Review article: Managing sleep apnoea in kidney diseases.
A higher prevalence of sleep apnoea (SA) has been observed in the chronic kidney disease (CKD) population compared with estimates in the general population. Increased rates of SA have been described in patients with various renal-related diagnoses including dialysis, renal transplant, early-stage CKD and proteinuria. The mechanism or underlying aetiology for this association is different for each type of kidney disease. The extracellular fluid volume and metabolic derangements that characterize the uremic state likely contributes to SA in the dialysis population. SA causing direct renal insults from haemodynamic changes, ischaemic stress, or an intermediary condition such as hypertension, can lead to early CKD and proteinuria. While renal transplantation has cured SA in some patients, the post-transplant state is itself a risk factor for SA. The high prevalence of SA in kidney disease and the associated clinical implications warrant vigilance in diagnosis and treatment of SA in the CKD patient. This review focuses on the prevalence of SA in patients with CKD including dialysis and transplant patients, and those with early-stage CKD and proteinuria. SA may vary in form and aetiology depending on type or stage of CKD. Based on these associations, we discuss our rationale for recommendations on screening and management of SA specific to the CKD population.
