Removal of bone marrow and evaluation of its histologic picture.
Deficiency of all three cell elements of the blood, erythrocytes, leukocytes and platelets.
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.
Suppression of erythropoiesis with little or no abnormality of leukocyte or platelet production.
A group of related disorders characterized by LYMPHOCYTOSIS; HISTIOCYTOSIS; and hemophagocytosis. The two major forms are familial and reactive.
Cells contained in the bone marrow including fat cells (see ADIPOCYTES); STROMAL CELLS; MEGAKARYOCYTES; and the immediate precursors of most blood cells.
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.
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.
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 diseases are disorders that affect the production of blood cells in the bone marrow.

Prognostic significance of bone marrow biopsy in essential thrombocythemia. (1/338)

BACKGROUND AND OBJECTIVE: The diagnostic and prognostic value of bone marrow biopsy (BMB) has been widely investigated in patients with chronic myeloproliferative disorders (CMPD). The present study is based on a review of the results of routine BMBs taken from 93 essential thrombocythemia (ET) patients at the time of diagnosis. DESIGN AND METHODS: The common BMB histologic parameters and clinico-hematologic variables were considered for diagnostic and prognostic purposes. Clinico-pathologic correlations were looked for univariately. Moreover, the diagnostic significance of the histologic findings was tested by means of cluster analysis. Overall survival and event-free survival were considered as prognostic endpoints. RESULTS: There were no correlations between the clinic and pathologic findings, and none of the histologic and clinical parameters was predictive of survival or the occurrence of major clinical events. Cluster analysis of the BMB findings revealed two distinct morphologic patterns: one was clearly myeloproliferative; the other had somewhat dysplastic features. The event-free and overall survival rates in the latter group were significantly worse (p = 0.0377 and p = 0.0162 respectively), with major ischemic events accounting for most of the difference in event-free survival. INTERPRETATION AND CONCLUSIONS: These results have no clearcut counterpart in the literature, but we feel that dysplastic BMB findings could be included in the definition of ET prognostic scores in order to allow therapeutic strategies to be adapted to the level of risk.  (+info)

Plasmablastic morphology is an independent predictor of poor survival after autologous stem-cell transplantation for multiple myeloma. (2/338)

PURPOSE: To study the prognostic value of plasmablastic morphology after autologous stem-cell transplantation for relapsed or primary refractory myeloma. PATIENTS AND METHODS: Seventy-five patients were studied. Investigators blinded to the clinical details of the individual cases reviewed bone marrow aspirate slides to determine plasmablastic classification. Plasmablasts were defined using strict, well-described criteria. Plasmablastic morphology was considered to be present (plasmablastic myeloma) when 2% or more plasmablasts were present in the plasma-cell population. RESULTS: Patients underwent transplantation 5 to 88 months (median, 20 months) after the initial diagnosis of myeloma. Twenty-eight percent of patients had plasmablostic morphology. A significantly greater proportion of patients with plasmablastic morphology had abnormal cytogenetics compared with those with nonplasmablastic classification (73% v 31%, respectively; P = .003). The overall survival rate measured from the time of transplantation was significantly worse in patients with plasmablastic morphology compared with those without (median survival time, 5 months v 24 months, respectively; P < .001). Progression-free survival time was shortened also, with a median time of 4 months compared with 12 months, respectively (P < .001). In the multivariate analysis, plasmablastic classification was the most powerful prognostic factor after transplantation for both overall (P = .001) and progression-free survival rates (P < .001). We also identified three risk groups based on plasmablastic morphology: plasma-cell labeling index, lactate dehydrogenase, and cytogenetics. The median overall survival time was 38 months when none of these factors was abnormal, 17 months with one abnormal factor, and 8 months with two or more abnormal factors (P < .001). CONCLUSION: Plasmablastic morphology is a powerful independent predictor of poor survival rate after autologous stem-cell transplantation for relapsed or primary refractory myeloma.  (+info)

Long-term toxicity of modified recombinant human tumor necrosis factor in Macaca mulatta. (3/338)

