- Early initiation of everolimus with calcineurin inhibitor therapy has been shown to reduce the progression of cardiac allograft vasculopathy (CAV) in de novo heart transplant recipients. The effect of de novo everolimus therapy and early total elimination of calcineurin inhibitor therapy has, however, not been investigated and is relevant given the morbidity and lack of efficacy of current protocols in preventing CAV. This 12-month multicenter Scandinavian trial randomized 115 de novo heart transplant recipients to everolimus with complete calcineurin inhibitor elimination 7-11 weeks after HTx or standard cyclosporine immunosuppression. Ninety-five (83%) patients had matched intravascular ultrasound examinations at baseline and 12 months. Mean (SD) recipient age was 49.9 +/- 13.1 years. The everolimus group (n=47) demonstrated significantly reduced CAV progression as compared to the calcineurin inhibitor group (n=48) (Maximal Intimal Thickness 0.03 +/- 0.06 and 0.08 +/- 0.12mm, Percent Atheroma Volume 1.3 +/- 2.3 and 4.2 +/- 5.0%, Total Atheroma Volume 1.1 +/- 19.2mm(3) and 13.8 +/- 28.0mm(3) [all p-values0.01]). Everolimus patients also had a significantly greater decline in levels of soluble tumor necrosis factor receptor-1 as compared to the calcineurin inhibitor group (p=0.02). These preliminary results suggest that an everolimus-based CNI-free can potentially be considered in suitable de novo HTx recipients.

- To investigate the survival of heart transplant (HTx) recipients during different time periods in Sweden. We hypothesized that the survival for HTx recipients has improved following advancements in the management of these patients.Data was obtained through the database of the organ exchange organization Scandiatransplant. All patients who underwent HTx in Sweden between Jan 1988 and Dec 2017 were included. Patients were divided into five cohorts of six-year periods each.A total of 1137 HTx recipients were included. Main causes of transplantation were dilated cardiomyopathy (44 %) and ischemic heart disease (18 %). Retransplantation constituted a small portion of the overall total (2 %). The cohorts were similar in terms of age and gender, while later cohorts had higher BMI, lower GFR and longer ischemia time (Tab. 1). The later cohorts received organs from older donors (Tab. 1). The amount of heart transplantations performed in Sweden has increased with time (Tab. 1). Log-rank test comparing the survival curves was able to show improved survival during later eras (Fig. 1).Survival among HTx recipients has significantly improved in Sweden over time, despite less favorable recipients and donor characteristics. This was related to both reduced postoperative mortality and also improved long-time survival.

- Objective: There is a paucity of data on heart transplantation (HTx) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC), and specific recommendations on indications for listing ARVC patients for HTx are lacking. In order to delineate features pertinent to HTx assessment, we explored the pre-HTx characteristics and clinical history in a cohort of ARVC patients who received heart transplants. Methods: Data from 31 ARVC/HTx patients enrolled in the Nordic ARVC Registry, transplanted between 1988 and 2014 at a median age of 46. years (14-65), were compared with data from 152 non-transplanted probands with Definite ARVC according to 2010 Task Force Criteria from the same registry. Results: The HTx patients were younger at presentation, median 31 vs. 38. years (p = 0.001). There was no difference in arrhythmia-related events. The indication for HTx was heart failure in 28 patients (90%) and ventricular arrhythmias in 3 patients (10%). During median follow-up of 4.9. years (0.04-28), there was one early death and two late deaths. Survival was 91% at 5. years after HTx. Age at first symptoms under 35. years independently predicted HTx in our cohort (OR = 7.59, 95% CI 2.69-21.39, p <. 0.001). Conclusion: HTx in patients with ARVC is performed predominantly due to heart failure. This suggests that current 2016 International Society for Heart and Lung Transplantation heart transplant listing recommendations for other cardiomyopathies could be applicable in many cases when taking into account the haemodynamic consequences of right ventricular failure in conjunction with ventricular arrhythmia.

- Tens of thousands of patients with advanced lung diseases may be eligible to be considered as potential candidates for lung transplant around the world each year. The timing of referral, evaluation, determination of candidacy, and listing of candidates continues to pose challenges and even ethical dilemmas. To address these challenges, the International Society for Heart and Lung Transplantation appointed an international group of members to review the literature, to consider recent advances in the management of advanced lung diseases, and to update prior consensus documents on the selection of lung transplant candidates. The purpose of this updated consensus document is to assist providers throughout the world who are caring for patients with pulmonary disease to identify potential candidates for lung transplant, to optimize the timing of the referral of these patients to lung transplant centers, and to provide transplant centers with a framework for evaluating and selecting candidates. In addition to addressing general considerations and providing disease specific recommendations for referral and listing, this updated consensus document includes an ethical framework, a recognition of the variability in acceptance of risk between transplant centers, and establishes a system to account for how a combination of risk factors may be taken into consideration in candidate selection for lung transplantation.

