Hypertension in Pediatric Dialysis Patients: Etiology, Evaluation, and Management

Area of Science:

• Pediatric Nephrology
• Cardiovascular Health in Dialysis Patients

Background:

• Hypertension is a significant modifiable risk factor for cardiovascular disease, the leading cause of morbidity and mortality in pediatric dialysis patients.
• Effective management of hypertension is critical for improving long-term outcomes in this vulnerable population.

Purpose of the Study:

• To review the epidemiology, pathophysiology, and current management strategies for hypertension in children undergoing dialysis.
• To highlight recent advancements and ongoing challenges in controlling blood pressure in pediatric dialysis patients.

Main Methods:

• The review synthesizes current literature on interdialytic blood pressure monitoring, including ambulatory blood pressure monitoring as the gold standard.
• It examines the role of assessing dry weight and achieving euvolemia as primary therapeutic goals.
• The review also discusses the use of antihypertensive medications and native nephrectomies for persistent hypertension.

Main Results:

• Achieving dry weight and managing fluid balance (limiting interdialytic weight gain and optimizing ultrafiltration rate) are key to controlling hypertension.
• Tools for assessing volume status beyond clinical evaluation show promise in achieving euvolemia.
• Antihypertensive medications and, in some cases, native nephrectomies are necessary for persistent hypertension.

Conclusions:

• Euvolemia, achieved through careful fluid management and dry weight assessment, is the cornerstone of hypertension management in pediatric dialysis.
• Antihypertensive pharmacotherapy and surgical interventions like native nephrectomies are important for refractory cases.
• Further research is needed to establish optimal antihypertensive drug classes and ultrafiltration rates to reduce cardiovascular risk in this population.
