    Khan, A.G.; Irfan, M.; Shamsi, T.S.; Hussain, M.

    2007-01-01

    To identify the psychiatric illnesses in patients with hematological/oncological disorders encountered during blood and bone marrow transplantation. All consecutive patients, aged 15 years and above, who fulfilled inclusion and exclusion criteria and underwent blood and bone marrow transplantation, were enrolled in this study. Psychiatric assessment comprised of a semi-structured interview based on Present Status Examination (PSE). The psychiatric diagnosis was made on the basis of International Classification of Diseases (ICD-10) system of classification devised by W.H.O. Eighty patients, who fulfilled the inclusion criteria, were inducted in this study. Thirty (37.5%) cases were found to have psychiatric disorders. Out of the total, 60 (75%) were males and 20 (25%) females. Adjustment disorder was the most frequent diagnosis (n=12), followed by major depression (n=7). Rest of the diagnoses made were generalized anxiety disorder, acute psychotic disorder, delirium and depressive psychosis. High psychiatric morbidity associated with blood and bone marrow transplantation was observed. It indicates the importance of psychiatric intervention during the isolation period of BMT as well as pre-transplant psychiatric assessment and counseling regarding procedure. (author)

  2. Bone marrow transplantation in patients with Thalassemia

    Full Text Available During April, 1991 and September, 1993, eighteen patients with major thalassemia admitted to Shariati BMT center. Seventeen patients were transplanted were from HLA identical siblings and one from. his HLA identical father. Eleven of the donors were the known cases of minor thalassemia. The range of patients' age was within 3-10 years (with the average of 5 years and 11 months. Among them, seven patients were male and eleven were female. As the other international BMT centers, we classified our patients into three classes. Our criteria for this classification were hepatomegaly, ferretin, and liver fibrous; 60% of our patients were put in class I and 40% in class II. All of our patients revealed a GVHD (severe graft vs. host disease three weeks post-BMT as pruritus, diarrhea, and skin erythema especially in hands and feet. Two of the patients showed severe GVHD. One of the patients had chimerism after BMT. Although one year after BMT has passed, the patients is still depended on blood transfusion. One patient, despite graft rejection, died nine months post-BMT; another one died after +70 due to GVHD. During 2.5 years, the overall graft survival rate was 88% in our center

  3. The Bone Marrow Transplantation Center of the National Cancer Institute - its resources to assist patients with bone marrow failure

    Tabak, Daniel

    1997-01-01

    This paper describes the bone marrow transplantation center of the brazilian National Cancer Institute, which is responsible for the cancer control in Brazil. The document also describes the resources available in the Institute for assisting patients presenting bone marrow failures. The Center provides for allogeneic and autologous bone marrow transplants, peripheral stem cell transplants, umbilical cord collections and transplants, and a small experience with unrelated bone marrow transplants. The Center receives patient from all over the country and provides very sophisticated medical care at no direct cost to the patients

  4. Bone marrow transplantation for patients with chronic myeloid leukemia

    Goldman, J.M.; Apperley, J.F.; Jones, L.

    1986-01-01

    Between February 1981 and December 1984 we treated 52 patients with chronic myeloid leukemia in the chronic phase and 18 patients with more advanced disease by high-dose chemoradiotherapy followed by allogeneic bone marrow transplantation using marrow cells from HLA-identical sibling donors. In addition, the 40 patients who had not previously undergone splenectomy received radiotherapy to the spleen. To prevent graft versus host disease, cyclosporine was given either alone or in conjunction with donor marrow depleted of T cells. Of the 52 patients treated in the chronic phase, 38 are alive after a median follow-up of 25 months (range, 7 to 50); the actuarial survival at two years was 72%, and the actuarial risk of relapse was 7%. Of the 18 patients with more advanced disease, 4 have survived; the actuarial two-year survival was 18%, and the actuarial risk of relapse was 42%. We conclude that the probability of cure is highest if transplantation is performed while the patient remains in the chronic phase of chronic myeloid leukemia. T-cell depletion may have reduced the incidence and severity of graft versus host disease. The value of irradiation to the spleen before transplantation has not been established

  5. Bone-marrow MR imaging before and after autologous marrow transplantation in lymphoma patients without known bone-marrow involvement

    Lien, H.H.; Blomlie, V.; Blystad, A.K.; Holte, H.; Kvaloey, S.; Langholm, R.

    1997-01-01

    Purpose: To study lumbar bone marrow by means of MR imaging before and after bone-marrow transplantation in lymphoma patients. Particular emphasis was paid to heterogeneity and to focal manifestations, i.e. appearances that could simulate tumor. Material and Methods: Twenty-two patients who were disease-free for a minimum of 30 months after transplantation were studied in 107 MR examinations. Two radiologists visually evaluated coronal T1-weighted and short inversion time inversion-recovery (STIR) images. Results: T1-weighted images demonstrated a more heterogeneous marrow after transplantation than before it. Sharply defined focal low signal intensity areas appeared on this sequence in 5 (23%) of the 22 patients at between 21 and 60 weeks after transplantation. The mean age of these 5 patients was 48.4 years (range 42-54 years). The difference in age between these 5 patients and the remaining 17 patients, who had a mean age of 33.4 years (range 14-51 years), was statistically significant (p<0.01, Student's t-test, 2-sided test). Conclusion: Sharply defined focal low signal intensity areas may be seen on T1-weighted images of bone marrow in patients who are in complete remission after transplantation, particularly in those aged over 40-45 years.

  6. Bone marrow transplantation

    Storb, R.; Santos, G.W.

    1979-01-01

    Bone marrow transplantation has been increasingly used to treat patients with severe combined immunodeficiency diseases, severe aplastic anemia, and malignant hematologic diseases, especially leukemia. At the Workshop a number of problems were discussed, e.g., conditioning regimens aimed at overcoming the problem of marrow graft rejection and reducing the incidence of recurrent leukemia, prevention of graft-versus-host disease (GVHD), possible mechanisms involved in stable graft-host tolerance, graft-versus-leukemia effect in mice, and finally, the possible use of autologous marrow transplantation

  7. Overview of marrow transplantation

    Thomas, E.D.

    1985-01-01

    Bone marrow transplantation is now an accepted form of therapy for many hematologic disorders including aplastic anemia, genetically determined diseases and malignant diseases, particularly leukemia, and for rescue of patients given intensive chemoradiotherapy for malignant disease. The donor may be a healthy identical twin, a family member or even an unrelated person. Selection is made on the basis of human leukocyte antigen tissue typing. Intensive chemoradiotherapy is used to suppress patients' immune systems to facilitate engraftment and destroy diseased marrow. Transfusion of platelets, erythrocytes and granulocytes (or all of these), antibiotic coverage and protection from infection are necessary during the pancytopenic period. Survival rates vary considerably depending on a patient's disease, clinical state and age. Patients with aplastic anemia transplanted early in the course of their disease have a survival rate of approximately 80%. Patients with acute lymphoblastic leukemia are usually transplanted in a second or subsequent remission and have a survival rate of 25% to 40%. Patients with acute nonlymphoblastic leukemia in remission have survivals ranging from 45% to 70%. More than 200 patients in the chronic phase of chronic granulocytic leukemia have been transplanted with survival ranging from 50% to 70%. Complications of marrow transplantation include marrow graft rejection, graft-versus-host disease, immunologic insufficiency and the possibility of recurrence of the leukemia. 14 references

  10. Cytomegalovirus infection in the bone marrow transplant patient.

    Bhat, Vivek; Joshi, Amit; Sarode, Rahul; Chavan, Preeti

    2015-12-24

    Cytomegalovirus (CMV) infection is an important contributor to the morbidity and mortality associated with bone marrow transplantation (BMT). Infection may lead to CMV disease involving multiple organs such as pneumonia, gastroenteritis, retinitis, central nervus system involvement and others. CMV seropositivity is an important risk factor and approximately half of BMT recipients will develop clinically significant infection most commonly in the first 100 d post-transplant. The commonly used tests to diagnose CMV infection in these patients include the pp65 antigenemia test and the CMV DNA polymerase chain reaction (PCR) assay. Because of its greater sensitivity and lesser turnaround time, the CMV PCR is nowadays the preferred test and serves as a main guide for pre-emptive therapy. Methods of CMV prevention include use of blood products from seronegative donors or leukodepleted products. Prophylaxis or pre-emptive therapy strategies for CMV prevention may be used post-transplant with the latter becoming more common. The commonly used antivirals for pre-emptive therapy and CMV disease management include intravenous gancyclovir and foscarnet. The role of intravenous immunoglobulin, although used commonly in CMV pneumonia is not clear.

    A report is presented on the first results of transplantation of autologous bone marrow in 3 adult patients with acute myelogenous leukaemia. The treatment consisted of intensive chemotherapy and whole-body irradiation and was followed by transplantation of a limited number of non-purified bone-marrow cells that had previously been collected from the patient. In all three patients, transplantation was followed by a stable remission. One patient had a fatal recurrence after a total period of 21 months of remission. In 2 patients, the remissions continue. The clinical significance of these findings is discussed.

  13. Molecular relapse in chronic myelogenous leukemia patients after bone marrow transplantation detected by polymerase chain reaction

    Sawyers, C.L.; Timson, L.; Clark, S.S.; Witte, O.N.; Champlin, R.; Kawasaki, E.S.

    1990-01-01

    Relapse of chronic myelogenous leukemia after bone marrow transplantation can be detected by using clinical, cytogenetic, or molecular tools. A modification of the polymerase chain reaction can be used in patients to detect low levels of the BCR-ABL-encoded mRNA transcript, a specific marker for chronic myelogenous leukemia. Early detection of relapse after bone marrow transplantation could potentially alter treatment decisions. The authors prospectively evaluated 19 patients for evidence of molecular relapse, cytogenetic relapse, and clinical relapse after bone marrow transplantation. They used the polymerase chain reaction to detect residual BCR-ABL mRNA in patients followed up to 45 months after treatment and found 4 patients with BCR-ABL mRNA expression following bone marrow transplantation. Fifteen patients did not express detectable BCR-ABL mRNA. All 19 patients remain in clinical remission. In this prospective study of chronic myelogenous leukemia patients treated with bone marrow transplantation, molecular relapse preceded cytogenetic relapse in those patients who persistently express BCR-ABL mRNA. They recommend using standard clinical and cytogenetic testing to make patient care decisions until further follow-up determines the clinical outcome of those patients with residual BCR-ABL mRNA transcripts detected by polymerase chain reaction

    Haemopoietic stem cell transplantation (HSCT) is an important intervention for malignant and non-malignant blood diseases. However, HSCT is also associated with considerable morbidity and mortality, some of which may be related to iron overload. Levels of serum iron are elevated in patients

  17. Busulfan and total body irradiation as antihematopoietic stem cell agents in the preparation of patients with congenital bone marrow disorders for allogenic bone marrow transplantation

    Parkman, R.; Rappeport, J.M.; Hellman, S.; Lipton, J.; Smith, B.; Geha, R.; Nathan, D.G.

    1984-01-01

    The capacity of busulfan and total body irradiation to ablate hematopoietic stem cells as preparation for the allogeneic bone marrow transplantation of patients with congenital bone marrow disorders was studied. Fourteen patients received 18 transplants; busulfan was used in the preparatory regimen of eight transplants and total body irradiation in the regimens of six transplants. Sustained hematopoietic ablation was achieved in six of eight patients prepared with busulfan and in all six patients prepared with total body irradiation. Three patients prepared with total body irradiation died with idiopathic interstitial pneumonitis, whereas no patients receiving busulfan developed interstitial pneumonitis. The optimal antihematopoietic stem cell agent to be used for the preparation of patients with congenital bone marrow disorder for bone marrow transplantation is not certain

  18. One hundred patients with acute leukemia treated by chemotherapy, total body irradiation, and allogeneic marrow transplantation

    Thomas, E.D.; Buckner, C.D.; Banaji, M.

    1977-01-01

    One hundred patients, 54 with acute myelogenous leukemia (AML) and 46 with acute lymphoblastic leukemia (ALL), considered to be in the end stages of their disease, after combination chemotherapy were treated by marrow transplantation. All patients were given a marrow graft from an HLA-identical sibling after receiving 1000-rad total body irradiation (TBI). One group of 43 patients was given cyclophosphamide (CY), 60 mg/kg on each of 2 days, 5 and 4 days before TBI. In a second group of 31 patients, additional chemotherapy was given before CY and TBI. In a third group of 19 patients, BCNU was given before CY and TBI. A fourth group of 7 patients received other chemotherapy regimens before TBI. Six patients died 3 to 17 days after marrow infusion without evidence of engraftment. Ninety-four patients were engrafted rejected and only one patient rejected the graft. Thirteen patients are alive with a marrow graft, on no maintenance antileukemic therapy, and without recurrent leukemia 1--4 1 / 2 yr after transplantation. Three have chronic graft-versus-host disease (GVHD). The relapse rate appeared to be relatively constant over the first 2 yr and was extremely low after that time. Neither survival nor leukemic relapse appeared to be influenced by the type of leukemia nor by the preparative chemotherapy regimen given before TBI. Patients in fair clinical condition at the time of transplantation showed significantly longer survival times than patients in poor condition (p = 0.001). This observation, coupled with the observation that some patients may be cured of their disease, indicates that marrow transplantation should now be undertaken earlier in the management of patients with acute leukemia who have an HLA-matched sibling marrow donor

    Full Text Available We report two cases of fatal hepatic failure in patients who received matched unrelated bone marrow transplantation. Both patients presented with high fevers, abnormal liver functions tests, and hypodense lesions in the liver by CT scan. Histologic examination of postmortem liver samples demonstrated extensive necrosis, and immunohistochemistry was positive for adenovirus.

  20. Hyperfractionated total body irradiation for bone marrow transplantation. Results in seventy leukemia patients with allogeneic transplants

    Shank, B.; Chu, F.C.H.; Dinsmore, R.

    1983-01-01

    From May, 1979 to March, 1981, 76 leukemia patients were prepared for bone marrow transplantation (BMT) with a new hyperfractionated total body irradiation (TBI) regimen (1320 cGy in 11 fractions, 3x/day), followed by cyclophosphamide, 60 mg/kg, for two days. Partial lung shielding was done on each treatment, with supplemental electron beam treatments of the chest wall to compensate, and of the testes, a sanctuary site. This regimen was initiated to potentially reduce fatal interstitial pneumonitis as well as decrease leukemic relapse. Overall actuarial survival at 1 year for acute non-lymphocytic leukemia (ANLL) patients is 63%, while relapse-free survival at 1 year is 53%. On the other hand, for acute lymphocytic leukemia (ALL) patients, there is no significant difference between relapse or remission patients with regard to overall survival or relapse-free survival, when relapse is defined as > 5% blasts in the marrow at the time of cytoreduction. Overall actuarial survival at 1 year for ALL is 61% and relapse-free survival is 45% at 1 year. Fatal interstitial pneumonitis has dropped to 18% compared with 50% in our previous single-dose TBI regimen (1000 cGy), in which the same doses of cyclophosphamide were given prior to TBI. In conclusion, not only has fatal interstitial pneumonitis been reduced by hyperfractionation and partial lung blocking, but there may be a survival advantage in ALL patients in relapse, who have a survival equal to that of remission patients. This may indicate a greater cell kill with the higher dose (1320 cGy) attained with this regimen, in these patients with a higher leukemic cell burden

  1. Bone marrow transplantation immunology

    1977-01-01

    Tests were made to determine whether genetic resistance (GR) to bone marrow transplantation represents a natural lymphoma-leukemia defense mechanism, as follows: (C57 x AKR) F 1 hybrid mice show GR to C57 parental bone marrow cells, but not to AKR parental bone marrow cells (C3H x AKR) F 1 hybrids show no GR to bone marrow transplantation from either parental strain. However, transplantation of AKR lymphoma cells into lethally irradiated ''resistant'' (C57 x AKR) F 1 and ''nonresistant'' (C3H x AKR) F 1 hybrids produced lymphomatous spleen colonies in ''nonresistant'' hybrids but not in ''resistant'' hybrids. Thus ''resistant'' (C57 x AKR) F 1 hybrids can recognize and reject AKR lymphoma cells, but not normal AKR bone marrow cells. A normal biologic role of leukemia-lymphoma surveillance was postulated for genetic resistance to marrow transplantation, directed at antigens which, like TL, are expressed on normal hemopoietic cells of some strains, but only on leukemic cells of other strains

  2. Nonspecific suppressor T cells cause decreased mixed lymphocyte culture reactivity in bone marrow transplant patients

    Harada, M.; Ueda, M.; Nakao, S.; Kondo, K.; Odaka, K.; Shiobara, S.; Matsue, K.; Mori, T.; Matsuda, T.

    1986-01-01

    Decreased reactivity in mixed lymphocyte culture (MLC) was observed in patients within 1 yr after allogeneic and autologous bone marrow transplantation. Suppressor activity of peripheral blood mononuclear cells (PBMC) from transplant patients was studied by adding these cells as modulator cells to a bidirectional MLC with cells from normal individuals. PBMC from transplant patients markedly suppressed MLC reactivity in a dose-dependent manner. Suppressor activity was present in cells forming rosettes with sheep erythrocytes. Treatment of modulator cells with monoclonal antibodies against T cell differentiation antigens (OKT8, OKIa1) and complement completely abolished suppression of MLC. Suppressor activity was unaffected by 30 Gy irradiation. Suppressor activity declined gradually after transplantation and was inversely correlated with MLC reactivity of each patient at a significant level (p less than 0.01). These observations suggest that OKT8+ Ia+ radioresistant suppressor T cells play a role in the development of decreased MLC reactivity observed during the early post-transplant period

    2006-01-01

    Full Text Available Bone marrow transplantation (BMT is a therapeutic option for patients with genetic storage diseases. Between 1979 and 2002, eight patients, four females and four males (1 to 13 years old were submitted to this procedure in our center. Six patients had mucopolysaccharidosis (MPS I in 3; MPS III in one and MPS VI in 2, one had adrenoleukodystrophy (ALD and one had Gaucher disease. Five patients had related and three unrelated BMT donor. Three patients developed graft versus host disease (two MPS I and one MPS VI and died between 37 and 151 days after transplantation. Five patients survived 4 to 16 years after transplantation. Three patients improved (one MPS I; one MPS VI and the Gaucher disease patient, one patient had no disease progression (ALD and in one patient this procedure did not change the natural course of the disease (MPS III.

  4. Bacteriological findings in patients with bone marrow transplantation (Karl Marx University Leipzig, 1985-1987).

    Wonitzki, C; Hoffmann, F A

    1989-01-01

    The results of the bacteriological surveillance cultures for 26 patients with bone marrow transplantation (Karl Marx University Leipzig, G.D.R., 1985-1987) are presented. 5.9% of all surveillance cultures contained facultatively pathogenic germs (with Pseudomonas aeruginosa as the most frequent representative, which was the reason of a sepsis in two patients). Coagulasenegative Staphylococci and other germs with an obscure pathogenicity were isolated upon a large scale, especially from the mucous membrane regions. There are hints, that above all special strains of coagulasenegative Staphylococci "colonize" the patient's body (also for longer periods) and turn into the blood too. During the total decontamination intestinal anaerobic flora is absent. After closing of total decontamination Clostridium perfringens is the first detectable anaerobic species. During the selective decontamination systemic applications of antibiotics are able to obliterate anaerobic findings for certain periods. Recommendations for an effective arrangement of the surveillance cultures of bone marrow transplantation patients are given.

  5. Bone marrow transplantation in the patients with malignant tumor. Studies on supralethal total body irradiation

    Tatsuno, Ikuro; Saito, Yasuo

    1984-11-01

    Based on evidence gained from ten patients of allogeneic bone marrow transplantation (BMT) and eight patients of autologous BMT, recent knowledge on literatures of BMT and total body irradiation (TBI) is summarized. Interstitial pneumonia after BMT has a strong correlation with TBI. Low dose-rate and fractionation of TBI are seemed to reduce the lung injury, thereby reducing the incidence of nonleukemia deaths. BMT is applied to not only acute leukemia, malignant lymphoma and solid tumors but also to chronic leukemia. It is emphasized that several of the important prognostic factors are within the control of the transplantation team.

    2013-01-01

    Induction of therapeutic angiogenesis by autologous bone marrow mononuclear cell transplantation has been identified as a potential new option in patients with advanced lower-limb ischemia. There is little evidence of the benefit of intra-arterial cell application in upper-limb critical ischemia. We describe a patient with upper-extremity critical limb ischemia with digital gangrene resulting from hypothenar hammer syndrome successfully treated by intra-arterial autologous bone marrow mononuclear cell transplantation.

    The majority of research on understanding the illness focuses on analysing the written or verbal content. Thematic analysis of images is a novel qualitative approach that can enhance knowledge of the experience of illness. This study used thematic analysis to examine 171 tiles painted by patients through the Tiles of Hope programme in an outpatient blood and marrow transplant unit. Major themes identified in this study were Faith, Hope, Positive Attitude, Nature and Social Support. These themes provided a better understanding of patients' perceptions in relation to their experience with illness through the art-making process. © 2015 John Wiley & Sons Ltd.

  8. Radiography and bone scintigraphy in bone marrow transplant multiple myeloma patients

    Aagren, B.; Aspelin, P.

    1997-01-01

    Purpose: To compare conventional radiography and bone scintigraphy in relation to clinical outcome in bone marrow transplant multiple myeloma patients. Material and Methods: A total of 70 radiographies and 70 bone scintigraphies were compared in 35 patients. Results: The skull, the extremities, the iliac and public bones were better assessed with radiography. For new vertebral lesions and for lesions in the ribs and sternum, bone scintigraphy proved superior. For the sacrum, the methods were equal. When bone scintigraphy was used as a complement to radiography, 4% more pathological sites were found. No patient had both a normal radiography and a pathological bone scintigraphy, but 5 patients had both a normal bone scintigraphy and a pathological radiography. The results of the radiological examinations did not always correlate with the clinician's grading of the patient's disease. The radiological examinations had no prognostic value for the 7 patients examined on several occasions. Conclusion: The ability of conventional radiography and bone scintigraphy to disclose myeloma lesions varies, depending on location and size of the lesions. Radiography should remain the primary examination modality also for bone marrow transplant multiple myeloma patients. Bone scintigraphy can severe as a complement for investigating unexplained pain, e.g. caused by lesions in vertebrae or ribs. (orig.)

  9. Bone marrow transplantation after irradiation

    Koch, M.; Blaha, M.; Merka, V.

    1990-01-01

    Bone marrow transplantation after irradiation is successful in only a part of the affected patients. The Chernobyl accident added to our knowledge: BMT can save life after whole-body irradiation with a dose exceeding 7-8 Gy. A timely decision on transplantation after a nuclear accident is difficult to make (rapid determination of homogeneity and type of radiation and the total dose. HL-A typing in lymphopenia, precise identification of radiation damage to other target organs, etc.). Further attention is to be paid to the treatment. Transplantations in case of malignities (especially hematologic ones) and other diseases will add to our knowledge and will lead to more simple procedures. (author). 3 figs., 1 tab., 12 refs

  10. HLA in bone marrow transplantation

    Tsuji, Kimiyoshi

    1989-01-01

    It has been well understood that human major histocompatibility antigen system, HLA is the most important role in the allo transplantation. Therefore, the structure of HLA genes was presented by the recent information (1987). Moreover, their functions in vitro and in vivo also were described. Finally, bone marrow transplantation and HLA network system in Japan against HLA mismatched case was proposed. It is eagerly expected that functional and clinical bone marrow transplantation in Japan could be succeeded. (author)

  11. Immune reconstitution in patients with Fanconi anemia after allogeneic bone marrow transplantation.

    Perlingeiro Beltrame, Miriam; Malvezzi, Mariester; Bonfim, Carmem; Covas, Dimas Tadeu; Orfao, Alberto; Pasquini, Ricardo

    2014-07-01

    Fanconi anemia is an autosomal recessive or X-linked genetic disorder characterized by bone marrow (BM) failure/aplasia. Failure of hematopoiesis results in depletion of the BM stem cell reservoir, which leads to severe anemia, neutropenia and thrombocytopenia, frequently requiring therapeutic interventions, including hematopoietic stem cell transplantation (HSCT). Successful BM transplantation (BMT) requires reconstitution of normal immunity. In the present study, we performed a detailed analysis of the distribution of peripheral blood subsets of T, B and natural killer (NK) lymphocytes in 23 patients with Fanconi anemia before and after BMT on days +30, +60, +100, +180, +270 and +360. In parallel, we evaluated the effect of related versus unrelated donor marrow as well as the presence of graft-versus-host disease (GVHD). After transplantation, we found different kinetics of recovery for the distinct major subsets of lymphocytes. NK cells were the first to recover, followed by cytotoxic CD8(+) T cells and B cells, and finally CD4(+) helper T cells. Early lymphocyte recovery was at the expense of memory cells, potentially derived from the graft, whereas recent thymic emigrant (CD31(+) CD45RA(+)) and naive CD4(+) or CD8(+) T cells rose only at 6 months after HSCT, in the presence of immunosuppressive GVHD prophylactic agents. Only slight differences were observed in the early recovery of cytotoxic CD8(+) T cells among those cases receiving a graft from a related donor versus an unrelated donor. Patients with GVHD displayed a markedly delayed recovery of NK cells and B cells as well as of regulatory T cells and both early thymic emigrant and total CD4(+) T cells. Our results support the utility of post-transplant monitoring of a peripheral blood lymphocyte subset for improved follow-up of patients with Fanconi anemia undergoing BMT.

    Full Text Available Introduction. A total of 18 patients, with complete motor deficits and paraplegia caused by thoracic and lumbar spine trauma without muscle atrophy or psychiatric problems, were included into this study. Materials and Methods. The bone marrow was aspirated from the anterior iliac crest under local anesthesia and the mononuclear fraction was isolated by density gradient method. At least 750 million mononuclear-enriched cells, suspended in 2 mL of saline, were infused intrathecally. Results and Discussion. The study reports demonstrated improvement of motor and sensory functions of various degrees observed in 9 of the 18 (50% cases after bone marrow stem cell transplantation. Measured by the American Spinal Injury Association (ASIA scale, 7 (78% out of the 9 patients observed an improvement by one grade, while two cases (22% saw an improvement by two grades. However, there were no cases in which the condition was improved by three grades. Conclusions. Analysis of subsequent treatment results indicated that the transplantation of mononuclear-enriched autologous BMSCs is a feasible and safe technique. However, successful application of the BMSCs in the clinical practice is associated with the necessity of executing more detailed examinations to evaluate the effect of BMSCs on the patients with spinal cord injury.

  13. Immunosuppression prior to marrow transplantation for sensitized aplastic anemia patients: comparison of TLI with TBI

    Shank, B.; Brochstein, J.A.; Castro-Malaspina, H.; Yahalom, J.; Bonfiglio, P.; O'Reilly, R.J.

    1988-01-01

    From May 1980 through July 1986, 26 patients with severe aplastic anemia, sensitized with multiple transfusions of blood products, were treated on either of two immunosuppressive regimens in preparation for bone marrow transplantation from a matched donor. There were 10 patients treated with total body irradiation (TBI), 200 cGy/fraction X 4 daily fractions (800 cGy total dose), followed by cyclophosphamide, 60 mg/kg/d X 2 d. An additional 16 patients were treated with total lymphoid irradiation (TLI) [or, if they were infants, a modified TLI or thoracoabdominal irradiation (TAI)], 100 cGy/fraction, 3 fractions/d X 2 d (600 cGy total dose), followed by cyclophosphamide, 40 mg/kg/d X 4 d. The extent of immunosuppression was similar in both groups as measured by peripheral blood lymphocyte depression at the completion of the course of irradiation (5% of initial concentration for TBI and 24% for TLI), neutrophil engraftment (10/10 for TBI and 15/16 for TLI), and time to neutrophil engraftment (median of 22 d for TBI and 17 d for TLI). Marrow and peripheral blood cytogenetic analysis for assessment of percent donor cells was also compared in those patients in whom it was available. 2/2 patients studied with TBI had 100% donor cells, whereas 6/11 with TLI had 100% donor cells. Of the five who did not, three were stable mixed chimeras with greater than or equal to 70% donor cells, one became a mixed chimera with about 50% donor cells, but became aplastic again after Cyclosporine A cessation 5 mo post-transplant, and the fifth reverted to all host cells by d. 18 post-transplant. Overall actuarial survival at 2 years was 56% in the TLI group compared with 30% in the TBI group although this was not statistically significant. No survival decrement has been seen after 2 years in either group

    Patients undergoing a bone marrow stem cell transplant (BMT) face various risk factors. Analyzing data from past transplants could enhance the understanding of the factors influencing success. Records up to 120 measurements per transplant procedure from 1751 patients undergoing BMT were collected (Shariati Hospital). Collaborative filtering techniques allowed the processing of highly sparse records with 22.3% missing values. Ten-fold cross-validation was used to evaluate the performance of various classification algorithms trained on predicting the survival status. Modest accuracy levels were obtained in predicting the survival status (AUC = 0.69). More importantly, however, operations that had the highest chances of success were shown to be identifiable with high accuracy, e.g., 92% or 97% when identifying 74 or 31 recipients, respectively. Identifying the patients with the highest chances of survival has direct application in the prioritization of resources and in donor matching. For patients where high-confidence prediction is not achieved, assigning a probability to their survival odds has potential applications in probabilistic decision support systems and in combination with other sources of information.

    A preparative regimen, consisting of total lymphoid irradiation and cyclophosphamide, was utilized in 40 patients with severe aplastic anemia undergoing allogeneic marrow transplantation. This regimen was successful in decreasing rejection in these previously transfused patients, as only one patient rejected the marrow graft. Twenty-nine of the 40 transplanted patients are surviving from 1.5 to 59 mo, with a median follow-up of 24 mo. The actuarial survival rate for these heavily transfused patients with aplastic anemia is 72% at 2 yr. This preparative regimen is extremely effective in decreasing rejection following transplantation for severe aplastic anemia. Future efforts in this area must be aimed at the elimination of graft-versus-host disease and control of fatal infections

    1976-09-25

    Of 75 patients with asplastic anaemia treated between 1968 and 1975, 33 were retrospectively considered as potential candidates for allogenegic bone-marrow transplantation on the basis of their age and severity of marrow failure. The prognosis of these patients with conservative treatment was assessed from parameters obtained at the time of the initial diagnosis. Initial peripheral-blood granulocyte or platelet concentrations were not of porgnostic value. In contrast, initial reticulocyte concentrations, allowed separation of the patients into two groups with poor and good prognosis. Low initial reticulocyte concentrations (less than 10 000/mu1) indicated those patients at extremely high risk of succumbing to their marrow aplasia (there were no survivors 36 months after disgnosis). In contrast, 75% of those patients with more than 10 000 reticulocytes per mu1 at diagnosis survived for 3 years. Initial peripheral-blood reticulocyte concentrations thus appear to indicate the extent of the marrow failure in aplastic anaemia more accurately than granulocytes or platelets. Low initial reticulocyte concentrations may indicate, among patients with severe aplastic anaemia, those for whom allogeneic bone-marrow transplantation should be seriously considered; patients with higher initial reticulocyte concentrations may benefit from conservation treatment.

    Purpose: Approximately 5% to 20% of patients who undergo total body irradiation (TBI) in preparation for hematopoietic cell transplantation (HCT) can develop extramedullary (EM) relapse. Whereas total marrow and lymphoid irradiation (TMLI) provides a more conformally targeted radiation therapy for patients, organ sparing has the potential to place the patient at a higher risk for EM relapse than TBI. This study evaluated EM relapse in patients treated with TMLI at our institution. Methods and Materials: Patients eligible for analysis had been enrolled in 1 of 3 prospective TMLI trials between 2006 and 2012. The TMLI targeted bones, major lymph node chains, liver, spleen, testes, and brain, using image-guided tomotherapy with total dose ranging from 12 to 15 Gy. Results: A total of 101 patients with a median age of 47 years were studied. The median follow-up was 12.8 months. Incidence of EM relapse and bone marrow (BM) relapse were 12.9% and 25.7%, respectively. Of the 13 patients who had EM relapse, 4 also had BM relapse, and 7 had EM disease prior to HCT. There were a total of 19 EM relapse sites as the site of initial recurrence: 11 soft tissue, 6 lymph node, 2 skin. Nine of these sites were within the target region and received ≥12 Gy. Ten initial EM relapse sites were outside of the target region: 5 sites received 10.1 to 11.4 Gy while 5 sites received <10 Gy. Pretransplantation EM was the only significant predictor of subsequent EM relapse. The cumulative incidence of EM relapse was 4% at 1 year and 11.4% at 2 years. Conclusions: EM relapse incidence was as frequent in regions receiving ≥10 Gy as those receiving <10 Gy. EM relapse rates following TMLI that included HCT regimens were comparable to published results with regimens including TBI and suggest that TMLI is not associated with an increased EM relapse risk.

  1. Nursing challenges caring for bone marrow transplantation patients with graft versus host disease.

    Neumann, Joyce

    2017-12-01

    Nursing care of blood and marrow transplantation (BMT) patients is complicated. Nursing considerations of BMT patients with GVHD require an additional set of skills and knowledge that include side effects, both expected and less common, assessment skills, treatment administration, both standard and novel, and acute or intensive care. Nursing care of BMT patients with skin GVHD will be determined by the degree of skin alteration with distinct decisions made about hygiene, both topical and systemic treatment, infection prevention, relief of discomfort, functional ability (ADL) and body image alteration. The nurse needs to have knowledge about assessment criteria for acute and chronic (NIH) assessment with special attention to skin (presence of rash, texture, mobility), joint mobility, mouth care, dressings, and skin care products. Nursing consideration of gastrointestinal GVHD includes importance of accurate intake and output, obtaining culture, fluid and electrolyte imbalance, nutrition, treatment, and skin care. Complication of GVHD treatment, namely effects of steroids require experts from many disciplines to provide comprehensive care. Caring and advocating for GVHD patients may include preparing for outcomes that are undesirable and impact the patient's quality of life and mortality. BMT survivorship programs are a major source of patient education about chronic GVHD for patients after treatment. Caring for BMT patients, especially those experiencing GVHD, takes a knowledgeable, committed, and caring team of healthcare providers. Workshops like this are vital in providing information and networking to keep providers around the region and globe engaged in this critical work. Copyright © 2017. Published by Elsevier B.V.

    1999-01-01

    This study examines the problems of bone marrow transplantation (BMT) survivors in returning to "normal" life in the community after BMT. Before being released from The Johns Hopkins Oncology Center, 84 recipients of BMT were interviewed regarding their quality of life and psychosocial adaptation. Survivors were reinterviewed at 6 months, and at 1 year post-BMT, producing considerable qualitative data regarding their problems in living. Eighty-four patients who had received BMT completed qualitative interviews and standardized measures before treatment, before the return home, and at 6 and 12 months post-BMT. The interviews were subjected to a content analysis methodology to establish units and categories to examine the body of material. Content analysis of these interviews from the first year after BMT identified three areas of psychosocial morbidity; 1) physical problems, which included fatigue, appearance, troubles in eating, and physical restrictions; 2) psychological problems, which included fears about the future, sense of loss of control, anxiety, and depression; and 3) community reintegration problems, which included difficulty in returning to former social roles, separation from home, family, and friends, difficulty in resuming social relations, dealing with stigmatization, problems with family and children, and financial and employment difficulties. Identification of these problems for BMT survivors can be used to guide the development of specific materials and services to prepare recipients of BMTs and their families for life after the transplant. These qualitative results can also be used to direct the development of assessment tools to identify potential patient and family problems.

    Since 1976, 16 adult patients with acute leukemia have been treated by chemotherapy, total body irradiation (TBI) and allogeneic bone marrow transplantation (BMT) in the medical school hospital and the satellite hospitals of Nagoya University. The first group of 10 patients were given marrow grafts at the time of leukemic relapse and the second group of six patients were given the grafts in the period of remission of their disease. For the first group (ALL/ANLL 2:8, age (median) 33, M/F 8:2), HLA-identical donor cells (25 x 10/sup 7//kg(median)) were infused after the patients were conditioned with NSC D 245382 (ACNU) or daunorubicin, cyclophosphamide (CY) and a single shot of 1000 rad of TBI. For the second group (ALL/ANLL 4:2, age (median) 20, M/F 5:1), HLA-identical donor cells (22 x 10/sup 7//kg(median)) were infused after the patients were conditioned with CY and fractionated (250 rad x 4) TBI. All the patients were isolated in a laminar air flow room (LAF) after gut and skin decontamination. Engraftment of donor cells was confirmed in 15 out of the 16 patients. Febrile periods in LAF and the days required for platelet transfusion were prolonged in the first group. All the patients in the first group died within 12-214 days after BMT because of interstitial pneumonitis (7 patients) or bacterial infection (3 patients). On the other hand, five out of six patients in the second group are alive 84-540 days after BMT. For the surviving patients, the complications of chronic graft versus host disease, viral infections, tuberculosis, hepatitis, hemorrhagic cystitis and recurrence of leukemia are now the problems. It can be stated that the patient's clinical condition at the time of BMT is one of the most essential factors for the success of BMT although the effects of other variables, such as a change in the conditioning regimens or the supportive care, must also be carefully analyzed.

  8. "A day in my life" photography project: the silent voice of pediatric bone marrow transplant patients.

    2014-01-01

    A photovoice project was conducted with pediatric bone marrow transplant (BMT) patients to examine their coping skills and interpretation of their experience during a BMT, especially when hospitalized. We also wanted to determine how photovoice could be used within a pediatric BMT unit. Sixteen children (ages 4-14) and 2 young adults (ages 22 and 25) from a pediatric BMT unit participated in the project. Six BMT outpatients participated in the data analysis and evaluation phase. Fourteen clinical staff evaluated the impact of the project on their practice. Three primary themes emerged from the pre- and post-BMT photos, accompanying detailed notes, and BMT outpatient analysis of the photos: (a) BMT is "torture," (b) BMT is "time slipping away," and (c) BMT requires normalization, comfort, distraction, and support. BMT patients and staff concluded that photovoice helped express and release emotions regarding the challenges of BMT. BMT staff noted that the results of this project reminded them of the importance of being patient-centered and mindful of patient experience and the therapeutic relationship. © 2014 by Association of Pediatric Hematology/Oncology Nurses.

    1977-01-01

    A child with severe neutrophil dysfunction and intractable infections received bone marrow transplants from histocompatible siblings. After a first transplant preceded by cyclophosphamide (CY), antithymocyte serum (ATS) and procarbazine (PCB) preconditioning, there was no evidence for engraftment and autologous marrow function rapidly returned. Cell mediated lysis showed no evidence of patient sensitization against the marrow donor suggesting that graft rejection did not cause the transplant failure. A second transplant was performed utilizing another matched sibling donor. Total body irradiation was added to CY, ATS, and PCB for preconditioning after in vitro studies of the colony forming capacity (CFUsub(c)) of the patient's marrow cells showed normal sensitivity to radiation. Full engraftment ensued with correction of granulocyte function abnormalities. The patient eventually died of intractable pulmonary disease. Experience with this child suggests that cyclophosphamide alone may be insufficient preparation for marrow transplantation in some patients with non-neoplastic hematologic disorders. Experimental and clinical data supporting this contention are reviewed.

    A 28-yr-old woman with acute malignant myelosclerosis received, as primary treatment, ablative chemotherapy and total body radiation therapy followed by bone marrow transplantation from her histocompatible brother. The patient is now well more than 15 mo after bone marrow transplantation, with normal peripheral blood counts, a normal bone marrow, no evidence of graft-versus-host disease, and is on no therapy. In light of the poor results obtained with conventional chemotherapy in this disease, bone marrow transplantation may represent the treatment of choice for patients who have an appropriate donor

    Thirty-six lesions in six patients who died from cerebral Aspergillus infection after bone marrow transplantation (BMT) were studied with regard to signal intensity, contrast enhancement, size, and location. The diagnosis was confirmed in all cases by autopsy. Retrospective correlation of histopathological and radiological findings was possible for 14 lesions. Most of the lesions (22/36) had isointense to low signal intensity on T2-weighted images (T2WI). Histopathologically, hemorrhagic necrosis was determined in three of them. Areas of high signal intensity on T1-weighted images (T1WI) were related to gross hemorrhage. Two infarctions showed intravascular accumulation of fungal hyphae with secondary thrombosis of the vessel. The remaining 12 lesions had high signal intensity on T2WI and low on T1WI. Histopathologically, four were infectious and four were unspecific demyelinated lesions. In conclusion, cerebral aspergillosis typically presented with large lesions showing isointense to low signal intensity on T2WI that could have areas of high signal on T1WI. Contrast enhancement was only visible in 15 lesions, and the predominant locations were the subcortical white matter, the cerebellum, and the basal ganglia. Small lesions with high signal on T2WI and low signal on T1WI could not necessarily be related to Aspergillus infection. (orig.)

  13. An informative constitutional cytogenetic marker found in a patient post bone marrow transplantation

    1994-09-01

    It is cytogenetically difficult to distinguish between host and donor cells in allogeneic bone marrow transplantation (BMT) individuals of the same sex. Here we describe a patient with a cytogenetic marker found after BMT. A 7-month-old male presented with leukemia which was CD7+, CD33+, HLADR+, and CD4-, CD8-, indicating a diagnosis of acute stem cell leukemia (ASCL). Cytogenetic analysis revealed an abnormal clone in all of the cells analyzed: 46,XY,t(2;8)(p11.2;q24),inv(9)(p13p24). This translocation is associated with B-cell acute lymphoblastic leukemia (ALL); thus, it was possible for this patient to develop B-cell ALL. The abnormal clone persisted along with normal 46,XY cells, and evolved in several of seven additional analyses. The patient was treated with two courses of chemotherapy and failed to attain cytogenetic remission. While in relapse, the patient received a BMT from his 3-year-old brother. Two weeks later, a different translocation was seen in all cells: 46,XY,t(3;12)(p21;q21). This result could be interpreted in two ways: (1) the structural abnormality was indicative of a newly evolved clone related to the patient`s disease; or (2) the donor was a balanced translocation carrier. Cytogenetic analysis of peripheral blood from the donor revealed the same translocation seen in the patient. Parental blood chromosomes were normal indicating that the donor carried a de novo balanced translocation. Subsequent chromosome analysis of both peripheral blood and BM from the patient revealed the presence of the translocation in all cells. De novo balanced translocations are rare and occur with a frequency of 1/2,000 live borns. The family received genetic counseling and was informed of the possible reproductive risks to translocation carriers. This unusual finding will serve as a useful cytogenetic marker to assist in monitoring the patient`s clinical course, i.e., chimerism and remission status.

  14. Assessment of renal function in patients with hematologic malignancies undergoing bone marrow transplantation

    Patients with hematologic malignancies undergoing bone marrow transplantation (BMT) may develop renal insufficiency. Isotopic determinations of glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) are established methods to evaluate renal function. Aim: To asses renal function changes of patients with hematologic malignancies undergoing BMT by measurements of GFR and ERPF using 51Cr-EDTA and 131I-OIH respectively. Methods: Seventy-one patients (mean age 41 years) were studied prospectively. All patients underwent BMT for hematologic malignancies and had previous normal renal function. Their conditioning included chemotherapy and 12 Gy or 13.5 Gy fractionated total body irradiation (TBI). Kidney shielding blocks fabricated after renal opacification with non-ionic, hypo-osmolar contrast medium were used in 21 patients to limit kidney dose to 10 Gy. GFR and ERPF were measured before conditioning and at 4, 12, and 18 months, using 51Cr-EDTA and 131I-OIH respectively. A decrease of 30% in GFR or ERPF, compared with baseline values, was used to define renal insufficiency. The potential influence of patient- and treatment-related variables on renal dysfunction was assessed. Results: At 4 (early) and 12-18 (late) months, a 30% GFR decrease was observed in 54% and 49% of patients, and a 30% ERPF decrease in 44% and 34% of patients, respectively. GFR decrease at 4 months significantly correlated with age (greatest decrease if <40 years), TBI using kidney blocks (kidney shielding to 10 Gy was associated with a higher rate of renal dysfunction at 4 months compared with full TBI dose), and days of treatment with aminoglycosides/vancomycin. ERPF decrease at 4 months was independently related with amphotericin and prostaglandin E1 (PGE1) treatments. GFR and ERPF decrease at 12-18 months correlated with amphotericin and PGE1 treatments. Conclusion: Early post-BMT renal dysfunction is associated with the administration of potentially nephrotoxic drugs. Younger

  15. Selective engraftment of the granulocyte compartment after allogeneic bone marrow transplantation in a patient with severe aplastic anemia.

    Barriga, F J; Legues, M E; Bertin, P

    1996-05-01

    We present a patient with severe aplastic anemia who had partial engraftment with full chimerism after allogeneic bone marrow transplantation from an HLA identical sibling. A 3-year-old girl with severe aplastic anemia (SAA) received a bone marrow transplantation (BMT) from an HLA identical brother 9 months after her diagnosis. Before BMT she was red blood cell tranfusion dependent, had an absolute neutrophil count (ANC) of 1,000-1,500 x 10(9)/1 and a platelet count of 15-19,000 x 10(9)/1. She was conditioned with 800 cGy total body irradiation (TBI) and cyclophosphamide and received 3X10(8) nucleated cells/kg. She reached an ANC of 1500 x 10(9)/1 on day +35 but her reticulocyte and platelet counts did not recover. A bone marrow aspirate and biopsy post BMT showed hypoplasia with marked decrease in megakaryocyte and red blood cell precursors. The granulocyte compartment showed a left shift with predominance of promyelocytes and myelocytes. The karyotype showed full chimerism (46,XY) with no 46,XX metaphases. This case illustrates the possibility of a bone marrow microenvironment defect as the cause of SAA.

American Society of Blood and Marrow Transplantation, European Society of Blood and Marrow Transplantation, Blood and Marrow Transplant Clinical Trials Network, and International Myeloma Working Group Consensus Conference on Salvage Hematopoietic Cell Transplantation in Patients with Relapsed Multiple Myeloma

    Giralt, Sergio; Garderet, Laurent; Durie, Brian

    2015-01-01

    convened a meeting of MM experts to: (1) summarize current knowledge regarding the role of autologous or allogeneic HCT in MM patients progressing after primary therapy, (2) propose guidelines for the use of salvage HCT in MM, (3) identify knowledge gaps, (4) propose a research agenda, and (5) develop...... a collaborative initiative to move the research agenda forward. After reviewing the available data, the expert committee came to the following consensus statement for salvage autologous HCT: (1) In transplantation-eligible patients relapsing after primary therapy that did NOT include an autologous HCT, high...... inhibitors; (5) Autologous HCT consolidation should be explored as a strategy to develop novel conditioning regimens or post-HCT strategies in patients with short (less than 18 months remissions) after primary therapy; and (6) Prospective randomized trials need to be performed to define the role of salvage...

  17. The Basel experience with total body irradiation for conditioning patients with acute leukemia for allogenic bone marrow transplantation

    Speck, B.; Cornu, P.; Nissen, C.; Gratwohl, A.; Sartorius, J.

    1979-01-01

    We are reporting our experience with 13 patients suffering from end stage acute leukemia that were prepared for allogeneic bone marrow transplantation by combined chemotherapy followed by high dose cyclophosphamide (Cy) and total body irradiation (TBI). Only one patient became a long term survivor. Of the evaluable 12 patients, 6 died of interstitial pneumonia, 4 of GvH and 1 of recurrent leukemia. We conclude that adding combined chemotherapy to the standard conditioning program with Cy and TBI probably increases the risk of developing fatal interstitial pneumonia without eliminating the risk of recurrent leukemia. We suggest that allogenic marrow grafts should be performed earlier in the course of refractory acute leukemias, because in patients with end stage disease its chances of being curative are small

  18. Successful bone marrow transplantation in sensitized recipients

    Levey, R.H.; Parkman, J.; Rappeport, J.; Nathan, D.G.; Rosen, F.

    1979-01-01

    Fourteen patients with aplastic anemia and one with the Wiskott-Aldrich syndrome who were specifically sensitized against their donors were successfully engrafted with bone marrow from those donors. Sensitivity was detected in antibody-independent and antibody-dependent cell-mediated lysis assays. In order to erase this immunity to non-MHR familial transplantation antigens, multiagent immunosuppression with cyclophosphamide, procarbazine, and whole rabbit antithymocyte serum (ATS) was used. The data suggest that ATS was largely responsible for abrogation of this sensitivity and indicate that immunity does not represent a barrier to successful transplantation

  20. The nucleic acids as early indicators of the recovery of patients subjected to total body irradiation for bone marrow transplant

    Morera Carrillo, L.M.; Garcia Lima, O.; Carnot, J.; Cardenas, J.

    2000-01-01

    The possibility to use the concentration of nucleic acids as an early indicator for the recovery of individuals exposed to high radiation was valued in 30 patients subjected to a dose of 10 Gy (cobalt 60) in two or three sessions of total body irradiation for bone marrow transplants. The determination of the concentration of the nucleic acids was carried out prior to the irradiation, and later in different periods until the patients discharge. The behaviour of indicate such as alpha amylase serics transaminases, glicemics, alkaline phosphatase and others was also studied

    Lymphocytes from patients after bone marrow transplantation (BMT) are in most cases predominantly of the Leu-2+ (cytotoxic/suppressor) phenotypes and are almost unresponsive to mitogens. In contrast, normal Leu-3+-depleted, Leu-2+-enriched lymphocyte suspensions retain approximately 50...

  3. Bone marrow transplantation for childhood malignancies

    Toyoda, Yasunori

    1992-01-01

    As of June 30, 1991, 1013 pediatric patients had registrated to The Bone Marrow Transplantation Committee of the Japanese Society of Pediatric Hematology. Bone marrow transplantation (BMT) from HLA-matched siblings is now reasonably safe and an established method of treatment in acute leukemia. Total body irradiation, which is major part of preparative regimen for BMT, affect endocrine function, subsequent growth, gonadal function, development of secondary malignancies. We propose the indication of TBI for children and young adults as follows; those who are at high risk for leukemic relapse after BMT such as Phl-positive-All, leukemia-lymphoma syndrome, AML with monocytic component, BMT in elapse, BMT from other than HLA-matched siblings.

  4. Bone marrow ablation with Ho-166 pharmaceuticals as preparation for bone marrow transplants

    Parks, N.J.; Kawakami, T.; Avila, M.; White, R.; Cain, G.; Moore, P.F.

    1991-01-01

    Bone marrow ablation is required preparation for leukemia patients where bone marrow transplantation is to be the therapeutic modality. Presently, the total body irradiation that is used produces appreciable morbidity in terms of radiation sickness, but an evenly distributed dose to marrow. The authors have shown in Beagles that bone-seeking radiolanthanide (Ho-166, t 1/2 = 25 h, 1.8 MeB beta, carrier added) phosphonic acid chelates can be used to completely ablate bone marrow with little morbidity. The research plan, incorporating bone marrow ablation with bone-seeking radionuclides and in vitro purging of aspirated leukemic marrow for use in autologous marrow transplants, is presented. Phosphonic acid complexes of Sm-153 also localize in the skeleton and have found use in the palliation of bone pain. However, the dose distribution is uneven because these radiopharmaceuticals distribute according to available surface; 2-4 times the skeletal average in trabecular vs cortical bone. Thus, the marrow dose can vary. The authors' research group and the Radiation Interactions Division of NIST have announced the discovery that beta radiation-induced excited electrons are trapped in the hydroxyapatite mineral of bone and provide a potential direct dosimetric method for marrow dose when combined with routine bone marrow (and included bone) biopsies. The overall research plan sets the hypothesis that reduced morbidity marrow ablation can be successfully followed by bone marrow transplantation (BMT) with autologous marrow purged in vitro by antibody-targeted alpha emitters

  5. Iron overload following bone marrow transplantation in children: MR findings

    Kornreich, L.; Horev, G.; Grunebaum, M.; Yaniv, I.; Stein, J.; Zaizov, R.

    1997-01-01

    Objective. The purpose of this study was to determine the incidence of post-transfusional iron overload in children after bone marrow transplantation by reviewing their magnetic resonance imaging (MR) findings. Materials and methods. We reviewed the abdominal MR studies of 13 children after autologous bone marrow transplantation. Nine of the children had also undergone MR prior to transplantation. Iron deposition in the liver, spleen and bone marrow was graded semi-quantitatively on both T1- and T2-weighted images. Serum ferritin levels and number of blood units given after bone marrow transplantation were recorded. Results. None of the pre-transplantation MR studies revealed iron overload. After bone marrow transplantation, three children showed normal liver and spleen. Iron overload in the liver was noted in ten patients (77 %), six of whom also showed iron overload in the spleen (46 %) and five in the bone marrow (38.5 %). The degree of hepatic iron overload was correlated significantly and splenic iron overload was correlated weakly with the number of blood transfusions (P 0.01 and P > 0.01, respectively), but neither was correlated with the serum ferritin level. Conclusion. Iron overload commonly accompanies bone marrow transplantation. The observed pattern of iron deposition, in which the spleen was uninvolved in 40 % of patients demonstrating iron overload, is not typical of post-transfusional hemochromatosis. (orig.)

    2015-01-01

    Full Text Available Background: Human bone marrow transplantation (BMT becomes an accepted treatment of leukemia, aplastic anemia, immunodeficiency syndromes, and hematologic malignancies. Colorectal surgeons must know how to determine and manage the main colonic complications. Objective: To review the clinical features, clinical and pathological staging of graft vs host disease (GVHD, and treatment of patients suffering with colonic complications of human bone marrow transplantation. Patients and methods: We have reviewed the records of all patients that received an allogeneic bone marrow transplant and were evaluated at our Colon and Rectal Surgery department due to gastrointestinal symptoms, between January 2007 and January 2012. The study was carried out in patients who developed colonic complications, all of them with clinical, histopathological or laboratory diagnosis. Results: The study group was constituted by 77 patients, 43 male and 34 female patients. We identified colonic complications in 30 patients (38.9%; five patients developed intestinal toxicity due to pretransplant chemotherapy (6.4%; graft vs. host disease was present in 16 patients (20%; 13 patients (16.8% developed acute colonic GVHD, and 3 (3.8% chronic GVHD. Infection was identified in 9 patients (11.6%. Conclusions: The three principal colonic complications are the chemotherapy toxicity, GVHD, and superinfection; the onset of symptoms could help to suspect the type of complication (0–20 day chemotherapy toxicity, 20 and more GVHD, and infection could appear in any time of transplantation.

  7. The kinetics of early T and B cell immune recovery after bone marrow transplantation in RAG-2-deficient SCID patients.