AIM: To study the long-term toxicity of modified recombinant human tumor necrosis factor (rhTNF-NC) in Macaca mulatta compared with recombinant human tumor necrosis factor (rhTNF). METHODS: rhTNF-NC 93, 9.3 GU/m2, and rhTNF 62 GU/m2 were injected i.v. daily to 16 Macaca mulatta for 1 month and 10 d, respectively. Hematologic, chemical, urinalysis values, ECG, specific antibody, bone marrow, and pathologic profile of organs were measured. RESULTS: No more adverse effects of rhTNF-NC were found in spite of anorexia in 4 monkeys and palpebral edema in 2 monkeys of 93 GU/m2 group. Besides, in rhTNF group, the injury of liver and kidneys, the decrease of erythron, the phlebitis, and thrombosis at injection site occurred. Both drugs caused the production of specific antibody. CONCLUSION: No serious adverse effects of rhTNF-NC were found in Macaca mulatta. The toxicity of rhTNF-NC was much lower than that of rhTNF.  (+info)

Focal lymphoid aggregates (nodules) in bone marrow biopsies: differentiation between benign hyperplasia and malignant lymphoma--a practical guideline. (4/338)

AIMS: To provide practical guidelines for the differentiation between benign and malignant focal lymphoid aggregates (lymphoid nodules) in routinely referred bone marrow trephine biopsies, using a synoptic approach including clinical data and histological workup. METHODS: For easy identification of very small lymphoid infiltrates the chloroacetate esterase stain was applied as a screening procedure. This allowed the identification of 491 formalin fixed, paraffin wax embedded specimens with one or more lymphoid nodules. Examination of lymphoid infiltrates included such variables as histotopography, demarcation, cytology, reticulin fibres, and immunohistochemistry with a set of monoclonal antibodies (CD20, CD45R, CD45R0, CD3, CD43). Evaluation of clinical and morphological data was carried out independently. In case of malignant lymphomas, a correlation with corresponding lymph node findings was made. RESULTS: 352 patients had benign focal lymphoid aggregates usually associated with systemic autoimmune diseases, chronic myeloproliferative disorders, toxic myelopathy, and viral infections. Discrete nodular infiltrates of (small cell) malignant lymphomas (n = 93) simulating benign hyperplasia were found in chronic lymphocytic leukaemia, germinal centre cell lymphomas (CB-CC), and lymphoplasmacytic/cytoid lymphomas (LPI). In addition to immunoreactivity, certain histological variables proved distinctive. These were: (1) histotopography, that is, localisation of the lymphoid aggregates within the bone marrow space; (2) relation to the surrounding tissue: margination or interstitial spillage of lymphoid cells; and (3) increase in reticulin fibres. CONCLUSIONS: A combined diagnostic procedure identifying several distinctive features, in particular histotopography and immunohistochemistry, provides a most promising way of discriminating reactive from neoplastic lymphoid nodules in the bone marrow.  (+info)

Dibromomannitol in the treatment of chronic granulocytic leukemia: a prospective randomized comparison with busulfan. (5/338)

Dibromomannitol (DBM) is a new agent for the treatment of chronic granulocytic leukemia. A propsective evaluation of the drug was undertaken in a randomized comparison with busulfan. Forty previously untreated, Philadelphia chromosome-positive cases were treated, with 20 patients in each treatment group. The protocol provided for continuous maintenance therapy after remission induction, with a crossover to the opposite drug in patients who became refractory to the primary agent but are without evidence of blastic tranformation. There were 14 remissions in the DBM group and 15 in those treated with busulfan. The rate of decrease of the elevated leukocyte count was more rapid with DBM, but prolonged disease control off treatment occurred in only three of 14 cases as opposed to nine of fifteen busulfan-treated patients who required a median delay of 12 mo before maintenance could be initiated. Hypoplasia occurred in one DBM patient and two busulfan cases. Following recovery, crossover to the opposite drug in two cases again resulted in hypopllasia. Increased skin pigmentation, amenorrhea, pulmonary fibrosis, and cytologic dysplasia, commonly associated with busulfan adminstration, were also noted with DBM. The median duration of disease control with busulfan was 34 mo and 26 mo with DBM. There was no signigicant difference in the incidence of blastic transformation, and median survival for both groups was 44 mo. DBM appears to be as effective as busulfan in the treatment of the chronic phase of CGL but with a more predictable myelosuppressive action. The principal advantage of busulfan over DBM is the fact that more than half the busulfan-treated patients experienced prolonged disease control off treatment.  (+info)

