UNLABELLED Tolerance after treatment and recovery from posttransplant lymphoproliferative disease (PTLD) have been described but little is known about the immunology. The objective of this study is to evaluate the immunity of pediatric recipients who recovered from PTLD. MATERIALS AND METHODS Pediatric recipients who recovered from PTLD after liver transplant and twice the number of recipient...

A clinical trial of intestinal transplantation was initiated at the University of Pittsburgh in May 1990. Eleven children received either a combined liver/small bowel graft (n = 8) or an isolated small bowel graft (n = 3). Induction as well as maintenance immunosuppression was with FK-506 and steroids. Four patients were male, and seven were female; the age range was 6 months to 10.2 years. The...

A 19-year-old woman with end-stage renal failure due to congenital kidney disease underwent a living-donor renal transplant in 2006. Eight years later, she was diagnosed with EBV MYC translocation– confirmed BL-PTLD stage IVB (Figure 1) while on treatment with mycophenolate mofetil (MMF), tacrolimus, and low-dose steroids. EBV viral load was very high (5.84 log IU/mL). Due to the aggressive pre...

Allograft liver biopsy specimens (n = 24) obtained in the clinical setting of primarily extrahepatic posttransplant lymphoproliferative disease (PTLD) were studied for histopathology, lymphocyte subsets, and Epstein-Barr virus (EBV)-encoded EBER RNA. Acute rejection was found in 20 (83.3%) of 24 biopsy specimens and graded as indeterminate in 7 (35%) of 20 (35%), mild in 3 (15%) of 20, and mode...

Epstein-Barr virus (EBV) encodes oncogenic information and, oftentimes concomitant with host immunosuppression, gives rise to malignancies in all major categories of lymphoma defined by the World Health Organization.1 Here, we conditionally evicted the viral extrachromosomal genome from tumor cells in vitro to examine the role of EBV in different lymphomas, including Burkitt lymphoma (BL) and p...

epstein-barr virus (ebv) was discovered 50 years ago from an african burkitt lymphoma cell line. ebv-associated lymphoproliferative disorders (lpds) are life-threatening diseases, especially in children. in this article, we review ebv-associated lpds, especially in the area of primary immunodeficiency disease (pid). we searched pubmed for publications with key words including ebv infection, lym...

Epstein-Barr virus (EBV) is associated with posttransplant lymphoproliferative disease (PTLD), which is a leading cause of cancer death in recipients of transplants. We investigated the role of plasmacytoid dendritic cells (PDCs) in the development of EBV infection and the onset of lymphoproliferative disease (LPD) in humanized NOD-SCID mice and studied the effect of EBV on PDC function. NOD-SC...

Lactic acidosis is a standard indicator for oxygen debt and some other very significant causes. We describe a case of liver transplant patient presenting with vague abdominal pain and lactic acidosis without any liver dysfunction/failure/ischemia/rejection or sepsis. The imaging studies showed vague bowel edema and normal hepatic perfusion. The patient continued to deteriorate with rising lacti...