    Atar Lev

    Full Text Available The kinetics of T and B cell immune recovery after bone marrow transplantation (BMT is affected by many pre- and post-transplant factors. Because of the profoundly depleted baseline T and B cell immunity in recombination activating gene 2 (RAG-2-deficient severe combined immunodeficiency (SCID patients, some of these factors are eliminated, and the immune recovery after BMT can then be clearly assessed. This process was followed in ten SCID patients in parallel to their associated transplant-related complications. Early peripheral presence of T and B cells was observed in 8 and 4 patients, respectively. The latter correlated with pre-transplant conditioning therapy. Cells from these patients carried mainly signal joint DNA episomes, indicative of newly derived B and T cells. They were present before the normalization of the T cell receptor (TCR and the B cell receptor (BCR repertoire. Early presentation of the ordered TCR gene rearrangements after BMT occurred simultaneously, but this pattern was heterogeneous over time, suggesting different and individual thymic recovery processes. Our findings early after transplant could suggest the long-term patients' clinical outcome. Early peripheral presence of newly produced B and T lymphocytes from their production and maturation sites after BMT suggests donor stem cell origin rather than peripheral expansion, and is indicative of successful outcome. Peripheral detection of TCR excision circles and kappa-deleting recombination excision circles in RAG-2-deficient SCID post-BMT are early markers of T and B cell reconstitution, and can be used to monitor outcome and tailor specific therapy for patients undergoing BMT.

  8. Screening for Y Chromosome Microdeletion in a Nonobstructive Azoospermic Male Patient with Allogeneic Bone Marrow Transplantation from His Sister

    Hakan Gurkan

    2010-01-01

    Full Text Available Genomic DNA of a patient diagnosed with nonobstructive azoospermia and with the history of allogenic bone marrow transplantation from his sister due to chronic myeloid leukemia was isolated from peripheral blood in order to screen Y chromosome microdeletions. 13 short tagged sites belonging to AZF a, b, and c loci were detected with multiplex polymerase chain reaction technique. Bands were determined in ZFX/ZFY wells, whereas no bands were determined in wells of other STS regions. DNA isolation was done from buccal mucosa smear to obtain genomic DNA from patient's own cells and multiplex polymerase chain reaction technique was performed again. Bands were seen in all wells of 13 STS regions. Y chromosome microdeletion was not detected in the patient. In conclusion, genomic DNA isolation in patients undergoing BMT should be done from patients' own cells.

  10. Bone marrow transplantation - a field in continuous development

    Pfeffer, P.F.

    1975-01-01

    The symptoms of the radiation syndrome are described briefly and the Vinca accident in 1958 is used as an illustration of the application of bone marrow transplantation as a treatment in radiation accidents. Thereafter the immunological problems arising when a permanent substitution of donor marrow is required are discussed. Greatest experience in bone marrow transplantation has been had in the treatment of aplastic anemia and acute leukemia. In these cases the recipient's bone marrow cells must be killed by whole body irradiation or by cyclophosphamide to preclude graft-host reaction. The removal of marrow from the donor and transplanting in the recipient are described, as is the progress of the patient in a typical case. The graft-host reaction is then discussed, as is the danger of secondary infections. In conclusion the long term results are evaluated and the future developments of the treatment discussed. (JIW)

  11. A qualitative study of blood and marrow transplant patient experiences participating in art making and music listening.

    Mische Lawson, Lisa; Wedan, Lindsay; Stock, Morgan; Glennon, Cathy

    2016-06-01

    To explore patient experiences of engaging in art making or music listening while receiving treatment in a blood and marrow transplant clinic. Researchers recruited 25 individuals receiving blood and marrow transplant (BMT) treatment, 12 men and 13 women aged 22 to 74, from a Midwestern outpatient BMT clinic. Participants engaged in a painting activity or listened to music on an iPad using an internet music application for one hour. Researchers interviewed participants after the one-hour activity to gain insight into participants' perceptions of the art making or music listening experience. Interviews were recorded, transcribed verbatim, and independently coded by members of the research team. Researchers met on several occasions to analyse codes and agree on emerging themes. Nine themes emerged from the data including, Engaging in Activity, Art and Music in Daily Life, Expression, Engaging with Equipment, Novelty, BMT Process, Activity Process, Social Support, and Living Situation. Participants enjoyed art making and music listening and found the activities beneficial during treatment. Participants benefited from art making and music listening because these activities increased the variety of options available during treatment, allowed for self-expression, and could be done alone or with caregivers.

  12. Hemolytic uremic syndrome after bone marrow transplantation

    Arai, Ayako; Sakamaki, Hisashi; Tanikawa, Shu [Tokyo Metropolitan Komagome Hospital (Japan)] [and others

    1998-06-01

    One hundred and thirteen patients who underwent autologous or allogeneic bone marrow transplantation (BMT) were investigated for the subsequent development of hemolytic uremic syndrome (HUS). HUS developed in seven patients (four males and three females, five acute lymphocytic leukemia (ALL), one acute myelogenous leukemia, one non-Hodgkin`s lymphoma) between 36-196 days after BMT. Four patients were recipients of autologous BMT and three were those of allogeneic BMT. Six patients were preconditioned with the regimens including fractionated total body irradiation (TBI). ALL and preconditioning regimen with TBI were suspected to be the risk factors for the development of HUS. Cyclosporin A (CSP) administration was discontinued in three patients who had been given CSP for graft-versus-host disease prophylaxis. Predonisolone was given to the three patients and plasma exchange was performed in one patient. Both hemolytic anemia and thrombocytopenia were resolved in virtually all patients, while creatinine elevation has persisted along with hypertension in one patient. (author)

  13. IgE antipolymyxin B antibody formation in a T cell-depleted bone marrow transplant patient

    Lakin, J.D.; Grace, W.R.; Sell, K.W.

    1975-01-01

    The production of IgE-class antibody specific for polymyxin B is documented in an 18-year-old white female acute myelocytic leukemic patient in relapse. The patient was rendered T cell--deficient by total-body x irradiation and antihuman thymocyte globulin for the purpose of bone marrow transplantation. Thereafter, symptoms of nasal congestion, rhinorrhea, and perinasal urtication produced by topical application of a polymyxin solution were noted. Reaginic activity mediated by an IgE antibody against polymyxin is documented by Prausnitz-Kuestner--type passive transfer reactions and by an indirect hemagglutination technique developed for these studies. The occurrence of type I hypersensitivity to this topical antibiotic is rare. It is speculated that pharmaceuticals normally having a low sensitizing potential might demonstrate increased reaginic immunogenicity in a spontaneously or iatrogenically T cell-depleted patient

    2009-12-01

    Full Text Available The clinical application of cellular based therapies with ex vivo cultivation for the treatment of diseases of the musculoskeletal system has until now been limited. In particular, the advanced laboratory and technical effort necessary, regulatory issues as well as high costs are major obstacles. On the other hand, newly developed cell therapy systems permit intra-operative enrichment and application of mesenchymal and progenitor stem cells from bone marrow aspirate concentrate (BMAC in one single operative session. The objective of the present clinical surveillance study was to evaluate new bone formation after the application of BMAC as well as to record any possible therapy-specific complications For this purpose, the clinical-radiological progress of a total of 101 patients with various bone healing disturbances was documented (surveillance study. The study included 37 necrosis of the head of the femur, 32 avascular necroses/bone marrow edema of other localization, 12 non-unions, 20 other defects. The application of BMAC was performed in the presence of osteonecrosis via a local injection as part of a core decompression (n=72 or by the local adsorption of intra-operative cellular bone substitution material (scaffold incubated with BMAC during osteosynthesis (n=17 or in further surgery (n=12. After an average of 14 months (2-24 months, the patients were re-examined clinically and radiologically and interviewed. Further surgery was necessary in 2 patients within the follow-up period. These were due to a progression of a collapsed head of the femur with initial necrosis in ARCO Stage III, as well as inadequate new bone formation with secondary loss of correction after periprosthetic femoral fracture. The latter healed after repeated osteosynthesis plus BMAC application without any consequences. Other than these 2 patients, no further complications were observed. In particular, no infections, no excessive new bone formation, no induction of

    Parenteral nutrition (PN) is a well-documented supportive care which maintains the nutritional status of patients. Clinical pharmacists are often involved in providing PN services; however, few studies have investigated the effect of a clinical pharmacy-based PN service in resource-limited settings. We designed a randomized clinical trial to compare the clinical pharmacist-based PN service (intervention group) with the conventional method (control group) for adult patients undergoing hematopoietic stem cell transplantation in Shariati Hospital, Tehran, Iran (2011-2012). In the intervention group, the clinical pharmacists implemented standard guidelines of nutrition support. The conventional method was a routine nutrition support protocol which was pursued for all patients in the bone marrow transplantation wards. Main study outcomes included nutritional status (weight, albumin, total protein, pre-albumin, and nitrogen balance), length of hospital stay, time to engraftment, rate of graft versus host disease, and mortality rate. Patients were followed for 3 months. Fifty-nine patients were randomly allocated to a study group. The overall intake (oral and parenteral) in the control group was significantly lower than standard daily needed calories (P nutritional outcomes were either preserved or improved in the intervention group while the nutritional status in the control group was deteriorated (P values nutrition support service significantly improved nutritional status and clinical outcomes in comparison with the suboptimal conventional method. Future studies should assess the cost effectiveness of clinical pharmacists' PN services.

  17. Neuromyelitis optica in an adolescent after bone marrow transplantation.

    Baumer, Fiona M; Kamihara, Junne; Gorman, Mark P

    2015-01-01

    Central nervous system complications of bone marrow transplant are a common occurrence and the differential diagnosis is quite broad, including opportunistic infections, medications toxicities, graft versus host disease, and other autoimmune processes. We summarize previously reported cases of autoimmune myelitis in post-transplant patients and discuss a 17-year-old boy who presented with seronegative neuromyelitis optica after a bone marrow transplant for acute myeloid leukemia. Our patient had a marked improvement in symptoms after plasmapheresis. Including our patient, there have been at least eight cases of post-transplant autoimmune myelitis presented in the literature, and at least three of these are suspicious for neuromyelitis optica. Several of these patients had poor outcomes with persistent symptoms after the myelitis. Autoimmune processes such as neuromyelitis optica should be carefully considered in patients after transplant as aggressive treatment like early plasmapheresis may improve outcomes.

  18. Intraventricular Transplantation of Autologous Bone Marrow Mesenchymal Stem Cells via Ommaya Reservoir in Persistent Vegetative State Patients after Haemorrhagic Stroke: Report of Two Cases & Review of the Literature

    Fauzi AA

    2016-11-01

    Full Text Available Background: One of the most devastating diseases, stroke, is a leading cause of death and disability worldwide with severe emotional and economic consequences. The purpose of this article is mainly to report the effect of intraventricular transplantation via an Ommaya reservoir using autologous bone marrow mesenchymal stem cells (BM-MSCs in haemorrhagic stroke patients. Case Presentations: Two patients, aged 51 and 52, bearing sequels of haemorrhagic stroke were managed by intraventricular transplantation of BM-MSCs obtained from their own bone marrow. Before the procedure, both patients were bedridden, tracheostomised, on nasogastric (NG tube feeding and in hemiparesis. The cells were transplanted intraventricularly (20 x 106 cells/2.5 ml using an Ommaya reservoir, and then repeated transplantations were done after 1 and 2 months consecutively. The safety and efficacy of the procedures were evaluated 3, 6 and 12 months after treatment. The National Institute of Health Stroke Scale (NIHSS was used to evaluate the patients' neurological status before and after treatment. No adverse events derived from the procedures or transplants were observed in the one-year follow-up period, and the neurological status of both patients improved after treatment. Conclusions: Our report demonstrates that the intraventricular transplantation of BM-MSCs via an Ommaya reservoir is safe and it improves the neurological status of post-haemorrhagic stroke patients. The repeated transplantation procedure is easier and safer to perform via a subcutaneously implanted Ommaya reservoir.

    Objective: To evaluate the utility of the inspiratory phase in high-resolution computed tomography (HRCT) of the chest for the diagnosis of post-bone marrow transplantation bronchiolitis obliterans. Materials and Methods: This was a retrospective, observational, cross-sectional study. We selected patients of either gender who underwent bone marrow transplantation and chest HRCT between March 1, 2002 and December 12, 2014. Ages ranged from 3 months to 20.7 years. We included all examinations in which the HRCT was performed appropriately. The examinations were read by two radiologists, one with extensive experience in pediatric radiology and another in the third year of residency, who determined the presence or absence of the following imaging features: air trapping, bronchiectasis, alveolar opacities, nodules, and atelectasis. Results: A total of 222 examinations were evaluated (mean, 5.4 ± 4.5 examinations per patient). The expiratory phase findings were comparable to those obtained in the inspiratory phase, except in one patient, in whom a small uncharacteristic nodule was identified only in the inspiratory phase. Air trapping was identified in a larger number of scans in the expiratory phase than in the inspiratory phase, as was atelectasis, although the difference was statistically significant only for air trapping. Conclusion: In children being evaluated for post-bone marrow transplantation bronchiolitis obliterans, the inspiratory phase can be excluded from the chest HRCT protocol, thus reducing by half the radiation exposure in this population.

    Of 320 patients receiving a marrow transplant at the Hospital de Sant Pau between 1986 and 1992, 12% developed viridans streptococcal bacteremia during severe neutropenia. Five of these patients (13%) developed a rapidly progressive fatal shock syndrome characterized by bilateral pulmonary infiltrates, acute respiratory failure (ARDS) and septic shock early in the transplantation course (6 or 7 days posttransplantation). All patients were transplanted for acute leukemia in remission, and 2 received an allogeneic and 3 an autologous transplant. Four of these subjects were younger than 15 years of age and all had received cyclophosphamide and total body irradiation as conditioning regimen for marrow transplantation. All 5 patients died, and postmortem examinations revealed diffuse pulmonary lesions characteristic of the ARDS. These observations contribute to defining the clinical and pathologic characteristics of this serious complication of intensive anticancer treatment.

    Six patients, aged 36 to 59 years, had heart transplants for terminal myocardial disease using total lymphatic irradiation (TLI) and donor bone marrow in addition to conventional therapy. All patients were poor candidates for transplantation because of marked pulmonary hypertension, unacceptable tissue matching, or age. Two patients are living and well more than four years after the transplants. Two patients died of infection at six and seven weeks with normal hearts. One patient, whose preoperative pulmonary hypertension was too great for an orthotopic heart transplant, died at 10 days after such a procedure. The other patient died of chronic rejection seven months postoperatively. Donor-specific tolerance developed in 2 patients. TLI and donor bone marrow can produce specific tolerance to donor antigens and allow easy control of rejection, but infection is still a major problem. We describe a new technique of administering TLI with early reduction of prednisone that may help this problem

  3. Autologous bone marrow mononuclear cell transplantation in patients with decompensated alcoholic liver disease: a randomized controlled trial.

    Laurent Spahr

    Full Text Available OBJECTIVE: Impaired liver regeneration is associated with a poor outcome in patients with decompensated alcoholic liver disease (ALD. We assessed whether autologous bone marrow mononuclear cell transplantation (BMMCT improved liver function in decompensated ALD. DESIGN: 58 patients (mean age 54 yrs; mean MELD score 19, all with cirrhosis, 81% with alcoholic steatohepatitis at baseline liver biopsy were randomized early after hospital admission to standard medical therapy (SMT alone (n = 30, including steroids in patients with a Maddrey's score ≥32, or combined with G-CSF injections and autologous BMMCT into the hepatic artery (n = 28. Bone marrow cells were harvested, isolated and reinfused the same day. The primary endpoint was a ≥3 points decrease in the MELD score at 3 months, corresponding to a clinically relevant improvement in liver function. Liver biopsy was repeated at week 4 to assess changes in Ki67+/CK7+ hepatic progenitor cells (HPC compartment. RESULTS: Both study groups were comparable at baseline. After 3 months, 2 and 4 patients died in the BMMCT and SMT groups, respectively. Adverse events were equally distributed between groups. Moderate alcohol relapse occurred in 31% of patients. The MELD score improved in parallel in both groups during follow-up with 18 patients (64% from the BMMCT group and 18 patients (53% from the SMT group reaching the primary endpoint (p = 0.43 (OR 1.6, CI 0.49-5.4 in an intention to treat analysis. Comparing liver biopsy at 4 weeks to baseline, steatosis improved (p<0.001, and proliferating HPC tended to decrease in both groups (-35 and -33%, respectively. CONCLUSION: Autologous BMMCT, compared to SMT is a safe procedure but did not result in an expanded HPC compartment or improved liver function. These data suggest either insufficient regenerative stimulation after BMMCT or resistance to liver regenerative drive in patients with decompensated alcoholic cirrhosis. TRIAL REGISTRATION

    Purpose: We have demonstrated that toxicities are acceptable with total marrow irradiation (TMI) at 16 Gy without chemotherapy or TMI at 12 Gy and the reduced intensity regimen of fludarabine/melphalan in patients undergoing hematopoietic cell transplantation (HCT). This article reports results of a study of TMI combined with higher intensity chemotherapy regimens in 2 phase I trials in patients with advanced acute myelogenous leukemia or acute lymphoblastic leukemia (AML/ALL) who would do poorly on standard intent-to-cure HCT regimens. Methods and Materials: Trial 1 consisted of TMI on Days -10 to -6, etoposide (VP16) on Day -5 (60 mg/kg), and cyclophosphamide (CY) on Day -3 (100 mg/kg). TMI dose was 12 (n=3 patients), 13.5 (n=3 patients), and 15 (n=6 patients) Gy at 1.5 Gy twice daily. Trial 2 consisted of busulfan (BU) on Days -12 to -8 (800 {mu}M min), TMI on Days -8 to -4, and VP16 on Day -3 (30 mg/kg). TMI dose was 12 (n=18) and 13.5 (n=2) Gy at 1.5 Gy twice daily. Results: Trial 1 had 12 patients with a median age of 33 years. Six patients had induction failures (IF), and 6 had first relapses (1RL), 9 with leukemia blast involvement of bone marrow ranging from 10%-98%, 5 with circulating blasts (24%-85%), and 2 with chloromas. No dose-limiting toxicities were observed. Eleven patients achieved complete remission at Day 30. With a median follow-up of 14.75 months, 5 patients remained in complete remission from 13.5-37.7 months. Trial 2 had 20 patients with a median age of 41 years. Thirteen patients had IF, and 5 had 1RL, 2 in second relapse, 19 with marrow blasts (3%-100%) and 13 with peripheral blasts (6%-63%). Grade 4 dose-limiting toxicities were seen at 13.5 Gy (stomatitis and hepatotoxicity). Stomatitis was the most frequent toxicity in both trials. Conclusions: TMI dose escalation to 15 Gy is possible when combined with CY/VP16 and is associated with acceptable toxicities and encouraging outcomes. TMI dose escalation is not possible with BU/VP16 due to

    Severe combined immunodeficiency (SCID) was diagnosed in a girl immediately after birth; her older brother had SCID and was successfully reconstituted by bone marrow transplantation from his uncle. She was isolated in a laminar air flow bench and decontaminated. The father differed by one HLA......-A antigen but was HLA-Dw2 homozygous like the patient; his lymphocytes showed a slight response to the patient's cells in mixed lymphocyte culture (MLC). At the age of 2 1/2 months and again at 5 months, she was given a bone marrow transplant from the father. During the entire course the patient had...

  6. Impact of laser therapy on the condition of oral cavity mucosa in chemotherapy treated patients who underwent bone marrow transplantation

    Full Text Available Patological disorders within oral mucosa (so called mucositis are the most common stomatological complications among chemotherapy treated leukemic patients scheduled for bone marrow transplantation. Early diagnosis of such oral disorders leads to numerous side effects, decreasing quality of life and systemic complications is required. Furthermore, most patients require analgesic treatment, very often using narcotic pain medications. Presently the largest role of prevention and treatment of mucositis is preventative dentistry along with maintaining strict oral hygiene. This course of action aims to reduce pain and prevention of infections. Investigation of novel non-invasive therapeutic methods that could improve treatment outcomes seems justified. Among the most promising methods, the Low-level Laser Therapy (LLLT treatment demonstrates many beneficial effects for patients suffering from chemotherapy complications. It promotes mucosal healing and helps improve patients' quality of life. These advantages may be a result of a LLLT anti-inflammatory and analgesic effect. LLLT also promotes tissue regeneration through chemical changes in cells (cell repair. In recent clinical studies conducted on a group of patients with oral mucositis, the significant acceleration of mentioned disorders regression was noted. Moreover, reduction of pain after application of LLLT was recorded. Discussed in the article LLLT is easily accessible for clinical practice . Mentioned arguments justify a wider use of such a tool in non-invasive treatment of acute oral cavity inflammation.

    The kinetics and biodistribution of HLA identical In-111 labeled platelets was studied in 10 leukemic patients with bone marrow transplants refractory to HLA matched platelet transfusions. Platelet survival time was short (x-bar +- SEM =1.64 +- 0.83 days). The mean recovery (extrapolated to zero time) was 29.9%, ranging from 14.2 to 63.0%. The deposition of the In-111 platelets in the liver and spleen was quantified by the geometric mean method using anterior and posterior imaging. In 3 patients liver uptake was significantly increased. The highest hepatic accumulation of In-111 occurred 2 hrs after injection (x-bar=76 +- 6% dose (SEM); at 48 hrs 62% of the dose remained in the liver. In 7 patients the spleen was the organ with the highest labeled platelet deposition. The splenic uptake of In-111 platelets in this group correlated with the spleen size (r=+0.95). At 30 min after injection 75+-6% of the dose was found in the spleen. Splenic activity decreased to 62% after 48 hrs. At the same time, In-111 liver accumulation increased from 14 to 31%. This finding suggests that In-111 may be released from the spleen and subsequently sequestered by the liver. Two patients with high splenic uptake underwent splenectomy after the In-111 platelet study. Both benefited from splenectomy in terms of platelet survival after transfusion

  10. Bone marrow transplantation for treatment of radiation disease. Problems involved

    Fliedner, T.M.

    1992-01-01

    Transplantation of bone marrow cells still is one of the major means available for treatment of radiation injuries. The decisive indication is the diagnostic of irreversible damage to the hemopoietic stem cells, which becomes manifest about 5 or 6 days after exposure, by severe granulocytopenia and simultaneous, progressive thrombopenia. The radiation dose provoking such severe injury is estimated to be at least 9-10 Gy of homogeneous whole-body irradiation. Preparatory measures for transplantation include proof of tissue compatibility of donor and patient, sufficient immunosuppression prior to and/or after irradiation and bone marrow transplantation. The donor's marrow should be free of T-cells. In spite of preparatory treatment, complications such as immunological reactions or disturbance of organ functions are to be very probable. These are treated according to therapy protocols. (orig./MG) [de

  12. Total body irradiation in bone marrow transplantation

    Gluckman, E.; Devergie, A.; Boiron, M.; Bernard, Jean; Dutreix, A.; Dutreix, J.

    1979-01-01

    Total body irradiation was used in 22 patients as part of their conditioning regimen for bone marrow transplantation. Nine patients with acute leukemia received 1000 cGy TBI in addition with chemotherapy. None of them survived and the main cause of death was interstitial pneumonitis (50%). 4 patients received 1000 cGy with a lung shielding of 500 cGy. Two patients with acute leukemia died of leukemia and sepsis, two patients had aplastic anemia, one is surviving, the other died of severe GVHD and infectious complications. Nine patients with severe aplastic anemia strongly immunized by previous blood transfusions received 800 cGy TBI with a lung shielding of 400 cGy. No rejection was observed and 7 patients (63%) are currently alive. One patient died of interstitial pneumonitis probably related to CMV infection, one of subacute necrotizing hepatitis, two of severe acute GVHD. It is concluded from this study that TBI remains the best immunosuppressive conditioning regimen even in strongly immunized patients. It may be a contributing factor of the incidence and severity of interstitial pneumonitis. A reduction of the dose of the lung to 400-500 cGy seems to decrease the severity of this complication

    Mucormycosis is a fatal complication in immunocompromised patients, and is additionally difficult to diagnose due to the lack of useful serum biomarkers. Using a quantitative PCR approach, we retrospectively analyzed Mucorales DNA load in sera collected serially from a 3-year-old patient with chronic granulomatous disease, who died of multi-organ failure probably due to dissemination of Rhizomucor pusillus, which was detected from necropsy specimens. Mucorales DNA load was below the detection limit on days 9, 2, and 4 after unrelated bone marrow transplantation. Rhizomucor DNA was first detected on day 14 (1.6 × 10(3) copies/mL), and subsequently fluctuated between 1.3 × 10(3) and 37.2 × 10(3) copies/mL until day 43. Rhizomucor achieved a peak value of 940.0 × 10(3) copies/mL on day 48 the day before death. The detection or fluctuation of Rhizomucor DNA appeared to be associated with corticosteroid dosages or C-reactive protein levels. This specific, noninvasive, and highly quantitative assay may be useful for the early diagnosis of mucormycosis and prediction of disease progression.

    Full Text Available Background: Bone Marrow Transplantation is one of the most important therapeutic methods in much malignant and nonmalignant disease. Patients with Bone Marrow Transplantation (BMT following radiotherapy and chemotherapy will suffer from immuno-suppression. Therefore they are susceptible to get saprophytic fungi infection that sometimes are killer. Materials and Methods: The purpose of this cross-sectional survey is isolation of saprophytic fungi from patients with BMT and wards space and instruments. Therefore sampling from ventilator system (HEPA filter and common filter, air canal, air, hospital instruments and clinical samples (nasal discharge, sputum, urine were done and cultured in sabouro dextrose agar with choloramphenicol (SC. In assessing total frequency from 4838 plates of wards space and instruments, 985 fungi colonies includes 21 genus were isolated. Results and Conclusion: Most fungi colonies present were Penicillium , Aspergillus and Cladosporium and low present were Trichoderma ,Stereptomyses, Chrysosporium, Rhizopus.

    The authors present some results from their experiments on bone-marrow storage and transplantation. The main problems with preservation of stored bone marrow are the duration, temperature, adjuvant substances and the significance of viability tests during the conservation processes. The results showed that: Bullet Storage of bone marrow at +4eC produces a progressive decrease in its restoring capacity versus storage time. Bullet While bone marrow stored for 24 h is able to restore 100% of dogs lethally irradiated with 600 rad, after 10 days of storage only 20% of the animals can be restored. Bullet No correlation exists between the actual survival of dogs and that calculated by dye exclusion tests, which indicate a rather high (70%) viability, even after 10 days bone-marrow storage at +4 Degree-Sign C. Bullet DNA degradation (depolymerization) measurements of the bone marrow may be used as a supplementary test for checking the viability or restoration potency of bone-marrow cells after storage. Bullet In the freezing process, the optimum contact time between glycerol and the bone-marrow cells is 15 min. Results of experiments regarding certain bone-marrow transplantation problems showed that: Bullet The best time to administer bone marrow is between 24 and 48 h after irradiation. Bullet No survivors were obtained with dogs lethally irradiated with 600 rad by administering autogenic or allogenic DNA extracted from bone marrow, spleen or liver. Bullet Histocompatibility related to sex may play an important role in the bone-marrow graft. The lowest survival of C57BL mice was obtained when the donors were males and the recipients females. Bullet In radioprotection with foetal haemocytopoietic tissues, the donor's age represents one of the main factors. The best results were obtained in experiments on rats, with 19- to 20-day foetal liver (period of complete and maximum haemocytopoietic activity).

  17. Tetanus after allogeneic bone-marrow transplantation

    Kendra, J.R.; Halil, O.; Barrett, A.J.; Selwyn, S.

    1982-01-01

    A brief report is presented of a case of tetanus after allogeneic bone-marrow transplantation complicated by radiation-induced pneumonitis. A 30-year-old army sergeant received a bone-marrow transplant from his brother for the treatment of a granulocytic sarcoma after local radiotherapy to the tumour. Six years earlier he had sustained an open, compound fracture of the left tibia and fibula while on army exercise. At the time a pin and plate had been inserted and booster anti-tetanus administered. Bone-marrow transplantation was performed after total body irradiation. Cyclosporin A was given against graft-versus-host disease. Fifty four days after transplantation tetanus was diagnosed and death followed 14 days later. Necropsy disclosed radiation-induced pneumonitis, but no organisms were cultured from the lungs or the old fracture site. It is suggested that spores were incorporated into the wound site before surgery and that oxygenation around the plate became compromised after transplantation, permitting germination of dormant spores, immunosuppression allowing development of the disease.

  18. Growth in children following irradiation for bone marrow transplantation

    Bushhouse, S.; Ramsay, N.K.; Pescovitz, O.H.; Kim, T.; Robison, L.L.

    1989-01-01

    Longitudinal height data from 46 pediatric bone marrow transplant (BMT) patients, including 18 with aplastic anemia (AA), 19 with acute nonlymphoblastic leukemia (ANLL), and 9 with acute lymphoblastic leukemia (ALL), were analyzed to assess growth posttransplantation. Patients were prepared for BMT with high-dose cyclophosphamide followed by 7.5 Gy single-dose irradiation; AA patients received total lymphoid irradiation (TLI), and leukemia patients received total body irradiation (TBI). AA patients demonstrated reduced height posttransplant as reflected in a negative mean standard deviation score. The observed reduction was statistically significant only at 3 years following transplant. In contrast, leukemia patients showed a significant loss in relative height that was first visible at 1 year post-BMT and continued until at least 4 years post-BMT. Mean growth velocities in the leukemia patients were significantly below median for the 3 years following transplant. With a median follow-up of 4 years, antithymocyte globulin plus steroids in combination with methotrexate as graft vs. host prophylaxis was associated with less severe growth suppression than methotrexate alone, while there were no significant associations between growth during the first 2 years following transplant and prepubertal status at transplant (as defined by age), graft vs. host disease, thyroid or gonadal function, or previous therapies received by the leukemia patients. Children undergoing marrow transplantation, particularly those receiving TBI, are at significant risk of subsequent growth suppression

  19. Splenic irradiation before bone marrow transplantation for chronic myeloid leukaemia

    Gratwohl, A.; Hermans, J.; Biezen, A.V.

    1996-01-01

    A total of 229 patients with chronic myeloid leukaemia (CML) in chronic phase were randomized between 1986 and 1990 to receive or not receive additional splenic irradiation as part of their conditioning prior to bone marrow transplantation (BMT). Both groups, 115 patients with and 114 patients without splenic irradiation, were very similar regarding distribution of age, sex, donor/recipient sex combination, conditioning, graft-versus-host disease (GvHD) prevention method and blood counts at diagnosis or prior to transplant. 135 patients (59%) are alive as of October 1995 with a minimum follow-up of 5 years. 52 patients have relapsed (23%), 26 patients in the irradiated, 26 patients in the non-irradiated group (n.s.) with a relapse incident at 6 years of 28%. The main risk factor for relapse was T-cell depletion as the method for GvHD prevention, and an elevated basophil count in the peripheral blood prior to transplant. Relapse incidence between patients with or without splenic irradiation was no different in patients at high risk for relapse, e.g. patients transplanted with T-cell-depleted marrows (P = n.s.) and in patients with low risk for relapse, e.g. patients transplanted with non-T-cell-depleted transplants and basophil counts 3% basophils in peripheral blood). In this patient group, relapse incidence was 11% at 6 years with splenic irradiation but 32% in the non-irradiated group (P = 0.05). Transplant-related mortality was similar whether patients received splenic irradiation or not. This study suggests an advantage in splenic irradiation prior to transplantation for CML in this subgroup of patients and illustrates the need for tailored therapy. (Author)

  20. Serum carnitine levels in bone marrow transplant recipients.

    Kirvelä, O; Antila, H; Heinonen, O; Toivanen, A

    1990-12-01

    This study investigated plasma carnitine levels in patients undergoing allogenic bone marrow transplantation. The patients received fat-based TPN (50% fat, 50% CHO; calorie: nitrogen ratio 125:1) for an average of 33 +/- 7.5 days. TPN was started before transplantation and stopped when patients were able to eat. Caloric needs were estimated using the Harris-Benedict equation; 150% of the estimated BEE was given for the first two weeks after transplantation. The amount of TPN was gradually decreased as patients resumed their oral intake. All patients had low-normal serum carnitine levels before transplantation. There was no significant change in total or free serum carnitine levels during the course of TPN. However, in patients who had symptoms of graft vs. host reaction (GVH), the highest carnitine values during GVH (total 72.3 +/- 6.5 and free 61.2 +/- 12.4 mumol/l) were significantly higher (p < 0.001) than the baseline values (total 27.1 +/- 9.3 and free 24.9 +/- 9.6 mumol/l) or the highest non GVH values after transplantation (total 32.0 +/- 10.7 and free 29.0 +/- 10.7 mumol/l, respectively). The serum triglyceride, total cholesterol, and HDL cholesterol remained within normal range. In conclusion, bone marrow transplant patients receiving fat-based TPN have normal circulating levels of carnitine. GVH reaction caused an increase in the carnitine levels, which was probably due to increased tissue catabolism.

  1. Total body irradiation in bone marrow transplantation: the influence of fractionation and delay of marrow infusion

    Lichter, A.S.; Tracy, D.; Lam, W.C.; Order, S.E.

    1980-01-01

    Bone marrow transplantation (BMT) after total body irradiation (TBI) and cyclophosphamide is being employed increasingly in the therapy of end stage leukemia. Interstitial pneumonitis (IP) represents a major acute toxicity after allogeneic transplantation. A more rapid reconstitution of lymphoid organs and bone marrow post transplant may result in increased immune competence and hence fewer opportunistic pulmonary infections and IP. By delaying the infusion of marrow to 72 hr after TBI (1250 rad at 7.5 rad/min) instead of the customary 24 hr, we can demonstrate an increase in initial repopulation of thymus, spleen and bone marrow, with syngeneic transplants in Lewis rats. Interstitial pneumonitis may also be caused, in part, by the pulmonary toxicity of large single exposures of TBI. Clinical and laboratory data suggest that fractionated TBI may be less toxic to the lung. When fractionated TBI (625 rad x 2, 7.5 rad/min) is compared to single dose TBI (1250 rad, 7.5 rad/min), and increased initial repopulation of lymphoid organs is observed when fractionated therapy is employed. Delay in marrow infusion and fractionation of TBI exposure may have clinical advantages in patients who receive BMT

  2. Effect of nephrotoxic drugs on the development of radiation nephropathy after bone marrow transplantation

    Lawton, C.A.; Fish, B.L.; Moulder, J.E.

    1994-01-01

    Chronic renal failure is a significant cause of late morbidity in bone marrow transplant patients whose conditioning regimen includes total body irradiation (TBI). Radiation is a major cause of this syndrome (bone marrow transplant nephropathy), but it may not be the only cause. These studies use a rat syngeneic bone marrow transplant model to determine whether nephrotoxic agents used in conjunction with bone marrow transplantation (BMT) could be enhancing or accelerating the development of radiation nephropathy. Rats received 11-17 Gy TBI in six fractions over 3 days followed by syngeneic bone marrow transplant. In conjunction with the bone marrow transplants, animals received either no drugs, cyclosporine, amphotericin, gentamicin, or busulfan. Drugs were given in schedules analogous to their use in clinical bone marrow transplantation. Drug doses were chosen so that the drug regimen alone caused detectable acute nephrotoxicity. Animals were followed for 6 months with periodic renal function tests. Gentamicin had no apparent interactions with TBI. Amphotericin increased the incidence of engraftment failure, but did not enhance radiation nephropathy. Cyclosporin with TBI caused late morbidity that appeared to be due to neurological problems, but did not enhance radiation nephropathy. Busulfan resulted in a significant enhancement of radiation nephropathy. Of the nephrotoxins used in conjunction with bone marrow transplantation only radiation and busulfan were found to be risk factors for bone marrow transplant nephropathy. 34 refs., 4 figs., 2 tabs

    Until recently long-term renal toxicity has not been considered a major late complication of bone marrow transplantation (BMT). Late renal dysfunction has been described in a pediatric population status post-BMT which was attributable to the radiation in the preparatory regimen. A thorough review of adults with this type of late renal dysfunction has not previously been described. Fourteen of 103 evaluable adult patients undergoing allogeneic (96) or autologous (7) bone marrow transplantation, predominantly for leukemia and lymphomas, at the Medical College of Wisconsin (Milwaukee, WI) have had a syndrome of renal insufficiency characterized by increased serum creatinine, decreased glomerular filtration rate, anemia, and hypertension. This syndrome developed at a median of 9 months (range, 4.5 to 26 months) posttransplantation in the absence of specific identifiable causes. The cumulative probability of having this renal dysfunction is 20% at 1 year. Renal biopsies performed on seven of these cases showed the endothelium widely separated from the basement membrane, extreme thickening of the glomerular basement membrane, and microthrombi. Previous chemotherapy, antibiotics, and antifungals as well as cyclosporin may add to and possibly potentiate a primary chemoradiation marrow transplant renal injury, but this clinical syndrome is most analogous to clinical and experimental models of radiation nephritis. This late marrow transplant-associated nephritis should be recognized as a potentially limiting factor in the use of some intensive chemoradiation conditioning regimens used for BMT. Some selective attenuation of the radiation to the kidneys may decrease the incidence of this renal dysfunction

    Longitudinal data were analysed on the lung function of 25 of 29 survivors of childhood leukaemia or lymphoma, who had been conditioned with cyclophosphamide and total body irradiation before allogeneic bone marrow transplantation, to test whether children are particularly vulnerable to pulmonary...... damage after transplantation. None developed chronic graft-versus-host disease. Transfer factor and lung volumes were reduced immediately after bone marrow transplantation, but increased during the following years. However, at the last follow up, 4-13 years (median 8) after transplantation, patients had...... to their age at bone marrow transplantation. In conclusion, patients had subclinical restrictive pulmonary disease at a median of eight years after total body irradiation and allogeneic bone marrow transplantation....

  6. Total body irradiation as a form of preparation for bone marrow transplantation

    Inoue, Toshihiko

    1987-01-01

    The history of total body irradiation and bone marrow transplantation is surprisingly old. Following the success of Thomas et al. in the 1970s, bone marrow transplantation appeared to be the sole curative treatment modality for high-risk leukemia. A supralethal dose of total body irradiation was widely accepted as a form of preparation for bone marrow transplantation. In this paper, I described the present status of bone marrow transplantation for leukemia patients in Japan based on the IVth national survey. Since interstitial pneumonitis was one of the most life threatening complications after bone marrow transplantation, I mentioned the dose, dose-rate and fraction of total body irradiation in more detail. In addition, I dealt with some problems of the total body irradiation, such as dose prescription, compensating contour as well as inhomogeneity, and shielding for the highrisk organs.

    Full Text Available The introduction of peripheral stem cell (PSC and cord blood (CB as an alternative to bone marrow (BM recently has caused important changes on hematopoietic stem cell transplantation (HSCT practice. According to the CIBMTR data, there has been a significant decrease in the use of bone marrow and increase in the use of PSC and CB as the stem cell source for HSCT performed during 1997–2006 period for patients under the age of 20. On the other hand, the stem cell source in 70% of the HSCT procedures performed for patients over the age of 20 was PSC and the second most preferred stem cell source was bone marrow. CB usage is very limited for the adult population. Primary disease, stage, age, time and urgency of transplantation, HLA match between the patient and the donor, stem cell quantity, and the experience of the transplantation center are some of the associated factors for the selection of the appropriate stem cell source. Unfortunately, there is no prospective randomized study aimed to facilitate the selection of the correct source between CB, PSC, and BM. In this paper, we would like to emphasize the data on stem cell selection in light of the current knowledge for patient populations according to their age and primary disease.

    Intermediate-risk cytogenetic acute myeloid leukemia with an internal tandem duplication of FLT3 ( FLT3 -ITD) is associated with a high risk of relapse, and is now a standard indication for allogeneic stem cell transplantation. Nevertheless, most studies supporting this strategy have been performed in young patients. To address the benefit of allogeneic transplantation in the elderly, we made a selection from the European Society for Blood and Marrow Transplantation registry of de novo intermediate-risk cytogenetic acute myeloid leukemia harboring FLT3 -ITD in patients aged 60 or over and transplanted from a related or unrelated donor between January 2000 and December 2015. Two hundred and ninety-one patients were identified. Most patients received a reduced-intensity conditioning (82%), while donors consisted of an unrelated donor in 161 (55%) patients. Two hundred and twelve patients received their transplantation in first remission, 37 in second remission and 42 in a more advanced stage of the disease. The 2-year leukemia-free survival rate was 56% in patients in first remission, 22% in those in second remission and 10% in patients with active disease, respectively ( P <0.005). Non-relapse mortality for the entire cohort was 20%. In multivariate analysis, disease status at transplantation was the most powerful predictor of worse leukemia-free survival, graft- versus -host disease and relapse-free survival, and overall survival. In this elderly population, age was not associated with outcome. Based on the current results, allogeneic transplantation translates into a favorable outcome in fit patients ≥ 60 with FLT3 -ITD acute myeloid leukemia in first remission, similarly to current treatment recommendations for younger patients.

    1999-02-01

    We report the therapeutic results of allogeneic bone marrow transplantations (BMT) for 16 children with high-risk leukemia and lymphoma. The conditioning regimen consisted of total body irradiation (TBI) (12 Gy), busulfan (Bu) (4 mg/kg x 2 days), and melphalan (L-PAM) (70 mg/m{sup 2} x 2 or 3 days). Graft-versus-host disease (GVHD) prophylaxis was performed with cyclosporin (CsA) + methotrexate (MTX) (4 cases) and CsA + MTX-methyl-prednisolone (11 cases). Seven patients had acute lymphocytic leukemia, 6 acute nonlymphocytic leukemia, 2 B-cell type non-Hodgkin`s lymphoma, and 1 peripheral T-cell lymphoma. Nine patients were in complete remission (CR) and 7 in non CR at BMT. Nine patients received transplants from HLA-matched related (MR) donors, 4 from HLA-mismatched related (MisR) donors, and 3 from unrelated (UR) donors. Seven of the cases, all of which were transplanted from MR, have continued complete remission for 15-47 (median 27) months. Nine patients, of which seven were transplanted from MisR/UR, died from complications from fungal pneumonia (3), cytomegalovirus pneumonitis (1), GVHD (1), rhabdomyolysis (1), lymphoproliferative disorder (1), rejection (1), and relapse (1). These results suggest that the combination of TBI, Bu, and L-PAM as a BMT regimen has a significant anti-neoplastic benefit and is considered to be useful; however, considering the high rate of fatal transplant-related complications, more refinement is required, especially for transplants from MisR and UR donors.

  14. Allogeneic bone marrow transplantation with conditioning regimen to total body irradiation + thiotepa + melphalan for 35 patients with high-risk leukemia

    Yumura-Yagi, Keiko; Inoue, Masami; Okamura, Takayuki

    1997-01-01

    Thirty-five children with high-risk leukemia received an allogeneic bone marrow transplantation (BMT) following a pre-conditioning regimen consisting of total body irradiation, thiotepa and melphalan. Twenty-one patients had acute lymphocytic leukemia, 6 acute nonlymphocytic leukemia, 2 acute undifferentiated leukemia, 2 acute mixed lineage leukemia, 2 myelodysplastic syndrome and 2 juvenile chronic myeloid leukemia. Sixteen patients received BMT while in complete remission (CR), but 19 were not in CR. Eighteen patients received transplants from HLA-matched related donors, 15 from unrelated donors and 2 from HLA-mismatched related donors. Cyclosporin±methotrexate was used for graft-versus-host disease (GVHD) prophylaxis in the BMTs from related donors and tacrolimus±prednisolone in the BMTs from unrelated donors. Transplant-related death occurred in 12 patients; 5 acute GVHD, 4 infections (3 fungal infections, 1 Cytomegalovirus pneumonia), 1 intracranial haemorrhage and 2 chronic GVHD. Relapses were observed in 6 patients (69, 168, 175, 222, 275 and 609 days post BMT). Event-free survival rate at 2 years is 38.1% in CR patients and 36.9% in nonCR patients. (author)

  15. Bone marrow transplantation in Japan

    BMT in Japan was started in 1975. From 1981 Japan BMT study group was organized by the grant of ministry of health and welfare Japan. A rapid increase of number of BMT parallel to the improvement of results was observed in the 489 patients by the registry of this group. The major causes of failure of BMT were interstitial pneumonitis (IP), relapse of leukemia, infection, and graft versus host disease (GVHD). The incidence of IP decreased very rapidly by fractionation of total body irradiation and anti-cytomegalovirus (CMV) antibody negative platelet transfusion. Prophylactic administration of anti-CMV immunoglobulin produced also significant reduction of IP. In the double blind controled study oral administration of aciclovir revealed significant reduction of herpes stomatitis, followed by the reduction of other infections including sepsis. For the decontamination of bioclean room we have developed ozone decontamination, which revealed to be very effective for fungus. Colony stimulating factor was found to shorten the period of granulocytopenia. The patients with GVHD showed lower incidence of relapse of leukemia than those without GVHD. In the patients who received BMT during their first remission of ALL. Long survival rate was 63 %, for ANLL in the first remission, 64 % and for CML in the chronic phase, 40 %. Out of the first 20 BMT patients of the center for adult diseases Osaka, only three are living now, while out of the next 25 patients 22 are living disease free. Major items of modification of BMT procedures between those two groups were cyclosporine A, colony stimulating factor, fractionated TBI, CMV-negative platelet donar, BMT in first remission for acute leukemia or chronic phase in CML. BMT seemed to be a very reliable and promising treatment of leukemia with a very high possibility of complete cure. (author)

    Illness-induced disruptions to lifestyles, activities, and interests (i.e., illness intrusiveness) compromise subjective well-being. The authors measured illness intrusiveness in autologous blood and bone marrow transplantation (ABMT) survivors and compared the results with survivors of solid organ transplants. Forty-four of 64 consecutive ABMT survivors referred to the University of Toronto ABMT long-term follow-up clinic completed the Illness Intrusiveness Ratings Scale (IIRS), the Affect Balance Scale (ABS), the Atkinson Life Happiness Rating (ATKLH), the Beck Hopelessness Scale (BHS), and the Center for Epidemiologic Studies Depression (CES-D) Scale. Mean time from ABMT to evaluation was 4.6 +/- 2.8 years. All patients were in remission or had stable disease at the time of evaluation. Autologous blood and bone marrow transplantation patients' IIRS scores were compared with scores reported by recipients of kidney (n = 357), liver (n = 150), lung (n = 77), and heart (n = 60) transplants. Mean IIRS score for the 44 ABMT patients was 37.2 +/- 17 (maximum possible score, 91; minimum possible score, 13). Higher IIRS scores correlated with lower scores on the ABS (r = -0.54; P work, financial situation, and active recreation. Despite achieving a remission after ABMT, patients continue to experience illness intrusiveness compromising subjective well-being. Copyright 2001 American Cancer Society.

  17. N-methylnicotinamide as a possible prognostic indicator of recovery from leukaemia in patients treated with total-body irradiation and bone marrow transplants

    Tamulevicius, P; Streffer, C

    1984-04-01

    N-methylnicotinamide was determined in urine from patients with acute myelocytic leukaemia following total-body X-irradiation with 8.6 Gy and bone marrow transplantation. Patients that are alive and in excellent condition i.e. with acute leukaemia in full remission showed a distinct enhanced excretion of this metabolite about 20 days p.r. which returned to normal levels at about day 40 p.r. Patients that have died intercurrently of early leukaemic recurrences showed considerable fluctuations in N-methylnicotinamide excretion over the entire period and no ''normalization'' of levels in these patients was seen. In those cases where late leukaemic recurrence or infections were the cause of death, usually after discharge from the clinic, excretion patterns typical of those seen in disease-free patients were observed. We thus conclude that this metabolite appears to be a suitable tentative prognostic indicator for the overall state of recovery from leukaemia in the patients.

    Objectives: Allogeneic bone-marrow transplantation (BMT) is an established treatment for many haematological malignancies. Unfortunately, most patients lack an HLA geno typically identical sibling and require an alternative donor, such as an HLA-haploidentical mismatched related donor, an HLA phenotypically matched or partially mismatched unrelated donor or an HLA-similar cord blood stem cell donor. However, these types of BMT increase the risk of graft-versus-host disease (GvHD), graft failure, delayed immuno reconstitution and fatal infection that observed after a sibling matched donor. Many centers are exploring the possibility of using donors other than matched sibling. Our approach has been to employ T-cell depleted mismatched haploidentical familial donor BMT to solve the problem of GvHD, a highly immuno- and myelo-suppressive conditioning regimen to reduce the incidence of graft failure and relapse, a graft inoculum plus G-CSF donor mobilized peripheral blood stem cells (PBSC) to overcome the host-versus-graft barrier. Patients and methods: Thirty-six patients (25 male, 11 female; median age 22 years, range 2-51) were treated with an allogeneic T-depleted haploidentical three loci mismatched bone-marrow and G-CSF mobilized PBSC transplantation from a familiar donor (18 siblings, 17 parents and 1 cousin) between March 1993 and June 1995. All had high-risk or advanced stage acute myeloid (12) or acute lymphoid (24) leukaemia; 18 were in haematological complete remission (CR) and 18 in chemo resistant relapse. Patients were conditioned with 8 Gy single dose TBI administered on day -5 at an instantaneous dose-rate of 13.4-31.7 cGy/min/midplane and average of 6.7-12.12 cGy/min/midplane. Shields were used to reduce the lung dose to 7 Gy in the first 23 cases and to 6 Gy in the last 13. 10 mg/Kg thiotepa were administered on day -4, 5 mg/Kg rabbit ATG from day -4 to day -1, 60 or 50 mg/Kg/cyclophosphamide on days -3 and -2. Bone-marrow and PBSC were infused on day

  19. Late taste disorders in bone marrow transplantation: clinical evaluation with taste solutions in autologous and allogeneic bone marrow recipients.

    1991-01-01

    The aim of this work was to determine the type and the significance of taste disorders in allogeneic bone marrow transplanted patients. In a retrospective study the taste threshold of a cohort of 15 allogeneic bone marrow transplanted patients, 4-51 months after transplantation (mean: 30.6 +/- 15.8), was compared to the taste threshold of 8 autologous bone marrow recipients, 4-48 months after transplantation (mean: 24.12 +/- 12.18), and to the taste threshold of a group of 20 consecutive normal subjects. Allogeneic bone marrow transplanted patients showed a significant hypogeusia for salt (Pearson's chi square p = 0.0002; Yates' correction p = 0.0007) and sour (Pearson's chi square p = 0.001; Yates' correction p = 0.008). No significant variations were observed for sweet and bitter. Autologous bone marrow recipients did not show any significant variation of taste acuity for sweet, salt or sour; a constant reduction of the taste threshold for bitter was observed, but the values were not significantly different from normal (Pearson's chi square p = 0.47; Yates' correction p = 0.83). So, late and selective taste disorders are observed in allogeneic bone marrow transplanted patients. Since the severity of the disorders is not strictly related to the severity of chronic oral G.V.H.D., taste analysis could discover the slightest, clinically undetectable cases of chronic oral G.V.H.D. The mechanism of immune aggression on the sensorial taste cells is poorly understood. Further trials are needed to define variations of taste acuity not only after allogeneic bone marrow transplantation, but also in systemic immune diseases.

    Laminar air flow isolation and decontamination procedures were evaluated in a prospective randomized study in patients with aplastic anemia or acute leukemia undergoing marrow transplantation from HLA-matched siblings. Patients transplanted in the laminar air flow group had significantly less septicemia and major local infections than did patients in the control group. Nineteen of 46 laminar air flow patients and six of 44 control patients are alive at present. In patients with aplastic anemia the survival was 13 of 17 in the laminar air flow group compared with four of 17 in the control group. In patients with acute leukemia the survival was six of 29 in the laminar air flow group versus two of 27 in the control group. These differences were not statistically significant. Death in both the laminar air flow and control groups was predominantly due to interstitial pneumonitis or recurrent leukemia, which were unaffected by isolation and decontamination

    2016-06-01

    Full Text Available Infections in immunocompromised patients after hematopoietic stem cell transplantation can have a severe and atypical course. Some opportunistic pathogens are difficult to detect in microbiological tests, and that is why treatment success depends on an accurate clinical diagnosis. This article presents a case of a 7-year-old girl with severe aplastic anemia treated with bone marrow transplantation with post-transplantation period complicated by persistent, hectic fever, with peak episodes of 39–40°C, lasting several weeks. Repeated microbiological tests failed to reveal the etiological agent, and empirical anti-infective treatment was ineffective. In the fourth week of fever, imaging showed multiple foci resembling abscesses in the patient’s internal organs and, subsequently, in soft tissues. The characteristics of these changes and data concerning environmental exposure led to the clinical diagnosis of cat scratch disease (bartonellosis with multi-organ involvement and enabled the targeted treatment to be implemented. Fever subsided and organ lesions regressed. In this case, repeated ultrasound imaging was the basic diagnostic tool that helped arrive at a correct diagnosis and implement effective treatment of this life-threatening complication after hematopoietic stem cell transplantation.

    Leukocyte Adhesion Deficiency type-I (LAD-I) is a rare autosomal recessive immunodeficiency syndrome leading recurrent bacterial and fungal infections. Bone marrow transplantation offers the only cure. In this report, we describe the course and outcome of bone marrow transplant in a 4-month-old female infant with LAD-I at King Hussein Medical Center, Jordan. A successful matched HLA-I related allogeneic bone marrow transplantation was performed. Engraftment was demonstrated on the 12th day. The patient developed GradeIII grafts versus host disease (GVHD), veno-occlusive disease of the liver and late onset hemorrhagic cystitis. She recovered with appropriate immune reconstitution.

  4. Radiation nephritis following total-body irradiation and cyclophosphamide in preparation for bone marrow transplantation

    Bergstein, J.; Andreoli, S.P.; Provisor, A.J.; Yum, M.

    1986-01-01

    Two children prepared for bone marrow transplantation with total-body irradiation and cyclophosphamide developed hypertension, microscopic hematuria, proteinuria, diminished renal function, and anemia six months after transplantation. Light microscopy of the kidneys revealed mesangial expansion, glomerular capillary wall thickening, and lumenal thrombosis. Electron microscopy demonstrated widening of the subendothelial space due to the deposition of amorphous fluffy material. In one patient, immunofluorescence microscopy revealed glomerular capillary wall deposition of fibrin and immunoglobulins. The clinical and histologic findings support the diagnosis of radiation nephritis. Patients prepared for bone marrow transplantation with total-body irradiation and cyclophosphamide should be followed closely after transplantation for the development of hypertension, proteinuria, and renal insufficiency

    1978-01-01

    Morphological changes were studied of megakaryocytes in the bone marrow and spleen of lethally irradiated mice (0.2 C/kg) after transplantation of living bone marrow cells. It was observed that functional trombopoietic megakaryocytes occur from day 15 after transplantation and that functional active megakaryocytes predominate in bone marrow and spleen from day 20. In addition, other types of cells, primarily granulocytes, were detected in some megakaryocytes. (author)

    2005-01-01

    Bone marrow transplantation has been the treatment of choice for many hematologic diseases. However, pulmonary complications, which may occur in up to 60% of the patients, are the main cause of treatment failure and may be divided in three phases according to the patient's immunity. In the first phase, up to 30 days after the procedure, there is a predominance of non-infectious complications and fungal pneumonia. Viral infections, mainly by cytomegalovirus, are common in the second phase (up to 100 days after bone marrow transplantation). Finally, in the late phase after bone marrow transplantation, non-infectious complications as bronchiolitis obliterans organizing pneumonia and graft-versus-host disease are most commonly seen. The authors present a pictorial essay of the high-resolution computed tomography findings in patients with pulmonary complications after bone marrow transplantation. (author)

    This study reviews our experience with laparoscopic cholecystectomy in the treatment of cholelithiasis in transplant patients. Demographic data, medications used, and operative and postoperative data of all transplant recipients who were subjected to laparoscopic cholecystectomy for cholelithiasis at our hospital were obtained. A total of 15 transplant patients (13 renal transplantation and 2 bone marrow transplantation) underwent laparoscopic cholecystectomy. All patients were admitted to the hospital on the day of the operation. The immunosuppressive regimen was not modified during hospitalization. Clinical presentation of cholelithiasis was biliary colicky (n=12), acute cholecystitis (n=2), and jaundice (n=1). The operation was uneventful in all patients. Postoperative complications were nausea and vomiting in 2 patients, prolonged tracheal intubation in 1, wound infection in 1 and large superficial hematoma in 1 patient. Laparoscopic cholecystectomy is associated to a low morbidity and mortality and good postoperative outcome in transplant patients with uncomplicated cholecystitis.

