Abstract
Natural killer T cells (NKTs) are innate-like lymphocytes that are abundant in the liver and participate in liver immunity. NKT cells express both NK cell and T cell markers, modulate innate and adaptive immune responses. Type I and Type II NKT cells are classified according to the TCR usage, while they recognize lipid antigen in a non-classical major histocompatibility (MHC) molecule CD1d-restricted manner. Once activated, NKT cells can quickly produce cytokines and chemokines to negatively or positively regulate the immune responses, depending on the different NKT subsets. In liver transplantation (LTx), the immune reactions in a series of processes determine the recipients' long-term survival, including ischemia-reperfusion injury, alloresponse, and post-transplant infection. This review provides insight into the research on NKT cells subpopulations in LTx immunity during different processes, and discusses the shortcomings of the current research on NKT cells. Additionally, the CD56-expressing T cells are recognized as a NK-like T cell population, they were also discussed during these processes.

Abstract
Advancements in immunosuppression protocols, surgical techniques, and postoperative care in the last few decades have improved outcomes of intestinal transplant patients. Normal immediate postoperative imaging appearance can simulate pathology. Intestinal transplant recipients are prone for several postoperative complications due to the complex surgical technique, which involves multiple anastomoses, and immunogenic nature of the allograft intestine. Imaging plays a crucial role in detection of several major complications including infectious, immunologic, vascular, gastrointestinal, pancreaticobiliary, genitourinary, and neoplastic complications. The awareness of the posttransplant anatomy and normal imaging appearances helps radiologists anticipate and accurately detect posttransplant complications.

Abstract
PURPOSE OF REVIEW The role of intestinal transplant has expanded in recent years and is no longer only considered for patients with no other options remaining. 5 year survival in high-volume centres is over 80% for certain graft types. The aim of this review is to update the audience on the current state of intestinal transplant, with a focus on recent medical and surgical advances. RECENT FINDINGS There has been a greater understanding of the interplay and balance of host and graft immune responses, which may facilitate individualized immunosuppression. Some centres are now performing 'no-stoma' transplants, with preliminary data showing no adverse effects from this strategy and other surgical advances have lessened the physiological insult of the transplant operation. Earlier referrals are encouraged by transplant centres, such that vascular access or liver disease has not progressed too much to increase the technical and physiological challenge of the procedure. SUMMARY Clinicians should consider intestinal transplant as a viable option for patients with intestinal failure, benign unresectable abdominal tumours or acute abdominal catastrophes.

Abstract
Pediatric intestinal transplant serves as the only definitive treatment for children with irreversible intestinal failure. Successful intestinal transplant hinges upon appropriate management of immunosuppression. The indications for intestinal transplant have changed over time. Immunosuppression regimens can be divided into induction and maintenance phases along with treatment of acute rejection. Intestinal transplant induction now often includes antithymocyte globulin or basiliximab in addition to corticosteroids. Maintenance regimens continue to be dominated by tacrolimus, with additional agents used to either decrease goal tacrolimus levels to limit toxicity or as an adjunct in sensitized patients. Careful monitoring can help to limit serious complications, such as rejection, infection, and malignancy. Future work will aim to decrease variation in practice and identify methods to determine optimal immunosuppression for a particular patient. Furthermore, there is a need for non-invasive monitoring of the intestinal graft and functional assessments of immunosuppression.

Abstract
De novo HCC following transplantation in a child is a rare occurrence. Even within the adult liver transplantation population, there are a limited number of published cases. In this report, we present a case of de novo HCC found in a child, post-multivisceral transplantation. A 19-year-old boy, at the age of one, received liver and small bowel transplantation due to short gut syndrome secondary to midgut volvulus and total parenteral nutrition-associated liver disease. Eighteen years later, he was found to have a large mass involving the right hepatic dome consistent with HCC. To the best of our knowledge, this is the second reported case after gut transplantation and the third case post-liver transplantation in the pediatric population.

Abstract
PURPOSE OF REVIEW In this article, data from the intestinal transplant registry, recent publications and reviews in the field will be used to describe mortality, morbidity, complications, nutritional and psychosocial outcomes in intestinal transplant recipients with a focus on those furthest out from transplant. RECENT FINDINGS Registry data show static long-term survival data (41% 10-year survival in the most recent analysis), but experienced centres report improvements with survival between 60 and 70% at 10 years. Chronic rejection remains a problem for long-term graft survival, but understanding of humoral immunity is increasing. Nutritional outcomes are good with most recipients achieving enteral autonomy with an unrestricted diet. Health-related quality of life data generally shows improvement in the years after transplant, educational attainment is good, but some patients have ongoing psychosocial problems. SUMMARY Most patients do well in the long-term after transplant. Survival outcomes have improved in experienced centres, and nutrition and quality of life outcomes are good. Recognition of psychosocial outcomes is increasing. Nevertheless, challenges remain in areas such as infectious complications, renal function, chronic rejection, social support and mental health.

