A 24-year-old woman with chronic granulocytic leukemia and alveolar proteinosis required extracorporeal membrane oxygenator support for respiratory failure refractory to conventional therapy. During perfusion, each lung was lavaged with 10 L. of normal saline. The lavage led to marked clearing of the lungs and improvement in pulmonary function. Extracorporeal support was terminated successfully after 54 hours. The patient died 2 weeks later with bone marrow insufficiency and overwhelming sepsis. Pulmonary lavage is technically feasible during venovenous oxygenator bypass, and may be of value, since such lavage debrides alveoli as well as the bronchial tree. Because pulmonary lavage provides a possible means of improving pulmonary function, it seems worthy of consideration as an adjunct to membrane oxygenator support.

We examined the changes in plasma levels of endothelin-1 (ET-1), a potent vasoconstrictor peptide, in 47 cases of disseminated intravascular coagulation (DIC) to investigate the role of ET-1 in DIC and its relation to multiple organ failure (MOF). A significant elevation of plasma levels of ET-1 was observed in some cases of DIC, especially in patients with sepsis, blastic crisis of chronic myelogenous leukemia, and cancer. However, no such significant elevation was observed in patients with acute promyelocytic leukemia (APL), acute leukemias except for APL, or non-Hodgkin lymphoma. Plasma levels of ET-1 were higher in patients with DIC with MOF than in those without MOF. Although the levels of ET-1 were decreased or remained low with clinical improvement in most DIC patients, the levels were further increased or remained high in patients who showed no improvement in DIC. It is suggested that ET-1 must play an important role in further progression of MOF with the vasoconstriction and microcirculatory disorders.

Bone marrow transplantation from an HLA-identical sibling is increasingly used as a curative therapy for patients with hemopoietic stem cell disorders including acute leukemia, chronic myelogenous leukemia and severe aplastic anemia. Between March 1983 and March 1991, we performed 86 cases of allogeneic bone marrow transplantation (BMT) for the patients with hemopoietic stem cell disorders: 25 acute myelogenous leukemia (AML); 15 acute lymphoblastic leukemia (ALL); 20 chronic myelogenous leukemia (CML); and 26 severe aplastic anemia (SAA). Ten out of 25 AML are in disease free survival (DFS). The causes of death were recurrence of leukemia (12), acute GVHD (3), sepsis (1) and veno-occlusive disease (1). Nine of 15 ALL are in unmaintained remission. Thirteen out of 20 CML are in DFS. Among 26 SAA, 21 are enjoying DFS, but 1 died of engraftment failure, 3 of graft rejection followed by cytomegalovirus (1) and aspergillus pneumonia (1). Comparing the survival between standard [less than or equal to CR1: 9/14 (64%)] and high risk [greater than or equal to CR1: 1/11 (9%)] AML, our data suggest that preparative regimen for high risk AML was not potent enough to eradicate the minimal residual disease in advanced AML. Although our cases are limited and the follow-up period is short, our result of ALL [overall: CCR (60%), standard risk (adult less than or equal to CR1, children less than or equal to CR2; 8/11 (73%) and high risk; 1/4 (25%)] and CML [overall: 65%, CP; 9/10 (90%), AP; 4/6 (67%), BP; 0/4 (0%)] are optimistic. It is of our interest that the incidence of death related with IP (1/33: 3%) and with AGVHD 94/33: 12%) were much less than that of other's observation but the explanation for this still remains to be clear.

