Bone Marrow Neoplasms: Neoplasms located in the bone marrow. They are differentiated from neoplasms composed of bone marrow cells, such as MULTIPLE MYELOMA. Most bone marrow neoplasms are metastatic.Bone Marrow DiseasesBone Marrow: The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.Bone Marrow Cells: Cells contained in the bone marrow including fat cells (see ADIPOCYTES); STROMAL CELLS; MEGAKARYOCYTES; and the immediate precursors of most blood cells.Neuroblastoma: A common neoplasm of early childhood arising from neural crest cells in the sympathetic nervous system, and characterized by diverse clinical behavior, ranging from spontaneous remission to rapid metastatic progression and death. This tumor is the most common intraabdominal malignancy of childhood, but it may also arise from thorax, neck, or rarely occur in the central nervous system. Histologic features include uniform round cells with hyperchromatic nuclei arranged in nests and separated by fibrovascular septa. Neuroblastomas may be associated with the opsoclonus-myoclonus syndrome. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2099-2101; Curr Opin Oncol 1998 Jan;10(1):43-51)Bone Marrow Transplantation: The transference of BONE MARROW from one human or animal to another for a variety of purposes including HEMATOPOIETIC STEM CELL TRANSPLANTATION or MESENCHYMAL STEM CELL TRANSPLANTATION.Bone and Bones: A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principle cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.Bone Remodeling: The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.Bone Marrow Examination: Removal of bone marrow and evaluation of its histologic picture.Hematopoietic Stem Cells: Progenitor cells from which all blood cells derive.Bone Density: The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.Bone Resorption: Bone loss due to osteoclastic activity.Bone Marrow Purging: Techniques for the removal of subpopulations of cells (usually residual tumor cells) from the bone marrow ex vivo before it is infused. The purging is achieved by a variety of agents including pharmacologic agents, biophysical agents (laser photoirradiation or radioisotopes) and immunologic agents. Bone marrow purging is used in both autologous and allogeneic BONE MARROW TRANSPLANTATION.Hematopoiesis: The development and formation of various types of BLOOD CELLS. Hematopoiesis can take place in the BONE MARROW (medullary) or outside the bone marrow (HEMATOPOIESIS, EXTRAMEDULLARY).Bone Neoplasms: Tumors or cancer located in bone tissue or specific BONES.Transplantation, Homologous: Transplantation between individuals of the same species. Usually refers to genetically disparate individuals in contradistinction to isogeneic transplantation for genetically identical individuals.Bone Development: The growth and development of bones from fetus to adult. It includes two principal mechanisms of bone growth: growth in length of long bones at the epiphyseal cartilages and growth in thickness by depositing new bone (OSTEOGENESIS) with the actions of OSTEOBLASTS and OSTEOCLASTS.Mice, Inbred C57BLBone Diseases: Diseases of BONES.Colony-Forming Units Assay: A cytologic technique for measuring the functional capacity of stem cells by assaying their activity.Cell Differentiation: Progressive restriction of the developmental potential and increasing specialization of function that leads to the formation of specialized cells, tissues, and organs.Bone Regeneration: Renewal or repair of lost bone tissue. It excludes BONY CALLUS formed after BONE FRACTURES but not yet replaced by hard bone.Cells, Cultured: Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.Whole-Body Irradiation: Irradiation of the whole body with ionizing or non-ionizing radiation. It is applicable to humans or animals but not to microorganisms.Transplantation, Autologous: Transplantation of an individual's own tissue from one site to another site.Radiation Chimera: An organism whose body contains cell populations of different genotypes as a result of the TRANSPLANTATION of donor cells after sufficient ionizing radiation to destroy the mature recipient's cells which would otherwise reject the donor cells.Stromal Cells: Connective tissue cells of an organ found in the loose connective tissue. These are most often associated with the uterine mucosa and the ovary as well as the hematopoietic system and elsewhere.Graft vs Host Disease: The clinical entity characterized by anorexia, diarrhea, loss of hair, leukopenia, thrombocytopenia, growth retardation, and eventual death brought about by the GRAFT VS HOST REACTION.Anemia, Aplastic: A form of anemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements.Osteogenesis: The process of bone formation. Histogenesis of bone including ossification.Flow Cytometry: Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.Leukemia: A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells. (From The Merck Manual, 2006)Bone Matrix: Extracellular substance of bone tissue consisting of COLLAGEN fibers, ground substance, and inorganic crystalline minerals and salts.Bone Transplantation: The grafting of bone from a donor site to a recipient site.Antigens, CD34: Glycoproteins found on immature hematopoietic cells and endothelial cells. They are the only molecules to date whose expression within the blood system is restricted to a small number of progenitor cells in the bone marrow.Granulocytes: Leukocytes with abundant granules in the cytoplasm. They are divided into three groups according to the staining properties of the granules: neutrophilic, eosinophilic, and basophilic. Mature granulocytes are the NEUTROPHILS; EOSINOPHILS; and BASOPHILS.Spleen: An encapsulated lymphatic organ through which venous blood filters.Osteoblasts: Bone-forming cells which secrete an EXTRACELLULAR MATRIX. HYDROXYAPATITE crystals are then deposited into the matrix to form bone.Osteoclasts: A large multinuclear cell associated with the BONE RESORPTION. An odontoclast, also called cementoclast, is cytomorphologically the same as an osteoclast and is involved in CEMENTUM resorption.Hematopoietic Stem Cell Transplantation: Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.Transplantation Chimera: An organism that, as a result of transplantation of donor tissue or cells, consists of two or more cell lines descended from at least two zygotes. This state may result in the induction of donor-specific TRANSPLANTATION TOLERANCE.Multiple Myeloma: A malignancy of mature PLASMA CELLS engaging in monoclonal immunoglobulin production. It is characterized by hyperglobulinemia, excess Bence-Jones proteins (free monoclonal IMMUNOGLOBULIN LIGHT CHAINS) in the urine, skeletal destruction, bone pain, and fractures. Other features include ANEMIA; HYPERCALCEMIA; and RENAL INSUFFICIENCY.Pancytopenia: Deficiency of all three cell elements of the blood, erythrocytes, leukocytes and platelets.Leukemia, Myeloid, Acute: Clonal expansion of myeloid blasts in bone marrow, blood, and other tissue. Myeloid leukemias develop from changes in cells that normally produce NEUTROPHILS; BASOPHILS; EOSINOPHILS; and MONOCYTES.Cell SeparationTime Factors: Elements of limited time intervals, contributing to particular results or situations.Bone Substitutes: Synthetic or natural materials for the replacement of bones or bone tissue. They include hard tissue replacement polymers, natural coral, hydroxyapatite, beta-tricalcium phosphate, and various other biomaterials. The bone substitutes as inert materials can be incorporated into surrounding tissue or gradually replaced by original tissue.Bone Diseases, MetabolicMegakaryocytes: Very large BONE MARROW CELLS which release mature BLOOD PLATELETS.

