Cardiovascular abnormalities in children with autosomal dominant polycystic kidney disease

Area of Science:

• Pediatric Cardiology
• Nephrology
• Genetics

Background:

• Autosomal dominant polycystic kidney disease (ADPKD) is linked to cardiovascular issues in adults.
• Cardiac manifestations in pediatric ADPKD patients are not well-defined.
• Early identification of cardiac involvement in children with ADPKD is essential.

Purpose of the Study:

• To investigate the cardiac manifestations of ADPKD in a pediatric cohort.
• To assess the incidence of specific cardiovascular abnormalities in affected children.
• To establish correlations between cardiac findings and disease status in pediatric ADPKD.

Main Methods:

• Prospective, single-blinded echocardiographic evaluation of 154 children from 66 families with a parental history of ADPKD.
• Categorization of children into affected (renal cysts or gene carriers) and unaffected groups.
• Analysis of mitral valve prolapse, left ventricular mass index, systolic blood pressure, and congenital heart disease incidence.

Main Results:

• A 12% incidence of mitral valve prolapse in affected children versus 3% in unaffected siblings (P < 0.05).
• Significant correlation between left ventricular mass index and systolic blood pressure in affected children.
• Hypertensive ADPKD children exhibited larger left ventricular mass index compared to normotensive counterparts.
• Incidence of congenital heart disease was similar between affected (3.5%) and unaffected (2.9%) groups.

Conclusions:

• Cardiovascular abnormalities, including mitral valve prolapse, are present in childhood ADPKD.
• Systemic manifestations of ADPKD begin in early life.
• Clinicians should consider cardiac screening for pediatric ADPKD patients.