    Oxidative stress and reticulocyte maturity index (RMI) were studied in 27 patients who underwent bone marrow transplantation (BMT). Plasmatic lipo peroxide levels of those patients with unfavorable evolution were significantly increases on days 12-14 post-transplant (median 1,83 μM, range 0.78-5.82) compared with preconditioning levels (median 1.05 μM, range 0.36-1.84) (p<0.05). Patients with favorable evolution revealed significantly higher lipo peroxide levels during conditioning regime (median 1.42 μM, range 0.31-4.50) (p<0.05). Starting from the 3rd. post-transplant week a significant and continuous decrease was observed, with a median of 0.77 μM (range 0.21-1.48) (p<0.05) for the 3rd, and a median of 0.60 μM (range 0.11-1.48) for the 4th. week (p<0.01). A significant increase in total antioxidant activity was observed in the three patients who died up to the 35 days post-transplant. Recovery of bone marrow function was detected by RMI after a median time of 17 days (range 11-24) post-allogeneic transplantation. The threshold established for absolute neutrophil count was achieved after a median of 21 days (range 14-28) (p<0.001). An increase of plasma lipo peroxides on days 12-14 post transplant may be a predictive value of unfavourable evolution. RMI was the earlier indicator of engraftment in allogeneic BMT. (author)

    Prior to purging or cryopreservation, we concentrated 21 bone marrow (BM) harvests using a modification of the 'grancollect-protocol' of the Fresenius AS 104 cell separator with the P1-Y set. Within 40-70 min, the initial marrow volume of 1,265 ml (+/- 537 ml) was processed two to three times. A mean of 47% (+/- 21%) of the initial mononuclear cells was recovered in a mean volume of 128 ml (+36 ml). The recovery of clonogenic cells, measured by CFU-GM assays, was 68% (+/- 47%). Red blood cells in the BM concentrates were reduced to 7% (+/- 4%) of the initial number. The procedure was efficient and yielded a BM cell fraction suitable for purging, cryopreservation and transplantation. At this time, 10 of the 21 patients whose BM was processed using this technique have been transplanted. Seven of these 10 patients have been grafted using the BM alone. Three of the 10 patients showed reduced cell viability and colony growth in the thawed BM samples, and therefore obtained BM and peripheral blood-derived stem cells. All transplanted patients showed an evaluable engraftment, achieving 1,000 granulocytes per microliter of peripheral blood in a mean of 18 days.

    To retrospectively review findings of osteonecrosis of the femoral head after bone marrow transplantation. We reviewed the clinical and MR findings of osteonecrosis of the femoral head in 23 of 1112 patients who underwent marrow transplantation during a five-year follow-up period lasting from 1996 to 2000. Mean age at the time of diagnosis was 31 (range, 20-47) years, and the mean time from transplant to diagnosis was 17 months. All patients developed variable graft-versus-host disease and seventeen were treated with high-dose prednisolone and/or cysclosporin for severe acute or extensive chronic graft versus host disease. Osteonecrosis was diagnosed by magnetic resonance (MR) imaging, which allowed early detection of disease assessment of its stage. At the time of diagnosis, 15 hips were at stage I, 28 at stage II, two at stage III, and none at stage IV, according to the international ARCO classification system. Osteonecrosis of femoral diaphyses, the lower lumbar spine, or pelvic bones in the MR field was also found to have occurred in 11 patients. Initial treatment was conservative: 21 hips underwent surgery [core decompression (n=10), vascularized fibular bone graft (n=5), and joint replacement (n=6)]. In patients receiving high-dose steroids for the treatment of graft-versus-host disease, MR screening might help detect osteonecrosis at an early stage.

    We report the case of a middle-age patient presenting with severe progressive protoporphyric cholestasis. To halt further progression of liver disease, medical treatment was given aimed at different mechanisms possibly causing cholestasis in erythropoietic protoporphyria. Within eighty days, liver biochemistry completely normalized and liver histology markedly improved. Bone marrow transplantation was performed to prevent relapse of cholestatic liver disease by correcting the main site of protoporphyrin overproduction. Thirty-three months after cholestatic presentation and ten months after bone marrow transplantation, liver and porphyrin biochemistry remains normal. The patient is in excellent condition and photosensitivity is absent. The theoretical role of each treatment used to successfully reverse cholestasis and the role of bone marrow transplantation in erythropoietic protoporphyria are discussed. Medical treatment can resolve hepatic abnormalities in protoporphyric cholestasis. Bone marrow transplantation achieves phenotypic reversal and may offer protection from future protoporphyric liver disease.

  12. Post-irradiation thymocyte regeneration after bone marrow transplantation

    Boersma, W.; Betel, I.; Daculsi, R.; Westen, G. van der

    1981-01-01

    Growth kinetics of the donor-type thymus cell population after transplantation of bone marrow into irradiated syngeneic recipient mice is biphasic. During the first rapid phase of regeneration, lasting until day 19 after transplantation, the rate of development of the donor cells is independent of the number of bone marrow cells inoculated. The second slow phase is observed only when low numbers of bone marrow cells (2.5 x 10 4 ) are transplanted. The decrease in the rate of development is attributed to an efflux of donor cells from the thymus because, at the same time, the first immunologically competent cells are found in spleen. After bone marrow transplantation the regeneration of thymocyte progenitor cells in the marrow is delayed when compared to regeneration of CFUs. Therefore, regenerating marrow has a greatly reduced capacity to restore the thymus cell population. One week after transplantation of 3 x 10 6 cells, 1% of normal capacity of bone marrow is found. It is concluded that the regenerating thymus cells population after bone marrow transplantation is composed of the direct progeny of precursor cells in the inoculum. (author)

    2002-01-01

    Full Text Available Purpose: To describe a case of persistent retinopathy after bone marrow transplantation in the absence of radiation therapy. Methods: Case Report. Results: A 42 year-old man developed bilateral visual loss 15 months after receiving a bone marrow transplant for acute leukemia. The patient was treated with a high dose of cyclosporin A and oral corticosteroids. No radiation therapy was given. Late-onset, multiple, bilateral cotton-wool spots developed 15 months after the bone marrow transplantation and still persist. After three years other cotton-wool spots arose in the absence of any immunosuppressive therapy. Conclusions: Bone marrow transplantation microvasculopathy of the retina may be related to certain combinations of chemotherapy drugs or immunosuppression itself and may persist in the absence of these immunosuppressive drugs.

    Full Text Available OBJETIVO: Analisar os resultados da espirometria de pacientes submetidos a transplante de medula óssea e verificar sua importância na detecção de complicações pulmonares e sua correlação com a evolução dos pacientes. MÉTODOS:Foram analisados retrospectivamente os resultados da espirometria em 120 pacientes, maiores de doze anos, de ambos os sexos, e comparados com o tipo de transplante de medula óssea, doença de base, sorologia para citomegalovírus, fonte de células para o transplante, tabagismo, infecção pulmonar, doença pulmonar prévia, duração da doença hematológica, quimioterapia utilizada, regime de condicionamento, doença do enxerto contra o hospedeiro aguda e crônica e óbito. RESULTADOS: Dezesseis pacientes apresentaram alterações da espirometria antes do transplante, sendo 5% com obstrução pura, 5,8% com restrição pura e 2,5% com obstrução com redução da capacidade vital. Após o transplante 29 pacientes apresentaram alterações desses exames. A chance de alteração da espirometria foi maior nos pacientes com doença do enxerto contra o hospedeiro aguda (p = 0,02, idade menor que 30 anos (p = 0,02, sexo feminino (p = 0,02 e naqueles que receberam células tronco (p = 0,01. As presenças de doença pulmonar prévia e doença do enxerto contra o hospedeiro crônica associaram-se com aumento da mortalidade. Alterações prévias da espirometria não estiveram relacionadas com o óbito pós-transplante. CONCLUSÃO: As alterações detectadas na espirometria não foram capazes de predizer a ocorrência de complicações pulmonares e óbito pós-transplantes. Também não foram determinantes para a não realização do procedimento. A espirometria simples realizada na avaliação desses pacientes parece ter pouca importância prática.OBJECTIVE: To analyze the spirometry findings in patients undergoing bone marrow transplant, determining the importance of such findings in predicting postoperative pulmonary

    We analyzed the outcome of 692 patients with severe aplastic anemia (SAA) receiving transplants from HLA-matched siblings. A total of 134 grafts were peripheral blood progenitor cell (PBPC) grafts, and 558 were bone marrow (BM) grafts. Rates of hematopoietic recovery and grades 2 to 4 chronic

  16. Thyroid dysfunction among long-term survivors of bone marrow transplantation

    Sklar, C.A.; Kim, T.H.; Ramsay, N.K.

    1982-01-01

    Thyroid function studies were followed serially in 27 long-term survivors (median 33 months) of bone marrow transplantation. There were 15 men and 12 women (median age 13 1/12 years, range 11/12 to 22 6/12 years). Aplastic anemia (14 patients) and acute nonlymphocytic leukemia (eight patients) were the major reasons for bone marrow transplantation. Pretransplant conditioning consisted of single-dose irradiation combined with high-dose, short-term chemotherapy in 23 patients, while four patients received a bone marrow transplantation without any radiation therapy. Thyroid dysfunction occurred in 10 of 23 (43 percent) irradiated patients; compensated hypothyroidism (elevated thyroid-stimulating hormone levels only) developed in eight subjects, and two patients had primary thyroid failure (elevated thyroid-stimulating hormone levels and low T4 index). The abnormal thyroid studies were detected a median of 13 months after bone marrow transplantation. The four subjects who underwent transplantation without radiation therapy have remained euthyroid (median follow-up two years). The only variable that appeared to correlate with the subsequent development of impaired thyroid function was the type of graft-versus-host disease prophylaxis employed; the irradiated subjects treated with methotrexate alone had a higher incidence of thyroid dysfunction compared to those treated with methotrexate combined with antithymocyte globulin and prednisone (eight of 12 versus two of 11, p less than 0.05). The high incidence and subtle nature of impaired thyroid function following single-dose irradiation for bone marrow transplantation are discussed

  17. The costs and benefits of bone marrow transplantation.

    Beard, M E; Inder, A B; Allen, J R; Hart, D N; Heaton, D C; Spearing, R L

    1991-07-24

    The average direct costs of performing a bone marrow transplant (BMT), including the subsequent year, was found to be NZ$27,074 for 43 consecutive transplants. In 29 BMTs a full two year period of follow up was available and a quality of life analysis was carried out on these patients. It was calculated that 59 quality adjusted life years (QALYs) had been gained by the BMT procedure at the time of analysis. By combining these two analyses the cost of each QALY gained by BMT is NZ$13,272. The relatively low cost of BMT is partly due to the extremely low annual costs in second and subsequent years post BMT. In our patients this cost amounted to $195 per year. The costs and benefits of BMT compare very favourably with other complex medical procedures.

    Total-body irradiation (TBI) has an important role in patients undergoing hematopoietic cell transplantation (HCT), but is associated with significant toxicities. Targeted TBI using helical tomotherapy results in reduced doses to normal organs, which predicts for reduced toxicities compared with standard TBI. Thirteen patients with multiple myeloma were treated in an autologous tandem transplantation Phase I trial with high-dose melphalan, followed 6 weeks later by total-marrow irradiation (TMI) to skeletal bone. Dose levels were 10, 12, 14, and 16 Gy at 2 Gy daily/twice daily. In a separate allogeneic HCT trial, 8 patients (5 with acute myelogenous leukemia, 1 with acute lymphoblastic leukemia, 1 with non-Hodgkin's lymphoma, and 1 with multiple myeloma) were treated with TMI plus total lymphoid irradiation plus splenic radiotherapy to 12 Gy (1.5 Gy twice daily) combined with fludarabine/melphalan. For the 13 patients in the tandem autologous HCT trial, median age was 54 years (range, 42-66 years). Median organ doses were 15-65% that of the gross target volume dose. Primarily Grades 1-2 acute toxicities were observed. Six patients reported no vomiting; 9 patients, no mucositis; 6 patients, no fatigue; and 8 patients, no diarrhea. For the 8 patients in the allogeneic HCT trial, median age was 52 years (range, 24-61 years). Grades 2-3 nausea, vomiting, mucositis, and diarrhea were observed. In both trials, no Grade 4 nonhematologic toxicity was observed, and all patients underwent successful engraftment. This study shows that TMI using helical tomotherapy is clinically feasible. The reduced acute toxicities observed compare favorably with those seen with standard TBI. Initial results are encouraging and warrant further evaluation as a method to dose escalate with acceptable toxicity or to offer TBI-containing regimens to patients unable to tolerate standard approaches.

    1988-01-01

    In a retrospective study chest radiographs of 87 bone marrow transplant recipients were analysed. 36 patients had pulmonary complications with lung opacifications. Interstitial changes were more frequent than air-space pneumonias. The latter were caused by bacteria and fungi only. The most common cause of pulmonary complications was cytomegalovirus pneumonia. It was characterised uniformly by a bilateral diffuse interstitial pattern. Idiopathic interstitial pneumonias were indistinguishable from CMV infection. Pneumonias caused by Epstein-Barr virus and protozoa, diffuse radiation pneumonitis and leukaemic infiltrates were rare and also associated with interstitial changes.

    This report retrospectively analyzed the outcome of 91 patients aged 60 years or older with refractory/relapsed (R/R) classical Hodgkin's lymphoma (cHL) who underwent autologous stem cell transplantation (ASCT) between 1992 and 2013 and were reported to the French Society of Bone Marrow Transplantation and Cell Therapies registry. The median age at transplant was 63 years. The majority of patients exhibited disease chemosensitivity to salvage treatment (57 complete responses, 30 partial responses, 1 progressive disease and 3 unknown). The most frequent conditioning regimen consisted of BCNU, cytarabine, etoposide, melphalan (BEAM) chemotherapy (93%). With a median follow-up of 54 months, 5-year estimates of overall survival (OS) and progression free survival (PFS) for the entire group were 67 and 54%, respectively. Despite the missing data, in univariate analysis, the number of salvage chemotherapy lines (1-2 versus ⩾3) significantly influenced the OS, unlike the other prognostic factors (stage III-IV at relapse, disease status before ASCT and negative positron emission tomography (PET) scan) encountered in younger patients. In spite of its limitations, this retrospective study with a long-term follow-up suggests that ASCT is a valid treatment option for chemosensitive R/R cHL in selected elderly patients, with an acceptable rate of toxicity.

  3. Risk factors for treatment failure after allogeneic transplantation of patients with CLL: a report from the European Society for Blood and Marrow Transplantation.

    2017-04-01

    For young patients with high-risk CLL, BTK-/PI3K-inhibitors or allogeneic stem cell transplantation (alloHCT) are considered. Patients with a low risk of non-relapse mortality (NRM) but a high risk of failure of targeted therapy may benefit most from alloHCT. We performed Cox regression analyses to identify risk factors for 2-year NRM and 5-year event-free survival (using EFS as a surrogate for long-term disease control) in a large, updated EBMT registry cohort (n= 694). For the whole cohort, 2-year NRM was 28% and 5-year EFS 37%. Higher age, lower performance status, unrelated donor type and unfavorable sex-mismatch had a significant adverse impact on 2-year NRM. Two-year NRM was calculated for good- and poor-risk reference patients. Predicted 2-year-NRM was 11 and 12% for male and female good-risk patients compared with 42 and 33% for male and female poor-risk patients. For 5-year EFS, age, performance status, prior autologous HCT, remission status and sex-mismatch had a significant impact, whereas del(17p) did not. The model-based prediction of 5-year EFS was 55% and 64%, respectively, for male and female good-risk patients. Good-risk transplant candidates with high-risk CLL and limited prognosis either on or after failure of targeted therapy should still be considered for alloHCT.

  4. High-dose therapy and autologous bone marrow transplantation for Hodgkin's disease patients with relapses potentially treatable by radical radiation therapy

    Pezner, Richard D.; Nademanee, Auayporn; Forman, Stephen J.

    1995-01-01

    Purpose: A retrospective review evaluated the results of autologous bone marrow transplantation (A-BMT) for patients with relapsed Hodgkin's disease (HD) who were potentially treatable by radical radiation therapy (RRT). Methods and Materials: Evaluated patient cases met the following criteria: initial treatment with chemotherapy (with or without involved field radiation therapy 20 Gy to spinal cord); HD at time of salvage therapy limited to lymph nodes, Waldeyer's ring, liver, spleen, direct extension sites, and/or one lung. Results: There were 23 A-BMT patients treated between 1986 and 1991 who fulfilled the criteria. Three (13%) patients died from treatment-related complications and eight (35%) developed nonfatal Grade 3-4 complications. The 3-year actuarial disease-free survival rate was 61%. The 3-year disease-free survival rate was 55% for the nine patients with at least one prior disease-free interval (DFI) > 12 months, 67% for nine patients with DFI 0.10). These results are comparable to retrospective studies of RRT results in selected relapsed HD patients. Conclusions: Long-term disease-free survival is frequently possible with either A-BMT or RRT appropriately selected relapsed HD patients. In considering treatment options, important prognostic factors include initial stage of disease, number of prior relapses, DFI, and extent of relapsed disease

  5. Demonstration of clonable alloreactive host T cells in a primate model for bone marrow transplantation

    Reisner, Y.; Ben-Bassat, I.; Douer, D.; Kaploon, A.; Schwartz, E.; Ramot, B.

    1986-01-01

    The phenomenon of marrow rejection following supralethal radiochemotherapy was explained in the past mainly by non-T-cell mechanisms known to be resistant to high-dose irradiation. In the present study a low but significant number of radiochemoresistant-clonable T cells was found in the peripheral blood and spleen of Rhesus monkeys following the cytoreductive protocol used for treatment of leukemia patients prior to bone marrow transplantation. More than 95% of the clonable cells are concentrated in the spleen 5 days after transplant. The cells possess immune memory as demonstrated by the generation of alloreactive-specific cytotoxicity. The present findings suggest that host-versus-graft activity may be mediated by alloreactive T cells. It is hoped that elimination of such cells prior to bone marrow transplantation will increase the engraftment rate of HLA-nonidentical marrow in leukemia patients

  6. MRI of intracranial toxoplasmosis after bone marrow transplantation

    Dietrich, U.; Doerfler, A.; Forsting, M.; Maschke, M.; Prumbaum, M.

    2000-01-01

    Toxoplasma encephalitis was confirmed by biopsy in three patients with bone marrow (BMT) or peripheral blood stem-cell transplantation (PBSCT). All had MRI before antimicrobial therapy. The intensity of contrast enhancement was very variable. One patient had one large, moderately enhancing cerebral lesion and several smaller almost nonenhancing lesions. The second had small nodular and haemorrhagic lesions without any enhancement. The third had late cerebral toxoplasmosis and showed multiple lesions with marked contrast enhancement. The moderate or absent contrast enhancement in the two patients in the early phase of cerebral toxoplasmosis may be related to a poor immunological response, with a low white blood cell count in at least one patient. Both received higher doses of prednisone than the patient with late infection, leading to a reduced inflammatory response. In patients with a low leukocyte count and/or high doses of immunosuppressive therapy, typical contrast enhancement may be absent. (orig.)

    1997-01-01

    Purpose: To evaluate the efficiency of Helium-Neon (He-Ne) laser in the prevention of oral mucositis induced by high dose chemoradiotherapy before autologous bone marrow transplantation (BMT). Methods and Materials: Between 1993 and 1995, 30 consecutive patients receiving an autologous peripheral stem-cell or bone marrow transplant (BMT) after high dose chemoradiotherapy were randomized to possibly receive prophylactic laser to the oral mucosa after giving informed consent. Chemotherapy consisted of cyclophosphamide, 60 mg/kg intravenously (IV) on day (d)-5 and d-4 in 27 cases, or melphalan 140 mg/kg IV on d-4 in three cases. Total body irradiation (TBI) consisted of 12 Gy midplane dose in six fractions (4 Gy/day for three days). He-Ne laser (632.8 nm wavelength, power 60 mW) applications were performed daily from d-5 to d-1 on five anatomic sites of the oral mucosa. Oral examination was performed daily from d0 to d + 20. Mucositis was scored according to an oral exam guide with a 16 item scale of which four were assessed by the patients themselves. Mean daily self assessment scores for oral pain, ability to swallow and oral dryness were measured. A daily mucositis index (DMI) and a cumulative oral mucositis score (COMS) were established. Requirement for narcotics and parenteral nutrition was recorded. Results: The COMS was significantly reduced among laser treated (L+) patients (p = 0.04). The improvement of DMI in L+ patients was also statistically significant (p < 0.05) from d + 2 to d + 7. Occurrence and duration of grade III oral mucositis were reduced in L+ patients (p = 0.01). Laser applications reduced oral pain as assessed by patients (p = 0.05) and L+ patients required less morphine (p = 0.05). Xerostomia and ability to swallow were improved among the L+ patients (p = 0.005 and p = 0.01, respectively). Requirement for parenteral nutrition was not reduced (p = NS). Conclusion: Helium-Neon laser treatment was well tolerated, feasible in all cases, and

    Based on the cytoreductive regimen reported by O'Reilly et al, we transplanted to four patients with hematological malignancy the bone marrow cells harvested from their HLA identical siblings. In our method, they were pretreated with hyperfractionated total body irradiation (120R x 11 times) and high dose of cyclophosphamide prior to transplantation. Case 1: 19 year-old, female, ALL. She had a temporal GVHD (Grade I) on day 23, and suffered from interstitial pneumonia (IP) on day 72 that responded well to the steroid therapy. She is now healthy (day 717). Case 2: 15 year-old, female, ALL. She had a mild GVHD on day 20 and IP on day 175 that recovered shortly after treated with steroid. She had an acute nephritis temporarily on day 410, as well. She is now healthy (day 668). Case 3: 39 year-old, female, AML. She suffered from a GVHD (Grade IV) with severe skin eruption, diarrhea and jaundice, which started on day 15.

    Sickle cell anemia (SCA) and β -thalassemia major are well-recognized beta-globin gene disorders of red blood cells associated to mortality and morbidity included bone morbidities due to ineffective erythropoiesis and bone marrow expansion, which affect every part of the skeleton. While there are an abundance of described disease manifestations of the head and neck, the manner of paranasal sinuses involvement and its relations to β-thalassemia and SCA process was not studied yet. Therefore, the aim of this study was to investigate a possible increased risk of rhinosinusitis and the real pathogenetic mechanism of it, comparing these two hematological diseases using msCT, gold standard for paranasal sinuses evaluation. A retrospective analysis of 90 patients affected by β-thalassemia major or SCA (respectively 59 and 31) underwent allogeneic bone marrow transplantation (BMT), and 44 control subjects was performed. Both patient categories and control group have been subjected to hematological and radiological evaluation using 64-multidetector-row CT scanner without contrast injection. Statistical analysis reveals that patients of the two study groups exhibit a significantly increased risk of sinusitis in comparison with the normal controls (RR: 3.55 for β-thalassemic pediatric subjects; RR: 3.35 for SCA pediatric subjects). A significant difference (p < 0,5) was found between the β -thalassemic patients on the one side, and SCA and control group on the other side, with regard to the evaluation of the typical anatomic alteration of maxillary sinus: β-thalassemic children had significant increase in the bone thickness of anterior and lateral sinus walls and significant reduction in volume and density compared to SCA patients and control group, with normal conditions of these parameters. In these hematological patients, there is an increased incidence of sinonasal infections due their therapy-induced immunosuppression post transplantation. In

    Reversible posterior leucoencephalopathy syndrome (RPLS) has previously been described in patients who have renal insufficiency, eclampsia, hypertensive encephalopathy and patients receiving immunosuppressive therapy. The mechanism by which immunosuppressive agents can cause this syndrome is not clear, but it is probably related with cytotoxic effects of these agents on the vascular endothelium. We report eight patients who received cyclosporine A (CSA) after allogeneic bone marrow transplantation or as treatment for severe aplastic anemia (SSA) who developed posterior leucoencephalopathy. The most common signs and symptoms were seizures and headache. Neurological dysfunction occurred preceded by or concomitant with high blood pressure and some degree of acute renal failure in six patients. Computerized tomography studies showed low-density white matter lesions involving the posterior areas of cerebral hemispheres. Symptoms and neuroimaging abnormalities were reversible and improvement occurred in all patients when given lower doses of CSA or when the drug was withdrawn. RPLS may be considered an expression of CSA neurotoxicity.

  11. Bone marrow transplantation and other treatment after radiation injury

    Balner, H.

    1977-01-01

    This review deals mainly with current concepts about bone marrow transplantation as therapy for serious radiation injury. Such injury can be classified according to the following broadly defined dose ranges: (1) the supralethal range, leading mainly to the cerebral and intestinal syndromes; (2) the potentially lethal or therapeutic range which causes the bone marrow syndrome, and (3) the sublethal range which rarely leads to injury requiring therapy. The bone marrow syndrome of man and animals is discussed in detail. The optimal therapy for this syndrome is bone marrow transplantation in conjunction with conventional supportive treatment. The principal complications of such therapy are Graft versus Host Disease and a slow recovery of the recipient's immune system. Concerted research activities in a number of institutions have led to considerable progress in the field of bone marrow transplantation. Improved donor selection, new techniques for stem-cell separation and preservation, as well as effective barrier-nursing and antibiotic decontamination, have made bone marrow transplantation an accepted therapy for marrow depression, including the aplasia caused by excessive exposure to radiation. The review also contains a number of guidelines for the handling of serious radiation accidents. (Auth.)

  12. Busulfan, cyclophosphamide and fractionated total body irradiation as a conditioning regimen for allogeneic bone marrow transplantation in patients with non-lymphocytic hematopoietic malignancies

    Watanabe, Hiroshi

    1996-01-01

    Allogeneic bone marrow transplantation (BMT) with the conditioning regimen of 8 mg/kg of busulfan (BUS), 120 mg/kg of cyclophosphamide (CPM) and 10 Gy of total body irradiation (TBI) was evaluated in the patients with non-lymphocytic hematopoietic malignancies. The disease distribution of the 22 patients was as follows; 14 in the standard risk group (SRG), 8 in the high risk group (HRG). SRG included the patients with acute myeloid leukemia (AML) in the first complete remission, chronic myelogenous leukemia (CML) in chronic phase and myelodysplastic syndrome with refractory anemia, while HRG included the patients with refractory AML and CML in blastic phase. The median age of patients was 33 years old (y.o.), and the median observation period was 34.5 months No relapse occurred, but 8 patients (36%) died of various complications. Ail the patients who died of interstitial pneumonitis (4 cases) were 40 y.o. and more. Acute graft-versus-host disease (GvHD) and chronic GvHD were clinically controllable. The probability of disease-free survival rate at 5 years (5y-DFS) was 50.0% in overall patients. The 5y-DFS was 57.1% in HRG (7 cases), while 54.3% in SRG (13 cases) donated from the HLA identical siblings (20 cases). In these 13 patients in SRG, the 5y-DFS was 100% in patients under 40 y.o. (6 cases), while the probability of disease-free survival rate at 3 years was 68.6% and the 5y-DFS was 0% in patients over 40 y.o. (7 cases). Our data indicate that the conditioning regimen combining BUS, CPM and TBI for allogeneic BMT is promising for the treatment of the patients of HRG and the patients under 40 y.o. in SRG. (author)

    Vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC) result from genetic and environmental factors. We present patients who had no history of atopic disorders before bone marrow transplantation (BMT) and who seem to have acquired VKC or AKC from their donors, who had atopic disorders. Observational case series. The patients in this study were part of a cohort of patients who had undergone allogeneic hemapoietic stem cell transplantation (HSCT) from January 1997 through December 2007. Of 621 HSCT recipients, four recipients who were free of allergic disorders acquired VKC or AKC from their afflicted donors after HSCT. Each patient underwent complete ophthalmologic examination, determination of the total serum immunoglobulin (Ig) E, and conjunctival scrapings. Four (0.64%) of 621 patients who had undergone HSCT acquired VKC or AKC after BMT. The donors had VKC or atopic dermatitis. In addition, in two of these four patients, asthma developed. One patient had elevated total serum IgE. Conjunctival scrapings of all four patients revealed the presence of eosinophils. One patient had concurrent graft-versus-host disease. VKC and AKC are systemic allergic disorders characterized by local ocular manifestations. This report suggests the possibility of the acquisition of VKC or AKC after BMT by adoptive transfer.

    Full text: The total body irradiation (TBI) combined with intensive chemotherapy plays an important role in the preparation of patients for bone marrow transplantation (BMT). The first autologous BMT in Bulgaria was performed in 1997 in the Specialized Pediatric Hospital for Active Treatment (SPHAT) of oncohematological diseases. The first TBI, followed by allogeneic BMT, was carried out in 2002 in the 'Queen Giovanna' University Hospital, after which its routine application as a basic form of large field radiotherapy and a main stage of the conditioning regimen for BMT was started. Fourteen allogeneic BMTs including TBI as a basic conditioning regimen have been performed till May 2006. The objective of the present report is to present the first clinical observations in the Bulgarian oncological practice on 'mini' TBI followed by allogeneic blood stem cell transplantation. During the period October 2005 - May 2006, 'mini' TBI followed by allogeneic BMT was carried out for two patients of the age 43 and 50 years. The diagnosis of both patients was acute non-lymphoblastic leukemia, in the remission stage, after one relapse, respectively. Intensive preceding chemotherapy was applied for both patients. A conditioning regimen was applied including the fludarabine purine analogue (3 x 30 mg/m 2 ) and 200 cGy TBI. It was followed by transplantation of allogeneic cell concentrate containing 2.5 x10 6 /kg CD34+ and 4.0 x10 6 /kg CD34+ blood stem cells of partially compatible family donors (a sister and a son), which were tolerable for the patients without complications. Cyclosporine and mycophelonate mofetile were applied as post-transplantation treatment. Active antibiotic, antiviral, symptomatic and substituting therapy, as well as GvHD prophylaxis was applied for both patients. Good clinical tolerance was recorded for the applied low dose conditioning regimen. The patients were discharged within 30 days in good general condition and stable draft action, with

    The liver is the current site of choice for pancreatic islet transplantation, even though it is far from being ideal. We recently have shown in mice that the bone marrow (BM) may be a valid alternative to the liver, and here we report a pilot study to test feasibility and safety of BM as a site for islet transplantation in humans. Four patients who developed diabetes after total pancreatectomy were candidates for the autologous transplantation of pancreatic islet. Because the patients had contraindications for intraportal infusion, islets were infused in the BM. In all recipients, islets engrafted successfully as shown by measurable posttransplantation C-peptide levels and histopathological evidence of insulin-producing cells or molecular markers of endocrine tissue in BM biopsy samples analyzed during follow-up. Thus far, we have recorded no adverse events related to the infusion procedure or the presence of islets in the BM. Islet function was sustained for the maximum follow-up of 944 days. The encouraging results of this pilot study provide new perspectives in identifying alternative sites for islet infusion in patients with type 1 diabetes. Moreover, this is the first unequivocal example of successful engraftment of endocrine tissue in the BM in humans. PMID:23733196

  17. Bone marrow transplantation for acute myelogenous leukemia: factors associated with early mortality

    1983-01-01

    Comprehensive data were reported to the International Bone Marrow Transplant Registry, Milwaukee, regarding 156 patients with acute myelogenous leukemia who were treated with allogeneic bone marrow transplantation between 1978 and 1980. The minimum observation period was 15 months after transplant and most deaths occurred within the first six months. Prognostic factors were evaluated for associations with early mortality or life-threatening complications. Most early deaths were due to infections, interstitial pneumonitis, and graft-v-host disease (GVHD). Multivariate analyses disclosed five factors with significant associations with early death or a major cause of early death: (1) disease status; (2) dose-rate of irradiation; (3) drug used to prevent GVHD; (4) severity of GVHD; and (5) dose of marrow cells.It is emphasized that several of the important prognostic factors are within the control of the referring physician or the transplant team

    1981-01-01

    Twenty-four patients with aplastic anemia or acute leukemia were treated by marrow grafts from HLA-identical donors after conditioning with high doses of cyclophosphamide and/or today body irradiation. They were studied between 4 and 63 mo (median 14.2) after transplantation. Seventeen patients had chronic graft-versus-host disease (C-GVHD) and 7 were healthy. They were studied for defects in their T- and B-cell function using and indirect hemolytic plaque assay for Ig production after 6 days of culture in the presence of pokeweek mitogen. T or B cells from the patients with or without C-GVHD were cocultured with T or B cells from their HLA-identical marrow donors or unrelated normal controls. Intrinsic B-cell defects, lack of helper T-cell activity, and suppressor T-cell activity were more frequently found in patients with C-GVHD than in healthy patients. Fifteen of the 17 patients with C-GVHD showed on or more defects in their T-and B-cell function compared to only 3 of the 7 patients without C-GVHD. None of the healthy controls, including the marrow donors, showed defects in their T- and B-cell functions. These in vitro findings may be helpful in assessing the process of immune reconstitution and the immunologic aberration found after human marrow transplantation

    The influence of total-body irradiation (TBI) and autologous or allogeneic bone marrow transplantation on serum immunoglobulin subclasses was determined in a dog model. Only IgG1 levels decreased after low-dose (+/- 4.5 Gy) TBI, but levels of all immunoglobulin classes fell after high-dose TBI (8.5 GyX1 or 2X6.0 Gy). After autologous bone marrow transplantation IgM levels were the first and IgE levels were the last to return to normal. After successful allogeneic bone marrow transplantation prolonged low IgM and IgE levels were found but IgA levels increased rapidly to over 150% of pretreatment values. A comparison of dogs with or without clinical signs or graft-versus-host disease (GVHD), revealed no differences in IgM levels. Dogs with GVHD had higher IgA but lower IgE levels. Dogs that rejected their allogeneic bone marrow cells showed significant early rises in IgE and IgA levels in comparison with dogs with GVHD. These results differ from the observations made on Ig levels in human bone marrow transplant patients. No significant differences in phytohemagglutinin stimulation tests were found between dogs with or without GVHD or dogs receiving an autologous transplant for the first four months after TBI and transplantation. An early primary or secondary involvement of humoral immunity in GVHD and graft rejection in dogs is postulated

  20. CT analysis of lung density changes in patients undergoing total body irradiation prior to bone marrow transplantation

    Lee, J.Y.; Shank, B.; Bonfiglio, P.; Reid, A.

    1984-01-01

    Sequential changes in lung density measured by CT are potentially sensitive and convenient monitors of lung abnormalities following total body irradiation (TBI). Methods have been developed to compare pre- and post-TBI CT of lung. The average local features of a cross-sectional lung slice are extracted from three peripheral regions of interest in the anterior, posterior, and lateral portions of the CT image. Also, density profiles across a specific region may be obtained. These may be compared first for verification of patient position and breathing status and then for changes between pre- and post-TBI. These may also be compared with radiation dose profiles through the lung. A preliminary study on 21 leukemia patients undergoing total body irradiation indicates the following: (a) Density gradients of patients' lungs in the antero-posterior direction show a marked heterogeneity before and after transplantation compared with normal lungs. The patients with departures from normal density gradients pre-TBI correlate with later pulmonary complications. (b) Measurements of average peripheral lung densities have demonstrated that the average lung density in the younger age group is substantially higher: pre-TBI, the average CT number (1,000 scale) is -638 +/- 39 Hounsfield unit (HU) for 0-10 years old and -739 +/- 53 HU for 21-40 years old. (c) Density profiles showed no post-TBI regional changes in lung density corresponding to the dose profile across the lung, so no differentiation of a radiation-specific effect has yet been possible. Computed tomographic density profiles in the antero-posterior direction are successfully used to verify positioning of the CT slice and the breathing level of the lung

    The authors present short and long-term results of allogeneic bone marrow transplantation after hyper-fractionated total body irradiation and high dose cyclophosphamide in ten patients treated for leukaemia during th period 1985-89. Three patients died from complications connected to the transplantation, while seven are living free from leukaemia 18 to 59 months after transplantation. Two patients need treatment for chronic graft versus host disease. Allogeneic bone marrow transplantation is expensive and risky. Close cooperation between clinicians and laboratory specialists is essential. The treatment increases long term survival and probably cures certain patients with leukaemia. Some of the patients will need treatment for chronic graft versus host disease and other late sequelae. 19 refs., 2 tabs

    Fourteen patients with chronic granulocytic leukemia received bone marrow grafts from HLA identical siblings. Ten patients were in blast crisis prior to grafting, three were in an accelerated phase of their disease, and one was aplastic secondary to chemotherapy. Prior to transplant all patients were conditioned with chemotherapy including cyclophosphamide plus 1,000 rad of total body irradiation. Ten patients achieved engraftment while four died 1 to 26 days after marrow infusion without functioning grafts. Two patients reveived a second infusion of donor marrow because of delayed engraftment. Neither marrow cell dose nor presence of myelofibrosis correlated with succesful engraftment. Three out of ten engrafted patients developed graft-versus-host disease. Interstitial pneumonia occurred in seven patients. The immediate cause of death was bacterial septicemia in six patients. All evidence of leukemia disappeared in nine out of ten evaluable patients. The median survival was 43 days. One patient had a complete remission of 16 months duration.

    The actual heparin concentration of harvested allogeneic bone marrow varies among harvest centers. We monitor the activated partial thromboplastin time (APTT) of the patient during bone marrow infusion and administer prophylactic protamine according to the APTT. We retrospectively reviewed the charts of consecutive patients who underwent bone marrow transplantation without bone marrow processing at our center between April 2007 and March 2016 (n = 94). APTT was monitored during marrow transfusion in 52 patients. We analyzed the relationship between the APTT ratio and several parameters related to heparin administration. As a result, the weight-based heparin administration rate (U/kg/hour) seemed to be more closely related to the APTT ratio (r = .38, P = .005) than to the total amount of heparin. There was no significant correlation between the APTT ratio and renal or liver function. Bleeding complications during and early after infusion were seen in 3 of 52 patients, and included intracranial, nasal, and punctured-skin bleeding. The APTT ratio during transfusion was over 5.88 in the former 2 patients and 2.14 in the latter. All of these patients recovered without sequelae. In conclusion, slow bone marrow infusion is recommended to decrease the weight-based heparin administration rate when the heparin concentration per patient body weight is high.

    We report three patients who developed severe supraglottic airway obstruction due to Epstein-Barr virus lymphoproliferative disease following allogeneic bone marrow transplantation. In addition to enlarged pharyngeal lymphoid tissue seen in all three patients, two had supraglottic airway narrowing and two developed pulmonary lymphoproliferative disease. They were treated with unmanipulated T cells or EBV-specific cytotoxic T lymphocytes. Life-threatening upper airway obstruction is a radiologically detectable complication of allogeneic bone marrow transplantation in children. (orig.) With 3 figs., 1 tab., 12 refs.

  7. Post-irradiation thymocyte regeneration after bone marrow transplantation

    Boersma, W.J.A.

    1981-01-01

    Bone marrow cells were separated according to buoyant density, velocity sedimentation and cell surface charge. Fractionated (C3H x AKR)F 1 bone marrow cells were transplanted into lethally-irradiated C3H recipients. In all fractions, the CFUs content and the capacity to restore the thymus cell population were determined. For all the physical parameters tested, thymocyte progenitor cells show the same distribution as CFUs. The relationship between number of thymocyte progenitor cells and number of CFUs is dependent on density. Bone marrow progenitors of PHA responsive cells are of low buoyant density and show a distribution which resembles the distribution of the progenitors of Thy 1 positive cells. After transplantation of large numbers of bone marrow cells into irradiated mice, no significant change in the CFUs content of the thymus was observed. (author)

  8. Analyzing the cellular contribution of bone marrow to fracture healing using bone marrow transplantation in mice

    Colnot, C.; Huang, S.; Helms, J.

    2006-01-01

    The bone marrow is believed to play important roles during fracture healing such as providing progenitor cells for inflammation, matrix remodeling, and cartilage and bone formation. Given the complex nature of bone repair, it remains difficult to distinguish the contributions of various cell types. Here we describe a mouse model based on bone marrow transplantation and genetic labeling to track cells originating from bone marrow during fracture healing. Following lethal irradiation and engraftment of bone marrow expressing the LacZ transgene constitutively, wild type mice underwent tibial fracture. Donor bone marrow-derived cells, which originated from the hematopoietic compartment, did not participate in the chondrogenic and osteogenic lineages during fracture healing. Instead, the donor bone marrow contributed to inflammatory and bone resorbing cells. This model can be exploited in the future to investigate the role of inflammation and matrix remodeling during bone repair, independent from osteogenesis and chondrogenesis

Matrix metalloproteinase-9 (MMP-9, regulated by tissue inhibitor of metalloproteinase-9 (TIMP-1 and the extracellular matrix metalloproteinase inducer (EMMPRIN, contributes to plaque instability. Autologous stem cells from bone marrow (mBMC treatment are suggested to reduce myocardial damage; however, limited data exists on the influence of mBMC on MMPs. Aim. We investigated the influence of mBMC on circulating levels of MMP-9, TIMP-1, and EMMPRIN at different time points in patients included in the randomized Autologous Stem-Cell Transplantation in Acute Myocardial Infarction (ASTAMI trial (n=100. Gene expression analyses were additionally performed. Results. After 2-3 weeks we observed a more pronounced increase in MMP-9 levels in the mBMC group, compared to controls (P=0.030, whereas EMMPRIN levels were reduced from baseline to 2-3 weeks and 3 months in both groups (P<0.0001. Gene expression of both MMP-9 and EMMPRIN was reduced from baseline to 3 months. MMP-9 and EMMPRIN were significantly correlated to myocardial injury (CK: P=0.005 and P<0.001, resp. and infarct size (SPECT: P=0.018 and P=0.008, resp.. Conclusion. The results indicate that the regulation of metalloproteinases is important during AMI, however, limited influenced by mBMC.

  10. Bone marrow transplantation for correction of enzyme deficiency disease

    Hong, C.; Sutherland, D.E.R.; Matas, A.J.; Najarian, J.S.

    1979-01-01

    Mutant acatalasemic mice provide a prototype of congenital enzyme deficiency disease. Normal blood catalase levels were achieved permanently in congenitally acatalasemic mice by transplantation of bone marrow cells from congeneic normal catalasemic mice using relatively small numbers of cells following whole body irradiation. The increase in blood catalase activity was physiologically effective as demonstrated by the protection of the previously acatalasemic mice against the otherwise lethal effects of hydrogen peroxide injections. Bone marrow transplantation has the potential to provide a continuous source of some enzymes and may be applicable as treatment for certain congenital enzyme deficiency diseases

    We performed a pilot study to test the effectiveness of allogeneic bone marrow transplantation in the treatment of chronic myelogenous leukemia. Five patients in the advanced stages of chronic myelogenous leukemia (four in blast crisis, one in accelerated phase) with abnormal chromosomes underwent matched-sibling allogeneic bone marrow transplantation after preparation with busulfan, vincristine, cyclophosphamide, and fractionated total body irradiation. Engraftment and conversion to normal chromosome patterns after transplantation occurred in all five patients. None of the patients reverted to an abnormal chromosome pattern or demonstrated clinical or hematologic evidence of recurrent disease during the course of this study; however, longest survival from transplant was 248 days. Allogeneic bone marrow transplantation can eradicate the abnormal clone even in far advanced chronic myelogenous leukemia and can provide normal hematopoiesis. We suggest that clinical complications of chemotherapeutic toxicity and infection were responsible for the short survival in this group of patients, and that these complications could be decreased by performing transplantation in the chronic phase or early accelerated phase of the disease

    Background In 2014, a screening tool was implemented at Medical University of South Carolina (MUSC) Health to identify patients who are at risk for medication-related events. Patients are classified as high-risk if they meet one of the following criteria: receiving anticoagulation therapy, taking more than 10 scheduled medications upon admission, or readmission within the past 30 days. The goal of this study was to determine risk criteria specific to the malignant hematology (MH) and bone marrow transplant (BMT) patients. Methods A retrospective chart review of 114 patients admitted and discharged from the MH/BMT services between 1 September 2015 and 31 October 2015 was performed. A pharmacist-conducted medication history was completed and documented, and all interventions at admission and throughout hospitalization were categorized by severity and by value of service. The primary objective was to evaluate if patients in the MH/BMT services have more medication-related interventions documented upon admission compared with patients who are not screened as high risk. The secondary objectives were to evaluate the different types and severities of interventions made by pharmacists during the entire hospital stay, and to determine if there are certain characteristics that can help identify hematology/oncology high-risk patients. Results More interventions documented upon admission in the high-risk group as a whole when compared with the not high-risk group (73 vs. 31), but when normalized per patients in each group, there was an equal number of interventions (1.0). The most common interventions were to modify regimen (36%) and discontinue therapy (16%). The patient characteristics associated with high-risk included neutropenia, lower average platelet counts on admission, and longer length of stay. Conclusion The screening tool does not further differentiate an already complex MH/BMT patient population. Pharmacists may be more useful at capturing errors or changes during

    Yeager, A M; Kanof, M E; Lake, A M; Kramer, S S; Jones, B; Saral, R; Santos, G W

    1987-01-01

    Four children, ages 3 to 8 years, developed pneumatosis intestinalis (PI) after allogeneic bone marrow transplantation (BMT) for acute leukemia or severe aplastic anemia. PI was detected at a median of 48 days (range, 10-63 days) after BMT and was associated with abdominal symptoms and clinical signs. All patients had severe systemic and/or highgrade cutaneous acute graft-versus-host disease (AGVHD) at some time after BMT and were receiving corticosteroids at the time of development of PI; however, PI was associated with concomitant severe AGVHD in only one patient. One patient with PI had Hafnia alvei bacteremia and another patient had gastroenteritis due to rotavirus and adenovirus. All patients were treated with supportive care and systemic broad-spectrum antibiotics, and PI resolved 2-16 days after onset. Two patients died with BMT-associated complications unrelated to PI. Multiple factors contribute to the development of PI after BMT, and the prognosis for recovery from PI is good with medical management alone. Overall survival in these patients is dependent on the frequency and severity of other conditions, such as AGVHD and opportunistic infections, after BMT.

    Full Text Available Os cuidados gerais relativos ao paciente submetido ao transplante de medula óssea (TMO incluem avaliações odontológicas rotineiras, as quais devem estar inseridas em um contexto multiprofissional. A cavidade oral constitui um sítio propício a infecções com grande potencial de desenvolvimento de bacteremia, sendo que lesões infecciosas devem ser previamente tratadas e controladas pelo cirurgião-dentista. O objetivo desta revisão é discutir questões em destaque na literatura nacional e internacional referentes aos quadros inflamatórios e infecciosos orais de importância para o paciente transplantado de medula óssea, tanto os predisponentes a complicações durante o transplante, quanto os que ocorrem durante e após a terapia mielossupressora. Destaca-se na literatura a doença periodontal avançada, a qual constitui um quadro infeccioso crônico que deve ser evitado ou controlado durante o TMO, principalmente devido à presença de S. viridans. Os fatores de risco para mucosite oral (OM, doença do enxerto contra o hospedeiro (DECH e xerostomia ainda não estão definidos, principalmente para OM e DECH. São citadas na literatura alternativas promissoras de tratamento para OM, tais como crioterapia, administração de fatores de crescimento e laserterapia. O risco aumentado de cárie é controverso e, dentre as lesões fúngicas e virais, destacam-se as infecções orais e de orofaringe por Candida e pela família de herpesvírus, de importância clínica considerável. Em pacientes pediátricos são relevantes as alterações craniofaciais e dentárias, decorrentes principalmente da radioterapia.General care in bone marrow transplant (BMT patients includes routine dental evaluations, which must be included in a multi-professional context.

    Over the past quarter century, tremendous technological advances have been made in bone marrow and solid organ transplantation. Despite these advances, an enduring problem for the transplant recipient is infection. As immunosuppressive regimens have become more systematic, it is apparent that different pathogens affect the transplant recipient at different time points in the posttransplantation course, since they are influenced by multiple intrinsic and extrinsic factors. An understanding of ...

    Full Text Available Cell therapy is being widely explored in the management of stroke and has demonstrated great potential. It has been shown to assist in the remodeling of the central nervous system by inducing neurorestorative effect through the process of angiogenesis, neurogenesis, and reduction of glial scar formation. In this study, the effect of intrathecal administration of autologous bone marrow mononuclear cells (BMMNCs is analyzed on the recovery process of patients with chronic stroke. 24 patients diagnosed with chronic stroke were administered cell therapy, followed by multidisciplinary neurorehabilitation. They were assessed on functional independence measure (FIM objectively, along with assessment of standing and walking balance, ambulation, and hand functions. Out of 24 patients, 12 improved in ambulation, 10 in hand functions, 6 in standing balance, and 9 in walking balance. Further factor analysis was done. Patients of the younger groups showed higher percentage of improvement in all the areas. Patients who underwent cell therapy within 2 years after the stroke showed better changes. Ischemic type of stroke had better recovery than the hemorrhagic stroke. This study demonstrates the potential of autologous BMMNCs intrathecal transplantation in improving the prognosis of functional recovery in chronic stage of stroke. Further clinical trials are recommended. This trial is registered with NCT02065778.

    Full Text Available Leishmania infection in immunocompromised hosts is reported in the literature, mostly concerning human immunodeficiency virus infected patients. It is not well characterized in the context of stem cell transplantation. We report a rare case clinical case of visceral leishmaniasis after allogeneic bone marrow transplantation. A 50-year-old Caucasian male was referred to allogeneic bone marrow transplantation with a high-risk acute lymphoblastic B leukemia in first complete remission. Allogeneic SCT was performed with peripheral blood stem cells from an unrelated Portuguese matched donor. In the following months, patient developed mild fluctuating cytopenias, mostly thrombocytopenia (between 60 and 80∗109/L. The only significant complaint was intermittent tiredness. The common causes for thrombocytopenia in this setting were excluded—no evidence of graft versus host disease, no signs of viral or bacterial infection, and no signs of relapsed disease/dysplastic changes. The bone marrow smear performed 12 months after transplantation revealed an unsuspected diagnosis: a massive bone marrow infiltration with amastigotes.

  4. Regulatory Immunotherapy in Bone Marrow Transplantation

    2011-01-01

    Full Text Available Every year individuals receive hematopoietic stem cell transplantation (HSCT to eradicate malignant and nonmalignant disease. The immunobiology of allotransplantation is an area of ongoing discovery, from the recipient's conditioning treatment prior to the transplant to the donor cell populations responsible for engraftment, graft-versus-host disease, and graft-versus-tumor effect. In this review, we focus on donor-type immunoregulatory T cells, namely, natural killer T cells (NKT and regulatory T cells (Treg, and their current and potential roles in tolerance induction after allogeneic HSCT.

  5. Intractable Diseases Treated with Intra-Bone Marrow-Bone Marrow Transplantation

    Ming eLi

    2014-09-01

    Full Text Available Bone marrow transplantation (BMT is used to treat hematological disorders, autoimmune diseases and lymphoid cancers. Intra bone marrow-BMT (IBM-BMT has been proven to be a powerful strategy for allogeneic BMT due to the rapid hematopoietic recovery and the complete restoration of T cell functions. IBM-BMT not only replaces hematopoietic stem cells but also mesenchymal stem cells (MSMCs. MSMCs are multi-potent stem cells that can be isolated from bone marrow, umbilical cord blood, and adipose tissue. MSMCs play an important role in the support of hematopoiesis, and modify and influence the innate and adaptive immune systems. MSMCs also differentiate into mesodermal, endodermal and ectodermal lineage cells to repair tissues. This review aims to summarize the functions of bone marrow-derived- MSMCs, and the treatment of intractable diseases such as rheumatoid arthritis and malignant tumors with IBM-BMT.

  6. Bone marrow transplantation after the Chernobyl nuclear accident

    Baranov, A.; Gale, R.P.; Guskova, A.

