Identifying microRNAs to improve heart transplant outcomes in children

Optimal Pediatric Heart Transplant Immunosuppression With MicroRNAs

Observational Inova Health Care Services · NCT06532890

This study is trying to find specific microRNAs in the blood of children who have had heart transplants to see if they can help predict infections and rejection of the new heart.

What this trial studies

This observational study aims to identify circulating microRNAs that can help characterize the immune state in pediatric heart transplant patients and predict the likelihood of developing infections and graft rejection. It will involve a prospective, multicenter cohort of 100-150 patients from various transplant centers across the United States, with blood samples collected at specified intervals and during clinical events. The goal is to develop a non-invasive genomic blood test to monitor patients post-transplant, thereby reducing complications associated with immunosuppression.

Who should consider this trial

Good fit: Ideal candidates are pediatric patients aged 18 years or younger who have received a heart transplant within the last month.

Not a fit: Patients who have received multi-organ transplants or have ongoing infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and management of pediatric heart transplant patients, reducing the risk of infections and rejection.

How similar studies have performed: Other studies have shown promise in using microRNAs as biomarkers in various conditions, suggesting potential success for this novel approach in pediatric heart transplantation.