Abstract
PURPOSE OF REVIEW The present review aims to describe in detail the characteristics, outcomes, and recent trends in the field of pediatric intestinal transplantation in the United States. It will examine the route cause and future implications of these developments. The review will draw from recent publications in the field, the Intestinal Transplant Registry, and contemporary data from large U.S. single centers. RECENT FINDINGS More than 1500 pediatric intestinal transplants have been performed in the United States since 1985, however, over the past decade there have been fewer than 50 transplants/year nationwide. This trend is largely a result of stagnant long-term ITx outcomes and advancements in intestinal rehabilitation programs. Nationally the overall 1-year and 5-year graft survival are 68 and 50% respectively, whereas certain high-volume centers have experienced significantly better results. Sepsis is the leading cause of death following pediatric ITx, whereas rejection is the leading cause of graft loss. Chronic kidney disease and posttransplant lymphoproliferative disorder are significant and relatively prevalent long-term complications. The majority of pediatric ITx recipients receive T-cell depleting induction agents and are on Tacrolimus-based immunosuppression. Most recipient are off parenteral nutrition, but may require supplemental tube feeds. Many pediatric ITx recipients require special education, and in certain domains some report lower health related quality of life. SUMMARY As intestinal rehabilitation has improved in the modern era, the volume of pediatric ITx in the United States has decreased. Although pediatric ITx results have room for improvement nationwide, successful outcomes have been reported at experienced American centers.

Abstract
Pediatric recipients of intestinal transplants have a high incidence of PTLD, but the impact of specific induction immunosuppression agents is unclear. In this single-center retrospective review from 2000 to 2017, we describe the incidence, characteristics, and outcomes of PTLD after primary intestinal transplantation in 173 children with or without liver, after induction with rATG, alemtuzumab, or anti-IL-2R agents. Thirty cases of PTLD occurred among 28 children, 28 EBV+ and 2 EBV-. Although not statistically significant, the PTLD incidence was higher after isolated intestinal transplant compared with liver-inclusive allograft (19.3% vs 13.3%, P = .393) and after induction with anti-IL-2R antibody and alemtuzumab compared with rATG (28.6% and 27.3% vs 13.3%, P = .076). The 30 PTLD cases included 13 monomorphic PTLD, 13 polymorphic PTLD, one spindle cell, one Burkitt lymphoma, and two cases too necrotic to classify. After reduction of immunosuppression, management was based on disease histology and extent. Resection with or without rituximab was used for polymorphic tumors and limited disease extent, whereas chemotherapy was used for diffuse disease. Of the 28 patients, 11 recovered with functioning allografts (39.3%), 10 recovered after enterectomy (35.7%), and seven patients died (25%), three due to PTLD and four due to other causes. All who died of progressive PTLD had received chemotherapy, highlighting the mortality of PTLD, toxicity of treatment and need for novel agents. Alemtuzumab is no longer used for induction at our center.

Abstract
BACKGROUND Post-transplant malignancies, that is, lymphomas, are a recognized complication in intestinal transplant recipients but are mostly secondary to EBV infection. There is an increased risk for malignancies in unusual sites in intestinal transplant recipients as compared to other solid organ transplants and the general population. OBJECTIVE To evaluate the incidence, course, and outcome of unusual malignancies in children after ITx. METHODS Retrospective analysis of children who underwent ITx for primary digestive disorders at Birmingham Children's Hospital between January 1989 and December 2017. RESULTS Ninety-eight intestinal transplants were performed in 90 children (49 males and 41 females) with an underlying primary digestive disorder. Median age was 2.7 years (0.6-16.2), and median weight was 14.5 kg (5.7-53.2) at the time of transplant. Within this cohort, we identified four cases of unusual malignancies at rare sites of presentation. One patient developed cerebral PTLD, two patients were diagnosed with SMT, located at the stomal orifice and in cervicothoracic paravertebral area, respectively, and the last patient developed a retroperitoneal angiosarcoma. Unfortunately, the overall patient outcome was poor in all but one child with SMT, who currently survives with cytotoxic T-cell therapy. CONCLUSION Unusual malignancies can occur in approximately 5% of children following ITx. A high index of suspicion is required for a timely diagnosis and adequate treatment.

Abstract
Background Standardized and sensitive assays for Epstein Barr Virus (EBV) are needed to define universal cutoff for treatment initiation in allogeneic hematopoietic stem cells transplant recipients. In a context of accreditation and the availability of EBV international standard, we evaluated the Abbott RealTime EBV (RT) assay for EBV quantification in whole blood. Methods The RT assay was compared on 282 prospective clinical samples with the Artus EBV PCR Kit V1 assay (V1) and we analyzed the kinetics of EBV load in 11 patients receiving rituximab treatment. Results The estimated limit of detection was 88 IU/mL. The assay was linear (r2 = 0.9974) in the range of all samples tested (100 to 1,000,000 IU/mL). Intra-assay coefficients of variation (CV) ranged between 0.35 and 1.35%, and inter-assay CV between 3.40 and 4.5%. On samples above the limit of quantification, the two assays were strongly correlated. EBV RT values were on average 0.30 log10 IU/mL lower than those measured with the V1 assay. In patients treated with rituximab, the RT assay remained positive in 5 patients at the time it dropped below undetectable levels with the V1 assay. Conclusions In conclusion, the RT assay is a reliable assay for EBV load in whole blood. Its sensitivity will enable to estimate the kinetics of EBV load and the impact of treatments to control EBV reactivations.

