A 60-year-old Japanese woman was admitted to our hospital because of fatigue, weight loss and abdominal distension. Myelofibrosis was diagnosed, based on anemia, huge hepatosplenomegaly, leukoerythroblastosis and bone marrow fibrosis. Following treatment with ranimustine, anemia and splenomegaly improved. Seven months after initial therapy of ranimustine, however, polycythemia (RBC 7.39 x 10(6)/microliter; Hb 19.1 g/dl, Ht 65.9%) developed gradually, then RBC decreased to normal level following venesection (total 1,200 ml). After 32 months, blastic transformation occurred. The blasts were negative for myeloperoxidase. By flow cytometric analysis, the cells were positive for CD2, CD13, CD33 and HLA DR. Thus, AML (M0) was diagnosed. Despite of treatment with multicytotoxic agents, she died of DIC 36 months after the initial diagnosis of myelofibrosis. The progression from myelofibrosis to polycythemia is rare and only 15 cases have been reported so far. In addition, although a chromosomal abnormality, 46, XX, t(3; 12) (q25; p11), was present at the time of first diagnosis of myelofibrosis, the development of an additional abnormality, del(11) (q-), might be related to the transformation to AML.

We describe an extremely rare case of granulocytic sarcoma of the porta hepatis causing obstructive jaundice. The patient was an 84-year-old man admitted because of obstructive jaundice. Ultrasonography (US) and computed tomography (CT) scanning of the abdomen disclosed a mass about 2.5 cm in diameter near the neck of the gallbladder, and thickening of the gallbladder wall. Based on these findings, gallbladder carcinoma was suspected. After endoscopic retrograde biliary drainage (ERBD) was performed, the jaundice resolved. However, blast cells were detected in the peripheral blood 51 days after admission, and laboratory studies disclosed acute myelocytic leukemia (AML: French-American-British [FAB] type M0). We treated him conservatively, with antibiotics and ERBD but he died of disseminated intravascular coagulation. Autopsy showed that the suspected gallbladder carcinoma was actually a granulocytic sarcoma arising in association with AML and causing obstructive jaundice. The largest tumor involved the porta hepatis. It should be kept in mind that granuloctyic sarcoma is a possible cause of obstructive jaundice, even in patients with no evidence of AML.

Among 379 patients with AML with FAB type M1, 2 and M4-7 diagnosed between 1978 and 1997 in our institution, 19 (5%) had hypofibrinogenemia (HF), ie a fibrinogen level <180 mg/dl. Compared to patients with normal fibrinogen (n = 360) patients with HF had significantly elevated markers of activation of coagulation (TAT, F1.2, FPA) and fibrinolysis (D-dimer, FDP) indicating that disseminated intravascular coagulation/hyperfibrinolysis was the cause of hypofibrinogenemia. Patients with HF had significantly longer prothrombin times, thrombin clotting and reptilase times. Factor X and VIII were significantly lower than in patients without HF. With the exception of M7, HF occurred in all FAB subtypes, but was most common in M5 (12.1%). Patients with HF did not differ from those with normal fibrinogen with regard to age, sex, leukocyte count and other hematological parameters. During induction chemotherapy fibrinogen normalized rapidly (median 5 days) and there was no increased incidence of early hemorrhagic death. The overall and disease-free survival was similar to that of patients without HF.

To know the clinical characteristics and the prognostic factors of hyperleukocytic acute leukemia, we reviewed 244 patients with acute leukemia associated with hyperleukocytosis. Restrospective analysis and control study were used. Hyperleukocytosis occured in 8.5% of patients with acute leukemia. Hyperleukocytosis in ALL was more common than that in AML. Among AML with hyperleukocytosis, M5 subtype was the most. Hepatomegaly, splenomegaly, lymphadenopathy, DIC and CNSL were more frequent in hyperleukocytosis group. The complete remission rate was 41.4% for patients with hyperleukocytosis versus 54.2% for patients with non-hyperleukocytosis. The early mortality rate was significantly increased in hyperleukocytic patients (23.8%) as compared to the nonhyperleukocytic group (11.1%). Intracranial hemorrhage was the main cause of early death. The high risk factors of early death were: hemoglobin < or = 40 g/L, blood platelet < or = 30 x 10(9)/L, DIC, infection, CNSL at presentation. Acute leukemia with hyperleukocytosis has poor prognosis. Especially, acute myeloid leukemia with hyperleukocytosis must be taken seriously because of high early mortality rate.

Coagulation disorders are often the reason for fatal bleeding in acute promyelocytic leukemia. Their occurrence as well as pathogenesis and prognostic significance in other subtypes of acute myelogenous leukemia and acute lymphoblastic leukemia is less known. Tests were carried out in 70 patients including 49 with AML and 21 with ALL. In all patients thrombin-antithrombin complexes (TAT), D-dimer (DD) and plasmin-antiplasmin complexes (PAP), antithrombin III activity, fibrinogen/fibrin degradation products, APTT and PT were determined. The tests were performed on diagnosis and after cytostatic treatment. The level of TAT, DD and PAP was elevated in 83% of the patients on diagnosis and in 90% after treatment. The highest values were observed in AML M3 patients. Among leukemic patients with normal levels of TAT, DD and PAP at diagnosis, cytostatic treatment had a negligible effect on the level of these markers. During remission the levels of these markers returned to the normal values while in patients without remission they were either elevated or returned to normal values. No correlation between the levels of activation markers and remission rate was reported. DIC was diagnosed in 13 patients including three after chemotherapy. The DIC was acute or subacute in AML and chronic in ALL patients. In the majority of acute leukemia patients there were already changes on diagnosis indicating coagulation activation. Except for AML M3, these usually had a subclinical course. The TAT, DD and PAP tests are not reliable markers of remission in acute leukemias.

