We studied clinical effect of a combination therapy with cefozopran (CZOP) and tobramycin (TOB) for infections in 80 patients with hematologic diseases in 15 institutes. Combined doses with CZOP 2 g and TOB 60-90 mg twice a day had been given intravenously. Of the 80 patients, 61 patients (42 with acute leukemia, 10 with malignant lymphoma, 3 with aplastic anemia, 2 with chronic myeloid leukemia, 2 with multiple myeloma, and 2 with myelodysplastic syndrome) were evaluable. Those consisted of 6 patients with septicemia, 49 with suspected septicemia, 3 with pneumonia, and 3 with other infections. Clinical efficacy by the treatment was excellent in 24, good in 17, fair in 9, and poor in 11 patients, and the overall efficacy rate including excellent and good was 67.2%. Microbiologically, 5 of the 6 patients with septicemia (1 coagulase negative Staphylococcus, 2 S. pneumoniae, 1 S. oralis, and 1 E. coli) were responded. The efficacy rate in patients with severe granulocytopenia showing 100/microliter or lesser neutrophil counts during the drug administration was 57.1% (12/21). Side effects and abnormal changes of clinical laboratory findings were observed in 5 patients, and 16 patients, respectively, but most of them were mild. The findings above suggested that the combination therapy with CZOP and TOB is useful as an empiric therapy for severe infections in patients with hematologic diseases.

Human herpesvirus-6 (HHV-6), like all the other herpes viruses, remains latent in host cells after primary infection but can be reactivated in immunocompromised patients causing fever, skin rash, bone marrow (BM) suppression, pneumonitis, sinusitis and meningoencephalitis. We describe the case of a man with chronic myelogenous leukemia who developed encephalitis associated with acute graft-versus-host disease two months after a T-cell-depleted mismatched peripheral blood stem cell transplant. Magnetic resonance images of the brain revealed multiple bilateral foci of signal abnormality. HHV-6 was the only pathogen detected in cerebrospinal fluid by PCR. Treatment with both ganciclovir and foscarnet was unsuccessful and the patient gradually deteriorated and died. Other cases of HHV-6 encephalitis after bone marrow transplantation are reviewed.

Hydroxyurea is a cytotoxic agent indicated in the treatment of a variety of malignant and nonmalignant conditions. Apart from dose-related bone marrow suppression, this antineoplastic agent is generally well tolerated. This report describes a patient with chronic myeloid leukemia who developed severe pneumonitis within four weeks of beginning therapy with hydroxyurea. Pathological examination of a lung specimen obtained by video-assisted thoracoscopic lung biopsy revealed extensive active alveolar and interstitial inflammation, and poorly formed granulomas. After the cessation of hydroxyurea and treatment with systemic corticosteroids, both clinical and radiological resolution of pneumonitis occurred. Physicians using hydroxyurea must be aware of its potentially life-threatening pulmonary toxicity.

We report on a patient with chronic myelogenous leukemia who developed bronchiolitis obliterans organizing pneumonia (BOOP) after allogeneic bone marrow transplantation (BMT). A 19-year-old Japanese male complained of dry cough and dyspnea 7 months after BMT. The chest X-ray and computed tomography revealed patchy infiltrates bilaterally. Lung function test, lung biopsy and bronchoalveolar lavage were consistent with the diagnosis of BOOP. The patient also suffered from suspected graft-versus-host disease (GVHD) of the liver, after discontinuation of cyclosporine. Furthermore, prednisolone proved effective against the BOOP and the liver dysfunction. These findings indicate that BOOP is a possible pulmonary manifestation of chronic GVHD, and that immunological mechanisms may have effected the onset of BOOP after BMT in this case.

We present a case of adenovirus (ADV) infection in a patient who had undergone nonmyeloablative stem cell transplantation (NST). A 50-year-old man with chronic myelogenous leukemia in the second chronic phase underwent NST from an HLA 2-loci-mismatched sibling. ADV hemorrhagic cystitis developed and progressed to lethal pneumonia. ADV was isolated from urine, bronchoalveolar lavage fluid, and postmortem specimens of kidney and liver. Because there are few reports of lethal pneumonia associated with ADV in Japan, we present the case and discuss the cause of and therapy for the infection.

We report an unusually severe case of pneumatosis cystoides intestinalis in an adult female patient undergoing chemotherapy for lymphoblastic crisis in chronic myelogenous leukemia. An impressive accumulation of gas was not only detected within the intestinal wall and mesentery but also in the peritoneum, retroperitoneum, mediastinum and cervical subcutaneous tissue. The patient was almost asymptomatic and fully recovered within a few days of treatment. In addition to chemotherapy, the patient was receiving trimethoprim/sulfamethoxazole for pneumocystis carinii pneumonia and lactulose for constipation. Mucosal damage due to chemotherapy and depletion of tetrahydrofolic acid, changes in bowel flora induced by antibiotic treatment, and the intake of unabsorbable carbohydrates may be responsible for the severity of the disease.

