A 22 year old female developed preeclampsia with fetal death in utero. After cesarean section she developed uterine inertia and acute hemorrhagic anemia complicated by sepsis, disseminated intravascular coagulation and total anuria for 4 weeks. She was treated with hemodialysis. The second patient, a 49 year old man developed sepsis and intravascular coagulation after a dog bite. Acute renal failure with a 3 week total anuria followed. He was initially treated with peritoneo dialysis. Renal biopsy showed evidence of renal cortical necrosis in both patients.

Intrauterine death of one twin in monochorionic pregnancies is associated with increased mortality and morbidity for the survivor. This has been attributed to the consequences of intrauterine disseminated intravascular coagulation (DIC) initiated by the dead twin. We describe a case in which the fetal cerebral and renal lesions typically found in survivors occurred without any derangement in coagulation. Instead, acute twin-twin transfusion was suggested by the presence of severe anemia in the surviving fetus at delivery. We suggest that the lesions frequently found in the survivors are often due to acute hemodynamic and ischemic changes resulting from acute twin-twin transfusion at the time of intrauterine death, rather than to late-onset DIC. This hypothesis has an important implication for future management: Intervention must occur before intrauterine death if neurologic sequelae in the survivor are to be prevented.

A prostate biopsy was carried out in a 53-year-old male outpatient with disseminated prostatic carcinoma. Two days later, he was admitted with severe acute anaemia (haemoglobin: 48 g.l-1) and macroscopic haematuria. Biological investigations revealed a disseminated intravascular coagulation (DIC). Symptomatic treatment was undertaken (transfusion of packed red blood cells, platelets, fresh frozen plasma and fibrinogen). However, the patient's condition worsened, and he was admitted to the intensive care unit 48 h later. Despite appropriate symptomatic treatment, the patient's condition continued to worsen. The prostatic origin of this condition was therefore suspected, and anti-androgenic treatment was started on day 9 (1,200 mg.day-1 ketoconazole and 2,000 mg.day-1 sodium fosfestrol). Within 48 h, the patient had began to recover in quite a spectacular manner. Ketoconazole starts blocking steroid synthesis within 4 h of giving it. This treatment can be used until oestrogen therapy starts having an effect (about one week). The low levels of testosterone in this case, before starting treatment, suggest that ketoconazole acted on the DIC by a possible cytotoxic effect on the carcinomatous cells.

Eighty-two women whose pregnancy was complicated by anemias of varying severity and twelve healthy pregnant women were examined. Blood plasma immunoglobulins A, G, and M were measured by immunochemical methods, as were the immune complexes of various levels and some parameters of the homeostasis system. The findings evidence a noticeable elevation of the concentrations of all immunoglobulins, of low-disperse immune aggregates in severe anemia of pregnancy, as well as intensive synthesis of immunoglobulin M in the fetus, low level of large immune complexes, and stimulation of some homeostasis components that results in consumption coagulopathy and chronic DIC syndrome. Correlations between some parameters of the blood coagulation and fibrinolysis systems, on the one hand, and humoral immunity characteristics, on the other, may be traced, among these correlations being reverse correlations between IgG level, activated recalcification time, fibrinogen concentration, and activated partial thromboplastin time.

Platelet counts were evaluated in 714 patients with advanced non-small cell lung cancer (N-SCLC), small cell carcinoma of the lung (SCCL), and colon cancer entered to a clinical trial. Patients had not received prior chemotherapy. Platelet counts were not different in patients who had received radiation therapy prior to entry to the study. In comparison to the other tumor types, patients with N-SCLC demonstrated an increased prevalence of thrombocytosis (counts greater than 400,000/mm3), higher platelet counts at the time of entry to the study, higher over all mean platelet counts, relative preservation of high platelet levels during disease progression, and no relationship between platelet numbers and the amount of chemotherapy given. By contrast, platelet counts in patients with SCCL were negatively correlated with the absolute amount of cyclophosphamide and adriamycin given, and declined most dramatically with disease progression and death. Platelet numbers did not correlate with fibrinopeptide A or fibrin split product levels suggesting that disseminated intravascular coagulation or fibrinolysis may have had less influence on platelet numbers than certain other factors. By contrast, significant correlations were found for all three tumor types between platelet numbers and other indicators of bone marrow function including anemia, total leukocyte count, and absolute neutrophil count; and the fibrinogen level. Based upon these findings, we postulate that the host response to malignancy, possibly in the form of production of bone marrow-stimulating cytokines, may play a prominent role in regulation of platelet counts in these (and perhaps other) neoplasms, and that a particularly prominent and persistent degree of marrow stimulation exists in patients with N-SCLC.

