Delivery of FK506-loaded PLGA nanoparticles prolongs cardiac allograft survival

In conclusion, PLGA-FK506-NPs are a promising formulation for spleen and lymph node delivery and have potential use in the treatment of cardiac allograft acute rejection.Graphical abstract

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...

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.

AbstractBackgroundWe previously demonstrated high diagnostic accuracy of Rubidium-82 positron emission tomography (PET) myocardial blood flow (MBF) quantification for CAV. The purpose of this study was to validate multiparametric PET detection of CAV by combined rate-pressure-product-corrected myocardial flow reserve (cMFR), stress MBF, and coronary vascular resistance (CVR) assessment.Methods and ResultsDiagnostic CAV cut-offs of cMFR

Restrictive allograft syndrome (RAS) after lung transplantation (LTx) is associated with the poorer graft survival in patients with chronic lung allograft dysfunction (CLAD). Nevertheless, its diagnostic criteria remain not well defined after single-LTx (SLTx). Hence, we studied an SLTx cohort with CLAD to investigate the utility of both CT-score/volume measures and functional spirometric criteria for early identifying RAS in this population.

Restrictive allograft syndrome (RAS) after lung transplantation (LTx) is associated with the poorer graft survival in patients with chronic lung allograft dysfunction (CLAD). Nevertheless, its diagnostic criteria have not been clearly defined after single-LTx (SLTx). Hence, we studied an SLTx cohort with CLAD to investigate the utility of both computed tomography (CT)-score/volume measures and functional spirometric criteria for the early identification of RAS in this population.

Checkpoint regulators are thought to actively participate in the immune defense of infections, prevention of autoimmunity, transplantation, and tumor immune evasion. Maternal-fetal immunotolerance represents a real immunological chal...

Restrictive allograft syndrome (RAS) has been identified as a chronic lung allograft dysfunction (CLAD) with the worst prognosis after lung transplantation (LTx). Diagnostic criteria of RAS have been proposed in double-LTx (DLTx), but how to apply these criteria in single (S)-LTx remain debatable. Hence, there is a need to validate and refine these criteria in SLTx. Our aim was to investigate functional, allosensitization, and CT-scan abnormalities patterns in SLTx recipients with RAS, as compared to single LTx with BOS or in stable condition.

Background: We evaluated the diagnostic and prognostic value of quantification of myocardial flow reserve (MFR) with positron emission tomography (PET) in orthotopic heart transplant patients. Methods and Results: We retrospectively identified orthotopic heart transplant patients who underwent rubidium-82 cardiac PET imaging. The primary outcome was the composite of cardiovascular death, acute coronary syndrome, coronary revascularization, and heart failure hospitalization. Cox regression was used to evaluate the association of MFR with the primary outcome. The relationship of MFR and cardiac allograft vasculopathy severi...
