Post-transplant lymphoproliferative disorders (PTLD) can present as a type of malignancy that limits patient and graft survival after solid organ transplantation. Many early PTLDs are driven by the Epstein-Barr Virus (EBV). Once acquired, EBV virus establishes latency in B-cells and can reactivate under immunosuppression. The highest risk transplant type to develop PTLD are lung transplants who have newly acquired EBV from their donors (D+/R-). There are no good modalities to prevent PTLD from developing after transplant. Rituximab is a monoclonal antibody that depletes B-cells thereby also reducing the burden of EBV. However, rituximab can have toxicities when given intravenously including infusion reactions and increased risk of reactions. Furthermore, more than one dose is usually required. The Toronto Transplant program has developed a technology called ex vivo lung perfusion that repairs lungs outside of the body. Preliminary work has shown that rituximab given through the EVLP circuit can coat B-cells. We have also shown that there is no toxicity to the lung by giving rituximab. The current highly novel study proposes to treat donor lungs ex-vivo with rituximab in order to decrease the amount of B-cells and EBV in the graft. These lungs will then be transplanted into EBV negative patients with the hope that transmission of EBV would be reduced or prevented. Ten patients will be included in the current trial. Outcomes include safety, EBV viral load, and B-cell measurements in biopsies.
Chemokine receptor CXCR4 is normally expressed on T-lymphocytes, B-lymphocytes, monocytes, macrophages, neutrophils and eosinophils as well as hematopoietic stem and progenitor cells (HSPC) in the bone marrow. 68Ga-Pentixafor PET/CT represents a promising method for the in vivo assessment of the CXCR4 expression status in cancer patients, especially in hematologic malignancies. This prospective study is going to investigate whether metabolic characterization by 68Ga-Pentixafor PET/CT may be superior for diagnosis, risk stratification, and the prognostic evaluation in lymphoproliferative diseases.
This trial studies how well leflunomide works for the treatment of patients with CD30+ lymphoproliferative disorders that have come back (relapsed) or do not respond to treatment (refractory). Leflunomide may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Background: During a transplant, blood stem cells from one person are given to someone else. The cells grow into the different cells that make up the immune system. This can cure people with certain immunodeficiencies. But transplant has many risks and complications. Objective: To see if stem cell transplant can be successfully performed in people with primary immunodeficiency disease and cure them. Eligibility: People ages 4-69 for whom a primary immunodeficiency (PID) or Primary Immune Regulatory Disorder (PIRD), has caused significant health problems and either standard management has not worked or there are no standard management options, along with their donors Design: Donors will be screened under protocol 01-C-0129. They will donate blood or bone marrow. Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests CT or PET scans Before transplant, participants will have dental and eye exams. They will have a bone marrow biopsy. For this, a needle will be inserted through the skin into the pelvis to remove marrow. Participants will be hospitalized before their transplant. They will have a central catheter put into a vein in their chest or neck. They will get medications through the catheter to prevent complications. Participants will get stem cells through the catheter. They will stay in the hospital for at least 4 weeks. They will give blood, urine, bone marrow, and stool samples. They may need blood transfusions. They may need more scans. They will take more medications. Participants will have visits on days 30, 60, 100, 180, and 360, and 24 months after the transplant. Then they will have visits once a year for about 5 years
The purpose of this study is to evaluate how effective rituximab and acalabrutinib are when given as a combination treatment for newly diagnosed B cell post transplant lymphoproliferative disorder (PTLD). Currently there is no approved therapy for PTLD. Rituximab alone is commonly used and works in some cases, but not others. In addition, participants with PTLD have trouble tolerating therapies with large amounts of side effects due to their health conditions and medications for their transplant. Due to these reasons the study team is looking for a new treatment with novel targeted agents in order to improve outcomes and to minimize toxicity. Based on emerging data of clinical efficacy of acalabrutinib in B cell malignancies and an unmet need for novel therapies in PTLD, this study will investigate the use of rituximab and acalabrutinib in participants with newly diagnosed B cell PTLD.
This study will find the maximum tolerated dose (MTD) of CYNK-001 which contain NK cells derived from human placental CD34+ cells and culture-expanded. CYNK-001 cells will be given post Autologous Stem Cell Transplant (ASCT). The safety of this treatment will be evaluated, and researchers will want to learn if NK cells will help in treating Multiple Myeloma.
Transplant recipients are treated with immunosuppressive drugs to avoid rejection of the transplanted organ. As the medication impairs the immune response, it also increases the risk of serious infections and cancer in transplant recipients compared with the general population. Previous studies have shown a close association between Epstein-Barr virus (EBV) and post transplant lymphoproliferative disorder (PTLD), with frequent demonstration of the virus in lesional tissues. Transplant recipients without evidence of EBV infection prior to transplantation (EBV seronegative) are at particularly high risk of developing PTLD. Other risk factors include a high viral load. As part of a preventive approach against PTLD, several transplantation units now monitor the occurrence of EBV DNAemia after transplantation. However, there is little evidence to guide this strategy; nor is there consensus concerning either the best specimen to use for EBV analysis (whole blood or plasma) or the appropriate clinical action to take if EBV DNAemia is detected. Our aim is to estimate the incidence and clinical consequences of Epstein-Barr virus (EBV) DNAemia in whole blood and plasma in renal transplant recipients, and to determine if persistence of EBV DNAemia can predict excessive immunosuppression as indicated by the incidence of infections requiring hospitalisation, EBV driven PTLD and mortality.
Lymphoproliferative disorders (LPD) are a major cause of morbidity and mortality in immunodeficient patients. There have been isolated case reports of patients with childhood ALL who developed LPD after ALL diagnosis, without undergoing stem cell transplantation, but data regarding such cases are limited. We propose here an international collaboration, to form a comprehensive database of children who developed LPD after diagnosis of acute lymphoblastic leukemia/lymphoma

Open to individuals diagnosed in the last 3 years with high count MBL, Binet Stage A CLL, Immunoglobulin G/A/M (IgG, IgA, IgM) MGUS, asymptomatic WM not requiring treatment and smouldering myeloma not requiring treatment.