Longevity, stress response, and cancer in aging telomerase-deficient mice. (1/551)

Telomere maintenance is thought to play a role in signaling cellular senescence; however, a link with organismal aging processes has not been established. The telomerase null mouse provides an opportunity to understand the effects associated with critical telomere shortening at the organismal level. We studied a variety of physiological processes in an aging cohort of mTR-/- mice. Loss of telomere function did not elicit a full spectrum of classical pathophysiological symptoms of aging. However, age-dependent telomere shortening and accompanying genetic instability were associated with shortened life span as well as a reduced capacity to respond to stresses such as wound healing and hematopoietic ablation. In addition, we found an increased incidence of spontaneous malignancies. These findings demonstrate a critical role for telomere length in the overall fitness, reserve, and well being of the aging organism.  (+info)

Phase I study of 90Y-labeled B72.3 intraperitoneal administration in patients with ovarian cancer: effect of dose and EDTA coadministration on pharmacokinetics and toxicity. (2/551)

The tumor-associated glycoprotein 72 (TAG-72) antigen is present on a high percentage of tumor types including ovarian carcinomas. Antibody B72.3 is a murine monoclonal recognizing the surface domain of the TAG-72 antigen and has been widely used in human clinical trials. After our initial encouraging studies (M. G. Rosenblum et al., J. Natl. Cancer Inst., 83: 1629-1636, 1991) of tissue disposition, metabolism, and pharmacokinetics in 9 patients with ovarian cancer, we designed an escalating dose, multi-arm Phase I study of 90Y-labeled B72.3 i.p. administration. In the first arm of the study, patients (3 pts/dose level) received an i.p. infusion of either 2 or 10 mg of B72.3 labeled with either 1, 10, 15, or 25 mCi of 90Y. Pharmacokinetic studies demonstrated that concentrations of 90Y-labeled B72.3 persist in peritoneal fluid with half-lives >24 h after i.p. administration. In addition, 90Y-labeled B72.3 was absorbed rapidly into the plasma with peak levels achieved within 48 h, and levels declined slowly thereafter. Cumulative urinary excretion of the 90Y label was 10-20% of the administered dose which suggests significant whole-body retention of the radiolabel. Biopsy specimens of bone and marrow obtained at 72 h after administration demonstrated significant content of the label in bone (0.015% of the dose/g) with relatively little in marrow (0.005% of the dose/g). The maximal tolerated dose was determined to be 10 mCi because of hematological toxicity and platelet suppression. This typically occurred on the 29th day after administration and was thought to be a consequence of the irradiation of the marrow from the bony deposition of the radiolabel. In an effort to suppress the bone uptake of 90Y, patients were treated with a continuous i.v. infusion of EDTA (25 mg/kg/12 h x 6) infused immediately before i.p. administration of the radiolabeled antibody. Patients (3 pts/dose level) were treated with doses of 10, 15, 20, 25, 30, 35, 40, or 45 mCi of 90Y-labeled B72.3 for a total of 38 patients. EDTA administration resulted in significant myeloprotection, which allowed escalation to the maximal tolerated dose of 40 mCi. Dose-limiting toxicity was thrombocytopenia and neutropenia. Studies of plasma and peritoneal fluid pharmacokinetics demonstrate no changes compared with patients without EDTA pretreatment. Cumulative urinary excretion of the radiolabel was not increased in patients pretreated with EDTA compared with the untreated group. However, analysis of biopsy specimens of bone and marrow demonstrated that bone and marrow content of the 90Y label was 15-fold lower (<0.001% injected dose/g) than a companion group without EDTA. Four responses were noted in patients who received 15-30 mCi of 90Y-labeled B72.3 with response durations of 1-12 months. These results demonstrate the myeloprotective ability of EDTA, which allows safe i.p. administration of higher doses of 90Y-labeled B72.3 and, therefore, clearly warrant an expanded Phase II trial in patients with minimal residual disease after standard chemotherapy or for the palliation of refractory ascites.  (+info)

Double-blind randomized study on the myeloprotective effect of melatonin in combination with carboplatin and etoposide in advanced lung cancer. (3/551)

A significant myeloprotective effect of melatonin in mice treated with etoposide, cyclophosphamide or carboplatin has been reported. The present study was designed to evaluate if the same effect could be observed in patients receiving chemotherapy. Twenty previously untreated patients with inoperable lung cancer received two cycles of carboplatin (given at area under the curve 5 by the Calvert formula) on day 1 and etoposide (150 mg m(-2) i.v.) on days 1-3 every 4 weeks. Melatonin 40 mg or placebo (double-blind) was given orally in the evening for 21 consecutive days, starting 2 days before chemotherapy. Patients were randomized to receive melatonin either with the first or the second cycle. Complete blood cell count with differential was done three times per week for 3 weeks. The median age of the cohort was 60 years (range 42-69), 16 patients had non-small cell and four patients small-cell lung cancer, 12 stage III and eight stage IV disease. In a multivariate analysis including age, sex, diagnosis, stage, performance status, doses of carboplatin and etoposide, and concomitant treatment with melatonin or placebo, the haematological parameters--depth and duration of toxicity for haemoglobin, platelets and neutrophils (ANC)--were not significantly different between cycles with/without melatonin. The mean ANC nadir and the mean number of days with ANC < 0.5 x 10(9) l(-1) were 0.5 x 10(9) l(-1) and 2.5 days, respectively, with/without melatonin. We concluded that, in patients with lung cancer, melatonin given orally at a dose of 40 mg per day for 21 days in the evening, does not protect against the myelotoxic effect of carboplatin and etoposide.  (+info)

Magnetic resonance imaging of the wrist in early rheumatoid arthritis reveals progression of erosions despite clinical improvement. (4/551)

