Post-Transplant Lymphoproliferative Disorder Presenting as a Gastrointestinal Fistulous Tract in a Heart Transplant Recipient: Case Report and Literature Review. Transplant Proc 2024:S0041-1345(24)00448-2. [PMID: 39214719 DOI: 10.1016/j.transproceed.2024.07.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 06/21/2024] [Accepted: 07/12/2024] [Indexed: 09/04/2024]
Abstract
We present a challenging case of Epstein-Barr virus-related isolated small bowel post-transplant lymphoproliferative disorder (PTLD) in a pediatric heart transplant recipient presenting as recurrent gastrointestinal (GI) bleeding and subsequently a GI fistulous tract with associated intra-abdominal abscess. Diagnosis was not confirmed until exploratory laparoscopy was performed, with excision of the fistulous tract revealing evidence of PTLD on pathology. Early diagnosis of GI-PTLD remains a challenge, especially if isolated in the small intestine. Diagnosis may rely on positron emission tomography/ computed tomography scan (PET/CT) or invasive intervention to obtain appropriate tissue samples for pathology diagnosis.

Abstract
The International Pediatric Transplant Association convened an expert consensus conference to assess current evidence and develop recommendations for various aspects of care relating to post-transplant lymphoproliferative disorders after solid organ transplantation in children. In this report from the Viral Load and Biomarker Monitoring Working Group, we reviewed the existing literature regarding the role of Epstein-Barr viral load and other biomarkers in peripheral blood for predicting the development of PTLD, for PTLD diagnosis, and for monitoring of response to treatment. Key recommendations from the group highlighted the strong recommendation for use of the term EBV DNAemia instead of "viremia" to describe EBV DNA levels in peripheral blood as well as concerns with comparison of EBV DNAemia measurement results performed at different institutions even when tests are calibrated using the WHO international standard. The working group concluded that either whole blood or plasma could be used as matrices for EBV DNA measurement; optimal specimen type may be clinical context dependent. Whole blood testing has some advantages for surveillance to inform pre-emptive interventions while plasma testing may be preferred in the setting of clinical symptoms and treatment monitoring. However, EBV DNAemia testing alone was not recommended for PTLD diagnosis. Quantitative EBV DNAemia surveillance to identify patients at risk for PTLD and to inform pre-emptive interventions in patients who are EBV seronegative pre-transplant was recommended. In contrast, with the exception of intestinal transplant recipients or those with recent primary EBV infection prior to SOT, surveillance was not recommended in pediatric SOT recipients EBV seropositive pre-transplant. Implications of viral load kinetic parameters including peak load and viral set point on pre-emptive PTLD prevention monitoring algorithms were discussed. Use of additional markers, including measurements of EBV specific cell mediated immunity was discussed but not recommended though the importance of obtaining additional data from prospective multicenter studies was highlighted as a key research priority.

Abstract
Post-transplant lymphoproliferative disease (PTLD) remains a major complication of transplantation. PTLD is a rare entity and very heterogenous making consensus on diagnosis and treatment very challenging. The majority are Epstein-Barr virus (EBV) driven, CD20+ B-cell proliferations. PTLD does occur following hematopoietic stem cell transplant (HSCT), but due to the relative short risk period and efficacy of pre-emptive therapy, PTLD following HSCT will not be discussed in this review. This review will focus on the epidemiology, role of EBV, clinical presentation, diagnosis and evaluation and the current and emerging treatment strategies for pediatric PTLD following solid organ transplantation.

