Plasma thrombomodulin (TM) levels were significantly elevated at disease onset in patients with thrombotic thrombocytopenic purpura (TTP) and disseminated intravascular coagulation (DIC), but was not in those with essential thrombocythemia and idiopathic thrombocytopenic purpura. However, in patients with TTP and DIC, TM levels decreased significantly after they achieved complete remission. In both TTP and DIC patients, plasma TM levels at onset in those with poor prognosis were higher than that in those with good prognosis. Among DIC patients, the plasma TM level was higher in those with organ failure than in those without, but there were no differences among patients with various underlying diseases associated with DIC. It is speculated that the plasma TM level reflects damage to vascular endothelial cells or organ failure and that it is useful in assessing prognosis for patients with DIC and TTP.

In hematological disorders, thrombocytopenia is frequently observed, and it is sometimes difficult to diagnose the underlying disease. In this symposium, laboratory tests for platelet abnormality were reviewed. Tests for platelet aggregation were reported to be important for the diagnosis of platelet dysfunction. Thrombocytopenia is caused by disseminated intravascular coagulation (DIC), thrombotic microangiopathy (TMA), heparin-induced thrombocytopenia (HIT), antiphospholipid syndrome (APS), idiopathic thrombocytopenic purpura (ITP), etc. As DIC is classified according to the degree of fibrinolysis, it was stated that the measurement of hemostatic molecular markers was further required. TMA is caused by abnormality of ADAMTS13, verotoxin, DIC, etc. HIT is diagnosed by anti-PF4 antibody, but its specificity is not high. Further investigation of TMA and HIT is required. APS is one of the most important diseases which cause thrombosis or abortion, suggesting that a differential diagnosis of APS is important. It was reported that diagnostic criteria of ITP have been established using a new antibody assay for platelets, immature platelet fractions, thrombopoietin, etc. In myeloproliferative disorders such as polycythemia vera and essential thrombocythemia, the mutation of JAK2 V617F was reported to be an important risk factor for thrombosis.

Thrombohaemorrhagic syndrome is a clinical syndrome manifesting with concurrent bleeding and thrombosis. It is associated with a range of pathological states, typically with myeloproliferative diseases, paraproteinaemia, liver disease as well as disseminated intravascular coagulation and similar syndromes (so called DIC-like syndrome). Thrombohaemorrhagic syndrome might be a symptom of chronic myeloproliferations, particularly if these are associated with thrombocythemia. It is most frequently linked to essential thrombocythemia. However, in this disease, it seems that the clinical symptoms of bleeding and thrombosis might not be directly determined by the number of platelets, as it would suggest itself, but that this can be consequent to other changes. These may include predisposition to thrombophilia, cardiovascular risk, leukocytosis etc. as well as, for example, platelet dysfunction. The present study focuses on platelet dysfunction in conjunction with clinical symptoms of bleeding and thrombosis.

We report a 67-year-old woman with essential thrombocytosis who developed cerebral infarction and heparin-induced thrombocytopenia during treatment for the cerebral infarction. She developed additional cerebral infarcts, acute femoral artery occlusion, and thrombophlebitis of her lower extremities. She was successfully treated with argatroban. This is the first report of a patient with essential thrombocytosis who developed heparin-induced thrombocytopenia and serious conditions, which included multiple thromboembolisms and coagulation disorders mimicking disseminated intravascular coagulation.

Essential thrombocythemia is well-known to transform to other myeloid disorders, such as leukemia; however, the risk for development of lymphoma is not as well studied. This case report discusses a 76-year-old man with a history of prefibrotic post-essential thrombocythemia myelofibrosis on ruxolitinib, who developed anemia, thrombocytopenia, and leukocytosis with peripheral blasts. Results of a bone marrow biopsy and PET and CT scans revealed stage IV leukemic diffuse large B-cell lymphoma. Several days after cessation of ruxolitinib, the patient developed fevers, hypotension, and low-grade disseminated intravascular coagulation, and subsequently developed spontaneous tumor lysis syndrome, which resulted in death. This case is unique in several aspects: it highlights the rare possibility of lymphomatous transformation of myeloproliferative disorders, an unusual presentation of lymphoma masquerading as leukemia, and the possibility of ruxolitinib withdrawal syndrome. Additionally, this case serves as a reminder that the use of novel therapies should be adopted after a thorough assessment of long-term risks, including those associated with abrupt withdrawal.
