Previous studies demonstrated that the frequency of donor-versus-host-reactive cytotoxic T-cell precursors (CTL-p) before allogeneic bone marrow transplantation (BMT) from matched unrelated donors correlates with the incidence of graft-versus-host disease (GvH-D). We investigated whether clinical manifestations of GvH-D after HLA-identical sibling BMT are accompanied by an increased frequency o...

To contribute to the understanding of the role of the thymus in humans in the reconstitution of naive (CD45RA+) T cells after bone marrow transplantation (BMT), we compared T-cell regeneration in a unique situation, namely a thymectomized cancer patient (15 years old), with that of thymus-bearing patients after allogeneic BMT. These cases shared features of transplantation (total body irradiati...

Up to 60% of all children that receive to bone marrow transplantation (BMT) develop respiratory distress. It constitutes a common complication in this kind of patients, due to the increasing number of therapeutic applications of BMT and to improvement in the therapeutic approach to the problems associated with this procedure. We describe the different causes of respiratory distress after BMT in...

Introduction. In this paper we present the Braid Monodromy Type (BMT) of curves and surfaces; past, present and future. The BMT is an invariant that can distinguish between non-isotopic curves; between different families of surfaces of general type; between connected components of moduli space of surfaces and between non symplectmorphic 4-manifolds. BMT is a finer invariant than the Sieberg-Wit...

OBJECTIVES To assess the clinical effectiveness and cost-effectiveness of buprenorphine maintenance therapy (BMT) and methadone maintenance therapy (MMT) for the management of opioid-dependent individuals. DATA SOURCES Major electronic databases were searched from inception to August 2005. Industry submissions to the National Institute for Health and Clinical Excellence were accessed. REVIE...

Allogeneic bone marrow transplant (BMT) recipients have increased susceptibility to infections for prolonged periods after phenotypic reconstitution of donor cells. This immunodeficiency status is characterized by multiple T-cell functional abnormalities. This study was designed to investigate several signaling pathways involved in T-cell activation during this period of immune deficiency. In i...

Few data are available on the long-term effect of bone marrow transplantation (BMT) on growth. This study examines those factors that play a role in the final height outcome of patients who underwent BMT during childhood. Data on 181 of 230 patients with aplastic anemia, leukemias, and lymphomas who had BMT before puberty (mean age, 9.8 +/- 2.6 years) and who had reached their final height were...

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 IL-7 in an experimental stem cell trans...

Patients at a single pulmonary centre who developed obstructive lung disease after bone marrow transplantation (BMT) and lung transplantation (LT) were studied, in order to compare the clinical expression of post-transplant obstructive lung disease (PTOLD) (bronchiolitis obliterans) in these two conditions, which have so far been studied separately. Nine out of 179 patients surviving more than ...

PURPOSE/OBJECTIVES To arrive at an understanding of the lived experience of healthy donor and nondonor siblings as they transition through the bone marrow transplantation (BMT) trajectory. RESEARCH APPROACH Qualitative study guided by the philosophy of hermeneutic phenomenology. SETTING Participants' homes or the investigator's university or hospital office. PARTICIPANTS Eight siblings of...