Abstract
BACKGROUND Pediatric heart transplant recipients are at risk for complications from prolonged exposure to immunosuppressive drugs, pharmacokinetic challenges in maintaining consistent immunosuppression, and medication non-adherence. Basiliximab (BAS), an interleukin-2 receptor antagonist, is used for induction therapy across many pediatric heart transplant centers, but use as maintenance immunosuppression has not been well described. METHODS This was a retrospective, single pediatric center cohort study of heart transplant recipients who received BAS for maintenance immunosuppression (defined as >2 monthly doses) from January 1, 2011, to December 31, 2021. RESULTS Ten patients met study criteria with a median age of 17.5 (5-22) years and median 9.6 (1.2-18.9) years since transplant at time of BAS initiation. The primary indications for BAS use were recurrent rejection (n = 4), fluctuating immunosuppression levels (n = 3), and renal dysfunction (n = 3). A median of 5.5 (3-32) monthly BAS doses were received. Three patients had a rejection event while on BAS. Calcineurin inhibitor exposure was reduced in 70% of patients. Three of the 10 patients were alive at last follow-up. There was one documented infection during BAS use, and no hypersensitivity reactions. CONCLUSIONS Monthly BAS infusions were well tolerated and allowed for reduced calcineurin inhibitor exposure in most patients. Mortality commonly occurred despite BAS use, potentially reflecting the acuity of this patient cohort. BAS can be considered for maintenance immunosuppression in pediatric patients with fluctuating immunosuppressive levels and/or renal dysfunction. More studies are needed to determine long-term outcomes and explore expanded use of BAS in the pediatric heart transplant population.

EBV Predicts Post-Pediatric Heart Transplant Malignancy; Induction Therapy and Tacrolimus Don't. Ann Thorac Surg 2021; 114:1794-1802.

Abstract
BACKGROUND Patients after heart transplantation are at increased risk for malignancy secondary to immunosuppression and oncogenic viral infections. Most common amongst children is post-transplant lymphoproliferative disorder (PTLD), occurring in 5-10% of patients. We utilized a national database to examine incidence and risk factors for post-transplant malignancy. METHODS The United Network for Organ Sharing (UNOS) database was queried for pediatric (<18 years) heart transplant recipients from 10/1987-10/2019. Kaplan-Meier analysis was performed to assess freedom from malignancy post-transplant. Cox regression was performed to generate hazard ratios (HR [95% CI]) for risk of malignancy development. RESULTS Of 8,581 pediatric heart transplant recipients, 8.1% developed malignancy over median follow-up time of 6.3 years, with PTLD compromising the majority (86.4%) of diagnosed cancers. The incidence of PTLD development was 1.3% and 4.5% at one and five years. Older age at the time of transplant was protective against the development of malignancy (HR 0.98 [0.96-0.99], p<0.001), whereas a history of previous malignancy (HR 1.9 [1.2-3.0], p=0.007) and Ebstein-Barr virus (EBV) recipient-donor mismatch (HR 1.7 [1.3-2.2], p<0.001) increased the risk. Use of induction therapy (utilized in 78.9% of the cohort) did not increase malignancy risk (p=0.355); nor did use of maintenance tacrolimus (p=0.912). CONCLUSIONS PTLD occurred after 7% of pediatric heart transplants, with risk increased by younger age and EBV mismatch, highlighting the importance of PTLD monitoring in EBV seronegative recipients. Induction therapy, utilized in the majority of pediatric heart transplants, does not seem to increase post-transplant malignancy, nor does the most commonly used calcineurin inhibitor tacrolimus.

Abstract
INTRODUCTION Post-transplant lymphoproliferative disorders (PTLDs) comprise a heterogeneous group of Epstein-Barr virus (EBV)-positive or negative lymphoid or plasmacytic lesions in solid organ or hematopoietic stem cell (HSC) transplant recipients. Although PTLDs in adults have been extensively studied, the clinicopathologic features of monomorphic B-cell PTLD in children, particularly EBV-negative forms, are still poorly understood. METHODS We retrospectively reviewed all our pediatric cases of monomorphic B-cell PTLDs diagnosed in the past 10 years. Clinical data were reviewed. Pathologic data including histologic types and EBV status were analyzed. Additional immunohistochemical stains, FISH studies, and TP53 gene mutational status were performed. RESULTS 4 of 18 cases were EBV-negative. All 4 EBV-negative cases were strikingly confined to the gastrointestinal (GI) tract or abdominal lymph nodes, while tumors in EBV-positive cases were found at various anatomic sites; 2 of 4 EBV-negative cases carried mutations in TP53 gene. Our cohort also included 2 rare types of PTLD, one plasmablastic lymphoma and one high-grade B-cell lymphoma, not otherwise specified (HGBL, NOS). CONCLUSION We report that monomorphic B-cell PTLDs in children have distinctive clinical and pathological features. More studies are needed to clarify whether and how much these pediatric PTLDs differ from their adult counterparts.