    1989-01-01

    On April 26, 1986, an accident at the Chernobyl nuclear power station in the Soviet Union exposed about 200 people to large doses of total-body radiation. Thirteen persons exposed to estimated total-body doses of 5.6 to 13.4 Gy received bone marrow transplants. Two transplant recipients, who received estimated doses of radiation of 5.6 and 8.7 Gy, are alive more than three years after the accident. The others died of various causes, including burns (the cause of death in five), interstitial pneumonitis (three), graft-versus-host disease (two), and acute renal failure and adult respiratory distress syndrome (one). There was hematopoietic (granulocytic) recovery in nine transplant recipients who could be evaluated, six of whom had transient partial engraftment before the recovery of their own marrow. Graft-versus-host disease was diagnosed clinically in four persons and suspected in two others. Although the recovery of endogenous hematopoiesis may occur after exposure to radiation doses of 5.6 to 13.4 Gy, we do not know whether it is more likely after the transient engraftment of transplanted stem cells. Because large doses of radiation affect multiple systems, bone marrow recovery does not necessarily ensure survival. Furthermore, the risk of graft-versus-host disease must be considered when the benefits of this treatment are being weighed

    While cadaveric vertebral bodies (VB) have long been proposed as a suitable source of bone marrow (BM) for transplantation (BMT), they have rarely been used for this purpose. We have infused VB BM immediately following whole organ (WO) transplantation to augment donor cell chimerism. We quantified the hematopoietic progenitor cell (HPC) content of VB BM as well as BM obtained from the iliac crests (IC) of normal allogeneic donors (ALLO) and from patients with malignancy undergoing autologous marrow harvest (AUTO). Patients undergoing WOIBM transplantation also had AUTO BM harvested in the event that subsequent lymphohematopoietic reconstitution was required. Twenty-four VB BM, 24 IC BM-ALLO, 31 IC AUTO, and 24 IC WO-AUTO were harvested. VB BM was tested 12 to 72 hr after procurement and infused after completion ofWO grafting. IC BM was tested and then used or cryopreserved immediately. HPC were quantified by clonal assay measuring CFU-GM, BFU-E, and CFU-GEMM, and by flow cytometry for CD34+ progenitor cells. On an average, 9 VB were processed during each harvest, and despite an extended processing time the number of viable nucleated cells obtained was significantly higher than that from IC. Furthermore, by HPC content, VB BM was equivalent to IC BM, which is routinely used for BMT. We conclude that VB BM is a clinically valuable source of BM for allogeneic transplantation. PMID:7701582

  9. Bone marrow transplantation for thalassemia: a global perspective

    Mohamed Hamed Hussein

    2013-03-01

    Full Text Available Even though severe thalassemia is a preventable disease, over 100,000 new cases are born yearly, particularly in the Middle East and South-East Asia. Most of these children may not reach adulthood because long-term appropriate supportive care is either inaccessible or unaffordable. Bone marrow transplantation (BMT remains the only available definitive cure and success rates can be very high in appropriately selected patients, i.e. low-risk younger children with a matched family donor. In these circumstances BMT may be justified medically, ethically as well as financially, in fact, the cost of low-risk BMT is equivalent to that of a few years of non-curative supportive. This manuscript will briefly review the current status of bone marrow transplantation for thalassemia major with particular emphasis on a global prospective and present the experience of the Cure2Children Foundation supporting sustainable and scalable start up BMT programs in low-resource settings. The initial twelve consecutive patients managed in two start up BMT units in Pakistan (Children’s Hospital of the Pakistan Institute of Medical Sciences, Islamabad and India (South East Asia Institute for Thalassemia, Jaipur were included in this analysis. These initial six patients per each institution where purposely chosen as the focus of this report because they represent the steepest phase of the learning curve. The median age at transplant was 3.9 years, range 0.9 to 6.0, liver was no greater than 2 cm from costal margin, and all received matched related BMT. A structured on-site focused training program as well as ongoing intensive on-line cooperation was provided by the Cure2Children team of professionals. At a median follow-up of 7.5 months (range 3.5 to 33.5 months both thalassemia-free and overall survival are 92%, one patient died of encephalitis-meningitis of unknown cause. No rejections where observed. Neutrophil recovery occurred at a median of 15.5 days (range 13

    The purpose of this study is to investigate the role of femoral marrow MR imaging as predictor of outcome for hemopoietic stem cell transplantation (HSCT) in beta-thalassemia major. MR imaging of the proximal femur, including T1- and T2-weighted spin echo and short-tau inversion recovery and in-phase and out-of-phase fast field echo images, was prospectively performed in 27 thalassemia major patients being prepared for HSCT. The area of red marrow and its percentage of the proximal femur were measured, and the presence of marrow hemosiderosis was assessed. Age-adjusted multivariate logistic regression was used to determine the relationship between red marrow area percentage and marrow hemosiderosis and HSCT outcome. Red area percentage were less in patients with successful (90.25{+-}4.14%) compared to unsuccessful transplants (94.54% {+-}2.93%; p=0.01). Red marrow area percentage correlated positively with duration of symptoms(r=0.428, p=0.026) and serum ferritin (r=0.511, p=0.006). In multivariate-adjusted logistic regression analyses, red marrow area percentage was significantly inversely associated with successful HSCT (OR=1.383, 95% CI: 1.059-1.805, p=0.005). Marrow hemosidersosis and duration of sympotms and serum ferritin were not associated with HSCT outcome(p=0.174, 0.974, 0.762, respectively). Red marrow area percentage of proximal femur on MR imaging is a useful predictor of HSCT outcome. (orig.)

    Objective: Autologous bone marrow mononuclear cell transplantation is a treatment modality under investigation for severe coronary heart disease. Its beneficial effects on ventricular function, myocardial perfusion and metabolism remain to be evaluated. The present study proposed a 18 F-fluorodeoxyglucose (FDG) and 99 Tc m -methoxyisobutylisinitrile (MIBI) dual-isotope simultaneous acquisition (DISA) imaging technique to assess the effects of coronary artery bypass grafting (CABG) combined with autologous bone marrow mononuclear cell transplantation in patients with old myocardial infarction (OMI). Methods: Twenty patients with OMI, whose diagnosis was confirmed with angiography. were divided into a convention. al CABG group (group A, n=11) and CABG+ autologous bone marrow mononuclear cell transplantation group (group B, n=9). All subjects underwent gated cardiac DISA tomography at one week preoperatively and four months postoperatively. The segmental myocardial uptake of the tracers was scored as 3, 2, 1 and 0. Paired-samples t test was used to compare data of the two groups. Results In group A, there were 52 perfusion/metabolism mismatched segments, 99 Tc m -MIBI and 18 F-FDG uptake scores of these segments in-creased from preoperatively 1.48 ± 0.75( 99 Tc m -MIBI)and 1.90 ± 0.75( 18 F-FDG) to postoperatively 1.75 ± 0.68 and 2.13 ± 0.74 (t=3.25 and 2.37, both P 0.05). However, in group B, there was significant increase of the myocardial uptake scores both in mismatched segments and matched segments. In the 45 mismatched segments of this group,preoperative and postoperative 99 Tc m -MIBI/ 18 F-FDG uptake scores were 1.24 ± 0.68/1.71 ± 0.76 and 1.53 ± 0.66/2.00 ± 0.64, respectively (t=2.93 and 2.56. both P 99 Tc m -MIBI/ 18 F-FDG uptake scores were 0.94 ± 0.75/1.50 ± 0.74 and 1.22 ± 0.76/1.78 ± 0.64. respectively (t=2.71 and 3.37. both P 0.05).

  14. Cure of murine thalassemia by bone marrow transplantation without eradication of endogenous stem cells

    1986-01-01

    alpha-Thalassemic heterozygous (Hbath/+) mice were used to investigate the possible selective advantage of transplanted normal (+/+) hemopoietic cells. Without conditioning by total-body irradiation (TBI), infusion of large numbers of normal bone marrow cells failed to correct the thalassemic peripheral blood phenotype. Since the recipients' stem cells are normal with respect to number and differentiation capacity, it was thought that the transplanted stem cells were not able to lodge, or that they were not stimulated to proliferate. Therefore, a nonlethal dose of TBI was given to temporarily reduce endogenous stem cell numbers and hemopoiesis. TBI doses of 2 or 3 Gy followed by infusion of normal bone marrow cells proved to be effective in replacing the thalassemic red cells by normal red cells, whereas a dose of 1 Gy was ineffective. It is concluded that cure of thalassemia by bone marrow transplantation does not necessarily require eradication of thalassemic stem cells. Consequently, the objectives of conditioning regimens for bone marrow transplantation of thalassemic patients (and possibly other nonmalignant hemopoietic disorders) should be reconsidered

    Objective: To observe the tracing and evolution of marrow stromal cell (MSC) after intraportal transplantation into the liver of homogenous rats, and to provide experimental data for MSC differentiation to hepatocyte in vivo. Methods: The MSC was isolated from the leg bone marrow of adult SD rats, and purified by culture-expanded in vitro. Before transplantation, MSC was labeled with DAPI. Then 10 5 MSC were intraportally transplanted into the homogenous rat liver. Rats were killed at 2 hours and 1, 2, 3 and 4 weeks after transplantation. The cryosection samples of liver and lung were observed under fluorescence microscopy. Results: MSC in vitro culture had high ability of proliferation. Except 4 rats were dead because of abdominal bleeding or infection, other recipients were healthy until sacrificed. The implantation cells were detected by identifying the DAPI labeled MSC in the host livers, but not in the host lungs. Conclusion: Intraportal transplanted MSC could immigrate and survive in the host livers at least for 4 weeks. They could immigrate from the small branches of portal veins to hepatic parenchyma

    Unmanipulated haploidentical/mismatched related transplantation with combined granulocyte-colony stimulating factor-mobilised peripheral blood stem cells (G-PBSCs) and granulocyte-colony stimulating factor-mobilised bone marrow (G-BM) has been developed as an alternative transplantation strategy for patients with haematologic malignancies. However, little information is available about the factors predicting the outcome of peripheral blood stem cell (PBSC) collection and bone marrow (BM) harvest in this transplantation. The effects of donor characteristics and procedure factors on CD34(+) cell yield were investigated. A total of 104 related healthy donors received granulocyte-colony stimulating factor (G-CSF) followed by PBSC collection and BM harvest. Male donors had significantly higher yields compared with female donors. In multiple regression analysis for peripheral blood collection, age and flow rate were negatively correlated with cell yield, whereas body mass index, pre-aphaeresis white blood cell (WBC) and circulating immature cell (CIC) counts were positively correlated with cell yields. For BM harvest, age was negatively correlated with cell yields, whereas pre-BM collection CIC counts were positively correlated with cell yield. All donors achieved the final product of >or=6 x10(6) kg(-1) recipient body weight. This transplantation strategy has been shown to be a feasible approach with acceptable outcomes in stem cell collection for patients who received HLA-haploidentical/mismatched transplantation with combined G-PBSCs and G-BM. In donors with multiple high-risk characteristics for poor aphaeresis CD34(+) cell yield, BM was an alternative source.

    Full text: Total body irradiation (TBI) is a useful conditioning regimen for bone marrow transplantation (BMT), but has unacceptable toxicity in some patients. High doses of bone-seeking radiopharmaceuticals may offer a useful alternative to TBI in BMT patients with marrow-based tumours. Nine patients (5 multiple myeloma [MM], 2 leukaemia, 1 lymphoma, I myelodysplasia) were enrolled in a dose escalation protocol based upon retained skeletal activity. Infused doses have ranged between 18 and 32 GBq of 153 Sm-EDTMP in six patients treated. No adverse effects related to the infusion have been seen. Peripheral blood counts fell from day 7 post-treatment, persisting to the start of cytotoxic conditioning regimen at days 11-14 post-treatment. Five patients have engrafted, with one allogeneic transplant patient dying from acute rejection. Pre-treatment dosimetry was performed by gamma camera and whole-body probe counts. Post-therapy activities were estimated by serial dose meter readings and gamma camera images. The pre-treatment skeletal retention by gamma camera was 1.7-2.4 times the values based on probe data. Retained post-treatment skeletal activity predicted by dosimetry was significantly greater than that actually measured, confirmed in one case by urinary collection. This latter fact is most likely due to the nature of the interaction of 153 Sm-EDTMP with bone at high doses

  18. HLA matching in unrelated donor bone marrow transplantation.

    Charron, D J

    1996-11-01

    The availability of an HLA-matched sibling donor in only 30% to 35% of patients requiring allogeneic bone marrow transplantation (BMT) has led to the proposal of unrelated donors as an alternative source of bone marrow. The greater HLA incompatibility, which, although present, was undetected until recently in many unrelated donor BMT cases, has resulted in a higher rate of posttransplant complications and impaired acturial survival when compared with HLA-matched sibling BMT. Molecular HLA typing enables us to evaluate the impact of incompatibility at each locus in the outcome of unrelated donor BMT. The overall retrospective data would recommend that HLA-A, -B and -C allelic molecular matching should be implemented in addition to HLA-DR allelic matching. Further retrospective analysis is needed in order to assess which incompatibility or combinations are better tolerated than others. Only the definitive knowledge at the sequence level of the donor and the recipient HLA allelic diversity involved in controlling the allogeneic immune response will allow us to understand the precise biologic rationale of the graft-versus-host disease. Knowledge and control of the HLA incompatibilities should allow us to offset the detrimental effects of histoincompatibility while developing strategies to take advantage of the beneficial graft-versus-leukemia effect. Also the role of minor histocompatibility antigens remains largely unknown and will require careful evaluation before minor antigens can be used as a selection criterion in BMT. Carefully designed prospective studies will enable us to test the impact of each HLA locus. HLA typing and BMT represent a successful example of productive cooperation between basic and clinical sciences that should be pursued for the improvement of the clinical outcome of unrelated donor BMT.

    Preventing the propagation of radiation induced oxidative damage has been a subject of considerable investigations. The ultimate goal of the present study is to use bone marrow cells to ameliorate or to treat the radiation sickness. Transplantation of bone marrow cell has shown promising results in the present experimental radiation treatment. In this report, suspension of bone marrow cells was injected into rats 12 h. after exposure to 4.5 Gy whole body gamma irradiation. Significant results were recorded on the successful control of the radiation induced disorders in a number of biochemical parameters including certain enzymatic and nonenzymatic antioxidants (superoxide dismutase and glutathione) and certain parameters related to kidney function including creatinine, urea as well as Atpase Activity in blood serum, urine and kidney tissue

  20. Genetic resistance to marrow transplantation as a leukemia defense mechanism

    Gallagher, M.T.; Lotzova, E.; Trentin, J.J.

    1976-01-01

    The normal role of genetic resistance to bone marrow transplantation was investigated. It is demonstrated, using three different systems e.g. colony studies in the spleen, spleen weight studies and mortality studies, that irradiated or unirradiated mice which show genetic resistance are able to recognize and reject intravenously transplanted parental lymphoma cells, while they accept normal parental bone marrow cells. Either the lymphoma cells have a new antigen which is recognized and reacted to by the cells responsible for genetic resistance and, or, bone marrow cells have a low level of Hh antigen which is increased greatly by the lymphoma transformation process, thereby resulting in the rejection of the lymphoma cells by the cells responsible for genetic resistance. Lymphoma resistance as well as genetic resistance can be overridden by increasing the number of cells injected. Genetic resistance seems to be restricted to the spleen and bone marrow. There is evidence that the normal biological role for genetic resistance may be lymphoma-leukemia surveillance

  1. Sclerodermatous GVHD after Allogeneic Bone Marrow Transplant: a Review

    Gagan Raju

    2017-05-01

    Full Text Available Chronic graft versus host disease (cGVHD is the leading cause of non-relapse mortality after allogeneic hematopoietic bone marrow transplantation (HCT for blood malignancy in patients who survive for more than two years. cGVHD can significantly affect quality of life and cause decreased mobility amongst other grave consequences such as end-organ damage, contributing to morbidity and mortality rates for recipients of HCT. Unlike acute GVHD (aGVHD, the chronic variant of graft versus host disease (GVHD has complex immunopathology involving both humoral and cell immunity. It typically affects the integumentary system, though is known to also affect myofascial, mucocutaneous tissues as well as cause end organ damage ultimately resulting in death. Sclerodermatous cGVHD is a type of cGVHD characterized by involvement of the skin, subcutaneous tissue and fascia without evidence of disease in the viscera. Manifestations of this disease are often evocative of autoimmune disease, which is a self-directed inflammatory reaction to the innate and adaptive immune system in various tissues or multiple organ systems. This inflammatory reaction gives rise to autoantibodies as well as B-cell and T-cell mediated direct toxicity which can cause chronic inflammatory changes of tissues ultimately resulting in tissue scarring and end organ dysfunction. We aim to review the literature on this grave disease and elucidate aspects of the immunopathology of chronic sclerodermatous GVHD in hopes that it may lead to revelations inspiring novel therapies after its diagnosis or preventative measures before stem cell transplantation for malignancy.

  2. The role of total body irradiation in preparation for bone marrow transplantation in acute leukaemia. A review

    Zwaan, F.E.

    1979-01-01

    From extrapolation obtained from animal studies and radiation accidents, it is assumed that for man the LD 50 (30) will be between 300-500 rads total body irradiation (TBI) and the LD 100 at least 600 rads TBI. A dose of 1000 rads TBI is generally used in man for conditioning for bone marrow transplantation. In acute leukemia, total body irradiation is usually associated with cytoreductive chemotherapy. In Seattle 110 patients underwent bone marrow transplantation for acute leukemia in relapse. 15 patients became long term survivors. The main cause of failure were GVH, interstitial pneumonitis and leukemic relapse. New attempts are being made to improve the results: (1) better cytoreductive therapy preceding transplantation, (2) bone marrow transplantation during remission of the disease, (3) prevention of interstitial pneumonitis by modifications of the TBI technique

    To characterise bone marrow derived cells in the sclera under normal and inflammatory conditions, we examined their differentiation after transplantation from two different sources, bone marrow and haematopoietic stem cells (HSC). Bone marrow and HSC from green fluorescent protein (GFP) transgenic mice were transplanted into irradiated wild-type mice. At 1 month after transplantation, mice were sacrificed and their sclera examined by histology, immunohistochemistry (CD11b, CD11c, CD45), and transmission and scanning electron microscopy. To investigate bone marrow derived cell recruitment under inflammatory conditions, experimental autoimmune uveitis (EAU) was induced in transplanted mice. GFP positive cells were distributed in the entire sclera and comprised 22.4 (2.8)% (bone marrow) and 28.4 (10.9)% (HSC) of the total cells in the limbal zone and 18.1 (6.7)% (bone marrow) and 26.3 (3.4)% (HSC) in the peripapillary zone. Immunohistochemistry showed that GFP (+) CD11c (+), GFP (+) CD11b (+) cells migrated in the sclera after bone marrow and HSC transplantation. Transmission and scanning electron microscopy revealed antigen presenting cells among the scleral fibroblasts. In EAU mice, vast infiltration of GFP (+) cells developed into the sclera. We have provided direct and novel evidence for the migration of bone marrow and HSC cells into the sclera differentiating into macrophages and dendritic cells. Vast infiltration of bone marrow and HSC cells was found to be part of the inflammatory process in EAU.

    2004-01-01

    To evaluate the high resolution computed tomography (HRCT) findings of bronchiolitis obliterans (BO) after bone marrow transplantation (BMT). During the past three years, 11 patients were diagnosed as having BO after BMT when they developed irreversible air flow obstruction, with an FEV 1 value of less than 80% of the baseline value, without any clinical evidence of infection. All 11 patients underwent HRCT, of whom eight also underwent follow-up HRCT. The HRCT images were assessed retrospectively for the presence of decreased lung attenuation, segmental or subsegmental bronchial dilatation, diminution of peripheral vascularity, centrilobular nodules, and branching linear structure on the inspiratory images. The lobar distribution of the decreased lung attenuation and bronchial dilatation was also examined. The presence of air trapping was investigated on the expiratory images. The interval changes of the HRCT findings were evaluated in those patients who had follow-up images. Abnormal HRCT findings were present in all cases; the most common abnormalities were decreased lung attenuation (n=11), subsegmental bronchial dilatation (n=6), diminution of peripheral vascularity (n=6), centrilobular nodules or branching linear structure (n=3), and segmental bronchial dilatation (n=3). Expiratory air trapping was noted in all patients. The decreased lung attenuation and bronchial dilatations were more frequent or extensive in the lower lobes. Interval changes were found in all patients with follow-up HRCT: increased extent of decreased lung attenuation (n=7); newly developed or progressed bronchial dilatation (n=4); and increased lung volume (n=3). HRCT scans are abnormal in patients with BO, with the most commonly observed finding being areas of decreased lung attenuation. While the HRCT findings are not specific, it is believed that their common features can assist in the diagnosis of BO in BMT recipients

    1997-01-01

    We present the imaging findings in a patient with mucopolysaccharidosis (MPS) type VI (Maroteaux-Lamy syndrome) who developed holocord syringomyelia. This represents the only reported case of syrinx formation in a child with MPS VI. Clinical, neurologic and spinal magnetic resonance imaging findings are presented. The patient has maintained a stable clinical and neurologic course over the period following allogeneic bone marrow transplant. (orig.). With 3 figs

  6. Endocrine dysfunction after total body irradiation and bone marrow transplantation

    Feyer, P.; Titlbach, O.; Hoffmann, F.A.; Kubel, M.; Helbig, W.; Leipzig Univ.

    1989-01-01

    Data regarding changes of endocrine parameters after total body irradiation (TBI) and bone marrow transplantation (BMT) are described. Endocrine glands are usually resistant to irradiation under morphological aspects. But new methods of determination and sensitive tests were developed in the last few years. Now it is possible to detect already small functional changes. Endocrine studies in the course of the disease were followed serially in 16 patients with TBI and BMT. Pretransplant conditioning consisted of single-dose irradiation combined with a high-dose, short-term chemotherapy. Reactions of the endocrine system showed a defined temporary order. Changes of ACTH and cortisol were in the beginning. The pituitary-adrenal cortex system responds in a different way. The pituitary-thyroid system develops a short-term 'low-T 3 -syndrome' reflecting the extreme stress of the organism. At the same time we obtained an increase of thyroxine. Testosterone and luteotropic hormone, the sexual steroids showed levels representing a primary gonadal insufficiency. The studies in the posttransplant period yielded a return to the normal range at most of the hormonal levels with the exception of the sexual steroids. Sterility is one of the late effects of TBI. A tendency towards hypothyroidism could be noticed in some cases being only subclinical forms. Reasons and possible therapy are discussed. (author)

  7. Single dose total lymphoid irradiation combined with cyclophosphamide as immunosuppression for human marrow transplantation in aplastic anemia

    1979-01-01

    Six patients with aplastic anemia underwent bone marrow transplantation following conditioning with high dose cyclophosphamide and single dose total lymphoid irradiation with 750 rad, 26 rad/min at the midplane of the patient. They all received bone marrow from human leukocyte antigens/mixed lymphocyte culture (HLA/MLC) matched siblings. Five of 6 patients were alive without complications at 12, 11, 7, 4 and 4 months respectively. The remaining patient died from sepis which he had prior to transplantation. There were no graft rejection, graft-vs-Host Disease (GVHD) or interstitial pneumonitis among these patients. The procedure was well tolerated with minimal side effects. The results will be compared with those of groups whose bone marrow was previously transplanted with different immunosuppressive methods

  8. Cytogenetic studies on recipients of allogeneic bone marrow transplants after fractionated total body irradiation

    1985-06-01

    Cytogenetic findings from the bone marrow (BM) and the peripheral blood (PB) of nine consecutive patients after allogeneic bone marrow transplantation (BMT) for acute or chronic myelogenous leukaemia are reported. After a conditioning regimen consisting of cyclophosphamide and fractionated total body irradiation (TBI) given in five or six fractions of 2 Gy, persistence of host cells was detected in four out of seven cases with permanent engraftment. While one of these patients relapsed 4 months after host cells had been found in BM and PB, the other patients stayed relapse-free 124, 257 and 347 d after grafting. Before transplantation, the leukaemic cells in all three cases carried unique cytogenetic abnormalities giving the opportunity to distinguish the leukaemic population from chromosomally non-aberrant cells thought to represent residual normal host cells. As the persisting host cells after BMT lacked any cytogenetic abnormalities, it is suggested that they were members of residual normal clones not involved in the leukaemic process.

  9. Invasive central nervous system aspergillosis in bone marrow transplantation recipients: an overview

    Guermazi, Ali; Gluckman, Eliane; Tabti, Bachir; Miaux, Yves

    2003-01-01

    Invasive central nervous system aspergillosis is being seen with an increased frequency, particularly due to the increased number of immunosuppressed patients. The major cause of invasive central nervous system aspergillosis is bone marrow transplantation. In most cases, aspergillosis develops in the paranasal sinuses and in the lungs, and secondarily spreads to the brain. Imaging of cerebral aspergillosis may present different patterns depending on the lesion's age and the immunologic status of the patient. Lesions of the spinal cord are far less common but has been encountered in our series. In this article we review the clinical and radiologic features of aspergillosis affecting the central nervous system in patients who underwent bone marrow transplantation. Different CT and MR patterns are presented, including pertinent clinical and pathologic material. Significant morbidity and mortality can be associated with this fungal infection, and it is therefore incumbent upon the radiologist to identify intracranial aspergillosis as early as possible so that appropriate therapy can be administered.

    1996-01-01

    We present two cases of osteochondroma after total body irradiation in bone marrow recipients, the first in a 6-year-old boy with juvenile chronic myelogenous leukemia and the second in a 13-year-old boy with acute myelogenous leukemia. The patients developed multiple osteochondromas three years and seven years, respectively, after 12 Gy of total body irradiation. Neither had a family history of hereditary multiple osteochondromatosis. A review of the English literature revealed only one report describing five cases of osteochondroma after 12 Gy of total body irradiation in bone marrow transplant recipients. Osteochondroma should be considered as an additional adverse effect of total body irradiation. (author)

  12. Clinical studies on bone marrow transplantation of acute leukemia and aplastic anemia

    Morishima, Yasuo

    1979-01-01

    Since 1974, we have done bone marrow transplantation (BMT) in six patients of acute leukemia and two of aplastic anemia. Leukemia patients were premedicated by CY+TBI method; cyclophosphamide (CY) 60 mg/kg/day was administered for two successive days and two days later, total body irradiation (TBI) was done in a dose of 800 - 1000 rad at a rate of 20-28 rad/min by linear accerelator. Patients with aplastic anemia were premedicated by CY method; CY 50 mg/kg/day for four successive days. Bone marrow graft was obtained from donor under general anesthesia. The nucleated bone marrow cells, ranged from 0.7 x 10 10 to 1.4 x 10 10 were transfused into the patient intravenously. Any lethal side effects did not develop in all patient during these procedures. Two died on day 10 and 12 with septicemia. The other 6 patients showed engraftment of bone marrow indicated by rising blood counts, return of marrow cellularity and in one case by blood cytogenetic markers. Relapse of leukemia did not occur in five patients treated with CY + TBI method. Three patients with allogeneic BMT developed moderately severe to severe Graft versus Host Disease. Survival time after BMT were 12, 35, 63, 68, 98, 125 days. 15 months in leukemia, and 10 days, 12 + months in aplastic anemia. (author)

  13. Successful repigmentation of vitiligo after allogeneic bone marrow transplantation for Hodgkin′s lymphoma by autologous noncultured melanocyte-keratinocyte transplantation

    Huijuan Tang

    2015-01-01

    Full Text Available The treatment of vitiligo is derisory since the pathogenesis of vitiligo is not clear at present. Most conservative treatments are difficult to approach satisfactory therapy. So transplantation is the only way left when the disease becomes insensitive to those conservative treatments. Here we describe an 18-year-old patient who developed vitiligo, which was triggered by graft-versus-host disease after a allogeneic bone marrow transplantation for the treatment of Hodgkin′s lymphoma from his sister. In the following treatment to vitiligo, the patient successfully performed the transplantation of autologous uncultured melanocyte on the premise of poor reaction to other conservative methods. We infer that transplantation can be a treatment of the vitiligo after allogeneic bone marrow transplantation.

    1982-01-01

    The LD50 of total body irradiation (TBI) for the bone marrow (BM) syndrome and the gastrointestinal (GI) syndrme was determined in dogs as 3.7 Gy, and 8.5 Gy respectively. Five Gy TBI was adequate conditioning for BM cells of littermate donors identical for the major histocompatibility comples (MHC). The maximum tolerated TBI (about 7.5 Gy) caused more side effects than 5.0 Gy TBI and was insufficient for engraftment of realistic numbers of BM cells of MHC mismatched donors. In autologous and MHC matched transplants, the rateof hemopoietic recovery correlated with the number of BM cells given. Approximtely 2 x 10 7 autologous and 1 x 10 8 MHC identical BM cells.kg -1 were needed for radiation protection. Platelet recovery was significantly more rapid in allogeneic combinations in comparison to autologous transplants. Low numbers of autologous cryopreserved bone marrow cells were as effective as fresh bone marrow cells in rescuing animals after lethal TBI. Other factors that influence BM cell engraftment were confirmed (prior sensitization of the recipient, donor selection) or identified (purification of BM cells on density gradient and selective gastrointestinal decontamination of the recipient). Consistent engraftment of gradient separated, MHC identical, BM cells was found after conditioning with two fractions of 6.0 Gy TBI, separated by 72 h. One MHC haplotype mismatched marrow did engraft after two TBI fractions of 6.0 Gy. Engraftment no longer occurred with gradient purified bone marrow cells from this type of donor. Late effects of TBI were early greying in all animals, and secondary uterine inertia in female dogs after 7.5 GY TBI. Fertility in males or females was not changed by radiation. An increase of pancreas fibrosis was noted in dogs receiving fractions of 6.0 Gy TBI. (author)

  15. Successful bone marrow transplantation in a patient with Diamond-Blackfan anemia with co-existing Duchenne muscular dystrophy: a case report

    2011-06-01

    Full Text Available Abstract Introduction Diamond-Blackfan anemia and Duchenne muscular dystrophy are two rare congenital anomalies. Both anomalies occurring in the same child is extremely rare. Allogeneic hematopoietic stem cell transplantation is a well-established therapy for Diamond-Blackfan anemia. However, in patients with Duchenne muscular dystrophy, stem cell therapy still remains experimental. Case presentation We report the case of a nine-year-old boy of north Indian descent with Diamond-Blackfan anemia and Duchenne muscular dystrophy who underwent successful allogeneic hematopoietic stem cell transplantation. He is transfusion-independent, and his Duchenne muscular dystrophy has shown no clinical deterioration over the past 45 months. His creatine phosphokinase levels have significantly decreased to 300 U/L from 14,000 U/L pre-transplant. The patient is 100% donor chimera in the hematopoietic system, and his muscle tissue has shown 8% to 10.4% cells of donor origin. Conclusion Our patient's Diamond-Blackfan anemia was cured by allogeneic hematopoietic stem cell transplantation. The interesting clinical observation of a possible benefit in Duchenne muscular dystrophy cannot be ruled out. However, further clinical follow-up with serial muscle biopsies and molecular studies are needed to establish this finding.

    2003-01-01

    Objective: To identify homing of bone marrow cells after every fractionation during scheduled transplantation. Methods: The recipient mice were transplanted with homologous (H-2K d ) and allogeneic (H-2K b ) mouse bone marrow cells after lethal irradiation, and the homing status of allogeneic bone marrow cells in host bone marrow and spleen was observed. Results: A quantity of allogeneic homed cells were observed in host bone marrow, and the percentage of homing cells in second fraction was the highest in all groups (P<0.01). The allogeneic homed cells in spleen declined along with increase of the number of fraction, suggesting that regulation of homing to spleen was different from that to bone marrow. Conclusion: In scheduled bone marrow transplantation niche may be more effectively utilized and thus transplantation efficiency be enhanced

  17. Efficacy of Surgery Combined with Autologous Bone Marrow Stromal Cell Transplantation for Treatment of Intracerebral Hemorrhage

    2015-01-01

    Full Text Available Bone marrow stromal cells (BMSCs may differentiate into nerve cells under a certain condition; however, the clinical application for treating nervous system disease remains unclear. The aim is to assess the safety profile, feasibility, and effectiveness of surgery combined with autologous BMSCs transplantation for treating ICH. 206 ICH patients who had received surgical procedure were divided into transplantation (n=110 or control group (n=96. For transplantation group, BMSCs were injected into the perihemorrhage area in the base ganglia through an intracranial drainage tube 5.5 (3.01–6.89 days after surgery, followed by a second injection into the subarachnoid space through lumbar puncture 4 weeks later. Neurologic impairment and daily activities were assessed with National Institute Stroke Scale (NIHSS, Barthel index, and Rankin scale before transplantation and 6 months and 12 months after transplantation. Our results revealed that, compared with control group, NIHSS score and Rankin scale were both significantly decreased but Barthel index was increased in transplantation group after 6 months. Interestingly, no significant difference was observed between 12 months and 6 months. No transplantation-related adverse effects were investigated during follow-up assessments. Our findings suggest that surgery combined with autologous BMSCs transplantation is safe for treatment of ICH, providing short-term therapeutic benefits.

    In most treatment algorithms, osteochondral allograft (OCA) transplantation is regarded as an alternative salvage procedure when other, previous reparative treatments have failed. To compare the outcomes of a retrospective matched-pair cohort of (1) primary OCA transplantation and (2) OCA transplantation after failure of previous subchondral marrow stimulation. Cohort study; Level of evidence, 3. An OCA database was used to identify 46 knees that had OCA transplantation performed as a primary treatment (group 1) and 46 knees that underwent OCA transplantation after failure of previous subchondral marrow stimulation (group 2). All patients had a minimum of 2 years' follow-up. Patients in each group were matched for age (±5 years), diagnosis (osteochondral lesion, degenerative chondral lesion, traumatic chondral injury), and graft size (small, 10 cm2). The groups had similar body mass indexes, sex distributions, and graft locations (femoral condyle, patella, and trochlea. The number and type of further surgeries after the OCA transplantation were assessed; failure was defined as any reoperation resulting in removal of the graft. Functional outcomes were evaluated by use of the modified Merle d'Aubigné-Postel (18-point) scale, International Knee Documentation Committee (IKDC) subjective knee evaluation form, Knee injury and Osteoarthritis Outcomes Score (KOOS), and the Knee Society function (KS-F) scale. Patient satisfaction, according to a 5-point scale from "extremely satisfied" to "dissatisfied," was recorded at the latest follow-up. Eleven of 46 knees (24%) in group 1 had reoperations, compared with 20 of 46 knees (44%) in group 2 (P = .04). The OCA was classified as a failure in 5 knees (11%) in group 1 and 7 knees (15%) in group 2 (P = .53). At 10 years of follow-up, survivorship of the graft was 87.4% and 86% in groups 1 and 2, respectively. Both groups showed improvement in pain and function on all subjective scores from preoperatively to the latest follow

    1989-03-01

    Between August 1985 and October 1987 35 patients with chronic myeloid leukaemia (CML) were treated by high dose chemotherapy, total body irradiation (TBI) (1000 or 1200 cGy, n=31) and total lymphoid irradiation (TLI) (800 or 600 cGy, n=35) preceding allogeneic bone marrow transplantation (BMT). Both TBI and TLI were given at 200 cGy/fraction. Twenty-three patients had HLA-identical sibling donors, nine patients had HLA-matched but unrelated donors, and three partially HLA-mismatched donors. Twenty-two patients received T-cell depleted marrow. TLI did not add greatly to the toxicity. Four patients had recurrent leukaemia before engraftment was evaluable. The other 31 patients engrafted and no graft failed. Twenty-two patients survive at a median time from transplant of 305 days (range 81-586 days). Fourteen have no evidence of disease; eight have or had only cytogenetic evidence of leukaemia. It is concluded that addition of TLI to pretransplant immunosuppression increases the probability of reliable engraftment in patients receiving T-cell depleted marrow. This is not associated with significantly increased toxicity. (author).

    Between August 1985 and October 1987 35 patients with chronic myeloid leukaemia (CML) were treated by high dose chemotherapy, total body irradiation (TBI) (1000 or 1200 cGy, n=31) and total lymphoid irradiation (TLI) (800 or 600 cGy, n=35) preceding allogeneic bone marrow transplantation (BMT). Both TBI and TLI were given at 200 cGy/fraction. Twenty-three patients had HLA-identical sibling donors, nine patients had HLA-matched but unrelated donors, and three partially HLA-mismatched donors. Twenty-two patients received T-cell depleted marrow. TLI did not add greatly to the toxicity. Four patients had recurrent leukaemia before engraftment was evaluable. The other 31 patients engrafted and no graft failed. Twenty-two patients survive at a median time from transplant of 305 days (range 81-586 days). Fourteen have no evidence of disease; eight have or had only cytogenetic evidence of leukaemia. It is concluded that addition of TLI to pretransplant immunosuppression increases the probability of reliable engraftment in patients receiving T-cell depleted marrow. This is not associated with significantly increased toxicity. (author)

  1. Bone marrow transplantation (1958-1978): conditioning and graft-versus-host disease, indications in aplasias and leukemias

    Mathe, G; Schwarzenberg, L [Hopital Paul Brousse, 94 - Villejuif (France)

    1979-06-01

    Bone marrow transplantation (BMT), which stimulated great hope for treatment of aplasias and leukemias in 1958 following our first success in grafting this tissue, is, after a long period of study and development, experiencing renewed interest since it is now possible to obtain, in case of transplantation with genotypically matched sibling donors, 70% long survival (cures) in aplasia (under the condition that the recipient is not sensitized by previous transfusions) and in leukemia (under the condition that the recipient is transplanted in a period of remission and is not sensitized by transfusions). When the patient does not possess any genotypically matched donor, a trial of incompatible bone marrow transplantation after conditioning with antilymphocyte serum is reasonable, since we have obtained good, although unexplained, results with this method, which should be pursued. In any case, these transplants must be done in intensive care units in hemato-oncology departments.

    Toxoplasmosis encephalitis is a severe, but often misdiagnosed complication in patients after bone marrow transplantation (BMT). We describe the unique computed tomography (CT) and magnetic resonance (MR) imaging features of cerebral toxoplasmosis in two bone marrow recipients and compare them to the cases in the literature. To our knowledge, this is the first report analyzing the appearance of cerebral toxoplasmosis on diffusion-weighted MR imaging (DWI). (orig.)

  6. Megakaryocytopoiesis and the number of thrombocytes after bone marrow cell transplantation in lethally irradiated mice

    Viktora, L.; Hermanova, E.; Zoubkova, M.

    1977-01-01

    Changes were studied in the number of thrombocytes in the peripheral blood and megakaryocytes in the bone marrow and spleen in lethally irradiated mice after the transplantation of bone marrow cells. It was found that the thrombocytes increased in dependence on time after transplantation with the maximal values around the 20th day. An increased megakaryocytopoiesis was observed not only in the bone marrow but also in the spleen. These ascertainments suggest the importance of the transplantation of bone marrow cells and the role of thrombocytes for the survival of the organism after irradiation. (author)

  7. Disturbances in dental development after total body irradiation in bone marrow transplant recipients

    1988-01-01

    The dental status of 16 children who had been treated with bone marrow transplantation (BMT) for serious bone marrow diseases was followed for up to 6 years. Several types of disturbances in dental development were observed in children who had been conditioned with total body irradiation (TBI) at 10 Gy before BMT. Thus, impaired root development that caused short V-shaped roots was found in all patients, a complete failure of root development and premature apical closure were found in five patients, enamel hypoplasia was observed in four patients, and microdontia was observed in three patients conditioned with TBI. Patients younger than 6 years of age at BMT exhibited the most severe and extensive dental aberrations. The TBI at 10 Gy appeared to be the major cause of the disturbances found

  8. Eosinophilic spleen colonies are produced in rat-marrow-transplanted but not in murine-marrow-transplanted mice

    Szabo, L.G.; Kelemen, E.

    1988-01-01

    Differential counts of about 5000 splenic clusters and colonies developing in whole-body-irradiated mice and rats were made, using semi-serial histological sections prepared 9 to 12 d after transplantation with bone marrow haemopoietic cells. The investigated mouse and rat spleens were from syngeneically, allogeneically, or xenogeneically transplanted recipients. Splenic eosinophil clusters were always found when rat eosinophil-producing progenitors were present in the inoculum, whereas murine inocula failed to produce splenic eosinophilic clusters even in the syngeneic mouse. The limiting factor in the production pf splenic eosinophilic clusters was the appropriate donor progenitor/committed stem cell itself. Changes in the percentages of eosinophil clusters with the number of injected cells and with increased doses of irradiation, as well as formation of rat eosinophil colonies in mice, as against mainly clusters in rats, themselves show that regulatory mechanisms of the recipients also play a role. These regulatory mechanisms cannot be attributed to the splenic microenvironment. (author)

    Kempen-Harteveld, M. Loes van; Struikmans, Henk; Kal, Henk B.; Tweel, Ingeborg van der; Mourits, Maarten P.; Verdonck, Leo F.; Schipper, Jan; Battermann, Jan J.

    2002-01-01

    Purpose: To assess the degree of visual impairment as a result of cataract formation after total body irradiation (TBI) for bone marrow transplantation. Methods and Materials: The data from 93 patients who received TBI in 1 or 2 fractions as a part of their conditioning regimen for bone marrow transplantation were analyzed with respect to the degree of visual impairment as a result of cataract formation. The probability to develop severe visual impairment (SVI) was determined for all patients, and the degree of visual impairment was assessed for 56 patients with stabilized cataract, using three categories: no, mild, or severe. Results: For all 93 patients, the probability of developing a cataract causing SVI was 0.44. For allogeneic patients, it was 0.33 without and 0.71 with steroid treatment (p<0.001). All SVI-free probability curves reached a plateau distinct from the cataract-free curves. Apparently, cataracts developing late in the follow-up period rarely cause SVI. Of the patients with stabilized cataract, 32% had no visual impairment, 16% had mild, and 52% severe impairment. No or mild visual impairment was present in 61% of all patients with stable cataract and no steroid treatment compared with only 13% of the patients treated with steroids (p=0.035). Conclusion: SVI occurs in only some of the patients (52%) with stable cataract after TBI for bone marrow transplantation in 1 or 2 fractions. Steroid treatment markedly increases the probability of developing visual problems as result of a cataract after TBI

    Purpose The purpose of this study was to compare medications and potential risk factors between patients who experienced a fall during hospitalization compared to those who did not fall while admitted to the Blood and Marrow Transplant inpatient setting at The James Cancer Hospital. Secondary objectives included evaluation of transplant-related disease states and medications in the post-transplant setting that may lead to an increased risk of falls, post-fall variables, and number of tests ordered after a fall. Methods This retrospective, case-control study matched patients in a 2:1 ratio of nonfallers to fallers. Data from The Ohio State University Wexner Medical Center (OSUWMC) reported fall events and patient electronic medical records were utilized. A total of 168 adult Blood and Marrow Transplant inpatients with a hematological malignancy diagnosis were evaluated from 1 January 2010 to 30 September 2012. Results Univariable and multivariable conditional logistic regression models were used to assess the relationship between potential predictor variables of interest and falls. Variables that were found to be significant predictors of falls from the univariable models include age group, incontinence, benzodiazepines, corticosteroids, anticonvulsants and antidepressants, and number of days status-post transplant. When considered for a multivariable model age group, corticosteroids, and a cancer diagnosis of leukemia were significant in the final model. Conclusion Recent medication utilization such as benzodiazepines, anticonvulsants, corticosteroids, and antidepressants placed patients at a higher risk of experiencing a fall. Other significant factors identified from a multivariable analysis found were patients older than age 65, patients with recent corticosteroid administration and a cancer diagnosis of leukemia.

    1985-01-01

    Fifty-six patients, 30-47 yr of age, with leukemia in relapse received allogeneic marrow transplants from HLA-identical siblings. All patients were treated with cyclophosphamide (120 mg/kg) and 7 daily fractions of 2.25 Gy of total body irradiation (TBI) for seven consecutive days. Nine patients (16%) are currently alive, free of disease, 324-845 days from transplantation. Actuarial relapse and survival rates at 2 yr were 56% and 9.5% respectively. These data were not remarkably different from those in previous studies using 10 Gy of TBI administered as a single dose. Thirty patients were randomized to receive methotrexate (MTX) and 26 to receive cyclosporine (CSP) as postgrafting prophylaxis for acute graft-versus-host disease (GVHD). Probability of developing significant acute GVHD by day 100 post-transplant was 71% for patients in the MTX group and 45% for patients in the CSP group (p<0.05). Probability of relapse was 37% for patients in the MTX group and 70% for patients in the CSP group (p<0.05). Transplant-related deaths were more frequent in the MTX group and leukemic deaths more frequent in the CSP group although this may have been related to an uneven distribution of high-risk patients. Long term disease-free survival was comparable. (author)

    We analysed the outcome of a second allogeneic haematopoietic stem cell transplant (alloHSCT) in 162 patients reported to the European Society for Blood and Marrow Transplantation between 1998 and 2009. Donor origin was a sibling in 110 and an unrelated donor in 52 transplants, respectively. The stem cell source was bone marrow in 31% and peripheral blood in 69% of transplants. The same donor as for the first alloHSCT was used in 81% of transplants whereas a change in the choice of stem cell source was reported in 56% of patients, mainly from bone marrow to peripheral blood. Neutrophil and platelet engraftment occurred in 85% and 72% of patients, after a median time of 15 and 17 days, respectively. Grade II-IV acute graft-versus-host disease (GVHD) and chronic GVHD occurred in 21% and 37% of patients, respectively. Graft failure (GF) occurred in 42 patients (26%). After a median follow-up of 3·5 years, the 5-year overall survival (OS) was 60·7%. In multivariate analysis, the only factor significantly associated with a better outcome was a Karnofsky/Lansky score ≥80 (higher OS). We conclude that a second alloHSCT is feasible rescue option for GF in SAA, with a successful outcome in 60% of cases. © 2015 John Wiley & Sons Ltd.

    2013-06-01

    We describe a rare case of fatal mumps encephalomyelitis occurring in 19-year old male following matched unrelated donor peripheral blood haematopoietic stem cell transplantation (HSCT). The indication for HSCT was for an undefined form of severe combined immunodeficiency (SCID). Molecular typing of the mumps viral RNA isolated from neural tissue indicated that the infection was acquired at the time of a mumps outbreak in England and Wales that occurred between 2004 and 2006. This case highlights the importance of considering mumps in the differential diagnosis of central nervous system infection in highly immunosuppressed patients. Copyright © 2013 Elsevier B.V.

    The usefulness of cytotoxic T lymphocytes (CTLp) frequency analysis in the search for donors in bone marrow transplantation was studied. The frequency of anti-recipient CTLp was approached by limiting dilution assay in HLA matched unrelated, HLA partially matched related and HLA genotypically identical donors. The majority of patients examined were affected with different hematological malignancies. Allo-reactive CTLp recognizing non-HLA gene products were not detected in pre-transplant examination of two pairs of HLA identical siblings. However, an increase incidence of allo-specific CTLp was identified in HLA matched mixed lymphocyte culture (MLC) negative unrelated pairs. Thus, CTLp assay allowed to the residual Class I incompatibilities that remained hidden in standard serotyping. In two matched unrelated pairs with high pretranslant CTLp frequency the severe acute graft-versus-host diseases developed after bone marrow transplantation. Examination of other relatives in patients lacking an HLA identical sibling showed the importance of Class I incompatibility for CTLp generation as well. The lack of correlation between CTLp frequency and HLA-D disparity could suggest that Class II antigens do not participate in CTLp induction. With one exception we had good correlation between MLC and DNA analysis of Class II antigens demonstrating that MLC gives interpretable results even in unrelated pairs. Our results demonstrate the significance of CTLp frequency assay in detection of residual Class I incompatibilities in matched unrelated pairs and in assessment of Class I compatibility in related pairs. For that it should be used in the final selection of bone marrow transplantation donors. (author)

    Clinical trials of various procedures, including bone marrow stimulation, mosaicplasty, and autologous chondrocyte implantation, have been explored to treat articular cartilage defects. However, all of them have some demerits. We focused on autologous culture-expanded bone marrow mesenchymal stem cells (BMSC), which can proliferate without losing their capacity for differentiation. First, we transplanted BMSC into the defective articular cartilage of rabbit and succeeded in regenerating osteochondral tissue. We then applied this transplantation in humans. Our previous reports showed that treatment with BMSC relieves the clinical symptoms of chondral defects in the knee and elbow joint. We investigated the efficacy of BMSC for osteoarthritic knee treated with high tibial osteotomy, by comparing 12 BMSC-transplanted patients with 12 cell-free patients. At 16-month follow-up, although the difference in clinical improvement between both groups was not significant, the arthroscopic and histological grading score was better in the cell-transplanted group. At the over 10-year follow-up, Hospital for Special Surgery knee scores improved to 76 and 73 in the BMSC-transplanted and cell-free groups, respectively, which were better than preoperative scores. Additionally, neither tumors nor infections were observed in all patients, and in the clinical study, we have never observed hypertrophy of repaired tissue, thereby guaranteeing the clinical safety of this therapy. Although we have never observed calcification above the tidemark in rabbit model and human histologically, the repair cartilage was not completely hyaline cartilage. To elucidate the optimum conditions for cell therapy, other stem cells, culture conditions, growth factors, and gene transfection methods should be explored.

    Purpose T-cell-replete HLA-haploidentical donor hematopoietic transplantation using post-transplant cyclophosphamide was originally described using bone marrow (BM). With increasing use of mobilized peripheral blood (PB), we compared transplant outcomes after PB and BM transplants. Patients and Methods A total of 681 patients with hematologic malignancy who underwent transplantation in the United States between 2009 and 2014 received BM (n = 481) or PB (n = 190) grafts. Cox regression models were built to examine differences in transplant outcomes by graft type, adjusting for patient, disease, and transplant characteristics. Results Hematopoietic recovery was similar after transplantation of BM and PB (28-day neutrophil recovery, 88% v 93%, P = .07; 100-day platelet recovery, 88% v 85%, P = .33). Risks of grade 2 to 4 acute (hazard ratio [HR], 0.45; P transplantation of BM compared with PB. There were no significant differences in overall survival by graft type (HR, 0.99; P = .98), with rates of 54% and 57% at 2 years after transplantation of BM and PB, respectively. There were no differences in nonrelapse mortality risks (HR, 0.92; P = .74) but relapse risks were higher after transplantation of BM (HR, 1.49; P = .009). Additional exploration confirmed that the higher relapse risks after transplantation of BM were limited to patients with leukemia (HR, 1.73; P = .002) and not lymphoma (HR, 0.87; P = .64). Conclusion PB and BM grafts are suitable for haploidentical transplantation with the post-transplant cyclophosphamide approach but with differing patterns of treatment failure. Although, to our knowledge, this is the most comprehensive comparison, these findings must be validated in a randomized prospective comparison with adequate follow-up.

  20. Myeloid regeneration after whole body irradiation, autologous bone marrow transplantation, and treatment with an anabolic steroid

    Ambrus, C.M.; Ambrus, J.L.

    1975-01-01

    Stumptail monkeys (Macaca speciosa) received lethal whole-body radiation. Autologous bone marrow injection resulted in survival of the majority of the animals. Treatment with Deca-Durabolin, an anabolic steroid, caused more rapid recovery of colony-forming cell numbers in the bone marrow than in control animals. Both the Deca-Durabolin-treated and control groups were given autologous bone marrow transplantation. Anabolic steroid effect on transplanted bone marrow colony-forming cells may explain the increased rate of leukopoietic regeneration in anabolic steroid-treated animals as compared to controls

    The Japan Marrow Donor Program (JMDP), established in 1991, has continued to grow in its capacity to facilitate unrelated bone marrow (BMT) and peripheral blood stem cell transplantation (PBSCT) for the past 25 years in Japan. The current donor pool is 463,465 (as of 31 December 2016) and 20,237 transplants were performed with the help of the Japanese Red Cross, government, and supporters. As JMDP introduced PBSCT in 2010, the vast majority of transplants are BMT. All donors are fully typed for HLA-A, B, C, and DR. The peak age of registered donors is around 40 years. The 8/8 HLA-matched donors are found in our registry for 96% of the patients and 54% of the patients receive a transplant. The median time between the initiation of donor search and the transplantation is approximately 122 days. The median interval between the initiation of donor search and identification of the first potential donor is 40 days. The most common diseases for which unrelated BMT/PBSCT is indicated are acute myelogenous leukemia (AML), acute lymphocytic leukemia (ALL), myelodysplastic syndrome (MDS), and malignant lymphoma. In recent years we have seen a marked increase in elderly patients who received BMT.

  2. Fractionated homogenous total-body irradiation prior to bone marrow transplantation

    1985-03-01

    At the University of Kiel, myeloid and acute lymphatic leukemia is treated since 1983 by total-body irradiation applied prior to bone marrow transplantation. Dose deviations in the midplane caused by the irregular surface and tissue inhomogeneities of the patient are reduced down to +-3.5% compared to the central ray, with the help of CT-based individual compensators. This method prevents above all an excessive dose to the lungs. The radiobiologic advantages of fractionated irradiation have been employed for all patients treated hitherto (n = 9). At present, a total body dose of 12 Gy in six fractions is applied within three days. There were no undesired acute radiogenic reactions except a mild acute mucositis found in all patients. Chronic side effects, especially in the lungs, were not demonstrated, too. However, the average follow-up time of 149 days has been rather short. One patient died from relapse of leukemia after a total dose of 10 Gy, another patient died because the transplanted bone marrow was rejected, and a third died from catheter sepsis. Six out of nine patients are in complete remission with a maximum index of Karnofsky. The limited experiences gained hitherto show that the homogeneous accelerated-fractionated total-body irradiation offers essential advantages compared to non-compensated single dose irradiation with respect to the prevention of undesired radiogenic effects in sound tissues and that its therapeutic efficacy is at least the same.

    1995-01-01

    Purpose: To define the maximum tolerated dose (MTD) of unshielded total body irradiation (TBI) delivered from dual 60 C sources at an exposure rate of 0.08 Gy/min and given in thrice daily fractions of 1.2 Gy in patients with advanced lymphoid malignancies. Methods and Materials: Forty-four patients with a median age of 28 (range 6-48) years were entered into a Phase I/II study. All patients received cyclophosphamide (CY), 120 mg/kg administered over 2 days before TBI. Marrow from human leukocyte antigen (HLA) identical siblings was infused following the last dose of TBI. An escalation-deescalation schema designed to not exceed an incidence of 25% of Grade 3-4 regimen-related toxicities (RRTs) was used. The first dose level tested was 13.2 Gy followed by 14.4 Gy. Results: None of the four patients at the dose level of 13.2 Gy developed Grade 3-4 RRT. Two of the first eight patients receiving 14.4 Gy developed Grade 3-4 RRT, establishing this as the MTD. An additional 32 patients were evaluated at the 14.4 Gy level to confirm these initial observations. Of 40 patients receiving 14.4 Gy, 13 (32.5%) developed Grade 3-4 RRTs; 46% in adults and 12% in children. The primary dose limiting toxicity was Grade 3-4 hepatic toxicity, which occurred in 12.5% of patients. Noninfectious Grade 3-4 interstitial pneumonia syndrome occurred in 5% of patients. The actuarial probabilities of event-free survival, relapse, and nonrelapse mortality at 2 years were 0.10, 0.81, and 0.47, respectively, for patients who received 14.4 Gy of TBI. Conclusions: The outcome for patients receiving 14.4 Gy of TBI was not different from previous studies of other CY and TBI regimens in patients with advanced lymphoid malignancies. These data showed that the incidence of Grade 3-4 RRTs in adults was greater than the 25% maximum set as the goal of this study, suggesting that 13.2 Gy is a more appropriate dose of TBI for adults, while 14.4 Gy is an appropriate dose for children

    Cutaneous squamous cell carcinomas arise as secondary cancers in hematopoietic stem cell transplant survivors. They have been documented primarily in Western cohorts and relatively little is known about their occurrence in Asian hematopoietic stem cell transplant recipients, with no reports of squamous cell carcinomas with high-risk features in Asian patients. We describe a case of a cutaneous squamous cell carcinoma with high-risk features on the scalp of a Japanese bone marrow transplant recipient approximately 6.5 years post-transplant, who was on long-term voriconazole. The history of a photodistributed erythema followed by the appearance of multiple actinic keratoses and solar lentigines, together with the rarity of cutaneous squamous cell carcinomas in Asian hematopoietic stem cell transplant cohorts revealed in our literature review, suggest that voriconazole use contributed to the development of high-risk squamous cell carcinoma in our patient. © 2017 Japanese Dermatological Association.