OBJECTIVES: To investigate the progression of joint damage in early rheumatoid arthritis (RA) using magnetic resonance imaging (MRI) of the wrist and determine whether this technique can be used to predict prognosis. METHODS: An inception cohort of 42 early patients has been followed up prospectively for one year. Gadolinium enhanced MRI scans of the dominant wrist were obtained at baseline and one year and scored for synovitis, tendonitis, bone marrow oedema, and erosions. Plain radiographs were performed concurrently and scored for erosions. Patients were assessed clinically for disease activity and HLA-DRB1 genotyping was performed. RESULTS: At one year, MRI erosions were found in 74% of patients (31 of 42) compared with 45% at baseline. Twelve patients (28.6%) had radiographic erosions at one year. The total MRI score and MRI erosion score increased significantly from baseline to one year despite falls in clinical measures of inflammation including erythrocyte sedimentation rate (ESR), C reactive protein (CRP), and swollen joint count (p < 0.01 for all). Baseline findings that predicted carpal MRI erosions at one year included a total MRI score of 6 or greater (sensitivity: 93.3%, specificity 81.8%, positive predictive value 93.3%, p = 0.000007), MRI bone oedema (OR = 6.47, p < 0.001), MRI synovitis (OR = 2.14, p = 0.003), and pain score (p = 0.01). Radiological erosions at one year were predicted by a total MRI score at baseline of greater than 13 (OR = 12.4, p = 0.002), the presence of MRI erosions (OR = 11.6, p = 0.005), and the ESR (p = 0.02). If MRI erosions were absent at baseline and the total MRI score was low, radiological erosions were highly unlikely to develop by one year (negative predictive value 0.91 and 0.92 respectively). No association was found between the shared epitope and erosions on MRI (p = 0.4) or radiography (p = 1.0) at one year. CONCLUSIONS: MRI scans of the dominant wrist are useful in predicting MRI and radiological erosions in early RA and may indicate the patients that should be managed aggressively. Discordance has been demonstrated between clinical improvement and progression of MRI erosion scores.  (+info)

Hematopoietic damage prior to PBSCT and its influence on hematopoietic recovery. (5/551)

BACKGROUND AND OBJECTIVE: Patients with malignancies receive chemotherapy to induce tumor remission which could damage hematopoiesis and adversely influence hematopoietic reconstitution after transplantation. In the present study we used a long-term culture (LTBMC) system and clonogenic assays to evaluate the marrow damage in patients selected to receive peripheral blood stem cell transplantation (PBSCT). DESIGN AND METHODS: Thirty-five patients - 20 with breast cancer (BC), 9 with non-Hodgkin's lymphoma (NHL) and 6 with Hodgkin's disease (HD) - were included. Bone marrow aspiration was performed one day prior to the initiation of the conditioning therapy. CFU-GM were cultured in methylcellulose with PHA-LCM. Delta assays of plastic adherent progenitor cells (PD) were performed according to Gordon's method. LTBMC were established for 5 weeks. RESULTS: There were fewer CFU-GM from all patient groups than from normal BM (p<0.05). In contrast, the number of immature progenitor cells (PD) was not decreased. The total number of CFU-GM produced by LTBMC patients was significantly reduced (p<0.05). The adherent layer from patients was often qualitatively different. In order to know whether the hematopoietic damage could affect hematopoietic reconstitution, we correlated culture data with time taken to reach peripheral cell counts. A negative correlation (r= - 0.71) was found between percentage of stromal layer and time taken to reach 20x10(9) platelets/L (tplat= 20x3-0.08% stromal layer). INTERPRETATION AND CONCLUSIONS: We can conclude that prior to PBSCT, hematopoietic function is impaired at both the level of committed progenitor cells and that of BM stroma. This damage could influence platelet recovery.  (+info)

First-line high-dose sequential chemotherapy with rG-CSF and repeated blood stem cell transplantation in untreated inflammatory breast cancer: toxicity and response (PEGASE 02 trial). (6/551)

Despite the generalization of induction chemotherapy and a better outcome for chemosensitive diseases, the prognosis of inflammatory breast cancer (IBC) is still poor. In this work, we evaluate response and toxicity of high-dose sequential chemotherapy with repeated blood stem cell (BSC) transplantation administered as initial treatment in 100 women with non-metastatic IBC. Ninety-five patients (five patients were evaluated as non-eligible) of median age 46 years (range 26-56) received four cycles of chemotherapy associating: cyclophosphamide (C) 6 g m(-2) - doxorubicin (D) 75 mg m(-2) cycle 1, C: 3 g m(-2) - D: 75 mg m(-2) cycle 2, C: 3 g m(-2) - D: 75 mg m(-2) - 5 FU 2500 mg m(-2) cycle 3 and 4. BSC were collected after cycle 1 or 2 and reinfused after cycle 3 and 4. rG-CSF was administered after the four cycles. Mastectomy and radiotherapy were planned after chemotherapy completion. Pathological response was considered as the first end point of this trial. A total of 366 cycles of chemotherapy were administered. Eighty-seven patients completed the four cycles and relative dose intensity was respectively 0.97 (range 0.4-1.04) and 0.96 (range 0.25-1.05) for C and D. Main toxicity was haematological with febrile neutropenia ranging from 26% to 51% of cycles; one death occurred during aplasia. Clinical response rate was 90% +/- 6%. Eighty-six patients underwent mastectomy in a median of 3.5 months (range 3-9) after the first cycle of chemotherapy; pathological complete response rate in breast was 32% +/- 10%. All patients were eligible to receive additional radiotherapy. High-dose chemotherapy with repeated BSC transplantation is feasible with acceptable toxicity in IBC. Pathological response rate is encouraging but has to be confirmed by final outcome.  (+info)

Ticlopidine and clopidogrel. (7/551)

The thienopyridines ticlopidine and clopidogrel are inhibitors of platelet function in vivo. Their mode of action has not been defined, but it appears that they require conversion to as yet unidentified metabolites that are noncompetitive antagonists of the platelet ADP receptor. Inhibition of platelet aggregation with these compounds is delayed until 24 to 48 hours after administration. Maximum inhibition occurs after 3 to 5 days, and recovery is slow after drug withdrawal. Ticlopidine is effective in preventing cardiovascular events in cerebrovascular, cardiovascular, and peripheral vascular disease, with an efficacy that is similar to aspirin. However, its use is associated with significant and sometimes fatal adverse reactions, specifically neutropenia and bone marrow aplasia. Gastrointestinal side effects and skin rashes are common and result in discontinuation of therapy in up to 10% of patients. Clopidogrel is at least as effective as aspirin in preventing cardiovascular events in patients with a history of vascular disease. It appears to be safer than ticlopidine, although its efficacy in acute coronary syndromes or post-coronary-stent insertion has not been reported. Important outstanding issues are whether clopidogrel adds to the benefit of aspirin and whether the combination of these agents is safe. If so, this combination may become the standard for antithrombotic therapy in cardiovascular disease.  (+info)

Measurement of vitamin B12-binding proteins of plasma. II. Interpretation of patterns in disease. (8/551)

