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.

Seven cases of miliary tuberculosis in patients with hematologic disease were analyzed clinicopathologically. Mean age of the patients was 65 years, and the hematologic diseases were CML, AML, ALL, MDS and malignant lymphoma. Diabetes mellitus was present as a complication in three patients. Miliary tuberculosis was found in 5 cases during the first admission to our hospital owing to hematologic problems. In 4 of 6 cases, fever had started more than two months before admission, consequently, the tuberculosis probably began about that time. After admission, chemotherapy was administered in 5 cases, and steroid in 6 cases for hematologic disease. The mean total quantity of steroid administered was 2,134 mg of prednisolone and average treatment duration was 69 days. The chest roentgenographic shadow was so atypical that miliary tuberculosis was suspected in only one case. The initial chest roentgenogram showed hilar and mediastinal lymph node swelling as well as the shadow of pulmonary tuberculosis in two cases. It was thought that the hilar and mediastinal lymph node swelling could be explained by primary complex, although the patients were of advanced age, or by "secondary complex" reported by Terplan, K in 1940. The diagnosis of tuberculosis was made in two patients before their death by smear of aspirated fluid of cervical lymph node and by bone marrow cell block in one patients, and by pathological examination of mediastinal lymph node biopsy in the other patients. Tubercles were found from bone marrow cell block in 2 out of 5 patients and from bone marrow biopsy in 1 out of 3 patients, but the positive results were reported in 2 patients following death. Smears of sputum, gastric juice, urine, spinal fluid and pleural effusion were negative in all cases. One patient diagnosed as miliary tuberculosis also had pneumocystis carinii pneumonia. This case was treated with antituberculosis drugs for 20 days without improvement. Another patient diagnosed as miliary tuberculosis improved under treatment with antituberculosis drugs, but died of cytomegalovirus pneumonia. Autopsy in 5 cases revealed non-reactive miliary tuberculosis, and pulmonary hemorrhage probably due to DIC was present as a complication in two cases. In these cases, severe immunosuppression, which is a major precipitating factor of miliary tuberculosis, is thought to be induced by hematologic disease itself, chemotherapy, steroid or other underlying disease such as diabetes mellitus. Miliary tuberculosis in such compromised host is cryptic and progresses rapidly. Consequently, early diagnosis is very important. Retrospectively, the unexplained pyrexia was most important to suspect tuberculosis.(ABSTRACT TRUNCATED AT 400 WORDS)

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.

A 56-year-old female, who was diagnosed as CML in 1983 and had been well controlled with busulfan, was admitted to our hospital because of fever and iliac bone pain. Peripheral blood showed leukocytosis (WBC 70,000/microliters and bone marrow was normocellular with 53% leukemic cells, suggesting that she was in the blastic crisis. Chromosomal analysis of bone marrow cells at that time revealed t (9; 22; 12) and some additional abnormalities. The number of chromosomes ranged from 44 to 131 and the mode of chromosome number was 65. She was treated with combination regimen consisting of vincristine, 6-mercaptopurine and prednisolone and right iliac tumor was irradiated. Three months after admission, she died of DIC and pulmonary insufficiency due to leukemic infiltration.

