BACKGROUND: Extracorporeal membrane oxygenation is a resource-intensive mode of life-support potentially applicable when conventional therapies fail. Given the initial success of extracorporeal membrane oxygenation to support neonates and infants in the 1980s, indications have expanded to include adolescents, adults, and selected moribund patients during cardiopulmonary resuscitation. This single-institution analysis was conducted to evaluate programmatic growth, outcomes, and risk for death despite extracorporeal membrane oxygenation across all ages and diseases...

Fresh osteochondral allografts are a well-established treatment for large, full-thickness cartilage defects. The clinical outcome for carefully selected patients is very favorable, especially for the young and active and graft survival up to 25 years has been described in the literature. Furthermore, a high patient satisfaction rate has been reported, but the biggest obstacle to overcome is the availability of tissue for transplantation. Large fresh bone allografts for cartilage damage repair only can be harvested from organ donors following organ removal or cadaveric donors, preferably in the setting of an operation room to minimize possible contamination of the tissue...

BACKGROUND: Although development of food allergy after liver transplantation is most commonly described in young children, little is known about identification of young liver-transplant recipients who are at risk of food allergy. OBJECTIVE: This study aimed to identify the types of food allergy and the risk factors for the development of food allergy after liver transplantation. METHODS: This was a retrospective analysis of pediatric liver transplant recipients in our organ transplantation center during 2005-2015...

BACKGROUND: Transplant vasculopathy limits the clinical results of solid organ transplantation. MATERIALS AND METHODS: Thirty-three arterial grafts were implanted in the abdominal aorta of Lewis rats. The animals were humanely sacrificed 4 wk after surgery. The study groups had 15 arterial isografts and 18 arterial allografts. Growth factors and inflammatory cytokines, released by the removed grafts, were studied in organ culture. The released growth factors were analyzed in vitro to assess their effect on the proliferation of endothelial, smooth muscle cells and fibroblasts...

Allogeneic hematopoietic cell transplantation (HCT) is an important treatment for many severe hematological disorders. However HCT can be associated with significant complications including organ toxicity, graft -versus-host disease and relapse. One other serious but rare complication is the transmission of hematologic and non- hematologic diseases from the donor to the recipient. With older donors, the risk of an abnormality in the donor may be higher. Here we describe the transmission of an inversion 3 constitutional cytogenetic abnormality from an unrelated donor to a recipient and review the clinical implications of the discovery of donor-derived constitutional cytogenetic abnormalities...

Cystic fibrosis (CF) affects multiple organs including the lung, liver, and pancreas. Lung transplant, liver transplant, and combined lung-liver transplant have become well-established therapies for CF patients with end-stage organ failure. Thus far, however, there has been limited experience with pancreas transplantation in CF. In this report, we detail the clinical history, transplant procedure, and post-operative recovery of a patient who underwent combined lung-liver-pancreas transplant for advanced CF.

Requests of organs to be transplanted increase. As a matter of urgency, it is not always easy to decide if a patient carrier of a brain tumor can be candidate in the donation. After a review of the literature, the members of the Association of the Neuro-oncologists of French Expression (ANOCEF) and the Club of Neuro-oncology of the French Society of Neurosurgery propose consensual recommendations in case of donor carrier of primitive tumor intra-cranial or intra-medullary. A contact with the neuro-oncologist/neurosurgeon will allow to discuss the indication in case of glioma of grade I/II/III, according to the grade, the current status (absence of progressive disease), the number of surgeries and of lines of treatment...

1. Everolimus is an inhibitor of mammalian target of rapamycin (mTOR) and has been clinically utilized to prevent the rejection of organ transplants. This study aims to determine the inhibition of everolimus on the activity of phase II drug-metabolizing enzymes UDP-glucuronosyltransferases (UGTs). 2. The results showed that 100 uM of everolimus exerted more than 80% inhibition towards UGT1A1, -1A3, and -2B7. UGT1A3 and UGT2B7 were selected to elucidate the inhibition mechanism, and in silico docking showed that hydrogen bonds and hydrophobic interactions mainly contributed to the strong binding of everolimus towards the activity cavity of UGT1A3 and UGT2B7...

Graft-versus-host disease (GvHD) is a major complication of allogeneic stem cell transplantation. High-resolution in vivo histology of the intestine by confocal endomicroscopy (CEM) detects acute GvHD (aGvHD) with high sensitivity. This pilot study aims to evaluate the diagnostic value of CEM for intestinal chronic GvHD (cGvHD). The study included 20 patients with gastrointestinal symptoms and confirmed cGvHD in other organs as well as 20 patients with clinically suspected acute GvHD for control. Confocal endomicroscopy was performed as gastroscopy followed by sigmoidoscopy after intravenous injection of fluorescein (10%) and topical application of acriflavine (0...

