[Influence of clinical status on the efficacy of stored platelet transfusion].

The efficiency of stored platelet transfusion was evaluated in terms of clinical status in 136 thrombocytopenic patients. In a paired prospective study in which fresh platelets were used as controls, clinical efficiency was assessed on the basis of the ability to increase platelet count (recovery) and the interval to the next transfusion (D). In 48 clinically stable patients, recovery of fresh and stored platelets was similar (47% and 41% respectively) and the interval to the next transfusion was D4 and D3.

Use of an anti-interleukin-2 receptor monoclonal antibody for GVHD prophylaxis in unrelated donor BMT.

Severe acute GVHD remains the main complication in unrelated donor BMT (UD-BMT). The previous encouraging reports on the use of anti-IL-2 receptor monoclonal Ab (33B31) for GVHD prophylaxis in genoidentical BMT led us to add this Ab to the standard GVHD prophylaxis regimen (MTX plus CsA). Sixty-four consecutive patients received 33B31, 20 mg on days 1 and 2, then 10 mg per day from day 3 to day 28 in association with CsA and MTX.

[Hematopoietic growth factor (GM-CSF) after autologous bone marrow transplantation. A randomized, double-blind, multicenter study in 91 cases of non-Hodgkin's malignant lymphomas].

To a great extent, the risks of autologous bone marrow transplantation are related to neutropenia. Although the efficacy of the recombinant human granulocyte-macrophage colony-stimulating factor (rhu GM-CSF) on neutrophil recovery has appeared in numerous open trials, only a few randomized studies have hitherto been published. Ninety-one patients with non-Hodgkin's malignant lymphoma treated with ablative chemotherapy followed by purged or unpurged bone marrow transplantation were entered in a placebo-controlled, double-blind randomized study; 44 patients received GM-CSF (E.

Bone marrow transplantation (BMT) in 14 children with severe sickle cell disease (SCD): the French experience. GEGMO.

Fourteen S/S children with severe SCD were transplanted with marrow from HLA identical siblings. All developed frequent (> 4/y) vasoocclusive crises (VOC) and recurrent acute chest syndrome episodes (n:10), osteitis (n:3), osteonecrosis (n:3), strokes (n:3) or frequent massive deglobulisation (n:2). Two children undergone splenectomy, 2 were chelated and 2 had erythroid allo-immunization.

Improvement in outcome for children receiving allogeneic bone marrow transplantation in first remission of acute myeloid leukemia: a report from the Groupe d'Etude des Greffes de Moelle Osseuse.

Purpose: We retrospectively analyzed the outcome of children with acute myeloid leukemia (AML) in first complete remission (CR) who received HLA-identical bone marrow transplantation (BMT) in 13 French transplant centers.

Patients And Methods: Seventy-four children were treated from June 1979 through December 1990. The conditioning regimen included total-body irradiation (TBI) in 54 cases and busulfan in 20.

Recombinant human granulocyte-macrophage colony-stimulating factor after high-dose chemotherapy and autologous bone marrow transplantation with unpurged and purged marrow in non-Hodgkin's lymphoma: a double-blind placebo-controlled trial.

The toxicity of autologous bone marrow transplantation (ABMT) is correlated to neutropenia. Although recombinant human granulocyte-macrophage colony-stimulating factor (rhu GM-CSF) seems to hold promise in accelerating neutrophil recovery, few analyses from randomized studies are presently available. Ninety-one patients with non-Hodgkin's lymphoma receiving high-dose ablative chemotherapy followed by ABMT with unpurged or purged marrow were included in a randomized, double-blind, placebo-controlled trial.

Sclerodermatous chronic graft-versus-host disease. Analysis of seven cases.

Background: Sclerodermatous chronic graft-versus-host disease is a disabling complication after allogeneic bone marrow transplantation from HLA-identical sibling donors. Only a few series of patients have been reported and the dermatologic features have never been extensively described.

Objective: The purpose of the study was to describe clinical and biologic features of chronic sclerodermatous graft-versus-host disease and to compare them with scleroderma.

A simple, efficient washing procedure for cryopreserved human hematopoietic stem cells prior to reinfusion.

We describe our experience with a washing procedure used on cryopreserved, thawed bone marrow (BM) and peripheral blood stem cell (PBSC) grafts prior to autologous transplantation in 50 and 12 patients respectively. The procedure consists of a stepwise dilution with 2% human serum albumin and centrifugation performed either manually or using a blood cell processor (Cobe 2991). In vitro studies showed mean recoveries of 80.

Cogan's syndrome. An unusual etiology of urticarial vasculitis.

We report the case of an 18-year-old black woman with urticarial vasculitis, vestibuloauditory dysfunction and superficial keratitis. Oral steroid therapy was effective in reducing most clinical manifestations with high-dosage dependency. However, only intravenous pulses of methylprednisolone allowed slight improvement of hearing.

Toxic epidermal necrolysis after bone marrow transplantation: study of nine cases.

Acute graft-versus-host reaction after allogeneic bone marrow transplantation has been reported to induce toxic epidermal necrolysis. To assess the respective role of acute graft-versus-host disease and of drug reaction in this setting, we retrospectively reviewed nine cases of toxic epidermal necrolysis that occurred in a series of 152 allogenic bone marrow recipients. In five cases visceral involvement was suggestive of acute graft-versus-host disease without any drug more than "doubtfully" suspected.

Allogeneic bone marrow transplantation in adults with Burkitt's lymphoma or acute lymphoblastic leukemia in first complete remission.