    We developed a successful bone marrow transplant protocol in MHC-inbred miniature swine (MS). Three groups of MS were studied: irradiation controls, autologous bone marrow transplants and SLA matched bone marrow allografts. One day prior to irradiation, all animals underwent Hickman catheter placement via the external jugular vein. Bone marrow was harvested by direct mechanical removal of marrow from four long bones in Groups 2 and 3 one day prior to irradiation. All animals received 900 rads of midline body radiation from a Cobalt-60 source, were treated 1 g of cephalothin IV bid from day 1 to 14, 20 mg of genetamicin IV bid, from day 4 through 14 and 250 to 350 ml of fresh, irradiated whole blood from blood group identical donors on days 7, 11 and 14. Bone marrow was filtered, washed, stored overnight at 4 C and reinfused one to six hr after irradiation. Engraftment was defined by return of the peripheral WBC to 1000/mm 3 . All six animals in Group 1 died of aplasia between days 7 and 12. Marrow engrafted in eight of 12 animals in Group 2 and 7 of 10 animals in Group 3. This model provides a means to study the biological characteristics of bone marrow transplantation in immunologically well characterized large animals and should prove useful as a model for bone marrow transplants in man

    Bone marrow was recently proposed as an alternative and potentially immune-privileged site for pancreatic islet transplantation. The aim of the present study was to assess the survival and rejection mechanisms of free and encapsulated xenogeneic islets transplanted into the medullary cavity of the femur, or under the kidney capsule of streptozotocin-induced diabetic C57BL/6 mice. The median survival of free rat islets transplanted into the bone marrow or under the kidney capsule was 9 and 14 days, respectively, whereas that of free human islets was shorter, 7 days (bone marrow) and 10 days (kidney capsule). Infiltrating CD8+ T cells and redistributed CD4+ T cells, and macrophages were detected around the transplanted islets in bone sections. Recipient mouse splenocytes proliferated in response to donor rat stimulator cells. One month after transplantation under both kidney capsule or into bone marrow, encapsulated rat islets had induced a similar degree of fibrotic reaction and still contained insulin positive cells. In conclusion, we successfully established a small animal model for xenogeneic islet transplantation into the bone marrow. The rejection of xenogeneic islets was associated with local and systemic T cell responses and macrophage recruitment. Although there was no evidence for immune-privilege, the bone marrow may represent a feasible site for encapsulated xenogeneic islet transplantation. PMID:24625569

    1991-10-01

    A concentrate of mononuclear bone marrow cells is often desired for ex vivo treatment with pharmacologic agents, monoclonal antibodies, cytokines, and other agents prior to transplantation. A method has been developed for automated separation of mononuclear cells from large volumes of harvested bone marrow. A programmable instrument originally designed for clinical ex vivo cell separation and the plasma-pheresis of patients and blood donors was adapted to permit rapid preparation, in a closed sterile system, of a bone marrow product enriched with mononuclear cells. A mean (+/- SEM) of 53 +/- 30 percent of the original mononuclear cells was recovered in a volume of 125 +/- 42 mL containing 82 +/- 12 percent mononuclear cells. This technique removed 95 +/- 9 percent of the red cells in the original marrow. No density gradient materials or sedimenting agents were employed in this process. Of 36 marrows processed by this technique, 19 autologous (6 of which were purged with 4-hydroperoxycyclophosphamide) and 7 allogeneic marrows have been transplanted, with all evaluable patients achieving a neutrophil count of 0.5 x 10(9) per L in a mean (+/- SEM) of 21 +/- 6 days.

  9. Indication of total body irradiation in adult allogeneic bone marrow transplantation

    1992-10-01

    Indication of total body irradiation (TBI) in adult allogeneic bone marrow transplantation was discussed in comparison with non-TBI method of busulfan and cyclophosphamide (BU+CY). Each method has unique advantages and disadvantages. Concerning adverse effects of interstitial pneumonia, liver dysfunction and so on, there are no significant differences in both methods. TBI method should be preferably indicated for lymphatic leukemias and leukemias involving central nervous systems. It is important to clarify what kinds of combination regimen depending on the type and the stage of disease are most suitable for the longer survival of patients with leukemia or aplastic anemia by multicentric randomized study.

  11. Total lymphoid irradiation and total body irradiation for allogeneic bone marrow transplantation in aplastic anemia

    Between April 1980 and June 1989, 15 patients with severe aplastic anemia (SAA) were treated at Hyogo College of Medicine with bone marrow transplantation (BMT) after preparation consisting of cyclophosphamide (CY) and total lymphoid irradiation (TLI) or total body irradiation (TBI) for the purpose of reducing the incidence of graft rejection. All patients had initial evidence of engraftment after the first transplantation except for one patient who died of heart failure due to CY on the third day after transplantation and could not be evaluated for engraftment. Rejection later occurred in four of these 14 patients, who then underwent successful regrafting. One of these four patients, who was conditioned with CY alone at the first grafting, underwent successful regrafting after a conditioning regimen of CY and TBI. In the other three patients, irradiation was performed twice as the conditioning regimen. Thus, 14 of 15 patients underwent successful BMT and are alive with restored hematopoietic function. From the above results, the combination of TLI or TBI and CY was considered to be very useful as a conditioning regimen for BMT in patients with SAA. (author).

  12. Transplantation tolerance in primates following total lymphoid irradiation and allogeneic bone marrow injection. II. Renal allographs

    1980-01-01

    A modified regimen of fractionated total lymphoid irradiation and allogeneic bone marrow (BM) injection in chacma baboons produced transplantation tolerance for allografted kidneys from the BM donors, and substantial chimerism without evidence of graft-versus-host disease. Increasing the dose of nucleated BM cells injected 4-fold over that used in liver transplantation resulted consistently in normal graft function in the early weeks after transplantation. Bone marrow injection and challenge with renal allografts could be delayed for at least 3 weeks after completion of irradiation. If it can be shown that this period can be extended even further, the protocols will be relevant to the circumstances of clinical cadaveric renal transplantation

  13. Propofol promotes spinal cord injury repair by bone marrow mesenchymal stem cell transplantation

    Propofol is a neuroprotective anesthetic. Whether propofol can promote spinal cord injury repair by bone marrow mesenchymal stem cells remains poorly understood. We used rats to investigate spinal cord injury repair using bone marrow mesenchymal stem cell transplantation combined with propofol administration via the tail vein. Rat spinal cord injury was clearly alleviated; a large number of newborn non-myelinated and myelinated nerve fibers appeared in the spinal cord, the numbers of CM-Dil-labeled bone marrow mesenchymal stem cells and fluorogold-labeled nerve fibers were increased and hindlimb motor function of spinal cord-injured rats was markedly improved. These improvements were more prominent in rats subjected to bone marrow mesenchymal cell transplantation combined with propofol administration than in rats receiving monotherapy. These results indicate that propofol can enhance the therapeutic effects of bone marrow mesenchymal stem cell transplantation on spinal cord injury in rats. PMID:26487860

    Acute myeloid leukaemia (AML) with 17p abnormalities (abn(17p)) carries a very poor prognosis due to high refractoriness to conventional chemotherapy, and allogeneic stem cell transplantation (allo-SCT) appears as the only potential curative option. To address outcomes after allo-SCT in patients with abn(17p), we retrospectively analysed de novo or secondary AML undergoing SCT between 2000 and 2013 from the EBMT registry. One hundred thirty-nine patients with confirmed abn(17p) have been selected. At the time of transplant, one hundred twenty-five were in first remission (CR1). Median age was 54 years old. Abn(17p) was associated with a monosomal karyotype in 83% of patients, complex karyotype in 91%, monosomy 5 or 5q deletion (-5/5q-) in 55%, monosomy 7 (-7) in 39% and both -5/5q and -7 in 27%. Seventy-three patients (59%) had a reduced-intensity conditioning regimen. The 2-year overall survival (OS) and leukaemia-free survival (LFS) were 28 and 24%, respectively. The 2-year non-relapse mortality (NRM) was 15%, and 2-year relapse incidence (RI) was 61%. The cumulative incidence of grade II to IV acute graft-versus-host disease (GvHD) was 24% and that of chronic GvHD was 21%. In multivariate analysis, the presence of a -5/5q- in addition to abn(17p) was significantly and independently associated with worse OS, LFS and higher RI. Age and donor types did not correlate with outcome. Conditioning intensity was not statistically associated with OS, LFS and NRM when adjusted for patients' age. In contrast to the dismal prognosis reported for AML patients harbouring abn(17p) undergoing conventional chemotherapy, allogeneic SCT provides responses in about 25% of those patients transplanted in CR1.

    2003-01-01

    Full Text Available The feasibility of allogeneic bone marrow transplantation (alloBMT in a developing country has not yet been demonstrated. Many adverse factors including social and economic limitations may reduce the overall results of this complex and expensive procedure. Our objective was to characterize the most important clinical, social and economic features of candidates for transplantation and their potential donors as well as the influence of these factors on overall survival in a retrospective and exploratory analysis at a university hospital. From July 1993 to July 2001, candidates for BMT were referred to the Bone Marrow Transplantation Unit by Hematology and Oncology Centers from several regions of Brazil. A total of 1138 patients were referred to us as candidates for alloBMT. Median age was 25 years (range: 2 months-60 years, 684 (60.1% were males and 454 (39.9% were females. The clinical indications were severe aplastic anemia and hematological malignancies. From the total of 1138 patients, 923 had HLA-typing; 497/923 (53.8% candidates had full match donors; 352/1138 (30.8% were eligible for alloBMT. Only 235 of 352 (66.7% were transplanted. Schooling was 1st to 8th grade for 123/235 (52.3%; monthly family income ranged from US$60 (7% to more than US$400 (36%. Overall survival for patients with chronic myeloid leukemia, severe aplastic anemia and acute myeloid leukemia was 58, 60 and 30%, respectively. Thus, overall survival rates for the most frequent hematological diseases were similar to those reported in the International Registry, except for acute myeloid leukemia. This descriptive and exploratory analysis suggests the feasibility of alloBMT in a developing country like Brazil.

  18. The production of IL-1, IL-3, CSA by bone marrow nuclears during bone marrow haemopoiesis after lethal irradiation and syngenic bone marrow transplantation

    The production of haemopoietic factors (IL-1, IL-3, CSA) by adherent and unadherent cells of lethally irradiate CBA mice bone marrow and after syngenic myelokaryocyte transplantation was studied. Radioresistant myelokaryocytes capable to produce haemopoetic factors IL-1, CSA as early as 24 hr after irradiation were found in adherent cell fraction. The synthesis of humoral factors (IL-3, CSA) by unadherent bone marrow elements was realised in a late of experiment (3-6 days) that was connected with forming of functionally valuable cell forms from transplanted or viable stem cells

  19. Fungal infections in marrow transplant recipients under antifungal prophylaxis with fluconazole

    Oliveira J.S.R.

    2002-01-01

    Full Text Available Fungal infection is one of the most important causes of morbidity and mortality in bone marrow transplant (BMT recipients. The growing incidence of these infections is related to several factors including prolonged granulocytopenia, use of broad-spectrum antibiotics, conditioning regimens, and use of immunosuppression to avoid graft-versus-host disease (GvHD. In the present series, we report five cases of invasive mold infections documented among 64 BMT recipients undergoing fluconazole antifungal prophylaxis: 1 A strain of Scedosporium prolificans was isolated from a skin lesion that developed on day +72 after BMT in a chronic myeloid leukemic patient. 2 Invasive pulmonary aspergillosis (Aspergillus fumigatus was diagnosed on day +29 in a patient with a long period of hospitalization before being transplanted for severe aplastic anemia. 3 A tumoral lung lesion due to Rhizopus arrhizus (zygomycosis was observed in a transplanted patient who presented severe chronic GvHD. 4 A tumoral lesion due to Aspergillus spp involving the 7th, 8th and 9th right ribs and local soft tissue was diagnosed in a BMT patient on day +110. 5 A patient with a history of Ph1-positive acute lymphocytic leukemia exhibited a cerebral lesion on day +477 after receiving a BMT during an episode of severe chronic GvHD. At that time, blood and spinal fluid cultures yielded Fusarium sp. Opportunistic infections due to fungi other than Candida spp are becoming a major problem among BMT patients receiving systemic antifungal prophylaxis with fluconazole.

  20. Pulmonary function changes in long-term survivors of bone marrow transplantation

    Gore, Elizabeth M.; Lawton, Colleen A.; Ash, Robert C.; Lipchik, Randolph J.

    1996-01-01

    Purpose: This study was undertaken to evaluate long-term pulmonary function changes in patients undergoing bone marrow transplantation (BMT), to assess their clinical significance, and to identify factors influencing these changes. Methods and Materials: Pulmonary function tests (PFT) were evaluated before and after BMT in 111 adult patients undergoing BMT between 1985 and 1991. Forced expiratory volume at 1 s (FEV 1 ), forced vital capacity (FVC), diffusing capacity (DLCO), and total lung capacity (TLC) were evaluated. One hundred and three patients (92.8%) received total body irradiation (TBI) to a total dose of 14 Gy in nine equal fractions. The lung dose was restricted to 1 , FVC, and TLC were lower than pre transplant values (p 1 did not fall significantly in patients without acute or chronic GVHD and recovered earlier than in patients without post transplant pulmonary infection. Recovery of FVC, TLC, and DLCO was also delayed in patients with acute and chronic GVHD and post transplant pulmonary infection. Multiple regression analysis revealed an association between a higher radiation dose to the lungs, and decreased FVC at 2 years (p = 0.01). Progressive obstructive pulmonary disease was not observed. Conclusions: An initial decline in PFTs with subsequent recovery was observed. Factors associated with delayed recovery and incomplete recovery of PFTs were GVHD, post transplant pulmonary infection, and higher radiation dose to the lungs. The conditioning regimen used at Medical College of Wisconsin, including relatively high TBI doses with partial transmission pulmonary shielding, appears to be well tolerated by the lungs in long-term survivors. No progressive decline in PFTs or symptomatic decline in pulmonary function was observed during the time interval studied

    bone re-absorption also leads to macrocephaly, frontal bossing, hypertelorism, exophthalmos, increased intracranial pressure, retarded tooth eruption, retarded linear growth and psychomotor delay. Death occurs within the first years of life. The only curative therapy is allogeneic bone marrow transplantation with a HLA-identical donor, which restores hematopoiesis, monocyte-macrophage function and bone recovery, but there is no sensorial deficit restoration once present. The authors report two cases of allogeneic bone marrow transplant for infantile malignant osteopetrosis. The first child, on day 1260 after bone marrow transplantation (BMT, showed radiologic bone recovery and no progression of neurological deficits with a bone biopsy showing no signs of osteopetrosis. The second child showed signs of bone re-absorption and no progression of neurological deficits on day 700. The authors emphasize the importance of early diagnosis of osteopetrosis and the necessity of bone marrow transplantation before neurological deficits have begun.

    The regenerative potential of bone marrow-derived mononuclear cells (MNCs) and CD133+ stem cells in the heart varies in terms of their pro-angiogenic effects. This phase II/III, multicenter and double-blind trial is designed to compare the functional effects of intramyocardial autologous transplantation of both cell types and placebo in patients with recent myocardial infarction (RMI) post-coronary artery bypass graft. This was a phase II/III, randomized, double-blind, placebo-controlled trial COMPARE CPM-RMI (CD133, Placebo, MNCs - recent myocardial infarction) conducted in accordance with the Declaration of Helsinki that assessed the safety and efficacy of CD133 and MNCs compared to placebo in patients with RMI. We randomly assigned 77 eligible RMI patients selected from 5 hospitals to receive CD133+ cells, MNC, or a placebo. Patients underwent gated single photon emission computed tomography assessments at 6 and 18 months post-intramyocardial transplantation. We tested the normally distributed efficacy outcomes with a mixed analysis of variance model that used the entire data set of baseline and between-group comparisons as well as within subject (time) and group×time interaction terms. There were no related serious adverse events reported. The intramyocardial transplantation of both cell types increased left ventricular ejection fraction by 9% [95% confidence intervals (CI): 2.14% to 15.78%, P=0.01] and improved decreased systolic wall thickening by -3.7 (95% CI: -7.07 to -0.42, P=0.03). The CD133 group showed significantly decreased non-viable segments by 75% (P=0.001) compared to the placebo and 60% (P=0.01) compared to the MNC group. We observed this improvement at both the 6- and 18-month time points. Intramyocardial injections of CD133+ cells or MNCs appeared to be safe and efficient with superiority of CD133+ cells for patients with RMI. Although the sample size precluded a definitive statement about clinical outcomes, these results have provided the

  4. Fatal veno-occlusive disease of the liver after chemotherapy, whole-body irradiation and bone marrow transplantation for refractory acute leukaemia

    Jacobs, P.; Miller, J.L.; Uys, C.J.; Dietrich, B.E.

    1979-01-01

    Rapid onset of liver failure with fatal outcome occured in a young woman after successful bone marrow transplantation undertaken for refractory acute leukaemia. Centrilobular necrosis was demonstrated at autopsy and was attributed to prior cytotoxic chemotherapy, possibly potentiated by the total-body irradiation that was used in preparation for the transplant. This association between liver damage and prolonged drug therapy, coupled with the short median survival currently achieved within these chemotherapy regimens, has initiated an evaluation of bone marrow transplantation in patients with leukaemia during the first complete remission, rather than at a later stage when cumulative drug toxicity to the liver may have taken place

    Sterile ice cream and frozen yogurt were offered to immunosuppressed patients recovering from bone marrow transplantation. To obtain sterile products, two of the dairy desserts (prepackaged ice cream and frozen yogurt bars) were exposed to 40 kGy of cobalt 60 irradiation. Four different flavors of ice cream were aseptically prepared under a laminar airflow hood using commercially sterilized ingredients. A commercially sterile, frozen milk-based drink on the low-microbial menu served as the control. Ratings of the seven products by 17 patients indicated that a frozen vanilla milk-based drink and aseptically prepared chocolate ice cream were highly acceptable to recovering immunosuppressed patients who have difficulty eating most foods. However, the seven desserts received higher ratings from a sensory panel of healthy individuals than from the patient panel, confirming that new foods for the low-microbial diet should be ''market-tested'' by the targeted patient population before inclusion in the menu

  7. Targeting the bone marrow: applications in stem cell transplantation

    Orchard, K.; Cooper, M.

    2004-01-01

    Therapeutic doses of radiation cab be selectively directed to the bone marrow either directly using vectors that bind to myeloid and/or lymphoid specific antigens or indirectly by targeting bone matrix. The combination of an accessible target tissue and relatively radiation sensitive malignant cells favours the use of targeted radiotherapy in the treatment of haematopoietic malignancies. Dose escalation of targeted radiation can increase tumour cell destruction and has led to the use of myelosuppressive and possibly myeloablative doses of targeted radiation. A natural development has been the use of targeted radiation in conditioning prior to haematopoietic stem cell transplantation (HSCT). Several groups are actively exploring the use of targeted radiotherapy in the context of HSCT as treatment for haematological malignancies. Although no randomised trials using targeted radiotherapy in HSCT have been published, phase I and II trials have shown very encouraging results stimulating further clinical research in this field. After more than a decade of translational research the optimal combination of therapeutic radioisotope and vector has not been determined. This review summarises the clinical experience of targeted radiotherapy in HSCT and discusses the problems that still need to be solved to maximise the potential of this new treatment modality in HSCT

  8. Administration of RANKL boosts thymic regeneration upon bone marrow transplantation.

    Lopes, Noella; Vachon, Hortense; Marie, Julien; Irla, Magali

    2017-06-01

    Cytoablative treatments lead to severe damages on thymic epithelial cells (TECs), which result in delayed de novo thymopoiesis and a prolonged period of T-cell immunodeficiency. Understanding the mechanisms that govern thymic regeneration is of paramount interest for the recovery of a functional immune system notably after bone marrow transplantation (BMT). Here, we show that RANK ligand (RANKL) is upregulated in CD4 + thymocytes and lymphoid tissue inducer (LTi) cells during the early phase of thymic regeneration. Importantly, whereas RANKL neutralization alters TEC recovery after irradiation, ex vivo RANKL administration during BMT boosts the regeneration of TEC subsets including thymic epithelial progenitor-enriched cells, thymus homing of lymphoid progenitors, and de novo thymopoiesis. RANKL increases specifically in LTi cells, lymphotoxin α, which is critical for thymic regeneration. RANKL treatment, dependent on lymphotoxin α, is beneficial upon BMT in young and aged individuals. This study thus indicates that RANKL may be clinically useful to improve T-cell function recovery after BMT by controlling multiple facets of thymic regeneration. © 2017 The Authors.

    Five-year neurodevelopmental studies of two infants with acute leukemia are presented. Both patients underwent bone marrow transplantation (BMT) after conditioning with cyclophosphamide and total body irradiation (TBI). Neither patient was treated with intrathecal chemotherapy. Their outcome is remarkable for normal development of intelligence, language, perception, and motor coordination. These results suggest that TBI and BMT should be considered in future therapeutic studies of infants with acute leukemia, who are at great risk for failure of conventional therapy

    The study of the dog bone marrow preserved at -196 deg C during 6-12 years has shown that in the body of lethally irradiated animals (8Gy), due to the antigenic difference in the tissues of the donor and the irradiated recipients, the cells of cryopreserved allogeneic bone marrow were differentiated by the lymphoid type similar to that observed in transplantation of freshly prepared myelocaryocytes. However, their proliferative activity in the period of active lymphocyte transformation was quantitatively less manifest than in freshly transplanted cells. The results of the study evidence that the bone marrow cells cryopreserved during 6-12 years retain their functional activity

    1992-01-01

    The effect of lethal irradiation and transplantation of syngenic bone marrow on the morphofunctional state of hypophysis at various stages of the posttransplantation period has been studied for 3 months using 100 linear male mice of 1 F 1 (CBAXC 57 B) line. The experiments conducted have shown that bone marrow transplantation reduces the intensity of the negative effect of irradiation on hypophysis and facililitates normalization of its histological structure. There was a correlation between changes in the number of secretory cells in the anterior lobe of the hypophysis and the level of corticosterone in irradiated and bone-marrow-protected animals

    Purpose. Reveal features migration and distribution of syngeneic bone marrow cells (BMC) and subpopulations (MSC) after transplantation into the recipient carrier B16 melanoma bodies. Methods. We used mouse male and female C57BL/6 mice. Induction of Tumor Growth: B16 melanoma cells implanted subcutaneously into right hind paw of female C57BL/6 mice at a dose of 2.5 x 105 cells / mouse. migration study in vivo distribution and BMC and MSC was performed using genetic markers - Y-chromosome specific sequence line male C57Bl/6 syngeneic intravenous transplantation in females using the polymerase chain reaction (PCR) in real time on Authorized Termal Cycler - Light Cycler 480 II / 96 (Roche). Introduction suspension of unseparated bone marrow cells, mesenchymal stem cells from donor to recipient male mice (syngeneic recipient female C57BL/6), followed by isolation of recipients of organs was performed at regular intervals, then of organ recipients isolated DNA. Results. It was shown that bone marrow cells positive for Y-chromosome in migrate lymphoid (lymph nodes, spleen, bone marrow) or in non-lymphoid organs (liver, heart, brain, skin) syngeneic recipients. In addition to the migration of cells from the bone marrow to other organs, there is a way back migration of cells from the circulation to the bone marrow. B16 melanoma stimulates the migration of transplanted MSCs and BMC in bone marrow. It is found that tumor growth enhanced migration of transplanted bone marrow cells, including populations of MSCs in the bone marrow. In the early stages of tumor formation MSC migration activity higher than the BMC. In the later stages of tumor formation undivided population of bone marrow cells migrate to the intense swelling compared with a population of MSCs. Conclusion. The possibility of using bone marrow MSCs for targeted therapy of tumor diseases, because migration of MSCs in tumor tissue can be used to effectively deliver anticancer drugs.

    In Essen 121 bone marrow transplantations were carried out. The indications were severe aplastic anemia, acute leukemia in relapse, acute leukemia in remission or chronic myeloid leukemia. The conditioning regimen consisted of cyclophosphamide or the combination of cyclophosphamide and total body irradiation. All patients were treated under strict gnotobiotic care. To mitigate the risk of CMV infections intravenous CMV-hyperimmunoglobulin and CMV-negative blood products have been applied routinely since two years. MTX was used as prophylaxis against GVH-disease. In case of severe aplastic anemia 13 patients (72%) are still alive with a median observation time of 24 months. In the prognostically unfavourable group of acute leukemia in relapse only one patient showed long term survival. In this patient leukemic relapse occurred six years after transplantation. The survival rate of AML patients grafted during the first remission is 55% with a median observation time of 40 months. For patients grafted in the first consecutive remission of ALL the survival rate is 42% with a maximal observation time of 29 months. Out of 37 patients grafted because of CML, eight were in an advanced stage of the disease. 13 patients are still alive, the maximal observation time is 37 months. The overall incidence of GVHD in patients at risk was 28% in aplastic anemia, 26% in AML, 9% in ALL and 63% in CML. In aplastic anemia no patient developed an interstitial pneumonia. In leukemia the risk of fatal interstitial pneumonia was 34%.

    Between July 1987 and December 1992, we treated 22 patients with chromic myelogenous leukemia; 14 in the chronic phase and 8 with more advanced disease. All were received with allogeneic bone marrow transplantation from HLA-identical sibling donors after a total body irradiation (TBI) cyclophosphamide conditioning regimen. Patients were non-randomly assigned to either 1200 cGy/6 fractions/3 days (6 patients) or 1320 cGy/8 fractions/4 days (16 patients) by dose of TBI. Of the 22 patients, 8 were prepared with cyclophosphamide alone, 14 were conditioned with additional adriamycin or daunorubicin. To prevent graft versus host disease, cyclosporine was given either alone or in conjunction with methotrexate. The actuarial survival and leukemic-free survival at four years were 58.5% and 41.2%, respectively, and the relapse rate was 36% among 22 patients. There was a statistically significant difference in survival between the patients in chronic phase and more advanced phase (76% vs 33%, p=0.05). The relapse rate of patients receiving splenectomy was higher than that of patients receiving splenic irradiation (50% vs 0%, p=0.04). We conclude that the probability of cure is highest if transplantation is performed while the patient remains in the chronic phase

    Background: Malignant infantile osteopetrosis (MIOP) is a sclerosing bone disease caused by absence or defective function of osteoclasts. Since these are of haemopoietic origin, the disease can be cured by allogeneic stem-cell transplantation, but there are no detailed studies of radiological follow-up of these procedures. Objective: To investigate the radiological findings at presentation and follow-up in children undergoing bone marrow transplantation (BMT) for MIOP. Materials and methods: Examination of the records and imaging studies of nine paediatric patients undergoing BMT for MIOP during 1988-2000. Results: Presentation findings included characteristic features such as fractures, subperiosteal new bone formation and rachitic appearances. Five children engrafted successfully, allowing assessment of the nature and speed of resolution of radiological features after transplantation. Conclusions: Radiological improvement was apparent within 2 months of successful engraftment with almost complete resolution of abnormalities after 1 year. Studies in two children who are, respectively, 58 and 83 months post-transplant show complete resolution of all bone changes. (orig.)

  18. Factors modifying the toxicity of total body irradiation (TBI) with bone marrow transplant

    Fish, B.L.; Moulder, J.E.

    1987-01-01

    In defined-flora, barrier-maintained rats, radiation nephritis is the principle late toxicity seen after single dose, high dose rate TBI with bone marrow transplant. Shielding the kidneys eliminates this late toxicity. If rats are exposed to a conventional microbiological environment during and after TBI and bone marrow transplant, the principle late toxicity is pneumonitis. Low dose rate TBI gives similar renal toxicity but at doses twice as large. Clinically, TBI and bone marrow transplant is preceded by intensive drug treatment, typically with cyclophosphamide (Cytoxan) and cytosine arabinoside (ara-C). Pretreatment with a standard cytoxan/ara-C regimen, has no effect on the gastrointestinal toxicity of TBI, but results in a decrease in marrow toxicity. Late renal toxicity still occurs when bone marrow transplants are given, but it is to early to determine whether drug treatment has affected late renal tolerance. Experiments are also underway to determine the effects of fractionated TBI (3, 6 and 9 fractions in 60 hours) on acute tolerance and on late tolerance after bone marrow transplantation

    We report the outcome of 50 consecutive patients with CR1 acute leukemia (AML = 22; ALL = 28) treated with autologous BMT, after cyclophosphamide and TBI, followed with a sequential high dose rIL2 regimen. rIL-2 (RU 49637 from Roussel-Uclaf, Romainville, France) was started after hematological reconstitution an average of 72 +/- 22 days post transplant. The schedule consisted of a continuous infusion over 5 cycles (Cycle 1: 5 days starting on day 1; cycle 2-5: 2 days starting on day 15, 29, 43 and 57). Patients were treated at 4 different dosages (12 (N = 40), 16 (N = 3), 20 (N = 2), 24 (N = 5) x 10(6) IU/m2/day). Toxicities were mainly related to capillary leak syndrome and thrombocytopenia. Patients received an average of 122 +/- 49 10(6) IU/m2. Two patients with AML died from toxicity. rIL-2 infusion was associated with very a high level of immune stimu-lation of both T-cells (P < 0.05) and natural killer (NK) cells (P < 0.05) and associated cytolytic functions (P < 0.05). With a minimal and median follow-up of 21 and 46 months, 3 year leukemia free survival is 41 +/- 6% overall, 39 +/- 10% and 43 +/- 8% for AML and ALL respectively. Relapse probabilities at 3 years are 59 +/- 11% for AML and 57 +/- 8% for ALL. We conclude that this short infusion of rIL-2 over 2 months, resulting in an increased immune stimulation, is not associated with a better leukemic control for patients with acute leukemia transplanted early after reaching first complete remission.

  20. The separation of a mixture of bone marrow stem cells from tumor cells: an essential step for autologous bone marrow transplantation

    KHT tumor cells were mixed with mouse bone marrow to simulate a sample of bone marrow containing metastatic tumor cells. This mixture was separated into a bone marrow fraction and a tumor cell fraction by centrifugal elutriation. Elutriation did not change the transplantability of the bone marrow stem cells as measured by a spleen colony assay and an in vitro erythroid burst forming unit assay. The tumorogenicity of the KHT cells was similarly unaffected by elutriation. The data showed that bone marrow cells could be purified to less than 1 tumor cell in more than 10 6 bone marrow cells. Therefore, purification of bone marrow removed prior to lethal radiation-drug combined therapy for subsequent autologous transplantation appears to be feasible using modifications of this method if similar physical differences between human metastatic tumor cells and human bone marrow cells exist. This possibility is presently being explored

    Full text: Allogenic bone-marrow grafting in 24 human leukaemic subjects is described. The graft failed in 7 cases and took in 17 cases. In the latter group, all 17 cases were complicated by the secondary syndrome which was-fatal in 13 cases and controlled in 4 cases. The immunogenetic and immunological factors determining the establishment and evolution of haematological radiochimeras in man are discussed. The choice of donor is fundamental. Three tests are effective in donor selection, the indirect histocompatibility test, the leucocyte antigen test and the reaction of donor and recipient leucocytes in the dermis of an irradiated hamster. When marrow from several donors is transfused, the recipient spontaneously selects the genetically nearest. It seems likely there is more chance of finding a suitable donor among genetically related subjects than among those who are unrelated. The frequency of graft take seems slightly lower in recipients who have previously received blood transfusions. Total bone-marrow graft is associated with specific tolerance towards donor tissues. This is paralleled by the production in the chimera of immunoglobulins produced by the graft. The secondary syndrome seems, as in animals, to be related essentially to the graft-versus-host reaction. It is convenient to distinguish among its various manifestations, on the one hand, those lesions which are readily controlled such as hepatitis or erythrodermia associated with infiltration and proliferation of immunologically competent cells from the graft and, on the other hand, immune insufficiency with regard to micro-organisms, especially viruses and Candida albicans. This latter group, the mechanism of which is complex, still eludes attempts at preventive and curative control. The use of multiple donors and the administration of cortisone during marrow transfusion and A-methopterin and/or cyclophosphamide in the days following transfusions; seem to have reduced the severity of the secondary

    About 50 000 bone-marrow transplantations (BMT) are performed annually at the present stage in numerous clinical centers all over the world. The Bulgarian experience in total-body irradiation (TBI) with following BMT is rather scarce. The routine TBI procedures in the oncological practice in the country date back just to 2001. The aim of the present publication is to describe the Bulgarian experience and the first impressions from the clinical tolerance of the total-body irradiation (TBI) with subsequent allogeneic peripheral stem cell transplantation (PSCT). Patient characteristics are presented in detail, including their distribution with respect to sex, age, primary diagnose, recurrence number till BMT, patient status during BMT performance (clinical hematological remission or relapse), as well as the basic parameters of the conditioning regime including TBI with subsequent allogeneic PSCT. The position of the patient and the applied radiotherapeutic equipment are described as well as the TBI schemes, respectively 5 fractions of 2 Gy per day for two patients and 3-day irradiation with 6 fractions (two fractions with a 6-hour interval between them) for the rest of the patients. The total dose (TD) of 10 Gy is realized for all patients. The clinical tolerance of 7 patients subjected to TBI and allogeneic PSCT is discussed. All patients were tolerable to the TBI treatment and had no serious problems. The radiotherapy was interrupted only in the case of the first two patients due to slight gastro-intestinal reactions. The first days of radiation were accompanied with a light degree of headache, nausea and vomiting, which were successfully overcome by granisetron. Diarrhea syndrome and mucositis to the II-III degree were developed subsequently without parotitis development. On the days 0 and +1 of the clinical protocol transplantation was realized of non- T-cell-depleted grafts (in 5 patients) and T-cell-depleted grafts (in 2 patients), which had no serious

    The important insights gained over the past years in diagnosis and treatment of invasive adenoviral infections provide new paradigms for the monitoring and clinical management of these life-threatening complications. A meeting was held to discuss and subsequently disseminate the current advances in our understanding of the aetiology/pathogenesis and future treatment options facilitating effective control or prevention of adenovirus-related diseases in the allogeneic haematopoietic stem cell transplant setting. Invited experts in the field discussed recent progress with leading members of the Infectious Diseases Working Party of the European Society of Blood and Marrow Transplantation at the "State-of-the-art" Meeting in Poznan, Poland, in October 2017. In this review article, the panel of experts presents a concise summary of the current evidence based on published data from the last 15 years and on recent achievements resulting from real-life practice. The present position statement reflects an expert opinion on current approaches to clinical management of adenovirus infections in patients undergoing allogeneic haematopoietic stem cell transplant and provides graded recommendations of the panel for diagnostic approaches and preemptive therapy reflecting the present state of knowledge.

    From january 1984 to may 1986, 31 patients, 15 ANLL, 8 ALL (in remission status) and 8 NHL (6 in remission, 2 in relapse) have been treated with chemo-radiotherapy (cyclophosphamide 60 mg/kg x 2 days + total body irradiation (TBI): 10 Gy/3 fr./3 days with 4 Gy boost testicular dose in ALL) and autologous bone marrow transplantation (BMT). Seventeen patients are alive, 16 in remission: 9 (60%) ANLL, 2 (25%) ALL, 5 (62%) NHL (median 8+ months, follow up 1+ /29+); 2 patients presented interstitial pneumonitis (6.45%). In this series, very good results have been achieved in ANLL, where no relapse was noted, encouraging achievements in NHL, with 4/8 relapse. Advantages and disadvanteges of autologus relative to allogenic BMT, and of conditioning regimen with or without TBI are discussed.

    In this study, we investigated the impact of recombinant interleukin-2 (rIL-2) after high dose chemotherapy and autologous bone marrow transplantation (ABMT) in 25 patients with refractory or relapsed Hodgkin's disease (HD) (11 patients) and non Hodgkin's lymphoma (NHL) (14 patients). 48% of patients had resistant disease, 84% achieved complete remission after ABMT. rIL-2 was started at a median of 54 days post-transplant and consisted of a first cycle of 5 days followed by 4 cycles of 2 days every other week. Patients received a mean of 160 x 10(6) IU/m2 rIL-2 and hematological toxicity was moderate and transient. None of the 5 evaluable patients with measurable disease responded to rIL-2. After a 5 year median follow-up, the probability of survival and DFS is 72% (HD: 73% and NHL: 70%, p = NS) and 45% (HD: 36% and NHL: 48%, p = NS) respectively. These somewhat encouraging results warrant further evaluation of rIL-2 after ABMT in controlled studies, especially in NHL patients stratified for previous chemosensitivity.

  6. Incidence of interstitial pneumonia after hyperfractionated total body irradiation before autologous bone marrow/stem cell transplantation

    1995-01-01

    Purpose/Objectives Interstitial pneumonia (IP) is a severe complication after allogenic bone marrow transplantation (BMT) with incidence rates between 10 % and 40 % in different series. It is a polyetiologic disease that occurs depending on age, graft vs. host disease (GvHD), CMV-status, total body irradiation (TBI) and immunosuppressive therapy after BMT. The effects of fractionation and dose rate are not entirely clear. This study evaluates the incidence of lethal IP after hyperfractionated TBI for autologous BMT or stem cell transplantation. Materials and Methods Between 1982 and 1992, 182 patients (60 % male, 40 % female) were treated with hyperfractionated total body irradiation (TBI) before autologous bone marrow transplantation. Main indications were leukemias and lymphomas (53 % AML, 21 % ALL, 22 % NHL, 4 % others) Median age was 30 ys (15 - 55 ys). A total dose of 14.4 Gy was applied using lung blocks (12 fractions of 1.2 Gy in 4 days, dose rate 7-18 cGy/min, lung dose 9 - 9.5 Gy). TBI was followed by cyclophosphamide (200 mg/kg). 72 % were treated with bone marrow transplantation, 28 % were treated with stem cell transplantation. Interstitial pneumonia was diagnosed clinically, radiologically and by autopsy. Results 4 patients died most likely of interstitial pneumonia. For another 12 patients interstitial pneumonia was not the most likely cause of death but could not be excluded. Thus, the incidence of lethal IP was at least 2.2 % but certainly below 8.8 %. Conclusion Lethal interstitial pneumonia is a rare complication after total body irradiation before autologous bone marrow transplantation in this large, homogeously treated series. In the autologous setting, total doses of 14.4 Gy can be applied with a low risk for developing interstitial pneumonia if hyperfractionation and lung blocks are used. This falls in line with data from series with identical twins or t-cell depleted marrow and smaller, less homogeneous autologous transplant studies. Thus

    Calcineurin inhibitor-induced pain syndrome is an entity recognized in patients on immunosuppressive therapy after transplantation. Diagnosis is characterized by onset of pain beginning in the setting of an elevated calcineurin-inhibitor trough level. Reducing the medication dose relieves symptoms. Imaging findings can be nonspecific, including bone marrow edema and periosteal reaction. We present the unique case of calcineurin inhibitor-induced pain syndrome in a child and review the imaging findings. (orig.)

    2010-01-01

    Full Text Available Background – There is increasing evidence that the transplanted bone marrow stromal cells (BMSC significantly promote functional recovery after central nervous system (CNS damage in the animal models of various kinds of CNS disorders, including cerebral infarct, brain contusion and spinal cord injury. However, there are several shortages of information when considering clinical application of BMSC transplantation for patients with neurological disorders. In this paper, therefore, we discuss what we should clarify to establish cell transplantation therapy in clinical situation and describe our recent works for this purpose.Methods and Results – The BMSC have the ability to alter their gene expression profile and phenotype in response to the surrounding circumstances and to protect the neurons by producing some neurotrophic factors. They also promote neurite extension and rebuild the neural circuits in the injured CNS. Using optical imaging and MRI techniques, the transplanted BMSC can non-invasively be tracked in the living animals for at least 8 weeks after transplantation. Functional imaging such as PET scan may have the potential to assess the beneficial effects of BMSC transplantation. The BMSC can be expanded using the animal protein-free culture medium, which would maintain their potential of proliferation, migration, and neural differentiation.Conclusion – It is urgent issues to develop clinical imaging technique to track the transplanted cells in the CNS and evaluate the therapeutic significance of BMSC transplantation in order to establish it as a definite therapeutic strategy in clinical situation in the future

    Fanconi anaemia, an autosomal recessive constitutional aplastic anaemia, seems to be related to a DNA repair mechanism defect. Bone marrow transplantation is the only treatment which can cure these patients. Previous attempts at BMT have shown an increased sensitivity to Cyclophosphamide used for the conditioning. Such a sensitivity has also been observed in vitro when Fanconi anaemia cells were incubated with alkylating agents. We have tested the in vivo radiosensitivity and cell repair after skin contact radiotherapy to calculate the irradiation dose which could be tolerated by FA patients. Eight patients have been tested and the results confirmed the suspected increased radiosensitivity in the majority of patients. Following these results, four patients were conditioned with low dose Cyclophosphamide (20 mg/kg) associated with 5 Grays thoraco-abdominal irradiation. all had a take and no major complication of the conditioning regimen. All are alive in good condition from day 51 to day 330 after transplant. Oesophagitis was one major unexpected complication. This study confirms the possibility of curing FA patients with BMT when the conditioning regimen is modified according to the pathophysiology of the disease. (author)

    This paper reports that late renal dysfunction following bone marrow transplantation has been described by a number of centers including the authors own. Total body irradiation seems to play a major causative role. In an effort to decrease the incidence of this renal toxicity, the authors have added customized partial transmission renal blocking to their total body irradiation regimen. The purpose of this study is to evaluate the effect of the renal blocking. The authors total body irradiation dose is 14 Gy. With the shielding used, the kidneys received approximately 12 Gy. Fifty-five adult patients have received total body irradiation with this renal shielding, compared with 73 adult patients who were treated without renal shielding. Eighteen percent (13 of 73) of patients who did not have renal shielding compared with only 7% (4 of 55) of patients with renal shielding have developed late renal dysfunction. Median follow-up in the non-blocked patients is 451 days after transplantation versus 282 days for the blocked patients

  13. Bone Marrow Mononuclear Cell Transplantation Restores Inflammatory Balance of Cytokines after ST Segment Elevation Myocardial Infarction.

    Kirsi Alestalo

    Full Text Available Acute myocardial infarction (AMI launches an inflammatory response and a repair process to compensate cardiac function. During this process, the balance between proinflammatory and anti-inflammatory cytokines is important for optimal cardiac repair. Stem cell transplantation after AMI improves tissue repair and increases the ventricular ejection fraction. Here, we studied in detail the acute effect of bone marrow mononuclear cell (BMMNC transplantation on proinflammatory and anti-inflammatory cytokines in patients with ST segment elevation myocardial infarction (STEMI.Patients with STEMI treated with thrombolysis followed by percutaneous coronary intervention (PCI were randomly assigned to receive either BMMNC or saline as an intracoronary injection. Cardiac function was evaluated by left ventricle angiogram during the PCI and again after 6 months. The concentrations of 27 cytokines were measured from plasma samples up to 4 days after the PCI and the intracoronary injection.Twenty-six patients (control group, n = 12; BMMNC group, n = 14 from the previously reported FINCELL study (n = 80 were included to this study. At day 2, the change in the proinflammatory cytokines correlated with the change in the anti-inflammatory cytokines in both groups (Kendall's tau, control 0.6; BMMNC 0.7. At day 4, the correlation had completely disappeared in the control group but was preserved in the BMMNC group (Kendall's tau, control 0.3; BMMNC 0.7.BMMNC transplantation is associated with preserved balance between pro- and anti-inflammatory cytokines after STEMI in PCI-treated patients. This may partly explain the favorable effect of stem cell transplantation after AMI.

  14. Addition of exogenous cytokines in mixed lymphocyte culture for selecting related donors for bone marrow transplantation

    Jeane Eliete Laguila Visentainer

    Full Text Available CONTEXT: Mixed lymphocyte culturing has led to conflicting opinions regarding the selection of donors for bone marrow transplantation. The association between a positive mixed lymphocyte culture and the development of graft-versus-host disease (GVHD is unclear. The use of exogenous cytokines in mixed lymphocyte cultures could be an alternative for increasing the sensitivity of culture tests. OBJECTIVE: To increase the sensitivity of mixed lymphocyte cultures between donor and recipient human leukocyte antigen (HLA identical siblings, using exogenous cytokines, in order to predict post-transplantation GVHD and/or rejection. TYPE OF STUDY: Prospective study. SETTING: Bone Marrow Transplantation Unit, Universidade Estadual de Campinas. PARTICIPANTS: Seventeen patients with hematological malignancies and their respective donors selected for bone marrow transplantation procedures. PROCEDURES: Standard and modified mixed lymphocyte culturing by cytokine supplementation was carried out using donor and recipient cells typed for HLA. MAIN MEASUREMENTS: Autologous and allogenic responses in mixed lymphocyte cultures after the addition of IL-4 or IL-2. RESULTS: In comparison with the standard method, average responses in the modified mixed lymphocyte cultures increased by a factor of 2.0 using IL-4 (p < 0.001 and 6.4 using IL-2 (p < 0.001, for autologous donor culture responses. For donor-versus-recipient culture responses, the increase was by a factor of 1.9 using IL-4 (p < 0.001 and 4.1 using IL-2 (p < 0.001. For donor-versus-unrelated culture responses, no significant increase was observed using IL-4, and a mean response inhibition of 20% was observed using IL-2 (p < 0.001. Neither of the cytokines produced a significant difference in the unrelated control versus recipient cell responses. CONCLUSION: IL-4 supplementation was the best for increasing the mixed lymphocyte culture sensitivity. However, IL-4 also increased autologous responses, albeit less

    A preparative regimen for allogeneic bone marrow transplantation, consisting of total lymphoid irradiation (TLI) with 750 cGy and cyclophosphamide (CY), was used in five girls with aplastic anemia. All patients received bone marrow from HLA matched/mixed lymphocyte culture negative siblings. In our regimen the 'inverted Y' field to irradiate the pelvic nodes was modified, which did not include the whole pelvic cavity in an attempt to protect the ovaries from irradiation. Although some of the pelvic nodes was supported not to be irradiated in order to protect the ovaries, engraftment occurred in all five patients including four who had been transfused prior to transplantation. All five are alive from 47 days to 1378 days (median 285 days) after transplantation without tranplantation-associated complications. The calculated dose to the ovaries was sixteen percent of the entire dose of the regimen. Both of the two evaluable patients that had received tranplantation just before or during the puberty are developing normal sex maturity including menstruation. This study suggests that our preparative regimen is effective not only for engraftment of the donor marrow but also for protecting the ovaries from irradiation. (author)

    To enhance the grafting efficiency of bone marrow transplantation, lethally Irradiated recipient Kunming mice were transplantation with fetal liver-bone marrow scheduled transplantation. (FL-BMST) The numbers of WBC, nucleated cells were near to normal level 17 d after irradiation in FL-BMST group transplantation with 1 x 10 6 bone marrow cells, the indexes of CFU-E, CFU-GM, CFU-F, CFU-S, were returned to normal; the degree of GVHD in the FL-BMST group was slighter than that in sing bone marrow transplantation group; and the survival rate of mice was 60%, which was significantly higher than that of routine single bone marrow transplantation group. 'Niches' vacated each time could be fully used and be improved, be increased by fetal liver-bone marrow scheduled transplantation, so the homing of stem cells was increased, and the number of transplanted bone marrow cells could be decreased. So this new method was a better method than routine bone singe marrow transplantation

    Bone marrow cells formed similar numbers of 10-days spleen colonies in sublethally (6 Gy) irradiated C57B1/6 mice as in lethally (7.5 Gy) irradiated mice i.e. approximately 20 per 10 5 cells. Numbers of 10 day endogenous spleen colonies in sublethally irradiated mice (0.2 to 0.6 per spleen) did not differ significantly from the numbers in lethally irradiated mice. Yet, transplants of 10 7 coisogenic marrow cells into sublethally irradiated mice resulted in predominantly endogenous recovery of granulocyte system as evidenced by utilization of ''beige'' marker for transplanted cells. Nevertheless, transplanted cells engrafted into sublethally irradiated mice were present in their hemopoietic tissues throughout the observation period of 2 months never exceeding 5 to 10% of cells. Thymus cells stimulated endogenous and exogenous spleen colony formation as well as endogenous granulopoietic recovery. Additionally, they increased both the frequency and absolute numbers of graft-derived granulocytic cells in hemopoietic organs of transplanted mice. They failed, however, to essentially change the quantitative relationships between endogenous and exogenous hemopoietic recovery. These results may suggest that spleen colony studies are not suitable for prediction of events following bone marrow transplant into sublethally irradiated mice. Simultaneously, they have strengthened the necessity for appropriate conditioning of recipients of marrow transplants. (orig.) [de

  18. Sporotrichosis in Renal Transplant Patients

    2013-01-01

    Full Text Available The current report describes two renal transplant recipients who presented with sporotrichosis. In addition, the authors review the general aspects of sporotrichosis in renal transplant recipients reported in the literature. Sporotrichosis is a rare fungal infection in transplant patients and has been reported primarily in renal transplant recipients not treated with antifungal prophylaxis. Extracutaneous forms of sporotrichosis without skin manifestations and no previous history of traumatic injuries have been described in such patients and are difficult to diagnose. Renal transplant recipients with sporotrichosis described in the present report were successfully treated with antifungal therapy including amphotericin B deoxycholate, lipid amphotericin B formulations, fluconazole and itraconazole.

    The best approach for allogeneic haematopoietic stem cell transplantations (alloHCT) in patients with chronic lymphocytic leukaemia (CLL) is unknown. We therefore analysed the impact of procedure- and centre-related factors on 5-year event-free survival (EFS) in a large retrospective study. Data of 684 CLL patients who received a first alloHCT between 2000 and 2011 were analysed by multivariable Cox proportional hazards models with a frailty component to investigate unexplained centre heterogeneity. Five-year EFS of the whole cohort was 37% (95% confidence interval [CI], 34-42%). Larger numbers of CLL alloHCTs (hazard ratio [HR] 0·96, P = 0·002), certification of quality management (HR 0·7, P = 0·045) and a higher gross national income per capita (HR 0·4, P = 0·04) improved EFS. In vivo T-cell depletion (TCD) with alemtuzumab compared to no TCD (HR 1·5, P = 0·03), and a female donor compared to a male donor for a male patient (HR 1·4, P = 0·02) had a negative impact on EFS, but not non-myeloablative versus more intensive conditioning. After correcting for patient-, procedure- and centre-characteristics, significant variation in centre outcomes persisted. In conclusion, further research on the impact of centre and procedural characteristics is warranted. Non-myeloablative conditioning appears to be the preferable approach for patients with CLL. © 2017 John Wiley & Sons Ltd.

  20. Hematopoietic microenvironment. Origin, lineage, and transplantability of the stromal cells in long-term bone marrow cultures from chimeric mice

    Perkins, S.; Fleischman, R.A.

    1988-01-01

    Studies of bone marrow transplant patients have suggested that the stromal cells of the in vitro hematopoietic microenvironment are transplantable into conditioned recipients. Moreover, in patients with myeloproliferative disorders, all of the stromal cells, which include presumptive endothelial cells, appear to be derived from hematopoietic precursors. To confirm these findings, we have constructed two chimeric mouse models: (a) traditional radiation chimeras, and (b) fetal chimeras, produced by placental injection of bone marrow into genetically anemic Wx/Wv fetuses, a technique that essentially precludes engraftment of nonhematopoietic cells. Using two-color indirect immunofluorescence, the stromal cells in long-term bone marrow culture derived from these chimeras were analyzed for donor or host origin by strain-specific H-2 antigens, and for cell lineage by a variety of other specific markers. 75-95% of the stromal cells were shown to be hematopoietic cells of the monocyte-macrophage lineage, based upon donor origin, phagocytosis, and expression of specific hematopoietic surface antigens. The remaining 5-25% of the stromal cells were exclusively host in origin. Apart from occasional fat cells, these cells uniformly expressed collagen type IV, laminin, and a surface antigen associated with endothelial cells. Since these endothelial-like cells are not transplantable into radiation or fetal chimeras, they are not derived from hematopoietic stem cells. The contrast between our findings and human studies suggests either unexpected species differences in the origin of stromal lineages or limitations in the previous methodology used to detect nonhematopoietic stromal cells

    Described are usefulness and future view of regenerative medicine in the treatment of radiation exposure as exemplified by the vascular regeneration by autologous marrow cell transplantation. Vascular endothelial cells (VEC), possessing a high ability to divide, are known sensitive to radiation, which gives damage of blood vessel to alter its permeability leading to apoptosis of VEC, organ/tissue injuries and final damages in the cerebral blood vessels, central nervous system and skin, the acute radiation syndrome (ARS). Authors present successful cases of patients with chronic limb ischemia in the Therapeutic Angiogenesis using Cell Transplantation Trial (TACT), to whom the treatment is conducted with transplantation of autologous marrow monocyte fraction containing endothelial progenitor cells that differentiate to VEC. As well, they touch on a case of the patient encountered in a nuclear accident, mentioning that VEC are found partly derived from the donor after heamatopoietic stem cell transplantation (HSCT). Efficacy of HSCT in a literature is reviewed and commented to be an only limited one in 31 patients of various radiation accidents. However, treatment of ARS where stem cells are target, with regenerative medicine will become more useful in future, as basic and clinical researches will provide requisite findings. (T.I.)

    Recent studies have shown the safety and efficacy of the stem cells derived from bone marrow (BMC) implant with concomitant administration of stimulating factor of granulocyte colonies in patients with acute myocardial infarction with ST segment elevation and in chronic ischemic cardiopathy. An open prospective (before and after) design was made to evaluate the safety and efficacy of cell therapy associated to growth factor administration. The first experience with this kind of therapy is reported. Methodology: this is a 6 months follow-up report of patients with acute and chronic ischemic cardiopathy to who transplant of stem cells derived from bone marrow mobilized with granulocyte colonies growth stimulating factor via coronary arteries or epicardium was realized. Two groups of patients were included: Ten patients with anterior wall infarct and 2. Five patients with chronic ischemic cardiopathy, all with extensive necrosis demonstrated by absence of myocardial viability through nuclear medicine and ejection fraction of less than 40%. Results: significant improvement of ejection fraction from 29.44 ± 3.36 to 37.6 ± 5.3 with p<0.001 and decrease of ventricular systolic and diastolic volume without statistical significance (p =0.31 and 0.4 respectively) were demonstrated. Exercise capacity evidenced by increment in the six minutes test, exercise time and the MET number achieved, increased in a significant way. There were significant changes in the perfusion defect from the second follow-up month and no complications directly related to the stem cells derived from bone marrow transplant or the use of stimulating granulocyte colony factor were presented. Conclusions: this is the first experience of stem cells derived from bone marrow transplant associated to the administration of stimulating granulocyte growth colony factor in which recovery of left ventricular function was demonstrated, as well as improvement in exercise capacity and in the perfusion defect

    The apparition of ciclosporine, immunodepressive drug, has largely improved the organ transplantations. However, the range of blood concentrations must be defined to allow the efficacity of ciclosporine therapy and to avoid toxic reactions, because there are very important variations for a same dosage according to the individuals and the diseases. Relative to the low concentrations to be determined (about one hundred ng/ml), the most useful methods for ciclosporine measurement are based on immunochemical assays. This work compares the two methods: radioimmunoassay (RIA) and fluorescence polarization immunoassay (FPIA) simultaneously performed on several hundred samples. A very significant correlation exists between the two techniques (r = 0.80). The advantages of immunofluorescent assay consists in rapidity, sensibility and facility to realize emergency analysis [fr

    Mechanisms of hematopoietic reconstitution after bone marrow (BM) transplantation remain largely unknown. We applied a computational quantification software application to hybrid 18F-fluorodeoxyglucose positron emission tomography (PET)/computed tomography (CT) images to assess activity and distribution of the hematopoietic system throughout the whole skeleton of recently transplanted patients. Thirty-four patients underwent PET/CT 30 days after either adult stem cell transplantation (allogeneic cell transplantation [ACT]; n = 18) or cord blood transplantation (CBT; n = 16). Our software automatically recognized compact bone volume and trabecular bone volume (IBV) in CT slices. Within IBV, coregistered PET data were extracted to identify the active BM (ABM) from the inactive tissue. Patients were compared with 34 matched controls chosen among a published normalcy database. Whole body ABM increased in ACT and CBT when compared with controls (12.4 ± 3 and 12.8 ± 6.8 vs 8.1 ± 2.6 mL/kg of ideal body weight [IBW], P bones, ABM increased three- and sixfold in CBT and ACT, respectively, compared with controls (0.9 ± 0.9 and 1.7 ± 2.5 vs 0.3 ± 0.3 mL/kg IBW, P transplanted BM into previously abandoned BM sites. © 2015 by The American Society of Hematology.

