Role of thrombopoietin stimulating agents(Eltrombopag and Romiplostim) in immune thrombocytopenia secondary to SLE

Abstract

Introduction: Immune thrombocytopenia is a frequent hematologic manifestation in systemic lupus erythematosus (SLE). Corticosteroids are the first line of treatment for moderate to severe thrombocytopenia in this disease, in conjunction with antimalarials or other immunosuppressants. In particular cases where the response to initial interventions is not achieved, secondline therapies with different mechanisms of action are available. Objective: This narrative review will focus on two thrombopoietin receptor agonist drugs (TPO-RA): eltrombopag and romiplostim, and their role in immune thrombocytopenia secondary to SLE. In addition, its pharmacological profile, dose and indications will be reviewed in the context of this disease. Methods: A literature search was conducted in different databases; scientific articles and guidelines were analyzed, both for SLE and immune thrombocytopenia. With the purpose of answering different clinical questions that constantly arise in the scene of daily practice. Results and conclusions: The use of TPO-RA stimulants is a therapeutic alternative for particular scenarios in patients with SLE and immune thrombocytopenia, however studies focused on this particular population are necessary to be able to make strong recommendations about its utility. Current data are extrapolated from primary immune thrombocytopenia.
