Two patients who developed posttransplant lymphoproliferative disorder with plasmacytoid changes in the lymphocytes after heart transplant are described. The first case is one of multiple myeloma, and the second is a case of lymphoma with plasmacytoid features. The clinical course and the etiologic role of the immunosuppressive therapies that the patients received for heart transplantation are described. A review of posttransplant multiple myeloma and discussion of the etiology and prognosis of this entity are presented.

Post-transplant lymphoproliferative disorder (PTLD) poses a serious challenge in kidney transplant recipients. Epstein-Barr virus (EBV)-seronegative recipients have a significantly increased risk of PTLD, but few studies have investigated risk factors for PTLD in EBV-seronegative recipients in the current era of immunosuppression. This cohort study from Norway and western Denmark included first-time kidney transplant recipients between 2007-2021, and estimated the cumulative incidence, risk and prognosis of PTLD.

Background: Epstein-Barr virus (EBV) chronic high viral load (CHVL) may be defined by >16 000 copies/mL whole blood or >200 copies/10 peripheral blood mononuclear cells in >50% samples exceeding 6 mo. EBV CHVL has only been characterized in a few small pediatric studies, with heterogeneous results and unclear clinical significance.
Methods: This single-center observational study evaluated adult and pediatric kidney transplant recipients transplanted between 2010 and 2021 on tacrolimus/mycophenolate-based/prednisone immunosuppression.

Background: Prior studies indicate that 1% to 4% of Epstein-Barr virus (EBV)-seronegative recipients of EBV-seropositive donor (EBV D+/R-) kidneys develop posttransplant lymphoproliferative disorder (PTLD). However, these estimates are based on limited data that lack granularity.
Objective: To determine the associations between pretransplant EBV D+/R- and recipient EBV-seropositive status (R+) and the outcomes of PTLD and graft and patient survival among adult kidney transplant recipients.

Here, we report a case of Epstein-Barr virus-positive central nervous system-post-transplant lymphoproliferative disorder (CNS-PTLD) patient who failed to achieve complete metabolic remission (CMR) after successively trying a methotrexate-based regimen combined with orelabrutinib or whole-brain radiotherapy and encountered intracranial hemorrhage during orelabrutinib treatment. Ultimately, the patient achieved CMR after one cycle of acalabrutinib in combination with temozolomide, teniposide, liposomal doxorubicin, dexamethasone, and rituximab (TEDDi-R). Following another cycle of TEDDi-R treatment, he has been receiving acalabrutinib maintenance up to now and remained in CMR.

Background: In vivo T-cell depletion with antithymocyte globulin (ATG), especially at high-doses has been shown to be associated with increased incidence of infections after allogeneic hematopoietic stem cell transplantation (HSCT). However, it remains unclear whether ATG, even at low-doses increases the risk of posttransplant infections in the high-risk HSCT setting.
Patients And Methods: We conducted a single-center retrospective study of viral and fungal infections early after transplantation, using the data from 82 patients with hematological malignancies.