The technique described in the preceding paper was applied to 12 abnormal sera selected for their increase in one or more B12-binding proteins. Even in the presence of large amounts of R-type binder, the ammonium sulfate technique gave a reliable separation of R binding proteins from TC II. Measurement of the TC II in abnormal sera gave results identical to those obtained by the more standard gel filtration. The R binders of four subjects with myeloproliferative disease were further separated into alpha2-R and alpha1-R. The pattern of B12 binding of polycythemia vera (PV) was an exaggeration of the normal pattern. Binding to alpha2-R was three to four times that to alpha1-R, although the total amounts bound to both were increased. In chronic myelogenous leukemia (CML), both alpha2-R and alpha1-R were also increased, but in contrast to binding in normal sera, alpha1-R predominated. In order to interpret the findings, either whole serum R or alpha1-R and alpha2-R from patients with myeloproliferative disease were subject to isoelectric focusing. Alpha2-R consisted pricipally of components isoelectric at pH 2.9, 3.0, and 3.1. These components were present in only minor amounts in normal serum and were somewhat increased in the serum of PV. These components were very much increased in the serum of CML and predominated. Alpha2-R consisted of those components isoelectric at pH 3.4,3.6, and 4.0. These components predominated in the unsaturated binding capacity of normal sera and that of PV. It was concluded that the division of plasma R binders into alpha1-R and alpha1-R by the technique described provided information useful in the study of myeloproliferative diseases.  (+info)

As far as we know, this study provides the first detailed longitudinal data from a large sample describing the natural history of individual BMLs in articular subregions, as well as at the level of the knee as a whole, and relates different types of longitudinal change in individual BMLs to the risk of cartilage loss in the same subregion of the articular surface. We found that over 30 months a substantial proportion of existing BMLs decreased in size (many resolving completely) while increase in size, including development of new BMLs, was also common. Most knees with prevalent BMLs at baseline showed either no change or changes in only one direction (increase or decrease), but a smaller proportion of knees simultaneously displayed combinations of stable, increasing and decreasing BMLs. In comparison with subregions with BMLs that were stable during the study, the risk of cartilage loss was substantially increased for enlarging or new BMLs. The risk of cartilage loss was substantially decreased ...
Bone marrow suppression also known as myelotoxicity or myelosuppression, is the decrease in production of cells responsible for providing immunity (leukocytes), carrying oxygen (erythrocytes), and/or those responsible for normal blood clotting (thrombocytes). Bone marrow suppression is a serious side effect of chemotherapy and certain drugs affecting the immune system such as azathioprine. The risk is especially high in cytotoxic chemotherapy for leukemia. Nonsteroidal anti-inflammatory drugs (NSAIDs), in some rare instances, may also cause bone marrow suppression. The decrease in blood cell counts does not occur right at the start of chemotherapy because the drugs do not destroy the cells already in the bloodstream (these are not dividing rapidly). Instead, the drugs affect new blood cells that are being made by the bone marrow. When myelosuppression is severe, it is called myeloablation. Many other drugs including common antibiotics may cause bone marrow suppression. Unlike chemotherapy the ...

For this reason it is crucial to clearly and specifically define the type of BML that is being assessed and to use terminology that is appropriate to the condition and the pathology. In light of the currently used terminology, supported by histology, it seems appropriate ...
Mayo Clinic researchers have found that azathioprine, a drug commonly used to treat autoimmune disease, may increase the risk of myeloid neoplasms. Myeloid neoplasms include a spectrum of potentially life-threatening bone marrow disorders, such as myelodysplastic syndromes and acute myeloid leukemia. The results are published in JAMA Oncology.
Inherited bone marrow failure syndromes (IBMFSs) such as Fanconi Anemia (FA) and Shwachman-Diamond syndrome (SDS) feature progressive cytopenia and a risk of acute myeloid leukemia (AML). Using deep phenotypic analysis of early progenitors in FA/SDS bone marrow samples we revealed selective survival of progenitors that phenotypically resembled granulocyte-monocyte progenitors (GMP). Whole exome and targeted sequencing of GMP-like cells in leukemia-free patients revealed a higher mutation load than in healthy controls and molecular changes that are characteristic of AML: increased G,A/C,T variants, decreased A,G/T,C variants, increased trinucleotide mutations at Xp(C,T)pT and decreased mutation rates at Xp(C,T)pG sites compared to other Xp(C,T)pX sites and enrichment for Cancer signature 1 (X indicates any nucleotide). Potential pre-leukemic targets in the GMP-like cells from FA/SDS patients included SYNE1, DST, HUWE1, LRP2, NOTCH2 and TP53. Serial analysis of GMPs from a SDS patient, who ...

The aetiology and pathogenesis of primary bone marrow oedema syndrome (BMES) remain unclear. This retrospective cross-sectional study in a large cohort of patients with BMES was performed to characterise the overall skeletal status and turnover in patients with BMES, with the aim of identifying risk factors for this disease. Patients who were diagnosed with BMES on the basis of clinical and radiological (magnetic resonance imaging) findings in our outpatient clinic were identified retrospectively. Patient history, co-existing metabolic disorders, bone metabolism parameters (serum calcium, phosphate, 25-OH-D3, bone-specific alkaline phosphatase, parathyroid hormone, and osteocalcin, and urinary deoxypyridinoline) and bone mineral density (as measured by dual-energy X-ray absorptiometry) were extracted from the medical records. Patients with secondary causes for BMES were excluded from the study. Of the 171 patients, 65 were identified without secondary cause for BMES. Of the 65 patients, 61.5% were
London, Jan 17 (IANS) Bone marrow lesions (BMLs) are likely to help predict a swiftly progressing joint disease, says a study. The research shows lesions - seen on MRI scans as regions of bone beneath the cartilage with ill-defined high signal - can help identify individuals who are more likely to suffer from the rapidly progressing osteoarthritis.. Osteoarthritis - the most common type of arthritis in the UK - can cause the joints to become painful and stiff.. Almost any joint can be affected, but it most often causes problems in the knees, hips, and small joints of the hands. It can progress at varying speeds.. "Osteoarthritis causes a significant burden to individuals and the healthcare system as a whole," said Mark Edwards, Clinical Lecturer at the University of Southampton in UK.. Individuals with BMLs lose the space within the joint at a rate that is 0.10 mm per year faster than those without BMLs, the findings showed.. The SEKOIA study, a major international osteoarthritis ...

