A case of a 21-year-old woman with Weber-Christian disease, associated with consumption coagulopathy and adequately controlled over the past year or more by corticosteroid and heparin therapy, has been described. Through the study on this case, it was concluded that a hemorrhagic diathesis complicating Weber-Christian disease, at least in advanced cases, was characterized by consumption coagulopathy associated with enhanced blood coagulability which arises from hyperlipemia due to abnormal lipid metabolism and further, that the consumption coagulopathy was modified by diminished synthesis of clotting factors and activation of the fibrinolytic system due to the secondary hepatic impairment. It might also be likely that systemic vascular changes contribute to the activation of the clotting system as a trigger of clotting factor consumption. The complex pathophysiology of a hemorrhagic diathesis in this disease seemed to be brought about by a complex combination of such a variety of factors. In addition, decreased erythrocyte sedimentation rate observed characteristically during hemorrhage might probably have a direct correlation with hypofibrinogenemia due to consumption coagulopathy in advanced cases.

This rare fatal disease of infants and early childhood occurred in seven children from four families. Six children died during 2-4 weeks from the beginning of disease, the last one has survived two years with cytostatic treatment. The disease was characterized by intermittent fever, hepatosplenomegaly and progressive pancytopenia as well as hyperbilirubinemia, hyperlipemia and hypofibrinogenemia. In addition to substantial enlargement of the liver and spleen prevailing autoptic findings were infectious complications due to severe immune defect or signs of hemorrhagic diathesis. Lymphocytes and histiocytes phagocytizing blood cells were increased in bone marrow, liver, spleen, often brain and further organs. Problems of differential diagnosis and pathogenesis were discussed.

The results are reported of a clinical and laboratory evaluation of the use of a random-access centrifugal analyzer linked to a personal computer in the management of the routine workload of a hemostasis laboratory. Over a three-month period, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin clotting time (TCT), and derived fibrinogen (Fib) were performed on a total of 929 samples. Included in the study were 448 samples from patients receiving anticoagulants (oral anticoagulants, 228; heparin, 166; heparin and warfarin, 130) and 351 samples from patients requiring coagulation screens (PT, APTT, TCT, Fib). Tests were done in parallel with tilt-tube manual techniques and the results correlated. The correlation coefficients were PT, 0.99; TCT, 0.72; APTT, 0.96; Fib, 0.97. Discrepancies were analyzed and were due to hypofibrinogenemia and hyperlipidemia. The poorer correlation coefficient of TCT was attributable both to lower reproducibility of the manual test and the effect of dysfibrinogenemia or FDPs in liver disease. In no case was an abnormality or diagnosis missed using the centrifugal analyzer. In several cases the increased sensitivity of the analyzer improved the detection of the lupus anticoagulant. The use of automation was accompanied by a major reduction in workload and reagent costs. The machine has been used to assay a wide range of coagulation tests by clot based and chromogenic substrate methods. In conclusion, a programmed centrifugal analyzer is a safe, efficient, and flexible way of automating routine coagulation tests. It widens the reportoire of tests performed in the Hemostasis laboratory by using a machine capable of being used in other areas of pathology.

Clinical course and histopathologic features of a typical case of familial hemophagocytic lymphohistiocytosis (FHLH) are presented. FHLH, initially known as familial hemophagocytic reticulosis (FHR), is rare and without proper treatment is invariably rapidly fatal, usually accompanied by fever, anorexia, vomiting, irritability and pallor. Sporadic examples with prolonged survival have been reported. Other significant findings include hepatosplenomegaly, progressive anemia, leukopenia, thrombocytopenia, hyperlipidemia and hypofibrinogenemia. Varying degrees of hemophagocytosis by widely disseminated histiocytes in different organs and structures is one hallmark of the disease. Hemophagocytosis may also occur in viral and bacterial infections and in certain malignant processes. Very high parental consanguinity in FHLH was mentioned in two relatively recent reports. A probable immunologic defect has been the focus of recent investigations. The genetic defect is believed to be transmitted as an autosomal recessive trait.

We describe four classical cases of familial hemophagocytic lymphohistiocytosis (FHL), a macrophage-related, autosomal recessive fatal disorder. Parental consanguinity was present in three cases. All patients presented with fever, neurological involvement of varying degrees, hepatosplenomegaly, cytopenias, deranged liver function tests, and coagulogram, hypofibrinogenemia (three cases), and hyperlipidemia (one case). An antemortem diagnosis could not be made, although it was suspected in one case. Necropsy (done in three cases and postmortem liver biopsy in one case) revealed classical features of FHL. Florid lymphohistiocytic infiltrate exhibiting hemophagocytosis was seen in the bone marrow, liver, spleen, lymph nodes and brain (examined in two case). In addition to this, focal infiltrates were seen in the kidneys, lung, pancreas, testes, adrenals, and skin. Marked lymphoid depletion was seen in one case in the lymph nodes and spleen.

We describe that high-dose methylprednisolone (20 mg/kg) can induce multifocal osteonecrosis (ON) in conjunction with thrombocytopenia, hypofibrinogenemia, and hyperlipemia. Detailed clinical and laboratory evaluations of coagulation system are recommended in those patients who develop manifestations of an abnormal lipid metabolism shortly after high-dose corticosteroid therapy. Moreover, we investigated the effects of the combination treatment with an anticoagulant (warfarin) plus a lipid-lowering agent (probucol) on prevention of steroid-induced osteonecrosis (ON) in this animal model. The incidence of ON in warfarin plus probucol (5%) was significantly lower than that observed in the control group (70%) (p <0.0001). Our results experimentally showed that the combined use of an anticoagulant and a lipid-lowering agent helps prevent steroid-induced ON in rabbits.
