A 16 year old boy underwent allogeneic bone marrow transplantation (BMT) from an human leukocyte antigen (HLA)-identical sibling for severe aplastic anaemia. He was symptomatic for 7 years before transplantation and had received multiple red blood cell and platelet transfusions. Conditioning for BMT consisted of cyclophosphamide, antilymphocyte globulin and total lymphoid irradiation. Engraftment was rapid, there was no evidence of rejection despite the history of multiple blood product transfusions and he did not develop acute or chronic graft versus host disease. He was well for the first 8 months after transplantation but then developed fevers, interstitial pneumonia, herpes simplex infections and cytomegalovirus enteritis. Serological studies revealed antibodies to human immunodeficiency virus (HIV) and he was considered to have acquired immune deficiency syndrome (AIDS). Retrospective analysis of the serum samples showed that he was seronegative for HIV until approximately 10 months before transplantation when his serum became HIV positive. Lymphocyte function studies done after transplantation suggested immunologic recovery at 3 months post-transplant with a brisk though subnormal response to phytohaemagglutinin stimulation. T cell subset analysis performed subsequently showed complete absence of CD4 positive cells indicating immune incompetence which was associated with clinical features of AIDS. Bone marrow transplantation had failed to produce sustained immunologic reconstitution and prevent the progression of HIV to which he ultimately succumbed.

Twenty-eight patients aged 16-50 years with chronic myeloid leukaemia (CML) underwent allogeneic bone marrow transplantation (BMT) using human leukocyte antigen (HLA)-identical sibling donors. Of the 28 patients, 21 were in chronic phase, five were in accelerated phase and two were in blast phase at the time of BMT. Twenty-three of the patients survived more than 63-2187 days after BMT, 21 in continuous complete remission and two with haematologic relapse of CML. Two patients died of interstitial pneumonitis and one died of relapsed CML, cerebral aspergillosis and cytomegalovirus enterocolitis. The overall probability of survival at six years was 78% +/- 9% (mean +/- standard error) and of disease free survival 66 +/- 11%. For patients transplanted in chronic phase, the survival probability was 90 +/- 6%, while all of the patients undergoing BMT in chronic phase within the first year after diagnosis were alive with a relapse-free survival of 88 +/- 12%. The actuarial probability of occurrence of acute graft-versus-host disease (GVHD) was 57 +/- 9%, while for Grades II and III GVHD it was 28 +/- 9%. Chronic GVHD occurred in 18 of 25 patients at risk. The majority of patients had a Karnofsky performance score at latest follow-up of at least 90% (range 50-100). We conclude that allogeneic BMT is effective, curative therapy for CML and that BMT performed earlier in the natural history of the disease is associated with the best outcome.

Since 1979, a total of 17 patients with Wiskott-Aldrich syndrome have undergone allogeneic bone marrow transplantation at Memorial Sloan-Kettering Cancer Center. Eleven patients received marrow from either human leukocyte antigen (HLA) genotypically identical siblings (nine patients) or an HLA phenotypically identical parent (two patients). Six patients received marrow grafts from HLA-disparate parents. Cytoreduction was accomplished with busulfan and cyclophosphamide for the HLA-identical recipients and total-body irradiation followed by high-dose cytarabine therapy in the mismatched recipients. All 11 recipients of HLA-identical marrow had successful grafts, and 10 of 11 are alive and well 28 to 145 months after transplantation. One patient died 10 months after transplantation of chronic graft-versus-host disease and interstitial pneumonitis caused by cytomegalovirus. Only one of the six mismatched graft recipients survives, 52+ months after transplantation; the other patients have died of extensive chronic graft-versus-host disease (one patient), lymphoma (three patients), or progressive pancytopenia accompanying Candida sepsis (one patient). Thus bone marrow transplantation represents the treatment of choice in patients with Wiskott-Aldrich syndrome who have an HLA-identical donor. However, our approach for patients lacking a histocompatible family donor requires modifications to overcome allogeneic resistance and decrease the posttransplantation immunoincompetence in these patients.