De novo appearance of the ph-1 chromosome in a previously monosomic bone marrow (45,XX,-6): conversion of a myeloproliferative disorder to acute myelogenous leukemia. (6/338)

Bone marrow examination of a patient with a myeloproliferative disorder revealed monosomy for chromosome No. 6 (45,XX,-6). Two months later, during blastic crisis, reinvestigation of the bone marrow showed the presence of the Ph-1 chromosome in the previously aneuploid cell line (45,XX,-6,-22,+Ph-1). This case differs from those previously published in that the Ph-1 chromosome appeared de novo during the development of frank acute myelogenous leukemia.  (+info)

Functional and morphologic characteristics of the leukemic cells of a patient with acute monocytic leukemia: correlation with clinical features. (7/338)

The clinical course of a patient with acute monocytic leukemia and prominent infiltration of the skin and testes is described. In vitro studies demonstrated that the circulating monocyte precursors were capable of adherence to nylon fibers, and phagocytosis of bacteria and latex particles. In vivo, migration of leukemic cells to skin windows was observed. Extreme nuclear folding, marked surface activity, and morphologic features suggesting nuclear and cytoplasmic maturation were seen by light and electron microscopy. The presence of morphologically and functionally more differentiated monocytic cells may account for the marked tiuuse invasion in this patient and, possibly, in other patients with monocytic leukemia.  (+info)

Antitumor activity of thalidomide in refractory multiple myeloma. (8/338)

BACKGROUND: Patients with myeloma who relapse after high-dose chemotherapy have few therapeutic options. Since increased bone marrow vascularity imparts a poor prognosis in myeloma, we evaluated the efficacy of thalidomide, which has antiangiogenic properties, in patients with refractory disease. METHODS: Eighty-four previously treated patients with refractory myeloma (76 with a relapse after high-dose chemotherapy) received oral thalidomide as a single agent for a median of 80 days (range, 2 to 465). The starting dose was 200 mg daily, and the dose was increased by 200 mg every two weeks until it reached 800 mg per day. Response was assessed on the basis of a reduction of the myeloma protein in serum or Bence Jones protein in urine that lasted for at least six weeks. RESULTS: The serum or urine levels of paraprotein were reduced by at least 90 percent in eight patients (two had a complete remission), at least 75 percent in six patients, at least 50 percent in seven patients, and at least 25 percent in six patients, for a total rate of response of 32 percent. Reductions in the paraprotein levels were apparent within two months in 78 percent of the patients with a response and were associated with decreased numbers of plasma cells in bone marrow and increased hemoglobin levels. The microvascular density of bone marrow did not change significantly in patients with a response. At least one third of the patients had mild or moderate constipation, weakness or fatigue, or somnolence. More severe adverse effects were infrequent (occurring in less than 10 percent of patients), and hematologic effects were rare. As of the most recent follow-up, 36 patients had died (30 with no response and 6 with a response). After 12 months of follow-up, Kaplan-Meier estimates of the mean (+/-SE) rates of event-free survival and overall survival for all patients were 22+/-5 percent and 58+/-5 percent, respectively. CONCLUSIONS: Thalidomide is active against advanced myeloma. It can induce marked and durable responses in some patients with multiple myeloma, including those who relapse after high-dose chemotherapy.  (+info)

Bone marrow examination is a medical test that involves removing a sample of bone marrow from a patient's bone and examining it under a microscope. The bone marrow is the soft, spongy tissue found inside the bones, and it is responsible for producing blood cells, including red blood cells, white blood cells, and platelets. There are several different types of bone marrow examinations, including aspiration, biopsy, and trephination. During an aspiration, a small amount of bone marrow is removed using a needle and syringe. During a biopsy, a larger sample of bone marrow is removed using a biopsy needle. During trephination, a small piece of bone is removed, along with the bone marrow. Bone marrow examination is used to diagnose a variety of medical conditions, including anemia, leukemia, lymphoma, and multiple myeloma. It can also be used to monitor the effectiveness of treatment for these conditions, and to detect any complications that may arise during treatment.