Twenty-one patients (median age = 34, range = 10-49; F:M = 7:14) received a preparative regimen consisting of busulfan 4 mg/kg/day x 4, cytosine arabinoside 2 g/m2/12 h x 4 and cyclophosphamide 60 mg/kg/day x 2 ('BAC' regimen) for allogeneic bone marrow transplantation. Out of 12 patients with acute myeloid leukemia (AML), two were in first remission, six were in second remission and four had resistant, relapsed disease or prolonged marrow aplasia after induction chemotherapy. Five of the 12 patients with AML had secondary AML. Four patients had transfusion-dependent myelodysplastic syndrome. Three patients with chronic myeloid leukemia were in the accelerated phase and two were in the blastic phase. Organ toxicities related to the preparative regimen were graded. Liver toxicity occurred in 11 patients, two of these were fatal veno-occlusive disease (VOD) (10%). Nineteen of the 21 patients had grade 2 or less diarrhea, and 13 also had mucositis. One patient developed grade 3 cardiac toxicity, and one other patient had grade 1 skin toxicity. Four patients had gross hematuria related to treatment (19%). No renal, pulmonary or CNS toxicities were encountered. Ten patients have died, two from regimen-related hepatic VOD. Of the remaining eight deaths, four were from respiratory failure in four patients (one case each of Pneumocystis pneumonia, CMV pneumonia, bronchiolitis obliterans associated with chronic graft-versus-host disease, and interstitial pneumonitis complicated pulmonary emboli), and one patient each from GI bleeding, cardiac arrhythmia, sepsis and CNS bleeding. Thus far, only one patient transplanted for secondary AML in second remission relapsed at day 230.(ABSTRACT TRUNCATED AT 250 WORDS)

Ten patients with severe hematologic malignancies (four with acute leukemia, three with multiple myeloma, one with prolymphocytic leukemia, one with malignant lymphoma and one with blastic crisis of chronic myelogenous leukemia) developed respiratory failure during the period between April 1986 and May 1990. Clinically, the patients manifested high-fever, dyspnea refractory to oxygen therapy, diffuse pulmonary rales and severe hypoxemia without evidence of cardiogenic pulmonary edema. Chest roentgenograms displayed diffuse alveolar infiltrates. Respiratory failure occurred as early as 48 hours and as late as 66 days after the administration of intensive anti-neoplastic chemotherapy. At that time leukocyte count was between 100/microliters and 54,900/microliters. Marked leukocytosis was observed in two patients with AML and PLL. Respiratory failure was preceded by sepsis in one patient with AML and by pneumonia in nine patients. DIC was diagnosed in four patients. All patients treated with high dose methyl prednisolone (mPSL) within 12 hours after the onset of respiratory failure. Only one patient required assisted ventilation. High dose mPSL had significant effect on seven of ten patients. But three patients died from progressive respiratory failure, sepsis, pneumonia and multi-organ failure.

At the Clinic for Hematology of the Military Medical Academy in Belgrade two patients had been treated from November, 1983 to July, 1986, in whom the existence of chronic myelogenous leukemia (CML) was established with negative Ph'-chromosome, as well as the existence of acquired partial erythrocyte aplasia (APEA). In the male patient of 58 years of age and the female patient of 71, APEA was established at the same time as CML. The maladies showed to be refractory to antileukemia (busulfan, hydroxyurea) and immunosuppressive (corticosteroid, androgen) therapy in both of the patients, while in the first patient splenectomy was also without effect on the course of the disease. Serumal inhibitors of erythropoiesis were not registered. After 18 months of disease duration one patient had a blastic transformation of CML into acute myeloblastic leukemia (AML) of the M1 form, and death appeared under the clinical manifestation of sepsis during iatrogenic aplasia of the bone marrow. The other patient died 32 months after start of illness because of intracranial hemorrhage, without signs of HML metamorphosis. In the discussion, previous illnesses are considered--kidney tuberculosis and polyarthralgias--as well as the applied treatment of these illnesses (antituberculotics and nonsteroid antirheumatics) as possible etiological factors in the appearance of APEA. The mutual link between APEA and CML, though exceptionally rare, is possible, and erythroblastopenia can precede or occur simultaneously with CML or during its treatment. APEA is usually the sign of CML terminal metamorphosis into acute leukemia, though it sometimes coexists with CML as an independent malady.

