Cover story:Differences in interpretation of how human islets isolated for allogeneic transplantation are to be categorized have allowed European and international clinical islet transplantation programs to flourish while programs in the US face more stringent regulations that have all but extinguished the hopes of diabetic patients to undergo the life-altering procedure.

The Future of Clinical Islet Transplantation in the United StatesAbstract Clinical islet transplantation was first realized over four decades ago at the University of Minnesota. Autologous islet transplantation is now widely recognized as a treatment to prevent diabetes in patients after pancreas excision and is offered at major transplant centers throughout the United States and the world. Type 1 diabetes represents a much larger demographic in which islet transplantation may benefit patients. Allogeneic islet transplantation can now offer similar outcomes to pancrea [...] |
Acute Graft-Versus-Host Disease, Prophylaxis and Therapyby

Abstract Graft-versus host disease is one of the major causes of death in patients undergoing allogeneic hematopoietic stem cell transplantation. Major contributing factors to severity of graft-versus host disease include HLA mismatch, conditioning regimen intensity, age of donor and recipient, source of stem cell, and donor type. Strategies and clinical trials are ongoing to reduce the incidence of graft-versus host disease, and to improve on the survival outcome of patients with graft-versus host disea [...] |

Abstract One of the most feared complications in liver transplantation is hepatic arterial thrombosis (HAT). The incidence of HAT in liver transplantation varies from 1.2% and 8%. One of the risk factors for this complication is anatomical complexity of hepatic arterial system. The focus of this short communication is to show our approach in dealing with aberrant left hepatic artery in settings of liver transplantation. This is a single center experience. Between January 2016 and June 2019, we procured a [...] |
Improved Awareness of Tuberculosis Infection in Advanced Stage Chronic Renal Disease Could Reduce Cases of Active TB: Lessons from Four Challenging CasesAbstract Patients with chronic kidney disease (CKD) have an increased risk of developing tuberculosis (TB) compared to those with normal renal function. The reasons for this are well described, but include impaired cellular immunity, a high incidence of co-morbid conditions as well as the concomitant use of immunosuppressive medications. Ethnicity as well as socio-economic factors also prevail. Expert guidelines recommend TB chemoprophylaxis in renal transplant recipients deemed at high risk – invariably [...] |

Abstract Allogeneic stem cell transplantation remains the only curative option for many hematological malignancies. Umbilical cord blood (UCB) is an alternate donor source with potentially increased morbidity in elderly patients. We evaluated outcomes in alternate donor sources, prior to the initiation of haploidentical transplantation at our institution, of matched unrelated donor (MUD) and UCB in elderly patients (mean age 64, range 60-75). One hundred and eighty-four patients were included (MRD: 57; M [...] |
Malignancies and Pediatric Liver Transplantation: Promising Management with the mTOR-inhibitor EverolimusAbstract Some malignancies such as hepatoblastoma may be an indication for liver transplantation (LT) or some, for example, post-transplant lymphoproliferative disease (PTLD) may develop after successful LT. An immunosuppressive therapy after LT can promote the recurrence of the primary malignancy. The mammalian target-of-rapamycin inhibitors (mTORi) are immunosuppressive agents with anti-tumor properties. We examined the impact of everolimus (EVL) together with calcineurin inhibitors on allograft outcom [...] |

Abstract Since 2018 The American Society of Transplant has recommended that Hepatitis C Virus seropositive positive, non-viremic donors (HCVAb+/NAT-) be considered non-infectious and safe for transplantation. This report describes clinical outcomes and HCV serological and virological outcomes following lung transplantation (LTx) utilizing such donors. This retrospective cohort study describes seven HCVAb+/NAT- donors used for bilateral LTx. Donor information was sourced from the national organ donation s [...] |
The Puzzle of Immunosuppressive DrugsAbstract Kidney transplantation has become the preferred treatment option in end-stage chronic renal failure as it provides significant improvements over dialysis in terms of both quality and duration of life. Even after several randomized studies conducted in the last 20 years, the combination of CNI, MMF, and steroids continues to be considered the gold standard for kidney transplantation. However, novel molecules aimed at minimizing renal and cardiovascular toxicity, particularly with CNI sparing, are [...] |

Pediatric Thoracoscopic Repair of Diaphragmatic Herniation Following Liver TransplantationAbstract Diaphragmatic Hernia (DH) after Liver Transplantation (LT) is a rare complication with unclear pathophysiology. Among 261 LT, we recognized six DH during the post transplant period (2.30%). All patients with DH had received a left lateral segment (LLS) reduced graft. The mean graft weight was 340g with a mean graft-to-recipient body weight ratio (GBWR) of 4.20%. LLS grafts, a GBWR > 4%, previous abdominal surgery and direct trauma during surgery can be enumerated as potential risk factors for [...] |
Management of the Sensitized Cardiac Transplantation RecipientAbstract Preoperative sensitization of the cardiac transplant recipient, defined as the presence of anti-Human Leukocyte Antigen (HLA) antibodies before transplant, represents a significant management challenge for physicians. Sensitization prolongs the pre-transplant wait time and is associated with postoperative transplant complications and death. It is critical that sensitized heart transplant candidates be identified and optimized before surgery. In this review, we describe the risk for sensitization [...] |