Abstract
OBJECTIVE Neonatal orthotopic heart transplantation was introduced in the 1980s as a treatment for complex congenital heart disease. Progress in single-ventricle palliation and biventricular correction has resulted in a decline in neonatal heart transplant volume. However, limited reports on neonatal heart transplants have demonstrated favorable outcomes. We report the long-term outcomes of patients with neonatal heart transplants at our institution spanning nearly 30 years. METHODS A retrospective analysis of neonatal heart transplants and neonates listed for transplant was performed at Children's Hospital Colorado. Primary outcomes were early and late survival. Secondary outcomes were rejection episodes, retransplantation, and development of cardiac allograft vasculopathy or post-transplant lymphoproliferative disease. RESULTS A total of 21 neonates underwent orthotopic heart transplantation at our institution. Among these, 10 neonates were transplanted from 1991 to 2000, 8 neonates were transplanted from 2001 to 2010, and 3 neonates were transplanted from 2011 to 2020. The average age of these patients was 17 days, and the average weight was 3.43 kg. Early survival was 95.2%. Survival at 1 and 5 years was 85.7% (confidence interval [CI], 61.9%-95.2%) and 75% (CI, 45.6%-85.5%), respectively. Of eligible patients, the 10-year and 20-year survival was 72.2% (CI, 45.1%-85.3%) and 50% (CI, 25.9%-70.1%), respectively. CONCLUSIONS Our institution reports favorable outcomes of neonatal heart transplantation. These results should be considered within the context of outcomes for patients awaiting transplant and the limited donor availability. However, the successful nature of these procedures suggest it may be necessary to reevaluate the indications for neonatal heart transplantation, particularly where risk of mortality and morbidity with palliative or corrective surgery is high.

Transplantation for congenital heart disease is associated with an increased risk of Epstein-Barr virus-related post-transplant lymphoproliferative disorder in children. J Heart Lung Transplant 2020; 40:24-32.

Abstract
BACKGROUND Children undergoing heart transplant are at higher risk of developing post-transplant lymphoproliferative disorder (PTLD) than other solid organ recipients. The factors driving that risk are unclear. This study investigated risk factors for PTLD in children transplanted at 1 of 2 United Kingdom pediatric cardiac transplantation centers. METHODS All children (<18 years, n = 200) transplanted at our institution over a 16-year period were analyzed. Freedom from PTLD was assessed using the Kaplan-Meier method and Cox proportional regression. RESULTS PTLD occurred in 17 of 71 children transplanted for congenital heart disease (CHD) and 18 of 129 transplanted for acquired cardiomyopathy (ACM). The cumulative incidence of all PTLD was 21.1% at 5 years after transplant. Median time from transplant to PTLD was 2.9 years (interquartile range: 0.9-4.6). Negative Epstein-Barr virus (EBV) serostatus pre-transplant (adjusted hazard ratio [HR]: 2.7, 95% CI: 1.3-5.6, p = 0.01) and underlying CHD (adjusted HR: 3.2, 95% CI: 1.4-7.4, p = 0.007) were independently associated with higher risk of PTLD. Age at thymectomy was significantly different between children with CHD and ACM (0.4 vs 5.5 years, p < 0.01). Median CD4+ and CD8+ T lymphocyte counts at 2 years after transplant were significantly lower in children transplanted for CHD vs ACM (CD4+: 391/µl vs 644/µl, p = 0.01; CD8+: 382/µl vs 500/µl, p = 0.01). At 5 years after transplant, those differences persisted among patients who developed PTLD (CD4+, 430/µl vs 963/µl, p < 0.01 and CD8+, 367/µl vs 765/µl, p < 0.01). CONCLUSION Underlying CHD is an independent risk factor for PTLD and is associated with a younger age at thymectomy. A persistent association with altered T lymphocyte subsets may contribute to the impaired response to primary EBV infection and increase the risk of PTLD.

