Hypertension and Cardiovascular Risk Among Children with Chronic Kidney Disease

Area of Science:

• Pediatric Nephrology
• Cardiovascular Health in Chronic Illness
• Hypertension Research

Background:

• Cardiovascular disease (CVD) is the leading cause of mortality in children with chronic kidney disease (CKD).
• Hypertension is a significant contributor to CVD in this population, alongside obesity, dyslipidemia, and mineral bone disease.
• Recent research focuses on understanding hypertension and cardiovascular risk in pediatric CKD.

Purpose of the Study:

• To review recent (past five years) studies on hypertension and cardiovascular risk in children with CKD.
• To synthesize current understanding of blood pressure phenotypes and cardiovascular changes in pediatric CKD.
• To highlight the role of metabolic risk factors and lifestyle interventions.

Main Methods:

• Narrative review of studies published within the last five years.
• Analysis of findings from major cohort studies like CKiD and 4C.
• Inclusion of data from clinical trials such as HOT-KID.

Main Results:

• Cohort studies have advanced understanding of blood pressure phenotypes and cardiac/vascular changes in pediatric CKD.
• Dyslipidemia is an under-recognized metabolic risk factor requiring attention.
• Lifestyle interventions, particularly the DASH diet, are supported by trial data.
• The HOT-KID trial provides insights into optimal blood pressure targets.

Conclusions:

• Cardiovascular health is critical for the long-term outcomes of children with CKD.
• Effective management of hypertension and concurrent cardiovascular risk factors is essential.
• Some cardiovascular changes may persist post-transplantation, necessitating further research across all CKD stages.