Abstract
Survival following liver transplantation has changed dramatically owing to improvement in surgical techniques, peri-operative care and optimal immunosuppressive therapy. Post-Liver transplant (LT) de novo or recurrent viral infection continues to cause major allograft dysfunction, leading to poor graft and patient survival in untreated patients. Availability of highly effective antiviral drugs has significantly improved post-LT survival. Patients transplanted for chronic hepatitis B infection should receive life-long nucleos(t)ide analogues, with or without HBIg for effective viral control. Patients with chronic hepatitis C should be commenced on directly acting antiviral (DAA) drugs prior to transplantation. DAA therapy for post-LT recurrent hepatitis C infection is associated with close to 100% sustained virological response (SVR), irrespective of genotype. De novo chronic Hepatitis E infection is an increasingly recognised cause of allograft dysfunction in LT recipients. Untreated chronic HEV infection of the graft may lead to liver fibrosis and allograft failure. CMV and EBV can reactivate leading to systemic illness following liver transplantation. With COVID-19 pandemic, post-transplant patients are at risk of SARS-Co-V2 infection. Majority of the LT recipients require hospitalization, and the mortality in this population is around 20%. Early recognition of allograft dysfunction and identification of viral aetiology is essential in the management of post-LT de novo or recurrent infections. Optimising immunosuppression is an important step in reducing the severity of allograft damage in the treatment of post-transplant viral infections. Viral clearance or control can be achieved by early initiation of high potency antiviral therapy.

Abstract
The successful development of multivisceral and composite visceral transplantation is among the milestones in the recent history of human organ transplantation. All types of gastrointestinal transplantation have evolved to be the standard of care for patients with gut failure and complex abdominal pathologic conditions. The outcome has markedly improved over the last 3 decades owing to technical innovation, novel immunosuppression, and better postoperative care. Recent data documented significant improvement in the long-term therapeutic indices of all types of visceral transplantation close to that achieved with thoracic and solid abdominal organs.

Abstract
Transplantation of the intestine in children has presented significant challenges even as it has become a standard to treat nutritional failure due to short gut syndrome. These challenges have been addressed in part by significant improvements in short and long-term care. Noteworthy enhancements include reduced need for intestine transplantation, drug-sparing immunosuppressive regimens, immune monitoring, and improved surveillance and management of PTLD and non-adherence.

Abstract
Intestinal transplantation is a successful treatment for children with intestinal failure, but has many potential complications. PTLD, a clinically and histologically diverse malignancy, occurs frequently after intestinal transplantation and can be fatal. The management of this disease is particularly challenging. The rejection-prone intestinal allograft requires high levels of immunosuppression, a precondition for PTLD. While EBV infection clearly plays a role in disease pathogenesis, the relatively naïve immune system of children is another likely contributor. As a result, pediatric intestine recipients have a higher risk of developing PTLD than other solid organ recipients. Other risk factors for disease development such as molecular and genomic changes that precipitate malignant transformation are not fully understood, especially among children. Studies on adults have started to describe the molecular pathogenesis of PTLD, but the genomic landscape of the malignancy remains largely undefined in pediatric intestinal transplant patients. In this review, we describe what is known about PTLD in pediatric patients after intestinal transplant and highlight current knowledge gaps to better direct future investigations in the pediatric population.

Abstract
The successful development of multivisceral and composite visceral transplantation is among the milestones in the recent history of human organ transplantation. All types of gastrointestinal transplantation have evolved to be the standard of care for patients with gut failure and complex abdominal pathologic conditions. The outcome has markedly improved over the last 3 decades owing to technical innovation, novel immunosuppression, and better postoperative care. Recent data documented significant improvement in the long-term therapeutic indices of all types of visceral transplantation close to that achieved with thoracic and solid abdominal organs.

Abstract
Pediatric intestinal transplantation has moved from the theoretic to an actual therapy for children with irreversible intestinal failure who are suffering from complications of total parenteral nutrition. Owing to significant advancement in the management of intestinal failure and prevention of parenteral nutrition-related complications that have led to reduction in incidence of parenteral nutrition-associated liver disease and have improved intestinal adaptation, the indications for intestinal transplantation are evolving. Long-term outcomes have improved, but challenges in long-term graft function owing to chronic rejection and immunosuppressant-related complications remain the major opportunities for improvement.

Abstract
We report the first two cases of posttransplant lymphoproliferative disorder (PTLD) in recipients of islet transplants worldwide. First, a 44-year-old recipient of three islet infusions developed PTLD 80 months after his initial transplantation, presenting with abdominal pain and diffuse terminal ileum thickening on imaging. He was treated with surgical excision, reduction of immunosuppression, and rituximab. Seven months later, he developed central nervous system PTLD, presenting with vertigo and diplopia; immunosuppression was discontinued, resulting in graft loss, and he was given high-dose methotrexate and underwent consolidative autologous stem cell transplantation. He remains in remission 37 months after the initial diagnosis. Second, a 58-year-old female recipient of two islet infusions developed PTLD 24 months after initial islet infusion, presenting with pancytopenia secondary to extensive bone marrow involvement. Immunosuppression was discontinued, resulting in graft loss, and she received rituximab and chemotherapy, achieving complete remission. Both patients were monomorphic B cell PTLD subtype by histology and negative for Epstein-Barr virus in tissue or blood. These cases document the first occurrences of this rare complication in islet transplantation, likely secondary to prolonged, intensive immunosuppression, and highlight the varying clinical manifestations of PTLD. Further studies are needed to determine incidence rate and risk factors in islet transplantation.

