[Improved control of hypertension and its effect on graft function in children after renal transplantation]

Area of Science:

• Pediatric Nephrology
• Transplantation Immunology
• Hypertension Management

Context:

• Hypertension is a common complication in pediatric renal transplant recipients (RTx), negatively impacting graft function and survival.
• Current control rates for hypertension in this population are suboptimal, affecting long-term outcomes.
• Effective management strategies are crucial for improving the health of children post-RTx.

Purpose:

• To assess the efficacy of an intensified antihypertensive treatment protocol in improving blood pressure control in children after RTx.
• To evaluate the impact of improved blood pressure control on graft function and survival in this cohort.
• To determine changes in medication requirements and specific drug classes used.

Summary:

• This 12-month interventional study involved 36 children post-RTx, monitoring ambulatory blood pressure (BP) and graft function.
• Uncontrolled hypertension prevalence decreased from 42% to 34% after intensifying antihypertensive drug regimens, including increased use of ACE-inhibitors.
• While day-time and night-time BP showed non-significant drops, the number of antihypertensive drugs per patient increased significantly.

Impact:

• The study demonstrates that intensified antihypertensive therapy can improve BP control in pediatric RTx patients.
• Although graft function showed a slight decline, it was less pronounced than in previous trials, suggesting a potential benefit of better BP management.
• Findings highlight the need for aggressive hypertension management to optimize outcomes in children following renal transplantation.