Pancytopenia is a medical condition characterized by a decrease in all three types of blood cells: red blood cells (anemia), white blood cells (leukopenia), and platelets (thrombocytopenia). This can lead to a variety of symptoms, including fatigue, weakness, shortness of breath, bruising, and an increased risk of infections. Pancytopenia can be caused by a variety of factors, including bone marrow disorders, exposure to toxins, certain medications, and autoimmune diseases. Treatment for pancytopenia depends on the underlying cause and may include medications, blood transfusions, or bone marrow transplantation.

Bone marrow is a soft, spongy tissue found inside the bones of most mammals, including humans. It is responsible for producing blood cells, including red blood cells, white blood cells, and platelets. Red blood cells are responsible for carrying oxygen throughout the body, white blood cells help fight infections and diseases, and platelets are involved in blood clotting. The bone marrow is divided into two main types: red bone marrow and yellow bone marrow. Red bone marrow is responsible for producing all types of blood cells, while yellow bone marrow is primarily responsible for producing fat cells. In some cases, the bone marrow can be damaged or diseased, leading to conditions such as leukemia, lymphoma, or aplastic anemia. In these cases, bone marrow transplantation may be necessary to replace damaged or diseased bone marrow with healthy bone marrow from a donor.

Red-cell aplasia, pure, is a medical condition characterized by a decrease in the production of red blood cells (erythrocytes) in the bone marrow. In this condition, the bone marrow fails to produce enough red blood cells to meet the body's oxygen-carrying needs, leading to anemia. Pure red-cell aplasia is different from other forms of anemia because it affects only the production of red blood cells, while other forms of anemia may also involve a decrease in the production of white blood cells or platelets. The cause of pure red-cell aplasia can be idiopathic (unknown), or it may be associated with certain medical conditions, such as autoimmune disorders, infections, or exposure to certain medications or toxins. Symptoms of pure red-cell aplasia may include fatigue, weakness, shortness of breath, and pale skin. Treatment for pure red-cell aplasia typically involves administering red blood cell transfusions to replace the deficient red blood cells, as well as addressing any underlying medical conditions that may be contributing to the condition. In some cases, immunosuppressive therapy may be used to suppress the immune system and promote the production of red blood cells in the bone marrow.

Lymphohistiocytosis, hemophagocytic (LCH) is a rare disorder characterized by the accumulation of abnormal immune cells called histiocytes and lymphocytes in various tissues of the body. These cells can cause inflammation and damage to organs such as the liver, spleen, bone marrow, and central nervous system. One of the hallmark features of LCH is the presence of hemophagocytosis, which is the consumption of normal blood cells by the abnormal immune cells. This can lead to anemia, low platelet counts, and other complications. LCH can occur in both children and adults, and its symptoms can vary widely depending on the affected organs and the severity of the disease. Some common symptoms include fever, fatigue, weight loss, and swollen lymph nodes. There are several different types of LCH, including Letterer-Siwe disease (LS), Hand-Schüller-Christian disease (HSC), and eosinophilic granuloma complex (EGC). Treatment for LCH typically involves a combination of medications, such as corticosteroids, chemotherapy, and targeted therapies, depending on the type and severity of the disease.

Bone marrow cells are the cells found in the bone marrow, which is the soft, spongy tissue found in the center of bones. These cells are responsible for producing blood cells, including red blood cells, white blood cells, and platelets. There are two types of bone marrow cells: hematopoietic stem cells and progenitor cells. Hematopoietic stem cells are capable of dividing and differentiating into any type of blood cell, while progenitor cells are capable of dividing and differentiating into specific types of blood cells. In the medical field, bone marrow cells are often used in the treatment of blood disorders, such as leukemia and lymphoma, as well as in the transplantation of bone marrow to replace damaged or diseased bone marrow. In some cases, bone marrow cells may also be used in research to study the development and function of blood cells.