Abstract
The field of intestinal transplantation has experienced dramatic growth since the first reported cases 3 decades ago. Improvements in operative technique, donor assessment and immunosuppressive protocols have afforded children who suffer from life-threatening complications of intestinal failure a chance at long-term survival. As experience has grown, newer diseases, with more systemic manifestations have arisen as potential indications for transplant. After discussing the historical developments of intestinal transplant as a backdrop, this review focuses on the specific pre-operative indications for transplant as well as the great success that intestinal rehabilitation has witnessed over the past decade. A detailed discussion of evolution of immunosuppressive strategies is followed a general review of the common infectious complications experienced by children after intestinal transplant as well as the current long- and short-term results, including a section on new research on the quality of life in this challenging population of patients.

Abstract
Prior to transplantation of hematopoietic stem cells or solid organ, donor and recipient EBV serostatus has to be determined to assess risks of post-transplant lymphoproliferative disorders. Sensitivity of EBV Viral capsid antigens (VCA) IgG and EBV nuclear antigen-1 (EBNA-1) is critical to define past infection and a good specificity of VCA IgM is required to avoid any disqualification of cord blood (CB) units. Architect™ EBV antibody panel (Architect assay) providing a high throughput was compared to a semi-automated ELISA (Etimax assays Diasorin) to assess sensitivities and specificities of VCA and EBNA-1 IgG and VCA IgM on 419 sera collected from immunocompromised patients (n = 184) and from pregnant women who agreed to give CB cells (n = 235). Intra and inter-assay coefficient of variations ranged from 1.63% to 4.8% for VCA IgM, VCA IgG, and EBNA-1 IgG. Index of VCA IgG and IgM and EBNA IgG of the two assays were highly correlated. The concordance in the interpretation between the two assays was moderate for VCA IgM (kappa = 0.5), substantial for VCA IgG (kappa = 0.60) and good for EBNA-1 IgG (kappa = 0.75). Using serial dilutions of positive controls and in accordance with clinical results VCA IgG and EBNA IgG were detected at lower dilutions with Architect than Etimax. Conversely, 96.1% (74/77) of samples negative with Architect and positive with Etimax for VCA IgM did not have any heterophile antibodies and had VCA IgG and EBNA IgG antibodies supporting past infections. Architect™ EBV serology panel provided good sensitivities and specificities for EBV serostatus determination prior to transplantation.

Abstract
PURPOSE OF REVIEW The purpose of this article is to review the existing literature on the current indications, surgical techniques, immunosuppressive therapy and outcomes following intestinal transplantation (ITx). RECENT FINDINGS Over recent years, ITx has become a more common operation with approximately 2500 procedures carried out worldwide by 2014. It is reserved for patients with intestinal failure and who have developed complications of home parenteral nutrition or who have a high risk of dying from their underlying disease. Recent advances such as the improvement in survival rates, not only for isolated small bowel transplants but also following inclusion of a liver graft in combined liver-small bowel transplant, and the utility of citrulline as a noninvasive biomarker to appreciate acute rejection herald an exciting shift in the field of ITx. SUMMARY With advancements in immunosuppressive drugs, induction regimens, standardization of surgical techniques and improved postoperative care, survival is increasing. In due course, it will most likely become as good as remaining on home parenteral nutrition and as such could become a viable first-line option.

Abstract
Clinical-nutritional autonomy is the ultimate goal of patients with intestinal failure (IF). Traditionally, patients with IF have been relegated to lifelong parenteral nutrition (PN) once surgical and medical rehabilitation attempts at intestinal adaptation have failed. Over the past two decades, however, outcome improvements in intestinal transplantation have added another dimension to the therapeutic armamentarium in the field of gut rehabilitation. This has become possible through relentless efforts in the standardization of surgical techniques, advancements in immunosuppressive therapies and induction protocols and improvement in postoperative patient care. Four types of intestinal transplants include isolated small bowel transplant, liver-small bowel transplant, multivisceral transplant and modified multivisceral transplant. Current guidelines restrict intestinal transplantation to patients who have had significant complications from PN including liver failure and repeated infections. From an experimental stage to the currently established therapeutic modality for patients with advanced IF, outcome improvements have also been possible due to the introduction of tacrolimus in the early 1990s. Studies have shown that intestinal transplant is cost-effective within 1-3 years of graft survival compared with PN. Improved survival and quality of life as well as resumption of an oral diet should enable intestinal transplantation to be an important option for patients with IF in addition to continued rehabilitation. Future research should focus on detecting biomarkers of early rejection, enhanced immunosuppression protocols, improved postoperative care and early referral to transplant centers.

