WCN24-1133 A PROSPECTIVE OBSERVATIONAL STUDY OF PREVALENCE AND RISK FACTORS OF OBSTRUCTIVE SLEEP APNOEA IN CHRONIC KIDNEY DISEASE AND ITS CO-RELATION WITH RENAL FUNCTION

Obstructive sleep apnea (OSA) occurs in at least 50% to 60% of patients with chronic kidney disease (CKD), which is 10 times higher than in the general population .The high incidence of nocturnal hypoxiemia associated with OSA causes oxidative stress, RAAS activation and endothelial dysfunction. This contributes to both loss of kidney function and increased cardiovascular morbidity in patients with CKD. This study aimed to estimate the prevalence of OSA in patients with CKD and analyse the distribution of OSA according to its severity in different stages of CKD.