Inherited bone marrow failure (IBMF) syndromes are a heterogeneous group of rare hematological disorders characterized by the impairment of hematopoiesis, which harbor specific clinical presentations and pathogenic mechanisms. Some of these syndromes may progress through clonal evolution, myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Most prominent are failures of DNA repair such as Fanconi Anemia and much rarer failure of ribosomal apparatus, e.g., Diamond Blackfan Anemia or...
Objectives To investigate the association between meniscal pathology and incident or enlarging bone marrow lesions (BML) in knee osteoarthritis.. Methods The authors studied subjects from the Multicenter Osteoarthritis Study aged 50-79 years either with knee osteoarthritis or at high risk of the disease. Baseline and 30-months magnetic resonance images of knees (n=1344) were scored for subchondral BML. Outcome was defined as an increase in BML score in either the tibial or femoral condyle in medial and lateral compartments, respectively. The authors defined meniscal pathology at baseline as the presence of either meniscal lesions or meniscal extrusion. The risk of an increase in BML score in relation to meniscal status in the same compartment was estimated using a log linear regression model adjusted for age, sex, body mass index, physical activity level and mechanical axis. In secondary analyses the investigators stratified by ipsilateral tibiofemoral cartilage status at baseline and ...
Our data indicate that UCBT is an excellent option for children with hereditary bone marrow failure syndromes when the donor is an HLA-matched sibling donor. Our results are in agreement with those of a previously published analysis which compared outcome of patients undergoing HLA-identical sibling UCBT with that of HLA-identical sibling bone marrow transplant recipients and showed similar overall survival in children with malignant and non-malignant diseases.16 Banks of related cord blood have been established; they are not, however, sufficiently developed despite the excellent results observed not only in marrow failure but also in other hereditary disorders such as hemoglobinopathies, metabolic disorders and congenital immune deficiencies.17,18 Another factor in favor of freezing cord blood cells from an HLA-identical sibling is the absence of risk for the donor.. An important observation is that the risk of graft failure after unrelated UCBT was high in this cohort of patients. The risk of ...
Here, we reported the case of a patient who experienced persistent bone marrow necrosis after ATRA and IDA induction therapy for APL, despite cessation of ATRA. Although ATRA-induced bone marrow necrosis has been documented,18-20 this case is notable in that our patient demonstrated continual bone marrow necrosis several months subsequent to stopping ATRA therapy. It is interesting to note that the patient had evidence of hematopoietic recovery despite the necrotic effects of ATRA and shifting to ATO treatment.. Bone marrow necrosis is conjectured to result from poor blood supply to the marrow21 or increased oxygen demand of the marrow, as evidenced in necrosis of other tissue types. The most common cause of bone marrow necrosis is malignancy, in particular hematologic malignancy, including acute leukemia.18,21,22 It is reasonable to postulate that the APL by itself could have caused the bone marrow necrosis as evidenced in this patient23; however, one would have expected necrosis on the initial ...
The hypoproliferative anemias are normochromic, normocytic, or macrocytic and are characterized by a low reticulocyte count. Hypoproliferative anemia is also a prominent feature of hematologic diseases that are described as bone marrow failure states; these include aplastic anemia, myelodysplastic syndrome (MDS), pure red cell aplasia (PRCA), and myelophthisis. Anemia in these disorders is often not a solitary or even the major hematologic finding. More frequent in bone marrow failure is pancytopenia: anemia, leukopenia, and thrombocytopenia. Low blood counts in the marrow failure diseases result from deficient hematopoiesis, as distinguished from blood count depression due to peripheral destruction of red cells (hemolytic anemias), platelets (idiopathic thrombocytopenic purpura [ITP] or due to splenomegaly), and granulocytes (as in the immune leukopenias). Marrow damage and dysfunction also may be secondary to infection, inflammation, or cancer. ...
Assessing the pathology of the synovium, its thickening and increased vascularity through ultrasound and magnetic resonance examinations (more often an ultrasound study alone) is still considered a sensitive parameter in the diagnosis of rheumatoid arthritis and in monitoring of treatment efficacy. Magnetic resonance studies showed that, aside from the joint pannus, the subchondral bone tissue constitutes an essential element in the development of rheumatoid arthritis. Bone marrow edema correlates with inflammation severity, joint destruction, clinical signs and symptoms of rheumatoid arthritis, and thus is considered a predictor of rapid radiological progression of the disease. The newest studies reveal that bone marrow edema may be a more sensitive indicator of the response to therapy than appearance of the synovium. Bone marrow edema presents with increased signal in T2-weighted images, being most visible in fat saturation or IR sequences (STIR, TIRM). On the other hand, it is hypointense and ...

TY - JOUR. T1 - Inherited SHQ1 mutations impair interaction with NAP57/dyskerin, a major target in dyskeratosis congenita. AU - Bizarro, Jonathan. AU - Meier, U. Thomas. PY - 2017/1/1. Y1 - 2017/1/1. N2 - Background: The inherited bone marrow failure syndrome dyskeratosis congenita (DC) is most frequently caused by mutations in DKC1 (MIM# 300126), the gene encoding NAP57 (aka dyskerin). The typically missense mutations modulate the interaction of NAP57 with its chaperone SHQ1, but no DC mutations have been identified in SHQ1 (MIM# 613663). Here, we report on two compound heterozygous mutations in SHQ1 in a patient with a severe neurological disorder including cerebellar degeneration. Methods: The SHQ1 mutations were identified by patient exome sequencing. The impact of the mutations was assessed in pulldown assays with recombinant NAP57. Results: The SHQ1 mutations were the only set of mutations consistent with an autosomal recessive mode of inheritance. The mutations map to the SHQ1-NAP57 ...

Bone marrow oedema (BME) and avascular osteonecrosis (AVN) are disorders of unclear origin. Although there are numerous operative and non-operative treatments for AVN, pain management in patients with AVN remains challenging. Prostaglandins play an important role in inflammatory responses and cell differentiation. It is thought that prostaglandin I2 ([PGI2] or synonoma prostacyclin) and its analogues promote bone regeneration on a cellular or systemic level. The purpose of this study was to assess the curative and symptomatic efficacy of the prostacyclin analogue iloprost in BME and AVN patients. We are reporting on 50 patients (117 bones) affected by BME/AVN who were treated with iloprost. Pain levels before, during and 3 and 6 months after iloprost application were evaluated by a visual analogue scale (VAS). The short form(SF)-36 health survey served to judge general health status before and after treatment. Harris Hip Score (HHS) and Knee Society Score (KSS) were performed as functional scores and

Shwachman syndrome is a rare genetic disorder with multiple and varied manifestations. The disorder is typically characterized by signs of insufficient absorption (malabsorption) of fats and other nutrients due to abnormal development of the pancreas (pancreatic insufficiency) and improper functioning of the bone marrow (bone marrow dysfunction), resulting in low levels of circulating blood cells (hematologic abnormalities). Additional characteristic findings may include short stature; abnormal bone development affecting the rib cage and/or bones in the arms and/or legs (metaphyseal dysostosis); and/or liver abnormalities.

Bone marrow failure syndromes (BMFS) are a group of disorders with complex pathophysiology characterized by a common phenotype of peripheral cytopenia and/or hypoplastic bone marrow. Understanding genetic factors contributing to the pathophysiology of BMFS has enabled the identification of causative genes and development of diagnostic tests. To date more than 40 mutations in genes involved in maintenance of genomic stability, DNA repair, ribosome and telomere biology have been identified. In addition, pathophysiological studies have provided insights into several biological pathways leading to the characterization of genotype/phenotype correlations as well as the development of diagnostic approaches and management strategies. Recent developments in bone marrow transplant techniques and the choice of conditioning regimens have helped improve transplant outcomes. However, current morbidity and mortality remain unacceptable underlining the need for further research in this area. Studies in mice ...

