NCT03212053

Brief Summary

There is no prospective study published on the Essential Thrombocythemia and the correlation between this specific disease, its complications and the biological variations observed. The aim of this study is to demonstrate a correlation between biological tests of haemostasis, as Multiplate analyser and thromboelastometry (ROTEM) and the occurrence of clinical complications, thrombosis and/or haemorrhage, in order to determine if this biological tests could be biological prognostic factors

    All haemorrhagic complications will be gathered by the investigators during the four months following the realization of Multiplate and ROTEM test

    every 4 months, up to 18 months

Secondary Outcomes (5)

  • Occurrence of thrombotic complications

    every 4 months, up to 18 months

  • Occurrence of haemorrhagic complications

    every 4 months, up to 18 months

  • Changes of tests results according to medical treatments

    every 4 months, up to 18 months

Study Arms (1)

Patients with Essential Thrombocythemia

OTHER

patients who come in consultation at diagnosis or during the follow-up for an Essential Thrombocythemia. They will have biological tests of haemostasis at each consultation (Multiplate, ROTEM, VASP)

Biological: biological tests of haemostasis at each consultation (Multiplate, ROTEM, VASP)

Interventions

Patients will have blood samples at each consultation (2 or 3 sampling tubes) in order to carry out systematically three biological tests

Patients with Essential Thrombocythemia