    The therapeutic effectiveness on murine viral-leukemia of allogeneic or hybrid hematopoietic cells transplanted from leukemia-virus resistant donors was evaluated and compared with that of syngeneic cells. Transplantation of syngeneic cells gave no protection to the viral-leukemic mice. Transplantation of spleen cells from allogeneic donors resulted in early deaths of both leukemic and non-leukemic recipients. Transplantation of hybrid spleen cells resulted in no long-term survival of the leukemic mice. However, there were a number of long-term survivors among the leukemic recipients of allogeneic or hybrid marrow cells. Engraftment of allogeneic marrow resulted in a large number of survivors. Hybrid marrow recipients showed an even better survival, but some leukemia relapses. Tests of the longterm survivors revealed that even though they gave no evidence of leukemia they still harbored the active virus. This suggests that the mechanism of protection may be related to some inherent characteristic of the donor cells rendering them refractory to viral transformation. A difference in graft-versus-host (GvH) response between the leukemic and control mice was also found after transplantation of allogeneic cells. While all of the controls died of GvH reaction, none of the leukemic recipients showed severe GvH response, suggesting a possible effect of the leukemia on histocompatibility. No GvH reaction was found with hybrid marrow engraftment, although some of the leukemic recipients reconstituted with F 1 cells did die of leukemic relapse. (author)

    Twenty patients suffering from malignant hemopathies (mean age 31.7 years) were given hyperfractionated total body irradiation (TBI) as conditioning for T-depleted HLA identical allogeneic bone marrow transplantation. At an average of 12 months (range of 4.5-22 months) follow-up there were two cases of early death and two cases (11%) of rejection. There were no cases of acute or chronic graft versus host disease nor cases of interstitial pneumonitis. The average time for durable engraftment was 22 days. Disease-free survival at 12 months was 65%. To improve the results and further reduce the percent of rejection, the authors propose intensifying the immunosuppressive conditioning by increasing the cyclophosphamide dose and that of TBI so that a total dose of 1560 cGy is reached. 35 refs.; 1 figure

This qualitative approached study was aimed at identifying the attention demands experienced by a patient diagnosed with sharp myeloid leukemia submitted to a bone marrow transplants (BMT following the theoretical reference of attention and attention demands. The data was collected through a semi-structured interview and a-systematic observation, with later content thematic analysis. The results pointed out that the patient in BMT lives multiple attention demands, such as: absence of family, fear of death, uncertainty about the future, restricted physical space, removal from work and too much handling by the Nursing staff, among others.

    In this study, we investigated the factors affecting cell dose harvest and the role of cell dose on outcome. We analysed data from a cohort of 703 patients who underwent unrelated bone marrow transplantation facilitated by IBMDR in GITMO centers between 2002 and 2008. The median-infused cell doses is 3.7 × 10(8)/kg, the correlation between the nucleated cells requested from transplant centers and those harvested by collection centers was adequate. A harvested/requested cells ratio lower than 0.5 was observed only in 3% of harvests. A volume of harvested marrow higher than the median value of 1270 ml was related to a significant lower infused cell dose (χ(2): 44.4; P < 0.001). No patient- or donor-related variables significantly influenced the cell dose except for the recipient younger age (χ(2): 95.7; P < 0.001) and non-malignant diseases (χ(2): 33.8; P < 0.001). The cell dose resulted an independent predictor factor for a better outcome in patients affected by non-malignant disease (P = 0.05) while early disease malignant patients receiving a lower cell dose showed a higher risk of relapse (P = 0.05).

    Bone marrow mesenchymal stem cell transplantation has been shown to be therapeutic in the repair of spinal cord injury. However, the low survival rate of transplanted bone marrow mesenchymal stem cells in vivo remains a problem. Neurotrophin-3 promotes motor neuron survival and it is hypothesized that its transfection can enhance the therapeutic effect. We show that in vitro transfection of neurotrophin-3 gene increases the number of bone marrow mesenchymal stem cells in the region of spinal ...

    Forty patients with plasma cell dyscrasias underwent high-dose chemoradiotherapy and either anti-B-cell monoclonal antibody (MoAb)-treated autologous, anti-T-cell MoAb-treated HLA-matched sibling allogeneic or syngeneic bone marrow transplantation (BMT). The majority of patients had advanced Durie-Salmon stage myeloma at diagnosis, all were pretreated with chemotherapy, and 17 had received prior radiotherapy. At the time of BMT, all patients demonstrated good performance status with Karnofsky score of 80% or greater and had less than 10% marrow tumor cells; 34 patients had residual monoclonal marrow plasma cells and 38 patients had paraprotein. Following high-dose chemoradiotherapy, there were 18 complete responses (CR), 18 partial responses, one non-responder, and three toxic deaths. Granulocytes greater than 500/microL and untransfused platelets greater than 20,000/microL were noted at a median of 23 (range, 12 to 46) and 25 (range, 10 to 175) days posttransplant (PT), respectively, in 24 of the 26 patients who underwent autografting. In the 14 patients who received allogeneic or syngeneic grafts, granulocytes greater than 500/microL and untransfused platelets greater than 20,000/microL were noted at a median of 19 (range, 12 to 24) and 16 (range, 5 to 32) days PT, respectively. With 24 months median follow-up for survival after autologous BMT, 16 of 26 patients are alive free from progression at 2+ to 55+ months PT; of these, 5 patients remain in CR at 6+ to 55+ months PT. With 24 months median follow-up for survival after allogeneic and syngeneic BMT, 8 of 14 patients are alive free from progression at 8+ to 34+ months PT; of these, 5 patients remain in CR at 8+ to 34+ months PT. This therapy has achieved high response rates and prolonged progression-free survival in some patients and proven to have acceptable toxicity. However, relapses post-BMT, coupled with slow engraftment post-BMT in heavily pretreated patients, suggest that such treatment strategies

    Large alternative donor pools provide the potential for selecting a different donor for a second allogeneic (allo) bone or marrow transplant (BMT). As HLA disparity may contribute to the graft-versus-tumor effect, utilizing new mismatched haplotype donors may potentially improve the antitumor activity for relapsed hematologic malignancies despite a previous alloBMT. Data from patients who received a second alloBMT for relapsed hematologic malignancies at Johns Hopkins were analyzed. Outcomes were compared between patients who received a second allograft with the same MHC composition and those who received an allograft with a new mismatched haplotype. Loss of heterozygosity analysis was performed for patients with acute myeloid leukemia (AML) whose first allograft was haploidentical. Between 2005 and 2015, 40 patients received a second BMT for a relapsed hematologic malignancy. The median follow-up is 750 (range, 26 to 2950) days. The median overall survival (OS) in the cohort is 928 days (95% confidence interval [CI], 602 to not reached [NR]); median event-free survival (EFS) for the cohort is 500 days (95% CI, 355 to NR). The 4-year OS is 40% (95% CI, 25% to 64%), and the 4-year EFS is 36% (95% CI, 24% to 55%). The cumulative incidence of nonrelapsed mortality by 2 years was 27% (95% CI, 13% to 42%). The cumulative incidence of grade 3 to 4 acute graft-versus-host disease (GVHD) at 100 days was 15% (95% CI, 4% to 26%); the cumulative incidence of extensive chronic GVHD at 2 years was 22% (95% CI, 9% to 36%). The median survival was 552 days (95% CI, 376 to 2950+) in the group who underwent transplantation with a second allograft that did not harbor a new mismatched haplotype, while it was not reached in the group whose allograft contained a new mismatched haplotype (hazard ratio [HR], .36; 95% CI, .14 to .9; P = .02). EFS was also longer in the group who received an allograft containing a new mismatched haplotype, (NR versus 401 days; HR, .50; 95% CI, .22 to 1

  19. O papel da glutamina na terapia nutricional do transplante de medula óssea The role of glutamine in nutritional support of bone marrow transplantation

    Silvia M. Albertini

    2001-04-01

    Full Text Available A glutamina (L-GLN é um aminoácido que localiza-se preferencialmente no músculo esquelético e é condicionalmente essencial nas situações onde ocorre hipercatabolismo, como no transplante de medula óssea. Nestas situações a suplementação com a L-GLN na terapia nutricional é segura e recomendada. O emprego do aminoácido com objetivo de reduzir os efeitos secundários no TMO como mucosite e manifestações digestivas parece existir. Existem dados que sugerem um efeito profilático da L-GLN em relação à doença veno-oclusiva hepática nos pacientes transplantados. O emprego do aminoácido em combinação com anti-oxidantes, o uso do mesmo via enteral e/ou parenteral, são respostas que devem ser obtidas através de estudos em grupos homogêneos e selecionados de pacientes submetidos ao transplante de medula óssea.Glutamine is an amino acid which is usually found in the skeletal muscles and it is conditionally essential where there is hyper cathabolism as in bone marrow transplantation. In these situations nutritional support therapy using L-GLN supplements is both safe and recommended. There seems to be a use for amino acid with the goal of reducing the secondary effects, such as mucositis and digestive tract manifestations, of these transplants. There are data which suggest a prophylactic effect of the L-GLN in relation to hepatic veno-occlusive disease in transplant patients. The utilisation of amino acid in combination with antioxidants either by enteral or parenteral means, are questions which should be answered through further study of selected and heterogeneous groups of bone marrow transplant patients.

    The current treatment approach for severe aplastic anemia in children is based on studies performed in the 1980s, and updated evidence is required. We retrospectively compared the outcomes of children with acquired severe aplastic anemia who received immunosuppressive therapy within prospective trials conducted by the Japanese Childhood Aplastic Anemia Study Group or who underwent bone marrow transplantation from an HLA-matched family donor registered in the Japanese Society for Hematopoietic Cell Transplantation Registry. Between 1992 and 2009, 599 children (younger than 17 years) with severe aplastic anemia received a bone marrow transplant from an HLA-matched family donor (n=213) or immunosuppressive therapy (n=386) as first-line treatment. While the overall survival did not differ between patients treated with immunosuppressive therapy or bone marrow transplantation [88% (95% confidence interval: 86-90) versus 92% (90-94)], failure-free survival was significantly inferior in patients receiving immunosuppressive therapy than in those undergoing bone marrow transplantation [56% (54-59) versus 87% (85-90); Paplastic anemia.

    1991-01-01

    Following the introduction of bulsulphan and cyclophosphamide (BUCY) conditioning in our unit in 1987, a number of patients noted incomplete scalp hair regrowth following bone marrow transplantation (BMT). Between August 1987 and May 1989, 22 patients had undergone allogeneic or autologous BMT in our unit and we recalled for detailed assessment the 14 who were alive and well at least 6 months post grafting. Six patients had experienced incomplete hair regrowth of varying severity 7-27 months following BMT. All those affected had received BUCY conditioning and the four most severely affected were allogeneic BMT recipients. No patient had received any post-BMT chemotherapy or radiation. None of the patients had evidence of graft-versus-host disease. No laboratory test abnormalities distinguished the affected from the unaffected patients. Despite the relatively small number of patients, our results suggest that BUCY has caused permanent damage to the hair follicles of the affected patients. Prolonged alopecia may markedly impair the quality of life for long-term survivors of BMT and this unexpected complication also has significant medicolegal implications.

    1995-01-01

    From 1986 through 1992, involved-field radiation therapy (IF-RT) was administered to 29 of 86 patients with recurrent Hodgkin's disease (HD) who received a high-dose cyclophosphamide/etoposide regimen with autologous bone marrow transplantation (A-BMT). Patients without a significant history of prior RT received total body irradiation (TBI), initially as a single dose 5-7.5 Gy, and subsequently with fractionated TBI (F-TBI) delivering 12 Gy. Previously irradiated patients received a high-dose BCNU regimen instead of TBI. IF-RT was employed selectively, usually for sites of bulky disease (> 5 cm). IF-RT doses were typically 20 Gy at 2 Gy per fraction for TBI patients and 30-40 Gy at 1.8-2.0 Gy per fraction for non-TBI Patients. Fatal complications developed in four patients while second malignancies have developed in two. The region which received IF-RT was the site of first recurrence in only two cases (7%). With a median follow-up of 28 months, the two-year disease-free survival rate was 44%. For the 22 patients treated by either F-TBI or high-dose BCNU, the 2-year disease-free survival rate was 50% with a median follow up of 29 months. Selective use of IF-RT may increase the chances of complete remission and disease free survival in HD patients with a history of bulky disease

  4. Route of delivery influences biodistribution of human bone marrow-derived mesenchymal stromal cells following experimental bone marrow transplantation

    Wang FJ

    2015-12-01

    Full Text Available Mesenchymal stromal cells (MSCs have shown promise as treatment for graft-versus-host disease (GvHD following allogeneic bone marrow transplantation (alloBMT. Mechanisms mediating in vivo effects of MSCs remain largely unknown, including their biodistribution following infusion. To this end, human bone-marrow derived MSCs (hMSCs were injected via carotid artery (IA or tail vein (TV into allogeneic and syngeneic BMT recipient mice. Following xenogeneic transplantation, MSC biodistribution was measured by bioluminescence imaging (BLI using hMSCs transduced with a reporter gene system containing luciferase and by scintigraphic imaging using hMSCs labeled with [99mTc]-HMPAO. Although hMSCs initially accumulated in the lungs in both transplant groups, more cells migrated to organs in alloBMT recipient as measured by in vivo BLI and scintigraphy and confirmed by ex vivo BLI imaging, immunohistochemistry and quantitative RT-PCR. IA injection resulted in persistent whole–body hMSC distribution in alloBMT recipients, while hMSCs were rapidly cleared in the syngeneic animals within one week. In contrast, TV-injected hMSCs were mainly seen in the lungs with fewer cells traveling to other organs. Summarily, these results demonstrate the potential use of IA injection to alter hMSC biodistribution in order to more effectively deliver hMSCs to targeted tissues and microenvironments.

  5. Booster irradiation to the spleen following total body irradiation. A new immunosuppressive approach for allogeneic bone marrow transplantation

    Lapidot, T.; Singer, T.S.; Salomon, O.; Terenzi, A.; Schwartz, E.; Reisner, Y.

    1988-01-01

    Graft rejection presents a major obstacle for transplantation of T cell-depleted bone marrow in HLA-mismatched patients. In a primate model, after conditioning exactly as for leukemia patients, it was shown that over 99% of the residual host clonable T cells are concentrated in the spleen on day 5 after completion of cytoreduction. We have now corroborated these findings in a mouse model. After 9-Gy total body irradiation (TBI), the total number of Thy-1.2+ cells in the spleen reaches a peak between days 3 and 4 after TBI. The T cell population is composed of both L3T4 (helper) and Lyt-2 (suppressor) T cells, the former being the major subpopulation. Specific booster irradiation to the spleen (5 Gy twice) on days 2 and 4 after TBI greatly enhances production of donor-type chimera after transplantation of T cell-depleted allogeneic bone marrow. Similar enhancement can be achieved by splenectomy on day 3 or 4 after TBI but not if splenectomy is performed 1 day before TBI or 1 day after TBI, strengthening the hypothesis that, after lethal TBI in mice, the remaining host T cells migrate from the periphery to the spleen. These results suggest that a delayed booster irradiation to the spleen may be beneficial as an additional immunosuppressive agent in the conditioning of leukemia patients, in order to reduce the incidence of bone marrow allograft rejection

  6. Mortality of monkeys after exposure to fission neutrons and the effects of autologous bone marrow transplantation

    1978-01-01

    In order to assess the risk of exposure to ionizing radiation in man, and to evaluate the results of therapeutic measures, the mortality of rhesus monkeys irradiated with X-rays and fission neutrons and the effect of autologous bone marrow transplantation have been investigated. The LDsub(50/30d) values for X- and neutron-irradiated monkeys amount to 525 and 260 rad respectively, resulting in an r.b.e. of approximately 2 for the occurrence of the bone marrow syndrome. Protection of the animals by autologous bone marrow transplantation was observed up to doses of 860 rad of X-rays and 440 rad of fission neutrons. After both fission-neutron irradiation and X-irradiation in the lowest range of lethal doses, the bone marrow syndrome was found to occur without the concurrent incidence of the intestinal syndrome. The studies indicate that, for humans accidentally exposed to what would otherwise be lethal doses of fast neutrons, bone marrow transplantation may be beneficial. (author)

    Familial thrombocytopenia is a relatively rare and heterogeneous group of clinical and genetic syndromes of unknown etiology. Recently, mutations in a few hematopoietic transcription factors were implicated in dysmegakaryopoiesis with and without dyserythropoietic anemia. The aim of the present study was to describe the clinical and hematologic picture of members of a Bedouin family with severe congenital thrombocytopenia associated with neutropenia and anemia and to determine the possible involvement of hematopoietic transcription factor genes in their disease. Four members of a Bedouin family presented with severe bleeding tendency, including intracranial hemorrhage in three. Three of the four were successfully treated with allogenic human leukocyte antigen (HLA)-matched bone marrow transplants. Measurements of serum erythropoietin and thrombopoietin levels, bone marrow electron microscopy, and megakaryocytic colony were grown for each patient in addition to DNA amplification and single-strand conformation polymorphism of each exon of the NF-E2, Fli-1, FOG-1, and Gfi-1b in genes. Bone marrow studies revealed dysmegakaryopoiesis and mild dyserythropoiesis. A low number of bone marrow megakaryocyte colony-forming units was found, as well as a slightly elevated serum thrombopoietin level. No mutation was identified in any of the transcription factor genes examined. A unique autosomal recessive bone marrow disorder with prominent involvement of megakaryocytes is described. Defects were not identified in transcription factors affecting the common myeloid progenitor.

    1999-01-01

    The aim of this study was to assess the relationship between radiation therapy (RT) and treatment-related mortality in patients receiving high-dose chemotherapy (HDCT) and autologous bone marrow transplantation (ABMT) for recurrent/refractory Hodgkin's disease (HD). Between December 1986 and December 1992, 59 patients previously treated at the Princess Margaret Hospital underwent HDCT (etoposide 60 mg/kg, melphalan 160 mg/m 2 ) and ABMT, performed for refractory (13 patients) or relapsed (46 patients) HD. RT was incorporated in the salvage treatment with the intent to achieve complete control of disease prior to ABMT. RT was given before ABMT in 33 patients, and after ABMT in 4 patients. Treatment-related (TR) mortality was defined as any death occurring within 100 days of ABMT. Autopsies were performed for all patients with TR deaths. With a median follow-up of 4.6 years (range 1.2-7.4 years), the actuarial overall survival was 41%±14% at 5 years. We observed 37 deaths, and 10 of these were TR deaths. Among the 24 patients who received thoracic RT before ABMT, there were 8 TR deaths, 3 of these solely attributable to radiation pneumonitis. The remaining 5 TR deaths all had respiratory failure with complicating sepsis as a major medical problem. The interval from RT to ABMT was shorter for 8 patients dying of TR death (mean 37 days; range 0-103 days), than for the 16 survivors (mean 105 days; range 0-263 days) (P=0.026). Among 9 patients with ABMT within 50 days of thoracic RT, 6 had TR death. In contrast, among the 35 patients without thoracic RT (26 no RT, 9 non-thoracic RT), there were only 2 TR deaths. The 4 patients treated with mantle RT post-ABMT had no serious pulmonary complications. The use of thoracic RT before HDCT and ABMT was associated with a high post-transplant mortality rate. It was most evident in patients who received thoracic RT within 50 days prior to ABMT, or when the target volume included large volume of lung. We recommend that the use of

    We investigated the effect of Epstein-Barr virus (EBV) serostatus on the overall outcome of allogeneic hematopoietic stem-cell transplantation (allo-HSCT). The study included 11,364 patients who underwent allogeneic peripheral-blood or bone marrow transplantation for acute leukemia between 1997 and 2012. We analyzed the impact of donor and recipient EBV serologic status on overall survival, relapse-free survival, relapse incidence, nonrelapse mortality, and incidence of graft-versus-host disease (GVHD) after allo-HSCT. Patients receiving grafts from EBV-seropositive donors had the same overall survival as patients who received grafts from EBV-seronegative donors (hazard ratio [HR], 1.05; 95% CI, 0.97 to 1.12; P = .23). Seropositive donors also had no influence on relapse-free survival (HR, 1.04; 95% CI, 0.97 to 1.11; P = 0.31), relapse incidence (HR, 1.03; 95% CI, 0.94 to 1.12; P = .58), and nonrelapse mortality (HR, 1.05; 95% CI, 0.94 to 1.17; P = .37). However, in univariate analysis, recipients receiving grafts from seropositive donors had a higher risk of chronic GVHD than those with seronegative donors (40.8% v 31.0%, respectively; P donors, the HR for chronic GVHD was 1.30 (95% CI, 1.06 to 1.59; P = .039). In seropositive patients with seropositive donors, the HR was 1.24 (95% CI, 1.07 to 1.45; P = .016) for acute GVHD and 1.43 (95% CI, 1.23 to 1.67; P donors did not have an increased risk of GVHD. Our data suggest that donor EBV status significantly influences development of acute and chronic GVHD after allo-HSCT. © 2016 by American Society of Clinical Oncology.

    1977-01-01

    Following a single exposure to 1,100 R whole-body irradiation, (C57Bl/6 x A)F 1 hybrid mice were genetically resistant to transplantation of 5 x 10 5 C57 parental bone marrow cells (hybrid resistance). Hybrid resistance was minimally broken by increasing the radiation exposure to 2,200 R, and maximally broken by increasing it to 5,000 R. Following 1,100 R, (C57Bl/6 x A)F 1 hybrid mice were genetically resistant to transplantation of 5 x 10 6 Lewis RBM cells (xenogeneic resistance). This xenogeneic resistance was not even minimally broken following 5,000 R, but was broken following 6,600 R. With different doses of parental or xenogeneic marrow cells, it was found that the amount of irradiation exposure required to break either hybrid resistance or xenogeneic resistance was inversely proportional to the dose of bone marrow cells used

    Neonatal bone marrow transplantation (BMT) could offer a novel therapeutic opportunity for genetic disorders by providing sustainable levels of the missing protein at birth, thus preventing tissue damage. We tested this concept in mucopolysaccharidosis type I (MPS IH; Hurler syndrome), a lysosomal storage disorder caused by deficiency of α-l-iduronidase. MPS IH is characterized by a broad spectrum of clinical manifestations, including severe progressive skeletal abnormalities. Although BMT increases the life span of patients with MPS IH, musculoskeletal manifestations are only minimally responsive if the timing of BMT delays, suggesting already irreversible bone damage. In this study, we tested the hypothesis that transplanting normal BM into newborn MPS I mice soon after birth can prevent skeletal dysplasia. We observed that neonatal BMT was effective at restoring α-l-iduronidase activity and clearing elevated glycosaminoglycans in blood and multiple organs. At 37 weeks of age, we observed an almost complete normalization of all bone tissue parameters, using radiographic, microcomputed tomography, biochemical, and histological analyses. Overall, the magnitude of improvements correlated with the extent of hematopoietic engraftment. We conclude that BMT at a very early stage in life markedly reduces signs and symptoms of MPS I before they appear. © 2015 by The American Society of Hematology.

    Between 1980 and 1993, 326 patients with acute non-lymphoblastic leukemia (ANLL, n=182) and acute lymphoblastic leukemia (ALL, n=144) in complete remission underwent TBI either in single dose (190 patients: 10 Gy administered to the midplane, and 8 Gy to the lungs [STBI]) or in 6 fractions (136 patients: 12 Gy on 3 consecutive days, and 9 Gy to the lungs [FTBI]) before BMT. The patients were analyzed according to 3 instantaneous dose rate groups: 118 patients in the LOW group ({<=}0.048 Gy/min), 188 in the MEDIUM group (>0.048 and {<=}0.09 Gy/min), and 20 in the HIGH group (>0.09 cGy/min). Conditioning chemotherapy consisted of cyclophosphamide (CY) alone in 250 patients, CY and other drugs in 54, and 22 patients were conditioned using combinations without CY. Following TBI, allogeneic and autologous BMT were realized respectively in 118 and 208 patients. Multivariate analyses revealed that the best factors influencing the survival were 1st CR, age {<=}40 years, and BMT after 1985. The RI was influenced independently only by the remission status. On the other hand, the TRM rate was lower in patients who did not experience graft-vs.-host disease (GvHD), and in those treated after 1985 (p=0.0005). GvHD was the only independent factor involved in the development of IP. When considering the cataract incidence, the only independent factor was the instantaneous dose rate. The outcome of BMT patients conditioned with TBI for acute leukemia was not significantly influenced by the TBI technique, and TRM seemed to be lower in patients treated after 1985. On the other hand, cataract incidence was significantly influenced by the instantaneous dose rate.

    Objective: To explore the homing regularity of different doses of bone marrow cell transplantation. Method: An allogeneic mouse model was used. The homing status of different dose groups from the first day to the forth day after transplantation were observed. Results: The rate of positive cells in bone marrow and spleen: differences among four groups was not significant. The rate of positive cells of third day was highest among four days (P<0.01). A phenomenon that homing-mobilization-re-homing could be observed. The homing efficiency: low dose groups were higher than that high dose groups (P<0.01). Conclusion: The homing efficiency of low dose groups is higher than that of the high dose groups in certain range, the routine method of transplanting a large quantities cells by a single injection may be an waste

    Bone healing is a complex and multistep process in which the origin of the cells participating in bone repair is still unknown. The involvement of bone marrow-derived cells in tissue repair has been the subject of recent studies. In the present study, bone marrow-derived cells in bone healing were traced using the GFP bone marrow transplantation model. Bone marrow cells from C57BL/6-Tg (CAG-EGFP) were transplanted into C57BL/6 J wild mice. After transplantation, bone injury was created using a 1.0-mm drill. Bone healing was histologically assessed at 3, 7, 14, and 28 postoperative days. Immunohistochemistry for GFP; double-fluorescent immunohistochemistry for GFP-F4/80, GFP-CD34, and GFP-osteocalcin; and double-staining for GFP and tartrate-resistant acid phosphatase were performed. Bone marrow transplantation successfully replaced the hematopoietic cells into GFP-positive donor cells. Immunohistochemical analyses revealed that osteoblasts or osteocytes in the repair stage were GFP-negative, whereas osteoclasts in the repair and remodeling stages and hematopoietic cells were GFP-positive. The results indicated that bone marrow-derived cells might not differentiate into osteoblasts. The role of bone marrow-derived cells might be limited to adjustment of the microenvironment by differentiating into inflammatory cells, osteoclasts, or endothelial cells in immature blood vessels.

    Full Text Available As complicações pulmonares constituem causa importante de morbidade e mortalidade em doentes submetidos a transplante de medula óssea. Os testes de função pulmonar são utilizados rotineiramente na avaliação antes e no acompanhamento após o transplante. A revisão sistemática da literatura mostrou que a presença de alterações nos testes de função pulmonar antes do transplante de medula não esteve relacionada com maior incidência de complicações pulmonares pós-transplante. Entretanto, alterações destes testes após o transplante estiveram relacionadas com maior incidência de complicações respiratórias. Desta forma, embora as alterações dos testes de função pulmonar pré-transplante não tenham sido de valor preditivo positivo na detecção precoce de complicações respiratórias pós-transplante, os mesmos podem ser úteis na comparação com os testes realizados após o transplante e devem fazer parte da avaliação de doentes candidatos ao transplante de medula óssea.The pulmonary function test plays an important role in the management of pulmonary complications after bone marrow transplantation. Although its utility in helping to predict the likelihood of developing post transplant pulmonary complications and mortality is not well established, current data indicate that pre-transplant pulmonary function tests are important as a reference for the interpretation of post transplant pulmonary function tests and for identifying patients at high risk of developing pulmonary complications and/or mortality after bone marrow transplantation.

  20. Use of G-CSF-stimulated marrow in allogeneic hematopoietic stem cell transplantation settings: a comprehensive review.

    Chang, Ying-Jun; Huang, Xiao-Jun

    2011-01-01

    In recent years, several researchers have unraveled the previously unrecognized effects of granulocyte colony-stimulating factor (G-CSF) on hematopoiesis and the immune cell functions of bone marrow in healthy donors. In human leukocyte antigen-matched or haploidentical transplant settings, available data have established the safety of using G-CSF-stimulated bone marrow grafts, as well as the ability of this source to produce rapid and sustained engraftment. Interestingly, G-CSF-primed bone marrow transplants could capture the advantages of blood stem cell transplants, without the increased risk of chronic graft-versus-host disease that is associated with blood stem cell transplants. This review summarizes the growing body of evidence that supports the use of G-CSF-stimulated bone marrow grafts as an alternative stem cell source in allogeneic hematopoietic stem cell transplantation. © 2010 John Wiley & Sons A/S.

    Intensive high-dose chemotherapy with autologous stem-cell support has become a common treatment strategy for non-Hodgkin's lymphomas. A cost-identification analysis was conducted comparing 10 patients autografted with PBSC to 10 others autografted with BM. The analysis included harvest and graft until graft day +100 and was carried out from the point of view of the hospital setting. Resources used, logistic and direct medical costs per patient were identified, and sensitivity analyses performed. The cost distribution was different. Stem cell harvest was more expensive for PBPC ($9030) and BM ($4745); on the other hand, hospitalization from graft to discharge from hospital cost savings with PBSC were about $10666. After discharge from hospital, costs were similar and cheaper in both groups. For the overall study the PBPC procedure was less expensive than ABMT, $35381 and $41759 respectively, with cost savings of $6378. The number of days spent in hospital and blood bank costs were the major cost factors. This study was based on a single pathology, non-Hodgkin's lymphoma, and the actual hospital records for each patient situation as opposed to a clinical trial, and our results were consistent with different previous studies carried out in different health care systems.

    1987-01-01

    The optimal dose rate and fractionation schedules for total body irradiation (TBI) in bone marrow transplantation (BMT) are presently unknown. This study compares several fractionation and dose rate schedules that are currently in clinical use. C/sub 3/H/HeJ were given TBI and the bone marrow survival fraction was calculated using the CFU's assay. Irradiation was given as low dose rate (LDR) at 5 cGy/min or high dose rate (HDR) at 80 cGy/min, in single fraction (SF) and fractionated (FX) regimens. These results indicate no increase in survival for the normal bone marrow stem cells with fractionation either at high or low dose-rates. In fact, fractionation seemed to decrease the bone marrow survival over single fraction radiation

    To enrich our national database with data of rare diseases by analyzing molecular diagnosis and hematopoietic stem cell transplantation (HSCT) in children with inherited bone marrow failure syndromes (IBMFS). Next-generation sequencing (NGS)-based genetic diagnosis panel was applied for the clinical diagnosis and management of IBMFS. Retrospective analysis was performed on clinical and genetic data of 17 consecutive children who received HSCT over a long time interval (November. 2005-June 2015). Three patients were diagnosed only by clinical manifestation before 2012. After that NGS-based genetic diagnosis panel was used to identify IBMFS-related genes in 12/14.IBMFS patients (except two Diamond-Blackfan anemia (DBA) patients). Two Fanconi anemia (FA) patients were confirmed to be new variations through family-genotype-analysis and 3 families accepted prenatal diagnosis to avoid birth of affected fetuses. Seventeen IBMFS patients (10 FA,5 DBA and 2 dyskeratosis congenital (DKC)) were treated with HSCT from matched sibling donors (n=2), matched unrelated donors (n=8) or mismatched unrelated donors (n=7). The source of stem cells for transplantation included peripheral blood (n=12) and cord blood (n=5). With regard to the conditioning regimens, FA and DKC patients received fludarabine-based reduced intensity conditioning, while DBA patients received classical busulfan-based myeloablative conditioning. Median age at the time of HSCT was 36 months (7-156 months). The number of infused mononuclear cells and CD34⁺ cells was (10.6 ± 6.7) × 10⁸ and (5.9 ± 7.0) × 10⁶ per kilogram of recipient body weight, respectively. The median number of days to neutrophil recovery was 13 days after HSCT (range: 10-19 days). Platelet recovery was faster in the PBSCT group than in the CBT group ((16.3 ± 6.0) days vs. (30.0 ± 17.1) days,t=-2.487,P=0.026). During a median follow-up of 17 months (range: 2-114 months), except one FA patient who was transplanted with HLA

    2009-12-01

    Bone marrow transplantation (BMT) is used to treat various conditions, ranging from immune disorders to many types of cancer. The critical complexity of patients and the environment in which BMT nurses work can lead to stress, burnout, and, ultimately, poor retention. This study aimed to investigate nurses' perceptions of work-related stress and burnout as well as current support systems for nurses. The study included 30 BMT staff nurses from a large pediatric medical center in the midwestern United States. Critical illness or acuity of patients was reported as the most stressful factor; long work hours was the least stressful factor. Most nurses perceived moderate to high levels of emotional exhaustion, and 33% reported moderate levels of depersonalization. Fifty percent perceived high levels of personal accomplishment, despite the critical illness or acuity of their patients, demanding patient families, rotating shifts, short staffing, and caring for dying patients. Most nurses felt that support systems were in place and that staff was accessible, but most respondents were undecided about the helpfulness of the support systems. Results suggest that support systems may significantly affect work satisfaction and feelings of accomplishment for BMT nurses.

    From July 1985 to December 1989, 72 evaluable patients aged 6-51 (median age 27) suffering from hematological malignancies received allo-geneic bone marrow transplant (BMT) depleted of T-lymphocytes to reduce risks of graft-versus-host-disease (GvHD); 57 were matched and 15 mis-matched. Three different conditioning regiments were used in an effort to enhance cytoreduction without increase extramedullary toxicity. Mis-matched patients were treated with more immunosuppressive regimens. Total body irradiation (TBI) was given in 3 doses/day, 5 h apart over 4 days for a total of 12 fractions. The dose to the lungs was 14.4, 15.6 and 9 Gy according to the conditioning regimen. The incidence of inter-stitial pneumonia (IP) was 12.3 percent in matched and 46.7 in mis-matched patients. The results seem to indicate that lung toxicity is correlated with the intensity of the conditioning regimen, the stage of disease and, in mismatched patients, with the degree of human leucocyte antigen (HLA) disparity and the poor post-BMT reconstitution, rather than the radiotherapy dose delivered to the lungs. On the contrary, the hyperfractionated scheme adopted, the absence of GvHD and, perhaps, the post-TBI administration of cyclophosphamide all seem to have contributed to the low incidence of IP in the matched patients.

    In most cases, bone marrow transplantation is preceded by a conditioning regimen employing irradiation and/or cytotoxic drugs. The authors are searching for better fractionation schedules in order to optimize the conditioning regimen prior to transplantation of stem-cell-enriched bone marrow. They have determined damage to the gastrointestinal tract in dogs and mice after total body irradiation in mice and dogs following a number of fractionation schedules, and these results are presented. The schedules were chosen such as to minimize the interval between irradiation and the bone marrow transplantation and to maximize clinical feasibility. (Auth./C.F.)

    Patients with follicular lymphoma (FL) experiencing early therapy failure (ETF) within 2 years of frontline chemoimmunotherapy have poor overall survival (OS). We analyzed data from the Center for International Blood and Marrow Transplant Research (CIBMTR) and the National LymphoCare Study (NLCS) to determine whether autologous hematopoietic cell transplant (autoHCT) can improve outcomes in this high-risk FL subgroup. ETF was defined as failure to achieve at least partial response after frontline chemoimmunotherapy or lymphoma progression within 2 years of frontline chemoimmunotherapy. We identified 2 groups: the non-autoHCT cohort (patients from the NLCS with ETF not undergoing autoHCT) and the autoHCT cohort (CIBMTR patients with ETF undergoing autoHCT). All patients received rituximab-based chemotherapy as frontline treatment; 174 non-autoHCT patients and 175 autoHCT patients were identified and analyzed. There was no difference in 5-year OS between the 2 groups (60% versus 67%, respectively; P = .16). A planned subgroup analysis showed that patients with ETF receiving autoHCT soon after treatment failure (≤1 year of ETF; n = 123) had higher 5-year OS than those without autoHCT (73% versus 60%, P = .05). On multivariate analysis, early use of autoHCT was associated with significantly reduced mortality (hazard ratio, .63; 95% confidence interval, .42 to .94; P = .02). Patients with FL experiencing ETF after frontline chemoimmunotherapy lack optimal therapy. We demonstrate improved OS when receiving autoHCT within 1 year of treatment failure. Results from this unique collaboration between the NLCS and CIBMTR support consideration of early consolidation with autoHCT in select FL patients experiencing ETF.

    Within the context of the SFGM-TC's 6th workshop series on the harmonization of clinical practices, our workshop proposes a standardization of the informed consent process for hematopoietic stem cell donors and recipients leading up to an autologous or allogenic transplantation. All informed consent was for bone marrow or peripheral stem cell donors, and mononuclear/lymphocyte donors according to usual procedures. The informed consent for autologous and allogenic related or unrelated adults and pediatric transplantation patients have been included. A first step has been conducted for collecting in advance the informed consent forms used routinely in all francophone transplantation centers. In a second step, a comprehensive version has been re-written by a multidisciplinary team. For the purposes of understanding the risks and advantages, language has been carefully considered and streamlined. In the third step, texts were sent to stem cell transplantation experts, experts at the French biomedical agency (agence de la biomédecine [ABM]), law specialists, members of the ethical committee of the French society of hematology and several transplant recipients to be edited and proofread.

    Data on 68 146 hematopoietic stem cell transplants (HSCTs) (53% autologous and 47% allogeneic) gathered by 1566 teams from 77 countries and reported through their regional transplant organizations were analyzed by main indication, donor type and stem cell source for the year 2012. With transplant rates ranging from 0.1 to 1001 per 10 million inhabitants, more HSCTs were registered from unrelated 16 433 donors than related 15 493 donors. Grafts were collected from peripheral blood (66%), bone marrow (24%; mainly non-malignant disorders) and cord blood (10%). Compared with 2006, an increase of 46% total (57% allogeneic and 38% autologous) was observed. Growth was due to an increase in reporting teams (18%) and median transplant activity/team (from 38 to 48 HSCTs/team). An increase of 167% was noted in mismatched/haploidentical family HSCT. A Strengths, Weaknesses, Opportunities, Threats (SWOT) analysis revealed the global perspective of WBMT to be its major strength and identified potential to be the key professional body for patients and authorities. The limited data collection remains its major weakness and threat. In conclusion, global HSCT grows over the years without plateauing (allogeneic>autologous) and at different rates in the four World Health Organization regions. Major increases were observed in allogeneic, haploidentical HSCT and, to a lesser extent, in cord blood transplantation.

    Aplastic anemia is usually treated with immunosuppression or allogeneic transplant, depending on patient and disease characteristics. Syngeneic transplant offers a rare treatment opportunity with minimal transplant-related mortality, and offers an insight into disease mechanisms. We present here a retrospective analysis of all syngeneic transplants for aplastic anemia reported to the European Group for Blood and Marrow Transplantation. Between 1976 and 2009, 88 patients received 113 transplants. Most transplants (n=85) were preceded by a conditioning regimen, 22 of these including anti-thymocyte globulin. About half of transplants with data available (39 of 86) were followed by posttransplant immunosuppression. Graft source was bone marrow in the majority of cases (n=77). Transplant practice changed over time with more transplants with conditioning and anti-thymocyte globulin as well as peripheral blood stem cells performed in later years. Ten year overall survival was 93% with 5 transplant-related deaths. Graft failure occurred in 32% of transplants. Risk of graft failure was significantly increased in transplants without conditioning, and with bone marrow as graft source. Lack of posttransplant immunosuppression also showed a trend towards increased risk of graft failure, while anti-thymocyte globulin did not have an influence. In summary, syngeneic transplant is associated with a significant risk of graft failure when no conditioning is given, but has an excellent long-term outcome. Furthermore, our comparatively large series enables us to recommend the use of pre-transplant conditioning rather than not and possibly to prefer peripheral blood as a stem cell source.

    Full Text Available Background: Gonadal dysfunction is one of the short and long-term side effects following bone marrow transplantation (BMT. We assessed hypophyseal-gonadal axis after BMT by low dose busulfan-cyclophosphamide conditioning regimen (120 mg/kg. Methods: In this cohort study, we evaluated gonadal function in 48 patients (25 pubert males and 23 pubert females. Data were obtained by history, physical examination, LH, FSH, prolactin, estradiol (E2, progesterone, testosterone and semen analysis before BMT and in 6 and 12 months of post-BMT. Results: Gonadal axis in 16 male subjects (64% was normal before BMT and remained normal in 6 subjects (37% 12 months post BMT. In another 10 patients (63%, hypogonadism was started in 6 months post BMT. Spermatogenesis failure (31%, low level of testosterone (25% and spermatogenesis failure plus low level of testosterone in 12.5% were found. Gonadal axis in 20 female subjects (87% was normal before BMT, but remained normal only in 10% of subject until the end of the study. Other patients (90% had primary hypogonadism in 6 months of post BMT. Conclusion: There is a high prevalence of gonadal dysfunction following BMT in both adult sexes (especially in female patients. Therefore, regular gonadal assessment is recommended following BMT.

    Objective: To investigate if low dose radiation can stimulate the haematogenesis reconstitution of the recipient after bone marrow transplantation in mice. Methods: Bone marrow cells were irradiated in vitro by different low dose radiation and then cultured in vitro. 3 H-TdR incorporation was used to measure the reproductive activity of cells, and then the radiation dose with the best stimulating effect was determined. The donator myeloid cells were exposed to low dose radiation before the recipient mice received bone marrow transplantation; then the irradiated myeloid cells were infused to the recipient; and lastly, the counts of peripheral blood cells (PBC) and bone marrow mononuclear cells (BMMNC) were monitored in order to observe the effect of low dose radiation on haematogenesis reconstitution of the recipient animal after bone marrow transplantation. Results: The reproductive activity of the bone marrow cells irradiated by 6 and 8 cGy could be improved significantly in vitro. When the recipient mice received bone marrow transplantation of the myeloid cells after low dose radiation, the counts of BMMNC and PBC were higher than those in the control group (P<0.05). Conclusions: Low dose radiation can stimulate the haematogenesis reconstitution of the recipient after bone marrow transplantation. (authors)

    Severe myelosuppression is a common side effect of radiotherapy or chemotherapy. As a mean to stimulate the full-lineage blood cell recovery from severe myelosuppression, sublethally irradiated animals were used to evaluate immunological effect of interleukin IL-12 in bone marrow transplanted animals. Isologous bone marrow (BM), from the same inbred strain, were given to male rats, 1 hour post whole body gamma irradiation at a single dose level of 5 Gy and subcutaneous injection of 100 ng/ml IL-12. Irradiation induced a significant drop in haematological values, blood glutathione(GSH) as well as bone marrow viability associated with a significant elevation of serum malondialdehyde (MDA). Related to immunological data, tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6) also recorded a significant depression. Irradiated animals receiving BM and IL-12 showed significantly elevated body and spleen weights, erythrocytes count (RBCs), hemoglobin content (Hb) and hemotocrit value (Hct %) besides, white blood cells (WBCs)and its differential count, as well as GSH, while MDA was significantly depressed as compared to the irradiated group. Bone marrow viability was significantly increased while IL-6 and TNF-α were normalized. The curative action of IL-12 enforcing significant innate response could trigger and augment adaptive immune response by bone marrow transplantation, hence improving oxidative stress. IL-12 administration is proposed as a complementary strategy to treat radiation-induced path-physiology and trapping free radicals accumulations after irradiation.

    Full Text Available An important factor in improving functional recovery from spinal cord injury using stem cells is maximizing the number of transplanted cells at the lesion site. Here, we established a contusion model of spinal cord injury by dropping a weight onto the spinal cord at T 7-8 . Superparamagnetic iron oxide-labeled bone marrow mesenchymal stem cells were transplanted into the injured spinal cord via the subarachnoid space. An outer magnetic field was used to successfully guide the labeled cells to the lesion site. Prussian blue staining showed that more bone marrow mesenchymal stem cells reached the lesion site in these rats than in those without magnetic guidance or superparamagnetic iron oxide labeling, and immunofluorescence revealed a greater number of complete axons at the lesion site. Moreover, the Basso, Beattie and Bresnahan (BBB locomotor rating scale scores were the highest in rats with superparamagnetic labeling and magnetic guidance. Our data confirm that superparamagnetic iron oxide nanoparticles effectively label bone marrow mesenchymal stem cells and impart sufficient magnetism to respond to the external magnetic field guides. More importantly, superparamagnetic iron oxide-labeled bone marrow mesenchymal stem cells can be dynamically and non-invasively tracked in vivo using magnetic resonance imaging. Superparamagnetic iron oxide labeling of bone marrow mesenchymal stem cells coupled with magnetic guidance offers a promising avenue for the clinical treatment of spinal cord injury.

    2018-01-01

    60 samples of G-CSF-primed bone marrow (39 cancer patients and 21 healthy donors) to be used for transplantation to cancer patients were analyzed and compared by main characteristics with historical control and 13 bone marrow samples from control patient with mastopathy. Basing on morphological and multicolor flow cytometry findings certain characteristics of G-CSF-primed bone marrow were discovered, such as a significant increase in blast count in cancer patients as compared to donors and control patients (p<0.037), a higher neutrophil maturation index (p<0.001) and a lower percentage of mature lymphocytes (p<0.008) as compared to the control group. Among lymphocyte populations G-CSF-priming was associated with a significant increase in the total of mature CD3+ T-cells and CD8+ T-killers (p<0.0001) and a decrease in CD56+CD3- and/or CD16+CD3- NK-cells (p<0.006) both in cancer patients and healthy donors in comparison with the controls.

    There are few specific data available concerning quality of life (QOL) of survivors of unrelated donor bone marrow transplantation (UD-BMT). The procedure is expensive, difficult and is being employed increasingly yet we have little information concerning the QOL of survivors to justify this intervention. In this study, 20 long-term (>1 year post-BMT) survivors were studied with four self report questionnaires designed to assess quality of life, satisfaction with life, social support and employment status. Overall, satisfaction with life measures was above average but there was dissatisfaction with physical strength and appearance. The post-transplant employment data indicates that 60% of long-term survivors returned to full-time work and 15% to part-time work. Failure to return to work was not correlated with graft-versus-host disease (GVHD), relapse, age at or time since transplant. In general, there was a good correlation between the clinician's and patient's view of their health but the clinician's assessment of the patients mental health and energy was higher than the patients reported. Further research is required in the area of QOL post-UD-BMT. This will enable transplant physicians to counsel patients better pre-BMT and to evaluate fully the results achieved by different centres performing the procedure.

  20. Engraftment Efficiency after Intra-Bone Marrow versus Intravenous Transplantation of Bone Marrow Cells in a Canine Nonmyeloablative Dog Leukocyte Antigen-Identical Transplantation Model.

    An intra-bone marrow (IBM) hematopoietic stem cell transplantation (HSCT) is assumed to optimize the homing process and therefore to improve engraftment as well as hematopoietic recovery compared with conventional i.v. HSCT. This study investigated the feasibility and efficacy of IBM HSCT after nonmyeloablative conditioning in an allogeneic canine HSCT model. Two study cohorts received IBM HSCT of either density gradient (IBM-I, n = 7) or buffy coat (IBM-II, n = 6) enriched bone marrow cells. An historical i.v. HSCT cohort served as control. Before allogeneic HSCT experiments were performed, we investigated the feasibility of IBM HSCT by using technetium-99m marked autologous grafts. Scintigraphic analyses confirmed that most IBM-injected autologous cells remained at the injection sites, independent of the applied volume. In addition, cell migration to other bones occurred. The enrichment process led to different allogeneic graft volumes (IBM-I, 2 × 5 mL; IBM-II, 2 × 25 mL) and significantly lower counts of total nucleated cells in IBM-I grafts compared with IBM-II grafts (1.6 × 10 8 /kg versus 3.8 × 10 8 /kg). After allogeneic HSCT, dogs of the IBM-I group showed a delayed engraftment with lower levels of donor chimerism when compared with IBM-II or to i.v. HSCT. Dogs of the IBM-II group tended to reveal slightly faster early leukocyte engraftment kinetics than intravenously transplanted animals. However, thrombocytopenia was significantly prolonged in both IBM groups when compared with i.v. HSCT. In conclusion, IBM HSCT is feasible in a nonmyeloablative HSCT setting but failed to significantly improve engraftment kinetics and hematopoietic recovery in comparison with conventional i.v. HSCT.

  1. Invasive Pulmonary Aspergillosis in a Sickle Cell Patient Transplant Recipient: A Successful Treatment

    Katia Paciaroni

    2015-08-01

    Full Text Available Sickle Cell Anaemia (SCA is the most common inherited blood disorder and is associated with severe morbidity and decreased survival. Allogeneic Haematopoietic Stem Cell Transplantation (HSCT is the only curative approach. Nevertheless the decision to perform a marrow transplant includes the risk of major complications  and mortality transplant related. The infections represent the main cause of mortality for SCA patients undergoing transplant. Invasive Pulmonary Aspergillosis (IPA is a devastating opportunistic infection and remains a significant cause of morbidity and mortality in HSCT recipients. Data regarding IPA in the setting of SCA are lacking. In the present report,  we describe a patient with SCA who developed IPA after allogeneic bone marrow transplant. The fungal infection was treated by systemic antifungal therapy in addition to the surgery, despite  mild chronic GVHD and with continuing immunosuppression therapy. This case shows that IPA occurring in bone marrow recipient with SCA can be successful treated

  2. Bone marrow stromal cell transplantation mitigates radiation-induced gastrointestinal syndrome in mice.

    Subhrajit Saha

    Full Text Available Nuclear accidents and terrorism presents a serious threat for mass casualty. While bone-marrow transplantation might mitigate hematopoietic syndrome, currently there are no approved medical countermeasures to alleviate radiation-induced gastrointestinal syndrome (RIGS, resulting from direct cytocidal effects on intestinal stem cells (ISC and crypt stromal cells. We examined whether bone marrow-derived adherent stromal cell transplantation (BMSCT could restitute irradiated intestinal stem cells niche and mitigate radiation-induced gastrointestinal syndrome.Autologous bone marrow was cultured in mesenchymal basal medium and adherent cells were harvested for transplantation to C57Bl6 mice, 24 and 72 hours after lethal whole body irradiation (10.4 Gy or abdominal irradiation (16-20 Gy in a single fraction. Mesenchymal, endothelial and myeloid population were characterized by flow cytometry. Intestinal crypt regeneration and absorptive function was assessed by histopathology and xylose absorption assay, respectively. In contrast to 100% mortality in irradiated controls, BMSCT mitigated RIGS and rescued mice from radiation lethality after 18 Gy of abdominal irradiation or 10.4 Gy whole body irradiation with 100% survival (p<0.0007 and p<0.0009 respectively beyond 25 days. Transplantation of enriched myeloid and non-myeloid fractions failed to improve survival. BMASCT induced ISC regeneration, restitution of the ISC niche and xylose absorption. Serum levels of intestinal radioprotective factors, such as, R-Spondin1, KGF, PDGF and FGF2, and anti-inflammatory cytokines were elevated, while inflammatory cytokines were down regulated.Mitigation of lethal intestinal injury, following high doses of irradiation, can be achieved by intravenous transplantation of marrow-derived stromal cells, including mesenchymal, endothelial and macrophage cell population. BMASCT increases blood levels of intestinal growth factors and induces regeneration of the irradiated

    1996-01-01

    The purpose of this report was to evaluate long-term survival and morbidity of fractioned total body irradiation (TBI) prior to allogeneicbone marrow transplantation (BMT) for leukemia. From June 1985 to May 1992, 94 patients with acute leukemia and chronic myelogenous leukemia (CML), were treated with high dose cyclophosphamide(CY) and fractionated TBI to a total dose of 12 Gy in six fractions prior to allogeneic BMT. The Kaplan-Meier 5-year overall survival and disease-free survival were 53% +-6 and 48%+- respectively for patients with standard risk disease (first remission of acute leukemia and first chronic phase of CML), and 24%+-7 and 21%+-6 for patients with more advanced disease (p=3D0.01). The incidence of interstitial pneumonitis (IP), venoocclusive disease of the liver (VOD) and grade=3D>II acute graft-versus-host disease (GVHD) were respectively 15%, 29% and 51%. Fractionated TBI combined with high dose CY before allogeneic BMT for leukemia is an effective treatment in prolonging relapse-free survival witha low incidence of lung toxicity. (Author) 13 refs

  4. Cryotherapy effect on oral mucositis severity among recipients of bone marrow transplantation: a literature review.

    Tayyem, Abdel-Qader Mahmoud

    2014-08-01

    Oral mucositis is a distressing toxic effect of cancer therapy and one of the major side effects of the myeloablative conditioning used to prepare patients for bone marrow transplantation (BMT). Oral cryotherapy is one of the recent modalities used to prevent and manage oral mucositis. The purpose of this review is to clarify the cryotherapy effect on oral mucositis severity among patients receiving myeloablative conditioning followed by BMT. A literature search was performed using six different electronic databases: CINAHL®, MEDLINE®, Nursing Ovid, PubMed, Springer, and Science Direct. Six articles were deemed relevant and included in this review. Oral mucositis increases mortality rate, length of hospital stay, opioid use, and the need for parenteral nutrition usage. It also decreases patient's quality of life and his or her desire to complete treatment. However, oral cryotherapy significantly minimizes the incidence and severity of oral mucositis and decreases secondary oral mucositis complications. Using oral cryotherapy concurrently with a regular oral care protocol can improve its efficacy for preventing and managing oral mucositis. Additional studies should be conducted to create standard oral cryotherapy protocols.

  5. Reconstitution of the myeloid and lymphoid compartments after the transplantation of autologous and genetically modified CD34+ bone marrow cells, following gamma irradiation in cynomolgus macaques

    Full Text Available Abstract Background Prolonged, altered hematopoietic reconstitution is commonly observed in patients undergoing myeloablative conditioning and bone marrow and/or mobilized peripheral blood-derived stem cell transplantation. We studied the reconstitution of myeloid and lymphoid compartments after the transplantation of autologous CD34+ bone marrow cells following gamma irradiation in cynomolgus macaques. Results The bone marrow cells were first transduced ex vivo with a lentiviral vector encoding eGFP, with a mean efficiency of 72% ± 4%. The vector used was derived from the simian immunodeficiency lentivirus SIVmac251, VSV-g pseudotyped and encoded eGFP under the control of the phosphoglycerate kinase promoter. After myeloid differentiation, GFP was detected in colony-forming cells (37% ± 10%. A previous study showed that transduction rates did not differ significantly between colony-forming cells and immature cells capable of initiating long-term cultures, indicating that progenitor cells and highly immature hematopoietic cells were transduced with similar efficiency. Blood cells producingeGFP were detected as early as three days after transplantation, and eGFP-producing granulocyte and mononuclear cells persisted for more than one year in the periphery. Conclusion The transplantation of CD34+ bone marrow cells had beneficial effects for the ex vivo proliferation and differentiation of hematopoietic progenitors, favoring reconstitution of the T- and B-lymphocyte, thrombocyte and red blood cell compartments.