The use of intensive therapy together with transplantation of marrow from a suitable donor is the only established curative treatment for patients with chronic myeloid leukemia (CML). However, marrow transplantation is hazardous, costly and applicable to relatively few patients. Therefore, we evaluated the results and limitations of marrow transplantation for CML and discussed new treatment strategies. We decided to select a limited number of papers that focused on the relevant issues rather than to undertake an exhaustive comparison of treatment results from different centres. Patients with CML in the chronic phase who receive marrow from a sibling with the same human leukocyte antigen type can expect to have a long-term disease-free survival rate of 50%. However, the procedure is associated with a mortality rate of 30%, mainly because of graft-versus-host disease (GVHD) and interstitial pneumonitis. Moreover, because of the requirements for age and histocompatibility only 10% of patients with chronic-phase CML are currently eligible. Transplantation earlier in the chronic phase (within 1 year after diagnosis), the use of marrow from matched, unrelated donors and the development of improved methods for reducing the incidence of GVHD all hold promise. In addition, the preliminary results of intensive therapy followed by transplantation with cultured autologous marrow have been encouraging. If further progress is to be made, continued optimism coupled with carefully developed and executed studies will be necessary.

Eighty consecutive patients were transplanted with human leukocyte antigen (HLA)-identical sibling marrow for acute myelogenous leukemia (AML, N = 29), acute lymphoid leukemia (ALL, N = 23), or chronic myelogenous leukemia (CML, N = 28). Donor marrow was depleted of lymphocytes using counterflow centrifugation. Median age of the recipients was 31 years. Pretransplant conditioning consisted of cyclophosphamide and fractionated total body irradiation (TBI) with a low (4.1 +/- 0.3 cGy/min) or high (13.1 +/- 1.6 cGy/min) midline average dose rate. In 43 patients, cytosine-arabinoside or anthracyclines were added to the conditioning regimen. Immunoprophylaxis posttransplant consisted of methotrexate (MTX) alone, cyclosporine A (CsA) in combination with MTX, or CsA alone; two patients received no immunoprophylaxis at all. Graft failure occurred in 4 of 77 evaluable patients (5%). The probability of acute graft-versus-host disease (GVHD) greater than or equal to grade 2 at day 100 after transplantation was 15%. The projected 3-year estimate of extensive chronic GVHD was 12%. Only three patients died of cytomegalovirus-interstitial pneumonitis. The projected 3-year probability of relapse was 30% (95% confidence interval [CI], range 8% to 53%) in transplants for AML in first complete remission (CR1), 35% (95% CI, 1% to 69%) after transplantation for ALL in CR1, and 38% (95% CI, 2% to 74%) after transplantation for CML in first chronic phase (CP1). The projected 3-year probability of leukemia-free survival (LFS) was 56% (95% CI, 35% to 77%) after transplantation for AML-CR1, 42% (95% CI, 16% to 69%) in patients transplanted for ALL-CR1, and 49% (95% CI, 18% to 80%) after transplantation for CML-CP1. After transplantation for AML-CR1, ALL-CR1, or CML-CP1, the median follow-up time for leukemia-free survivors was 31+, 30+, and 21+ months, respectively. Probabilities of relapse, survival, and LFS in AML-CR1 and ALL-CR1 transplants were comparable with those reported in recipients of untreated grafts. In patients transplanted for CML-CP1, probability of relapse was higher and probability of LFS was lower than in recipients of untreated grafts. In transplants for leukemia in CR1 and CP1, preparative regimen and immunoprophylaxis posttransplant were not associated significantly with the probability of acute GVHD greater than or equal to grade 2, extensive chronic GVHD, relapse, survival, or LFS. In bone marrow transplantation for leukemia, counterflow centrifugation is a useful technique for the prevention of GVHD.(ABSTRACT TRUNCATED AT 400 WORDS)

This article compares the outcome of 14 patients with primary refractory acute leukemia who underwent bone marrow transplantation from human leukocyte antigen (HLA)-identical donors with that of 18 age-matched control patients who received chemotherapy. Complete clearing of leukemia was seen in all 14 transplanted patients. Five of the transplanted patients are alive 98 to 1790 days posttransplant, and four are free of leukemia. Nine patients have died, eight with severe graft-versus-host disease associated with interstitial pneumonia or systemic infections and one with relapse from chemotherapy-associated infections. Engraftment was seen in all patients. Severe graft-versus-host disease (grades III and IV) was seen in ten patients and resolved in three patients following high-dose corticosteroid treatment. Three of the 18 control patients are alive, none of them in complete remission. It appears that the combination of piperazinedione and total-body irradiation followed by allogeneic transplant is effective induction treatment for primary refractory acute leukemia and will be considered in the future as first salvage treatment for patients failing induction treatment.

