Diastolic strain imaging: a new non-invasive tool to detect subclinical myocardial dysfunction in early cardiac allograft rejection

In conclusion, early global diastolic strain rate is the most sensi tive parameter to detect subclinical myocardial dysfunction during early periods of pre-1R prior to biopsy confirmed 1R-ACR. GDSRe is a potential new tool for non-invasive screening of early post-transplant cardiac allograft rejection.

Authors: Tönshoff B Abstract Introduction: The goal of immunosuppressive therapy post-transplantation in pediatric renal transplant recipients is to prevent acute and chronic rejection while minimizing drug side effects. Most therapies alter immune response mechanisms but are not immunologically specific, and a careful balance is required to find the dose that prevents rejection of the graft, while minimizing the risks of over-immunosuppression leading to infection and cancer.Areas covered: This review article focuses on immunosuppressive therapy in pediatric renal transplant recipients, but many aspects can b...

CONCLUSION: Vitamin D3 administered as an immunosuppressive agent, when combined with monoclonal antibody treatment, may protect heart grafts from memory T cell responses in a secondary heart transplant model. PMID: 31953155 [PubMed - as supplied by publisher]

CONCLUSION: The HLA-G +3196 G allele was identified as a risk factor for CMR diagnosis. HLA-G may have a role in therapeutic/diagnostic strategies against transplant rejection. PMID: 31928922 [PubMed - as supplied by publisher]

Bruneval, Shaida Varnous, R. Guillemain, P. Rouvier, J.L. Taupin, X. Jouven, A. LoupyBackgroundThe diagnosis of cardiac allograft rejection is based on the histological analysis of a myocardial tissue sample obtained by endomyocardial biopsy (EMB), an invasive procedure at risk of complications. Our aim is to enable the shift from a protocol biopsy approach, to a precision medicine approach, in which the need for EMB is tailored to each...

Background. Two or more early rejections (1 y) have been associated with coronary artery vasculopathy (CAV) in pediatric heart transplant (HT) recipients. We hypothesized that clinical rejection defined by concurrent new-onset heart failure or left ventricular systolic dysfunction is more strongly associated with future CAV than rejection diagnosed on protocol biopsy. Methods. We identified all subjects

Conclusions. These data suggest that pDC-induced regulatory T cells are dependent on downstream signaling effects and on strain-dependent, MHC class II disparity with naive T cells, which may explain organ- and strain-specific differences in spontaneous tolerance.

Cardiac Allograft Vasculopathy (CAV) is a major cause of chronic cardiac allograft failure. Invasive coronary angiography (ICA) and intravascular ultrasound (IVUS) are the current diagnostic methods. Myocardial perfusion MRI has become a promising non-invasive method to evaluate myocardial ischemia, but has not been thoroughly validated in CAV. Our objective was to assess the repeatability of myocardial rest-perfusion MRI in healthy volunteers and its feasibility in detecting CAV in transplant patients (Tx).
