Abstract

Immune thrombocytopenia (ITP) is the most common clinical bleeding disorder with a high mortality rate and poor long-term survival quality in severe patients. There is controversy on how to choose the appropriate treatment. We systematically reviewed 19 randomized controlled trials (including 2615 participants) from January 1, 2015, to April 20, 2021. These investigations compared multiple drugs or their combinations in the therapeutic dose range for the treatment of ITP. The primary endpoint was based on the proportion of patients who responded to these therapies. The efficacy of eltrombopag plus rituximab, avatrombopag, dexamethasone plus anti-HP, and dexamethasone plus rhTPO was significantly higher than placebo (OR: 46.66, 29.44, 2.66, 1.86) or dexamethasone alone (OR: 46.22, 29.01, 2.22, 1.40). Placebo, oral immunosuppressants, and dexamethasone plus oseltamivir were less effective than the other ITP therapies tested. Eltrombopag plus rituximab may be the best choice when starting treatment for ITP.
