HLA-G +3196 polymorphism as a risk factor for cell mediated rejection following heart transplant.

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]

We report central invasive haemodynamic parameters at rest and exercise during a 3 year follow‐up after HTx in a sub‐study of the SCandiavian Heart transplant Everolimus De novo stUdy with earLy calcineurin inhibitor avoidancE trial. We hypothesized that the nephroprotective properties, the less development of cardiac allograft vasculopathy (CAV), and the antifibrotic properties of EVR, in comparison with CNI‐based immunosuppression, would demonstrate favourable invasive haemodynamic profiles in patients at rest and during exercise.Methods and resultsNinety of 115 HTx recipients randomized to EVR or CNI treatment per...

Over the past four decades, cardiac transplantation has achieved considerable success in patients with end-stage heart disease; however, the incidence of antibody-mediated rejection (AMR) remains high and is considered to be an important cause of life-threatening cardiac allograft dysfunction.1-3

Abstract BACKGROUND: Because of the growing prevalence of terminal heart failure on the one hand and organ shortage on the other hand, an optimal care of heart transplant recipients based on the knowledge of potential risk factors not only early, but also in a long-term course after heart transplantation is of great importance. Therefore, the aim of the present study was to identify predisposing factors for late mortality in this patient collective. METHODS: Data from long-term heart transplant patients collected during follow-up visits in the current center were retrospectively analyzed. Clinical, laboratory...

AbstractReversible cerebral vasoconstriction syndrome (RCVS) after heart transplantation is a rare, but serious complication, because of a high risk for permanent neurological deficits or allograft rejection. A 48-year-old female who underwent orthotropic heart transplantation presented with a sudden severe headache 10  days after transplantation. Although magnetic resonance angiography (MRA) findings at initial symptom onset were normal, MRA finding at the next day revealed multifocal vasoconstriction of cerebral arteries. Tacrolimus-induced RCVS was strongly suspected, and tacrolimus was immediately discontinue d an...

Conclusion: LVMI reversed and MAP and renal function were normalized early after transplantation of a healthy kidney. However, LV fibrosis persisted, dissociating LV hypertrophy from LV fibrosis within 6 weeks. Elucidating cardiac ECM dynamics in CKD patients, although challenging, appears promising.

Abstract Indoleamine 2, 3-dioxygenase (IDO)-mediated regulation of tryptophan metabolism plays an important role in immune tolerance in transplantation, but it has not been elucidated which mechanism specifically induces the occurrence of immune tolerance. Our study revealed that IDO exerts immunosuppressive effects through two pathways in mouse heart transplantation, 'tryptophan depletion' and 'tryptophan metabolite accumulation'. The synergism between IDO+ DC and TC (tryptophan catabolic products) has stronger inhibitory effects on T lymphocyte proliferation and mouse heart transplant rejection than the two inte...

We describe a ca se series in which 2 patients received kidney transplants while on veno‐arterial ECMO support for PGD after heart transplant. Both patients are alive more than 1 year following transplant, with good cardiac and renal function and no signs of cardiac rejection. Kidney transplant surgery is safe for patients on veno‐arterial ECMO support for cardiac PGD. It allows the heart recipient to receive a kidney from the same donor with both immunologic and survival advantages.

Conclusion: Quantitative PET analysis, and particularly MFR, has diagnostic and prognostic utility after heart transplantation. Preserved MFR identifies low-risk patients, whereas the presence of multiple abnormal parameters identifies high-risk patients.

We read with great interest the article by Van Keer et al. assessing the long term outcomes of cardiac allograft vasculopathy (CAV).1 We commend the authors on their large well-characterized dataset over a 25-year period, and for contributing knowledge on an important disease we do not yet fully understand. Importantly, this is one of the largest analysis and external validation of the ISHLT CAV classification system.2 We believe a few points merit further consideration.