Authors: Nurgalieva Z, Liu CC, Du XL. Title: Chemotherapy use and risk of bone marrow suppression in a large population-based cohort of older women with breast and ovarian cancer.. Journal: Med Oncol 28(3):716-25. Date: 2011 Sep. Abstract: We studied 65,521 women with breast cancer and 7,420 women with ovarian cancer aged ≥ 65 identified from the 16 areas of the Surveillance, Epidemiology and End Results program linked with Medicare data during 1991-2002. Bone marrow toxicity associated with chemotherapy was defined using diagnosis codes from Medicare inpatient, outpatient and physician claims. The time to event Cox regression was utilized to estimate the risk of bone marrow toxicity. Use of anthracyclines, taxanes or platinums was associated with increased risks of short- (≤3 months) and long-term (>3 months) anemia and neutropenia in patients with breast cancer. Alkylating agents or antimetabolites were additional significant predictors of anemia in women with ovarian cancer. Patients who ...
Immune-mediated aplastic anemia resembles other bone marrow disorders such as myelodysplastic syndrome, certain infections, and leukemia. Because treatment for aplastic anemia differs from management of other diseases affecting the bone marrow, it is critically important to distinguish between these disorders when a diagnosis of aplastic anemia is suspected. Therefore, children with persistently low blood counts should be evaluated by pediatric hematologists with expertise in diagnostics and treatment of these uncommon disorders ...
Radiation therapy is not currently used for treating MDS, or myelodysplastic syndromes. MDS is a term used to describe a group of diverse bone marrow disorders that can occur when the bone marrow does not produce enough healthy blood cells. Healthy bone marrow produces immature blood cells (stem cells or blasts) that normally develop into mature, fully functional red blood cells, white blood cells or platelets. MDS can interfere with blast development and cause blasts to accumulate in the bone marrow or shorten their life span, resulting in a shortage of healthy blood cells in circulation. Because the unhealthy cells circulate throughout the body and radiation therapy can only target one specific area at a time, radiation therapy is impractical for MDS treatment.. The renowned research team in the Malignant Hematology Program at Moffitt Cancer Center is continually evaluating promising new treatment options for MDS, such as the use of antibodies to deliver radioactive materials specifically to ...

The normal reaction of bone marrow to infection or inflammation leads to an increase in the number of white blood cells, predominantly polymorphonuclear leukocytes and less mature cell forms (the
Janus Kinase 2 (JAK2) gene mutations are associated with bone marrow disorders called myeloproliferative neoplasms (MPNs) caused by the production of too many blood cells. JAK2 mutation tests help diagnose MPNs.
Although mosquito-borne illness presents a potential threat, the health and environmental impact of widespread pesticide applications may be even more detrimental. Pesticides used to kill mosquitoes and other insects have been linked to severe and chronic health problems. For example, a 1981 study concluded that pesticides caused childhood bone marrow disorders in all cases that were reviewed. A more recent study linked mosquito spraying with a 25% increased rate of autism. ...
Borderline or low levels of WBCs may be found in healthy individuals without and underlying condition or disease process. However, some causative factors of a decreased WBC levels are with the use of some medications (typically chemotherapy agents), chemical exposure (related to certain professions), infections viral/bacterial, autoimmune conditions, bone marrow dysfunction, etc. Wellbutrin or Seroquel , to my knowledge would not affect WBC levels. I hope your hematology appointment goes well ...

A thymidine (RNA constituent) analog that suppresses replication of HIV. AZT is increasingly administered in combination with other antiviral drugs. Possible side effects include bone marrow suppression leading to anemia, leukopenia, or neutropenia; nausea; muscle weakness; and headaches. ...
Property field_intro Another side to effective patient behavior The key to becoming an empowered patient is simply deciding to make your life the best it can be. People with bone marrow failure and other chronic diseases, despite certain limitations, are leading active and fulfilling lives. They have chosen to take care of themselves - living their lives to the fullest through special attention to their physical and emotional health. What you do after your diagnosis beyond treatment-related activity can make a big difference in how successful you are in meeting this new challenge.
April 23-29 is National Volunteer week - days of acknowledgement set aside each year for organizations to honor those who give selflessly of their time and talent to support the causes they care about. To help us accomplish many of our programs, events and services for the bone marrow failure community, we rely heavily on our dedicated volunteer base of over 500 patients, families and health professionals. Heres who they are and what they do to keep AAMDSIF moving forward.
It can be caused by many things- i.e. Bleeding, iron, vit B12 deficiency, red blood cell destruction, , bone marrow failure etc. It can be so severe- such as in massive bleeding- and people do die from massive bleeding if bleeding cant be controlled. In chronic case- heart failure, other organ dysfunction/failure can happen. Would you like to video or text chat with me? ...

Shwachman-Diamond syndrome (SDS) is a rare inherited bone marrow failure syndrome, characterised by neutropenia, exocrine pancreatic dysfunction and often skeletal abnormalities. To date, and to our knowledge, we report a novel genetic mutation in SDS that, we believe, is associated with minimal consequence, and report the fertility and pregnancy in this individual. ...
Thrombocytopenia - The blood also contains cells called platelets. It is their function to clot the blood when bleeding occurs. Normally, platelet counts are above 150,000 per microliter. In about 35% of patients with Shwachman-Diamond syndrome this count is below that number; this is called thrombocytopenia. Easy bruisability is one indication of thrombocytopenia, but severe bleeding is unusual. Precautions may be required before dental work or surgery, and platelet transfusions or medications may be necessary to diminish the risk of abnormal bleeding ...
Shwachman-Diamond syndrome (SDS) (OMIM #260400) is a rare inherited bone marrow failure syndrome (IBMFS) that is primarily characterized by neutropenia and exocrine pancreatic insufficiency. Seventy-five to ninety percent of patients have compound heterozygous loss-of-function mutations in the Shwachman-Bodian-Diamond syndrome (sbds) gene. Using trio whole-exome sequencing (WES) in an sbds-negative SDS family and candidate gene sequencing in additional SBDS-negative SDS cases or molecularly undiagnosed IBMFS cases, we identified 3 independent patients, each of whom carried a de novo missense variant in srp54 (encoding signal recognition particle 54 kDa). These 3 patients shared congenital neutropenia linked with various other SDS phenotypes. 3D protein modeling revealed that the 3 variants affect highly conserved amino acids within the GTPase domain of the protein that are critical for GTP and receptor binding. Indeed, we observed that the GTPase activity of the mutated proteins was impaired. ...

Dyskeratosis congenita (DC) is an inherited bone marrow failure syndrome characterized by the presence of short telomeres at presentation. Mutations in ten different genes, whose products are involved in the telomere maintenance pathway, have been shown to cause DC. The X-linked form is the most common form of the disease and is caused by mutations in the gene DKC1, encoding the protein dyskerin. Dyskerin is required for the assembly and stability of telomerase and is also involved in ribosomal...

