About
The purpose of this study is to investigate the effect of 3 months of continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea (OSA) in moderate to severe cases in patients with chronic kidney disease. The effect is evaluated on blood pressure levels, particularly nocturnal blood pressure, both central and peripheral, and renal function, including the kidneys treatment of salt and water.
Hypothesis:
4 Quality of life is improved during treatment with CPAP.
Full description
Approximately 30 patients with chronic kidney disease and obstructive sleep apnea in moderate to severe degree is examined with central and peripheral 24-h blood pressure monitoring, 1 night home polygraphy to determine the degree of sleep apnea, blood and urine samples to determine levels of u-AQP2, u-ENAC, plasma renin concentration (PRC), s-angiotensin II (p-angII), p-aldosterone, p-vasopressin (p-avp) and p-endothelin, before the start treatment with CPAP for sleep apnea.
After 3 month of treatment all the above described is repeated to determine effects of CPAP treatment on blood pressure levels during the day, changes i apnea hypopnea index (AHI) and the kidneys treatment of salt and water.
