1/122. Multicentric warfarin-induced skin necrosis complicating heparin-induced thrombocytopenia.Two patients developed catastrophic multicentric skin necrosis while receiving warfarin to treat venous thromboembolism complicated by immune-mediated heparin-induced thrombocytopenia (HIT). Patient 1 developed skin necrosis involving the breasts, thighs, and face, as well as venous limb gangrene and bilateral hemorrhagic necrosis of the adrenal glands, resulting in death. The second patient developed bilateral mammary necrosis necessitating mastectomies, as well as skin necrosis involving the thigh. Neither patient had an identifiable hypercoagulable syndrome, other than HIT. HIT may represent a risk factor for the development of multicentric warfarin-induced skin necrosis (WISN).- - - - - - - - - - ranking = 1keywords = thrombocytopenia (Clic here for more details about this article) |
2/122. Spurious elevation of automated platelet counts in secondary acute monocytic leukemia associated with tumor lysis syndrome.The intent of this article is to describe the effect of tumor lysis on automated platelet counts in therapy-related, secondary acute monocytic leukemia. The first patient was a 69-year-old man with large cell carcinoma of the lung who developed acute monocytic leukemia 1(1/2) years after initiation of radiation and chemotherapy for his carcinoma. The second patient was a 72-year-old female with peripheral T-cell lymphoma who developed acute monocytic leukemia 1 year after initiation of chemotherapy for her lymphoma. Platelet counts were determined by the automated Coulter (STKS) counter. Both patients had clinical and laboratory evidences of tumor lysis syndrome and disseminated intravascular coagulation. The peripheral blood smears revealed numerous fragments of leukemic cells and apoptotic cells with pyknotic nuclei. The Coulter machine enumerated these cellular fragments as platelets, resulting in falsely elevated platelet counts. awareness of this laboratory artifact in secondary acute monocytic leukemia with tumor lysis syndrome is important so that potential life-threatening thrombocytopenia is not overlooked.- - - - - - - - - - ranking = 0.2keywords = thrombocytopenia (Clic here for more details about this article) |
3/122. disseminated intravascular coagulation in a patient treated with strontium-89 for metastatic carcinoma of the prostate.strontium-89 is effective in the palliation of bone pain caused by skeletal metastases. Its primary side effect is mild thrombocytopenia that typically recovers in 3 or 4 months. Subclinical disseminated intravascular coagulation is reported to be present in approximately 10% to 20% of patients with advanced prostate cancer. These patients may be at increased risk for severe marrow depression after radionuclide therapy for bone pain palliation. This report describes a patient with painful bony metastases resulting from prostate carcinoma. He had a normal platelet count and no clinical evidence of a coagulation disorder at the time of strontium-89 therapy, and a severe disseminated intravascular coagulation developed and lead to death after treatment. A normal platelet count before strontium-89 therapy does not preclude subsequent disseminated intravascular coagulation, and we support the Society of nuclear medicine's bone pain treatment procedure guideline that patients referred for bone palliation should be screened for disseminated intravascular coagulation before therapy.- - - - - - - - - - ranking = 0.2keywords = thrombocytopenia (Clic here for more details about this article) |
4/122. Extensive capillary malformation with a compensated coagulopathy.A 79-year-old male patient had an extensive vascular malformation, a thrombocytopenia and a low survival half-time of the thrombocytes without a bleeding problem. Recognition of this compensated coagulopathy is important, as it may become exacerbated into a bleeding disorder during periods of stress.- - - - - - - - - - ranking = 0.2keywords = thrombocytopenia (Clic here for more details about this article) |
5/122. Extensive late-onset primary subarachnoid hemorrhage in a preterm infant.Primary subarachnoid hemorrhage is a rare event in the preterm infant and is most often diagnosed at the postmortem examination. An extremely preterm infant who developed septicemia from staphylococcus aureus infection in the second postnatal week and presented with hypotension, metabolic acidosis, anemia, thrombocytopenia, and seizures is reported. Cranial ultrasound revealed a large extra-axial fluid collection involving the left parietal cortex that at postmortem examination was observed to be a large left-sided primary subarachnoid hemorrhage. The subarachnoid hemorrhage is most likely secondary to events associated with septic shock and probable disseminated vascular coagulopathy.- - - - - - - - - - ranking = 0.2keywords = thrombocytopenia (Clic here for more details about this article) |