Based on in vitro evidence of time-dependent synergistic kill of HL-60 leukemia cells exposed to Ara-C and mitoxantrone, 44 patients with relapsed or refractory AML and 3 with blastic CML were treated with a timed sequence of both drugs. There were 25 females and 22 males, with a median age of 53 (range 21-75). Of 31 patients with relapsed AML, 24 had one prior remission, 6 had two and 1 had three. Of these, 15 had failed a second reinduction attempt. Thirteen patients were primarily refractory to induction with Ara-C plus daunorubicin. Each dose of Ara-C, 500 mg/m2, was followed after 6 hr by mitoxantrone, 5 mg/m2, and the sequence was repeated four to six times (44-68 hr) in different cohorts of patients. All but two patients (one with blastic CML and one in relapse and refractory) are evaluable for response and toxicity. Of 16 patients in relapse without prior reinduction 7 achieved CR and 3 PR (62% response rate); there were 3 CR in the 14 patients who were in relapse and refractory (21% response rate) and 4 CR and 1 PR (35% response rate) in the 14 patients with primary anthracycline resistance. Five of seven patients previously exposed to mitoxantrone achieved CR. Response lasted from 2 to 42 months, with two patients alive and in continuing remission at 34 and 42 months. Average marrow recovery was seen after 25 days and time to remission was 30 days. Six patients died in induction (four from sepsis and two from the tumor lysis syndrome) and 21 had progressive disease. Chemotherapy was well tolerated with minor nausea and vomiting in 13 patients, moderate in 20, and severe in 2. Most patients did not have evidence of drug-induced mucositis: it was minor in 9 and moderate in 2. Renal dysfunction was attributable to the use of nephrotoxic antibiotics. Hepatic dysfunction was reversible and was minor in 10 patients, moderate in 13, and severe in 3. Sequential, timed administration of intermediate-dose Ara-C and mitoxantrone is an active and well-tolerated antileukemic regimen.

There is no general agreement about the effect of an enlarged spleen on the outcome after bone marrow transplantation (BMT) for chronic myeloid leukaemia (CML). In this retrospective analysis, we compared rate of engraftment, haematological recovery and survival in 42 CML BMT recipients, 19 with splenomegaly and 23 without. Other variables analysed included interval from diagnosis to BMT, disease status at BMT, conditioning regimen, additional splenic irradiation, marrow cell dose, donor recipient ABO match and graft-versus-host disease. In multivariate analysis, the only significant variable was the presence or absence of splenomegaly. Splenomegaly was significantly correlated with delayed engraftment and graft failure. Patients with delayed engraftment experienced higher mortality, largely due to sepsis. These results emphasize the adverse impact of splenomegaly upon BMT survival in CML, and suggest that splenic irradiation does not favourably affect the early outcome after BMT.

The retrospective study of acute renal failure (ARF) in patients with hematologic neoplasms was carried out. ARF occurred in 32 (6.1%) of 526 patients with hematologic neoplasms. Twenty-one (66%) patients recovered from ARF, but only 7 (22%) survived and were discharged from the hospital and 25 (78%) died of ARF or other complications. In 17 patients with leukemia or malignant histiocytosis, sepsis and/or disseminated intravascular coagulation were the most common causes of ARF, and all 17 patients died. In 11 patients with multiple myeloma, ARF was always attributable to the underlying disease, and the clinical course improved with the initiation of blood purification therapy (hemodialysis, plasma exchange) and chemotherapy. Five patients in blast crisis of chronic myelogenous leukemia or non-Hodgkin's lymphoma developed ARF as a result of tumor lysis syndrome. In this group, renal function improved with hemodialysis but only 2 patients survived. Patients with oliguria had worse outcomes than those without oliguria. Survival appeared to depend not on renal function but on the underlying disease, the cause of ARF, and other complications. These findings suggest that, in patients with hematologic neoplasms complicated by ARF, early initiation of blood purification therapy will improve the prognosis.

In the present study plasma fibronectin levels were determined in patients with hematopoietic malignancy, particularly leukemias, in an effort to clarify their clinical implications. Among leukemia patients, those with AML, ALL, ATL or CLL had various plasma fibronectin levels that were higher in some cases, while lower in others, as compared to normal control values. An elevation of the fibronectin level was noted often in APL, while lower fibronectin values were observed in many instances of CML. In these types of leukemia, acute exacerbation as well as supervention of infection tended to be associated with lower than normal levels of fibronectin. An especially marked depression of fibronectin occurred, when leukemia was complicated by sepsis or DIC, in which a good parallel was noted between the progress of disease and the fibronectin level. In lymphoproliferative diseases, the fibronectin value varied widely, but low fibronectin levels were frequently associated with intercurrent infection or an extreme deterioration of the general physical conditions.
