Hematopoietic stem cell transplantation (HSCT) is a standard form of cellular therapy for patients suffering from malignant hematological diseases. However, graft-versus-host disease (GVHD) is a very serious complication and a major cause of morbidity and mortality after allogeneic HSCT. Calcineurin inhibitors, such as cyclosporine, are widely used to enhance the survival of patients who have undergone HSCT. Unfortunately, both GVHD and cyclosporine occasionally cause nephropathy. Several studies have shown that th [...]

Graft-versus-host disease (GVHD) is a serious complication that may occur in patients receiving allogeneic hematopoietic stem cell transplant (HSCT). GVHD occurs because of the immunological reaction between the donor’s T cells and the recipient’s antigens; GVHD may develop in different tissues, including the eye. Corneal perforation is an uncommon but vision-threatening manifestation of GVHD. We reported the case of a 65-year-old male patient who developed corneal perforation sequentially in both eyes 3 years afte [...]

Cytochrome P450 2J2 (CYP2J2) is one of the recently discovered enzymes that is involved in the metabolism of several drugs. It is mainly an extrahepatic enzyme which can, to some extent, explain some the drugs’ side effects such as cyclophosphamide (Cy). Cyclophosphamide is an alkylating agent that is commonly used in conditioning prior to stem cell transplantation. It is a prodrug that is bio-activated by several CYPs including CYP2J2. Cy is known to have several side effects and its extrahepatic activation by CYP [...]

The ability to successfully transplant cells and organs from a donor into an immunologically disparate recipient is one of the greatest treatment advances in the history of medicine. Nevertheless, acute and chronic rejection, graft versus host disease, and the inability to identify suitable donors continue to be challenges and limit broader application of cell and organ transplantation to the many patients that could benefit. Immunosuppression before and after allogeneic transplant has been found to dramatically im [...]

We report a case of thrombotic microangiopathy (TMA) diagnosed in the kidney allograft of a 59-year-old woman who had developed plasmacytoma type monomorphic posttransplant lymphoproliferative disorder (PTLD) 30 years after a simultaneous pancreas and kidney transplant. This report demonstrates a rare etiology of TMA in a kidney allograft occurring in association with PTLD-associated monoclonal gammopathy. The main teaching points are: 1) PTLD may be considered in the work-up of a new TMA in the immunosuppressed po [...]

In the multi-institutional platelet dose trial (PLADO Trial), there were 1,077 hematology/oncology patients ≥18 years of age who received at least one platelet transfusion. These patients were analyzed for types and severity of organ system bleeding based on baseline patient characteristics, laboratory assays, primary diagnosis, and type of treatment. Patients were randomly assigned to receive one of three different prophylactic platelet doses for morning platelet counts of ≤10 × 109 /L. Daily assessmen [...]

Bone marrow transplants remain an import source of hematopoietic stem cells for patients suffering from specific diseases like aplastic anemia, for pediatric patients with malignant and non-malignant blood cell disorders, and for situations in which graft-versus-host disease (GvHD) is a concern. Identifying the optimal donor to achieve a 3-5 x 108/kg of recipient weight TNC yield may be challenging. In an analysis of 687 consecutive donors, donor and procedure characteristics were related to TNC/kg of recipient wei [...]
