Is only fixed positive airway pressure a robust tool for kidney protection in patients with obstructive sleep apnea?

The prevalence of chronic kidney disease (CKD) (1) has increased dramatically in recent years, and is unfortunately expected to continue to increase. Increased CKD prevalence is closely related to rapid increase in hypertension, diabetes, obesity, and metabolic syndrome as well as the aging society (1,2). The public health burden of CKD is not limited to its considerable economic burden for renal replacement therapy but CKD has a major impact on the risk of premature death for cardiovascular diseases (3).
