Corticosteroid overuse in adults with immune thrombocytopenia: Cause for concern

Res Pract Thromb Haemost. 2021 Aug 25;5(6):e12592. doi: 10.1002/rth2.12592. eCollection 2021 Aug.ABSTRACTCorticosteroids remain a crucial component of first-line therapy for immune thrombocytopenia (ITP) due to low cost, high initial response rates, and acceptable short-term tolerability. However, extended and recurrent use of corticosteroids is associated with substantial toxicity. Survey studies indicate that >95% of patients with ITP treated with corticosteroids report adverse effects, more than one-third of whom require reduction or discontinuation of treatment. In light of the heavy treatment burden of prolonged corticosteroid exposure, clinical practice guidelines recommend limiting corticosteroid treatment to no more than 6 weeks in adults with ITP receiving initial therapy. For patients who require subsequent therapy, clinical practice guidelines recommend treatments more suitable for long-term disease control such as thrombopoietin receptor agonists, rituximab, other immune-modulating medications, or splenectomy, rather than repeated courses of corticosteroids. Despite these recommendations, real-world evidence suggests that corticosteroids remain the most frequently used treatment for adults with ITP, not only in the first line, but also in the second and third line. In this review, we summarize evidence on the efficacy, safety, and tolerability of corticosteroids; discuss the problem of overuse; and suggest strategies for curtailing the excessive use of corticos...