Procoagulant activity of gastric cancer tissues and leukocytes obtained from various types of leukemia have been studied with special reference to TTP. The following results were obtained. Homogenates of APL leukocytes and gastric cancer tissues contained strong procoagulant activities, most of which have been identified as TTP since the activities were neutralized by a specific antibody against purified human placenta TTP, inactivated by the removal of phospholipid with heptane-butanol mixture, and inactivated by the addition of phospholipase C. The delipidated homogenates regained procoagulant activities by relipidation procedures. These results also confirmed that TTP from APL leukocytes and gastric cancer tissues have the same lipoprotein properties as those of TTP in normal tissues. Though slight proteolytic activity and fibrinolytic activity were demonstrated in the homogenate of gastric cancer tissues, it was noted that the TTP activity was different from these two activities by partial purification of TTP from gastric cancer tissues. The TTP activity of 9 homogenates of gastric cancer tissues was 301 +/- 289 (mean +/- SD) units per mg protein, being higher in homogenates of mucinous adenocarcinoma and signet-ring cell carcinoma than in those of tubular and poorly differentiated adenocarcinoma. The mean TTP activity of leukocyte homogenates from 14 patients with APL and one out of 4 patients with CML in blastic crisis was 81 +/- 76 units/10(7) cells. The TTP activity of the homogenates of leukocytes from 7 out of 18 patients with AML and another patient with CML in blastic crisis ranged from one to six units/10(7) cells with a mean of 3.3 +/- 1.2. The TTP activity of leukocyte homogenates from the other 11 cases of AML, two cases of CML in blastic crisis, 6 cases of CML, and one case each of ALL and CLL were less than one unit/10(7) cells. In leukemic patients, all cases with a value of more than 202 for the product of units of TTP activity per 10(7) cells and differential count (%) of leukemic cells in the bone marrow smear (MU value) were accompanied by DIC. The MU value of leukemic patients correlated well to the plasma fibrinogen and serum FDP levels. All patients with a MU value of more than 277 died of DIC when a sufficient amount of heparin was not administered. On the other hand, no DIC developed in any of the patients with a MU value of less than 90.(ABSTRACT TRUNCATED AT 400 WORDS)

A 66-year-old woman complained of chest discomfort in January 1995. In March the accelerated phase of chronic myeloid leukemia (CML) was diagnosed. Chromosomal analysis demonstrated negative Ph and positive t(9;16) (q34;p11) with positive major BCR/ABL chimeric mRNA. Administration of hydroxycarbamide was initiated, but in May she developed high fever and severe left hypochondralgia. Her WBC was 62,100/microliter (blast 64%), and LDH was 3,590 IU/l. Bone marrow examination showed 78.6% blasts, with a nucleated cell count of 74 x 10(3)/microliter. Blasts were negative for esterase stain and partially positive for both peroxidase stain and PAS reaction. Surface marker analysis revealed that blasts were positive for CD13, CD19, CD33, CD34, and HLA-DR. A diagnosis of blast crisis was made and she was treated with the VDS-CP regimen with heparin for DIC. After temporary improvement her disease recurred rapidly with severe DIC. Treatment with low molecular weight heparin and fresh frozen plasma failed to control DIC and she died of subarachnoid hemorrhage on the 48th hospital day. This is the first veprted of case Ph-negative, M-BCR/ABL-positive CML with t(9;16) accompanied by severe DIC.

Several new 4-(3,3-dimethyltriazeno)-5-benzamidopyrazole derivatives were prepared by reacting 4-diazo-5-benzamidopyrazole derivatives with dimethylamine. The compounds were tested at 10 microM for their vitro antileukemic activity against K562 (Human chronic myelogenous leukemia) and Raji (human Burkitt limphoma ) cell lines. Dacarbazine and methotrexate were used for comparative purpose. The 3-methyl-4-(3,3-dimethyltriazeno)-5-(substituted benzamido)pyrazoles, bearing the pyrazole nucleus free at 1 position, resulted more active than the 1-(substituted phenyl)-3-methyl-4-(3,3-dimethyltriazeno)-5-benzamidopyrazoles. Dacarbazine at 10 microM showed no activity in the above tests. The observed difference among Dacarbazine and the active 4-triazenopyrazoles migth be explained admiting that these last compounds, differently by Dacarbazine, did not follow a mechanism of action based on the cytochrome P-450 induced demethylation. The most active compound 2d showed growth inhibition values of 97.8 and 99.4% against K562 and Raji cell lines respectively. Methotrexate inhibition values at 0.2 microM against the above cell lines were 86.7 and 75.1% respectively.
