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: Revaccination after hematopoietic stem cell transplantation (HSCT) is necessary to compensate for the loss of immunological memory. The aims of this study were to evaluate the adherence to revaccination schedule and the humoral immune response to different vaccine antigens in HSCT pediatric and young adult patients. METHODS: Patients submitted to HSCT for over 3 years were recruited. After written informed consent, a questionnaire was filled in, the vaccination card was analyzed, a blood sample was collected and tested by ELISA for diphtheria, Haemophilus influenzae type b (Hib), hepatitis A, hepatitis B, tetanus, measles, rubella and varicella antibodies...

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...

Primary myelofibrosis (PMF) is a myeloproliferative neoplasm (MPN) in which dysregulation of the Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling pathways is the major pathogenic mechanism. Most patients with PMF carry a driver mutation in the JAK2, MPL (myeloproliferative leukemia), or CALR (calreticulin) genes. Mutations in epigenetic regulators and RNA splicing genes may also occur, and play critical roles in PMF disease progression. Based on revised World Health Organization diagnostic criteria for MPNs, both screening for driver mutations and bone marrow biopsy are required for a specific diagnosis...

INTRODUCTION: Graft-versus-host disease (GVHD) is caused by a pathologic and destructive response of the organism as a result of the interaction between donor immunocompetent T lymphocytes and the recipient tisular antigens. It's considered the most serious complication of hematopoietic stem cell transplantation, most frequently described after bone marrow transplantation (BMT). The skin is usually the first and most commonly affected organ, in both acute and chronic, with a variable clinical spectrum of presentation...

BACKGROUND: Autoimmune hemolytic anemia (AIHA) is caused by autoantibodies to red blood cells (RBCs), which can be panreactive and/or specific to Rh/other blood group antigens. We report a severe case of AIHA after bone marrow transplantation (BMT) due to autoanti-D triggered by reactivation of Epstein-Barr virus (EBV) infection. A combined strategy of D- RBC transfusion and administration of anti-CD20 monoclonal antibody (MoAb) resolved the hemolysis. CASE REPORT: A 33-year-old male underwent allogeneic BMT from an ABO-identical and HLA-matched unrelated male donor...

Preemptive antiviral therapy based on detecting cytomegalovirus (CMV) DNAemia above a preestablished threshold is the mainstay strategy for the prevention of CMV disease in allogeneic hematopoietic stem cell transplant (allo-HSCT) recipients; nevertheless, CMV DNAemia, even at low levels, may increase mortality. We investigated whether surveillance of saliva for the presence of CMV DNA may anticipate the occurrence of CMV DNAemia. This was a prospective observational study with 53 consecutively enrolled allo-HSCT recipients...

Busulfan is the most common chemotherapy agent used in allogeneic hematopoietic cell transplant (HCT) conditioning regimens. As narrow therapeutic index and interpatient variability exists in the effectiveness and toxicity of conditioning regimens, personalizing intravenous busulfan therapy is desirable. Population pharmacokinetic-based approaches have been applied to therapeutic drug monitoring for the purpose of personalizing therapy. A population pharmacokinetic analysis with the objective of personalizing therapy in Japanese patients was conducted by integrating pediatric patient data with adult patient data...

Conflicting results have been reported regarding the association between early cytomegalovirus (CMV) reactivation and relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This prompted us to evaluate the impact of CMV reactivation on outcomes of 155 consecutive adult patients transplanted in our institution. In our study, CMV reactivation did not affect cumulative incidence (CI) of relapse in patients with lymphoproliferative disorders. However, the CI of relapse in patients with myeloproliferative disorders (AML and MPN) was 37% (95% CI, 21-53) in patients without CMV reactivation as opposed to 17% (95% CI, 9-28) in patients with CMV reactivation (p = 0...

Refined graft-versus-host disease (GVHD)/relapse-free survival (GRFS) considers main outcomes of allogeneic stem cell transplant (HSCT), estimating long-term survival without significant morbidity as a surrogate of HSCT success. We compared GRFS in 5059 adults with acute myeloid leukemia (AML), undergoing HSCT in first complete remission from 2000 to 2015 either from a matched sibling (MSD, n = 3731) or unrelated donor (MUD, n = 1328). Median age was 49 (range: 18-76) years. Median follow-up was 32 and 60 months in MSD and MUD, respectively (p < 0...

BACKGROUND: Acute myeloid leukemia (AML) is both more common and with more biologically aggressive phenotype in the elderly. Allogenic stem cell transplantation (allo-SCT) is the best treatment option in fit patients. Either HLA-matched unrelated donor (MUD) or haploidentical (Haplo) donor are possible alternative for patients in need. METHODS: We retrospectively compared non-T-cell-depleted Haplo (n = 250) to 10/10 MUD (n = 2589) in AML patients ≥ 60 years...

Peripheral monocytes have recently been evaluated as a prognostic factor in different types of hematological malignancies. This study assessed the prognostic value of absolute monocyte count (AMC) post-transplant on the clinical outcomes of 59 patients with acute myeloid leukemia (AML) who had undergone myeloablative conditioning (MAC) allogeneic hematopoietic stem cell transplant (allo-HSCT) with busulfan and cyclophosphamide (Bu/Cy). Kaplan-Meier analysis showed that patients with a high AMC (≥ 0.57 × 109 /L) on post-transplant day (PTD) 15 had a significantly worse overall survival (OS) compared to patients with a low AMC (< 0...