Bone marrow transplantation (BMT) is a medical procedure in which healthy bone marrow is transplanted into a patient who has damaged or diseased bone marrow. The bone marrow is the spongy tissue found inside bones that produces blood cells, including red blood cells, white blood cells, and platelets. There are two main types of bone marrow transplantation: autologous and allogeneic. Autologous BMT involves transplanting bone marrow from the patient's own body, usually after it has been harvested and stored before the patient undergoes high-dose chemotherapy or radiation therapy to destroy their diseased bone marrow. Allogeneic BMT involves transplanting bone marrow from a donor who is a genetic match for the patient. BMT is used to treat a variety of conditions, including leukemia, lymphoma, multiple myeloma, sickle cell anemia, and some inherited blood disorders. The procedure can also be used to treat certain immune system disorders and some genetic diseases. The success of BMT depends on several factors, including the type and stage of the patient's disease, the patient's overall health, and the availability of a suitable donor. The procedure can be complex and may involve several stages, including preparatory treatment, the actual transplantation, and post-transplantation care.

In the medical field, "bone and bones" typically refers to the skeletal system, which is made up of bones, cartilage, ligaments, tendons, and other connective tissues. The skeletal system provides support and structure to the body, protects vital organs, and allows for movement through the use of muscles. Bones are the main component of the skeletal system and are responsible for providing support and protection to the body. There are 206 bones in the human body, which are classified into four types: long bones, short bones, flat bones, and irregular bones. Long bones, such as the femur and humerus, are cylindrical in shape and are found in the arms and legs. Short bones, such as the carpals and tarsals, are cube-shaped and are found in the wrists and ankles. Flat bones, such as the skull and ribs, are thin and flat and provide protection to vital organs. Irregular bones, such as the vertebrae and pelvis, have complex shapes that allow for specific functions. Overall, the bone and bones of the skeletal system play a crucial role in maintaining the health and function of the human body.

Bone remodeling is a continuous process that occurs in the human body to maintain the strength and integrity of bones. It involves the coordinated activity of bone-forming cells called osteoblasts and bone-resorbing cells called osteoclasts. During bone remodeling, osteoclasts break down old or damaged bone tissue, releasing minerals and other components into the bloodstream. Osteoblasts then lay down new bone tissue to replace the old bone that was removed. This process of bone resorption followed by bone formation is a dynamic equilibrium that helps to maintain the balance between bone strength and bone density. Bone remodeling is influenced by a variety of factors, including hormones, mechanical stress, and age. For example, during childhood and adolescence, bone remodeling is stimulated by growth hormones and physical activity, leading to increased bone density and strength. In older adults, bone remodeling slows down, leading to a decrease in bone density and an increased risk of fractures. Disruptions in the bone remodeling process can lead to a variety of bone disorders, including osteoporosis, osteogenesis imperfecta, and Paget's disease. Understanding the mechanisms of bone remodeling is important for developing effective treatments for these conditions.

Bone marrow diseases refer to a group of disorders that affect the bone marrow, which is the spongy tissue inside bones that produces blood cells. The bone marrow produces red blood cells, white blood cells, and platelets, which are essential for the proper functioning of the immune system, oxygen transport, and blood clotting, respectively. There are several types of bone marrow diseases, including: 1. Leukemia: A type of cancer that affects the bone marrow and blood cells. It is characterized by the uncontrolled growth and division of abnormal white blood cells. 2. Lymphoma: A type of cancer that affects the lymphatic system, which is part of the immune system. It can also affect the bone marrow and produce abnormal white blood cells. 3. Myelodysplastic syndromes (MDS): A group of disorders that affect the bone marrow's ability to produce healthy blood cells. MDS can progress to leukemia. 4. Multiple myeloma: A type of cancer that affects plasma cells, which are a type of white blood cell that produces antibodies. It is characterized by the overproduction of abnormal plasma cells in the bone marrow. 5. Polycythemia vera: A type of blood disorder that causes the bone marrow to produce too many red blood cells. 6. Thalassemia: A group of genetic disorders that affect the production of hemoglobin, a protein found in red blood cells that carries oxygen throughout the body. Treatment for bone marrow diseases depends on the specific type and severity of the disorder. It may include chemotherapy, radiation therapy, stem cell transplantation, or supportive care to manage symptoms and complications.