6/122. association of hypercytokinemia in the development of severe preeclampsia in a case of hemophagocytic syndrome.Hemophagocytic syndrome (HPS) is a syndrome presenting with signs of persistent remittent fever, hepatosplenomegaly, pancytopenia, hepatic dysfunction, and disseminated intravascular coagulation (DIC) due to hypercytokinemia caused by activated T lymphocytes and macrophages. The mortality in adults is high and a small number of complicated cases during pregnancy have been reported. We report one HPS case that developed a remittent fever, leukocytopenia, and thrombocytopenia in the 2st week of pregnancy, and abnormal blood coagulation, hepatic dysfunction, and hypercytokinemia were found. Antibiotics and immunoglobulin were given but failed to improve clinical and laboratory findings. At the 24th week, the patient was diagnosed with DIC, and antithrombin (AT) concentrate was given. With the increase in plasma levels of AT, improvements were seen in both clinical signs and laboratory findings. bone marrow biopsies were carried out, and a diagnosis of HPS was made. Preeclampsia developed in the 27th week and it became severe. cesarean section was performed in the 29th week because of severe preeclampsia, intrauterine growth retardation (IUGR), and fetal distress. The courses of mother and newborn were uneventful. We discuss the mechanism of AT in the treatment of this syndrome and the association between this syndrome and severe preeclampsia. In conclusion, AT concentrate was very effective in suppressing cytokine production, and the possibility that severe preeclampsia developed because of hypercytokinemia, which may be one of the pathogeneses of severe preeclampsia and IUGR, was suggested.- - - - - - - - - - ranking = 0.2keywords = thrombocytopenia (Clic here for more details about this article) |
7/122. Chronic intravascular coagulation associated with chronic myelocytic leukemia. Use of heparin in connection with a surgical procedure.A women with philadelphia chromosome-positive chronic myelocytic leukemia lived nearly 12 years from the time of diagnosis. During most of this period she received no therapy, and marked cyclic oscillations in the white blood cell count were documented. The last two years of her illness were marked by a hemorrhagic disorder associated with hypofibrinogenemia, thrombocytopenia, increased plasma fibrinopeptide a concentration and markedly elevated serum levels of fibrin degradation products. The coagulation disorder was rapidly reversible on several occasions with heparin therapy. After treatment with heparin and platelet transfusions, the patient underwent successful resection of a large ovarian cyst with excellent hemostasis during the procedure. Postoperatively, the administration of heparin and platelets was discontinued and a large wound hematoma developed. After resumption of therapy with heparin and platelets, the remainder of her postoperative course was uneventful. The literature on the subject is reviewed and tentative guidelines are offered concerning the management of patients with intravascular coagulation who require diagnostic or therapeutic surgical procedures.- - - - - - - - - - ranking = 0.2keywords = thrombocytopenia (Clic here for more details about this article) |
8/122. Thrombotic thrombocytopenic purpura: a syndrome of intravascular platelet consumption.In four of five patients with thrombotic thrombocytopenic purpura (TTP) in whom serial tests of hemostatic function were performed, severe thrombocytopenia, normal plasma fibrinogen concentrations and mildly increased concentrations of fibrinogen/fibrin degradation products were observed. Widespread platelet thrombi were found in arterioles and capillaries. Fibrin could be seen around some of the platelet clumps and was the main component in a small number of the thrombi in two patients. The observations show that TTP is a disorder in which intravascular platelet consumption results in disseminated platelet thrombosis. The coagulation system is apparently activated secondarily to platelet aggregation and variable quantities of fibrin are incorporated into the thrombi. Clinical improvement resulted from combined therapy with corticosteroids, heparin and drugs that suppress platelet function.- - - - - - - - - - ranking = 0.2keywords = thrombocytopenia (Clic here for more details about this article) |
9/122. Virus-associated haemophagocytic syndrome responsive to steroid pulse therapy and double filtration plasmapheresis.We present an adult patient with haemophagocytic syndrome (HPS) successfully treated with a combination of steroid pulse therapy and double filtration plasmapheresis (DFPP). A 58-year-old male was admitted with high fever, severe renal dysfunction, liver dysfunction and an increased level of lactate dehydrogenase. A serological test for Epstein-Barr (EB) virus showed an elevation of EBNA-IgM antibody titre. There were increased haemophagocytic histiocytes in the bone marrow in addition to thrombocytopenia and disseminated intravascular coagulation (DIC) accompanied by organ dysfunction. EB virus associated haemophagocytic syndrome was diagnosed. On admission, interferon (IFN)-gamma, interleukin (IL)-6, IL-8, granulocyte colony-stimulating factor (G-CSF) and macrophage (M)-CSF were elevated, and were promptly normalized after steroid pulse therapy was initiated. G-CSF and M-CSF gradually decreased after DFPPs was started. To control hypercytokinaemia until treatment for the underlying disease is initiated, steroid pulse therapy and double filtration plasmapheresis are useful.- - - - - - - - - - ranking = 0.2keywords = thrombocytopenia (Clic here for more details about this article) |
10/122. Neonatal lupus erythematosus with microvascular hemolysis.A female, term newborn born to a mother with a history of idiopathic thrombocytopenic purpura and antinuclear antibodies, single-stranded A antibody, and IgM anticardiolipin antibodies presented with immune thrombocytopenia, disseminated intravascular coagulation (DIC), microangiopathic hemolytic anemia, and a characteristic lupus rash in the periorbital areas. She responded to combined treatment with dexamethasone and intravenous immunoglobulin (IVIG). At age 9 months, she was readmitted with severe thrombocytopenia, DIC, and microangiopathic hemolytic anemia. She again responded to IVIG. This suggests that microangiopathic hemolysis can be a presenting symptom in neonatal lupus erythematosus and that reoccurrence of the microangiopathic hemolysis may occur even after the disappearance of lupus antibodies.- - - - - - - - - - ranking = 0.4keywords = thrombocytopenia (Clic here for more details about this article) |
