Identification of Heart Transplant Rejection Subtypes With Circulating MicroRNAs.

ABSTRACT:

Background

Circulating microRNAs are promising biomarkers of acute cellular rejection (ACR) and antibody-mediated rejection (AMR) in heart transplantation. The study objective was to assess the characteristics and diagnostic performance of previously identified microRNAs and clinical rejection scores (CRS) in distinct blood samples obtained at the time of an endomyocardial biopsy (EMB).

Methods

In the 5-center, prospective, longitudinal cohort study, GRAfT (Genomic Research Alliance for Transplantation), microRNA sequencing was performed on blood samples. The previously identified microRNAs associated with ACR (n=12) and AMR (n=17) were used to fit a logistic regression model to the current cohort, and the scores were scaled from 0 to 100. Diagnostic performance of ACR and A