Abstract
BACKGROUND Antibody-mediated rejection (ABMR) has recently surfaced as a potential form of graft dysfunction after intestinal transplantation. METHODS We present a case of an intestinal transplant recipient who developed late-onset ABMR 12 years after living-donor transplantation. An 18-year-old male recipient with a history of extensive intestinal resection secondary to acute bowel volvulus exhibited an excellent baseline immune profile for transplantation, including ABO-identical and HLA-haploidentical to the donor; a negative cross-match with a panel reactive antibody of 3.0%. RESULTS Post-transplantation immunosuppression consisted of tacrolimus, mycophenolate mofetil (MMF), and prednisone within the first year, followed by tacrolimus and MMF in the second year, and maintenance with tacrolimus monotherapy thereafter. The recipient experienced a single episode of indetermined acute cellular rejection 3 months after transplantation. Since then, he did not require any parenteral nutrition and had completely reintegrated with society. Twelve years later, the patient developed persistent diarrhea associated with transplant biopsy diffuse C4d deposition and circulating donor-specific antibodies. After the use of rituximab and intravenous immunoglobulin, the recipient stabilized 17 years after transplantation with complete recovery of intestinal mucosal damage. CONCLUSION Late-onset ABMR can emerge after transplantation and must be considered a possible cause of graft dysfunction in long-term intestinal transplantation survivors.

Abstract
BACKGROUND We report the case of a 7-year-old girl with intestinal failure owing to a cystic lymphangioma compromising the root of the mesentery, not amenable to resection, leading to intestinal failure. Oncologic treatment was attempted to reduce tumor size with no response; therefore, she was listed for multivisceral transplantation. PROCEDURE Resection of the tumor required resection of all abdominal organs with vascular inflow and outflow. A multivisceral graft (liver, stomach, duodenum-pancreas and spleen complex, small bowel, and right colon) was implanted. For vascular reconstruction, donor's superior vena cava was sutured to the recipient's suprahepatic veins in a common patch. For arterial inflow, an arterial conduit was placed directly to the infrarenal aorta, and sutured to an aortic patch of the graft. Cold ischemia time was 8:45 hours; warm ischemia time was 35 minutes. A double-layer gastrogastric anastomosis and piloroplasty was made; and the distal reconstruction was performed with ileocolic side-to-end anastomosis that allowed to perform of a Bishop-Koop ileostomy for endoscopic monitoring. OUTCOME The patient recovered well after the procedure and was discharged 36 days after transplantation with intestinal sufficiency. To the best of our knowledge, this is the first report describing cystic lymphangioma as an indication for multivisceral transplantation.

Abstract
In this study, we sought to determine the incidence of post-transplant complications including acute cellular rejection (ACR), infection, and post-transplant lymphoproliferative disease (PTLD) in mucosal allograft biopsies in patients with small bowel transplant at our institution. We retrospectively reviewed pathology reports from 5675 small bowel allograft biopsies from 99 patients and analyzed the following: indications for biopsy, frequency and grade of ACR, the presence of infectious agents, results of workup for potential PTLD, results of C4d immunohistochemistry (IHC), features of chronic mucosal injury, and findings in concurrent native bowel biopsies. Findings from 42 allograft resection specimens were also correlated with prior biopsy findings. Indeterminate, mild, moderate, and severe ACR were seen in 276 (4.9%), 409 (7.2%), 100 (1.8%), and 207 (3.6%) of biopsies, respectively. Although ACR may show histologic overlap with mycophenolate mofetil toxicity, we found the analysis of concurrent native bowel biopsies to be helpful in this distinction. Adenovirus was the most common infectious agent seen (11%), and we routinely performed adenovirus IHC on biopsies. Eighteen patients (18%) developed PTLD, 83% of which were EBV associated, but only 28% of PTLD cases were diagnosed on mucosal allograft biopsies. C4d IHC did not correlate with the presence of donor-specific antibodies in limited cases.

Abstract
Intestinal transplantation has become a well-accepted and successful procedure to save the lives of patients suffering from intestinal failure and who have developed life-threatening complications of parenteral nutrition. Advances in all aspects of care, from the role of multidisciplinary intestinal rehabilitation services prior to transplant to the development strategies for early recognition of infectious sequelae and even the increasing availability of preventive strategies, have led to improved outcomes and a dramatic decline in infection-associated morbidity and mortality in children undergoing intestinal transplantation. Improvements in surgical techniques and immunosuppressive regimens have been essential components in these improvements, reducing risk of infection through reduction of technical complications and more optimal immunosuppression regimens. In addition, the development of molecular tools for early recognition of viral pathogens and an understanding of the timing and risks for infection have allowed for earlier and more successful treatments. Despite these improvements, infectious sequelae remain an important problem in this population, and additional efforts are needed to further minimize the risk of infectious sequelae in those children requiring this procedure.

Abstract
The lack of a large animal transplantable tumor model has limited the study of novel therapeutic strategies for the treatment of liquid cancers. Swine as a species provide a natural option based on their similarities with humans and their already extensive use in biomedical research. Specifically, the Massachusetts General Hospital miniature swine herd retains unique genetic characteristics that facilitate the study of hematopoietic cell and solid organ transplantation. Spontaneously arising liquid cancers in these swine, specifically myeloid leukemias and B cell lymphomas, closely resemble human malignancies. The ability to establish aggressive tumor cell lines in vitro from these naturally occurring malignancies makes a transplantable tumor model a close reality. Here, we discuss our experience with myeloid and lymphoid tumors in major histocompatibility characterized miniature swine and future approaches regarding the development of a large animal transplantable tumor model.

