Summary

The goal of thisobservational study is to systematically assess the presence and distribution of CMR-defined inflammation and fibrosis in clinically stable HT recipients with DSA detected during active screening for AMR surveillance. The main outcome is to study the prevalence of fibrosis, edema and of altered T1 mapping values in patients with DSA and the prevalence of patients with DSA among all the enrolled patients

Detailed description

This is a multicentric prospective study with experimental sample collection. Therapy and procedures will be performed according to clinical practice and current guidelines. Caring physicians will be blinded to the results of study specific assays, which will not be used to change standard cynical decision making. Patients will be enrolled in the study at the time of the DSA assay performed in the context of standard surveillance (yearly monitoring for anti-HLA antibodies is recommended by current guidelines and is part of routine clinical practice). At study entry patients will receive blood sampling to assay dd-cfDNA (centralized laboratory) and T-reg populations (local laboratory). Clinical characteristics, medical history, and results of standard laboratory tests will be collected at baseline.
