Abstract
Several therapeutic agents can cause thrombocytopenia by either immune-mediated or non-immune-mediated mechanisms. Non-immune-mediated thrombocytopenia is due to direct toxicity of drug molecules to platelets or megakaryocytes. Immune-mediated thrombocytopenia, on the other hand, involves the formation of antibodies that react to platelet-specific glycoprotein complexes, as in classic drug-induced immune thrombocytopenia (DITP), or to platelet factor 4, as in heparin-induced thrombocytopenia (HIT) and vaccine-induced immune thrombotic thrombocytopenia (VITT). Clinical signs include a rapid drop in platelet count, bleeding or thrombosis. Since the patient's condition can deteriorate rapidly, prompt diagnosis and management are critical. However, the necessary diagnostic tests are only available in specialized laboratories. Therefore, the most demanding step in treatment is to identify the agent responsible for thrombocytopenia, which often proves difficult because many patients are taking multiple medications and have comorbidities that can themselves also cause thrombocytopenia. While DITP is commonly associated with an increased risk of bleeding, HIT and VITT have a high mortality rate due to the high incidence of thromboembolic complications. A structured approach to drug-associated thrombocytopenia/thrombosis can lead to successful treatment and a lower mortality rate. In addition to describing the treatment of DITP, HIT, VITT, and vaccine-associated immune thrombocytopenia, this review also provides the pathophysiological and clinical information necessary for correct patient management.

Abstract
Chemotherapy-induced thrombocytopenia (CIT) is a common complication of the treatment of non-hematologic malignancies. Many patient-related variables (e.g., age, tumor type, number of prior chemotherapy cycles, amount of bone marrow tumor involvement) determine the extent of CIT. CIT is related to the type and dose of chemotherapy, with regimens containing gemcitabine, platinum, or temozolomide producing it most commonly. Bleeding and the need for platelet transfusions in CIT are rather uncommon except in patients with platelet counts below 25x109/L in whom bleeding rates increase significantly and platelet transfusions are the only treatment. Nonetheless, platelet counts below 70x109/L present a challenge. In patients with such counts, it is important to exclude other causes of thrombocytopenia (medications, infection, thrombotic microangiopathy, post-transfusion purpura, coagulopathy and immune thrombocytopenia). If these are not present, the common approach is to reduce chemotherapy dose intensity or switch to other agents. Unfortunately decreasing relative dose intensity is associated with reduced tumor response and remission rates. Thrombopoietic growth factors (recombinant human thrombopoietin, pegylated human megakaryocyte growth and development factor, romiplostim, eltrombopag, avatrombopag and hetrombopag) improve pretreatment and nadir platelet counts, reduce the need for platelet transfusions, and enable chemotherapy dose intensity to be maintained. National Comprehensive Cancer Network guidelines permit their use but their widespread adoption awaits adequate phase III randomized, placebo-controlled studies demonstrating maintenance of relative dose intensity, reduction of platelet transfusions and bleeding, and possibly improved survival. Their potential appropriate use also depends on consensus by the oncology community as to what constitutes an appropriate pretreatment platelet count as well as identification of patient-related and treatment variables that might predict bleeding.

Abstract
Disseminated intravascular coagulation (DIC) is a pathological systemic condition resulting from aberrant activation of the coagulation system. It is characterised by the release and activation of procoagulants into the blood, with an associated consumption coagulopathy. Its association with solid and haematological malignancies is well described in literature. This case describes an elderly man, known to have prostate cancer, who following transurethral resection of the prostate developed DIC with haematuria, spontaneous ecchymoses and mucosal bleeding. Subsequent investigations revealed a prostate-specific antigen (PSA) >1000 µg/L, and staging CT showed multiple sclerotic metastatic lesions affecting the thoracic and lumbar vertebra, as well as infiltration into his left femur. Coagulation normalised with blood products and vitamin K within 1 week, and the patient responded to antiandrogen therapy with a reduction in pain and PSA on discharge.

Abstract
BACKGROUND Disseminated intravascular coagulation (DIC) associated with solid tumors (DIC-ST) is often encountered in clinical practice. Patients with DIC-ST are usually in poor condition and have bleeding diathesis due to advanced or metastatic diseases. Although some affected patients are treated with heparin, this strategy has not been prospectively studied. Recombinant human soluble thrombomodulin (thrombomodulin alfa, TM-α) is a new anticoagulant developed in Japan. We conducted a prospective study that evaluated the efficacy and safety of TM-α in patients with DIC-ST. METHODS A prospective one-arm study with TM-α was conducted for DIC-ST. TM-α (380 U/kg) was given for 30 min intravenously once daily for 6-14 days. The primary efficacy endpoint was the DIC resolution rate. Change in DIC scores and improvement in bleeding symptoms and outcomes were also evaluated. Safety endpoints included the incidence of bleeding-related adverse events. RESULTS A total of 101 patients were treated with TM-α. The three main underlying malignant diseases were lung, stomach, and breast cancer, which accounted for 60 % of all patients. The DIC resolution rate was 34.0 % at the end of TM-α treatment. Improvement in DIC scores was seen in 55.2 % of patients, while only 22.9 % of patients had worsening of DIC scores. The overall survival rate was 55.4 % on day 28. The incidence of hemorrhage related to TM-α was 12.9 % until day 28. Cases of severe hemorrhage related to TM-α did not occur. CONCLUSIONS TM-α is effective and safe for DIC-ST. This agent is the treatment of choice for the management of DIC-ST.

Abstract
Objectives. To report the prevalence of consumptive coagulopathy in angiosarcoma patients seen at a single center. Methods. We retrospectively reviewed case records of 42 patients diagnosed with angiosarcoma at Mount Sinai Hospital between 2000 and 2013. Results. Seven patients (17%) met clinical criteria for disseminated intravascular coagulation (DIC) in absence of concomitant clinical states known to cause coagulopathy or myelosuppression. In all patients who received systemic antineoplastic therapy with resultant disease response or stability, DIC resolved in tandem with clinical improvement. DIC recurred at time of disease progression in all cases. Two patients had bulky disease, defined as diameter of largest single or contiguous tumor mass measuring 5 cm or more. All patients demonstrated an aggressive clinical course with short duration of disease control and demise within 1 year. In contrast, evaluation over the same period of 17 epithelioid hemangioendothelioma patients serving as a clinical control group revealed no evidence of DIC. Conclusion. Angiosarcomas can be associated with a consumptive coagulopathy arising in tandem with disease activity. Vigilance for this complication will be needed in the course of often aggressive multimodality therapy. The potential utility of coagulopathy as a prognostic biomarker will need to be explored in future studies.

Abstract
Patients with solid and hematologic malignancies presenting with major bleeding or thrombotic complications, potentially life-ending events in a cancer patient's clinical course, usually require admission to an intensive care unit (ICU), making their diagnosis and management even more important for the intensivist. Given the significant advances in the diagnosis and treatment of almost all types of cancers in recent years, the intensivist is likely to encounter an ever-increasing number of cancer patients in the ICU setting with these complications. Abnormal hemostasis can occur as a consequence of both the pathology and treatment of cancer. Because cancer can have multiple effects on hemostatic equilibrium, treatment of these complications can be more complex than in the general population. This article reviews the physiology of coagulation and fibrinolysis, with special attention to those aspects that are most frequently altered in the setting of malignancy. The pathophysiology of bleeding and thrombotic complications specific to critically ill cancer patients are then detailed, and the diagnostic and therapeutic strategies are discussed. Special emphasis is placed on new cancer medications that have an effect on hemostasis, and on novel clotting and anticoagulant agents that are available to the intensivist for the management of these patients.