Abstract
BACKGROUND Multivisceral transplantation represents an important treatment option for children with intestinal failure. The attendant immunosuppression can lead to a spectrum of cellular proliferations including benign and malignant smooth muscle tumors and lymphoproliferative disorders, many related to cellular dysregulation from Epstein-Barr virus infection. OBJECTIVE The purpose of this study is to investigate the rates of post-transplantation proliferative disorders among children with multivisceral transplantation and to characterize the imaging and pathological features of these disorders. MATERIALS AND METHODS We identified all consecutive children who underwent multivisceral transplant from August 2004 to October 2011 with at least 27 months of clinical and imaging follow-up. We reviewed medical records to determine the underlying causes of the multivisceral transplant, age at transplantation, onset of neoplasm development, and outcome. Two pediatric radiologists reviewed all imaging studies independently and diagnosis of disease was made by consensus interpretation. Pathological specimens were reviewed for histopathological findings of post-transplantation neoplasm in this pediatric patient population. RESULTS The study population consisted of 14 consecutive pediatric patients (7 boys and 7 girls; mean age 26 months, range 4-113 months). Of these 14 children, 4 (29%) developed histologically confirmed post-transplant neoplasms at a mean time of 2.4 years after multivisceral transplantation. Types of neoplasms included post-transplant lymphoproliferative disorder (PTLD) in three (21%) and Epstein-Barr-virus-associated smooth muscle tumor in two (14%). (One child developed both neoplasms following transplantation). Both children with smooth muscle tumor associated with Epstein-Barr virus presented with characteristic hypointense solid masses with peripheral rim enhancement on cross-sectional imaging studies. The mortality rate of children who developed post-transplant neoplasms was higher than that of those who did not develop post-transplant neoplasm (50% vs. 10%, P = 0.17), suggesting a possible risk factor for death. CONCLUSION Post-transplant neoplasm in children with multivisceral transplantation occurs with high frequency, often presents as Epstein-Barr-virus-associated smooth muscle tumor showing characteristic peripheral rim enhancement on cross-sectional imaging studies.

Abstract
In the 1990s, the introduction of visceral transplantation fuelled interest in other innovative therapeutic modalities for gut rehabilitation. Ethanol lock and omega-3 lipid formulations were introduced to reduce the risks associated with total parenteral nutrition (TPN). Autologous surgical reconstruction and bowel lengthening have been increasingly utilized for patients with complex abdominal pathology and short-bowel syndrome. Glucagon-like peptide 2 analogue, along with growth hormone, are available to enhance gut adaptation and achieve nutritional autonomy. Intestinal transplantation continues to be limited to a rescue therapy for patients with TPN failure. Nonetheless, survival outcomes have substantially improved with advances in surgical techniques, immunosuppressive strategies and postoperative management. Furthermore, both nutritional autonomy and quality of life can be restored for more than two decades in most survivors, with social support and inclusion of the liver being favourable predictors of long-term outcome. One of the current challenges is the discovery of biomarkers to diagnose early rejection and further improve liver-free allograft survival. Currently, chronic rejection with persistence of preformed and development of de novo donor-specific antibodies is a major barrier to long-term graft function; this issue might be overcome with innovative immunological and tolerogenic strategies. This Review discusses advances in the field of gut rehabilitation, including intestinal transplantation, and highlights future challenges. With the growing interest in individualized medicine and the value of health care, a novel management algorithm is proposed to optimize patient care through an integrated multidisciplinary team approach.

Abstract
Intestine transplantation is the least common form of organ transplantation in the United States and often deemed one of the most difficult. Patient and graft survival have historically trailed well behind other organ transplants. Over the past 5-10 years registry reports and single center series have demonstrated improvements to patient survival after intestinal transplantation that now match patient survival for those without life-threatening complications on parenteral nutrition. For various reasons including improvements in medical care of patients with intestinal failure and difficulty accessing transplant care, the actual number of intestine transplants has declined by 25% over the past 6 years. In light of the small numbers of intestine transplants, many physicians and the lay public are often unaware that this is a therapeutic option. The aim of this review is to describe the current indications, outcomes and advances in the field of intestine transplantation and to explore concerns over future access to this important and life-saving therapy.

Abstract
BACKGROUND Small bowel transplantation evolution, because of its complexity, was slower than other solid organs. Several advances have enabled its clinical application. AIM To review intestinal transplantation evolution and its current status. METHOD Search in MEDLINE and ScIELO literature. The terms used as descriptors were: intestinal failure, intestinal transplantation, small bowel transplantation, multivisceral transplantation. Were analyzed data on historical evolution, centers experience, indications, types of grafts, selection and organ procurement, postoperative management, complications and results. CONCLUSION Despite a slower evolution, intestinal transplantation is currently the standard therapy for patients with intestinal failure and life-threatening parenteral nutrition complications. It involves some modalities: small bowel transplantation, liver-intestinal transplantation, multivisceral transplantation and modified multivisceral transplantation. Currently, survival rate is similar to other solid organs. Most of the patients become free of parenteral nutrition.

