Ptld liver transplant

Post-transplant lymphoproliferative disorder (PTLD) is a condition that is highly variable in presentation but life-threatening for post-transplant, immunosuppressed patients. Current standard management in PTLD sees the use of a chemoimmunotherapy regimen similar to the management of diffuse large B-cell lymphoma. Here, we discuss the case of a 33-year-old male with a history of renal transplant, hemodynamically stable, who presented with fevers and night sweats lasting one month. Investigations revealed multiple masses in his liver, the largest of which was biopsied and revealed diffuse large B-cell lymphoma...

BACKGROUND: Post-transplant lymphoproliferative disorder (PTLD) is a significant complication after liver transplantation. Research on the diagnostic value of the Fluorine-18 fluorodeoxyglucose positron emission tomography/computerized tomography (18 F-FDG PET/CT) metabolic parameters of PTLD in pediatric liver transplantation (pLT) recipients is limited. This study sought to evaluate the diagnostic efficacy of 18 F-FDG PET/CT in differentiating between PTLD and non-PTLD lymphadenopathy in pLT recipients...

Patients post liver transplant (LT) with progressive familial intrahepatic cholestasis type 1 (PFIC-1) often develop progressive graft steatohepatitis, intractable diarrhea, and growth failure. A total internal biliary diversion (TIBD) during an LT may prevent or reverse these adverse events. Children with PFIC-1 who underwent an LT at our institute were divided into 2 groups, A and B based on the timeline where we started offering a TIBD in association with LT. Pre-LT parameters, intraoperative details, and posttransplant complications like graft steatosis and diarrhea were also analyzed between the 2 groups, and their growth velocity was measured in the follow-up period...

BACKGROUND: Immunosuppression in solid organ transplantation (SOT) increases the risk of Epstein-Barr virus (EBV) DNAemia, which may herald development of posttransplant lymphoproliferative disease (PTLD). Few studies have characterized the incidence, risk factors, and clinical impact of EBV DNAemia in adult SOT recipients (SOTR). METHODS: A single-center, retrospective review of adult (≥18 years) SOTR between 01 January 2015 and 31 December 2019 was conducted...

INTRODUCTION: Post-transplant lymphoproliferative disorder (PTLD) is a clinically heterogeneous potentially fatal complication of pediatric liver transplantation (PLT). We determined the prevalence, complications, and associated factors for PTLD in PLT recipients from Wits Donald Gordon Medical Centre, South Africa from January 2012 to August 2019. METHODS: We performed a retrospective record review of 150 PLT recipients. RESULTS: Histologically proven PTLD occurred in 17/150 PLT recipients (11...

Post- transplantation lymphoproliferative disorders (PTLD) are uncommon neoplasms that complicate the post transplantation period. The incidence of PTLD and outcome post liver transplantation is sparsely described. Children who undergo liver transplantation are at higher risk of PTLD than adults. Risk factors for PTLD include the level of immunosuppression and Epstein-Barr virus status. Immunosuppression in post-transplant patients can cause uncontrolled expansion of B cells. The diagnosis requires high degree of clinical suspicion, radiological evaluation, and tissue biopsy...

Posttransplant lymphoproliferative disorder (PTLD) is a rare and serious complication of kidney transplantation (KT), with 85% of cases being of B cell lineage. We present a case of T cell PTLD (T-PTLD) that rapidly progressed to liver failure, septic shock, and death despite various therapeutic interventions. A 50-year-old woman underwent ABO- and human leukocyte antigen-compatible preemptive living donor KT for diabetic endstage kidney disease under basiliximab induction therapy. During routine monitoring, 2 months after KT, her Epstein-Barr (EB) viral load was found to be elevated to 318,443 copies/mL...

BACKGROUND: Posttransplant lymphoproliferative disorder is one of the most severe complications after transplantation, caused by uncontrolled proliferation of Epstein-Barr virus-positive B-cells in the setting of chronic immunosuppression. As one of the biggest transplant centers worldwide, we observed a potential increase in the number of patients with posttransplant lymphoproliferative disorder presenting with gastrointestinal symptoms in 1 year, during the coronavirus disease 2019 pandemic...

Post-transplant lymphoproliferative disease (PTLD) is a rare but serious complication of liver transplantation (LT) with morbidity and mortality. The risk factors for PTLD in adults are ill-defined. This study aimed to assess the risk factors for PTLD after LT in adults. All adult LT recipients between 1986 and 2016 from 2 centers in the Netherlands were included, with follow-up until 2020. PTLD was diagnosed according to the World Health Organization (WHO) classification. Potential risk factors for PTLD were assessed using multivariate Cox regression analysis...

Here, we describe a rare case of malignant lymphoma after liver transplantation for liver cirrhosis caused by human immunodeficiency virus (HIV) and hepatitis C virus (HCV) co-infection. A male patient was diagnosed with hemophilia A at 8 months of age. Since then, he had been receiving blood products, which led to HIV and HCV co-infection. His HIV viral load was suppressed with antiretroviral therapy, and a sustained virologic response was achieved for HCV using direct-acting antivirals. However, his decompensated liver cirrhosis progressed, and deceased donor liver transplantation was performed...

