Hypertension in Pediatric Solid Organ Transplant Recipients

Area of Science:

• Pediatric Nephrology
• Transplant Cardiology
• Immunology

Background:

• Hypertension (HTN) is a significant complication post-pediatric solid organ transplant (SOTx).
• Current pediatric HTN guidelines lack specific recommendations for SOTx recipients.
• HTN is prevalent, underdiagnosed, and undertreated in kidney transplant (KTx) recipients, particularly when using ambulatory blood pressure monitoring (ABPM).

Purpose of the Study:

• To review the current literature on hypertension following pediatric solid organ transplant (SOTx).
• To examine the definition, prevalence, risk factors, outcomes, and treatment of HTN in pediatric SOTx recipients.
• To highlight the need for improved monitoring and management strategies.

Main Methods:

• Literature review of current research on pediatric SOTx and hypertension.
• Analysis of factors contributing to HTN, including pre-transplant status, demographics, weight, and immunosuppression.
• Examination of associated cardiovascular end-organ damage and long-term outcomes.

Main Results:

• HTN is multifactorial in SOTx recipients, influenced by pre-transplant HTN, age, sex, race, weight, and immunosuppression.
• HTN is linked to subclinical cardiovascular damage like left ventricular hypertrophy and arterial stiffness.
• Limited data exist on long-term outcomes and optimal management strategies for HTN in this population.

Conclusions:

• Post-transplant hypertension in pediatric SOTx recipients requires increased clinical attention, including routine monitoring and ABPM.
• Further research is essential to understand long-term outcomes and establish effective treatment goals.
• More investigation is needed specifically for HTN in non-kidney pediatric SOTx populations.