Abstract
Intestinal transplantation is the definitive therapy for patients with irreversible intestinal failure and can be combined with transplantation of other abdominal organs, such as stomach, spleen, and pancreas with or without liver. There is an increasing trend in the volume of intestinal and multivisceral transplantation in the past few decades and there is also increasing trend in patient and graft survival primarily due to improved patient selection, advances in immunosuppression, and improved perioperative management. This review summarizes the various key elements in patient selection, types of grafts, and updates in the perioperative management involved in multivisceral transplantation.

Abstract
Epstein-Barr virus (EBV) is associated with several malignancies, including post-transplant lymphoproliferative disorder (PTLD). Conventional treatments for PTLD are often successful, but risk organ rejection and cause significant side effects. EBV-specific cytotoxic T lymphocytes (CTLs) generated in vitro from peripheral blood lymphocytes provide an alternative treatment modality with few side effects, but autologous CTLs are difficult to use in clinical practice. Here we report the establishment and operation of a bank of EBV-specific CTLs derived from 25 blood donors with human leucocyte antigen (HLA) types found at high frequency in European populations. Since licensure, there have been enquiries about 37 patients, who shared a median of three class I and two class II HLA types with these donors. Cells have been infused into ten patients with lymphoproliferative disease, eight of whom achieved complete remission. Neither patient with refractory disease was matched for HLA class II. Both cases of EBV-associated non-haematopoietic sarcoma receiving cells failed to achieve complete remission. Thirteen patients died before any cells could be issued, emphasizing that the bank should be contacted before patients become pre-terminal. Thus, this third party donor-derived EBV-specific CTL cell bank can supply most patients with appropriately matched cells and most recipients have good outcomes.

Abstract
Post-transplantation lymphoproliferative disease (PTLD) of the gastrointestinal (GI) tract is often recognized in transplant recipients. Small bowel recipients are prone to develop GI disease due to the higher incidence of Epstein-Barr Virus (EBV) infection and enteritis as a consequence of heavy immunosuppressive regimens. So far treatment has been based on anti-CD20 therapy (Rituximab), modulation of immunosuppression, antiviral therapy (Gancyclovir), and surgery (up to allograft enterectomy if necessary), whereas endoscopy is usually used to perform the diagnosis via biopsy. We report a case of an adult small bowel recipient, who underwent transplantation due to Gardner's Syndrome 6 years earlier and was EBV positive. A native rectal PTLD was treated using opertive endoscopy combined with antiviral therapy using 4 courses of Rituximab for positive pelvic lymph nodes in addition to reduced immunosuppression. Two years after treatment the recipient is alive and disease-free with a functional graft.

Abstract
PURPOSE OF REVIEW There have been 26 cases of facial transplantation reported, and three deaths, 11.5%. Mortality raises the issue of risk versus benefit for face transplantation, a procedure intended to improve quality of life, rather than saving life. Thus, one of the most innovative surgical procedures has opened the debate on the ethical, legal, and philosophical aspects of face transplantation. RECENT FINDINGS Morbidity in face transplant recipients includes infections and metabolic consequences. No graft loss caused by technical failure, hyperacute, or chronic graft rejection or graft-versus-host disease has been reported. One case of posttransplant lymphoproliferative disorder, 3.45% and one case of lymphoma in an HIV-positive recipient were reported. Psychological issues in candidates can include chronic pain, mood disorders, preexisting psychotic disorders, post-traumatic stress disorder (PTSD), and substance abuse. SUMMARY Early publications on ethical aspects of face transplantation focused mainly on informed consent. Many other ethical issues have been identified, including lack of coercion, donor family consent and confidentiality, respect for the integrity of the donor's body, and financial promotion of the recipient and transplant team, as well as the cost to society for such a highly technical procedure, requiring lifelong immunosuppression.

Abstract
Complex multiorgan failure may require simultaneous transplantation of several organs, including heart-lung, kidney-pancreas, or multivisceral transplantation. Solid organ transplantation can also be combined with hematopoietic stem cell transplantation to modulate immunologic response to a solid organ allograft. Combined multiorgan transplantation may offer a lower rate of allograft rejection and lower immunosuppression needs. In recent years, intestinal and multivisceral transplantations became viable as a rescue treatment for patients with irreversible intestinal failure who can no longer tolerate total parenteral nutrition with 70% survival after 5 years which is comparable to other types of solid organ allografts. Post-transplant neurologic complications were reported in up to 86% of allograft recipients and greatly overlap in intestinal and multivisceral allograft recipients, without a significant effect on the outcome of transplantation. Other common organ combinations in multiorgan transplantation include kidney-pancreas, which is mostly used for patients with renal failure and uncontrolled diabetes, and heart-lung for patients with congenital heart disease and idiopathic pulmonary arterial hypertension. Kidney-pancreas transplantation frequently results in an improvement of diabetic complications, including diabetic neuropathy. Heart-lung allograft recipients have very similar clinical course and spectrum of neurologic complications to lung transplant recipients. At this time there are no reports of an increased risk of graft-versus-host disease with combined transplantation of solid organ allograft and hematopoietic stem cells. Chronic immunosuppression and complex toxic-metabolic disturbances after multiorgan transplantation create a permissive environment for development of a wide spectrum of neurologic complications which largely resemble complications after transplantations of individual components of complex multiorgan allografts.

