Efficacy and Safety of TPO Receptor Agonists in the Treatment of Elderly ITP Patients

Primary immune thrombocytopenia (ITP) is an immune disorder characterized by decreased production and increased destruction of platelets. In recent years, with the in-depth exploration of its pathogenesis and the continuous influx of new drugs, the status of second-line treatment drugs, mainly TPO receptor agonists (TPO-RAs), has been continuously improved, which has brought great importance to the treatment and management of ITP patients. However, for elderly ITP patients with severe underlying diseases, poor hormone tolerance, severe adverse reactions or hormone contraindications, whether TPO receptor agonists can be used as the first-choice drug and its efficacy and safety are still lacking relevant research, and for elderly ITP patients There is a lack of uniform guidelines for the treatment and management of patients. Limited retrospective studies have shown that TPO receptor agonists have good safety and efficacy, and are expected to become the recommended drugs for the treatment of elderly patients with ITP. However, whether TPO receptor agonists can be directly used as the first-choice drug for newly diagnosed elderly ITP patients who are not suitable for first-line treatment and its efficacy are uncertain. This study will include newly diagnosed elderly ITP patients with hormonal contraindications or potential serious side effects of hormonal therapy, take the TPO-RA drug hetropoda as the first-choice treatment drug, and explore the effectiveness of hetrompopag in such patients and safety analysis. This study will provide new ideas and clinical basis for standardized and individualized treatment of elderly ITP patients, and provide practical experience for promoting the establishment of elderly ITP treatment guidelines.