A multicenter survey on post-transplant lymphoproliferative disorders in pediatric heart transplant recipients: A case for development of consensus guidelines for screening, surveillance, and treatment? Pediatr Transplant 2020; 24:e13730. [PMID: 32416037 DOI: 10.1111/petr.13730] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Revised: 03/23/2020] [Accepted: 04/13/2020] [Indexed: 01/29/2023]
Abstract
Post-transplant lymphoproliferative disorders (PTLD) are the main malignancy seen after pediatric heart transplant and are a significant cause of morbidity and mortality. Prior to the development of detailed guidelines, we sought to identify trends in screening, diagnosis, and treatment of pediatric PTLD. All Pediatric Heart Transplant Society (PHTS) institutions were surveyed. No identifiable patient information was shared. From 56 PHTS centers, 22 responses were received (39.3%). 100% agree PTLD cannot be diagnosed solely based on elevated Epstein-Barr virus (EBV) load. All respondents routinely screen for EBV by blood PCR, but frequency of screening varies. There was intermediate consensus regarding the use of computed tomography (CT) and/or positron emission tomography (PET) in surveillance management for PTLD. Most centers require a diagnostic biopsy before initiating new treatment for PTLD (14 of 18, 77.8%), but many reduce immune suppression based on elevated EBV without pathologic PTLD (16 of 22, 72.7%). Beyond immune modulation, rituximab is most commonly used (9 of 13, 69.2%). Consultation with oncology is common (17 of 17, 100%), but timing varies widely. Our survey highlights significant elements of agreement and significant practice variation among PHTS institutions regarding pediatric PTLD. Reduction of immune suppression prior to pathologic diagnosis of PTLD is a common management strategy. When this fails, rituximab is used, but is most often reserved until after confirmation of the diagnosis. Oncology subspecialists are commonly involved in these cases. Our findings highlight the need to develop improved guidelines for evaluation and treatment of pediatric PTLD.

Abstract
OBJECTIVES Due to the shortage of donor pool, there has been a need for organs with prolonged cold ischemic time. This study aims to evaluate the short-term results of different cold ischemic times in orthotopic heart transplantation based on a single-center experience in China. METHODS We retrospectively analyzed outcomes of the heart transplant patients from 1 January 2015 to 31 December 2017. The recipient population was divided into four groups. Group 1: cold ischemic time greater than 8 hours; group 2: the cold ischemic time between 6 and 8 hours; group 3: the cold ischemic time between 4 and 6 hours; and group 4: cold ischemic time less than 4 hours. Efficacy indicators included after transplant survival, infection rate, rejection rate, and complications. RESULTS The four groups have similar donor and recipient baseline characteristics (P > .05). Cold ischemic time greater than 8 hours had more cardiopulmonary bypass (CPB) time (127.62 ± 50.23 minutes; P = .003), CPB-assist time (86.14 ± 36.74 minutes; P = .047), and higher intra-aortic balloon pump (IABP) usage rate postoperatively (47.36%; P = .010). Cold ischemic time greater than 8 hours witnessed a relatively higher mortality rate compared with the other three groups (P = .115, P = .078, and P = .114) during the 2-year follow-up. Survival rates of 1 and 2 years for the four groups were 78.95%, 87.13%, 87.32%, and 87.50% and 68.42%, 85.14%, 85.92%, and 83.93%, respectively. CONCLUSION Cold ischemic time less than 8 hours can be reasonably applied to expand the heart transplantation donor pool. Cold ischemic time greater than 8 hours might result in longer CPB time, CPB-assist time, and higher IABP usage postoperatively. It might also affect the in-hospital and 2-years survival rate.