Abstract
In the past decade, substantial improvements in patient and graft survival for pancreas and small bowel transplants have been achieved. Despite this progress, many patients still develop neurologic complications in the course of their illness. Small bowel transplants produce more neurologic complications because of the complex metabolic environment in which the procedure is performed and because of the intense immune suppression necessitated by the greater immunogenicity of the intestinal mucosa. Pancreas transplants stabilize and/or improve the signs and symptoms of diabetic neuropathy over time. Because transplantation of the pancreas is often coupled with a kidney transplant and small intestine with liver, neurologic complications in these patients sometimes reflect problems involving the organ partner or both organs. The spectrum of neurologic complications for pancreas and small bowel transplant recipients is similar to other organ transplants but their frequency varies depending on the type of transplant performed.

Abstract
Few studies examined the clinicopathologic features of PTLD arising in pediatric SBT patients. Particularly, the association between ATG and PTLD in this population has not been described. Retrospective review of 81 pediatric patient charts with SBT--isolated or in combination with other organs--showed a PTLD incidence of 11%, occurring more frequently in females (median age of four yr) and with clinically advanced disease. Monomorphic PTLD was the most common histological subtype. There was a significant difference in the use of ATG between patients who developed PTLD and those who did not (p < 0.01); a similar difference was seen with the use of sirolimus (p < 0.001). These results suggested a link between the combination of ATG and sirolimus and development of more clinically and histologically advanced PTLD; however, the risk of ATG by itself was not clear. EBV viral loads were higher in patients with PTLD, and median time between detection of EBV to PTLD diagnosis was three months. However, viral loads at the time of PTLD diagnosis were most often lower than at EBV detection, thereby raising questions on the correlation between decreasing viral genomes and risk of PTLD.

Abstract
PTLDs are a well-recognized and potentially fatal complication after intestinal transplantation. We analyzed the incidence, clinical features, and outcome in a 63 intestinal transplantation series performed in our unit between October 1999 and July 2011. Types of graft included ISB (n = 23), LSB (n = 20), and MV (n = 20). Patients were categorized into three groups of immunosuppression: I (n = 43) received basiliximab, tacrolimus, and steroids; II (n = 11) thymoglobulin and tacrolimus, and III (n = 9) alemtuzumab and tacrolimus. EBV status was serially assessed. All PTLD cases were biopsied to establish histopathological diagnosis. The incidence of PTLD was 14.2% (9/63). Median onset of PTLD after transplant was four months (range: 0.5-28), within first postoperative year in 6 (66.6%) patients. Fever was the most common symptom. Graft removal was needed in four patients (44%). The patient survival rate was 66.6% (6/9). We have not found any association between PTLD and immunosuppression regimen or transplant type. However, there was a statistical association with EBV active infection.

Impact of positive flow cytometry crossmatch on outcomes of intestinal/multivisceral transplantation: role anti-IL-2 receptor antibody. Transplantation 2013; 95:1160-6. [PMID: 23435456 DOI: 10.1097/tp.0b013e3182888df0] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/22/2022]
Abstract
BACKGROUND Positive crossmatch may be associated with an increased risk of acute rejection (AR) and worse overall outcomes after intestinal/multivisceral (MV) transplantation. However, the evidence from published studies in this setting is sparse and contradictory. This study reports the impact of positive flow cytometry crossmatch on clinical outcomes after intestinal/MV transplantation and the use of anti-interleukin (IL)-2 receptor antibody as a maintenance immunosuppressant. METHODS Records of all intestinal/MV transplants from 2003 to 2010 were reviewed. Flow cytometry was used to evaluate T- and B-cell crossmatch status. Standard immunosuppression included rabbit anti-thymocyte globulin-rituximab induction with tacrolimus and steroid maintenance. From 2008 onwards (second era), monthly anti-IL-2 receptor antibody was added to the maintenance immunosuppression in patients receiving liver-excluding transplants. RESULTS Of 131 intestinal/MV transplants, 27 (21%) had a positive crossmatch. Positive crossmatch was not associated with an increased incidence of AR and graft loss (30% and 37% vs. 29% and 47%; P=0.94 and 0.35, respectively). This effect was maintained in liver-excluding transplants. Overall rate of AR decreased from 39% to 22% in the second era. In liver-excluding transplants, there was a significant decrease in AR from 75% to 44% with the use of anti-IL-2 receptor antibody therapy. CONCLUSIONS With rabbit anti-thymocyte globulin-rituximab induction, positive crossmatch status is not associated with worse outcomes after intestinal/MV transplantation. Use of anti-IL-2 receptor antibody as a part of maintenance immunosuppression may be beneficial in liver-excluding transplants.

Abstract
This review will describe the indications for the various small bowel containing transplants. The importance of early referral will be highlighted. Radiologists play a central role in assessing these complex patients prior to transplantation. Furthermore, in the postoperative period, radiologists play an important part in diagnosing and treating complications.