From January 1990 to August 1997, 29 consecutive patients were treated with newly diagnosed primary acute promyelocytic leukemia (APL) at the authors' Institution. Of these, 27 (16 boys and 11 girls) were evaluable. Median age at diagnosis was 6.3 (range: 1.9-15.7) years. This population was treated with two consecutive protocols: 13 patients were included in the AML-HPG-90 protocol and 14 in the AML-HPG-95. The initial treatment was the same for both protocols: an induction 8-day phase with cytarabine, idarubicin, and etoposide was followed by a consolidation with cyclophosphamide, cytarabine, 6-mercaptopurine, vincristine, doxorubicin, and prednisone. Two courses of intensification with high-dose (HD) cytarabine and etoposide were given in the first study. Only one intensification course was administered in the second study, with HD cytarabine plus idarubicin or etoposide decided by randomization. Complete remission was achieved in 67% (18/27) of cases. Mortality on induction was quite high, 30% (8/27) mainly due to hemorrhages from disseminated intravascular coagulation (DIC). The event-free survival estimate for all patients was 0.47 (SE: 0.1). From April 1994, all-trans-retinoic acid (ATRA) was administered just during the first days of the induction phase (median: 9, range: 2-27) to stop or prevent DIC. Eighteen patients received ATRA and 9 did not. Three patients developed signs of ATRA syndrome during the first days of administration but no one died due to this toxicity. The impact of a short course of ATRA on early control of DIC was studied by analyzing the number of platelet, cryoprecipitate, and fresh frozen plasma transfusions during the induction phase in both groups. No statistical differences in complete remission rate, early mortality, need of transfusion of blood components for DIC, and survival estimates could be established between patients who received ATRA and those who did not. ATRA used in a short-course schedule during induction of APL did not stop early mortality due to DIC. Moreover, survival results did not improve with this method of ATRA usage. Longer periods of ATRA administration during APL therapy are strongly recommended.

A 16-year-old Chinese girl presented with AML-M5a. A bone marrow examination showed that the myeloblasts which were overwhelming the marrow contained giant granules (pseudo-Chediak-Higashi anomaly). Her karyotype showed a rare translocation t(10; 11)(p13; q14). Molecular delineation of the translocation breakpoints was not possible. Nonetheless, this case further demonstrates the morphological and phenotypic heterogeneity of acute leukaemia with this translocation. In this girl it was associated with disseminated intravascular coagulation.

A 71-year-old man with acute myelogenous leukemia (AML, M2) developed signs of chest oppression, and was diagnosed as having acute myocardial infarction (AMI). At the same time, his leukemia relapsed in association with disseminated intravascular coagulation (DIC). The patient's risk factors for AMI were hyperlipidemia, hyperglycemia, and a history of smoking. Coronary angiography showed occlusion of the circumflex branch. Percutaneous transluminal angioplasty (PTCA) was performed successfully, followed by administration of heparin. After chemotherapy, the patient's DIC improved and a second remission was attained. When elderly patients with AML show evidence of DIC, we should be aware of AMI as a possible complication. PTCA is a safe operation for such patients.

This clinical-pathological conference took place at the Sourasky Medical Center, Tel Aviv, on February 21, 2001. We present the case of a young and previously healthy soldier who developed multi-organ failure with predominant liver dysfunction following exertional heatstroke. The patient's clinical course consisted of an early phase of transient encephalopathy, associated with hyperthermia, hypophosphatemia, mild laboratory indications of renal failure, rhabdomyolysis and consumption coagulopathy. Following an intermediate convalescing phase that lasted a single day the patient deteriorated into a catastrophic course with hemodynamic instability, fulminant hepatic failure, respiratory distress, kidney failure, rhabdomyolysis, coagulopathy and coma. He died 4 days later. In this article we elaborate on the association of heatstroke with multiple organ dysfunction syndrome in general, and fulminant liver failure in particular. The nature of hypophosphatemia and the possible role of additional injury from acetaminophen are discussed.

Protein C, protein S, and antithrombin III were measured in 35 patients with acute leukemia (13 with AML and 22 with ALL). Low levels of proteins C and S were present in 15 (42.9%) and 20 (57.1%) patients, respectively, and 6 patients had low levels of antithrombin (ATIII). Seven patients also had DIC at presentation. There were no significant differences in the levels of protein C, protein S, and ATIII in patients with or without DIC. Twenty patients were available for re-evaluation at the end of induction therapy. The low levels of protein C and ATIII found at diagnosis had risen to normal levels at the end of the induction therapy, while low =levels of protein S remained in 75% of the patients. One patient with low protein C at presentation developed myocardial infarction on day 15, and another patient died of progressive neuropathy. No other thrombotic manifestations were seen. Whether the low protein C, protein S, or antithrombin levels predispose patients with acute leukemia to thrombosis in the absence of DIC is not known.