The prognosis of adults with Burkitt's lymphoma is very poor and depends on initial CNS and/or bone marrow involvement. We report results in nine adult patients with CNS (n = 9) and/or bone marrow involvement (n = 7) treated in first complete remission (CR) with allogeneic bone marrow transplantation (BMT). CNS treatment before the conditioning regimen consisted of cranial irradiation at 15 Gy (n = 8) and intrathecal chemotherapy (n = 9).

Frequent detection of minimal residual disease by use of the polymerase chain reaction in long-term survivors after bone marrow transplantation for chronic myeloid leukemia.

The polymerase chain reaction (PCR) allows the detection of minimal amounts of nucleic sequences and has been successfully used to test for the chronic myeloid leukemia-specific bcr/abl transcripts. We studied blood samples from 17 patients who had undergone allogeneic bone marrow transplantation for CML, using a modified polymerase chain reaction-based assay for the detection of leukemic mRNA. This nested PCR technique was found to be highly sensitive, detecting the chimeric bcr/abl transcript in 16 of 17 patients including several long-term survivors.

Interstitial pneumonitis and venocclusive disease of the liver after bone marrow transplantation.

One hundred and seventy patients were analysed for interstitial pneumonitis and 151 for venocclusive disease of the liver after bone marrow transplantation. We present our results with emphasis on the role of the parameters of single fraction total body irradiation.

Central nervous system relapses after bone marrow transplantation for acute lymphoblastic leukemia in remission.

This study defines the risk of central nervous system (CNS) relapse in patients undergoing bone marrow transplantation (BMT) for acute lymphoblastic leukemia (ALL) in remission, with no posttransplant prophylactic CNS therapy. Ninety-two consecutive patients in complete remission received BMT for ALL (n = 82) or high-grade non-Hodgkin's lymphoma with poor prognostic factors at diagnosis (n = 10). Sixty-six patients received allogeneic BMT (Allo-BMT) and 26 patients, without an identical sibling, underwent autologous BMT (Auto-BMT).

Mediastinal diffuse large-cell lymphoma with sclerosis: a condition with a poor prognosis.

Twenty patients (17 women, three men) with mediastinal diffuse large-cell lymphoma with sclerosis are reported. At the time of diagnosis, the disease was confined to supradiaphragmatic areas in all patients but two, who had kidney involvement (seven were stage I, 11 were stage II, and two were stage IV). A B-cell phenotype was demonstrated in nine of the 11 cases that were analyzed for cell lineage.

Bone marrow transplantation for adult poor prognosis lymphoblastic lymphoma in first complete remission.

Twenty-five adult patients, 19 males, six females, age 16-43 years (median 23), with lymphoblastic lymphoma received allogeneic or autologous bone marrow transplantation in first complete remission. Twelve patients were Murphy stage IV with bone marrow and/or CNS involvement and 13 were stage III of whom nine had thoracic involvement. Complete remission was achieved with an intensive anthracycline containing multiagent chemotherapy protocol.

Acral erythema and systemic toxicity related to CHA induction therapy in acute myeloid leukemia.

Seventy-two adult patients with previously untreated acute myeloid leukemia received the CHA regimen as induction chemotherapy: CCNU 80 mg/m2 on day 1, Adriamycin 35 mg/m2 i.v. on days 1, 2 and 3, and continuous infusion of cytarabine 100 mg/m2/24 h from day 1 to 10.

[Mixed lympho-epidermal cell cultures: value in bone marrow grafts].

Graft-versus-host disease (GVHD) is the major complication of allogeneic HLA-identical bone marrow transplantation. GVHD is induced by the activation of mature T cells in the graft which react against minor antigens of the recipient. Mixed epidermal cell-lymphocyte cultures (MELC), which constitute an in vitro model of epidermal cell-lymphocyte interactions, make it possible to study the presentation of antigens to the lymphoid cells by epidermal Langerhans cells.

Failure of a CD18/anti-LFA1 monoclonal antibody infusion to prevent graft rejection in leukemic patients receiving T-depleted allogeneic bone marrow transplantation.

CD18 antibodies react with the common beta chain of the human leukocyte function antigen (LFA1)* and thus block the functions mediated by the three identified molecules in humans. A murine CD18 monoclonal antibody was infused in 8 leukemic patients receiving allogeneic T-depleted bone marrow transplantation in order to prevent graft rejection. This was part of the conditioning, including total-body irradiation and high-dose chemotherapy, given to all patients.

The mixed epidermal cell lymphocyte-reaction is the most predictive factor of acute graft-versus-host disease in bone marrow graft recipients.

Risk factors for acute graft-versus-host disease (GvHD) remain controversial. We performed uni- and multivariate statistical analyses on a series of 37 patients receiving a non-depleted allogeneic bone marrow transplant from an HLA-identical sibling donor for a haematological malignancy, in order to identify risk factors for GvHD. Three factors were associated with development of moderate to severe GvHD: a positive mixed epidermal cell-lymphocyte reaction (MECLR) between donor and recipient, previous pregnancies in female donors and chronic myeloid leukaemia diagnosis.

Venocclusive disease of the liver after allogeneic bone marrow transplantation in man.

One hundred and fifty-one consecutive patients underwent allogeneic bone marrow transplantation (B.M.T.

Allogeneic bone marrow transplantation in adults with acute lymphoblastic leukemia in first complete remission.

Twenty-seven patients ranging in age from 15 to 36 years participated in a pilot study, and underwent allogeneic bone marrow transplantation (BMT) for acute lymphoblastic leukemia (ALL) in first complete remission (CR) in four French centers. All patients were grafted from human leukocyte antigen/mixed leukocyte culture (HLA/MLC) identical sibling after conditioning regimen consisting of cyclophosphamide and total body irradiation (TBI). Sixteen patients are alive in persistent first remission, with a median follow-up of 56 months (range, 41 to 82 months).
