In chronic myelogenous leukemia (CML), amplification of a segment of bcr-abl messenger RNA (mRNA) by polymerase chain reaction (PCR) can be used to detect minimal residual disease after bone marrow transplantation (BMT). Previous studies have shown that this sensitive technique can often detect small numbers of leukemia cells in patients who are otherwise in complete remission. Nevertheless, th...

Chimeric-antigen-receptor (CAR) T cells targeting CD19 show dramatic remissions in refractory or relapsed acute lymphoblastic leukemia. Interleukin-6 (IL-6) has been associated with severe cytokine release syndrome (CRS) following CAR T cell treatment, leading to significant toxicity and death. CRS could be treated with an antiIL6-receptor antibody, with reversal of most of the inflammatory res...

Two children developed papillary thyroid carcinoma after allogeneic bone marrow transplantation (BMT) probably due to radiotherapy during remission and pretransplantation conditioning. Establishing a relationship between the cellular thyroid stimulating hormone (TSH) effect and development of carcinoma in cases with high serum TSH concentrations is difficult. After BMT, patients should be regul...

We studied 24 recipients of autologous bone marrow transplantation (ABMT) or allogeneic BMT (BMT) to determine whether impaired erythropoietin (Epo) response to anemia could delay full erythropoietic recovery. Observed Epo levels were compared with predicted levels based on the relationship between Epo and hematocrit in 125 control subjects. Circulating Epo levels were normal during conditionin...

BONE marrow transplantation (BMT) is an effective strategy to induce tolerance across xenogeneic barriers.l This approach has been used in the hamster-to-rat BMT model.2 However, all animals suffered from graft-vshost disease (GVHD). Although xenogeneic GVHD has been observed in other studies, it is not yet well characterized.3 Because xenograft rejection is primarily mediated by humoral mechan...

In a consecutive entry trial, the incidence and time course of decreased neutrophil function was assessed in 20 patients treated with allogeneic bone marrow transplantation (BMT). The aim of the study was to assess the prognostic value of low neutrophil function for late pyogenic infections. Chemotaxis, superoxide production, and phagocytic-bactericidal activity were studied before and 2,6,9, a...

Increasingly, bone marrow transplant (BMT) is the treatment of choice for certain hematologic diseases. BMT is, however, a risky procedure with many potentially serious complications. Some complications are the result of the conditioning regimen, a stage of transplantation that includes large doses of chemotherapy and/or radiation therapy. Conditioning-induced neutropenia and thrombocytopenia o...

To assess the clinical significance of minimal residual disease (MRD) detection by polymerase chain reaction (PCR) we analyzed samples from 26 patients with mantle cell lymphoma (MCL) who had undergone bone marrow transplantation (BMT) at the Dana-Farber Cancer Institute. The BCL-1/IgH translocation and clonally rearranged Ig heavy chain genes (IgH) provided molecular markers for detection and ...

Psoriasis is an immune-mediated dermatological disease, with T-cells have an important role in its pathogenesis. Activated CD4 and CD8 lymphocytes infiltrate the dermis and epidermis, resulting in hyperkeratosis, parakeratosis, epidermal acanthosis, elongation of the rete ridges and vascular dilatation. Before allogeneic bone marrow transplantation (BMT), the immune system of the host is effect...

Sir, Vitiligo is a common, depigmenting disorder characterized by well-circumscribed cutaneous macules devoid of melanocytes on the epidermis. Bone marrow transplantation (BMT), which has significant therapeutic benefits in haematologic disorders, such as leukaemia and aplastic anaemia, provides convincing evidence for the role of the immune system in some autoimmune diseases (1). In this repor...
