Thrombotic events have been reported in acute lymphoblastic leukaemia patients, especially during or after L-asparaginase administration. A so-called L-asparaginase associated coagulopathy has been well recognized, being characterized by a hypercoagulable state (decrease of antithrombin III, plasminogen, protein C, protein S and increase of prothrombin fragment F1 + 2, thrombin-antithrombin complexes and fibrinopeptide A). The aim of this study was to determine whether the supplementation of antithrombin III (AT-III) concentrates could improve the L-asparaginase associated coagulopathy, thereby blocking the activation of the haemostatic system. In 25 adult patients with acute lymphoblastic leukaemia (M 19, F6, mean age 34 years) antithrombin III (AT-III) concentrates were administered at daily doses of 50 U/kg for 10 consecutive days from the beginning of L-asparaginase therapy (6,000 U/m2/day s.c. for 7 days), given according to the GIMEMA ALL 0288 trial. A marked increase of antithrombin III was recorded on days IV-VIII-XI (P < 0.001). No changes in protein C, protein S, plasminogen, alpha 2-antiplasmin, factor VII and platelet count were observed and there was no increase in markers of hypercoagulability. There was no evidence of disseminated intravascular coagulation. In conclusion, AT-III concentrate supplementation during L-asparaginase therapy, by the achievement of high levels of antithrombin III, is associated with a lack of activation of the haemostatic system and appears to overcome the complex coagulopathy associated with L-asparaginase.

Three cases of acute lymphoblastic leukemia (ALL) with the rare t(17;19)(q22;p13) translocation were investigated for E2A/HLF fusion genes using reverse transcription coupled with polymerase chain reaction (RT-PCR). The patients had C-ALL, F/17 years (case 1) or pre-B ALL, M/11 years (case 2) and M/13 years (case 3). Case 1 had an event-free survival (EFS) of 42 months. Case 2 was ultimately refractory to treatment. Case 3 presented following EFS of 16 months in morphological remission (1% blasts), but with immunological and cytogenetic evidence of active disease, then relapsed, remitted and relapsed. Type II E2A/HLF fusion cDNA was found at diagnosis (cases 1, 2), at presentation (case 3) and in all samples tested, whether with active disease or in complete remission (CR). Case 3 showed, in addition, type I fusion E2A/HLF cDNA at presentation, through induction therapy when there was evidence of active disease, but not in CR. Cases 1 and 3 had bone marrow transplantation while in CR but with residual disease detectable by RT-PCR. All patients have died of ALL. Two cases (2 and 3) had hypercalcemia with bone lesions. No case had any evidence of disseminated intravascular coagulation. This is the first demonstration of the value of RT-PCR for the detection of minimal residual disease in t(17;19) ALL.

Haemorrhagic diathesis is the commonest cause of morbidity and mortality in acute leukaemias (AL). It is most commonly due to thrombocytopenia resulting from bone marrow failure. However, in a significant number of cases, disseminated intravascular coagulation (DIC) plays an important part. Previously it was thought that this mechanism was mainly confined to acute promyelocytic leukaemia (APL), but recently it has also been reported to occur in other subtypes of acute leukaemia. We report the results of a study carried out to find the incidence of DIC in various types of AL at the time of first diagnosis and in the absence of other recognisable causes. DIC was observed in 14(13.4%) cases out of 104 cases of AL studied. Nine out of 49(18.4%) cases of AML and 5 out of 55(9.1%) cases of acute lymphoblastic leukaemia (ALL) showed coagulation abnormalities consistent with DIC. Out of the 9 cases of AML showing DIC, 63 (66.67%) belonged to APL (FAB ME) subtype. Three (60%) out of 5 cases of ALL with DIC had T-cell immunophenotype. The results indicate that DIC may also occur in types of AL other than APL, particularly in T-ALL, and should be looked for.

We reported a 17-year-old girl with relapsed acute promyelocytic leukemia (APL) who achieved complete remission and has been received maintenance therapy with all-trans retinoic acid (ATRA). The patient was diagnosed as APL in 1986. The ANLL 861 protocol of the Children's Cancer and Leukemia Study Group induced complete remission, and the chemotherapy was discontinued in 1989. However, she suffered a relapse with APL in 1991 and begun receiving ATRA (30 mg/m2/day) therapy because of disseminated intravascular coagulation. Bleeding tendency was discontinued by day 5. During the treatment, the white blood cell count increased markedly to 35,510 per microliters on 15th day, however she achieved complete remission morphologically on day 18. After informed consent was obtained from the family, she has been given ATRA orally for more than three years at the time of this report. The pharmacokinetics examination (ATRA 20 mg/m2 single per os) was performed 12 and 22 months after the induction therapy. The each peak plasma level of ATRA was 89 and 149 ng/ml. The concentration of ATRA has yet reached a level despite the continuous ATRA therapy. We considered that it may be useful to monitor plasma levels of ATRA during the treatment.

Disseminated intravascular coagulation (DIC) is characterized by extreme activation of intravascular coagulation, and clinical manifestations such as bleeding and/or multiple organ failure is sometimes observed in advanced cases of DIC. The balance of coagulation and fibrinolysis activation varies according to the underlying diseases of DIC. DIC cases are classified as the type with predominant coagulation activation and the type with predominant fibrinolysis activation in former type plasma levels of thrombin-antithrombin III complex (TAT) are greatly increased, and those of plasmin-alpha 2 plasmin inhibitor complex (PIC) are slightly increased. In addition plasma levels of plasminogen activator inhibitor 1 (PA1) are greatly increased, multiple organ failure is a major clinical manifestation in advanced cases and sepsis is a representative underlying disease. In the second type both plasma levels of TAT and PIC are greatly increased, plasma levels of PA1 are almost within normal limits. Bleeding is a major clinical manifestation in advanced cases and acute promyelocytic leukemia (APL) is a representative underlying disease. The classification of DIC should be considered when choosing treatment with DIC. Diagnosis of pre-DIC status is based on gradually decreasing platelets counts in sepsis and on mild elevation of FDP and D dimer in APL, leukemia and cancer.