Fanconi anaemia (FA) is a rare genetic disease resulting in impaired response to DNA damage. Although it is a very rare disorder, study of this and other bone marrow failure syndromes has improved scientific understanding of the mechanisms of normal bone marrow function and development of cancer. Among those affected, the majority develops cancer, most often acute myelogenous leukemia, and 90% develop bone marrow failure (the inability to produce blood cells) by age 40. About 60-75% of people have congenital defects, commonly short stature, abnormalities of the skin, arms, head, eyes, kidneys, and ears, and developmental disabilities. Around 75% of people have some form of endocrine problems, with varying degrees of severity. FA is the result of a genetic defect in a cluster of proteins responsible for DNA repair. Treatment with androgens and hematopoietic (blood cell) growth factors can help bone marrow failure temporarily, but the long-term treatment is bone marrow transplant if a donor is ...
Before receiving the transplant, patients undergo conditioning therapy, which includes chemotherapy and/or radiation, to prepare the body for the transplant. The goal of the conditioning therapy is to remove the diseased bone marrow cells to make space for the new healthy ones to grow. The conditioning therapy also suppresses the immune system so that the body doesnt reject the donors foreign stem cells. The transplant stem cells are infused into the blood through an IV.. It takes about two to four weeks for the new blood cells to grow - during this period, the immune system is still weak and the patient is highly susceptible to viral, bacterial, and fungal infections. Bone marrow failure disorders are often complicated to transplant, so patients, both old and young, benefit from care at a center highly experienced treating these disorders..

A lot of work is being done to find out why PNH happens. If you have PNH, your bone marrow may not be working normally. Some patients develop PNH after they have had treatment for a bone marrow disorder called aplastic anaemia (AA) which causes the bone marrow to produce fewer blood cells. You develop PNH when your bone marrow produces a gene called PIG-A. This genetic change (mutation) happens after birth which means you acquire PNH rather than inheriting it. The PIG-A gene causes your bone marrow to produce blood cells without a special protein known as the GPI anchor which protects normal blood cells against your own immune system. Without the GPI anchor, PNH blood cells are not protected against a series of complex reactions called "complement activation" which is part of your bodys normal immune response to help fight infections. It is this lack of protection which allows your immune system to destroy your PNH blood cells and results in haemolysis which is the main cause of the symptoms ...

Dr. Gelinas has worked on problems of gene structure and function for his entire career. At ISB he uses advanced RNA and protein profiling methods to identify biomarkers for diseases of the brain, heart, and lung. He also contributes to studies of the genetic basis of mental disorders such as Alzheimers Disease and bipolar disorder and bone marrow disorders such as Fanconi Anemia. Prior to coming to the ISB, in the biopharmaceutical industry, Dr. Gelinas and his group used systems tools to identify a chemical signal for inflammation and disease persistence common to rheumatoid arthritis, Crohns disease, and some other chronic conditions. An antibody therapeutic against this target (IL-6) is now advancing through human trials. He is optimistic that systems approaches can continue to improve medical diagnosis and speed the development of new therapeutics.. ...

Diamond Blackfan anemia (DBA) is a lineage-selective inherited bone marrow failure syndrome characterized primarily by anemia and physical malformations. Recent advances in identifying the genetic abnormalities underlying DBA have demonstrated involvement of genes encoding both large (RPL) and small (RPS) ribosomal subunit proteins, including mutations of RPL5, RPL11, RPL35A, RPS7, RPS10, RPS17, RPS19, RPS24, and RPS26 in 50% to 60% of affected patients. Despite significant progress, identification of gene abnormalities in the remaining patients remains an important question since present data suggest that mutations in other members of the ribosomal protein gene complement do not explain those cases without an identified genetic lesion in these genes. Genetic studies have also raised new questions with the recognition of substantial variability in the manifestations of DBA, ranging from ribosomal protein mutations in otherwise asymptomatic individuals to those with classic severe red blood cell ...
SDS poses a number of diagnostic challenges when it presents with severe neonatal respiratory distress. Firstly, although previously described [8], this presentation is rare. Secondly and very importantly, many of the cardinal symptoms such as steatorrhoea, failure to thrive and neutropenia may not be apparent soon after birth, or not be recognised unless the information is specifically sought. As many SDS patients have improvement in pancreatic function over time and the neutropenia fluctuates, the diagnosis may become more difficult to establish as the child develops. Thirdly, the characteristic chondrodysplasia often seen in this condition may well not become apparent until the second or third year of life. Thus, a child with neonatal respiratory distress consequent on severe thoracic dystrophy is much more likely to be diagnosed with a primary skeletal dysplasia, such as ATD, than with SDS. SDS is also largely managed by gastroenterologists and haematologists, rather than those who would ...
2017 Purpose To determine the relation of superolateral Hoffas fat pad (SHFP) hyperintensity to cartilage damage and bone marrow lesions (BMLs) in the patellofemoral joint (PFJ) and tibiofemoral joint (TFJ). Methods We used data from the 60 and 84-month study visits from the Multicenter Osteoarthritis (MOST) study. SHFP hyperintensity and Hoffa-synovitis were graded from 0 to 3. Cartilage damage and BMLs were scored in the PFJ and TFJ. Structural damage was defined as: any cartilage damage, full-thickness cartilage damage and any BML. Worsening structural damage was defined as any increase in cartilage and BML scores. Logistic regression was used to determine the relation of SHFP hyperintensity and Hoffa-synovitis (>0) to structural damage, adjusting for age, sex and body mass index (BMI). Results 1,094 knees were included in the study. Compared to knees without SHFP hyperintensity, those with SHFP hyperintensity had 1.2 (95% Confidence Interval (CI), 1.1-1.4), 1.7 (1.3-2.3) and 1.6 (1.3-1.9) ...
Bone marrow biopsy and bone marrow aspiration are procedures to collect and examine bone marrow - the spongy tissue inside some of your larger bones. Bone marrow biopsy and bone marrow aspiration can show whether your bone marrow is healthy and making normal amounts of blood cells. Doctors use bone marrow biopsy and aspiration to diagnose and monitor blood and marrow diseases, including some cancers.
The objective of this study was to investigate the relationship of cartilage loss and bone marrow lesions (BMLs) in the medial and lateral patellofemoral joint (PFJ) to knee pain. The location of full-thickness cartilage loss and BMLs in the PFJ on knee magnetic resonance imaging (MRIs) from the Multicenter Osteoarthritis (MOST) and Framingham Osteoarthritis (FOA) Studies were categorized as no damage, isolated medial, isolated lateral, or both medial and lateral (mixed). The relationship of MRI lesions in each PFJ region to prevalent knee pain were determined. Differences in knee pain severity were compared among categories of PFJ full-thickness cartilage loss and BMLs using quantile regression. In MOST (n=1137 knees), compared with knees without full-thickness cartilage loss, knees with isolated lateral or mixed PFJ full-thickness cartilage loss had 1.9 (1.3, 2.8) and 1.9 (1.2, 2.9) times the odds of knee pain, respectively, while isolated medial cartilage loss had no relationship to knee ...