The association of granulocyte transfusions with cytomegalovirus infection and interstitial pneumonitis in allogeneic marrow transplant recipients was reviewed. Data from 387 patients with aplastic anemia or acute leukemia receiving transplants from human leukocyte antigen-matched siblings were analyzed. Acquisition of cytomegalovirus infection was higher in recipients of prophylactic and therapeutic granulocytes than in control subjects. The incidence was significantly different, however, only in cytomegalovirus seronegative patients who received granulocytes from seropositive granulocyte donors. There was no significant increase in the total incidence of or mortality from all forms of interstitial pneumonitis.

The outcomes of 69 patients who received allogeneic bone marrow grafts for autosomal recessive osteopetrosis in the period between 1976 and 1994 were analyzed retrospectively. Four patients received bone marrow transplants (BMT) without prior myeloablative conditioning; transient osteoclast function was demonstrated in one of them. Sixty-five patients received myeloablative pretreatment. Recipients of a genotypically human leukocyte antigen (HLA)-identical BMT had an actuarial probability for 5-year survival, with osteoclast function, of 79%; recipients of a phenotypically HLA-identical bone marrow graft from a related or unrelated donor, or one HLA-mismatched graft from a related donor, had an actuarial probability for 5-year survival, with osteoclast function, of 38%; patients who received a graft from an HLA-haplotype mismatched related donor had a probability for 5-year survival of only 13%. The main problems in haplotype-nonidentical BMT were graft failure and BMT-related complications such as sepsis, bleeding, and interstitial pneumonia. Osteoclast function developed in all patients with full engraftment. Recovery of osteoclast function was associated with severe hypercalcemia in 24% of the patients with engraftment, especially those older than 2 years of age. At the time of BMT, severe visual impairment was present in 35% of the patients; of the 15 patients who had visual impairment at the time that a successful BMT was performed, two had improvement after BMT (13%). Within the total group, one patient had neurodegeneration. Engraftment of healthy donor cells had no influence on the progression of that abnormality and BMT thus had no beneficial effect on this phenotype of osteopetrosis. In general, however, early BMT remains the only curative treatment for autosomal recessive osteopetrosis.

We report here a case of 33 year-old-man with refractory bilateral pneumothoraces during the treatment for interstitial pneumonitis 6 months after bone marrow transplantation (BMT). He was diagnosed as having acute myelogenous leukemia (AML) M1. He was treated with chemotherapy, and cerebral irradiation. BMT was performed in August 1989 from a sibling donor whose human leukocyte antigen was matched, ABO blood type mismatched. Preconditioning regimen was cyclophosphamide and total body irradiation (TBI). BMT was successful without major graft versus host disease. Thereafter he complained of respiratory symptom and was admitted on June 14 1990. Computed tomogram (CT) scan showed interstitial and alveolar shadows. We started the treatment against bacterial infection, Pneumocystis carinii, cytomegalovirus (CMV) and against interstitial pneumonitis with bolus dose of steroid. The transbronchial lung biopsy specimen revealed interstitial pneumonitis without typical CMV nor pneumocystis carinii pneumonia. Although a CT scan showed improvement of pneumonitis, bilateral pneumothoraces occurred. The adhesion therapy became successful after the reduction of steroid dosage. A pneumothorax rarely occurs after BMT. In this case it is speculated that TBI might be responsible for interstitial pneumonitis, and the steroid might have inhibited the adhesion therapy of pneumothorax.

The case of a 3-month-old boy with lymphoid interstitial pneumonia (LIP) is reported. He had cough and tachypnea, his weight gain was poor and a chest radiograph showed microgranular shadows in almost all lung areas. Histological investigations revealed severe cellular infiltration by a variety of lymphoid and plasma cells with lymphoid follicle formation in the alveolar walls and also around the bronchioles. Foamy macrophages, a few lymphocytes and exudate filled the alveolar spaces. Epithelial cells lining the air spaces expressed human leukocyte antigen (HLA)-DR. Lymphocytes and macrophages in the alveolar spaces expressed transforming growth factor (TGF)-beta strongly. Serum TGF-beta 1 concentrations were measured eight times during the course of his illness. They exceeded the upper end of the normal range in four samples and were within it in the others. These results suggested that dysfunction of the immune system, especially abnormal expression of HLA-DR in non-immune cells and exaggerated production of TGF-beta played important roles in the pathogenesis of LIP in this patient.