Eleven patients with chronic subdural hematoma (CSDH) with bleeding tendency (BT) were surgically treated in the last 12 years. To study the clinical problem of CSDH with BT, 11 surgical cases were divided into 3 groups, Group A; CSDH with primary BT (1 case of hemophilia A), Group B; CSDH with BT secondary to a basic disease (3 cases of leukemia, 2 cases of malignant tumor with DIC, 1 case of chronic renal failure and 1 case of liver cirrhosis), Group C; CSDH with BT by anticoagulants (warfarin) (2 cases of replacement of mitral valve, 1 case of A-C bypass). Evacuation of the hematoma was performed by means of one or two burr holes with irrigation of the hematoma cavity and a drainage tube was placed in the subdural space. The outcome was excellent in Groups A and C. In Group B, two patients with DIC due to gastric cancer and prostatic cancer died, and 3 patients with leukemia recovered dramatically from CSDH, but the poor course of the disease itself resulted in death. The outcome of other patients in Group B was excellent. Since CSDH with BT is often fatal, those patient had usually been treated conservatively. However, from this analysis, we stress that CSDH with BT should be surgically treated after checking the blood conditions carefully to determine whether or not the patient has need for surgery.

In 71 patients with acute leukaemia admitted for remission induction, disseminated intravascular coagulation (DIC) was looked for in 50 patients and diagnosed in 10 (20%). Of 10 patients with acute lymphoblastic leukaemia, 3 had DIC, and of 40 patients with acute myeloblastic leukaemia, 7 had DIC. The presence of DIC was related to bleeding manifestations within the first 2 weeks. A haemorrhagic diathesis was present in all DIC patients: 4 had minor and 6 had major bleeding, i.e. WHO grade > or = 2. In addition to blood product support, most DIC patients were treated with low doses of heparin and tranexamic acid. In all DIC patients the haemorrhagic symptoms preceded the heparin administration. Among 40 screened patients without DIC, 17 patients had minor and 3 had major haemorrhagic manifestations. Thus, the proportion of patients with major bleeding was significantly greater among the DIC patients (6/10 vs 3/40, p < 0.001). In conclusion, DIC at presentation was associated with a significantly increased risk for severe haemorrhagic complications and should be looked for in adults with acute leukaemia.

Plasma levels of thrombin-antithrombin III complex (TAT), plasmin-alpha 2-plasmin inhibitor complex (PIC) and active plasminogen activator inhibitor (PAI) were assayed in 66 cases of disseminated intravascular coagulation (DIC). Significant elevation of both TAT and PIC was observed in all cases of DIC. Most elevated levels of TAT were seen in DIC with acute promyelocytic leukaemia (APL) and sepsis. The highest levels of PIC were seen in DIC with APL but were much lower in sepsis. A significant elevation in active PAI was observed in DIC due to acute leukaemia (apart from APL), chronic myeloid leukaemia and sepsis, but not in APL, non-Hodgkin lymphoma and cancer. Active PAI was higher in patients with multiple organ failure (MOF) than in those without MOF while PIC was lower in patients with this complication. Thus, the balance of coagulation and fibrinolysis varied according to the underlying cause of DIC; APL had more dominant activation of fibrinolysis, while sepsis had greater activation of coagulation. It is suggested that the inhibition of secondary fibrinolytic activation plays an important role in the progression of MOF by the disturbance of the microcirculation.

Pathologies of serial sections of 9 temporal bones from 6 patients without caloric response were studied. The patients died of epipharyngeal cancer, middle ear cancer, chronic renal failure with DIC, pancreatic cancer with DIC, multiple brain metastasis of pancreatic cancer, and leukemia. Under light microscopy, 8 ears showed pathologies in the vestibular end organs and the nerves. Possible causes of the lack of caloric responses in the 8 ears were endolymphatic hemorrhage, labyrinthitis, leukemic infiltration in the labyrinth, degeneration or disappearance of the vestibular sensory cells, reduction in the number of vestibular nerve fibers, and/or brainstem lesions. The remaining one ear did not show abnormal findings in the vestibular end organs or the nerves, but the patient had brainstem lesions. Four types of temporal bone pathologies were observed according to the lesion site responsible for the lack of caloric response; i) sensory type, ii) neural type, iii) mixed type and iv) central type.

From 1977 to 1990, 40 cases of bone marrow necrosis (BMN) were diagnosed among 10,856 (0.37%) consecutive bone marrow aspirations performed alone or with biopsy. All but two patients had underlying malignancies. Leukemia, nasopharyngeal cancer and cancer of unknown origin were the most common underlying diseases. Severe bone pain and fever were the predominant presenting symptoms. Anemia, schistocytes and leukoerythroblastosis were noted in the peripheral blood smears in 97% (37/38), 72% (22/32), and 66% (23/35) of the patients with cancer and BMN. Malignant cells were found in bone marrow aspirates or biopsy specimens in all but one of the patients. Varied degrees of disseminated intravascular coagulation were demonstrated in all of the 10 patients examined who displayed coagulation status. Four of seven patients with leukemia achieved complete remission after chemotherapy, and the survival time for the complete responders ranged from 10 months to eight years. The outcome of cancer patients with BMN who did not respond to chemotherapy was poor, with a median survival time of six weeks.