The plasma kallikrein-kinin system is activated in Gram-negative sepsis and typhoid fever, two diseases in which bacterial products have been shown to initiate inflammation. Because a single intraperitoneal injection of bacterial cell wall peptidoglycan-polysaccharide polymers from group A steptococci (PG-APS) into a Lewis rat produces a syndrome of relapsing polyarthritis and anemia, we investigated changes in the role of the kallikrein-kinin system in this model of inflammation. Coagulation studies after injection of PG-APS revealed an immediate and persistent decrease in prekallikrein levels. High-molecular-weight kininogen levels decreased significantly during the acute phase and correlated with the severity of arthritis. Factor XI levels were decreased only during the acute phase. Antithrombin III levels remained unchanged, indicating that neither decreased hepatic synthesis nor disseminated intravascular coagulation caused the decreased plasma contact factors. Plasma T-kininogen (an acute phase protein) was significantly elevated during the chronic phase. PG-APS failed to activate the contact system in vitro. Thus the kallikrein-kinin system plays an important role in this experimental model of inflammation, suggesting that activation of this system may play a role in the pathogenesis of inflammatory bowel disease and rheumatoid arthritis in which bacterial products might be etiologically important.

Malaria must be included in the differential diagnosis of all febrile patients. Malaria is classified 'complicated' or 'uncomplicated', according to clinical findings (cerebral malaria, generalized convulsions, pulmonary edema, severe anemia, hyperthermia, renal failure, haemoglobinuria, shock, spontaneous bleeding) and laboratory results (parasitemia greater than 5%, haemoglobin less than 5 g%, creatinine greater than 265 mumol/l, glucose less than 2.2 mmol/l, DIC, pH less than 7.2, bilirubin greater than 50 mumol/l). Plasmodium (P.) vivax, P. ovale and P. malariae cause uncomplicated disease as a rule, whereas P. falciparum may result in either of both. Complicated falciparum malaria is always at risk for a lethal outcome. Only microscopic evidence of malaria parasites proofs the diagnosis. The thick smear is good for screening, thin films are necessary to determine the species. Serology and cultures are not helpful in diagnosing acute malaria. Tests for drug resistance await to be applicable for emergency situations.

The paraneoplastic syndrome (PNS) is an association of symptoms and signs not directly related to the site or local manifestations of a malignant tumor or its metastases. Hematologic abnormalities as PNS include erythrocytosis, anemia, neutrophilia, neutropenia, eosinophilia, thrombocytosis, thrombocytopenia, venous thromboembolism and disseminated intravascular coagulation (DIC). These abnormalities are, by and large, due to the production of biologically active growth factors, hormones or as yet unidentified "humors" by the tumor. As our understanding of growth factors controlling hematopoiesis has increased in recent years, the biologic basis of hematologic PNS are better understood. For instance, tumor-associated neutrophilia is now known to be caused by the production of G-CSF by the tumor. The mechanism by which tumor causes thromboembolism have also been extensively investigated. Cancer cells induce platelet aggregation both in vitro and in vivo. Platelet aggregating material has been isolated and partially characterized from tumor cells. The involvement of platelet glycoprotein II b/IIIa in the tumor-platelet interaction has also been shown. Malignant cells contain a unique procoagulant, cancer procoagulant A, that directly activates factor X. Together with tissue factor, this procoagulant appears to have been contribute to a high incidence of thromboembolism in cancer patients. Better understanding of hematologic PNS is important for clinical care of the patients with cancer.

Reported are 2 cases of an advanced gastric cancer with a "diffuse carcinomatosis of the bone marrow" (DCMB) showing a widespread osteoplastic bone metastasis. In a DCBM, a widespread invasion of cancer cells to the bone marrow occurs, causing leukoerythroblastosis, anemia, and disseminated intravascular coagulation. The local reaction in the bone, namely being osteoplastic or osteolytic, has not been discussed in previous papers. Our cases were characterized by an extremely high serum alkaline phosphatase, a "superscan" view of the bone scintigram, and a diffuse osteoplastic bone metastasis with an osteoid increase. Thus we think there are DCBM subtypes with a diffuse osteoplastic bone metastasis.

The Hellp syndrome defined as the association of micro-angiopathic haemolytic anemia, hepatic cytolysis and thrombocytopenia, correspond to a severe form of gravidic toxemia, combined to manifestations of classic-pre-eclampsia. This retrospective study, conducted over 6 years, concerns 9 cases of Hellp syndrome, including 2 occurring during the immediate post-partum. Only cases where this biological triad was obvious and not associated with manifestations of disseminated intravascular coagulation, were considered in this study. In addition to the usual criteria of gravidic toxemia, the early clinical manifestation occur, in this study, between 28 and 38 weeks of amenorrhea and gastrointestinal manifestations are predominant. The physiopathogenic hypotheses of this syndrome remain variable and management varies depending on the authors. Treatment is that of pre-eclampsia. Medical treatments (steroids, heparin, immunosuppressants,...) are discussed, but severe feto-maternal complications require, most of the time, a surgical approach, depending on the number of pregnancies, the obstetrical conditions, the stage of the pregnancy and the severity of the syndrome.
