Pathogenesis of hypertension in autosomal dominant polycystic kidney disease
1University of Colorado School of Medicine, Denver.
Insights
Autosomal dominant polycystic kidney disease (ADPKD) often involves hypertension, likely originating in renal vasculature. Early hypertension detection and control in ADPKD may improve outcomes and survival.
Area of Science:
- Nephrology
- Cardiovascular Medicine
- Genetics
Background:
- Autosomal dominant polycystic kidney disease (ADPKD) affects approximately 1 in 400 individuals in the United States.
- Hypertension is the most common associated disorder in ADPKD.
- Renal cyst expansion is linked to hypertension development, with pathogenesis likely in the renal vasculature.
Purpose of the Study:
- To explore the role of the renin-angiotensin-aldosterone system in ADPKD-related hypertension.
- To investigate the relationship between hypertension and end-organ damage in ADPKD.
- To emphasize the importance of early hypertension detection and management in ADPKD patients.
Main Methods:
- Review of accumulating evidence on the renin-angiotensin-aldosterone system's involvement.
- Analysis of the association between hypertension and end-organ damage (left ventricular hypertrophy, renal insufficiency).
- Focus on clinical implications for patient outcomes.
Main Results:
- The renin-angiotensin-aldosterone system is increasingly recognized as crucial for hypertension development and maintenance in ADPKD.
- Hypertension in ADPKD is associated with significant end-organ damage, including left ventricular hypertrophy and progressive renal insufficiency.
- These findings underscore the link between hypertension and adverse cardiovascular and renal outcomes.
Conclusions:
- Early detection and adequate control of hypertension are critical in managing ADPKD.
- Effective hypertension management may lead to improved cardiovascular and renal outcomes.
- Focusing on hypertension control could enhance patient survival in ADPKD.
Abstract:
Autosomal dominant polycystic kidney disease is a common (approximately 1 in 400 individuals in the United States) inherited disorder, in which hypertension is the most often associated disorder. Although the development of hypertension originates with expansion of renal cysts, it most likely has its pathogenesis in the renal vasculature. Evidence is now accumulating that the renin-angiotensin-aldosterone system is important in the development and maintenance of hypertension in this disorder. End-organ damage including left ventricular hypertrophy and progressive renal insufficiency appear to be related to the presence of hypertension in ADPKD. A focus on early detection and adequate control of hypertension in ADPKD, therefore, may be associated with improved cardiovascular and renal outcomes as well as increased patient survival in ADPKD.
