[Adult immune thrombocytopenia and thrombopoietin receptor agonist: Ten years later]

Ten years after their licence in France, the use of the two thrombopoietin receptor agonists (TPO-RA), eltrombopag and romiplostim, has deeply modified the landscape of immune thrombocytopenia (ITP) treatment. In this review, we summarise data on efficacy and safety of these treatments during ITP, as well as their use in clinical practice. Their place in therapeutic strategy, the recent description of persistant remission after discontinuation of TPO-RA, and future new thrombopoietic agents are also discussed. Their use has progressively increased and early use at a newly diagnosed stage of the disease is under evaluation. However physician have to keep in mind that thromboembolism rates appear to be higher with TPO-RA treatment in ITP patients at high risk of thrombosis, and that data from "real-life" studies with very long term follow up are not available. Finally, the cost of these treatments should also be evaluated in future therapeutic strategies comparisons.