    Bowles, C.A.; Bull, M.; McCormick, K.; Kadin, M.; Lucas, D.

    1980-01-01

    Thirty dogs with spontaneous lymphomas were administered two to six cycles of chemotherapy and were randomized into 3 groups to receive 800 rads of total body irradiation and autologous bone marrow transplantation. Of 10 dogs irradiated after chemotherapy-induced remission and infused with remission marrow (group 1), 8 (80%) had successful grafts and experienced remissions lasting 62 to 1024 days. Of 9 dogs irradiated during remission and infused with remission marrow mixed with autologous tumor cells (group 2), 6 (66%) had remission lasting 15 to 45 days. Eleven dogs with progressive tumor growth (relapse) following chemotherapy were irradiated and infused with remission marrow (group 3). Tumor remission lasting 39 to 350 days was observed in 5 dogs (45%) in this group, and 6 dogs died in less than 30 days. Dogs in groups 1 to 3 had median survival times of 216, 60, and 45 days, respectively. The prolonged survival times for dogs in group 1 compared to dogs in groups 2 and 3 suggest that protocols involving irradiation and autologous marrow grafting in this model would be most effective when these protocols are applied to animals having a minimum tumor burden at the time of irradiation and when the grafting is done with tumor-free autologous marrow

  7. EFFECT ON LIFESPAN OF HIGH YIELD NONMYELOABLATING TRANSPLANTATION OF BONE MARROW FROM YOUNG TO OLD MICE

    2013-08-01

    Full Text Available Tissue renewal is a well-known phenomenon by which old and dying-off cells of various tissues of the body are replaced by progeny of local or circulating stem cells (SC. An interesting question is whether donor stem cells are capable to prolong the lifespan of an ageing organism by tissue renewal.. In this work we investigated the possible use of bone marrow SC for lifespan extension. To this purpose, chimeric C57BL/6 mice were created by transplanting bone marrow from young 1.5-month donors to 21.5-month-old recipients. Transplantation was carried out by means of a recently developed method which allowed to transplant without myeloablation up to 1.5×108 cells, that is, about 25 % of the total BM cells of the mouse. As a result, the mean survival time, counting from the age of 21.5 months, the start of the experiment, was +3.6 and +5.0 (± 0.1 months for the control and experimental groups, respectively, corresponding to a 39% ± 4% increase in the experimental group over the control. In earlier studies on BM transplantation a considerably smaller quantity of donor cells (5×106 was used, about 1 % of the total own BM cells. The recipients before transplantation were exposed to a lethal (for control animals X-ray dose which eliminated the possibility of studying the lifespan extension by this method.

  8. Dose response and factors related to interstitial pneumonitis after bone marrow transplant

    Sampath, Sagus; Schultheiss, Timothy E.; Wong, Jeffrey

    2005-01-01

    Purpose: Total body irradiation (TBI) and chemotherapy are common components of conditioning regimens for bone marrow transplantation. Interstitial pneumonitis (IP) is a known regimen-related complication. Using published data of IP in a multivariate logistic regression, this study sought to identify the parameters in the bone marrow transplantation conditioning regimen that were significantly associated with IP and to establish a radiation dose-response function. Methods and Materials: A retrospective review was conducted of articles that reported IP incidence along with lung dose, fractionation, dose rate, and chemotherapy regimen. In the final analysis, 20 articles (n = 1090 patients), consisting of 26 distinct TBI/chemotherapy regimens, were included in the analysis. Multivariate logistic regression was performed to determine dosimetric and chemotherapeutic factors that influenced the incidence of IP. Results: A logistic model was generated from patients receiving daily fractions of radiation. In this model, lung dose, cyclophosphamide dose, and the addition of busulfan were significantly associated with IP. An incidence of 3%-4% with chemotherapy-only conditioning regimens is estimated from the models. The α/β value of the linear-quadratic model was estimated to be 2.8 Gy. The dose eliciting a 50% incidence, D 50 , for IP after 120 mg/kg of cyclophosphamide was 8.8 Gy; in the absence of chemotherapy, the estimated D 50 is 10.6 Gy. No dose rate effect was observed. The use of busulfan as a substitute for radiation is equivalent to treating with 14.8 Gy in 4 fractions with 50% transmission blocks shielding the lung. The logistic regression failed to find a model that adequately fit the multiple-fraction-per-day data. Conclusions: Dose responses for both lung radiation dose and cyclophosphamide dose were identified. A conditioning regimen of 12 Gy TBI in 6 daily fractions induces an IP incidence of about 11% in the absence of lung shielding. Shielding the lung

  9. Transplantation of homologous bone marrow cells to lethally irradiated mice: changes in the spleen

    Viktora, L; Hach, P; Zoubkova, M

    1975-01-01

    Bone marrow cell suspensions were administered intravenously to lethally irradiated mice. The number of colonies in the spleen and the regeneration of hematopoietic tissue in the spleen were studied on the 9th day after irradiation and transplantation. From a comparison of the histological picture and weight of the spleens, the authors conclude that the degree of regeneration of hematopoiesis in the spleen after irradiation and transplantation is reflected in the weight of the spleen as well as in the number of hematopoietic colonies.

  10. Bone marrow transplantation in aplastic anaemia using cyclophosphamide and total lymphoid irradiation

    Jansen, J.; Zwaan, F.E.; Noordijk, E.M.

    1980-01-01

    Six patients with severe aplastic anaemia received a bone-marrow graft after conditioning with cyclophosphamide and total lymphoid irradiation (TLI). No rejections occurred. Acute graft-versus-host disease developed in 3 patients and was fatal in one. Another patient died from systemic aspergillus infection. Chronic GVHD of the skin developed in a patient who was grafted with bone marrow from her HLA-phenotypically identical father. These data suggest that conditioning with cyclophosphamide and TLI is a promising regimen. (orig.) [de

  11. Pulmonary infections in the late period after allogeneic bone marrow transplantation: chest radiography versus computed tomography

    Schueller, Gerd; Matzek, Wolfgang; Kalhs, Peter; Schaefer-Prokop, Cornelia

    2005-01-01

    Purpose: To analyze the capabilities of chest roentgenogram (CXR) and computed tomography (CT) in the evaluation of pulmonary infectious disease in the late period (>100 days) after allogeneic bone marrow transplantation (BMT). Methods: Ninety-four matched CXR and CT examinations were performed for clinical suspicion of infectious lung disease. The time gap between CXR and CT was 48 h at maximum. The image pairs were correlated with the patients' clinical course and with the results of diagnostic bronchoalveolar lavage (BAL). An unremarkable clinical course over the subsequent seven days after imaging and/or negative microbiological culture served as the basis for excluding infectious lung disease. Positive microbiological culture and/or improvement of symptoms after antibiotic therapy were considered as evidence of infectious disease. Results: The correlation with the clinical course and/or BAL revealed a significantly higher sensitivity, negative predictive value, and accuracy for CT than for CXR (89% versus 58%, P < 0.0001; 78% versus 47%, P < 0.0001; 90% versus 68%, P < 0.0001, respectively). CT was significantly more diagnostic in BAL verified fungal and bacterial infections (P < 0.05). Conclusion: CT is significantly superior to CXR in the evaluation of infectious pulmonary disease in the late phase after BMT. Therefore, an unremarkable CXR should be followed by a CT scan to reliably detect or to accurately exclude early pulmonary infection in these patients

  12. Impact of Drug Therapy, Radiation Dose, and Dose Rate on Renal Toxicity Following Bone Marrow Transplantation

    Cheng, Jonathan C.; Schultheiss, Timothy E.; Wong, Jeffrey Y.C.

    2008-01-01

    Purpose: To demonstrate a radiation dose response and to determine the dosimetric and chemotherapeutic factors that influence the incidence of late renal toxicity following total body irradiation (TBI). Methods and Materials: A comprehensive retrospective review was performed of articles reporting late renal toxicity, along with renal dose, fractionation, dose rate, chemotherapy regimens, and potential nephrotoxic agents. In the final analysis, 12 articles (n = 1,108 patients), consisting of 24 distinct TBI/chemotherapy conditioning regimens were included. Regimens were divided into three subgroups: adults (age ≥18 years), children (age <18 years), and mixed population (both adults and children). Multivariate logistic regression was performed to identify dosimetric and chemotherapeutic factors significantly associated with late renal complications. Results: Individual analysis was performed on each population subgroup. For the purely adult population, the only significant variable was total dose. For the mixed population, the significant variables included total dose, dose rate, and the use of fludarabine. For the pediatric population, only the use of cyclosporin or teniposide was significant; no dose response was noted. A logistic model was generated with the exclusion of the pediatric population because of its lack of dose response. This model yielded the following significant variables: total dose, dose rate, and number of fractions. Conclusion: A dose response for renal damage after TBI was identified. Fractionation and low dose rates are factors to consider when delivering TBI to patients undergoing bone marrow transplantation. Drug therapy also has a major impact on kidney function and can modify the dose-response function

  13. Late effects on gonadal function of cyclophosphamide, total-body irradiation, and marrow transplantation

    Sanders, J.E.; Buckner, C.D.; Leonard, J.M.; Sullivan, K.M.; Witherspoon, R.P.; Deeg, H.J.; Storb, R.; Thomas, E.D.

    1983-01-01

    One hundred thirty-seven patients had gonadal function evaluated 1-11 years after marrow transplantation. All 15 women less than age 26 and three of nine older than age 26 who were treated with 200 mg/kg cyclophosphamide recovered normal gonadotropin levels and menstruation. Five have had five pregnancies resulting in three live births, one spontaneous abortion, and one elective abortion. Three of 38 women who were prepared with 120 mg/kg cyclophosphamide and 920-1200 rad total-body irradiation had normal gonadotropin levels and menstruation. Two had pregnancies resulting in one spontaneous and one elective abortion. Of 31 men prepared with 200 mg/kg cyclophosphamide, 30 had normal luteinizing hormone levels, 20 had normal follicle-stimulating hormone levels, and 10 of 15 had spermatogenesis. Four have fathered five normal children. Thirty-six of 41 men prepared with 120 mg/kg cyclophosphamide and 920-1750 rad total-body irradiation had normal luteinizing hormone levels, ten had normal follicle-stimulating hormone levels, and 2 of 32 studied had spermatogenesis. One has fathered two normal children. It was concluded that cyclophosphamide does not prevent return of normal gonadal function in younger women and in most men. Total-body irradiation prevents return of normal gonadal function in the majority of patients

  14. Cataract-free interval and severity of cataract after total body irradiation and bone marrow transplantation: influence of treatment parameters

    Kempen-Harteveld, M. Loes van; Struikmans, Henk; Kal, Henk B.; Tweel, Ingeborg van der; Mourits, Maarten; Verdonck, Leo F.; Schipper, Jan; Battermann, Jan J.

    Purpose: To determine prospectively the cataract-free interval (latency time) after total body irradiation (TBI) and bone marrow transplantation (BMT) and to assess accurately the final severity of the cataract. Methods and Materials: Ninety-three of the patients who received TBI as a part of their conditioning regimen for BMT between 1982 and 1995 were followed with respect to cataract formation. Included were only patients who had a follow-up period of at least 23 months. TBI was applied in one fraction of 8 Gy or two fractions of 5 or 6 Gy. Cataract-free period was assessed and in 56 patients, who could be followed until stabilization of the cataract had occurred, final severity of the cataract was determined using a classification system. With respect to final severity, two groups were analyzed: subclinical low-grade cataract and high-grade cataract. Cataract-free period and final severity were determined with respect to type of transplantation, TBI dose, and posttransplant variables such as graft versus host disease (GVHD) and steroid treatment. Results: Cataract incidence of the analyzed patients was 89%. Median time to develop a cataract was 58 months for autologous transplanted patients. For allogeneic transplanted patients treated or not treated with steroids, median times were 33 and 46 months, respectively. Final severity was not significantly different for autologous or allogeneic patients. In allogeneic patients, however, final severity was significantly different for patients who had or had not been treated with steroids for GVHD: 93% versus 35% high-grade cataract, respectively. Final severity was also different for patients receiving 1 x 8 or 2 x 5 Gy TBI, from patients receiving 2 x 6 Gy as conditioning therapy: 33% versus 79% high-grade cataract, respectively. The group of patients receiving 2 x 6 Gy comprised, however, more patients with steroid treatment for GVHD. So the high percentage of high-grade cataract in the 2 x 6 Gy group might also

    Full Text Available Bone marrow mesenchymal stem cells (BMMSCs have shown immunosuppressive activity in transplantation. This study was designed to determine whether BMMSCs could improve outcomes of small bowel transplantation in rats.Heterotopic small bowel transplantation was performed from Brown Norway to Lewis rats, followed by infusion of BMMSCs through the superficial dorsal veins of the penis. Controls included rats infused with normal saline (allogeneic control, isogeneically transplanted rats (BN-BN and nontransplanted animals. The animals were sacrificed after 1, 5, 7 or 10 days. Small bowel histology and apoptosis, cytokine concentrations in serum and intestinal grafts, and numbers of T regulatory (Treg cells were assessed at each time point.Acute cellular rejection occurred soon after transplantation and became aggravated over time in the allogeneic control rats, with increase in apoptosis, inflammatory response, and T helper (Th1/Th2 and Th17/Treg-related cytokines. BMMSCs significantly attenuated acute cellular rejection, reduced apoptosis and suppressed the concentrations of interleukin (IL-2, IL-6, IL-17, IL-23, tumor necrosis factor (TNF-α, and interferon (IFN-γ while upregulating IL-10 and transforming growth factor (TGF-β expression and increasing Treg levels.BMMSCs improve the outcomes of allogeneic small bowel transplantation by attenuating the inflammatory response and acute cellular rejection. Treatment with BMMSCs may overcome acute cellular rejection in small bowel transplantation.

    ABO-incompatible (ABOi) hematopoietic stem cell transplants (HSCTs) can present challenges in the blood bank. During transplantation, patients receive components that are ABO-compatible with both the donor graft and recipient; this practice can strain group O red blood cell (RBC) inventories.1 In addition, there are risks for acute hemolysis at the time of infusion and in the early post-transplant period.1,2 In ABO major-incompatible bone marrow HSCTs, which contain significant quantities of donor RBCs that are ABOi with recipient plasma, it is common to perform a RBC depletion of the bone marrow in an effort to minimize hemolysis at the time of infusion.2 Furthermore, patients with high-titer ABO antibodies may undergo a prophylactic, pre-transplant plasma exchange to further reduce the risk of acute hemolysis, delayed RBC engraftment, and pure RBC aplasia.2-4 ABO minor-incompatible HSCTs, in which donor plasma is ABOi with the recipient, have less risk for hemolysis at the time of infusion but can result in transient hemolysis approximately 10-21 days post-transplant, especially in patients undergoing nonmyeloablative HSCT and/or patients who have not received methotrexate for graft-versus-host-disease (GVHD) prophylaxis.1-4 In these patients, viable donor B-lymphocytes in the graft may expand and produce ABO antibodies capable of hemolyzing patient RBCs.

  18. Immunological Enhancement of Interferon Alpha Treatment to Allogeneic Bone Marrow Transplantation in Irradiated Rats

    2011-01-01

    The Influence of the biological response modifiers: interferon alpha (IFN-α) and bone marrow transplantation (BMT) on stimulation of blood cell recovery and boosting the immunological response were investigated in this work. Male rats received BMT 3 h post total body ?-irradiation of 5 Gy and were injected with 10 units of IFN-α weekly for 5 weeks. Irradiation induced a significant decrease in blood parameters, reduced glutathione (GSH) as well as bone marrow lymphocyte count and viability. Immunological data revealed that tumour necrosis factor alpha (TNF-α) and interleukin-2 (IL-2) recorded a significant depression while lipid peroxidation (MDA) was conversely elevated. White blood cells (WBC), erythrocytes (RBC), haemoglobin (Hb), haematocrit (Hct), lymphocytes and GSH in irradiated animals receiving BMT and IFN-α, were significantly elevated, while MDA was significantly depressed as compared to the irradiated group. Bone marrow lymphocytic count and viability percentage were significantly increased while IL-2 and TNF-α were normalized. The curative action of IFN-α enforcing significant innate response could trigger and augment adaptive immune response by bone marrow transplantation. Such therapies boosting both components of immunity would be considered a potential strategy for irradiation treatment

    1983-01-01

    The transplantation of hemopoietic cells into adequately pretreated recipients represents one of the most promising approaches in the treatment of immunohematological disorders such as aplastic anemia, immunodeficiency diseases, leukemias and malignant lymphomas. The basic property of the hemopoietic cells permitting such therapeutic procedure, namely, the capacity of hemopoietic precursors to actively proliferate and differentiate in recipients suffering the consequences of various kinds of hemopoietic failure, represents the subject of the present review. The main cell populations addressed in the subsequent sections are the hemopoietic precursor cells. Mature end cells and in particular lymphocytes did not receive as much attention.

    2016-01-01

    Data on 68,146 hematopoietic stem cell transplants (HSCT) (53% autologous and 47% allogeneic) gathered by 1566 teams from 77 countries and reported through their regional transplant organizations were analyzed by main indication, donor type and stem cell source for the year 2012. With transplant rates ranging from 0.1 to 1001 per 10 million inhabitants, more HSCT were registered from unrelated 16,433 than related 15,493 donors. Grafts were collected from peripheral blood (66%), bone marrow (24%; mainly non-malignant disorders) and cord blood (10%). Compared to 2006, an increase of 46% total (57% allogeneic and 38% autologous) was observed. Growth was due to an increase in reporting teams (18%) and median transplant activity/team (from 38 to 48 HSCT/team). An increase of 67% was noted in mismatched/haploidentical family HSCT. A SWOT analysis revealed the global perspective of WBMT to be its major strength and identified potential to be the key professional body for patients and authorities. The limited data collection remains its major weakness and threat. In conclusion, global HSCT grows over the years without plateauing (allogeneic>autologous) and at different rates in the four WHO regions. Major increases were observed in allogeneic, haploidentical HSCT and, to a lesser extent, in cord blood. PMID:26901703

    Nemec, Stefan Franz; Marlovits, Stefan; Trattnig, Siegfried

    2009-01-01

    Background and objective: The assessment of bone marrow edema-like signal intensity in magnetic resonance imaging (MRI) in patients after osteochondral autograft transplantation (OCT) in the knee joint is a parameter of yet indefinite value. This study determines the prevalence of persistent edema-like signal intensity in OCT patients and evaluates the correlation between edema and morphological imaging findings of the graft and clinical pain symptoms. Materials and methods: In this longitudinal observational study, 10 patients after OCT were followed by MRI prospectively 1 month, 3 months, 6 months, 12 months, and 24 months post-operatively. All MR examinations were performed on a 1.0 T MR unit with the same protocol using a modified scoring system (magnetic resonance observation of cartilage repair tissue-MOCART) for evaluation. Edema-like signal intensity in and beneath the osteochondral graft was assessed in its prevalence and graded using a coronal short tau inversion recovery fast spin echo (STIR-FSE) sequence: grade 1, normal; grade 2, moderate (diameter 2 cm). The finding of edema-like signal intensity was correlated with graded parameters describing the morphology of the repair tissue assessed in a sagittal dual FSE sequence including: (a) surface of repair tissue: grade 1, intact; grade 2, damaged. (b) Cartilage interface: grade 1, complete; grade 2, incomplete. (c) Bone interface: grade 1, complete; grade 2, delamination. The finding of edema-like signal intensity was also correlated with the KOOS pain score assessing knee pain after 12 months. Results: Initially, after 1 month the prevalence of edema-like signal intensity was 70% (7/10 patients) and finally after 24 months 60% (6/10 patients). We found no significant relationship between the prevalence and degree of edema-like signal intensity and parameters describing the morphology of the repair tissue. Also the clinical pain score did not show significant correlation with edema. Conclusion

    Disease recurrence following stem cell transplantation (SCT) remains a major problem. Despite the sensitivity of leukaemias to chemotherapy and irradiation, conventional conditioning before SCT is limited by significant organ toxicity. Targeted irradiation of bone marrow and spleen by radioimmunotherapy may provide considerable dose escalation, with limited toxicity to non-target organs. In this study, 27 patients with high-risk or relapsing leukaemia were treated with rhenium-188-labelled CD66a,b,c,e radioimmunoconjugates ( 188 Re-mAb) specific for normal bone marrow in addition to conventional conditioning with high-dose chemotherapy and 12 Gy total body irradiation prior to SCT. A mean activity of 10.2±2.1 (range 6.9-15.8) GBq 188 Re-mAb was administered intravenously. Acute side-effects were assessed according to the CTC classification and patient outcome was determined. Mean radiation doses (Gy; range in parentheses) to relevant organs and whole body were as follows: 13.1 (6.5-22) to bone marrow, 11.6 (1.7-31.1) to spleen, 5.0 (2.0-11.7) to liver, 7.0 (2.3-11.6) to kidneys, 0.7 (0.3-1.3) to lungs and 1.4 (0.8-2.1) to the whole body. Stem cells engrafted in all patients within 9-18 days post SCT. Acute organ toxicity of grade II or less was observed. During follow-up for 25.4±5.3 (range 18-34) months, 4/27 (15%) patients died from relapse, and 9/27 (33%) from transplantation-related complications. Fourteen patients (52%) are still alive and in ongoing complete clinical remission. Radioimmunotherapy with the bone marrow-seeking 188 Re-labelled CD66 mAb can double the dose to bone marrow and spleen without undue extramedullary acute organ toxicity, when given in addition to high-dose chemotherapy and 12 Gy TBI before allogeneic SCT. This intensified conditioning regimen may reduce the relapse rate of high-risk leukaemia. (orig.)

    Hematopoietic stem cell transplantation (HSCT) using an optimized conditioning regimen is essential for the long-term survival of patients with inherited bone marrow failure syndromes (IBMFS). We report HSCT in 24 children with Fanconi anemia (FA, n = 12), Diamond-Blackfan anemia (DBA, n = 7), and dyskeratosis congenita (DC, n = 5) from a single HSCT center. The graft source was peripheral blood stem cells (n = 19) or cord blood stem cells (n = 5). FA and DC patients received reduced-intensity conditioning, while DBA patients had myeloablative conditioning. The median numbers of infused mononuclear cells and CD34+ cells were 14.20 × 10 8 /kg and 4.3 × 10 6 /kg, respectively. The median time for neutrophil and platelet recovery was 12 and 18 days, respectively. Complete donor engraftment was achieved in 23 of 24 patients. There was one primary graft failure. During a median follow-up of 27.5 months (range, 2-130 months), the overall survival in all patients was 95.8%. The incidence of grade II-III acute graft versus host disease (GvHD) and chronic GvHD was 29.2% and 16.7%, respectively. We conclude that HSCT can be a curative option for patients with IBMFS. Modification of the conditioning regimen based on the type of disease may lead to encouraging long-term outcomes.

  4. Evaluation of stem cell reserve using serial bone marrow transplantation and competitive repopulation in a murine model of chronic hemolytic anemia

    Maggio-Price, L.; Wolf, N.S.; Priestley, G.V.; Pietrzyk, M.E.; Bernstein, S.E.

    1988-01-01

    Serial transplantation and competitive repopulation were used to evaluate any loss of self-replicative capacity of bone marrow stem cells in a mouse model with increased and persistent hemopoietic demands. Congenic marrows from old control and from young and old mice with hereditary spherocytic anemia (sphha/sphha) were serially transplanted at 35-day intervals into normal irradiated recipients. Old anemic marrow failed or reverted to recipient karyotype at a mean of 3.5 transplants, and young anemic marrow reverted at a mean of 4.0 transplants, whereas controls did so at a mean of 5.0 transplants. In a competitive assay in which a mixture of anemic and control marrow was transplanted, the anemic marrow persisted to 10 months following transplantation; anemic marrow repopulation was greater if anemic marrow sex matched with the host. It is possible that lifelong stress of severe anemia decreases stem cell reserve in the anemic sphha/sphha mouse marrow. However, marginal differences in serial transplantation number and the maintenance of anemic marrow in a competition assay would suggest that marrow stem cells, under prolonged stress, are capable of exhibiting good repopulating and self-replicating abilities

    The objective was to evaluate the precision of the absorbed radiation doses in bone marrow transplant therapy during whole body irradiation. Two-hundred CaSO 4 :Dy + teflon tablets were calibrated in air and in 'phantom'. These tablets were randomly selected and divided in groups of five in the patients' body. The dosimetric readings were obtained using a Harshaw 4000A reader. Nine patients had their entire bodies irradiated in parallel and opposite laterals in a cobalt-60 Alcion II model, with a dose rate of 0.80 Gy/min at 80.5 cm, {(10 ? 10) cm 2 field. The dosimetry of this unit was performed using a Victoreen 500 dosimeter. For the determination of the mean dose at each point evaluated, the individual values of the tablets calibrated in air or 'phantom' were used, resulting in a build up of 2 mm to superficialize the dose at a distance of 300 cm. In 70% of the patients a variation of less than 5% in the dose was obtained. In 30% of the patients this variation was less than 10%, when values obtained were compared to the values calculated at each point. A mean absorption of 14% was seen in the head, and an increase of 2% of the administered dose was seen in the lungs. In patients with latero-lateral distance greater than 35 cm the variation between the calculated doses and the measured doses reached 30% of the desired dose, without the use of compensation filters. The measured values of the absorbed doses at the various anatomic points compared to the desired doses (theoretic) presented a tolerance of ± 10%, considering the existent anatomical differences and when using the individual calibration factors of the tablets.

    Purpose: Contribution of total body irradiation (TBI) to renal toxicity in children undergoing the bone marrow transplant (BMT) remains controversial. We report our institutional retrospective study that evaluates the frequency of acute and chronic renal dysfunction in children after using total body irradiation (TBI) conditioning regimens. Materials and methods: Between 1995 and 2003, 60 children with hematological malignancies underwent TBI as part of a conditioning regimen before allogeneic BMT. Patients received 4-14 Gy at 1.75-2 Gy/fraction in six-eight fractions. Lung shielding was used in all patients to limit lung dose to less than 10 Gy; renal shielding was not utilized. All patients had baseline renal function assessment and renal dysfunction post-BM was mainly evaluated on the basis of persistent serum creatinine elevation at acute (0-90 days) and chronic (>90 days) intervals after completion of BMT. Results: Acute renal dysfunction (ARD) was documented in 27 patients (45%); the majority had concurrent diagnosis of veno-occlusive disease (VOD) or graft-versus-host disease (GVHD) and other potential causes (sepsis, antibiotic). The risk for delayed renal dysfunction (DRD) at 1 year approached 25% for surviving patients. The ARD was strongly linked with the risk of the DRD. There was no statistically significant relationship between ARD, DRD and underlying diagnosis, GVHD, VOD or TBI doses with both univariate and multivariate analyses. The younger age (<5 years) had significantly increased risk for the development of ARD (p = 0.011). Conclusion: Our analysis validates high incidence of renal dysfunction in the pediatric BMT population. In contrast to other reports we did not find total body irradiation dose to be a risk factor for renal dysfunction. Future prospective studies are needed to assess risk factors and interventions for this serious toxicity in children following allogeneic BM

    For treatment of severe aplastic anemia, immunosuppressive therapy with horse antithymocyte globulin results in superior response and survival compared with rabbit antithymocyte globulin. This relative benefit may be different in the setting of transplantation as rabbit antithymocyte globulin results in more profound immunosuppression. We analyzed 833 severe aplastic anemia transplants between 2008 and 2013 using human leukocyte antigen (HLA)-matched siblings (n=546) or unrelated donors (n=287) who received antithymocyte globulin as part of their conditioning regimen and bone marrow graft. There were no differences in hematopoietic recovery by type of antithymocyte globulin. Among recipients of HLA-matched sibling transplants, day 100 incidence of acute (17% versus 6%, P aplastic anemia. Copyright© 2017 Ferrata Storti Foundation.

  9. Detection of bone marrow involvement in patients with cancer

    Federico, M.; Silingardi, V.; Wright, R.M.

    1989-01-01

    Current methods for the study of bone marrow to evaluate possible primary or metastatic cancers are reviewed. Bone marrow biopsy, radionuclide scan, computed tomography and magnetic resonance imaging (MRI) are analyzed with regard to their clinical usefulness at the time of diagnosis and during the course of the disease. Bone marrow biopsy is still the examination of choice not only in hematologic malignancies but also for tumors that metastasize into the marrow. Radionuclide scans are indicated for screening for skeletal metastases, except for those from thyroid carcinoma and multiple myeloma. Computed tomography is useful for cortical bone evaluation. MRI shows a high sensitivity in finding occult sites of disease in the marrow but its use has been restricted by high cost and limited availability. However, the future of MRI in bone marrow evaluation seems assured. MRI is alredy the method of choice for diagnosis of multiple myeloma, when radiography is negative, and for quantitative evaluation of lymphoma when a crucial therapeutic decision (i.e. bone marrow transplantation) must be made. Finally, methods are being developed that will enhance the sensitivity and specificity of MRI studies of bone marrow

    2011-01-01

    Mesenchymal stem cells (MSCs) have been studied widely for their potential to differentiate into various lineage cells including neural cells in vitro and in vivo. To investigate the influence of the developing host environment on the integration and morphological and molecular differentiation of MSCs, human bone marrow-derived mesenchymal stem cells (BM-MSCs) were transplanted into the developing mouse retina. Enhanced green fluorescent protein (GFP)-expressing BM-MSCs were transplanted by intraocular injections into mice, ranging in ages from 1 day postnatal (PN) to 10 days PN. The survival dates ranged from 7 days post-transplantation (DPT) to 28DPT, at which time an immunohistochemical analysis was performed on the eyes. The transplanted BM-MSCs survived and showed morphological differentiation into neural cells and some processes within the host retina. Some transplanted cells expressed microtubule associated protein 2 (MAP2ab, marker for mature neural cells) or glial fibrillary acid protein (GFAP, marker for glial cells) at 5PN 7DPT. In addition, some transplanted cells integrated into the developing retina. The morphological and molecular differentiation and integration within the 5PN 7DPT eye was greater than those of other-aged host eye. The present findings suggest that the age of the host environment can strongly influence the differentiation and integration of BM-MSCs

  11. Transplantation of neurotrophin-3-transfected bone marrow mesenchymal stem cells for the repair of spinal cord injury.

    2014-08-15

    Bone marrow mesenchymal stem cell transplantation has been shown to be therapeutic in the repair of spinal cord injury. However, the low survival rate of transplanted bone marrow mesenchymal stem cells in vivo remains a problem. Neurotrophin-3 promotes motor neuron survival and it is hypothesized that its transfection can enhance the therapeutic effect. We show that in vitro transfection of neurotrophin-3 gene increases the number of bone marrow mesenchymal stem cells in the region of spinal cord injury. These results indicate that neurotrophin-3 can promote the survival of bone marrow mesenchymal stem cells transplanted into the region of spinal cord injury and potentially enhance the therapeutic effect in the repair of spinal cord injury.

    The incidence of cutaneous melanoma has rapidly increased in the white population over the last decades. It has been estimated that the incidence doubles world-wide every 10 years. Different risk factors have been identified, including immunosuppression. The aim of our study-was to determine the relative risk of developing melanoma in the organ transplant population and the clinical and histological features of their melanomas. This retrospective study was conducted with the collaboration of 9 University Hospital Centers: Besançon, Brest, Caen, Dijon, Lille, Lyon, Nantes, Paris (Pitié-Salpétrière) and Rennes. A questionnaire was sent to the different departments of dermatology of these hospitals to obtain information on patients who had presented a melanoma after a transplantation between 1971 and 1997. During this period, there were 12,477 organ transplant recipients in the transplantation units of these 9 hospitals. Average follow-up for these patients was about 5 years and the average duration of immunosuppressive therapy was about 4.5 years. Among 12,477 organ transplant recipients, we found 17 cases of melanoma but no data could be obtain on one case: 14 occurred in renal transplant recipients and 3 in cardiac transplant recipients. Clinical and histological data were only available in 16 patients. The average time between transplantation and diagnosis of melanoma was 63 months, but it was 5 times shorter for 2 patients who had a past history of melanoma before transplantation. Two patients had a mucosal melanoma; for the cutaneous melanomas, 2 appeared on Dubreuilh melanosis, 2 were in situ melanomas, 7 were superficial spreading melanomas and 3 were nodular melanomas. The histological review of 11 cutaneous melanomas revealed a precursor nevus in 6 cases and a weak or no stroma reaction in 7/7 cases. Complete excision of the melanoma was performed in all patients except one with anorectal melanoma. Four patients died of visceral metastasis within a mean

    Full Text Available Rationale: Intravenous administration of Glutamine dipeptides (Gln has been proposed as treatment of oral mucositis following a bone marrow transplant (BMT. Objective: To establish the effects of intravenous Gln supplementation upon the severity of oral mucositis after BMT. Study design: Retrospective, analytical. Study serie: Records from 25 patients (Males: 56.0%; BMT cause: Leukemia: 64.0% who developed oral mucositis (Grades III – IV: 48.0% after BMT (Autologous: 44.0% at the "Juan Tanca Marengo" Hospital (Guayaquil, Ecuador between 2009 – 2017. Glutamine source: Dipeptiven©®: 13 grams of Gln suspended in 100 milliliters of a 20% solution of the alanine-glutamine dipeptide (Fresenius-Kabi©®, Germany. Materials and Methods: Gln-treated patients received 3(4.0% of the treatment leg, 5 (20.0%; 6 (12.0%; 7 (48.0%; or 10 (16.0% doses of the dipeptide until resolution of the symptoms. Impact of Gln was estimated from changes observed in the severity and duration of mucositis, white blood cell counts, and body weight regarding 25 non-Gln treated patients (Males: 68.0%; Leukemias: 32.0%; Autologous graft: 68.0%; Grade III – IV mucositis: 48.0%. Results: Intravenously-administered Gln shortened duration of oral mucositis: Gln-Treated: 12.5 ± 5.1 days vs. Non-Gln Treated: 21.3 ± 17.8 days (p < 0.05. Also, intravenous Gln marginally ameliorated loss of body weight: Gln-Treated -4.5 ± 5.5% vs. Non-Gln Treated: -7.5 ± 5.7% (p = 0.07. Conclusions: Intravenous Gln administration shortens duration of oral mucositis following BMT. Gln effect might be translated to a lesser weight loss in patients with oral mucositis.

    The use of a cytomegalovirus (CMV)-seronegative donor for a CMV-seronegative allogeneic hematopoietic stem cell transplant (HSCT) recipient is generally accepted. However, the importance of donor serostatus in CMV-seropositive patients is controversial. A total of 49 542 HSCT patients, 29 349 seropositive and 20 193 seronegative, were identified from the European Group for Blood and Marrow Transplantation database. Cox multivariate models were fitted to estimate the effect of donor CMV serological status on outcome. Seronegative patients receiving seropositive unrelated-donor grafts had decreased overall survival (hazard ratio [HR], 1.13; 95% confidence interval [CI], 1.06-1.21; P donors, whereas no difference was seen in patients receiving HLA-matched sibling grafts. Seropositive patients receiving grafts from seropositive unrelated donors had improved overall survival (HR, 0.92; 95% CI, .86-.98; P donors, if they had received myeloablative conditioning. This effect was absent when they received reduced-intensity conditioning. No effect was seen in patients grafted from HLA-identical sibling donors. The same association was found if the study was limited to patients receiving transplants from the year 2000 onward. We confirm the negative impact on overall survival if a CMV-seropositive unrelated donor is selected for a CMV-seronegative patient. For a CMV-seropositive patient, our data support selecting a CMV-seropositive donor if the patient receives a myeloablative conditioning regimen. © The Author 2014.

    Gene therapy (GT) for adenosine deaminase–deficient severe combined immune deficiency (ADA-SCID) can provide significant long-term benefit when patients are given nonmyeloablative conditioning and ADA enzyme-replacement therapy (ERT) is withheld before autologous transplantation of γ-retroviral vector-transduced BM CD34+ cells. To determine the contributions of conditioning and discontinuation of ERT to the therapeutic effects, we analyzed these factors in Ada gene knockout mice (Ada−/−). Mice were transplanted with ADA-deficient marrow transduced with an ADA-expressing γ-retroviral vector without preconditioning or after 200 cGy or 900 cGy total-body irradiation and evaluated after 4 months. In all tissues analyzed, vector copy numbers (VCNs) were 100- to 1000-fold greater in mice receiving 900 cGy compared with 200 cGy (P < .05). In mice receiving 200 cGy, VCN was similar whether ERT was stopped or given for 1 or 4 months after GT. In unconditioned mice, there was decreased survival with and without ERT, and VCN was very low to undetectable. When recipients were conditioned with 200 cGy and received transduced lineage-depleted marrow, only recipients receiving ERT (1 or 4 months) had detectable vector sequences in thymocytes. In conclusion, cytoreduction is important for the engraftment of gene-transduced HSC, and short-term ERT after GT did not diminish the capacity of gene-corrected cells to engraft and persist.

    Oral mucositis is a severe and dose limiting early side effect of radiotherapy for head-and-neck tumors. This study was initiated to determine the effect of bone marrow- and mesenchymal stem cell transplantation on oral mucositis (mouse tongue model) induced by fractionated irradiation. Daily fractionated irradiation (5 x 3 Gy/week) was given over 1 (days 0-4) or 3 weeks (days 0-4, 7-11, 14-18). Each protocol was terminated (day 7 or 21) by graded test doses (5 dose groups, 10 animals each) in order to generate complete dose-effect curves. The incidence of mucosal ulceration, corresponding to confluent mucositis grade 3 (RTOG/EORTC), was analyzed as the primary, clinically relevant endpoint. Bone marrow or mesenchymal stem cells were transplanted intravenously at various time points within these fractionation protocols. Transplantation of 6 x 10 6 , but not of 3 x 10 6 bone marrow stem cells on day -1, +4, +8, +11 or +15 significantly increased the ED 50 values (dose, at which an ulcer is expected in 50% of the mice); transplantation on day +2, in contrast, was ineffective. Mesenchymal stem cell transplantation on day -1, 2 or +8 significantly, and on day +4 marginally increased the ED 50 values. Transplantation of bone marrow or mesenchymal stem cells has the potential to modulate radiation-induced oral mucositis during fractionated radiotherapy. The effect is dependent on the timing of the transplantation. The mechanisms require further investigation. (orig.)

    To analyze clinical outcomes and the risk factors associated with genitourinary (GU) morbidity and mortality in children who present with hemorrhagic cystitis (HC) after bone marrow transplant (BMT). A retrospective chart review of patients with HC who had undergone BMT at a single pediatric hospital from 2008 to 2015 was conducted. Demographic data, severity of hematuria, HC management, and mortality were analyzed. Bivariate analysis and binary logistic regression were performed to identify risk factors. Out of 43 patients who met inclusion criteria, 67.4% were male with a median age at BMT of 10.2 years (interquartile range 5.8-14.6). Percutaneous nephrostomy catheters were inserted in 5 patients for urinary diversion. All-cause mortality was 32.6% (N = 14). Intravesical retroviral therapy (P hematuria time (P hematuria (P = .032) were associated with significant GU morbidity on bivariate analysis. On multivariable analysis, days to most improved hematuria was associated with significant GU morbidity odds ratio of 1.177 (1.006-1.376) (P = .042). Status of percutaneous nephrostomy was not associated with increased mortality (P = .472); however, in the multivariate model, BK viremia (P = .023), need for renal dialysis (P = .003), and presence of Foley catheter (P = .005) were associated with increased mortality. Children with HC after BMT fall in a very high-risk category with high mortality and significant GU morbidity. The presence of a Foley catheter, need for dialysis, and BK viremia are associated with increased mortality. Copyright © 2016 Elsevier Inc. All rights reserved.

    In an attempt to improve survival while minimizing toxicity, many bone marrow transplant centers are now studying the use of cytoreduction regimens with an increased amount of radiation in single-dose or fractionated-exposure schedules for patients with leukemia and aplastic anemia. In order to review the current results, the literature prior to September, 1982 was surveyed and data were tabulated for each transplant center regarding the number of patients receiving transplants, diagnoses, cytoreduction regimen, clinical status, remission duration, relapse rate, causes of death and incidence of interstitial pneumonia. The incidence and severity of cataracts, growth failure, hypothyroidism and second malignant neoplasms were noted, and the data obtained from the literature search were updated and expanded by telephone questionnaire when possible. Marked variation in the technique of tranplantation was found among the participating institutions, making it difficult to determine the contribution of the various TBI doses, dose rates and fractionation schedules to the efficacy and toxicity of the combined regimen. In order to define the risk-benefit ratio of the various TBI regimens more clearly, prospective controlled, randomized studies will be required

    Purpose: To determine the acute and late effects, including cognitive function, of total body irradiation (TBI) and chemotherapy for bone marrow transplant (BMT) in children with immunodeficiency or hematologic disorders. Methods and Materials: At UCSF, 15 children with immunodeficiency disorders and 58 children with leukemia received chemoradiotherapy between July 1982 and November 1993 and were evaluated for toxicity. Patients with severe combined immunodeficiency disorder (SCID) received 7 Gy TBI while leukemia patients received 12 Gy TBI. Results: Eight immunodeficient patients (53%) are alive at 4 months to 11 years posttransplant. Acute toxicity was limited and treatment well tolerated. Most patients developed mild nausea and vomiting, skin rash, or erythema. Transient fever/chills, oral mucositis, and alopecia were noted in approximately 50% of patients. Seventy-three percent of patients demonstrated acute liver dysfunction, but only four (27%) developed veno-occlusive disease. All children had decreased growth velocity but normal growth hormone levels. Other endocrinologic evaluations including adrenocorticotropic hormone (ACTH), cortisol, and thyroid hormones were normal. Only one evaluable girl had delayed puberty with late onset of secondary sexual characteristics. Neuropsychological testing demonstrated an intelligence quotient (IQ) reduction between the baseline and 1 year post-BMT, with some recovery at 3 years. Only one patient developed a clinically significant cataract. Thirteen percent of patients had chronic interstitial lung disease. Four children developed exostosis. Only 1 of the 15 children developed a second malignancy (acute myelogenous leukemia) at age 5, 51 months posttransplant for SCID. For patients with leukemia, similar toxicities were observed. Twenty-nine percent disease-free survival was noted with a mean follow-up of 4.7 years. Twenty-two percent had chronic interstitial lung disease and two patients were diagnosed with cataracts

    In previous studies, transplantation of bone marrow mononuclear cells (BMMCs) in epileptic animals has been found to be neuroprotective. However, the mechanism by which the BMMCs act remains unclear. We hypothesize that BMMCs may provide neuroprotection to the epileptic brain through trophic support. To test our hypothesis, we studied the temporal expression of neurotrophins after BMMC transplantation in the epileptic rat hippocampus. Chronically epileptic rats were intravenously transplanted with 1 × 10(7) BMMCs isolated from GFP transgenic mice. Expression levels of BDNF, GDNF, NGF, VEGF, and TGF-β1, and their receptors, were evaluated by ELISA and/or qRT-PCR analysis. Our data revealed increased protein expression of BDNF, GDNF, NGF, and VEGF and reduced levels of TGF-β1 in the hippocampus of transplanted epileptic animals. Additionally, an increase in the mRNA expression of BDNF, GDNF, and VEGF, a reduction in TGF-β1, and a decrease in mRNA levels of the TrkA and TGFR-β1 receptors were also observed. The gain provided by transplanted BMMCs in the epileptic brain may be related to the ability of these cells in modulating the network of neurotrophins and angiogenic signals. © 2015 John Wiley & Sons Ltd.

Behavior was explored using motor (beam test and memory (object recognition and Morris water maze tests. Morphology was evaluated using conventional histology (cresyl violet, bisbenzimide (to evaluate cell vitality, and immunohystochemistry to identify neurons or glia. mBMC-transplanted animals showed improvements in motor coordination (beam test. Regarding memory, object recognition was significantly improved in transplanted animals, while spatial memory (Morris water maze test was not severely affected by QA and, therefore, the results after transplantation were significant only in the probe-trial retention test. In samples taken from the animals that participated in the behavioral tests, a preserved morphology of striatal neurons and a reduced glial reaction indicated a possible neuroprotective effect of the transplanted mBMCs. A parallel study confirmed that the transplanted mBMCs have a long survival period (1 year follow-up. The results presented confirm the possibility that mBMC transplantation may be a viable therapeutic option for Huntington’s disease.

    Objective: To establish the model of graft-versus-host disease (GVHD) in mice with allogeneic bone marrow transplantation. Methods: Bone marrow cells were combined with spleen cells of male donor C57BL/6 mice according to different proportions, then were transfused into female postradiation recipient BALB/c mice. General state, life span and histopathology of the recipient mice and detected chimera were observed. Results and Conclusion:The recipient mice groups which accepted above 5 x 10 6 donor spleen cells developed acute GVHD after different peroids of time. The GVHD model in mice after allo-BMT was successfully established. The transfusion of 5 x 10 6 -5 x 10 7 spleen cells may be adequate to establish the murine model of GVHD for the prevention and treatment of GVHD. The number of murine spleen cells can be chosen according to the experimental requirement. (authors)

    Objective: To evaluate the feasibility of treatment for rabbit model with hepatic cirrhosis by transplantation of autologous bone marrow-derived stem cells via the hepatic artery and evaluate the effect of hepatocyte growth-promoting factors (pHGF) in the treatment of stem cells transplantation to liver cirrhosis. To provide empirical study foundation for future clinical application. Methods: Chronic hepatic cirrhosis models of rabbits were developed by subcutaneous injection with 50% CCl 4 0.2 ml/kg. Twenty-five model rabbits were randomly divided into three experimental groups, stem cells transplant group (10), stem cells transplant + pHGF group (10) and control group (5). Autologous bone marrow was harvested from fibia of each rabbit, and stem cells were disassociated using density gradient centrifugation and transplanted into liver via the hepatic artery under fluoroscopic guidance. In the stem cells transplant + pHGF group, the hepatocyte growth-promoting factor was given via intravenous injection with 2 mg/kg every other day for 20 days. Liver function tests were monitored at 4, 8,12 weeks intervals and histopathologic examinations were performed at 12 weeks following transplantation. The data were analyzed using analysis of variance Results: Following transplantation of stern cells, the liver function of rabbits improved gradually. Twelve weeks after transplantation, the activity of ALT and AST decreased from (73.0±10.6) U/L and (152.4± 22.8) U/L to (48.0±1.0) U/L and (86.7±2.1) U/L respectively; and the level of ALB and PTA increased from (27.5±1.8) g/L and 28.3% to (33.2±0.5) g/L and 44.1% respectively. The changes did not have statistically significant difference when compared to the control group (P>0.05). However, in the stem cellstransplant + pHGF group, the activity of ALT and AST decreased to (43.3±0.6) U/L and (78.7±4.0) U/L respectively and the level of ALB and PTA increased to (35.7±0.4) g/L and 50.5% respectively.

    A preparative regimen for allogeneic bone marrow transplantation, consisting of total lymphoid irradiation (TLI) with 750 cGy and cyclophosphamide (CY), was used in five girls with aplastic anemia. All patients received bone marrow from HLA matched/mixed lymphocyte culture negative siblings. In our regimen the 'inverted Y' field to irradiate the pelvic nodes was modified, which did not include the whole pelvic cavity in an attempt to protect the ovaries from irradiation. Although some of the pelvic nodes was supported not to be irradiated in order to protect the ovaries, engraftment occurred in all five patients including four who had been transfused prior to transplantation. All five are alive from 47 days to 1378 days (median 285 days) after transplantation without tranplantation-associated complications. The calculated dose to the ovaries was sixteen percent of the entire dose of the regimen. Both of the two evaluable patients that had received tranplantation just before or during the puberty are developing normal sex maturity including menstruation. This study suggests that our preparative regimen is effective not only for engraftment of the donor marrow but also for protecting the ovaries from irradiation. (author).

    Internalizing quantum dots (i-QDs) are a useful tool for tracking cells in vivo in models of tissue regeneration. We previously synthesized i-QDs by conjugating QDs with a unique internalizing antibody against a heat shock protein 70 family stress chaperone. In the present study, i-QDs were used to label rabbit mesenchymal stromal cells (MSCs) that were then transplanted into rabbits to assess differentiation potential in an osteonecrosis model. The i-QDs were taken up by bone marrow-derived MSCs collected from the iliac of 12-week-old Japanese white rabbits that were positive for cluster of differentiation (CD)81 and negative for CD34 and human leukocyte antigen DR. The average rate of i-QD internalization was 93.3%. At 4, 8, 12, and 24 weeks after transplantation, tissue repair was evaluated histologically and by epifluorescence and electron microscopy. The i-QDs were detected at the margins of the drill holes and in the necrotized bone trabecular. There was significant colocalization of the i-QD signal in transplanted cells and markers of osteoblast and mineralization at 4, 8, and 12 weeks post-transplantation, while i-QDs were detected in areas of mineralization at 12 and 24 weeks post-transplantation. Moreover, i-QDs were observed in osteoblasts in regenerated tissue by electron microscopy, demonstrating that the tissue was derived from transplanted cells. These results indicate that transplanted MSCs can differentiate into osteoblasts and induce tissue repair in an osteonecrosis model and can be tracked over the long term by i-QD labeling.

    Patients with chronic lymphocytic leukemia (CLL) and 17p deletion (17p-) have a poor prognosis. Although allogeneic hematopoietic stem-cell transplantation (HCT) has the potential to cure patients with advanced CLL, it is not known whether this holds true for patients with 17p-CLL. Baseline data from patients, for whom information on the presence of 17p-CLL was available, were downloaded from the European Group for Blood and Marrow Transplantation database. Additional information on the course of CLL and follow-up was collected with a questionnaire. A total of 44 patients with 17p-CLL received allogeneic HCT between March 1995 and July 2006 from a matched sibling (n = 24) or an alternative donor (n = 20). 17p-CLL had been diagnosed by fluorescent in situ hybridization in 82% of patients and by conventional banding in 18% of patients. The median age was 54 years. Before HCT, a median of three lines of chemotherapy had been administered. At HCT, 53% of patients were in remission. Reduced-intensity conditioning was applied in 89% of patients. Acute, grade 2 to 4 graft-versus-host disease (GVHD) occurred in 43% of patients, and extensive chronic GVHD occurred in 53% of patients. At last follow-up, 19 patients were alive, with a median observation time of 39 months (range, 18 to 101 months). Three-year overall survival and progression-free survival rates were 44% and 37%, respectively. The cumulative incidence of progressive disease at 4 years was 34%. No late relapse occurred in nine patients with a follow-up longer than 4 years. Allogeneic HCT has the potential to induce long-term disease-free survival in patients with 17p-CLL.

    Objective: To develop a new method of bone marrow scheduled transplantation (BMST) by making use of the effects of acidic fibroblast growth factor (aFGF) on improving hematopoiesis. Methods: The scheduled transplantation of bone marrow cells preincubated with aFGF (aFGF-BMST) was carried out to study the effects of aFGF on hematopoietic reconstitution and reducing acute graft versus host disease (GVHD) in acute radiation disease model of Kunming mice. Results: The survival rate of the group of aFGF-BMST mice with 4 x 10 6 BMXs was 40%, which was higher than the survival of the group of BMT with 1 x 10 7 BMCs alone (30%), but was lower than the survival of the group of BMST with 4 x 10 6 BMCs. On the other hand, the recovery rates in numbers of leucocytes, nucleated cells and CFU-E, CFU-GM, CFU-S were faster than those in the group of BMT with 1 x 10 7 BMCs alone and in the group of BMST with 4 x 10 6 BMCs. In addition, the severity of GVHD in the group of aFGF-BMST mice with 4 x 10 6 BMCs was lower than that in the group of BMT with 1 x 10 7 BMCs alone but was higher than that in the group of BMST with 4 x 10 6 BMCs. Conclusion: Although aFGF can activate heterogeneous T cells to cause GVHD, there is prospect of making full use of the effects of aFGF on improving hematopoiesis and reducing the side effects of aFGF leading to GVHD through scheduled transplantation of bone marrow cells preincubated with aFGF

  14. Selection of unrelated donors for bone marrow transplantation studied in rhesus monkeys

    Wagemaker, G.; Bekkum, D.W. van

    Graft versus Host disease (GvHD) remains to be a severe limitation to a more general application of bone marrow transplantation. Clinically acceptable results are restricted to those potential recipients for which a major histocompatibility complex (MHC) identical sibling donor is available. At an average family size of 2 to 3 siblings, the frequency of such donors is not more than approximately 30%. This pre-clinical study in rhesus monkeys is directed at the selection of donors for recipients which lack an MHC identical sibling. (Auth.)

    Full Text Available Thalassemia is among the most frequent indications for preimplantation genetic diagnosis (PGD to allow at risk couples reproducing without fear of having an affected child. In addition, those already having the affected child, have also the option to produce an unaffected offspring that may be also a complete human leukocyte antigen (HLA match to affected child to ensure successful bone marrow transplantation. We present here the results of retrospective analysis of 293 PGD cycles for thalassemia, including 144cases of simultaneous HLA typing, resulting in birth of 70 thalassemia-free children and 12 unaffected HLA matched ones, providing their cord blood and/or bone marrow for transplantation treatment of their affected siblings. The present overall experience includes successful cord blood or bone marrow transplantation in more than three dozens of cases with HLA matched stem cells obtained from children born after PGD, demonstrating that PGD is an efficient approach for improving success of bone marrow transplantation treatment for thalassemia.   植入前遗传学诊断(PGD)是地中海贫血(地贫)最常用的疗法,该病患者夫妇无须担心孕儿受到感染。此外,如果已经怀上受到感染的宝宝,他们也可有选择性再生育一个未受感染的后代,提供完全匹配的HLA,来确保骨髓成功移植。本文将提供293个地贫病例的PGD周期诊断结果,包括144例HLA同时配型,有70例宝宝无地贫出生和12例未受感染的HLA配型宝宝出生。将这些健康宝宝的脐带血和/或骨髓取出以完成对他们同胞的移植手术,通过使用经诊断后的,出生宝宝身上取出的HLA配型干细胞,成功完成36例宝宝的脐带或骨髓移植手术。结果表明PGD能有效提高地贫患儿骨髓移植手术的成功率。

    Histoincompatible bone marrow allografts were established in lethally irradiated rats. At various times after transplantation, the spleen cells were harvested, subjected to mixed lymphocyte cultures, and assayed for suppressor cells in vitro and in vivo by adoptive transfer studies. Alloantigen-nonspecific suppressor cells appeared in the chimera at 40 days after grafting, coinciding with the resolution of graft-versus-host disease (GVHD). At 250 days the nonspecific suppressor cells were replaced by suppressor cells specifically suppressing donor-versus-host alloantigen responses. At 720 days suppressor cells could no longer be identified by in vitro methods but were identified by in vivo adoptive transfer of transplantation tolerance. After injection of host-type antigen into chimeras, the suppressor cells could be again demonstrated by in vitro methods

  19. Transplant tourism among kidney transplant patients in Eastern Nigeria.

    Okafor, U H

    2017-07-05

    Transplant tourism entails movement of recipient, donor or both to a transplant centre outside their country of residence. This has been reported in many countries; and has variously been associated with organ trade. The objective of this study is to determine the frequency and pattern of transplant tourism among transplant patients in Eastern Nigeria. This is a non randomized cross sectional study. All kidney transplant patients who presented at Enugu State University Teaching Hospital Parklane Enugu and Hilton Clinics Port Harcourt in Nigeria were recruited. The clinical parameters including the transplant details of all the patients were documented. The data obtained was analysed using SPSS package. A total of one hundred and twenty six patients were studied, 76.2% were males with M:F ratio of 3.2:1 and mean age of 46.9 ± 13.3 years. Fifty four and 58.7% of the patients were managed in a tertiary hospital and by a nephrologist respectively before referral for kidney transplant. Only 15.8% of the patients had their kidney transplant without delay: finance, lack of donor, logistics including delay in obtaining travelling documents were the common causes of the delay. Ninety percent of the patients had their transplant in India with majority of them using commercial donors. India was also the country with cheapest cost ($18,000.00). 69.8% were unrelated donors, 68.2% were commercial donors and 1.6% of the donors were spouse. All the commercial donors received financial incentives and each commercial donor received mean of 7580 ± 1280 dollars. Also 30.2% of the related donors demanded financial incentive. Transplant tourism is prevalent in eastern Nigeria.