  • Doubling the low amount of total body radiation delivered to patients undergoing bone marrow transplants with donor cells that are only "half-matched" increased the rate of engraftment from only about 50 percent to nearly 100 percent, according to a new study by Johns Hopkins researchers. (medicalxpress.com)
  • Bone marrow transplants are not just for patients with a perfectly matched donor. (medicalxpress.com)
  • In the late 1980s, explain study leaders Javier Bolaños-Meade, M.D., associate professor of oncology at the Johns Hopkins Kimmel Cancer Center, and Brodsky, researchers discovered that bone marrow transplants could potentially cure sickle cell disease , a condition with few effective treatments and one that typically kills patients in their 40s. (medicalxpress.com)
  • Since finding a full match is difficult in this patient population-fewer than 15 percent have fully matched siblings free of the same genetic defect that causes sickle cell disease, and less than a quarter have full matches in unrelated registries-Johns Hopkins researchers developed a protocol, published in 2012, that allows patients to receive transplants from relatives who are only half-matched. (medicalxpress.com)
  • Seeking to increase the odds of engraftment for these half-matches, Bolaños-Meade and his colleagues tested a new protocol for bone marrow transplants in patients with severe sickle cell disease and beta thalassemia, two related blood disorders known as hemoglobinopathies that are caused by defects in the same beta-globin gene. (medicalxpress.com)
  • After their transplants, all received a dose of cyclophosphamide, a drug that has proved critical to avoiding a potentially deadly condition known as graft versus host disease that is particularly prevalent with half-matches. (medicalxpress.com)
  • We have performed more than 1,000 half-matched bone marrow transplants, and our clinical studies have proved so successful, with safety and toxicity comparable to matched transplants, that half-identical transplants must be made available to more patients as a curative option. (medicalxpress.com)
  • Bone marrow is the traditional source of stem cells for both autologous and homologous transplants. (medscape.com)
  • On October 27, 2014, it was reported that Case Western Reserve University will conduct a preclinical study of PLX-R18 cells in umbilical cord blood transplants for the treatment of blood cancers and genetic diseases. (wikipedia.org)
  • ViroPharma Incorporated (Nasdaq: VPHM) announced the publication of results of its previously described Phase 2 study showing that maribavir, when used as prophylaxis, reduced the rate of cytomegalovirus (CMV) reactivation and was well tolerated when compared to placebo in allogeneic stem cell , or bone marrow , transplant patients. (medicalnewstoday.com)
  • Approximately 60 percent of all at-risk allogeneic stem cell (bone marrow) transplant patients will show evidence of CMV infection in the first 100 days post transplant and despite treatment with currently available therapies approximately 10 percent of these patients will progress to develop CMV disease, which may manifest as deadly complications such as pneumonia or gastrointestinal disease. (medicalnewstoday.com)
  • It is clear that maribavir has the potential to offer an important new and safer option for clinicians to prevent CMV disease in transplant patients. (medicalnewstoday.com)
  • While this dose-ranging study evaluated the safety and the ability of maribavir to prevent viral reactivation in bone marrow transplant patients, we are particularly encouraged by the possibility that maribavir may help reduce the rate of CMV disease and associated morbidity, something we are investigating in our current Phase 3 study," said Stephen Villano, M.D., vice president, clinical research and development at ViroPharma. (medicalnewstoday.com)
  • In about one third of patients, the disease transforms into an acute form of leukemia. (insideedition.com)
  • Dr. Abdel-Wahab's laboratory expressed a spliceosomal gene mutation in the Srsf2 gene, a mutation common in MDS and AML patients, in the bone marrow cells of a leukemia mouse model. (army.mil)
  • The mice expressing both mutant and wildtype Srsf2 rapidly developed fatal bone marrow failure and eventually developed leukemia. (army.mil)
  • This is likely due to the decreased survival of leukemia-promoting bone marrow cells expressing mutant Srsf2 in the absence of wildtype Srsf2 expression. (army.mil)
  • Similar associations were already documented in case reports and case series, but have never been evaluated in a broad spectrum of autoimmune diseases in that many patients and in context of individual medications," says Raoul Tibes, M.D., Ph.D., senior author of the study and former director of the Acute and Chronic Leukemia Program at Mayo Clinic's Arizona campus. (eurekalert.org)
  • The diagnostic significance of tumor infiltrates topography and basicrules of the differential diagnoses of malignant lymphomas in the bone marrow biopsies arediscussed. (prolekare.cz)
  • Standard treatments aimed at suppressing or modulating the immune response are often ineffective in managing diseases like IBD and GVHD. (seattlechildrens.org)
  • The researchers turned their attention to GVHD because it's an important medical problem and also because in animal models, disease-causing cells can easily be distinguished from normal cells. (cbslocal.com)
  • Bz-423 provides a much higher level of selectivity for silencing disease-causing cells than is seen with the immunosuppressive drugs typically used for diseases like GVHD," Glick said. (cbslocal.com)
  • In the experiments described in the paper, Bz-423 arrested GVHD in mice by selectively killing disease-causing T cells, with no adverse effects on normal cells or bone marrow transplant success. (cbslocal.com)
  • The incidence of acute graft-versus-host disease (GVHD) is similar with the two methods. (medscape.com)
  • There are no preventive treatments, but steroids are often prescribed to reduce the diseases' pain and inflammation. (futurity.org)
  • In both diseases, there is a need for new, targeted therapies able to prevent or treat the diseases without causing the side effects that plague current treatments. (seattlechildrens.org)
  • Researchers analyzed more than 40,000 patient cases with 27 common autoimmune diseases, such as Lupus, rheumatoid arthritis, among others, that were seen over a decade at Mayo Clinic. (eurekalert.org)
  • Many different autoimmune diseases were analyzed, which can each affect the results. (eurekalert.org)
  • Watching a young patient suffer through the pain of severe colitis bolstered Fraker's need to research this devastating disease. (futurity.org)

  • A characteristic skeletal phenotype is one of the many clinical manifestations in Hurler disease. (sigmaaldrich.com)
  • A number of clinical trials have proved the superiority of this method over collection from the bone marrow. (medscape.com)
  • When colitis was induced in mice, she was surprised by the significant and swift changes that occurred in their bone marrow. (futurity.org)
  • Bone marrow disease is found to be a very rare illness that attacks human beings. (wittyfeed.com)