Organ transplants give a second chance of life to patients with end-stage organ failure. However, the immuno-logical barriers prove to be very challenging to overcome and graft rejection remains a major hurdle to long-term transplant survival. For decades, adaptive immunity has been the focus of studies, primarily based on the belief that T cells are necessary and sufficient for rejection. With better-developed immunosuppressive drugs and protocols that effectively control adaptive cells, innate immune cells have emerged as key effector cells in triggering graft injury and have therefore attracted much recent attention...

Activated T cells have been shown to be able to recirculate into the thymus from the periphery. The present study was aimed to elucidate the functional consequences of thymic homing of activated T cells upon developing thymocytes and thymic epithelial cells (TEC). In the presence of activated T cells, especially CD4(+) T cells, T cell development was found to be inhibited in thymic organ cultures with markedly reduced cellularity. Thymic transplantation demonstrated that the inhibitory effect was most likely due to a defective microenvironment...

BACKGROUND AND OBJECTIVES: Use of diabetic donor kidneys has been a necessary response to the donor organ shortage. Recipients of diabetic donor kidneys have higher mortality risk compared with recipients of nondiabetic donor kidneys. However, the survival benefit of transplantation with diabetic donor kidneys over remaining on the waitlist has not been previously evaluated. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We performed an observational cohort study of 437,619 kidney transplant candidates from the Organ Procurement and Transplantation Network database, including 8101 recipients of diabetic donor kidneys and 126,560 recipients of nondiabetic donor kidneys...

Pediatric lung transplant is a viable option for treatment of end-stage lung disease in children, with > 100 pediatric lung transplants reported to the Registry of the International Society of Heart and Lung Transplantation each year. Long-term success is limited by availability of donor organs, debilitation as a result of chronic disease, impaired mucus clearance resulting from both surgical and pharmacologic interventions, increased risk for infection resulting from immunosuppression, and most importantly late complications, such as chronic lung allograft dysfunction...

This article reviews the common pulmonary complications seen in the pediatric oncology population and our approach to diagnosis, management, and therapy considerations in this specialized population, including patients receiving chemotherapy, radiation, and hematopoietic stem cell transplantation. Although infections cause the most significant complications in this population, non-infectious complications, including acute lung injury from chemotherapy or radiation, idiopathic interstitial pneumonia, diffuse alveolar hemorrhage, bronchiolitis obliterans, and cryptogenic organizing pneumonia, also occur commonly...

Light chain amyloidosis (AL) results in tissue deposition of misfolded proteins causing organ dysfunction. In an era of modern therapies such as bortezomib, reassessment of the benefit of autologous hematopoietic cell transplantation (AHCT) should be considered. This study compares the difference in outcomes between patients with AL receiving chemotherapy alone (CT) vs. AHCT. Seventy-four patients with AL were retrospectively analyzed. Two cohorts of patients were studied, those receiving CT (n=31) or AHCT (n=43)...

Hepatitis B is one of the most common infectious diseases globally. It has been estimated that there are 350 million chronic hepatitis B virus (HBV) carriers worldwide. The liver is connected to the small intestine by the bile duct, which carries bile formed in the liver to the intestine. Nearly all of the blood that leaves the stomach and intestines must pass through the liver. Human intestines contain a wide diversity of microbes, collectively termed the 'gut microbiota'. Gut microbiota play a significant role in host metabolic processes and host immune modulation, and influence host development and physiology (organ development)...

OBJECTIVE: Create an efficient decision-support model to assist medical experts in the process of organ allocation in liver transplantation. The mathematical model proposed here uses different sources of information to predict the probability of organ survival at different thresholds for each donor-recipient pair considered. Currently, this decision is mainly based on the Model for End-stage Liver Disease, which depends only on the severity of the recipient and obviates donor-recipient compatibility...

T cell depletion is widely used as induction therapy in solid organ transplants and particularly in kidney transplantation, to reduce the episodes of acute cellular rejection. The resultant reduction in T cell numbers is usually temporary, as T cells are actively replenished due to thymic output and/or lymphopenia-induced proliferation of remaining, depletion-resistant T cells. However, the extent of T cell replenishment and the persistence of lymphopenia varies between individuals, with potential impacts on protective or pathogenic immune responses...

Breast cancer is an important cancer among solid organ transplant recipients. While the incidence of breast cancer in solid organ transplant recipients is comparable to the age matched general population, the outcomes are generally poor. Interventions such as cancer screening which preclude the development of late stage disease through early detection are not well-studied, and clinical practice guidelines for cancer screening rely solely on recommendations from the general population. Among those with a prior breast cancer history, disease recurrence after transplantation is a rare but fearful event...

Rates of multi-drug resistant organisms (MDRO) colonization among intestinal transplant (ITx) recipients have not been reported. Colonization rates with vancomycin-resistant Enterococcus (VRE), carbapenem-resistant gram-negative bacteria (CR-GNB) and methicillin-resistant Staphylococcus aureus (MRSA) were obtained retrospectively in adults undergoing ITx (isolated or multi-visceral) from 1/2009-12/2015. We assessed for VRE, CR-GNB and MRSA bacteremia during the first year post-transplant for patients colonized with VRE, CR-GNB and MRSA respectively and for those who were not colonized...