  20. Central venous access through the external jugular vein in children submitted to bone marrow transplantation

    2005-01-01

    Full Text Available Establishment of long-term central venous access is a sine qua non step for bone marrow transplantation in children. Most frequently, long-term central venous access has been obtained via blind percutaneous cannulation of subclavian and internal jugular veins or via internal jugular vein cutdown. In order to avoid some potential minor and major complications associated with the subclavian or internal jugular approaches, the authors describe an easy, simple and safe method for central venous access through an external jugular vein cutdown that should be of interest to readers involved in the field of bone marrow transplantation. It should be also considered for children as well as adults needing central venous access via an external catheter - or totally implantable port - for reasons other than bone marrow transplantation, such as total parenteral nutrition and administration of chemotherapeutic agents.O estabelecimento de um acesso venoso central de longa duração é uma condição sine qua non para realizar o transplante de medula óssea em crianças. Com frequência, este acesso tem sido obtido através da punção percutânea das veias subclávia e jugular interna ou via dissecção da jugular interna. Com o objetivo de evitar algumas complicações maiores e menores associadas com a subclávia e a jugular interna, os autores descrevem um método simples, fácil e seguro para o acesso venoso central através de dissecção da veia jugular externa. Este método deveria ser de interesse dos leitores envolvidos com o transplante de medula óssea e ser considerado também para crianças e/ou adultos que necessitem de cateter venoso central de longa permanência (externo ou totalmente implantável devido a outras razões, como a nutrição parenteral ou a administração de agentes quimioterápicos.

    Long-term results regarding treatment of chronic ischemic heart failure with bone marrow mononuclear cells (BMMCs) have been few. We received encouraging results at the 1-year follow-up of patients treated with combined coronary artery bypass grafting (CABG) and BMMCs, so we decided to extend the follow-up. The study patients had received injections of BMMCs or vehicle into the myocardial infarction border area during CABG in a randomized and double-blind manner. We could contact 36 of the 39 patients recruited for the original study. Pre-operatively and after an extended follow-up period, we performed magnetic resonance imaging, measured pro-B-type amino-terminal natriuretic peptide, reviewed patient records from the follow-up period, and determined current quality of life with the Medical Outcomes Study Short-Form 36 (SF-36) Health Survey. The median follow-up time was 60.7 months (interquartile range [IQR], 45.1-72.6 months). No statistically significant difference was detected in change of pro-B-type amino-terminal natriuretic peptide values or in quality of life between groups. The median change in left ventricular ejection fraction was 4.9% (IQR, -2.1% to 12.3%) for controls and 3.9% (IQR, -5.2% to 10.2%) for the BMMC group (p = 0.647). Wall thickening in injected segments increased by a median of 17% (IQR, -5% to 30%) for controls and 15% (IQR, -12% to 19%) for BMMC patients (p = 0.434). Scar size in injected segments increased by a median of 2% (IQR, -7% to 19%) for controls but diminished for BMMC patients, with a median change of -17% (IQR, -30% to -6%; p = 0.011). In the treatment of chronic ischemic heart failure, combining intramyocardial BMMC therapy with CABG fails to affect cardiac function but can sustainably reduce scar size, even in the long-term.

  3. Relações entre a personalidade dos pacientes e a sobrevivência após o transplante de medula óssea: revisão da literatura Linkings between patients' personality and bone marrow transplant survival: bibliographical review

    Rodrigo Sanches Peres

    2006-08-01

    mantenimiento del bienestar biopsicosocial de esos sujetos.Bone marrow transplant (BMT is a medical procedure used in case of serious illness treatment, that is, when the conventional therapeutic modalities do not offer a good prognostic. Recent researches suggest that, the patients' personality is a decisive psychosocial factor for adaptation and recovery after BMT procedure. The present paper intends to evaluate the scientific productions regarding the patients' personality and its relation to post-BMT survival. Data collection was carried out by using on-line searches in the different bibliographical identification systems available. The results obtained suggest the need for new researches, because understanding the relation between the patients' personality and the post-BMT survival can aid the individual/patient in both, in the prevention, as well as in the maintenance of the bio-psychosocial well being.

    The transplantation of bone marrow (BM) derived cells to initiate pancreatic regeneration is an attractive but as-yet unrealized strategy. Presently, BM derived cells from green fluorescent protein transgenic mice were transplanted into diabetic mice. Repair of diabetic islets was evidenced by reduction of hyperglycemia, increase in number of islets, and altered pancreatic histology. Cells in the pancreata of recipient mice co-expressed BrdU and insulin. Double staining revealed β cells were in the process of proliferation. BrdU + insulin - PDX-1 + cells, Ngn3 + cells and insulin + glucagon + cells, which showed stem cells, were also found during β-cell regeneration. The majority of transplanted cells were mobilized to the islet and ductal regions. In recipient pancreas, transplanted cells simultaneously expressed CD34 but did not express insulin, PDX-1, Ngn3, Nkx2.2, Nkx6.1, Pax4, Pax6, and CD45. It is concluded that BM derived cells especially CD34 + cells can promote repair of pancreatic islets. Moreover, both proliferation of β cells and differentiation of pancreatic stem cells contribute to the regeneration of β cells

    The purpose of this study was to examine coagulase-negative staphylococcal infections in bone marrow transplantation (BMT) patients with central vein catheters by investigating incidence, clinical relevance, risk factors, methicillin resistance, clinical impact of initial empiric antimicrobial therapy without vancomycin, and management of documented catheter-related infections. A 5-year prospective study was conducted with daily evaluation of 242 BMT patients during hospitalization, including clinical assessment and blood culture via the Hickman/Broviac catheter. If fever or infected appearance occurred, peripheral blood cultures or exit site cultures, respectively, were done. Results showed a septicemia incidence of 7.0%, including in 6 patients following colonization, in 1 patient with tunnel infection, in 1 patient with thrombophlebitis, in 1 patient with exit site infection, and in 8 patients with septicemia of unknown origin. Total colonization incidence was 7%, with colonization only in 11 patients who had 16 episodes; incidence of exit site infection was 3.7%. Age > or = 18 years was the only identified risk factor for developing staphylococcal infection (P = 0.03). Despite a methicillin resistance rate of 45% and omission of vancomycin from the routine initial empiric antimicrobial regimen, the clinical course of coagulase-negative staphylococcal infections was relatively benign. A single patient, who experienced marrow rejection, died on day +31 with septicemia and only one patient experienced microbiological failure with recurrent colonization. Bacteria grown in both aerobic and anaerobic bottles were more likely true bacteremia than contaminant (P = 0.03). We conclude that the hazard of coagulase-negative staphylococcal infection does not mandate inclusion of a glycopeptide in the initial empiric antimicrobial regimen in BMT patients, even during febrile neutropenia. Hickman/Broviac-related staphylococcal infections, except for tunnel infection or

    1988-01-01

    Sequential appearance of the expression of T cell antigen receptor genes was investigated in the thymus of irradiated mice at the early stage after transplantation of Thy-1 congeneic H-2 compatible allogeneic bone marrow cells. The first cells to repopulate the thymus on day 7 after bone marrow transplantation were intrathymic radioresistant T cell precursors, which expanded mainly to CD4+CD8+ host-type thymocytes by day 14. A high level of gamma gene expression but a much reduced level of alpha and beta gene expression were detected in the host-type thymocytes on day 7. During regeneration of these cells, gamma-chain messages fell to low level and alpha and beta mRNA levels increased. The thymus of the recipients began to be repopulated by donor-derived T cells about 2 wk after bone marrow transplantation and was almost completely replaced by the third week. An ordered expression of gamma then beta and alpha-chain gene transcript was also observed in the donor-type thymocytes at the early stage after bone marrow transplantation. The use of thymocytes at early stage in whole-body irradiated bone marrow chimera provides a pertinent source for investigating the molecular mechanism of T cell differentiation in adult thymus

  7. Constant post-irradiation repopulation rates and linear relationship between cellular blood response and number of transplanted bone marrow cells in inbread mice

    Petersen, B.H.

    1977-01-01

    Graded doses of syngeneic bone marrow cells were transplanted into lethally irradiated mice. Repopulation curves of peripheral blood granulocytes and platelets were apparently exponential and parallel after doses larger than 5 x 10 5 cells. The blood platelet sub(d) was reduced from 111 h to 53-57 h, and granulocyte Tsub(d) from 57 to 40 h in transplanted groups. The mean blood cell counts were reproducible to be used as a biological assay of the amount of bone marrow cells transplanted. Linear relationship between increment of blood cells up to day 16 and number of bone marrow cells transplanted on day 1 was demonstrated (1,200 granulocytes and 14,300 platelets/μl blood per 10 5 bone marrow cells). The linearity suggested a mean Tsub(d) < 22.5 h of proliferating bone marrow cells, and allowed a rough estimation of mouse bone marrow stem cell radiosensitivity (Dsub(o) 76 rad). (author)

    Mesenchymal stem cells (MSCs) are multipotent cells that can be isolated from human bone marrow and possess the potential to differentiate into progenies of embryonic mesoderm. However, current evidence is based predominantly on in vitro experiments. We used a murine model of in utero transplantation (IUT) to study the engraftment capabilities of human MSCs. MSCs were obtained from bone marrow by negative immunoselection and limiting dilution, and were characterized by flow cytometry and by in vitro differentiation into osteoblasts, chondrocytes, and adipocytes. MSCs were transplanted into fetal mice at a gestational age of 14 days. Engraftment of human MSCs was determined by flow cytometry, polymerase chain reaction, and fluorescence in situ hybridization (FISH). MSCs engrafted into tissues originating from all three germ layers and persisted for up to 4 months or more after delivery, as evidenced by the expression of the human-specific beta-2 microglobulin gene and by FISH for donor-derived cells. Donor-derived CD45+ cells were detectable in the peripheral blood of recipients, suggesting the participation of MSCs in hematopoiesis at the fetal stage. This model can further serve to evaluate possible applications of MSCs. Copyright 2006 Orthopaedic Research Society.

    Until now, there has been no effective therapy for chronic sensorineural hearing impairment. This study investigated the role of bone marrow cells (BMCs) in cochlear dysfunction. BALB/c mice (2 months of age), a non-presbycusis-prone mouse strain, were lethally irradiated and then transplanted with BMCs from SAMP1 mice (2 months of age), a presbycusis-prone mouse strain. Acceleration of age-related hearing loss, early degeneration of spiral ganglion cells (SGCs) and impairment of immune function were observed in the recipient mice as well as in the SAMP1 mice. However, no spiral ganglion cells of donor (SAMP1) origin were detected in the recipient mice. These results indicated that accelerated presbycusis, cochlear pathology, and immune dysfunction of SAMP1 mice can be transferred to BALB/c recipient mice using allogeneic bone marrow transplantation (BMT). However, although the BMCs themselves cannot differentiate into the spiral ganglion cells (SGCs), they indirectly cause the degeneration of the SGCs. Further studies into the relationship between the inner ear cells and BMCs are required.

  10. Effect of intravenous transplantation of bone marrow mesenchymal stem cells on neurotransmitters and synapsins in rats with spinal cord injury

    2012-01-01

    Bone marrow mesenchymal stem cells were isolated, purified and cultured in vitro by Percoll density gradient centrifugation combined with the cell adherence method. Passages 3–5 bone marrow mesenchymal stem cells were transplanted into rats with traumatic spinal cord injury via the caudal vein. Basso-Beattie-Bresnahan scores indicate that neurological function of experimental rats was significantly improved over transplantation time (1–5 weeks). Expressions of choline acetyltransferase, glutamic acid decarboxylase and synapsins in the damaged spinal cord of rats was significantly increased after transplantation, determined by immunofluorescence staining and laser confocal scanning microscopy. Bone marrow mesenchymal stem cells that had migrated into the damaged area of rats in the experimental group began to express choline acetyltransferase, glutamic acid decarboxylase and synapsins, 3 weeks after transplantation. The Basso-Beattie- Bresnahan scores positively correlated with expression of choline acetyltransferase and synapsins. Experimental findings indicate that intravenously transplanted bone marrow mesenchymal stem cells traverse into the damaged spinal cord of rats, promote expression of choline acetyltransferase, glutamic acid decarboxylase and synapsins, and improve nerve function in rats with spinal cord injury.

    Objective: To evaluate the clinical value of bone marrow mesenchymal stem cell transplantation on acute myocardial infarction in pig with myocardial perfusion imaging. Methods: Acute myocardial infarction models were established by 21 minitype Chinese pigs and were divided into two groups. After 10 days, experimental group (n=11) was transplanted with bone marrow mesenchymal stem cell at the infarct areas, and the control group (n=10) with incubation solution. Before and eight weeks after transplantation, both groups were examined by 99 Tc m -methoxyisobutylisonitrile (MIBI) myocardial perfusion imaging and with semi-quantitative analysis. Besides, echocardiogram and immunohistochemistry were also performed. Results: There was significant difference of total myocardial perfusion abnormal segments (46 vs 26), infarct areas [(34±12)% vs (21±10)%] and myocardial ischemia score [(20.0±4.3) vs (12.1±3.6)] between two groups (P<0.05). Also, there were accordant results with echocardiogram and immunohistochemistry findings. Conclusions: Bone marrow mesenchymal stem cell transplantation may improve blood perfusion and viability of the ischemic areas: Myocardial perfusion imaging can accurately observe the survival of bone marrow mesenchymal stem cell transplanted at the infarct areas.

    The best treatment approach for children with B-precursor acute lymphoblastic leukemia (ALL) in second clinical remission (CR) after a marrow relapse is controversial. To address this question, we compared outcomes in 188 patients enrolled in chemotherapy trials and 186 HLA-matched sibling transplants, treated between 1991 and 1997. Groups were similar except that chemotherapy recipients were younger (median age, 5 versus 8 years) and less likely to have combined marrow and extramedullary relapse (19% versus 30%). To adjust for time-to-transplant bias, treatment outcomes were compared using left-truncated Cox regression models. The relative efficacy of chemotherapy and transplantation depended on time from diagnosis to first relapse and the transplant conditioning regimen used. For children with early first relapse (children with a late first relapse (> or = 36 months), risks of second relapse were similar after TBI-containing regimens and chemotherapy (RR, 0.92; 95% CI, 0.49-1.70, P = .78). These data support HLA-matched sibling donor transplantation using a TBI-containing regimen in second CR for children with ALL and early relapse.

    Frontotemporal dementia (FTD) is a neurodegenerative disease with devastating changes in behavioral performance and social function. Mutations in the progranulin gene (GRN) are one of the most common causes of inherited FTD due to reduced progranulin expression or activity, including in brain where it is expressed primarily by neurons and microglia. Thus, efforts aimed at enhancing progranulin levels might be a promising therapeutic strategy. Bone marrow-derived cells are able to engraft in the brain and adopt a microglial phenotype under myeloablative irradiation conditioning. This ability makes bone marrow (BM)-derived cells a potential cellular vehicle for transferring therapeutic molecules to the central nervous system. Here, we utilized BM cells from Grn+/+ (wild type or wt) mice labeled with green fluorescence protein for delivery of progranulin to progranulin deficient (Grn−/−) mice. Our results showed that wt bone marrow transplantation (BMT) partially reconstituted progranulin in the periphery and in cerebral cortex of Grn−/− mice. We demonstrated a pro-inflammatory effect in vivo and in ex vivo preparations of cerebral cortex of Grn−/− mice that was partially to fully reversed five months after BMT. Our findings suggest that BMT can be administered as a stem cell-based approach to prevent or to treat neurodegenerative diseases. PMID:25199051

    1993-01-01

    The role of total body irradiation (TBI) for allogeneic bone marrow transplantation (BMT) for acute leukemia in first complete remission was reevaluated in this study. From Japanese BMT Registry, data of 123 acute leukemia patients in first complete remission who underwent allogeneic bone marrow transplantation in 22 hospitals between 1988 and 1990 were available for the present comparative study of preparation regimens with or without total body irradiation. Two-year survivals were 77% and 51% in the TBI containing regimen group and in the non-TBI regimen group, respectively (p=0.0010). Corresponding two-year relapse rates were 16% and 37%, respectively (p=0.0197). Corresponding probabilities of developing interstitial pneumonitis were 21% and 24%, respectively (p=0.8127). The analysis of causes of death indicated that non-TBI regimen increased the incidence of septicemia and lethal organ failures, such as liver, heart, lung and other multiple sites. It was emphasized that an additional role of total body irradiation was to disperse the treatment-related toxicity in allogeneic bone marrow transplantation for acute leukemia. (orig.) [de

    Full Text Available Background: Steady-state bone marrow (SS-BM and granulocyte colony-stimulating growth factor-primed BM/peripheral blood stem-cell (G-BM/G-PBSC are the main stem-cell sources used in allogeneic hematopoietic stem-cell transplantation. Here, we evaluated the treatment effects of SS-BM and G-BM/G-PBSC in human leucocyte antigen (HLA-identical sibling transplantation. Methods: A total of 226 patients (acute myelogenous leukemia-complete remission 1, chronic myelogenous leukemia-chronic phase 1 received SS-BM, G-BM, or G-PBSC from an HLA-identical sibling. Clinical outcomes (graft-versus-host disease [GVHD], overall survival, transplant-related mortality [TRM], and leukemia-free survival [LFS] were analyzed. Results: When compared to SS-BM, G-BM gave faster recovery time to neutrophil or platelet (P 0.05. Conclusions: G-CSF-primed bone marrow shared the advantages of G-PBSC and SS-BM. We conclude that G-BM is an excellent stem-cell source that may be preferable to G-PBSC or SS-BM in patients receiving HLA-identical sibling hematopoietic stem-cell transplantation.

    Unrelated allogeneic transplantation for severe aplastic anemia is a treatment option after immunosuppressive treatment failure in the absence of a matched sibling donor. Age, delay between disease diagnosis and transplantation, and HLA matching are the key factors in transplantation decisions, but their combined impact on patient outcomes remains unclear. Using the French Society of Bone Marrow Transplantation and Cell Therapies registry, we analyzed all consecutive patients (n=139) who underwent a first allogeneic transplantation for idiopathic severe aplastic anemia from an unrelated donor between 2000 and 2012. In an adjusted multivariate model, age over 30 years (Hazard Ratio=2.39; P=0.011), time from diagnosis to transplantation over 12 months (Hazard Ratio=2.18; P=0.027) and the use of a 9/10 mismatched unrelated donor (Hazard Ratio=2.14; P=0.036) were independent risk factors that significantly worsened overall survival. Accordingly, we built a predictive score using these three parameters, considering patients at low (zero or one risk factors, n=94) or high (two or three risk factors, n=45) risk. High-risk patients had significantly shorter survival (Hazard Ratio=3.04; Paplastic anemia. Copyright© Ferrata Storti Foundation.

    Allogeneic hematopoietic stem-cell transplantation (HSCT) is potentially curative for acute leukemia (AL), but carries considerable risk. Machine learning algorithms, which are part of the data mining (DM) approach, may serve for transplantation-related mortality risk prediction. This work is a retrospective DM study on a cohort of 28,236 adult HSCT recipients from the AL registry of the European Group for Blood and Marrow Transplantation. The primary objective was prediction of overall mortality (OM) at 100 days after HSCT. Secondary objectives were estimation of nonrelapse mortality, leukemia-free survival, and overall survival at 2 years. Donor, recipient, and procedural characteristics were analyzed. The alternating decision tree machine learning algorithm was applied for model development on 70% of the data set and validated on the remaining data. OM prevalence at day 100 was 13.9% (n=3,936). Of the 20 variables considered, 10 were selected by the model for OM prediction, and several interactions were discovered. By using a logistic transformation function, the crude score was transformed into individual probabilities for 100-day OM (range, 3% to 68%). The model's discrimination for the primary objective performed better than the European Group for Blood and Marrow Transplantation score (area under the receiver operating characteristics curve, 0.701 v 0.646; Prisk evaluation of patients with AL before HSCT, and is available online (http://bioinfo.lnx.biu.ac.il/∼bondi/web1.html). It is presented as a continuous probabilistic score for the prediction of day 100 OM, extending prediction to 2 years. The DM method has proved useful for clinical prediction in HSCT. © 2015 by American Society of Clinical Oncology.

  18. Transplantation of neuronal-primed human bone marrow mesenchymal stem cells in hemiparkinsonian rodents.

    Melissa L M Khoo

    Full Text Available Bone marrow-derived human mesenchymal stem cells (hMSCs have shown promise in in vitro neuronal differentiation and in cellular therapy for neurodegenerative disorders, including Parkinson' disease. However, the effects of intracerebral transplantation are not well defined, and studies do not agreed on the optimal neuronal differentiation method. Here, we investigated three growth factor-based neuronal differentiation procedures (using FGF-2/EGF/PDGF/SHH/FGF-8/GDNF, and found all to be capable of eliciting an immature neural phenotype, in terms of cell morphology and gene/protein expression. The neuronal-priming (FGF-2/EGF method induced neurosphere-like formation and the highest NES and NR4A2 expression by hMSCs. Transplantation of undifferentiated and neuronal-primed hMSCs into the striatum and substantia nigra of 6-OHDA-lesioned hemiparkinsonian rats revealed transient graft survival of 7 days, despite the reported immunosuppressive properties of MSCs and cyclosporine-immunosuppression of rats. Neither differentiation of hMSCs nor induction of host neurogenesis was observed at injection sites, and hMSCs continued producing mesodermal fibronectin. Strategies for improving engraftment and differentiation post-transplantation, such as prior in vitro neuronal-priming, nigral and striatal grafting, and co-transplantation of olfactory ensheathing cells that promote neural regeneration, were unable to provide advantages. Innate inflammatory responses (Iba-1-positive microglia/macrophage and GFAP-positive astrocyte activation and accumulation were detected around grafts within 7 days. Our findings indicate that growth factor-based methods allow hMSC differentiation toward immature neuronal-like cells, and contrary to previous reports, only transient survival and engraftment of hMSCs occurs following transplantation in immunosuppressed hemiparkinsonian rats. In addition, suppression of host innate inflammatory responses may be a key factor for

    Bone marrow stromal cells (BMSC) transplantation enhances functional recovery after cerebral infarct, but the optimal delivery route is undetermined. This study was aimed to assess whether a novel cell-sheet technology non-invasively serves therapeutic benefits to ischemic stroke. First, the monolayered cell sheet was engineered by culturing rat BMSCs on a temperature-responsive dish. The cell sheet was analysed histologically and then transplanted onto the ipsilateral neocortex of rats subjected to permanent middle cerebral artery occlusion at 7 days after the insult. Their behaviours and histology were compared with those in the animals treated with direct injection of BMSCs or vehicle over 4 weeks post-transplantation. The cell sheet was 27.9 ± 8.0 μm thick and was composed of 9.8 ± 2.4 × 10 5 cells. Cell sheet transplantation significantly improved motor function when compared with the vehicle-injected animals. Histological analysis revealed that the BMSCs were densely distributed to the neocortex adjacent to the cerebral infarct and expressed neuronal phenotype in the cell sheet-transplanted animals. These findings were almost equal to those for the animals treated with direct BMSC injection. The attachment of the BMSC sheet to the brain surface did not induce reactive astrocytes in the adjacent neocortex, although direct injection of BMSCs profoundly induced reactive astrocytes around the injection site. These findings suggest that the BMSCs in cell sheets preserve their biological capacity of migration and neural differentiation. Cell-sheet technology may enhance functional recovery after ischaemic stroke, using a less invasive method. Copyright © 2014 John Wiley & Sons, Ltd. Copyright © 2014 John Wiley & Sons, Ltd.

  20. Studies on the clinical usefulness of the 111indium chloride bone marrow scintigraphy in patients with aplastic anemia

    Ino, Teruo; Ito, Naoya; Takeda, Nobuhide

    1985-01-01

    111 Indium chloride ( 111 In-Cl 3 ) appears to be a radionuclide appropriate for a bone marrow scanning because of its physical and chemical characteristics; it is, like iron, bound to and transported by transferrin and it has a photopeak suitable for scintigraphy. This study was undertaken to assess the bone marrow function by 111 In-Cl 3 bone marrow scintigraphy in patients with asplastic anemia. Bone marrow scintigraphy was performed in 21 patients with aplastic anemia with varying degrees of severity including 15 who had no previous treatments. The scintigrams were taken 48 hours after intravenous injection of 111 MBq(3 mCi) of 111 In-Cl 3 . All of them showed various degrees of reduction in uptake of 111 In-Cl 3 by the marrow. The abnormal scan grade was classified into 3 types: Type I, non-accumulation (5); Type II, low-accumulation (15); Type III, uneven accumulation (1). In type III, degree of radioisotope accumulation between the sternum and the ilium was different, and this difference correlated with that of bone marrow cellularity. In 2 patients of type II, hematological improvement occurred after treatment, which was also accompanied by simultaneous increase of 111 In-Cl 3 uptake by the marrow. These findings suggested that the degree of radioisotope accumulation in the marrow reflects that of bone marrow cellularity. Type I patients were clinically severe and poor in prognosis as compared to type II and type III patients; four out of 5 died within 2 months. Bone marrow transplantation may be the treatment of choice in type I patients when feasible. (author)

    1977-01-01

    The accumulation of /sup 99m/technetium sulfur colloid (/sup 99m/TcSC) was evaluated in 47 studies performed on 19 renal transplant patients by comparing its transplant activity to its bone marrow accumulation. There was a diagnosis of rejection in 21 of 22 studies (96.5 percent) in which marked transplant accumulation was noted. In 11 studies of patients with a clinical diagnosis of post-transplant acute tubular necrosis (ATN), the transplant activity varied from none to moderate. Rejection developed in 5 of 6 studies with minimal to moderate accumulation. Normally functioning renal transplant patients, or those with ATN and no superimposed rejection, do not show evidence of /sup 99m/TcSC accumulation

    1984-01-01

    Different groups of BALB/c mice received supralethal total-body irradiation (TBI; 8.5 Gy, day 0). When 30 x 10(6) allogeneic (C57B1) bone marrow (BM) cells were infused with or without 10 x 10(6) syngeneic (BALB/c) bM cells on day 1, many animals (60%) died from graft-versus-host disease (GVHD). Typing of peripheral blood leukocytes for donor antigens showed that, respectively, 22/22 and 17/21 of the mice in both groups became chimeric. When syngeneic bone marrow was given on day 1 and allogeneic bone marrow on day 2 after TBI, a similar number of animals (21/23) became chimeric, but GVHD occurred more frequently in this group (25/26 mice, P less than 0.01). When the syngeneic bone marrow cells were replaced by spleen cells, or when the transplantation of allogeneic bone marrow was delayed till days 3 or 6 after TBI, almost all mice rejected the allogeneic BM graft and became long-term survivors. BALB/c mice receiving 30 x 10(6) C57B1 BM cells after 17 daily fractions of 0.2 Gy of total lymphoid irradiation (TLI), showed a high incidence of chimerism (15/17) and in none of the latter animals was GVHD observed. Despite the high incidence of GVHD in the mice receiving allogeneic BM after TBI and syngeneic BM transplantation, as compared with mice prepared with TLI which do not develop GVHD, suppressor cells were as easily induced after TBI and syngeneic BM transplantation as after TLI

  3. T Cell Lymphoma and Leukemia in Severe Combined Immunodeficiency Pigs following Bone Marrow Transplantation: A Case Report

    Ellis J. Powell

    2017-07-01

    Full Text Available After the discovery of naturally occurring severe combined immunodeficiency (SCID within a selection line of pigs at Iowa State University, we found two causative mutations in the Artemis gene: haplotype 12 (ART12 and haplotype 16 (ART16. Bone marrow transplants (BMTs were performed to create genetically SCID and phenotypically immunocompetent breeding animals to establish a SCID colony for further characterization and research utilization. Of nine original BMT transfer recipients, only four achieved successful engraftment. At approximately 11 months of age, both animals homozygous for the ART16 mutation were diagnosed with T cell lymphoma. One of these ART16/ART16 recipients was a male who received a transplant from a female sibling; the tumors in this recipient consist primarily of Y chromosome-positive cells. The other ART16/ART16 animal also presented with leukemia in addition to T cell lymphoma, while one of the ART12/ART16 compound heterozygote recipients presented with a nephroblastoma at a similar age. Human Artemis SCID patients have reported cases of lymphoma associated with a “leaky” Artemis phenotype. The naturally occurring Artemis SCID pig offers a large animal model more similar to human SCID patients and may offer a naturally occurring cancer model and provides a valuable platform for therapy development.

    We used TLI as immunosuppression for BMT in a patient with aplastic anemia. He recieved high dose cyclophosphamide and single dose TLI with 750 cGy, 12 cGy/min at his midplane, and bone marrow from HLA-matched twin brother. He is surviving without complications at 15 months. This procedure is well tolerated regimen. (author)

    There has been a rapid increase in the number of clinical trials using unselected bone marrow (BM) cells or the mononuclear fraction of BM cells for treating ischemic heart diseases. Thus far, no significant deleterious effects or complications have been reported in any studies using BM-derived cells for treatment of various cardiac diseases. Seven-week-old female Fisher-344 rats underwent surgery to induce acute myocardial infarction and were randomized into 3 groups of 16 rats, each receiving intramyocardial injection of either 7x10(5) DiI-labeled total BM cells (TBMCs), the same number of DiI-labeled, clonally expanded BM multipotent stem cells, or the same volume of phosphate-buffered saline in the peri-infarct area. Echocardiography 2 weeks after cell transplantation indicated intramyocardial calcification in 4 of 14 surviving rats (28.5%) in the TBMC group. Histological examination with hematoxylin and eosin staining and von Kossa staining confirmed the presence of extensive intramyocardial calcification. Alkaline phosphatase staining revealed strong positivity surrounding the calcified area suggestive of ongoing osteogenic activity. Fluorescent microscopic examination revealed that acellular calcific areas were surrounded by DiI-labeled TBMCs, suggesting the direct involvement of transplanted TBMCs in myocardial calcification. In contrast, in hearts receiving equal volumes of saline or BM multipotent stem cells delivered in the same manner, there was no evidence of calcification. These results demonstrate that direct transplantation of unselected BM cells into the acutely infarcted myocardium may induce significant intramyocardial calcification.

  6. Transient engraftment of syngeneic bone marrow after conditioning with high-dose cyclophosphamide and thoracoabdominal irradiation in a patient with aplastic anemia

    1990-01-01

    We describe the clinical course of a 16 year old girl with aplastic anemia who was treated by syngeneic bone marrow transplantation. Engraftment was not obtained by simple infusion of bone marrow without immunosuppression. The patient received a high-dose cyclophosphamide and thoracoabdominal irradiation, followed by second marrow transplantation from the same donor. Incomplete but significant hematologic recovery was observed; however, marrow failure recurred 5 months after transplantation. Since donor and recipient pairs were genotypically identical, graft failure could not be attributed to immunological reactivity of recipient cells to donor non-HLA antigens. This case report implies that graft failure in some cases of aplastic anemia might be mediated by inhibitory cells resistant to cyclophosphamide and irradiation

  7. Reduction and repopulation of recipient T4+ and T8+ T-lymphocytes in allogeneic bone marrow transplantation

    1986-01-01

    In eight recipients of allogeneic bone marrow grafts who had sex-mismatched donors, the reduction and subsequent repopulation of T4+ and T8+ T-lymphocytes of recipient origin were studied. The origin of the donor-recipient T4+ and T8+ T cells was studied using quinacrine staining of Y chromatin combined with T-cell typing for T4 and T8. Following chemoradiotherapy and bone marrow transplantation (BMT), T cells reached their nadir at a median of five (range 1-8) days after BMT. T8+ T cells decreased at a faster rate from the peripheral blood than T4+ T cells. The first T cells that appeared in the circulation at day 12 were predominantly T4+, and a large number of them were of recipient origin. Thereafter, they gradually decreased, and the numbers of T cells of donor origin increased. In the patients who had no or only minor complications, T4+ and T8+ T cells of donor origin repopulated the blood at similar rates. This pattern, however, was modified by severe graft-versus-host disease or by cytomegalovirus infection

    Incidence and prevalence of Mycobacterium fortuitum infection vary greatly by location and death is very rare except in disseminated disease in immunocompromised individuals. We present what we believe is the first case of bone marrow infection with Mycobacterium fortuitum in an HIV negative patient. Bone marrow examination revealed presence of numerous acid fast bacilli which were confirmed as Mycobacterium fortuitum on culture and by molecular analysis. Patient was managed successfully with amikacin and ciprofloxacin. (author)

    The examinations were carried out in order to ascertain whether bone marrow abnormalities can be detected in AIDS patients by means of magnetic resonance imaging or scintiscanning. In 16 of the 19 patients the NMR image and/or the scintiscan distinctly revealed bone marrow abnormalities, but there was no exact correlation to be found to immunological parameters, the peripheral blood picture, or the clinical stage of the HIV infection.

    2011-04-01

    Telomeres are noncoding DNA regions at the end of the chromosomes that are crucial for genome stability. Since telomere length decreases with cell division, they can be used as a signature of cell proliferation history. T-cell reconstitution in severe combined immunodeficiency (SCID) subjects, recipients of T-cell-depleted, allogeneic-related bone marrow cells, is due to the development and maturation of donor T-cell precursors in the infant's vestigial thymus and to homeostatic proliferation of mature T cells in the peripheral organs. Since T-cell function, thymic output, and T-cell clonal diversity are maintained long term in these patients, we investigated whether donor T-cell engraftment resulted in increased telomere shortening. Our study of seven SCID patients, following successful bone marrow transplantation, demonstrates that the patients' peripheral T cells did not exhibit greater than normal telomere shortening.

  11. Development of donor-derived thymic lymphomas after allogeneic bone marrow transplantation in AKR/J mice

    Yasumizu, R.; Hiai, H.; Sugiura, K.

    1988-01-01

    The transplantation of bone marrow cells from BALB/c (but not C57BL/6 and C3H/HeN) mice was observed to lead to the development of thymic lymphomas (leukemias) in AKR/J mice. Two leukemic cell lines, CAK1.3 and CAK4.4, were established from the primary culture of two thymic lymphoma, and surface phenotypes of these cell lines found to be H-2d and Thy-1.2+, indicating that these lymphoma cells are derived from BALB/c donor bone marrow cells. Further analyses of surface markers revealed that CAK1.3 is L3T4+ Lyt2+ IL2R-, whereas CAK4.4 is L3T4- Lyt2- IL2R+. Both CAK1.3 and CAK4.4 were transplantable into BALB/c but not AKR/J mice, further indicating that these cells are of BALB/c bone marrow donor origin. The cells were found to produce XC+-ecotropic viruses, but xenotropic and mink cell focus-forming viruses were undetectable. Inasmuch as thymic lymphomas are derived from bone marrow cells of leukemia-resistant BALB/c strain of mice under the allogeneic environment of leukemia-prone AKR/J mice, this animal model may serve as a useful tool not only for the analysis of leukemic relapse after bone marrow transplantation but also for elucidation of the mechanism of leukemogenesis

    1994-01-01

    Bone marrow and skin allografts from the same donor were transplanted to rats inflicted with 8 Gy γ-radiation combined with third degree burns of 15% body surface area within 6 hr post injury. Pathological changes of hematopoietic tissues and skin allografts were studied. All injured controls died within 7 days post injury without bone marrow regeneration; 50% of treated rats survived with living skin allografts on 50th day post injury. On days 100 and 480 post operation, grafted skin still survived well on recipients with normal ultrastructure. Epidermic cells of skin allografts proliferated on day 5, developed and repaired on day 10. Histological structure of the skin returned to normal on day 30 post operation. The regeneration of bone marrow appeared on 5th day, increased markedly on day 10, and almost completed on day 15 after bone marrow transplantation. However, the regeneration of lymphocytes in cortex of spleen and lymph nodes did not appear until day 15 of BMT. The results show that bone marrow and skin allograft transplantation at early time post injury in most severe combined radiation-burn injury have tremendous beneficial effects, and the skin allograft can survive for a long time

    A one-year old girl was admitted to the Okayama Red Cross Hospital on August 22, 1984 with fever and multiple furuncles. She was pale; peripheral blood examination revealed pancytopenia, and bone marrow aspiration showed a very hypoplastic marrow with only 4.5 percent of hematopoietic cells. Immediately anabolic steroid was administered but it failed to improve her hematological condition. She had a HLA identical brother and was transferred to the Department of Pediatrics of Nagoya University Hospital for bone marrow transplantation. After gut sterilization and an intravenous catheter were prepared, she received 500 mg of cyclophosphamide for successive 4 days followed by 750 rads of subtotal lymphoid irradiation, and 5 x 10 9 bone marrow cells were infused from her brother. Bone marrow aspiration on day 13 showed an increase in hematopoietic cells, and engraftment was confirmed by examinations of red blood cell type and sex chromosome. Hepatic transaminase increased from day 19, but was normalized by cessation of methotrexate and administration of betamethasone. Decreased immunoglobulin level after transplantation has recovered, and inverted OKT 4/8 ratio has also been normalized. After one year from transplantation, she is in a good hematological condition and is enjoying her life without any complication. (author)

    2007-01-01

    Full Text Available Patients with end stage heart failure have very few treatment options. The long waiting times for transplant and the complications associated with immunosuppression has led to the search for alternatives. Subsequent to the isolation and characterization of stem cells, tremendous advances have been made and the safety and feasibility of autologous bone marrow derived stem cells has been proven in preclinical studies. Clinical studies have also shown mobilized cells repair the infracted heart, improving function and survival. We have started a clinical study to evaluate the efficacy of bone marrow derived stem cells. Bone-marrow was aspirated from the right iliac crest and the stem cells were isolated by density gradient method and suspended according to the mode of delivery.From Jan 2007 till date 10 patients (8 adults, 2 children, age with end stage cardiovascular disorder of varied etiology (Ischemic left ventricular dysfunction - 6 patients, Primary pulmonary hypertension - 2 patients, Dilated cardiomyopathy -1 patient, Biventricular non-compaction -1 patient underwent stem cell therapy. All patients were evaluated and cardiac function was measured by using echocardiography and thallium scintigraphy. There were no procedure related complications. These patients are being regularly followed-up and one patient who has completed 6-month follow-up has shown improvement in perfusion as well as increase in ejection fraction of 10%. Stem cell therapy in patients with end-stage cardiovascular disorder might be a promising tool by means of angiogenesis and other paracrine mechanisms.

    We performed sixty patients with hematological malignancies the total body irradiation prior to bone marrow transplantation (TBI-BMT) from 1988 to 2000. We delivered our each patient hyperfractionated TBI consisting of 2 fractions of 3 Gy per day for 2 consecutive days following induction chemotherapy. It proved that TBI-BMT was a valuable treatment method for hematological malignancies which have poor prognosis. About the cumulative survival rate, patients of first remission were better outcome than patients beyond second remission. However, the therapy remained some problems which were the prophylaxis of GVHD for HLA-matched unrelated recipients. And we have to consider a new maintenance procedure to prevent relapse from transplanted donor cell. (author)

  18. Autologous transplantation of bone marrow mononuclear stem cells by mini-thoracotomy in dilated cardiomyopathy: technique and early results

    Renato Abdala Karam Kalil

    Full Text Available CONTEXT AND OBJECTIVES: There are few studies concerning bone marrow mononuclear cell (BMMC transplantation in cases of nonischemic dilated cardiomyopathy. This study describes a novel technique of BMMC transplantation and the results up to one year after the procedure. DESIGN AND SETTING: This was a case series to evaluate the safety and viability of the procedure, at Instituto de Cardiologia do Rio Grande do Sul. METHODS: Nine patients with symptomatic dilated cardiomyopathy, functional class III/IV and left ventricular ejection fraction (LVEF < 35% received BMMC (9.6 ± 2.6 x 107 cells at 20 sites in the ventricular wall, by means of thoracotomy of length 5 cm in the fifth left intercostal space. Echocardiograms and nuclear magnetic resonance (NMR were performed. RESULTS: There were no major complications. The functional class results for the first six patients (preoperatively and at two, four, eight and twelve-month follow-ups, respectively were: [IV-2, III-4] to [I-5, II-1] to [I-3, II-3] to [I-2, II-3] and [I-2, II-3]. Echocardiograms showed LVEF: 25.9 ± 8.2; 32.9 ± 10.4; 29.4 ± 7.2; 25.1 ± 7.9; 25.4 ± 6.8% (p = 0.023; and % left ventricular (LV fiber shortening: 12.6 ± 4.4; 16.4 ± 5.4; 14.3 ± 3.7; 12.1 ± 4.0; 12.2 ± 3.4% (p = 0.021. LV performance variation seen on NMR was non-significant. CONCLUSION: Intramyocardial transplantation of BMMC in dilated cardiomyopathy cases is feasible and safe. There were early improvements in symptoms and LV performance. Medium-term evaluation revealed regression of LV function, although maintaining improved functional class.

    1996-09-01

    For children with life-threatening inborn errors of metabolism without a matched related bone marrow donor, transplantation from an HLA genetically nonidentical donor is the only therapeutic option. To reduce the high risk of graft rejection in this setting without increasing the conditioning regimen, a protocol based on the infusion of an antiadhesion antibody directed against the CD11a (leukocyte function-associated antigen 1 [LFA-1]) molecule was performed by the European Bone Marrow Transplantation-European Society for Immunodeficiency group with promising results. To optimize engraftment, and thereby survival, further, the additional blockade of a second important leukocyte adhesion and signalization pathway mediated by the CD2 and LFA-3 interaction was attempted in a multicenter protocol conducted by the European Bone Marrow Transplantation-European Society for Immunodeficiency group. Results of this study (ie, engraftment and survival) were compared with a historical control group that received the anti-LFA-1 antibody alone. Factors that may have affected engraftment and survival were also considered in this study. Forty-four children with inborn errors, including inherited immunodeficiencies (excluding severe combined immunodeficiencies), Chédiak-Higashi syndrome, familial hemophagocytic lymphohistiocytosis, and malignant osteopetrosis, received bone marrow from HLA-nonidentical related donors or from HLA-identical unrelated donors at 13 European centers between August 1990 and June 1993. Bone marrow was depleted of T cells by use of either erythrocyte (E) rosetting or monoclonal antibodies (MoAbs) to prevent graft-versus-host disease. The conditioning regimen consisted of busulfan and cyclophosphamide for all patients plus etoposide for patients with osteopetrosis, familial hemophagocytic lymphohistiocytosis, and Chédiak-Higashi syndrome. Infusions of MoAbs specific for the CD11a and the CD2 molecules were started 4 and 3 days, respectively, before and

    Unrelated Bone marrow transplant was initiated thirty years ago. Though there are over millions of donors registered with the bone marrow registries worldwide, Asian patients rarely find a match with all these donors. Tzu Chi Marrow Donor Registry was established to meet this need. It has become the largest Asian marrow donor registry in the world. With the introduction of high technology to test the HLA of the donors and recipients, the success rate of bone marrow transplant is greatly improved among Asian countries. 50% of blood disease Asian patients who cannot find a bone marrow matched donor will be complemented by the establishment of cord blood banks in Taiwan.

    Full Text Available Aim: The objective was to describe an outbreak of bloodstream infections by Burkholderia cepacia complex (Bcc in bone marrow transplant and hematology outpatients. Methods: On February 15, 2008 a Bcc outbreak was suspected. 24 cases were identified. Demographic and clinical data were evaluated. Environment and healthcare workers' (HCW hands were cultured. Species were determined and typed. Reinforcement of hand hygiene, central venous catheter (CVC care, infusion therapy, and maintenance of laminar flow cabinet were undertaken. 16 different HCWs had cared for the CVCs. Multi-dose heparin and saline were prepared on counter common to both units. Findings: 14 patients had B. multivorans (one patient had also B. cenopacia, six non-multivorans Bcc and one did not belong to Bcc. Clone A B. multivorans occurred in 12 patients (from Hematology; in 10 their CVC had been used on February 11/12. Environmental and HCW cultures were negative. All patients were treated with meropenem, and ceftazidime lock-therapy. Eight patients (30% were hospitalized. No deaths occurred. After control measures (multidose vial for single patient; CVC lock with ceftazidime; cleaning of laminar flow cabinet; hand hygiene improvement; use of cabinet to store prepared medication, no new cases occurred. Conclusions: This polyclonal outbreak may be explained by a common source containing multiple species of Bcc, maybe the laminar flow cabinet common to both units. There may have been contamination by B. multivorans (clone A of multi-dose vials.

    Mucopolysaccharidosis VI is an inherited, metabolic defect in which a deficiency of arylsulfatase B, results in accumulation of glycosaminoglycans (GAG) in lysosomes. Arylsulfatase B activity was installed in an affected 2 year old siamese cat with no arylsulfatase B activity, excess urinary GAG, Alder-Reilly bodies in neutrophils, facial dysmorphia, corneal clouding, multiple epiphyseal dysplasia, and hind limb paresis. Following grafting of bone marrow from an immunologically nonreactive, female sibling with normal arylsulfatase B activity, increased arylsulfatase B activity and urinary excretion of hexuronic acid decreased by 19 days post transplantation. There were no metachromatic inclusions in circulating neutrophils, which were phenotypically female. The cat now has competent trilineage hematopoiesis, resolution of the facial dysmorphia, no corneal clouding, and improved movement of the head, neck, and mandible. The technique, sequence of hematologic recovery, and evidence of engraftment, are discussed. This may be a model for correction of mucopolysaccharidosis VI in man

    To describe the responses of mothers and fathers who were offered bone marrow transplantation (BMT) for their children with genetic disorders. Qualitative. Private hospital rooms/offices. Six mothers and 4 fathers of children with genetic disorders. The basic social-psychological problem confronting the parents was the conflicting alternatives of life versus death for their children. It was certain that these children would die from their genetic disorders but without having to endure the pain and suffering of a BMT. The BMT would be difficult, possibly resulting in death, but with a chance of survival. Parents believed that BMT was the only chance of survival for their children, leaving them no choice except to pursue the BMT treatment.

    Current transplant success allows recipients with previous contraindications to transplant to have access to this procedure with more frequency and safety. The concept of high-risk patient has changed since the first stages of transplantation. In the first studies, the high-risk concept was based on probability of early graft failure or on a patient's clinical condition to cope with high perioperatory morbimortality. Later on, this concept implied immunological factors that were crucial to ensure transplant success because hypersensitized or polytransfused patients experienced a higher risk of acute rejection and subsequent graft loss. Afterward, the presence of various comorbidities would redefine the high-risk concept for renal transplant mainly considering recipient's clinical aspects. Currently, the change in epidemiological characteristics of patients starting dialysis causes that we now deal with a greater increase of elderly patients, diabetic patients, and patients with history of cardiovascular disease. Today, high-risk patients are those with clinical features that predict an increase in the risk of perioperative morbimortality or death with functioning graft. In this review, we will attempted to analyze currents results of renal transplant outcomes in terms of patients and graft survival in elderly patients, diabetic patients, and patients with previous cardiovascular disease from the most recent experiences in the literature and from experiences in our center. In any of the groups previously analyzed, survival offered by renal transplant is significantly higher compared to dialysis. Besides, these patients are the recipient group that benefit the most with the transplant because their mortality while remaining on dialysis is extremely high. Hence, renal transplantation should be offered more frequently to older patients, diabetic patients, and patients with pretransplant cardiac and peripheral vascular disease. A positive attitude toward renal

    Fifteen bone marrow autotransplants (BMAT) in patients with acute myeloblastic leukemia (AML) were performed after the first remission. The mean age was 37 years (range 12 to 60 years). According to the morphological classification FAB, 8 patients had monocytic leukemia (M4, M5) and 7 myeloid leukemia (M1, M2, M3). The mean interval elapsed between the date of complete remission and the BMAT was 3.9 months (range 1 to 5-9 months). In 8 patients this interval was longer than 6 months and in 7 cases it was shorter than 6 months. After achievement of the complete remission all patients underwent certain cycles of intensification before the BMAT. Eight patients received only a cycle whereas 7 patients received more than one cycle (between 2 and 4). The conditioning protocol consisted of cyclophosphamide (CP) (60 mg/kg x 2) and total body radiotherapy (TBR) (10 Gy) in 9 patients; CP and busulfan in five; and CP, cytarabine at high doses and melphalan in one case. Marrow extraction was performed after completion of chemotherapy of intensification. In 5 cases the bone marrow was depleted of leukemic cells by previous in vitro treatment with ASTA-Z. There are at present 8 alive patients. The survival free of illness was 51.8%. Seven patients died: 3 cases because relapse of the leukemia, 3 due to attachment failure of the transplantation, and one patient suffered a viral myocarditis. The survival free of illness was significantly longer in those patients transplanted after 6 months of the complete remission.

    Frontotemporal dementia (FTD) is a neurodegenerative disease with devastating changes in behavioral performance and social function. Mutations in the progranulin gene (GRN) are one of the most common causes of inherited FTD due to reduced progranulin expression or activity, including in brain where it is expressed primarily by neurons and microglia. Thus, efforts aimed at enhancing progranulin levels might be a promising therapeutic strategy. Bone marrow (BM)-derived cells are able to engraft in the brain and adopt a microglial phenotype under myeloablative irradiation conditioning. This ability makes BM-derived cells a potential cellular vehicle for transferring therapeutic molecules to the central nervous system. Here, we utilized BM cells from Grn(+/+) (wild type or wt) mice labeled with green fluorescence protein for delivery of progranulin to progranulin-deficient (Grn(-/-)) mice. Our results showed that wt bone marrow transplantation (BMT) partially reconstituted progranulin in the periphery and in cerebral cortex of Grn(-/-) mice. We demonstrated a pro-inflammatory effect in vivo and in ex vivo preparations of cerebral cortex of Grn(-/-) mice that was partially to fully reversed 5 months after BMT. Our findings suggest that BMT can be administered as a stem cell-based approach to prevent or to treat neurodegenerative diseases.

    The effect of a localized viral infection on the occurrence of graft-vs.-host disease (GVHD) was examined in allogeneic rat bone marrow chimeras (ACI/LEW). Animals without clinical evidence of GVHD, 62 days after bone marrow transplant, were infected in salivary and lacrimal glands with sialodacryoadenitis virus (SDAV), and sacrificed 8-25 days postinfection. Using established histologic criteria, GVHD was found more frequently in salivary and lacrimal glands of SDAV-infected chimeras than uninfected chimeras. Skin and oral mucosa, tissues not infected by the virus, showed no differences in occurrence of GVHD, suggesting that the viral infection induced only local and not systemic GVHD. GVHD and SDAV infection, which are histologically similar, were differentiated by examining tissues for SDAV antigen using immunoperoxidase technique. Histologic changes were present for at least 1 week longer than viral antigen, suggesting they represented GVHD rather than viral infection. GVHD and SDAV infection were also differentiated by looking for a histologic feature characteristic of GVHD and not found in SDAV infection (periductal lymphocytic infiltrate). This was found in SDAV-infected chimeras more frequently than uninfected chimeras, suggesting that the viral infection somehow induced GVHD. Results showed a localized increase in the occurrence of GVHD subsequent to localized viral infection

    Purpose: Our previous study reveals bone marrow transplantation (BMT) recruits host marrow-derived myelomonocytic cells to radiation-injured intestine, enhancing stromal proliferation, leading secondarily to epithelial regeneration. In this study, we propose BMT ameliorates intestinal damage via paracrine mechanisms. Materials and methods: Angiogenic cytokines within the intestinal mucosa of mice after whole body irradiation (WBI) with or without BMT were measured by cytokine array and ELISA. BM conditioned medium (BMCM) with or without treatment with neutralizing antibodies to angiogenic cytokines were continuously infused into mice for three days after radiation. Carrageenan was used to deplete myelomonocytic cells of mice. Results: BMT increased VEGF, bFGF and other angiogenic and chemotactic cytokines in the intestinal mucosa within 24 h after WBI. Infusion of BMCM ameliorated radiation-induced intestinal damage with improved stromal activity and prolonged survival of mice. Neutralization of bFGF, PDGF and other angiogenic cytokines within BMCM abolished the mitigating effect to the intestine. Pretreatment of carrageenan to recipient mice reversed some of the cytokine levels, including VEGF, bFGF and IGF within the intestinal mucosa after BMT. Conclusions: Our result suggests BMT recruits host myelomonocytic cells and enhances intestinal stroma proliferation after radiation by secreting cytokines enhancing angiogenesis and chemotaxis. Host myelomonocytic cells further uplift the paracrine effect to enhance intestinal mucosal recovery.

    The time of entry of prothymocytes into the thymus after lethal irradiation and bone marrow transplantation (BMT) was determined by exposing the thymus only or the whole body with the thymus shielded to a second irradiation after different intervals. The repopulation of the thymus by donor type cells was determined by a thymus repopulation assay using donor specific markers. Reirradiation of the thymus kills the prothymocytes that have entered the thymus during the interval. It was found that reirradiation of the thymus from 48 hours after BMT onwards increasingly delayed thymus regeneration. This shows that donor prothymocytes do not enter the thymus until about 2 days after BMT and that they continue to do so during at least 3 subsequent days. In the second reirradiation protocol thymus regeneration occurred earlier in the shielded thymus than in thymuses of whole body irradiated mice. Earlier thymus regeneration was not seen in mice that were reirradiated at 24 hours after BMT, but occurred only when irradiation took place at 48 hours and later. These data are consistent with those obtained in the first protocol. The results are in contradiction with results of direct homing experiments, which showed entrance of donor cells within 3 hours after BMT. A functional assay demonstrated that the early appearing cells cannot be prothymocytes. In retransplantation experiments it was shown that the bone marrow may indeed be the initial homing site of prothymocytes. 14 refs.; 5 figs.; 1 table

    Exposure of bone to ionizing radiation, as occurs during radiotherapy for some localized malignancies and blood or bone marrow cancers, as well as during space travel, incites dose-dependent bone morbidity and increased fracture risk. Rapid trabecular and endosteal bone loss reflects acutely increased osteoclastic resorption as well as decreased bone formation due to d
