We evaluated the efficacy, toxicity, and outcome of preemptive ganciclovir (GCV) therapy in 80 cytomegalovirus (CMV)-seropositive patients allografted between 1991 and 1996 and compared their outcome to 35 seronegative patients allografted during the same period. Both cohorts were comparable with respect to diagnosis and distribution of high- versus(More)
Cyclosporine A (CsA) and imatinib are both CYP3A4 and P-glycoprotein substrates. Concomitant use after hematopoietic stem cell transplantation (HSCT) for chronic myeloid leukemia (CML) or Philadelphia chromosome-positive (Ph+) acute lymphatic leukemia (ALL) may therefore result in a pharmacokinetic interaction. Although case reports and a recent small study(More)
OBJECTIVE Thymic output of newly developed ab T cells in humans can be measured via signal joint T-cell receptor rearrangement excision circles (sjTRECs). Deletion of the TCRD locus via dRec to psiJa recombination during TCRA rearrangement results in the production of such sjTRECs. The deleting elements dRec and psiJa are highly conserved between humans and(More)
BACKGROUND Recovery of thymopoiesis after allogeneic hematopoietic stem cell transplantation is considered pivotal for full immune competence. However, it is still unclear to what extent insufficient recovery of thymopoiesis predicts for subsequent opportunistic infections and non-relapse mortality. DESIGN AND METHODS A detailed survey of all(More)
Deficient thymopoiesis and retarded recovery of newly developed CD4(+) T cells is one of the most important determinants of impaired immunocompetence after hemopoietic stem cell transplantation. Here we evaluated whether Fms-like tyrosine kinase 3 (Flt3) ligand (FL) alone or combined with IL-7 affects T cell recovery, thymopoiesis, and lymphoid progenitor(More)
Interleukin-7 (IL-7) has been shown to enhance thymic output of newly developed T cells following bone marrow transplantation (BMT) in mice. In addition, IL-7 may affect peripheral expansion of T cells. In order to study the relative contribution of thymopoiesis versus peripheral T-cell expansion in the setting of compromised thymopoiesis, we have applied(More)
BACKGROUND AND OBJECTIVES Interleukin-7 (IL-7) has been studied for its possible immunorestorative capacities following stem cell transplantation and has been shown to enhance post-transplant immune recovery predominantly by peripheral T-cell expansion. A major concern of IL-7 is its possible aggravating effect on graft-versus-host and host-versus-graft(More)
The management of critically ill patients with haematological malignancy (HM) still shows inter- and intra-regional differences. Our objective in this updated review was to address the evidence supporting the potential treatment options, based on multidisciplinary processes, of critically ill patients with HM. A stepwise approach to the critical care(More)
