Incidence on relapse and nonrelapse mortality (NRM) of chronic graft-versus-host disease (GVHD), per National Institutes of Health (NIH) criteria, is not well defined after reduced-intensity conditioning (RIC) regimens. We analyzed the association of chronic GVHD with the risk of relapse and NRM using Cox models in 177 consecutive patients who underwent(More)
Major ABO incompatibility between donor and recipient is not considered a barrier to successful allogeneic hematopoietic stem cell transplantation (HSCT), even if it can be associated with several immunohematologic complications. Nevertheless, conflicting data still exist as to its influence on graft-versus-host disease (GVHD) incidence, relapse rate, and(More)
BACKGROUND Current grading systems in acute graft-versus-host disease (GVHD) are not able to identify patients with poor prognosis at time of onset, because they take into account maximal grade. The aim of this study was to evaluate potential predictors for overall survival at disease onset. METHODS The study sample was composed of 142 allogeneic(More)
There is no consensus on the optimal treatment of steroid-refractory acute graft-versus-host disease (SR-aGVHD) after allogeneic hematopoietic stem cell transplantation. In our center, the treatment policy has changed over time with mycophenolate mofetil (MMF) being used from 1999 to 2003, and etanercept or inolimomab after 2004. An observational study(More)
BACKGROUND Low-molecular-weight heparins (LMWHs), derived from unfractionated heparin (UFH) by different depolymerization procedures, vary in both their relative abilities to enhance the inhibition of FXa (anti-FXa) and thrombin (anti-FIIa), and in their physicochemical properties. OBJECTIVE We aimed to profile the inhibition of thrombin generation(More)
Use of umbilical unrelated cord-blood (UCB) cells as an alternative source of hematopoietic cell transplantation has been widely used mainly for patients lacking an HLA-matched donor. UCB present many advantages over bone marrow or mobilized peripheral blood from volunteer donors, such as rapid availability, absence of risk for the donor, and decreased(More)
BACKGROUND Voriconazole treatment increases early survival of allogeneic hematopoietic stem cell transplant recipients with invasive aspergillosis. We investigated whether this survival advantage translates into an increased long-term survival. DESIGN AND METHODS This retrospective study involved all patients with an invasive aspergillosis diagnosis(More)
Diabetes is associated with multiple disorders including metabolic, cellular and blood disturbances leading to vascular complications. Increased circulating levels of platelet-leukocyte aggregates (PLA) have been described in several thrombotic diseases. In this study, we have evaluated circulating PLA in diabetic patients and we have investigated whether(More)
BACKGROUND Preemptive rituximab (R) treatment decreases the incidence of Epstein-Barr virus (EBV) posttransplantation lymphoproliferative disease, but the extent of immune deficiency related to R in patients who received allogeneic hematopoietic stem-cell transplantation is unclear. The aim of our study was to evaluate the incidence of late infections and(More)
