Transplant tolerance has been achieved in experimental models using immune intervention strategies. Yet, their clinical translation remains unsuccessful and requires further optimization of immunotherapeutic regimens based on a deeper understanding of the cellular and molecular mechanisms at play in the induction and maintenance phases of immune tolerance. Intensive investigations have shed light on the tolerogenic networks underlying graft survival and have unraveled their complexity, which may depend on several p [...]

Islet transplantation is becoming an established treatment option for managing a subset of adult patients who have type 1 diabetes mellitus. The success of this procedure is dependent upon the recovery of a sufficient number of functional human islets from donor organs for subsequent transplant. Here, the use of optimized bacterial collagenase-neutral protease enzyme mixtures has been shown to affect the yield and quality (defined by viability and glucose-stimulated insulin secretion) of islets recovered from human [...]

Liver transplantation is a life-saving procedure available worldwide. Despite advances in its surgical and immunosuppressive strategies, infectious complications carry significant morbidity and mortality. Bacterial infections are the most common infective etiologies, and the majority are seen during the first four weeks post liver transplantation. Infectious complications are often intra-abdominal in origin, such as biliary complications and abdominal abscesses. Infections due to multi-drug resistant organisms are [...]

Background: Hematopoietic cell transplant (HCT) patients are a high-risk population for poor nutrition and decreased survival. There is little data on how nutrition in pediatric HCT patients affects need for critical care interventions and outcomes. Methods: We hypothesized that patients who did not meet goal nutrition by 72 hours post-admission to the pediatric intensive care unit (PICU) had increased in-hospital mortality and increased need for critical care interventions. We performed a retrospective cohort stud [...]

Even though renal ectopia is common, there have been very few reports of these kidneys being used for transplantation. The concerns with using such kidneys are subnormal function, ureteral anomalies and complications and anomalous arterial supply which makes arterial reconstruction challenging. Majority of reports are for use in living donor transplantation where good preoperative imaging is available. There is very scant literature reporting use of ectopic pelvic kidneys from deceased donors. We report a case of a [...]

Background: Human pancreatic islet transplantation is a minimally-invasive procedure that is gaining recognition for the treatment of type 1 diabetes (T1D). Selected patients with unstable T1D, hypoglycemia unawareness, history of severe hypoglycemia, and glycemic lability, not successfully stabilized with intensive insulin treatment, can be offered this alternative therapy that has been shown to provide long-term glycemic control with near-normalization of hemoglobin A1c in the absence of severe hypoglycemia. Toda [...]

Background: Human Papilloma virus (HPV) infections are an increasingly concerning etiology for post-transplantation viral-related malignancies. The nonavalent HPV vaccine (Gardasil 9) affords transplant recipients the best opportunity for malignancy prevention, but vaccine uptake remains low. Not previously reported for solid organ transplant recipients, we studied influential factors for HPV vaccine non-initiation. Methods: This survey, conducted from May to December 2017, examined influential factors for HPV vacc [...]

Background: Transplantation of isolated islets is one of the most powerful approaches to cure insulin-dependent (type I) diabetes mellitus (IDDM). Currently, the most widely used transplantation strategy is percutaneous perfusion into the liver via the portal vein. However, this approach has several drawbacks and is often limited by the large number of islets required and hypoxic damage to the grafts. Methods: In this article, we posit intrapancreatic parenchymal cell transplantation (IPPCT) as a promisin [...]
