>\n                    These data show that regular CPAP therapy reduces visceral adipose tissue and leptin and improves skeletal muscle metabolites. In obese patients with severe OSAS, regular CPAP use does not improve glucose control, suggesting that the influence of obesity on glucose control dominates over any potential effect of OSAS.\n                  <\/jats:p>","DOI":"10.1111\/j.1463-1326.2006.00649.x","type":"journal-article","created":{"date-parts":[[2006,9,8]],"date-time":"2006-09-08T15:48:59Z","timestamp":1157730539000},"page":"679-687","source":"Crossref","is-referenced-by-count":83,"title":["Influence of constant positive airway pressure therapy on lipid storage, muscle metabolism and insulin action in obese patients with severe obstructive sleep apnoea syndrome"],"prefix":"10.1111","volume":"9","author":[{"given":"M.