- In a randomized, open-label trial, everolimus was compared to cyclosporine in 115 de novo heart transplant recipients. Patients were assigned within 5 days posttransplant to low-exposure everolimus (3-6 ng/mL) with reduced-exposure cyclosporine (n 56), or standard-exposure cyclosporine (n = 59), with both mycophenolate mofetil and corticosteroids. In the everolimus group, cyclosporine was withdrawn after 7-11 weeks and everolimus exposure increased (6-10 ng/mL). The primary efficacy end point, measured GFR at 12 months posttransplant, was significantly higher with everolimus versus cyclosporine (mean +/- SD: 79.8 +/- 17.7 mL/min/1.73m 2 vs. 61.5 +/- 19.6 mL/min/1.73m 2; p<0.001). Coronary intravascular ultrasound showed that the mean increase in maximal intimal thickness was smaller (0.03 mm [95% CI 0.01, 0.05 mm] vs. 0.08 mm [95% CI 0.05, 0.12 mm], p = 0.03), and the incidence of cardiac allograft vasculopathy (CAV) was lower (50.0% vs. 64.6%, p = 0.003), with everolimus versus cyclosporine at month 12. Biopsy-proven acute rejection after weeks 7-11 was more frequent with everolimus (p = 0.03). Left ventricular function was not inferior with everolimus versus cyclosporine. Cytomegalovirus infection was less common with everolimus (5.4% vs. 30.5%, p<0.001); the incidence of bacterial infection was similar. In conclusion, everolimus-based immunosuppression with early elimination of cyclosporine markedly improved renal function after heart transplantation. Since postoperative safety was not jeopardized and development of CAV was attenuated, this strategy may benefit long-term outcome.

Tidskriftsartikel (refereegranskat)abstract
- In a randomized, open-label trial, de novo heart transplant recipients were randomized to everolimus (3-6ng/mL) with reduced-exposure calcineurin inhibitor (CNI; cyclosporine) to weeks 7-11 after transplant, followed by increased everolimus exposure (target 6-10ng/mL) with cyclosporine withdrawal or standard-exposure cyclosporine. All patients received mycophenolate mofetil and corticosteroids. A total of 110 of 115 patients completed the 12-month study, and 102 attended a follow-up visit at month 36. Mean measured GFR (mGFR) at month 36 was 77.4mL/min (standard deviation [SD] 20.2mL/min) versus 59.2mL/min (SD 17.4mL/min) in the everolimus and CNI groups, respectively, a difference of 18.3mL/min (95% CI 11.1-25.6mL/min; p < 0.001) in the intention to treat population. Multivariate analysis showed treatment to be an independent determinant of mGFR at month 36. Coronary intravascular ultrasound at 36 months revealed significantly reduced progression of allograft vasculopathy in the everolimus group compared with the CNI group. Biopsy-proven acute rejection grade 2R occurred in 10.2% and 5.9% of everolimus- and CNI-treated patients, respectively, during months 12-36. Serious adverse events occurred in 37.3% and 19.6% of everolimus- and CNI-treated patients, respectively (p=0.078). These results suggest that early CNI withdrawal after heart transplantation supported by everolimus, mycophenolic acid and steroids with lymphocyte-depleting induction is safe at intermediate follow-up. This regimen, used selectively, may offer adequate immunosuppressive potency with a sustained renal advantage. A follow-up study of the SCHEDULE trial, which randomized de novo heart transplant recipients to everolimus with cyclosporine discontinuation or to standard-exposure cyclosporine, shows that measured glomerular filtration rate remains significantly higher in the everolimus group at three years posttransplant, with significantly reduced progression of allograft vasculopathy compared to cyclosporine therapy.

- Medical treatment for cardiac amyloidosis (CA) is evolving rapidly. Heart transplantation can be a valid option when followed by transplantation of bone marrow or liver, dependent on the type and origin of the amyloid protein. Thus, accurate typing of amyloidosis has implications for treatment, prognosis, and genetic counseling. Although non-invasive diagnostic techniques can type CA, endomyocardial biopsy (EMB) may be needed in the case of equivocal imaging findings or discordant data. We aimed to define the role of mass spectrometry (MS) for diagnosis and subtyping of CA.Nineteen previously diagnosed CA cases, who underwent EMB at Sahlgrenska University Hospital (SU), Gothenburg, between the beginning 1990s and 2016, were selected. MS analysis, modified from was conducted on duplicate samples from myocardial tissue for each case included.1 Clinical features and diagnoses were used as gold standard and compared to the MS findings.Clinical diagnosis and the MS analysis agreed in 14 cases (73.7 %); in 3/19 (15.8 %) diagnosis was unclear or discordant (Fig.1). MS analysis revealed that transthyretin (TTR) amyloidosis was the most abundant amyloid protein in the samples examined (9/19; 47.3 %), whereas the AA subtype only occurred in 1 case (5.2 %). The AL κ type amyloidosis occurred in 3 cases (15.8 %), and AL λ type in six cases (31.6 %). These results strongly correlated with the clinical features in all patients. Clinical diagnosis could not be retrieved from the medical records in 2 cases (10.4 %). Additional 20 patients with clinical CA are presently under study.MS analysis of a small amount of endomyocardial tissue can be used to subtype CA with a high diagnostic validity. The method differentiated between TTR, SAA and Ig light chain amyloidosis. AL κ and AL λ identities correlated to those found in serum and urine electrophoreses. MS can therefore be of use to subtype CA for cases in which clinical findings are inconclusive. 1) Brambilla F et al. Blood. 2012 Feb 23;119(8):1844-7.