PURPOSE: Post-transplantation lymphoproliferative disorders (PTLDs) after hematopoietic stem transplantation (HCT) or solid organ transplantation (SOT) result in poorer outcomes, including death. There are limited large cohort data on the incidence and natural course of PTLD in Asians. MATERIALS AND METHODS: We investigated PTLD using Korean national health insurance claims data of 47,518 patients who underwent HCT or SOT in 2008-2020. Patient demographics, time and type of PTLD diagnosis, type of PTLD treatment, and death data were collected...

Post-transplant lymphoproliferative disease (PTLD) is a rare complication accompanying organ transplantation. Herein, we presented 3 cases of PTLD with different primary sites. All three patients presented with symptoms in the corresponding organs or sites and the latter two patients started with atypical symptoms of infections. The first two patients who developed the disease about a year after liver transplantation both had EBV infections. All three patients received immunosuppressant reduction and antiviral therapy...

Multivisceral transplant (MVTx) refers to a composite graft from a cadaveric donor, which often includes the liver, the pancreaticoduodenal complex, and small intestine transplanted en bloc. It remains rare and is performed in specialist centres. Post-transplant complications are reported at a higher rate in multivisceral transplants because of the high levels of immunosuppression used to prevent rejection of the highly immunogenic intestine. In this study, we analyzed the clinical utility of 28 18 F-FDG PET/CT scans in 20 multivisceral transplant recipients in whom previous non-functional imaging was deemed clinically inconclusive...

BACKGROUND: ND2 in Ho Chi Minh City is currently the only public center that performs PLT in Southern Vietnam. In 2005, the first PLT was successfully performed, with support from Belgian experts. This study reviews the implementation of PLT at our center and evaluates the results and challenges. METHODS: Implementation of PLT at ND2 required medico-surgical team building and extensive improvement of hospital facilities. Records of 13 transplant recipients from 2005 to 2020 were studied retrospectively...

Chronic Epstein-Barr virus (EBV) infection after pediatric organ transplantation (Tx) accounts for significant morbidity and mortality. The risk of complications, such as posttransplant lymphoproliferative disorders, in high viral load (HVL) carriers is the highest in heart Tx recipients. However, the immunologic signatures of such a risk have been insufficiently defined. Here, we assessed the phenotypic, functional, and transcriptomic profiles of peripheral blood CD8+ /CD4+ T cells, including EBV-specific T cells, in 77 pediatric heart, kidney, and liver Tx recipients and established the relationship between memory differentiation and progression toward exhaustion...

The use of CD19 chimeric antigen receptor T-cell (CAR-T) therapy for relapsed/refractory solid organ transplantation (SOT)-related post-transplant lymphoproliferative disorder (PTLD) is not well studied. We conducted a multicentre, retrospective analysis of adults with relapsed/refractory SOT-associated PTLD. Among 22 relapsed/refractory SOT-PTLD patients, the pathology was monomorphic B cell. Prior SOTs included 14 kidney (64%), three liver (14%), two heart (9%), one intestinal (5%), one lung (5%), and one pancreas after kidney transplant (5%)...

Post-transplant lymphoproliferative disorders (PTLD) are typically Epstein-Barr virus (EBV)-associated lymphoid or plasmacytic proliferations that occur when immunosuppressed after transplantation. Only 2 cases of primary central nervous system (PCNS) classic Hodgkin lymphoma PTLD and 1 case of PCNS Hodgkin lymphoma-like PTLD have been previously reported. A 59-year-old male presented with malaise, headaches, and dizziness; neuroimaging revealed a 1.7-cm right cerebellar mass and a 0.6-cm right frontal mass...

Data on the potential benefits and risks of induction therapy in pediatric liver transplantation (LT) are limited. This was a retrospective cohort study of 2748 pediatric LT recipients at 26 children's hospitals between January 1, 2006 to May 31, 2017 using data from the pediatric health information system linked to the United Network for Organ Sharing database. The induction regimen was obtained from the pediatric health information system day-by-day pharmacy resource utilization. Cox proportional hazards evaluated the association of induction regimen (none/corticosteroid-only, nondepleting, and depleting) on patient and graft survival...

BACKGROUND: Posttransplant lymphoproliferative disease (PTLD) is a serious complication after pediatric liver transplantation (pLT), which may lead to death. 18 F-FDG PET/CT is rarely considered in PTLD after pLT and lacks clear diagnostic guidelines, especially in the differential diagnosis of nondestructive PTLD. The aim of this study was to find a quantifiable 18 F-FDG PET/CT index to identify nondestructive PTLD after pLT. METHODS: This retrospective study collected the data of patients who underwent pLT, postoperative lymph node biopsy, and 18 F-FDG PET/CT at Tianjin First Central Hospital from January 2014 to December 2021...
