Chronic Kidney Disease and Sleeping Disordered Breathing (SDB)

Area of Science:

• Nephrology
• Cardiology
• Sleep Medicine

Background:

• Hypertension is a significant risk factor for cardiovascular mortality.
• Sleep-disordered breathing (SDB) and chronic kidney disease (CKD) are increasingly recognized as prevalent comorbidities.
• The interplay between these conditions requires further elucidation.

Purpose of the Study:

• To re-establish the link between hypertension and SDB, detailing prevalence, mechanisms, and potential for reversal.
• To re-establish the link between hypertension and CKD, examining prevalence, mechanisms, and reversal.
• To investigate the combined impact of CKD and SDB on hypertension and cardiovascular mortality.
• To explore the bidirectional relationship between CKD and SDB.

Main Methods:

• Literature review and synthesis of existing research.
• Analysis of epidemiological data and clinical studies.
• Mechanistic review of physiological pathways.

Main Results:

• Hypertension is closely linked with SDB and CKD, with shared pathophysiological mechanisms.
• Coexistence of SDB and CKD exacerbates hypertension and increases cardiovascular mortality risk.
• CKD and SDB exhibit a cyclical relationship, where each condition can worsen the other.

Conclusions:

• Addressing SDB and CKD is crucial for managing hypertension and reducing cardiovascular risk.
• The combined burden of SDB and CKD presents a significant public health challenge.
• Further research is warranted to develop integrated management strategies.