Pulmonary complications are frequently encountered in patients with hematological malignancy. The optimal therapeutic decision including open lung biopsy (OLB) for such patients is uncertain. We herein examine the clinical impact of OLB on these patients. Seven patients with progressively diffuse pulmonary infiltrates despite aggressive medical treatment were examined. The underlying diseases, prior treatment for presumptive pneumonia, the change in therapeutic approach after operation, and clinical outcome were reviewed retrospectively. Diffuse pulmonary infiltrates were caused by infection in two patients and by noninfectious etiology such as alveolar proteinosis, idiopathic interstitial pneumonitis, leukemic involvement, and drug-induced alveolar damage in the others. Four patients who had serious underlying hematologic diseases such as myelodysplastic syndrome, acute and chronic myeloid leukemia, and T cell lymphoma died. Three patients with acute lymphoid leukemia survived. In two of these three, change of therapeutic strategies after OLB was created for the survival. OLB in patients with hematological malignancy may be useful in selected patients with a treatable hematologic disease who have treatable underlying causes of the pulmonary infiltrate.

The aim of this study was to evaluate the efficiency and risks of T-cell depletion in prevention of graft versus host disease (GVHD) using HLA haploidentical family donors as an alternative source of hematopoietic stem cells (HSC) in children with hematological malignancies without suitable matched donor. Ten children, median age 12 years (range, 3-17), were transplanted from haploidentical family donors for acute lymphoblastic leukemia (n = 4), acute myelogenous leukemia (n=2), chronic myelogenous leukemia (n = 2), non-Hodgkin lymphoma (n = 1) and myelodysplastic syndrome (n = 1). Parents were donors for nine, sibling for one patient. T-cell depletion of HSC was performed using CellPro followed by antiCD2/CD3 depletion in 7, and CliniMacs magnetic sorting in 3 grafts. Primary engraftment was achieved in nine patients. Patient with graft failure was successfully re-grafted. Primary acute GVHD was diagnosed in one patient who got higher amount of T-cells in the graft. Secondary GVHD was induced by add-backs of lymphocytes in four patients. Three patients developed chronic GVHD. Four patients died due to transplant related mortality (40%), one from veno-occlusive disease, two due to CMV pneumonia and one of aspergillosis with extensive chronic GVHD. Four patients relapsed with leukemia within 35-98 days post transplant, three without previous signs of GVHD, and all died. Two patients are alive and well 26 and 42 months after transplant. Haploidentical family donors appear to be a reasonable alternative option for patients with urgent indications for allogeneic transplant and/or without a matched donor.

A 59-yr-old man developed fevers, shortness of breath, persistent cough and weight loss, shortly after initiation of therapy with interferon-alpha 2a and cytosine arabinoside for treatment of chronic myelogenous leukemia. Radiologic pulmonary infiltrates and lung tissue biopsy were consistent with bronchiolitis obliterans organizing pneumonia (BOOP). After discontinuation of the chemotherapeutic drugs, the pneumonic symptoms and chest roentgenogram infiltrates resolved. This report suggests that treatment with interferon-alpha, in combination with cytosine arabinoside, may produce the rare complication of BOOP.

Intravenous busulfan (i.v. BU) has demonstrated safety when administered at 0.8 mg/kg per dose i.v. every 6 hours x 16 doses. We evaluated the safety and pharmacokinetics (PK) of giving the same total daily i.v. BU dose (3.2 mg/kg) either divided as a twice-daily infusion or as a single infusion to patients undergoing hematopoietic stem cell transplantation (HSCT). Twelve patients with hematologic malignant disease were treated; 7 patients had non-Hodgkin's lymphoma, 4 patients had acute myeloid leukemia, and 1 patient had chronic myelogenous leukemia. The first cohort (group A) received, on the basis of actual body weight, i.v. BU at 1.6 mg/kg per dose over 4 hours every 12 hours for 4 days (day -7 to day -4). The second cohort (group B) received 3.2 mg/kg per dose of i.v. BU (same total dose as group A) as a single infusion over 4 hours daily for 4 days. In both groups the i.v. BU was followed by cyclophosphamide 60 mg/kg daily for 2 days (day -3 and day -2). Blood specimens were collected on the first, fifth, and seventh doses for group A and on the first and fourth doses for group B to determine the disposition of i.v. BU. Peripheral blood stem cells (autologous in 7 cases and HLA-matched allogeneic in 5 cases) were given 2 days after completion of cyclophosphamide administration (day 0), and granulocyte colony-stimulating factor 5 microg/kg was started on the same day. GVHD prophylaxis consisted of tacrolimus plus methotrexate for recipients of allogeneic stem cells. One patient developed presumed fungal pneumonia and died of multisystem organ dysfunction on day +21 before hematologic reconstitution could be evaluated. Another was reported to have sudden death of undetermined cause at home on day 40. The remaining patients had engraftment (absolute neutrophil count >500/microL) at a median of 11 days and sustained platelet counts >20,000/microL at a median of 14 days. Significant regimen-related toxicity (grade III-IV) was limited to hepatic toxicity (2 cases) catheter infection (2 cases), epistaxis (3 cases), diarrhea (1 case), anorexia (1 case), mucositis (1 case), hyperglycemia (1 case), pneumonia (1 case), and sepsis (1). In group B there was 1 case of mild venoocclusive disease, which resolved without sequelae. No central nervous system or pulmonary toxicity was noted. Pharmacokinetic parameters, including clearance, half-life, maximum concentration, and area under the curve, demonstrated that the first dose profile was highly predictive of later dose PK profiles. No accumulation of the drug was noted. The change in dosing schedule did not increase toxicity or end-organ damage despite higher plasma concentration-times. Although further study for long-term efficacy is warranted, i.v. BU can be given safely with reproducible results on a twice-daily divided or single-daily dosing schedule to patients undergoing HSCT.
