BACKGROUND: Invasive fungal infections (IFI) represent a common side effect of allogeneic hematopoietic stem cell transplant (allo-SCT), resulting in increased non relapse mortality (NRM) and reduced overall survival (OS) rates. 75-days of Fluconazole 400 mg/day represents the standard primary antifungal prophylaxis (PAP) after allo-SCT, especially for low-risk transplants. However, the ideal dosage of fluconazole has never been tested. METHODS: Here we report the experience of our institution on 113 consecutive patients receiving an allo-SCT from a HLA identical sibling between 1999 and 2015, where PAP consisted of fluconazole 100 mg/day only during the pre-engraftment phase...

BACKGROUND: Although identifying cytological viral inclusions (decoy cells) in the urine is relatively easy, distinguishing between Polyomaviruses BKV and JCV is not possible. Few studies have been published regarding JCV detection in kidney transplant recipients. OBJECTIVE: To evaluate the incidence of BKV and JCV DNA in archival slides of urine cytospin material from renal transplant patients. METHODS: A total of 44 urine specimens were evaluated cytologically for the presence of viral inclusions (decoy cells) and by nested polymerase chain reaction to differentiate between JCV and BKV in DNA isolated from archival slides of urine cytospin material...

Posttransplant lymphoproliferative disorder (PTLD) is a malignancy caused by the immunosuppression that occurs after transplantation. It is primarily a nodal lesion but frequently it involves extranodal masses. Treatment is usually by reducing immunosuppressive therapy. Testicular lymphoma as PTLD is notably rare in documented literature and there is limited evidence of definitive treatment guidelines. This manuscript describes a patient who developed diffuse large B-cell lymphoma of his right testis one year following kidney transplantation...

Adaptive immunity is initiated by T cell recognition of specific antigens presented by major histocompatibility complexes (MHCs). MHC multimer technology has been developed for the detection, isolation, and characterization of T cells in infection, autoimmunity, and cancer. Here, we present a simple, fast, flexible, and efficient method to generate many different MHC class I (MHC I) multimers in parallel using temperature-mediated peptide exchange. We designed conditional peptides for HLA-A*02:01 and H-2Kb that form stable peptide-MHC I complexes at low temperatures, but dissociate when exposed to a defined elevated temperature...

We present a middle-aged woman complaining of weakness, lethargy and weight loss for 6 months. Positron emission tomography (PET)/CT scan revealed huge bilateral adrenal masses with intense 18F-fluorodeoxyglucose avidity. Biopsy and immunohistochemical staining were compatible with mantle cell lymphoma (MCL). The patient received six cycles of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) followed by four cycles of intrathechal methotrexate chemotherapy. Bone marrow aspiration biopsy was performed for initial staging and also before bone marrow transplantation...

Background -While c-Kit+ adult progenitor cells were initially reported to produce new cardiomyocytes in the heart, recent genetic evidence suggests that such events are exceedingly rare. However, to determine if these rare events represent true de novo cardiomyocyte formation we deleted the necessary cardiogenic transcription factors Gata4 and Gata6 from c-Kit-expressing cardiac progenitor cells (CPCs). Methods - Kit allele-dependent lineage tracing and fusion analysis was performed in mice following simultaneous Gata4 and Gata6 cell-type specific deletion to examine rates of putative de novo cardiomyocyte formation from c-Kit+ cells...

Uncovering the cellular and molecular mechanisms by which hematopoietic stem cell (HSC) self-renewal is regulated can lead to the development of new strategies for promoting ex vivo HSC expansion. Here, we report the discovery that alternative (M2)-polarized macrophages (M2-MΦs) promote, but classical (M1)-polarized macrophages (M1-MΦs) inhibit, the self-renewal and expansion of HSCs from mouse bone marrow (BM) in vitro. The opposite effects of M1-MΦs and M2-MΦs on mouse BM HSCs were attributed to their differential expression of nitric oxide synthase 2 (NOS2) and arginase 1 (Arg1), because genetic knockout of Nos2 and Arg1 or inhibition of these enzymes with a specific inhibitor abrogated the differential effects of M1-MΦs and M2-MΦs...
