While short-term allograft survival has improved significantly in recent years, there has been little improvement in long-term survival after liver transplantation. A growing body of evidence on factors influencing the long-term outcomes and the safety profiles of existing immunosuppressive agents after liver transplant points to a need to continue searching for alternative strategies. The calcineurin inhibitors (CNIs) (cyclosporine and tacrolimus) currently represent the backbone of most immunosuppressor regimens. They have had a revolutionary effect on the overall success of transplantation, as is reflected in greatly reduced rates of acute rejection. However, the CNIs have significant toxici - ties that produce renal dysfunction, cardiovascular disease, and other unwanted effects, such as malignancies. The recognition of these risk factors has sparked interest in regimens that limit exposure to CNIs. Nowadays, the use of immunosuppressive drugs with different mechanisms of action, which allow for a reduction or avoidance of CNIs, is common. Everolimus, which belongs to the mammalian target-of-rapamycin inhibitor family and is best known for its use in kidney and heart transplantation, has recently been approved for liver transplantation. This overview discusses the emerging evidence on the role of everolimus in the prevention of rejection after liver transplantation, in de novo transplants, conversion regimens, or as a rescue therapy. In addition, some of the most relevant and current clinical problems related to everolimus in this field are discussed.","PeriodicalId":41597,"journal":{"name":"Transplant Research and Risk Management","volume":"6 1","pages":"31-43"},"PeriodicalIF":0.9,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/TRRM.S40152","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68495466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common indications for transplantation in children are renal developmental anomalies, obstructive uropathy, and focal segmental glomerulosclerosis. Living donor kidney transplants are often performed pre-emptively and offer excellent graft function. Policy changes in deceased-donor kidney allocation have increased the proportion of such transplants in pediatric recipients. Adequate pretransplant workup along with evaluation of urologic abnormalities is imperative in achieving good outcomes. Overall, patient and graft outcomes after kidney transplantation have improved, with five-year deceased donor and living donor graft survivals of 78.8% and 84.3%, respectively. Improvements in induction and maintenance immunosuppression have contributed to the gradual improvement in outcomes. Unique challenges in pediatric recipients include increased graft thrombosis, adverse growth, and abnormal development relating to immunosuppression, increased rejection due to nonadherence, increased susceptibility to opportunistic infections, and post-transplant malignancy. This review focuses on the current practices and outcomes in pediatric kidney transplantation in North America. We discuss the indications for transplantation, the evaluation process, some key surgical and immunologic considerations, and the common risk factors for graft dysfunction.","PeriodicalId":41597,"journal":{"name":"Transplant Research and Risk Management","volume":"5 1","pages":"21-31"},"PeriodicalIF":0.9,"publicationDate":"2013-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/TRRM.S34043","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68495220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Selection of appropriate candidates requires consideration of specific clinical characteristics, prognosis in the absence of transplantation, and likely outcome of transplantation. Increased availability of alternatives to transplantation for end-stage patients and the many efforts to increase the supply of donor organs have complicated decision making for selecting transplant candidates. Many years of technical and clinical refinements in lung transplantation methods have improved survival and quality of life outcomes. Further advances will probably come from improved selection methods for the procedure. Because no prospective trial has been performed, and because of confounding and informative censoring bias inherent in the transplant selection process in studies of the existing experience, the survival effect of lung transplant in COPD patients remains undefined. There is a lack of conclusive data on the impact of lung transplantation on quality of life. For some patients with end-stage COPD, lung transplantation remains the only option for further treatment with a hope of improved survival and quality of life. A prospective trial of lung transplantation is needed to provide better guidance concerning survival benefit, resource utilization, and quality of life effects for patients with COPD.","PeriodicalId":41597,"journal":{"name":"Transplant Research and Risk Management","volume":"54 1","pages":"1-20"},"PeriodicalIF":0.9,"publicationDate":"2013-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/TRRM.S10765","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68494343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, there is no consensus guideline as to the type or degree of donor steatosis considered acceptable for liver transplantation (LT), and little is known about local practices in this area. The aim of this survey was to evaluate current clinical practices amongst liver transplant surgeons in Australia and New Zealand (ANZ) in the evaluation and use of steatotic donor livers in LT. Methods: An anonymous online twelve-question survey was emailed to all practicing LT surgeons in ANZ (n = 23) in January 2010. Results: The response rate was 83%. Estimated prevalence of steatosis in donor livers was between 40% and 60%. In determining suitability for LT, 90% of respondents reported rejecting organs with “severe” steatosis based on visual and palpation grounds alone. A total of 68% sought further histological assessment if the donor liver looked bad and there were risk factors for steatosis. The majority of respondents performed only one biopsy of the liver (79%), using hematoxylin and eosin staining for fat assessment (53%). There was wide variation in the upper limit of steatosis considered to be acceptable for LT (40%–80% steatosis). A total of 21% of respondents still considered microvesicular steatosis a risk factor for primary graft nonfunction. Conclusion: This survey highlights the significant variation in the appraisal and use of steatotic grafts by LT surgeons in ANZ. Accurate evaluation and judicious use of mild and moderately steatotic grafts is required if we are to utilize the available donor pool best.","PeriodicalId":41597,"journal":{"name":"Transplant Research and Risk Management","volume":"4 1","pages":"31-37"},"PeriodicalIF":0.9,"publicationDate":"2012-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2147/TRRM.S33407","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68494997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our objective was to examine management of mineral metabolism in patients wait-listed for renal transplant and to determine the impact on cardiac perfusion imaging. Methods: Data was collected retrospectively on patients wait-listed for a renal transplant (n = 105), being either active (n = 73) or on hold (n = 32). Demographic data, medications, serum concentrations of calcium, phosphate, parathyroid hormone, and cardiac perfusion imaging studies were collected from the electronic health record. Chi-square and Student’s t-tests were used to compare active and on-hold patients as appropriate. Logistic regression was used to examine variables associated with worsening cardiac imaging studies. Results: The wait-listed patients were of mean age 56 ± 14 years and had been on dialysis for 1329 ± 867 days. On-hold patients had received a significantly greater total dose of calcium (2.35 ± .94 kg versus 1.49 ± 1.52 kg; P = 0.02) and were more likely to have developed worsening cardiovascular imaging studies (P = 0.03). Total doses of calcium and calcitriol were associated with worsening cardiovascular imaging studies (P = 0.05). Conclusion: Patients on hold on the renal transplant waiting list received higher total doses of calcium. A higher total dose of calcium and calcitriol was also associated with worsening cardiovascular imaging. Time on dialysis before transplant has been associated with worse post-transplant outcomes, and it is possible that the total calcium and calcitriol dose received contributed to these inferior outcomes.","PeriodicalId":41597,"journal":{"name":"Transplant Research and Risk Management","volume":"4 1","pages":"25-30"},"PeriodicalIF":0.9,"publicationDate":"2012-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68495136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
